一对刹闸815各自安装在两个支杆811、812上，每一刹闸815的抱闸面为圆弧面。较佳，刹闸上各自设有一橡胶垫，该橡胶垫最好与抱闸面有同样的面积，并通过热压施贴到刹闸815的表面上，使用时可直接与槽轮接触。A pair of brakes 815 are respectively mounted on twopoles 811, 812, and the brake surface of each brake 815 is an arc surface. Preferably, each of the brakes is provided with a rubber pad, which preferably has the same area as the brake surface, and is applied to the surface of the brake 815 by hot pressing, so that it can directly contact the sheave during use.

弹簧装置816安装在刹闸815上方两支杆811、812之间。弹簧装置816包括两个支轴826和836、两个保持件846、856和一弹簧866，其中，保持件646、856为圆形盘，它们各自固定于支轴626、836的一端上，支轴另一端则通过紧固件分别固定在两支杆811、812上，所述弹簧为螺旋弹簧866，其两端分别固定在两个保持件646、856上并位于它们之间。The spring device 816 is installed between the twostruts 811 and 812 above the brake 815 . The spring device 816 comprises two supporting shafts 826 and 836, two holders 846, 856 and a spring 866, wherein the holders 646, 856 are circular discs, which are respectively fixed on one end of the supporting shafts 626, 836, and the supporting parts The other end of the shaft is respectively fixed on the twopoles 811, 812 by fasteners. The spring is a coil spring 866, the two ends of which are respectively fixed on the two holders 646, 856 and located between them.

支撑件817安装在底座406的一侧，安装方向是向着底座外。The supporting member 817 is installed on one side of thebase 406, and the installation direction is toward the outside of the base.

制动液压缸818安装在支撑件817上，该液压缸的活塞杆828与偏心摆杆813的另一端的安装孔834连接，所述制动液压缸连接的液压系统的电磁阀。The brake hydraulic cylinder 818 is installed on the support member 817, the piston rod 828 of the hydraulic cylinder is connected with the mounting hole 834 at the other end of the eccentric swing rod 813, and the brake hydraulic cylinder is connected with the solenoid valve of the hydraulic system.

该液压制动装置的工作原理是：在破碎机运行时，液压系统的电磁阀或换向阀通电，制动液压缸的活塞杆因无杆腔进油而伸出，并推动偏心摆杆813挠着与支杆的轴转动，进而通过偏心摆杆813与拉杆814的连接轴的偏心转动使两个支杆811、812之间的距离增大，同时使支杆811、812相对地绕其下的轴孔829中的轴向外转动，以拉动支轴817相对向外移动，并对弹簧818进行拉伸以及使两刹闸815各自脱离与槽轮404的接合面414而分离一定距离，以便槽轮404的正常转动。在破碎机工作时遇到非破碎物等需要制动时，电磁阀失电，制动液压缸回油，活塞杆缩进液压缸的同时偏心摆杆813被下拉，弹簧818拉伸被解除，并依靠弹簧818的回复力将两个支杆811、812相对地向内移动，在弹簧818拉伸被解除的瞬时，使偏心摆杆813快速顺时钟方向转动，接着弹簧818将弹性力完全释放而压紧刹闸而抱住槽轮404。整个制动时间，设定在破碎机主机停止运行后2分钟以内，以保证设备的安全性。所述刹闸815的抱闸面上设有橡胶垫，橡胶垫附装抱闸面并在制动上其可与槽轮404一侧的光滑的表面414相对柔性紧密结合。The working principle of the hydraulic brake device is: when the crusher is running, the solenoid valve or reversing valve of the hydraulic system is energized, and the piston rod of the brake hydraulic cylinder is stretched out due to the oil entering the rodless chamber, and pushes the eccentric swing rod 813 Rotate with the axis of the pole, and then the distance between the twopoles 811, 812 is increased through the eccentric rotation of the connecting shaft of the eccentric swing link 813 and thepull rod 814, and at the same time, thepoles 811, 812 are relatively rotated around them. The shaft in the lower shaft hole 829 rotates outwards to pull the supporting shaft 817 to move relatively outward, and stretches the spring 818 and separates the two brakes 815 from thejoint surface 414 with thesheave 404 for a certain distance. For the normal rotation of thesheave 404. When the crusher encounters non-broken objects and needs to be braked, the solenoid valve is powered off, and the brake hydraulic cylinder returns oil. When the piston rod retracts into the hydraulic cylinder, the eccentric swing rod 813 is pulled down, and the stretch of the spring 818 is released. And rely on the restoring force of the spring 818 to move the twostruts 811, 812 relatively inward. When the tension of the spring 818 is released, the eccentric pendulum 813 is quickly rotated clockwise, and then the spring 818 completely releases the elastic force. And press brake brake and embracesheave 404. The entire braking time is set within 2 minutes after the main machine of the crusher stops running to ensure the safety of the equipment. The brake surface of the brake 815 is provided with a rubber pad, and the rubber pad is attached to the brake surface and can be relatively flexible and closely combined with thesmooth surface 414 on one side of thesheave 404 during braking.

制动液压缸连接的换向阀，在压力传感器30压力信号达到或大于18MPa时，或在系统自动运行情况下，按急停按钮；使换向阀同时失电，主液压缸停，在15秒钟后破碎机停止运行，2分钟后破碎机制动器抱闸。For the reversing valve connected to the brake hydraulic cylinder, when the pressure signal of thepressure sensor 30 reaches or exceeds 18MPa, or when the system is running automatically, press the emergency stop button; After 2 seconds, the crusher stops running, and after 2 minutes, the brake of the crusher is locked.

其下通过轴可转动地安装在电动机一侧基础的底座406上并位于槽轮404两侧的两根支杆811、812，通过轴架设在支杆811(812)之一上的一偏心摆杆813、通过轴安装在另一支杆812(811)和偏心摆杆813之间的一拉杆814、分别相对地安装在两支杆811、812中间的一对刹闸815和安装在刹闸上方两支杆之间的一弹簧装置，该弹簧装置包括一固定在偏心摆杆813一侧的支杆之一上固定板816，一固定在另一支杆上的带突出头部的支轴817，一套在支轴上的弹簧818、一一端安装在基础的底座406上而另一端、即其活塞杆连接于偏心摆杆813的液压缸819以及通过管道连接液压缸819的有杆和无杆腔的电磁阀820。该液压制动装置的工作原理是：在破碎机运行时，电磁阀820通电，液压缸819的活塞杆因无杆腔进油而伸出，并推动偏心摆杆813挠着与支杆的安装轴转动，进而通过偏心摆杆813与拉杆814的连接轴的偏心转动使两个支杆811、812之间的距离增大，同时使支杆811、812相对地绕其下的轴向外转动，以拉动支轴817由其突出头对弹簧818进行压缩以及使两刹闸815各自与槽轮404的接合面分离一定距离，以便槽轮404的正常转动。在破碎机工作时遇到非破碎物等需要制动时，电磁阀失电，除弹簧818压缩被解除，两支杆811、812以使支杆绕其下的轴向外转动的相反方向将它们向内拉，同时使偏心摆杆813顺时钟方向转动和使推动活塞杆下移，弹簧818将完全压紧刹闸。整个制动时间，设定在破碎机停止运行后2分钟以内，以保证设备的安全性。It is rotatably installed on thebase 406 of one side of the motor by the shaft and is positioned at the two struts 811,812 on both sides of thesheave 404, and an eccentric pendulum mounted on one of the struts 811 (812) by the shaft. Rod 813, apull rod 814 that is installed between another pole 812 (811) and the eccentric swing bar 813 through a shaft, a pair of brake brakes 815 that are respectively installed in the middle of the twopoles 811, 812 and are installed on the brake brake A spring device between the two poles above, the spring device comprises a fixed plate 816 fixed on one of the poles on one side of the eccentric swing bar 813, a fulcrum with a protruding head fixed on the other pole 817, a set of spring 818 on the fulcrum, one end is installed on thebase 406 of the foundation and the other end, that is, its piston rod is connected to the hydraulic cylinder 819 of the eccentric swing rod 813 and the rod connected to the hydraulic cylinder 819 by the pipeline And the solenoid valve 820 of the rodless cavity. The working principle of the hydraulic brake device is: when the crusher is running, the solenoid valve 820 is energized, and the piston rod of the hydraulic cylinder 819 is stretched out due to the oil entering the rodless cavity, and the eccentric swing rod 813 is pushed to scratch the installation of the support rod. The shaft rotates, and the eccentric rotation of the connecting shaft between the eccentric swing rod 813 and thepull rod 814 increases the distance between the twostruts 811, 812, and at the same time makes thestruts 811, 812 relatively rotate outward around the axis below them. , to pull the fulcrum 817 to compress the spring 818 by its protruding head and to separate the joint surfaces of the two brakes 815 from thesheave 404 by a certain distance, so that thesheave 404 can rotate normally. When the crusher encounters non-broken objects and needs to be braked when the crusher is working, the solenoid valve is de-energized, and the compression of the spring 818 is released. They pull inwardly, make eccentric fork 813 rotate clockwise and make to push piston rod to move down simultaneously, and spring 818 will fully compress brake brake. The entire braking time is set within 2 minutes after the crusher stops running to ensure the safety of the equipment.

所述刹闸815包括抱闸825和橡胶垫835，橡胶垫835附装抱闸825上并在制动上其可与槽轮404一侧的光滑的表面相对柔性紧密结合。The brake 815 includes a brake 825 and a rubber pad 835. The rubber pad 835 is attached to the brake 825 and can be tightly combined with the smooth surface on one side of thesheave 404 for braking.

请参阅图14至图18，图中示出了液压过铁保护系统的工作原理图，其中，两个主液压缸33并联，由分流集流阀32和机械导向共同控制其运动的同步性。Please refer to FIG. 14 to FIG. 18 , which show the working principle diagram of the hydraulic over-iron protection system, in which two mainhydraulic cylinders 33 are connected in parallel, and the synchronism of their movement is jointly controlled by the divider and flowvalve 32 and the mechanical guide.

主换向阀27的左位接入工作时，活塞前行，遇阻停止后，泵继续向蓄能器28充液，压力随之升高，直至达到设定压力，使双液压缸的前推力达到预定的2.68×10⁶N，此时控制系统根据压力传感器21的压力信号令全部电磁铁失电，电磁溢流阀卸荷(可考虑关闭泵，调试中视泵启停频率决定)。如果一段时间工作后，蓄能器中蓄能不足，压力降低，根据压力传感器30的压力信号使主换向阀27左位接入，泵源重新向蓄能器充液。When the left position of the main reversingvalve 27 is connected to work, the piston moves forward, and after stopping when encountering resistance, the pump continues to fill theaccumulator 28, and the pressure rises accordingly until it reaches the set pressure, so that the front of the double hydraulic cylinder The thrust reaches the predetermined 2.68×10⁶ N. At this time, the control system de-energizes all the electromagnets according to the pressure signal of thepressure sensor 21, and the electromagnetic overflow valve unloads (it may be considered to shut down the pump, which depends on the pump start-stop frequency during debugging). If after working for a period of time, the energy storage in the accumulator is insufficient and the pressure drops, according to the pressure signal of thepressure sensor 30, the left position of the main reversingvalve 27 is connected, and the pump source refills the accumulator.

在破碎过程中，如主液压缸因破碎力增大而产生后退趋势，因液控单向阀29封堵了油路，使液压缸无杆腔压力升高，达到溢流阀31的调定压力后，方可由该阀溢流而允许主液压缸后退，此时后退的阻力由溢流阀31的调压决定(最高可达到3.54×10⁶N，)。此压力信号由压力传感器30传输至控制系统，控制系统执行“过铁”动作。During the crushing process, if the main hydraulic cylinder tends to retreat due to the increase of the crushing force, the oil circuit is blocked by the hydrauliccontrol check valve 29, so that the pressure in the rodless cavity of the hydraulic cylinder rises to reach the setting of theoverflow valve 31. After pressure, the main hydraulic cylinder can be allowed to retreat due to the relief of the valve. At this time, the resistance of the retreat is determined by the pressure regulation of the relief valve 31 (up to 3.54×10⁶ N). This pressure signal is transmitted to the control system by thepressure sensor 30, and the control system executes the action of "passing iron".

主换向阀27右位接入工作时，供油压力打开液控单向阀，主液压缸有杆腔进油后退，由节流阀26控制其合适的后退速度。如果此时主液压缸33受到很大的后退外力，则节流阀26能阻止其快速后退，而当后退外力更大，至液压缸无杆腔压力达到溢流阀31调定压力时，则主液压缸仍会因溢流阀31溢流而快速后退，这就可保证系统免受损坏。When the right position of main reversingvalve 27 is connected to work, the oil supply pressure opens the hydraulic control check valve, and the main hydraulic cylinder has a rod cavity to feed oil and retreat, and thethrottle valve 26 controls its suitable retreat speed. If the mainhydraulic cylinder 33 is subjected to a large retreat external force at this time, thethrottle valve 26 can prevent it from rapidly retreating, and when the retreat external force is greater until the pressure in the rodless cavity of the hydraulic cylinder reaches the set pressure of therelief valve 31, then The main hydraulic cylinder will still retreat quickly due to the overflow of theoverflow valve 31, which can ensure that the system is not damaged.

泵源14～16设置两套，分别独立工作。一套工作，另一套备用。There are two sets of pump sources 14-16, which work independently. One set works and the other is spare.

液压过铁保护系统动作及其控制方式：The action and control mode of the hydraulic iron protection system:

在正常工作过程中，先使主换向阀左位接入(IDT“+”)，主缸33右行，行至行程终端后，蓄能器充压至设定压力，压力传感器30的压力信号确定破碎机主机可以开始工作。In the normal working process, the main reversing valve is first connected to the left (IDT "+"), and themaster cylinder 33 moves to the right. After reaching the end of the stroke, the accumulator is charged to the set pressure, and the pressure of thepressure sensor 30 The signal confirms that the crusher host can start working.

在过铁工作过程中，若主缸因破碎力过大而退让，则压力传感器30出现高压(＞18.5MPa)信号，说明有非破碎物存在，控制系统将执行“过铁”动作。其过程为：关闭进料口，并使液压过铁保护系统主换向阀27切换至右位工作，使主缸33后退，至主缸活塞左侧的突柱(另附说明)进入左缸盖沉孔时，压力传感器34出现高压(＞19MPa)信号，说明已“退至排料口250mm”，然后立即使主缸恢复前行并计时，至压力传感器30达到设定压力后，进料口恢复进料。During the working process of iron passing, if the main cylinder retreats due to excessive crushing force, a high pressure (>18.5MPa) signal will appear on thepressure sensor 30, indicating that there are non-broken objects, and the control system will execute the "iron passing" action. The process is as follows: close the feed inlet, switch the main reversingvalve 27 of the hydraulic iron protection system to the right position, and make themaster cylinder 33 retreat until the post on the left side of the master cylinder piston (attached instructions) enters the left cylinder When the counterbore is covered, a high-pressure (>19MPa) signal appears on thepressure sensor 34, indicating that it has "retracted to the discharge port 250mm", and then the master cylinder is immediately resumed and timed until thepressure sensor 30 reaches the set pressure. The mouth resumes feeding.

在清除超大非破碎物中，在“过铁”后主缸前行动作的30秒(调试确定)内，若压力传感器30又出高压信号(＞18.5MPa)，说明主缸前行遇阻，非破碎物并未排出，则控制系统立即使主机停止运转和制动。主机停止后(由调试确定主机停车制动时间)，液压过铁保护系统转为手动控制，点动按钮控制主液压缸后退，及电磁换向阀26左位接入，可使主液压缸后退至行程终端，然后由人工清除超大的非破碎物。完成后整个系统即可恢复“正常工作”。In the process of clearing oversized non-broken objects, if thepressure sensor 30 sends out a high-pressure signal (>18.5MPa) within 30 seconds of the master cylinder’s forward movement after the “over-iron” (debugged), it means that the master cylinder’s forward movement is blocked. If the non-broken objects are not discharged, the control system immediately stops and brakes the main machine. After the main engine stops (determined by debugging to determine the main engine parking braking time), the hydraulic iron protection system is switched to manual control, the jog button controls the main hydraulic cylinder to retreat, and the left position of the electromagnetic reversingvalve 26 is connected to make the main hydraulic cylinder retreat To the end of the stroke, and then remove the oversized non-broken objects manually. Once complete, the entire system can resume "normal operation".

在需要停止工作(或急停)时，先控制进料口关闭、再使主机停转，液压过铁保护系统换向阀的电磁铁全部处于“失电”状态，并转为手动控制。When it is necessary to stop working (or emergency stop), firstly control the closing of the feed inlet, and then stop the main machine, and all the electromagnets of the reversing valve of the hydraulic iron protection system are in the "power-off" state, and turn to manual control.

在工作过程中，如果泵源发生故障，可由压力信号使控制系统关闭故障泵的电机，启动备用泵电机，立即恢复工作。During the working process, if the pump source fails, the pressure signal can make the control system shut down the motor of the faulty pump, start the standby pump motor, and resume work immediately.

在调整颚板出料口尺寸时，先点动控制使主缸33后退至行程终端(电磁换向阀27左位接入)，松开活塞杆与调整垫片的机械连接(见机械结构图)后，控制换向阀22右位和19左位接入，使双辅助缸21伸出顶起颚板(此前需确定主缸33已处退后位置)，换向阀19切至中位锁住辅助缸21，全部电磁铁失电，液压过铁保护系统处于卸荷状态，然后可进行更换垫片操作。操作完成后，必须先将换向阀19切换至右位，控制辅助缸21缩回至行程终端，再切回中位，机械连接完成后，可将电磁换向阀22切换至左位，主系统恢复工作。When adjusting the size of the discharge port of the jaw plate, first jog the control to make themaster cylinder 33 retreat to the end of the stroke (the electromagnetic reversingvalve 27 is connected to the left), and loosen the mechanical connection between the piston rod and the adjusting gasket (see the mechanical structure diagram ), control the access of the right position of the reversingvalve 22 and the left position of 19, so that the doubleauxiliary cylinder 21 stretches out to jack up the jaw plate (before it must be determined that themain cylinder 33 is in the retreat position), and the reversingvalve 19 is switched to the neutral position Lock theauxiliary cylinder 21, all the electromagnets are de-energized, the hydraulic over-iron protection system is in an unloaded state, and then the pad replacement operation can be performed. After the operation is completed, the reversingvalve 19 must be switched to the right position first, theauxiliary cylinder 21 is controlled to retract to the end of the stroke, and then switched back to the neutral position. After the mechanical connection is completed, the electromagnetic reversingvalve 22 can be switched to the left position, and the main The system resumes working.

有关液压过铁保护系统操作说明：通过换向阀19和22所接的辅助液压缸20，是为调整出料口尺寸时所用，辅助缸伸出时顶开动颚，以便更换垫片。Instructions for the operation of the hydraulic over-iron protection system: the auxiliaryhydraulic cylinder 20 connected to the reversingvalve 19 and 22 is used for adjusting the size of the discharge port.

有关闭边排料口的调整：闭边排料口为100±30mm，通过调整垫片的增、减来进行调整。Adjustment of the discharge opening on the closed side: the discharge opening on the closed side is 100±30mm, and it is adjusted by adjusting the increase or decrease of the shim.

在主机停止，主液压缸33退回的状态下，先卸下活塞杆与调整垫片的机械连接，然后换向阀22右位接入(4DT“-”)，此时可点动控制换向阀19左位接入(5DT“+”)，使两个辅助缸21伸出顶起肘板及动颚，释放点动按钮后，换向阀19处于中位，将辅助缸21锁住，即可手动调整垫片。When the main engine is stopped and the mainhydraulic cylinder 33 is retracted, first remove the mechanical connection between the piston rod and the adjusting gasket, and then the reversingvalve 22 is connected to the right (4DT "-"), and the reversing can be controlled by jogging at this time The left position of thevalve 19 is connected (5DT "+"), so that the twoauxiliary cylinders 21 stretch out to jack up the toggle plate and the movable jaw. After the jog button is released, the reversingvalve 19 is in the middle position, and theauxiliary cylinder 21 is locked. The shims can then be adjusted manually.

调整完成后，点动控制换向阀19右位接入(6DT“+”)，使辅助缸21退回，释放点动按钮后，换向阀19仍回中位，锁住辅助缸33，完成活塞杆与调整垫片的机械连接后，再将换向阀22左位接入(4DT“+”)，此时两个辅助缸处于“退回浮动、前进锁定”状态。After the adjustment is completed, the right position of the jogcontrol reversing valve 19 is connected (6DT "+") to make theauxiliary cylinder 21 return. After the jog button is released, the reversingvalve 19 still returns to the neutral position, and theauxiliary cylinder 33 is locked. After the mechanical connection between the piston rod and the adjusting gasket, the reversingvalve 22 is connected to the left (4DT "+"). At this time, the two auxiliary cylinders are in the state of "back floating, forward locking".

主系统自动控制运行：The main system automatically controls the operation:

先人工开启液压泵电源，注意观察液压泵运转是否正常。First manually turn on the power supply of the hydraulic pump, and pay attention to observe whether the hydraulic pump is running normally.

启动“破碎机运行”后，控制系统执行如下操作程序。After the "crusher operation" is started, the control system executes the following operating procedures.

(1)换向阀22左位接入(4DT“+”)。(1) The reversingvalve 22 is connected to the left (4DT "+").

(2)换向阀27左位接入(1DT“+”)使主液压缸伸出。(2) The left position of the reversingvalve 27 is connected (1DT "+") to extend the main hydraulic cylinder.

(3)等待一分钟(调试确定)，检测压力传感器30是否达到预定工作压力。(3) Wait for one minute (commissioning is confirmed), and check whether thepressure sensor 30 reaches the predetermined working pressure.

“Y”——进入下一步，同时切换电磁铁“全失电”"Y"——Go to the next step, and switch the electromagnet to "all power off" at the same time

“N”——报警"N" - alarm

(4)主电机起动(动颚运行)。(4) The main motor starts (moving jaw runs).

(5)进料口放料。(5) Discharging at the feed port.

有关“过铁”控制：Regarding the "over iron" control:

在破碎机自动运行过程中，若压力传感器30出现高压信号(溢流阀31的调定压力)，说明被破碎物料中存在非破碎物，主液压缸已因破碎力过大而开始出现被动后退的过载保护动作，则控制系统执行“过铁”动作。其过程如下：During the automatic operation of the crusher, if thepressure sensor 30 shows a high-pressure signal (the setting pressure of the overflow valve 31), it means that there are non-broken objects in the crushed material, and the main hydraulic cylinder has begun to retreat passively due to excessive crushing force. If the overload protection action is activated, the control system will execute the "over-iron" action. The process is as follows:

1)控制进料口关闭，停止放料。1) Control the feed port to close and stop discharging.

2)换向阀27右位接入(2DT“+”)，主液压缸后退。2) The right position of the reversingvalve 27 is connected (2DT "+"), and the main hydraulic cylinder moves backward.

3)检测压力传感器34的压力信号，出现稳定的高压信号(＞19MPa)时，说明主液压缸后退至排料口250mm已经到位，立即控制主换向阀27左位接入(1DT“+”)，使主液压缸前行。3) Detect the pressure signal of thepressure sensor 34. When a stable high-pressure signal (>19MPa) appears, it means that the main hydraulic cylinder has retreated to the discharge port 250mm and is in place. Immediately control the left position of the main reversingvalve 27 to connect (1DT "+" ) to make the main hydraulic cylinder move forward.

4)在液压缸前行时进行计时监视，30秒(调试确定)内压力传感器30、34均无高压信号，30秒后，压力传感器信号达到设定工作压力时，进料口恢复放料，系统继续“自动运行”。4) Timing monitoring is carried out when the hydraulic cylinder is moving forward. There is no high-pressure signal from thepressure sensors 30 and 34 within 30 seconds (debugged). After 30 seconds, when the pressure sensor signal reaches the set working pressure, the feeding port resumes discharging. The system continues to "automatically run".

5)如果上款动作过程中，压力传感器30、34中任意之一在30秒(调试确定)内出现高压信号，则立即控制主机停转、制动，控制系统退出“自动运行”状态，切换为人工控制，并发出声光信号，警示有超大非破碎物(＞250mm)存在。5) If any one of thepressure sensors 30 and 34 has a high-voltage signal within 30 seconds (determined after debugging) during the action of the previous paragraph, immediately control the main engine to stop and brake, and the control system exits the "automatic operation" state, and switches to It is controlled manually and sends out sound and light signals to warn of the existence of oversized non-broken objects (>250mm).

有关人工清除超大非破碎物：For manual removal of oversized non-broken objects:

控制系统发出声光信号，表示存在超大非破碎物时，待主机停稳，点动控制主换向阀27右位接入(2DT“+”)，使主液压缸后退，同时按钮控制换向阀36左位接入(3DT“+”)，使主液压缸退至行程最左端，然后关闭液压过铁保护系统控制电源，即可进行人工清除超大非破碎物。完成后重复“2.主系统自动控制运行”。The control system sends out sound and light signals, indicating that there are super large non-broken objects, wait for the main engine to stop, jog the right position of the main reversingvalve 27 to connect (2DT "+"), so that the main hydraulic cylinder moves backward, and the button controls the reversing at the same time The left position ofvalve 36 is connected (3DT "+"), so that the main hydraulic cylinder retreats to the leftmost end of the stroke, and then the control power supply of the hydraulic iron over-iron protection system is turned off, and the oversized non-broken objects can be manually removed. Repeat "2. Main system automatic control operation" after completion.

系统停止工作：System stops working:

破碎机需要停止工作时，按钮“停止工作”，控制系统控制如下动作：When the crusher needs to stop working, press the button "stop working", and the control system controls the following actions:

关闭进料口停止放料；Close the feed port to stop discharging;

主机停止运转；The host stops working;

主机制动停稳后，控制换向阀27右位接入(2DT“+”)，使主液压缸后退；After the main engine brakes and stops, control the right position of the reversingvalve 27 to connect (2DT "+") to make the main hydraulic cylinder retreat;

压力传感器34出高压信号时，全部电磁铁均切至失电状态，退出“自动控制运行”状态；When thepressure sensor 34 sends out a high-voltage signal, all the electromagnets are switched to the power-off state and exit the "automatic control operation" state;

At this time, it is necessary to avoid any malfunction of the machine equipment. In this regard, this design has the following measures:

垫片调整时，必须确保双辅助缸21必须锁定，主缸33位于退回位置，且不能有任何动作的可能，要求操作人员在进入机器时，必须关闭液压过铁保护系统控制电源和关闭液压泵，在所有换向阀的电磁铁均处失电状态时，正好能保证上述要求，同时也保证在操作过程中，突然的断电亦不会出现误动作。When adjusting the gasket, it must be ensured that the doubleauxiliary cylinder 21 must be locked, and themain cylinder 33 is in the retracted position, and there is no possibility of any movement. It is required that the operator must turn off the control power of the hydraulic over-iron protection system and the hydraulic pump when entering the machine , when the electromagnets of all reversing valves are in the de-energized state, the above-mentioned requirements can be guaranteed, and at the same time, it is also guaranteed that there will be no malfunction when the power is suddenly cut off during the operation.

操作人员在靠近机器进行操作时，其他人不得开启液压控制电源。规定开启液压过铁保护系统的控制电源时，必须用钥匙开启，并要求有持续数秒钟的声光信号。万一由他人误开启了液压过铁保护系统控制电源，此时液压过铁保护系统尚不会立即产生动作变化，而声光信号可以提醒操作人员立即采取自我保护措施。When the operator is operating close to the machine, others are not allowed to turn on the hydraulic control power. It is stipulated that when the control power supply of the hydraulic over-iron protection system is turned on, it must be turned on with a key, and an audible and visual signal that lasts for several seconds is required. In case someone accidentally turns on the control power of the hydraulic iron over-iron protection system, the hydraulic over-iron protection system will not immediately change its action, but the sound and light signal can remind the operator to take immediate self-protection measures.
