背景技术Background Art
在现如今的管道行业中，想要测量管道内的液体压力度，通常会在安装管道时在管道的需要测量段预留测量段管道，需要测量时，将测量段管道取下来，安装上检测装置在该部位进行检测，通常情况下，检测装置中的标准器需要人工通过检测装置上的一个标准器输送管道伸入到待测管道内检定位置进行检测，人工将标准器插入标准器输送管时，难免会发生手部抖动，使得标准器的底部探头贴合在标准器输送管的内壁，或者标准器的底部探头与待检测管道内的水流之间相对抖动影响测量准确性。In today's pipeline industry, if you want to measure the liquid pressure in a pipeline, you usually reserve a measuring section of the pipeline at the section where the measurement is required when installing the pipeline. When measurement is required, the measuring section of the pipeline is removed and a detection device is installed at that location for detection. Usually, the standard in the detection device needs to be manually inserted into the calibration position in the pipeline to be tested through a standard delivery pipe on the detection device for detection. When manually inserting the standard into the standard delivery pipe, hand shaking is inevitable, causing the bottom probe of the standard to fit the inner wall of the standard delivery pipe, or the relative shaking between the bottom probe of the standard and the water flow in the pipeline to be tested affects the measurement accuracy.
目前，在计量检定活动中或者实验中，人员对实验结果的要求比较高，但目前市场上的检测装置，人为操作下的标准器放置会产生很多不规范的问题，从而导致测量不精确或者参数与实际值不一致等问题。At present, in metrological verification activities or experiments, personnel have relatively high requirements for experimental results. However, the placement of standard instruments under manual operation in the current detection devices on the market will produce many non-standard problems, resulting in inaccurate measurements or inconsistencies between parameters and actual values.

It can also conveniently adjust the placement position of the standard device to reduce inaccurate measurement results caused by fluctuations of the standard device caused by human operation.
技术方案：本发明提供了一种管网液压检测装置，包括主体管、输送管以及安装在所述输送管管口处的输送机构，所述主体管的两端分别连接有能够与待检测管道的检测部两侧螺纹连接的活动连接头和固定连接头；所述输送管与所述主体管的中部连通，标准器通过所述输送机构输送至所述输送管内，且所述标准器的探头朝下位于所述主体管与所述输送管的衔接处。Technical solution: The present invention provides a pipe network hydraulic detection device, including a main pipe, a delivery pipe and a delivery mechanism installed at the pipe mouth of the delivery pipe, the two ends of the main pipe are respectively connected with a movable connector and a fixed connector that can be threadedly connected to the two sides of the detection part of the pipeline to be detected; the delivery pipe is connected to the middle part of the main pipe, the standard device is delivered to the delivery pipe through the delivery mechanism, and the probe of the standard device is located downward at the junction of the main pipe and the delivery pipe.
优选地，所述输送机构包括壳体、主动齿、从动齿、主动环形传输带、从动环形传输带以及若干主动传输带定位轴和从动传输带定位轴；所述壳体固定在所述输送管的管口处，所述主动齿的主动轴与所述从动齿的从动轴相互平行且转动连接在所述壳体内，所述主动齿与所述从动齿啮合；各所述主动传输带定位轴和各所述从动传输带定位轴分别沿所述输送管的内壁两侧上下依次平行安装；所述主动环形传送带的一端套在所述主动轴上，中部和末端分别套在各所述主动传输带定位轴上；所述从动形传送带的一端套在所述从动轴上，中部和末端分别套在各所述从动传输带定位轴上。需要将标准器传输到输送管内时，先将标准器的检测探头朝下从壳体上的标准器入口塞入主动环形传输带与从动环形传输带之间，驱动主动齿顺时针转动时，主动轴顺时针转动，带动主动环形传输带顺时针转动，进而各主动传输带定位轴顺时针转动；而从动齿与主动齿啮合，从而从动齿逆时针转动，从动轴逆时针转动，带动从动环形传输带逆时针转动，进而各从动传输带定位轴逆时针转动；主动传输带与从动传输带反方向旋转即能够实现将标准器从输送管的上方输送到下方；若输送的位置太低则可以通过反向方驱动主动齿将标准器上移调整位置；这样的输送机构能够使得标准器能够平稳地传送至并定位在输送管与主体管的衔接处进行测量，减少人为操作引起的标准器波动，在传送过程中也能有效避免标准器的检测探头触碰到输送管内壁引起的参数变化。Preferably, the conveying mechanism includes a shell, a driving tooth, a driven tooth, a driving annular conveyor belt, a driven annular conveyor belt and a plurality of driving conveyor belt positioning shafts and driven conveyor belt positioning shafts; the shell is fixed at the pipe mouth of the conveying pipe, the driving shaft of the driving tooth and the driven shaft of the driven tooth are parallel to each other and rotatably connected in the shell, and the driving tooth is meshed with the driven tooth; each of the driving conveyor belt positioning shafts and each of the driven conveyor belt positioning shafts are respectively installed in parallel along both sides of the inner wall of the conveying pipe up and down; one end of the driving annular conveyor belt is sleeved on the driving shaft, and the middle part and the end are respectively sleeved on each of the driving conveyor belt positioning shafts; one end of the driven annular conveyor belt is sleeved on the driven shaft, and the middle part and the end are respectively sleeved on each of the driven conveyor belt positioning shafts. When it is necessary to transfer the standard device into the conveying tube, first insert the detection probe of the standard device downward from the standard device entrance on the shell between the active annular conveyor belt and the driven annular conveyor belt. When the active tooth is driven to rotate clockwise, the active shaft rotates clockwise, driving the active annular conveyor belt to rotate clockwise, and then each active conveyor belt positioning shaft rotates clockwise; and the driven tooth is meshed with the active tooth, so that the driven tooth rotates counterclockwise, the driven shaft rotates counterclockwise, driving the driven annular conveyor belt to rotate counterclockwise, and then each driven conveyor belt positioning shaft rotates counterclockwise; the active conveyor belt and the driven conveyor belt rotate in opposite directions to realize the conveyance of the standard device from the top to the bottom of the conveying tube; if the conveying position is too low, the active tooth can be driven in the opposite direction to move the standard device up to adjust the position; such a conveying mechanism can enable the standard device to be smoothly conveyed to and positioned at the junction of the conveying tube and the main tube for measurement, reduce the fluctuation of the standard device caused by human operation, and effectively avoid the parameter changes caused by the detection probe of the standard device touching the inner wall of the conveying tube during the conveying process.
优选地，各所述主动传输带定位轴、各所述从动传输带定位轴、所述主动轴以及所述从动轴之间均相互平行设置。Preferably, each of the active transmission belt positioning axes, each of the driven transmission belt positioning axes, the active axis and the driven axis are arranged parallel to each other.
优选地，所述主动环形传输带与所述从动环形传输带之间的间距略小于待传输标准器的最小宽度。这样设计能够保证标准器能够被夹在主动环形传输带与从动环形传输带之间，实现稳定传输。Preferably, the spacing between the active annular conveyor belt and the driven annular conveyor belt is slightly smaller than the minimum width of the standard to be transmitted. Such a design can ensure that the standard can be clamped between the active annular conveyor belt and the driven annular conveyor belt to achieve stable transmission.
进一步地，在所述输送管内与所述主体管的衔接处还横向设置有定位轴，在所述定位轴上转动连接有接触杆，所述接触杆的一端转动连接在连杆的底端，所述连杆的顶端固定有限位块，所述限位块限位在所述壳体上开设的活动窗口内。因为在输送机构输送标准器时，标准器的底端探头何时到达输送管与主体管的衔接处，操作工人从外部很难判断，所以本发明中设计了上述结构，当标准器被输送机构输送至其探头接触到接触杆的一端时，接触杆中部绕定位轴旋转下降，接触杆的另一端则带着连杆上移，连杆顶部的限位块则会在活动窗口内上移，当限位块上移到活动窗口的最顶端时，限位块停止上移，此时刚好标准器的探头位于设定好的位置；上述结构的设计能够有效帮助操作工人将标准器精确地放入预设的位置。Furthermore, a positioning shaft is transversely arranged at the junction of the conveying tube and the main tube, and a contact rod is rotatably connected to the positioning shaft, one end of the contact rod is rotatably connected to the bottom end of the connecting rod, and a limit block is fixed at the top end of the connecting rod, and the limit block is limited in the movable window opened on the shell. Because when the conveying mechanism conveys the standard, it is difficult for the operator to judge from the outside when the bottom probe of the standard reaches the junction of the conveying tube and the main tube, so the present invention designs the above structure, when the standard is conveyed by the conveying mechanism until its probe contacts one end of the contact rod, the middle part of the contact rod rotates and descends around the positioning shaft, and the other end of the contact rod moves up with the connecting rod, and the limit block at the top of the connecting rod moves up in the movable window, and when the limit block moves up to the top of the movable window, the limit block stops moving up, and at this time, the probe of the standard is just at the set position; the design of the above structure can effectively help the operator to accurately put the standard into the preset position.
优选地，所述连杆位于所述输送管内且与所述输送管平行设置，所述连杆与所述接触杆垂直设置，所述接触杆与所述定位轴垂直设置。Preferably, the connecting rod is located in the conveying pipe and is arranged parallel to the conveying pipe, the connecting rod is arranged perpendicularly to the contact rod, and the contact rod is arranged perpendicularly to the positioning shaft.
优选地，所述定位轴的长度小于所述输送管的内径。这样设计后能够有效避免定位轴阻挡标准器顺利下移。Preferably, the length of the positioning shaft is smaller than the inner diameter of the conveying tube. This design can effectively prevent the positioning shaft from blocking the standard from moving downward smoothly.
优选地，所述接触杆的总长度小于所述输送管的内径。这样设计后能够保证接触杆能够被标准器的探头轻松下压绕定位轴旋转。Preferably, the total length of the contact rod is smaller than the inner diameter of the conveying tube. This design can ensure that the contact rod can be easily pressed down by the probe of the standard instrument to rotate around the positioning axis.
进一步地，所述的管网液压检测装置还包括驱动手柄，所述驱动手柄与所述主动齿的主动轴固定连接且位于所述壳体外部。驱动手柄用于驱动主动齿带动主动轴及主动环形传输带转动，进而带动从动齿、从动轴、从动环形传输带转动，进而实现对夹在主动环形传输带与从动环形传输带之间的标准器的传输。Furthermore, the pipe network hydraulic detection device further comprises a driving handle, which is fixedly connected to the driving shaft of the driving gear and is located outside the housing. The driving handle is used to drive the driving gear to drive the driving shaft and the driving annular transmission belt to rotate, thereby driving the driven gear, the driven shaft, and the driven annular transmission belt to rotate, thereby realizing the transmission of the standard device sandwiched between the driving annular transmission belt and the driven annular transmission belt.
进一步地，所述壳体的顶部安装有防尘盖，所述防尘盖与所述壳体的顶部开口通过滑槽滑动连接。防尘盖打开时，能够将标准器从壳体上部开口投入到主动环形传输带与从动环形传输带之间，进而实现对标准器的传送；在不进行检测时，将防尘盖关闭防止灰尘进入到输送管内。Furthermore, a dust cover is installed on the top of the shell, and the dust cover is slidably connected to the top opening of the shell through a slide groove. When the dust cover is opened, the standard can be put into the active annular conveyor belt and the driven annular conveyor belt from the upper opening of the shell, thereby realizing the transmission of the standard; when no detection is performed, the dust cover is closed to prevent dust from entering the conveying pipe.
工作原理：当需要对待测管道内的液体液压进行检测时，首先将检测部位预留的管道拆卸下来，将本水管检测装置的固定连接头与待检测管道的检测部一侧螺纹连接，然后将活动连接头与待检测管道的检测部另一侧螺纹连接，然后将标准器放在输送机构内，通过输送机构将标准器的检测探头朝下输送至检测探头到达主体管与输送管的衔接处停止输送，此处即为检测点。Working principle: When it is necessary to test the liquid hydraulic pressure in the pipeline to be tested, first remove the pipeline reserved for the detection part, thread the fixed connector of the water pipe detection device to one side of the detection part of the pipeline to be tested, and then thread the movable connector to the other side of the detection part of the pipeline to be tested, and then place the standard in the conveying mechanism, and convey the detection probe of the standard downward through the conveying mechanism until the detection probe reaches the connection between the main pipe and the conveying pipe and stops conveying. This is the detection point.
有益效果：本发明与现有技术相比，具有以下明显优点：Beneficial effects: Compared with the prior art, the present invention has the following obvious advantages:
通过输送机构的输送，使得标准器被平稳地传送至并定位在输送管与主体管的衔接处进行测量，减少人为操作引起的标准器波动，在传送过程中也能有效避免标准器的检测探头触碰到输送管内壁引起的参数变化。在整个检测过程中，标准器都不会晃动颤抖，能够更加准确地测量出待检测管道内的液压。通过输送机构舒总标准器，还能够灵活调节标准器的高低位置，减少工人手持标准器操作引起的误差和外界因素波动。Through the conveying mechanism, the standard instrument is smoothly conveyed to and positioned at the junction of the conveying pipe and the main pipe for measurement, reducing the fluctuation of the standard instrument caused by human operation, and effectively avoiding the parameter changes caused by the detection probe of the standard instrument touching the inner wall of the conveying pipe during the conveying process. During the entire detection process, the standard instrument will not shake or tremble, and can more accurately measure the hydraulic pressure in the pipeline to be tested. Through the conveying mechanism, the height of the standard instrument can also be flexibly adjusted to reduce the errors caused by workers holding the standard instrument and fluctuations of external factors.

具体实施方式DETAILED DESCRIPTION
下面结合附图和具体实施方式对本发明做进一步的说明。The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
本实施方式提供了一种管网液压检测装置，如图1至4所示，主要由主体管1、输送管2以及安装在输送管2管口处的输送机构组成，主体管1的两端分别连接有能够与待检测管道的检测部两侧螺纹连接的活动连接头3（该活动连接头3为市售的型号为ShBd的304不锈钢内外丝直通连接头，直接购买回来之后连接在主体管1的一端）和固定连接头4（该固定连接头4为市售的型号为304不锈钢水管的螺母移动转换活接内丝的连接头，直接购买回来之后连接在主体管1的另一端）；输送管2的底端与主体管1的中部连通，标准器通过输送机构输送至输送管2内，且标准器的探头朝下位于主体管1与输送管2的衔接处。The present embodiment provides a pipe network hydraulic detection device, as shown in Figures 1 to 4, which is mainly composed of a main pipe 1, a delivery pipe 2 and a delivery mechanism installed at the pipe mouth of the delivery pipe 2, and the two ends of the main pipe 1 are respectively connected with a movable connector 3 that can be threadedly connected to the two sides of the detection part of the pipeline to be detected (the movable connector 3 is a commercially available 304 stainless steel internal and external thread straight-through connector with model ShBd, which is directly purchased and connected to one end of the main pipe 1) and a fixed connector 4 (the fixed connector 4 is a commercially available 304 stainless steel water pipe nut movable conversion live internal thread connector, which is directly purchased and connected to the other end of the main pipe 1); the bottom end of the delivery pipe 2 is connected to the middle part of the main pipe 1, and the standard device is delivered to the delivery pipe 2 through the delivery mechanism, and the probe of the standard device is located downward at the junction of the main pipe 1 and the delivery pipe 2.
上述输送机构主要由壳体5、主动齿6、从动齿7、主动环形传输带8、从动环形传输带9以及若干主动传输带定位轴10和从动传输带定位轴11组成；壳体5固定在输送管2的管口处，主动齿6的主动轴12与从动齿7的从动13轴均与相互平行且转动连接在壳体5内，主动齿6与从动齿7啮合，驱动手柄16与主动齿6的主动轴12固定连接且位于壳体5外部；各主动传输带定位轴10和各从动传输带定位轴11分别沿输送管2的内壁两侧上下依次平行安装；主动环形传送带8的一端套在主动轴12上，中部和末端分别套在各主动传输带定位轴10上；从动形传送带9的一端套在从动轴13上，中部和末端分别套在各从动传输带定位轴11上。主动环形传输带8与从动环形传输带9之间的间距略小于待传输标准器的最小宽度。壳体5的顶部安装有防尘盖18，防尘盖18与壳体5的顶部开口通过滑槽19滑动连接。The above-mentioned conveying mechanism is mainly composed of a shell 5, a driving tooth 6, a driven tooth 7, a driving annular conveyor belt 8, a driven annular conveyor belt 9 and a plurality of driving conveyor belt positioning shafts 10 and driven conveyor belt positioning shafts 11; the shell 5 is fixed at the pipe mouth of the conveying pipe 2, the driving shaft 12 of the driving tooth 6 and the driven shaft 13 of the driven tooth 7 are parallel to each other and rotatably connected in the shell 5, the driving tooth 6 is meshed with the driven tooth 7, and the driving handle 16 is fixedly connected to the driving shaft 12 of the driving tooth 6 and is located outside the shell 5; each driving conveyor belt positioning shaft 10 and each driven conveyor belt positioning shaft 11 are respectively installed in parallel up and down along both sides of the inner wall of the conveying pipe 2; one end of the driving annular conveyor belt 8 is sleeved on the driving shaft 12, and the middle and the end are respectively sleeved on each driving conveyor belt positioning shaft 10; one end of the driven conveyor belt 9 is sleeved on the driven shaft 13, and the middle and the end are respectively sleeved on each driven conveyor belt positioning shaft 11. The spacing between the active annular conveyor belt 8 and the driven annular conveyor belt 9 is slightly smaller than the minimum width of the standard to be transmitted. A dust cover 18 is installed on the top of the housing 5, and the dust cover 18 is slidably connected to the top opening of the housing 5 through a slide slot 19.
本实施方式中的管网液压检测装置的工作原理如下：The working principle of the pipe network hydraulic pressure detection device in this embodiment is as follows:
需要将标准器传输到输送管2内进行测量时，先沿滑槽19打开防尘盖18，然后将标准器的检测探头朝下从壳体5上的标准器入口18塞入主动环形传输带8与从动环形传输带9之间，转动驱动手柄16驱动主动齿6顺时针转动时，主动轴12顺时针转动，带动主动环形传输带8顺时针转动，进而各主动传输带定位轴10顺时针转动；而从动齿7与主动齿6啮合，从而从动齿7逆时针转动，从动轴13逆时针转动，带动从动环形传输带9逆时针转动，进而各从动传输带定位轴11逆时针转动；主动环形传输带8与从动环形传输带9反方向旋转即能够实现将标准器从输送管2的管口输送到输送管2与主体管1的衔接处；若输送的位置太低则可以通过反向旋转驱动手柄16反向驱动主动齿6将标准器上移调整位置，直至标准器的检测探头刚好位于输送管2与主体管1的衔接处，此时能够准确检测到主体管1内液体的流量，又不会因为检测探头伸入到主体管1内过深影响液体流量，影响检测结果。When it is necessary to transfer the standard to the conveying pipe 2 for measurement, first open the dust cover 18 along the slide slot 19, and then insert the detection probe of the standard downward from the standard inlet 18 on the housing 5 between the active annular conveyor belt 8 and the driven annular conveyor belt 9. When the driving handle 16 is turned to drive the active gear 6 to rotate clockwise, the active shaft 12 rotates clockwise, driving the active annular conveyor belt 8 to rotate clockwise, and then each active conveyor belt positioning shaft 10 rotates clockwise; and the driven gear 7 is meshed with the active gear 6, so that the driven gear 7 rotates counterclockwise, the driven shaft 13 rotates counterclockwise, and drives the driven annular conveyor belt 9 to rotate counterclockwise. The active annular conveyor belt 8 and the driven annular conveyor belt 9 rotate in opposite directions, so that the standard device can be transported from the mouth of the conveying pipe 2 to the junction of the conveying pipe 2 and the main pipe 1; if the conveying position is too low, the driving gear 6 can be driven in the reverse direction by the reverse rotation of the driving handle 16 to move the standard device upward to adjust the position until the detection probe of the standard device is just located at the junction of the conveying pipe 2 and the main pipe 1. At this time, the flow rate of the liquid in the main pipe 1 can be accurately detected, and the liquid flow rate will not be affected by the detection probe extending too deeply into the main pipe 1, thereby affecting the detection result.
实施方式2Implementation Method 2
本实施方式为实施方式1的进一步改进，主要改进之处在于，在实施方式1中，在输送机构对标准器进行输送时，标准器的底端检测探头什么时间到达输送管2与主体管1的衔接处无法精确判断，检测探头伸入到主体管1内太深或太浅都会影响测量结果的精度。而本实施方式中，能够比较精确地判断检测探头什么时间到达输送管2与主体管1的衔接处。This embodiment is a further improvement of the embodiment 1, and the main improvement is that in the embodiment 1, when the conveying mechanism conveys the standard, it is impossible to accurately judge when the bottom detection probe of the standard reaches the connection between the conveying tube 2 and the main tube 1, and the detection probe extends too deep or too shallow into the main tube 1, which will affect the accuracy of the measurement result. In the embodiment, it is possible to more accurately judge when the detection probe reaches the connection between the conveying tube 2 and the main tube 1.
具体地说，本实施方式中的管网液压检测装置中，如图5至7，在输送管2内与主体管1的衔接处还横向固定有长度小于输送管2内径的定位轴20，在定位轴20上转动连接有长度小于输送管2内径的接触杆21，接触杆21的一端转动连接在与输送管2平行设置且垂直于定位轴20的连杆22的底端，连杆22的顶端固定有限位块23，限位块23限位在壳体5上开设的活动窗口24内。Specifically, in the pipeline hydraulic detection device in this embodiment, as shown in Figures 5 to 7, a positioning shaft 20 with a length less than the inner diameter of the conveying pipe 2 is also horizontally fixed at the connection between the conveying pipe 2 and the main pipe 1, and a contact rod 21 with a length less than the inner diameter of the conveying pipe 2 is rotatably connected to the positioning shaft 20. One end of the contact rod 21 is rotatably connected to the bottom end of a connecting rod 22 arranged parallel to the conveying pipe 2 and perpendicular to the positioning shaft 20. A limit block 23 is fixed to the top end of the connecting rod 22, and the limit block 23 is limited in a movable window 24 opened on the shell 5.
在输送机构将标准器从输送管2的管口向下输送时，当标准器的检测探头被输送至与接触杆21的一端接触时，接触杆21中部绕定位轴20旋转下降，接触杆21的另一端则带着连杆22上移，连杆22顶部的限位块23则会在活动窗口24内上移，当限位块23上移到活动窗口24的最顶端时，限位块23停止上移，此时刚好标准器的探头位于设定好的位置；上述结构的设计能够有效帮助操作工人将标准器精确地放入预设的位置。When the conveying mechanism conveys the standard downward from the mouth of the conveying pipe 2, when the detection probe of the standard is conveyed to contact one end of the contact rod 21, the middle part of the contact rod 21 rotates and descends around the positioning axis 20, and the other end of the contact rod 21 moves up with the connecting rod 22, and the limit block 23 at the top of the connecting rod 22 moves up in the movable window 24. When the limit block 23 moves up to the top of the movable window 24, the limit block 23 stops moving up, and the probe of the standard is just at the set position. The design of the above structure can effectively help the operator to accurately place the standard in the preset position.
除此之外，本实施方式与实施方式1完全相同，此处不做赘述。Apart from this, this embodiment is completely the same as Embodiment 1 and will not be described in detail here.
上述实施方式只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所做的等效变换或修饰，都应涵盖在本发明的保护范围之内。The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
