本发明涉及开槽机的传动系统，尤其是一种用于水利工程上的开槽机的传动系统。The invention relates to a transmission system of a slotting machine, in particular to a transmission system of a slotting machine used in water conservancy projects.
背景技术Background technique
水利工程往往需要在岩层或水泥浇筑结构上通过开槽对坝体进行后期定位或加固，开槽机是对岩层或水泥浇筑结构进行开槽的关键设备。在现实生活中，开槽机的传动系统多采用平行轴齿轮副结构，齿轮箱中设有一主动轮与从动轮，主动轮与电机轴头相连，电机带动主动轮转动，从动轮上连接有传动轴，传动轴一端伸出齿轮箱，在传动轴伸出端设置刀具，对需要开槽的部位进行开槽。这种传动方式的开槽机存在的主要问题是：由于一次只能驱动一个钻头，不仅工作效率极其低下，影响水利工程的施工进度，而且由于只有一个钻头，使用中对同步下移的齿轮箱而言，稳定性也差，产生的震动惯性也大，极易损坏钻头。Water conservancy projects often need to position or reinforce the dam body by slotting on the rock formation or cement pouring structure. The slotting machine is the key equipment for slotting the rock formation or cement pouring structure. In real life, the transmission system of the slotting machine mostly adopts a parallel shaft gear pair structure. There is a driving wheel and a driven wheel in the gearbox. The driving wheel is connected to the shaft head of the motor. Shaft, one end of the transmission shaft protrudes from the gearbox, and a tool is set at the protruding end of the transmission shaft to slot the parts that need to be slotted. The main problem of the slotting machine with this transmission mode is: because only one drill bit can be driven at a time, not only the work efficiency is extremely low, which affects the construction progress of the water conservancy project, but also because there is only one drill bit, the gear box that moves down synchronously during use As far as the drill is concerned, the stability is also poor, and the vibration inertia generated is also large, which is very easy to damage the drill bit.

The drive shaft transmits power through the output bevel gear pair between them, and the lateral output shaft drives the lateral tool after passing through the box; the synchronous shaft and the drive shaft The axis angle of the shaft is 90 degrees. The driving shaft transmits power through the balanced bevel gear pair between them. The synchronous shafts of the left and right gearboxes pass through the box and are connected by a coupling to realize load-sharing synchronous operation.
本发明中：所述的驱动轴为空心轴。In the present invention: the drive shaft is a hollow shaft.
本发明中：驱动轴、同步轴、侧向输出轴与箱体的结合部由轴承支撑，并设有透盖。In the present invention: the combination of the drive shaft, the synchronous shaft, the lateral output shaft and the box body is supported by bearings, and a transparent cover is provided.
本发明中：左右齿轮箱的共用基座设在左右齿轮箱的上方，左右齿轮箱通过定位螺栓与共用基座连接。In the present invention: the shared base of the left and right gear boxes is arranged above the left and right gear boxes, and the left and right gear boxes are connected with the shared base through positioning bolts.
本发明的优点在于：由于齿轮箱采用液压马达驱动，具有较好的过载能力；由于齿轮箱为左右对称的组合齿轮箱，左右齿轮箱设有驱动轴和侧向输出轴，驱动轴由上至下贯穿箱体，驱动轴上端与液压马达输出端对接，下端驱动下方的刀具；侧向输出轴与驱动轴输入端的轴交角为80—85度之间，驱动轴通过它们之间的输出锥齿轮副传递动力，侧向输出轴穿越箱体后驱动侧向刀具这种结构可以同时提供四个作业点，实现一输入多输出，不仅可以提高工作效率，而且多点支撑还可以共同稳定齿轮箱，减小齿轮箱的震动惯性对刀具的影响。由于齿轮箱中还设有同步轴，同步轴与驱动轴的轴交角为90度，驱动轴通过它们之间的平衡锥齿轮副传递动力，左右齿轮箱的同步轴穿越箱体后由联轴器对接，较好的实现了均载同步运行。由于所述的驱动轴为空心轴，可以减轻齿轮箱的重量，采用螺伞齿多角度啮合，不仅使齿轮箱结构更加紧凑，同时改变了力的传递方向。由于左右齿轮箱的共用基座设在左右齿轮箱的上方，左右齿轮箱通过定位螺栓与共用基座连接使得左右齿轮箱在工作中随刀具上下位移时仍然保持良好的整体性；传动轴采用空心轴结构，可用于通冷却水，降低齿轮箱及刀具温度；螺伞齿的轴交角为82度，使输出轴和刀具受力小一些，提高其使用寿命；悬挂式支撑，便于安装与拆卸；两台齿轮箱之间采用联轴器连接，可实现开槽机的同步工作。The advantages of the present invention are: the gear box is driven by a hydraulic motor, so it has better overload capacity; because the gear box is a left-right symmetrical combined gear box, the left and right gear boxes are provided with drive shafts and lateral output shafts, and the drive shafts are from top to bottom. The bottom runs through the box, the upper end of the drive shaft is docked with the output end of the hydraulic motor, and the lower end drives the tool below; the angle between the lateral output shaft and the input end of the drive shaft is between 80-85 degrees, and the drive shaft passes through the output bevel gear between them The power is transmitted by the pair, and the lateral output shaft drives the lateral cutter after passing through the box. This structure can provide four operating points at the same time, realizing one input and multiple outputs, which can not only improve work efficiency, but also stabilize the gearbox with multiple points of support. Reduce the impact of the vibration inertia of the gearbox on the tool. Since there is also a synchronous shaft in the gearbox, the shaft angle between the synchronous shaft and the drive shaft is 90 degrees, and the drive shaft transmits power through the balanced bevel gear pair between them. Docking, better realize load sharing and synchronous operation. Since the drive shaft is a hollow shaft, the weight of the gearbox can be reduced, and the multi-angle engagement of the spiral bevel teeth not only makes the structure of the gearbox more compact, but also changes the direction of force transmission. Since the common base of the left and right gear boxes is set above the left and right gear boxes, the left and right gear boxes are connected with the common base through positioning bolts so that the left and right gear boxes still maintain good integrity when they move up and down with the tool during work; the transmission shaft is hollow The shaft structure can be used to pass cooling water to reduce the temperature of the gearbox and the tool; the shaft angle of the spiral bevel gear is 82 degrees, which reduces the force on the output shaft and the tool and improves its service life; the suspension support is easy to install and disassemble; The two gearboxes are connected by a coupling, which can realize the synchronous work of the slotting machine.
