Description

Technical Field

[0001] The utility model relates to the technical field of gear box oil pump motor tools, in particular to a maintenance auxiliary tool. Background Art

[0002] The oil pump motor is one of many types of motors. The power output end of the oil pump motor is connected to the driving wheel of the oil pump. The oil in the oil tank is pumped into the gearbox by the rotation of the driving wheel and the driven wheel in the oil pump. When the output end of the oil pump motor is assembled with the driving wheel of the oil pump, the axis of the two is easy to deviate, which will cause radial movement of the oil pump when it rotates. In addition, the cooperation between the rotor core, the bearing and the shaft mainly relies on the support force generated by the tight fit between the inner ring and the shaft and the support force brought by the ball bearing.

[0003] Under the existing working conditions, the labor intensity of operators when replacing the gearbox oil pump motor is high. The gearbox oil pump motor is heavy and operators need to lift it manually during replacement. It takes at least 3 people to complete the replacement, and operators may be pinched or squeezed during replacement.

[0004] To this end, a maintenance auxiliary tool is designed to provide another technical solution to the above technical problem. Utility Model Content

[0011] As a preferred embodiment of the maintenance auxiliary tool provided by the utility model, the anti-rotation mechanism includes a fixed sleeve, a limit plate, a lifting block and a compression spring. The top end of the outer side of the assembly positioning sleeve is slidably connected with the fixed sleeve, and the interiors of the two ends of the top of the fixed sleeve are slidably connected with the lifting blocks. A compression spring is fixed inside the fixed sleeve and at the bottom of the lifting block. The tops of the two lifting blocks are fixed with limit plates, and the limit plates are slidably connected to the anti-rotation block.

[0012] As a preferred implementation of the maintenance auxiliary tool provided by the utility model, an assembly groove is provided inside the bottom end of the fixing sleeve, and the assembly groove is slidably connected to the reinforcing rib.

[0017] The utility model provides an auxiliary maintenance tool. Through the cooperation of a fixing frame, an assembly positioning sleeve, a support rod, a reinforcing rod and a fixing sleeve, the fixing frame can be installed at the gear box lifting lug for fixing. After the support rod is assembled on the top of the assembly positioning sleeve, the manual hoist assembled at the lifting ring position drives the gear box oil pump motor to adjust the installation and removal position, thereby assisting the use of existing equipment.

[0018] Through the cooperation of the fixed sleeve, the stop block and the limit plate, when the support rod does not need to rotate in a plane, the stop block can be located on the inner side of the stop groove, and the rotation of the support rod can be limited by limiting the position of the stop block by the limit plate. When the support rod needs to rotate, the limit plate is pressed down, so that the limit plate drives the compression of the compression spring to descend through the lifting block, thereby allowing the stop block to disengage from the stop groove and allow the support rod to rotate.

[0036] Embodiment 2

[0037] Reference Figure 3-Figure 7, a maintenance auxiliary tool, a stop block 10 is evenly arranged on the outside of the support rod 6 and on the top of the assembly positioning sleeve 4, and a fixing bolt 11 is slidably connected inside the stop block 10, and the fixing bolt 11 is threadedly connected to the support rod 6, so that the stop block 10 is fixed to the outside of the support rod 6 through the connection between the fixing bolt 11 and the support rod 6, and a stop mechanism for limiting the rotation of the stop block 10 is installed on the top of the assembly positioning sleeve 4. The stop mechanism includes a fixing sleeve 9, a limit plate 12, a lifting block 13 and a compression spring 15, and a fixing sleeve 9 is slidably connected to the top of the outer side of the assembly positioning sleeve 4, and an assembly groove 14 is opened inside the bottom end of the fixing sleeve 9, and the assembly groove 14 is slidably connected to the reinforcing rib 5, so that the fixing sleeve 9 cannot rotate on the outer side of the assembly positioning sleeve 4 through the cooperation of the assembly groove 14 and the reinforcing rib 5;

[0038] The interior of both ends of the top of the fixed sleeve 9 is slidably connected with a lifting block 13, and the lifting block 13 is located between two adjacent assembly grooves 14. A compression spring 15 is fixed inside the fixed sleeve 9 and at the bottom of the lifting block 13, so that the descent of the lifting block 13 drives the compression spring 15 to be compressed; a limit plate 12 is fixed on the top of the two lifting blocks 13, and the limit plate 12 is slidably connected with the anti-rotation block 10, so that the anti-rotation block 10 cannot rotate in a plane when it is located inside the limit plate 12, thereby limiting the rotation of the support rod 6 inside the assembly positioning sleeve 4;

[0039] The top of the limit plate 12 is evenly provided with anti-rotation grooves 16, and the limit plate 12 and the anti-rotation block 10 are slidably connected through the anti-rotation grooves 16, so that the anti-rotation block 10 can be located in different anti-rotation grooves 16 to limit the rotation. The top of the limit plate 12 and the two ends of the anti-rotation groove 16 are provided with assembly bevels 17, so that when the limit plate 12 rises and the anti-rotation block 10 enters the anti-rotation groove 16, the assembly bevels 17 can prevent it from getting stuck.

[0040] The use process of the maintenance auxiliary tool provided by the utility model is as follows: when it is necessary to replace the gear box oil pump motor again, to limit the plane rotation of the support rod 6 inside the top of the assembly positioning sleeve 4, first, before the support rod 6 and the assembly positioning sleeve 4 are installed, the anti-rotation block 10 is fixed on the outside of the support rod 6 by the fixing bolt 11, and at the same time, the fixing sleeve 9 is assembled inside the top of the assembly positioning sleeve 4, and is connected with the slidable rib 5 through the assembly groove 14, so that the fixing sleeve 9 can only be lifted and slid outside the top of the assembly positioning sleeve 4 but cannot be rotated. Then, when the support rod 6 is installed inside the assembly positioning sleeve 4, the anti-rotation block 10 is allowed to enter through the assembly inclined surface 17 The support rod 6 is inside the anti-rotation groove 16 of the sliding connection. At this time, the support rod 6 cannot rotate. When the support rod 6 needs to be rotated in a plane to adjust the angle, the limit plate 12 is pressed down, so that the limit plate 12 descends and drives the lifting block 13 to descend, and the descent of the lifting block 13 compresses the compression spring 15. At the same time, the descent of the limit plate 12 allows the anti-rotation block 10 to disengage from the anti-rotation groove 16 of the sliding connection, thereby allowing the anti-rotation groove 16 to rotate. When it is necessary to restore the rotation restriction on the support rod 6, the pressure on the limit plate 12 is released, and the limit plate 12 is reset by the rebound after being compressed by the compression spring 15, thereby allowing the anti-rotation groove 16 on the limit plate 12 to be located on the outside of the anti-rotation block 10 of the sliding connection.
