Description

Technical Field

[0001] The utility model relates to the technical field of plunger pump maintenance, in particular to an automatic gear alignment mechanism of a plunger pump maintenance device for a fracturing vehicle. Background Art

[0002] During the operation of the fracturing truck, the plunger pump needs to be replaced and maintained because the plunger head is worn during the reciprocating motion. In the event of a failure, the traditional method is to use a crowbar to manually separate the two ends of the plunger pump for inspection and maintenance. Therefore, the operation method is time-consuming and laborious. In the existing electric disc pump device, the driven gear is connected to the input shaft of the fracturing truck plunger pump reducer, and the driven gear is selectively meshed with the driving gear. In the event of a failure, the driving gear is driven to rotate to drive the driven gear to rotate, and then in the case of power failure, the input shaft of the fracturing truck plunger pump reducer is rotated to move the plunger pump forward or backward, which is convenient for maintenance personnel to replace the valve body. However, to achieve the above function, it is crucial that the driven gear and the driving gear are meshed with each other. If the driven gear and the driving gear are not meshed, it is impossible to rotate the input shaft of the fracturing truck plunger pump reducer in the case of power failure to move the plunger pump forward or backward.

[0003] In order to achieve the meshing of the driven gear and the driving gear, the prior art patent publication number CN212803559U discloses an automatic gear alignment mechanism of a fracturing vehicle plunger pump maintenance device. When the valve body needs to be replaced, under the action of the sliding drive mechanism, the driving gear connected to the driving device moves to the driven gear position and meshes with the driven gear. Then, under the action of the driving device, the driving gear rotates to drive the driven gear, and the rotation of the driven gear can further drive the rotation of the engine output shaft on the fracturing vehicle. Finally, the high-pressure plunger pump is extended or retracted at one end, so that the plunger pump head moves forward or backward, which is convenient for the inspection and maintenance of the fracturing vehicle plunger pump.

[0004] However, in the above manner, if the turntable motor and the shaking motor are damaged, it is not convenient to disassemble, repair or replace the turntable motor and the shaking motor. Utility Model Content
