Specifically, the positioning sleeve of the utility model has the following functions: when the shaft pulling device is erected, the shaft pulling device and the pin shaft are concentric, and the pin shaft cannot be abutted against the shaft pulling device during shaft pulling operation. When the mining truck suspension hollow pin shaft splitting device is actually used, firstly, the positioning sleeve is installed in the shaft pulling device to form a shaft pulling device for standby; then the accessories such as the bolt and the like for fixing the pin shaft are disassembled; then the pull rod is arranged in the positioning sleeve, the threaded end on the pull rod penetrates out of the positioning sleeve along the axial direction of the pin shaft, the threaded part extends out of the opposite side, and a nut is connected to the threaded part; finally, taking support protection measures to prevent the shaft pulling device (shaft pulling device) from falling; and starting the shaft pulling device to pull the pin shaft clamped in the bearing seat (because the pin shaft bears the rolling and impact loads for a long time, the part bearing the load is sunken, the edge is raised, the local deformation of the pin shaft is caused, and the pin shaft is difficult to disassemble, so that the pulling device is used for pulling and disassembling the pin shaft), and screwing down the nut after pulling to complete the disassembly of the suspension hollow shaft of the mining automobile.
Furthermore, the shaft pulling device is a hollow jack; the inner diameter of the central hole of the hollow jack is larger than the outer diameter of the pin shaft.
Further, the inner diameter of the central hole of the hollow jack is not less than 80 mm.

Specifically, since the outer diameter of the cylindrical main body is smaller than the inner diameter of the central hole of the hollow jack, the main body (i.e., the positioning sleeve) can move freely in the hollow jack (the shaft pulling device); because the outer diameter of the baffle ring is larger than the inner diameter of the central hole of the hollow jack, after the positioning sleeve is installed in the hollow jack, the baffle ring can abut against the end part of the central hole, the baffle ring is used as an acting point to drive the positioning sleeve to move after the hollow jack is started, the positioning sleeve drives the pull rod to move, and the pull rod pulls the pin shaft. Specifically, the through hole is arranged at the center of the closed part; after the pull rod is inserted into the positioning sleeve, the step arranged on the pull rod is blocked by the closed bottom of the main body, so that the threaded end on the pull rod extends out of the through hole in the center of the bottom of the main body, and the step abuts against the bottom of the main body (as shown in fig. 5).
Furthermore, the main body is also provided with an adjusting hole; the mining truck suspension hollow pin shaft splitting device further comprises a bolt; the bolt is inserted into the adjusting hole in a penetrating mode, and one end of the bolt abuts against the central hole of the hollow jack. When the hollow jack is operated and the pin shaft is pulled out of the bearing seat through the matching of the positioning sleeve and the pull rod, if the stroke of the hollow jack is insufficient, the pin shaft cannot be pulled out at one time, and the hollow jack can be operated to retract and reset; then, the positioning sleeve (namely the main body) is pulled out to expose the adjusting hole formed in the main body, the bolt is inserted into the adjusting hole of the positioning sleeve, the hollow jack is operated continuously to pull the shaft by taking the bolt as a supporting point until the pin shaft is pulled out and detached; and then the nut is detached, and the detachment is finished.
