Description

Technical Field

[0001] The utility model relates to a disassembly gripper for a brake wheel coupling of a bridge crane, belonging to the technical field of disassembly tools in the metallurgical industry. Background Art

[0002] The connection between the power input and output mechanisms of the operating mechanism of a bridge crane needs to be achieved through a coupling. The brake wheel coupling installed on the shafts of the motor, reducer, wheel set, etc. needs to be disassembled for inspection or repair. Due to limited space, the general three-claw puller cannot be used. The knocking disassembly method often causes damage to the brake wheel coupling, and even requires cutting and disassembling these couplings, resulting in waste of spare parts. Utility Model Content

[0003] The purpose of the utility model is to provide a bridge crane brake wheel coupling disassembly gripper, which can conveniently and quickly complete the disassembly of the bridge crane brake wheel coupling, avoid damage to the brake wheel coupling, and solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A bridge crane brake wheel coupling disassembly gripper comprises a pulling disc, a circular hole, an internal threaded body, a screw push rod, a connecting bolt, a brake wheel coupling, a motor output shaft and a motor. The brake wheel coupling is sleeved on the motor output shaft. The pulling disc is provided with a number of circular holes matching the connecting bolts in the circumferential direction. The pulling disc is connected to the brake wheel coupling through the connecting bolts. The center of the pulling disc is provided with an internal threaded body which is an integral structure with the pulling disc. The screw push rod is threadedly connected to the internal threaded body. One end of the screw push rod is pressed against the motor output shaft.

[0006] The internal thread of the internal thread body matches the external thread of the lead screw push rod, and the thickness of the internal thread body is greater than the thickness of the drawing disk.

[0007] The drawing disc is provided with a plurality of reinforcing ribs connected with the internal thread body.

[0008] The circular holes matched with the connecting bolts in the circumferential direction of the drawing disc are arranged in two inner and outer circles, and the pitch circle of each circular hole is the same as the pitch circle of the bolt holes on the brake wheel coupling.

[0009] The other end of the lead screw push rod is a rectangular structure matched with the electric wrench.

[0010] By adopting the utility model, when the lead screw push rod is screwed in by an electric wrench, a pulling force is generated on the brake wheel coupling under the action of the internal thread body, thereby pulling the brake wheel coupling out from the motor output shaft.

[0011] The beneficial effects of the utility model are: it can conveniently and quickly complete the disassembly of the brake wheel coupling of the bridge crane under limited space, avoid damage to the brake wheel coupling, and has a simple structure, easy operation and high efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.

[0017] Refer to the attached Figure 1-3 A bridge crane brake wheel coupling disassembly gripper comprises a pulling disc 1, a circular hole 3, an internal threaded body 4, a screw push rod 5, a connecting bolt 6, a brake wheel coupling 7, a motor output shaft 8 and a motor 9. The brake wheel coupling 7 is sleeved on the motor output shaft 8. The pulling disc 1 is provided with a plurality of circular holes 3 in the circumferential direction thereof which match the connecting bolts 6. The pulling disc 1 is connected to the brake wheel coupling 7 through the connecting bolts 6. The center of the pulling disc 1 is provided with an internal threaded body 4 which is an integral structure with the pulling disc 1. The screw push rod 5 is threadedly connected to the internal threaded body 4, and one end of the screw push rod 5 is pressed against the motor output shaft 8.

[0018] In this embodiment, refer to the attached Figure 1-3 The disassembly gripper includes a drawing disc 1, a reinforcing rib 2, a round hole 3, an internal threaded body 4, a screw push rod 5, a connecting bolt 6, a brake wheel coupling 7, a motor output shaft 8, and a motor 9, wherein the brake wheel coupling 7 is mounted on the motor output shaft 8.
