Description

Technical Field

[0001] The invention relates to a quick disassembly tool and method for an elastic column pin of a motor coupling, and belongs to the field of maintenance of a motor coupling of a ship lock, and the like. Background Art

[0002] The ship lock miter gate hoist consists of a four-link mechanism, a speed change, a control system and a motor. The motor drives the horizontal reduction box, the vertical reduction box and the open gear to drive the crank to rotate to complete the opening and closing of the miter gate. Among them, the motor and the horizontal reduction box transmit torque through the elastic sleeve pin coupling. The elastic sleeve pin coupling is locked by the elastic sleeve pin group. Each pin is equipped with four nylon elastic rings. The elasticity of the ring is used to compensate for the relative displacement of the two shafts, transmit torque, and mitigate impact and absorb vibration.

[0003] The pin is installed in the coupling. The conical surface on the pin and the conical surface in the coupling hole produce an interference fit during daily operation, which makes it difficult to disassemble during the later maintenance process. The traditional disassembly method is to use a hammer to knock the end face of the elastic pin and the nut, but due to the narrow working space and the tight fit of the elastic pin, the pin thread and the nut are easily damaged during the disassembly process. Therefore, a set of motor coupling elastic pin quick disassembly tooling is designed to ensure safe and efficient maintenance work. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a quick disassembly tool and method for the elastic pin of a motor coupling, which can be used for the quick disassembly of the pin during the maintenance of the coupling, thereby improving its disassembly efficiency; effectively preventing damage to the elastic pin and the nut, shortening the maintenance time, and having practical significance for the maintenance of the lock.

[0007] The oil cylinder mounting plate is processed with waist-shaped bolt holes arranged in parallel, and the oil cylinder is fixedly mounted on the oil cylinder mounting plate by a bolt assembly passing through the waist-shaped bolt holes.

A chain connecting plane is processed on the connecting column. A pin hole is processed on the chain connecting plane. The end of the first chain or the second chain is hingedly connected to the connecting column through a pin shaft.

[0011] The oil cylinder is connected with the manual pump through a hydraulic oil pipe, and the piston rod of the oil cylinder is used to face the elastic pin of the coupling.
