Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, and particularly relates to a coupling plum blossom pad replacement device for a large horizontal motor. Background Technique

[0002] In a hydropower station, different hoists need to be set according to the requirements of water conservancy and hydropower project layout, gate type, number of holes, operation, etc. For the working gates with functions such as flood control and drainage, fixed hydraulic hoists are used for operation; among them, an electric motor is required in the hydraulic transmission system of the hydraulic hoist to drive the oil pump to pressurize. In large hydropower projects, the hydraulic oil pump motor in the hydraulic transmission system is usually horizontal and has a large weight, reaching 1000 KG.

[0003] An elastic plum blossom pad is provided at the connection between the above-mentioned large horizontal motor and the oil pump. Due to the normal operation of the hoist, the elastic plum blossom pad is easily damaged under the influence of factors such as long-term vibration, impact, wear, aging, and quality environment. If it continues to operate, it may cause unstable transmission of the hoisting driving force, easily cause shaft fracture, and even more seriously lead to unit shutdown.

[0004] At present, there are two methods for replacing the elastic plum blossom pad, including prying it open with a crowbar or lifting it off with an electric hoist. For replacing the plum blossom pad of a lighter motor, a crowbar is usually used to pry the motor to separate the two half couplings and replace the plum blossom pad; for a heavier motor, a hoist is usually used to lift the motor away from the motor base, and then the motor is horizontally moved away from the oil pump by manpower or by using an electric hoist to separate the two half couplings and replace the plum blossom pad. The method using a crowbar not only consumes physical strength but also has a safety hazard of hurting people, with a relatively high safety risk; the method using a hoist requires a suitable lifting point. If there is no lifting point, a lifting point needs to be set by means such as building a scaffold. The process is complex, time-consuming and laborious, and there is a risk of deformation of the coupling and the motor shaft.

[0005] Based on this, a device for replacing the coupling plum blossom pad of a large horizontal motor is needed to help operators replace the plum blossom pad safely and quickly. Summary of the Utility Model
