Dismounting method, mounting method and dismounting and mounting device for hydroelectric gate wheel shaft sleeves

Abstract

The invention discloses a dismounting method, a mounting method and a dismounting and mounting device for hydroelectric gate wheel shaft sleeves. The dismounting and mounting device comprises a supporting base, two supporting rods, a crossbeam, a jack, a pushing cylinder and a plurality of spacer plates. The dismounting method mainly utilizes the dismounting and mounting device, and comprises thesteps that the dismounting and mounting device is first placed at an even position, a wheel, the used shaft sleeve of which needs to be dismounted, is then placed on the supporting base, the pushing cylinder is vertically put upon the used shaft sleeve of the wheel, the plurality of spacer plates are then placed upon the pushing cylinder, the jack is mounted on the spacer plates, and finally, pressure is applied by the jack to press the used shaft sleeve out of the wheel. The mounting method also mainly utilizes the dismounting and mounting device, and comprises the steps that the dismountingand mounting device is first placed at an even position, a wheel into which a new shaft sleeve needs to be mounted is then placed on the supporting base, the new shaft sleeve is placed on a shaft holeof the wheel, the plurality of spacer plates are then placed upon the new shaft sleeve, the jack is mounted on the spacer plates, and finally, pressure is applied by the jack to press the new shaft sleeve into the wheel.

Description

technical field [0001] Embodiments of the present invention relate to the construction of hydropower gate components, and in particular, to a method for dismounting a wheel shaft sleeve of a hydropower gate, an installation method and a disassembly device. Background technique [0002] The gate is an important water retaining and flood discharge equipment for hydropower plants. The gate wheel is a key part of the gate supporting and running, which is crucial to the safe and normal operation of the gate. Once the wheel is jammed or damaged, it will seriously endanger the safety of the gate and related hydraulic structures. After the gate wheel has been in operation for a long time, the wheel bushing will be rusted, worn or aged and swelled, and the wheel will be jammed and even unable to rotate normally, which will eventually cause excessive friction during the opening and closing operation of the gate, which will damage the gate body, opening and closing. Closed equipment an...

Problems solved by technology

[0003] At present, the disassembly and assembly of the wheel bushings of hydropower gates is the first difficulty in the entire maintenance project, especially for large wheels. Since there is no special disassembly device on site, the usual method of disassembly is manual beating directly on site, resulting in slow maintenance progress , the efficiency is low, and it is difficult to control the quality of disassembly and assembly due to manual direct beating. Often due to poor control, the new bushing will be damaged and deformed during press-fitting, and the installation quality cannot meet the technical standards, which greatly affects the use of the bushing life
