Description

TECHNICAL FIELD

[0001] The utility model relates to water turbine generator brake carrying technical field, concretely relates to a kind of quick carrying device for water turbine generator brake. BACKGROUND

[0002] During the process of generator shutdown, when the speed is lower than a certain limit, the brake needs to be put into operation, and the mechanical brake is used to quickly reduce the speed of the generator rotor to zero to prevent the rotor from creeping for a long time due to its inertia, which damages the guide bearing and the main shaft. The water turbine generator brake (air brake) is generally installed below the generator rotor, and is powered by a low-pressure air system, including a brake chamber and a return chamber. The space is relatively small based on the following rack, and the return chamber of the brake is pressurized when the brake returns, and the brake chamber is not pressurized. A sealing ring is provided between the two chambers to separate the gas between the two chambers. During operation, brake air may leak into the chamber, which may reduce the speed of the generator. At this time, the brake needs to be removed and the internal seal needs to be replaced. In order to shorten the time required for removing the brake, the brake repair period is shortened.

[0003] However, the traditional disassembly method relies on manual carrying of the brake, which is often inefficient and has a high risk of brake falling off, resulting in prolonged unit repair period. At this time, a tool capable of quickly removing and safely carrying the brake is needed. In the traditional way, after removing the fixed connecting parts and bolts, the brake is tied with a sling on both sides, and two people drag the sling, while one person needs to adjust the displacement when the brake moves. This method often takes a lot of time to ensure construction safety and has a long construction period. During the work process, the brake may fall off, causing personal injury to the construction personnel. UTILITY MODEL CONTENTS

[0016] Specifically, the bearing mechanism 1 is used for bearing the brake, wherein the bearing mechanism 1 can adjust the height, that is, bearing the brake with different heights. When the brake located below the engine rotor needs to be repaired or removed, the bearing mechanism 1 is moved to below the brake, the height is adjusted until the lower end of the brake is abutted, at this time, the bolt fixedly connecting the brake and the engine is removed, so that the brake is completely separated from the engine rotor and placed on the upper end of the bearing mechanism 1, at this time, the height of the bearing mechanism 1 is adjusted, so that the height of the brake is lowered, and the bearing mechanism 1 is convenient for bearing the brake away from the engine rotor.

[0024] Specifically, the moving plate 231 and the moving guide rail 21 are both selected from heavy channel steel, which has the following advantages: 1. High strength: the heavy channel steel has high yield strength and tensile strength, and can bear a large load, suitable for the movement and transportation of heavy equipment; 2. Good wear resistance: the surface hardness of the channel steel is high, and the wear resistance is good, which can withstand long-term high-load operation without easy wear, prolonging the service life of the guide rail; 3. Good stability: the cross-sectional shape of the heavy channel steel has good structural stability, and is not easy to twist and deform, ensuring the straightness and precision of the moving guide rail 21; 4. Large carrying capacity: the channel steel has large cross-sectional size, which can provide larger contact area to disperse pressure and improve carrying capacity, suitable for heavy load occasions; 5. Easy to install and maintain: the shape of the heavy channel steel is regular, which is convenient for installation and fixation, and also convenient for inspection and maintenance; 6.
