Description

Technical Field

[0001] The utility model relates to the field of motor - generators, in particular to a special barring tool for motor - generators. Background Technique

[0002] A motor - generator is an electrical equipment that can be used both as a generator and as a motor, and is mainly used in pumped - storage power stations. Motor - generators are divided into horizontal and vertical types according to the position of the main shaft. Vertical motors can be divided into two major categories: suspended type and umbrella type according to the position of the thrust bearing. The thrust bearing installed above the rotor is called the suspended type; the one installed below the rotor is called the umbrella type.

[0003] The barring inspection of a motor - generator is an important item in the maintenance of pumped - storage units. Since the weight of the rotating components of the motor - generator reaches more than 300T, if the rotating components are directly pushed by workers to achieve barring, it is not only time - consuming and laborious, but also there is a safety risk of personnel injury. Therefore, we propose a special barring tool for motor - generators to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a special barring tool for motor - generators to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A special barring tool for motor - generators includes two semi - circular central bodies. On the mutually - remote side surfaces of the two semi - circular central bodies, two wheel arms are fixedly connected respectively. On the mutually - close side surfaces of the two semi - circular central bodies, two groups of through - holes are opened. Four stud bolts are commonly arranged outside the two semi - circular central bodies. The front ends of the two groups of stud bolts sequentially penetrate through the two groups of through - holes and extend to the outside of the two groups of through - holes. Locking nuts are threadedly connected to the outer surfaces of the two groups of stud bolts.

[0007] In a further embodiment, threaded holes are opened on the outer surfaces of the two semi - circular central bodies, and fixing bolts are arranged outside the two semi - circular central bodies, and the outer surface of the fixing bolt is adapted to the inner wall of the threaded hole.

[0008] In a further embodiment, two fixing pads are fixedly connected to the mutually - close side surfaces of the two semi - circular central bodies respectively, and anti - slip sheaths are fixedly connected to the outer surfaces of the four wheel arms.

[0009] In a further embodiment, a plurality of reinforcing pieces are fixedly connected to the outer surfaces of the two semi - circular central bodies, and an operation plate is fixedly connected to the outer surface of one of the semi - circular central bodies.

[0010] In a further embodiment, gaskets are sleeved on the outer surfaces of the four clamping bolts, and the number of gaskets is at least four.

[0011] In a further embodiment, the overall length between the two wheel arms is 260 cm, and the overall length between the two semi-circular central bodies is 150 cm.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the cooperation of the clamping bolts and the locking nuts, the device can lock and fix the two semi-circular central bodies on the surface of the large shaft of the generator motor. Then, by installing the two semi-circular central bodies on the surface of the large shaft and cooperating with the four wheel arms, the large shaft can be driven to move by the two semi-circular central bodies to achieve the purpose of barring the generator motor. Thus, the problems existing in the maintenance operation in the background art can be overcome, and the barring work of the generator motor can be completed efficiently and safely.
