Embodiment Construction
[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0027] Please also refer to figure 1 and figure 2 Now, the device and method for drawing through the rotor 6 of the large motor provided by the present invention will be described. The large motor rotor 6 pull-through device includes a main balance beam body 1, a hoisting unit arranged on the top of the main balance beam body 1 for connecting the main balance beam body 1 with the hoisting device, and a hoisting unit whose end is connected below the main balance beam body 1. The first connecting rope 31 and the second connecting rope 32 whose end is connected...

The invention provides a large motor rotor drawing and penetrating device and method, and belongs to the technical field of motor maintenance, and the large motor rotor drawing and penetrating device comprises a main balance beam body, a hoisting unit, a first connecting rope, a second connecting rope and an extension connecting rod. According to the large motor rotor drawing and penetrating device and method provided by the invention, the extension connecting rod penetrates through the mounting hole in the motor stator, the end part of the extension connecting rod is fixedly connected to one end part of the motor rotor, and then the first connecting rope is connected to the end part of the extension connecting rod, and the second connecting rope is connected to the end part of the motor rotor; the main balance beam body is connected with the motor rotor and the extension connecting rod, and finally the motor rotor is pulled through the hoisting device. According to the utility model, through the supporting cooperation of the main balance beam body and the extension connecting rod, the motor rotor can be drawn and penetrated only by using one hoisting device, the occupied field area and the number of personnel in the motor maintenance process are reduced, the drawing and penetrating efficiency of the motor rotor is improved, and the motor maintenance speed is improved.
Description
technical field [0001] The invention belongs to the technical field of motor maintenance, and more particularly relates to a large motor rotor pull-through device and a pull-through method. Background technique [0002] In the process of motor repair, it is usually necessary to separate the stator and rotor. When the rotor is disassembled and installed, it involves the pull-through of the rotor. The pull-through refers to the process of removing and installing the motor rotor from the motor casing. Among them, the small motor can be pulled through the rotor of the motor by manpower or a hoisting frame, but when the size of the motor is large, there will be a problem of low pull-through efficiency when the rotor of the motor is pulled through. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a device and method for pulling through the rotor of a large motor, which aims to solve the problem of low efficiency when the rotor of the motor is ...
