Problems solved by technology
At the same time, due to design and process considerations, the gap between the stator and the rotor is very small, and the two must not collide during the entire core-piercing process to cause damage to the insulation layer, making the entire core-piercing work very difficult
[0003] In addition, in conventional construction, cranes, spreaders, and chain rewinding are mostly used. It is necessary to hang the rewinding chain multiple times and perform at least three slow hook operations to complete the core piercing operation. At the same time, hydraulic cranes are required to cooperate with the construction. The procedure is cumbersome and labor-intensive. big, expensive

The present invention discloses a motor core-through device which comprises a plurality of traveling elevating devices which sleeve rotor dummy shafts and tracks which allow the traveling elevating devices to move. Each of the traveling elevating devices comprises a base, a walking wheel installed on the base and is used for driving the base to move, an elevating device which is fixed to the base, a bracket which is fixed to the top end of the elevating device, a support seat fixed to the bracket, and a pressing cover which is removably connected to the support seat. A mounting hole which allows the dummy shafts to go through is formed by the pressing cover and the support seat. Two sides of the stator are equipped with the tracks, and the walking wheels of the traveling elevating devices are installed on the tracks. The invention provides the motor core-through device, the construction mode of multiple times of hanging chain blocks, at least three times of slow hook operations and hydraulic crane cooperation in the a traditional method is changed, and by using the motor core-through device, the core-through operation can be in place through only one time of hanging.
Description
technical field [0001] The invention relates to the technical field of motor production, in particular to a motor core threading device and a threading method thereof. Background technique [0002] Due to their large size and heavy weight, for the convenience of transportation and construction, large motors are usually divided into stators and rotors and delivered separately, and core piercing operations need to be carried out on site. At the same time, due to design and process considerations, the gap between the stator and the rotor is very small, and the two must not collide during the entire core-piercing process to cause damage to the insulation layer, making the entire core-piercing work very difficult. [0003] In addition, in conventional construction, cranes, spreaders, and chain rewinding are mostly used. It is necessary to hang the rewinding chain multiple times and perform at least three slow hook operations to complete the core piercing operation. At the same ti...
