Problems solved by technology
[0003] Because the weight of the magnetic poles of large-scale hydro-generators ranges from several hundred kilograms to several thousand kilograms, the magnetic poles cannot be hung on the rotor bracket manually, and the magnetic poles must be lifted and hung on the rotor bracket with the help of cranes and lifting tools. At present, , when mounting the magnetic pole, there is no special magnetic pole mounting tool. The staff will put one end of the lifting rope directly on the pole body of the magnetic pole coil, and the other end will use the crane to lift the hook to carry out the magnetic pole mounting, which will easily cause damage to the magnetic pole coil. Stretch deformation, and cause cracks between the turns of the magnetic pole coil, resulting in unqualified magnetic poles that need to be repaired, and it is labor-intensive, time-consuming, and inefficient

Embodiment Construction
[0017] In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0018] see Figure 1 to Figure 3 ,
[0019] A hanger for mounting the rotor magnetic poles of a large hydroelectric generator, comprising two parallel beams (1, 2), with support beams 3 evenly distributed and fixed between the bottoms of the two beams, and support beams 3 at one end The vertical plate 4 is fixed on the top, and the lifting plate 5 is fixed on the outside of the vertical plate. According to the force analysis, when the lifting plate is fixed on the middle position of the vertical plate, the bearing capacity of the lifting plate is relatively large, and the entire lifting plate The force is relatively uniform. The hoisting plate 5 is provided with the hoisting hole 5-1 of wearing a hoisting rope, and the outer symmetry of...

The invention relates to a large-scale hydraulic generator rotor magnetic pole hanging and lifting rack which is characterized by comprising two parallel cross beams, wherein support beams are evenly distributed and fixedly arranged between the bottoms of the two cross beams; a vertical plate is fixed on the support beams at one end part; the outer side of the vertical plate is fixed with a lifting plate; the lifting plate is provided with a lifting hole through which a lifting rope can penetrate; and the outer side of the two cross beams is symmetrically provided with the lifting plate. In the lifting process, the magnetic pole is put on the lifting rack, four lifting hooks on the outer side of the cross beams respectively hook the damping rings of the magnetic pole, one end of the lifting rope penetrates through the lifting hole of the lifting plate, and the other end of the lifting rope is hung on the lifting hooks of an overhead crane, so that the magnetic pole can be vertically erected and hung to the rotor spider. Thus, the invention has the advantages of simple operation, high speed, high safety, time saving, labor saving, high efficiency and the like, and can not damage the magnetic pole coil.
Description
technical field [0001] The utility model belongs to the technical field of large hydroelectric generators, in particular to a hanger for mounting rotor magnetic poles of large hydroelectric generators. Background technique [0002] The rotor is an important part of a large hydroelectric generator. It is assembled by hanging the magnetic poles on the rotor bracket. The magnetic pole is an important part. It consists of two parts: the magnetic pole core and the magnetic pole coil, and the magnetic pole The iron core is composed of several thin steel plates threaded together by screws to form a whole. The magnetic pole coil is made of copper strips to form a multi-turn oblong magnetic pole coil, and insulating paper is added between the layers of each turn. Press the magnetic pole coil and insulating paper into a whole, and then put the magnetic pole coil on the outside of the magnetic pole core to form a magnetic pole. [0003] Because the weight of the magnetic poles of larg...
