Wherein, second steel sheet 4 fixes transformer bottom channel-section steel on second steel sheet 4 through second bolt 43, and four structures altogether of both sides form complete bearing structure, enough support the transformer, and the condition that can not appear squinting takes place, and second steel sheet 4 is used for fixed second bolt 43 and bearing 3, and second steel sheet 4 is in vertical state all the time, and second steel sheet 4 and transformer bottom avris tightly laminate.
Wherein, the joint of the first steel plate 2 and the first bolt 41 is provided with a moving notch matched with the rod body of the first bolt 41, when the first steel plate 2 and the second steel plate 4 are pressed by the first bolt 41, the first bolt 41 moves along the moving notch until the first steel plate 2 and the second steel plate 4 are tightly jointed, the first steel plate 2 is used for fixing the land wheel 23 and the bearing 3, when the lifting work is carried out, the land wheel 23 moves inwards along the offset direction until the first steel plate 2 and the second steel plate 4 are jointed, the offset is finished, the nut 42 is welded with the second steel plate 4, the actual operation can be more convenient in the welding state, one end of the notch of the first bolt 41 penetrates through the first steel plate 2, the first bolt 41 is connected with the first steel plate 2 and the second steel plate 4, when the lifting work is carried out, the first steel plate 2 and the second steel plate 4 are tightly clamped together by the first bolt 41 and the nut 42, at this time, the lifting work is completed, and the nut 42 and the first bolt 41 bear the pressure given to the second steel plate 4 by the transformer.
The transverse plate 21 and the connecting plate 22 are combined to form a ladder-shaped supporting structure, the carrying caster body 1 is supported by the combined structure of the transverse plate 21 and the connecting plate 22 to integrally work, pressure given by the transformer and transmitted to the nut 42 and the first bolt 41 passes through the first steel plate 2, the pressure is transmitted to the transverse plate 21 and the connecting plate 22 by the first steel plate 2, and the whole pressure is borne by the ground wheel at the bottom and the connecting structure of the ground wheel.
Wherein, four land wheels 23 are divided into two groups, two directional wheels are one group, two universal wheels are one group, four carrying caster main bodies 1 are distributed at two sides of the transformer, two are arranged at each side, the arrangement of each side is consistent with the grouping of the land wheels 23, the weight transmitted by the transformer can be uniformly and stably borne, the condition that a certain part is unevenly stressed can not occur, the four carrying caster main bodies 1 are fixedly connected with the transformer through second bolts 43 and second steel plates 4, the second bolts 43 are connected with channel steel at the bottom of the transformer, the second steel plates 4 can be always tightly attached to the side of the bottom of the transformer in the working process, when the carrying-up work is carried out, the carrying caster main bodies 1 at different sides can not carry out a plurality of carrying-up operations at the same time, the carrying caster main bodies 1 at the same side can simultaneously work, when the carrying-up work of the carrying caster main bodies 1, the whole can carry out a, if the carrying caster main body 1 of different sides lifts up the during operation simultaneously, can shift to two reverse directions, the skew position at this moment can appear the conflict, can't carry out actual work, and the homonymy then can carry out simultaneous working, and homonymy during operation, the skew position is the same, and control overall balance can carry out simultaneous working.
The bearing 3 is sleeved with the first steel plate 2 and the second steel plate 4, the length of the first steel plate 2 is longer than that of the second steel plate 4, when the lifting operation is performed, the difference value between the second steel plate 4 and the first steel plate 2 is the height of the transformer when the transformer is lifted, the difference value is also matched with the displacement length of the first bolt 41 and the offset angle of the first steel plate 2 and is a mutually-related fixed value, and the upper end of the second steel plate 4 is rotatably connected with the bearing 3 through a welded transverse metal block.
The working principle is as follows: first, the first bolt 41 is adjusted so that the included angle between the first steel plate 2 and the second steel plate 4 is maximized. Then, the second steel plate 4 is fixed to the transformer bottom channel using the second bolt 43, and the second bolt 43 is screwed firmly. Four trundles are arranged at four corners of the transformer in the same mode, wherein one group of the trundles is 2 land wheels which are universal wheels, and the other group of the trundles is two fixed land wheels. After the second bolts 43 installed on the four land wheels are screwed firmly, the first bolts 41 of the 2 directional land wheels are adjusted and screwed slowly, so that the included angle between the first steel plate 2 and the second steel plate 4 is gradually reduced. Because second steel sheet 4 length is greater than the length of first steel sheet 2, and the transformer is fixed on second steel sheet 4 for first bolt 41 is at the in-process of screwing up, along with the reduction of the contained angle between first steel sheet 2 and the second steel sheet 4, the transformer is also promoted gradually, and until first bolt 41 can not be screwed, contained angle is zero between first steel sheet 2 and the second steel sheet 4, and the transformer is lifted to maximum height. The first bolts 41 on the 2 universal wheels are screwed by the same method, after the operation is finished, the transformer is completely separated from the ground, the lifting height is the difference value between the heights of the first steel plate 2 and the second steel plate 4, and the whole transformer is supported by the connecting structure of the transverse plate 21 and the connecting plate 22. The staff can promote the transformer and remove, because the existence of universal wheel, can realize the direction regulation of transformer transport, and then finally realized lifting and transport of transformer.
