The mounting plate assembly is inserted into the upper part of the I-shaped steel 2 and connected through a first connecting piece 9. Corresponding first threaded holes 12 are arranged in the vertical direction of the two connecting plates 5 and the upper flange 201, and the first connecting piece 9 is screwed through the first threaded holes 12.

[0032] In order to improve the contact area and connection strength between the mounting plate assembly and the I-shaped steel 2, the length of the mounting plate assembly is greater than the width of the I-shaped steel 2.

[0033] Referring to Figure 6 and Figure 7 As shown, a through long hole 401 adapted to the lifting belt 7 is arranged in the middle of the base 4 along the length direction of the base 4, and the lifting belt 7 is arranged in the through long hole 401. The lifting belt 7 of the present embodiment is of a flat structure, so the through long hole 401 is a long hole, and the base 4 can slide along the lifting belt 7 to a suitable position, so that the two ends of the lifting belt 7 can be hung on the hooks 101, and the mounting plate assembly can be inserted into the upper part of the I-shaped steel 2, and the mounting plate assembly is inserted into the upper flange 201 and the web 203, and can be adaptively connected with the I-shaped steel 2. The first connecting piece 9 passes through the first threaded holes 12 of the upper flange 201 and the two connecting plates 5 to fix and connect the upper flange 201 and the two connecting plates 5, and then fix and connect the mounting plate assembly to one end of the I-shaped steel 2. The mounting mode of the mounting plate assembly on the other side of the I-shaped steel 2 is the same, so that the mounting plate assemblies of the two lifting units are respectively fixed and mounted at the two ends of the I-shaped steel 2, and the I-shaped steel 2 is lifted from the two sides in the length direction, which can reduce the phenomenon that the I-shaped steel 2 and the vacuum circuit breaker are high and low at the two sides in the length direction during lifting, and the stability of the I-shaped steel 2 and the vacuum circuit breaker during lifting can be improved.

[0034] When the mounting plate assembly is inserted into the end of the I-shaped steel 2, and the two ends of the lifting belt 7 are hung on the hooks 101, the mounting plate assembly will not deviate in the length direction of the lifting belt 7, so the lifting belt 7 and the base 4 are connected by a second connecting piece 10. Specifically, the base 4 is provided with a limiting threaded hole 402 penetrating the through long hole 401, the limiting threaded hole 402 is located in the middle of the base 4, the second connecting piece 10 is screwed with the limiting threaded hole 402, and the end of the second connecting piece 10 can press the lifting belt 7 in the base 4 by tightening the second connecting piece 10.

By connecting the L-shaped plates 8 with the lower flange 202 of the I-shaped steel 2, the mounting plate can be installed in cooperation, the contact area of the mounting plate with the I-shaped steel 2 is further improved, the stability of the mounting plate when connected with the I-shaped steel 2 is improved, and the phenomenon of large amplitude shaking of the I-shaped steel 2 and the vacuum circuit breaker thereon is reduced.

[0036] The first connecting piece 9, the second connecting piece 10 and the third connecting piece 11 of the embodiment are all fastening bolts with different lengths.

[0037] The two end portions of the I-shaped steel 2 of the prior art both have a plurality of prefabricated connecting holes 204 for fixed connection with the mounting seat on the power pole. In order to make the L-shaped plate 8 not affect the direct installation of the I-shaped steel 2 after being lifted to the preset position, the width of the L-shaped plate 8 along the length direction of the I-shaped steel 2 is less than the vertical spacing between the prefabricated connecting hole 204 and the end portion of the I-shaped steel 2, so that after the I-shaped steel 2 is lifted to the mounting seat of the power pole, the third connecting piece 11 and the first connecting piece 9 can be disassembled after the I-shaped steel 2 is fixedly connected with the mounting seat.
