[0042] The working principle of this utility model is as follows:

[0043] Under the action of the emulsion pump, the telescopic jack 4 is retracted, causing the support jack 6 to descend to its lowest position. Then, the upper clamp 9 and the lower clamp 10 are interlocked to clamp the base bridge 35, and the upper clamp 9 and the lower clamp 10 are fixedly connected by bolts and nuts. At this time, the lifting clamp 8 is located in the middle of the base bridge 35. Then, the telescopic jack 4 is extended, driving the support jack 6 to rise, so that the base bridge 35 leaves the ground and remains suspended. The transport trolley 1 is pulled, so that the transport trolley 1 moves on the ground rail 2 and gradually approaches the base assembly component 36. When the base bridge 35 reaches above the main rib U-shaped groove 37 of the base assembly component 36, the telescopic jack 4 is retracted, and the base bridge 35 is placed in the main rib U-shaped groove 37. The bolts and nuts between the upper clamp 9 and the lower clamp 10 are then removed. Then, control the telescopic jack 4 to extend, support jack 6 to rise again, and control the transport trolley 1 to gradually move away from the base assembly component 36 along the ground rail 2.
