The connecting truss 3 is hoisted by two hoisting bodies 21 located at the two supporting trusses 1, and the two hoisting steel wires play a role in balancing the hoisting of the connecting truss 3.

[0030] In order to ensure the stability of the lifting movement of the connecting truss 3, the second embodiment of the utility model is a reference Figure 2 As shown. The number of supporting trusses 1 is one, and the hoisting body 21 is connected to the connecting truss 3 through the transition frame 4.

The transition frame 4 is a triangular structure, and the hoisting steel rope 211 of the hoisting body 21 is fixed to the upper end of the transition frame 4. The transition frame 4 is connected to the connecting truss 3 through two transition ropes 41 arranged at intervals, thereby playing the role of balancing the hoisting connecting truss 3.

[0031] Reference Figure 3 As shown, the support frame 22 includes a first vertical plate 221, a second vertical plate 222, a bottom plate 223 and a reinforcing plate 224. The two first vertical plates 221 are arranged at intervals, the two second vertical plates 222 are arranged at intervals and fixedly connected to the first vertical plates 221, the bottom plate 223 is respectively fixedly connected to the first vertical plate 221 and the second vertical plate 222 and is arranged below the second vertical plate 222, and the two reinforcing plates 224 are respectively fixedly arranged on the outer sides of the two first vertical plates 221 and abut against the support truss 1.
