detailed description

Below in conjunction with Fig. 1-Fig. 11 specific embodiment of the present invention is described in further detail: a kind of electric power construction site construction multifunctional trolley, this trolley comprises wheel 4, trolley floor 1 and trolley push rod 3, hoisting device 5, tool box 6 , pallet 7 and lighting device 8 (as shown in Figure 1), dolly push rod 3, hoisting device 5, tool box 6, pallet 7 and lighting device 8 are all arranged on the dolly floor 1.

Four groups of stable support mechanisms 2 are symmetrically arranged on the left and right sides of the trolley bottom plate 1 respectively. The stable support mechanisms 2 include a support screw 21 and a support plate 22. The support screw 21 is located in the threaded through hole provided on the support plate 22. Here, we can The four sets of stable support mechanisms 2 are directly welded on the bottom plate 1 of the trolley, and at the same time, we can also connect the stable support mechanisms 2 and the bottom plate 1 of the trolley in a hinged manner. When connecting the stable support mechanism 2 and the bottom plate 1 of the trolley in a hinged manner, a U-shaped groove needs to be provided at the front end of the support plate 22, and the two opposite vertical plates of the U-shaped groove are provided with through holes of the same diameter. The trolley bottom lugs 11 with the same through holes are arranged symmetrically, and the pin shaft passes through the through holes on the trolley bottom lugs 11 and the support plate 21 to hinge the stable support mechanism 2 on the trolley bottom 1. When the stable support mechanism 2 is retracted, , in order to facilitate the fixing of the stable support mechanism 2, we fixedly set an L-shaped elastic slot 14 for fixing the stable support mechanism 2 on the bottom plate 1 of the trolley. During construction work, adjust the four support screws 21 to make the trolley wheels 4 off the ground, and use the support screws 21 to support the trolley, which improves the safety and stability of the trolley during climbing operations.
