[0002] In a certain project, the roof adopts a shaped inclined roof, and the inclined roof is curved from the west side to the east side. The mechanical and electrical pipelines such as air ducts under the inclined roof are located between the roof and the roof support steel structure. Since the height of the mechanical and electrical pipelines from the ground is about 9m, when using an 8m lifting vehicle for mechanical and electrical pipeline construction, the lifting vehicle needs to be raised to a height of 7.5m. Although this height does not exceed the applicable range of the lifting vehicle, since the raised height is already close to the limit of the lifting vehicle, the top of the lifting vehicle shakes significantly during construction, and the possibility of the lifting vehicle overturning during the construction of mechanical and electrical pipelines is very high.

[0003] The purpose of the utility model is to overcome the defects of the prior art, and provide an anti-overturning device for a lifting vehicle used for hoisting mechanical and electrical pipelines in a steel structure, which can ensure the stability of the lifting vehicle body even when the lifting vehicle body is raised to the limit height, and prevent the lifting vehicle body from overturning.

[0004] To achieve the above technical effects, the utility model provides an anti-overturning device for a lifting vehicle used for hoisting mechanical and electrical pipelines in a steel structure, which includes:

[0005] A lifting vehicle body, on the top of which along the lifting direction is provided an operation platform;

[0006] An anti-overturning mechanism for connecting the operation platform with the steel structure, the anti-overturning mechanism includes a plurality of towing ropes, the first ends of the plurality of towing ropes are fixedly connected to the operation platform, and the second ends are all hung and connected to the upper chord of the steel structure.

[0007] Preferably, a plurality of fixed snap rings for fixedly connecting the first ends of the plurality of towing ropes are respectively arranged on the outer peripheral side of the operation platform.

[0008] Preferably, a hook is fixedly connected to the second end of each towing rope, and a plurality of lower hanging structural members for respectively hanging and connecting the plurality of hooks are arranged at the bottom of the upper chord of the steel structure.

[0009] Due to the adoption of the above technical solution, the technical effects obtained by the utility model are:

[0010] Effectively solve the problem that the stability of the lifting vehicle is poor and it is easy to overturn when the lifting vehicle is raised to the limit height during the construction of mechanical and electrical pipelines in the steel structure, and ensure the safety of steel structure construction.
