Telescopic boom structure and bridge inspection vehicle

Abstract

The invention discloses a telescopic arm structure of a bridge detecting vehicle and the bridge detecting vehicle. The telescopic arm structure comprises a basic arm and an extension arm, wherein the extension arm is arranged relative to the basic arm in a stretchable manner; the basic arm comprises four main chord members which are arranged in parallel and a plurality of connecting rods; the four main chord members comprises two upper chord members and two lower chord members; the four main chord members are connected to form a truss-type square beam structure, the upper part of which is opened; the lower main chord members are integrally moulded and are of a first trough type structure; and the extension arm is slidably matched with the first trough type structure. According to the technical scheme disclosed by the invention, the potential safety risk of operators and instruments and equipment can be reduced.

Description

technical field [0001] The invention relates to bridge inspection equipment, in particular to a telescopic arm structure of a bridge inspection vehicle and the bridge inspection vehicle. Background technique [0002] As an important bridge inspection equipment, bridge inspection vehicle mainly includes car body, on-board parts and jib. Among them, the telescopic arm structure of the boom is used as the working platform of the bridge inspection vehicle. The expansion and rotation of the telescopic arm structure realizes the free working range of the operators and ensures the safe and effective detection work of the operators and instruments and equipment. Therefore, the telescopic arm structure Rigidity and strength put forward high requirements. At the same time, the telescopic arm structure of the bridge inspection vehicle is in a cantilever state when it is working, and its own weight and rated load also have a great influence on the stability of the vehicle.

Problems solved by technology

[0005] As a working platform for operators, the telescopic boom structure has high requirements for its rigidity, strength and stability. The cost increases, and it will also affect the stability of the vehicle

In addition, in some key parts, such as the slideway, it is realized by welding the plate and the pipe, which requires high technology, and the stress concentration of the weld is easy to cause the structure to open and weld, which poses a potential safety hazard to operators and equipment. risk
