Overturn frame of bridge inspection vehicle and bridge inspection vehicle

Abstract

The invention relates to a roll-over stand of a bridge detection vehicle and the bridge detection vehicle. The roll-over stand of the bridge detection vehicle comprises longitudinal beams, an upper transverse beam and a lower transverse beam, the upper transverse beam and the lower transverse beam are connected to the positions, between the two longitudinal beams, of the upper ends and the lower ends of the two longitudinal beams, and the two longitudinal beams, the upper transverse beam and the lower transverse beam are all box beams formed by splicing plates. The roll-over stand structure of the bridge detection vehicle is not only low in weight but also has quite high anti-bending rigidity and torsional rigidity, thus, the problem of design contradiction between the structure weight and the structure rigidity can be effectively solved, and the operation safety and stability of the whole bridge detection vehicle are ensured.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to an overturn frame of a bridge detection vehicle and a bridge detection vehicle. Background technique [0002] The bridge inspection vehicle (referred to as the bridge inspection vehicle) is a special vehicle used for bridge inspection. During the operation, the upper vehicle mechanism is turned over to work below the bridge deck. The overturning frame is a key component connecting the alighting and loading mechanisms, and the overturning frame transmits the overturning load and moment to the undercarriage to ensure the safety and stability of the bridge inspection vehicle during operation. At the same time, since the operators have to work under the bridge, it is required that the turning frame should have the function of normal crossing of the personnel. [0003] The existing structure of the overturning frame of the bridge inspection vehicle adopts a plurality of stee...

AI Technical Summary

Problems solved by technology

[0004] Since the overturn frame of the bridge inspection vehicle is outside the overturning line of the vehicle, the increase in its own weight will not only make the vehicle overweight, but also affect the stability of the vehicle, so the design will limit the weight of the overturn frame

In the existing technical solution, the structural rigidity of the tilt frame designed due to the weight limit cannot meet the requirements, resulting in an increase in the deflection of the boarding mechanism, which affects the safety and stability of the vehicle operation
