Bridge detection vehicle

Abstract

The invention relates to a bridge detection vehicle which comprises a supporting leg mechanism, the supporting leg mechanism comprises a vehicle frame, an oil cylinder, a wheel carrier and a supporting leg component, the supporting leg component is provided with a first hinge position, a second hinge position and a third hinge position, the first hinge position is hinged to the vehicle frame, the second hinge position is hinged to the wheel carrier, the third hinge position is hinged to one end of the oil cylinder, the other end of the oil cylinder is hinged to the vehicle frame, the third hinge position is located between the first hinge position and the second hinge position, and the first hinge position, the second hinge position and the third hinge position are located on the same plane. The bridge detection vehicle is reasonable in hinge position arrangement, light in structure and simple in process, and can solve the problem that due to unreasonable hinge point design of the existing supporting leg mechanism of the bridge detection vehicle, part of hinge point loads are too large, and local structure damage is caused when the loads are transmitted to a vehicle frame platform; and the problem that at present, the machining technology of supporting leg component hinge holes of the supporting leg mechanism of the bridge detection vehicle is complex is solved.

Description

[0001] This application is a divisional application with an application date of September 7, 2015, an application number of 201510563033.1, and an invention title of "A Outrigger Mechanism and Bridge Inspection Vehicle". technical field [0002] The invention relates to the field of engineering machinery, in particular to a bridge inspection vehicle. Background technique [0003] At present, the outrigger mechanism used on the bridge inspection vehicle includes an oil cylinder, a vehicle frame and outrigger components. The oil cylinder, vehicle frame and outrigger components form a stable triangular structure. By adjusting the expansion and contraction of the oil cylinder, the outrigger components can be adjusted Support and recovery, change the vertical distance between the roller and the ground to realize the bearing function; in addition, the outrigger mechanism also includes rollers, which are driven by a reducer to realize the forward and backward movement of the bridge ...

AI Technical Summary

Problems solved by technology

The above-mentioned outriggers are provided with hinged holes at the three corners of the obtuse triangle structure. Not only is the process complicated during processing, but it is difficult to ensure the relative dimensional accuracy of the three hinged holes. , the hinge points of the frame and outrigger components, and the hinge points of the oil cylinder and outrigger components are overloaded, and the vertical load cannot be decomposed and transferred to the frame platform, resulting in some structural parts of the frame platform due to excessive load.
