Supporting leg mechanism and bridge detection vehicle

Abstract

The invention discloses a supporting leg mechanism and a bridge detection vehicle. The supporting leg mechanism comprises a vehicle frame, an oil cylinder, a wheel frame and a supporting leg component. The supporting leg component is provided with a first hinged position, a second hinged position and a third hinged position. The first hinged position is hinged to the vehicle frame, the second hinged position is hinged to the wheel frame, the third hinged position is hinged to one end of the oil cylinder, the other end of the oil cylinder is hinged to the vehicle frame, and the third hinged position is located between the first hinged position and the second hinged position. The first hinged position, the second hinged position and the third hinged position are located on the same plane. The supporting leg mechanism is reasonable in hinged position layout, light in structure and simple in process, the problem of local structure damage caused by the facts that loads on part of hinged points are too high due to unreasonable hinged point design of a supporting leg mechanism of a bridge detection vehicle at present and are transmitted to the position of a vehicle frame platform can be solved, and the problem of complexity in a process for machining hinged holes of the supporting leg component of the supporting leg mechanism of the bridge detection vehicle at present is solved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an outrigger mechanism and a bridge inspection vehicle. Background technique [0002] 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 inspection vehicle. [0003] In the prior art solutions, the outrigger components used in the outrigger mechanism are generally designed as an obtuse triangle structure, and the three hinge point...

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.
