Bridge inspection vehicle traveling mechanism and bridge inspection vehicle

Abstract

The disclosure relates to a bridge inspection vehicle traveling mechanism and a bridge inspection vehicle. The traveling mechanism includes: a frame; a traveling member;a linear telescopic mechanism, one end thereof being hinged to the frame and the other end thereof being hinged to the traveling member, and the linear telescopic mechanism for driving the traveling member to be retracted upwardly or to be grounded downwardly;a second cylinder, one end thereof being hinged to the frame and the other end thereof being rotatable connected to an exterior of the linear telescopic mechanism, the second cylinder for driving the linear telescopic mechanism to be lifted upwards obliquely or to be perpendicular to the ground downwardly. By using the second cylinder to drive the linear telescopic mechanism to be lifted upwards obliquely or to be perpendicular to the ground downwardly, the disclosure can reduce the stroke of the linear telescopic mechanism compared with the prior art. Further, the small stroke of the linear telescopic mechanism and its installation below the frame can further avoid the problem of excessively large stroke of the single cylinder required by lifting height to affect the upper slewing space of the carriage.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a traveling mechanism of a bridge inspection vehicle and a bridge inspection vehicle. Background technique [0002] At present, the walking mechanism used on the bridge inspection vehicle is mainly composed of a vehicle frame, outriggers, oil cylinders and rollers. The traveling mechanism changes the vertical distance between the roller and the ground by adjusting the expansion and contraction of the oil cylinder. The outriggers are retracted in the non-working state, and the outriggers are extended in the working state. The rollers are supported on the ground to realize the load-carrying function. By driving the rollers, the bridge inspection vehicle can be driven. Operation. [0003] At present, the walking mechanism used by the bridge inspection vehicle mainly has the following two types: [0004] One is that the oil cylinder and the outriggers are respectively hinged on...

AI Technical Summary

Problems solved by technology

In this type of running mechanism, the vertical load transmitted by the rollers is directly transmitted to the frame. This force-bearing mode is better than that of the first type of running mechanism. For a large stroke, a certain space for the installation of the oil cylinder should be arranged on the upper part of the frame, thereby reducing the turning space of the boarding car and affecting the performance of the boarding function
