Anti-rollover mechanism and system for truss type bridge inspection vehicle

Abstract

The invention discloses an anti-rollover mechanism for a truss type bridge inspection vehicle. The mechanism comprises four self-propelled support wheels (10) mounted at the bottom end of an auxiliary frame, auxiliary support wheels (20) arranged on one side in the truss extension direction, horizontal telescopic oil cylinders (24), vertical support leg oil cylinders (25) and support traveling wheels (26) at lower ends of the vertical support legs, wherein each auxiliary support wheel comprises a horizontal support leg box (21) mounted on an upper vehicle auxiliary beam (30), an L-shaped telescopic support leg (22) and a vertical support leg (23), one end of each L-shaped telescopic support leg is sleeved with each horizontal support leg box, and each vertical support leg is sleeved with the other end of each L-shaped telescopic support leg. The bridge inspection vehicle has at least six support points, and support forces of the auxiliary support wheels can be adjusted dynamically, so that the whole vehicle is balanced bilaterally and is kept in the safety coefficient range.

Description

technical field [0001] The invention relates to an anti-tipping mechanism and system of a bridge maintenance vehicle, in particular to an anti-tipping mechanism and system of a truss-type bridge maintenance vehicle, belonging to the field of bridge maintenance and maintenance machinery. Background technique [0002] The bridge maintenance vehicle is a special equipment for bridge inspection. The truss-type bridge maintenance vehicle is a kind of bridge maintenance vehicle. It adopts a channel-type working platform, which has good stability and large bearing capacity. When in use, inspection personnel can easily enter the platform from the bridge deck or return to the bridge deck. [0003] The truss-type bridge maintenance vehicle is mainly composed of four parts: the chassis vehicle, the upper working device, the hydraulic system and the electric control system. In the working state, the maintenance vehicle needs to extend the upper working device out of the vehicle to reach...

AI Technical Summary

Problems solved by technology

However, since maintenance personnel need to walk on the truss to observe and maintain different parts of the bridge, the position of the center of gravity of the vehicle will change, which will cause the center of gravity of the vehicle to exceed the supporting surface. When the supporting ground is uneven, it will easily cause the center of gravity Exceeding the supporting surface, causing the whole vehicle to overturn, resulting in serious safety accidents
