Bridge inspection vehicle device and method capable of self-adapting to track installation errors

Abstract

The invention provides a bridge inspection vehicle device and method capable of self-adapting to track installation errors. The device comprise walking tracks arranged on the left side and the right side of the bottom of a bridge, a driving trolley is hung on the walking tracks, a portal is fixedly connected with the lower end of the driving trolley, a vehicle frame is connected with the portal, and a track installation error adjusting mechanism is arranged between the driving trolley and the portal. The method for self-adapting to the track installation errors comprises the steps of releasing the corner of the inspection vehicle in the forward bridge direction, providing enough lateral rigidity for the two sides of walking wheels of the driving trolley, releasing the corner of the inspection vehicle in the transverse bridge direction, and enabling a vehicle frame to slide in a certain range in the transverse bridge direction. According to the invention, the forward bridge direction and the transverse bridge direction corners of the vehicle frame can be released to the maximum extent; the vehicle frame is prevented from generating additional bending moment, the structural safety of the vehicle frame is guaranteed, meanwhile, the walking wheels of the driving trolley can always act on driving tracks, the slipping phenomenon caused by disengagement or unbalanced stress of the walking wheels is avoided, and finally, the track clamping phenomenon caused by track gauge errors or desynchrony of the driving trolley can be prevented.

Description

technical field [0001] The invention relates to the field of bridge inspection and maintenance, in particular to a bridge inspection vehicle device and method for adaptive rail installation errors. Background technique [0002] Bridge inspection vehicles are mainly divided into two types: the first type is a mobile vehicle chassis type inspection vehicle that uses a car chassis to walk on the bridge deck and is equipped with electromechanical devices to transport personnel to the inspection position; the second type is specially designed according to the structural form of a specific bridge A special inspection vehicle installed on a fixed track. The bridge inspection vehicle described in this article is the second type [0003] The bridge inspection vehicle is a wheel-rail type mobile trolley that provides a special working platform for bridge inspection and maintenance personnel. On the walking track on the side, the frame is fixed under the driving trolley through the m...

AI Technical Summary

Problems solved by technology

[0003] The bridge inspection vehicle is a wheel-rail type mobile trolley that provides a special working platform for bridge inspection and maintenance personnel. On the walking track on the side, the frame is fixed under the driving trolley through the mast. The inspector controls the deceleration motor to drive the traveling wheel forward or backward along the track direction by operating the electronic control system to complete the bridge inspection work. After the inspection car is installed, the track If there is a slope or structural deformation, the tracks on both sides have height differences, gauge errors, and the asynchrony of the inspection vehicle during the traveling process, the following problems will occur: 1. On the slope track, the traveling wheels on the drive trolley along the bridge cannot Ensure that it always acts on the track, and there is a phenomenon of slippage; 2. The driving trolley is rigidly connected with the mast and the frame. When there is a height difference between the two sides of the track, it can only be adapted through the elastic deformation of the frame. Under the action of variable load, it will cause fatigue damage to the frame; 3. When there is a gauge error or the driving trolley on both sides of the track is out of sync, the driving trolley on the inspection car will get stuck on the track or cause serious wear to the track
