An inspection car that can be turned over automatically

Abstract

The invention provides an inspection vehicle capable of automatically overturning, comprising a moving system and a main truss, wherein the moving system is fixed on the main truss; the main truss is suspended on a walking rail through the moving system; the moving system comprises a control subsystem which is used for controlling the motion of the main truss; the main truss comprises a fixed walkway, a movable walkway and a four-bar linkage mechanism; the fixed walkway is fixed with the moving system; the movable walkway is hinged to the fixed walkway through the four-bar linkage mechanism; the movable walkway can downwards overturn in 180 degrees along a connection position, and is folded below the fixed walkway under the action of the four-bar linkage mechanism. According to the inspection vehicle capable of automatically overturning, the movable walkway can automatically overturn in 180 degrees and is folded below the fixed walkway in the process of passing through barriers, so that the inspection vehicle walks electrically in a closed triangular space range, the hindering from a diagonal draw bar is prevented, the inspection range is expanded, and the steel beam overhauling in full-bridge range at the outer side of the main truss of an inverted trapezoidal section bridge can be realized.

Description

technical field [0001] The invention relates to an inspection vehicle, in particular to an inspection vehicle that can be turned over automatically. Background technique [0002] With the rapid development of China's bridge industry, the market for bridge inspection vehicles is expanding. Bridge inspection vehicles can be divided into bridge deck inspection vehicles and fixed track inspection vehicles. The structure of the bridge-deck type inspection vehicle is complicated, the cost is high, and the inspection efficiency is relatively low. At present, most of the fixed track type inspection vehicles are used at home and abroad. The structure of the fixed track type inspection vehicle is relatively simple, but it is difficult for the inspection vehicle to pass through obstacles such as bridge portal frames and diagonal stays during the running process, and a special structure must be designed. At present, most of them use additional rails to increase the inspection vehicle o...

Problems solved by technology

The structure of the bridge-deck type inspection vehicle is complicated, the cost is expensive, and the inspection efficiency is relatively low. At present, most of the fixed track type inspection vehicles are used at home and abroad.

The structure of the fixed track type inspection vehicle is relatively simple, but it is difficult for the inspection vehicle to pass through obstacles such as bridge gantry and diagonal stays during the running process, and a special structure must be designed. At present, most of them use additional tracks to increase the inspection vehicle or use telescopic type or use rotation in the horizontal plane To avoid obstacles, one inspection vehicle needs to be installed in the space separated by the diagonal stay rods, and the cost of the track and the inspection vehicle will increase greatly.
