An automatic leveling mechanism of an arch bridge inspection vehicle

Abstract

The invention relates to an automatic leveling mechanism for arch bridge inspection cars and belongs to the field of bridge inspection cars. The automatic leveling mechanism comprises an inspection frame, a work-gear lifting mechanism, a leveling connecting rack and a control system. The leveling connecting rack comprises a circular main rack, a lower connecting rack, two upper connecting racks, and a guide wheel assembly. The guide wheel assembly comprises a ring guide wheel assembly and a side guide wheel assembly. The lower connecting rack is fitly connected with the lower portion of the circular main rack through the guide wheel assembly. The upper connecting racks are respectively fitly connected with the upper portion of the circular main rack through the guide wheel assembly and driven by the worm-gear lifting mechanism. The circular main rack and the lower and upper connecting racks can slide relatively. The inspection frame is connectedly limited inside the circular main rack. When an inspection car moves uphill and downhill along an arch bridge, the circular main rack rotates at the set limit slope angle alpha; the leveling connecting rack and the control system coordinate to control adjustment, so that the inspection car is kept running horizontally stably. The automatic leveling mechanism is simple to design, and allows the inspection cars to stably and safely move uphill and downhill.

Description

technical field [0001] The invention relates to an automatic leveling mechanism of an arch bridge inspection vehicle, which belongs to the field of bridge inspection vehicles, and in particular relates to an arch bridge inspection vehicle. Background technique [0002] At present, the generally used bridge inspection vehicle in China is integrated with the running device. When it is necessary to stop and overhaul on a large-slope track, the frame and hoisting mechanism will be too steep, so that the inspector cannot be in a horizontal state on the frame or in the hanging basket to maintain balance, which is not conducive to detection and will affect the detection. Threat to the safety of personnel. Faced with the wide application of arch bridges and the increasing demand for inspection of arch bridges, the original leveling device can no longer meet the requirements of high efficiency, easy maintenance, safety and stability required by existing arch bridges. Therefore, it ...
