Bridge inspection vehicle capable of adjusting track pitches

Abstract

The invention relates to a bridge inspection vehicle capable of adjusting track pitches, which comprises a truss, two portals, driving wheels, a driving device and a track pitch adjusting device. The two portals are respectively disposed at the left end and the right end of the truss, the driving wheels are arranged above the portals and match with an H-shaped track of a bridge, the driving device is connected with the driving wheels and used for driving the driving wheels to move along the H-shaped track of the bridge, the track pitch adjusting device comprises a roller structure and a slide plate structure, both the roller structure and the slide plate structure are disposed among the portals and the truss, the roller structure is fixed on the portals, the slide plate structure is fixed on the truss, the location of the slide plate structure corresponds to that of the roller structure, and the roller structure can move left and right on the slide plate structure along a truss extension direction so as to drive the portals to move left and right along the truss extension direction. The bridge inspection vehicle resolves the difficult problem that an existing bridge inspection vehicle runs unstably due to large track pitches and parallelism errors, and further runs stably.

Description

technical field [0001] The invention relates to bridge maintenance and overhaul equipment, in particular to a bridge overhaul vehicle with adjustable gauge, belonging to the technical field of bridge overhaul vehicle design and manufacture. Background technique [0002] After the completion of large and medium-sized steel bridges, frequent maintenance and repairs are required. Because the distance between the bottom of the bridge and the water surface or the road is too large, and the span between two piers is hundreds of meters or even thousands of meters, therefore, Generally, special maintenance equipment, that is, bridge maintenance vehicles, will be equipped under the bridge to complete the maintenance and maintenance work on the bottom surface of the bridge. [0003] The main structure of the existing bridge maintenance vehicle structure includes trusses, portal frames, driving wheels and driving devices. , The two ends of the right are respectively equipped with port...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of unequal track spacing, unguaranteed parallelism, and existence of included angles in the bridge maintenance vehicle in the prior art, and prevent the trolley from being locked due to the problem of track parallelism or the asynchrony of the drive mechanisms on both sides during the operation of the trolley, The invention provides a bridge maintenance vehicle with adjustable gauge
