Spanning type bridge maintenance system

Abstract

The invention discloses a spanning type bridge maintenance system which comprises two travelling mechanisms, two maintenance trolley frames and a maintenance platform. The two travelling mechanisms as well as the two maintenance trolley frames are arranged on the two sides of a bridge oppositely. The maintenance trolley frames travel through the travelling mechanisms. The maintenance platform is arranged between the two maintenance trolley frames in a spanning mode. Since pre-buried barrels are arranged in the bridge in advance, support suspension arms can be directly inserted into the pre-buried barrels for paving travelling sleepers when the bridge needs to be maintained, the traveling sleeps are paved on the two sides of the bridge and do not influence passing of pedestrians and vehicles. If bridge piers exist in the maintenance process, an operating platform is made to slide towards one side of a supporting device through linear sliding devices so as to recede for the bridge piers; and after the operating platform spans the bridge piers, the bridge can be maintained as long as the operating platform is made to slide reversely and restored in position, and by adoption of the spanning type bridge maintenance system, the trouble that a maintenance device needs to be dismounted when the bridge piers exist in the maintenance process is avoided.

Description

Technical field [0001] The invention relates to bridge inspection, maintenance, and maintenance equipment, and specifically designs a spanning bridge inspection and repair system. Background technique [0002] Reinforced concrete bridges have the advantages of simple structure, low cost, long life, easy installation, small maintenance and maintenance workload, etc., and are widely used in railway trunk lines and highways. However, as time goes by and the external environment changes and other factors, serious diseases such as beam cracks, exposed steel bars, diaphragm breaks, pedestrian brackets and bolt corrosion, etc. directly endanger the safety of the bridge. Therefore, the bridge needs to be inspected and repaired regularly. The inspection and maintenance equipment must be built before the inspection and maintenance of the bridge. The commonly used inspection and maintenance equipment is mainly an inspection vehicle. The method of construction is to build an inspection frame...

AI Technical Summary

Problems solved by technology

However, with the passage of time and changes in the external environment and other factors, serious diseases such as cracks in the beam body, exposed steel bars, broken diaphragms, corrosion of pedestrian brackets and bolts directly endanger the safety of the bridge, so the bridge needs to be inspected and repaired regularly

Before inspecting and repairing the bridge, the inspection and maintenance equipment must be built first. The commonly used inspection and maintenance equipment is mainly the inspection vehicle. The built maintenance frame can be dismantled, but it is cumbersome to build the maintenance frame to ensure that it is firmly attached to the bridge, and it will take a lot of time to disassemble it
