Leaping bridge maintenance system

technical field

The invention relates to bridge detection, maintenance and maintenance equipment, and specifically designs a spanning bridge maintenance system.

Background technique

Reinforced concrete bridges have the advantages of simple structure, low cost, long service life, easy installation, and small maintenance and maintenance workload, and are widely used in railway trunk lines and highways. 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, fractured diaphragms, corrosion of pedestrian brackets and bolts directly endanger the safety of the bridge, so the bridge needs to be inspected and repaired regularly. Inspection and maintenance equipment must be built before bridge inspection and maintenance. The commonly used inspection and maintenance equipment is mainly maintenance vehicles. The construction method is to first build an inspection frame on the bridge and then install the maintenance vehicle on the inspection frame. The built maintenance frame can be dismantled, but the process of building the maintenance frame to ensure that it is firmly attached to the bridge is relatively cumbersome, and it will take a lot of time to disassemble it.

Contents of the invention

In order to solve the above technical problems, the present invention provides a spanning bridge maintenance system.
