Span-type steel structure platform for bridge overhaul system

Abstract

The invention discloses a span-type steel structure platform for a bridge overhaul system, comprising a supporting device and an operating platform, wherein a linear sliding device is arranged on the operating platform, the operating platform slides on the supporting device through the linear sliding device, an overhaul trolley is arranged on the operating platform, and the operating platform is connected with a sliding driving device. According to the invention, by arranging the operating platform on the supporting device, the operating platform can be driven by moving the supporting device so as to realize segmented overhaul of a bridge; when the operating platform encounters a bridge pier, the operating platform slides to one side of the supporting device through the linear sliding device so as to avoid the bridge pier; and after the operating platform crosses the bridge pier, the operating platform slides to the reverse direction to reset so as to overhaul the bridge continuously. The device avoids the trouble of dismounting the overhaul device in the overhaul process when encountering the bridge pier, so that the overhaul period is greatly saved.

Description

technical field [0001] The invention relates to bridge detection, maintenance and maintenance equipment, and specifically designs a spanning steel structure platform of a bridge maintenance system. Background technique [0002] 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. When overhauling a bridge, an overhaul workbench is generally set up under the bridge, and the bridge is driven section by section by the driving device to move the overhaul workbench. Some bridges have pier...

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

When overhauling a bridge, an overhaul workbench is generally set up under the bridge, and the bridge is driven section by section by the driving device to move the overhaul workbench. Some bridges have piers. When encountering bridge piers during the overhaul process, it is often necessary to remove part of the overhaul device and wrap the overhaul frame around After passing the bridge pier, rebuild the maintenance workbench, which will waste a lot of maintenance time, prolong the maintenance period, and greatly increase the maintenance cost
