Description

Bridge maintenance system steel structure maintenance platform

technical field

The utility model relates to bridge detection, maintenance and maintenance equipment, and specifically designs a steel structure maintenance platform for a 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. 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 crossing the bridge pier, the maintenance workbench will be rebuilt, which will waste a lot of maintenance time, prolong the maintenance period, and greatly increase the maintenance cost.

Utility model content

In order to solve the above technical problems, the utility model provides a bridge maintenance system steel structure maintenance platform.

The technical solution is as follows: a steel structure maintenance platform for a bridge maintenance system, the key of which is that it includes a support device and an operation platform, the operation platform is provided with a linear sliding device, and the operation platform is placed on the support through the linear sliding device. Sliding on the device, the operating platform is provided with a maintenance trolley, and the operating platform is connected with a sliding drive device. With this technical solution, the operating platform is set on the supporting device, and the operating platform can be driven by moving the supporting device to realize the section-by-section maintenance of the bridge. When encountering a bridge pier, the operating platform is slid to one side of the supporting device through a linear sliding device. , so as to give way to the bridge pier.

With this design, when the height of the bridge ground is uneven and the height of the operation platform needs to be adjusted, the cooperation of the guide rod installed on the hanging basket and the guide through hole can guide the operation platform to prevent the operation platform from shaking violently during the adjustment process. affect the security of the operation.

The inner edges of the two supporting platforms are respectively provided with pier rollers, and the axis lines of the pier rollers are perpendicular to the horizontal plane. With this design, when crossing the bridge pier, the two support platforms are driven forward by the hanging basket, and the pier-crossing rollers on the inside of the support platform roll over the side of the bridge pier, which reduces the friction coefficient between the inner edge of the support platform and the side of the bridge pier, and saves effort when crossing , At the same time, it can also prevent the support platform from scratching the pier.

The above-mentioned operating platform is provided with a maintenance guide slideway, and the maintenance trolley moves linearly through the maintenance guide slideway, and protective fences are provided around the operation platform. With this design, the maintenance trolley slides inside the maintenance guide, and the maintenance trolley is more stable. Especially when the operation platform is slightly tilted due to inconsistent adjustment of the suspension ropes at both ends, the maintenance trolley is always bound in the maintenance guide slideway and will not swim around. , and will not rush out of the operating platform.

Beneficial effect: the beneficial effect of adopting the utility model is that the operating platform is set on the supporting device, and the operating platform can be driven by moving the supporting device so as to realize the section-by-section maintenance of the bridge. Slide to one side of the supporting device to give way to the bridge pier. When the operating platform crosses the bridge pier, slide the operating platform in the opposite direction to reset it and continue to repair the bridge. This device avoids the need to remove the repairing device when encountering the bridge pier during the repair process The trouble, greatly saving the maintenance period.
