Wheeled robot used for eliminating and spraying fireproof anticorrosive coating on steel frame structure

Abstract

The invention provides a wheeled robot used for eliminating and spraying fireproof anticorrosive coating on a steel frame structure. The wheeled robot is characterized by comprising a frame, a permanent magnetic adsorption device, four symmetrically arranged travelling system, a repairing assembly, a high-definition camera, an infrared distance meter, a battery and a control system. The wheeled robot can be used alone or multiple wheeled robots are connected in series or in parallel, the automatic spraying area is larger, the working time is longer, and garbage collection is more thorough; andthe wheeled robot provided by the invention can continuously walk on complex steel environment work interfaces such as a ladder, a crossed wall surface, a curved surface and a circular arc and carryout polishing, spraying and detection operations. The wheeled robot provided by the invention can automatically eliminate and polish a fireproof coating and an anticorrosive coating of a shed-free steel frame supporting column of a railroad platform, sprays fireproof anticorrosive coating and can carry out all weather operations without influencing pass of G-series high-speed trains.

Description

technical field [0001] The invention belongs to the field of repair equipment, and relates to steel frame structure repair equipment, in particular to a wheeled robot used for clearing and spraying fireproof and anticorrosion coatings of steel frame structures. Background technique [0002] In recent years, with the rapid development of my country's high-speed railway, the new type of station platform column-free canopy and passenger station building with large-span and large-scale steel structures as load-bearing components have been widely used as the main structure. The structure has simple form, large span, and novelty. Beautiful and other features, as of October 2017, there are 514 high-speed rail passenger stations in operation, and the area of ​​high-speed rail steel structure canopies reaches 8,892,200m 2 . At present, steel structures such as column-free canopies in high-speed railway stations have been affected by the environment, and corrosion has occurred to vary...

AI Technical Summary

Problems solved by technology

2. Under the high-speed rail electrification line, the anti-corrosion coating is easily aged due to the catalysis of the catenary high-voltage current (about 30000v)

3. Due to the frequent passage of high-speed rail EMUs, its vibration will have a greater impact on the coating of the steel frame structure, and the coating is relatively easy to fatigue and crack or fall off

[0004] Difficulties in canopy coating repair and painting: 1. Since the high-speed railway operation time is during the day, the construction and maintenance time of the high-speed rail steel structure canopy can only be carried out during the night skylight time (0:00---4:00)

2. Due to the large span and high headroom of the high-speed rail passenger station, the operation is carried out at high altitude most of the time, and there are many driving equipment such as catenary, steel rails and ballast beds under the canopy above the operating high-speed rail line, making the operation difficult
