Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel bridge maintenance equipment, and in particular to a multifunctional coating repair device for repainting steel bridges. Background Technology
[0002] A search of Chinese patents revealed CN219490633U, a bridge coating repair device, includes a movable base. The upper end of the movable base houses a liquid pump and a liquid storage tank. A connecting pipe is located inside the liquid storage tank, and a curved pipe is fixedly connected to the top of the connecting pipe. A conduit is provided at the outlet of the liquid pump. A rotating frame is rotatably connected to the right side of the movable base, and a bridge coating spreading roller is rotatably connected to the bottom of the rotating frame. A nozzle is fixedly connected to the upper right end of the rotating frame near the bridge coating spreading roller. This invention relates to the field of bridge coating repair technology. In this bridge coating repair device, an air compressor draws in and compresses external gas through an extraction pipe. The compressed gas is then introduced into a vortex tube through an injection pipe. The vortex tube draws in and compresses the external gas, and through vortex conversion, converts the compressed air into cold and hot air. The cold air is injected into a spray plate through a cold air pipe, and the spray plate sprays cold air to blow onto the ground in front of the device.
[0003] Existing coating repair devices cannot stir the coating. Generally, the coating in these devices is stored in a coating tank. During use, some components in the coating may precipitate, affecting the quality of the coating and thus the quality of the repair. This also makes repair inconvenient. Furthermore, the nozzles of these devices are usually fixed. When repairing large areas, the nozzles cannot complete the repair in one go. Because the nozzles are fixed to the device, the device needs to be constantly moved to adjust the nozzle position until the repair is completed, which is very cumbersome, increases workload, reduces repair efficiency, and is inconvenient to use. To solve these problems, we propose a multi-functional coating repair device for recoating steel bridges. Utility Model Content
