AI Technical Summary
Existing bridge concrete repair equipment does not thoroughly remove large particles of sand and soil, resulting in residual impurities that affect the quality of repair. Furthermore, the discharge pipe is prone to misalignment, causing the repair material to be inaccurately injected into the gaps, resulting in waste.
The design employs a combination of a splined shaft and a splined sleeve, which allows the rotating disc to drive the brush to rotate and clean the sand and soil in the cracks. A compression spring ensures that the brush makes full contact with the concrete surface. A cylinder drives the moving frame to adjust the height of the discharge pipe, and a buffer spring stabilizes the nozzle to spray out the repair material.
It effectively removes large particles of sand and soil, ensuring the bonding quality of repair materials, and the nozzle can smoothly inject into the gaps, avoiding resource waste and improving the stability and efficiency of the repair equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bridge maintenance equipment, and in particular to a rapid repair device for concrete damage. Background Technology
[0002] During bridge construction, inadequate curing of the concrete surface can lead to micro-cracks, affecting the aesthetics of the structure. Construction workers typically use repair agents to fill and repair these cracks.
