AI Technical Summary
In the long-term use of existing road crack repair devices, the grouting gun needs to be supported to maintain a certain angle of movement, which leads to fatigue of construction workers and instability in the grouting process.
A road crack repair grouting device was designed, which uses inclined support columns and pulley assemblies to support the grouting gun. The pulley assembly moves with the nozzle to reduce movement resistance, the inclined support columns provide stable support, replace manual support to maintain the grouting angle, and the spring support adapts to road surface undulations.
This achieves stability and labor-saving in the grouting process, reduces the fatigue of construction workers, ensures accurate injection of repair fluid, and improves repair quality.
