AI Technical Summary

Technical Problem

The cast-injected pile drill rod is prone to inclination due to encountering hard objects during the drilling process, resulting in a decrease in construction efficiency.

Method used

An anti-tilt device including a drill rod, a drill bit, a slider, a guide rod, an elastic member, a clamp, a plug rod, a moving block and a screw rod are designed. Through the cooperation of the clamp and the moving block, the anti-bias block is fixed, and the position of the moving block is controlled by the cooperation of the driving gear and the transmission gear, the rapid installation and disassembly of the anti-bias block is achieved.

Benefits of technology

The installation and disassembly efficiency of anti-biased blocks is improved, and the time to replace anti-biased blocks is reduced, thereby improving the efficiency of drilling construction.
