AI Technical Summary
Existing drill pipe straightening equipment relies on manual loading and unloading, resulting in low automation and impacting work efficiency and safety.
A hydraulic drill rod straightening machine was designed, which uses a feeding assembly consisting of a gantry frame, hydraulic head, drive motor, rocker arm and crossbar to realize automatic feeding and unloading of drill rods. It achieves precise straightening through the cooperation of cylinder and pressure block. The arc-shaped concave pressure block and base design enhance the contact area and stability.
It achieves fully automatic feeding and unloading of drill rods, improves the automation level and working efficiency of the straightening machine, ensures straightening accuracy, protects the surface quality of drill rods, and improves the safety and stability of equipment operation.
