The output end of the electric push rod is connected to a sliding block, and a moving wheel is installed at the bottom of the sliding block. When the drilling rig needs to be moved, the electric push rod is activated, extending it and causing the moving wheel to descend and contact the ground, thus supporting the drilling rig. The rig can then be easily moved. The guide rod and limit plate ensure the stability and safety of the sliding block during movement, preventing excessive movement. This design allows the drilling rig to be moved quickly and easily to the designated location even in complex environments such as tunnels, greatly improving work efficiency.

[0018] Comprehensive Improvement in Practicality: This utility model comprehensively solves the problems of unstable support and inconvenient movement of existing pneumatic anchor drilling rigs in coal mines through a series of structural improvements. From ensuring stability during drilling operations to facilitating operation during movement, optimizations have been made, significantly enhancing the efficiency and effectiveness of the pneumatic anchor drilling rig and improving its practicality in actual working scenarios such as coal mining.
