Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision devices, in particular to an anti-collision device on the top of a rotary drilling rig mast. Background Art

[0002] Anti-collision devices on the top of rotary drilling rig masts are widely used in various pile foundation projects, especially in construction environments with limited space or numerous obstacles. These devices significantly improve the safety and efficiency of rotary drilling rigs, reducing the risk of equipment damage and casualties caused by collisions.

[0003] The existing rotary drilling rig mast still has the following aspects to be improved during use:

[0004] 1. The top of the rotary drilling rig mast is often damaged. If the top of the mast is damaged, it may cause the overall structural stability to decline, thus affecting the overall safety and stability of the drilling rig. This may lead to safety accidents during construction and pose a threat to operators and the surrounding environment.

This compromises the accuracy and stability of the drilling rig, making it difficult to achieve the desired depth and accuracy. This not only reduces work efficiency but also increases the number of repetitive operations, thereby increasing costs. Utility Model Content
