Description

Technical Field

[0001] This utility model relates to the technical field of underground tunnel construction equipment, and in particular to a pipe bracket device for use on an anchor bolt trolley. Background Technology

[0002] As one of the main support methods in underground engineering (such as mine roadways, tunnels, and slope reinforcement), rock bolt support's core principle is to anchor unstable rock masses to stable rock masses through the interaction between the rock bolts and the soil, thereby forming an integral support structure. Rock bolt trolleys are core support equipment in modern underground engineering, significantly improving construction efficiency and safety through mechanized drilling, grouting, and rock bolt installation. The rock bolt machine head, as a key component in rock bolt construction, has its technological development closely related to engineering needs.

[0003] The hydraulic pipeline routing of existing mechanized drilling and anchoring trolleys is relatively complex, and the space at the anchoring head is usually limited, making pipeline routing difficult. If the hydraulic pipeline cannot be laid in the existing track, it will hinder the convenience and anti-interference of construction. Moreover, the existing pipe laying devices mostly use steel chain structures, which are far inferior to steel strands in terms of flexibility, strength utilization, fatigue resistance, and construction economy. They are only suitable for specific low-speed, short-distance, and low-precision stress scenarios. However, under the core requirements of modern engineering for materials that are "high-strength, highly adaptable, and low-maintenance," the limitations of steel chains are particularly obvious.

[0004] Therefore, it is necessary to propose a pipe support device for anchor bolt trolleys. The pipe support device can improve the anti-interference of the pipe by arranging the pipe in the pre-set track. The steel strand structure has the characteristics of high strength, high toughness, corrosion resistance and easy construction, which can improve the structural performance and reduce material costs.
