Description

Technical Field

[0001] The invention belongs to the technical field of mining equipment and relates to a support and anchor drilling machine and a rock tunnel anchoring machine comprising the same. Background Art

[0002] During tunnel excavation operations, especially those involving geological conditions in rock tunnels, the cutting device of the anchor and excavator is only operated at a rate of about 35%, and most of the remaining time is used for anchor support. Low support efficiency is the main factor affecting the excavation progress of the entire machine.

[0003] At present, in order to adapt to large-section rock tunnels and improve operating efficiency, the existing integrated miner and anchor machine usually uses left and right drilling parts for support and anchor support. However, the setting of the left and right drilling parts makes the machine body wide, which leads to inflexible material transportation in the already narrow space. Moreover, the function of the anchor drilling rig is relatively simple and the operating position cannot be flexibly adjusted. The support efficiency is very low. Once the hole position is not aligned, the machine must be moved and adjusted, which seriously affects the excavation progress. When changing to other cross-section tunnels, a new anchor structure and supporting operating platform must be redesigned, which consumes more time, manpower and material resources, and the losses caused are immeasurable.

[0004] In view of this, it is particularly important to design an anchor drilling rig that is flexible in transportation, can adapt to different large-section tunnels, can quickly find holes and locate, and can efficiently perform anchor support operations. Summary of the Invention
