Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine tunneling equipment, and in particular relates to an anchor bolting device for a tunneling and anchoring machine. Background Technology

[0002] A roadheader is a type of excavating machinery widely used in tunneling, underground development, mining, and other construction fields. As the name suggests, roadheaders are mainly used for rock drilling and anchoring. Their main functions include tunneling, underground engineering excavation, and reinforced concrete structure support. Anchor bolting machines, also known as soil nailing machines or pneumatic impact machines, are primarily used for rock and soil anchoring, roadbed and slope treatment, deep foundation pit support, tunnel surrounding rock stabilization, landslide prevention, underground engineering support, and high-rise building foundation treatment. They are also suitable for non-prestressed anchor support in deep foundation pit shotcreting and slope soil nailing projects.

[0003] Comparing with Chinese Patent No. CN211448727U, an anchor bolting machine device for an anchor bolting drilling rig is disclosed, including an anchor bolting machine, characterized in that: it further includes a lifting seat, the anchor bolting machine being movably mounted on the lifting seat; a drive cylinder is mounted on the lifting seat, the anchor bolting machine being mounted on the free end of the drive cylinder; a guide seat is mounted on the lifting seat, the guide seat being provided with a guide groove, and a guide rod sliding through the guide groove is mounted on the anchor bolting machine.

[0004] However, the aforementioned patented anchor bolting machine can only adjust the working range by sliding the anchor bolting machine through the lifting seat. In actual use, due to site limitations, the working angle cannot be flexibly adjusted, making it inconvenient to use. Moreover, the support is not stable enough, affecting the anchoring effect. Therefore, a new device needs to be designed. Utility Model Content
