Description

Technical Field

[0001] The utility model relates to water conservancy water delivery tunnel excavation anchor rod construction equipment, in particular to a single-arm anchor rod drilling and anchoring machine for water delivery tunnel excavation. Background Art

[0002] Currently, water tunnel excavation anchor bolting construction primarily utilizes pneumatic anchor bolting rigs for manual drilling and anchoring agent installation. Because pneumatic anchor bolting rigs are powered by high-pressure gas, they are not only noisy and dusty during operation, but also have low drilling efficiency and high labor intensity for workers. Some water tunnel excavations also utilize single-arm hydraulic anchor bolters for internal anchoring. Currently deployed hydraulic anchor bolting rigs generally lack temporary support and work platforms, resulting in disconnected work processes and impacting work efficiency. Therefore, there is an urgent need for a device that can achieve mechanized anchoring, integrating mechanized drilling with temporary support, manual loading of anchoring agents on a work platform, and mechanized tightening.
