Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically to a multi-station detection device for an anchor drilling rig. Background Technology

[0002] Currently, rock bolt support is a widely used reinforcement method in mine and tunnel drilling and blasting construction. During anchoring operations, pneumatic rock drills or rock drilling rigs are typically used for drilling, followed by manual grouting and installation of anchor bolts using a gantry or suspended platform. This method suffers from high labor intensity, low efficiency, and compromised worker safety. Therefore, equipment that automatically switches between drilling, resin application, and anchor bolt pushing positions is gradually being developed and used to address these issues. During construction, the switching between multiple work positions must be precise to prevent errors or deviations in each operation. However, current technology lacks a device to detect the multi-position switching of rock drilling rigs. This results in significant time consumption in switching the appropriate devices to the correct positions. If construction operations are performed before the correct positions are properly switched, inaccurate positioning will lead to subsequent repairs and rework, significantly wasting costs and reducing construction efficiency.
