AI Technical Summary
Existing tunnel construction survey rock mass sidewall drilling and sampling devices have poor position adjustment flexibility, making it difficult to adapt to the complex and ever-changing rock mass sidewall sampling scenarios inside tunnels. Furthermore, they require repeated disassembly, assembly, and relocation of the entire machine, which is time-consuming and labor-intensive.
The sampling mechanism employs a rectangular support frame and a multi-level limiting mechanism. Through the cooperation of the sliding mechanism, rotating ring, lifting part and adjusting plate, it can achieve multi-dimensional adjustment, including horizontal sliding, circumferential rotation, vertical lifting and tilting fine adjustment. Combined with the auxiliary fixing mechanism and self-locking casters, it ensures that the device is stable in the working position.
It improves the efficiency of sampling point adaptation, ensures the accuracy of drilling angle and sampling integrity, enhances the operational stability and survey efficiency of the device, and adapts to the diverse sampling needs of irregular rock mass sidewalls.
