Description

Technical Field

[0001] This utility model relates to the field of tunneling and anchoring machine technology, specifically to a tunneling and anchoring machine with a quick assembly and disassembly mechanism. Background Technology

[0002] Underground roadheader and anchor machine is a type of mechanical equipment that integrates roadheading and anchoring functions. It is widely used in roadway excavation and support operations in coal mines, metal mines, and non-metal mines. It can significantly improve excavation efficiency, reduce the labor intensity of workers, and improve operational safety.

[0003] The working principle of a roadheader / rock cutter mainly includes the following aspects: Roadheading: The roadheader cuts the tunnel using its front-end cutting section. The cutting section is typically equipped with high-strength cutting teeth, effectively breaking rocks or coal seams. Anchoring: Simultaneously with roadheading, the roadheader can perform anchoring operations using its built-in bolting machine. The bolting machine drills holes in the tunnel wall and installs bolts or cables to enhance the stability of the tunnel. Loading and Transportation: Roadheaders are typically equipped with loading mechanisms and conveyors, capable of loading and transporting the crushed rock or coal dust generated during roadheading to downstream transport equipment.

[0004] The main components of a roadheader / rock bolter include: a cutting unit responsible for cutting the roadway; a bolting machine used to drill holes in the roadway wall and install bolts; a loading mechanism to load the gravel or coal dust generated during the tunneling process into a conveyor; a conveyor to transport the loaded material to the subsequent transport equipment; a traveling mechanism that enables the roadheader / rock bolter to move within the roadway; and a hydraulic system that provides power to all components of the roadheader / rock bolter.

[0005] Currently, during underground operation, roadheader-anchor machines need to replace the appropriate anchor bolts according to different rock materials. Manual installation and removal of anchor bolts underground is inconvenient; therefore, there is a need for an underground roadheader-anchor machine with a quick installation and removal mechanism. Utility Model Content
