On the other hand, the distance moved by the diamond wire that stops in time after breaking is greatly reduced, which is convenient for the staff to recover and maintain.

On the one hand, it can provide a certain lubricating medium for the cutting of the diamond wire and the ore, reduce the wear of the diamond wire during cutting, and improve the service life of the diamond wire. On the other hand, when the diamond wire with clean water attached is cutting the ore, the appearance of sparks can be avoided through the attached clean water, thereby avoiding fire and improving the safety of cutting.

[0017] 3.

[0029] When cutting underground, the driving motor 503 drives the first bevel gear 504 to rotate, the first bevel gear 504 drives the second bevel gear 505 to rotate, the second bevel gear 505 drives the two adjusting screws 502 to rotate, the adjusting screws 502 drive the screw seat 501 to move to both sides, and the screw seat 501 drives the auxiliary wheel 7 to move slowly to both sides. As the cutting proceeds, the auxiliary wheel 7 expands outward and keeps the diamond wire rope in a taut state at all times, thereby ensuring the flatness of the ore cutting and improving the cutting quality.

The liquid capsule 409 cooperates with the connecting pipe 405, the telescopic hose 403 and the one-way valve to realize the one-way extraction of clean water in the liquid storage tank 401. The clean water is sprayed out through the nozzle 404 and sprayed on the surface of the diamond wire, so that the surface of the diamond wire is moistened, which can avoid sparks and fires caused by sparks during cutting and improve the safety of cutting.

10. A high-safety cutting method for underground mines, characterized in that: A high-safety mining wire saw for underground use in a mine as claimed in any one of claims 1 to 9, specifically comprising the following steps: S1. A worker drills a hole in the mine area to be cut. After that, the worker passes a diamond wire through the hole and winds it around the driving wheel (8) and the auxiliary wheel (7). The diamond wire is kept in a taut state relative to the driving wheel (8) and the auxiliary wheel (7). The trigger disk (901) is in an untriggered state. The driving device (3) drives the diamond wire to cut the ore through the driving wheel (8) and the auxiliary wheel (7). S2. When the diamond wire breaks accidentally, the diamond wire no longer exerts pressure on the bonding plate (902), and the trigger disk (901) is automatically triggered through transmission. The trigger disk (901) stops the driving device (3) through transmission, and makes the upper friction disk (912) contact the lower friction disk (913). The friction force causes the driving wheel (8) to stop rotating rapidly, causing the diamond wire to quickly lose kinetic energy and stop, thereby avoiding damage to the staff and the working environment; S3, when the driving wheel (8) drives the diamond wire to cut the ore, the tensioning assembly (5) in the mounting frame (6) drives the auxiliary wheel (7) to expand outward and keep the diamond wire in a taut state at all times, thereby ensuring that the diamond wire maintains sufficient cutting force on the ore; S4. During the ore cutting process, the spraying assembly (4) continuously sprays clean water onto the diamond wire rope through transmission, so that the clean water adheres to the surface of the diamond wire rope to avoid sparks during the cutting process.
