[0028] Specifically, in the present embodiment: S1: install the lifting component: First, the main machine assembly 2 and the guide wheel assembly 5 are fixed at the installation position of the mine hoist. The main machine assembly 2 includes a main machine base 201, a winding motor 203, and a winding drum 202, wherein the winding drum 202 is driven by the winding motor 203 and is used to wind and unwind the lifting cable 204. The guide wheel assembly 5 includes a movable guide wheel member 501 and a fixed guide wheel 502, which are installed through a second support base 503. The position of the fixed guide wheel 502 needs to be aligned with the cable connection direction of the cage assembly in the tunnel, and the movable guide wheel member 501 is used to transition the angle between the lifting cable 204 and the winding drum 202, reducing the bending wear. When installing, the height of the fixed guide wheel 502 is adjusted by the threaded lifting cylinder to ensure smooth cable path; Select the installation of the carrier component: according to the type of mine tunnel, inclined or vertical, select the corresponding installation of the cage assembly: inclined installation: select the first cage assembly 3. First, fix the control base 301 on the slope of the tunnel bottom, adjust the inclination angle of the supporting plate 3013 by adjusting the rod 3012, so that the sliding angle of the first cage 302 matches the slope of the tunnel. The lifting cable 204 is connected to the first cage 302 through the guide wheel assembly 5. The top buffer protection 303 is installed on the upper side of the first cage 302, which is used to buffer the impact of falling objects in the inclined way; vertical installation: select the second cage assembly 4. The fixed slide 4022 of the slide rail 402 is installed on the inner wall of the vertical tunnel, and the second cage 401 slides on the fixed slide 4022 through the slide rail 4021 and the pulley 4023.

When lifting heavy load or lowering light load, use conservative speed parameters to reduce cable tension; When lifting light load or lowering heavy load, pay attention to brake control. Automatically reduce speed at the wellhead and well bottom area to reduce cable bending wear at the guide wheel; Tension monitoring and safety response: monitor the tension of the lifting cable 204 through the stress sensor on the movable guide wheel 5014 and the fixed guide wheel 502. If abnormal tension is detected, such as cage jamming, the system will immediately reduce the speed or stop smoothly in an emergency to prevent slipping or rope breaking accidents and protect the rope.

[0029] In the embodiment, the synergistic design of the lifting component and the load-carrying component effectively reduces the rope wear by the arrangement and cooperation of the lifting component and the load-carrying component. The main machine assembly 2 in the lifting component adopts a double-row winding and unwinding lifting main machine, which balances the stress of the lifting cable 204 by symmetric arrangement, avoiding excessive friction at a single point. The load-carrying component is adaptively configured according to the tunnel environment: for inclined tunnels, the first cage assembly 3 adjusts the inclination angle of the first cage 302 by adjusting the base 301, so that part of the gravity is dispersed to the limiting slide 3014 and the pulley, reducing the direct tension of the lifting cable 204; for vertical tunnels, the second cage assembly 4 connects the cable 4031 in an S-shaped arrangement through multiple limiting rollers 4033 in the lifting piece 403, dispersing the cable stress and reducing local wear. In addition, the buffer bottom pad 1 and the top buffer protection piece 303 provide impact buffering and reduce dynamic wear during operation. In cooperation with the S-shaped speed curve control, the acceleration is smooth, further reducing the fatigue loss of the lifting rope. This overall cooperation not only prolongs the service life of the lifting rope and reduces the replacement frequency, but also improves the operation safety and efficiency of the elevator, solving the problems of fast wear and high risk coefficient caused by high load in the background art.

The protection ring 5012 in the movable guide wheel 501 is always attached to the short shaft of the movable guide wheel 5014 through the connecting spring 5013 to provide stable positioning and prevent friction caused by cable jumping or deviation. At the same time, the stress sensors provided on the movable guide wheel 5014 and the fixed guide wheel 502 monitor the cable tension in real time, compare it with the preset curve, and adjust the operating parameters in time to avoid overload wear. This design of the guide wheel assembly not only disperses the bending point stress of the cable, but also reduces the impact and friction through dynamic monitoring and adjustment, thereby prolonging the service life of the lifting cable, reducing maintenance costs and safety risks, and solving the problem of rapid wear of the lifting cable due to long-term friction in the background art.
