Shaft hoisting operations are a key link in ensuring the progress of various engineering projects, operation and maintenance efficiency, and operational safety. The hoisting mechanism inside the shaft is a dedicated core piece of equipment for shaft hoisting operations, and its performance directly determines the safety, stability, and efficiency of shaft hoisting operations.

Rollers are installed on all four legs of the gantry, and each roller is driven by a drive motor. This patent proposes a vertical shaft construction hoisting device that can achieve both vertical lifting and horizontal movement, making the hoisting equipment easy and flexible to move. It also avoids the problem of the hoisting equipment being unable to move during shaft blasting, preventing damage and safety accidents. Furthermore, it facilitates the movement of the hoisting equipment to the maintenance site for repairs, reducing safety accidents and accelerating construction efficiency.

[0004] The above technical solution can realize vertical lifting and horizontal movement, making the lifting equipment easy and flexible to move. It avoids the problem of the lifting equipment being unable to move when the shaft is being blasted, and makes it convenient to move the lifting equipment to the maintenance site for maintenance. However, if the winding machine is damaged, the device may cause the hoisting platform to fall, resulting in damage or personnel injury. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hoisting and lifting mechanism for use in vertical shafts and its application method, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hoisting and lifting mechanism for a vertical shaft, comprising a support beam, a base plate, a shaft opening, a fixed frame, a winding machine, a first support plate, a rotating shaft, a winding cable, a lifting plate, and a connecting frame. The base plate is fixedly connected to the bottom of the support beam, the shaft opening is fixedly connected to the inner wall of the base plate, the fixed frame is slidably connected to the inner wall of the support beam, the winding machine is disposed on the top of the fixed frame, the first support plate is fixedly connected to the top of the fixed frame, the rotating shaft is rotatably connected to the inner wall of the first support plate, the winding cable is disposed on the surface of the winding machine, the lifting plate is fixedly connected to the bottom of the winding cable, and the connecting frame is fixedly connected to the left side of the first support plate. The hoisting and lifting mechanism for the vertical shaft further includes: A fall arrestor designed to prevent emergency falls is located on the right side of support plate one. The fall protection mechanism includes a threaded rod, a grooved ring, a speed detector, a U-shaped plate, an arc groove, and a brake disc. A dual-axis motor is fixedly connected to the front of the connecting frame, and a threaded rod is fixedly connected to the output end of the dual-axis motor. A grooved ring is fixedly connected to the circumferential surface of the rotating shaft, and a speed detector is fixedly connected to the bottom of the connecting frame. A U-shaped plate is threadedly connected to the circumferential surface of the threaded rod, and an arc groove is fixedly connected to the left side of the U-shaped plate. A brake disc is fixedly connected to the circumferential surface of the rotating shaft. During the hoisting and lifting operation, the arc groove will contact the brake disc as it moves, thereby braking the brake disc and using friction to further lock the sliding of the winding cable, directly preventing the lifting plate and load from falling due to gravity. This avoids the fall accident caused by the failure of the traditional single protection that relies solely on the winding mechanism for braking, and improves the stability and safety of the device during use. A stabilizing mechanism, used to improve the stability of the lifting platform during descent, is installed on the inner wall of the lifting platform; A vibration damping mechanism, used to reduce vibration during the descent of the lifting platform, is located at the bottom of the lifting platform.

[0007] The anti-fall mechanism also includes a pulley, a rotating rod, an L-shaped plate, a stop bar, and a pressure plate. The pulley is fixedly connected to the circumferential surface of the rotating shaft. The rotating rod is rotatably connected to the inner wall of the connecting frame via a torsion spring. The L-shaped plate is fixedly connected to the top of the U-shaped plate. The stop bar is fixedly connected to the circumferential surface of the rotating rod. The pressure plate is fixedly connected to the circumferential surface of the rotating rod. During the braking process of the coil, the pressure plate rotates and contacts the coil, further fixing the position of the coil and improving the braking effect of the coil. This presses the coil inside the pulley, preventing it from loosening and jumping out of the groove. At the same time, it further locks the coil, forming a double protection to prevent the lifting plate from falling, thereby significantly improving the safety and reliability of the equipment operation.

[0008] The surface of the U-shaped plate is slidably connected to the inner wall of the connecting frame, and the surface of the winding wire is in contact with the inner wall of the pulley.

[0009] The stabilizing mechanism includes a second rotating rod, a V-shaped plate, and a rotating wheel. The second rotating rod is rotatably connected to the inner wall of the lifting plate via a torsion spring. The V-shaped plate is fixedly connected to the circumferential surface of the second rotating rod, and the rotating wheel is rotatably connected to the inner wall of the V-shaped plate. During the downward movement of the lifting plate, the rotating wheel will contact the inner wall of the well opening. At this time, the V-shaped plate will automatically adjust and rotate according to the diameter of the well opening, thereby simplifying the equipment installation and commissioning process, shortening the construction preparation time, and avoiding safety hazards such as lifting plate swaying and collision with the well wall caused by manual adjustment errors. It can also directly limit the lateral displacement and torsional freedom of the lifting plate, eliminate the risk of platform swaying caused by load eccentricity, airflow disturbance, and sudden speed changes during the descent of the lifting mechanism, and ensure operational stability.

[0010] The stabilizing mechanism also includes a limiting ring, a fixed block, an elastic rod, an inclined block, and a multi-faceted block. The limiting ring is fixedly connected to the circumferential surface of the rotating rod, the fixed block is fixedly connected to the bottom of the lifting plate, the elastic rod is slidably connected to the inner wall of the fixed block by a spring, the inclined block is fixedly connected to the left side of the elastic rod, and the multi-faceted block is fixedly connected to the circumferential surface of the limiting ring. During the descent of the lifting plate, the rotating rod can be limited, preventing the V-shaped plate from shifting due to vibration and impact during descent. This ensures that the rotating wheel always maintains stable contact with the inner wall of the wellhead, continuously playing an anti-sway guiding role, and greatly improving the versatility and scene adaptability of the lifting mechanism.

[0011] The surface of the multifaceted block is in contact with the surface of the inclined block, and the bottom of the inclined block is slidably connected to the inner wall of the fixed block.

[0012] The vibration damping mechanism includes a second support plate, a sliding column, a long plate, a second elastic rod, a straight plate, a second U-shaped plate, a third support plate, and a push plate. The second support plate is fixedly connected to the top of the V-shaped plate, the second U-shaped plate is fixedly connected to the bottom of the lifting plate, the sliding column is slidably connected to the inner wall of the second U-shaped plate via a spring, and the long plate is fixedly connected to the top of the lifting plate. During the adaptation process to the shaft wall, it pushes the items placed on the surface of the lifting plate to move towards the center, thereby eliminating the risk of tilting and twisting of the lifting plate caused by load eccentricity, ensuring balanced force during the lifting process, improving operational stability, and eliminating the need for manual intervention to adjust the placement of items, simplifying the hoisting operation process, reducing the labor intensity of operators, and improving the efficiency and automation level of hoisting operations in the shaft. The second elastic rod is slidably connected to the inner wall of the long plate via a spring, the straight plate is fixedly connected to the left side of the second elastic rod, the third support plate is fixedly connected to the bottom of the sliding column, and the push plate is fixedly connected to the right side of the second elastic rod.

[0013] The top of the lifting plate is in contact with the bottom of the push plate, and the right side of the second support plate is in contact with the left side of the straight plate. During the process of the lifting plate falling to the bottom of the well, it can absorb the impact load of the lifting plate touching the bottom at the moment of impact, avoid structural deformation and weld cracking caused by rigid collision between the lifting plate and the bottom of the well, extend the service life of the lifting mechanism, at the same time attenuate the impact of the bottom vibration on the hoisted items, prevent precision equipment and fragile components from precision failure and damage due to impact, and ensure the integrity of the hoisted items.

[0014] A method for using a hoisting and lifting mechanism in a vertical shaft includes the following steps: Step 1: During the hoisting and lifting operation, the winding machine will start and rotate, which will drive the winding to unwind and wind up. During the winding and winding process, the friction will drive the pulley to rotate, which will drive the rotating shaft to rotate. During the rotation of the rotating shaft, the grooved ring will rotate, and then the winding will pull the lifting plate to rise or fall. Step 2: When the speed sensor detects that the speed of the grooved ring is abnormally fast, the speed sensor will send an electrical signal to the dual-axis motor. At this time, the dual-axis motor starts and drives the threaded rod to rotate. The rotation of the threaded rod will drive the U-shaped plate to move to the left through the threaded groove on the surface. The movement of the U-shaped plate to the left will drive the arc groove to move to the left. During the movement of the arc groove, it will contact the brake disc, thereby braking the brake disc. Step 3: During the braking process of the coil, the U-shaped plate moves to the left, which will drive the L-shaped plate to move to the left. During the leftward movement of the L-shaped plate, it will come into contact with the stop bar and push the stop bar to rotate through the thrust. The rotation of the stop bar will drive the rotating rod to rotate. Step 4: When the rotating rod rotates, it will cause the pressure plate to rotate as well. The rotating pressure plate will come into contact with the winding wire and further fix the position of the winding wire, thereby improving the braking effect of the winding wire.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, during the hoisting and lifting process, the arc-shaped groove will contact the brake disc as it moves, thereby braking the brake disc and using friction to further lock the sliding of the winding coil. This directly prevents the lifting plate and load from falling due to gravity, avoiding the fall accident caused by the failure of the single protection that relies solely on the winding mechanism for braking in traditional methods. This improves the stability and safety of the device during use. During the braking process of the winding coil, the pressure plate rotates and contacts the winding coil, further fixing the position of the winding coil and improving the braking effect. This presses the winding coil into the inside of the pulley, preventing it from loosening and jumping out of the groove. At the same time, it further locks the winding coil, forming a double protection to prevent the lifting plate from falling, thereby significantly improving the safety and reliability of the equipment operation.

[0016] 2. In this invention, during the downward movement of the lifting plate, the rotating wheel will contact the inner wall of the well opening. At this time, the V-shaped plate will automatically adjust and rotate according to the diameter of the well opening, thereby simplifying the equipment installation and commissioning process, shortening the construction preparation time, and avoiding safety hazards such as lifting plate swaying and collision with the well wall caused by manual adjustment errors. It can also directly limit the lateral displacement and torsional freedom of the lifting plate, eliminate the risk of platform swaying caused by load eccentricity, airflow disturbance, and sudden speed changes during the descent of the lifting mechanism, ensure operational stability, and prevent components from colliding with the vertical shaft wall, thereby improving the safety of hoisting operations in the vertical shaft. During the descent of the lifting plate, the rotating rod can be limited to prevent the V-shaped plate from displacing due to vibration and impact during the descent, ensuring that the rotating wheel always maintains stable contact with the inner wall of the well opening, continuously playing an anti-sway guiding role, and greatly improving the versatility and scene adaptability of the lifting mechanism.

[0017] 3. In this invention, during the adaptation process to the well wall, the items placed on the surface of the lifting plate are pushed towards the center, thereby eliminating the hidden dangers of tilting and twisting of the lifting plate caused by load eccentricity, ensuring balanced force during the lifting process, improving operational stability, and eliminating the need for manual intervention to adjust the placement of items, simplifying the hoisting operation process, reducing the labor intensity of operators, and improving the efficiency and automation level of hoisting operations in the shaft. During the process of the lifting plate falling to the bottom of the well, it can absorb the impact load of the lifting plate touching the bottom at the moment of contact, avoiding structural deformation and weld cracking caused by rigid collision between the lifting plate and the bottom of the well, extending the service life of the lifting mechanism, and at the same time attenuating the impact of the bottom-touching vibration on the hoisted items, preventing precision equipment and fragile components from precision failure and damage due to impact, and ensuring the integrity of the hoisted items.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please see Figures 1-7 One embodiment of the present invention is a hoisting and lifting mechanism in a vertical shaft, comprising a support beam 1, a base plate 2, a shaft opening 3, a fixed frame 4, a winding machine 5, a support plate 6, a rotating shaft 7, a winding 8, a lifting plate 9, and a connecting frame 10. The base plate 2 is fixedly connected to the bottom of the support beam 1, the shaft opening 3 is fixedly connected to the inner wall of the base plate 2, the fixed frame 4 is slidably connected to the inner wall of the support beam 1, the winding machine 5 is disposed on the top of the fixed frame 4, the support plate 6 is fixedly connected to the top of the fixed frame 4, the rotating shaft 7 is rotatably connected to the inner wall of the support plate 6, the winding 8 is disposed on the surface of the winding machine 5, the lifting plate 9 is fixedly connected to the bottom of the winding 8, and the connecting frame 10 is fixedly connected to the left side of the support plate 6. The hoisting and lifting mechanism in the vertical shaft further includes: A fall arrestor designed to prevent emergency falls is located on the right side of support plate 6. The fall protection mechanism includes a threaded rod 12, a grooved ring 13, a speed detector 14, a U-shaped plate 15, an arc groove 16, and a brake disc 17. A dual-axis motor 11 is fixedly connected to the front of the connecting frame 10. The output end of the dual-axis motor 11 is fixedly connected to the threaded rod 12. The circumferential surface of the rotating shaft 7 is fixedly connected to the grooved ring 13. The bottom of the connecting frame 10 is fixedly connected to the speed detector 14. The circumferential surface of the threaded rod 12 is threadedly connected to the U-shaped plate 15. The left side of the U-shaped plate 15 is fixedly connected to the arc groove 16. The circumferential surface of the rotating shaft 7 is fixedly connected to the brake disc 17. A stabilizing mechanism 23 for improving the stability of the lifting plate 9 during descent is provided on the inner wall of the lifting plate 9; A vibration damping mechanism 24, used to reduce vibration during the descent of the lifting plate 9, is located at the bottom of the lifting plate 9.

[0022] In this embodiment, it should be noted that the speed sensor 14 is used to detect the rotational speed of the groove ring 13 and determine whether the winding 8 is in a detached state.

[0023] In this embodiment, during the hoisting and lifting operation, the winding machine 5 starts and rotates, which in turn drives the winding cable 8 to wind up and unwind. During the winding and unwinding process, the winding cable 8 drives the pulley 18 to rotate through friction. The rotation of the pulley 18 drives the rotating shaft 7 to rotate, which in turn drives the grooved ring 13 to rotate. Subsequently, the winding cable 8 pulls the lifting plate 9 to rise or fall. When the speed sensor 14 detects that the rotation speed of the grooved ring 13 is abnormally high, which may indicate a malfunction in the winding machine 5, the speed sensor 14 will detect the rotation speed of the grooved ring 13 and then send an electrical signal to the dual shaft. Motor 11, at this time, the dual-shaft motor 11 starts and drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 will drive the U-shaped plate 15 to move to the left through the threaded groove on the surface. The movement of the U-shaped plate 15 to the left will drive the arc groove 16 to move to the left. During the movement of the arc groove 16, it will contact the brake disc 17, thereby braking the brake disc 17 and using friction to further lock the slippage of the winding 8, directly preventing the lifting plate 9 and the load from falling due to gravity. This avoids the fall accident caused by the failure of the single protection that relies solely on the braking of the winding machine 5, and improves the stability and safety of the device during use.

[0024] The fall arrestor also includes a pulley 18, a rotating rod 19, an L-shaped plate 20, a stop bar 21, and a pressure plate 22. The pulley 18 is fixedly connected to the circumferential surface of the rotating shaft 7. The rotating rod 19 is rotatably connected to the inner wall of the connecting frame 10 via a torsion spring. The L-shaped plate 20 is fixedly connected to the top of the U-shaped plate 15. The stop bar 21 is fixedly connected to the circumferential surface of the rotating rod 19. The pressure plate 22 is fixedly connected to the circumferential surface of the rotating rod 19. The surface of the U-shaped plate 15 is slidably connected to the inner wall of the connecting frame 10. The surface of the winding cable 8 is in contact with the inner wall of the pulley 18.

[0025] During the braking process of the winding 8, the U-shaped plate 15 moves to the left, which in turn drives the L-shaped plate 20 to move to the left. During the leftward movement of the L-shaped plate 20, it comes into contact with the stop rod 21 and pushes the stop rod 21 to rotate. The rotation of the stop rod 21 drives the rotating rod 19 to rotate, which in turn drives the pressure plate 22 to rotate. The rotation of the pressure plate 22 brings into contact with the winding 8 and further fixes the position of the winding 8, improving the braking effect of the winding 8. This presses the winding 8 into the inside of the pulley 18, preventing it from loosening and jumping out of the groove. At the same time, it further locks the winding 8, forming a double protection to prevent the lifting plate 9 from falling, thereby significantly improving the safety and reliability of the equipment operation.

[0026] Example 2: Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the stabilizing mechanism 23 includes a second rotating rod 231, a V-shaped plate 232 and a rotating wheel 233. The second rotating rod 231 is rotatably connected to the inner wall of the lifting plate 9 by a torsion spring. The V-shaped plate 232 is fixedly connected to the circumferential surface of the second rotating rod 231, and the rotating wheel 233 is rotatably connected to the inner wall of the V-shaped plate 232.

[0027] In this embodiment, during the downward movement of the lifting plate 9, the lifting plate 9 will drive the rotating rod 231 to move downward. The downward movement of the rotating rod 231 will drive the V-shaped plate 232 to move downward. The downward movement of the V-shaped plate 232 will drive the rotating wheel 233 to move downward. The rotating wheel 233 will contact the inner wall of the well opening 3. At this time, the V-shaped plate 232 will automatically adjust and rotate according to the diameter of the well opening 3, thereby simplifying the equipment installation and debugging process, shortening the construction preparation time, and avoiding safety hazards such as the lifting plate 9 swinging or colliding with the well wall caused by manual adjustment errors. At this time, the torsion spring set on the surface of the rotating rod 231 will drive the rotating rod 231 to rotate in the opposite direction, so that the rotating wheel 233 can be tightly attached to the inner wall of the well opening 3. This can directly restrict the lateral displacement and torsional freedom of the lifting plate 9, eliminate the risk of platform swing caused by load eccentricity, airflow disturbance, and sudden speed change during the descent of the lifting mechanism, ensure operational stability, and avoid collision between components and the vertical shaft wall, thereby improving the safety of hoisting operations in the vertical shaft.

[0028] The stabilizing mechanism 23 also includes a limiting ring 234, a fixing block 235, an elastic rod 236, an inclined block 237, and a multi-faceted block 238. The limiting ring 234 is fixedly connected to the circumferential surface of the rotating rod 231. The fixing block 235 is fixedly connected to the bottom of the lifting plate 9. The elastic rod 236 is slidably connected to the inner wall of the fixing block 235 by a spring. The inclined block 237 is fixedly connected to the left side of the elastic rod 236. The side of the inclined block 237 near the multi-faceted block 238 is set as an inclined surface. The circumferential surface of the limiting ring 234 is fixedly connected to the multi-faceted block 238. The side of the multi-faceted block 238 near the inclined block 237 is set as an inclined surface. The surface of the multi-faceted block 238 is in contact with the surface of the inclined block 237. The bottom of the inclined block 237 is slidably connected to the inner wall of the fixing block 235.

[0029] During the descent of the lifting plate 9, the rotation of the second rotating rod 231 causes the limiting ring 234 to rotate. The rotation of the limiting ring 234 causes the multi-faceted block 238 to rotate. During the rotation of the multi-faceted block 238, it comes into contact with the inclined surface of the inclined block 237 and forces the inclined block 237 to move to the right through the squeezing force. The movement of the inclined block 237 to the right causes the first elastic rod 236 to move to the right. During the movement of the inclined block 237 to the right, it compresses the spring on the surface of the first elastic rod 236. When the multi-faceted block 238 passes the inclined block 237, the first elastic rod 236 will move the inclined block 236 through the spring force. When block 237 moves to the left, when the rotating rod 231 rotates to the appropriate angle, the rotating rod 231 will reverse through the torsion spring, which will drive the limiting ring 234 to reverse. The reversal of the limiting ring 234 will drive the multifaceted block 238 to reverse. The reversal of the multifaceted block 238 will contact the bottom of the inclined block 237, thereby limiting the rotating rod 231 and preventing the V-shaped plate 232 from shifting due to vibration and impact during the descent. This ensures that the rotating wheel 233 always maintains stable contact with the inner wall of the wellhead 3, continuously playing an anti-sway guiding role, which can greatly improve the versatility and scene adaptability of the lifting mechanism.

[0030] Example 3: Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the vibration damping mechanism 24 includes a second support plate 241, a sliding column 242, a long plate 243, a second elastic rod 244, a straight plate 245, a second U-shaped plate 246, a third support plate 247, and a push plate 248. The second support plate 241 is fixedly connected to the top of the V-shaped plate 232, the second U-shaped plate 246 is fixedly connected to the bottom of the lifting plate 9, the sliding column 242 is slidably connected to the inner wall of the second U-shaped plate 246 by a spring, the long plate 243 is fixedly connected to the top of the lifting plate 9, the second elastic rod 244 is slidably connected to the inner wall of the long plate 243 by a spring, the straight plate 245 is fixedly connected to the left side of the second elastic rod 244, the third support plate 247 is fixedly connected to the bottom of the sliding column 242, and the push plate 248 is fixedly connected to the right side of the second elastic rod 244.

[0031] During the adaptation process to the shaft wall, the rotation of the V-shaped plate 232 will drive the rotation of the second support plate 241. The rotation of the second support plate 241 will squeeze the left side of the straight plate 245, causing it to move to the right. The movement of the straight plate 245 will drive the second elastic rod 244 to move synchronously. The movement of the second elastic rod 244 will drive the push plate 248 to move to the right, and compress the spring on the surface of the second elastic rod 244 during the movement. At this time, the push plate 248 will push the items placed on the surface of the lifting plate 9 to move towards the center, thereby eliminating the hidden dangers of tilting and twisting of the lifting plate 9 caused by load eccentricity, ensuring that the force is balanced during the lifting of the lifting plate 9, improving the stability of operation, and eliminating the need for manual intervention to adjust the placement of items, simplifying the hoisting operation process, reducing the labor intensity of operators, and improving the efficiency and automation level of hoisting operations in the shaft.

[0032] The top of the lifting plate 9 is in contact with the bottom of the push plate 248, and the right side of the support plate 241 is in contact with the left side of the straight plate 245.

[0033] During the process of the lifting plate 9 falling to the bottom of the well, the downward movement of the lifting plate 9 will drive the U-shaped plate 246 to move downward, the downward movement of the U-shaped plate 246 will drive the sliding column 242 to move downward, and the downward movement of the sliding column 242 will drive the support plate 247 to move downward. During the downward movement of the support plate 247, it will generate a squeezing force with the ground. At this time, the U-shaped plate 246 will continue to move downward relative to the sliding column 242 and will compress the spring on the surface of the sliding column 242, thereby absorbing the impact load of the lifting plate 9 at the moment of contact with the bottom. This avoids structural deformation and weld cracking caused by the rigid collision between the lifting plate 9 and the bottom of the well, extends the service life of the lifting mechanism, and at the same time attenuates the impact of the bottom-contact vibration on the hoisted items, prevents precision equipment and fragile components from failing or breaking due to impact, and ensures the integrity of the hoisted items.

[0034] Furthermore, it should be noted that this application may also include a power supply device and a processor. The power supply device supplies power to the dual-axis motor 11, the winding machine 5, the speedometer 14, etc., and the processor controls the dual-axis motor 11, the winding machine 5, and the speedometer 14. As an example, the power supply device may be a battery pack or municipal power supply equipment, and the processor may be an existing device. This embodiment will not elaborate further. In this embodiment, the electrical connection of each device adopts a conventional continuous connection method.

[0035] Example 4: In addition, based on Embodiments 1, 2, and 3, this embodiment also provides a method for using a hoisting mechanism in a vertical shaft, including the following steps: Step 1: During the hoisting and lifting operation, the winding machine 5 will start and rotate, which will drive the winding 8 to wind up and down. During the winding and unwinding process, the winding 8 will drive the pulley 18 to rotate through friction. The rotation of the pulley 18 will drive the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, the grooved ring 13 will rotate. Then the winding 8 will pull the lifting plate 9 to rise or fall. Step 2: When the speed sensor 14 detects that the rotation speed of the groove ring 13 is abnormally fast, the speed sensor 14 will send an electrical signal to the dual-axis motor 11. At this time, the dual-axis motor 11 starts and drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 will drive the U-shaped plate 15 to move to the left through the threaded groove on the surface. The movement of the U-shaped plate 15 to the left will drive the arc groove 16 to move to the left. During the movement of the arc groove 16, it will contact the brake disc 17, thereby braking the brake disc 17. Step 3: During the braking process of the winding 8, the U-shaped plate 15 moves to the left, which will drive the L-shaped plate 20 to move to the left. During the leftward movement of the L-shaped plate 20, it will come into contact with the stop bar 21 and push the stop bar 21 to rotate through the thrust. The rotation of the stop bar 21 will drive the rotating rod 19 to rotate. Step 4: Rotating the lever 19 will cause the pressure plate 22 to rotate. The rotating pressure plate 22 will come into contact with the winding 8 and further fix the position of the winding 8, thereby further improving the braking effect of the winding 8.
