Description

Technical Field

[0001] The present invention belongs to the technical field of building vertical transportation, and particularly relates to a super high-rise building anti-speed-drop transportation device. Background Art

[0002] The super high-rise building transportation device mainly refers to a system for vertically transporting personnel and goods in high-rise or super high-rise buildings, which mainly consists of a car, a counterweight, a traction machine, a traction wheel, a traction rope, a guide rail, a speed limiter, a safety clamp, a buffer, and a control system. Among them, the traction rope generally refers to a super-strength steel cable, which connects the car and the counterweight and bypasses the traction wheel. The traction machine mainly refers to a permanent magnet synchronous motor that drives the traction wheel to rotate to realize the up and down movement of the car. In the prior art, the way to prevent the super high-rise building transportation device from stalling is generally to monitor the speed of the car through the speed limiter. Once the speed of the car exceeds the set safety limit value, the speed limiter will trigger the safety clamp to clamp the guide rail, prevent the car from accelerating further, and quickly brake the car to prevent it from falling. However, there will be a problem that when the speed limiter triggers the safety clamp to clamp the guide rail, it will brake the car, making the car no longer move up and down. To release the brake, professional personnel are required to operate. And in the super high-rise building transportation system, there is also a risk of the safety clamp failing.

[0003] The Chinese patent document with the publication number of CN110422802A proposes an anti-speed-drop device at high altitude. By setting a first speed-drop mitigation wheel and a second speed-drop mitigation wheel between the traction ropes, when the force generated by the first speed-drop mitigation wheel due to gravitational acceleration is too large and the tooth leaves rotate too fast, the liquid oil in the oil chamber can be impacted to the siphon pipe. Using the principle of siphon, the oil in the oil chamber can be quickly guided to the second speed-drop mitigation wheel. The rotation of the tooth leaves in the second speed-drop mitigation wheel contacts the liquid oil to further offset the gravitational acceleration and reduce the rotation speed of the second speed-drop wheel to resist stalling to solve the above technical problems. However, the action mode of the buffer wheel determines that its buffering effect may have a lag phenomenon, that is, when the stalling phenomenon occurs, adjusting through the buffer wheel may have missed the best opportunity.

[0004] Therefore, the present invention proposes a super high-rise building anti-speed-drop transportation device to solve the problem of lag in the effect of preventing and adjusting the traction lift stalling through the buffer wheel in the prior art. By improving the design of the top structure of the car, it is made to cooperate with the guide rail to deform when stalling, increasing the friction force with the guide rail and then gradually reducing the speed of the car, providing an additional anti-stall safety response mechanism for the super high-rise building transportation device. When stalling, the speed is reduced to ensure that the car runs within a certain speed range and moves to the nearest target height for normal braking by the control system, minimizing the stalling risk. Using it in combination with the safety clamp can provide an additional second layer of protection for the super high-rise building transportation device, further enhancing the safety of the super high-rise building transportation device.

[0034] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some, but not all, of the embodiments of the present invention, and are only used to explain the embodiments of the present invention, rather than limiting the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] Please refer to Figures 1 to 16, the present invention provides a technical solution: a super high-rise building anti-speed-drop transportation device, including a transportation installation well 1. At the top of the transportation installation well 1, a traction component 11 and a speed limiter component 12 are provided. In the middle of the transportation installation well 1, a car 13 and a counterweight component 14 are provided. On the rear side surface of the car 13, a safety gear component 15 is provided. In this embodiment, the traction component 11 is mainly composed of a traction machine, a traction wheel, and traction ropes. Among them, the traction ropes are three groups of ultra-strength steel cables, connecting the car 13 and the counterweight component 14 and bypassing the traction wheel. The traction machine is a permanent magnet synchronous motor that drives the traction wheel to rotate to realize the up and down movement of the car. The speed limiter component 12 mainly functions to monitor the running speed of the car 13. On both sides behind the transportation installation well 1, counterweight guide rails are provided. In the middle of the transportation installation well 1, car guide rails are provided. The safety gear component 15 is installed on the rear side of the car 13. When the car 13 completely stalls, the safety gear component 15 starts to clamp the car guide rails to make the car 13 brake emergently. At the bottom of the transportation installation well 1, a buffer combination is provided. On one side at the top of the transportation installation well 1, a control system component is provided; a speed reduction component 2 is provided outside the car 13. On both sides of the car 13, auxiliary limit guide rail frames 3 are provided. On the inner surface of the auxiliary limit guide rail frames 3, triangular guide rails 31 are symmetrically and fixedly installed. On the inner surface of the triangular guide rails 31, speed limit grooves 311 adapted to the speed reduction wing plates 262 are provided. In the middle of the inner surface of the auxiliary limit guide rail frames 3, an internal U-shaped guide rail 32 adapted to the speed reduction wheels 251 is fixedly installed. In this embodiment, the auxiliary limit guide rail frames 3 mainly function to install the triangular guide rails 31 and the internal U-shaped guide rail 32. The internal U-shaped guide rail 32 mainly cooperates with the speed reduction movable block 25 to make the speed reduction wheels 251 squeeze and deform to increase the friction force. The triangular guide rails 31 mainly cooperate with the trapezoidal speed reduction wing blocks 26 to make the speed reduction wing plates 262 squeeze and deform to increase the friction force; in the middle of the traction rope mounting frame 22, an oil cylinder one 23 and an oil cylinder two 24 are fixedly installed. At one end of the oil cylinder one 23 and the oil cylinder two 24, a driving device is provided. Inside the oil cylinder one 23, a piston one 231 is movably installed. One end of the piston one 231 is fixedly connected to the side surface of the speed reduction movable block 25. The speed reduction component 2 includes a car mounting frame 21 fixedly installed on the outer side surface of the car 13. At the top of the car mounting frame 21, a traction rope mounting frame 22 is fixedly installed. On both sides of the traction rope mounting frame 22 close to the auxiliary limit guide rail frames 3, grooves one 221 are symmetrically provided respectively. On both sides of the inner surface of the traction rope mounting frame 22, speed reduction movable blocks 25 are symmetrically and movably installed. On the inner surface of the traction rope mounting frame 22, a chute one adapted to the speed reduction movable block 25 is provided. Inside the chute one, a reset spring telescopic rod 223 is provided. Inside one side of the speed reduction movable block 25 close to the groove one 221, a speed reduction wheel 251 is movably installed;In this embodiment, the traction rope mounting bracket 22 mainly functions to mount the speed reduction movable block 25, the first oil cylinder 23 and the second oil cylinder 24. The car mounting bracket 21 is used to fix the traction rope mounting bracket 22 to the top of the car 13. An installation bracket fixed to the traction rope is provided above the traction rope mounting bracket 22. When the speed of the car 13 is too fast and reaches a predetermined speed, the first oil cylinder 23 and the second oil cylinder 24 quickly respond under the control of the control system. Oil is supplied to the inside of the first oil cylinder 23, causing the piston 231 to push out the speed reduction movable block 25, and the reset spring telescopic rod 223 is squeezed. At this time, the side surface of the speed reduction wheel 251 is squeezed against the side wall of the built-in U-shaped guide rail 32, and the speed reduction wheel 251 will deform, increasing the friction between the speed reduction wheel 251 and the built-in U-shaped guide rail 32, thereby reducing the speed of the car 13.;

[0037] Embodiment 2

[0038] Please refer to Figures 1 to 16, on the basis of the first embodiment, this embodiment further proposes that speed-limiting clamping plates 252 are symmetrically arranged on both sides of the speed-reducing wheel 251. One end of each speed-limiting clamping plate 252 is fixedly installed with a triangular tail plate 2521. A bidirectional telescopic rod 2522 is fixedly installed between the side surfaces of the triangular tail plates 2521. A friction ring one 2511 is fixedly installed on the side surface of the speed-reducing wheel 251. A friction ring two 2523 is fixedly installed on the side surface of the speed-limiting clamping plate 252 close to the friction ring one 2511. Limited extrusion frames 222 are symmetrically and fixedly installed on the inner sides of both ends of the traction rope mounting frame 22. A chute two adapted to the limited extrusion frame 222 is provided on the side wall of the speed-reducing movable block 25. The side surface of the limited extrusion frame 222 is in contact with the side surface of the triangular tail plate 2521. Deformable rolling plates 2512 are evenly distributed on the outer surface of the speed-reducing wheel 251. A movable connecting rod 2513 is fixedly installed on the outer surface of the speed-reducing wheel 251. The upper ends of the movable connecting rods 2513 are movably connected to the inner side surfaces of the movable connecting rods 2513 respectively; in this embodiment, both ends of the rotating shaft of the speed-reducing wheel 251 are rotatably connected to the side wall of the speed-reducing movable block 25. An activity groove adapted to the rotating shaft of the speed-reducing movable block 25 is provided on the side wall of the limited extrusion frame 222. First, when the speed-reducing movable block 25 is pushed out by the piston one 231, the triangular tail plate 2521 will gradually increase its contact with the limited extrusion frame 222. Due to the design of the mating triangular blocks of the limited extrusion frame 222 and the triangular tail plate 2521, the triangular tail plate 2521 is squeezed inward, causing the friction ring two 2523 to come into extrusion contact with the friction ring one 2511 on the outside of the speed-reducing wheel 251, increasing the rotational frictional force of the speed-reducing wheel 251 so that the speed-reducing wheel 251 no longer rolls. The bidirectional telescopic rod 2522 serves to movably install the triangular tail plates 2521 on both sides. After the speed-reducing wheel 251 is pushed out, it is squeezed against the side wall of the built-in U-shaped guide rail 32. Since the speed-limiting clamping plate 252 clamps the speed-reducing wheel 251, the speed-reducing wheel 251 does not roll. At this time, combined with the extrusion against the side wall of the built-in U-shaped guide rail 32, the deformable rolling plates 2512 will deform in cooperation with the movable connecting rods 2513 to increase the contact area with the built-in U-shaped guide rail 32. The surface of the deformable rolling plates 2512 is also provided with inclined edges, further increasing the frictional force between the deformable rolling plates 2512 and the built-in U-shaped guide rail 32.

[0039] Embodiment Three

[0040] Please refer to Figures 1 to 16, on the basis of the second embodiment, this embodiment further proposes that trapezoidal speed reduction wing blocks 26 are symmetrically and fixedly installed on both side surfaces of the speed reduction movable block 25. An extrusion inner push block 261 is movably installed inside one side of the trapezoidal speed reduction wing block 26 close to the first groove 221. A reset pad 2611 is arranged between the side surface of the extrusion inner push block 261 and the inner wall of the trapezoidal speed reduction wing block 26. A speed reduction wing plate 262 is arranged on the outer side surface of the trapezoidal speed reduction wing block 26. One end of the speed reduction wing plate 262 is movably installed with a movable frame 2621. The middle of the movable frame 2621 is rotationally connected to the inner wall of the trapezoidal speed reduction wing block 26. The other end of the movable frame 2621 is movably connected to one end of the extrusion inner push block 261. A friction extrusion plate 2622 is movably installed on the side wall of the trapezoidal speed reduction wing block 26. Triangular guide rails 31 are symmetrically and fixedly installed on the inner side surface of the auxiliary limit guide rail frame 3. A speed limit groove 311 adapted to the speed reduction wing plate 262 is opened on the inner side surface of the triangular guide rail 31. An internal U-shaped guide rail 32 adapted to the speed reduction wheel 251 is fixedly installed in the middle of the inner side surface of the auxiliary limit guide rail frame 3; in this embodiment, the trapezoidal speed reduction wing block 26 moves synchronously with the speed reduction movable block 25. After the speed reduction movable block 25 is pushed out, the trapezoidal speed reduction wing block 26 will enter the inside of the triangular guide rail 31. At this time, the extrusion inner push block 261 retracts due to the extrusion with the side wall of the triangular guide rail 31, pushing the movable frame 2621 to rotate to expand the speed reduction wing plate 262 and snap it into the speed limit groove 311, increasing the friction between the trapezoidal speed reduction wing block 26 and the triangular guide rail 31, achieving further reduction of the speed of the car 13. The friction extrusion plate 2622 installed inside the speed reduction wing plate 262 will adaptively move and fit the speed limit groove 311 after the speed reduction wing plate 262 is engaged and extruded with the speed limit groove 311, increasing the contact area of the speed reduction wing plate 262. Similarly, anti-slip ridges are also arranged on the surface of the friction extrusion plate 2622 to further increase the friction force.

[0041] Embodiment Four

[0042] Please refer to Figures 1 to 16 , on the basis of the third embodiment, this embodiment further proposes that an oil delivery pipe 241 is fixedly installed at one end of the second oil cylinder 24. Telescopic sleeves 242 are symmetrically and fixedly installed on both sides of the first oil cylinder 23. One end of the oil delivery pipe 241 is fixedly connected to the side wall of the telescopic sleeve 242. A second piston 243 is movably installed inside the telescopic sleeve 242. A clamping plate 244 is fixedly installed at one end of the second piston 243;

[0043] In this embodiment, the second oil cylinder 24 responds to the control of the control system. Oil is fed into the second oil cylinder 24 and conveyed to the telescopic sleeve 242 through the oil pipeline 241, enabling the second piston 243 to move and push out the clamping plate 244, which contacts and clamps the outer side of the triangular guide rail 31, increasing the frictional force and further reducing the speed of the car 13. It should be noted that the response start speed of the first oil cylinder 23 and the second oil cylinder 24 is lower than the start speed of the safety clamp assembly 15, that is, the first oil cylinder 23 and the second oil cylinder 24 work independently of the safety clamp assembly 15, playing a role of secondary protection. In specific situations, such as when the speed of the car 13 is not significantly reduced after the first oil cylinder 23 and the second oil cylinder 24 are started, or the first oil cylinder 23 and the second oil cylinder 24 are not started in time, and the speed of the car 13 still reaches the response start speed of the safety clamp assembly 15, the safety clamp assembly 15 can still work to perform an emergency brake on the car 13. It should also be noted that after the first oil cylinder 23 and the second oil cylinder 24 are started, the system needs to give feedback. When the speed of the car 13 is reduced to a certain range and runs to the nearest destination height, the control system controls the car 13 to brake normally. At this time, fault troubleshooting and maintenance are required. Then, the first oil cylinder 23 and the second oil cylinder 24 return oil under the control of the control system, and the first piston 231 and the second piston 243 are reset, causing the speed reduction wheel 251 to disengage from the built-in U-shaped guide rail 32, and the trapezoidal speed reduction wing block 26 and the clamping plate 244 to disengage from the triangular guide rail 31, enabling the car 13 to resume normal operation after restarting. The specific reset procedure of the speed reduction movable block 25 is that after the first piston 231 is reset, the speed reduction movable block 25 retreats with the assistance of the reset spring telescopic rod 223, and the triangular tail plate 2521 also retreats. The speed limit clamping plate 252 cancels the clamping of the first friction ring 2511 in cooperation with the bidirectional telescopic rod 2522. Similarly, the trapezoidal speed reduction wing block 26 retreats synchronously with the speed reduction movable block 25, disengages from the triangular guide rail 31, and squeezes the inner push block 261 to reset with the cooperation of the reset pad 2611, causing the friction extrusion plate 2622 to reset and pulling the speed reduction wing plate 262 to recover.

[0044] Embodiment 5

[0045] Please refer to Figures 1 to 16 , on the basis of Embodiment 4, this embodiment also proposes a method for using a speed reduction prevention transportation device for super high-rise buildings, including the following steps:

[0046] Step 1, stall response. The speed limiter assembly 12 monitors the running speed of the car 13. When the speed of the car 13 is too fast and reaches a predetermined speed, the first oil cylinder 23 and the second oil cylinder 24 quickly respond under the control of the control system. Oil is supplied to the inside of the first oil cylinder 23, so that the first piston 231 pushes out the speed reduction movable block 25. The side of the speed reduction wheel 251 is squeezed against the side wall of the built-in U-shaped guide rail 32 and deformed, increasing the friction between the speed reduction wheel 251 and the built-in U-shaped guide rail 32. Oil is supplied to the inside of the second oil cylinder 24 and is conveyed to the telescopic sleeve 242 through the oil pipeline 241, so that the second piston 243 moves to push out the clamping plate 244, which contacts and clamps the outside of the triangular guide rail 31, further increasing the friction and reducing the running speed of the car 13;

[0047] Step 2, normal braking at the nearest destination height. When the speed of the car 13 is reduced to a certain range and it runs to the nearest destination height, the control system controls the car 13 to brake normally. At this time, it is necessary to check for faults and perform repairs. Then, the first oil cylinder 23 and the second oil cylinder 24 return oil under the control of the control system, and the first piston 231 and the second piston 243 both reset, so that the speed reduction wheel 251 disengages from the built-in U-shaped guide rail 32, and the trapezoidal speed reduction wing block 26 and the clamping plate 244 disengage from the triangular guide rail 31, enabling the car 13 to resume normal operation after restarting;

[0048] Step 3, emergency braking. In specific situations, such as when the speed of the car 13 is not significantly reduced after the first oil cylinder 23 and the second oil cylinder 24 are started, or the first oil cylinder 23 and the second oil cylinder 24 do not start in time, and the speed of the car 13 still reaches the response start speed of the safety gear assembly 15, the safety gear assembly 15 can still work to perform emergency braking on the car 13.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
