Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more particularly to a track-type elevator for use in chimneys. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves along at least two rigid tracks perpendicular to the horizontal plane or at an angle of less than 15° to the vertical. It mainly consists of the following systems: Traction system: The main function of the traction system is to output and transmit power to make the elevator run; Guiding system: The main function of the guiding system is to restrict the freedom of movement of the car and counterweight, ensuring that the car and counterweight can only move up and down along the guide rails; Car; Door system; Weight balancing system; Electrical control system; Safety protection system: Ensures the safe use of the elevator and prevents any accidents that endanger personal safety.

[0003] A search revealed patent application CN201922228661.0: a chimney rail elevator, comprising a chimney body, rigid guide rails, and a lifting system. The lifting system includes a lift, a traction rope, a car, and a guide mechanism. A maintenance platform is provided on the chimney body, and the lift is mounted on the maintenance platform. The guide mechanism is correspondingly positioned to the rigid guide rails, and a straight ladder is provided on the rigid guide rails. The rigid guide rails are connected to the chimney body via reinforcing support plates. This utility model provides a solution that meets national standards and offers a safe rail elevator solution specifically for chimneys; however, it also has some shortcomings:

[0004] For example, if the elevator is an outdoor elevator, during the winter snow season, because the elevator shaft is not enclosed, a large amount of ice and snow will adhere to the traction rope once it snows or freezes. If this ice and snow is not cleared in time, it will cause the elevator traction rope to get stuck when entering the rope wheel groove, causing the wire rope to jump out of the rope groove, which poses a certain safety hazard. In addition, the ice and snow wrapped on the traction rope will also reduce the traction friction coefficient, causing the traction rope to slip and resulting in elevator slippage accidents.

[0005] Therefore, we propose a track-mounted elevator for chimneys. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a track-type elevator for chimneys.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A track-mounted elevator for chimneys includes a track frame, multiple treads, multiple mounting columns, a top frame, a hoist, and an elevator car. The track frame has a continuous H-shaped structure. The multiple treads are sequentially and fixedly connected to the inner wall of the track frame. One end of each mounting column is fixedly connected to the side wall of the track frame. The elevator car is slidably connected to the track frame. The top frame is fixedly connected to the top wall of the track frame. The hoist is fixedly connected to the top frame and is fixedly connected to the elevator car via a cable. Multiple tie rods are fixedly connected to the bottom wall of the top frame. The ends of the tie rods away from the top frame are jointly fixedly connected to a circular box. The top of the circular box has a through hole through which the cable passes. A cleaning mechanism for removing ice and snow from the cable is symmetrically arranged inside the circular box. A drive mechanism for providing power to the cleaning mechanism is symmetrically arranged inside the circular box.

[0009] Furthermore, the cleaning mechanism includes a vertical plate, a bottom block, an L-shaped hole, a storage groove, a scraper, a first wedge block, a limiting groove, a first spring, and a limiting block. The vertical plates are symmetrically fixedly connected to the inner wall of the round box. A bottom block is fixedly connected to one end of each vertical plate away from the inner wall of the round box. An L-shaped hole is opened in the inner wall of the bottom block, and a storage groove is opened in the side wall of the bottom block. The storage groove and the L-shaped hole are connected. A first wedge block is slidably connected inside the L-shaped hole, and a scraper is fixedly connected to one end of the first wedge block.

[0010] Furthermore, a limiting groove is formed in the inner wall of the L-shaped hole, and a first spring is fixedly connected to the inner wall of the limiting groove. The other end of the first spring is fixedly connected to a limiting block, and the limiting block is slidably connected inside the limiting groove. The top wall of the limiting block is fixedly connected to the inner wall of the first wedge block.

[0011] Furthermore, the driving mechanism includes a motor, a rotating shaft, a circular plate, an eccentric shaft, a push rod, a connecting shaft, a slider, a slide block, a first limiting post, a second limiting post, and a sliding block. Two sliding blocks are slidably connected to the side wall of the vertical plate, and the side walls of the two sliding blocks are fixedly connected to the slide block. The side walls of the slide block are respectively provided with a first limiting post and a second limiting post. A slider is slidably connected to the side wall of the slide block, and a connecting shaft is fixedly connected to the side wall of the slider.

[0012] Furthermore, motors are symmetrically fixedly connected to the inner wall of the circular box via fixing rods. Each motor's output end is fixedly connected to a rotating rod. A circular plate is fixedly connected to the end of the rotating rod away from the motor. An eccentric shaft is fixedly connected to the side wall of the circular plate. The eccentric shaft is eccentrically positioned on the side wall of the circular plate. A push rod is rotatably connected to the side wall of the eccentric shaft. The end of the push rod away from the eccentric shaft is rotatably connected to an adjacent connecting shaft.

[0013] Furthermore, the driving mechanism also includes a sliding groove, a second spring, a first cavity, a T-shaped block, a tension spring, a second cavity, a limiting wedge block, a slot, and a connecting pipe. The second limiting post is fixedly connected to the side wall of the slide block. The side wall of the slide block has a sliding groove. The inner wall of the sliding groove is fixedly connected to a second spring. The end of the second spring away from the inner wall of the sliding groove is fixedly connected to the first limiting post. The first limiting post is slidably connected inside the sliding groove.

[0014] Furthermore, the first limiting post has a first cavity on its side wall, a tension spring is fixedly connected to the inner wall of the first cavity, and a T-shaped block is fixedly connected to the other end of the tension spring. The T-shaped block is slidably connected inside the first cavity and slidably connected through the side wall of the first cavity. The vertical plate has a second cavity on its inner wall, and a limiting wedge block is slidably connected through the inner wall of the second cavity. The first cavity is fixedly connected to the adjacent second cavity through a connecting pipe. The slide block has a slot on its side wall, and the limiting wedge block is engaged in the slot. The first cavity, the second cavity, and the connecting pipe are filled with hydraulic oil. The slide block has a wedge-shaped structure.

[0015] Furthermore, the scraper has a semi-circular structure, and the scraper slides against the storage groove. Two temperature sensors are fixedly connected to the inner wall of the circular box, and each temperature sensor is electrically connected to the adjacent motor.

[0016] The present invention has the following advantages:

[0017] 1. Multiple mounting columns are fixedly connected to the side wall of the chimney at the ends away from the track frame. The track frame is installed on the side wall of the chimney, and multiple steps are fixedly connected to the inner wall of the track frame in sequence. On the one hand, the track frame can be supported and fixed to improve its support force. On the other hand, it can be used by users to climb up and down on multiple steps. The hoist drives the elevator car to move vertically along the side wall of the track frame through the cable, thereby achieving the purpose of elevator transportation.

[0018] 2. During the winter snow season, ice and snow often adhere to the cable and freeze. By setting up a structure with an eccentric shaft, a slide block and multiple wedge blocks, the motor is turned on. The output end of the motor drives the rotating rod, the circular plate and the eccentric shaft to move. This causes the connecting shaft to drive the slider to reciprocate on the side wall of the slide block. When the slider moves downward on the side wall of the slide block, it will drive the first wedge block and the scraper to move a certain distance until they come into contact with the side wall of the cable. Then, during the winding or unwinding process, the cable will continuously come into contact with the two scrapers and scrape them. The two scrapers will scrape off the ice and snow that adhere to the side wall of the cable.

[0019] 3. When the slider slides vertically upward on the side wall of the slide block and contacts the T-shaped block on the side wall of the first limiting post, on the one hand, the slider will squeeze the T-shaped block, causing the T-shaped block to slide a distance inside the first cavity to seal and draw the hydraulic oil inside the second cavity into the first cavity, and the limiting wedge block and the slot will disengage. On the other hand, the second limiting post will drive the slide block to slide upward a distance. After the slide block moves upward a distance, it will disengage from the first wedge block. Then, under the tension of the first spring, the limiting block will drive the first wedge block and the scraper to move quickly into the collection groove. Since the scraper side wall and the collection groove slide tightly against each other, the collection groove will clean the ice and snow adhering to the scraper, thereby improving the scraper's cleaning ability.

Detailed Implementation

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Reference Figures 1-6 A track-mounted elevator for chimneys includes a track frame 1, multiple treads 2, multiple mounting columns 3, a top frame 4, a hoist 5, and an elevator car 37. The track frame 1 has a continuous H-shaped structure. The multiple treads 2 are sequentially and fixedly connected to the inner wall of the track frame 1. One end of each mounting column 3 is fixedly connected to the side wall of the track frame 1. The elevator car 37 is slidably connected to the track frame 1. The top frame 4 is fixedly connected to the top wall of the track frame 1. The hoist 5 is fixedly connected to the top frame 4 and is fixedly connected to the elevator car 37 via a cable 6. The bottom wall of the top frame 4 is fixed. Multiple pull rods 7 are connected, and the ends of the multiple pull rods 7 away from the top frame 4 are fixedly connected to a round box 8. The top of the round box 8 has an insertion hole 9, through which a cable 6 passes. Multiple pedals 2 are fixedly connected to the inner wall of the track frame 1 in sequence. On the one hand, the track frame 1 can be fixedly supported, and on the other hand, users can climb up and down on the multiple pedals 2. The hoist 5 is existing technology. It mainly drives the elevator car 37 to move vertically along the side wall of the track frame 1 through the cable 6, thereby achieving the purpose of elevator transportation.

[0029] The inside of the round box 8 is symmetrically equipped with a cleaning mechanism to remove ice and snow from the cable 6;

[0030] The round box 8 has symmetrical drive mechanisms inside that provide power to the cleaning mechanism.

[0031] The cleaning mechanism includes a vertical plate 20, a bottom block 21, an L-shaped hole 10, a storage groove 39, a scraper 13, a first wedge block 12, a limiting groove 30, a first spring 31, and a limiting block 32. The vertical plates 20 are symmetrically fixedly connected to the inner wall of the round box 8. The bottom block 21 is fixedly connected to one end of each vertical plate 20 away from the inner wall of the round box 8. The inner wall of the bottom block 21 has an L-shaped hole 10, and the side wall of the bottom block 21 has a storage groove 39. The storage groove 39 and the L-shaped hole 10 are connected. The first wedge block 12 is slidably connected inside the L-shaped hole 10. The scraper 13 is fixedly connected to one end of the first wedge block 12.

[0032] A limiting groove 30 is formed on the inner wall of the L-shaped hole 10. A first spring 31 is fixedly connected to the inner wall of the limiting groove 30. A limiting block 32 is fixedly connected to the other end of the first spring 31. The limiting block 32 is slidably connected inside the limiting groove 30. The top wall of the limiting block 32 is fixedly connected to the inner wall of the first wedge block 12.

[0033] The drive mechanism includes a motor 11, which has a built-in control circuit to control the rotation state of the motor 11; a rotating rod 14; a circular plate 15; an eccentric shaft 16; a push rod 17; a connecting shaft 18; a slider 19; a slide block 23; a first limiting post 26; a second limiting post 40; and a sliding block 22. Two sliding blocks 22 are slidably connected to the side wall of the vertical plate 20. The two sliding blocks 22 are fixedly connected to the slide block 23 on their side walls. The side wall of the slide block 23 is respectively provided with the first limiting post 26 and the second limiting post 40. A slider 19 is slidably connected to the side wall of the slide seat 23, and a connecting shaft 18 is fixedly connected to the side wall of the slider 19. When the ambient temperature reaches the freezing point, the temperature sensor 38 sends a signal to the motor 11, which is electrically connected to it. The motor 11 is turned on, and the output end of the motor 11 drives the rotating rod 14 to rotate. The rotating rod 14 drives the circular plate 15 to rotate, and the circular plate 15 drives the eccentrically set eccentric shaft 16 to move. Then, the eccentric shaft 16 drives the slider 19 to reciprocate in the vertical direction on the side wall of the slide seat 23 through the connecting shaft 18.

[0034] The inner wall of the circular box 8 is symmetrically fixed with fixed rods. The other end of each fixed rod is fixedly connected with a motor 11. The output end of each motor 11 is fixedly connected with a rotating rod 14. The end of the rotating rod 14 away from the motor 11 is fixedly connected with a circular plate 15. An eccentric shaft 16 is fixedly connected to the side wall of the circular plate 15. The eccentric shaft 16 is eccentrically set on the side wall of the circular plate 15. A push rod 17 is rotatably connected to the side wall of the eccentric shaft 16. The end of the push rod 17 away from the eccentric shaft 16 is rotatably connected to an adjacent connecting shaft 18. When the slider 19 moves downward on the side wall of the slide block 23, the slider 19 will come into contact with the second limiting post 40, and then pass through the second limiting post. 40 drives the slide 23 to move downward a certain distance. The bottom end of the slide 23 will enter the L-shaped hole 10 and slide against the first wedge block 12, thereby pushing the first wedge block 12 to slide a certain distance. At this time, the limiting wedge block 34 will be inserted into the slot 35 to limit the slide 23. The first wedge block 12 will drive the scraper 13 fixedly connected to it to move a certain distance until it just comes into contact with the side wall of the cable 6. Then, during the winding or unwinding process, the cable 6 will continuously scrape against the two scrapers 13. The two scrapers 13 will scrape off the ice and snow adhering to the side wall of the cable 6, eliminating the safety hazards of the elevator.

[0035] The drive mechanism also includes a sliding groove 24, a second spring 25, a first cavity 27, a T-shaped block 29, a tension spring 28, a second cavity 33, a limiting wedge block 34, a slot 35, and a connecting pipe 36. The second limiting post 40 is fixedly connected to the side wall of the slide block 23. The side wall of the slide block 23 is provided with a sliding groove 24. The inner wall of the sliding groove 24 is fixedly connected to the second spring 25. The end of the second spring 25 away from the inner wall of the sliding groove 24 is fixedly connected to the first limiting post 26. The first limiting post 26 is slidably connected inside the sliding groove 24.

[0036] The first limiting post 26 has a first cavity 27 on its side wall. A tension spring 28 is fixedly connected to the inner wall of the first cavity 27. A T-shaped block 29 is fixedly connected to the other end of the tension spring 28. The T-shaped block 29 is slidably connected inside the first cavity 27 and is slidably connected through the side wall of the first cavity 27. The vertical plate 20 has a second cavity 33 on its inner wall. A limiting wedge block 34 is slidably connected through the inner wall of the second cavity 33. The first cavity 27 is fixedly connected to the adjacent second cavity 33 through a connecting pipe 36. The slide 23 has a slot 35 on its side wall. The limiting wedge block 34 is locked inside the slot 35. The first cavity 27, the second cavity 33 and the connecting pipe 36 are filled with hydraulic oil. The slide 23 has a wedge-shaped structure.

[0037] The scraper 13 has a semi-circular structure. The scraper 13 slides against the storage groove 39. Two temperature sensors 38 are fixedly connected to the inner wall of the round box 8. Each temperature sensor 38 is electrically connected to the adjacent motor 11.

[0038] In this invention, the ends of multiple mounting columns 3 away from the track frame 1 are fixedly connected to the side wall of the chimney, thereby installing the track frame 1 on the side wall of the chimney. Multiple footboards 2 are sequentially fixedly connected to the inner wall of the track frame 1. On the one hand, the track frame 1 can be fixedly supported, and on the other hand, users can climb up and down on the multiple footboards 2. The hoist 5 is existing technology, which mainly uses the cable 6 to drive the elevator car 37 to move vertically along the side wall of the track frame 1, thereby achieving the purpose of elevator transportation.

[0039] During the winter snow season, ice and snow often adhere to the cable 6 and freeze. This freezing can affect the normal operation of the cable 6 during the winding process, thus posing a certain safety hazard to the elevator. In this invention, since a temperature sensor 38 is installed on the inner wall of the circular box 8, when the ambient temperature reaches a freezing point, the temperature sensor 38 sends a signal to the motor 11, which is electrically connected to it. The motor 11 starts, and the output end of the motor 11 drives the rotating rod 14 to rotate. The rotating rod 14 drives the circular plate 15 to rotate, and the circular plate 15 drives the eccentrically set eccentric shaft 16 to move. Then, the eccentric shaft 16 drives the slider 19 to reciprocate vertically on the side wall of the slide block 23 through the connecting shaft 18.

[0040] When the slider 19 moves downward on the side wall of the slide block 23, the slider 19 will come into contact with the second limiting post 40, and then the second limiting post 40 will drive the slide block 23 to move downward a certain distance. The slide block 23 has a wedge-shaped structure, so the bottom end of the slide block 23 will enter the L-shaped hole 10 and slide against the first wedge block 12, thereby pushing the first wedge block 12 to slide a certain distance. At this time, the limiting wedge block 34 will be inserted into the slot 35 to limit the slide block 23. The first wedge block 12 will drive the scraper 13 fixedly connected to it to move a certain distance until it just comes into contact with the side wall of the cable 6. Then, during the winding or unwinding process, the cable 6 will continuously come into contact with the two scrapers 13 and scrape them. The two scrapers 13 will scrape off the ice and snow that are attached to the side wall of the cable 6.

[0041] The scraped ice and snow will adhere to the scraper 13 and freeze. When the slider 19 slides vertically upwards along the side wall of the slide block 23, the slider 19 will disengage from the second limiting post 40. At this time, under the action of the limiting wedge block 34 and the slot 35, the slide block 23 is in a stable state. Subsequently, when the slider 19 contacts the T-shaped block 29 on the side wall of the first limiting post 26, on the one hand, the slider 19 will squeeze the T-shaped block 29, causing the T-shaped block 29 to slide a distance in a sealed manner inside the first cavity 27. Then, the T-shaped block 29 will draw the hydraulic oil from the second cavity 33 into the first cavity 27 through the connecting pipe 36. Then, the limiting wedge block 34 will slide a distance in the opposite direction in a sealed manner, thereby disengaging the limiting wedge block 34 from the slot 35. On the other hand, The slider 19 will also drive the first limiting post 26 to slide a distance inside the sliding groove 24 by squeezing the second spring 25 through the T-shaped block 29 and the tension spring 28. After the limiting wedge block 34 and the slot 35 are completely disengaged, the first limiting post 26 slides to the end of its stroke. Then the first limiting post 26 will drive the slide block 23 to slide upward a distance. After the slide block 23 moves upward a distance, it will disengage from the first wedge block 12. Then, under the pulling force of the first spring 31, the limiting block 32 will drive the first wedge block 12 and the scraper 13 to move quickly into the storage groove 39. Since the side wall of the scraper 13 and the storage groove 39 slide tightly against each other, the storage groove 39 will clean the ice and snow adhering to the scraper 13, thereby improving the cleaning ability of the scraper 13.

[0042] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
