Description

Technical Field

[0001] The invention relates to the technical field of vertical elevator counterweights, in particular to a side-mounted counterweight lifting elevator. Background Art

[0002] As an important vertical transportation tool in modern buildings, the design of the side-mounted counterweight elevator is to improve the utilization of the shaft space by placing the counterweight device on the side wall of the shaft. However, with the increase in building height and complexity, higher requirements are placed on the smoothness and safety of elevator operation and the emergency handling capabilities after failure.

[0003] Although the traditional single drive system has a simple structure, its reliability is limited. Once the drive device fails, the elevator will not be able to continue to operate, which directly endangers the safety of passengers and causes the equipment to shut down for a long time, affecting its efficiency. In addition, the guide system of existing elevators usually adopts a fixed roller design. During operation, due to uneven friction and eccentric load, it is easy to cause offset friction between the guide rail and the roller, which not only increases wear and noise, but also weakens the stability and operating life of the system.

[0004] In view of these problems, the present invention proposes a side-mounted counterweight elevator. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please see attached Figure 1 -Attached Figure 2 An embodiment of the present invention provides a side-mounted counterweight elevator, comprising an elevator shaft 1, wherein a group of counterweight slide rails 2 are arranged on both sides of the elevator shaft 1, each group of counterweight slide rails 2 is connected to a counterweight device body 7 through a guide component 1, a mounting member 1 8 is arranged on the top of the two counterweight device bodies 7, a top seat 10 is installed on the top of the two groups of counterweight slide rails 2, through holes 6 are penetrated on both sides of the top seat 10, a traction machine 4 is installed on both sides of the top of the top seat 10, one end of a traction rope 9 is connected to the outer walls of the two mounting members 1 8, the other end of the traction rope 9 is connected to a mounting member 2 11 through the traction machine 4, a car 12 is installed at the bottom of the mounting member 2 11 through a quick-release component, a group of car slide rails 22 is installed on the rear side of the interior of the elevator shaft 1, and the car slide rails 22 are connected to the car 12 through a guide component 2.

[0032] Specifically, the side-mounted counterweight elevator of the present invention involves a set of redundant driving devices, which drive the elevator to run normally when the elevator has problems and is temporarily stopped through two traction machines 4, thereby ensuring the safety of the people inside. In this embodiment, when a traction machine 4 is damaged and cannot drive the elevator to move when it is started during the operation of the elevator, the elevator stops in the elevator shaft 1, and the other spare traction machine 4 is running, and the motor 27 is started at the same time, and the driving shaft 28 drives the driving gear 29 to rotate synchronously, thereby driving the driven gear 30 to rotate synchronously, so that the connecting shaft 31 drives the two bottom blocks 32 to rotate in the circular groove 26-1, and when the block 32 moves to the hole position on the special-shaped groove 26-2 that is consistent with the shape of the block 32, the block 32 can be disengaged from the special-shaped groove 26-2, and the tooth tips of the synchronous driven gear 30 and the driving gear 29 are separated, and at this time, under the drive of the spare traction machine 4, its spare traction rope 9 slides on the outer wall of the spare traction wheel 5, thereby driving the car 12 and the counterweight device body 7 to run alternately again, and the elevator runs briefly at this time, ensuring the safety of the people inside.

[0033] Please see attached Figure 3 -Attached Figure 7 The guide component 1 includes two groups of mounting grooves 14, and the two groups of mounting grooves 14 are respectively opened on both sides of the counterweight device body 7. One end of a movable frame 15 is rotatably arranged on the inner wall of each mounting groove 14, and a group of limiting shafts 17 are fixed on the other end of the movable frame 15. A roller 20 is sleeved on the outside of each limiting shaft 17. One end of a damper 16 is rotatably arranged on the inner wall of the mounting groove 14, and the other end of the damper 16 is rotated on the movable frame 15. Limiting components are arranged on both sides of the movable frame 15, which are used to correct the position of the roller 20 rotating outside the limiting shaft 17.

[0034] The limiting assembly includes two groups of through grooves 18, which are respectively arranged on both sides of the movable frame 15. Push plates 25 are slidably arranged inside the two groups of through grooves 18. One end of the push plate 25 is connected to a connecting plate 21, and the other end is close to the outside of the roller 1 20. A spring 2 19 is connected between the connecting plate 21 and the outer wall of the movable frame 15, and the inside of the spring 2 19 is sleeved on the outside of the push plate 25.

[0035] Specifically, when the elevator is running, the guide components 1 on both sides of the counterweight device body 7 will slide in the grooves on each set of counterweight slide rails 2 along with the counterweight device body 7. When the roller 20 rolls, it will be offset due to friction. At this time, the push plates 25 on both sides of the roller 20 will slide in the through grooves 18, thereby driving the connecting plates 21 to deform the springs 19. When the push plates 25 move, they will correct the position of the moving roller 20, thereby reducing the friction loss of its rolling. At the same time, the roller 20 will drive the movable frame 15 to move. At this time, the damper 16 will deform, driving the movable frame 15 to drive the roller 20 to fit tightly against the inner wall of the groove on the counterweight slide rail 2.

[0036] Please see attached Figure 8 The guide assembly 2 includes two mounting seats 23, the outer walls of the two mounting seats 23 are mounted on the rear side wall of the car 12, and multiple rollers 24 are rotated in the middle of both sides of the two mounting seats 23. Each group of mounting seats 23 is respectively arranged in the grooves on both sides of the car slide rail 22.

[0037] Specifically, when the car 12 moves, its rear mounting seat 23 slides on the outer wall of the car slide rail 22 through the second roller 24, thereby ensuring that the car 12 can move up and down stably and linearly under the drive of the two redundant driving devices on the top.

[0038] Please see attached Fig. 9 -Attached Fig.11 The quick-release assembly includes a limit groove 26, which is arranged at the top of the car 12. A connecting shaft 31 is arranged in the limit groove 26. Two blocks 32 are installed at the bottom of the connecting shaft 31. The top of the connecting shaft 31 is connected to the bottom of the mounting member 11 through a driving assembly.

[0039] The driving assembly includes a motor 27, the outer wall of the motor 27 is installed on the car 12, a rotating shaft 28 is fixed to the driving end of the motor 27, a driving gear 29 is installed on the top of the rotating shaft 28, a driven gear 30 is installed at the bottom of the mounting member 11, the bottom of the driven gear 30 is installed on the top of the connecting shaft 31, and the outer tooth tip of the driven gear 30 is meshed with the outer tooth tip of the driving gear 29.

[0040] Specifically, when using redundant drive devices, in order to ensure that the two drive devices do not affect each other, when replacing, the motor 27 is started, and the drive shaft 28 drives the drive gear 29 to rotate synchronously, thereby driving the driven gear 30 to rotate synchronously, so that the connecting shaft 31 drives the two bottom blocks 32 to rotate in the circular groove 26-1. When the block 32 moves to the hole position on the special-shaped groove 26-2 that is consistent with the shape of the block 32, the block 32 can be disengaged from the special-shaped groove 26-2, and the tooth tips of the synchronous driven gear 30 and the driving gear 29 that are meshed are separated.

[0041] Please see attached Fig.11 The limiting groove 26 includes a circular groove 26 - 1 and a special-shaped groove 26 - 2 . The circular groove 26 - 1 and the special-shaped groove 26 - 2 are connected. The shape of the special-shaped groove 26 - 2 is consistent with the plane shape formed by the connecting shaft 31 and the two clamping blocks 32 .

[0042] Specifically, the shape design of the limit groove 26 of the present invention is to ensure that in the engaged state, the redundant driving device can drive the car 12 to move in the elevator shaft 1 through the mounting member 11, and at the same time, when the device is alternately driven, the mounting member 11 is separated from the top of the car 12 by separating the block 32 and the limit groove 26.

[0043] Crossbeams 3 are installed on both upper and lower sides of the two sets of counterweight slide rails 2.

[0044] The outer sleeve of the traction rope 9 is provided with a spring 13.

[0045] Working principle: When the elevator of the present invention is in use, one of the traction machines 4 is started to drive the traction rope 9 to move along the outer wall of the traction wheel 5, so that the car 12 and the counterweight device body 7 move up and down alternately. When the car 12 moves, its rear mounting seat 23 slides on the outer wall of the car slide rail 22 through the roller 2 24. At the same time, the rollers 20 on both sides of the counterweight device body 7 roll in the counterweight slide rail 2. When the roller 20 rolls, it will be offset due to friction. At this time, the push plates 25 on both sides of the roller 20 will slide in the through groove 18, thereby driving the connecting plate 21 to cause the spring 2 19 to deform. When the push plate 25 moves, it will correct the position of the moving roller 20, thereby reducing its rolling friction loss. When one traction machine 4 is damaged and cannot drive the elevator to move during operation, the elevator stops in the elevator shaft 1. To ensure the installation of people in the elevator, another spare traction machine 4 is running and the motor 27 is started. The driving shaft 28 drives the driving gear 29 to rotate synchronously, thereby driving the driven gear 30 to rotate synchronously, so that the connecting shaft 31 drives the two bottom blocks 32 to rotate in the circular groove 26-1. When the block 32 moves to the hole position on the special-shaped groove 26-2 that is consistent with the shape of the block 32, the block 32 can be disengaged from the special-shaped groove 26-2, and the tooth tips of the synchronous driven gear 30 and the driving gear 29 are separated. At this time, under the drive of the spare traction machine 4, its spare traction rope 9 slides on the outer wall of the spare traction wheel 5, thereby driving the car 12 and the counterweight device body 7 to run alternately again. At this time, the elevator runs briefly to ensure the safety of the people inside.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
