Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically relating to a compensating rope tensioning device for an inclined elevator. Background Technology

[0002] As is known in the industry, traction ropes are used as the main load-bearing components in inclined elevator systems. The traction ropes bear the weight of the car and the driving force required for its operation.

[0003] The compensating rope tensioning device has at least the following positive advantages: First, it maintains stable compensating rope tension by automatically adjusting the tension to ensure it is always in an appropriate state—neither too slack nor too taut. Second, it adapts to changes in the compensating rope's tension. During elevator operation, the length and tension of the compensating rope inevitably change due to factors such as temperature and load variations; the tensioning device can adjust these changes promptly to ensure stable tension. Third, it improves operational safety by preventing the compensating rope from derailing, becoming entangled, or even causing potential safety accidents due to slackness. For example, an overly tight compensating rope increases system stress and may even lead to breakage or equipment damage. Fourth, it extends the service life of the compensating rope because appropriate tension reduces wear and fatigue, thus extending its lifespan. Furthermore, the compensating rope tensioning mechanism ensures uniform force distribution along the entire length of the compensating rope, preventing excessive wear in certain areas; fifth, it improves the smoothness of the inclined elevator car's operation, reduces vibration and noise, and enhances passenger comfort; sixth, it simplifies maintenance, as the automatic adjustment of the tensioning mechanism significantly reduces maintenance workload by minimizing manual intervention; seventh, it has good adaptability to operating conditions, as the tensioning device has excellent self-regulating adaptability to temperature and load changes; and eighth, it reduces energy loss and saves energy consumption.

[0004] Technical information on compensating rope tensioning devices for inclined elevators can be found in publicly available Chinese and foreign patent documents. For example, some patents teach the use of a spring-pulley composite structure, which automatically adjusts the tension of the compensating rope through the elastic force of the spring; others use hydraulic or pneumatic cylinders to drive tensioning wheels, compensating for sag in real time and solving the problem of slack caused by temperature changes or load fluctuations; still others use a counterweight-type tensioning system, using gravity to balance the tension of the compensating rope, and so on. However, because existing compensating rope tensioning devices lack intelligent functions, the electrical control mechanism cannot obtain timely and accurate signals of excessive slack or excessive tension in the compensating rope, thus hindering timely intervention and failing to adequately ensure that the elevator car is always in the desired ideal operating condition. Utility Model Content

[0005] The purpose of this invention is to provide a compensating rope tensioning device for inclined elevators that helps to provide dynamic information on whether the compensating rope is too slack or too taut to the electrical control mechanism at any time, thereby demonstrating good intelligent effect and providing timely handling signals to maintenance personnel, thus ensuring that the elevator car is always in an ideal safe operating condition.

[0010] In another specific embodiment of the present invention, the swing arm is configured with a swing arm cavity, the two sides and two ends of the swing arm cavity in the length direction are closed, and the upper and lower parts of the swing arm cavity in the length direction are each configured as open. The compensating rope return pulley is rotatably mounted on the free end of the swing arm in the corresponding swing arm cavity through the compensating rope return pulley pin.

[0011] In another specific embodiment of this utility model, the tensioning mechanism further includes a swing arm free end anti-sway device.

[0017] Figure 1 This is a schematic diagram of an embodiment of the present utility model;

[0018] Figure 2 for Figure 1 The diagram shows a detailed structural diagram of the tensioning mechanism. Detailed Implementation

[0019] In order to better understand the technical essence and beneficial effects of this utility model, the applicant provides a detailed description below by way of embodiments. However, the description of the embodiments is not intended to limit the solution of this utility model. Any formal but not substantive equivalent transformations made based on the concept of this utility model should be considered within the scope of the technical solution of this utility model.

[0020] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the position of the figure being described and should not be construed as a special limitation on the technical solution provided by this utility model.

[0021] Please see Figure 1The diagram illustrates the structural system of an inclined elevator, comprising a pair of car guide rails 1, which are laid parallel to each other at an incline on a foundation slope 2 serving as the guide rail carrier during use; an elevator car 3, which is mounted on a car support 31, with each side of the bottom of the car support 31 forming a sliding or rolling pair with the pair of car guide rails 1 via guide components 311 that cooperate with the pair of car guide rails 1; a drive device 4, which is located on a platform 21 at the top of the slope 2 corresponding to the pair of car guide rails 1; a compensating rope 5, a pair of counterweights 6, and a compensating rope return pulley 7. One end of the compensating rope 5 is connected to the side of the car support 31 facing the drive device 4, while the other end of the compensating rope 5 is connected to the side of the car support 31 facing away from the drive device 4 after passing through the drive device 4 and the compensating rope return pulley 7 in sequence. The counterweights 6 are connected in series to the compensating rope 5.

[0022] In this embodiment, the guide component 311 mentioned above can be either a guide shoe or a roller; the cross-sectional shape of the aforementioned pair of car guide rails 1 can be any one of the following: I-shaped, T-shaped, L-shaped, U-shaped, rectangular, circular, and other similar shapes, as long as it can meet the requirement of forming a sliding pair or rolling pair with the aforementioned guide shoe or roller.

[0023] See you later Figure 1 The key technical points of the technical solution provided by this utility model are as follows: a tensioning mechanism 8 and a signal acquisition mechanism 9 for excessive slack and excessive tension of the compensating rope tensioning device are shown. The tensioning mechanism 8 is set on the wall 10 at the bottom platform 22 of the aforementioned foundation slope 2. The signal acquisition mechanism 9 for excessive slack and excessive tension of the compensating rope is set on the tensioning mechanism 8 in a state of being distributed above and below the tensioning mechanism 8 respectively, and is electrically connected to the electrical control mechanism in the use state. The aforementioned compensating rope return wheel 7 is rotatably set on the tensioning mechanism 8.

[0024] Depend on Figure 1 As shown, a machine room 30 is provided at the position of the platform 21 at the top of the slope corresponding to the aforementioned basic slope 2, and the aforementioned drive device 4 is located in the aforementioned machine room 30. The aforementioned drive device 4 is a traction machine, and the aforementioned compensating rope 5 passes through the traction sheave 41 of the traction machine.

[0025] Please pay attention. Figure 2 And combined Figure 1The aforementioned tensioning mechanism 8 includes a wall plate fixing plate 81, a swing arm 82, a pair of tensioning arms 83, and a pair of tensioning weights 84. The wall plate fixing plate 81 is fixed to the side of the aforementioned wall 10 facing the aforementioned compensating rope return pulley 7 (i.e., the right side in the figure) through wall fixing holes 812. Preferably, a U-shaped swing arm pivot connecting seat 811 is fixed to the side of the wall plate fixing plate 81 facing the compensating rope return pulley 7 (i.e., the right side) by welding. The end of the swing arm 82 facing the wall plate fixing plate 81 (the left end in the figure) is connected by a swing arm pin. 821 is pivotally mounted on the aforementioned swing arm pivot connecting seat 811, and the end of the swing arm 82 away from the wall fixing plate 81 (i.e., the right end in the illustrated state) is configured as a swing arm free end 822 that can swing up and down. The lower ends of a pair of tensioning weights 83 are preferably welded and fixed to the two sides (front and rear sides in the illustrated state) of the swing arm free end 822 respectively, while the upper ends of the pair of tensioning weights 83 extend upward in an inverted V-shape. A pair of tensioning weights 84 are welded and fixed to the upper ends of the pair of tensioning weights 83 respectively in a corresponding state. If the pair of tensioning weights 84 and the pair of tensioning weights 83 are integrated into one structure, then they should be considered equivalent; the aforementioned compensation rope overslack and over-tension signal acquisition mechanism 9 is set on the wall fixing plate 81 in a state that is distributed above and below the end of the aforementioned swing arm 82 facing the aforementioned wall fixing plate 81 (see Figure 1 The aforementioned compensating rope return pulley 7 is rotatably mounted on the free end 822 of the aforementioned swing arm via the compensating rope return pulley pin 71.

[0026] Depend on Figure 2 As shown, the aforementioned swing arm 82 is configured with a swing arm cavity 823. The two sides and two ends of the swing arm cavity 823 are closed in the length direction, and the upper and lower parts of the swing arm cavity 823 are each configured as open. The aforementioned compensating rope return pulley 7 is rotatably mounted on the aforementioned swing arm free end 822 in the swing arm cavity 823 via the compensating rope return pulley pin 71, that is, mounted at the swing arm free end 822, that is, mounted at the right end of the swing arm 82.

[0027] The aforementioned tensioning mechanism 8 also includes a swing arm free end anti-sway device 85. The swing arm free end anti-sway device 85 includes a stop post fixing seat 851 and a pair of stop posts 852. The stop post fixing seat 851 is fixed to the aforementioned bottom platform 22 at a position corresponding to the lower part of the aforementioned swing arm free end 822. The pair of stop posts 852 are located in a longitudinal parallel state on both sides of the aforementioned swing arm free end 822, with their lower ends fixed to the stop post fixing seat 851 and their upper ends extending upward to above the aforementioned swing arm 82 when it is in a horizontal state.

[0028] Since the aforementioned anti-sway device 85 for the free end of the swing arm is composed of the aforementioned stop post fixing seat 851 and a pair of stop posts 852 forming an inverted П-shape, it can prevent the aforementioned excessive swaying of the free end 822 of the swing arm 82, which is like a fish tail effect.

[0029] Because there is a gap between the aforementioned stop post 852 and the opposite side of the aforementioned free end 822 of the swing arm, there will be no friction with the free end 822 of the swing arm. However, when the free end 822 of the swing arm wobbles forward or backward, it is blocked by a pair of stop posts 852 so that the swing arm 82 is always within the swing arm cavity 823.

[0030] Please pay close attention. Figure 1 The aforementioned compensation rope over-slack and over-tension signal acquisition mechanism 9 includes a compensation rope over-slack signal acquisition device 91 and a compensation rope over-tension signal acquisition device 92. The compensation rope over-slack signal acquisition device 91 and the compensation rope over-tension signal acquisition device 92 are fixed on the aforementioned wall fixing plate 81, that is, each is fixed to the right side of the wall fixing plate 81 through a transition piece. The compensation rope over-slack signal acquisition device 91 corresponds to the lower end of the aforementioned swing arm 7 facing the wall fixing plate 81, while the compensation rope over-tension signal acquisition device 92 corresponds to the upper end of the swing arm 7 facing the wall fixing plate 81. In the use state, the compensation rope over-slack signal acquisition device 91 and the compensation rope over-tension signal acquisition device 92 are electrically connected to the electrical control mechanism.

[0031] In this embodiment, the aforementioned compensating rope over-slack signal collector 91 and compensating rope over-tension signal collector 92 are limit switches, but they can also be micro switches, position proximity switches, reed switches, Hall effect sensors or other equivalent devices.

[0032] Driven by the drive unit 4, the drive unit 4 drives the traction sheave 41, which in turn drives the compensating rope 5, which in turn drives the elevator car 3. After the elevator car 3 of the inclined elevator has been running for a period of time, the compensating rope 5 may become too slack or too taut. This is because the travel of the inclined elevator is usually long, and the compensating rope 5 may become uneven in length due to changes in the track inclination angle (such as bends) as the elevator car 3 moves, causing abnormal tension. Temperature and material expansion and contraction, wear or displacement of mechanical parts, dynamic loads and vibrations, etc., can also cause changes in tension. Therefore, when the compensating rope 5 is excessively slack, the force exerted by the compensating rope 5 on the compensating rope return pulley 7 decreases significantly, even to the point of being negligible. Consequently, the swing arm 82 deflects downwards (i.e., rotates clockwise) around the aforementioned swing arm pin 821. As the swing arm 82 swings downwards, it touches the aforementioned excessive slack compensating rope signal collector 91 located below its left end. This excessive slack compensating rope signal collector 91 then sends a signal to the electrical control mechanism, causing the elevator to stop operation as a warning. Operation resumes only after the compensating rope 5 is replaced. Conversely, when the compensating rope 5 is too taut, the right end of the swing arm 82 moves upwards (rotates) via the compensating rope return pulley 7 until the upper surface of the left end of the swing arm 82 touches the excessive tension compensating rope signal collector 92. This excessive tension compensating rope signal collector 92 then sends a signal to the electrical control mechanism, causing the elevator to stop operation. Operation resumes only after the compensating pulley 5 is replaced.

[0033] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
