Description

Technical Field

[0001] This disclosure relates to the field of personnel transport devices, and more particularly to a rope end assembly and a personnel transport device including the rope end assembly. Background Technology

[0002] An elevator is a device used to provide transportation services between specific floors within a building. Modern elevators mainly consist of a traction machine, guide rails, counterweight, safety devices, signal control system, car, and landing doors. These components are installed in the building's hoistway and machine room, respectively. Modern elevators typically use rope friction drive; the rope passes around the traction sheave, with both ends connected to the car and the counterweight. The motor drives the traction sheave to raise and lower the car. Elevators are required to be safe and reliable, have high transportation efficiency, accurate leveling, and comfortable rides. The elevator rope end assembly is an indispensable component of an elevator.

[0003] The rope end assembly, also known as a "traction rope termination device," is the connecting device at the end of the elevator rope. It securely connects the rope to the elevator car and drive unit (usually the traction machine), ensuring smooth and safe elevator ascent and descent. The quality and design of the elevator rope end assembly directly affect the overall performance of the elevator, including load-bearing capacity, operational smoothness, and safety. Therefore, the elevator rope end assembly is crucial for elevator design and installation.

[0004] In existing technologies, traditional elevator rope end assemblies consist of mechanical components such as self-locking sleeves, loops, long iron rods, and springs to secure both ends of the rope. However, existing rope end assemblies are very long and need to extend into the machine room floor for rope installation, making installation inconvenient and bulky.

[0005] Therefore, a new rope end assembly is needed. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies. According to one aspect of this disclosure, a rope end assembly for securing a rope includes a rope fixing plate and a fixing subunit. The fixing subunit is mounted on the rope fixing plate and includes: a receiving clip having a through-hole in a first direction, the receiving clip also having a receiving end and a rope exit end opposite to each other in the first direction, the width of the receiving hole decreasing from the receiving end to the rope exit end along the first direction, the second direction being perpendicular to the first direction; and a rope winding block having an insertion end and a winding end opposite to each other in the first direction, the rope passing around the winding end of the rope winding block to be disposed on opposite sides of the rope winding block in the second direction, the width of the rope winding block decreasing from the winding end to the insertion end along the first direction. The insertion end of the rope winding block is configured to insert into the receiving end of the receiving clip in the first direction, and the ropes disposed on both sides of the rope winding block extend from the rope exit end. When one side of the rope extending from the rope outlet is under tension, it moves around the rope block in a first direction relative to the receiving clamp toward the rope outlet of the receiving clamp, so as to clamp and fix the rope together with the receiving clamp.

[0007] For example, according to some embodiments of this disclosure, a plurality of the fixing sub-units are fixed on the rope fixing plate.

[0008] For example, according to some embodiments of this disclosure, the rope end assembly further includes a damping system for absorbing vibrations of the rope in the first direction.

[0009] For example, according to some embodiments of this disclosure, the damping system includes a damping block disposed below the rope fixing plate.

[0010] For example, according to some embodiments of this disclosure, the damping system includes a damping portion disposed between the rope fixing plate and the fixing subunit, the damping portion being made of an elastomeric material.

[0011] For example, according to some embodiments of this disclosure, the damping system includes a damping portion disposed between the rope fixing plate and the fixing subunit, the damping portion being a helical spring structure.

[0012] For example, according to some embodiments of this disclosure, the receiving clamp has a wedge shape, the fixing subunit further includes a fixing part, the fixing part includes a fixing end and a connecting end that are both columnar in opposite directions in a second direction, the fixing part further includes a through fixing hole, the receiving clamp is inserted into the fixing hole at the fixing end, the fixing hole allows ropes provided on both sides of the rope block to extend from the connecting end.

[0013] For example, according to some embodiments of this disclosure, the fixing part is made of an elastomeric material to serve as at least part of a damping system.

[0014] For example, according to some embodiments of this disclosure, the connecting end is fixedly connected to the rope fixing plate or the damping part.

[0015] For example, according to some embodiments of this disclosure, the fixing part is integrally formed with the receiving clip.

[0016] For example, according to some embodiments of this disclosure, the rope end assembly further includes a pin, the receiving clamp has a first insertion hole, the rope winding block has a second insertion hole, and the pin extends through the first insertion hole and the second insertion hole perpendicular to a first direction and a second direction to prevent the rope winding block and the receiving clamp from disengaging in the first direction.

[0017] For example, according to some embodiments of this disclosure, the rope block is provided with a rope groove that is recessed inward from the edge of the rope block to position the rope.

[0018] According to another aspect of this disclosure, a personnel transport device is also proposed, which includes a rope and a rope end assembly according to any embodiment of this disclosure.

[0019] For example, according to some embodiments of this disclosure, the personnel transport device further includes a car, to which the rope is connected. Attached Figure Description

[0055] To make the objectives, solutions, and advantages of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0056] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0057] In this disclosure, unless otherwise specified, the direction in which the rope passes through the fixed subunit and extends is designated as the first direction D1, the direction in which the rope is arranged around the rope block forming the two rope strands is designated as the second direction D2, the first direction D1 is perpendicular to the second direction D2, and the direction perpendicular to the first direction D1 and the second direction D2 is designated as the third direction D3, for example, as... Figure 10 As shown.

[0058] According to one aspect of this disclosure, a rope end assembly 1 is provided, which can be used to connect a rope 4 (such as...) Figure 10 The rope is clamped and secured at the end (as shown). This securely connects the rope to the elevator car and drive unit (usually the traction machine), ensuring smooth and safe elevator movement.

[0059] Figure 1 A rope end assembly 1 according to an embodiment of the present disclosure is shown, which may include a rope fixing plate 11 and a fixing subunit 12 mounted on the rope fixing plate 11. The rope fixing plate 11 is provided with a through hole corresponding to the fixing subunit 12 to allow a rope extending from the fixing subunit 12 to extend downward in a first direction D1 to connect to an elevator car. The rope fixing plate 11 may be fixed, for example, to a building mounting section high up in the building where the elevator is installed, to withstand the force exerted by the rope on the rope end assembly 1.

[0060] like Figure 1 As shown, multiple fixing sub-units 12 can be provided on the rope fixing plate 11. Each fixing sub-unit 12 can be used to fix one rope 4. Thus, multiple ropes 4 can be used to apply tension to the elevator car at the same time, increasing the maximum tension value and sharing the tension, thereby increasing the service life of the ropes.

[0061] For example, Figure 2 and Figure 3 Show Figure 1 The structure of the fixing subunit 12 of the rope end assembly 1 in the illustrated embodiment. (As shown...) Figure 2 and Figure 3 As shown, the fixing subunit 12 may include a receiving clamp 2 and a rope winding block 3 to clamp the rope. The rope 4 passes around the rope winding block 3 and exits from one end of the receiving clamp 2 in a first direction. The receiving clamp 2 and the rope winding block 3 achieve a self-locking function, that is, the greater the tension on the rope 4, the tighter the receiving clamp 2 and the rope winding block 3 clamp. The specific structure of the receiving clamp 2 and the rope winding block 3 is as follows.

[0062] According to embodiments of this disclosure, the receiving clip 2 may have a receiving hole 21 extending in the first direction D1 for receiving the rope block 3. The receiving clip 2 also has a receiving end 22 and a rope exit end 23 opposite in the first direction D1, such as... Figure 3 As shown. The receiving end 22 allows the rope block 3 to be inserted, and the rope 4, which passes over the rope block 3, extends from the rope exit end 23. Further, as... Figure 2 and Figure 3 As shown, the width of the receiving hole 21 in the second direction D2 (i.e., the arrangement direction of the two ropes formed by the rope wrapping around the rope block) decreases from the receiving end 22 to the rope exit end 23 along the first direction D1.

[0063] Correspondingly, the rope-winding block 3 may have an insertion end 31 and a rope-winding end 32 opposite to each other in the first direction D1. The rope 4 may pass around the rope-winding end 32 of the rope-winding block 3 to be positioned on opposite sides of the rope-winding block 3 in the second direction D2, such as... Figure 2 As shown, the rope-winding end 32 can be arc-shaped, allowing the rope 4 to be wound around it more effectively. The width of the rope-winding block 3 in the second direction D2 decreases from the rope-winding end 32 to the insertion end 31 along the first direction D1, to conform to the shape of the receiving hole 21 of the receiving clip 2. Thus, the insertion end 31 of the rope-winding block 3 is configured to insert into the receiving end 22 of the receiving clip 2 in the first direction D1, and the outer contour of the rope-winding block 3 fits the inner contour of the receiving hole 21. After the rope is wound around the rope-winding block 3, the rope can be clamped by the outer contour of the rope-winding block 3 and the inner contour of the receiving hole 21. To ensure strength, both the receiving clip 2 and the rope-winding block 3 can be made of metal.

[0064] For example, the rope block 3 may also be provided with a rope groove that is recessed inward from the edge of the rope block 3 to position the rope 4. This ensures that the rope 4 will not easily slip off when it is wrapped around the rope block 3.

[0065] Because the width of the rope block 3 and the receiving hole 21 decreases along the first direction D1 in the second direction D2, i.e., they are wedge-shaped, when one side of the rope 4 extending from the rope outlet 23 is under tension, this shape will convert the tension along the first direction D1 into a clamping force of the rope block 3 and the receiving hole 21. That is, the rope block 3 will move along the first direction D1 relative to the receiving clamp 2 towards the rope outlet 23 of the receiving clamp 2, thereby increasing the friction between the rope block 3 and the receiving clamp 2 and the rope 4, so that the receiving clamp 2 and the rope block 3 can clamp and fix the rope 4 together.

[0066] According to the rope end assembly disclosed herein, the long iron rod structure is eliminated, the size of the rope end assembly in the first direction is greatly reduced, the structure is simple and compact, it is easy to use, and it occupies a small volume.

[0067] Furthermore, such as Figure 2 and Figure 3 As shown, the fixing subunit 12 according to this embodiment may further include a fixing part 6, which is used to fix the receiving clip 2. For example, as Figure 3 As shown, for ease of manufacturing, the receiving clip 2 can be a thin-walled component, thus giving it a wedge shape. This wedge shape is not conducive to installation and fixation, for example, it is not conducive to direct installation onto the rope fixing plate 11 or connection to the damping part 52 described later. Therefore, a fixing part 6 can be provided to fix the receiving clip 2 and to make it easier and more secure to connect to other components.

[0068] like Figure 2 and Figure 3 As shown, the fixing part 6 may include a fixing end 62 and a connecting end 63 opposite to each other in the second direction D2. Both the fixing end 62 and the connecting end 63 may be cylindrical, such as the cylinder shown in the figure, and the cross-sectional dimension of the fixing end 62 may be larger than that of the connecting end 63 to form a stepped structure. Therefore, the fixing part 6 can be more easily installed and connected to other components, such as... Figure 1 As shown, it is installed to the rope fixing plate 11, for example, as Figure 7 and Figure 9 It is installed to the damping section 52 as shown.

[0069] The fixing part 6 may also include a fixing hole 61 extending along the first direction D1, such as Figure 3 As shown, the size of the fixing hole 61 matches the outer size of the receiving clip 2, allowing the receiving clip 2 to be inserted into the fixing hole 61 from the fixing end 62, and the fixing hole 61 allows the ropes 4 located on both sides of the rope block 3 to extend from the connecting end 63, as shown. Figure 10 As shown.

[0070] like Figure 2 and Figure 3As shown, the fixing subunit 12 according to this embodiment may further include a pin 7. Correspondingly, the receiving clip 2 may have a first insertion hole 71, and the rope winding block 3 may have a second insertion hole 72. The pin 7 may pass through the first insertion hole 71 and the second insertion hole 72 in a third direction D3 to prevent the rope winding block 3 and the receiving clip 2 from disengaging in the first direction D1.

[0071] To reduce vibration, decrease the swaying sensation in the elevator car, and enhance the user experience, a damping system can be installed in the rope end assembly to absorb vibrations in the first direction D1 of the rope. According to... Figures 1-3 In the illustrated embodiment, the damping system may include a damping block 51 disposed below the rope fixing plate 11. During installation, the damping block 51 is disposed between the rope fixing plate 11 and the building mounting portion. In particular, multiple damping blocks 51 may be disposed to absorb vibrations of the rope in the first direction D1 without hindering the extension of the rope 4 along the first direction D1. The damping block 51 may be made of an elastomeric material, such as rubber, to have good vibration absorption performance.

[0072] Furthermore, Figure 2 and Figure 3 The fixing part 6 shown may also be made of an elastomeric material (e.g., rubber) to serve as at least part of the damping system, thereby further increasing the vibration reduction performance of the rope end assembly 1.

[0073] Figure 4 and Figure 5 A fixing subunit 12 according to another embodiment of the present disclosure is shown. The fixing subunit 12 of this embodiment and... Figures 2 to 3 The difference in the illustrated embodiments is that, as Figure 4 and Figure 5 As shown, the receiving clip 2 and the fixing part 6 can be integrally manufactured. For example, both the receiving clip 2 and the fixing part 6 are made of metal, and the receiving clip 2 and the fixing part 6 are welded together. Alternatively, the receiving clip 2 and the fixing part 6 can be integrally formed by casting. This further increases the connection strength between the receiving clip 2 and the fixing part 6.

[0074] Figure 6 and Figure 7 This illustration shows a rope end assembly 1 according to another embodiment of the present disclosure, which is similar to... Figures 1 to 3 The main difference in the illustrated embodiment lies in the damping system. For example... Figure 6 and Figure 7 As shown, the damping system of the rope end assembly 1 in this embodiment may include a damping part 52, which is a cylindrical structure and may be made of an elastomeric material such as rubber. The damping part 52 may be disposed between the mounting part 6 and the rope fixing plate 11, such as... Figure 6 As shown. Figure 7As shown, a stepped portion may be provided in the internal through hole of the damping part 52 to abut against the connecting end 63 of the fixing part 6, and the end of the damping part 52 near the fixing part 6 abuts against the fixing end 62 of the fixing part 6. The damping part 52 has a simple structure, low cost, and is easy to install.

[0075] Furthermore, Figures 8-10 Another embodiment of this disclosure is shown, which is similar to... Figures 6-7 The difference in the illustrated embodiment lies in the structure of the damping section 52. For example... Figures 8-10 As shown, the damping part 52 is a helical spring structure, and can be made of metal, for example. The damping part 52 can be disposed between the mounting part 6 and the rope fixing plate 11, such as... Figure 8 and Figure 9 As shown, one end of the damping part 52 can be fixed to the fixing part 6, and the other end can be (e.g., via another fixing part 6) installed to the rope fixing plate 11. The damping part 52 has better strength and service life, and can withstand a larger vibration amplitude.

[0076] According to another aspect of this disclosure, a personnel transport device is also proposed, comprising an elevator car (not shown), ropes 4, and a rope end assembly 1 according to another aspect of this disclosure. The rope fixing plate 11 of the rope end assembly 1 can be fixedly mounted to a building (e.g., the aforementioned building installation section) on which the personnel transport device is installed. The ends of a plurality of ropes 4 can be respectively fixed to a plurality of fixing sub-assemblies 12 of the rope end assembly 1 and extend from the rope end assembly 1 to further extend downward along a first direction D1 and can be connected to the elevator car.
