Description

Technical area

[0001] The present invention relates to the field of passenger transport devices, in particular to a suspension assembly and a passenger transport device with this suspension assembly. background

[0002] The elevator trailing cable and balancing chain are necessary components of the elevator, and the reliable installation of the trailing cable and balancing chain has a direct impact on the elevator's performance and operational safety.

[0003] The elevator trailing cable is the main carrier for transmitting travel commands and exchanging information between the elevator car and the control cabinet in the machine room. One end of the trailing cable is connected and fixed to the control cabinet in the machine room, while the other end is connected to the elevator car and moves with it. It's easy to see that the elevator car must bear a certain proportion of the deadweight of the trailing cable.

[0004] As buildings grow taller and elevators become more frequently used, the length and number of elevator trailing cables increase, and with them, the weight of the cables. This additional weight compromises the static balance of the elevator car, which in turn impacts the comfort of elevator operation.

[0005] The elevator balance chain is a component that plays a balancing role in the operation of the elevator. During elevator operation, the length of the wire ropes on the car side and the counterweight side are constantly changing, causing the weight of the wire ropes on both sides of the traction sheave to change. This has little impact on the operating performance of the elevator when the lifting height of the elevator is not too large, but when the lifting height exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers. Therefore, when the lifting height of the elevator exceeds a certain height, it is necessary to establish a balancing chain for the elevator to compensate for the weight change caused by the height change.

[0006] However, installing and supporting the trailing cables and / or balancing chains is challenging, and the suspension may need to be customized for different elevator types. For example, existing trailing cable supports are typically mounted on the car with fixed suspension points based on the structural design, and the cable's deadweight is balanced by counterweights on the car floor. However, once the cable's deadweight is large or the structural size deviates, maintaining this balance becomes difficult. For example, some other existing suspension devices are attached to multiple car supports, which complicates installation, requires a lot of space, is heavy, and is expensive.

[0007] There is therefore a need for a universally applicable, adjustable, high-strength and simple design of the suspension assembly Summary of the invention

[0008] The purpose of the present invention is to provide a suspension assembly that overcomes the deficiencies of the prior art.

[0009] The suspension assembly according to the present invention can be mounted on a single beam of the elevator car, and the suspension position can be adjusted along the beam to select the most suitable suspension point for different elevator models, facilitating the adjustment of the static balance of the car and contributing to improving the comfort of elevator operation. The suspension assembly according to the present invention can include various removable hangers that can be replaced with different hangers to achieve different supporting functions, making it possible to suspend various objects with a single set of components, such as supporting different types of trailing cables and / or balancing chains.This eliminates the need to design and manufacture different components for different objects, facilitating mass production and significantly reducing costs and assembly problems.

[0010] According to a technical embodiment of the present invention, the suspension assembly further comprises, for example, one or more adjustment pads or adjustment blocks, wherein the adjustment pad(s) is / are attached to the back plate and / or the mounting part between the first counterpart and the second counterpart, wherein the adjustment pad(s) is / are arranged within the sleeve to adjust the dimensions of the interior of the sleeve at the adjustment pad pad.

[0011] According to a technical embodiment of the present invention, the first mounting portion is further away from the back plate than the second mounting portion, for example in a direction perpendicular to the back plate.

[0012] According to a technical embodiment of the present invention, the distance between the planes in which the first mounting portion and the second mounting portion are respectively arranged towards the surface of the back plate is, for example, 2 to 4 mm greater than the thickness of the first end when the mounting part is not firmly connected to the back plate and before the mounting part and the back plate are deformed.

[0013] According to a technical embodiment of the present invention, the second end is, for example, coplanar or perpendicular to the first end.

[0014] According to a technical embodiment of the present invention, the suspension assembly comprises, for example, a second hanger, wherein the second hanger is attached to the second counterpart on the side of the back plate opposite the mounting part.

[0015] The present invention also proposes a passenger transport device comprising a mounting beam extending in a second direction and a suspension assembly according to any of the preceding technical solutions, wherein the shaped sleeve surrounds the mounting beam so that the suspension assembly is fixed to the mounting beam.

[0016] According to a technical embodiment of the present invention, the mounting beam is non-uniformly dimensioned in a first direction, wherein the suspension arrangement comprises one or more adjustment pads, wherein the adjustment pad(s) is / are mounted between the first counterpart and the second counterpart on the back plate and / or the mounting part, wherein the adjustment pad(s) is / are arranged within the sleeve such that the mounting beam is clamped against the adjustment pad(s) at the adjustment pad.

[0017] According to a technical embodiment of the present invention, for example, the second end of the first hanger comprises a first tow cable carrier, wherein the passenger transport device comprises a first tow cable, wherein the first tow cable carrier carries the first tow cable.

[0018] According to a technical embodiment of the present invention, for example, the second end of the first hanger comprises a release buckle, and the passenger transport device comprises a balancing chain, wherein the release buckle carries the balancing chain.

[0019] According to a technical embodiment of the present invention, the second hanger comprises, for example, two mutually perpendicular sections, wherein one section of the second hanger is attached to the back plate and a second tow cable support is attached to the other section of the second hanger, wherein the personnel transport device comprises a second tow cable and the second tow cable support serves to support the second tow cable.

Detailed description of the embodiments

[0020] To further clarify the purpose, program, and advantages of the technical solutions of the present invention, the technical solutions of the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings of specific embodiments of the present invention. Unless otherwise indicated, the terms used herein have the meaning commonly used in the art. Identical mounting symbols in the accompanying drawings represent identical components.

[0021] When describing the present invention, it should be noted that the terms "mounted," "connected," and "attached," unless expressly stated and limited otherwise, are to be understood in the broadest sense, e.g., as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection via an intermediate medium; or as a connection within two elements. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection via an intermediate medium; and it may be a connection within the two elements. The specific meaning of the above terms in the present invention will be understood by those skilled in the art in certain cases.

[0022] For ease of illustration, in the present invention, the direction of separation between the first counterpart and the second counterpart on the back plate is referred to as the first direction D1, the direction of extension of the mounting bracket is referred to as the second direction D2, the first direction D1 is perpendicular to the second direction D2, and the back plate is parallel to the first direction D1 and the second direction D2, as shown by the black arrows in the Fig. 1 to 2 and Fig. 4 to 6 are displayed.

[0023] Fig. 1 and Fig. 2 show a three-dimensional schematic exploded view and a side view of a suspension assembly according to embodiments of the present invention. In conjunction with the Fig. 1 and Fig. 2, a suspension assembly according to the present invention may comprise a back plate 3, a mounting part 5 and a first hanger 1, wherein the first hanger 1 is mounted via the back plate 3 and the mounting part 5 on a mounting beam 6 (as shown in the Fig. 4 to 6).

[0024] In particular, the back plate 3 extends parallel to the first direction D1 and the second direction D2 and comprises a first counterpart 31 and a second counterpart 32 spaced apart from each other along the first direction D1, as shown in the Fig. 1 and Fig. 2. The first counterpart 31 and the second counterpart 32 can be arranged at both ends of the back plate 3 along the first direction D1. The first counterpart 31 and the second counterpart 32 of the back plate 3 are used to cooperate with the mounting part 5 to form an annular sleeve that can be attached to the mounting beam.

[0025] In particular, the mounting part may comprise a C-shaped curved section 53 and a first mounting section 51 and a second mounting section 52 adjacent to each end of the curved section 53. The first mounting section 51 and the second mounting section 52 are arranged parallel to each other so that they can cooperate with the first counterpart 31 and the second counterpart 32 of the back plate 3, whereby the back plate 3 and the mounting part 5 can be fastened to each other. For example, the first counterpart 31 and the second counterpart 32 can be provided with through holes, and the first mounting section 51 and the second mounting section 52 are also provided with through holes, all of which are fastened with screws. In addition, other fastening methods conceivable in the art are also possible, such as riveting, welding, gluing, and the like, but are not limited thereto.

[0026] As a result, the back plate 3 and the curved section 53 of the mounting part 5 form a sleeve that surrounds it on all sides and extends in the second direction D2, which sleeve can have an inner contour adapted to the outer contour of the mounting beam, so that the formed sleeve surrounds the mounting beam 6, whereby the suspension assembly can be fastened to the mounting beam 6. In particular, the curved section 53 can be a C-shaped structure formed from three straight plates, two of which are arranged perpendicular to the C-shaped structure of the remaining straight plate. Furthermore, the sleeve formed from the curved section 53 and the straight plate 6 has a rectangular cross-section, and the corresponding mounting beam 6 can also have a rectangular shape, so that the mutually adapted rectangular contour contributes to the stability of the fastening and prevents movement of the suspension assembly around the mounting beam 6.

[0027] Furthermore, different mounting beams 6 may have different dimensions, or the mounting beams 6 may have irregular cross-sectional shapes. In particular, in the existing, mass-produced and used beams, the dimensions along the first direction D1 are not uniform, i.e., the thicknesses of the opposite ends in the first direction D1 are different, e.g., the thicknesses near the first mounting portion 51 are smaller. To solve this problem for a more secure mounting fit, a suspension assembly according to the present invention may include one or more adjustment pads 4. As shown in the Fig. 1 and Fig. 2, an adjustment pad 4 can be provided, which can be attached to the back plate 6. In particular, the adjustment pad(s) are mounted between the first counterpart and the second counterpart and arranged in the shaped sleeve to enable adjustment of an interior space of the sleeve on the mounting beam 6, whereby the inner contour of the remaining space within the sleeve is better adapted to the outer contour of the mounting beam 6, so that the mounting beam 6 is clamped against the adjustment pad 4. In addition, the adjustment pad 4, as shown in Fig. 4, may be provided on the curved section 53 of the mounting beam 5. In particular, an adjustment pad 4 may optionally be provided on both the back plate 3 and the mounting part 5.

[0028] Furthermore, the first hanger 1 of the suspension assembly according to the present invention may have a first end 11 and a second end 12 which are opposite each other in the first direction D1, wherein the first end 11 is intended for attachment to the back plate 3 and / or the mounting part 5, in particular both to the back plate 3 and to the mounting part 5, e.g. as shown in the Fig. 1 and Fig. 2. Here, the first end 11 is provided for insertion between the first counterpart 31 and the first mounting portion 51, in particular for clamping by the first counterpart 31 and the first mounting portion 51. The first end 11 can be arranged between the first counterpart 31 and the first mounting portion 51, in particular clamped by the first counterpart 31 and the first mounting portion 51. As a result, the first mounting portion 51 and the second mounting portion 52 are arranged parallel to the back plate and in different planes. As shown in Fig. 3, the first mounting portion 51 may be further away from the back plate 3 in a direction perpendicular to the back plate 3 than the second mounting portion 52, thereby reserving a space for the thickness of the first end 11 so that the first end 11 can be fixed between the first mounting portion 51 and the back plate 6.

[0029] To ensure a stable and safe installation on this basis, a distance G of 2-4 mm, which is greater than the thickness of the first end 11, can be left between the levels (in Fig. 3 as two dashed lines), on which the mounting parts 5 are arranged towards the surface of the back plate 3 (the distance G is shown in Fig. 2 by the two opposite arrows), when the mounting part 5 is not connected to the back plate 3 and before the mounting part 5 and the back plate 3 are deformed, such as the mounting parts (e.g. screws) on the first counterpart 31 are not tightened, that is, both the back plate 3 and the mounting part 5 are not deformed due to the fastening force of the mounting parts. When tightening by means of the fasteners, the gap G disappears, resulting in the first end 11 being clamped by the first counterpart 31 and the first mounting portion 51, which means that the back plate 3 and the mounting part 5 together have a deformation of 2-4 mm in an opposite direction, thereby ensuring that the sleeve formed by the back plate 3 and the mounting part 5 is tightened with respect to the mounting beam 6 to ensure the reliability and safety of the installation.

[0030] Furthermore, the second end 12 of the first hanger 1 can be provided with a functional component, e.g. a first trailing cable carrier 13, as shown in the Fig. 1 to 2 and Fig. 4 to 5, wherein the first trailing cable support 13 can be used to support a first trailing cable (not shown), wherein the first trailing cable is in particular a high-speed trailing cable used in high-speed elevators, wherein the elevator car can move at a speed of more than 2.5 m / s relative to the shaft.

[0031] As in Fig. 4 and Fig. 6, this second end 12 may be parallel, e.g. coplanar, to the first end 11, especially if the two are one and the same integrally molded component. As shown in Fig. As shown in Figure 5, this second end 12 can be perpendicular to the first end 11, especially if the two are different components connected by additional connecting elements. Thus, depending on the various orientations of the tow cable, the first hanger 1 can be selected with a second end 12 with a corresponding orientation.

[0032] A functional component of the first hanger 1 according to the present invention may also be a release buckle 14, one or more of which may be attached to the second end 12 for carrying a compensation chain, as shown in the Fig. 6 and Fig. 7 (not shown). The suspension assembly for supporting the balance chain and the suspension assembly for supporting the tow cable can thus share the remaining components except for the first hanger to reduce the cost and difficulty of assembly.

[0033] Furthermore, the suspension assembly according to the present invention may comprise a second hanger 2 which can be attached to the second counterpart 32, in particular to a side of the back plate opposite the mounting part, as shown in the Fig. 1 and Fig. 2. The second hanger may comprise two mutually perpendicular sections, one section of the second hanger being fixed to the back plate 3 and the other section of the second hanger being connected to a second trailing cable support 21. The second trailing cable support 21 may be used to support a second trailing cable (not shown), wherein the second trailing cable is, in particular, a low-speed elevator (wherein the maximum movement speed of the car with respect to the shaft may be less than 2.5 m / s). The low-speed trailing cable is used. The suspension assembly according to the present invention is thus suitable for various types of elevators.

[0034] The present invention also proposes a passenger transport device, such as, but not limited to, an elevator, an escalator, and the like. The passenger transport device according to the present invention comprises a mounting beam 6 and a suspension assembly as described above, wherein the mounting beam 6 may have uniform or non-uniform dimensions along the first direction D1. Regardless of whether the dimensions are uniform or not, the suspension assembly according to the present invention is adapted to be mounted and secured to the mounting beam 6 by means of a fastening as described above.

[0035] For example, the passenger transport device is a high-speed elevator whose car (not shown) can move at a speed of more than 2.5 m / s relative to a shaft (not shown), and the passenger transport device comprises a first trailing cable, wherein the first trailing cable is used for transmitting operating instructions and information interaction between the car and the machine room control cabinet. One end of the first trailing cable is connected to the machine room control cabinet and is stationary, the other end is connected to the elevator car and moves together with the elevator car. The suspension assembly comprises a first hanger 1 provided with a first trailing cable support 13. The first trailing cable is supported by the first trailing cable support 13, as shown in the Fig. 4 and Fig. 5 is shown.

[0036] For example, the passenger transport device is a low-speed elevator in which the car (not shown) moves at a maximum speed of 2.5 m / s relative to the shaft (not shown). The passenger transport device includes a second trailing cable used to transmit operating commands and information interactions between the car and the machine room control cabinet. One end of the second trailing cable is connected to the machine room control cabinet and is stationary; the other end is connected to the car and moves with the car. The suspension assembly includes a second hanger 2 with a second trailing cable support 21. The second trailing cable is carried by the second trailing cable support 13, as shown in Fig. 1 and Fig. 2 is shown.

[0037] During elevator operation, the lengths of the ropes on the car side and the counterweight side constantly change, thereby changing the weight of the ropes on both sides of the traction sheave. The passenger transport device according to the present invention may also include a compensating chain or rope (not shown), wherein the compensating chain serves to act as a counterweight for the operation of the elevator to compensate for weight changes due to changes in altitude. The suspension assembly comprises, as shown in Fig. 6, a first hanger 1 provided with a release buckle 14, and the compensation chain is carried by the release buckle.

For example, the above-mentioned embodiments (and / or aspects thereof) may be used in combination with one another. Furthermore, many changes may be made to adapt particular embodiments or materials to the teachings of the present invention without departing from the scope of the present invention.
