Escalator guide rail structure with shock absorption and noise reduction function

Abstract

This utility model discloses an escalator guide rail structure with shock absorption and noise reduction functions, including a track assembly pre-installed on both sides of the steps. The track assembly includes a main rail and a secondary rail, and the pulleys of the steps roll and slide on the main rail and the secondary rail respectively. Both the main rail and the secondary rail have recessed bending grooves at their tops, and shock absorption and noise reduction pads are embedded within the bending grooves. Several positioning holes are evenly distributed at the bottom of the bending grooves; several positioning protrusions are evenly distributed at the bottom of the shock absorption and noise reduction pads, and the positioning protrusions on the shock absorption and noise reduction pads correspond to the positioning holes in the bending grooves. In this escalator guide rail structure, the shock absorption and noise reduction pads are embedded in the bending grooves of the main rail and the secondary rail, transforming the original rigid contact between the step pulleys and the track assembly into a soft rolling contact between the step pulleys and the shock absorption and noise reduction pads. This effectively absorbs and attenuates the impact and vibration energy generated during pulley operation, significantly reducing operating noise, improving operational stability, and simultaneously reducing component wear and extending service life, thus achieving the function of shock absorption and noise reduction.

Description

Technical Field

[0001] This utility model relates to the field of escalator manufacturing technology, and in particular to an escalator guide rail structure with shock absorption and noise reduction functions. Background Technology

[0002] Traditional escalator guide rails, including main and auxiliary rails, are typically machined directly from metal profiles such as steel or aluminum alloy and fixed to a truss structure via brackets. The pulleys of the escalators run directly on these guide rails. Traditional escalator guide rails present the following main problems in actual operation:

[0003] 1. Vibration Transmission: During operation, steps / pedals generate impacts and vibrations, especially at bends or joints in the guide rails. Traditional rigid guide rails directly transmit these vibrations to the supporting structure and building, generating structural noise and solid-borne sound, which affects passenger comfort and the building environment.

[0004] 2. Operating noise: The direct contact and friction between the escalator pulleys and the working surfaces of the guide rails, as well as the impact when the pulleys pass through the guide rail joints, will generate significant air noise, rolling noise, and impact noise.

[0005] 3. Increased wear: Continuous impact and vibration will accelerate the wear of the guide rail working surface, the step pulley and the guide rail joint, shorten the service life of the components and increase maintenance costs. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an escalator guide rail structure with shock absorption and noise reduction functions to overcome the deficiencies of the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An escalator guide rail structure with shock absorption and noise reduction function includes a rail group symmetrically preset on both sides of the step. The rail group includes a main rail located on the outer side of the step and a secondary rail located on the inner side of the step. Pulleys symmetrically arranged on both sides of the step roll and slide on the preset main rail and secondary rail respectively.

[0009] The top of both the main rail and the auxiliary rail is recessed with bending grooves, and shock-absorbing and noise-reducing pads are embedded in the bending grooves.

[0010] Furthermore, the bottom of the bending groove is uniformly provided with a number of positioning holes along the length of the track; the bottom of the shock-absorbing and noise-reducing pad is uniformly provided with a number of positioning protrusions along the length of the track, and the positioning protrusions on the shock-absorbing and noise-reducing pad correspond one-to-one with the positioning holes in the bending groove.

[0011] Preferably, the shock-absorbing and noise-reducing pad is T-shaped, comprising an integrally connected horizontal portion and a vertical portion.

[0012] Furthermore, the lateral thickness of the shock-absorbing and noise-reducing pad is 4mm to 8mm.

[0013] Preferably, the shock-absorbing and noise-reducing pad is made entirely of ultra-high molecular weight polyethylene (UHMWPE) composite material.

[0014] Preferably, the outer edge of the main rail is further provided with a limit stop.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this case, the escalator guide rail structure has shock-absorbing and noise-reducing pads embedded in the bending grooves of the main rail and the auxiliary rail. This transforms the rigid contact between the pulleys of the escalator steps and the rail assembly into a soft rolling contact between the pulleys of the steps and the shock-absorbing and noise-reducing pads. This effectively absorbs and attenuates the impact and vibration energy generated during the operation of the pulleys, significantly reduces operating noise, including structural noise and air noise, improves the smoothness of operation and riding comfort, while also reducing component wear, extending service life, and achieving the function of shock absorption and noise reduction.

[0017] 2. The escalator guide rail structure in this case is easy to install and has low maintenance costs.

[0018] To provide a clearer understanding of this invention, the preferred embodiments of this invention will be described below in conjunction with the accompanying drawings. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] Furthermore, if terms such as "first" or "second" are used for descriptive purposes only, they are mainly used to distinguish different devices, components, or parts whose specific types and structures may be the same or different, and are not used to indicate or imply the relative importance or quantity of the indicated devices, components, or parts, and should not be construed as indicating or implying relative importance.

[0027] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] Please also refer to Figure 1-4 This utility model provides an escalator guide rail structure with shock absorption and noise reduction function, including a rail group symmetrically preset on both sides of the step 1. The rail group includes a main rail 2 located on the outside of the step 1 and a secondary rail 3 located on the inside of the step 1. Pulleys 11 symmetrically arranged on both sides of the step 1 roll and slide on the preset main rail 2 and secondary rail 3 respectively, thereby enabling the normal operation of the escalator.

[0029] Furthermore, both the top of the main rail 2 and the secondary rail 3 are recessed with bending grooves 4, and shock-absorbing and noise-reducing pads 5 are embedded in the bending grooves 4. The pulleys 11 of the step 1 roll and slide on the shock-absorbing and noise-reducing pads 5 on the main rail 2 and the secondary rail 3 respectively, thereby avoiding rigid contact between the pulleys 11 and the rails and achieving the effect of the shock-absorbing and noise-reducing pads 5.

[0030] Furthermore, the bottom of the bending groove 4 is evenly provided with a number of positioning holes 41 along the length of the track; the bottom of the shock-absorbing and noise-reducing pad 5 is evenly provided with a number of positioning protrusions 51 along the length of the track. The positioning protrusions 51 on the shock-absorbing and noise-reducing pad 5 correspond one-to-one with the positioning holes 41 in the bending groove 4, so that the shock-absorbing and noise-reducing pad 5 can be stably fixed in the bending groove 4 and is not easy to shift. At the same time, it is also easy to remove and replace the shock-absorbing and noise-reducing pad 5 from the bending groove 4 during later maintenance.

[0031] Preferably, in this embodiment, the shock-absorbing and noise-reducing pad 5 is T-shaped, which includes an integrally connected horizontal part and a vertical part. The T-shaped design can be stably embedded in the bending groove 4.

[0032] Preferably, in this embodiment, the thickness of the transverse portion of the shock-absorbing and noise-reducing pad 5 is 4mm to 8mm; the entire shock-absorbing and noise-reducing pad 5 is made of ultra-high molecular weight polyethylene (UHMWPE) composite material.

[0033] Furthermore, a limit stop 21 is also provided on the outer edge of the main rail 2. The limit stop 21 limits the pulley 11 of the step 1 on the main rail 2, further ensuring the stability of the step 1 operation.

[0034] Compared to existing technologies, the escalator guide rail structure with shock absorption and noise reduction function in this case has a shock absorption and noise reduction pad 5 embedded in the bending groove 4 of the main rail 2 and the auxiliary rail 3. This changes the rigid contact between the pulley 11 of the escalator step 1 and the track assembly to a soft rolling contact between the pulley 11 of the step 1 and the shock absorption and noise reduction pad 5. The track assembly can effectively absorb and attenuate the impact and vibration energy generated by the pulley 11 during operation, significantly reduce operating noise, including structural noise and air noise, improve the smoothness of operation and riding comfort, and at the same time reduce component wear, extend service life, and play a role in shock absorption and noise reduction.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
