Abstract
Description
Technical Field
[0001] This utility model relates to the field of escalator floor slabs, and more particularly to an adjustable structure for a reinforcing support of the middle and rear escalator floor slab. Background Technology
[0002] In modern society, escalators and moving walkways serve as crucial vertical and horizontal transportation tools in public transportation and commercial spaces, widely used in densely populated areas such as shopping malls, subway stations, airports, and train stations. The safe and stable operation of these devices is essential for ensuring smooth passenger flow and personal safety. The middle and rear panels of escalators and moving walkways are key components, typically located in the middle and rear sections, playing a vital role in supporting the steps, transmitting loads, and connecting other escalator parts. The structural design and performance of the middle and rear panels directly affect the overall strength, rigidity, and stability of the escalator.
[0003] In early escalator designs, the structure of the middle and rear slabs was relatively simple, usually using a single flat plate structure and ordinary steel. Currently, escalator floor slabs are all spliced with straight seams, with support plates between the middle and rear slabs, but no fixing or adjustment structure.
[0004] However, in actual use, straight seam splicing, which relies solely on simple straight welds or bolts, is prone to stress concentration under long-term high-frequency loads. For example, when passengers step on the splice, the weld develops micro-cracks due to repeated impacts, eventually leading to fracture. Therefore, based on the aforementioned issues, a reinforced support adjustment structure for the rear panel of the escalator was developed. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an adjustable support structure for the middle and rear plates of escalators, which aims to solve the problem in the prior art that "straight seam splicing is only connected by simple straight welds or bolts, which is prone to stress concentration under long-term high-frequency loads, eventually leading to fracture".
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an escalator rear plate reinforcement support adjustment structure, including a base frame, a Z-shaped support at the top of the base frame, and an adjustment mechanism inside the Z-shaped support;
[0007] The adjustment mechanism includes a connecting block, the interior of which is located inside the Z-shaped bracket, and a bolt B is threadedly connected to the interior of the connecting block.
[0008] As a further description of the above technical solution: the inner wall of the Z-shaped bracket is threaded with bolt A, and the bottom of the outer wall of bolt A is threaded to the top of the base frame.
[0009] As a further description of the above technical solution: the inner wall of the Z-shaped bracket is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a slider, and the outer wall of the slider is fixedly connected to the outer wall of the connecting block.
[0010] As a further description of the above technical solution: the upper extension end of the bolt B is threadedly connected to a middle and rear plate.
[0011] As a further description of the above technical solution: the number of adjustment mechanisms is four sets, and the four sets of adjustment mechanisms are symmetrically connected to the inner wall of the Z-shaped bracket.
[0012] As a further description of the above technical solution: the number of bolts A is four sets, and the four sets of bolts A are symmetrically connected at equal intervals on the top of the Z-shaped bracket.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, a stable connection and precise adjustment are achieved through the cooperation of key components such as the base frame, Z-shaped bracket, adjustment mechanism, bolt A, and bolt B. The base frame provides a stable foundation for the entire structure, and the Z-shaped bracket, with its unique "Z"-shaped bending design, possesses excellent torsional and bending resistance, ensuring the relative position stability of the middle plate and the rear plate. Bolt A detachably fixes the Z-shaped bracket to the base frame, ensuring a stable connection and facilitating installation and disassembly.
[0015] 2. In this utility model, the connecting block, slide groove and slider in the adjustment mechanism cooperate with each other to flexibly adjust the position according to the different thread hole spacing of the middle and rear plates; bolt B can finely adjust the position of the rear plate so that the middle plate and the rear plate panel are on the same horizontal plane, eliminating the height difference of the splicing seam and ensuring the accuracy and stability of the installation of the middle and rear plates of the escalator.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of an escalator rear panel reinforcement support adjustment structure, including a base frame 1. The base frame 1 serves as the basic load-bearing component of the entire structure, providing a stable mounting plane for the Z-shaped support 2. The Z-shaped support 2 is an integrally bent component comprising an upper horizontal plate, a lower horizontal plate, and a vertical plate, forming two supporting planes. The lower horizontal plate abuts against the rear panel, and the upper horizontal plate supports the middle panel. Its "Z"-shaped bending design is similar to a bridge truss structure, naturally possessing anti-torsion and anti-bending capabilities. Even under long-term dynamic loads, it can maintain the relative position stability of the middle and rear panels, avoiding panel misalignment and overlap due to support deformation. An adjustment mechanism 5 is provided inside the Z-shaped support 2. The adjustment mechanism 5 allows for flexible adjustment of the position of the middle and rear panels 4, ensuring that the middle and rear panels are on the same horizontal plane. The adjustment mechanism 5 includes a connecting block 511, which can slide inside the Z-shaped support 2. By adjusting its position, it can adapt to different thread hole spacings of the middle and rear panels 4. The connecting block 511 has internal... Inside the Z-shaped bracket 2, the connecting block 511 has an internal threaded connection to bolt B513. Bolt B513 is used to connect the middle and rear plates 4. By rotating it, the position of the rear plate can be finely adjusted. If the rear plate is slightly lower at a certain point, tightening the corresponding bolt B513 can raise the rear plate to be flush with the middle plate, eliminating the height difference at the splicing seam. The inner wall of the Z-shaped bracket 2 has a threaded connection to bolt A3. Bolt A3 is used to detachably fix the Z-shaped bracket 2 to the base frame 1 for easy installation and disassembly. The bottom of the outer wall of bolt A3 is threaded... The Z-shaped bracket 2 is attached to the top of the base frame 1. The inner wall of the Z-shaped bracket 2 is provided with a sliding groove 514. The sliding groove 514 provides a guide track for the sliding of the connecting block 511, ensuring its sliding stability and accuracy. The inner wall of the sliding groove 514 is slidably connected to a slider 512. The slider 512 cooperates with the sliding groove 514 to reduce the friction when the connecting block 511 slides, making the adjustment process smoother. The outer wall of the slider 512 is fixedly connected to the outer wall of the connecting block 511. The upper extension end of the bolt B513 is threadedly connected to the middle and rear plate 4.
[0024] Reference Figures 2-4 There are four sets of adjustment mechanisms 5, which are symmetrically connected to the inner wall of the Z-shaped bracket 2. Through the symmetrical distribution of multiple sets of adjustment mechanisms 5, the middle and rear plates 4 can be adjusted evenly, ensuring the consistency and stability of the adjustment effect. There are four sets of bolts A3, which are symmetrically connected to the top of the Z-shaped bracket 2 at equal intervals. The symmetrical fixing with multiple sets of bolts A3 can enhance the stability of the connection between the Z-shaped bracket 2 and the base frame 1 and improve the reliability of the overall structure.
[0025] Working principle: The Z-shaped bracket 2 (which is an integral bent piece consisting of an upper horizontal plate, a lower horizontal plate, and a vertical plate, forming two supporting planes (the upper horizontal plate supports the middle plate, and the lower horizontal plate abuts against the rear plate)) is detachably connected to the lower horizontal plate of the base frame 1 via bolt A3. The middle and rear plates 4 are detachably connected to the top of the upper horizontal plate of the Z-shaped bracket 2 via bolt B513 in the adjustment mechanism 5. The "Z"-shaped bending design of the Z-shaped bracket 2 (similar to a bridge truss structure) naturally has anti-torsion and anti-bending capabilities. Even under long-term dynamic loads, it can maintain the relative position stability of the middle plate and the rear plate, avoiding panel misalignment and overlap caused by bracket deformation.
[0026] A groove 514 is provided on the upper horizontal plate of the Z-shaped bracket 2. A connecting block 511 is slidably connected to the inner wall of the groove 514, and a slider 512 is installed on the outer wall of the connecting block 511. By adjusting the position of the connecting block 511, it is convenient to adjust according to different thread hole spacings of the middle and rear plates 4. This prevents the upper horizontal plate of the Z-shaped bracket 2 from not being accurately connected to the middle and rear plates 4 after the lower horizontal plate of the Z-shaped bracket 2 is fixed, thus avoiding delays in the construction process. At the same time, the position of the rear plate can be finely adjusted by rotating the bolts to ensure that the middle plate and the rear plate are on the same horizontal plane. For example, if the rear plate is found to be slightly lower in a certain position, the rear plate can be raised to be flush with the middle plate by tightening the bolts at the corresponding positions, eliminating the height difference at the splicing seam.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
