[0002] The steps of an extra-wide moving walkway are wide moving steps designed specifically for large public places, which can accommodate more pedestrians at the same time, improving the passing efficiency and comfort. Due to its large load-bearing capacity, it is particularly important to use a specially designed support structure. These support structures can increase the overall strength and stability, ensure the smooth operation of the steps under high load, reduce wear, and extend the service life. They can also enhance safety, prevent the steps from deforming or breaking during use, ensure compliance with design and regulatory requirements, and thus guarantee the safety of pedestrians and the reliability of the facilities.

[0003] In most cases during the use of the existing support structure, a single middle support guide rail is set in the middle of the step chain for supporting the steps.

[0028] Reference Figure 1 、 Figure 2 and Figure 3 An embodiment provided by the present utility model: A support structure applicable to the steps of an extra-wide escalator, comprising:

[0029] A step board 1, one side of the outer wall of the step board 1 is fixedly connected with a fixed shaft 2, and a roller 3 is rotatably connected to the outer wall of the fixed shaft 2;

[0033] Specifically, when the step board 1 operates, the pressure borne is transmitted to the support rail 4; the support rail 4 receives the pressure and further transmits it to the fixed box 8 through the connecting frame 7; the transmission of the pressure drives the first runner 11 to run smoothly on the guide rail, and then enables the first runner 11 to achieve precise limit sliding inside the fixed box 8; at this time, the movement of the first runner 11 pushes the hinge block 12 on the sliding plate 10 to move synchronously; the movement of the hinge block 12 causes the two rotating plates 13 to start rotating, and this rotation drives the second runner 1501 to slide on the inner wall of the fixed box 8; the movement of the second runner 1501 causes the tension spring 1502 to stretch, thereby effectively reducing the pressure borne by the step board 1; through this pressure reduction mechanism, the impact force received by the roller 3 during operation is also significantly reduced; this design not only effectively disperses the pressure, but also optimizes the operation process and extends the service life of the step board 1; the entire system ensures the stability of operation and the durability of the equipment through precise mechanical cooperation, significantly improving the performance and reliability of the step board 1.

[0034] Reference Figure 2 、 Figure 4 and Figure 5, a fixed rod 16 is rotatably connected to the inner wall of the limit wheel 6, a slider 17 is slidably connected to the inside of the connecting plate 5, and the fixed rod 16 is fixedly connected to the upper surface of the slider 17; a second limiting rod 18 is fixedly connected to the inside of the connecting plate 5, and a first spring 19 is sleeved on the outer wall of the second limiting rod 18, and one end of the first spring 19 is fixedly connected to one side of the outer wall of the slider 17; a bolt 20 is fixedly connected to the outer wall of the support rail 4, and a threaded sleeve 21 is threadedly connected to the outer wall of the bolt 20; a sliding block 22 is slidably connected to one side inside the support rail 4, and a pushing block 23 is fixedly connected to one side of the outer wall of the sliding block 22, and the pushing block 23 is slidably connected to the inside of the support rail 4; an insertion block 24 is fixedly connected to one side of the outer wall of one support rail 4, a positioning rod 25 is arranged directly below the insertion block 24, and the insertion block 24 and the positioning rod 25 are slidably connected to the inside of the other support rail 4; two symmetrically arranged clamping blocks 27 are slidably connected to the inside of the insertion block 24, a second spring 26 is installed between the two clamping blocks 27, and the clamping blocks 27 are slidably connected to the inside of the other support rail 4;

[0035] Specifically, when taking out multiple support rails 4 and matching them with the step board 1 to be installed, insert the insertion block 24 and the positioning rod 25 on one side of one support rail 4 into the inside of the other support rail 4. Through this operation, the positioning rod 25 achieves accurate and rapid positioning; at this time, the expansion and contraction force of the second spring 26 pushes the clamping blocks 27 to firmly engage inside the support rail 4, thus achieving an efficient and rapid installation effect; subsequently, firmly engage the limit wheel 6 on the outer wall of the support rail 4, and through the expansion and contraction force of the first spring 19, push the slider 17 to perform precise limit sliding on the outer wall of the second limiting rod 18, so that the limit wheel 6 is firmly fixed on the outer wall of the support rail 4; this mechanism not only ensures the firm engagement of the limit wheel 6, but also enables the support rail 4 to be flexibly adapted and installed according to the step board 1 of different widths; in addition, by rotating the threaded sleeve 21, the distance between multiple support rails 4 can be adjusted, thereby achieving precise adjustment of the length; this design not only improves the convenience and adaptability of installation, but also optimizes the configuration of the support rail 4, making the installation of the step board 1 more flexible and efficient, meeting different installation requirements.

[0036] Working principle: When in use, first, when the step board 1 is running, it will receive pressure and conduct the pressure to the support rail 4. At this time, the support rail 4 receives the pressure, and at the same time, the pressure will be conducted to the fixed box 8 through the connecting frame 7. At this time, the pressure will drive the first runner 11 to run on the guide rail. Since the pressure drives the first runner 11 to move, it will cause the first limiting rod 9 to slide limit inside the fixed box 8. At this time, the first limiting rod 9 drives the hinge block 12 above the sliding plate 10 to move. At this time, through the movement of the hinge block 12, it will push the two rotating plates 13 to rotate. At this time, through the movement of the rotating plates 13, it will drive the second runner 1501 to slide on the inner wall of the fixed box 8. At this time, through the movement of the second runner 1501, it will stretch the tension spring 1502, thereby reducing the pressure received by the step board 1, and then weakening the force on the roller 3 during operation, and then increasing the service life of the step board 1.

[0037] Secondly, when it is necessary to use the support structure according to step boards 1 of different widths, at this time, take out multiple support rails 4 and match them with the step board 1 to be installed. At this time, insert the insertion block 24 and the positioning rod 25 on one side of a support rail 4 into the inside of another support rail 4. At this time, the positioning rod 25 achieves the effect of rapid positioning. At this time, the elastic force of the second spring 26 will push the clamping block 27 to be clamped inside another support rail 4, thereby achieving the effect of rapid installation. At this time, then clamp the limiting wheel 6 on the outer wall of the support rail 4, and at the same time, the elastic force of the first spring 19 pushes the slider 17 to slide limit on the outer wall of the second limiting rod 18, thereby clamping the limiting wheel 6 on the outer wall of the support rail 4, and then achieving the effect of adapting and installing according to step boards 1 of different widths. At the same time, by rotating the threaded sleeve 21, the distance between multiple support rails 4 can be adjusted, and then the effect of length adjustment is achieved.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
