Description

Technical Field

[0001] This application relates to the field of escalator technology, and in particular to an escalator step. Background Technology

[0002] The treads are the key components of escalators that directly carry passengers and enable vertical transport of people. Currently, the treads of escalator steps are usually molded as a single piece, which initially ensures the strength and stability of the steps and meets basic load-bearing requirements thanks to the overall structure.

[0003] However, problems become apparent over time. The tread surface is in direct contact with passengers and bears the main weight, and is under high load for a long time. Under the frequent stepping, friction, and impact of heavy objects, it is very easy to wear and damage. In places with high traffic such as shopping malls and subway stations, the escalator runs for a long time, and the tread surface may show wear, scratches, or even local dents and cracks in a short period of time.

[0004] When the tread is damaged, due to its one-piece molding design, it is impossible to repair or replace only the tread; the entire step must be replaced. This method of maintenance, in terms of resource utilization and environmental protection, discards the entire step due to tread damage, resulting in resource waste and contradicting the principles of sustainable development. Utility Model Content

[0005] To facilitate the individual replacement, repair, or cleaning of the treads and reduce the waste of resources caused by replacing the entire step due to tread damage, this application provides an escalator step.

[0006] The escalator step provided in this application adopts the following technical solution:

[0007] An escalator step includes a support frame, on which a tread and a riser are provided. The tread is detachably mounted on the support frame. The support frame is provided with a mounting panel for mounting the tread. A guide post is provided on the tread. The mounting panel is provided with a slot for inserting the guide post. A locking device for locking the guide post is fixedly connected to the mounting panel.

[0008] By adopting the above technical solution, the tread can be detachably installed on the bracket, which facilitates the individual replacement, repair or cleaning of the tread and reduces the waste of resources caused by replacing the entire step due to tread damage.

[0009] By connecting the guide posts on the support frame with the slots on the mounting panel and locking the guide posts with a locking device, a stable connection between the tread and the support frame is achieved, ensuring the structural stability and safety of the escalator steps during use.

[0010] Optionally, the locking device includes a locking piece slidably disposed on the mounting panel, the locking piece being located on the side of the mounting panel opposite to the tread surface;

[0011] The guide post has an annular groove, and the locking plate has a through groove for the guide post to pass through and a limiting groove communicating with the through groove. The guide post passes through the through groove, and the locking plate can move to drive the limiting groove to engage with the annular groove, thereby preventing the guide post from disengaging from the slot.

[0012] By adopting the above technical solution, an annular groove is opened on the guide post, and a through groove and a limiting groove are set on the locking plate. By moving the locking plate, the limiting groove is engaged with the annular groove, which can effectively limit the guide post from disengaging from the slot, thereby preventing the tread from loosening or falling off and enhancing the reliability of tread installation.

[0013] Optionally, a pad is provided on the locking piece at the position corresponding to the limiting groove, and the pad is located on the side of the locking piece away from the mounting panel;

[0014] When the locking piece moves to the limiting groove and engages with the annular groove, the pad extends into the annular groove and presses against its groove wall, thereby pressing the tread surface onto the mounting panel.

[0015] By adopting the above technical solution, a pad is set on the locking plate at the position corresponding to the limiting groove. When the locking plate moves to the locking groove and engages with the ring groove, the pad extends into the ring groove and presses against its groove wall, further pressing the tread surface onto the mounting panel. This not only enhances the tightness of the connection between the tread surface and the mounting panel, but also reduces vibration and noise during operation.

[0016] Optionally, the pad has a guide slope on the side facing the through groove so that the pad can be inserted into the annular groove.

[0017] By adopting the above technical solution, a guide slope is set on the side of the pad block facing the through groove. During the process of the locking piece moving to extend the pad block into the annular groove, the guide slope can play a guiding role, so that the pad block can be extended into the annular groove more smoothly, improving the convenience of operation and assembly efficiency.

[0018] Optionally, a rack is fixedly connected to the locking plate, a gear that meshes with the rack is rotatably connected to the mounting panel, and a limiting mechanism for restricting the rotation of the gear is provided on the mounting panel.

[0019] By adopting the above technical solution, a rack is fixedly connected to the locking plate, and a gear that meshes with the rack is rotatably connected to the mounting panel. The rotation of the gear drives the rack and the locking plate to move, thereby realizing the locking or unlocking operation of the locking plate on the guide post. This transmission method makes the operation more labor-saving and precise, and facilitates the installation and removal of the tread surface by the staff.

[0020] The mounting panel is equipped with a limiting mechanism to restrict gear rotation. This mechanism prevents the gear from rotating accidentally and causing the locking plate to move after the locking plate locks the guide post, thus ensuring the stability of the tread installation.

[0021] Optionally, the limiting mechanism includes a spline shaft axially slidably disposed on the gear; a through hole is provided on the mounting panel, and a spline groove is provided on the inner wall of the through hole; the spline shaft can move axially to engage or disengage with the spline groove; an elastic element is provided between the gear and the spline shaft, and the elastic element applies a pre-thrust force to the spline shaft to keep it engaged with the spline groove.

[0022] By adopting the above technical solution, the spline shaft in the limiting mechanism is axially slidably mounted on the gear. A through hole is opened on the mounting panel and a spline groove is provided on the inner wall of the through hole. The spline shaft can move axially to engage or disengage with the spline groove. This structure can reliably limit the rotation of the gear. When the spline shaft engages with the spline groove, the gear cannot rotate, thereby ensuring that the locking plate is fixed in position and the tread is installed stably.

[0023] An elastic element is installed between the gear and the splined shaft. The elastic element applies a pre-push force to the splined shaft to keep it engaged with the spline groove, which can prevent the splined shaft from accidentally disengaging from the spline groove, improve the reliability of the limit mechanism, and ensure the safety of the escalator steps during use. In addition, it also allows the operator to easily separate the splined shaft from the spline groove by pressing the splined shaft. By rotating the splined shaft, the locking plate is moved under the action of the gear and rack, so as to achieve the locking and unlocking effect.

[0024] Optionally, the tread surface is provided with a relief hole aligned with the through hole, and a sealing cap is detachably installed on the tread surface within the relief hole.

[0025] By adopting the above technical solution, the tread surface is provided with a clearance hole aligned with the through hole, and a sealing cover can be detachably installed in the clearance hole. The sealing cover can prevent dust, debris and other objects from entering the through hole, avoid affecting the fit between the spline shaft and the spline groove, and ensure the normal operation of the limit mechanism. At the same time, the detachable sealing cover also facilitates the cleaning and maintenance of the inside of the through hole.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The escalator treads are designed for easy and quick replacement when they are worn or damaged, reducing the waste of resources caused by replacing the entire tread due to tread damage.

[0028] 2. Through the insertion and engagement of the guide column and the slot, and the locking of the locking plate in the locking assembly with the ring groove on the guide column, plus the pressing effect of the pad, multiple stable connections between the tread and the mounting panel are achieved, effectively avoiding problems such as loosening and shaking of the tread during use, and improving the safety and stability of the escalator operation;

[0029] 3. The clearance holes and removable sealing caps on the tread surface can prevent dust, debris and other contaminants from entering the through holes, protect the limiting mechanism, and facilitate cleaning and maintenance. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0041] This application discloses an escalator step in its embodiments. For example... Figure 1 , Figure 2 as well as Figure 3 The escalator steps include a support frame 10, on which treads 11 and risers 12 are provided. The support frame 10 serves as the main load-bearing structure and has a mounting panel 13 for installing the treads 11. Guide posts 14 are fixed on the treads 11, and the mounting panel 13 has slots 15 corresponding to the positions of the guide posts 14. During installation, the initial positioning and installation of the treads 11 are completed by aligning the guide posts 14 on the treads 11 and inserting them into the slots 15.

[0042] like Figure 4 and Figure 5 To reliably lock the initially installed tread 11 onto the mounting panel 13, this invention provides a dedicated locking device 20. This locking device 20 includes a locking piece 21 slidably disposed on the back of the mounting panel 13, i.e., on the side opposite to the tread 11. An annular groove 24 is formed at the end of the guide post 14. The locking piece 21 has a through groove 22 and a limiting groove 23 communicating with the through groove 22, wherein the through groove 22 allows the guide post 14 to pass through, and the limiting groove 23 engages with the annular groove 24.

[0043] Once the tread 11 is in place, the guide post 14 passes through the through groove 22 on the locking plate 21.

[0044] When locking, the locking piece 21 is moved horizontally, causing the limiting groove 23 on it to move toward and engage with the annular groove 24. Since the groove wall of the limiting groove 23 is engaged in the annular groove 24, mechanical interference is formed in the vertical direction, which effectively restricts the guide post 14 from disengaging from the slot 15 and achieves the fixation of the tread surface 11.

[0045] To further enhance the fixing effect and eliminate assembly gaps, a pad 30 is provided on the locking piece 21 at the position corresponding to the limiting groove 23. The pad 30 is located on the side of the locking piece 21 facing away from the mounting panel 13. When the locking piece 21 moves to the position where the limiting groove 23 engages with the annular groove 24, the pad 30 also extends into the annular groove 24 and abuts against the groove wall at the end of the annular groove 24. This is equivalent to applying a pressing force towards the tread surface 11, thereby pressing the tread surface 11 tightly onto the mounting panel 13 and preventing it from shaking or making noise during operation. To facilitate the smooth sliding of the pad 30 into the annular groove 24, a guide ramp 31 is provided on the side facing the inlet of the through groove 22.

[0046] like Figure 4To control the movement of the locking plate 21 more effortlessly and precisely, a rack 40 is fixedly connected to the locking plate 21, and a gear 41 that meshes with the rack 40 is rotatably connected to the mounting panel 13 via a rotating shaft. By rotating the gear 41, the rack 40 can be driven, which in turn drives the locking plate 21 to move in a straight line, making operation more convenient.

[0047] like Figure 6 , Figure 7 as well as Figure 8 To prevent the gear 41 from rotating unexpectedly under equipment vibration and causing the locking plate 21 to loosen, a limiting mechanism 50 is provided on the mounting panel 13. This limiting mechanism 50 includes a splined shaft 51, which is axially slidably mounted on the gear 41 via a spline engagement, and rotates synchronously with the gear 41. A through hole 52 is provided on the mounting panel 13, and the inner wall of the through hole 52 is provided with a spline groove 53 that matches the splined shaft 51. The splined shaft 51 can move axially to engage or disengage with the spline groove 53.

[0048] like Figure 8 and Figure 9 An elastic element 54 is provided between the gear 41 and the spline shaft 51. In this embodiment, the elastic element 54 is a spring, which always applies a pre-push force to the spline shaft 51 to make it embed into the spline groove 53. Specifically, a convex ring is provided on the spline shaft 51, and the spring is sleeved on the spline shaft 51, with the spring located between the gear 41 and the convex ring. A retaining ring is installed at one end of the spline shaft 51 that passes through the gear 41 to prevent the spline shaft 51 from disengaging from the gear 41.

[0049] When the spline shaft 51 engages with the spline groove 53 under the action of elastic force, the gear 41 cannot rotate, thus achieving self-locking. When adjustment is required, the spline shaft 51 is pressed down through the clearance hole 60, and the spline shaft 51 overcomes the elastic force and disengages from the spline groove 53. Then, the spline shaft 51 is rotated, and the engagement of the gear 41 and rack 40 drives the locking piece 21 to move, adjusting the relative position of the locking piece 21 and the guide post 14.

[0050] To facilitate operator access to and operation of the limiting mechanism 50, a clearance hole 60 is provided on the tread surface 11 directly opposite the through hole 52. In the non-maintenance state, the clearance hole 60 is closed by a removable sealing cover 61 to maintain the integrity of the tread surface 11.

[0051] The implementation principle of this application embodiment is as follows: First, the guide post 14 of the tread 11 is aligned with the slot 15 and inserted, so that the guide post 14 passes through the slot 15 and extends into the through groove 22 of the locking piece 21. By pressing the spline shaft 51, it is disengaged from the spline groove 53. Then, the spline shaft 51 is rotated, causing the locking piece 21 to slide and the limiting groove 23 to engage with the annular groove 24. At the same time, the pad 30 extends into the annular groove 24 under the guidance of the guide inclined surface 31 and presses against the groove wall, thereby achieving the pressing and fixing of the tread 11. After releasing the spline shaft 51, under the action of the spring, the spline shaft 51 and the spline groove 53 cooperate to prevent the gear 41 from rotating accidentally.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
