Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of passenger conveying device, and in particular to a cover plate for escalator renovation. BACKGROUND

[0002] As a widely used transportation public equipment in public places, the escalator will have different degrees of wear and aging problems after long-term use, and generally needs to be updated and renovated. It is usually required to minimize the impact on the on-site peripheral decoration parts, or even not to affect them. The diversity and complexity of the renovation site greatly increase the difficulty of designing to meet the above requirements.

[0003] In the existing patent scheme for escalator renovation, it is proposed that the original peripheral decoration parts of the escalator can be retained, but there is no specific details or specific scheme on how to match or connect the renovated escalator decoration parts with the original peripheral decoration parts. Especially between different brands and different models of escalators, due to size and structural differences, the installation of the cover plate often needs to be adjusted on site, and the existing technology lacks effective adjusting mechanism to adapt to such differences. In addition, the existing technology also fails to fully consider how to minimize the impact on the on-site peripheral decoration parts, resulting in the need to remove or replace the original decoration parts in a large range during the renovation process, increasing the complexity and cost of the project. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a cover plate for escalator renovation, which can adapt to different installation environments, is easy to adjust, and minimizes the impact on the original decoration parts, so as to meet the actual needs of escalator renovation projects.

[0005] To solve the above technical problems, the present application provides a cover plate for escalator renovation, which comprises a body cover plate, a transverse sub-cover plate, a side guard plate, a support frame and a plurality of bolt fasteners, wherein the transverse sub-cover plate is an "L"-shaped bending structure, and the support frame is fixedly connected to the first bending edge of the transverse sub-cover plate through a transverse adjusting device.

[0006] Preferably, the side guard plate is fixedly connected to the second bending edge of the transverse sub-cover plate through a longitudinal adjusting device.

[0007] Preferably, the support frame is a "T"-shaped tree branch structure, the first support surface of the support frame is fixedly connected to the body cover plate through a first bolt, the transverse adjusting device comprises a second bolt and a first waist hole provided on the transverse sub-cover plate, and the second support surface of the support frame is fixedly connected to the first bending edge of the transverse sub-cover plate through the second bolt and the first waist hole.

[0008] Preferably, the longitudinal adjusting device comprises a third bolt and a second waist hole on the side panel, and the side panel is fixedly connected to the second bending edge of the transverse auxiliary cover plate through the third bolt and the second waist hole.

[0009] Preferably, the outer side of the body cover plate is in a "C" type bending structure, and the bottom bending edge of the "C" type bending structure is tightly attached to the transverse auxiliary cover plate.

[0010] Preferably, the third bolt is a countersunk screw.

[0011] Preferably, the transverse adjusting device is at least one.

[0012] Preferably, the longitudinal adjusting device is at least one.

[0013] Compared with the prior art, the cover plate structure of the present application is decoupled into three groups of independent structures assembled together; the body cover plate is the main structure, the transverse auxiliary cover plate can be adjusted in the horizontal direction, and the side panel can be adjusted in the vertical direction. The horizontal width and the vertical height of the cover plate of the present application can be freely adjusted, so that the cover plate has a larger coverage. By using the cover plate of the present application, the original peripheral decoration can be more completely matched, the damage to the site is greatly reduced, and the standardization of the product is improved.

The present application can also be implemented or applied through different specific embodiments, and each detail in the present specification can be applied based on different viewpoints, and various modifications or changes can be made without departing from the general design idea of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. The following exemplary embodiments of the present application can be implemented in various forms, and should not be interpreted as being limited to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application complete and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art. Example

[0018] like Figure 1 As shown, a preferred embodiment of a cover plate for escalator renovation and upgrading is illustrated, including a main cover plate 1, a transverse sub-cover plate 2, a side guard plate 3, a support frame 4, and a first bolt 51, a second bolt 52, and a third bolt 53.

[0019] The outer side of the main cover plate 1 has a "C"-shaped bend structure 11. The bottom bend of the "C"-shaped bend is tightly attached to the transverse sub-cover plate. This design makes the main cover plate 1 and the transverse sub-cover plate 2 form a stable connection, ensuring the flatness of the cover plate surface.

[0020] The transverse sub-cover plate 2 has an "L"-shaped bending structure. The transverse sub-cover plate 2 includes a first bending edge 21 and a second bending edge 22. The first bending edge 21 is connected to the support frame 4, and the second bending edge 22 is connected to the side guard plate 3. This "L"-shaped structure design allows the transverse sub-cover plate to provide support in both horizontal and vertical directions simultaneously.

[0021] The support frame 4 has a "T"-shaped tree-like branch structure with a first support surface 41 and a second support surface 42. This tree-like branch structure design increases the load-bearing capacity of the support frame while reducing the overall weight. The support surface 41 is fixed to the main cover plate 1 by a first bolt 51, ensuring that the main cover plate 1 can be stably installed on the support frame 4. The second support surface 42 is fixedly connected to the first bent edge 21 of the transverse sub-cover plate by a transverse adjustment device. The transverse adjustment device includes a second bolt 52 and a first waist hole 211 provided on the transverse sub-cover plate; the second support surface 42 of the support frame is fixedly connected to the first bent edge 21 of the transverse sub-cover plate 2 by the second bolt 52 and the first waist hole 211.

[0022] The lateral adjustment device allows the lateral sub-cover plate to be adjusted in the horizontal direction to accommodate escalators of different sizes, improving the versatility and adaptability of the cover plate. At least one lateral adjustment device can be provided, and the number can be increased as needed to enhance connection stability and adjustment flexibility.

[0023] The side guard plate 3 is fixedly connected to the second bent edge 22 of the transverse sub-cover plate via a longitudinal adjustment device. The longitudinal adjustment device includes a third bolt and a second slotted hole 31 on the side guard plate 3. The side guard plate is fixedly connected to the second bent edge 22 of the transverse sub-cover plate via the third bolt and the second slotted hole 31. The design of the second slotted hole 31 allows the side guard plate 3 to be adjusted in the longitudinal direction to accommodate escalators of different heights, further improving the versatility of the cover plate. At least one longitudinal adjustment device can be provided, and the number can be increased as needed.

[0024] The second bend 22 of the "L" shape of the transverse sub-cover plate contains multiple countersunk hole structures 221.

[0025] The first mounting surface of the side guard plate 3 has a vertical elongated hole 31. The first mounting surface of the side guard plate 3 is in close contact with the inner side of the second bent edge 22 of the transverse sub-cover plate 2 and is fixed by countersunk screws 53. The use of countersunk screws allows the screw head to be embedded in the side guard plate without forming a protrusion on the surface, ensuring the flatness and aesthetics of the outer surface of the cover plate, while avoiding the safety hazard of the screw head scratching or tripping pedestrians.

[0026] In the cover plate structure, the horizontal sub-cover plate 2 adjusts its horizontal width through the first waist hole 211 on its first bent edge 21, and the side guard plate 3 adjusts its vertical height through its second waist hole 31, so that the finally updated cover plate can completely cover the boundary of the original staircase's outer decorative parts 6 without producing any unsightly gaps.

[0027] In actual installation, the support frame 4 is first fixed to the main cover plate 1 with the first bolt 51. Then, the transverse sub-cover plate 2 is connected to the support frame 4 through the transverse adjustment device. After adjusting the transverse position, the second bolt 52 is tightened. Next, the side guard plate is connected to the transverse sub-cover plate through the longitudinal adjustment device. After adjusting the longitudinal position, the third bolt 53 is tightened. This installation method is simple and quick, and allows for fine-tuning during installation to adapt to the actual site conditions.

[0028] This invention, through the combined structure of a main cover plate, a transverse secondary cover plate, side guard plates, and a support frame, along with the coordinated use of transverse and longitudinal adjustment devices, allows the cover plate's coverage area to be freely adjusted in both horizontal and vertical directions, accommodating various dimensions of the original structure during escalator renovation. Compared to existing technologies, the cover plate structure of this invention eliminates the need to damage existing exterior decorative components during escalator upgrades, significantly reducing the impact on the original building environment. It also improves the standardization of the renovated product, reduces renovation costs, and enhances renovation efficiency. Furthermore, the combination of the "L"-shaped bent transverse secondary cover plate and the "T"-shaped tree-like branch support frame, along with the adjustable mechanism featuring a waist-hole design, makes cover plate installation more flexible. This allows for precise matching of dimensional differences between the original and new escalators, achieving a perfect connection between the renovated escalator decorative components and the original exterior decorative components.

[0029] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
