Description

Technical Field

[0001] This utility model relates to an escalator guardrail panel, and more particularly to an installation mechanism based on an inclined handrail guardrail panel. Background Technology

[0002] Currently, there are three methods for installing the handrail and guardrail panels of inclined escalators. The first method, as shown in patent 202022357402.0, involves installing welded screws on the inner side of the skirt panel to connect an elastic pressure plate. This allows the elastic pressure plate to work with the skirt panel after the guardrail panel is inserted, squeezing and limiting the guardrail panel from both sides, while the welded screws provide support. Simultaneously, the upper end of the guardrail panel is fastened to the handrail frame, thus limiting the guardrail panel from both top and bottom. However, this installation method has drawbacks. Firstly, because the guardrail panel is not completely fixed to the skirt panel and handrail frame after installation, it is prone to sliding, shifting, or even falling off under external forces, resulting in poor installation stability. Secondly, the connection between the skirt panel and the welded screws has relatively low rigidity, making the welded screws prone to falling off under pressure and impact from the guardrail panel, further reducing the installation stability of the guardrail panel.

[0003] The second installation method, as shown in patent 201110295009.6, involves installing a support frame on the escalator truss chord inside the skirt panel. This allows the support frame to work in conjunction with the skirt panel to limit the movement of the wall panel. While this method improves the connection stability of the support frame compared to the first method, it also has drawbacks. Firstly, the support frame can affect the path of the handrail belt after installation, and there is a risk of it rubbing against the handrail belt. Secondly, drilling holes in the escalator truss chord will reduce its strength, thereby increasing the possibility of deformation and damage to the escalator truss chord.

[0004] The third installation method, as shown in patent 200810107291.9, involves directly installing a mounting bracket on the inside of the apron panel and then bolting the inside of the wall panel to the mounting bracket to achieve its fixing function. While this installation method can achieve a rigid fixation of the wall panel, it also means that the wall panel cannot be directly removed from the outside, thus increasing the difficulty for workers to install and remove it.

[0005] Therefore, existing escalator handrails and wall panels cannot simultaneously possess the characteristics of good installation stability and easy disassembly. Utility Model Content

[0006] The purpose of this invention is to provide an installation mechanism based on a sloping handrail wall panel. It simultaneously offers the advantages of good installation stability and ease of assembly and disassembly.

[0007] The technical solution of this utility model is as follows: An installation mechanism based on a slanted handrail wall panel includes a wall panel, a skirt panel, and a handrail frame. The handrail frame and the skirt panel are located on the upper and lower sides of the wall panel and connected to the wall panel. A fixing nut is fixedly connected to the skirt panel. The bottom of the wall panel is provided with a connecting hole that matches the fixing nut. A fixing screw is provided in the connecting hole. One end of the fixing screw passes through the wall panel and the skirt panel in sequence and is threaded to the fixing nut. A first reinforcing rib is fixedly connected to the wall panel above the fixing screw. The bottom of the first reinforcing rib is in contact with the upper surface of the skirt panel and is used to limit the rotation of the wall panel.

[0008] In the aforementioned installation mechanism based on a sloping handrail wall panel, the apron panel is provided with a fastening opening, and the fixing nut is a snap-fit ​​nut that is fastened to the apron panel through the fastening opening.

[0009] In the aforementioned installation mechanism based on a sloping handrail wall panel, the fixing screw is a countersunk screw, and the connecting hole is a countersunk hole that mates with the countersunk screw.

[0010] In the aforementioned installation mechanism based on a sloping handrail wall panel, the handrail frame includes a handrail cover plate reinforcing rib, and a handrail cover plate and a pressure plate spring are respectively connected to the handrail cover plate reinforcing rib. One end of the handrail cover plate and the pressure plate spring extends to the outside of the handrail cover plate reinforcing rib and forms a fastening groove. The upper end of the wall panel is fastened and connected in the fastening groove.

[0011] In the aforementioned installation mechanism based on the inclined handrail wall panel, the upper end of the wall panel is connected to the fastening groove via a second reinforcing rib. The first and second reinforcing ribs have the same structure, both including a reinforcing plate with a C-shaped cross section. A connecting piece is connected to the outside of the reinforcing plate, and the connecting piece and the wall panel are detachably connected.

[0012] In the aforementioned installation mechanism based on the inclined handrail wall panel, a gap is formed between the second reinforcing rib and the inner end face of the fastening groove, allowing the second reinforcing rib to slide inward.

[0013] In the aforementioned installation mechanism based on the inclined handrail wall panel, the connecting piece and the wall panel are connected to each other by a screw assembly. The screw assembly includes a screw fixedly connected to the inner side of the wall panel, and one end of the screw passes through the connecting piece and is threaded with a second nut.

[0014] Compared with the prior art, this utility model has the following characteristics:

[0015] (1) This utility model installs a fixing nut on the skirt board and connects a fixing screw to the bottom of the wall panel through a connecting hole, so that the fixing screw and the fixing nut can fix the skirt board and the wall panel through a threaded connection. This improves the installation stability of the wall panel and allows the workers to directly load and unload the wall panel from the outside, which effectively reduces the difficulty of loading and unloading the wall panel and does not occupy the installation space of the inner escalator truss chord. On this basis, by setting a first reinforcing rib on the inner side of the wall panel and fitting it to the upper end of the skirt board, the skirt board can also support the wall panel after installation and the weight of the wall panel can be borne by the entire skirt board, improving the support stability of the wall panel and reducing the possibility of the skirt board being deformed by force at the fixing nut.

[0016] (2) By limiting the connection structure between the handrail and the wall panel, on the one hand, the structural strength of the wall panel can be improved by the cooperation of the first and second reinforcing ribs, and the possibility of deformation of the wall panel under stress can be reduced; on the other hand, the second reinforcing rib can also be used to improve the fastening stability of the handrail and the wall panel, and make it convenient for the operator to remove the fixing screws and slide the wall panel upward to remove it, thus improving the ease of disassembling the wall panel.

[0017] Therefore, this utility model can simultaneously have the characteristics of good installation stability and convenient disassembly and assembly. Attached Figure Description

[0024] Example. An installation mechanism based on a sloping handrail wall panel, configured as follows: Figure 1 As shown, the device includes a wall panel 1, an apron panel 2, and a handrail frame 3. The handrail frame 3 and the apron panel 2 are located on the upper and lower sides of the wall panel 1 and are connected to the wall panel 1. A fixing nut 4 is fixedly connected to the top of the apron panel 2. The bottom of the wall panel 1 is provided with a connecting hole that matches the fixing nut 4. A fixing screw 5 is provided in the connecting hole. One end of the fixing screw 5 passes through the wall panel 1 and the apron panel 2 in sequence and is threaded to the fixing nut 4. A first reinforcing rib 6 is fixedly connected to the wall panel 1 above the fixing screw 5. The bottom of the first reinforcing rib 6 is in contact with the upper end face of the apron panel 2 and is used to limit the rotation of the wall panel 1.

[0025] The apron panel 2 is provided with a fastening opening 201, and the fixing nut 4 is a snap-fit ​​nut that is fastened to the apron panel 2 through the fastening opening 201; thus, the fixing nut 4 does not require the operator to support it by hand when the fixing screw 5 is screwed in, making the installation operation convenient.

[0026] The fixing screw 5 is a countersunk screw, and the connecting hole is a countersunk hole that mates with the countersunk screw.

[0027] The handrail frame 3 includes a handrail cover plate reinforcing rib 301, and a handrail cover plate 302 and a pressure plate spring 303 are respectively connected to the handrail cover plate reinforcing rib 301. One end of the handrail cover plate 302 and the pressure plate spring 303 extends to the outside of the handrail cover plate reinforcing rib 301 and forms a fastening groove 7. The upper end of the wall panel 1 is fastened and connected in the fastening groove 7.

[0028] Both the handrail cover plate 302 and the pressure plate spring 303 are thin metal sheets. The handrail cover plate 302 and the pressure plate spring 303 are located on the upper and lower sides of the handrail cover plate reinforcing rib 301 and are connected to the handrail cover plate reinforcing rib 301 by screws. The connecting screws of the handrail cover plate 302 and the pressure plate spring 303 are staggered along the length direction of the handrail cover plate reinforcing rib 301.

[0029] The upper end of the wall panel 1 is connected to the fastening groove 7 via the second reinforcing rib 8. The first reinforcing rib 6 and the second reinforcing rib 8 have the same structure, both including a reinforcing plate 9 with a C-shaped cross section. A connecting piece 10 is connected to the outside of the reinforcing plate 9, and the connecting piece 10 and the wall panel 1 are detachably connected.

[0030] A gap is formed between the inner end face of the second reinforcing rib 8 and the snap-fit ​​groove 7, allowing the second reinforcing rib 8 to slide inward.

[0031] The connecting piece 10 and the wall panel 1 are connected to each other by a screw assembly. The screw assembly includes a screw 11 fixedly connected to the inner side of the wall panel 1. One end of the screw 11 passes through the connecting piece 10 and is threaded with a second nut 12.

[0032] The inner side of the middle part of the wall panel 1 is provided with a third reinforcing rib 13, and the shape of the third reinforcing rib 13 is the same as that of the first reinforcing rib 6 and the second reinforcing rib 8.

[0033] The working principle of this utility model is as follows: When installing the wall panel 1, first insert the second reinforcing rib 8 at the upper end of the wall panel 1 into the fastening groove 7. Then, move the wall panel 1 downwards so that the bottom surface of the first reinforcing rib 6 is in contact with the top surface of the skirt panel 2, while aligning the connecting hole at the bottom of the wall panel 1 with the fixing nut 4 on the skirt panel 2. After the wall panel 1 is in place, the operator then passes the fixing screw 5 through the wall panel 1 and the skirt panel 2 and screws it into the fixing nut 4, thereby fixing the wall panel 1 and the skirt panel 2 by tightening the fixing screw 5 and the fixing nut 4 together.

[0034] When it is necessary to remove the wall panel 1, the operator first unscrews the fixing screw 5 to release the wall panel 1 from the fixing, then lifts the wall panel 1 upwards to separate the bottom of the wall panel 1 from the skirt panel 2, then rotates the wall panel 1 outwards and pulls it out in the opposite direction to remove the wall panel 1.
