[0031] In order to more clearly illustrate the embodiments of the present invention, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained.

[0032] Embodiment 1:

[0033] As Figures 1 to 7 shown, the cleaning device for the guide rail in this embodiment includes a base 1, a frame 2, four horizontal rollers 3, two vertical rollers 4, and two lasers 5.

[0034] As Figure 2 shown, the base 1 in this embodiment is a plate-like structure, and mounting holes 10 are provided on the base 1 for fixed installation on the elevator car;

[0035] The frame 2 in this embodiment is vertically installed on the base 1, as Figure 3As shown in the figure, the cross-section of the frame 2 is a convex-shaped structure with an open bottom. The middle and lower parts of the frame 2 form a guide rail through groove 2-1. The left and right sides of the guide rail through groove 2-1 form a left mounting position 2-2 and a right mounting position 2-3. The middle and upper parts of the horizontal frame 2 form a vertical roller groove 2-4. Among them, the above-mentioned guide rail through groove 2-1 is used for the T-shaped guide rail 0 of the elevator to pass through.

[0036] The four horizontal rollers of this embodiment are respectively distributed and installed at the top and bottom of the frame. Specifically, horizontal rollers 3 are installed at both the top and bottom of the frame 2 and are distributed oppositely. The horizontally distributed rollers 3 are used to clamp the left and right side surfaces of the guide rail 0. Among them, as Figure 4 shown, the two horizontal rollers 3-1 at the top and bottom on the left side are installed at the left mounting position 2-2 of the frame through a left horizontal roller mounting bracket 6-1, and the two horizontal rollers 3-2 at the top and bottom on the right side are installed at the right mounting position 2-3 of the frame through a right horizontal roller mounting bracket 6-2. The left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2 are both U-shaped structures and are mirror-symmetrically distributed on both sides of the guide rail 0. The open sides of the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2 are respectively facing the left and right side surfaces of the guide rail 0.

[0037] Taking the installation of one of the horizontal rollers in this embodiment as an example for detailed description, the installation of other horizontal rollers is similar and will not be elaborated here. As Figure 7 shown, specifically taking the horizontal roller 3-2 at the top on the left side as an example, the axle 30 of the horizontal roller 3-2 is fixedly installed at the top of the left horizontal roller mounting bracket 6-1. A waist-shaped hole 20 is provided at the left mounting position 2-2 of the frame. The axle 30 passes through the waist-shaped hole 20 of the frame and is fixed to the frame 2 through common fixing parts such as a combination of a nut and a gasket 8. By moving the axle 30 in the waist-shaped hole 20 of the frame, the distance between the two horizontally distributed rollers is adjusted, so as to adapt to guide rails of different sizes such as 9, 10, and 16 mm. Among them, corresponding to the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2, left threaded parts 7-1 and right threaded parts 7-2 (such as screws or bolts) are provided on the left and right side walls of the frame 2 respectively. Each threaded part is located on the side of its corresponding horizontal roller facing away from the guide rail through groove 2-1. By screwing each threaded part with the frame 2 and abutting against its corresponding horizontal roller mounting bracket, the movement direction of each horizontal roller mounting bracket along the waist-shaped hole (i.e., the radial direction of the horizontal roller) is limited. Among them, the axial direction of the threaded part is parallel to the radial direction of the horizontal roller, and the threaded part and the elevator guide rail are used to limit the horizontal roller and its corresponding horizontal roller mounting bracket. Through the above structural design, the guide rail cleaning device of this embodiment can adapt to guide rails of different sizes such as 9, 10, and 16 mm.

[0038] At the top and bottom of the above-mentioned vertical roller groove 2-4, vertical rollers 4 are respectively installed. The vertical rollers 4 are used to clamp the inner side of the guide rail 0 located in the through groove of the guide rail.

[0039] In this embodiment, through the collaborative design of four horizontal rollers and two vertical rollers, the relative positions of the guide rail and the lasers on both sides thereof are fixed, ensuring the consistency and stability of the laser cleaning of the two sides of the guide rail 0 by the lasers 5 located on both sides of the through groove of the guide rail.

[0040] Specifically, as Figure 3 and Figure 6 shown, the two lasers 5 of this embodiment are respectively installed at the installation positions 21 on the left and right side walls of the frame 2 and penetrate through the through openings 60 of the left horizontal roller mounting frame 6-1 and the right horizontal roller mounting frame 6-2; as Figure 5 shown, the laser emission end 50 of the laser 5 faces the through groove 2-1 of the guide rail and is used to emit laser to the surface of the guide rail 0 for cleaning the surface of the guide rail 0; the two lasers 5 of this embodiment realize laser cleaning of the left and right side surfaces of the guide rail 0. Among them, the installation position 21 is an inclined structure, realizing the inclined installation of the laser 5 so that the laser emission end 50 is located at the bottom end of the laser 5, which can prevent the laser emission end from being damaged by dust accumulation or foreign objects.

[0041] The elevator of this embodiment adopts the above-mentioned cleaning device for the guide rail. The frame 2 is fixedly installed on the elevator car through the installation holes 10 of the base 1 and moves up and down in cooperation with the elevator car to realize the automatic cleaning of the elevator guide rail.

[0042] Embodiment 2:

[0043] The difference between the cleaning device for the guide rail in this embodiment and that in Embodiment 1 lies in:

[0044] As Figure 8 shown, the frame has a horizontal roller installation groove and a vertical roller installation groove. The groove frames I of the horizontal roller installation groove are distributed on the left and right sides of the through groove of the guide rail and are directly fixed on the frame without position adjustment. The vertical roller installation groove is located inside the through groove of the guide rail to form a convex-shaped structure with an open bottom; that is, the horizontal rollers and vertical rollers are directly installed on the frame, with a simple structure, but the distance between the relatively distributed horizontal rollers cannot be adjusted, and it can only be adapted to elevator guide rails with a fixed width to meet the requirements of different applications;

[0045] Among them, the laser emission end of the laser is located in the horizontal roller installation groove;

[0046] Other structures can refer to Embodiment 1.

[0047] The elevator of this embodiment adopts the cleaning device for the guide rail in this embodiment and can also realize the automatic cleaning of the elevator guide rail.

[0048] Example 3:

[0049] The difference between the cleaning device for guide rails in this embodiment and that in Embodiment 1 lies in:

[0050] The number of lasers can be adjusted according to actual application requirements, such as one, three, four, etc.; in addition, L-shaped guide rails can also be used; to meet the requirements of different applications;

[0051] Other structures can refer to Embodiment 1.

[0052] For the elevator in this embodiment, by using the cleaning device for guide rails in this embodiment, automatic cleaning of elevator guide rails can also be achieved.

[0053] Example 4:

[0054] The difference between the cleaning device for guide rails in this embodiment and that in Embodiment 1 lies in:

[0055] The laser can also be provided with an erasing mechanism with a spring before laser erasing according to actual application requirements, that is, an erasing mechanism with a spring is arranged on the frame to improve the efficiency of laser cleaning; among them, the erasing mechanism can refer to the prior art and will not be elaborated here, and any existing elastic erasing mechanism can be used;

[0056] Other structures can refer to Embodiment 1.

[0057] For the elevator in this embodiment, by using the cleaning device for guide rails in this embodiment, automatic cleaning of elevator guide rails can also be achieved.

[0058] The above is only a detailed description of the preferred embodiments and principles of the present invention. For those of ordinary skill in the art, according to the idea provided by the present invention, there will be changes in the specific implementation manners, and these changes should also be regarded as the protection scope of the present invention.
