[0031] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] Example 1:

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

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

[0035] In this embodiment, the frame 2 is vertically mounted on the base 1, such as Figure 3As shown, the cross-section of the frame 2 is a convex-shaped structure with an open bottom. The lower middle part of the frame 2 forms 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 upper middle part of the horizontal frame 2 forms a vertical roller groove 2-4. The guide rail through groove 2-1 is used for the T-shaped guide rail 0 of the elevator to pass through.

[0036] In this embodiment, four horizontal rollers are respectively 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 these horizontal rollers 3 are used to clamp the left and right surfaces of the guide rail 0. For example, Figure 4 As shown, the two horizontal rollers 3-1 at the top and bottom on the left side are mounted on the left mounting position 2-2 of the frame via the left horizontal roller mounting bracket 6-1, and the two horizontal rollers 3-2 at the top and bottom on the right side are mounted on the right mounting position 2-3 of the frame via the right horizontal roller mounting bracket 6-2; both the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2 are U-shaped structures, symmetrically distributed on both sides of the guide rail 0; the opening sides of both the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2 face the left and right surfaces of the guide rail 0, respectively;

[0037] This embodiment uses the installation of one horizontal roller as an example for detailed explanation; the installation of other horizontal rollers is similar and will not be repeated here. Figure 7 As shown, taking the horizontal roller 3-2 on the top left as an example, the axle 30 of the horizontal roller 3-2 is fixedly installed on the top of the left horizontal roller mounting bracket 6-1. The left mounting position 2-2 of the frame has a slotted hole 20. The axle 30 passes through the slotted hole 20 of the frame and is fixed to the frame 2 by common fasteners such as the combination of nuts and washers 8. By moving the axle 30 in the slotted hole 20 of the frame, the distance between the two oppositely distributed horizontal rollers can be adjusted, thereby adapting to different distances such as 9, 10, and 16 mm. The guide rails are of various sizes; the left and right side walls of the frame 2 are respectively provided with left threaded parts 7-1 and right threaded parts 7-2 (e.g., screws or bolts) corresponding to the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2. Each threaded part is located on one side of the guide rail through groove 2-1 opposite to its corresponding horizontal roller. By threading the threaded parts with the frame 2 and abutting against their respective horizontal roller mounting brackets, the horizontal roller mounting brackets are limited along the direction of movement of the oblong hole (i.e., the radial direction of the horizontal roller). The axial direction of the threaded parts is parallel to the radial direction of the horizontal rollers. The threaded parts and the elevator guide rails are used to limit the horizontal rollers and their corresponding horizontal roller mounting brackets. Through the above structural design, the guide rail cleaning device of this embodiment can be adapted to guide rails of different sizes such as 9, 10, and 16 mm.

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

[0039] This embodiment utilizes a coordinated design of four horizontal rollers and two vertical rollers to fix the relative position of the guide rail and the lasers on both sides, ensuring the consistency and stability of laser cleaning of the two sides of the guide rail by the lasers 5 located on both sides of the guide rail through groove.

[0040] Specifically, such as Figure 3 and Figure 6 As shown, in this embodiment, the two lasers 5 are respectively installed on the left and right side wall mounting positions 21 of the frame 2 and pass through the through openings 60 of the left horizontal roller mounting bracket 6-1 and the right horizontal roller mounting bracket 6-2; as Figure 5 As shown, the laser emitting end 50 of the laser 5 faces the guide rail through groove 2-1 and is used to emit laser light onto the surface of the guide rail 0 to clean the surface of the guide rail 0. In this embodiment, the two lasers 5 perform laser cleaning on the left and right sides of the guide rail 0. The mounting position 21 is an inclined structure, which allows the laser 5 to be installed at an angle so that the laser emitting end 50 is located at the bottom of the laser 5, which can prevent the laser emitting end from accumulating dust or foreign objects and being damaged.

[0041] In this embodiment, the elevator uses the aforementioned guide rail cleaning device. The frame 2 is fixedly installed on the elevator car through the mounting holes 10 of the base 1. It works in conjunction with the elevator car to move up or down, thereby achieving automatic cleaning of the elevator guide rails.

[0042] Example 2:

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

[0044] like Figure 8 As shown, the frame has horizontal roller mounting slots and vertical roller mounting slots. The slot frames I of the horizontal roller mounting slots are distributed on the left and right sides of the guide rail through slot and are directly fixed to the frame, and their positions cannot be adjusted. The vertical roller mounting slots are located inside the guide rail through slot to form a convex structure with an open bottom. That is, the horizontal rollers and vertical rollers are directly mounted on the frame. The structure is simple, but the spacing between the relatively distributed horizontal rollers cannot be adjusted. It can only be adapted to elevator guide rails of fixed width to meet the needs of different applications.

[0045] The laser emitting end of the laser is located in the horizontal roller mounting groove;

[0046] Other structures can be found in Example 1.

[0047] The elevator in this embodiment uses the guide rail cleaning device of this embodiment, which can also achieve automatic cleaning of the elevator guide rail.

[0048] Example 3:

[0049] The difference between the guide rail cleaning device in this embodiment and that in embodiment 1 is as follows:

[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 needs of different applications.

[0051] Other structures can be found in Example 1.

[0052] The elevator in this embodiment uses the guide rail cleaning device of this embodiment, which can also achieve automatic cleaning of the elevator guide rail.

[0053] Example 4:

[0054] The difference between the guide rail cleaning device in this embodiment and that in embodiment 1 is:

[0055] Depending on the actual application requirements, a spring-loaded wiping mechanism can be added to the laser before laser wiping, that is, a spring-loaded wiping mechanism can be set on the frame to improve the efficiency of laser cleaning; the wiping mechanism can refer to existing technology, which will not be elaborated here, and any existing elastic wiping mechanism is acceptable.

[0056] Other structures can be found in Example 1.

[0057] The elevator in this embodiment uses the guide rail cleaning device of this embodiment, which can also achieve automatic cleaning of the elevator guide rail.

[0058] The above description is only a detailed explanation of the preferred embodiments and principles of this utility model. For those skilled in the art, there may be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the protection scope of this utility model.
