[0034] The cleaning assembly includes a fixed shaft 8, which is fixedly connected to one side of the hanging plate 1. The fixed shaft 8 is circumferentially rotated and connected to a rotating plate 9. A pressure frame 10 is installed at one end of the rotating plate 9. The pressure frame 10 is L-shaped and is fixedly connected to a cleaning head 12 at one end away from the rotating plate 9. A torsion spring 14 is fixedly connected between the rotating plate 9 and the fixed shaft 8. During the movement of the hanging plate 1, the pressure frame 10 and the cleaning head 12 are also driven to move. The cleaning head 12 maintains contact with the surface of the elevator track under the action of the torsion spring 14, so that the cleaning head 12 can clean the elevator guide rail, thereby preventing dust from being deposited on the surface of the elevator guide rail for a long time and affecting the use of the roller 2.
[0035] Embodiment 2
[0036] Improved on the basis of embodiment 1: Refer to attached Figure 1-Figure 5 ,
[0037] In the present utility model, reference Figure 3 One end of the pressure frame 10 is fixedly connected with an insertion rod 11, and the insertion rod 11 is plugged into the rotating plate 9. A second spring 13 is fixedly connected between the pressure frame 10 and the rotating plate 9. Through the setting of the insertion rod 11, the distance between the pressure frame 10 and the rotating plate 9 can be adjusted to avoid collision of the cleaning head 12.
[0038] In particular, two through slides are provided on one side of the hanging plate 1, and the two slides are inclined and symmetrically arranged. Anti-jumping components are arranged in the slides to prevent the hanging plate 1 from jumping. The anti-jumping components include a slider 15, and the slider 15 is slidably connected in the slide. A threaded rod 16 is fixedly connected to one side of the slider 15. The circumferential thread of the threaded rod 16 is connected to a clamping nut 17 for positioning the slider 15. An anti-jumping wheel 18 is rotatably connected to the side of the slider 15 away from the clamping nut 17. The anti-jumping wheel 18 is located below the roller 2. The anti-jumping wheel 18 and the roller 2 are respectively located on both sides of the elevator guide rail, thereby forming a clamping state for the elevator guide rail, preventing the hanging plate 1 from jumping during use, and improving the safety of use.
[0039] It should be noted that the roller 2 includes an inner ring 20, a bearing 21 is installed on the circumferential outer wall of the inner ring 20, an outer ring 22 is installed on the circumferential outer wall of the bearing 21, a limiting shaft 19 is inserted in the inner ring 20, the limiting shaft 19 passes through the hanging plate 1 and is threadedly connected with a fixing nut 25 for fixing the inner ring 20, a plurality of clamping blocks 24 for limiting the bearing 21 are installed on the circumference of the outer ring 22, and a rubber ring 23 is fixedly connected to the circumferential outer wall of the outer ring 22. The rubber ring 23 can increase the noise reduction effect of the roller 2 during rolling.
[0040] In the utility model, one side of the hanging plate 1 is fixedly connected to two guide blocks 4, and L-shaped top frames 5 are slidably connected in the two guide blocks 4. One end of the top frames 5 is fixedly connected to a clamping head 6, and the two clamping heads 6 are respectively located on one side of the two fixing nuts 25 and used in conjunction with the fixing nuts 25. A supporting member for supporting the two top frames 5 is provided between the two top frames 5, and the supporting member is a first spring 7, which is fixedly connected between the two top frames 5. After the roller 2 is installed, the two top frames 5 are pushed by the first spring 7 in the middle, and then the clamping head 6 is driven to clamp together with the two fixing nuts 25 respectively, thereby avoiding loosening of the fixing nuts 25 and improving the stability of the roller 2 when used.
[0041] In particular, the hanging plate 1 is L-shaped, and a group of fixing holes 3 for fixing the hanging plate 1 are opened at the bottom of the hanging plate 1. The fixing holes 3 are all waist-shaped holes, and the fixing holes 3 are used for installing and fixing the hanging plate 1.
[0042] The use process and working principle of the technical solution of this utility model are as follows:
[0043] In the present application, when in use, the hanging plate 1 is fixed above the car door through the fixing hole 3, and the two rollers 2 are installed above the elevator guide rails, keeping the rollers 2 in contact with the top of the elevator guide rails, and then adjusting the two anti-jumping wheels 18. When adjusting, slide the slider 15, and the slider 15 slides in the slideway. Since the slideway is inclined, the anti-jumping wheel 18 can approach the elevator guide rail. After the anti-jumping wheel 18 contacts the elevator guide rail, the clamping nut 17 is locked, and the clamping nut 17 is in conflict with the hanging plate 1, thereby completing the fixation of the anti-jumping wheel 18. The anti-jumping wheel 18 and the roller 2 are respectively located on both sides of the elevator guide rail, thereby forming a clamping force on the elevator guide rail. The state prevents the hanging plate 1 from jumping during use. When the hanging plate 1 is moving, it also drives the pressure frame 10 and the cleaning head 12 to move. The cleaning head 12 keeps in contact with the elevator track surface under the action of the torsion spring 14, so that the cleaning head 12 can clean the elevator guide rail, avoiding the dust accumulation on the surface of the elevator guide rail after long-term use and affecting the use of the roller 2. After the roller 2 is installed, the two top frames 5 are pushed by the first spring 7 in the middle, thereby driving the clamping head 6 to clamp together with the two fixing nuts 25 respectively, avoiding the loosening of the fixing nuts 25 and improving the stability of the roller 2.
