[0012] As a preferred guide rail for elevator maintenance of the utility model, the cleaning mechanism includes a cleaning plate and bristles, the bristles are located on the side of the cleaning plate close to the slide groove, and the cleaning plate is fixedly mounted on the bottom of the slide block by bolts.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model adds a fill-light mechanism inside the slide rail, uses an LED flashlight as a light source, and cooperates with a light guide strip to effectively disperse the light source to each fill-light hole in the slide groove and illuminate downward at a specific angle, which not only provides a good fill-light effect for the slider and the inner end surface of the slide groove, improves the visibility of the maintenance work, but also avoids the light source from directly shining into the eyes of the maintenance personnel, thereby improving the safety and accuracy of the maintenance.

[0015] 2. The utility model enhances the divergence effect of light and expands the lighting range by arranging a convex lens in the light-filling hole of the slide rail. When not in use, the light source hole can be closed by a dust cover connected by a rubber strip to prevent dust from entering and affecting the light-guiding efficiency. The design of the inspection cover facilitates the maintenance of the light-guiding strip inside the light-guiding chamber, and also plays a certain dust-proof role.

[0016] 3. The utility model sets a cleaning mechanism at the bottom of the slider, including a cleaning plate and bristles. As the slider moves on the slide rail, the bristles can automatically clean the dust and impurities in the slide groove, reduce the dust in the slide groove, avoid the dust affecting the lighting effect, and can reduce the wear between the slider and the slide rail, which is conducive to maintaining the good operating state of the slide rail and extending the service life.

[0023] See also Figure 1-Figure 5 A guide rail for elevator maintenance, comprising a slide rail 1 and a slider 2, a slide groove 101 is arranged on the side of the slide rail 1, the slider 2 is inserted into the slide groove 101 and is slidably connected with the slide rail 1, a fill light mechanism 3 is arranged in the slide rail 1, and a cleaning mechanism 4 is arranged at the bottom of the slider 2;

[0024] The fill light mechanism 3 includes an LED flashlight 302 and a light guide strip 301. A light guide chamber 105 is provided on the side of the slide rail 1 away from the slide groove 101. A light source hole 102 is provided on the front end face of the light guide chamber 105. A fill light hole 103 is provided on the side of the light guide chamber 105 close to the slide groove 101. One end of the light guide strip 301 is fixedly installed in the light source hole 102. The end of the light guide strip 301 away from the light source converges at the light source hole 102 and is fixedly installed in the light source hole 102. The LED flashlight 302 is detachably installed in the light source hole 102.

[0025] Furthermore, the fill-in light holes 103 are equidistant longitudinally on the inner end surface of the slide slot 101 , and the angle between the fill-in light holes 103 and the horizontal plane is sixty degrees.

[0026] The light from the LED flashlight 302 is diffused to each fill-light hole 103 through the light guide strip 301, and illuminated obliquely downward to fill-light the guide rails around the fill-light hole 103. The oblique downward structure can fully enhance the fill-light effect on the inner end faces of the slider 2 and the slide groove 101, and can prevent the light source from directly shining into the eyes of the maintenance personnel, thereby improving the accuracy of maintenance and preventing dust from falling into the fill-light hole 103.

[0027] Furthermore, a convex lens 107 is disposed at the end of the fill light hole 103 close to the slide groove 101 .

[0028] The convex lens 107 further improves the divergence effect of the light, thereby increasing the fill light range and reducing the lighting blind spots.

[0029] Furthermore, a dust cover 104 connected by a rubber strip is provided on the outer end surface of the slide rail 1 near the light source hole 102 .

[0030] The light source hole 102 where the LED flashlight 302 is not installed is blocked by the dust cover 104 to prevent dust from falling into the light source hole 102 and affecting the light guiding effect.

[0031] Furthermore, an inspection cover 106 fixedly connected by bolts is provided at the end of the slide rail 1 away from the slide slot 101 .

[0032] The inspection cover 106 facilitates the inspection of the light guide strip 301 in the light guide chamber 105 , thereby improving the convenience of equipment inspection.

[0033] Furthermore, an outer end surface of the LED flashlight 302 is provided with an external thread, and the LED flashlight 302 is inserted into the light source hole 102 and is threadedly connected to the slide rail 1 .

[0034] The threaded connection structure allows the LED light source to be firmly fixed in the light source hole 102, preventing the light source from shaking and affecting detection. At the same time, it prevents the light source from falling and causing safety hazards. It also facilitates disassembly and installation, allowing maintenance personnel to carry it to each light source hole 102 for installation.

[0035] Furthermore, the cleaning mechanism 4 includes a cleaning plate 401 and bristles 402 . The bristles 402 are located on the side of the cleaning plate 401 close to the slide groove 101 . The cleaning plate 401 is fixedly mounted on the bottom of the slide block 2 by bolts.

[0036] During the sliding process of the slider 2 , the bristles 402 can be driven to slide, thereby cleaning the inside of the slide groove 101 , reducing dust in the slide groove 101 , preventing dust from affecting the lighting effect, and reducing the wear between the slider 2 and the slide rail 1 .

[0037] When inspecting the slide rail 1, the elevator is turned off, the person enters the elevator shaft, the LED flashlight 302 is inserted into the light source hole 102 near the inspection area and screwed in to fix it, the LED flashlight 302 is started, and the light emitted by the LED flashlight 302 is emitted to each fill-in light hole 103 through the light guide bar 301, and is tilted downward to fill-in light for the guide rail around the fill-in light hole 103. The maintenance personnel inspect the wear condition of the slide rail 1 with the help of lighting. When changing the inspection area, the LED flashlight 302 is removed and inserted into the new inspection area to repeat the above operation, and the status of the cleaning plate 401 and the brush 402 are checked regularly. If there is severe wear or blockage, they should be replaced or cleaned in time.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
