[0030] Preferably, the active driving structure 23 includes: a grinding motor 231, a first gear 232, a second gear 233 and a driving shaft 234.

[0032] Magnets (not shown) are installed on the first seat body 11 and the second seat body 12. The magnets enable the active grinding wheel 21 on the first seat body 11 and the grinding wheel on the second seat body 12 to position the active grinding wheel 21 and the driven grinding wheel 22 before positioning the detachable connecting mechanism, thereby facilitating the subsequent positioning and installation of the first sliding seat 132, the second sliding seat 133, the first seat body 11 and the second seat body 12.

[0033] In the present application, firstly, in order to adapt to the elevator guide rails 3 of different widths, a mounting seat is designed to include a first seat body 11 and a second seat body 12 that can be close to or far away from each other, so that the active grinding wheel 21 and the driven grinding wheel 22 can fully contact with the elevator guide rail 3, and at the same time, a driven driving structure 24 is designed, and the driving belt 243 in the driven driving structure 24 can be replaced according to the relative position change of the first seat body 11 and the second seat body 12, so that the grinding motor 231 drives the active grinding wheel 21 and the driven grinding wheel 22 to rotate; then, in order to realize the positioning of the first seat body 11 and the second seat body 12, a connecting rod 1341 and a connecting nut 1342 are designed to cooperate with each other, so that the active grinding wheel 21 and the driven grinding wheel 22 can be fully contacted with the elevator guide rail 3. The grinding wheels 22 are all in close contact with the elevator guide rails 3; then, since the elevator car may have a certain position change relative to the elevator guide rails 3 during the installation of the elevator, there will be a position error change between the base 131 on the elevator car and the elevator guide rails 3, so the first sliding seat 132 and the second sliding seat 133 are designed to be able to move on the base 131 to adapt to the position error change between the base 131 on the elevator car and the elevator guide rails 3, so that the active grinding wheel 21 and the driven grinding wheel 22 can move to a position close to the elevator guide rails 3; then, in order to locate the positions of the first sliding seat 132 and the second sliding seat 133, a positioning mechanism is designed; finally, in order to facilitate adjustment, the connecting rod 1341 is adjusted into place to make the positioning The positioning mechanism positions the first sliding seat 132 and the second sliding seat 133, and at the same time, a shorter cylindrical section 42 is designed to press down the first positioning arm 1351, because it is convenient to adjust the connecting rod 1341 to a position away from the first positioning arm 1351, so as to facilitate the movement of the first sliding seat 132 and the second sliding seat 133. When the cylindrical section 42 presses down the first positioning arm 1351, since there are guide rods 52 and guide cylinders 51 between the first positioning arm 1351 and the second positioning arm 1353, the guide rods 52 and guide cylinders 51 do not hinder the movement of the first seat body 11 relative to the first seat body 11, and can also realize that when the first positioning arm 1351 is pressed down, the second positioning arm 1353 is driven to descend to the meshing position with the rack 1355, that is, The purpose is to realize positioning of the first sliding seat 132 and the second sliding seat 133, and to position them simultaneously (if a shorter cylindrical section 42 is not designed to contact and press down the first positioning arm 1351, a very long connecting rod 1341 needs to be designed to press down the first positioning arm 1351 and the second positioning arm 1353 simultaneously, which will reduce the length of the threaded section 44, resulting in the inability to adapt to the elevator guide rail 3 with a large width change. This design of a shorter cylindrical section 42 can adapt to the elevator guide rail 3 with a large width change, and after the first seat body 11 and the second seat body 12 move relative to each other, the first positioning arm 1351 can still be pressed down, and the first positioning arm 1351 drives the second positioning arm 1353 to descend through the guide rod 52 and the guide cylinder 51).

[0034] A third gear 251 is fixed on the driven shaft 244, and the third gear 251 is fixed on a rotatable rotating shaft 252. The rotating shaft 252 is rotatably mounted on the second base body 12, and a first bevel gear 253 is fixed on the rotating shaft 252. A second bevel gear 254 is meshed with the first bevel gear 253, and the second bevel gear 254 is fixed to a first semi-shaft 255. The first semi-shaft 255 is rotatably mounted on the second base body 12, and a width grinding wheel 256 is fixedly mounted on the first semi-shaft 255. An insertion hole is provided at the axis center line of the width grinding wheel 256, and the insertion hole is for the second semi-shaft 257 to be inserted. The second semi-shaft 257 is rotatably mounted on the first base body 11, and the second semi-shaft 257 can move in the axis center line direction relative to the width grinding wheel 256 to adapt to the width change of the elevator guide rail 3. The width grinding wheel 256 grinds the elevator guide rail 3 in the width direction, thereby realizing the grinding and rust removal of the three sides of the elevator guide rail 3 to achieve the cleaning effect.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
