AI Technical Summary
The wear of the existing elevator guide boot lining is difficult to accurately judge, resulting in problems with elevator car shaking and noise.
A boot lining is designed, with a concave or convex wear value mark on the inner wedge, which reflects the wear condition of the guide boot through the position and shape of the wear mark, making it easier to judge the wear degree of the boot lining by taking a photo.
Through the existence of wear value marks, the maintainer can quickly judge the wear of the boot lining, replace it in time, improve the speed of maintenance, and ensure the safety of elevator operation.

Abstract
Description
Technical Field
[0001] The utility model relates to an improvement on the guide shoe and shoe lining structure of an elevator. Background Art
[0002] Elevator guide shoes are used in conjunction with elevator guide rails. During use, the shoe lining will slowly wear out.
[0003] The wear of the shoe lining depends on many factors, including frequency of use, quality and manufacturing materials. If the elevator is used frequently, the wear of the guide shoe lining may be more serious.
[0004] When the shoe lining is worn too much, a large gap will appear between the elevator guide shoe and the guide rail, causing the car to shake and make noise.
[0005] Therefore, we need to check the wear of the guide shoe lining during regular maintenance of our elevators. However, it is not easy to judge the degree of wear of the elevator guide shoe lining. Utility Model Content
[0006] In order to overcome the disadvantage that it is difficult to judge the wear condition of the shoe lining of the existing elevator guide shoe, the utility model provides an elevator guide shoe and a shoe lining.
[0007] The technical solution of the utility model to solve its technical problem is: a boot lining, the boot lining includes a U-shaped main body, the U-shaped main body includes a rear plate and a left plate and a right plate connected to the front side of the rear plate, and there is a guide rail space between the left plate and the right plate; wedge blocks are extended from the upper and lower ends of the U-shaped main body, the wedge blocks have an inner inclined surface, and are thick near the left plate and the right plate, and thin away from the left plate and the right plate, and a wear value mark is concavely or convexly provided on the inner inclined surface, and the position of the wear value mark corresponds to the wear value of the guide shoe.
[0008] The preferred design of the wear value mark is further refined. The wear value mark is a mark of a number plus a distance unit, and multiple wear value marks are arranged in a row, and the value close to the guide rail space is small, and the value far from the guide rail space is large.
[0009] A preferred embodiment of a wear value mark is that the wear value mark is convex.
[0010] For the convenience of guiding, a left wing plate is further provided on the front side of the left plate, a right wing plate is further provided on the front side of the right plate, and guiding grooves are provided at the roots of the left wing plate and the right wing plate.
[0011] The material of the boot lining is optimized. The material of the boot lining is highly wear-resistant polyurethane.
[0012] The utility model also comprises an elevator guide shoe, comprising a guide shoe seat, a side plate is arranged in the middle of the guide shoe seat, a buffer pad is arranged on the outer side of the side plate, and the shoe lining is arranged inside the side plate.
[0013] When the utility model is in use, the boot lining will be slowly worn out in daily use of the elevator. While the boot lining is worn, the wear value mark on the inner side surface can also be gradually worn out. Therefore, when we perform daily elevator maintenance, we only need to use the mobile phone camera to take a picture of the inner inclined surface of the guide shoe boot lining to see the wear condition of the boot lining, so as to judge whether the boot lining needs to be replaced.
[0014] The beneficial effect of the utility model is that the existence of the wear value mark makes it possible to display the gradual wear of the shoe lining of the elevator guide shoe during use on the shoe lining, thereby facilitating the maintainer to timely judge the wear condition of the shoe lining and replace the shoe lining as needed, thereby improving the speed of maintenance and ensuring the safety of elevator operation.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] Combined with Figures 1 to 4 , A boot lining, the boot lining includes a U-shaped main body 1, the U-shaped main body 1 includes a rear plate 2 and a left plate 3 and a right plate 4 connected to the front side of the rear plate 2, and there is a guide rail space 5 between the left plate 3 and the right plate 4; the upper and lower ends of the U-shaped main body 1 are extended with a wedge block 6, the wedge block 6 has an inner bevel 7, and is thick near the left plate 3 and the right plate 4, and thin away from the left plate 3 and the right plate 4, and a wear value mark 8 is concavely or convexly provided on the inner bevel 7, and the position of the wear value mark 8 corresponds to the wear value of the guide shoe.
[0021] The preferred design of the wear value mark 8 is further refined. The wear value mark 8 is a mark of the number 9 plus the distance unit 10, and a plurality of wear value marks 8 are arranged in a row, and the value close to the guide rail space 5 is small, and the value far from the guide rail space 5 is large.
[0022] A preferred embodiment of the wear value mark 8 is that the wear value mark 8 is convex.
[0023] For the convenience of guiding, a left wing plate 11 is further provided on the front side of the left plate 3 , and a right wing plate 12 is further provided on the front side of the right plate 4 . Guide grooves 13 are provided at the roots of the left wing plate 11 and the right wing plate 12 .
[0024] The material of the boot lining is optimized. The material of the boot lining is highly wear-resistant polyurethane.
[0025] An elevator guide shoe comprises a guide shoe seat 14, a side plate 15 is arranged in the middle of the guide shoe seat 14, a buffer pad 16 is arranged on the outer side of the side plate 15, and the above-mentioned shoe lining is arranged inside the side plate 15.
[0026] When this embodiment is in use, the guide shoe lining will be slowly worn out during daily use of the elevator. While the guide shoe lining is being worn out, the wear value mark 8 on the inner side surface may also be gradually worn out. Therefore, when we perform daily elevator maintenance, we only need to use a mobile phone camera to take a picture of the inner inclined surface 7 of the guide shoe lining to see the wear condition of the guide shoe lining, thereby determining whether the guide shoe lining needs to be replaced.
[0027] The beneficial effect of this embodiment is that the existence of the wear value mark makes it possible to display the gradual wear of the shoe lining of the elevator guide shoe during use on the shoe lining, thereby facilitating the maintainer to promptly judge the wear of the shoe lining and replace the shoe lining as needed, thereby improving the speed of maintenance and ensuring the safety of elevator operation.
