Embodiment 1
[0057] Such as figure 1 As shown, the door slider self-inspection system includes elevator door 1, door slider 2, sill groove 3, and sonar receiver;
[0058] Such as figure 2 As shown, the door slider 2 includes a steel plate 21 and an air cushion 22;
[0059] The air cushion 22 is formed with a cavity;
[0060] The front and back sides of the steel plate 21 are respectively fixed with air cushions 22;
[0061] The upper end of the steel plate 21 of the door slider 2 is fixedly connected to the bottom of the elevator door 1;
[0062] The door slider 2 is placed in the sill groove 3, and slides in the sill groove 3 with the opening and closing of the elevator door 1;
[0063] The front and back of the steel plate 21 are parallel to the friction surface of the sill groove 3;
[0064] The surface of the air cushion 22 away from the steel plate is parallel to the friction surface of the sill groove 3;
[0065]The outer surface of the air cushion 22 away from the steel plate...
Embodiment 2
[0079] Based on the door slider self-inspection system of Embodiment 1, the upper part of the steel plate 21 of the door slider 2 is processed with pin holes, and the bottom of the elevator door is provided with pins;
[0080] The upper end of the steel plate of the door slider is fixedly connected to the bottom of the elevator door by inserting the pin into the pin hole.
Embodiment 3
[0082] Based on the door slider self-checking system of Embodiment 1, each door slider 2 has two valve cores 23;
[0083] A valve core 23 is respectively embedded in the surface of the air cushion 22 on the front and back sides of the steel plate 21 of the door slider 2 away from the steel plate.
[0084] Preferably, the valve core 23 is provided with a one-way valve. When the one-way valve is closed, the gas can only be injected into the air cushion cavity through the valve core 23, and the gas in the air cushion cavity cannot escape from the cavity.

Abstract
The invention discloses a door slider, which includes a steel plate and an air cushion; the air cushion forms a cavity; the front and back sides of the steel plate are respectively fixed with an air cushion; the surface of the air cushion far away from the steel plate is covered with an external wear-resistant surface and embedded with a valve core; The wear resistance of the outer wear-resistant layer is stronger than that of the air cushion; the inner end of the valve core is provided with a whistle and connected to the cavity of the air cushion; the outer end of the valve core is in the outer wear-resistant layer and is indented from the outer surface of the outer wear-resistant layer. 1 / 5 to 3 / 4 of the thickness of the grinding layer; when the air pressure in the air cushion cavity is greater than the set air pressure, if the outer end of the valve core is worn or deformed in the direction perpendicular to the surface of the steel plate, the valve core is connected to the air cushion cavity The internal and external air passages make the whistle emit ultrasonic waves of the set frequency band. The invention discloses a door slider self-inspection system comprising the above-mentioned door slider. The invention can automatically monitor the wear condition of the sliding block of the elevator door, and has simple structure and no disturbing noise.
Description
technical field [0001] The invention relates to elevator equipment, in particular to a door slider and a self-checking system for the door slider. Background technique [0002] The elevator doors are guided in the sill by the door sliders, which guide the doors in a straight line of movement. [0003] The commonly used door slider structure is the middle mounting plate, the mounting plate is covered with plastic rubber. The rubber has the effect of damping and silencing, and also has a certain degree of elasticity. It can squeeze through the narrow section of the sill. The friction coefficient of the rim fit is large, so the rubber surface is wrapped with wear-resistant materials (such as Teflon or nylon and other wear-resistant materials with a small friction coefficient) to reduce the friction generated when the bottom of the door moves. [0004] Due to the improper adjustment of the elevator door and other reasons, the door slider will not fall on the center of the sill ...
