[0021] S4, before the worker arrives, the telescopic rod is extended to drive the extrusion plate to move, the extrusion plate moves in the inner side of the movable port, and the extrusion plate is tightly attached to the surface of the rotating disc of the traction machine, so that the friction plate can still normally brake the elevator after the friction force of the friction layer decreases.

[0032] 3. This invention incorporates a friction plate assembly. When the traction machine needs to decelerate, the friction plate assembly contacts the turntable on the traction machine. By ensuring the surface of the friction layer is in close contact with the surface of the traction machine turntable, the friction between the friction layer and the traction machine turntable is increased, achieving the purpose of braking. During the extrusion process, a pressure sensor detects the pressure surface of the extrusion to determine whether the pressure has weakened. When the pressure weakens, the pressure sensor transmits the signal to a handheld terminal of the worker. The user can then rotate a screw to adjust the position of the friction plate assembly as needed, performing thickness compensation to prevent the friction plate from thinning due to continuous friction, thus avoiding a decrease in friction.

[0033] 4. This invention, by installing a friction layer, a limiting ball, and an assembly groove, allows the user to move the top and bottom of the friction layer when it needs to be disassembled for maintenance, causing the limiting ball to separate from the assembly groove. When installation is required, the limiting ball on the front of the compensation layer is embedded into the assembly groove on the back wall of the friction layer, making it convenient for the user to disassemble and replace the compensation layer.

7. A method of using a friction pad for a traction machine with thickness compensation function, applicable to the friction pad for a traction machine with thickness compensation function as described in any one of claims 1-6, characterized in that, The method of using this friction pad is as follows: S1. The substrate (4) is connected to the traction machine by mounting screws (5) and installed on the traction machine to ensure the stability of the substrate (4). The substrate (4) fixes the mounting shell (1) on the front side to ensure the stability of the mounting shell (1). The mounting shell (1) limits and supports the inner support seat (7). The support frame (9) on the front side of the support seat (7) is fixed to ensure the stability of the support frame (9). S2. The support frame (9) fixes the inner threaded ring (11), the threaded ring (11) supports the inner screw (12), and the screw (12) has a handle (32) installed at the rear end. The user grips the handle (32) and rotates the screw (12). The thread on the outside of the screw (12) rotates, causing the screw (12) to move inside the threaded ring (11). The movement of the screw (12) drives the bearing seat (13) to move, the bearing seat (13) drives the connecting seat (15) to move, and the connecting seat (15) drives the friction plate assembly to move. The extension length of the friction plate assembly can be adjusted as needed. S3. When the traction machine needs to decelerate, the friction plate assembly contacts the turntable on the traction machine. The surface of the friction layer (28) is in close contact with the surface of the turntable of the traction machine, increasing the friction between the friction layer (28) and the turntable of the traction machine, thereby achieving the purpose of braking. During the extrusion process, the pressure sensor (14) detects the pressure surface of the extrusion to determine whether the pressure has weakened. When the pressure weakens, the pressure sensor (14) transmits the signal to the terminal held by the worker. The user can rotate the screw (12) as needed to adjust the position of the friction plate assembly and perform thickness compensation to prevent the friction plate from becoming thinner due to continuous friction, which would cause a decrease in friction. S4. Before the workers arrive, the telescopic rod extends and drives the extrusion plate to move. The extrusion plate moves inside the movable opening and is in close contact with the turntable surface of the traction machine. This ensures that the friction plate can still brake the elevator normally after the friction of the friction layer (28) decreases.

8. The method of using a friction plate for a traction machine with thickness compensation function according to claim 7, characterized in that, S2 also includes the following steps: S21. The mounting plate (16) inside the friction plate assembly moves, causing the guide sliders (21) on both sides to move. The guide sliders (21) move through the guide groove (10) to prevent the guide sliders (21) from deviating during the movement. S22. The guide rod (19) is fixed to the rear wall of the mounting plate (16). During the movement of the mounting plate (16), the guide rod (19) moves inside the guide tube (8) to ensure precise movement. Step S3 also includes the following steps: S31. The connecting seat (15) is inserted into the inner side of the embedded groove (18), and then the connecting screw (17) passes through the inner side of the mounting plate (16) and the connecting seat (15) to assemble the device, ensuring the tightness of the structure and avoiding the situation of falling off. S32. When the friction plate is repaired and disassembled, the user removes the assembly bolt (22) and then pushes the arc-shaped steel plate (25) laterally so that the limiting part (24) on the arc-shaped steel plate (25) comes out from the inside of the limiting groove (20) to facilitate the user's disassembly. The worker inserts the limiting part (24) on the new arc-shaped steel plate (25) into the inside of the limiting groove (20) to facilitate the user's installation of the device. S33. When the friction layer (28) needs to be disassembled and repaired, the user pulls the top and bottom of the friction layer (28) to move it, so that the limiting ball is separated from the assembly groove. When installation is required, the limiting ball on the front of the compensation layer (27) is embedded into the assembly groove on the back wall of the friction layer (28), making it convenient for the user to disassemble and replace the compensation layer (27).
