When the drive motor 102 is started, the electromagnet 105 is started synchronously, and the push rods at both ends of the electromagnet 105 are extended to drive the brake pad 604 to leave the surface of the brake wheel 103. When the drive motor 102 is turned off, the electromagnet 105 is turned off synchronously, and the first spring 204 supports the brake frame 2 to rotate toward the brake wheel 103 through its elastic force, so that the brake pad 604 is tightly attached to the outer wall surface of the brake wheel 103.

[0030] In this example, the traction wheel 104 is controlled to rotate forward and reversely by the driving motor 102, thereby driving the steel rope thereon to move and driving the elevator car to move up and down.

[0031] The working process and principle of the present invention are as follows: when the elevator traction machine is working, the driving motor 102 controls the traction wheel 104 to rotate forward and reverse, driving the steel rope thereon to move, thereby driving the elevator car body to rise and fall. When the driving motor 102 of the elevator traction machine is started, the electromagnet 105 is started synchronously, and the push rods at both ends of the electromagnet 105 extend to drive the brake pad 604 to leave the surface of the brake wheel 103. When the driving motor 102 is turned off, the electromagnet 105 is turned off synchronously, and the first spring 204 supports the brake frame 2 to rotate in the direction of the brake wheel 103 through its elastic force, so that the brake pad 604 is tightly attached to the outer wall surface of the brake wheel 103, and the brake wheel 103 is stuck and fixed to prevent the traction wheel 104 from rotating accidentally.
