When the brake is in normal use, the electric push rod 607 drives the fixing column 608 to move and engage in the fixing hole 605 on the support frame 603, fixing the support frame 603, so that the brake frame 2 can drive the support frame 603 and the brake pad 604 on one side of it to normally press against the outer wall of the brake wheel 103, locking the brake wheel 103. When the gap between the brake pad 604 and the outer wall of the brake wheel 103 is abnormal and the brake wheel 103 cannot be well locked, the electric push rod 607 starts to control the fixing column 608 to disengage from the fixing hole 605, so that the support frame 603 can rotate, and the first cylinder 601 starts, and the first support block 602 is used to push the upper and lower ends of the brake pad 604, so that the brake pad 604 presses against the brake wheel 103, which can achieve a good emergency effect.

When canceling the fixation of the brake wheel 103, the second cylinder 613 is started to control the second support block 614 to retract, and the torsion spring rebounds to drive the auxiliary frame 609 to return to its original position.

When the driving motor 102 is started, the electromagnet 105 is started synchronously, and the push rods at both ends of the electromagnet 105 extend, driving 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 towards 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.

[0052] In this embodiment, the driving motor 102 controls the forward and reverse rotation of the traction wheel 104 to drive the steel cable thereon to move, driving the elevator car to lift and lower.

[0053] Workflow and principle of the present invention: When the elevator traction machine works, the drive motor 102 controls the forward and reverse rotation of the traction wheel 104, drives the movement of the steel cable thereon, and thus drives the lifting and lowering of the elevator car body. When the drive motor 102 starts, the electromagnetic block brake installed on the elevator traction machine starts the electromagnet 105 synchronously. The push rods at both ends of the electromagnet 105 extend, driving the brake pad 604 away from the surface of the brake wheel 103. When the drive motor 102 is turned off, the electromagnet 105 is turned off synchronously. The first spring 204 supports the rotation of the brake frame 2 towards the brake wheel 103 through its elastic force, making the brake pad 604 tightly attached to the outer wall surface of the brake wheel 103, locking and fixing the brake wheel 103 to prevent the accidental rotation of the traction wheel 104.
