It can automatically brake the elevator when the elevator is not powered on. The output end of the electromagnetic device 71 passes through the mounting frame 6 and extends to be fixedly sleeved with a linkage sleeve plate 73. A group of guide rods 74 are movably sleeved on the linkage sleeve plate 73 to facilitate guiding the linkage sleeve plate 73 so that its vertical movement is more stable. The upper end of the guide rod 74 is connected to the mounting frame The lower end of the guide rod 74 is fixedly connected with a support plate 75, and the support plate 75 is fixedly connected to the bottom surface of the mounting frame 6. Linking rods 76 are hingedly provided on both sides of the linkage sleeve 73, and a clamping assembly 77 is hingedly provided at one end of the linkage rod 76, which can drive the clamping assembly 77 to move and close to the outer wall of the brake wheel 4 at the same time. The inner wall of the brake frame 72 is provided with an avoidance groove 78, and the clamping assembly 77 is located in the avoidance groove 78, which is convenient for avoiding the clamping assembly 77. Slide grooves 79 are provided on both sides of the inner wall of the avoidance groove 78, and the slide grooves 79 are symmetrically arranged.

[0031] like Figure 3 and Figure 4 As shown, the clamping assembly 77 includes a brake clamp 771, and sliders 772 are fixedly provided on both sides of the outer wall of the brake clamp 771. The sliders 772 are slidably connected to the slide grooves 79, which are convenient for guiding the brake clamp 771, making it move more stably and tightly adhere to the outer wall of the brake wheel 4. The inner ring surface of the brake clamp 771 is fixedly connected with a fixing block 773, and the inner ring surface of the fixing block 773 is provided with a clamping groove 774, and the clamping groove 774 is a "convex" shape structure.

The linkage sleeve 73 drives the brake clamp 771 to move upward in the avoidance groove 78 through the linkage rod 76. The brake clamp 771 drives the slider 772 to slide upward in the slide groove 79. At the same time, the brake clamp 771 drives the mounting block 776 to move at the same time through the fixing block 773, and the mounting block 776 drives the brake block 777 to move at the same time, so that the brake block 777 moves upward and close to the outer wall of the brake wheel 4, and applies a stable pressure to the brake wheel 4, thereby producing a stable braking on the brake wheel 4, achieving the same braking effect, and ensuring the safety of the elevator.

[0037] When replacing the brake block 777, first pull out the block 775 from the slot 774, install the new brake block 777 on the mounting block 776, and reinsert the block 775 at the bottom of the replaced brake block 777 into the slot 774, so as to quickly replace it and improve the replacement efficiency.
