The head of the bolt 5 is stuck on the upper end surface of the transverse plate 15 and the rod passes through the transverse plate 15, the washer 11, the horizontal plate 16 and the shock-absorbing pad 0 and is tightened with the first nut 6 and the second nut 13. The wing plate 18 is parallel to the horizontal plate 16. The wing plate 18 can provide an installation position for other structures of the elevator while also improving the strength of the upper beam 1. The vertical plate 17 A mounting groove is formed between them, and the width of the shock-absorbing pad 0 in the natural state is matched with the width gap of the mounting groove. The shock-absorbing pad 0 is arranged in the mounting groove. Since the shock-absorbing pad 0 is matched with the gap of the mounting groove, it is easy to install the shock-absorbing pad 0 in the mounting groove. When the first nut 6 and the second nut 13 are tightened, the shock-absorbing pad 0 is compressed by the lower support seat 12 and the width increases and is pressed against the mounting groove, so that the upper mounting seat is fixed more firmly. Trapezoidal grooves 19 are respectively provided at both ends of the horizontal plate 16, and the guide rails 20 of the car are located in the grooves 19. The grooves 19 can also improve the limiting effect of the accompanying cables arranged along the guide rails 20 to prevent them from shaking during the operation of the elevator.

The rest of the pulley 4 lies within the outline of the wheel cover 7. The axle 8 is inserted through the fixed plates 3, and the pulley 4 is rotatably connected to the axle 8. The axle 8 extends outward from the outer surface of the fixed plates 3 and is provided with a limiting surface. The top structure includes a limiting plate 22 provided on the outer surface of the fixed plates 3. The limiting plate 22 abuts against the limiting surface to prevent the axle 8 from rotating.
