8, 4 groups of buffer mechanisms are radially arranged in the middle of the buffer frame 1 at equal intervals, and the included angle between two adjacent groups of buffer mechanisms is 90 degrees. A limiting block 10 is arranged below the buffer mechanism, and the limiting block 10 is used for limiting the damping spring 2 and preventing the damping spring 2 from moving upwards; every buffer gear of group has connecting block 9, pin 7, spring 5, connecting plate 4 and fixed plate 6, and connecting block 9 is fixed to be set up in buffer frame 1 middle part, wears to adorn pin 7 on the connecting

block

9, and 5 one ends of spring are connected with pin 7, and the 5 other ends of spring are connected with connecting plate 4, and connecting

plate

4 and 6 bolted connection of fixed plate, fixed plate 6 are fixed to be set up on the elevartor shaft wall. When the shock absorption frame is installed, firstly, the shock absorption spring 2 is welded on the base 3, then, the base 3 is fixed on the ground, and finally, the hemispherical bottom of the buffer frame 1 is placed in the shock absorption spring 2, and the shock absorption spring 2 has certain connection strength because the shock absorption spring 2 at the bottom is a main buffer element; one end of the spring 5 is connected with the connecting block 9, and the other end is connected with the connecting plate 4, and after the spring, the connecting frame and the connector are arranged on a horizontal line.

Further, the base 3 has a bottom plate 301, a hollow cylindrical connecting portion 302 is fixedly disposed on the bottom plate 301, and the lower portion of the damping spring 2 extends into the inner cavity of the connecting portion 302 and is fixedly connected with the connecting portion 302.
