The operation of the elevator fall prevention apparatus of the present invention configured as described above will be described.

In the state where the elevator wire is fastened to the fastening part 141 of the pull bar 142, the wire pulls the pull bar 142 upward by the load of the lift, and the pull rod 143 having the stopper formed at both ends thereof is The lifting frame 130 is pulled upward.

In this state, as shown in FIGS. 5 and 6, the drive shaft 144 rotates about the hinge 146 to move the breaker 153 linked to the end of the drive shaft 144 downward to move the breaker. 153 is not in contact with the guide rail 120 and the pressing roller 152.

In this state, the elevator is in a state capable of freely lifting along the guide rail 120.

If the wire fastened to the fastening portion 141 of the elevator is broken, the pull bar 142 is pulled by the load of the pull bar 142 and the elastic restoring force of the spring 145 pulling the drive shaft 144. The drive shaft 144 is slide-moved downward along the drive bar, the drive shaft 144 is linked to both ends of the pull bar 142 is rotated about the hinge 146 to link the breaker linked to the drive shaft 144 end Lift (153).

The breaker 153 is formed in a triangular shape as shown in FIG. 7, wherein an upper side width of the breaker 153 is narrow, and a lower side width is wide, and one side of the breaker 153 facing the guide rail 120 is a breaker 153. It is formed in parallel with the surface of the vertical, the other side of the breaker 153 toward the pressing roller 152 is formed as an inclined slope.

Therefore, when the wire is broken and the drive shaft 144 lifts the breaker 153, the breaker 153 is raised and the inclined surface of the breaker 153 is in contact with the pressing roller 152, and at the same time the guide rail 120 The vertical surface of the facing breaker 153 is in contact with the guide rail 120.

As described above, the moment when the inclined surface of the breaker 153 is in contact with the pressing roller 152 and the vertical surface opposite to the inclined surface of the breaker 153 is in contact with the guide rail 120, between the vertical surface of the breaker 153 and the outer surface of the guide rail 120. The breaker 153 is brought into close contact with the guide rail 120 by the strong frictional force generated by the roller, and the pressing roller 152 descends the inclined surface of the breaker 153 by the load of the elevator while lowering the breaker 153 with the guide rail ( By pressing 120, the fall of the elevator is prevented by the strong friction force between the breaker 153 and the guide rail 120.

That is, the elevator fall prevention device of the present invention as the breaker 153 is strongly pressed against the guide rail 120 as preventing the fall of the elevator by the friction force between the vertical surface of the breaker 153 and the guide rail 120. Breakers 153 and guide rails 120 are formed by forming irregularities of various shapes on the surface of 120, and forming non-slip material layers such as silicon, urethane, and rubber on a vertical surface of the breaker 153 contacting the guide rails 120. By increasing the friction force between the) can more effectively prevent the elevator fall.

In addition, when the breaker 153 is pressed against the guide rail 120 with a strong force, the braking force may drop sharply as the guide rail 120 is bent and the breaker 153 compresses the guide rail 120. To solve the problem, as shown in FIGS. 1 and 3, one side of the breaker 153 is strongly pressed against the guide rail 120 by fastening the support 148 having a shape 'b' to the cover 147. The support 148, whose end is fastened and fixed to the cover 147, supports the guide rail 120 so that the guide rail 120 is bent to prevent the friction force between the breaker 153 and the guide rail 120 from dropping sharply. It is preferable to construct.

The breaker 153 rises due to the break of the wire, and when the breaker 153 is in contact with the guide rail 120, the elevator is suddenly braked and a big shock is transmitted to the person who is in the lift, thereby injuring the occupant. It is desirable to provide a shock absorber that can cushion the shock when the elevator suddenly falls to prevent the shock and protect the occupant.

As shown in Figures 1 and 3, the frame 110 of the elevator is fastened through the buffer rod 149 and the buffer spring 150 to the lifting frame 130, the elevator fall prevention device is installed.
