The invention discloses a device for preventing a landing door from derailing. The device comprises a sill, wherein a guide rail is arranged on the sill; the landing door capable of sliding along the guide rail to be opened and closed is arranged on the guide rail; an anti-falling barb is arranged between the lower portion of the landing door and the sill and comprises a bending plate; the upper end of the bending plate is fixedly arranged on the lower portion of the landing door; a sliding chute is formed in the lower portion of the sill; the lower portion of the bending plate is in a barb shape hooked in the sliding chute; a sliding block which is inserted into the sliding chute and can slide in the sliding chute is arranged at the lower end of the bending plate; and an opening through which the bending plate passes is formed in the sliding chute. The device has the advantages of simple structure, high safety and capability of effectively resisting over-high impact force under the condition that the landing door does not fall off.
Description
Technical field [0001] The present invention relates to an elevator landing door technical field, and particularly to an apparatus for preventing derailment landing door. Background technique [0002] Conventional elevator, the elevator landing door mounting by hanging the upper plate and the rollers of the bucket elevator floor; landing doors when open or closed, the rollers rolling on guide rails on the bottom sill, the sill rail slides along the ground simultaneously. When a passenger accidentally strikes the landing door, the landing door sill easily detached from the drop gate layer, thereby causing accidents. [0003] Further, according to regulations, the elevator door should have a certain mechanical strength, 300N without permanent deformation, but the actual use, a person might be a force of greater than 300N crash landing doors, often lead the landing door detached from the sill, resulting in a wide variety of security incidents, and even fall shaft, leading to death. ...
