Abstract

The invention provides a low-layer elevator with no bottom pit. The low-layer elevator with no bottom pit comprises an elevator well hole, an elevator cab, an elevator balance weight, a guide rail and a safety device, wherein the elevator cab, the elevator balance weight, the guide rail and the safety device are contained inside the elevator well hole. The safety device comprises an elastic buffer, a bearing plate, a pull rod and a safety plate. The bearing plate is laid on the elastic buffer at the bottom of the elevator well hole. The pull rod is connected with the bearing plate and a guard plate fixedly arranged on the guide rail. The low-layer elevator with no bottom pit achieves the safety of a maintainer entering the elevator well hole with no bottom pit and has the advantages of being convenient to install, easy to operate, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a safety device for shallow pits or low-floor elevators without pits. Background technique [0002] As we all know, in order to ensure the long-term safe and normal operation of the elevator, the elevator needs to be maintained frequently or regularly. During the repair and maintenance process, maintenance personnel will inevitably enter the elevator pit to perform operations. Therefore, the "GB7588 Elevator Manufacturing and Installation Safety Code" clearly stipulates the depth of the pit of the elevator shaft to ensure the personal safety of maintenance personnel. In order to achieve this purpose, the traditional practice in the industry is to install a buffer directly below the car and the elevator counterweight in the pit, and set a cement pier below the buffer, so that when the car compacts the buffer, There is still plenty of room for safe access at the bottom. However...
