Abstract
The utility model relates to a straightly-going elevator derailment alarm and protection device which comprises a sliding guide shoe or a rolling guide shoe and a guide rail. The guide rail is T-shaped, the sliding guide shoe or the rolling guide shoe is matched with two side planes and the top face of the guide rail respectively. The straightly-going elevator derailment alarm and protection device further comprises disconnection switches, wherein the disconnection switches are arranged on the sliding guide shoe or the rolling guide shoe corresponding to the two sides of the guide rail respectively and connected with a main control circuit through connecting lead wires. Each disconnection switch is composed of a permanent magnet and a magnetically controlled switch, wherein the permanent magnet is arranged on the sliding guide shoe or the rolling guide shoe located on one side of the guide rail, and the magnetically controlled switch arranged on the sliding guide shoe or the rolling guide shoe located on the other side of the guide rail and connected with the main control circuit through a connecting lead wire. By means of the technical scheme, when the guide shoe or the rolling guide shoe breaks away from the guide rail, the disconnection switches located on the guide shoe send a brake speed reducing instruction and a brake stop instruction to the main control circuit, and accordingly the purpose of safe operation of a straightly-going elevator is achieved.
