Abstract

The invention discloses a landing door opening protection device with an improved structure. The landing door opening protection device comprises a landing door limit component, wherein the landing door limit component comprises a rotary swing locking block and a limit piece which is in interference fit with the rotary swing locking block in a clamping way; the movement locus plane of the rotary swing locking block is parallel with a horizontal plane or forms an acute angle with the horizontal plane; a coupler lock swing arm and a driving swing arm are arranged by extending the rotary swing locking block towards two outer sides along the rotary swing axis; the limit piece is fixedly connected with a landing door guide rail frame and is vertically downward. Compared with the prior art, the landing door opening protection device has the beneficial effects that 1, the whole structure is simple, the size is small, the mounting is convenient, the universality is strong, and the landing door opening protection device can be directly mounted on an existing landing door without a landing door protection device; 2, a non-contact structure is adopted, no friction and no noise exist, the wear rate is low, and the operation comfort of an elevator is improved; 3, the operation is convenient, the action is sensitive, the safety performance is strong, the possibility that an operator accidentally falls into a hoistway is reduced, and the personal safety of the operator is guaranteed.

Description

technical field [0001] The invention relates to a landing door opening protection device, which belongs to the technical field of elevator equipment, in particular to an elevator landing door opening protection device with an improved structure that provides safety guarantee for special operators. Background technique [0002] At present, during the maintenance and use of common elevator products, maintenance personnel or elevator management personnel usually use the triangular key that is standard in the elevator during daily use and maintenance, unscrew the triangular lock installed on the upper part of the landing door, and open the elevator landing door. Perform a series of operations such as entering the pit, observing the inner movement of the shaft, entering the car to start the elevator, and entering the car top for measurement, inspection and maintenance. [0003] The car door opening protection device of the elevator car door, its main function is to ensure that wh...
