Abstract

The invention discloses an unlocking system for an elevator landing door lock. The unlocking system comprises a landing door device, a landing door panel and an electrical system; two unlocking components are installed on the panel, and the first unlocking component is used for opening a landing door in emergency; the second unlocking component plays a role in limitation to the first unlocking component; after the second unlocking component is enabled, the first unlocking component can be used for opening landing door; the second unlocking component is connected with the electrical system; after the second unlocking component is enabled, the electrical system is disconnected, and an elevator can not operate properly; and the second unlocking component needs to be reset manually, and then the elevator can be returned to run properly. According to the unlocking system, by adopting the method of limiting the first unlocking component through the second unlocking component, the possibilitythat the elevator runs properly when maintenance personnel are in a hoistway is avoided, and the safety of the maintenance personnel is ensured.

Description

technical field [0001] The invention belongs to the technical field of elevator manufacturing, and in particular relates to an elevator floor door lock unlocking system. The invention also relates to an elevator landing door. Background technique [0002] In recent years, with the development of my country's economy, the age structure of the population has changed, and the original residential buildings are not equipped with elevators, which cannot meet the access needs of the elderly, which has brought about the expansion of the elevator market. The installation of elevators often encounters situations where the depth of the pit or the height of the top floor is small. When personnel are located in the pit or on the top of the car for maintenance, the shaft cannot provide enough space for escape, which may affect the safety of maintenance personnel in the shaft. In this case, "GB / T 28621-2012 Safety Code for Manufacture and Installation of New Elevators Installed in Existi...
