Abstract

The invention provides an elevator door lock bypass device and a control loop thereof. The device comprises a control cabinet signal processing unit and a door lock bypass control unit, the control cabinet signal processing unit is in signal connection with door lock contacts of all landing doors of an elevator and is used for collecting information of the landing doors of the elevator, a car roofsignal processing unit is in signal connection to a door lock contact of a car door of the elevator, and used for collecting car door information and transmitting the information to the control cabinet signal processing unit, a door lock bypass unit is a third-gear rotary knob switch on a control cabinet, and is in signal connection to the control cabinet signal processing unit, the door lock bypass unit comprises an elevator safety loop, a door lock loop and an emergent electric loop which are connected to the control cabinet signal processing unit; through opening and closing of the contacts, the elevator running state in door lock bypass can be controlled. According to the elevator door lock bypass device and the control loop thereof, the problem that when elevator failures are recovered, the elevator suddenly runs, and elevator maintaining persons and passengers have safety shearing and extruding accidents is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment safety, and in particular relates to an elevator door lock bypass device and a control circuit thereof. Background technique [0002] Regulations on landing door and car door bypass devices have been added to the draft for comments on elevator manufacturing and safety regulations (GB7588.1-201X). The requirements clearly stipulate: (1) In order to maintain the landing door contact, car door contact and door lock contact, a bypass device should be installed on the control panel or emergency and test operation panel. (2) The device should meet the following functional requirements: a) make the normal operation control invalid; b) can bypass the landing door close contact, landing door lock contact, car door close contact and car door lock contact; c) The landing door contact and the car door contact cannot be bypassed at the same time; d) In order to allow the car to run after the car do...
