Elevator door lock device of vertical sliding door

Abstract

The invention relates to an elevator door lock device of a vertical sliding door. A fixed base is fixed on a stand column of the door and is provided with a lock base and a connecting rod; the lock base is internally provided with a spring and a lock latch; a bracket with a switch contact plate is fixed on the lock latch; a door ball is arranged at the upper end of a reverse L-shaped connecting rod; a bearing is arranged in the middle of the connecting rod and is sleeved on a fixed shaft; the lower end is connected with the lock latch through a lock connecting rod; a door plate is provided with a bracket with an electric switch, a locked clamp and an emergency unlocking device; the electric switch and the switch contact plate are access to a circuit; when a shaft door is closed, the distance between the locked clamp and the lock latch is not less than 7mm, and the switch is in lap joint with the contact plate; the outer force enables the connecting rod to rotate around a fixed shaft; the lock latch is disengaged from the locked clamp; and the switch is separated from the touch plate. The invention has the advantages that the door lock device beside the hall door is convenient for installation, use and maintenance; the movement is reliable, the connecting rod rotates under the gravity of the door ball during failure of the spring and the door lock device is locked; and mechanical and electric leakage is ensured to prevent false operation reliably.

Description

technical field [0001] The invention relates to an elevator locking device, in particular to a vertical sliding door elevator door lock device, which is convenient for locking the landing door after the car door and the landing door of the elevator are closed, so as to ensure the safe operation of the elevator. Background technique [0002] At present, the landing doors of elevators are mostly horizontal sliding doors, and when the width of the hoistway is limited and a wide entrance and exit are required, vertical sliding doors can be considered. According to the regulations in 7.7 of GB 7588-2003 "Safety Regulations for Elevator Manufacturing and Installation" (hereinafter referred to as regulations) implemented on 2004-01-01, landing doors need to be checked for locking and closing, that is, the "Type Test of Elevator Door Lock Devices" Certificate of Conformity" and "Type Test Report". In the past, the vertical sliding door locks at home and abroad were designed by elec...
