Door- vane-free door-ball-free electromagnetic linkage type landing door device

Abstract

The invention relates to an elevator landing door control device, in particular to a door-vane-free door-ball-free electromagnetic linkage type landing door device. The door-vane-free door-ball-free electromagnetic linkage type landing door device comprises a landing door return drive device mounted on an upper door frame of a landing door, and a landing door connecting device for connecting the landing door return drive device to the landing door, wherein a driven magnetic plate which corresponds to a drive magnetic plate is arranged on the landing door connecting device; a latch hook is further arranged on the landing door connecting device; the rear end of the latch hook is mounted on the landing door connecting device through a rotary shaft; the front end of the latch hook is a hook-shaped free end; a stopper which is matched with the hook-shaped free end is arranged on the upper door frame of the landing door; the latch hook rotates around a rotary shaft to ascend and descend to realize separating and locking of the stopper; and a safety contact point is arranged on a position, on an ascending path of the latch hook, on the upper door frame of the landing door. The door-vane-free door-ball-free electromagnetic linkage type landing door device cancels hard contact between a door vane and a door ball, and is additionally equipped with an electromagnetic drive part which is in soft contact with a car door, and a user re-designs and re-regulates the safety of the landing door device as well as a door lock and safety contact of the door lock in a brand-new way according to Elevator Related Inspection Rules of Special equipment, so that the landing door device is ensured to meet or to be higher than the requirements of the inspection rules.

Description

technical field [0001] The invention relates to an elevator landing door control device, in particular to an electromagnetic linkage type landing door device without door knife and goal ball. Background technique [0002] Currently on the market, the vertical lifting box-type elevator, the door opening device is driven by a motor installed on the top of the car to open and close the car door; Coordinated croquet, by using the door knife to act on the hall door croquet to make the hall door open and close, so as to achieve the purpose of synchronous opening and closing. [0003] However, due to the small matching gap between the door knife and the door ball, due to stress release, wear, and uneven distribution of loads during elevator operation, the coordination of the door knife and the door ball often deviates, resulting in a gap between the door knife and the door. The linkage failure of the ball occurs frequently, resulting in the asynchronous opening and closing of the ...

Problems solved by technology

[0003] However, due to the small matching gap between the door knife and the door ball, due to stress release, wear, and uneven distribution of loads during elevator operation, the coordination of the door knife and the door ball often deviates, resulting in a gap between the door knife and the door. The linkage failure of the ball occurs frequently, resulting in the asynchronous opening and closing of the car door and the hall door, which often causes people to be trapped when the car door is opened but the hall door is not opened, or the hall door is accidentally opened when the car is still running. Open and the entrance of the elevator shaft is exposed, etc.

At the same time, in order to prevent the hall door from being opened artificially or accidentally, when the car reaches the position of the hall door during the operation of the elevator, the hall door is locked by a lock hook, and the lock hook cooperates with the door knife and the gate ball. And there is also a safety contact to ensure that when the car stops at the hall door, the driving circuit of the elevator car is disconnected, and the safety is guaranteed from the electrical circuit. However, due to the unstable cooperation between the door knife and the gate ball, the landing door The lock hook setting also has corresponding problems
