Emergency unlocking device of motor train unit door system

Abstract

The invention provides a motor train unit door system emergency unlocking device which comprises a mounting plate, a lock cylinder, an operating handle, a fixed panel connected with the mounting plate and a breakable panel in the middle of the fixed panel and further comprises a transmission shaft, a rotating cam, an electromagnet, an electromagnet telescopic rod, a lock hook and a limiting component. The lock cylinder and the operating handle are fixed at one end of the transmission shaft, and the rotating cam is mounted at the other end of the transmission shaft; the other end of the steel wire rope is fixed with a locking device opening valve; an electromagnet telescopic rod is arranged on the upper portion of the electromagnet, and the electromagnet telescopic rod and the lock hook are connected to form a rotating pair. And a limiting component is arranged on the rotating cam, is columnar and is matched with the lock hook. The electromagnet and the rotating handle are integrated together, overhaul and maintenance are convenient, the structure is compact, the occupied space is small, and random arrangement can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit vehicle door systems, and in particular relates to an emergency unlocking device for an EMU door system. Background technique [0002] The existing high-speed EMUs with a speed of 200 kilometers per hour and above use a single electric plug-in door, and its locking device is arranged on the side equipment rack. The main lock is equipped with an unlocking cylinder and a locking cylinder. In the case of air, unlock and lock the door lock by unlocking the cylinder and locking the cylinder. At the same time, the main lock is connected to the emergency unlocking device through a wire rope, and the emergency unlocking device can be used to pull the wire rope to realize unlocking under abnormal conditions. [0003] In order to ensure the operation order and safety of the EMU, an electromagnet linkage mechanism is installed in front of the internal emergency unlocking, as shown in the figure below. ...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve the problem that the existing emergency unlocking device and electromagnet linkage mechanism have complex structures and take up a large space, thereby providing an emergency unlocking device for a train door system, which has a simple structure and a small footprint, and can be used in emergency situations. Open the door to ensure rescue needs, and at the same time prevent random operation in non-emergency situations, affecting the operation order and driving safety of the EMU
