Problems solved by technology

However, the left, right and upper parts of the downward-turning evacuation door can be separated from the vehicle body. The locking mechanism described in this patent can only lock one side of the evacuation door, which will lead to evacuation after use or force. The force on the door is uneven, and even the evacuation door is not locked tightly. Once the number of locking mechanisms is increased, it will take time to unlock other locking devices when opening the evacuation door. The steps are cumbersome, which reduces the opening operation of the evacuation door. efficiency

Embodiment 1

[0037] A downward-turning emergency evacuation door for urban rail vehicles includes an evacuation door body 1, a locking mechanism 6 for controlling the opening and closing of the evacuation door, and a flip pedal structure 7 for covering the window on the evacuation door.

[0038] Described evacuation door body 1 is provided with window, and the bottom of evacuation door is connected with the installation chassis on the car body frame 5 by main link mechanism 2, and the top is provided with foldable handrail mechanism 4 and is connected with car body frame 5.

[0039] The locking mechanism 6 includes a handle assembly 601 and a safety pin assembly 602 arranged on the handle assembly 601. The handle assembly 601 is installed on the rotating shaft of the sealing frame of the vehicle body and can rotate in a small range. Described handle assembly 601 is provided with connecting rod one 607 and connecting rod two 608, and one end of connecting rod one 607 is installed on the end ...

Embodiment 2

[0047] This implementation provides a turn-down urban rail vehicle emergency evacuation door on the basis of Embodiment 1. An electromagnetic lock 611 is provided on the edge of the handle assembly 601 , and a travel switch top plate 614 is arranged on the electromagnetic lock 611 . Described car body is provided with electromagnetic lock 612, and the top of electromagnetic lock 612 is provided with lock limit switch 613, and electromagnetic lock 612 and electromagnetic lock block 611, under the situation of electrification, electromagnetic lock 612 stretches out iron core and inserts the position of electromagnetic lock block 611 In the hole, the whole door lock handle assembly 601 cannot be pulled, while the travel switch top plate 614 contacts the lock in place travel switch 613, and the signal shows that the emergency evacuation door has been locked in place. On the contrary, the iron core of the electromagnetic lock 612 is retracted when the electric signal is controlled o...

Embodiment 3

[0049] On the basis of Embodiment 1 or 2, this implementation provides a flip-down urban rail vehicle emergency evacuation door. The evacuation door is also provided with a recovery device 8, and the recovery device 8 includes a buffer mechanism 801 and a recovery mechanism 802.

[0050] The buffer mechanism 801 includes a rolling main shaft, which is provided with a damper that limits the speed of movement, passes through the suspension seat installed on the car body frame 5 and can rotate freely, and the two ends of the main shaft are respectively provided with ropes and Transmission wheel one, the two ends of the rope belt are respectively connected with the main shaft and the main body of the evacuation door.

[0051] The recovery mechanism 802 includes the second transmission wheel connected with the first transmission wheel by chain transmission. The second transmission wheel is installed on the recovery rotating shaft. A ratchet and an operating handle are installed on t...

Abstract

The invention discloses a downward turning type urban rail vehicle emergency evacuation door. The downward turning type urban rail vehicle emergency evacuation door comprises an evacuation door body, a turning pedal structure on the evacuation door body and a locking mechanism installed on an evacuation door frame and used for controlling opening and closing of the evacuation door. The turnover pedal structure is arranged on the window on the emergency door body, the turnover pedal structure can automatically turn over along with the emergency emergency door and can be embedded into the sinking table at the position of the window in a completely unfolded state, and the problem that the window is difficult to arrange on a downward-turning integrated emergency door is solved. Meanwhile, a locking mode that mechanical locking is used as a main mode and electromagnetic locking is used as an auxiliary mode is adopted, a plurality of locking devices are connected together in combination with a lock connecting rod, a transmission shaft and a transmission rod, linkage of a plurality of lock hooks is achieved, multi-point tight locking of the emergency door and a vehicle body is guaranteed, and the locking reliability is improved. And meanwhile, the problem that a plurality of locking devices on the emergency door need to be unlocked in an emergency state is solved, and the opening or locking efficiency of the emergency door is improved.

Description

technical field [0001] The invention relates to the technical field of emergency evacuation doors for urban rail vehicles, and more particularly, to a downward-turning emergency evacuation door for urban rail vehicles. Background technique [0002] According to the opening mode of the evacuation door, the common structure of the emergency evacuation door mainly includes a split structure with the door leaf turned up or sideways and the ramp turned down, such as the evacuation door disclosed in CN201820991190.1 emergency evacuation door of urban rail transit vehicle, its evacuation door Through the rollover of the upper track and the lower track, the evacuation ladder is opened and recovered by the wire rope. In the split structure where the door leaves and the ramp are separated, the structure of the evacuation door does not affect the stability or safety of the ramp. The other is a down-turning integrated structure in which the door leaf and the ramp are combined into one. ...
