Embodiment Construction
[0030] see Figure 1 to Figure 8 , the emergency front door device of an urban rail vehicle according to an embodiment of the present invention, comprising a door frame 2 connected to the car body 1, a door leaf 3, a door leaf booster mechanism 4, a first air spring 5, and one end of the first air spring 5 is connected to the door frame 2 connection, the other end is connected with door leaf 3.
[0031] A rubber pad is provided between the door leaf 3 and the door frame 2, and the door leaf 3 top is provided with a hinge, and the hinge cooperates with the hinge seat on the door frame 2. The door frame 2 is fastened with the car body 1 by bolts around it. A hinge shaft is arranged between the hinge and the hinge seat. The door leaf 3 can be flipped upward around the hinge axis under the action of the first air spring 5 . The first air spring 5 provides the supporting force for the door leaf to be opened.
[0032] The door leaf booster mechanism 4 is installed on the door le...

The invention discloses an emergency front door device for an urban rail vehicle. The emergency front door device comprises a door frame, a door leaf, and a door leaf force increasing mechanism, wherein the door frame is connected to a vehicle body; the door leaf is rotatably connected to the door frame and can be opened and closed with respect to the door frame; the door leaf force increasing mechanism is arranged on the door leaf and is used for increasing the resistance when the door leaf is opened and closed; a first air spring capable of providing supporting force is arranged between thedoor leaf and the door frame; one end of the first air spring is connected to the door frame; the other end of the first air spring is connected to the door leaf; the door leaf force increasing mechanism comprises a transverse pull tube and two supporting seats; the transverse pull tube is abutted against the upper part of the door frame; one ends of the two supporting seats are respectively connected to the two ends of the transverse pull tube; the other ends of the two supporting seats are connected to the door leaf; and the two supporting seats are respectively provided with transmission mechanisms capable of increasing the opening and closing resistance of the door leaf. The emergency front door device can avoid the problem of relatively large impact vibration between the door leaf andthe door frame in the door leaf opening or closing process, plays a buffering role in the door leaf opening or closing process, is convenient to operate and is safe and reliable.
Description
technical field [0001] The invention relates to the field of rail transit urban rail vehicles, in particular to a door leaf booster mechanism applied to the emergency front door of rail transit urban rail vehicles. Background technique [0002] The emergency front door is a kind of emergency equipment on urban rail vehicles. When the urban rail vehicle encounters an abnormal situation, stop the running urban rail vehicle, and then open the emergency front door. Passengers and staff in urban rail vehicles can reach the rail surface or rescue vehicles through emergency evacuation ramps. The previous emergency evacuation front door did not have a door leaf booster mechanism, and the impact vibration between the door leaf and the door frame was relatively large during the process of opening or closing. Contents of the invention [0003] Purpose of the invention: the present invention provides an emergency front door device for urban rail vehicles, which solves the problem th...
