Problems solved by technology
The upward-turning escape door and the downward-turning ramp include the upward-turning escape door and the downward-turning escape ramp. There are steel materials, heavy weight, complex structure, large space occupation, and complicated opening and recycling operations. Only trained locomotive drivers are allowed to do it. The operation is open, and it takes a long time to open
The down-turning escape door includes the down-turning escape door and the escape ramp. The material is steel, which is heavy. There is no observation window in the closed state, which seriously affects the vision of the locomotive driver.

Embodiment Construction
[0025] See figure 1 , 2 , 3, 4, 5, 6, 7, 8 and 9, a turn-down escape device for rail vehicles, which is used in subway trains to operate by drivers or passengers in emergency situations, so that passengers can escape from the passenger compartment to the subway rail surface An escape system includes a sealing frame 1, a door leaf 2, a door lock device 5, a recovery device 6, a four-section folding pedal 7 and a movable load beam 8 forming an escape ramp, and the main structure is made of aluminum alloy. The sealing frame 1 is fixed on the vehicle body, and the sealing frame 1 and the door leaf 2 are connected through a hinge shaft 10 in a hinged manner at the bottom. There are two movable load beams 8, which are respectively arranged on the left and right sides of the four-section folding pedal 7. One end of the movable load beam 8 is hinged on the inner side of the upper end of the door leaf 2, and the other end is free. The four-section folding pedal 7 can be folded into ...

The invention relates to a turn-down type escaping device of a railway vehicle. The turn-down type escaping device comprises a sealing frame, a door page, a door locking device, a recycling device, a four-section folding pedal and a movable bearing beam, wherein the door page and the sealing frame are connected through a hinging mechanism; one end of the movable bearing beam is hinged to the upper end part of the door page; the section at the terminal end of the four-section folding pedal is fixed on the lower part of the inner side of the door page; the section at the head end is fixed on one side of the free end of the movable bearing beam; the movable bearing beam drives the four-section folding pedal to be folded and unfolded in a W form; a viewing window is formed in the upper part of the door page; the folded four-section folding pedal is located below the viewing window. The turn-down type escaping device occupies a smaller space, has a greater passing width, is light in weight and simple in structure, can be opened and closed through one-step operation, shortens the opening time of an escaping system and increases escaping chances for passengers.
Description
technical field [0001] The invention relates to a flip-down escape device for rail vehicles. Background technique [0002] At present, the escape systems on the market are divided into up-turning escape doors, down-turning ramps, and down-turning escape doors. The upward-turning escape door and the downward-turning ramp include the upward-turning escape door and the downward-turning escape ramp. There are steel materials, heavy weight, complex structure, large space occupation, and complicated opening and recycling operations. Only trained locomotive drivers are allowed to do it. The operation is turned on, and it takes a long time to turn on. The downward-turning escape door includes the downward-turning escape door and the escape ramp. The material is steel, and it is heavy. There is no observation window in the closed state, which seriously affects the vision of the locomotive driver. In order to meet the requirements of lighter weight, smaller space occupation, simpler...
