Description

Ramp type emergency evacuation door for subway locomotive

technical field

The invention relates to a locomotive emergency evacuation door.

Background technique

All subway locomotives are equipped with emergency evacuation doors. The emergency evacuation doors are located at the front center or one side of the driver's cab, and the door body matches the shape of the driver's cab. Its function is to deploy in an emergency, so that passengers can be safely transferred from both ends of the train, so as to avoid or reduce the casualties of passengers. For the ramp-type emergency evacuation door, an evacuation ramp is formed behind the door body. A subway locomotive escape door device disclosed in the invention patent specification of China Authorized Notice No. CN10048743C (Patent No. 200610076658.6) is a ramp-type emergency evacuation door. The above-mentioned escape door device includes a door body and a door body retractable mechanism. The door body is hinged in the middle. After being unfolded, it forms a plate shape, and after being folded, it forms an inner and outer folding door body. The bottom end of the outer layer of the door is hinged on the car body. , The ramp formed by the door body is relatively gentle, and the door body retractable mechanism is a cable-type retractable mechanism. Because the door body forms the folding door body of inner and outer layers after being folded, glass windows are not installed on the door body of the ramp-type emergency evacuation door of the subway locomotive at present, so that the observation window in the front of the car is relatively small.

Contents of the invention

To achieve the above object, the present invention takes the following technical solutions:

The ramp-type emergency evacuation door for a subway locomotive proposed by the present invention has a door frame and a flip-out door leaf. The door leaf has a frame-shaped frame and a door leaf plate body. The plate body is divided into a light-transmitting part and a sealing part, the light-transmitting part is provided with a window, and glass is installed in the window; the first-level pedal brackets are respectively fixed on the two longitudinal columns forming the frame frame, and the two first-level pedal brackets are in the One end of the light-transmitting part is hinged with a second-level pedal bracket that can be turned outward. A first-level fixed pedal and a first-level folding pedal are fixed between the two first-level pedal brackets. Between the second-level pedal brackets The second level of folding pedals and the second level of fixed pedals are hinged, the second level of folding pedals and the first level of folding pedals are hinged, and the opposite surfaces of the two first level pedal brackets are respectively fixed with first level pedal shelves. A second-level pedal shelf is respectively fixed on the opposite surfaces of the two second-level pedal brackets. When the door leaf is turned outwards and is in an unfolded state, the first-level folding pedal rests on the two first-level pedal shelves. The two-level folding pedal rests on the two second-level pedal shelves. The first-level fixed pedal, the first-level folding pedal, the second-level folding pedal and the second-level fixed pedal are on the same plane to form a ramp. When the door When the door is closed, the first-level folding pedal and the second-level folding pedal are clamped between the first-level fixed pedal and the second-level fixed pedal, and all the pedals are folded on the back of the door panel body sealing part; Both the first-level pedal bracket and the second-level pedal bracket are U-shaped, and the two first-level pedal brackets are hinged with four-link structure handrails. When in a folded state, the opening of the first-level pedal bracket and The openings of the second-stage pedal brackets are combined to form a box body, and the railing handrails are stored in the box body.

The longitudinal column of the door leaf frame, the first-level pedal bracket and the first-level pedal shelf are integral aluminum profile parts.

The second-level pedal bracket and the second-level pedal shelf are integral aluminum profile parts.

The railing handrail of the four-link structure includes a first connecting rod hinged in the middle of the first-stage pedal bracket, a second connecting rod hinged at the junction of the first-stage pedal bracket and the second-stage pedal bracket, and two ends respectively The swing rod hinged with the first connecting rod and the second connecting rod, the outer surface of the first connecting rod is provided with an armrest lifting frame composed of upper and lower legs and a straight handle, and a chain passes through the armrest to lift the frame The space between the upper and lower feet of the door frame, one end is connected to the top of the door frame, and the other end is connected to the first-level pedal bracket. When the door leaf is unfolded, the chain is tightened against the upper foot of the handrail lifting frame to lift the railing handrail lift up.

The present invention has the following positive effects: 1. The present invention consists of a first-stage fixed pedal, a first-stage folding pedal, a second-stage folding pedal and a second-stage fixed pedal to construct an evacuation channel. When the door leaf is in a folded state, the first The first-level folding pedal and the second-level folding pedal are clamped between the first-level fixed pedal and the second-level fixed pedal, and all the pedals are stored on the back of the closed part of the door leaf, so the upper part of the door leaf can be set to be transparent It improves the lighting conditions of the train cab and expands the driver's field of vision ahead. 2. When the door leaf is closed, the first-level pedal bracket and the second-level pedal bracket are combined to form a box, and the railings and handrails are stored in the box, making the environment of the driver's cab clean and tidy.
