Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0019] Such as Figure 1-Figure 4 As shown, the retractable rail of the rail transit vehicle emergency escape and evacuation ramp device of the present invention is installed under the front end of the lowermost pedal body 401 of the pedal mechanism 4 of the emergency escape and evacuation ramp to form the emergency escape and evacuation ramp. The front-end support specifically includes the first-stage rail rod 601 and the second-stage rail rod 602 that are installed in the front and rear. The structures of the first-stage rail rod 601 and the second-stage rail rod 602 are the same, only The directions are different, the first-stage rail rod 601 extends vertically and horizontally to one side o...

The invention discloses a telescopic lapping rail of a rail transportation vehicle emergency escape evacuation ramp device. The telescopic lapping rail is installed on the lower portion of the front end of a pedal body on the lowermost portion of a pedal mechanism of an emergency rescue evacuation ramp and comprises a first-level lapping rail rod and a second-level lapping rail rod which are distributed and installed at the front portion and at the rear portion, the first-level lapping rail rodand the second-level lapping rail rod are of the same structure, the first-level lapping rail rod extends to the vertical plane of one side of the front end of the pedal body on the lowermost portion, the second-level lapping rail rod extends to the vertical plane of the other side of the front end of the pedal body on the lowermost portion, and second-level telescopic rods are inserted into both the outer end of the first-level lapping rail rod and the outer end of the second-level lapping railrod. The telescopic lapping rail can stably support the pedal mechanism of theemergency rescue evacuation ramp device, when in the curved rail face, the second-level telescopic rods can be manually drawn out, supporting the rail face of a bend is achieved, it is ensured that the emergency rescue evacuation ramp is effectively supported, the safety performance is improved, the structure is smart, and the application prospect is good.
Description
technical field [0001] The invention relates to a retractable rail for an emergency escape and evacuation ramp device of a rail transit vehicle, and belongs to the technical field of rail transit vehicle components. Background technique [0002] With the rapid development of rail transit, the demand for rail transit vehicles is also increasing. At present, rail transit vehicles are equipped with emergency escape and evacuation ramp devices. The emergency escape and evacuation ramp devices are used to facilitate the rapid escape of passengers in the case of emergency failures, especially for escape and evacuation in narrow underground passages. In the existing emergency escape and evacuation ramp device, the pedal mechanism does not have the front-end support function when an emergency release is required on a curve. Especially for a curve, the angle of the ramp is unstable and there is a potential safety hazard. Contents of the invention [0003] The purpose of the invent...
