Embodiment Construction

[0062] 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.

[0063] Such as figure 1 , figure 2 and image 3 As shown, the emergency escape and evacuation ramp device of the urban rail transit vehicle of the present invention includes a ramp recovery mechanism 1, an escape door recovery mechanism 2, a connecting rod mechanism 3, a pedal mechanism 4, an adaptive support leg 5, and a retractable rail 6 and recovery rope 7,

[0064] The ramp recovery mechanism 1 and the escape door recovery mechanism 2 are symmetrically installed on the front end or rear end of the urban rail transit vehicle body, and the ramp recovery mechanism 1 is used to realize ramp folding. Controlling the rotation of the ratchet wrench can realize the folding of the emergency es...

Abstract

The invention discloses an emergency escape and evacuation ramp device for urban rail transit vehicles, is suitable for escape of space limiting, and especially for front door or back door escape of the urban rail transit vehicles. A scissor fork linkage mechanism is used as a guiding motion device and is cooperates with a pedal mechanism to do contracting and folding motion for realizing rapid winding and rewinding of a ramp. An adaptive supporting leg mechanism is arranged and is applied to the supporting surfaces of different heights. A retractable rail is arranged and applied to the complex rail surface environment such as straight ways and curved ways by using a retractable pulling rod structure. A ramp rewinding mechanism and an escape door rewinding mechanism are arranged, and operation of single person ramp rewinding can be achieved. A damper and a buffering device are additionally arranged, the impact of the gravity impact and pedal mechanism rewinding on the ramp rewinding mechanism and the escape door rewinding mechanism is eliminated. A pedal lock is additionally arranged, the ramp can be effectively locked, safety and reliability are achieved, the time of winding and rewinding of the emergency escape and evacuation ramp is short, operation is convenient, and the good application prospect is achieved.

Description

technical field [0001] The invention relates to an emergency escape and evacuation ramp device for urban rail transit vehicles, belonging to the technical field of rail transit vehicle components. Background technique [0002] With the rapid development of urban rail transit, the demand for urban rail transit vehicles is also increasing. At present, emergency escape and evacuation ramp devices are installed on urban rail transit vehicles. The emergency escape and evacuation ramp devices are used to facilitate the rapid escape of passengers in the case of emergency failures, especially in narrow underground passages. [0003] The existing emergency escape evacuation ramp device has the following deficiencies, [0004] (1) It is necessary to install a recovery belt hoisting structure on the top of the car body, the installation interface is complicated, and there is a need for reinforcement of the roof; [0005] (2) The structure of the folding pedal and the recovery belt is...
