Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, an emergency evacuation ramp for urban rail vehicles comprises a foldable ramp main body 1, the both sides of the front end of the ramp main body 1 are respectively provided with a frame 2, and both sides of the ramp main body 1 are respectively provided with There is a four-bar mechanism 3 for realizing the folding or unfolding of the ramp main body 1, and the frame 2 is respectively connected with the four-bar mechanism 3 on the corresponding side through the speed-limiting damper 4, and the two ends of the speed-limiting damper 4 are connected with the machine respectively. The frame 2 and the four-bar mechanism 3 are hinged, and the speed-limiting damper 4 outputs the damping force to control the deployment speed of the ramp body 1. A speed-limiting damper is added to stabilize the ramp deployment speed. When the deployment speed e...

Abstract

The invention discloses an emergency evacuation ramp for an urban rail vehicle and a control method. The emergency evacuation ramp comprises a folding ramp main body, wherein racks are arranged on the two sides of the front end part of the ramp main body respectively; four-rod mechanisms for realizing folding or expanding of the ramp main body are arranged on the two sides of the ramp main body; the racks are connected with the four-rod mechanisms on the corresponding sides through speed-limiting dampers respectively; the expanding speed of the ramp main body is controlled by the speed-limiting dampers; the end parts of the speed-limiting dampers are hinged to the racks and the four-rod mechanisms. By additionally arranging the speed-limiting dampers for stabilizing the ramp expanding speed, damping force is produced by the dampers to control the expanding speed when the expanding speed exceeds a set value, impact damage caused to parts and impact noise are avoided, the service life is prolonged, the safety performance is improved, and good application prospect is realized.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an emergency evacuation ramp for urban rail vehicles and a control method. Background technique [0002] The emergency evacuation ramp is the equipment used by urban rail vehicles to evacuate the vehicle drivers and passengers in an emergency. It is generally installed on the head of the vehicle and located directly behind the emergency evacuation door. After the emergency evacuation door is opened, the emergency evacuation ramp is activated. The road is unfolded to form an evacuation channel for drivers and passengers. Evacuation ramps are widely used because of their high evacuation efficiency, simple operation, and short time to form evacuation channels. [0003] The traditional emergency evacuation ramp is composed of multi-level pedals, rods, handrails and locking components, etc. The multi-level pedals and rods are hinged through rotary pairs to form a multi-rod...
