The invention relates to a method for opening and closing an evacuation ramp of an evacuation door. The method comprises an opening step and a recycling step. When the evacuation ramp is opened, S1, the folded evacuation ramp is opened, and the evacuation ramp is stretched into a flat plate; s2, the main supporting legs are opened, the main supporting legs are approximately perpendicular to the ground, and the main supporting legs and the auxiliary supporting legs are in a herringbone shape; s3, the evacuation ramp is stretched, the front end of the evacuation ramp is gradually close to the ground, and the main supporting legs are supported on the ground; and S4, if the main supporting leg encounters an obstacle when the evacuation ramp is stretched, the main supporting leg and the auxiliary supporting leg support the ground at the same time. S5, manually pulling the auxiliary supporting legs to rotate in the direction opposite to the stretching direction of the channel; s6, when the auxiliary supporting legs coincide with the main supporting legs, the auxiliary supporting legs drive the main supporting legs to rotate in the same direction; s7, the pedal and the supporting legs are temporarily fixed; s8, the supporting legs are attached to the back face of the foremost pedal; and S9, channel recovery is completed. When an obstacle is encountered, the supporting legs are rotated, the two supporting legs are supported on the ground in a herringbone shape, and stability and safety of the evacuation ramp are guaranteed.
本发明涉及一种疏散门疏散坡道开闭方法,包括打开时的步骤和回收时的步骤。打开时:S1.打开折叠的疏散坡道,使疏散坡道伸展为平板;S2.打开主支撑脚,使主支撑脚与地面接近垂直,主、副支撑脚之间呈人字形;S3.伸展疏散坡道,疏散坡道前端逐渐接近地面,使主支撑脚支撑在地面上;S4.如伸展疏散坡道时主支撑脚遇到障碍,主支撑脚和副支撑脚同时支撑地面。回收时:S5.手动扳动副支撑脚向通道伸展相反的方向转动;S6.副支撑脚与主支撑脚重合时,副支撑脚带动主支撑脚一起向相同的方向转动;S7.将踏板与支撑脚临时固定;S8.使其支撑脚贴合在最前端踏板背面;S9.通道回收完成。本发明在遇到障碍时,使支撑脚旋转,两个支撑脚呈人字形支撑地面,保证疏散坡道的稳固、安全。
