Improved high-rise emergency automatic evacuation ladder
The invention relates to an invention patent which is improved in multiple aspects on the basis of an escape rope ladder, 30-50 trapped persons can be safely conveyed to the ground per minute without any power, and each step of the escape rope ladder is extended by about 10cm to a groove of a vertical fixed sliding groove mounted on a corresponding wall body of a vertical shaft wall; small pulleys corresponding to the sliding chutes in size are arranged in the sliding chutes at the two ends of the steps, so that the friction between the steps and the pulleys is reduced, and the transverse force of a hand plate pedal after a person sits on the rope ladder is stably controlled until the defect that the rope ladder is bent is overcome; personnel can go up and down more safely and stably; and the front-back size of the vertical shaft can be reduced. The sliding grooves are added, and the number of pulley pairs is reduced. And the swinging performance of the rope ladder is more stable. And the rope ladder is safer and more reliable. And the control capability is better.
本发明专利是在逃生软梯的基础上有多方面改进的发明专利，不用任何动力，每分钟可安全输送30‑50个被困人员到地面，是将逃生软梯的梯阶每头延长10厘米左右至竖井壁相应的墙体上安装垂直固定滑槽的槽内，且梯阶两头滑槽内装有与滑槽相应大小的小滑轮，既减少梯阶与滑轮的摩擦，又稳稳控制软梯上人后的手板脚蹬的横力至使软梯弯曲的缺陷；使人员上下更安全、更平稳；还能减小竖井的前后尺寸。增加了滑槽，减少了滑轮对数。更稳固了软梯的甩动性能。使软梯更安全、更可靠。更具有控制能力。
