High floor fire self-help escape device

Abstract

The invention belongs to the technical field of fire self-help device, and particularly relates to a high floor fire self-help escape device. The high floor fire self-help escape device comprises a shell, two air cylinders, a first rope, first rotary shafts, second ropes, a pedal, a first air bag and a handrail; the two air cylinders are arranged in the inner wall of the shell; pull rings are arranged on piston rods of the air cylinders and fixedly connected with the piston rods of the air cylinders; the first rotary shafts are mounted in the shell through the pull rings, and the first rotaryshafts are rotatably connected with the pull rings; one end of the first rope is wound in the middles of the first rotary shafts, and the other end of the first rope is fixed to a wall body; the second ropes are mounted at the lower end of the shell; the pedal is mounted below the shell through the second ropes; the first air bag is mounted at the bottom of the pedal, and the first air bag is connected with the air cylinders through pipelines; the handrail is mounted at the bottom of the shell; a first switch is arranged at the left end of the handrail; two friction wheels are further arrangedin the shell, and the friction wheels are mounted on the first rotary shaft in a left-right symmetry mode.

Description

technical field [0001] The invention belongs to the technical field of fire self-rescue devices, in particular to a high-floor fire self-rescue escape device. Background technique [0002] Fire refers to a catastrophic burning phenomenon that is out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. In a fire, people are often trapped in windows, balconies and other places, unable to escape the fire scene. Because fire engines and other life-saving devices did not arrive in time for rescue, or the fire spread too fast, they chose dangerous methods such as jumping from buildings in a panic escape. This way of escaping will bring life danger or disability, but if you wait for rescue in place, you may be choked to death by the thick smoke and poisonous gas generated by the fire. Therefore, how to use a simple escape device in a short time Carrying out self-re...

Problems solved by technology

[0004] In the above-mentioned Patent Document 1, by using the weight of the human body to step on the foot rod, the friction coefficient is adjusted by using the leverage principle, and the friction coefficient is adjusted by the eccentric rotation of the rotating shaft in different degrees, so that the rotating shaft slows down or stops rotating, so as to slow down the speed of descent. Or stop falling; this invention can achieve the purpose of escape well under normal circumstances, but when the device has not been used for a long time and some ropes are stuck due to corrosion, mud or other conditions, the device and the person are stuck in mid-air. Causes physical and psychological damage to personnel; at the same time, this invention cannot prevent personnel from being affected by smoke when escaping, and this invention has major defects
