Safe escape descent control device for high-rise building rescue

Abstract

A safe escape descent control device for high-rise building rescue comprises a fixing support, a first support rod, a second support rod, a buffer wheel, a safe hanging ring, a lifting rope, a liftingrope idler wheel and a safety belt. Fixing pieces are arranged at the upper and lower ends of the fixing support, and one end of the first support rod penetrates between the two fixing pieces and isfixedly connected with the two fixing pieces through fixing piece fastening screws. The first support rod and the second support rod are fixedly connected through a connecting piece, and the second support rod and the buffer wheel are connected in the mode that the safe hanging ring penetrates through a support lifting hole and a buffer wheel lifting hole. The safety belt comprises a top end safety belt body, a bottom end safety belt body, a one side end connecting belt, the other side end connecting belt and a bottom end connecting belt. One side of the top end safety belt body is fixedly connected with a lifting rope connecting belt, the lifting rope penetrates into the buffer wheel, one end of the lifting rope is bundled on a connecting ring, and the other end of the lifting rope is wound on the lifting rope idler wheel. According to the safe escape descent control device, the forms of the safety belt and a lifting hook are improved, the safe escape descent control device is suitable for disabled people with unsound limbs, the situation that in the slow descent process, trapped personnel collide with obstacles outside buildings is avoided, and thus safety performance is high.

Description

technical field [0001] The invention belongs to the field of fire escape equipment, in particular to a safety escape descent device for high-rise building rescue. Background technique [0002] With the continuous acceleration of my country's industrialization and urbanization, the above-mentioned contradictions will become increasingly prominent. According to existing data, fire accidents in high-rise buildings in some developed cities in my country have shown an accelerated upward trend. How to escape in an emergency when a fire breaks out in a high-rise building has become a social issue that people pay close attention to. At present, my country's fire emergency rescue equipment capabilities are seriously out of balance with the rapid development of high-rise buildings. In order to change the current passive situation, some manufacturers and research institutes are actively carrying out research on diversified rescue and escape technologies. In recent years, there have bee...

Problems solved by technology

There are many types of escape and descent devices on the market, but they have the following defects: (1) It is difficult to apply to the sick and disabled. Most of the seat belts are in the form of wrapping under the armpit or on the thigh, which is not suitable for people with impaired limbs. low safety factor

(2) The fixing device is a hook. The hook is fixed on the indoor wall, and the hanging rope is tied to the hook. The hanging position of the hook and the hanging rope cannot be adjusted.
