Description

High-altitude slow-descending equipment

Technical field

The present invention relates to a kind of high-altitude slow-descending equipment, belong to the height rescue apparatus field.

Background technology

Height rescue equipment mainly uses when high-rise field rescue or work high above the ground personnel fall and uses.When running into major accident such as fire or earthquake when high-rise, personnel have little time to withdraw in the building, or because of corridor, elevator are blocked, are ruined, when personnel can't withdraw in the building, use salvage device to flee from the scene of the accident from window.

Existing high-rise building rescue aid has only the employed high-altitude of fire department aerial ladder, nylon rope and inflatable packer, their maximum drawback is subjected to limitation in height exactly, can only succour the victim of height about floor rooms 10 at most, surpass this and highly just be difficult to succour.At present, in actual life, also do not see the high-altitude self-help apparatus and asked the city.

Summary of the invention

Purpose of the present invention is in order to provide a kind of high-rise building resident family the high-altitude slow-descending equipment of saving oneself and using in danger.At first, with one sufficient length is arranged, can be installed in the roof suitable position from the steel wire rope elevator device that roof arrives ground, the firing switch line of steel wire elevator case be drawn in the man of resident family that delivers to pairing each floor by roof, and switch handle is set on each household window limit.When running into emergency situation, resident family just can open steel wire elevator case switch, and the steel wire rope of roof will fall to ground by roof immediately.The survivor can open the window, and steel wire rope is pulled indoor, descending lifeline is dressed and is hung on the steel wire rope indoor, places outdoor again from window.At this moment, survivor's both hands are held the handle on the descending lifeline, clutch brake lever, just can drop on the ground stably from the speed of window with 1 meter of per second.Live in the people in the floor rooms 20, only need 1 fen clock time ground of just can arriving safe and sound.

In order to achieve the above object, the present invention realizes by following technological means.
