Embodiment Construction

[0016] Please refer to FIG. 1 for the structure of an embodiment of the building lifesaving device of the present invention. The main components of this building lifesaving device are a rope-releasing wheel 1 and a pair of levers 3 that comprise a coiled safety rope 2 . The rotating shaft of putting rope pulley 1 is fixed on the outer wall of building by bearing 8. The fulcrum of lever 3 is a group of bearing pair 7, and its rotating shaft is fixedly connected with lever 3, and bearing is fixed on the outer wall. The two power points of the lever 3 are located on both sides of the fulcrum. The force point of lever 3 short arms is that termination 31 establishes friction block 4 and pushes against the outer periphery of putting rope pulley 1, and the force point of long arm is that termination 32 sets pulley 5 and stretches out outer wall. The free end of safety rope 2 on the rope wheel 1 passes fixed pulley 5 and is fixed with a safety hook 6.

Abstract

The invention relates to a rescue method and equipment in fire hazard that a person falls along a building by ropes, the lifesaving equipment is fixed on the outside wall of building which presets a rope wheel and level included with coiled lifesaving ropes; when encountering danger, the escape person knows position of the lifesaving equipment in advance, then runs towards the equipment and drags the insurance hook in the free end of lifesaving rope, and hangs up the safety band on his body or the temporary lifesaving band tied by the enough firm fabrics to the insurance hook, so falls along the outside wall. The invention is provided with high foreknowledge, few and stable steps, not only saving escape time but also not necessary to worry about the problem about firming the lifesaving equipment; the method applies the pressure produced by the friction block controlled by level tipping the periphery of the rope wheel, not needing man-control. There is more powerful pressure of friction block for heavier person thus everyone can safely land along with the slow releasing rope, so the method is very safe and fit for elder, women and children.

Description

Technical field [0001] The invention relates to a fire rescue method and device for descending people from a building, especially a rescue method and device for using rope descent. Background technique [0002] When a fire breaks out in a building, the elevator cannot be used, and the corridors and stairs are often filled with smoke, making it difficult for people to escape. The life-saving method is to fix the rope on the window or balcony at first, and the escape personnel climb down along the rope and land safely. However, the elderly, women and children usually do not have enough physical strength and courage to climb down the rope, so people think of using the rope release wheel coiled around the safety rope to hang the life belt on the escapee's body on the safety hook at the free end of the safety rope. The rope wheel releases the safety rope, so that the escaped person falls to the ground. Due to the effect of gravitational acceleration, the rotation of the rope-re...
