Escape device for high place

Abstract

The invention provides an escape device for a high place. The device comprises a casing, a safety belt, an escape rope, a rotating shaft and an elastic assembly, wherein a groove structure is arrangedon the inner side of the top end of the casing; the safety belt is fixed at the lower end of the casing; the rotating shaft is rotationally arranged below the groove structure and forms an accommodating part together with the groove structure; the elastic assembly provides first elastic acting force for the rotating shaft, so that the accommodating part has the size kept to allow the no-joint part of the escape rope to pass by; a first end of the escape rope penetrates through the accommodating part to be fixed in the high place; when the escape device for the high place is descended, the escape rope slides in the accommodating part; when the escape rope slides to the joint part, the escape rope gets stuck and cannot move; when first pull force is provided, the elastic assembly moves relative to the rotating shaft, the joint part of the escape rope penetrates through the accommodating part, accordingly, the escape rope continuously slides in the accommodating part, and second pull force is larger than first elastic acting force. In cooperation with the design of the safety belt and the special escape rope, people in the high place where an aerial ladder cannot reach can be helpedto rapidly and safely escape.

Description

technical field [0001] The invention relates to fire-fighting equipment, in particular to a simple and practical high-altitude escape device. Background technique [0002] With the rapid development of urbanization in the country, there are many high-rise buildings, and high-rise buildings with 30 or 40 floors abound. Especially in modern metropolises, there are more and more skyscrapers, and the fire hazards of high-rise buildings increase accordingly. Once a fire breaks out, it is difficult for fire-fighting aerial ladders or large-scale fire-fighting aerial ladders to meet the needs of firefighting and helping people escape from heights, and their safety is also worth considering. Contents of the invention [0003] Therefore, one of the objects of the present invention is to provide a simple and practical high-altitude escape device, which can help people who cannot reach high places with fire-fighting ladders quickly and safely escape with the design of safety belts an...
