Reciprocating escape device

Abstract

The invention relates to a reciprocating escape device which comprises a casing and a lifting mechanism, wherein the casing consists of a shell with a hook seat and a cover plate; the lifting mechanism comprises a roller with two side plates, a main shaft, an energy storage spring and a rope, the main shaft is supported on the shell, and the energy storage spring and the rope are arranged on the roller; a buffer seat is arranged on the outside of the cover plate, an unlocking sleeve sleeved on the main shaft is rotatably connected to a buffer spring seat and is opposite to a unlocking taper sleeve, the buffer spring seat is internally installed with a buffer spring, a locking seat with at least two radial sliding chutes is installed on one of the two side plates, sliders are arranged in each corresponding radial sliding chute, the inner side of a locking pawl articulated with the locking seat is connected with the sliders and the outer side is opposite to a ratchet; a brake bottom plate and a brake housing are respectively installed on the shell and the cover plate, a brake disc is connected with the brake bottom plate, and a cam on the inner side of a brake handle articulated with the brake housing is opposite to the brake disc. The reciprocating escape device provided by the invention has the characteristics that the structure is compact and simple, the operation is convenient and safe, and the rescue efficiency can be improved.

Description

technical field [0001] The invention relates to a reciprocating escape device, which belongs to the technical field of high-rise emergency escape equipment. Background technique [0002] With the strong development of the economy and population growth, the expansion and development of cities, high-rise buildings are also spread all over the world, and there are more and more natural disasters and geological disasters. The topic of escape from high-rise buildings has attracted global attention. [0003] A variety of escape devices for high-rise buildings have been disclosed in the literature at present, most of which have complex structures, and the escape crowd is uneven, including the elderly, children, women, disabled persons, etc. from the age structure. Satisfy various group operations. Furthermore, ordinary escape devices cannot be reused, which will affect the escape efficiency. At present, a high-rise slow-falling escape device that can be reused and can automatical...
