Escaping pipe

Abstract

The invention discloses an escaping pipe. The escaping pipe comprises an indoor fixing frame (1), a bend (2) and a straight pipe (3); the indoor fixing frame (1) is fixed to the wall of a building and connected with the bend (2), the lower end of the bend (2) is connected with the straight pipe (3), and the straight pipe (3) is composed of a plurality of sections of double-wall corrugated pipes; two corrugated pipe sleeving structures are adopted in each double-wall corrugated pipe, the position between each outer-wall corrugated pipe body and the corresponding inner-wall corrugated pipe body is filled with a heat-resisting material, and crests of the outer-wall corrugated pipe bodies correspond to troughs of the inner-wall corrugated pipe bodies in parallel; flanges (4) are welded to the two ends of each double-wall corrugated pipe, every two adjacent double-wall corrugated pipes are connected through bolts by means of the flanges (4), and a buffer layer (5) is arranged on the inner wall of each double-wall corrugated pipe; and a safety hook is arranged at the top of the straight pipe, a descent control device is fixedly connected to the safety hook, and a buffer air cushion (6) is arranged at the bottom of the straight pipe (3). When the escaping pipe is used, the escaping efficiency is high, the flame retardant property is good, and the safety of a person during escaping is guaranteed.

Description

technical field [0001] The invention relates to an escape device, in particular to an escape pipeline. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. Seven to eight million fires are registered every year in industrialized countries, and the economic losses caused by fires in these countries account for 1% of their gross social product. At present, the domestic use of descending device as an escape tool has a simple structure, but the escape efficiency is poor. Foreign escape products such as slides or slides, but the material of the slide has poor flame retardancy, fear of being scratched by sharp objects, and has disadvantages such as low safety factor. Contents of the invention [0003] The object of the present invention is to provide an escape pipe, which not only has...
