A safe and rapid escape device placed on the outer wall of a building with slide rails

Abstract

The invention discloses a sliding rail type safe and rapid escape device arranged at the external wall of a building and belongs to the technical field of safety of buildings. The sliding rail type safe and rapid escape device comprises a main support and a rail; the lower end of the rail is hinged with the lower end of the main support; a center rod part is placed in a gap between the main support and the rail; the lower end of the center rod part is in sliding fit with the rail; a steel rope motor is fixed to the upper end of the rail; the steel rope motor is connected with a first rope anda second rope; the other end of the first rope is connected to the main support; the other end of the second rope is connected to the lower part of the center rod part; a plurality of bearing slidingballs are installed inside a sliding passage of the center rod part; the bearing sliding balls are connected with a pull rope; an escape cabin is placed inside an escape window; and the escape cabin is connected with the pull rope. The sliding rail type safe and rapid escape device disclosed by the invention directly gives consideration to vulnerable groups including old people and children by adopting a window as an escape opening, prevents secondary injuries caused by a stampede accident under conditions such a fire, realizes a high escape speed, saves the escape time and also protects people from building dangers in an escape process.

Description

technical field [0001] The invention relates to the technical field of building safety, in particular to a safety and rapid escape device placed on a slide rail on an outer wall of a building for rapid evacuation of crowds. Background technique [0002] In emergencies such as fires that require emergency evacuation, the escape personnel in the building generally use the evacuation stairs in the building for emergency escape, but the evacuation stairs in the building itself have many shortcomings and are not very suitable for emergency escape. The disadvantages of evacuation stairs are: [0003] 1 The escape route is long and tortuous, which limits the escape efficiency and success rate in terms of escape time; [0004] 2 If the evacuation stairs are filled with smoke, fire, etc., it is difficult to undertake the task of evacuation; [0005] 3. If a large number of escapees flood into the evacuation stairs in an emergency, a stampede accident will easily occur and cause sec...
