Device for rescuing from storied house

Abstract

The present invention discloses a building escape device and aims to provide a safe escape device for people above the second floor in the case of fire, earthquake and so on, when a normal passage can not be used for escape. For the device, the periphery of a rotating frame plate is connected with a rope groove, and a steel rope is wound in the rope groove. One end of the steel rope is connected with the rope groove, and the other end is connected to a firm object after passing a rope hole. The inner circumference of the rotating frame plate is connected with an inner wire wheel, and an external screw jacking pipe or an external screw jack is fit inside the inner wire wheel via a threaded sleeve. Hanging pipes are fit into two shoulders of the inner wire wheel in the flexible way, and are fixed with a fixing frame. The space enclosed by the fixing frame can meet the requirement for rotation of the rotating frame plate and the rope groove. The upper end of the fixing frame is equipped with the rope hole, and the lower end is equipped with a sling hanging a safety device for a person suspending in the air. One side of the fixing frame is equipped with a hydraulic cylinder, and a piston inside the cylinder is connected with a connector of the external screw jacking pipe or connected with the external screw jack externally. The external screw jacking pipe or the external screw jack is equipped with a keyway, inside which an anti-rotating key arranged on the hanging pipes lies. A liquid passage and a valve are arranged near the bottom of the cylinder. When the device is used, gravity of a person can be transferred into the pressure on the piston, and the falling speed of the person can be controlled by controlling the liquid outflow via the valve.

Description

technical field [0001] The invention relates to an escape appliance, in particular to a building escape device. Background technique [0002] There are more and more people who use buildings at present. Once the personnel above the second floor run into fire, earthquake etc. and cannot escape in normal passages, they need a kind of escape device that can be safely and quickly in abnormal passages such as windows and balconies.
