Abstract

The invention relates to a recyclable hydraulic damping descent control device with stall protection, and belongs to the field of emergency equipment of high-rise buildings. The device comprises a descent device, a speed changing device, a stall protecting device, a hydraulic damping device, an installing and fixing device and a shell, wherein the descent device, the speed changing device, the stall protecting device and hydraulic damping device are sequentially connected and installed in the shell; and the installing and fixing device is connected with the shell. The descent control device provided by the invention is of a mechanical hydraulic structure, has the characteristics of small size, high reliability, convenience in use and simplicity in maintenance, and is suitable for the descent and the escape from high-rise buildings in emergency circumstances.

Description

technical field [0001] The invention belongs to the field of high-rise building emergency escape equipment. Background technique [0002] The escape descent device (or life-saving descent device) is a device that relies on the user's own weight to descend safely or relies on the governor to provide damping, which limits the descending speed of the free end of the safety rope, allowing people to slowly descend along (following) the rope (belt). Safety escape device; the device includes parts such as governor, rope, connector and rope reel. At present, the vast majority of emergency descent devices for high-rise buildings use friction damping structures. This type of descent devices adopts the principle of friction braking: generally, the gravity of a person is converted into a frictional resistance that is balanced with gravity through a friction device. , to achieve the uniform descent of people, but this kind of mechanism has problems such as inconvenient adjustment, sudde...
