Multifunctional escaping descent control device

Abstract

The invention discloses a multifunctional escaping descent control device comprising a drive system, a wrap angle speed regulating system, an instant stop brake system, a shell and a safety belt, wherein the safety belt is detachably connected to the shell; a planet wheel drive mechanism of the drive system is arranged on a bottom board of the shell through a planet wheel support; a core shaft is arranged on the bottom board, a rope wheel is sheathed on the core shaft through a linked shaft sleeve, and a centrifugal speed stabilizing mechanism is connected with the planet wheel drive mechanism; guiding roller wheels of the wrap angle speed regulating system are arranged at both sides of the rope wheel and are at the same straight line with the edge of the rope wheel, one end of a pull rod is arranged on the linked shaft sleeve, and the other end is connected with a screw rod through a wrap angle rocking rod; and a brake pad of the instant stop brake system is arranged at the outer side of a centrifugal wheel, a brake block adapting to the brake pad is arranged at the outer side of the brake pad, the brake block and the brake pad are installed on the bottom board through a press cover, one end of the brake pad is fixed on the bottom board, and the other end is connected with a pull rope. The invention has the advantages of complete function, reliable quality, compact structure, simple and flexible operation and low cost and can meet the need of multi-user synchronous escaping.

Description

technical field [0001] The invention relates to a safety escape device, in particular to a multifunctional escape descent device used in high-rise buildings. Background technique [0002] With the acceleration of urban construction, more and more high-rise residential buildings, office buildings, commercial buildings, etc. appear in large and medium-sized cities across the country. These buildings provide services for our life and work, but the safety of the people in the buildings has become our unavoidable question. The fire broke out, the fire spread quickly, the elevator in the building was out of service, and the evacuation of personnel became the biggest problem. [0003] The world's first high-rise escape slow-down device was produced in Japan, an earthquake-prone country in the 1980s. It better solved the difficult problem of high-rise escape in distress. After the 9.11 incident in the United States, countries around the world began to set off an upsurge of researc...
