Abstract

The invention discloses a self-return type coaxial descent control device comprising a base, a housing, a center shaft, a driving rope sheave, a sun gear, a one-way overrunning clutch, a friction brake wheel, a coil spring, a gear ring and three planet gears. A rope race used for winding a descent control rope is arranged in the middle of the driving rope sheave, the coil spring is mounted on the left side of the driving rope sheave, the sun gear is arranged on the right side of the driving rope sheave, and the sun gear and the driving rope sheave are integrated and rotate coaxially and synchronously. The three planet gears are connected with planet gear supporting plates through fixing shafts, and the planet gear supporting plates are connected and fixed with the housing. The sun gear is meshed with the three planet gears which are meshed with the gear ring, and an extension structure of the gear ring loosely sleeves the center shaft. The gear ring is connected with the friction brake wheel through the one-way overrunning clutch. The rotating components are designed coaxially, the integral structure is more compact and operates smoothly, the coil spring is utilized to timely withdraw the descent control rope, and convenience and safety in use are improved greatly.

Description

technical field [0001] The invention relates to a slow-down life-saving device, in particular to a self-returning coaxial slow-down device. Background technique [0002] At present, with the continuous acceleration of the urbanization process in our country, the continuous expansion of the city scale, and the continuous increase of high-rise buildings, but at the same time, various high-rise disasters and accidents also occur frequently. Today, with the improvement of people's living standards, people's awareness and measures for quality of life and life safety have also risen to a new requirement, and the demand for practical, economical, and easy-to-operate slow-down equipment is increasingly urgent. and quality put forward higher requirements. [0003] The driving sheave and the friction brake wheel of the existing friction braking type slow down device are respectively arranged on two shafts, and the disadvantage is that the operation is not stable enough and the volume...
