Lifting type escaping device and driving mainframe thereof

Abstract

The invention discloses a lifting type escaping device and a driving mainframe thereof. The driving mainframe comprises a main shaft, a mounting seat, an energy storing unit, a power unit, a speed reduction unit and a pre-tightening force adjusting unit, wherein the energy storing unit comprises a volute spiral spring and a spring mounting housing; two ends of the volute spiral spring are correspondingly fixedly connected to the main shaft and the spring mounting housing; the power unit comprises a coiling block and a steel wire rope; the coiling block is fixedly connected to the spring mounting housing; the speed reduction unit comprises a friction housing, a planetary gear, an acceleration disc gear and a centrifugal frictional block; the centrifugal frictional block can centrifugally move to be in contact with the friction housing so as to realize frictional energy consumption and speed reducer; the pre-tightening force adjusting unit comprises a turbine and a worm; the turbine is fixedly connected to the main shaft in a rotating stopping manner; and the worm can drive the main shaft to rotate through the turbine so as to adjust the pre-tightening force of the volute spiral spring. The lifting type escaping device and the driving mainframe thereof are pure mechanical devices and are stable and reliable in performances and are hardly failed in hazards such as fire; and moreover, the convenience of mounting, debugging and use is ensured.

Description

technical field [0001] The invention belongs to the technical field of high-rise escape equipment, and in particular relates to a lifting escape equipment and a driving host thereof. Background technique [0002] With the rapid development of the economy, there are more and more high-rise buildings in the city, and there are more and more disasters such as fires and earthquakes. Escape from high-rise buildings has become an urgent problem to be solved. Most of the existing escape devices for high-rise buildings include electrical components, resulting in low reliability of their work, and they are prone to failure due to power failure or electromagnetic interference in fires and other disasters. Moreover, the mechanical structure of escape devices is complicated and difficult to install and debug. And use, and the escape crowd is uneven, including the elderly, children, women, disabled people, etc. from the age structure, so the escape device cannot meet the operation of var...
