Controllable centrifugal drum type high-rise descent control device

Abstract

The invention discloses a controllable centrifugal drum type high-rise descent control device. A winding wheel is connected with an accelerator mechanism which is connected with a centrifugal drum type brake mechanism, a manual brake mechanism and an automatic descent speed control mechanism are connected onto the centrifugal drum type brake mechanism respectively, and a fireproof steel wire is wound on the winding wheel through a lead hole in a machine frame. The controllable centrifugal drum type high-rise descent control device achieves automatic uniform-speed descent through the accelerator mechanism and the centrifugal drum type brake mechanism, achieves the purpose of slow descent, and is simple and easy to use. A speed regulation knob is controlled manually, a transmission control spring group is tensioned (loosened) so as to increase (reduce) pre-tightening pressure exerted on a brake block, and the purpose of increase (reduction) of automatic descent speed is achieved. A movable handle is controlled, a part of axial force generated by the movable handle is transformed into positive pressure which is perpendicular to a shaft and is exerted on the brake block to form a braking torque so as to achieve that descent can be stopped manually at any time in the descent process, no electric power is needed, the slow descent function is completed through mechanical transmission, and the controllable centrifugal drum type high-rise descent control device is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of a high-rise escape slow-down device, in particular to a controllable centrifugal drum type high-rise slow-down device. Background technique [0002] The self-rescue high-rise fire escape device escapes by itself when a fire breaks out in a high-rise, which saves the risk of waiting for rescue and increases the hope of escape. [0003] At present, the self-rescue type high-rise escape device mainly contains electric fixed type and portable two forms at home and abroad, and wherein, the most widely promoted on the market is a kind of high-rise reciprocating escape escape device. This kind of high-rise reciprocating escape slow-down device adopts a structure similar to that of a climbing rope buckle. It is composed of a fixed pulley, an escape rope, and a mountaineering buckle. It has disadvantages such as difficult to learn and unable to actively adjust the descending speed during the descending process. ...

Problems solved by technology

This kind of high-rise reciprocating escape slow-down device adopts a structure similar to that of a climbing rope buckle. It is composed of a fixed pulley, an escape rope, and a mountaineering buckle. It has disadvantages such as difficult to learn and unable to actively adjust the descending speed during the descending process.

The electric fixed type is powered by a motor to provide lifting power. This kind of escape device has the disadvantages of large volume, complex structure, and high cost, which is inconvenient to popularize. time is often useless

It can be seen that high-rise escape devices generally have problems such as safety, reliability, and lack of timeliness.
