Abstract
The utility model relates to a lifesaving slow falling device. The middle of a slow falling device body is provided with a central wheel shaft provided with a central wheel sheet and external teeth of the central wheel shaft; an engaging auxiliary shaft is formed by the external teeth of the central wheel shaft and the external teeth of two rope wheels and is connected in a casing. Three guide wheels are arranged under the rope wheels. After winding wheel slots of the two rope wheels to be crossed, the wire rope forms a motion pair with the guide wheels and is led out from the lower end of the body, and both ends of the wire rope are respectively provided with a safety belt. The interior of the central wheel sheet is provided with a friction block which is axially connected in a friction cover and forms a friction pair with the inner wall of the friction cover; frictional damping is generated by the friction block and the friction cover through centrifugal action to control the falling speed of the human body. The utility model has the characteristics of simple structure, small volume, uniform speed slow falling and repeated use; the utility model is an escape self-help tool for high buildings, such as a hotel, an office building, a shop, a residential building, etc.
Description
Technical field:
The utility model discloses a kind of lifesaving descent control device, relates to skyscraper self-help apparatus technical field.
Background technology:
At present, when high-rise occur dangerous situation as: when fire, earthquake, people often can't normally leave the scene of the accident, particularly be blocked under the situation about can't use at elevator ﹠ stairs, can only try every possible means to drop to ground from window, balcony and roof escapes, but usually because of can not find suitable escaping tool human casualty accident takes place, cause unnecessary loss.
Summary of the invention:
The utility model provides a kind of lifesaving descent control device, and purpose is intended to solve on the skyscraper people's the escape problem of saving oneself, have simple in structure, the little at the uniform velocity slow characteristics of using repeatedly of falling of volume.
Technical solution of the present utility model is as follows: the descending lifeline body is made of housing and friction outer cover, part device has center-wheel arbor in the body, center-wheel arbor is provided with center-wheel arbor external tooth and centre wheel sheet, center-wheel arbor external tooth and two rope sheave external tooths constitute Meshing Pair and are coupling in housing, below rope sheave, be provided with three directive wheels, the race intersection back that steel wire rope is walked around two rope sheaves constitutes kinematic pair with directive wheel, and draws from the lower end of body, and the steel wire rope two ends are respectively equipped with safety belt; The centre wheel sheet is the fan groove structure, and device has brake pad to be coupling in the friction outer cover in it, and brake pad constitutes friction pair with the inwall of friction outer cover.
Race on the rope sheave is a V-type, and angle is 6～10 degree, and is best with 8 degree.
Utilize two rope sheaves to make it take turns external tooth and the centre wheel external tooth is connected with a joggle, and pass through the brake pad of dress in the centre wheel fan groove and rub outer cover generation frictional force, make steel wire rope produce frictional resistance, steel wire rope drives two rope sheave rotations by the v-angle frictional force of rope sheave during work, the rope sheave external tooth connects drive centre wheel quick rotation by the centre wheel external tooth, brake pad in the centre wheel radially slides owing to action of centrifugal force, the pressing friction outer cover produces frictional damping, lifting capacity, centrifugal force and damping are directly proportional, thereby control its decrease speed at the uniform velocity, the thing acceleration produces, and has guaranteed people's safe falling.
Good effect of the present utility model is: adopt device brake pad structure in the centre wheel, make itself and friction outer cover produce frictional damping by centrifugal action, thereby control human body decrease speed, have simple in structure, the little at the uniform velocity slow characteristics of using repeatedly of falling of volume.Global design has taken into account bearing capacity, and is safe and reliable, uses simple small volume and less weight, is the ideal tools that hotel, office building, shop and the escape of residential building contour level building are saved oneself.
