Abstract

The utility model relates to a safety life-saving apparatus which is mainly used for high building escape. The housing of the safety life-saving apparatus is cylindrical and is provided with supporting legs and hanging rings. A shaft which is respectively provided with a shaft roller and a speed limiter by bearings is supported by two end caps of the housing. The shaft roller is provided with an internal gear and a friction slot. The speed limiter is provided with a gear and a sector block. The shaft roller drives the speed limiter to rotated by an intermediate wheel. The speed limiter also controls the rotation speed of the shaft roller because of the centrifugal friction action of the sector block and the friction slot. A steel cable passes through a compressing wheel and a cable centralizing wheel and winds on the shaft roller, and then both ends of the steel cable extend out of the housing, so the steel cable and the housing can not slide relatively. In addition, both ends of the steel cable are provided with loading mesh-belts. The maximum load of the safety life-saving apparatus is 150 kg, and the descending speed of the safety life-saving apparatus is 2m-2.7m.

Description

Safety life-saving apparatus

Safety device for life-saving is a kind of mechanical device that is used as power by the weight of user own, and it is mainly used in high-rise life saving escape danger, and the recreation of also can parachuting is used.

At present, skyscraper does not have the special escape facility of escaping danger, meet catch fire, dangerous situation such as blast, be difficult to escape from, unique grade is rescued by the fire-fighting crane, often causes life and property loss.The function of this device is: with it people or thing are transferred to ground safety quickly from skyscraper.Full shaddock is installed one can be shared, or a special use is installed in one deck one Room.

The utility model purpose provides a kind of safety device for life-saving, and characteristics are to meet fire at skyscraper, and during dangerous situations such as blast, distress personnel can in time be jumped out and escape danger.

Accompanying drawing 1 is a full profile of the present utility model

Accompanying drawing 2 is A-B-C-D cutaway views of the present utility model

The utility model is constructed as follows: the flat garden of shell (2) tubular, and with supporting leg is installed. Suspension ring (1) are fixed on shell top, hang during use and carrying has left and right sides end cap (16), (6) to seal with, shell two ends. Axle (8) two ends are supported in the centre bore of end cap. Beaming roller (15) combines as a whole with ring gear (3), and dovetail groove and internal gear are arranged on the ring gear. Beaming roller is equipped with bearing in the hole, is installed on the axle. It is that tooth rest (7) and four secter pats (13) of cross form that limiter of speed has gear one end by an end, and secter pat freely is placed in the cross of tooth rest, and insert in the dovetail groove of ring gear in echelon the outer of secter pat. Tooth rest has bearing in the hole, is installed on the axle. Gear on idle wheel and internal gear and the tooth rest coincide simultaneously, so beaming roller is when rotating, and limiter of speed (comprising tooth rest and secter pat) also rotates simultaneously, but both opposite directions. Positive rope sheave (14) is screwed on left end cap (16), and freely is enclosed within on the beaming roller. The effect of positive rope sheave is to keep the axial location of steel cable on beaming roller. Stretch out the square hole under shell at the steel cable two ends, and there is the guipure that uses the manned thing of fashionable dress at the steel cable two ends. The fixing in the enclosure below of safety wheel (12), two safety wheels (11) are with coupling block 10) join together. Coupling block can be in the chute in insurance wheel seat (12) transverse shifting a little, the steel cable two ends are passed through between two safety wheels and insurance wheel seat respectively, the effect of safety wheel is that steel cable to the end that rises is with certain pulling force, make the steel cable and the beaming roller that are wrapped on the beaming roller that enough frictions be arranged, and non-slip.

During use, the guipure that the people fastens steel cable one end descends, because people's gravity effect, steel strip moving axis roller rotates, limiter of speed (comprising braces and secter pat) oppositely rotates simultaneously, and decrease speed is fast, and beaming roller rotates fast, limiter of speed rotates also fast, centrifugal of limiter of speed because of action of centrifugal force, press into producing frictional resistance in the dovetail groove of ring gear, because of beaming roller opposite with the rotation direction of limiter of speed, limited the decrease speed quickening, decrease speed is remained in the safety speed of regulation.First user's safety reaches second guipure continuation decline that the user fastens the steel cable other end again behind the ground, uses continuously so repeatedly.

This device uses and does not highly limit through test of many times, 150 kilograms of the maximum loads of once descending, 2.7 meters of maximum falling speed per second kinds.
