Abstract
Disclosed is a fire disaster lifesaving apparatus for high building, comprising a safety belt and is characterized in that an assembly pulley is fixed on the chest plate of the safety belt and the wheel axle of the drive wheel and the driven wheel of the assembly pulley is fixedly provided with a sprocket wheel; a drive wheel axle is provided with a crank handle and a steel cable reel is fixed on the back plate of the safety belt, and the steel cable in the reel is led into the assembly pulley through a guide wheel and the cable end is led out by the assembly pulley and a lift hook is fixed on the cable end; the lift hook is hooked on the pipe of the caliduct or other firm objects, and the escaper rotates the crank handle by hands, therefore, human body can land on the ground or safe locations from high position step by step. The utility model has small volume and can be placed any place and is convenient in use; the utility model has lower manufacture cost and can be allocated on high buildings with a large quantity.
Description
Technical field
The utility model relates to the fire of high-rise building escape device.
Background technology
At present, the skyscraper in city is in continuous increase, and the fire lifesaving problem of skyscraper seems very important.Existing fire of high-rise building lifesaving appliance volume is bigger, is installed on the specific positions such as top in building usually, when breaking out of fire, is difficult in time, plays a role effectively.
Summary of the invention
The purpose of this utility model is to provide individual's fire of high-rise building escape apparatus of use, as shown in drawings, the utility model comprises one by the hip band, waistband, presternal plate, the safety belt that postnotum and shoulder belt are formed, it is characterized in that on presternal plate, fixing an assembly pulley, assembly pulley is by driving wheel, follower and driven pulley are formed, driving wheel, the reel for rope of follower and driven pulley is a regular polygon, be fixed with sprocket wheel on the wheel shaft of driving wheel and follower, be connected with chain between two sprocket wheels, drive sprocket axle is equipped with crank, on the postnotum by support with fix a cable drum, fix a spring damping pin that can apply resistance on the support to the cable drum sidewall, on the hip band, be fixed with guide wheel, steel wire rope in the reel is introduced the assembly pulley of presternal plate by guide wheel, steel wire rope winds with one circuit on the reel for rope of each pulley of assembly pulley, and fag end is drawn by assembly pulley, fixes a suspension hook on the fag end.During use, put on safety belt, suspension hook is hooked on steam heating pipe or other the firm objects, survivor's both hands shake crank, and with the steel wire rope slow release, human body can progressively be reduced to ground or home from eminence.The utility model volume is little, can be placed on any position, and it is also comparatively convenient to use.The utility model cost is lower, can dispose in a large number at skyscraper.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pulley block structure schematic diagram;
Fig. 3 is a chain wheel rope shaft section schematic diagram;
Fig. 4 is a spring damping latch structure schematic diagram.
In the above-mentioned accompanying drawing: 1, suspension hook; 2, presternal plate; 3, crank; 4, crank lock pin; 5, assembly pulley wallboard; 6, chain; 7, steel wire rope; 8, guide wheel; 9, hip band; 10, waistband; 11, postnotum; 12, cable drum; 13, spring damping pin; 14, shoulder belt; 15, sprocket wheel.
The specific embodiment
Assembly pulley and cable drum are fixed on the presternal plate t and postnotum of safety belt with rivet, the driving wheel of assembly pulley, follower and driven pulley triangularity are arranged on the wallboard of assembly pulley, the reel for rope of pulley is a regular hexagon, and 35 millimeters of the length of sides can avoid steel wire rope from line slip.On the crank of drive sprocket axle lock pin is installed, corresponding pin-and-hole is arranged on the wallboard of assembly pulley, during downslide such as need stop, lock pin can being inserted in the pin-and-hole.Wirerope diameter is 6 millimeters, and is long 110 meters, but 2000 kilograms of load-bearing, 40 millimeters of guide wheel diameters.Fix a spring damping pin on the support, apply certain frictional force to the cable drum sidewall, freely rotating of retardance cable drum produces a tightening force to steel wire rope, makes it be in tension all the time, in case steel wire rope gets loose from guide wheel.
Claims (3)
1, the fire of high-rise building escape apparatus, comprise one by the hip band, waistband, presternal plate, the safety belt that postnotum and shoulder belt are formed, it is characterized in that on presternal plate, fixing an assembly pulley, assembly pulley is by driving wheel, follower and driven pulley are formed, driving wheel, the reel for rope of follower and driven pulley is a regular polygon, be fixed with sprocket wheel on the wheel shaft of driving wheel and follower, be connected with chain between two sprocket wheels, drive sprocket axle is equipped with crank, on the postnotum by support with fix a cable drum, fix a spring damping pin that can apply resistance on the support to the cable drum sidewall, be fixed with guide wheel on the hip band, the steel wire rope in the reel is by the assembly pulley of guide wheel introducing presternal plate, and steel wire rope winds with one circuit on the reel for rope of each pulley of assembly pulley, fag end is drawn by assembly pulley, fixes a suspension hook on the fag end.
2, according to the said fire of high-rise building escape apparatus of claim 1, the reel for rope that it is characterized in that pulley is a regular hexagon.
