Description
Technical field
The utility model relates to a kind of lifesaving descent control device, belongs to the lifesaving technology field.
Technical background
Lifesaving descent control device is a kind of high-altitude self-saving appliance in case of accident tool, and it is personnel in the skyscraper a kind of escaping tools when meeting dangerous situation such as fire, earthquake.Existing lifesaving descent control device not only volume is big, heavy, and sensitivity is low, has potential safety hazard.In existing lifesaving descent control device, there is a series products to belong to disposable product, this can increase user's use cost.Though another kind of product can be repeatedly used, under with situation once in danger, can only use escape for one person-time.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of lifesaving descent control device, and this descending lifeline is rational in infrastructure, safe and reliable, and can be for the escape successively at short notice of several distress personnels.
The utility model adopts following technical scheme:
The utility model comprises safety belt, steel wire rope, the support that base and base are fixing, group wheel and fixed pulley, it is characterized in that said mid-stent fixes a ring gear, ring gear is concentric with axle, axle lower end and base are fixed, outer and the ring gear engagement of the planetary gear of a pair of symmetric arrangement, it between the axis hole of interior pulley and terminal pad and axle matched in clearance, idler gear is fixing and concentric with a centrifugal pan, its axis hole and axle matched in clearance, intermittent grooves is established in centrifugal pan cylindrical border, establishes centrifugal in alternate groove, and centrifugal is matched with brake drum, brake drum is concentric with centrifugal pan, and its cylindrical and support are fixed.The two ends of steel wire rope respectively connect a safety belt.
The utility model good effect is as follows: lifesaving descent control device volume provided by the utility model is little, in light weight, rational in infrastructure, safe and reliable.Easy and simple to handle.This descending lifeline is applicable to place of public entertainment, above hotel, the 3rd buildings, dwelling house, restaurant, high-rise office building, machine-operated office building.

In the accompanying drawings: 1 safety belt, 2 steel wire ropes, 3 groups of wheels, 4 supports, 5 brake drums, 6 centrifugal, 7 centrifugal pans, 8 idler gears, 9 axles, 10 planetary gears, 11 housings, 12 connecting holes, 13 ring gears, 14 bases, 15 fixed pulleys, 16 terminal pads, 17 wheel shafts.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Referring to accompanying drawing, lifesaving descent control device provided by the utility model comprise safety belt 1, steel wire rope 2, base 14, with fixing support 4, group wheel 3 and the fixed pulley 15 of base 14, support 4 can be made of upper and lower two parts, fixing ring gear 13 therebetween, fixed form can adopt screw, nut to be connected and fixed, and also can adopt riveted joint or be welded to connect fixing.Ring gear 13 is concentric with axle 9, axle 9 lower ends and base 14 are fixing, two planetary gears, 10 outer and ring gear 13 engagements of symmetric arrangement, interior and idler gear 8 meshes, planetary gear 10 is fixing with wheel shaft 17, wheel shaft 17, interior pulley 15 are all fixing with terminal pad 16, and this place can adopt screw, nut to connect equally or the riveted joint mode is fixed.9 of the axis hole of fixed pulley 15 and terminal pad 16 and axles are matched in clearance.Idler gear 8 is fixing and concentric with a centrifugal pan 7, and 9 of its axis hole and axles are matched in clearance.Intermittent grooves is established in centrifugal pan 7 cylindrical borders, establishes centrifugal 6 in alternate groove, and centrifugal 6 is matched with brake drum 5, and brake drum 5 is fixing with the cylindrical and the support 4 of centrifugal pan 7 concentric brake drums 5.Housing 11 can be set up outside the support 4, product members can be protected like this, attractive in appearance again.
In order to make same lifesaving descent control device can respectively connect a safety belt 1 at the two ends of steel wire rope 2 for many people escape successively at short notice.
The utility model operation principle is as follows: 1 jump out of the building when escape when the escape personnel fastens one's safety belt, steel wire rope 2 is pulled, steel wire rope 2 to lower slider drives fixed pulley 15 rotations, planetary gear 10 is rotated along ring gear 13, and simultaneously, idler gear 8 that is meshed with planetary gear 10 and centrifugal pan 7 also rotate synchronously, it is slow more that the escape personnel spurs the speed of steel wire rope 2 downslides, the rotating speed of centrifugal pan 7 is also slow more, and centrifugal 6 centrifugal force is little, so the frictional resistance of 5 of centrifugal and brake drums is also more little.The speed that glides along with steel wire rope 2 accelerates, and centrifugal 6 centrifugal force also becomes greatly, makes centrifugal 6 frictional resistance with 5 of brake drums become big, thereby limits the too fast gliding speed of steel wire rope 2, reaches escape falls in the escape personnel by means of wire rope slow purpose with this.
When wirerope diameter of the present utility model is selected φ 3mm for use, safe load 18-100kg/ people uses height 5-100m, downhill race speed 0.5-1.5m/s.
The utility model using method is as follows:
During use, subsidiary standby cable wire connects together by connecting hole on this descending lifeline base 12 and indoor solid and reliable implements when dispatching from the factory with this utensil, as the metal caliduct etc., the long end of steel wire rope 2 can be launched smoothly; Fasten seat belts 1, hand is grabbed steel wire rope 2, glides towards the external side of Li Yanlou and escapes.After last people landed, the escape personnel of back can continue escape by means of the safety belt 1 of steel wire rope 2 other ends.Like this, use same slow falling in the high building of 30m to escape, can in 8min, make 20 people's safe escapes.
