Description
Technical field
The present invention relates to a kind of escape and rescue descending lifeline, belong to lifesaving appliance or device technique field.
Background technology
In recent years, the city developed rapidly, and high building stands in great numbers, and fire also happens occasionally, and how to become present society masses' focal issue in fire from the eminence escape.Traditional fast-escape mode is for passing through rope ladder, and the facilities such as life chute are escaped, but these facility costs are high, takes up room large, uses inconvenience, and especially the old and the weak is inapplicable.
The most duplex types that adopt of present disclosed escape device are mutually around principle, and still, traditional duplex type is, poor stability low around the escape device reliability mutually, it are dropped into reality and have following shortcoming in using: 1, high aerial two easy tangle ups of rope; 2, falling speed is difficult to control; 3, rope generation sliding friction produces large calorimetric, and life line rubs easily that to cause people's tumble injury to be fallen residual.Although some escape device is provided with extra rope clamping device, improved reliability, this class escape device ubiquity the shortcoming of unnecessary waste of material, so at double increase the production cost of product, be unfavorable for promoting the use of.Quality time when back and forth using simultaneously same set of lifesaving appliance not only to waste disaster, and increase the danger coefficient that the people locates dangerous situation.In addition, the sizable part in above two kinds of escape devices does not have the function of voluntarily control speed, and survivor's psychological burden is heavy like this, is unfavorable for the enforcement of saving oneself.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of and save material, coefficient of friction is little and can control speed, reliability is high, a kind of escape and rescue descending lifeline of high safety.
Technical scheme of the present invention is as follows:
A kind of escape and rescue descending lifeline comprises housing, clamp mechanism and reducing gear, is provided with clamp mechanism and reducing gear in housing; Described clamp mechanism, comprise symmetrically arranged 1 pair of gear wheel, 1 pair of pinion and 1 pair of pulley, wherein 1 gear wheel and 1 pinion homonymy arrange, the gear wheel of homonymy is meshed with pinion, gear wheel is fixedly mounted in the housing by axle, and Large Gear Shaft During links to each other by connecting rod with pinion shaft; Pinion and the pulley coaxle of homonymy are installed together; Form a rope hole that connects between symmetrically arranged 1 pair of pulley; The angle of described connecting rod and level is acute angle;
Described reducing gear comprises 1 pair of dashpot, is installed in respectively the below of 2 gear wheels, and the plunger shaft of dashpot is fixedly mounted in the housing, and the piston end of dashpot is arranged in the cam path of gear wheel upper surface.
Described clamp mechanism also comprises symmetrically arranged 1 pair of fixed idler whell and 1 pair of movable pulley, wherein 1 fixed idler whell and 1 movable pulley homonymy arrange, fixed idler whell and the movable pulley of homonymy are tangent, fixed idler whell is fixedly mounted in the housing by axle, the fixed idler whell axle of homonymy links to each other by connecting rod with the movable pulley axle, form an auxiliary rope hole that connects between symmetrically arranged 1 pair of movable pulley relative up and down with described rope hole, the pinion shaft of homonymy links to each other by connecting rod with the movable pulley axle.The connecting rod of homonymy consists of three limits of parallelogram, can be when stressed deformation reduce distance between the relative pulley, and then step up rescue rope, improve the security of rescue.
Described escape and rescue descending lifeline comprises that also the eccentric cam arrangements for speed regulation are arranged on the below in rope hole, described eccentric cam arrangements for speed regulation, comprise and fix to clamp piece and movable clamp, fixing to clamp piece is fixedly installed on the housing, movable clamp is arranged on the housing by bolt, movable clamp one end links to each other with housing by spring, the other end of movable clamp and fix to clamp piece and be oppositely arranged.The piece that fixes to clamp in these eccentric cam arrangements for speed regulation is the normally closed state that steps up with movable clamp, be used for stepping up rescue rope, when the escape personnel need to descend, only need with hand down layback stretch out the rescue rope of housing, just can realize controlling voluntarily the purpose of decrease speed: the extruding that movable clamp is subject to rescue rope drives the spring deformation of an end, movable clamp and the distance that fixes to clamp between the piece increase, and increase decrease speed.
In housing, and be provided with fastener on the axis relative with the rope hole.
Top and bottom in housing are respectively arranged with fastener.The swing of avoiding rope under External force interference and producing has improved the safety coefficient of rescue run greatly.
Be fixedly installed the rescue rope sling on the described surface of shell.The rescue rope sling can be little size, is rescued personnel and can arrest to get effectively rescue by hand; The rescue rope sling can also be large size, is rescued personnel rope sling to be enclosed within loins, obtains effectively rescue; In addition the rescue rope sling can also be made the shape of the various suitable rescues such as school bag shoulder belt, all belong to protection scope of the present invention.
Operation principle of the present invention:
When escape and rescue, only need an end of rescue rope is fixed, the other end passes described rope hole, auxiliary rope hole and fastener, quilt is rescued personnel and the escape and rescue descending lifeline is fixedly linked, when descending escape, rescue rope moves upward with respect to housing, and pulley is under the drive of rescue rope and rotates counterclockwise, the pulley driving pinion rotates counterclockwise along gear wheel, and pinion drives gear wheel; The cam path that arranges owing to the upper surface at gear wheel links to each other with dashpot, has effectively stoped the too fast rotation of gear wheel, and then reduces by the decrease speed of the personnel that rescue on rescue rope.
The invention has the beneficial effects as follows:
1, escape and rescue descending lifeline of the present invention, use dashpot to slow down safely, clamp mechanism and reducing gear are connected with a joggle, greatly strengthened the safety coefficient that human body falls from eminence, the life-escaping slow-landing equipment that it is different from the past, reduce the sliding friction that in the past produced large calorimetric, fricative heat can make the aging quickening of steel wire rope, greatly reduce safety coefficient, the present invention has adopted has the rolling friction that contact area is little, frictional force is little, so not only reduce the friction consumption to rope, and can not produce excessive temperature, improved the service life of rope.
2, escape and rescue descending lifeline of the present invention also has the eccentric cam arrangements for speed regulation, makes the personnel's that rescued gliding speed controlled, and gliding speed is remained in the safety speed scope.
3, the present invention has adopted single rope-lowering, has avoided the winding of reciprocating type double cable, makes safety coefficient that lifting in a big way arranged.
4, the present invention has adopted fastener, not only avoids rope under External force interference and the swing that produces, has greatly improved the safety coefficient of rescue run.
5, escape and rescue device of the present invention, simple in structure reliable, easy to operate, fault is low, and escape and rescue is rapid, easily makes processing, and cost is low, is beneficial to very much promotion and implementation.
