Description
Technical field
The utility model relates to a kind of escape device for high-rise buildings when disaster takes place, particularly a kind of reciprocating descent control device that utilizes damped cylinder to delay decrease speed.
Background technology
Development along with society, the people who lives in high buildings and large mansions is more and more, for inherently safe being considered people also more and more pay close attention to the design research and development of escape device for high-rise buildings, particularly when the moment that disaster takes place, do not know how to tackle dangerous people among the high building and provide food for thought more in the face of being in.
In recent years, domestic and international many enterprises and individual had also carried out research to escape device for high-rise buildings and had improved, have in addition be pushed into market, this has also having of machinery control electronic, of a great variety comprising rope ladder, rope.But some escape distance of these escape devices is short, can't be used for high-rise life saving; Some is that disposable escape is used, and when running into many people and escaping, then needs rope woolding again, and it is very inconvenient to operate.
Chinese patent CN200720139704.2, a kind of slow descending device of hydraulic damping is provided, two ends at hydraulic cylinder are communicated with by oil pipe, in the middle of oil pipe, establish a valve, thereby by slow the falling of resistance realization that hydraulic oil flows in different cross section and produces, still the structure of this mode is complicated, and production cost is higher, the tie point of pipeline is more, has increased the probability that breaks down.
The when mounted hooks that adopt of existing descending lifeline more, fix by hook, screw or bolt mode, but should consider, scene in emergency, because be pressed for time or psychology flurried, people are difficult to find the position that is used for fixing, or find the instrument that is used for fixing, thereby have incured loss through delay escape time.
Summary of the invention

Described damped cylinder is two, rack-mount respectively position near the rotating shaft two ends, and the anglec of rotation of two slider-crank mechanisms that are connected with piston differs 90 °.
Described reel is two, and the direction that steel wire rope is reeled on reel is opposite.
Near the position of reel tension disc down is installed on support, is provided with spring behind the pressing plate in the following tension disc, the steel wire rope of reeling on pressing plate and the reel cooperates.
In the position near pulley on the support tension disc is installed, is provided with spring behind the pressing plate in the last tension disc, pressing plate cooperates with pulley.
Position near pulley on support is provided with two support rings, forms triangular support structure at the support ring leading portion by many adjustable bars, and every master link of support is formed by connecting by two rod members with a plurality of adjustment holes, and an end of close reel is provided with base.
Pulley to support ring is 1: 5～1: 20 at projector distance on the horizontal plane and support ring to the ratio of base projector distance on horizontal plane.
Described steel wire rope and horizontal line have an angle α, and wire rope roll has an angle of inclination beta, α≤β on reel.
A kind of reciprocating descent control device that the utility model provides, by in the piston of hydraulic cylinder, adopting the scheme of aperture, external communicating pipe and control valve have been cancelled, improve the reliability of equipment and reduced cost of manufacture, can release from Bernoulli equation, functional relation between pressure and the speed is a parabola, and pressure is the product of suffered gravity and aperture sectional area herein, promptly can compensate the variation of gravity by the mode of adjusting sectional area, but should see, what determine the parabola opening is the density of fluid, after promptly adopting comparatively dense fluid, speed is promptly more insensitive with the variation of gravity and sectional area, and is more even if gravity increases, and velocity variations increases not quite, and in the piston of hydraulic cylinder, adopt the scenario-frame of aperture more succinct, do not adjust according to everyone body weight before need not using, uses more conveniently, avoided the hidden danger that causes because of the connecting portion leakage yet.
Preferred version of the present utility model has two damped cylinders, the anglec of rotation of the slider-crank mechanism that is attached thereto has staggered 90 °, avoided the dead point of slider-crank mechanism like this, speed is more steady during slow falling, and avoids causing because of the variation of speed the winding of steel wire rope.
Steel wire rope is opposite in the direction that two reels twine, like this steel cable is slow fall in, another root is regained, thereby realizes continuously slow falling.Winding between the steel wire rope that tension disc can be avoided descending and rising on being provided with on the support, and be convenient to steel wire rope is penetrated in the groove of pulley; The following tension disc that is provided with, and the support master link has enough length, thereby reel has enough little width and steel wire rope and has enough thicknesses and make steel wire rope and horizontal angle α smaller or equal to the angle of inclination beta of wire rope roll on the reel, twine mutually when having avoided steel wire rope on reel, guaranteed steel wire rope marshalling on reel.
Support of the present utility model has adopted a lever construction that the arm of force is bigger, and the arm of force can regulate as the case may be, during use support is placed on the railing of balcony, and pressing weight then on base can use, very convenient.By bolting, perhaps be connected more reliable base with railing.
The utility model does not need the user to control in use fully, can realize continuously slow falling, and operates steadily, and safe and reliable, production cost is lower.
