Abstract
The utility model relates to a fire-fighting life-saving appliance, particularly relates to a self-life-saving device for fire-fighting in a high building, and the utility model is composed of a host machine shell body, a steel cable, a drive part and a sealing box body. The utility model is characterized in that a steel cable reel is arranged in a host machine shell body, and the sealing box body is connected with the vertical end surface of the host machine shell body. A piston mechanism is arranged in the sealing box body, a crank shaft is connected with a steel cable reel shaft hole and a connecting rod of the piston mechanism, and the sealing box body is full of liquid. The utility model has high safety factor, simple operation and long service life. The utility model can completely make use of human body self weight to carry out slow landing.
Description
The utility model relates to a kind of fire-extinguishing and lifesaving device, especially for the high building fire-proof self-help life-saving device of high building fire fighting lifesaving.
The existing device that is used for the high building fire fighting lifesaving has professional life saving buoyant apparatus, and this buoyant apparatus only is suitable for the professional person through training or use.The buoyant apparatus that the ordinary people saves oneself is also just like safety ladder, lifesaving rope etc., this equipment all needs a transmission and damping mechanism, what general its transmission and damping mechanism adopted is gear and friction plate, when friction plate acts on the steel wire rope,, will produce certain destruction to steel wire rope owing to produce higher heat, influence the service life of steel wire rope greatly, also caused certain potential safety hazard.When adopting friction plate to realize slowing down sinking speed in addition,, must increase the size of friction plate and friction pulley, will cause the increase of entire mechanism like this, bring certain difficulty to use in order to increase frictional force.
The purpose of this utility model is to provide a kind of both can realize slow landing, had higher safety coefficient, high building fire-proof self-help life-saving device simple in structure again.
The purpose of this utility model is achieved in that
A kind of high building fire-proof self-help life-saving device, it is that host shell, steel wire rope, running part and seal case are formed, and it is characterized in that being provided with in described host shell a steel wire rope reel; Described seal case is connected on the perpendicular end surface of host shell; Be provided with a piston mechanism in described seal case, a crank axle is connected on the connecting rod of steel wire rope reel axis hole and piston mechanism; In described seal case, fill with liquid, be provided with a damping hole in the bottom of described piston base or fluid cylinder.The axis hole place that is connected at seal case and host shell is provided with a sealing ring.Be provided with a liquid injection hole at the top of described seal case.In the liquid injection hole of described seal case, be provided with movable pressure-reducing valve.Be provided with an auricular appendage hole at the top of described host shell, in described earhole, be installed with a steel wire guide wheel.
Of the present utility model simple in structure, steel wire rope can not produce serious wear phenomenon during use, and the safety coefficient height can utilize the deadweight of human body to land slowly fully, and is simple to operate, long service life.The utility model also is particularly suitable in family using when people save oneself when in danger.

Accompanying drawing 3 is the left view of the utility model Fig. 2
Accompanying drawing 4 is the A-A cutaway view of the utility model Fig. 2
Accompanying drawing 5 is the structural representation of the seal case part of embodiment 2 of the present utility model
Be embodiment of the present utility model with accompanying drawing 1,2,3,4,5 below, the utility model be further detailed:
Embodiment 1: as shown in accompanying drawing 1,2,3,4, can add a cover a main frame cap 21 at the end face of host shell 1, establish suspension ring 30 at the outer surface of the bottom of host shell 1, be used for the carrier of carry people or thing.Be provided with an auricular appendage hole 33 at the top of host shell 1, in described earhole 33, be installed with a steel wire guide wheel 17; Steel wire guide wheel 17 can be contained on the guide wheel shaft 18, and fixing with nut 19.Steel wire rope 23 is drawn from the upper outlet 31 of host shell 1, is close to the somewhere that guide wheel 17 is hung on building and gets final product.Steel wire rope reel 9 in the host shell 1 relies on reel hold-down nut 20 and crank axle 2 to fix.In order to guarantee the sealing effectiveness between seal case 10 and the host shell 1, can add one deck gasket seal 11 in the end that contacts of seal case 10 and host shell 1, be provided with a sealing ring 16 at axis hole 29 places that are connected of seal case 10 and host shell 1.Piston mechanism integral body places fluid cylinder 3, in piston 6, be installed with a piston pin 7 and have snap ring 8 to block, the lower end of the connecting rod 12 of piston mechanism is socketed on the piston pin 7, is fixed on the connecting rod 12 by the sweep of the connecting rod cap on the connecting rod 12 13 with bent axle 2, and 14,15 is fixed-use bolt and nut.The bent axle frame 26 that is connected on the fluid cylinder 3 is used to support bent axle 2, and bent pedestal cap 4 is fixed on the bent axle frame 26 by screw 5.22 is sealing screw; 25 for connecting with nut and screw; Nut 24 is the fluid cylinder hold-down nut.
When using the utility model, the liquid of being adorned in the fluid cylinder 3 should be selected boiling point height, liquid that the coefficient of expansion is little.When using the utility model to save oneself, with safety belt with hanging over suspension ring 30 places, 23 safe places that hang over building of steel wire rope, the people can skid off from balcony or window, because the existence of piston mechanism, reduced the decrease speed of steel wire rope 23, made human body under the state of safety, to land, do not worried that also steel wire rope can be owing to excessive friction is ruptured.Seal case 10 should select the good material of heat conductivility to make, as metallic aluminium and stainless steel.Bottom at the piston 6 of described piston mechanism is provided with a damping hole 28, and damping hole can play the effect of bottleneck like this.Piston 6 will be extruded liquid at the volley in cylinder body, owing to liquid can only flow out from damping hole 28, so its motion is slower, thereby has reduced the decrease speed of steel wire rope 23.
Embodiment 2: as shown in Figure 5, in order to reduce the pressure that liquid in the seal case 10 is overheated because of taking place, expand and produced, can establish a movable pressure-reducing valve 32 at liquid injection hole 27 places at the top of described seal case 10.Described damping hole 34 is located at the bottom of fluid cylinder 3.Other parts of present embodiment are all identical with embodiment 1.
