Description

Life saving device from fire disaster

The utility model is the improvement to the life-saving device for fire that is applied in high-rise building.

The instrument that is used for the fire of high-rise building lifesaving at present is the high-rise building device for rescue from building from fire.Its structure is that steel wire rope 1 is wrapped on two cylinders 12, mid portion adopts and turns the way that knob 13 promotes steel ball 15, push rod 14, moulding pad 16, make the direction motion of friction plate 17, steel wire rope is pushed against on the friction plate 18, reach the purpose that clamps the steel wire rope control rate to steel wire rope.The shortcoming of this structure is, complex structure, and it is unreliable to handle, and uses dangerously, is difficult to control rate during practical application.It is very inconvenient to turn knob in the air at height, and utilizes knob to clamp steel wire rope and control decrease speed and implement and be difficult to control, and knob has revolved tightly, and the easy pinch off of steel wire rope if revolve to such an extent that clamping is not in place, does not reach slow purpose of falling; Its component wear is big, and ordinary person is difficult to operation.

The purpose of this utility model is the shortcoming that overcomes above-mentioned brucker survival capsule structure, and a kind of easy operation is provided, safe and reliable, simple in structure life-saving device for fire.

The purpose of this utility model is to realize like this.Steel wire rope 1 one ends are connected with hook 10, and steel wire rope is wrapped on the helical axis 8.The helical axis middle part is the steel wire rope spiral slide, and two ends are screw thread; Between the screw thread of one end and the spiral slide cylinder convex, the other end side of being body convex; There is the hole, garden upper handle 3 lower ends, and with the Cylinder convex hinge joint of helical axis one end, external application nut 7 is threaded with helical axis; There is square hole lower handle 9 upper ends, are connected with the square body convex of helical axis one end, and external application nut 7 is threaded with helical axis, the one that cannot not become rotatablely.Upper handle can be turned back to the direction of lower handle around helical axis, forms to fold, and is easy to carry.Cam shank of the key 5 and spring 6 have two.Each cam shank of the key one end is an eccentric cam, respectively by bearing pin 4 and upper handle and lower handle hinge joint.Spring is stuck on lower handle and the cam shank of the key; make it to open, the eccentric cam of shank of the key termination part is slightly clamped steel wire rope with the end of handle like this, when steel wire rope during to the direction relative motion of helical axis; by the cam auto lock, reach the purpose of safeguard protection.Oppositely during relative motion, eccentric cam does not have locking effect.Hold handle and shank of the key during use, holddown spring, cam clamp to be decontroled, and shank of the key convex and handle are clamped the speed of steel wire cable by the size control human body decline of grip.Porose on the upper and lower handle.

Steel wire rope 1 one ends can be connected with hook 10.The hole of last lower handle can be connected with link 2, can be equipped with handle hook 11 on the link, or upward the hole of lower handle directly connects handle hook 11.

The utility model is certain bearing that the upper end of steel wire rope is hung over building, and on parts, the handle link connects a rope and hook, hangs on people's the waist with the human body gravity load.Hand is not bearing the situation lower-pilot brucker survival capsule of body weight.The utility model has adopted the damping of cylindrical screw wound form, and the steel wire rope winding number of turns is many, makes this end of steel wire rope that needs to clamp control reduced by pulling force, utilizes lever principle, obtains needed clamping force with the less power of holding, and the component wear of generation is very little.Like this can be by the grip control frictional force of hand, the size of frictional force has been controlled decrease speed, holds with a firm grip fully, has also just stopped decline.The utility model considers also that in design the people is after suspension, begin to fall and,, generally will firmly grasp the object in the hand if the people produces tense situation in the air at height in the aerial tense situation that produces of height, the handle of will holding with a firm grip naturally like this, thus reach the purpose of slow-down.As might out of control situation taking place, adopted the eccentric cam self-locking device technically.If the generation out-of-control condition by the motion and the gravity of human body decline, drives eccentric cam and rotates from trend locking direction, realize auto lock, people's cognition is parked in aerial, prevents to fall, and has an accident; Glide as needs,, can continue downhill race as long as hold fixed handle.

The utility model is saved oneself and he rescues two functions.

Save oneself: steel wire rope is wrapped on the cheese.During use, the operator hangs over the hook 10 of brucker survival capsule on the fixture of building, and cheese is put to ground, brucker survival capsule lower handle hook 11 is hung on the body of oneself again, holds down the Square handle control rate, just can drop to ground safely.

He rescues: can not handle old man, children and patient under the situation of saving oneself, can by other people use this brucker survival capsule with its let-down to ground, but repeated multiple times is used lifesaving.The lifesaving personnel hang over the end of brucker survival capsule near cheese on the fixture of building, again the hook 10 of steel wire rope is hung on one's body the personnel that rescued by safety belt or other bands, at this moment the lifesaving personnel hold Square handle control decrease speed on the brucker survival capsule, will be put into ground by the personnel of rescuing.

The utility model utilizes the mode that steel wire rope twines the garden post to increase damping, and is simple in structure; Adopt hand held braking control, easy operation; The cam self-locking mechanism is arranged, and it is safe and reliable to operation; Can fold, easy to carry; And save oneself and he rescue two functions.The utility model can be determined length of steel wire rope according to the height of building.
