Abstract

The utility model provides a life-saving apparatus for high buildings, comprising a damping device and a rope reeling device. The working principle is that the frictional force generated by the damping device is utilized to control the descending speed of human body, and ensures that human body can safely reach ground. The damping device is composed of flexible cable damper, a drum type brake, a weight auto-balance device and a centrifugal speed limiter. Because the human body weight is greater than the frictional force generated by the damping device and the weight auto-balance device, the human body descends. When the speed is over than the safely descending speed, a braking block is driven by the stay rod of the speed limiter to press a steel cable; then the frictional force is increased to control the descending speed of the human body. When the brake brakes, the human body is stopped in a space position.

Description

Life-saving apparatus for high buildings

The utility model relates to a kind of high-building life-saving device, and it is that the frictional resistance that utilizes damper to produce is controlled the speed that human body descends, and guarantees to arrive safely and reliably ground.Belong to high-altitude slow-descending lifesaving apparatus.

Along with development of times, building construction is tending towards high stratification gradually, and not only hotel, office block are very high, even the tens layers building that the resident lives is also more and more.High people is many in the building, in case the breaking out of fire accident, personnel's lifesaving upstairs is a problem very difficult to manage.Using helicopter rescue, is not that the thing of accomplishing easily slides along water pipe, rope, not only needs courage, and also difficult control rate is abnormally dangerous.

The purpose of this utility model, provide a kind of safe, high-rise building life saving apparatus easily, promptly be to have to save oneself and he rescues dual-use function, can control the human body decrease speed automatically in safety decrease speed scope, and can control a kind of brucker survival capsule that brake activation lever is realized braking.

The utility model is achieved in that

High-building life-saving device is made up of damping unit and cord winder two parts, and damping unit is made of gentle rope damper, drum brake, weight autobalance and centrifugal speed limiter four parts:

Fig. 4 is the centrifugal speed limiter vertical view of high-building life-saving device

Fig. 5 is resistance cercoids force analysis figure

From the total figure of Fig. 1 brucker survival capsule outward appearance, see, steel wire rope 14 upper ends are B for the A lower end, on steel wire rope the right is another weight balancing steel wire rope 3, and steel wire rope 3 two ends have wire line shoe 11 and the heart collar 12, limiter of speed loam cake 26, brake operating lever 9 all to be installed on the brucker survival capsule housing with screw.

Fig. 2 is the brucker survival capsule cut-away view, sees that from figure brucker survival capsule is made up of gentle rope damper, drum brake, weight autobalance and centrifugal governor four parts.

1, gentle rope damper is made up of steel wire rope, damping wheel cord winder, and steel wire rope 14 is walked around two damping wheels 4 and linked with the foreign volume rope device.

2, drum brake is to be made of cydariform brake block 7, weight balancing regulating wheel 8, brake operating lever 9, control stick 9 rotates with regulating wheel 8 and connects, and cydariform brake block 7 is fixed on control stick 9 left ends, moves the control stick right-hand member, the cydariform brake block is pressed to steel wire rope 14, the damping wheel stall.

3, the weight autobalance is to be made of weight balancing steel wire rope 3, limit rope column 1, brake pad pillar 6 and regulating wheel 8, be weight balancing steel wire rope 3 from top to bottom through two limit rope columns 1, two brake pad pillars 6, weight balancing regulating wheel 8, varying in weight and regulate frictional force on the damper automatically with the user.

4, centrifugal governor is to be made of limiter of speed axle 18, connecting rod 15, governor sheave 20, bearing 22, bearing outside 21, be that the speed limit rope sheave is installed on the axle 18, bearing 22 is installed in the two ends of axle 18, on steel wire rope 14 and the rope sheave, the speed that is driven the governor sheave rotation by steel wire rope is 1.5 meter per seconds, if decrease speed hypervelocity, centrifugal 24 produces enough centrifugal force in the limiter of speed, this centrifugal force forms moment of friction, make driving lever 19 act on brake pad 5 and press to steel wire rope and damping wheel, the frictional force summation is increased, thereby reach speed limit.

Fig. 3, Fig. 4 are the centrifugal speed limiter structure charts, see that from figure limiter of speed 13, speed limit rope sheave 20 are installed on the axle 18, at the two ends of axle bearing 22 is installed, steel wire rope 14 is stuck in the rope sheave groove, driving lever 19 is fixed on the limiter of speed shell, and centrifugal 24 usefulness pin 25 is installed on the limiter of speed shell.

Fig. 5 is damper force analysis figure, shows from figure: establishing human body weight is Q, and the relational expression that acts on power P ' on the gentle rope damping wheel I and Q ' is as follows:

Q′＝P′e ^－f。α

α is cornerite f in the formula.Be coefficient of friction

Get α=2 π f.＝0.15

Q '=e then ^{-0.15×2π。p′}

If Q=0.39P is P ＇=Q Q ＇=0.39Q

Through gentle rope damping wheel II, human body gravity is balanced a part again again, so through the damped frictional force institute balance that is produced of taking turns of the resistance of two damping wheel human bodies, the acceleration that produces when old friend's body descends reduces thereupon.

When using high-building life-saving device to save oneself:

1, with the opening of hook of steel wire rope one end, steel wire rope on fixtures such as steam heating pipe, is pinned with hook then, an end of steel wire rope is fixed.

2, the cord winder with the brucker survival capsule other end unclamps, with steel wire rope from upstairs putting to ground.

3, the person of saving oneself fastens safety belt, and in the heart cover annular distance that hangs over damper, hand-held damper begins down slow falling, and can brake by the stay cord brake activation lever, make human body be still in any position, space, unclamp the cydariform brake block, human body can continue again to descend.

Use high-building life-saving device he when rescuing:

1, utilizes the hole on the heart collar on the damper, damper is fixed in outside window or on the balcony of building, and makes damper be in vertical position.

2, cord winder is unclamped, be convenient to unclamp steel wire rope.

3, should be fastened seat belts by the rescuer, with the hook on the brucker survival capsule, hook the ring on the safety belt, can be descended by the person of rescuing, needing braking is to be handled by upstairs rescuer.

Advantage of the present utility model:

1, has and save oneself and dual property that he rescues, can not from the normal channel person of being out of danger, only need to use this brucker survival capsule can realize saving oneself or giving first aid to other people to escape danger in the high rise building emergency feelings.

2, brucker survival capsule is owing to be equipped with flexible cable damper and human body weight autobalance, so that damper is slightly less than the gravity of human body, the minimum assurance on the human body basic near uniform descent of acceleration that old friend's body produces to the frictional resistance of steel wire rope.

3, because the effect of centrifugal speed limiter guarantees the human body decrease speed less than safety speed, descend such as human body and exceed the speed limit, limiter of speed works at once, so use this brucker survival capsule reliable.

4, this brucker survival capsule multiple functional, simple in structure, easy and simple to handle, cheap, be easy to promote.
