Description

A kind of descending lifeline
Technical field
The present invention relates to the fire-fighting equipment technical field, relate in particular to a kind of descending lifeline.
Background technology
Along with the Chinese society expanding economy, people's material life must improve, and high-frequency fire incident is also pressed hard step by step.Solve current high building fire fighting and bring into schedule, the high-rise emergency escape of personnel is very urgent with the safe escape problem.Present various descending lifelines exist bulky mostly, complex structure, cost of manufacture height, the perishable or slow shortcoming such as poor effect of falling.Application number is that 200710131815.3 Chinese invention patent discloses a kind of wire rope slow drop-down apparatus, comprise housing, steel wire rope, enclosure interior is provided with centrifugal friction formula deceleration device, its principle is to utilize centrifugal force to make brake pad and frictional disk fit to produce the rotating speed that frictional force limits pulley, this structure drives the rotation of flying disc by gear drive in drive pulley, its complex structure, in actual applications, tending to occur has foreign matter or gets rusty on the gear, and in situations such as carrying misplace between gear when mobile, it is stuck gear to occur, actual effect breaks down, when getting into danger the use descending lifeline, can not work, incur loss through delay the escape chance.
Summary of the invention
The present invention be directed to the shortcoming of above-mentioned existence, providing a kind of does not need by gear-driven mode, and it is simple in structure, and cost is low, the descending lifeline that reliability is high.
The technical scheme that technical problem adopted that the present invention solves is:
A kind of descending lifeline, comprise drive pulley, dead turn, be provided with the flying disc of band rotating shaft in the dead turn, flying disc is provided with the brake pad that can radially slide, brake pad can paste mutually with the dead turn face, it is characterized in that: be fixed with side plate and cover plate about dead turn respectively, side plate has one group of leading block, dead turn is provided with breach, leading block is positioned at indentation, there, drive pulley and the coaxial one of flying disc, and the middle part of side plate, cover plate and drive pulley and flying disc is passed in rotating shaft, rotating shaft is fixed on side plate, the cover plate, and drive pulley and flying disc can rotate in rotating shaft.During use, an end of steel wire rope is then walked around drive pulley from passing a leading block of dead turn indentation, there, draws from another leading block of dead turn indentation, there at last.The present invention adopts drive pulley and flying disc one, and the brake pad in the flying disc is realized slow falling by centrifugal action.When being affected under the gravity effect of steel wire rope the people, it drives drive pulley and rotates, and then rotate with the flying disc of drive pulley one, after the flying disc rotation, the brake pad that is arranged on the flying disc gets rid of cunning because of action of centrifugal force to avris, the brake pad edge pastes the dead turn face, produce the rotating speed of force of sliding friction restriction flying disc, limited the rotating speed of drive pulley so conversely again, to reach the slow purpose of falling of slowing down, the flying disc rotating speed is high more, the applying power of brake pad and dead turn face is big more, frictional force is just big more, and speed limit power is big more, realizes the slow effect of falling.The present invention is simple in structure, and parts are few, and is light small and exquisite, and not by gear-driven mode, safety coefficient and reliability improve greatly.Owing to do not adopt gear-driven mode, reduced maintenance, maintenance period simultaneously yet.
During concrete enforcement, the radian on the friction limit of brake pad is consistent with the radian of dead turn face, makes brake pad like this when reclining the dead turn face, and maximum friction area is arranged.
During concrete enforcement, flying disc is provided with symmetrical groove, and two suitable brake pads are located in the symmetrical groove of flying disc.
During concrete enforcement, flying disc is a cross, sets up the groove of four symmetries separately, and four suitable brake pads are located in four grooves of flying disc.
During concrete enforcement, one group of leading block is three pulleys, and three pulley arrangement are under side plate.During use, the steel wire rope of turnover is respectively by its adjacent pulley room.
During concrete enforcement, side plate and cover plate top are provided with suspension ring.Suspension ring play the effect of suspension.
During concrete enforcement, apparatus of the present invention can be provided with brake apparatus, can enable brake apparatus at the beginning in decline it is in the lock state, and this moment, rope can not be twitched, and the personnel that can prevent like this, avoid meeting accident once hanging on the phenomenon that safety belt begins to glide firm.After ready, brake off device lock-out state again, this moment, the people began to glide.In the decline process as when running into special circumstances and must stop falling, can realize the purpose of retarding braking again by brake apparatus.
The invention has the beneficial effects as follows: the present invention is simple in structure, and cost is low, and the reliability height can be widely used in emergency escapes such as high building, steamer, can be used for also that personal security on the helicopter descends and aspect such as rescue and relief work.
