Detailed description of the invention
Refer to Figure of description 1 and accompanying drawing 2, accompanying drawing is depicted as a kind of safe and reliable Hydrautic damping lifesaving descent control device that the utility model provides, and it is assembled by parts such as left cover 1, left lid 2, right lid 3, right cover 4, capping 5, central shaft 6, internal gear 7, central gear 8, planet pin 9, planetary gear 10, damping impeller 11, runner 12, friction plate 13, radiation air flabellum 14 and steel wire ropes and is formed.
Wherein, described left cover 1 and left lid 2 match and merge the first cavity of formation one Collecting Center gear 8, planetary gear 10, internal gear 7, and described right lid 3 matches with right cover 4 and merges the second cavity that friction plate 13 and runner 12 are accommodated in formation one; Match between described right cover 4 and capping 5 and merge the 3rd cavity that radiation air flabellum 14 is accommodated in formation one, match between left lid 2 and right lid 3 and merge the 4th cavity that damping impeller 11 is accommodated in formation one.
Described capping 5 is installed in right cover 4, concrete, and both are fixedly connected with by buckle or bolt, is provided with a sealing ring between the two.
The through left lid 2 of described central shaft 6, right lid 3 and right cover 4 are also rotatingly arranged in left cover 1 and capping 5, and by being supported on respectively, bearing in left cover 1 and capping 5 is rotating to be arranged in left cover 1 and capping 5 central shaft 6.Described internal gear 7 is articulated on central shaft 6, specifically, is be supported on central shaft 6 by pair of bearings; And described central gear 8 is fixed on central shaft 6.
Described planet pin 9 takes shape in left cover 1; Described planetary gear 10 is installed on this planet pin 9, and it is meshed with central gear 8 and internal gear 7 respectively.Described planet pin 9 is specially three, and it is the arrangement in equilateral triangle centered by central shaft 6.
Described damping impeller 11 is fixed on central shaft 6, specifically, is be fixed on central shaft 6 by a pair pin.This damping impeller 11 is made up of engineering plastics, is filled with damping oil between itself and right cover 4, capping 5.For avoiding damping oil to reveal, between described central shaft 6 and right cover 4, be filled with a hermetic oil seal near damping impeller 11 place.
Described internal gear 7 is provided with steel wire rope groove, and this steel wire rope groove is in the shape of the letter V structure.Described rope capacity is 10-200m, and its one end is wound in steel wire rope groove, and the other end extends outside cavity.Be positioned at immediately below steel wire rope groove and be provided with a pair directive wheel, this is installed between left cover 1 and right cover 4 directive wheel, thus makes steel wire rope flexible circulate at work.A steel wire rope through hole (non-label) is provided with further between described left cover 1 and right cover 4, one spring housing is installed in steel wire rope through hole, described steel wire penetrating this steel wire rope through hole and spring housing, thus prevent from steel wire rope from stretching at work or shrink occurring to be wound around flexural deformation.
Hydrautic damping lifesaving descent control device operation principle of the present utility model is as follows: lifesaving descent control device of the present utility model and the fixed hook be located in floor are connected and fixed, the waist that steel wire rope one end bundle is placed on human body tightens up, open window, the steel wire rope of rolling is lost to downstairs, requires that salvor then falls from window.In the moment of personal fall, steel wire rope is pulled by the Action of Gravity Field of personal fall, internal gear 7 is driven to rotate by steel wire rope groove, and drive three planetary gears 10 to do speedup rotation respectively, and drive central gear 8 quick rotation engaged with planetary gear 10, now be fixed on damping impeller 11 quick rotation on central shaft 6, and pressure is produced to hydraulic oil, hydraulic oil also produces reaction force to damping impeller 11, hydraulic pressure oil viscosity and make damping impeller 11 be subject to larger braking moment effect to the reaction force of damping impeller 11, force central shaft 6 to be a significant slowdown and do slow rotation, also do even underdrive by the internal gear 7 be meshed with planetary gear 10 simultaneously, until the speed that internal gear 7 spin down sets to personal fall, achieve Salvee person by steel wire rope slowly decline safety land.
Further, if in use hydraulic damping because certain reason malfunctioning (such as damping oil spills, or damping oil is overheated etc.), at this moment, the rotating speed of central shaft 6 is too fast, drive the faster rotational speed of runner 12, due to centrifugal effect, friction plate 13 outwards will skid off along film trap, friction plate 13 after skidding off receives the friction of outer wall and runner 12, under the drive of frictional resistance, make decrease speed slow to personal fall setting speed, also achieve Salvee person by steel wire rope slowly decline safety land.
By dual fail-safe, greatly reduce the fault rate of lifesaving descent control device, the probability met accident is excluded substantially, ensure that stability and the security of product.
Further, due in the process of high-altitude slow-descending, be no matter damping oil or friction plate 13 operationally, temperature all can significantly promote, what the radiator fan therefore in the utility model played is exactly the effect of lowering the temperature, in the process of rotating, hot gas is spread out of by louvre, reduces the temperature of whole descending lifeline.
By the setting of heat abstractor, solve descending lifeline affects its drawback run well in operation process because temperature is too high, product is more perfectly run.
In other embodiments, left lid 2, right lid 3, right cover 4 and capping 5 are provided with through hole, water pipe is through these through holes, water pipe is through the second cavity, the 3rd cavity and the 4th cavity, but avoid damping impeller 11, runner 12 and these devices of friction plate 13, lifesaving descent control device is provided with water tank, when lifesaving descent control device uses, water is always at water Bottomhole pressure, the whole lifesaving descent control device of further cooling, certainly also reduce the temperature of friction plate 13 and damping oil, further ensure stability and the security of product.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
