Abstract
A double-rope hydraulic damping descent control device is mainly composed of a cylinder sleeve, an end cover, a left descent control rope, a right descent control rope, a left rope winding wheel, a right rope winding wheel, a left rotating shaft, a right rotating shaft, a left blade, a right blade, damping liquid and the like. One end of the left descent control rope and one end of the right descent control rope are connected with a person or an object which needs to descend slowly. The left descent control rope and the right descent control rope are reversely wound on the left rope winding wheel and the right rope winding wheel respectively. The person or the object drives the left descent control rope and the right descent control rope when descending. The left descend control rope and the right descend control rope make the left blade and the right blade oppositely rotate in the space composed of the cylinder sleeve and the end cover through the left rope winding wheel, the right rope winding wheel, the left rotating shaft and the right rotating shaft respectively, wherein the space is filled with damping liquid. The momentum generated when the damping liquid moves impacts on the left blade and the right blade, the left blade and the right blade generate opposite torques, and therefore the aim of slowly descending the person or the object at a constant speed is achieved. The descent control device has the advantages of being simple in structure, safe, reliable, low in manufacturing cost, durable in use and the like.
Description
Technical field
The present invention is a kind of duplex type hydraulic damping descending lifeline, belongs to fire-extinguishing and lifesaving equipment.
Background technology
Its structure of the escaping descent control device of existing use is varied, but the defect such as all ubiquity poor stability, complex structure, manufacturing cost be high.As poor in friction eceleration agency security, be afraid of oil, water funk.Chain type reducing gear complex structure, manufacturing cost are high, noise is very much not steady.Single rope hydraulic damping reducing gear structure knot is complicated, manufacturing cost is high must configuration gearbox.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of duplex type hydraulic damping descending lifeline for the deficiencies in the prior art.
The technical solution adopted in the present invention is: duplex type hydraulic damping formula descending lifeline primarily of cylinder sleeve, end cap, left rope-winding wheel, right rope-winding wheel, left slow fall rope, rightly slowly fall rope, sealing gasket, sealing ring, left-hand rotation moving axis, right rotation shafts, lobus sinister sheet, lobus dexter sheet, damping liquid and connecting bolt formation.Several lobus sinister sheet is connected with left-hand rotation moving axis, and several lobus dexter sheet is connected with right rotation shafts, is arranged on respectively in space that cylinder sleeve and end cap formed, fills damping liquid in this space.End cap is connected with cylinder sleeve by bolt, turns left and right axle and is supported by left and right end cap.Damping liquid can be the liquid such as oil or water.Left slow fall the left-handed or dextrorotation of rope and be wrapped on left rope-winding wheel, left rope-winding wheel is arranged on left-hand rotation moving axis, and left slow rope one end that falls connects the people or object that must slow fall by jockey, jockey can be hook, escape compartment etc.The right slow rope that falls is wrapped in that its winding direction and a left side on right rope-winding wheel are slow to fall rope to be wrapped in left rope-winding wheel direction contrary, and right rope-winding wheel is arranged on right rotation shafts, and right slow rope one end that falls connects palpus by jockey and delays the people or object that fall.Take this, fall Shi Zuohuan and fall rope and the right side when people or object are slow and delay and fall rope and pull respectively and turn left and right axle anti-phase rotation each other.Turning left and right axle drives several lobus sinister sheet and several lobus dexter sheet to rotate backward each other, left and right blade drives damping liquid anti-phase motion each other, the momentum that damping liquid produces impacts left and right blade, and make left and right blade produce opposing torque, opposing torque is delivered to and turns left and right axle.Opposing torque with turn left and right axle rotating speed increase and increase.When opposing torque and the slow people that falls or object to turn left and right torque that axle produces equal time, the people of decline or object decrease speed are no longer accelerated thus reach constant speed to delay the object of falling.When delaying the people fallen or object decline, the left and right slow other end rising descending lifeline falling rope reciprocally uses simultaneously.
Duplex type hydraulic damping descending lifeline lobus sinister sheet right-hand member arranges groove, and lobus dexter sheet arranges the groove coupling of boss and lobus sinister sheet at left end, when lobus sinister sheet and lobus dexter sheet are less than 3mm in gap between same plane position lobus sinister sheet and lobus dexter sheet.Like this because left and right blade stagger is arranged so that the resistance of damping liquid to left and right blade movement is larger.
Duplex type hydraulic damping descending lifeline is high to blade malleation its retardation efficiency of slowing down by the liquid moved, and therefore it has the features such as rational in infrastructure, safety and steady, noiseless, low cost of manufacture are durable in use.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is a preferred embodiment of the present invention structure sectional view.
Detailed description of the invention
See Fig. 1 and Fig. 2, this duplex type hydraulic damping descending lifeline primarily of cylinder sleeve 1, end cap 2, left rope-winding wheel 3, left slow fall rope 4, right rope-winding wheel 5, rightly slowly fall rope 6, sealing gasket 7, sealing ring 8, left-hand rotation moving axis 9, lobus sinister sheet 10, right rotation shafts 11, lobus dexter sheet 12, damping liquid 13 and connecting bolt 14 and form.6 lobus sinister sheets 10 are connected with left-hand rotation moving axis 9,6 lobus dexter sheets 12 are connected with right rotation shafts 11 and are arranged in container that cylinder sleeve 1 and end cap 2 form respectively, damping liquid 13 is filled in this container, left slow fall that rope 4 is left-handed to be wrapped on left rope-winding wheel 3, left rope-winding wheel 3 is arranged on left-hand rotation moving axis 9, and left slow rope 4 one end that falls connects the people or object that must slow fall, and rightly slowly falls rope 6 and is wrapped on right rope-winding wheel 5, right rope-winding wheel 5 is arranged on right rotation shafts 11, and right slow rope 6 one end that falls connects the people or object that must slow fall.
