The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the weight descending lifeline is made up of lifting rope 1, lifting rope reel 2, support 11, shell 12 etc., and lifting rope reel 2 two ends are connected with a rotating shaft 3 respectively, and rotating shaft 3 is linked to each other with piston 7 by crank 4, connecting rod 5 and connecting rod pin 6, be with cylinder barrel 8 on the piston 7, cylinder barrel has for 8 times pore 9 to link to each other with receiver 10.
Shell 12 is fixed on eminence, and weight hangs on the lifting rope.When weight descended, lifting rope 1 drives lifting rope reel 2 and rotating shaft 3 is rotated, and makes piston 7 moving linearly in cylinder barrel by 4 drivening rods 5 of the crank in the rotating shaft again.Like this, just the motion that weight is descended has been transformed into the continuous linear reciprocating motion of piston.
Piston is done when motion in cylinder barrel, force the pore of liquid between cylinder barrel and fluid reservoir to flow out or flow to.The fluid resistance that pore forms of flowing through plays a part to hinder piston motion, just plays a part to hinder weight and descends.
The channel sized that changes pore 9 can change the size of resistance.If the pore channel sized is made and can be regulated, just can regulate the weight descending speed.When the passage of pore was big, the weight descending speed was very fast; The passage of pore hour, the weight descending speed is slower; If close pore fully, the weight descending speed is zero.In addition, by regulating the pore passage, also can make the weight of its suitable different quality.
Adopt the liquid of different viscosity, can obtain different resistances.If change liquid into air, just do not needed receiver.Because air viscosity is less, need do pore forr a short time, just has enough resistances.Can make portable weight descending lifeline in this way, more be applicable to open-air the use.
Weight by gravity in the weight descending lifeline moves downward in the process, and the gravitional force of weight is by the local loss in the resistance of flow of liquid and the flow of liquid process, diffusion loss, along the loss of journey friction loss homenergic with become heat exhaustion and fall.
As shown in Figure 2, the crank 4 of the weight descending lifeline two ends and the set pore 9 that can be installed on rotating shaft 3 can be positioned at cylinder barrel 8 two ends.
As shown in Figure 3, if use the weight of weight descending lifeline slow fall highly certain, the reciprocating type lifting rope of then available band weight hook.When the weight hook that hangs over weight one side dropped to the destination with weight is slow, the weight hook of opposite side was together got back to lifting rope reel place with lifting rope.Do not need like this weight is slow drop to the destination after the rollback lifting rope.Can down carry weight repeatedly in more convenient ground, save time.
As shown in Figure 4, if use slow the falling highly of the weight of weight descending lifeline to fix, then can between rotating shaft 3 and crank 4, add a single direction ratchet 13.In that weight is slow when falling, take off wind, rotating shaft drives crank by single direction ratchet and rotates, and realizes retarded acting.When wanting the rolling lifting rope, wind is inserted rotating shaft, shake rotating shaft with handwheel, this moment, single direction ratchet made crank and piston motionless.
As shown in Figure 5, the cam (or eccentric wheel) 15 that lifting rope reel 2 drives when rotating in rotating shaft 3 and the rotating shaft rotates, cam (or eccentric wheel) 15 compressing pistons 7 move in cylinder barrel 8, liquid in the cylinder barrel 8 flows to another cylinder barrel 8 by fluid passage 16 by fluid passage magnitude regulator 17, piston 7 in another cylinder barrel 8 is outwards moved, thereby piston 7 is reciprocating 8 li of cylinder barrels.When piston 7 moves in cylinder barrel 8, the liquid that piston 7 compressing cylinder barrels are 8 li flows out it outside cylinder barrel 8, because the throttling action of fluid passage magnitude regulator 17, liquid in the cylinder barrel 8 can not successfully flow out cylinder barrel 8, therefore in cylinder barrel 8, set up hydraulic pressure, this hydraulic coupling plays a part to hinder piston 7 moves in cylinder barrel 8, that is to say that playing a part to hinder weight moves downward.Regulate the speed that liquid channel sized regulating control 17 can change weight descending speed in the weight descending lifeline.
As shown in Figure 6, cam (or eccentric wheel) 15 drives 19 motions of piston guide frame, but because piston guide frame 19 is in contact with one another and relative motion with connecting rod 5, and connecting rod 5 links to each other with piston 7, piston guide frame 19 makes piston 7 reciprocating 8 li of cylinder barrels by connecting rod 5.When piston moves in cylinder barrel, gas in the piston compressing cylinder barrel flows out it outside cylinder barrel, because the throttling action of throttling pore 20, gas in the cylinder barrel can not successfully flow out cylinder barrel, therefore in cylinder barrel, set up a pressure, this pressure plays a part to hinder piston and moves in cylinder barrel, that is to say that playing a part to hinder weight moves downward.When piston moves outside cylinder barrel, same throttling action owing to the throttling pore, gas can not successfully flow into cylinder barrel, therefore forms vacuum in cylinder barrel, this vacuum power plays a part to hinder piston and moves outside cylinder barrel, that is to say that playing a part to hinder weight moves downward.The size of regulating the throttling pore can change the speed of weight descending speed in the weight descending lifeline.
As illustrated in Figures 5 and 6, for solving the speed of piston in crank motion this problem of bigger cyclical variation is arranged, in actual product, can adopt many cover crank connecting rods and piston mechanism or cam (or eccentric wheel) and many piston mechanisms, and make the uniform way of each crank connecting link and piston mechanism or cam (or eccentric wheel) and many piston mechanisms solve unstable this problem of descending speed of weight, the quantity of crank piston is many more, can obtain bigger and more stable resistance more, the descending speed of weight is just even more.
As shown in Figure 7, set pore 9 of the present utility model can be positioned on the piston 7.
As shown in Figure 8, a crank 4 of the present utility model can be connected with a plurality of pistons 7.
