Abstract
The invention discloses one kind friction two-fold cylinder, and positive role is served by the perfect and raising that two-fold cylinder angle compensation is A＆R hoister systems friction two-fold cylinder.Its technical scheme is：Friction two-fold cylinder includes two reels, each reel includes spool body, gear wheel and grooving, make steel wire rope when alternately winding, the steel wire rope come out from reel is capable of the rope inlet of just another reel of adjusting to a line so that steel wire rope can stable, the seamless alternating winding of straight line between two reels.
Description
Technical field
The present invention relates to the frictional two-fold cylinder on the pulling winch applied to deep water pipe laying barge A＆R hoister systems, especially
It is related to so that energy straight line steadily replaces the friction two-fold cylinder of lay winding wire ropes between two reels.
Background technology
Deep water pipe laying barge A＆R (releasing winch is Abandonment＆Recovery Winch) hoister system product is external
Producer is monopolized, and friction two-fold cylinder is applied on the pulling winch of deep water pipe laying barge A＆R hoister systems.The characteristics of pulling winch is steel
Cord import pulling force super large, pulling winch absorb most steel wire rope tension by frictional two-fold cylinder, steel wire rope is existed
Super large amplitude pulling force between pulling winch inlet and outlet reduces.And the related core technology of two-fold cylinder that rubs has clamped down on Chinese A＆R
The development of hoister system, steel wire rope how between two reels can straight line smoothly replace winding be a problem.
The content of the invention
The brief overview of one or more aspects given below is to provide to the basic comprehension in terms of these.This general introduction is not
The extensive overview of all aspects contemplated, and the key or decisive key element for being both not intended to identify all aspects is also non-
Attempt to define the scope in terms of any or all.Its unique purpose is to provide the one of one or more aspects in simplified form
A little concepts think the sequence of more detailed description given later.
It is an object of the invention to solve the above problems, there is provided one kind friction two-fold cylinder, pass through two-fold cylinder angle compensation
Perfect and raising for A＆R hoister systems friction two-fold cylinder serves positive role.
The technical scheme is that：Rubbed two-fold cylinder present invention is disclosed one kind, including the first reel, the second reel,
Wherein the first reel includes the first spool body, the first gear wheel and the first grooving, and the second reel includes the second spool body, second largest
Gear and the second grooving, steel wire rope are alternately wound between the first reel and the second reel, the steel come out from the grooving of a reel
The grooving of another reel of cord adjusting to a line enters position of restricting.
According to an embodiment of the friction two-fold cylinder of the present invention, the first spool body grooving pitch and the second spool body grooving section
Away from being b, first grooving center of the first spool body to the distance of the first gear wheel is a, first rope of the second spool body
The distance of groove center to the second gear wheel is c, the diameter at the first reel steel wire ropes center and the second reel steel wire ropes center it is straight
Footpath is e, wherein c-a=b/2.
According to an embodiment of the friction two-fold cylinder of the present invention, the first reel is horizontal positioned, the second reel slant setting, the
The angle of one reel and the second reel is α, wherein α=arc tan (b/e).
Present invention contrast prior art has following beneficial effect：The friction two-fold cylinder of the present invention includes two reels, often
Individual reel includes spool body, gear wheel and grooving, and making steel wire rope, the steel wire rope come out from a reel can when alternately winding
The just rope inlet of another reel of adjusting to a line so that steel wire rope can stable, the seamless friendship of straight line between two reels
For winding.
Brief description of the drawings
After the detailed description of embodiment of the disclosure is read in conjunction with the following drawings, it better understood when the present invention's
Features described above and advantage.In the accompanying drawings, each component is not necessarily drawn to scale, and has similar correlation properties or feature
Component may have same or like reference.
Figure 1A to 1C shows the structural representation of first reel.
Fig. 2A to 2C shows the structural representation of second reel.
Fig. 3 A to 3F show the structural representation of the embodiment of the friction two-fold cylinder of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Pay attention to, it is below in conjunction with accompanying drawing and specifically real
It is only exemplary to apply the aspects of example description, and is understood not to carry out any restrictions to protection scope of the present invention.
As shown in Figure 3A, friction two-fold cylinder of the invention includes the first reel 5 and the second reel 6.The structure of first reel 5
As shown in Figure 1A to 1C, including spool body 52, gear wheel 51 and grooving 53.The structure of second reel 6 is as shown in Fig. 2A to 2C, bag
Include spool body 64, gear wheel 61 and grooving 63.B in Figure 1A and Fig. 2A is spool body grooving pitch, and a is spool body 52 first
To the distance at the center of gear wheel 51, c is 64 first grooving centers of spool body to the distance at the center of gear wheel 61, e at grooving center
For the diameter at steel wire rope center on reel.
Respectively there are 7 independent straight groovings 53,63 on two reels 5 and 6 of friction two-fold cylinder, they are except the position of grooving
Have any different outer, all, c and a difference are 1/2 b, i.e. c-a=b/2 to other parameters.Friction two-fold cylinder answering on winch
With Fig. 3 A are seen, Fig. 3 B are shown in the two-fold cylinder work extracted.
As shown in Fig. 3 C to Fig. 3 E, the first reel 5 is horizontal positioned, and the angle between the second reel 6 and the first reel 5 has individual
Angle α, α=arc tan (b/e), this angle can make the steel wire rope below first straight grooving out on first volume cylinder 5
Can straight line smoothly into first grooving of the second reel 6, steel wire rope wound on the grooving of the second reel 6 after half-turn again from
Come out straight line above first grooving of spool body 64 smoothly to enter in second grooving of spool body 52, steel wire rope is first
Straight line is come out smoothly into the second reel 6 from second grooving of the first reel 5 again after half-turn is wound on the grooving of reel 5
In second grooving, so repeatedly, directly come out after reaching last grooving of spool body 64, movement locus is shown in Fig. 3 F
It is shown.This angle compensation technology makes steel wire rope replace perfect transition when winding between two-fold cylinder, very naturally, steadily.First
It is two reel same plane views and two reels respectively with oblique shown in the combined effect as Fig. 3 C of the reel 6 of reel 5 and second
View.
Offer is for so that any person skilled in the art all can make or use this public affairs to being previously described for the disclosure
