Embodiment
Below in conjunction with accompanying drawing, to above-mentioned being clearly and completely described with other technical characteristic and advantage of the utility model, obviously, described embodiment is only section Example of the present utility model, instead of whole embodiment.
Refer to shown in Fig. 1, helicopter unwrapping wire high speed tensioner of the present utility model, comprises frame 10, straining pulley assembly 20, rope sheave 30 and rope sheave support 40.Straining pulley assembly 20 is arranged in frame 10, and rope sheave 30 is connected by sheave shaft 32 with rope sheave support 40, and rope sheave support 40 can be connected in relative rotation with frame 10, and rope sheave support 40 and frame 10 form integral structure.Rope sheave 30 can rotate by wiring wheel shaft 32; Rope sheave support 40 is connected in frame 10 by the rotating shaft 42 of horizontal arrangement, and rope sheave support 40 can rotate around rotating shaft 42.
Refer to shown in Fig. 2, the guide rope 90 pile warp straining pulley assembly 20 of coiling on rope sheave 30, the free end of guide rope 90 is connected with extraneous helicopter.By rope sheave support 40, rope sheave 30 is assembled in frame 10, makes more compact structure, be conducive to line construction; And by realizing moving up and down of rope sheave 30 with being rotationally connected of rotating shaft 42, thus change rope sheave 30, do not need, by crane auxiliary handling rope sheave 30, to meet the needs that helicopter only can hover in finite time.Shown in Fig. 3, by the number of teeth that changes straining pulley assembly 20 gear wheel of tensioner and the number of teeth of pinion be engaged with, choose the speed ratio of rational decelerator 130, ensure that the rotating speed of decelerator 130 and the rotating speed of hydraulic pump are all no more than maximum speed; The unfolding speed per hour of steel guide rope is up to 15km, helicopter can be adapted to and lead cruising speed requirement when putting steel guide rope, with the rope sheave 30 of prior art compared with the split-type structural of frame 10, the fast requirement of helicopter payingoff speed can be adapted to and do not affect the replacing of rope sheave 30, improve efficiency of construction.
The utility model has two kinds of mode of operations: tension force mode of operation and reverse drag mode of operation.Wherein, the process of tension force mode of operation is: guide rope 90 is drawn by helicopter unwrapping wire high speed tensioner, form drag torque, drag torque reaches pinion by the gear wheel on straining pulley assembly 20, the low speed end of decelerator 130 is reached again by pinion, export high-speed electric expreess locomotive 120 to by the speed end of reductor 130, the outlet pressure of high-speed electric expreess locomotive 120 determines the moment of resistance needed when guide rope 90 is braked.Now by rope sheave motor 140, rope sheave 30 is rotated and realize unwrapping wire.
Wherein, the process of reverse drag mode of operation is: engine 110 starts, driven gear pump work, the high pressure liquid force feed that gear pump is discharged drives high-speed electric expreess locomotive 120 to work, the moment that high-speed electric expreess locomotive 120 produces is passed to pinion through reductor 130, pinion drives gear wheel transmission, drives straining pulley assembly 20 to produce tractive effort, and traction guide rope 90 is wound up on rope sheave 30.Now rope sheave 30 reverse rotation is made to realize spiral by rope sheave motor 140.
Helicopter unwrapping wire high speed tensioner is pulling type structure, adopts closed hydraulic circuit system, can pass through overflow valve hydraulic control delivery side of pump pressure, thus adjustment of tonicity size easily.Decelerator 130 is planetary reduction gear.Adopt high-speed electric expreess locomotive 120 can improve the unfolding speed of straining pulley assembly 20, to adapt to the high-speed requirement of helicopter.
Further, frame 10 is arranged a lifting body 50, lifting body 50 comprises driving cylinder and expansion link.Driving cylinder is fixedly connected with frame 10; One end of expansion link is placed in driving cylinder, and the other end of expansion link can stretch out driving cylinder and be resisted against on rope sheave support 40, and expansion link can stretch out along the axis of driving cylinder or bounce back, and drives rope sheave support 40 to rotate around rotating shaft 42 by the stretching motion of expansion link.
Further, lifting body 50 also comprises push rod 60, and the two ends of push rod 60 are resisted against on frame 10 and rope sheave support 40 respectively, and expansion link keeps extension elongation by push rod 60.When needing to change rope sheave 30, driving cylinder is started working, expansion link stretches out a little, promote rope sheave support 40 to rotate around rotating shaft 42, rope sheave support 40 drives rope sheave 30 to rise certain height a little, and by manually push rod 60 being removed, then driving cylinder is return, the rope sheave 30 making rope sheave support 40 and it is installed falls to minimum point by own wt, starts to change rope sheave 30.After completing replacing, driving cylinder is started working again, and expansion link stretches out, and by manually push rod 60 being in place, driving cylinder quits work.
As the enforceable mode of one, lifting body 50 is hydraulic jack, and expansion link can reliably stop at arbitrary extension elongation, by operation jack expansion link is stretched out or bounce back, thus make against rope sheave support 40 by rotation realization move up and down.Use push rod 60 can effective locking rope sheave 30 position of lifting, avoid the impact owing to producing in the excessive gravity of rope sheave 30 or work progress, cause rope sheave 30 to fall, affect and normally work.
Further, refer to shown in Fig. 3, cable inlet bracket 70 is set between rope sheave 30 and straining pulley assembly 20; Cable inlet bracket 70 is arranged in the first limit assembly 80, first limit assembly 80 for limiting guide rope 90 trend the rope passage excessively that there is guide rope 90 and pass.
Further, cable inlet bracket 70 can move horizontally along the axis of sheave shaft 32.The cable inlet bracket of continuous movement, can make the guide rope 90 in reverse drag mode of operation be wound on equably on rope sheave 30 along the axis of rope sheave 30, improve spiral quality.
As the enforceable mode of one, second limit assembly and the 3rd limit assembly are set respectively between cable inlet bracket 70 and straining pulley assembly 20, between straining pulley assembly 20 and helicopter, all there is in second limit assembly and in the 3rd limit assembly the rope passage excessively that guide rope 90 passes, second limit assembly is fixedly connected with frame 10 respectively with the 3rd limit assembly, be equivalent to all carry out spacing in the end of incoming cables of straining pulley assembly 20 and leading-out terminal, effectively define the guide rope 90 of winding on straining pulley assembly 20, avoid occurring wrapping phenomena in spiral process or unwrapping wire process.
As the enforceable mode of one, the first limit assembly 80, second limit assembly and the 3rd limit assembly include transverse roller and two vertically arranged vertical rollers of at least one horizontal arrangement.Two vertical rollers transversely roller axially and interval arrange, transverse roller and vertical roller surrounded rope passage, and two vertical rollers lay respectively at the both sides of guide rope 90.More preferably, the first limit assembly 80 arranges two horizontal roller, two horizontal roller vertically roller axially and interval arrange, the coffin that two horizontal roller and two vertical rollers surround can carry out spacing to guide rope 90 from four direction.As the enforceable mode of another kind, the first limit assembly 80, second limit assembly and the 3rd limit assembly can be all an annulus.
Above-described specific embodiment; further detailed description has been carried out to the purpose of this utility model, technical scheme and beneficial effect; should be appreciated that and the foregoing is only specific embodiment of the utility model, and be not used in restriction protection range of the present utility model.Particularly point out, to those skilled in the art, all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
