Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
A kind of embodiment as shown in Figure 1, a kind of cable winding experimental facilities, comprises the first winch 1 and the second winch 2, one end of cable 3 is fixed on the first winch 1, for the rotation with the first winch 1, cable 3 is wrapped in to the first winch 1; The other end of cable 3 is fixed on the second winch 2, for the rotation with the second winch 2 by cable winding at the second winch 2.That is to say, the winch here works to be wound around cable, the process of folding and unfolding cable in simulation actual condition, Fig. 1 shows the first winch 1 and 2 pairs, the second winch is stretched a cable, rotation with the first winch 1 or the second winch 2, cable 3 both can be wound on the first winch 1, or was wound on the second winch 2, and this torque of depending on which winch is larger.
The first winch 1 can be identical with the second winch 2, and said identical shape, size, model, performance and the parameter that refers to two winches can be in full accord here, can certainly be inconsistent.
Between the cable outlet direction of the cable outlet direction of the first winch 1 and the second winch 2, angulation is adjustable.Here said angle is adjustable, has comprised that adjustable in short transverse and horizontal direction, the embodiment shown in Fig. 1 are, the two is in the horizontal direction over against becoming 180 degree, and on sustained height.Whether identically on height from Fig. 1 cable, whether tilt to be easy to find out, the angle becoming in horizontal direction can be from equipment vertical view cable whether tilt and find out easily.Certainly a winch therein, for example below the second winch 2, install a rotating disk, the second winch 2 can be rotated on this rotating disk, so just can adjust 1 one-tenth certain level angle of the second winch 2 and the first winch, the experiment situation in the time of can measuring the angled pulling cable of level so and then just; Certainly, a hoisting gear can also be further set below this rotating disk, make this rotating disk become liftable rotating disk, so just can adjust the difference in height of the cable outlet of the first winch 1 and the cable outlet of the second winch 2, and then just can measure occur angled experiment situation while tiltedly dragging cable in short transverse.
The first winch 1 comprises that the first winch driver part 11, the first winch driver parts 11 are connected with the first winch 1, for driving the first winch 1 rotation with folding and unfolding cable.For example, the first winch driver part 11 can adopt oil motor, also can adopt motor.Oil motor or motor are connected with the first winch 1 by shaft coupling, drive the first winch 1 to rotate.
For cable is wrapped on winch uniformly, on each winch, be also provided with cable-remover, the first cable-remover 12 of the first winch 1 of take is below example, provides a kind of preferred structure of cable-remover, as shown in Figure 2:
The first winch 1 also comprises the first cable-remover 12 that is positioned at the first winch cable outlet place, the first cable-remover 12 comprises the first leading screw 121, the first screw 122 and first row cable framework 123, the first leading screw 121 is connected with the first winch driver part 11, for rotation under driving at the first winch driver part 11; The first screw 122 engages with the first leading screw 121; First row cable framework 123 is connected with the first screw 122, and first row cable framework 123 is provided with the through hole that current supply cable passes, for when the first leading screw 121 rotation along the moving axially of the first leading screw 121, so that cable is wrapped on the first winch 1 equably.In figure, also guide rail 124 can be set, its effect is the effect of auxiliary guiding of playing during along the moving axially of the first leading screw 121 at first row cable framework 123.Certainly, as a kind of preferred situation, the first screw 122 can be integral with first row cable framework 123.In general, the first cable-remover 12 is arranged in the first winch cable outlet place, that is to say cable through the first cable-remover 12 then around to the first winch 1.
By this structure, during operation, the first winch driver part 11 drives the first winch 1 to rotate, also drive the rotation of the first leading screw 121 simultaneously, rotation along with the first leading screw 121, the first screw 122 is along the axial translation of the first leading screw 121, and then drive first row cable framework 123 to pass the cable of first row cable framework 123 interior bone along the axial translation of winch rotating shaft, being equivalent to cable 3 is wrapped in the rotating shaft of the first winch 1 on one side, rotating shaft along the first winch 1 on one side moves axially, thereby realized cable 3 uniformly on the first winch 1 by the first cable-remover 12.For the speed of wrap of cable is matched with the translational speed of screw 122, the parameters such as screw-nut can be according to cable winding situation, and for example the specification of the specification of cable and the first winch is carried out parameter adaptation when the design phase of product.
Above-mentioned, the first winch 1 and the first leading screw 121 drive by the first winch driver part 11, and those skilled in the art are also thinkable, and the first leading screw 121 is separately established a first independent leading screw driver part and controlled, for example setting up a motor, is also feasible undoubtedly.If so done, the one, need the driver parts that increase more, the 2nd,, the translational speed of the speed of wrap of cable and screw 122 so generally also just can only form and synchronize cooperation by electrical control.And if the first winch driver part 11 mentioned above drives the situation of the first winch 1 and the first leading screw 121 simultaneously, the parts of middle gear, tooth bar that can be by separately and so on connect, form different drive ratios, just can form mechanically synchronous, be more conducive to the reliable and stable of system operation.
Similarly, more even for cable is wound around on the second winch 2, before the second winch 2, can be provided with the second cable-remover.Equally, its preferred structure can be identical with the first cable-remover, repeats no more here.
