Description

[Detailed description of the invention] Industrial applications FIELD OF THE INVENTION The present invention relates to a wind turbine.

Conventional configuration and its problems In a general winch device, when winding a wire rope onto the winch drum, the free 1-angle is ±2'',
If the angle exceeds ±3° at most, it will be difficult to wind in orderly rows or in multiple layers.

Therefore, in the conventional winch device, a feed screw 2 is rotated in synchronization with the winch drum 1, as shown in FIG. By providing this, the wire loaf ' 4 'i +T can be wound or unwound in multiple layers in an orderly manner.

However, in such a conventional configuration, the wire rope 4
When the feed screw 2 reaches the end of the winch drum 1, the feed screw 2 must be reversed to reverse the direction of movement of the feed base 3, and there is a problem in that the reversing mechanism for this requires a large number of loops.

OBJECT OF THE INVENTION Therefore, the object of the present invention is to enable uniform winding of a tube having a structure C and A70 in a cylinder that does not require a reversing mechanism or the like.
1 target.

Structure of the Invention In order to achieve the above object, the present invention provides the following features. a rotating arm that is interlocked with the winch drum and configured to be movable in the radial direction of the swing with respect to the winch drum; This includes a constant velocity cam groove that makes the speed component of the drum axis direction of the 1-ra constant; a fork that engages with the 1-ra and moves backward in the drum axial direction; Reciprocating movement FJ+ in the direction of the drum axis in conjunction with the fork
and a wire guide that engages with the wire rope near the winch drum and guides the wire rope.

Therefore, due to the effects of the rotating arm and constant velocity cam groove,
Since the wire A7 is reciprocated in the direction of the drum axis in synchronization with the rotation of the 1-inch drum, the wire rope can be wound accurately.Moreover, due to the action of the constant velocity cam groove, the wire rope can be easily swung. Since the wire guide can be moved backwards and forwards simply by turning the arm in one direction, it is possible to eliminate the need for reverse rotation, etc., as in the prior art, and the device can be made smaller and simpler.

DESCRIPTION OF EMBODIMENTS FIG. 1 shows an embodiment of the present invention 01J, in which reference numeral 11 is a winch drum supported by a pair of brackets 12, and is capable of winding and letting out a wire rope 13. 14 is a hydraulic motor that drives the winch drum 11, which has a tooth width 15 fixed to the hydraulic motor 14, an idle tooth width 16 that meshes with the gear 15, and another h-wheel that rotates integrally with the idle gear 16. The configuration is such that power is transmitted to the winch drum 11 to which the tooth width 18 is fixed via the gear 17 and the gear 18 that meshes with the free rotation tooth width 17.

Further, the hydraulic motor 14 is rotatable in both forward and reverse directions,
As a result, the wire rope 13 is taken off and let out.

A square gear 19 is meshed with the free rotating gear 1G, and this gear 1
9 is fixed, and the shaft 20 is passed between both brackets 12.
A arm 21 is fixed to. 22 is a worm wheel that meshes with the worm 21, and this worm wheel 22 is fixed by a bearing bracket 60 and attached to the shaft 2.
3, the worm wheel 22 rotates by 1゛I' in a plane parallel to the axial direction of the winch drum 11.
An rlE rotation arm 24 is attached. Therefore, (mountain J+) the -tor 14 will drive both the winch drum 11 and the rotating arm 1124, etc.
An interlocking device 25 between the winch drum 11 and the swing arm 24 is constructed. When < C1, fLJ rotates, the swing arm 2
Is 4 moving in the direction of one drum axis? The main structure is such that the winch drum 11 rotates half a turn from the winch drum 11 to the other drum axial position. Let d be the wire rope 13 across the entire width W of the winch drum 11.
Required rotation speed N of the winch drum 11 to finish winding
becomes N=W/d. Since it is sufficient for the swing arm 24 to rotate 1/2 while the winch drum 11 rotates N times, the total reduction ratio n in the interlocking device 25 is n=d/2W. Therefore, if the number of teeth of the gear 18 on the side of the wing F"fym 11 is 71, and the number of teeth of the gear 19 on the side of the shaft 20 is 72, the worm reduction ratio n1 becomes rlW = d/2WX l+ / Z2.

The sleeve 26 is attached to the pivot arm 24, for example, at t--1+.
Like the 1M case, rotation is suppressed and only IS movement is free.
Fit U to J3, put on this sleeve 2C, L r-J
28 is a constant velocity cam groove that engages with the bracket 27, and is stepped along the bottom plate 29 passed between both brackets 12. The shape of this constant velocity cam groove 28 is determined so that the speed component of the drum axis direction of the roller 27 based on the rotation of the rotary arm 24 is constant.
As shown in the figure, when the roller 27 rotates around the shaft 23 at a constant angular speed due to the rotation of the rotating member 24, it is assumed that the roller 27 moves at a constant speed in the drum axis direction X. The shape of the constant velocity cam groove 28 can be determined by drawing. 30 is an auxiliary line indicating constant angular velocity displacement; 31
is an auxiliary line indicating the displacement of the sump speed.

As shown in FIG. 1, a fork 32 is engaged with the lug 27. This foot 32 is connected to a pair of guides extending between the brackets 12 in the direction of the ram axis. bar 33

A stand 35 is fixed to one sleeve 34, and this stand 35 has a position C wire loaf 13 opposite to the winch drum 11. An engaging wire guide 36 is attached to the wire guide 364.t and a pair of traversal rollers 37 sandwiching the wire [1-113 therebetween.

In such a configuration, when the oil 1f motor 14 is rotated, the winch drum 11 is thereby rotated and the wire rope 13 is wound up. At this time, the swing arm 24 rotates in conjunction with the winch drum 11, and the roller 27 is guided by the constant velocity cam groove 28, so that the speed component in the axial direction of the driver 11 in A becomes constant. The lie A1 guide 3G is reciprocated at a constant speed in the direction of the drum axis via the engaging fork 32, and as a result, the wire rope 13 is wound neatly around the winch drum 11 one by one. This results in
Wrong winding and round winding of the wire loaf 13 are prevented, and winch troubles are prevented. Furthermore, by winding the wire rope 13 in a compact manner, the space required around the winch drum 11 can be reduced. Moreover, it is also possible to reduce fluctuations in the winding torque. In addition, in Section 1, "uniform velocity" means the winch drum 11
This means that the feed is increased to the wire guide 36 with a constant bit in synchronization with the EO1 rotation of Naturally, the feed speed of the wire guide 36 also changes accordingly.
