For reference, in the drawings for supporting an embodiment of the present invention, two unscrewed rotating pipes 200 are shown as an example, but this is only one example, and is not limited thereto. It can be two or more, i.e. three or four.

Here, the support 110 may be composed of a horizontal stand 120 installed in a horizontal direction with respect to the floor surface, and a vertical stand 130 installed in a vertical direction by a predetermined height from one side of the horizontal stand 120. Thereby, the support 110 may be configured in a substantially b-shape.

A driving wheel 122 may be installed at the bottom of each corner side of the horizontal platform 120 in the supporting unit 110 to facilitate movement with respect to the floor surface, and one side of the vertical platform 130 protrudes upward. An approximately U-shaped handle portion 132 may be installed.

Therefore, when the operator pushes or pulls the supporting portion 110 to a desired position in a state where the handle portion 132 is gripped, the driving wheels 122 installed at the corner side of the horizontal band 120 of the supporting portion 110 are lowered. It can be easily moved by driving.

The driving unit 150 is installed on the horizontal base 120 of the base 110, and the unwinding rotation tube 200 is rotated at one end of which is rotatably installed on the vertical base 130 of the base 110. It may be installed to be supported with respect to the plate 140.

At this time, one end of the unwinding rotating tube 200 is installed to be supported while passing through the rotating plate, so that the inlet hole 210 formed at the end of one end of the unwinding rotating tube 200 has a vertical base 130. The state exposed to the back is achieved.

On the other hand, the driving shaft of the drive unit 150 and the circumferential surface of the rotating plate 140 are connected by a power transmission means such as a chain 154, so that the rotating plate 140 rotates in conjunction with driving of the driving unit 150. By being made, at least two or more loosening rotating pipes 200 are rotated by rotation of the rotating plate 140.

For reference, in the exemplary embodiment of the present invention, the driving shaft of the driving unit 150 and the rotating plate 140 are connected by a chain 154 as an example, but this is only an example, and is not limited thereto. Needless to say, various conventional power transmission means such as belts and gears may be applied.

The process of releasing the strand 20 of the wire rope 10 using the device 100 for automatically releasing the strand of the wire rope that can be configured as described above will be described as follows.

First, the strands 20 constituting several strands at one end of the wire rope 10 are to be spread with strands corresponding to the number of unwinding rotating tubes 200.

For example, when there are two unwinding rotating tubes 200, the end portions of the wire rope 10 are opened so that a plurality of strands 20 are opened into two strands, and then each strand is unwinding rotating tube 200 ) Is inserted into each inlet hole 210, and the operator presses the foot switch 152 so that the driving unit 150 is driven.

As the rotation plate 140 is rotated in conjunction with the driving of the driving unit 150, the rotation unwinding rotation pipes 200 fixed to one end of the rotation plate 140 are also interlocked to rotate. At this time, at this time, the operator may push the wire rope 10 to loosen the strand 20 gradually toward the inlet hole 210 of the loosening rotating pipes 200.

Here, the plurality of strands 20 constituting the wire rope 10 are wound in one direction, such as a spiral shape, to form a twisted state, and the rotating plate 140 is opposite to the twist direction of the strands constituting the plurality 20 It is desirable to make the rotation in the direction.

Therefore, the strands 20 of the wire rope 10 are separated into strands corresponding to the number of unwinding rotating tubes 200 in each inlet hole 210 of the unwinding rotating tube 200, which is rotated in a direction opposite to the twisting direction. When each strand 20 of one wire rope 10 is inserted and the operator pushes a little, the strand 20 of each strand is automatically pulled through each loosening rotating tube 200 that is rotated in the opposite direction of the twist direction. While being discharged through the outlet hole 220 is separated.

At this time, if the length of the loosening rotating tube 200 is short, there is a possibility that the strands 20 discharged through each outlet hole 220 may be entangled again, so that the loosening rotating tube 200 is applied with a long length. In this case, when the length of the unwinding rotating tube 200 is long, the other side on which the outlet hole 220 is located has no separate support means, so it is difficult to maintain the horizontal state, and thus a separate support member 300 It is provided with a long unwinding rotating tube 200 can be rotated in a state that maintains a horizontal state.

Figure 6 is a perspective view showing a variable support provided to the device for automatically releasing the strand of the wire rope according to an embodiment of the present invention, Figure 7 is a wire rope strand in the state provided with the support member of Figure 6 automatically As a perspective view of a use state showing a released state, as shown in FIGS. 6 and 7, the support member 300 includes a lower support 310 supported in an upright state with respect to a floor surface, and this lower support It may be composed of an upper support 320 supported in an upright state on the upper side of (310).

Here, the support hole 340 is formed in a diameter for the unwinding rotating tube 200 to pass through, and may be formed in a number corresponding to the number of the unwinding rotating tube 200.

For example, when there are two loosening rotating tubes 200, two supporting holes 340 may also be applied, and when three loosening rotating tubes 200 are three, three supporting holes 340 may also be applied. .

Therefore, as shown in FIG. 7, when the loosening rotating tube 200 is disposed in a state passing through the support hole 340 of the support member 300, the intermediate end of the loosening rotating tube 200 having a predetermined length Or by being supported by the other end adjacent to the outlet hole 220, it is stably supported in a horizontal state.

That is, as described above, one end of the loosening rotating tube 200 is supported in a state that penetrates the rotating plate 140 installed on the vertical stand 130 of the supporting part 110, and the middle end or the other side is provided. The end is passed through the support hole 340 formed in the rotating plate 330 of the support member 300 to be supported, so that the loosening rotating tube 200 having a predetermined length is stably supported in a horizontal state Will be done.

As described above, in a state in which the unwinding rotating tube 300 having a predetermined length is horizontal and stably supported, when a driving signal is applied to the driving unit 150, the rotating plate 140 of the supporting unit 110 rotates. As at least two or more loosening rotating tubes 200 are rotated, at this time, the rotating plate 330 of the supporting member 300 is also rotated by the rotating rotating tubes 200, and the upper portion of the supporting member 300 is rotated. As the free rotation is performed with respect to the support 320, rotation is simultaneously performed.

Therefore, the strands 20 of the separated strands flowing through each inlet hole 210 of each unwinding rotating tube 200 are continuously rotated in the direction opposite to the twisting direction by the rotating unwinding rotating tube 200. Accordingly, the discharge is made through each outlet hole 220 as a loose state.

For reference, in the exemplary embodiment of the present invention, as an example, two unwinding rotating pipes 200 are provided, and in the case of the wire rope 10 in which the seven strands 20 are twisted, three and four strands are bundled. It can be separated into (20), in this case, the three bundles of strands 20 can be released into one and two bundles of strands 20, and the two bundles of strands 20 are each one strand again. (20).

In addition, since one strand 20 forms a twisted form of a plurality of strands 30 again, after separating the plurality of strands 30 from the ends of one strand 20 into two bundles again, the present invention By performing the operation as described above using the device 100 according to the embodiment it is possible to release each of the individual wires (30).

Therefore, according to the apparatus 100 for automatically releasing a strand of a wire rope according to an embodiment of the present invention, a strand 20 formed by twisting several strands of strands 30 and several strands of such strands 20 After being able to automatically and automatically release the wire rope 10 made after twisting, the number of working persons is reduced and the working time is greatly reduced, so that the workability can be greatly improved. .

On the other hand, using the device 100 according to an embodiment of the present invention, as described above, each strand 20 or a single strand 30 in the released state, the undamaged strand 20 or strand ( 30) can be used to regenerate the wire rope 10 of good quality again, or reproduce it with the wire rope 10 having a different number of strands.
