DETAILED DESCRIPTION

[0021] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0022] Embodiment 1: A cable strand untwisting mechanism, comprising: two symmetrically arranged side support plates 2, a plurality of first support frames 3 are arranged between the two side support plates 2 and spaced apart along the circumference thereof, and a wire drum frame 4 is movably installed inside the first support frame 3;

[0023] A connecting ring 805 is coaxially mounted on the outer wall of the first support frame 3 on the rotation axis of the wire drum frame 4, one end of a support plate 806 is fixedly connected to the connecting ring 805, and the other end is fixedly connected to a third support frame 808 with a first limiting hole 6 through a clamping column 807;

[0024] As attached Figure 2 As shown, direction A is the cage twisting direction. When the wire on the wire drum rack is moving, it is passed through the first limiting hole. Then, during the moving process, the positioning and limiting of the first limiting hole enables the wires with different winding heights to pass through the outlet at the same height, which is conducive to the smooth twisting of the wires.

[0025] An arc-shaped slide groove 809 is provided on the first support frame 3 with the axis of the wire drum frame 4 as the center and located at the front and rear sides of the connecting ring 805, respectively. The connecting ring 805 rotates to make the clamping column 807 slide from one arc-shaped slide groove 809 to the inside of another arc-shaped slide groove 809;

[0026] As attached Figure 3As shown, direction B is the detwisting direction, and the stop block is driven upward by contraction of the telescopic rod, and the connecting ring is rotated to make the clamping column rotate from the inside of the arc-shaped slide groove on one side of the wire drum rack to the inside of the arc-shaped slide groove on the other side, which can drive the third support frame to move to the other side of the wire drum rack, thereby converting from direction A to direction B, and the wire on the wire drum rack passes through the first limit hole to achieve detwisting of the wire.

[0027] A stop block 804 is provided downstream of the rotation direction of the support plate 806 and between the two arc-shaped slide grooves 809 to limit the clamping column 807 inside the arc-shaped slide groove 809, and a second support frame 801 is provided above the stop block 804. The second support frame 801 is connected to the stop block 804 through a telescopic rod 803 to drive the stop block 804 to move up and down.

[0028] The stop block 804 includes two stop portions 8041 and a connecting portion 8042 located between the two stop portions 8041 . The connecting portion 8042 is fixedly connected to the movable end of the telescopic rod 803 .

[0030] A plug hole 810 for inserting the stopper 8041 is provided below the stopper block 804 and on the first support frame 3 .

[0031] The connection ring 805 is connected to the outer wall of the first support frame 3 via a bearing 7 , and the connection ring 805 is fixedly sleeved on the outer wall of the bearing 7 .

[0032] The two side support plates 2 are installed together on a shaft body 1 , and the two side support plates 2 are spaced apart along the length direction of the shaft body 1 .

[0033] Embodiment 2: A cable strand untwisting mechanism, comprising: two symmetrically arranged side support plates 2, a plurality of first support frames 3 are arranged between the two side support plates 2 and spaced apart along the circumference thereof, and a wire drum frame 4 is movably installed inside the first support frame 3;

[0034] A connecting ring 805 is coaxially mounted on the outer wall of the first support frame 3 on the rotation axis of the wire drum frame 4, one end of a support plate 806 is fixedly connected to the connecting ring 805, and the other end is fixedly connected to a third support frame 808 with a first limiting hole 6 through a clamping column 807;

[0035] An arc-shaped slide groove 809 is provided on the first support frame 3 with the axis of the wire drum frame 4 as the center and located at the front and rear sides of the connecting ring 805, respectively. The connecting ring 805 rotates to make the clamping column 807 slide from one arc-shaped slide groove 809 to the inside of another arc-shaped slide groove 809;

[0036] The support plate is driven to rotate by the connecting ring, so that the clamping column moves from one arc-shaped slide groove to another arc-shaped slide groove, thereby driving the third support frame to move to the other side. The guiding direction of the wire can be adjusted according to the actual situation, so as to realize the switching of the wire between the traveling cage twisting and the back twisting, thereby expanding the scope of use of the device, and the structure is simple and reliable, and the convenience of personnel operation is also improved.

[0037] A stopper 804 is disposed downstream of the support plate 806 in the direction of rotation and between the two arc-shaped slide grooves 809 to limit the clamping column 807 inside the arc-shaped slide groove 809, and a second support frame 801 is disposed above the stopper 804. The second support frame 801 is connected to the stopper 804 through a telescopic rod 803 to drive the stopper 804 to move up and down;

[0038] After the clamping column is in place, the stop block is driven by the telescopic rod to be inserted into the insertion hole to fix the position of the support plate, thereby preventing the tension during cable transmission from causing the third support frame to move, thereby causing the cables to be tangled and messy.

[0039] The stop block 804 includes two stop portions 8041 and a connecting portion 8042 located between the two stop portions 8041 . The connecting portion 8042 is fixedly connected to the movable end of the telescopic rod 803 .

[0041] A plug hole 810 for inserting the stopper 8041 is provided below the stopper block 804 and on the first support frame 3 .

[0042] The first support frames 3 are distributed at equal intervals.

[0043] The wire drum rack 4 is movably connected to the inside of the first support frame 3 through a connecting seat 5 .

[0044] The working principle is:

[0045] During the movement of the wire on the wire drum rack, the wire is passed through the first limiting hole. During the movement, the positioning and limiting of the first limiting hole enables the wires with different winding heights to pass through the outlet at the same height, which is conducive to the smooth twisting of the wires.

[0046] When the device needs to be detwisted, the stop block is driven upward by contracting the telescopic rod, and the connecting ring is rotated to make the clamping column rotate from the inside of the arc-shaped slide groove on one side of the wire drum rack into the inside of the arc-shaped slide groove on the other side, which can drive the third support frame to move to the other side of the wire drum rack, and the wire on the wire drum rack passes through the first limit hole to achieve detwisting of the wire;

[0047] After the clamping column is in place, the stop block is driven by the telescopic rod to be inserted into the jack to fix the position of the support plate, thereby preventing the tension during the transmission of the wire from causing the third support frame to move, thereby improving the position stability of the third support frame.

[0048] When the above-mentioned cable twisting detwisting mechanism is adopted, it drives the support plate to rotate through the connecting ring, so that the clamping column moves from one arc-shaped slide groove to another arc-shaped slide groove, thereby driving the third support frame to move to the other side. The guiding direction of the wire can be adjusted according to the actual situation, so as to realize the switching of the wire between cage twisting and detwisting, thereby expanding the scope of use of the device, and the structure is simple and reliable, and the convenience of personnel operation is also improved.

[0049] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
