Description

Technical Field

[0001] The invention relates to the technical field of cable cabling, in particular to a fan-shaped insulated core cabling anti-turnover device. Background Art

[0002] The composition of large-section low-voltage cables generally adopts a 4+1 or 3+1 core combination. The conductive core adopts a fan-shaped structure, which has many advantages over the traditional round core. The fan-shaped core with the same cross-section has a smaller total cross-sectional area after being cabled, saving filling materials. At the same time, the wrapping tape, armor material and sheath material can be greatly saved, reducing product costs. The smaller cross-sectional area of ​​the finished cable can also be more convenient in transportation and cable installation.

[0003] During the cabling process, the core is twisted and moved forward while rotating. The rotation must be synchronized with the cabling twisting to ensure that the sharp corners of the fan-shaped core are always aligned with the center of the cabling circle to ensure the roundness of the cabling. Due to the long distance between the core reel, the distribution reel and the axis of the twisting cage, the pre-twist angle is difficult to control. During the cabling process, the fan-shaped core is easy to turn over, which will not only reduce the diameter of the cable core, but also damage the cable and affect the appearance of the cable. Therefore, during the cabling process, the angle of each fan-shaped core must be paid attention to in real time. In order to prevent the core from turning over, the fan-shaped core needs to be pre-twisted frequently, which is inconvenient to operate and affects production efficiency.

[0004] Authorization announcement number CN203480936U, authorization announcement date 2014.03.12 discloses a fan-shaped and tile-shaped cable core crimping device, including a bracket, a pressure wheel and a supporting wheel, the bracket is composed of a sleeve and a bracket plate, the circumferential surface of the pressure wheel is provided with an arc groove along the circumferential direction, the circumferential surface of the supporting wheel is provided with an angular groove along the circumferential direction, the pressure wheel and the supporting wheel are respectively mounted on two mounting shafts, rotate relative to the mounting shafts, and are mounted on the bracket plate through the mounting shafts, so that the pressure wheel and the supporting wheel are opposite to each other in a direction perpendicular to the axis of the sleeve, and are located on both sides of the axis of the sleeve. The wire core crimping device has the following defects: (1) The distance between the crimping wheel and the supporting wheel is fixed and cannot be adjusted. It is only applicable to fan-shaped wire cores of one radius and has poor versatility. (2) During the cabling process, it is still necessary to pay real-time attention to the angle of each fan-shaped wire core and frequently pre-twist the fan-shaped wire cores, which is inconvenient to operate and affects production efficiency. (3) The device cannot pre-twist the fan-shaped wire cores. The torsional stress generated when the fan-shaped wire cores are twisted will cause the insulation of the fan-shaped wire cores to deform due to excessive stress, and the insulation will be crushed by the crimping wheel when entering the crimping wheel.

In the present invention, the pressure wheel device is fixed on the distribution disk to ensure the synchronous rotation of the pressure wheel device and the distribution disk; the angle of the fan-shaped wire core is fixed by the cooperation of the wire core arc wheel and the wire core angle wheel, so as to ensure that the relative angle of the fan-shaped wire core entering the stranding cage axis core remains unchanged, and the fan-shaped sharp corner always points to the axis during torsion, thereby ensuring that the fan-shaped wire core does not turn over; the left side plate and the right side plate are parallel to each other and inclined on the distribution disk, so that the pressure wheel device forms a cross-section with a certain angle to flip sideways (the specific flipping angle depends on the actual situation, and the angle between 10° and 45° can be selected), so that the fan-shaped wire core has a certain pre-twist angle, which can not only evenly distribute the stranding stress, but also avoid the fan-shaped core wire stress Too large will cause the insulation to twist and deform, thereby reducing the compression damage of the sector-shaped core wire insulation; the arc-shaped oblong hole is concentric with the threading hole, and the pressure wheel device can be rotated or fixed along the arc-shaped oblong hole with the center of the threading hole as the axis through the tightness of the bolt, so as to be able to adjust the angle of the core arc wheel and the core angle wheel on the distribution plate, thereby ensuring that the sector-shaped core is always in the center position between the core arc wheel and the core angle wheel (that is, the cable core is always located between the core arc wheel and the core angle wheel without deviation), and the cable core will not be excessively squeezed when entering the axis of the stranding cage, effectively avoiding the compression damage of the sector-shaped core wire insulation; the core angle wheel and the core arc wheel are made of nylon rubber material, which has a certain rigidity and elasticity, and the pressure generated.

By tightening the bolts, the pressure wheel device can rotate or be fixed along the arc-shaped oblong holes with the center of the threading hole as the axis, so as to adjust the angles of the core arc wheel and the core angle wheel on the distribution plate, thereby ensuring that the fan-shaped core is always in the right position between the core arc wheel and the core angle wheel (that is, the cable core is always located in the middle position between the core arc wheel and the core angle wheel without deviation). When the cable core enters the axis of the cage, it will not be excessively squeezed, effectively avoiding the compression of the fan-shaped core wire insulation;

[0021] (4) The adjusting screw can be rotated by the handle to move the adjusting screw forward or backward, so that the wire core arc wheel bracket slides inward or outward in a straight line between the left plate and the right plate, thereby adjusting the position of the wire core arc wheel and changing the gap (distance) between the wire core angle wheel and the wire core arc wheel. This makes the present invention applicable to fan-shaped wire cores of different radii and allows the fan-shaped wire core to be in a more natural position (with a suitable clamping force) without being squeezed too much.
