Description

Slider stabilizing device for splitting conductor strand blocks and stranding equipment Technical Field The utility model relates to the technical field of stranded wires, in particular to a pull head stabilizing device for dividing conductor strand blocks and stranded wire equipment. Background With the development of power transmission towards large capacity, large-section conductors are increasingly applied, but due to the existence of an alternating current skin effect, when the diameter of the conductor is increased to a certain degree, the alternating current resistance of the conductor is obviously larger than the direct current resistance of the conductor, so that the practicability and the economy are lost by increasing the sectional area. To effectively reduce the ac resistance of the conductor, a split conductor structure may be employed. The split conductor is formed by twisting a plurality of fan-shaped strand blocks, and can reduce the skin effect between wires, thereby reducing the conductor alternating current resistance and improving the current-carrying capacity of the cable. When manufacturing the split conductor, split conductor strand blocks are manufactured on a stranding machine first, and then each split conductor strand block is assembled on a cabling machine. The split conductor comprises a plurality of layers of wires which are sequentially arranged from inside to outside, when the split conductor strand blocks are manufactured, the pull head is firstly manufactured, namely, the first segment of split conductor strand blocks are manufactured, in the process of the pull head, the production line stops and moves, the twisting pitch is difficult to reach the process requirement, and therefore the segment of split conductor strand blocks of the pull head cannot flow into the next working procedure. When the pull head is pulled, the wire ends of the wires pass through the plurality of twisting cages and then are connected to traction equipment, then, the traction equipment pulls the wires to advance, each twisting cage is opened in sequence along the advancing direction of the wires, each twisting cage comprises a twisting mechanism and a pressing wheel device, each twisting mechanism is used for twisting one layer of wires, the twisting mechanism is used for twisting the wires, simultaneously, the twisting mechanism is used for pressing twisted wire bundles formed by twisting through the pressing wheel device, the pressing wheel device comprises two pressing wheels which are equivalent to a group of dies, and the cross section of the twisted wire bundles is pressed into a fan shape. Because the twisting cage can drive the twisting wire harness to rotate when twisting the conductor, the fan-shaped twisting wire harness rotates and passes between two pinch rollers of the next twisting cage, the posture is always changing because the fan-shaped twisting wire harness is always rotating, and the posture is difficult to match with the shapes of the two passing pinch rollers, so that an operator needs to start up until the posture of the fan-shaped twisting wire harness is matched with the shapes of the two passing pinch rollers, and can control the subsequent pinch rollers to compress the fan-shaped twisting wire harness, a large amount of copper materials are scrapped, and a 2500mm2 split strand block is taken as an example, and a product is scrapped by about 120 meters when the split strand block in the prior art is pulled.
