[0002] Patent CN118888222B discloses a production equipment for corrosion-resistant overhead lines, which vertically stacks a frame stranding machine and two electrolyte tanks. Although this can make the ceramic film layer on the surface of the steel core and aluminum conductor grow more evenly, the entire set of equipment is difficult to install, the vertical setting of the frame stranding machine makes feeding inconvenient, and the large height difference between the two electrolyte tanks results in high energy consumption of the circulating water pump. Utility Model Content

[0003] The purpose of this invention is to provide a stranding device for corrosion-resistant overhead lines, which improves the problems of difficult installation, inconvenient material feeding, and high energy consumption of circulating water pumps in existing production equipment without affecting the uniformity of ceramic film growth.

[0004] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:

[0005] A stranding device for corrosion-resistant overhead lines, characterized in that it includes a frame stranding machine, an electrolyte tank 1, and an electrolyte tank 2 arranged sequentially in a horizontal direction. Electrolyte tank 1 and electrolyte tank 2 each contain a horizontally placed cylindrical electrode 1 and a cylindrical electrode 2. The electrolyte tanks contain electrolyte, and the cylindrical electrodes are immersed in the electrolyte. A steel core passes sequentially through the frame stranding machine, electrolyte tank 1, and electrolyte tank 2 in a horizontal direction. The surface of the steel core has a pre-coated insulating film layer. The side walls at both ends of electrolyte tank 1 have stranding discs 1 and 2. The side wall of electrolyte tank 2 near electrolyte tank 1 has a stranding disc 3. The other side wall of electrolyte tank 2 has a wiring hole. The stranding disc has a central hole, and several wire holes are surrounding the central hole. All the central hole, wire holes, and wiring holes are plugged. The steel core passes through the electrolyte tank from the central hole. After being led out from the frame stranding machine, the aluminum wire passes sequentially through the wire holes on stranding reels one, two, and three into electrolyte tank two. The frame stranding machine rotates around the steel core, and each stranding reel rotates synchronously with the frame stranding machine, stranding the aluminum wire passing through the reels onto the steel core. The stranding point between the aluminum wire and the steel core is located in cylindrical electrode two. The stranded corrosion-resistant overhead wire exits through the wiring hole. An oxidation power supply is also included, with cylindrical electrodes one and two connected to it. Electrolyte tank one, electrolyte tank two, cylindrical electrodes one and two, together with the oxidation power supply, constitute a dual plating tank system.

[0006] Furthermore, the stranded wire is mounted on the side wall of the electrolyte tank via bearings.

[0007] Furthermore, the sidewall of the electrolyte tank has a bearing seat, the stranded coil has an annular flange, and an annular bearing is mounted on the annular flange, the annular bearing being assembled inside the bearing seat.

[0008] Furthermore, the sidewalls at both ends of the first electrolyte tank and the sidewall of the second electrolyte tank near the first electrolyte tank have a sandwich layer, and a power output device is provided in the sandwich layer. The stranding reel rotates synchronously with the frame stranding machine under the drive of the power output device.

[0009] Furthermore, the power output device is a motor, the output shaft of which has a gear, and the outer edge of the winding reel has a toothed ring, which meshes with the gear.

[0010] Furthermore, the electrolyte cell is connected to an electrolyte circulation system. The plug is a silicone plug. The wire holes are symmetrically distributed around the central hole. The steel core is located on the axis of the cylindrical electrode.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This utility model discloses a stranding device for corrosion-resistant overhead lines, which improves upon the existing stranding method where the frame stranding machine and plating tank are stacked vertically. The frame stranding machine and the double plating tank system are arranged horizontally, making equipment installation and aluminum wire feeding simpler. The electrolyte circulation system can be set on the same plane as the electrolyte tank, reducing the height difference between the electrolyte tank and the electrolyte circulation system and reducing water pump energy consumption.

[0017] Example 1

[0018] like Figure 1-3As shown, a stranding device for a corrosion-resistant overhead line includes a frame stranding machine (not shown), an electrolyte tank 1, an electrolyte tank 2', a cylindrical electrode 1, and a cylindrical electrode 2', with the frame stranding machine located on one side. The cylindrical electrodes are placed flat in the electrolyte tanks, which contain electrolyte. Each of the two electrolyte tanks is connected to an electrolyte circulation system, and the two electrolyte circulation systems are independent of each other. The cylindrical electrodes are immersed in the electrolyte, and a steel core 3 passes horizontally from left to right through the frame stranding machine, electrolyte tank 1, and electrolyte tank 2', with a pre-coated insulating film layer on the surface of the steel core 3.

[0019] A stranded wire reel 5 is located on the sidewalls at both ends of electrolyte pool 1 and on the left sidewall of electrolyte pool 2'. A wiring hole 101 is located on the right sidewall of electrolyte pool 1'. The stranded wire reel 5 has a central hole 501, surrounded by ten wire holes 502 arranged symmetrically around the central hole 501. A steel core 3 passes through the central hole 501 into electrolyte pool 1 and electrolyte pool 2', and is positioned on the axis of the two cylindrical electrodes. An aluminum wire 6 is led out from the frame stranding machine and passes horizontally through the three stranded wire reels before entering electrolyte pool 1'. The frame stranding machine rotates around the steel core 3, and the three stranded wire reels 5 rotate synchronously with the frame stranding machine, stranding the aluminum wire 6 passing through the stranded wire reels 5 onto the steel core 3. The stranding point between the aluminum wire 6 and the steel core 3 is located in the cylindrical electrode 2'. The stranded corrosion-resistant overhead wire 7 exits through the wiring hole 101. Silicone plugs are installed on the center hole 501, wire hole 502, and wiring hole 101. Cylindrical electrode 1 2 and cylindrical electrode 2' are connected to the oxidation power supply.

[0020] The stranded wire reel 5 is mounted on the side wall of the electrolyte tank via a bearing assembly. The bearing assembly includes an annular bearing and a bearing housing. The bearing housing is located on the side wall of the electrolyte tank. The stranded wire reel 5 has an annular flange 503, on which an annular bearing is mounted. The annular bearing is assembled within the bearing housing. The side wall of the electrolyte tank on which the stranded wire reel 5 is mounted has a sandwich layer 102. A motor 8 is located within the sandwich layer 102. A gear is located on the output shaft of the motor 8. A toothed ring is located on the outer edge of the stranded wire reel 5 (the area with a diameter smaller than the annular flange). The gear meshes with the toothed ring. Driven by the motor 8, the stranded wire reel 5 rotates synchronously with the frame stranding machine, and the aluminum wire 6 is stranded onto the steel core 3 via the stranded wire reel 5 mounted on the side wall of the plating tank. The steel core 3 undergoes two oxidation processes as it travels within the two cylindrical electrodes. The aluminum wire 6 is oxidized and coated while rotating within the first cylindrical electrode 2. The aluminum wire 6 is twisted and oxidized a second time within the second cylindrical electrode 2'. Each aluminum wire 6 rotates around the axis of the two cylindrical electrodes within the two cylindrical electrodes to generate a uniform ceramic film by undergoing the same thermoelectrochemical oxidation conditions.
