Description

Technical Field

[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 uniformly, the entire equipment is difficult to install. The vertical setting of the frame stranding machine is inconvenient for loading, and the large height difference between the two electrolyte tanks causes high energy consumption of the circulating water pump. Summary of the Invention

[0003] The purpose of the present invention is to provide a twisting device for corrosion-resistant overhead lines based on a dual-plating pool system, which improves the problems of difficult installation, inconvenient loading and high energy consumption of circulating water pumps in existing production equipment without affecting the uniformity of ceramic film growth.

[0004] In order to achieve the above-mentioned purpose of the invention, the technical solution of the present invention is as follows:

[0005] A twinning device for corrosion-resistant overhead lines based on a dual-plating tank system is characterized by comprising a horizontally arranged frame stranding machine, electrolyte tank 1, and electrolyte tank 2, each containing a horizontally arranged cylindrical electrode 1 and cylindrical electrode 2, respectively. The electrolyte tanks contain electrolyte, and the cylindrical electrodes are immersed in the electrolyte. A steel core passes through the frame stranding machine, electrolyte tank 1, and electrolyte tank 2 in sequence along the horizontal direction, and the surface of the steel core has a pre-coated insulating film layer. On the side walls of electrolyte tank 1 at both ends are stranding drum 1 and stranding drum 2, on the side wall of electrolyte tank 2 adjacent to electrolyte tank 1 is stranding drum 3, and on the other side wall of electrolyte tank 2 is a wiring hole. The stranding drum has a center hole in the center, and there are several wire holes around the center hole. The center hole, wire holes, and wiring holes are all plugged. The steel core passes through the electrolyte tanks from the center hole. After being pulled from the frame stranding machine, the aluminum conductor passes through the wire holes on stranding drums 1, 2, and 3, respectively, and enters electrolyte tank 2. The frame stranding machine rotates around the steel core, and the stranding drums rotate synchronously with the frame stranding machine, twisting the aluminum conductor passed through the stranding drums onto the steel core. The aluminum conductor and the steel core are twisted together in cylindrical electrode 2, and the twisted corrosion-resistant overhead wire exits through the wiring hole. An oxidizing power source is also included, and cylindrical electrodes 1 and 2 are connected to the oxidizing power source respectively. Electrolyte tanks 1 and 2, together with the oxidizing power source, form a dual-cell plating system.

[0006] Furthermore, the winch drum is mounted on the side wall of the electrolyte tank via a bearing.

[0007] Furthermore, the side wall of the electrolyte tank has a bearing seat, the wire drum has an annular flange, the annular flange has an annular bearing, and the annular bearing is assembled in the bearing seat.

[0008] Furthermore, the side walls at both ends of the electrolyte cell one and the side wall of the electrolyte cell two close to the electrolyte cell one have interlayers, and a power output device is provided in the interlayer. The strands rotate synchronously with the frame stranding machine under the drive of the power output device.

[0009] Furthermore, the power output device is a motor, a gear is provided on the motor output shaft, a gear ring is provided on the outer edge of the winch drum, and the gear is meshed with the gear ring.

[0010] Furthermore, the electrolyte tank is connected to an electrolyte circulation system. The plug is a silicone plug. The wire holes are axially 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 the present invention are:

[0012] The invention discloses a twisting device for corrosion-resistant overhead wires based on a dual-plating tank system, which improves the existing twisting method in which a frame stranding machine and a plating tank are stacked one above the other. The frame stranding machine and the dual-plating tank system are arranged horizontally, which simplifies equipment installation and aluminum wire feeding. The electrolyte circulation system can be arranged on the same plane as the electrolyte tank, thereby reducing the height difference between the electrolyte tank and the electrolyte circulation system and reducing water pump energy consumption.

[0016] The following describes the technical solution of the present invention in a clear and complete manner, with reference to specific embodiments. The pre-coated insulating film, the simultaneous plating of the steel core and aluminum conductor in the same bath, the electrolyte and its circulation system, the oxidizing power source, the plating bath system, and the silicone plugs involved are all prior art. For details, reference may be made to the disclosures in patents CN118087000B, CN118888222B, and CN218561666U.

[0017] Example 1

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

[0019] A cable drum 5 is located on each end of the electrolyte cell 1 and on the left side of the second electrolyte cell 1'. A cable routing hole 101 is located on the right side of the electrolyte cell 1'. The cable drum 5 has a central hole 501, surrounded by ten cable holes 502, distributed axially symmetrically around the central hole 501. A steel core 3 passes through the central hole 501 through both electrolyte cells 1 and 2, 1', and is positioned on the axis of the two cylindrical electrodes. Aluminum conductor 6 is drawn from a stranding machine and horizontally passes through three stranding drums before entering the electrolyte cell 1'. The stranding machine rotates around the steel core 3, and the three stranding drums 5 rotate synchronously with the machine, stranding the aluminum conductor 6 that has passed through the stranding drums 5 onto the steel core 3. The junction between the aluminum conductor 6 and the steel core 3 is located within the second cylindrical electrode 2'. The stranded, corrosion-resistant overhead wire 7 then exits the cable routing hole 101. There are silicone plugs on the center hole 501, the wire hole 502 and the wiring hole 101. The cylindrical electrode 1 2 and the cylindrical electrode 2 2' are connected to the oxidation power supply respectively.

[0020] The winding drum 5 is mounted on the side wall of the electrolyte tank via a bearing assembly. The bearing assembly comprises an annular bearing and a bearing seat, with the bearing seat positioned on the side wall. The winding drum 5 has an annular flange 503, affixed to the annular bearing, and assembled within the bearing seat. The electrolyte tank side wall where the winding drum 5 is mounted has an interlayer 102, within which is a motor 8. A gear is mounted on the output shaft of the motor 8. A gear ring is meshed with the gear ring on the outer edge of the winding drum 5 (the area with a smaller diameter than the annular flange). Driven by the motor 8, the winding drum 5 rotates synchronously with the frame stranding machine. The winding drum 5, mounted on the side wall of the plating tank, strands the aluminum conductor 6 onto the steel core 3. The steel core 3 undergoes two oxidation cycles as it travels within the two cylindrical electrodes. The aluminum conductor 6 undergoes oxidation and plating while rotating within cylindrical electrode 1 2. The aluminum conductor 6 undergoes two oxidation cycles within cylindrical electrode 2 2' while stranding. Each aluminum wire 6 rotates around the axis of the cylindrical electrode within the two cylindrical electrodes, so as to generate a uniform ceramic film layer in a manner that the aluminum wires are subjected to the same thermo-electrochemical oxidation conditions.
