Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable processing equipment, and in particular to a winding auxiliary frame for processing high-voltage wires inside cables. Background Technology

[0002] The high-voltage cable winding auxiliary frame is a specialized tooling device designed specifically for the winding process in high-voltage cable production. Its core function is to precisely fix the cable substrate and, in conjunction with the winding mechanism, achieve uniform coverage of the insulation layer, shielding layer, or protective tape, ensuring the structural stability and electrical performance of the high-voltage cable. The equipment employs an adjustable clamping structure to accommodate different cable diameters, and its anti-slip positioning design prevents cable shifting and twisting during processing. The frame integrates a rotary guide component, reducing winding resistance while ensuring uniform winding tension, minimizing interlayer gaps or overlap defects. The overall structure combines rigidity and flexibility, facilitating integration with the production line, improving winding efficiency and processing accuracy, and providing reliable assurance for the high-voltage resistance and interference resistance of high-voltage cables. It is widely used in high-voltage cable manufacturing scenarios in power transmission, industrial equipment, and other fields.

[0003] Patent CN223175465U discloses a winding auxiliary frame for processing high-voltage wires inside cables, including a base frame. The top of the base frame is provided with a wire support tray for supporting the wire coil used in high-voltage wire processing. A limiting component for the center of the wire coil is provided at the center of the wire support tray. This invention, through the assembly of the base frame, wire support tray, and limiting component, provides a winding auxiliary frame structure for high-voltage wires used in processing and winding high-voltage wires inside cables, ensuring the stability of the high-voltage wires during the unwinding process by the winding equipment.

[0004] While existing winding auxiliary frames for high-voltage wire processing inside cables, consisting of a base frame, wire support reel, and limiting components, provide a winding auxiliary structure for high-voltage conductors used in cable winding, ensuring the stability of the high-voltage conductors during the winding process, they face several prominent problems in practical use. Specifically, the limiting components only fix the center of the wire roll using baffles, failing to constrain the radial outer edge of the wire roll. This affects the continuity of processing. Therefore, to address these shortcomings of existing technology, we urgently need an innovative winding auxiliary frame for high-voltage wire processing inside cables to solve these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a winding auxiliary frame for processing high-voltage wires inside cables. It solves the problem that the limiting component only fixes the center of the cable coil through baffles, failing to constrain the radial outer side of the cable coil. This can even lead to disordered cable winding and affect the continuity of processing.

[0006] The system includes an external protective assembly, which comprises two circular protective hollow panels in corresponding positions. Each of the two circular protective hollow panels has six installation notches on its outer surface, arranged in groups of three. Each group of installation notches is evenly distributed on the outer surface of the circular protective hollow panels. Installation rods are fixedly connected to the inner walls of the three rear installation notches. A protective limiting rod is movably connected to the side surface of each installation rod. A strip-shaped fixing plate is fixedly connected to the front end of the protective limiting rod, and the inner surface of the strip-shaped fixing plate is movably connected to the outer surface of the front circular protective hollow panel.

[0007] The two sets of installation notches correspond to each other. There are three protective limit rods and three strip fixing plates. The three strip fixing plates and the outer surface of the front circular protective hollow plate are all provided with threaded holes.

[0008] A cable head fixing assembly is provided between the two circular protective hollow plates. The cable head fixing assembly includes a winding cylinder with a strip-shaped insertion groove on its side surface. The two sides of the winding cylinder are respectively fixedly connected to the inner surfaces of the two circular protective hollow plates.

[0009] A fixing strip is fixedly connected to the left side of the inner wall of the winding drum, and an auxiliary support plate is fixedly connected between the fixing strip and the winding drum.

[0010] The winding drum has a strip-shaped mounting plate fixedly connected to the right side of its inner wall. An electric telescopic rod is fixedly connected through the inside of the strip-shaped mounting plate, and a pressing plate is fixedly connected to the output end of the electric telescopic rod.

[0011] The outer surface of the extrusion plate is fixedly connected with a rubber friction block, and the rubber friction block is a number and evenly distributed on the outer surface of the extrusion plate.

[0012] The inner wall of the winding drum is fixedly connected to a reinforcing plate, and the bottom of the fixing strip and the strip mounting plate are both fixedly connected to the upper surface of the reinforcing plate.

[0013] 1. In this utility model, by setting external protective components, including two corresponding circular protective hollow plates, mounting rods, protective limiting rods and strip fixing plates, the outermost side of the cable roll is fully surrounded and radially limited, avoiding loosening and decoupling of high-voltage lines or edge cable friction damage during winding or unwinding. This achieves stable adaptation and outer protection for cable rolls of different specifications, ensuring processing continuity and cable product quality.

[0014] 2. In this utility model, by setting a cable head fixing component, including a winding cylinder with a strip-shaped insertion groove, a fixing strip, an electric telescopic rod, a squeezing plate and a rubber friction block, the high-voltage cable head can be quickly inserted and clamped and fixed by the squeezing plate, avoiding the problem of cable head falling off or not being firmly fixed in the initial stage of winding, which leads to winding disorder. This achieves convenient and stable fixing of the cable head and improves the starting accuracy and efficiency of winding operation. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5A winding auxiliary frame for processing high-voltage wires inside cables includes an external protective component 1. The external protective component 1 includes two circular protective hollow plates 101, which are positioned correspondingly. The outer surfaces of the two circular protective hollow plates 101 are provided with installation notches 102. There are six installation notches 102, and three installation notches 102 are grouped together. Each group of installation notches 102 is evenly distributed on the outer surface of the circular protective hollow plates 101. The inner walls of the three rear installation notches 102 are fixedly connected to installation rods 103. The side surfaces of the installation rods 103 are movably connected to protective limiting rods 104. The front end of the protective limiting rods 104 is fixedly connected to strip fixing plates 105. The inner surface of the strip fixing plates 105 is movably connected to the outer surface of the front circular protective hollow plates 101. The two sets of mounting notches 102 correspond to each other. There are three protective limiting rods 104 and three strip fixing plates 105. Each of the three strip fixing plates 105 and the outer surface of the front circular protective hollow plate 101 has threaded holes 106. When performing external protection and limiting operations on the cable reel, first, based on the outer diameter of the cable reel to be processed, the penetration length of the protective limiting rods 104 on the side surface of the mounting rod 103 is adjusted so that the three protective limiting rods 104 form a surrounding range along the radial direction of the circular protective hollow plate 101 that matches the outer contour of the cable reel. Because the two sets of mounting notches 102 are positioned correspondingly, and the protective limiting rods 104 and the mounting rod 103 are movably connected, their extension distance can be flexibly adjusted to accommodate cable reels of different diameters. After adjustment, the strip fixing plate 105 and the front circular protective hollow plate 101 are fixedly connected by bolts or other fasteners through the threaded holes 106 on the outer surface of the strip fixing plate 105 and the front circular protective hollow plate 101, thereby locking the position of the protective limiting rod 104. At this time, the two corresponding circular protective hollow plates 101 form axial limits from both sides of the cable roll, and the three evenly distributed protective limiting rods 104 form a radial enclosure from the outer periphery of the cable roll, together constituting an all-round protective structure for the outside of the cable roll, effectively limiting the radial sway and axial displacement of the cable roll during winding or unwinding.

[0024] Please see Figures 1-5Based on the first embodiment, a cable head fixing assembly 2 is provided between the two circular protective hollow plates 101. The cable head fixing assembly 2 includes a winding cylinder 201, and a strip-shaped insertion groove 202 is opened on the side surface of the winding cylinder 201. The two sides of the winding cylinder 201 are respectively fixedly connected to the inner surfaces of the two circular protective hollow plates 101. A fixing strip 203 is fixedly connected to the left side of the inner wall of the winding cylinder 201, and an auxiliary support plate 204 is fixedly connected between the fixing strip 203 and the winding cylinder 201. A strip-shaped mounting plate 205 is fixedly connected to the right side of the inner wall of the winding cylinder 201. An electric telescopic rod 206 is fixedly passed through the inside of the strip-shaped mounting plate 205, and a pressing plate 207 is fixedly connected to the output end of the electric telescopic rod 206. A number of rubber friction blocks 208 are fixedly connected to the outer surface of the pressing plate 207 and are evenly distributed on the outer surface of the pressing plate 207. A reinforcing plate 209 is fixedly connected to the inner wall of the winding drum 201. The bottom of the fixing strip 203 and the strip mounting plate 205 are both fixedly connected to the upper surface of the reinforcing plate 209. At the beginning of the high-voltage wire winding operation, when the high-voltage wire end needs to be fixed, the high-voltage wire end is inserted into the winding drum 201 through the strip insertion groove 202 on the side surface of the winding drum 201, placing the wire end in the gap between the fixing strip 203 and the extrusion plate 207. The fixing strip 203 maintains a stable posture under the reinforcement of the auxiliary support plate 204, providing lateral support for the wire end. Subsequently, the electric telescopic rod 206, which is fixedly connected inside the strip mounting plate 205, is activated. Its output section pushes the extrusion plate 207 axially toward the fixing strip 203 until the rubber friction blocks 208 evenly distributed on the outer surface of the extrusion plate 207 make tight contact with the high-voltage wire end. The rubber friction blocks 208 increase the friction between the extrusion plate 207 and the wire end, enhancing the clamping effect while avoiding hard damage to the surface of the high-voltage wire. In addition, the reinforcing plate 209 on the inner wall of the winding drum 201 provides bottom support for the fixing strip 203 and the strip mounting plate 205, ensuring that the two maintain structural stability during the clamping process, thereby achieving a firm fixation of the high-voltage wire end throughout the winding process and preventing the wire end from falling off and causing winding disorder.

[0025] Working Principle: First, for the high-voltage wire coil to be processed, the external protective component 1 needs to be debugged and assembled. Specifically, based on the actual outer diameter of the wire coil, the movable penetration length of the protective limiting rod 104 on the side surface of the mounting rod 103 is adjusted so that the three protective limiting rods 104, evenly distributed along the outer circumference of the circular protective hollow plate 101, form a surrounding range that matches the outer contour of the wire coil. Since the three rear mounting notches 102 correspond to the three front mounting notches 102, and the protective limiting rods 104 can flexibly extend and retract along the axial direction of the mounting rod 103, they can adapt to wire coils of different diameters. After adjustment to the appropriate position, the strip fixing plate 105 and the threaded holes 106 on the outer surface of the front circular protective hollow plate 101 are fastened together using bolts or other fasteners to lock the extension length of the protective limiting rods 104. At this point, the two corresponding circular protective hollow plates 101 form a barrier from both sides of the wire roll along the axial direction, preventing the wire roll from shifting axially; the three protective limiting rods 104 form a surrounding limit from the outer periphery of the wire roll, together constituting an all-round protective structure for the outside of the wire roll, providing a stable constraint foundation for subsequent winding operations. Subsequently, the wire end fixing operation of the initial stage of high-voltage wire winding is carried out. The starting end of the high-voltage wire is inserted into the winding cylinder 201 through the strip insertion groove 202 on the side surface of the winding cylinder 201 in the wire end fixing assembly 2, so that the wire end is naturally placed in the gap between the fixing strip plate 203 and the extrusion plate 207. The fixing strip plate 203 maintains a vertical and stable posture under the reinforcement of the auxiliary support plate 204, providing rigid support on one side for the wire end; the reinforcing plate 209 on the inner wall of the winding cylinder 201 forms bottom support for the fixing strip plate 203 and the strip mounting plate 205, ensuring that neither of them deforms under force. The electric telescopic rod 206, which is fixed and runs through the inside of the strip mounting plate 205, is activated. Its output end pushes the extrusion plate 207 horizontally toward the fixed strip plate 203 until the rubber friction blocks 208 evenly distributed on the outer surface of the extrusion plate 207 make close contact with the high-voltage wire end and generate extrusion force. The rubber friction blocks 208 not only improve clamping stability by increasing the friction of the contact surface, but also prevent damage to the insulation layer of the high-voltage wire surface caused by hard contact, thus achieving flexible fastening of the wire end. After completing the above preparations, the winding equipment can be started to wind or unwind the high-voltage wire. During this process, under the constraint of the external protective component 1, the wire coil will not loosen or come off due to radial tension fluctuations, nor will it shift along the axial direction. At the same time, the wire end remains stable under the continuous clamping action of the cable end fixing component 2, and will not fall off or shift due to winding tension. Through the coordinated work of the external protective component 1 and the cable end fixing component 2, the entire high-voltage wire winding process is ensured to proceed in an orderly and stable manner, effectively improving processing accuracy and work efficiency.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
