Description

Technical Field

[0001] This utility model relates to the technical field of overhead line related equipment, specifically to an overhead steel-cored aluminum stranded wire recycling and stripping device. Background Technology

[0002] Overhead steel-cored aluminum stranded wire is widely used in fields such as power transmission and communication lines. When this type of stranded wire reaches the end of its service life or needs to be recycled due to line renovation, the common disposal method is to strip the insulation layer of the aluminum wire to recover the steel and aluminum cores.

[0003] Traditional wire stripping is typically done manually, which is inefficient and can easily damage the stranded wire, affecting the quality of recycled materials. While mechanical wire stripping equipment has emerged with technological advancements, the difficulty in maintaining stability during wire placement and transport leads to inconsistent contact pressure between the stripping blade and the wire, resulting in uneven thickness of the stripped aluminum wire and impacting subsequent recycling. Furthermore, many machines only perform unidirectional stripping on a single section of the stranded wire, requiring manual stripping again later. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an overhead steel-cored aluminum stranded wire recycling and stripping device, comprising a stripping platform, a semi-circular lower placement groove for placing the stranded wire at the top of the stripping platform, a lower lead screw at the bottom of the stripping platform, a lower slider threadedly connected to the outer side of the lower lead screw, a lower scraper mounted on the top of the lower slider, a lower through groove for the lower scraper to slide through the stripping platform below the lower placement groove, and the top of the lower scraper passing through the lower through groove; a pressure platform above the stripping platform, a semi-circular upper placement groove for placing the stranded wire at the bottom of the pressure platform, connecting strips fixed at both ends of the top of the pressure platform, a top frame fixed above the connecting strips, an upper lead screw rotatably connected between the two connecting strips, an upper slider threadedly connected to the outer side of the upper lead screw, an upper scraper mounted on the bottom of the upper slider, an upper through groove for the upper scraper to slide through the pressure platform above the upper placement groove, and the bottom of the upper scraper passing through the upper through groove.

[0005] Furthermore, a servo motor is installed on the bottom wall of the core stripping table. The output end of the servo motor is connected to a lower rotating rod, the end of which is fixed to a lower lead screw. An upper rotating rod is fixed to one end of the upper lead screw. A main spur gear is fixed to the outer side of the lower rotating rod. A lower receiving groove is provided on the core stripping table for the main spur gear to pass through. A driven spur gear is fixed to the outer side of the upper rotating rod. Upper receiving grooves are provided on the pressure table and the top frame for the driven spur gear to pass through. When the pressure table moves to contact the core stripping table, the driven spur gear meshes with the main spur gear.

[0006] Furthermore, a lifting cylinder is installed above the top frame, and the extension and retraction end of the lifting cylinder is fixed to the top frame.

[0007] Furthermore, the top of the stripping table is a flat surface on both sides of the lower through groove, which is used to contact the pressure table. The front and rear ends of the stripping table are inclined surfaces, with the lower end of the inclined surface connecting with the flat surface, so that the stranded wire can automatically fall into the lower placement groove.

[0008] Furthermore, side plates are fixed to the side walls of both connecting strips, and positioning posts are fixed to the top of the side plates. Two positioning holes are correspondingly opened on the top of the core stripping table.

[0009] The beneficial effects of this utility model are as follows: 1. By moving the upper and lower scrapers synchronously, the core stripping work in both directions is completed in one go, so that the outer insulation layer can be completely separated from the aluminum core without manual stripping. It can closely fit the outer surface of the stranded wire, and stably clamp the stranded wire in all directions to prevent the stranded wire from shifting or shaking during the stripping process, so as to achieve uniform and thorough stripping.

[0010] 2. Synchronous core stripping is achieved through gear transmission, reducing space occupation; the inclined core stripping table realizes automatic placement of stranded wire, and the cooperation between the positioning pin and the positioning hole can ensure the precise alignment of the pressing table and the core stripping table.

[0015] The present invention will be further described below with reference to the accompanying drawings: A device for recycling and stripping the core of overhead steel-cored aluminum stranded wire, such as Figure 1 As shown, the device includes a stripping table 1. The top of the stripping table 1 has a semi-circular lower storage groove 101 for placing the stranded wire. A lower lead screw 2 is located below the stripping table 1. A lower slider 3 is threaded onto the outer side of the lower lead screw 2. A lower scraper 4 is mounted on the top of the lower slider 3. The stripping table 1 has a lower through groove below the lower storage groove 101 for the lower scraper 4 to slide through, with the top of the lower scraper 4 passing through the lower through groove. A pressure table 5 is located above the stripping table 1. The bottom of the pressure table 5 has a semi-circular... The upper storage slot has a top frame 7 fixed above the connecting strip 6. A lifting cylinder 16 is installed above the top frame 7, and the telescopic end of the lifting cylinder 16 is fixed to the top frame 7. The top two ends of the pressure table 5 are fixed with connecting strips 6. An upper screw 8 is rotatably connected between the two connecting strips 6. An upper slider 9 is threadedly connected to the outer side of the upper screw 8. An upper scraper 10 is installed at the bottom of the upper slider 9. The pressure table 5 has an upper through groove above the upper storage slot for the upper scraper 10 to slide through. The bottom of the upper scraper 10 passes through the upper through groove.

[0016] The lower lead screw 2, the lower slider 3, and the lower scraper 4 form the bottom core stripping assembly. The lower scraper 4 performs core stripping operation on the bottom of the stranded wire through the lower through slot. The pressure table 5, the upper storage slot, the upper lead screw 8, the upper slider 9, and the upper scraper 10 form the top core stripping assembly. The lifting cylinder 16 can drive the pressure table 5 to move up and down to clamp the stranded wire.

[0017] like Figure 1 As shown, in this embodiment, a servo motor 11 is installed on the bottom wall of the core stripping table 1. The output end of the servo motor 11 is connected to a lower rotating rod 12. The end of the lower rotating rod 12 is fixed to the lower lead screw 2. An upper rotating rod 13 is fixed to one end of the upper lead screw 8. A main spur gear 14 is fixed to the outer side of the lower rotating rod 12. A lower receiving groove is provided on the core stripping table 1 for the main spur gear 14 to pass through. A driven spur gear 15 is fixed to the outer side of the upper rotating rod 13. An upper receiving groove is provided on the pressure table 5 and the top frame 7 for the driven spur gear 15 to pass through. When the pressure table 5 moves to contact the core stripping table 1, the driven spur gear 15 meshes with the main spur gear 14.

[0018] The servo motor 11 drives the lower lead screw 2 to rotate via the lower rotating rod 12. At the same time, the main spur gear 14 and the driven spur gear 15 mesh when the pressure table 5 contacts the core stripping table 1, transmitting power to the upper lead screw 8 so that the upper and lower scrapers 4 can move synchronously.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, the top of the core stripping table 1 is a plane 102 located on both sides of the lower through groove, which is used to contact the pressure table 5. The front and rear ends of the core stripping table 1 are inclined surfaces 103, and the lower end of the inclined surface 103 is connected to the plane 102 so that the stranded wire can automatically fall into the lower placement groove 101. The side walls of the two connecting strips 6 are fixed with side plates 17, and the top of the side plates 17 is fixed with positioning posts 18. The top of the core stripping table 1 has two corresponding positioning holes.

[0020] The inclined surface 103 of the stripping table 1 facilitates automatic feeding of stranded wires and reduces manual operation; the flat surface 102 is used for stable contact with the pressing table 5; the positioning post 18 and the positioning hole cooperate to ensure that the pressing table 5 and the stripping table 1 are accurately aligned.

[0021] The working principle of this utility model is as follows: When stripping the core of an overhead steel-cored aluminum stranded wire, the wire is placed in the lower placement slot 101 of the stripping table 1. By activating the lifting cylinder 16, the pressure table 5 is driven to move downwards. The upper placement slot at the bottom of the pressure table 5 cooperates with the lower placement slot 101 at the top of the stripping table 1 to clamp the wire in the middle. During this process, the positioning pin 18 is inserted into the positioning hole to ensure that the wire is stably positioned.

[0022] The servo motor 11 starts, driving the lower rotating rod 12 to rotate. The lower rotating rod 12 then drives the lower lead screw 2 to rotate. Since the lower lead screw 2 and the lower slide block 3 are connected by a thread, when the lower lead screw 2 rotates, the lower slide block 3 moves along the axial direction of the lower lead screw 2. The lower scraper 4 mounted on the top of the lower slide block 3 moves accordingly, its top passing through the lower through groove and performing core stripping operation along the bottom of the stranded wire. During its movement, the lower scraper 4 gradually removes the insulation layer of the aluminum wire through contact with the stranded wire, exposing the steel core.

[0023] Simultaneously, when the pressure table 5 moves to contact the core stripping table 1, the main spur gear 14 meshes with the driven spur gear 15. The rotation of the main spur gear 14 drives the driven spur gear 15 to rotate through gear meshing, thereby causing the upper lead screw 8 to rotate synchronously. As the upper lead screw 8 rotates, the upper slider 9 drives the upper scraper 10 to move axially along the upper lead screw 8, stripping the core from the top of the stranded wire. Driven by the servo motor 11, the upper scraper 10 and the lower scraper 4 move simultaneously along the stranded wire axially, stripping the core from both the top and bottom, which can evenly remove the insulation layer of the aluminum wire portion, realizing the recovery of the steel core while ensuring the integrity of the aluminum wire portion.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
