Description

TECHNICAL FIELD

[0001] The utility model relates to steel core aluminium stranded conductor technical field especially relates to a steel core aluminium stranded conductor quick wire stripping device. BACKGROUND

[0002] Steel core aluminium stranded conductor, as a kind of conductor widely used in overhead transmission line, is twisted by aluminium wire and steel wire. It combines the high conductivity of aluminium and the high strength of steel, so that the conductor not only has good mechanical properties, but also can effectively transmit electric energy. The internal of steel core aluminium stranded conductor is steel "core", and the external is aluminium wire wound around the steel core by twisting. The steel core mainly plays the role of increasing strength, and the aluminium stranded conductor is used for transmitting electric energy. This kind of conductor has simple structure, convenient erection and maintenance, low line cost, large transmission capacity, good conductivity and sufficient mechanical strength, so it is widely used in overhead transmission and distribution lines of various voltage levels.

[0003] In the production or maintenance process of steel core aluminium stranded conductor, the internal steel core needs to be extracted sometimes. This operation is usually for a variety of reasons. On the one hand, the steel core may be extracted for replacing or repairing the damaged steel core part to ensure the overall strength and safety of the conductor. On the other hand, with the progress of technology and the application of new energy-saving conductors, sometimes the steel core in traditional steel core aluminium stranded conductor needs to be replaced by materials with higher conductivity or lighter weight to reduce line loss and improve power transmission efficiency. In addition, in specific situations, such as when the conductor needs to be recycled, it is also necessary to separate the aluminium wire and the steel wire for recycling and recycling to realize effective recycling of resources. These reasons jointly promote the demand for extracting the internal steel core of steel core aluminium stranded conductor in specific situations.

[0004] Patent document CN214410878U discloses a steel core aluminium stranded conductor stripping and recycling device, which comprises a winding roller for winding the steel core aluminium stranded conductor and a stripping cylinder for stripping the steel core aluminium stranded conductor. The winding roller is provided with two groups of guide rollers with guiding function from far to near, a heating cylinder with heating function and a stripping cylinder. The inner wall of the stripping cylinder is inlaid with four groups of annularly arranged piston cylinders, and each group of piston cylinders is slidably connected with a cutting knife. The cutting knife and the inner wall of the piston cylinder are connected by a group of return springs, and the cutting end of the cutting knife extends to the outside of the piston cylinder. The inner wall of the heating cylinder has a gap, and the gap is filled with a heating layer and a heat conducting layer. The heating layer is tightly attached to the outside of the heat conducting layer, and a plurality of groups of annularly arrayed heating pipes are embedded in the heating layer. The steel core aluminium stranded conductor stripping and recycling device has simple structure and stable transmission.

[0005] In the prior art of the aforementioned patent, the steel-cored aluminum stranded wire to be stripped is cut by a cutting blade inside the stripping cylinder. However, since the thickness of the outer aluminum stranded wire varies between different batches of steel-cored aluminum stranded wire, the cutting depth of the cutting blade varies. The aforementioned device only achieves the cutting blade to cut the aluminum stranded wire by placing a spring between the cutting blade and the inner wall of the stripping cylinder. However, this cutting is a destructive cutting. Although the steel core has a high hardness, it will still cause scratches to the steel core during cutting. How to adjust the cutting thickness of the cutting blade is a problem to be solved in the prior art. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5A quick stripper for steel-cored aluminum stranded wire includes a support plate 1. A through groove 3 is formed on the support plate 1. Screws 4 are rotatably mounted on the top and bottom walls of the through groove 3. Two screws 4 are arranged opposite each other, and a limit connecting ring 5 is fixedly connected between the two screws 4. Adjusting sliders 6 are threaded onto each of the two screws 4, and each adjusting slider 6 is equipped with a cutting component. A first motor 2 is fixedly mounted on the top of the support plate 1, and the output end of the first motor 2 is connected to the screws 4. A fixing frame 15 is fixedly mounted on the side wall of the support plate 1. A stripping tube 16 is fixedly mounted on the fixing frame 15, and a feeding component is provided at one end of the stripping tube 16. Two cutting components are respectively positioned above and below the stripping tube 16. A turbine thickness gauge body 12 and a control terminal 13 are fixedly mounted on the top of the support plate 1. Data transmission lines 14 are respectively provided at both ends of the control terminal 13. The control terminal 13 is connected to the turbine thickness gauge body 12 and the control terminal 13 via the data transmission lines 14. The first motor 2 is electrically connected; the feeding assembly feeds the steel-cored aluminum stranded wire to be stripped into the stripping cylinder. Before feeding into the stripping cylinder, the thickness of the aluminum stranded wire on the surface of the steel core is detected by the turbine thickness gauge body 12. This instrument is very suitable for measuring the thickness of non-ferrous metals (such as aluminum) covering ferromagnetic substrates (such as steel). It is based on the principle of electromagnetic induction. When the probe of the eddy current thickness gauge approaches the coating surface, eddy currents are generated between the coating and the substrate. The size and distribution of the eddy currents are affected by the coating thickness. The thickness of the coating layer can be indirectly obtained by measuring the change of the eddy currents. Since this device is existing technology, it will not be described in detail. After measuring the thickness of the batch of steel-cored aluminum stranded wire, the first motor 2 is controlled by the control terminal 13. The first motor 2 rotates, driving the relatively set screw 4 to rotate. The rotation of the two screws 4 can realize the relative up and down movement of the two adjusting sliders 6, thereby controlling the cutting thickness of the steel-cored aluminum stranded wire by the two cutting wheels 7. It can control the non-destructive cutting of the cutting wheels 7, increasing the efficiency of the stripping work and the yield rate.

[0025] As a preferred embodiment, the cutting assembly includes a second motor 8 fixedly mounted on the side wall of the adjusting slider 6. The output end of the second motor 8 is connected to a rotating shaft 9. One end of the rotating shaft 9 is fixedly connected to a cutting wheel 7. Cutting grooves 20 are provided at both the top and bottom ends of the stripping tube 16. The two cutting wheels 7 are respectively disposed inside the cutting grooves 20. The two second motors 8 can drive the rotating shaft 9 to rotate, thereby controlling the rotation of the cutting wheels 7 to cut the steel-cored aluminum stranded wire. The cutting grooves 20 are large in size and will not affect the cutting of the cutting wheels 7. The cutting wheels 7 cut the wire inside the stripping tube 16 through the cutting grooves 20. The stripping tube 16 can shield the sparks generated during the cutting process, thus playing a protective role.

[0026] As a preferred technical solution of this embodiment, the feeding assembly includes a third motor 10, which is fixedly installed on the side wall of the support plate 1. The output end of the third motor 10 is connected to a feeding roller 11, which is located on one side of the turbine thickness gauge body 12. A section of the steel-cored aluminum stranded wire wound on the feeding roller 11 passes through the stripping tube 16. When the third motor 10 drives the feeding roller 11 to rotate, the steel-cored aluminum stranded wire wound on the feeding roller 11 can be continuously discharged in conjunction with the tension generated by the two cutting wheels during cutting.

[0027] As a preferred embodiment, slide rods 18 are slidably installed at both the top and bottom of the stripping tube 16. Springs 19 are provided on both slide rods 18. One end of each spring 19 is fixedly connected to the slide rod 18, and the other end is fixedly connected to the surface of the stripping tube 16. Guide arc plates 17 are fixedly installed at the bottom of both slide rods 18. Since the thickness of each batch of steel-cored aluminum stranded wire is different, the steel-cored aluminum stranded wire entering the stripping tube 16 must be positioned precisely between the two cutting wheels 7. The steel-cored aluminum stranded wire enters between the two guide arc plates 17 and exits from the end closest to the cutting wheel 7. Under the action of the springs 19, the two guide arc plates 17 can press the steel-cored aluminum stranded wire towards the center, ensuring it is positioned precisely between the two cutting wheels 7.

[0028] As a preferred technical solution of this embodiment, the upper guide arc plate 17 is inclined downward at one end near the cutting wheel 7, and the lower guide arc plate 17 is inclined upward at one end near the cutting wheel 7; the two inclined guide arc plates 17 can correct and limit the steel-cored aluminum stranded wire, so that the steel-cored aluminum stranded wire can be fed into the two cutting wheels 7 in a balanced and stable manner.

[0029] As a preferred technical solution in this embodiment, fixing blocks 21 are fixedly installed at the bottom ends of both ends of the support plate 1; the setting of fixing blocks 21 can increase the stability of the support plate 1 and increase the safety of the device when it is working.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
