Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and in particular to a non-standard stranded conductor power cable and its stranding processing device. Background Technology

[0002] Shaped stranded conductor power cables are a type of power cable with a specially designed conductor structure. Their core feature is that the conductor is made of non-circular, irregularly shaped single wires stranded together. This design offers significant advantages over traditional round stranded conductor cables in terms of electrical performance, mechanical performance, material utilization, and environmental adaptability. The stranding processing equipment for shaped stranded conductor power cables is a key piece of equipment in cable production, and its core function is to achieve high-precision stranding of the irregularly shaped single wires.

[0003] In the existing technology, whenever the stranding processing equipment is used, the operator must first remove the nuts used to precisely limit the position of the stranding rollers one by one, and then take out the exhausted or replaced stranding rollers from the equipment and replace them with new ones. This process takes a long time and results in low efficiency, which reduces the efficiency of cable stranding and the practicality of the equipment. Therefore, it is necessary to improve the design of a non-shaped stranded conductor power cable and its stranding processing equipment to solve the above problems. Utility Model Content

[0004] To overcome the problem that when it is necessary to replace the wire roller, the operator must first remove the nuts used to precisely limit the wire roller one by one, and then take the exhausted or replaced wire roller out of the device and replace it with a new wire roller, which leads to low efficiency in replacing the wire roller and reduces the efficiency of cable stranding processing.

[0005] The technical solution of this utility model is as follows: a stranding processing device for irregularly shaped stranded conductor power cables, including a base plate, a plug rod, and a stranding assembly. A support plate is fixedly connected to the top of the base plate, a stranding cylinder is fixedly connected to the top of the base plate, and a wrapping unit for wrapping the stranded conductor is fixedly connected to the top of the base plate. A stranding assembly for stranding the conductor is provided on the top of the base plate. The stranding assembly is provided with a U-shaped seat, which is located on the top of the base plate. A wire roller body is provided inside the U-shaped seat, and a plug rod is provided inside the U-shaped seat. The wire roller body is located on the plug rod. A lever is fixedly connected to one end of the plug rod, and a fixing frame is fixedly connected to the end of the U-shaped seat away from the lever. A locking block is slidably connected inside the fixing frame and is located inside the plug rod.

[0006] Preferably, the U-shaped seat and the roller body are provided with matching through holes at corresponding positions of the insert rod, and the insert rod is set inside the through holes of the U-shaped seat and the roller body.

[0007] Preferably, the insert rod has a matching annular groove at the corresponding position of the locking block, and the locking block is set in the groove of the insert rod.

[0008] Preferably, an optical axis is fixedly connected inside the fixed frame, a lever is fixedly connected to the right end of the card block, the lever is slidably connected inside the fixed frame and on the optical axis, and a spring is fixedly connected between the lever and the fixed frame.

[0009] Preferably, the stranding assembly includes a motor, which is fixedly connected to the top of the base plate. A large gear is fixedly connected to the output end of the motor. The large gear is rotatably connected to the support plate. A small gear meshes with the outside of the large gear. A first rotating rod is fixedly connected to the inside of the small gear. The first rotating rod is rotatably connected to the inside of the support plate. A second rotating rod is fixedly connected to the left end of the first rotating rod. A guide frame is fixedly connected to the second rotating rod. A protective pad for protecting the conductor is fixedly connected to the guide frame. A fixing frame is fixedly connected to the first rotating rod. A U-shaped seat is fixedly connected to the left end of the fixing frame.

[0010] Preferably, the guide frame has four sets of guide holes for easy passage of conductors. The guide holes are symmetrically distributed on the guide frame, and four sets of protective pads are provided. The four sets of protective pads are fixed inside the four sets of guide holes in sequence.

[0011] This utility model also provides a non-linear stranded conductor power cable, which includes the non-linear stranded conductor power cable stranding processing device as described above, and further includes a cable conductor. The cable conductor is disposed on the roller body. An insulation layer is fixedly connected to the outside of the cable conductor. A first wrapping tape is wrapped around the outside of the insulation layer. A filling layer is disposed between the first wrapping tape and the insulation layer. An inner sheath is wrapped around the outside of the first wrapping tape. A second wrapping tape is wrapped around the outside of the inner sheath. A non-magnetic metal wire armor layer is disposed between the inner sheath and the second wrapping tape. An outer sheath is wrapped around the outside of the second wrapping tape.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to the previous method where, when replacing the wire roller, the locking block is moved away from the slot of the insertion rod to release the limiting position of the insertion rod, and the insertion rod is pulled out from the U-shaped seat and the wire roller body by the lever, making it easier to replace the wire roller body, the method involves aligning the through hole of the wire roller body into the through hole of the U-shaped seat, and then locking the insertion rod into the annular groove of the insertion rod to limit the insertion rod so that it can only rotate, thus completing the replacement of the wire roller body. This method improves the convenience of replacing the wire roller body and avoids the problem that operators must first remove the nuts used for precise positioning of the wire roller one by one, and then take out the exhausted or replacement wire roller from the device and replace it with a new wire roller, which leads to low efficiency in replacing wire rollers and reduces the efficiency of cable stranding processing.

[0014] 2. By inserting the cable conductor end into the guide hole of the guide frame, then through the stranding drum and the finished product unit, it is connected to the external winding roller. Then, the fixed frame and the guide frame rotate together, thereby stranding the cable conductor together. The protective pad prevents damage to the cable conductor during stranding, thereby improving the stranding efficiency of the cable conductor and enhancing the practicality of the device.

[0015] 3. The inner sheath is made of polyethylene extrusion material to prevent external forces from damaging the cable conductor. The non-magnetic metal wire armor layer is made of aluminum wire, which increases the cable's current carrying capacity, reduces eddy current loss, ensures the normal operation of the cable, and also improves the cable's safety performance.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of a stranding processing device for irregularly shaped stranded conductor power cables, including a base plate 1, a plug rod 21, and a stranding assembly. A support plate 7 is fixedly connected to the top of the base plate 1, a stranding cylinder 5 is fixedly connected to the top of the base plate 1, and a wrapping unit 6 for wrapping the stranded conductor is fixedly connected to the top of the base plate 1. A stranding assembly for stranding the conductor is provided on the top of the base plate 1. The stranding assembly is provided with a U-shaped seat 39, which is located on the top of the base plate 1. A wire roller body 310 is provided inside the U-shaped seat 39, and the plug rod 21 is provided inside the U-shaped seat 39. The wire roller body 310 is located on the plug rod 21. A lever 22 is fixedly connected to one end of the plug rod 21, and a fixing frame 23 is fixedly connected to the end of the U-shaped seat 39 away from the lever 22. A locking block 27 is slidably connected inside the fixing frame 23 and is located inside the plug rod 21. The lever 22 is used to make the conductor stranded. The insertion rod 21 is pulled out from the U-shaped seat 39 and the inside of the wire roller body 310 to facilitate the replacement of the wire roller body 310. The wire roller body 310 is aligned with the through hole and inserted into the through hole of the U-shaped seat 39. Then, the locking block 27 is inserted into the annular groove of the insertion rod 21 to limit the insertion rod 21 so that the insertion rod 21 can only rotate, thus completing the replacement of the wire roller body 310 and improving the convenience of replacing the wire roller body 310. The stranding assembly inserts the end of the cable conductor 41 into the guide hole of the guide frame 36, then through the stranding cylinder 5 and the finished product unit 6 to connect it with the external winding roller. Then, the fixing frame 38 and the guide frame 36 rotate together to strand the cable conductor 41 together. The protective pad 37 prevents the cable conductor 41 from being damaged during stranding, thereby improving the stranding efficiency of the cable conductor 41 and improving the practicality of the device.

[0024] Please see Figure 4 - Figure 5In this embodiment, the U-shaped seat 39 and the roller body 310 both have corresponding through holes at the corresponding positions of the insertion rod 21. The insertion rod 21 is disposed inside the through holes of the U-shaped seat 39 and the roller body 310, making it easy to align and insert the insertion rod 21, facilitating the replacement of the roller body 310, and improving the stranding efficiency of the cable conductor 41. The insertion rod 21 has a corresponding annular groove at the corresponding position of the locking block 27. The locking block 27 is disposed in the groove of the insertion rod 21, allowing it to be locked into the annular groove, thus limiting the insertion rod 21 and ensuring that it can only rotate within the through hole of the U-shaped seat 39, thereby improving the stability of the device. The optical shaft 25 is fixedly connected inside the fixed frame 23, and the right end of the locking block 27 is fixedly connected to... A lever 24 is slidably connected inside the fixed frame 23 and slidably connected to the optical shaft 25. A spring 26 is fixedly connected between the lever 24 and the fixed frame 23. By moving the locking block 27 away from the slot of the insertion rod 21, the limiting position of the insertion rod 21 is released. The lever 22 is used to pull the insertion rod 21 out from the U-shaped seat 39 and the inside of the roller body 310, making it convenient to replace the roller body 310. By aligning the through hole of the roller body 310 with the through hole of the U-shaped seat 39, and then locking the locking block 27 into the annular groove of the insertion rod 21, the insertion rod 21 is limited, so that the insertion rod 21 can only rotate, thus completing the replacement of the roller body 310 and improving the convenience of replacing the roller body 310.

[0025] Please see Figure 2 - Figure 3In this embodiment, the stranding assembly includes a motor 31, which is fixedly connected to the top of the base plate 1. A large gear 32 is fixedly connected to the output end of the motor 31. The large gear 32 is rotatably connected to the support plate 7. A small gear 33 meshes with the outside of the large gear 32. A first rotating rod 34 is fixedly connected inside the small gear 33. The first rotating rod 34 is rotatably connected inside the support plate 7. A second rotating rod 35 is fixedly connected to the left end of the first rotating rod 34. A guide frame 36 is fixedly connected to the second rotating rod 35. A protective pad 37 for protecting the conductor is fixedly connected to the guide frame 36. A fixing frame 38 is fixedly connected to the first rotating rod 34. A U-shaped seat 39 is fixedly connected to the left end of the fixing frame 38. The stranding assembly inserts the cable conductor 41 wire end into the guide frame 35. The guide frame 36 has guide holes, through which the stranding cylinder 5 and the finished product unit 6 are passed to connect with the external take-up roller. Then, the guide frame 36 and the fixed frame 38 rotate together, thereby stranding the cable conductors 41 together. The protective pads 37 prevent damage to the cable conductors 41 during stranding, thereby improving the stranding efficiency of the cable conductors 41 and enhancing the practicality of the device. The guide frame 36 has four sets of guide holes for easy conductor passage. The guide holes are symmetrically distributed on the guide frame 36, and four sets of protective pads 37 are provided. The four sets of protective pads 37 are fixed in sequence inside the four sets of guide holes, so that the corresponding wire roller body 310 can be installed according to the number of cable conductors 41 to be stranded, thereby improving the adaptability of the device.

[0026] A type of non-linear stranded conductor power cable includes a non-linear stranded conductor power cable stranding processing device as described above, and a cable conductor 41. The cable conductor 41 is disposed on a roller body 310. An insulation layer 42 is fixedly connected to the outside of the cable conductor 41. A first wrapping tape 44 is wrapped around the outside of the insulation layer 42. A filler layer 43 is disposed between the first wrapping tape 44 and the insulation layer 42. An inner sheath 45 is wrapped around the outside of the first wrapping tape 44. A second wrapping tape 47 is wrapped around the outside of the inner sheath 45. A non-magnetic metal wire armor layer 46 is disposed between the inner sheath 45 and the second wrapping tape 47. An outer sheath 48 is wrapped around the outside of the second wrapping tape 47. The inner sheath 45 is extruded from polyethylene sheath material to prevent external forces from damaging the cable conductor 41. The non-magnetic metal wire armor layer 46 is made of aluminum wire, which increases the cable current carrying capacity, reduces eddy current loss, ensures the normal operation of the cable, and improves the safety performance of the cable.

[0027] During operation, by moving the lever 24 to the right, the locking block 27 is moved away from the slot of the insertion rod 21, compressing the spring 26 and releasing the restriction on the insertion rod 21. The lever 22 then pulls the insertion rod 21 out from the U-shaped seat 39 and the roller body 310, facilitating replacement of the roller body 310. When installing the roller body 310, the through hole of the roller body 310 is aligned with the through hole of the U-shaped seat 39, aligning and inserting the insertion rod 21. When the lever 22 contacts the U-shaped seat 39, the lever 24 is released. At this point, the compressed spring 26, through its own elasticity, engages the locking block 27 in the annular groove of the insertion rod 21, limiting the insertion rod 21 so that it can only rotate, thus completing the replacement of the roller body 310 and improving the convenience of replacement. When stranding the cable conductor 41, the end of the cable conductor 41 is threaded through the guide... The cable conductor 41 is twisted together by passing through the guide hole of the frame 36, then through the stranding cylinder 5 and the wrapping unit 6 to connect with the external take-up roller. Then, by starting the motor 31, it drives the large gear 32 to rotate. The large gear 32 and the small gear 33 mesh with each other, causing the fixed frame 38 and the guide frame 36 to rotate together, thereby twisting the cable conductor 41 together. The protective pad 37 prevents damage to the cable conductor 41 during twisting, thereby improving the twisting efficiency of the cable conductor 41 and improving the practicality of the device. The twisted cable conductor 41 is then processed into a finished product by the wrapping unit 6. The inner sheath 45 is made of polyethylene sheath material to prevent external force from damaging the cable conductor 41. The non-magnetic metal wire armor layer 46 is made of aluminum wire, which increases the current carrying capacity of the cable, reduces eddy current loss, ensures the normal operation of the cable, and improves the safety performance of the cable.

[0028] Through the above steps, the insert rod 21 is pulled out from the U-shaped seat 39 and the wire roller body 310 by the lever 22, making it convenient to replace the wire roller body 310. The wire roller body 310 is aligned and inserted into the through hole of the U-shaped seat 39, and the insert rod 21 is limited by the locking block 27, so that the insert rod 21 can only rotate, thus completing the replacement of the wire roller body 310. This improves the convenience of replacing the wire roller body 310 and solves the problem that the operator must first remove the nuts used for precise positioning of the wire roller one by one, and then take out the exhausted or replaced wire roller from the device and replace it with a new wire roller, resulting in low efficiency of wire roller replacement and reduced efficiency of cable stranding processing.

[0029] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this utility model.
