Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment technology, specifically to an improved overhead insulated conductor stranding device for a tube stranding machine. Background Technology

[0002] Overhead cables (full name: overhead insulated cables) are overhead conductors equipped with insulation layers and protective sheaths. They are specialized cables manufactured using a process similar to that of cross-linked cables, representing a new power transmission method between overhead conductors and underground cables. Overhead cables are all single-core and, based on their structure, can be classified into hard aluminum wire structure, hard-drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core supported structure, and self-supporting three-core composite structure (the core can be hard aluminum or hard copper wire), etc. They are characterized by high power supply reliability, good power supply safety, convenient installation and maintenance, and reasonable economic efficiency. Their main technical parameters include weather resistance, insulation level, and inner and outer semi-conductive shielding layers. Overhead cables are widely used in power transmission both domestically and internationally.

[0003] Chinese Patent CN222813361U discloses an aluminum alloy conductor stranding and tensioning device, relating to the field of aluminum alloy conductor technology. It includes a base plate, on which a feeding mechanism, a fixing frame, a traction mechanism, a support frame, and a winding mechanism are mounted. The feeding mechanism is equipped with a wire distributor and an adjustment unit. The fixing frame is equipped with a stranding mechanism, and the support frame is equipped with an anti-derailment unit. The beneficial effect lies in using a visual inspection mechanism to judge the tension of the conductor before stranding. The position of the first ring on the transmission rod is adjusted by a first telescopic mechanism, a guide ring, and a trapezoidal slider. The first ring adjusts the inclination of one end of the transmission rod, thereby adjusting the position of the mounting seat and the second ring at the other end of the transmission rod. This allows the second ring to tension the conductor before stranding, adjusting the conductor's state, increasing the tension of the stranded conductor, and enabling better stranding, thus ensuring the quality of the stranding.

[0004] In the related technology, the improved overhead insulated conductor stranding device of the tube stranding machine cannot control and adjust the speed of the winch and the traction speed in real time according to the actual production situation. This results in unstable stranding pitch of the stranded conductor, which affects the electrical performance and strength of the conductor. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-3 As shown, it illustrates an improved overhead insulated conductor stranding device for a tube stranding machine according to an embodiment of the present invention, including a base 1, a auger 4 fixed on one side of the top of the base 1, a take-up reel 5 fixed on the other side of the top of the base 1, an adjustment component 2 fixed on the side of the auger 4, and a tension component 3 installed on the side of the auger 4 near the take-up reel 5.

[0031] Adjustment assembly 2 includes a motor 21, with a rotating shaft 22 fixed to the output end of the motor 21. A driving bevel gear 23 is fixed to the outside of the rotating shaft 22. A driven bevel gear 24 is meshed with the side of the driving bevel gear 23. A connecting gear 25 is fixed to the other end of the driven bevel gear 24. A toothed belt 26 is sleeved on the outside of the connecting gear 25. A driven gear 27 is meshed with the side of the toothed belt 26 away from the connecting gear 25. A driving eccentric wheel 28 is fixed to the other end of the driven gear 27. A protrusion 210 is fixed on the outer side, and a connecting rod 211 is rotatably connected to the protrusion 210. The other end of the connecting rod 211 is rotatably connected to a driven eccentric wheel 212. The driven eccentric wheel 212 is rotatably connected to the side of the take-up reel 5. The diameters of the driving bevel gear 23 and the driven bevel gear 24 are the same, and the diameters of the driving eccentric wheel 28 and the driven eccentric wheel 212 are the same. This can prevent speed errors when transmitting the rotational speed of the winch 4 and adjusting the rotational speed of the take-up reel 5 accordingly.

[0032] In some examples, a support column 29 is fixed to the top of the base 1, and a connecting gear 25 is rotatably connected to the side of the support column 29. A driven gear 27 and a driving eccentric wheel 28 are rotatably connected in the support column 29. The diameter of the connecting gear 25 and the driven gear 27 are the same. The support column 29 can support the connecting gear 25, so that the connecting gear 25 can transmit the rotational speed of the driving bevel gear 23 and the driven bevel gear 24 to the driving eccentric wheel 28, so that the rotational speed of the take-up reel 5 can be adjusted according to the rotational speed of the winch 4.

[0033] In some examples, the winch 4 is fixed to the other end of the rotating shaft 22, so that the rotation speed of the winch 4 can be synchronized with the drive bevel gear 23 on the rotating shaft 22, thereby adjusting the rotation speed of the take-up reel 5 and achieving precise control of the twisting pitch.

[0034] In some examples, a twisting post 213 is fixed to the top of the base 1, and the twisting post 213 is fixed between the winding cage 4 and the take-up reel 5. A twisting groove 214 is formed in the twisting post 213. A laser displacement sensor 215 is fixed to the top of the twisting groove 214. A tightening ring 216 is fixed to the side of the twisting groove 214 near the winding cage 4, and a conical ring 217 is fixed to the side of the twisting groove 214 away from the tightening ring 216. A first cylinder 218 is fixed to the inner wall of the twisting groove 214, and the other end of the first cylinder 218... A clamping block 219 is fixed in place. The laser displacement sensor 215 is an SG5080 type sensor used to monitor the change in stranding pitch in real time, thereby controlling the speed of the motor 21 to adjust the speed according to actual needs. The conical ring 217 is made of malleable material. The tightening ring 216 can make the wire fit the conductor better. The first cylinder 218 pushes the clamping block 219 to press the conical ring 217 against the conductor, making the stranded conductor more compact.

[0035] In some examples, the tightening ring 216 has the same number of holes as the wires, so that multiple sets of wires can be tightly wrapped around the conductor through the tightening ring 216, which facilitates subsequent clamping operations.

[0036] For example, such as Figure 2As shown, when the rotation speed of the winch 4 and the take-up reel 5 needs to be adjusted according to actual production requirements, the rotation speed of the motor 21 can first be adjusted by controlling the PLC. This causes the driving bevel gear 23 on the rotating shaft 22 at the output end of the motor 21 to mesh with the driven bevel gear 24 on the side. This allows the connecting gear 25 at the other end of the driven bevel gear 24 to transmit the rotational speed to the driven gear 27 via the toothed belt 26, causing the driving eccentric wheel 28 at the other end of the driven gear 27 to rotate. During the rotation, the connecting rod 211 rotates on the protrusion 210 on the side of the driving eccentric wheel 28, causing the other driven eccentric wheel 28 on the connecting rod 211 to rotate. 12 drives the take-up reel 5 at the same rotational speed to adjust the twisting pitch. The adjusted twisting pitch is monitored by the laser displacement sensor 215. When the appropriate pitch is reached, the speed adjustment of the motor 21 is stopped by the PLC. When the wire is wrapped around the conductor by the tightening ring 216, before the conductor passes through the conical ring 217, the first cylinder 218 is controlled by the PLC to push the clamping block 219, so that the diameter of the conical ring 217 changes to be smaller than the diameter of the conductor and the wire. Then, when the conductor passes through the conical ring 217, the conductor can be clamped, so that the twisted conductor has a higher tightness.

[0037] like Figures 4-5 As shown, this invention illustrates an improved overhead insulated conductor stranding device for a tube stranding machine in another embodiment of the present invention. The tension assembly 3 includes a second cylinder 31, which is fixed to the side of the winch 4. An adjusting disc 32 is fixed to the other end of the second cylinder 31, and a support block 34 is fixed to the other end of the adjusting disc 32. A pulley 35 is rotatably connected to the support block 34. A tension sensor 36 is fixed to the side of the pulley 35. The tension sensor 36 is a ZHZL-XB type sensor used to detect the tension generated when the conductor passes through the pulley 35, thereby corresponding to the position of the adjusting disc 32 via the PLC control console for tension adjustment.

[0038] In some examples, the adjusting plate 32 has an adjusting groove 33 located directly above the pulley 35. After the wire passes through the adjusting groove 33, it slides in the groove of the pulley 35, so that the real-time tension of the wire in the adjusting groove 33 can be detected.

[0039] In some examples, a guide rod 38 is fixed to the side of the winch 4, and a positioning groove 37 is provided in the adjustment plate 32. The positioning groove 37 slides on the guide rod 38, and the guide rod 38 can support the adjustment plate 32, thereby preventing the adjustment plate 32 from tilting due to gravity after long-term use, which would result in different tensions of the detected wires.

[0040] For example, such as Figure 4As shown, when the winch 4 is working, the wire is twisted with the conductor through the adjustment groove 33 in the adjustment disc 32. The wire tension can be adjusted according to the actual production requirements. When the wire slides through the pulley 35, the tension sensor 36 on the side of the pulley 35 detects the wire tension in real time. Then, the PLC controls the second cylinder 31 to push or retract the adjustment disc 32. When the adjustment disc 32 is pushed to one side of the winch 4, the wire tension increases, thereby reducing the gap between the wires and making the wire arrangement neater.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
