Description

Technical Field

[0001] This utility model relates to the field of cable stranding machine technology, and in particular to an overhead cable stranding machine. Background Technology

[0002] As a crucial carrier in power transmission and communication engineering, overhead cables are exposed to the outdoor environment for extended periods, enduring the effects of wind, rain, temperature differences, and ultraviolet radiation. Therefore, the requirements for structural stability, tensile strength, and insulation performance of these cables are extremely high. Traditional stranding machines generally suffer from problems such as fixed wire spacing, low guiding accuracy, and large transmission errors. This results in overhead cables that are prone to defects such as loose stranding, uneven tension, and specification deviations, making it difficult to meet the demands of long-term outdoor use. Simultaneously, with the rapid development of the power and communication industries, the demand for overhead cables continues to grow, and the specifications and models are becoming increasingly diverse. The poor adaptability and low production efficiency of traditional stranding machines are becoming increasingly prominent. There is an urgent need for a dedicated stranding machine that can adapt to multiple cable specifications, provide precise stranding, and is easy to operate, in order to meet the needs of large-scale, high-quality overhead cable production.

[0003] To meet the above requirements, the cable laying spacing must be adjustable to accommodate the stranding needs of cables with different diameters and quantities, satisfying the production of various specifications of overhead cables and avoiding frequent equipment or component replacements. Precision requirements include ensuring uniform cable tension during laying and precise guidance during stranding to reduce cable deviation and loose stranding, guaranteeing a compact overhead cable structure with uniform specifications, and meeting the structural strength requirements for outdoor use. Efficiency requirements include a precise and reliable transmission structure supporting continuous and stable operation, reducing downtime for adjustments, improving production efficiency, and meeting the needs of large-scale production. Safety and convenience requirements include a simple and easy-to-understand operating procedure with safety protection structures to prevent operators from accidentally touching dangerous parts, while facilitating daily maintenance and component replacement to reduce usage and maintenance costs. Durability requirements include core components with anti-interference and wear-resistant properties to adapt to long-term continuous production environments, extending the equipment's lifespan and reducing equipment investment costs.

[0004] Therefore, we propose an overhead cable stranding machine. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an overhead cable stranding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An overhead cable stranding machine includes a base, which is inverted U-shaped. A control switch is installed on one side of the base. Two fixing rods are fixedly installed on the upper surface of the base. A crossbar is fixedly installed on one side of the top of each fixing rod. A guide assembly is installed on the upper surface of the crossbar. Two Geneva wheels are movably installed on the upper surface of the base. A stranding assembly is installed on the upper surface of each Geneva wheel. The stranding assembly includes a bracket. A bracket, which is U-shaped, is fixedly installed on the lower surface of the base. A motor is fixedly installed on the lower surface of the bracket. The motor is electrically connected to the control switch. A gear is installed inside the bracket. The lower surface of the gear is fixedly connected to the output end of the motor. A driven wheel is meshed with one side of the gear.

[0007] As a further embodiment of this utility model: the gear and the driven wheel are fixedly connected to two Geneva wheels respectively through a rotating shaft; a sliding groove is provided on the upper surface of the base; the sliding groove is V-shaped; three movable seats are engaged with the two Geneva wheels; three sliding blocks are rotatably connected to the lower surface of the three movable seats through a rotating shaft; and the three sliding blocks are slidably connected to the sliding groove.

[0008] As a further embodiment of this utility model: three limiting rods are fixedly installed on the upper surface of the three movable seats, a spool is movably installed on the outside of the three limiting rods, and bolts are threadedly connected to the top of the three limiting rods.

[0009] As a further embodiment of this utility model: the guide assembly includes a bracket, the lower surface of the crossbar is fixedly mounted with the bracket, the bracket is L-shaped, and the bottom end of the bracket away from the crossbar is fixedly mounted with a guide ring, the guide ring being semi-circular.

[0010] As a further embodiment of this utility model: a fixing plate is fixedly installed on the upper surface of the crossbar, there are two fixing plates, and guide wheels are rotatably connected to the two fixing plates on the side close to each other, there are two guide wheels, and the two guide wheels are set at different heights.

[0011] Compared with the prior art, this utility model provides an overhead cable stranding machine, which has the following advantages: This invention achieves stable and controllable operation throughout the entire process of wire laying, stranding, and guiding. The base adopts an inverted U-shaped design, which not only ensures the overall stability of the device but also provides installation space for the motor and transmission components below. Two Geneva wheels, in conjunction with a figure-eight sliding groove, drive three movable seats to move synchronously and crosswise for stranding. At the same time, the limiting rod on the movable seat, in conjunction with the top bolt, can limit the position of the wire drum, preventing uneven cable tension caused by the drum shaking during the laying process. The semi-circular guide ring in the guiding component and the two guide wheels set at different heights form a double guiding structure, which can accurately guide and adjust the tension of the cable during the stranding process, ensuring that the final stranded overhead cable structure is tight and the specifications are uniform, greatly improving product quality and production efficiency.

[0012] This invention features a transmission system employing a motor-driven gear mechanism. Through gear meshing with a driven wheel, two Geneva wheels rotate synchronously in opposite directions. The precise transmission ratio ensures smooth and orderly movement of the three movable seats, preventing cable twisting deviation due to transmission errors. The motor is electrically connected to a control switch, allowing operators to easily control the motor's start / stop and speed, thereby adjusting the twisting speed to accommodate different cable materials and reducing operational complexity. Furthermore, a U-shaped bracket encapsulates the motor, gears, and driven wheel, protecting the transmission components from external dust and impurities, extending their lifespan, and preventing accidental contact with rotating parts, thus enhancing safety. The overall structure is rationally laid out, with tight connections between components. Standardized control is achieved throughout the entire process from transmission and cable laying to guidance, meeting the continuous operation requirements of large-scale overhead cable production, reducing downtime for adjustments, and improving overall production efficiency.

[0013] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0018] Example: An overhead cable stranding machine, such as Figures 1-4As shown, the system includes a base 1, which is U-shaped. A control switch 2 is installed on one side of the base 1. Two fixing rods 3 are fixedly installed on the upper surface of the base 1. A crossbar 4 is fixedly installed on one side of the top of each fixing rod 3. A guide assembly 16 is installed on the upper surface of the crossbar 4. Two Geneva wheels 5 are movably installed on the upper surface of the base 1. A stranded wire assembly 6 is installed on the upper surface of each Geneva wheel 5. The stranded wire assembly 6 includes a bracket 7. A bracket 7 is fixedly installed on the lower surface of the base 1. The bracket 7 is U-shaped. A motor 8 is fixedly installed on the lower surface of the bracket 7. The motor 8 is electrically connected to the control switch 2. A gear 9 is installed inside the bracket 7. The lower surface of the gear 9 is fixedly connected to the output end of the motor 8. A driven wheel 10 is meshed with one side of the gear 9. The gear 9 and the driven wheel 10 are fixedly connected to the two Geneva wheels 5 respectively through a rotating shaft. A sliding groove 21 is formed on the upper surface of the base 1. The sliding groove 21 is V-shaped. The Geneva wheel 5 has three movable seats 11 internally engaged. The lower surfaces of the three movable seats 11 are rotatably connected to three sliding blocks 12 via a rotating shaft. The three sliding blocks 12 are slidably connected to a sliding groove 21. Three limiting rods 13 are fixedly installed on the upper surfaces of the three movable seats 11. A spool 14 is movably installed on the outside of the three limiting rods 13. Bolts 15 are threaded to the top of the three limiting rods 13. The device is connected to a factory power supply. First, according to the specifications of the cable to be stranded, the spool 14 is then fitted onto... On the limit rod 13, the fixed spool 14 is limited by bolts 15 to prevent the spool 14 from shaking up and down when the wire is unloaded; the motor 8 is started by the control switch 2. The motor 8 is a commercially available product. The output end of the motor 8 drives the gear 9 to rotate. The gear 9 meshes with the driven wheel 10 to make the two Geneva wheels 5 rotate synchronously in opposite directions; during the rotation of the Geneva wheel 5, the three movable seats 11 inside it slide along the figure-eight groove 21 with the sliding block 12 on the lower surface, thereby causing the three movable seats 11 to move crosswise to twist the cable.

[0019] like Figures 1-3 As shown, the guide assembly 16 includes a bracket 17. The bracket 17 is fixedly installed on the lower surface of the crossbar 4. The bracket 17 is L-shaped. A guide ring 18 is fixedly installed at the bottom end of the bracket 17 away from the crossbar 4. The guide ring 18 is semi-circular. A fixing plate 19 is fixedly installed on the upper surface of the crossbar 4. There are two fixing plates 19. The two fixing plates 19 are rotatably connected to guide wheels 20 on one side close to each other. There are two guide wheels 20. The two guide wheels 20 are set at different heights. The stranded wire is led out and passes through the semi-circular guide ring 18 in sequence, and then passes around the two guide wheels 20 set at different heights. Through the dual guidance of the guide wheels 20 and the guide ring 18, the cable maintains stable tension and is transported in the stranding direction.

[0020] Working principle: When in use, the device is connected to the factory power supply. First, according to the specifications of the cable to be stranded, the spool 14 is placed on the limiting rod 13, and the spool 14 is fixed with bolts 15 to prevent it from shaking up and down during cable unwinding. The motor 8 is started by the control switch 2. The motor 8 is a commercially available product. The output end of the motor 8 drives the gear 9 to rotate. The gear 9 meshes with the driven wheel 10, causing the two Geneva wheels 5 to rotate synchronously in opposite directions. During the rotation of the Geneva wheels 5, the three movable seats 11 inside them move in a figure-eight pattern along the sliding block 12 on their lower surface. The slid groove 21 slides, causing the three movable seats 11 to move crosswise to twist the cable. Then, the twisted cable is led out and passes through the semi-circular guide ring 18 in sequence, and then around the two guide wheels 20 set at different heights. Through the dual guidance of the guide wheels 20 and the guide ring 18, the cable maintains stable tension and is conveyed in the twisting direction. Finally, the speed of the motor 8 is adjusted according to production needs, and the rotation speed of the Geneva wheel 5 and the stability of the distance between the movable seats 11 are controlled to ensure that the cable is twisted evenly during the conveying process, forming an overhead cable that meets the specifications, and completing the twisting operation.
