Description

Technical Field

[0001] This utility model relates to the field of power construction equipment technology, specifically to an insulated wire laying frame. Background Technology

[0002] Insulated wires are widely used in power transmission, electrical equipment installation, and various fields involving the use of conductors. As a type of conductor with an insulating layer, insulated wires can effectively prevent current leakage, ensure personnel safety and normal equipment operation, and are an indispensable basic material in various engineering projects. In actual operation, it is necessary to smoothly release the insulated wires from the coil and reasonably transport them to the designated location. This process requires the use of a wire release frame to achieve efficient and orderly wire release operations, so as to meet the needs of conductor use in different construction scenarios and improve construction efficiency.

[0003] Traditional insulated wire laying frames have many drawbacks in practical applications. On the one hand, the structural design of traditional laying frames is often relatively simple, lacking effective control of tension during the laying process. During laying, the rotation speed of the wire reel is difficult to adjust precisely, resulting in uneven tension when the wire is laid out. This not only causes problems such as tearing and deformation on the surface of the wire, affecting the insulation performance and mechanical strength of the wire, but may also create safety hazards in subsequent use. On the other hand, the height of traditional laying frames is usually fixed and cannot be adjusted, making it impossible to adapt to the height requirements of different construction sites and the laying needs of wire reels of different specifications. This makes laying operations extremely inconvenient in some special construction environments, seriously reducing construction efficiency, increasing construction costs, and restricting the development of related industries. To address these issues, we have proposed an insulated wire laying frame. Utility Model Content

[0026] Furthermore, the rotating structure includes a bearing housing 10, a second mounting plate 11, a rotating shaft 12, a second bearing housing 13, and a wire coil 14. The second mounting plate 11 is fixedly mounted on the side of the first mounting plate 2. The first bearing housing 10 is fixedly mounted on the side of the second mounting plate 11. The rotating shaft 12 is rotatably mounted inside the first bearing housing 10.

The bottom of the second bearing housing 13 is fixedly mounted on the support frame 1. The wire coil 14 is fixedly mounted on the outer surface of the rotating shaft 12. The second mounting plate 11 in the rotating structure... While fixing the bearing housing 10, it also provides a stable mounting base for the entire rotating structure, ensuring the installation accuracy of the shaft 12 and preventing axial or radial offset during rotation. Both bearing housing 10 and bearing housing 13 are equipped with high-precision balls or rollers. These rolling elements can greatly reduce the frictional resistance of the shaft 12 during rotation, improve rotational efficiency, and reduce energy loss.

A guide rod 21 is slidably installed in the top groove of the lifting plate 20. A guide groove is opened on the side of the guide rod 21. The guide groove of the guide rod 21 cooperates with the wire coil 14. The telescopic cylinder 16 in the lifting structure is made of high-strength alloy material to ensure that it will not deform or crack during frequent extension and retraction. To ensure the reliability of the lifting action, the telescopic cylinder 16 is also equipped with an overload protection device. When the weight borne by the lifting plate 20 exceeds its rated load, the telescopic action will automatically stop to avoid damage to the cylinder. The surface of the guide rod 21 is specially treated with wear resistance to reduce the coefficient of friction between it and the sliding groove of the lifting plate 20, making the lifting process smoother and also increasing the service life of the guide rod 21.

[0028] Furthermore, the sliding structure includes sliding bushings 18 and sliding shafts 19. Multiple sets of equidistantly distributed sliding bushings 18 are fixedly installed on the support plate 17. Sliding shafts 19 are slidably installed inside the sliding bushings 18. The top of the sliding shafts 19 is fixedly connected to the lifting plate 20. The inner surface of the sliding bushings 18 in the sliding structure is coated with high-performance grease to further reduce the friction between the sliding shafts 19 and the sliding bushings 18, reduce wear, and also play a certain role in rust prevention. The sliding shafts 19 are made of high-quality carbon steel and have undergone quenching and tempering treatment to improve their hardness and strength, so that they will not bend or deform when bearing the weight of the lifting plate 20 and various external forces, ensuring the stability of the lifting structure. Multiple sets of sliding bushings 18 and sliding shafts 19 are evenly distributed on the support plate 17. This layout allows the lifting plate 20 to be subjected to more uniform force during the lifting process, avoiding tilting, shaking, etc., and ensuring the smooth operation of the entire line feeding process.

The operator can adjust the distance between the two support rods 22 according to the actual wire feeding needs to adapt to wire rolls of different widths. The surface of the auxiliary roller 23 is made of highly elastic and wear-resistant rubber material, which can effectively reduce the friction between the wire and the auxiliary roller 23, and provide sufficient friction to prevent the wire from slipping on the auxiliary roller 23. Bearings are also installed at both ends of the auxiliary roller 23 so that it can rotate flexibly, further reducing the resistance of the wire when passing through, ensuring that the wire can pass through the auxiliary structure smoothly during the wire feeding process, and reducing wire damage caused by friction and jamming.

[0054] Working Principle: The core of the device's power control is the control structure, which consists of a motor housing 5, control buttons 6, a display screen 7, and a motor 8. The operator sends commands to the motor 8 via control button 6. The motor 8 is installed inside the motor housing 5, its bottom firmly fixed to the first mounting plate 2. Its output shaft is connected to connector 9. After the motor 8 starts, it converts electrical energy into mechanical energy, driving connector 9 to rotate, thereby precisely controlling the rotation speed of the rotating structure. The display screen 7 provides real-time feedback on the motor 8's operating parameters, such as speed and operating time, facilitating monitoring and adjustment by the operator. This ensures that the conductor tension remains within a suitable range during the wire feeding process, preventing damage or deformation due to uneven tension, and guaranteeing the quality and performance of the conductor. The rotating structure includes a bearing housing 1. 0. The second mounting plate 11, rotating shaft 12, bearing seat 2 13, and wire reel 14 are connected by connector 9. The rotating shaft 12 rotates smoothly within bearing seat 1 10 and bearing seat 2 13. The wire reel 14, fixed to the outer surface of the rotating shaft 12, rotates synchronously. Bearing seat 1 10 and bearing seat 2 13 provide stable support for the rotating shaft 12, reducing rotational friction and making the rotation of the wire reel 14 smoother. This ensures that the wire can be released from the wire reel 14 at a uniform speed and stably, meeting the requirements of different construction scenarios for wire release speed and stability. The lifting structure consists of telescopic cylinder 16, lifting plate 20, and guide rod 21. When the telescopic cylinder 16 on the cylinder fixing plate 15 is working, the piston rod extends and retracts, driving the lifting plate 20 to move up and down along the support plate 17. The sliding groove at the top of the lifting plate 20 and the guide rod 21 are connected. 1. The guide groove on the side of the guide rod 21 works in conjunction with the wire reel 14 to ensure stable and precise lifting of the lifting plate 20. This structure allows for flexible adjustment of the laying height according to the height requirements of the construction site and the specifications of the wire reel 14, adapting to different construction environments. For example, when laying power lines in mountainous or other complex terrain areas, the laying frame can be easily adjusted to a suitable height, improving construction efficiency and avoiding difficulties and safety hazards caused by unsuitable height. The sliding structure includes a sliding bushing 18 and a sliding shaft 19. Multiple sets of equidistantly distributed sliding bushings 18 are fixed on the support plate 17. The sliding shaft 19 is installed inside the sliding bushing 18 and its top is connected to the lifting plate 20. During the lifting process of the lifting plate 20, the sliding shaft 19 slides within the sliding bushing 18, thus... The auxiliary support rods 22 and 23 are installed on the side of the support frame 1 to provide auxiliary support and guidance, enhance the stability of the lifting structure, prevent the lifting plate 20 from shifting or swaying during movement, and ensure the smooth progress of the entire wire laying process. During wire laying, the wire passes through the auxiliary rollers 23, which reduce friction between the wire and other components and guide the wire to be laid out smoothly in the correct direction. This not only reduces wear on the wire surface but also effectively avoids problems such as tangling and jamming during the wire laying process, further ensuring the smoothness of the laying, improving construction efficiency, and reducing the number of construction interruptions caused by wire failures. In actual operation, the operator first starts the motor 8 and adjusts its speed using the control button 6 according to the construction requirements.Motor 8 drives the rotating structure to rotate the wire reel 14 for wire feeding. Simultaneously, if the feeding height needs adjustment, the telescopic cylinder 16 can be activated to raise or lower the lifting plate 20. A sliding structure ensures stability during the raising and lowering process. Throughout the feeding process, the auxiliary roller 23 of the auxiliary structure continuously plays a role in reducing conductor friction and guiding the conductor, ultimately achieving efficient, orderly, and stable insulated wire feeding operations, meeting the requirements of various construction scenarios for insulated wire feeding.
