Description

Technical Field

[0001] This utility model belongs to the field of power engineering technology, and in particular relates to a stringing device for power transmission line construction. Background Technology

[0002] Transmission line construction refers to the comprehensive engineering process of safely, efficiently, and stably transmitting electrical energy generated by power plants to various power-consuming areas through a series of carefully planned lines and equipment. Line stringing is one of the most crucial and core aspects of transmission line construction. Its main task is to accurately and flawlessly erect conductors, lightning protection wires, and other components onto the pre-assembled poles and towers according to design requirements, thereby constructing a complete power transmission channel.

[0003] Traditional overhead power line installation often uses a combination of aerial deployment and tension traction. During installation, drones, airships, or manpower are used to deploy guide ropes between various poles. Then, traction equipment is used to pull the conductors to the designated positions step by step. To ensure construction quality and safety, a tensioning machine is used to apply appropriate tension to the conductors, keeping them suspended in the air to prevent wear, damage, or contamination from contact with the ground. However, in practice, this traditional method requires multiple workers to coordinate at different locations, making coordination between stages difficult. Poor communication, asynchronous operations, or human error can easily lead to construction delays and even safety hazards.

[0004] Therefore, it is necessary to design a stringing device for power transmission line construction to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional stringing methods, such as the difficulty of coordination among multiple people and multiple stages, and the potential for construction delays and safety hazards due to communication and operational problems, this utility model provides a stringing device for power transmission line construction.

[0006] This utility model is achieved through the following technical means: a stringing device for power transmission line construction, comprising a frame, wheels, axles, a controller, a motor, a pulley assembly, a pressure roller, an electric slide rail, an electric slider, a conductor wheel, a bracket, a cable reel, a fixing component, and a locking component. Two axles are arranged side by side and rotatably mounted on the lower part of the frame. Each axle has a wheel installed at both its front and rear ends. The controller is mounted on one side of the upper part of the frame, and the motor is also mounted on one side of the upper part of the frame, with its output shaft extending rearward. The motor is electrically connected to the controller. The pulley assembly is located between the output shaft of the motor and one of the axles. The pressure roller is rotatably mounted on the other side of the upper part of the frame. The electric slide rail is mounted on the top of the frame, and an electric slider is slidably mounted on the electric slide rail. Both the electric slide rail and the electric slider are electrically connected to the controller. The conductor wheel is rotatably mounted on one side of the electric slider. The bracket is mounted on one side of the upper part of the frame. The cable reel is rotatably mounted on the upper part of the bracket. The fixing component is mounted on the cable reel, and the locking component is located between the bracket and the cable reel.

[0007] Furthermore, the fixing assembly includes a knob, a nut, a top block, a screw, and support rods. The knob is sleeved on one end of the cable reel. The screw is rotatably disposed inside the cable reel, with one end extending to the outside of the cable reel. The nut is fixed to one end of the screw and inserted into the knob. The top block is threaded on the outside of the screw and is located inside the cable reel, where it slides. Two support rods are vertically distributed and slidably disposed on the cable reel. The running trajectory of the top block intersects with the positions of the two support rods.

[0008] Furthermore, the locking assembly includes a ratchet, a rotating shaft, ratchet teeth, and a torsion spring. The ratchet is fixed to one end of the cable reel, the rotating shaft is rotatably mounted on the upper part of the bracket, the ratchet teeth are fixed to the outside of the rotating shaft, the tip of the ratchet is inserted into the tooth groove of the ratchet, and a torsion spring is sleeved on the outside of the rotating shaft. The two ends of the torsion spring are fixedly connected to the bracket and the rotating shaft, respectively.

[0009] Furthermore, the wheels feature a wide tread design.

[0010] Furthermore, the top block has a guide bevel at the end near the strut.

[0011] Furthermore, the side of the strut furthest from the screw is covered with a rubber pad.

[0012] Beneficial effects: 1. Through the coordinated work of wheels, axles, motors and pulleys, the device has autonomous movement capabilities and can efficiently complete the laying of conductors. At the same time, the linkage between the electric slide rails, electric sliders and conductor wheels enables precise control of the laying height and direction of the conductors, effectively replacing the traditional manual operation mode of multi-person, multi-point collaboration, reducing reliance on manual labor, improving construction efficiency and safety, and significantly reducing construction costs.

[0013] 2. By adopting a combination design of knob, nut, screw, top block and support rod, the operator only needs to rotate the knob to move the top block using the thread transmission principle, thereby driving the support rod to fix or loosen the spool. This design is simple in structure and easy to operate, and can quickly fix and disassemble the spool, improving construction efficiency.

[0014] 3. By using the ratchet and ratchet structure in the locking assembly, the position of the cable reel can be reliably locked during the movement of the device, preventing the cable reel from rotating accidentally and causing the wire to be released. When laying the wire, the ratchet and ratchet can automatically separate, allowing the cable reel to rotate normally and release the wire. This design ensures the safety of the movement process without affecting the smooth progress of the laying work. Attached Figure Description

[0023] Example: A stringing device for power transmission line construction, such as... Figures 1-7As shown, the system includes a frame 1, wheels 2, axles 201, a controller 3, a motor 4, a pulley assembly 5, a pressure roller 6, an electric slide rail 7, an electric slider 8, a guide wheel 9, a bracket 10, a cable reel 101, a fixing assembly, and a locking assembly. Two axles 201 are arranged side-by-side and rotatably mounted on the lower part of the frame 1. Each axle 201 has a wheel 2 bolted to its front and rear ends. The wheels 2 have a wide tread design, which makes the frame 1 more stable when traveling on complex terrain during power transmission line construction. The controller 3 is bolted to the upper right side of the frame 1, slightly forward, and the motor 4 is bolted to the upper right side of the frame 1, slightly rear. Its output shaft... Extending rearward, motor 4 is electrically connected to controller 3. Pulley assembly 5 is located between the output shaft of motor 4 and right axle 201. Pressure roller 6 is rotatably located on the upper left side of frame 1. Electric slide rail 7 is bolted to the top of frame 1. Electric slider 8 is slidably mounted on electric slide rail 7. Both electric slide rail 7 and electric slider 8 are electrically connected to controller 3. Wire wheel 9 is rotatably located in front of electric slider 8. Bracket 10 is bolted to the upper right rear position of frame 1. Cable reel 101 is rotatably located on the upper part of bracket 10. Fixing component is located on cable reel 101. Locking component is located between bracket 10 and cable reel 101.

[0024] like Figure 4 , Figure 5 and Figure 6 As shown, the fixing assembly includes a knob 11, a nut 12, a top block 13, a screw 14, and a support rod 15. The knob 11 is sleeved on the front end of the cable reel 101. The screw 14 is rotatably disposed inside the cable reel 101, with its front end extending to the outside of the cable reel 101. The nut 12 is fixedly connected to the front end of the screw 14 and is inserted into the knob 11. The nut 12 is a hexagonal nut. Based on the polygonal characteristics of a hexagon, the knob 11 can rotate to drive the nut 12 to rotate together, thereby driving the screw 14 to rotate. The top block 13 is threaded on the outside of the screw 14 and is located on the cable reel. The cable reel 101 is internally slidably fitted with two support rods 15, which are slidably arranged vertically on the cable reel 101. The running trajectory of the top block 13 intersects with the position of the two support rods 15, ensuring that when the top block 13 slides toward the support rods 15, it can lift the support rods 15. The rear end of the top block 13 near the support rods 15 is provided with a guide angle, which allows the top block 13 to better contact and squeeze the support rods 15 when it slides toward the support rods 15. The side of the support rod 15 away from the screw 14 is covered with a rubber pad. When the support rod 15 supports the wire wheel on the cable reel 101, the rubber pad can increase the friction and prevent the wire wheel from slipping.

[0025] like Figure 5 , Figure 6 and Figure 7As shown, the locking assembly includes a ratchet 16, a rotating shaft 161, a ratchet tooth 162, and a torsion spring 17. The ratchet 16 is fixedly connected to the rear end of the cable reel 101. The rotating shaft 161 is rotatably mounted on the upper part of the bracket 10. The ratchet tooth 162 is fixedly connected to the outside of the rotating shaft 161. The tip of the ratchet 16 is inserted into the tooth groove of the ratchet 16, thereby locking the angle of the cable reel 101 through the ratchet tooth 162. The torsion spring 17 is sleeved on the outside of the rotating shaft 161. The front and rear ends of the torsion spring 17 are fixedly connected to the bracket 10 and the rotating shaft 161, respectively, providing a reset spring force for the rotating shaft 161 and the ratchet tooth 162.

[0026] During the construction of power transmission line projects, the operators first conduct a comprehensive inspection of the equipment to ensure that all components are securely connected and operating normally. After the inspection is completed, the knob 11 is removed from the cable reel 101 to release the engagement between the knob 11 and the nut 12. Then, the reel is smoothly threaded onto the cable reel 101 to ensure that the reel is installed in place. Finally, the knob 11 is put back on to ensure that it is accurately engaged with the nut 12.

[0027] After the engagement is complete, rotate the knob 11 clockwise. The knob 11 drives the nut 12 to rotate clockwise as well. The nut 12 then drives the screw 14 to rotate clockwise as well. During the rotation, the screw 14 drives the top block 13 to move backward through the threaded transmission. The top block 13 gradually contacts and lifts the two support rods 15, causing the support rods 15 to move outward. As the support rods 15 move, they gradually approach the inner ring surface of the reel. As the top block 13 continues to move, the pressure of the support rods 15 on the inner ring surface of the reel gradually increases. When the top block 13 slides to the appropriate position, the support rods 15 are in close contact with the inner ring surface of the reel, and the operator feels a significant increase in resistance when rotating the knob 11, indicating that the reel has been firmly fixed to the cable reel 101.

[0028] Then, the motor 4 is started by the controller 3. The motor 4 transmits power to the right axle 201 through the pulley assembly 5. The right axle 201 drives the two right wheels 2 to rotate. Since the overall structure of the frame 1 is stable, the left and right wheels 2 are rigidly connected through the frame 1. When the right wheel 2 rotates, it drives the entire frame 1 to move, which in turn causes the two left wheels 2 to rotate as well. Together, they work together to move the entire device smoothly to the designated construction position.

[0029] During the movement, the locking component comes into play. The tip of the ratchet 162 is inserted into the tooth groove of the ratchet 16. The two work together to effectively lock the position of the cable reel 101, preventing the cable reel 101 from rotating accidentally due to the vibration caused by the movement of the device, and preventing the cable reel from rotating to release the wire.

[0030] After reaching the designated position, the electric slide rail 7 is started by the controller 3, and the electric slider 8 is controlled to slide down to the bottom of the electric slide rail 7. At this time, the wire on the wire wheel is pulled out and passed around the lower surface of the pressure roller 6 and the upper surface of the wire wheel 9 in sequence, so that the wire is guided by the pressure roller 6 and the wire wheel 9 to maintain the correct direction and is pulled to the right side of the device to prepare for subsequent laying.

[0031] After the preparation work is completed, control the electric slider 8 to slide upward to the appropriate position of the electric slide rail 7, so that the wire is at the appropriate laying height. Then restart the motor 4, and the drive device continues to move to start the wire laying work. During laying, the wire is pulled out smoothly from the wire wheel. The wire wheel is pulled by the wire and drives the cable reel 101 to rotate counterclockwise (counterclockwise rotation with the front end of the cable reel 101 as the reference direction). The ratchet 16 rotates counterclockwise with the cable reel 101. During the rotation, the tooth surface of the ratchet 16 presses the tip of the ratchet 162, causing the ratchet 162 to automatically disengage from its tooth groove. The torsion spring 17 deforms accordingly, thereby allowing the wire wheel and cable reel 101 to rotate normally and smoothly release the wire.

[0032] After laying is complete, turn off motor 4 to stop the device from moving. Then, rotate knob 11 counterclockwise. Knob 11 will rotate nut 12 counterclockwise, which in turn will rotate screw 14 counterclockwise. Driven by screw 14, top block 13 moves forward and gradually disengages from the two support rods 15. Support rod 15 is no longer subject to the force of top block 13, and its fixing effect on the reel disappears. At this point, pull out knob 11 again to easily remove the used reel. If you need to continue laying wires, simply replace the reel with a new one and repeat the above steps.
