Description

Technical Field

[0001] This utility model is a foreign object removal device for power transmission lines, belonging to the field of power transmission line maintenance. Background Technology

[0002] Timely removal of foreign objects from power transmission lines is crucial to prevent short circuits or power outages caused by these obstructions. Compared to traditional manual methods, robots can complete the task quickly and efficiently, reducing power outage maintenance time. Wheeled power transmission line foreign object removal robots are common equipment. The support rollers and pressure rollers in these robots move along the power transmission line under the action of servo motors. When the robot encounters vibration dampers or intermediate bars, its electric grippers clamp onto the power line, facilitating the separation of the pressure rollers and support rollers from the line. This allows the robot to pass over the vibration dampers and intermediate bars. However, vibration dampers vary in length, while the relative position of the electric grippers within the robot is fixed. For wider vibration dampers, the robot cannot easily pass over longer ones, hindering the removal of foreign objects from the power transmission line. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foreign object removal device for power transmission lines to solve the problems mentioned in the background art. This utility model realizes the adjustment of the spacing between the cooperating electric grippers, which makes it easier to pass over anti-vibration hammers of different lengths.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A foreign object removal device for power transmission lines includes an electrical control box. Two brackets arranged in a "V" shape are installed on the top of the electrical control box. A first servo motor is installed at the end of the bracket away from the electrical control box. A hollow arm is installed at the output end of the first servo motor. A second servo motor is installed at the upper end of the hollow arm. A carrier plate is installed at the upper end of the hollow arm (6). A third servo motor is installed at the end of the carrier plate away from the second servo motor. A support roller is installed on the output shaft of the third servo motor. An L-shaped arm is installed on the output shaft of the second servo motor. An arc-shaped groove is opened on one side of the carrier plate. A fourth servo motor is installed through the arc-shaped groove at the end of the L-shaped arm away from the second servo motor. A pressure roller is installed on the output shaft of the fourth servo motor. A support plate is installed on the outer surface of the bracket. Two sets of electric grippers are installed on the support plate through an adjusting component.

[0005] Furthermore, the adjusting component includes a movable seat, a strip groove is formed on the upper surface of the support plate, two movable seats are provided on the upper side of the strip groove, an electric gripper is installed on the upper surface of the movable seat by screws, a protrusion is connected and fixed on the lower surface of the movable seat, the protrusion passes through the strip groove, a through hole is formed on one side of the protrusion, a screw is inserted into the through hole, the end of the screw is connected to the support plate, the screw is arranged along the length direction of the strip groove, and adjusting nuts are provided on both sides of the protrusion, the adjusting nuts are threadedly connected to the screw.

[0006] Furthermore, a notch is provided on the lower surface of the protrusion, and the notch communicates with the through hole.

[0007] Furthermore, a connecting seat is installed at the bottom of the electric gripper, and the connecting seat is connected to the movable seat by screws.

[0008] Furthermore, two symmetrically arranged end ears are installed on the lower surface of the tray, the end of the screw passes through the end ears, and both ends of the screw are threaded with limit nuts. The two end ears on the tray are arranged between the two limit nuts on the corresponding screw.

[0009] Furthermore, one end of the carrier plate is equipped with a lug for connecting a cutting blade driven by a motor, and the lug and the carrier plate are integrally formed.

[0010] Furthermore, the protrusion and the movable seat are integrally formed, and the width of the protrusion is the same as the width of the strip groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. Control the second servo motor to work, so that the second servo motor drives the fourth servo motor to move along the arc groove through the L-shaped arm, so that the pressure roller presses on the transmission line. At this time, when the pressure roller and the support roller work together, the pressure roller and the support roller move along the transmission line. The cutting blade mounted on the carrier plate rotates under the drive of the motor, thereby cutting and removing plastic bags and other debris attached to the transmission line.

[0013] 2. When it is necessary to pass over the vibration damper and intermediate bar, the two electric grippers on the side closer to the vibration damper and intermediate bar shall not grip the transmission line, while the two electric grippers on the side farther away from the vibration damper and intermediate bar shall grip the transmission line. Then, control the first servo motor to rotate, so that the support roller moves to the side of the transmission line. After the support roller passes over the vibration damper and intermediate bar, the two electric grippers on the front side of the moving direction shall grip the transmission line, while the two electric grippers on the rear side of the moving direction shall not grip the transmission line, so as to smoothly pass over the vibration damper and intermediate bar.

[0014] 3. Adjust the position of the two movable seats on one pallet according to the length of the vibration damper. At this time, the distance between the two electric grippers on one pallet changes, and the relative position of the protrusion and the screw changes. When the distance between the two electric grippers on one pallet meets the requirement of passing the vibration damper, the relative position of the screw and the protrusion can be limited by adjusting the nut. This realizes the adjustment of the distance between the cooperating electric grippers, which is convenient for passing vibration dampers of different lengths. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a technical solution: a foreign object removal device for power transmission lines, including an electrical control box 1. Two "V"-shaped brackets 2 are mounted on the top of the electrical control box 1. A first servo motor 5 is mounted on the end of each bracket 2 away from the electrical control box 1. A hollow arm 6 is mounted on the output end of the first servo motor 5. A second servo motor 7 is mounted on the upper end of the hollow arm 6. A carrier plate 8 is mounted on the upper end of the hollow arm 6. A third servo motor 12 is mounted on the end of the carrier plate 8 away from the second servo motor 7. A support roller 11 is mounted on the output shaft of the third servo motor 12. An L-shaped arm 22 is mounted on the output shaft of the second servo motor 7. An arc-shaped groove 23 is formed on one side of the carrier plate 8. The L-shaped arm 22 is positioned away from the second servo motor 7. The fourth servo motor 9 is installed through the arc-shaped groove 23. The output shaft of the fourth servo motor 9 is equipped with a pressure roller 10. One end of the carrier plate 8 is equipped with a lug seat 24 for connecting the cutting blade driven by the motor. The lug seat 24 and the carrier plate 8 are integrally formed. The second servo motor 7 is controlled to work. Thus, the second servo motor 7 drives the fourth servo motor 9 to move along the arc-shaped groove 23 through the L-shaped arm 22, so that the pressure roller 10 presses on the transmission line. At this time, when the pressure roller 10 and the support roller 11 cooperate with each other and the fourth servo motor 9 works, the pressure roller 10 and the support roller 11 move along the transmission line. The cutting blade installed on the carrier plate 8 rotates under the drive of the motor, thereby cutting and removing plastic bags and other debris attached to the transmission line.

[0026] See Figures 1-7A support plate 3 is mounted on the outer surface of the bracket 2. A strip groove 4 is formed on the upper surface of the support plate 3. Two movable seats 14 are provided on the upper side of the strip groove 4. A connecting seat 16 is installed at the bottom of the electric gripper 13, so that the connecting seat 16 is connected to the movable seat 14 by screws, thus completing the assembly of the movable seat 14 and the electric gripper 13. A protrusion 21 is fixedly connected to the lower surface of the movable seat 14. The protrusion 21 penetrates the strip groove 4. The width of the protrusion 21, which is integrally formed with the movable seat 14, is the same as the width of the strip groove 4. A through hole 25 is formed on one side of the protrusion 21. A screw 15 is inserted inside the 25, and the end of the screw 15 is connected to the support plate 3. The screw 15 is arranged along the length of the strip groove 4. Adjusting nuts 19 are provided on both sides of the protrusion 21. The adjusting nuts 19 are threadedly connected to the screw 15. Two symmetrically arranged end ears 17 are installed on the lower surface of the support plate 3. The end of the screw 15 passes through the end ears 17. Both ends of the screw 15 are threadedly connected to limit nuts 18. The two end ears 17 on one support plate 3 are positioned between the two limit nuts 18 on the corresponding screw 15. The limit nuts 18 and the end ears 17. Working together, the pallet 3 and screw 15 are assembled. When passing over the anti-vibration hammer and intermediate bar, the two electric grippers 13 on the side closer to the anti-vibration hammer and intermediate bar do not grip the power transmission line, while the two electric grippers 13 on the side farther from the anti-vibration hammer and intermediate bar grip the power transmission line. Then, the first servo motor 5 is controlled to rotate, causing the support roller 11 to move to the side of the power transmission line. After the support roller 11 passes over the anti-vibration hammer and intermediate bar, the two electric grippers 13 on the front side of the moving direction grip the power transmission line, while the two electric grippers 13 on the rear side of the moving direction do not grip the power transmission line. Now, it successfully passes over the vibration damper and the intermediate bar. According to the length of the vibration damper, adjust the position of the two movable seats 14 on one support plate 3. At this time, the distance between the two electric grippers 13 on one support plate 3 changes, and the relative position of the protrusion 21 and the screw 15 changes. When the distance between the two electric grippers 13 on one support plate 3 meets the requirement of passing over the vibration damper, the relative position of the screw 15 and the protrusion 21 can be limited by the adjusting nut 19. This realizes the adjustment of the distance between the cooperating electric grippers 13, which is convenient for passing over vibration dampers of different lengths.

[0027] See Figure 2 , Figure 5 and Figure 6 The lower surface of the protrusion 21 has a notch 20, which communicates with the through hole 25. When the screw 15 and the adjusting nut 19 cannot be turned normally due to corrosion, the space of the notch 20 is used to cut off the part of the screw 15 inside the notch 20, so as to facilitate the replacement of the screw 15.
