Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) inspection technology for power systems, specifically an auxiliary positioning device for X-ray flaw detection photosensitive plates of transmission lines. Background Technology
[0002] Line clamps are crucial components connecting cables and cable towers, bearing the weight of the cables and the impact of wind, rain, and other environmental factors. Because line clamps are constantly exposed to high-altitude environments, they are subject to significant external forces and environmental influences, making them prone to cracking, corrosion, and fatigue. If these problems are not detected and addressed promptly, they can lead to clamp failure, resulting in cable detachment, breakage, and other safety accidents. Therefore, flaw detection of line clamps is essential. Flaw detection technology allows for the timely detection of defects and problems in the clamps, enabling prompt repair and replacement, ensuring the safe operation of transmission lines. Furthermore, flaw detection technology can help extend the service life of the clamps, reduce maintenance costs, and improve the reliability and stability of transmission lines.
[0003] A search of Chinese Patent Network CN219998896U reveals an auxiliary positioning device for an X-ray flaw detection photosensitive plate of a high-voltage transmission line. This device achieves power and guidance functions by using an elongated hole on a connecting sleeve. The power function is achieved by the vertical drive motor's output end radially penetrating the elongated hole and engaging with the lifting racks at both ends of the lifting carriage. The guidance function is achieved by the horizontal guide rod's ends penetrating the elongated hole and being fixed to the positive surfaces at both ends of the lifting carriage. One function of this horizontal guide rod is to provide sliding guidance for the X-ray flaw detection photosensitive plate during translational adjustment. Another function is that the horizontal guide rod and the elongated hole's upper and lower limit positions together constitute the limit position constraints for the lifting carriage's upward and downward sliding, preventing the lifting carriage from detaching from the UAV mount.
[0004] However, there are usually multiple sets of high-voltage lines on the same side of the high-voltage tower, and the structure designed above can only realize the tension clamp flaw detection on a single high-voltage line. It is necessary to manually operate the drone multiple times to change the position before the high-voltage flaw detection operation can be completed, resulting in low efficiency of tension clamp detection on high-voltage lines. Therefore, an auxiliary positioning device for X-ray flaw detection photosensitive plate of transmission lines is proposed. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide an auxiliary positioning device for X-ray flaw detection photosensitive plates of power transmission lines, so as to solve the technical problems mentioned in the background.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary positioning device for an X-ray flaw detection photosensitive plate for transmission lines, comprising two sets of support frames, each set of support frames having two sets of electric push rods installed in an inverted position, an F-frame fixed to the top of the two sets of electric push rods, a frame seat fixed between the top of the two sets of support frames, and an X-ray flaw detection photosensitive plate assembled on the top of the frame seat;
[0007] Each set of support frames is equipped with a second lead screw that rotates within the frame. The outer wall of the second lead screw is threaded and fixed to a sleeve block at the bottom of the frame base. A drive motor that drives the second lead screw to rotate is installed at the front end of the support frame. A balance bar is slidably provided at the bottom of the support frame. A clearance groove is reserved at the top of the balance bar. A timing belt is installed in the support frame below the second lead screw. The bottom of the sleeve block is fixed to the upper surface of the timing belt. A driven block connected to the clearance groove is fixed to the lower surface of the timing belt.
[0008] As a preferred technical solution, the top of the two sets of F-frames is welded with a mounting beam for the drone to hook onto, and the outer wall of each set of F-frames is fixed with a vertically downward V-shaped frame.
[0009] As a preferred technical solution, a dual-head motor is installed in the center of the frame, and the two ends of the dual-head motor are connected to a first lead screw that rotates on the inner wall of the frame. The outer wall of each set of first lead screws is threaded with a driven sleeve that is fixed to the bottom of the X-ray flaw detection photosensitive plate.
[0010] As a preferred technical solution, the top of the X-ray flaw detection photosensitive plate is slidably provided with a U-frame extending between two sets of electric push rods. The top of the U-frame is fixedly slidably attached to a ball-head rod on the outer wall of the electric push rod. The curved outer wall of the electric push rod is reserved with a travel groove for the front and rear ends of the ball-head rod to slide.
[0011] As a preferred technical solution, two sets of transmission shafts are provided near both ends of the synchronous belt, and the two sets of transmission shafts are rotatably connected to the inner wall of the support frame.
[0012] As a preferred technical solution, a support beam is welded between the two sets of support frames, and the two sets of support beams are located near the front and rear ends of the support frames.
[0013] As a preferred technical solution, a battery for supplying electrical energy to electric push rods, drive motors and dual-head motors is installed between the two sets of support beams and between the two sets of support frames.
[0014] In summary, the present invention has the following main advantages:
[0015] This invention utilizes the cooperation of a support frame and a U-frame to allow the X-ray flaw detection photosensitive plate to move laterally and backward, moving closer to the adjacent high-voltage power line. This enables flaw detection of multiple sets of tension clamps on high-voltage lines, improving the efficiency of flaw detection of tension clamps on high-voltage lines. At the same time, the balance bar moves in the opposite direction to the X-ray flaw detection photosensitive plate, ensuring the stability of the device and placing it vertically on one side of the high-voltage power line.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The embodiments of this utility model will be described below based on its overall structure.
[0023] An auxiliary positioning device for X-ray flaw detection photosensitive plates of power transmission lines, such as Figures 1 to 4 As shown, it includes two sets of support frames 100. Each set of support frames 100 is inverted and has two sets of electric push rods 120 installed. An F-frame 130 is fixed to the top of the two sets of electric push rods 120. A frame base 160 is fixed between the two sets of electric push rods 120 at the top of the two sets of support frames 100. An X-ray flaw detection photosensitive plate 110 is assembled on the top of the frame base 160.
[0024] Each set of support frames 100 is rotatably equipped with a second lead screw 171. The outer wall of the second lead screw 171 is threaded and fixed to the sleeve block 161 at the bottom of the frame seat 160. The front end of the support frame 100 is equipped with a drive motor 170 that drives the second lead screw 171 to rotate. The bottom of the support frame 100 is slidably equipped with a balance bar 180. The top of the balance bar 180 is reserved with a clearance groove 181. A timing belt 190 is assembled in the support frame 100 below the second lead screw 171. The bottom of the sleeve block 161 is fixed to the upper surface of the timing belt 190. The lower surface of the timing belt 190 is fixed with a driven block 191 connected to the clearance groove 181.
[0025] The top of the two sets of F-frames 130 is welded with a mounting beam 140 for the drone to be hooked, and the outer wall of each set of F-frames 130 is fixed with a vertically downward V-shaped frame 131.
[0026] A drone is used to attach to the mounting beam 140 and raise the device, so that the V-shaped frame 131 is attached to the outer wall of the high-voltage power line (the V-shaped frame 131 is made of insulated metal). The device is suspended on one side of the power line. Another drone carrying X-ray imaging equipment is controlled to take pictures of the high-voltage power line tension clamp with the X-ray flaw detection photosensitive plate 110 as the background for X-ray flaw detection. The electric push rod 120 can raise and lower the X-ray flaw detection photosensitive plate 110, so that the tension clamp on the high-voltage power line is in the center of the surface of the X-ray flaw detection photosensitive plate 110. At the same time, it can meet the laying of the upper and lower high-voltage lines. The personnel can continue to control the drive motor 170 to work. At this time, the second lead screw 171 will rotate, and through the driven sleeve 164, it will drive the frame seat 160 to move back and forth on the top of the two sets of support frames 100, so that the X-ray flaw detection photosensitive plate 110 moves back and forth and gets closer to the high-voltage line, and flaw detection is performed with the X-ray flaw detection photosensitive plate 110 as the background.
[0027] When the X-ray flaw detection photosensitive plate 110 moves forward and backward, the driven sleeve 164 drives the synchronous belt 190 to move synchronously, and the driven block 191 drives the balance bar to move in the opposite direction, so as to maintain the force balance of the device and prevent it from tilting on the high voltage line, thereby ensuring that the X-ray flaw detection photosensitive plate 110 is in a horizontal state on one side of the high voltage line.
[0028] Please refer to this carefully. Figure 4 A dual-head motor 162 is installed in the center of the frame 160. The two ends of the dual-head motor 162 are connected to a first lead screw 163 that rotates on the inner wall of the frame 160. The outer wall of each set of first lead screws 163 is threaded with a driven sleeve 164 that is fixed to the bottom of the X-ray flaw detection photosensitive plate 110.
[0029] When the dual-head motor 162 is working, its output end will drive the first lead screw 163 to rotate, which will drive the X-ray flaw detection photosensitive plate 110 to move laterally through the driven sleeve 164. This can correct the position of the X-ray flaw detection photosensitive plate 110 and better detect flaws on the wires against the background.
[0030] Please refer to this carefully. Figure 1 and Figure 2 The top of the X-ray flaw detection photosensitive plate 110 is provided with a U-frame 150 extending between two sets of electric push rods 120. The top of the U-frame 150 is fixed to a ball head rod 151 that slides on the outer wall of the electric push rod 120. The curved outer wall of the electric push rod 120 is reserved with a travel groove 121 for the front and rear ends of the ball head rod 151 to slide.
[0031] It can drive the ball joint 151 to slide up and down in the stroke groove 121, so that the raised and lowered X-ray flaw detection photosensitive plate 110 is in a stable state, and drive the X-ray flaw detection photosensitive plate 110 to move smoothly laterally in the U frame 150 to change its position.
[0032] Please refer to this carefully. Figure 2 and Figure 3 Two sets of drive shafts are provided near both ends of the synchronous belt 190, and the two sets of drive shafts are rotatably connected to the inner wall of the support frame 100.
[0033] The drive shaft is used to limit the timing belt 190, keeping it taut so that it can perform transmission.
[0034] Please refer to this carefully. Figure 1 Support beams are welded between the two sets of support frames 100, and the two sets of support beams are located near the front and rear ends of the support frames 100.
[0035] A battery is installed between the two sets of support beams and between the two sets of support frames 100 to supply power to the electric push rod 120, drive motor 170 and dual-head motor 162.
[0036] The support beam enhances the strength between the two sets of support frames 100, so that it can stably support the X-ray flaw detection photosensitive plate 110.
[0037] Simultaneously, the battery provides power to the electric push rod 120, drive motor 170, and dual-head motor 162, assisting the X-ray flaw detection photosensitive plate 110 in completing the flaw detection of the high-voltage wire clamp.
[0038] In use, a drone is attached to the mounting beam 140 and used to raise the device, so that the V-frame 131 is attached to the outer wall of the high-voltage power line (the V-frame 131 is made of insulated metal). The device is suspended on one side of the power line. Another drone carrying X-ray imaging equipment is controlled to take pictures of the high-voltage power line tension clamp with the X-ray flaw detection photosensitive plate 110 as the background for X-ray flaw detection. The electric push rod 120 can raise and lower the X-ray flaw detection photosensitive plate 110, so that the tension clamp on the high-voltage power line is in the center of the surface of the X-ray flaw detection photosensitive plate 110. At the same time, it can meet the requirements of laying the upper and lower high-voltage lines. The personnel can continue to control the drive motor 170 to work. At this time, the second lead screw 171 will rotate, and through the driven sleeve 164, it will drive the frame seat 160 to move back and forth on the top of the two sets of support frames 100, so that the X-ray flaw detection photosensitive plate 110 moves back and forth and gets closer to the high-voltage line, and flaw detection is performed with the X-ray flaw detection photosensitive plate 110 as the background.
[0039] When the X-ray flaw detection photosensitive plate 110 moves forward and backward, the driven sleeve 164 drives the synchronous belt 190 to move synchronously, and the driven block 191 drives the balance bar to move in the opposite direction, so as to maintain the force balance of the device and prevent it from tilting on the high voltage line, thereby ensuring that the X-ray flaw detection photosensitive plate 110 is in a horizontal state on one side of the high voltage line.
