Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage power line inspection technology, specifically to an X-ray inspection robot for four-split conductors of power transmission lines. Background Technology
[0002] Existing methods for inspecting high-voltage power lines typically involve using drones for DR imaging. However, these drone-based inspection devices are mostly designed for single-wire or multi-wire clamps. When used to inspect split conductors, the excessive spacing between each split conductor limits the ability to inspect only a portion of the conductors at a time. To inspect all conductors, the drone must be mounted on different conductors multiple times, resulting in low inspection efficiency. Therefore, the applicant of this patent provides a drone-based X-ray inspection robot and method for four-split conductors, as described in Reference 1.
[0003] Reference 1: Chinese patent document with patent publication number CN118549471A.
[0004] Reference 1 discloses a UAV-based X-ray inspection robot for four-splitter conductors and an inspection method therefor. The robot includes a frame that is mounted on and travels along the split conductors. The frame includes a main body and a centrally located support frame. The frame has a rectangular hanger and positioning parts at the four corners of the lower end of the rectangular hanger. Two opposing positioning parts, parallel to the frame, are rotatably connected to rotating rods. One end of each rotating rod has a traveling roller, and a longer traveling roller is also provided at one end of the rotating rod to adapt to inspection scenarios where the spacing between the split conductors at the same horizontal level varies.
[0005] However, as described in Reference 1, the traveling roller has a small contact area with the split conductor, which means that environmental factors such as high-altitude winds and rain or snow making the surface of the split conductor too smooth can cause the split conductor to separate from the traveling roller, resulting in the equipment tipping over and falling. Utility Model Content
[0006] The purpose of this invention is to solve the problem in the prior art where the traveling roller is easily affected by the environment and separates from the corresponding split conductor, causing the equipment to tip over and fall. This invention provides an X-ray inspection robot for four-split conductors of power transmission lines.
[0007] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a robot for X-ray inspection of four-split conductors of transmission lines, comprising a rectangular frame with a suspension rope at the top, an imaging component and an X-ray machine for inspection at both ends of the rectangular frame, and a traveling roller and a wheel on the rectangular frame. The rectangular frame is provided with support columns on both sides along its traveling direction, and each of the two support columns is provided with a locking clamp and a moving plate. The locking clamp includes a docking part that bends from the outside to the inside to bypass the upper split conductor and a recurved part that bends from the inside to the outside.
[0008] The upper ends of the two movable plates are respectively provided with the two ends of the same power rope, and the middle part of the power rope is fixed to the hoisting rope;
[0009] The movable plate can slide vertically relative to the supporting column. A top pressure rod is fixedly provided at the lower part of the movable plate. The top pressure rod corresponds to the inner side of the anti-curved part so that the top pressure rod can press the anti-curved part and drive the anti-curved part to unfold and extend from the inside to the bottom of the split wire.
[0010] As a further optimization of the X-ray inspection robot for four-split conductors of transmission lines of this utility model: a rolling assembly is provided on the inner side of the docking part and the outer side of the lower side of the recurved part. The rolling assembly is composed of a ball seat with internal balls and a locking clamp.
[0011] As a further optimization of the X-ray inspection robot for four-split conductors of transmission lines of this utility model: a sliding groove is provided on the moving plate, and the sliding groove slides in cooperation with the limiting block provided on the bearing column, and both the sliding groove and the limiting block are rectangular.
[0012] As a further optimization of the X-ray inspection robot for four-split conductors of transmission lines of this utility model: a top pressure spring is provided between the lower side of the sliding groove and the limiting block, and the top pressure rod is made of solid rubber.
[0013] As a further optimization of the X-ray inspection robot for four-split conductors of transmission lines of this utility model: the docking part is provided on the side facing the imaging component, corresponding to the moving plate, so that the moving plate covers the docking part when the top pressure rod presses down on the curved part.
[0014] As a further optimization of the X-ray inspection robot for four-split conductors of power transmission lines of this utility model: multiple reinforcing ribs are provided between the connection between the bearing column and the rectangular bracket.
[0015] As a further optimization of the X-ray inspection robot for four-split conductors of power transmission lines of this utility model: a gap is provided at the center of the locking clamp, and the opening direction of the gap is perpendicular to the length direction of the split conductor.
[0016] As a further optimization of the X-ray inspection robot for four-split conductors of transmission lines of this utility model: the locking clamp is S-shaped, the locking clamp is made of elastic metal, and the surface of the locking clamp is provided with an anti-rust coating.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention connects the locking clamp's mating part to the upper split wire, thereby improving the connection stability between the traveling roller and the upper split wire. Furthermore, by using a top pressure bar and a top pressure spring to drive the moving plate downward, the top pressure bar presses against the reverse curve of the locking clamp, causing the lower side of the reverse curve to connect to the lower split wire. This further stabilizes the connection stability between the upper split wire and the traveling roller, reducing the probability of the upper split wire separating from the traveling roller and causing the equipment to tip over and fall.

[0022] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.
[0023] like Figure 1 and Figure 2 As shown, an X-ray inspection robot for four-split conductors of a power transmission line includes a rectangular frame 902 and imaging components 901 and X-ray machines 905 located on both sides of the rectangular frame 902. The rectangular frame 902 is equipped with a hoisting rope 903 for a drone to hoist the rectangular frame 902 and drive it to move. The rectangular frame 902 is equipped with rollers and traveling rollers 904. The rectangular frame 902 presses against the uppermost split conductor 8 through the rollers and traveling rollers 904, and can move on the split conductor 8 to allow the imaging components 901 and X-ray machines 905 to inspect different positions of the split conductor 8. It can also inspect multiple split conductors 8 with different split shapes in a single operation.
[0024] The rectangular bracket 902 has two supporting columns 5 on both sides facing the length of the split conductor 8 and near the traveling roller 904. Each supporting column 5 has a locking clip 1, which can enter between two adjacent split conductors 8 on the side near the traveling roller 904. A pressure bar 2 is correspondingly provided inside the lower side of the locking clip 1. Figure 1 As shown, the weight of the top pressure bar 2 can press the locking clamp 1 to deform it, so that the upper inner side of the locking clamp 1 presses against the upper split wire 8, and the lower outer side presses against the lower split wire 8. Then, the rectangular bracket 902 can be locked relative to the two adjacent vertically distributed split wires 8 on the side facing the traveling roller 904, thereby reducing the probability that the rectangular bracket 902 will be affected by environmental factors, causing the traveling roller 904 to detach from the split wires 8 and causing the rectangular bracket 902 to tip over and fall.
[0025] Both top pressure rods 2 are fixedly connected to movable plates 3, and the two movable plates 3 are fixedly connected to both ends of a power rope 7. The power rope 7 is wrapped together with the lifting rope 903. When using a drone to remove the rectangular bracket 902, if... Figure 2 As shown, the power rope 7 will rise synchronously, and then the two moving plates 3 will move the two top pressure bars 2 to reset the locking clamp 1 and release its connection with the split wire 8, thus completing the lifting of the rectangular hanger 902.
[0026] The locking clamp 1 is S-shaped. The upper side of the locking clamp 1 is fixedly connected to the bearing column 5. The upper inner side of the locking clamp 1 forms a docking part 103 corresponding to the upper split wire 8. The lower outer side of the locking clamp 1 is a curved part 102. Both the curved part 102 and the docking part 103 are made of elastic metal so that the curved part 102 can deform and unfold when pressed by the top pressure bar 2, that is, change its unfolded length to connect with the lower split wire 8, or automatically reset when not pressed by the top pressure bar 2, so as to separate from the lower split wire 8 for the rectangular hanger 902 to lift.
[0027] The bottom exterior of the docking part 103 and the curved part 102 of the locking clamp 1 are both provided with rolling components 101. The rolling components 101 are composed of ball seats with balls inside, and the ball seats are fixed on the locking clamp 1, so that the balls press against the surface of the split wire 8, thereby reducing the friction between the locking clamp 1 and the split wire 8, so as to reduce the mutual wear between the locking clamp 1 and the split wire 8 when the rectangular bracket 902 moves.
[0028] The center of the locking clamp 1 is provided with a gap 104 that communicates with the outside. The gap 104 is arranged along the axial direction of the traveling roller 904. After the locking clamp 1 passes the split guide wire 8, the locking clamp 1 can clean the dust or snow on the split guide wire 8 and discharge the dust and snow from the gap 104, thereby reducing the impact of snow or dust on the traveling roller 904.
[0029] The locking clip 1 has an anti-rust coating on its surface to reduce the probability of the locking clip 1 rusting due to external environmental influences, thereby maintaining the elastic properties and service life of the locking clip 1.
[0030] The movable plate 3 is set with a corresponding gap 104 so that the movable plate 3 can cover the docking part 103 of the locking clamp 1 to restrict the upper split wire 8 into the docking part 103. Then, it can cooperate with the bearing column 5 to restrict the rectangular bracket 902 onto the corresponding split wire 8.
[0031] The movable plate 3 is provided with a sliding groove 4, which is rectangular in shape, and a limiting block 6 slides in the sliding groove 4. The limiting block 6 is rectangular in shape and is fixedly connected to the bearing column 5, so that the movable plate 3 can slide vertically on the bearing column 5.
[0032] A top pressure spring 10 is provided between the sliding groove 4 and the limiting block 6. The top pressure spring 10 can push the moving plate 3 downward under the support of the limiting block 6, and then cooperate with the weight of the top pressure rod 2 made of solid rubber to stabilize the top pressure locking clamp 1, so that the locking clamp 1 deforms and drives the recurved part 102 to connect with the power rope 7 on the lower side.
[0033] Multiple reinforcing ribs are provided between the support column 5 and the rectangular bracket 902. The multiple reinforcing ribs are arranged around the support column 5 to maintain the connection stability between the support column 5 and the rectangular bracket 902, and at the same time maintain the stability of the relative position of the locking clamp 1 and the moving plate 3.
[0034] In practical use, the rectangular bracket 902 is first placed on the split wire 8, that is, the locking clamp 1, under the state of pressing the upper split wire 8, enters between the upper split wire 8 and the lower split wire 8, thereby assisting the drone to place the rectangular bracket 902 stably on the two upper split wires 8 to a certain extent.
[0035] As the rectangular hanger 902 is gradually placed onto the split conductor 8, the lifting rope 903 and the power rope 7 pulled upward by the drone will be gradually loosened. Then, the docking part 103 of the locking clamp 1 will be connected to the upper split conductor 8. At the same time, the moving plate 3 will be driven by the weight of the top pressure spring 10 and the top pressure bar 2 to slide vertically under the restriction of the limiting block 6 and the sliding groove 4. After that, the two top pressure bars 2 will press the anti-curved part 102 to connect the bottom outer side of the anti-curved part 102 with the lower split conductor 8, so as to stably position the rectangular hanger 902 onto the split conductor 8.
[0036] Then, the rectangular bracket 902 can be moved on the split guide wire 8 to cooperate with the imaging component 901 and the X-ray machine 905 to perform X-ray inspection on multiple split guide wires 8. During the movement, the locking clamp 1 will clean the split guide wire 8 connected to the traveling roller 904 to assist the traveling roller 904 in moving stably on the split guide wire 8.
[0037] When the inspection is completed and the rectangular bracket 902 needs to be lifted off the split conductor 8, the power rope 7 and the lifting rope 903 will be pulled upward by the drone. Then the two moving plates 3 will be driven to move vertically upward stably while overcoming the weight of the top pressure spring 10 and the top pressure rod 2. After that, the curved part 102 will use its own material to reset and separate from the lower split conductor 8. Then it can be pulled off the split conductor 8 by the drone for subsequent reuse.
[0038] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
