Description

Technical Field

[0001] This utility model relates to the field of high-voltage line maintenance technology, and in particular to a high-altitude X-ray inspection device for a four-split high-voltage transmission line. Background Technology

[0002] Overhead transmission lines extensively use crimp-type electrical fittings such as tension clamps and straight-line splicing conduits for connecting conductors and ground wires. These fittings must withstand the full tension of the conductors and ground wires and also act as conductors, and are not removed after installation. During construction, if the conductors and ground wires are not properly inserted into the crimping conduits or if the steel core crimping does not meet requirements, it will pose a significant hidden danger to the safe operation of the line. Nationwide, numerous accidents involving line breaks and drops have occurred due to substandard crimping quality of tension clamps or splicing conduits. Therefore, non-destructive testing of tension clamps and splicing conduits to prevent such accidents is crucial. X-ray non-destructive testing, as a conventional non-destructive testing method, has been widely adopted in the field of power testing technology. X-ray digital imaging technology utilizes the strong penetrating power of X-rays; the rays penetrating the tested object carry information reflecting the internal structure of the object. By observing changes in the intensity of the rays, the nature, size, and distribution of various macroscopic or microscopic defects within the tested workpiece can be detected.

[0003] The patent publication number CN118583894A discloses an X-ray flaw detection system for power transmission lines. This system can detect various conditions of cable conductors with different spacings and multiple types of split conductors, and can flexibly change the cable for flaw detection. It has the advantages of stable mounting of flaw detection equipment and stable imaging effect. However, this application cannot automatically move the flaw detection equipment up, down, left and right. When detecting flaws in cables up, down, left and right, it needs to be pulled by a drone to move to the detection position, which is inconvenient to operate, inefficient, and poses safety hazards.

[0031] Example 1

[0032] See attached document Figure 1-9This application provides a high-altitude X-ray inspection device for a four-split high-voltage transmission line, including a walking assembly 1 and a detection assembly 2. The walking assembly 1 is used to walk on the power line and includes a frame 3 and drive wheels 4. The frame 3 is provided with flexible hanging points 5, and the drive wheels 4 are connected to the frame 3 and driven by a drive motor 6. All motors are connected to a power supply. The detection assembly 2 includes an X-ray mounting box 7 and an imaging plate 8. The X-ray mounting box 7 contains an X-ray machine, and the X-ray machine and the imaging plate 8 are arranged in parallel. The frame 3 is provided with a DR imaging detection control. Device 33 uses an X-ray machine and imaging plate 8 to perform flaw detection on the wire. A drone is used to lift the detection device above the four-split cable by attaching it to flexible suspension point 5 via a flexible rope. The flexible rope can be arranged in an I-shape to ensure the device remains horizontal during drone hoisting. The X-ray mounting box 7 also contains a camera. When the detection device is suspended above the cable, the operator observes the position of the device wheels relative to the cable through the camera on the X-ray machine mounting box. Ensuring the wheels are aligned with the cable, the operator operates the drone to release the device, and simultaneously the drone flies away from above the device. The unit is suspended and in standby mode. A horizontal movement assembly 9 is mounted on the frame 3. This assembly drives the detection assembly 2 to move laterally, facilitating the detection of cables on both sides. The horizontal movement assembly 9 can be a module, a cylinder, or a hydraulic cylinder, etc. A lifting assembly 10 is mounted on the output end of the horizontal movement assembly 9. This lifting assembly 10 drives the detection assembly 2 to move longitudinally, facilitating the detection of cables arranged vertically. The horizontal movement assembly 9 can be a module, a cylinder, or a hydraulic cylinder, etc. The detection assembly 2 is connected to the output end of the lifting assembly 10. The horizontal movement assembly 9 drives the detection... Component 2 moves laterally for detection. The lifting component 10 drives the detection component 2 to move longitudinally for detection. During operation, the drone is used to lift the detection device above the four-split cable. The operator observes the position of the equipment wheels relative to the cable through the camera mounted on the X-ray machine mounting box. Under the premise of ensuring that the wheels are aligned with the cable, the drone is operated to release the equipment. At the same time, the drone flies away from the equipment and hovers above it for standby. The operator drives the drive wheel 4 to walk on the cable to the working area through the remote control. When the center of the imaging plate 8 is observed to be below the crimping tube through the camera, the equipment stops moving.The transverse component 9 is controlled to move laterally to inspect the crimping pipes on both sides. When inspecting the crimping pipes on the lower two sides, the X-ray machine is first centered, and the lifting component 10 is operated to move up and down. When the imaging plate 8 is observed to be above the next layer of crimping pipe, the above steps are repeated to complete the inspection of the crimping pipe. After the inspection is completed, the X-ray machine is reset, the operator controls the equipment to leave the working area, and the drone returns to retrieve the equipment. This application uses the walking component 1 to move horizontally on the cable to the inspection position, observes the status through the camera, and uses the transverse component 9 and the lifting component 10 to perform flaw detection on the cables in all directions. It is convenient, fast, simple and efficient, and does not require additional equipment to move the inspection device to the inspection point. The X-ray machine and the imaging plate 8 are set in parallel, resulting in good flaw detection effect.
