TECHNICAL FIELD
[0001] The application belongs to the technical field of power transmission line maintenance, and particularly relates to an X-ray plate auxiliary positioning device for high-voltage transmission lines. BACKGROUND
[0002] The line clamp of a transmission line is an important component for connecting conductors, which is responsible for bearing the weight of the conductors and the impact of natural environment such as wind and rain. Since the line clamp is in the high-altitude environment for a long time, it is greatly affected by external forces and the environment, and is prone to problems such as cracks, corrosion, and fatigue. If these problems are not discovered and addressed in a timely manner, the line clamp may fail, which may lead to safety accidents such as cable falling off and breaking. Therefore, it is necessary to perform flaw detection on the line clamp of a transmission line. Through flaw detection technology, defects and problems of the line clamp can be discovered in a timely manner, and maintenance and replacement can be performed in a timely manner to ensure the safe operation of the transmission line. At the same time, flaw detection technology can also help to improve the service life of the line clamp, reduce maintenance costs, and improve the reliability and stability of the transmission line.
[0003] At present, the commonly used flaw detection technology is mainly X-ray flaw detection, which has the characteristics of rapid and intuitive, but personnel need to carry heavy X-ray plates to high-altitude work of overhead transmission lines, which is extremely inconvenient. In recent years, many places have also explored the use of unmanned aerial vehicles to carry X-ray plates for line clamp flaw detection operations of overhead transmission lines. However, for four-split or more split conductors, the traditional unmanned aerial vehicle hanging plate method cannot meet the requirements due to the obstruction of the line clamp structure and the equalizing ring. Therefore, it is necessary to design a flaw detection plate auxiliary mounting device that can be carried and placed by an unmanned aerial vehicle and adapt to the connection structure of the line clamp, which can perform flaw detection operations under the condition of live line. SUMMARY
[0004] The purpose of the present application is to overcome the defects and deficiencies of the prior art, and to provide an X-ray plate auxiliary positioning device for high-voltage transmission lines, which can accurately drive the X-ray plate to move up and down and left and right within a certain range during X-ray flaw detection operations on high-voltage transmission lines, thereby achieving accurate positioning of the line clamp flaw detection position, reducing the operation difficulty of placing the X-ray plate in high-altitude operations, and reducing the operation risk.
[0005] The technical problem of the present application is solved by the following technical solution: An auxiliary positioning device for X-ray plates in high-voltage transmission lines includes a vertical slide rail bracket, a support frame, horizontal drive rollers, a vertical drive motor, a buffer module, a battery, and a remote control module. The vertical rod of the vertical slide rail bracket has a front and rear perforated design in its middle section, allowing the X-ray plate to be fixed on the vertical slide rail bracket for photosensitive imaging. The support frame is connected to both sides of the vertical slide rail bracket via the buffer module. The horizontal drive rollers are installed inside the support frame and are driven by the motor to move back and forth along the conductor direction. The vertical drive motor is installed on the vertical slide rail bracket, driving the X-ray plate to move up and down. The battery and remote control module are installed at the front end of the vertical slide rail bracket, controlling the operation of the vertical drive motor.
[0006] Moreover, the support frame is a hollow square-folded tube.
[0007] Furthermore, the vertical slide rail bracket is made of PVC material.
[0008] Furthermore, the buffer module consists of a buffer spring and a spring fixing rod, and there are four sets of them arranged between the support frame and the vertical slide rail bracket.
[0009] The advantages and beneficial effects of this invention are as follows: This invention features an X-ray plate mounting and fixing function on the conductor, ensuring that the photosensitive plate does not easily shake during high-altitude operations and remains stable. At the same time, under the action of the vertical drive motor and the horizontal drive motor, the cable clamp is precisely aligned and positioned, avoiding personnel from going online. It can efficiently and safely complete flaw detection operations when the line is energized. Attached Figure Description

[0012] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.
[0013] This invention relates to an auxiliary positioning device for X-ray plates of high-voltage transmission lines. Its innovation lies in the following: it includes 1-vertical slide rail bracket, 2-device support frame, 3-horizontal drive roller, 4-vertical drive motor, 5-equipment buffer module, 6-battery and remote control module, and 7-wire locking mechanism.
[0014] like Figure 2 As shown, the vertical slide rail bracket-1 is made of high-strength PVC material, which must meet high-voltage insulation requirements. The middle section of the vertical rod has a front and rear perforation design to meet the requirements of the gear transmission structure. The bracket can fix the X-ray plate-8 for photosensitive imaging. The main body of the vertical slide rail bracket serves as the main structure of the device, supporting all other modules.
[0015] like Figure 3 As shown, the device support frame-2 consists of two sets, each being a single hollow square-folded tube. The equipment buffer module-5 connects the device support frame-2 to the vertical slide rail bracket-1, fulfilling the overall device's support requirements on the overhead cable, thus forming... Figure 1 The overall structure of the device; like Figure 4 As shown, there are two sets of horizontal drive rollers-3. One set is installed on the left side of the vertical slide rail bracket-1, and the other set is installed on the right side of the vertical slide rail bracket-1. They are driven by a motor and can drive the trolley to move forward and backward along the direction of the guide wire. like Figure 5 As shown, the vertical drive motor assembly-4 consists of a drive motor and transmission gears, and is bolted to the vertical slide rail bracket-1. It can control the photosensitive plate to move up and down under the action of the drive motor. like Figure 6 As shown, the equipment buffer module-5 consists of buffer springs and spring fixing rods, with a total of four sets. Two sets are installed on each of the left and right sides of the device, which are used to connect the device support frame-2 and the vertical slide rail bracket-1.
[0016] like Figure 1 As shown, the 6-battery and remote control module consists of a horizontal drive motor, a battery module, and a remote control module. It adopts an integrated design and is reasonably arranged inside the protective box, and is fixed to the bottom of the hollow fixing tube by bolts. like Figure 1As shown, the 7-wire locking device can be flipped 90°. The device is placed in front of the cable, and the locking device is in a relatively parallel position with the power transmission cable. After the device is connected to the line, the locking device can be remotely controlled to be flipped 90°, so that it is in a relatively cross position with the power transmission cable, which is used to lock the device and improve stability.
[0017] The working principle of this invention is as follows: Using a drone, the entire device is lifted to the conductor where flaw detection is to be performed, approximately 3-4 meters from the wire clamp. It is then slowly lowered so that the device sits atop the conductor, with its horizontal drive roller resting on the conductor. The drone's slow descent transfers the entire weight of the device to the conductor. At this point, the remote-controlled wire clamp engages, securing the entire device to the conductor. Figure 7 As shown.
[0018] Use the remote control to move the device along the direction of the wire to the clamp, and adjust its position relative to the clamp.
[0019] When the X-ray plate needs to be moved vertically, a signal is sent to the 4-vertical drive motor assembly via a ground remote control, and the drive motor can then move the 1-vertical slide rail bracket up and down as a whole.
[0020] When it is necessary to move the X-ray plate horizontally, the device can be moved horizontally as a whole by transmitting a signal to the 6-battery and remote control module via a ground remote controller.
[0021] This structure requires simple materials, is easy to process, has low cost, is easy to assemble, has a high yield, and its total cost is far lower than that of other designs. It is also easy to use.
[0022] During X-ray flaw detection, a drone carries the device and places it at the overhead power line conductor, away from the wire clamp. After placement, the device's mounting bracket locks the conductor in place, ensuring the device's stability at high altitude. Meanwhile, ground personnel remotely control the device's movement along the cable direction, while the X-ray plate mounted on the device moves up and down within a certain range. This allows the X-ray plate to be accurately aligned with the wire clamp requiring X-ray inspection. The drone, carrying an X-ray machine, then irradiates the clamp, creating an internal structural diagram on the X-ray plate to identify potential internal failures. Using this device eliminates the need for personnel to climb the power line, reduces the difficulty of accurately placing the X-ray plate during drone operations, improves work efficiency, and reduces operational risks.
[0023] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
