Description

Technical Field

[0001] This invention relates to the field of laser obstacle removal technology, specifically to a laser target calibration device for a laser obstacle removal system. Background Technology

[0002] Laser obstacle removal systems, as a highly efficient and non-contact removal technology, have been widely used in industrial fields such as power grids, rail transportation, and petrochemicals in recent years. This system precisely focuses a high-energy laser beam onto the surface of obstacles (such as hanging objects on transmission lines, ice on insulators, and foreign objects on rail transit contact networks), causing the target object to melt or vaporize in a short time, thereby achieving rapid removal. It has significant advantages such as high safety, strong adaptability, and minimal damage to the carrier. However, the accuracy of the alignment between the laser target point and the actual position of the obstacle directly determines the obstacle removal effect. If the target point is off-center, not only will the obstacle not be effectively removed, but it may also damage surrounding normal facilities and even cause secondary safety hazards. Therefore, the laser target point calibration device has become an indispensable key component of the laser obstacle removal system.

[0003] Traditional laser target calibration devices often employ manual visual aiming using telescopes or integrated cameras, which is inefficient and prone to calibration errors. Alternatively, they use a range-measuring laser emitting module and a range-measuring laser receiving module for calibration. However, these modules and the laser obstacle clearing device are relatively fixed, meaning the calibration is only effective for a fixed device. Accuracy decreases when the device is disassembled. Furthermore, outdoor obstacle clearing operations are complex, with temperature changes, air turbulence, and light interference causing laser beam drift. Existing calibration devices generally do not consider the impact of environmental interference on calibration accuracy, making dynamic real-time calibration impossible and severely affecting obstacle clearing reliability. Therefore, we propose a laser target calibration device for a laser obstacle clearing system to address these issues. Summary of the Invention

[0035] The bottom-spinning mechanism 2 includes a rotating bearing 21, which is fixedly fastened to the top of the device base 1. A mounting sleeve 22 is fixedly fastened to the middle of the rotating bearing 21. A mounting rod 23 is bolted into the mounting sleeve 22. The mounting base 4 is fixedly mounted on the top of the mounting rod 23. An internal gear ring 24 is fixedly mounted on the bottom of the mounting sleeve 22. A transmission gear 241 is meshed with the inner side of the internal gear ring 24. A fourth motor 242 is fixedly mounted on the inner side of the device base 1 near the transmission gear 241. The drive end of the fourth motor 242 and... The shaft end of the transmission gear 241 is fixedly installed. By turning on the fourth motor 242, the transmission gear 241 is driven to rotate the internal gear ring 24, thereby controlling the rotation of the mounting sleeve 22, the mounting rod 23 and the mounting base 4. This, in turn, controls the Z-axis rotation of the laser obstacle clearing transmitter 63 and the laser rangefinder 53, further adjusting the overall angular position of the laser obstacle clearing transmitter 63 and the laser rangefinder 53. This facilitates the laser obstacle clearing transmitter 63 to clear obstacles at different horizontal positions, improving the overall effectiveness of the laser obstacle clearing system.

[0036] The bottom of the device base 1 is provided with a mounting groove 801 corresponding to the support frame 8. The top of the support frame 8 is threaded into the corresponding mounting groove 801, which facilitates the installation and disassembly of the support frame 8. The entire device is supported by multiple support frames 8.

[0037] Working principle: Multiple support frames 8 are installed at the bottom of the device base 1 to support the entire device. Then, the second fixing frame 51 with laser rangefinder 53 is positioned between the second mounting frame 54 and the second locking frame 55. The second fastening screw 56 is rotated using a tool to control the second locking frame 55 to slide, so that the second locking frame 55 fixes the second fixing frame 51, thereby fixing the laser rangefinder 53. Subsequently, the second fixing frame 51 with the laser obstacle clearing device transmitter 63 is positioned and fixed between the first fixing frame 61 and the first mounting frame 64 in the same manner; Subsequently, the laser rangefinder 53 is used to calibrate the laser obstacle removal target point of the laser obstacle removal device transmitter 63, ensuring that the laser rangefinder 53 and the laser obstacle removal device transmitter 63 are coaxial. By turning on the first motor 723, the first worm gear 722 is driven to rotate the first worm wheel 724, the X-axis adjustment shaft 72, and the first fixed seat 721, thereby controlling the laser obstacle removal mechanism 6 to perform self-fine adjustment in the X-axis. By turning on the second motor 752, the second worm gear 751 is driven to rotate the second worm wheel 75, the Z-axis adjustment shaft 74, and the second fixed seat 741, thereby controlling the laser obstacle removal mechanism 6 to perform self-fine adjustment in the Z-axis, adjusting the relative angle between the laser obstacle removal device transmitter 63 and the laser rangefinder 53, ensuring that the laser rangefinder 53 and the laser obstacle removal device transmitter 63 are coaxial. During the adjustment process, auxiliary items can be found in the same environment to assist in obstacle clearing adjustment until the laser rangefinder 53 and the laser obstacle clearing transmitter 63 are coaxial. When the laser rangefinder 53 is needed for auxiliary laser ranging, the laser obstacle clearing transmitter 63 can accurately assist in obstacle clearing to ensure that the laser rangefinder 53 and the laser obstacle clearing transmitter 63 are coaxial, thereby improving the subsequent laser obstacle clearing effect of the laser obstacle clearing transmitter 63. The laser obstacle clearing device emitter 63 and laser rangefinder 53 can be finely adjusted by setting the adjustment mechanism 7. When the external environment is complex, auxiliary objects can be found in the same environment to assist in obstacle clearing adjustment until the laser rangefinder 53 can perform auxiliary laser ranging. The laser obstacle clearing device emitter 63 can accurately assist in obstacle clearing. The adjustment effect is relatively flexible and can flexibly adapt to different external environments. The relative angle between the laser obstacle clearing device emitter 63 and laser rangefinder 53 can be finely adjusted according to different environments. During subsequent laser obstacle removal, the third motor 352 can be activated to drive the third worm gear 351 to rotate the third worm wheel 35, thereby controlling the common drive shaft 341 to rotate, which in turn drives the two drive gears 34 to rotate synchronously. This, in conjunction with the arc rack 33, drives the gears 34 to mesh and connect, thereby controlling the arc rack 33 to drive the rotating frame 311 to rotate in the X-axis around the lifting shaft 321. This, in turn, controls the laser obstacle removal transmitter 63 and the laser rangefinder 53 to lift synchronously, and adjusts the overall angle and position of the laser obstacle removal transmitter 63 and the laser rangefinder 53, making it easier for the laser obstacle removal transmitter 63 to perform laser obstacle removal on obstacles at different heights. Simultaneously, by activating the fourth motor 242, the transmission gear 241 is driven to rotate the internal gear ring 24, thereby controlling the rotation of the mounting sleeve 22, mounting rod 23, and mounting base 4. This, in turn, controls the Z-axis rotation of the laser obstacle clearing transmitter 63 and the laser rangefinder 53, further adjusting the overall angular position of the laser obstacle clearing transmitter 63 and the laser rangefinder 53. This facilitates the laser obstacle clearing transmitter 63 in clearing obstacles at different horizontal positions, improving the overall effectiveness of the laser obstacle clearing system.
