[0050] The side wall of the carrying platform 1 is provided with a docking assembly 11. The bottom of the unmanned aerial vehicle body 1 is provided with a positioning rod 21 corresponding to the docking assembly 11. The docking assembly 11 comprises a fixed plate 111 connected with the side wall of the carrying platform 1. A lock box 12 is arranged at the top end of the fixed plate 111. A limiting sleeve 13 is arranged at the top of the lock box 12. A movable frame 14 is arranged at the top end of the limiting sleeve 13. A movable block 141 is movably arranged in the movable frame 14. A through hole corresponding to the limiting sleeve 13 is formed in the movable block 141. A conical guide cylinder 142 is arranged above the through hole at the top end of the movable block 141. An electromagnet 143 is arranged on the inner side wall of the movable frame 14. The electromagnet 143 is arranged in a four-pole array, i.e. four permanent magnets are arranged in an alternating manner in terms of magnetization direction (N / S pole).

[0051] Further, the inner wall of the movable frame 14 is provided with a limiting shaft 145 near the four corners, the limiting shaft 145 is provided with an extension rod 146 and is rotatably connected with the rotating connection end 1461 of the extension rod 146, the movable connection end 1462 of the extension rod 146 is rotatably connected with the side wall of the movable block 141, and the extension rod 146 can ensure the movement of the movable block 141 in the horizontal plane and limit the Z-axis direction.

[0056] The unmanned aerial vehicle is guided by the navigation system to land on the docking platform, the spherical end 211 contacts the inner side wall of the conical guide cylinder 142, the unmanned aerial vehicle continues to descend or relies on its own gravity to press down to automatically correct to the center position, the movable block 141 moves to a position directly below the positioning rod 21, until the spherical end 211 completely enters the through hole of the movable block 141, whether the spherical end 211 completely enters the through hole of the movable block 141 can be judged by the position sensor inside the through hole, after completely entering, the electromagnet 143 is powered on to generate a repulsive force between the electromagnet 143 and the permanent magnet 144, which can push the movable block 141 to the center position of the movable frame 14, so that the unmanned aerial vehicle can continue to descend, the positioning rod 21 can enter the inside of the limiting sleeve 13, and the repulsive force between the electromagnet 143 and the permanent magnet is slowly increased by gradually increasing the current of the electromagnet, so as to slowly correct the unmanned aerial vehicle body 2 to accurately enter the docking position.

[0057] The positioning rod 21 enters the limiting sleeve 13 and continues to descend until the pressure sensor detects that the positioning rod lands on the bottom of the lock box 12, at this time, the electric control lock tongue is clamped and locked with the lock hole 212 by the controller, at this time, the limiting of the unmanned aerial vehicle in the vertical direction and the rigid locking of the circumference are completed, so that the unmanned aerial vehicle is firmly combined with the ground platform as a whole, and any shaking is eliminated.

[0058] The first baffle plate 331 is rotationally connected to both ends of the object table 33, and is in a horizontal state in the initial state when the object table 33 is located on the carrying platform 1. The second baffle plate 332 is rotationally connected to both sides of the object table 33, and is in an initial state of being inclined at a certain angle. The first rotating shaft 3311 is rotationally connected to both ends of the object table 33. The first baffle plate 331 is fixedly connected to the first rotating shaft 3311. The second rotating shaft 3321 is rotationally connected to the side wall of the connecting frame 333. The second baffle plate 332 is fixedly connected to the second rotating shaft 3321. The second baffle plate 332 has an L-shaped cross section. The side end of the first rotating shaft 3311 is provided with a worm wheel 3312. The side wall of the connecting frame 333 is provided with a worm gear 334. The worm gear 334 is meshingly connected to the worm wheel 3312. The side end of the worm gear 334 is provided with a gear wheel 3341. The side wall of the carrying platform 1 is provided with a toothed rail 15. The toothed rail 15 is meshingly connected to the gear wheel 3341. The first rotating shaft 3311 is provided with an incomplete bevel gear 3313. The side end of the second rotating shaft 3321 is provided with a bevel gear 3322. The bevel gear 3322 is meshingly connected to the incomplete bevel gear 3313.

[0059] When the object table 33 is located on the carrying platform 1, the standard box is conveyed to the object table 33 by the conveying assembly 4. The controller controls the electrically controlled lock tongue to be unlocked, and controls the unmanned aerial vehicle to ascend. In the process of vertical ascent of the unmanned aerial vehicle, the meshing connection between the toothed rail 15 and the gear wheel 3341 can drive the worm gear 334 to rotate. The meshing connection between the worm gear 334 and the worm wheel 3312 can drive the first rotating shaft 331 to rotate. In the rotating process of the two first baffle plates 331, the standard box can be centered and moved. At this time, the first baffle plate 331 continues to rotate. The meshing connection between the bevel gear 3322 and the incomplete bevel gear 3313 drives the second baffle plate 332 to rotate. Then, the first baffle plate 331 and the second baffle plate 332 clamp and fix the standard box at the same time. It is worth mentioning that the second baffle plate 332 is L-shaped, and simultaneously limits the standard box in the vertical direction.

[0060] Working principle: autonomous landing and preliminary positioning: the unmanned aerial vehicle is roughly landed near the carrying platform under the guidance of the navigation system. The spherical positioning rod at the bottom of the unmanned aerial vehicle first contacts the conical guide cylinder on the docking assembly;

[0061] Flexible correction and accurate positioning:

[0062] The unmanned aerial vehicle continues to descend. The gravity of the unmanned aerial vehicle acts on the conical guide cylinder through the spherical end head, forcing the movable block to move horizontally, and automatically correcting the positioning rod to the center position.

[0063] When the position sensor detects that the spherical end head of the positioning rod completely enters the through hole of the movable block, the system is powered on. The repulsive force generated by the electromagnet and the permanent magnet accurately pushes the movable block to the center of the movable frame in a flexible manner from small to large, so that the positioning rod can vertically enter the limiting sleeve below.

[0064] Rigid locking and platform combination: the positioning rod continues to descend until its bottom end touches the pressure sensor at the bottom of the lock box. At this time, the controller immediately triggers the electric control lock tongue to pop out and engage with the lock hole on the positioning rod. This completes the positioning of the UAV in the vertical direction and the rigid locking in the circumferential direction, making the UAV and the carrying platform firmly combined as a whole, eliminating the shaking;

[0065] Automatic loading of goods: after the UAV is locked, the conveying assembly transports the standard box to the loading platform;

[0066] Air clamping and take-off transfer: after the goods are loaded, the controller controls the electric control lock tongue to unlock, and the UAV takes off vertically. During the take-off process, the rack fixed on the side wall of the carrying platform drives the gear on the loading platform to rotate, and then drives the first rotating shaft to rotate through the worm-gear transmission. First stage (centering): the first rotating shaft drives the two first baffles on the sides to rotate inward, pushing the standard box to the center to achieve automatic centering.

[0067] Second stage (clamping and limiting): the first rotating shaft continues to rotate and engages with the bevel gear on the second rotating shaft through the incomplete bevel gear on it, starting to drive the two L-shaped second baffles on the sides to rotate inward. Finally, the first baffle and the second baffle act simultaneously to clamp and fix the standard box from the horizontal and vertical directions, ensuring its stability during air transportation.

[0068] Working principle: move the drilling assembly to the position where drilling is needed, then insert the top end of the fixed rod 2 into the output end of the drive motor 331, rotate the threaded rods 3321 respectively, and move the sliding block 3322 to the innermost position. At this time, the four limiting arc plates 34 can be spliced into a limiting ring. The rolling balls 342 on the limiting arc plates 34 are in rolling connection with the second limiting groove 201. The limiting structure increases the connection strength of the drilling assembly and the fixed rod 2 while reducing the friction between the limiting structure and the fixed rod 2. In addition, the limiting of the drilling assembly on the fixed rod 2 can be released by reversing the threaded rods 3321, which facilitates the replacement of the metal drill bit.

[0069] Place the metal pipe to be processed on the first arc-shaped fixed plate 414 and the second arc-shaped fixed plate 424 by hoisting equipment, support the metal pipe to be processed by the first arc-shaped fixed plate 414 and the second arc-shaped fixed plate 424, and start the second motor 423 at this time. By screwing the second threaded rod 422 with the fixed vertical plate 42, the moving vertical plate 42 can be driven to move towards the fixed vertical plate 41. The moving vertical plate 42 abuts against the side end of the metal pipe, pushing the other end of the metal pipe into the three-jaw centering chuck 411. At this time, the metal pipe to be processed is fixed.

[0070] When drilling, the cooling liquid continuously flows into the hole bottom through the guide channel 12, and after cooling, the cooling liquid is discharged along with the cutting, so as to realize cooling.
