[0028] The utility model provides a kind of rotary arm type full-automatic crane pipe for the problems existing in prior art, including pedestal 1, lifting seat 3, first rotary arm 4, second rotary arm 5 and liquid injection pipe 6, lifting seat 3 and pedestal 1 slidingly connect, first rotary arm 4 is rotatably connected with lifting seat 3, second rotary arm 5 is rotatably connected with first rotary arm 4, liquid injection pipe 6 is rotatably connected with second rotary arm 5, threaded rod 2 is rotatably installed on pedestal 1, first motor 7 for driving threaded rod 2 is fixedly installed on pedestal 1, second gear ring 13 is fixedly installed on first rotary arm 4, third motor 12 for driving first rotary arm 4 is fixedly installed on lifting seat 3, first support arm 14 is fixedly installed on first rotary arm 4, electric push cylinder 8 for driving second rotary arm 5 is rotatably installed on first support arm 14, second support arm 15 is fixedly installed on second rotary arm 5, first gear ring 11 is fixedly installed on liquid injection pipe 6, second motor 9 for driving liquid injection pipe 6 is fixedly installed on second rotary arm 5;First motor 7 and threaded rod 2 are driven by bevel gear set, the rotation axis of third motor 12 is provided with straight tooth gear and is engaged with second gear ring 13, the rotation axis of second motor 9 is provided with straight tooth gear and is engaged with first gear ring 11, electric push cylinder 8 is slidingly connected with second support arm 15.

[0029] As a result, by the PLC control system and host computer drive electric push cylinder 8, second motor 9 and third motor 12, the information recorded by first rotary encoder 16 will be used to start third motor 12 to drive first rotary arm 4 to rotate corresponding angle by the engagement of straight tooth gear and second gear ring 13, and electric push cylinder 8 will be used to push second rotary arm 5 to rotate, and second motor 9 will be used to drive liquid injection pipe 6 to rotate, so that liquid injection pipe 6 can be aligned with the liquid injection port of the vehicle, achieving full-automatic adjustment and facilitating use.

[0030] First rotary encoder 16 is fixedly installed on lifting seat 3;The rotation axis of first rotary encoder 16 is provided with straight tooth gear and is engaged with second gear ring 13, third gear ring 18 is fixedly installed on second rotary arm 5, and second rotary encoder 17 is fixedly installed on first rotary arm 4;The rotation axis of second rotary encoder 17 is provided with straight tooth gear and is engaged with third gear ring 18, third rotary encoder 19 is fixedly installed on second rotary arm 5;The rotation axis of third rotary encoder 19 is provided with straight tooth gear and is engaged with first gear ring 11, and camera 21 is installed on pedestal 1.

[0031] In summary, when the camera 21 identifies a strange license plate, it will switch to manual mode. In manual mode, the operator will manually adjust the position between the first rotary arm 4, the second rotary arm 5 and the liquid injection pipe 6, so that the liquid injection pipe 6 can be aligned with the liquid injection port of the transport vehicle.

After the PLC control system and the host computer receive the data, they will match and record the license plate information taken by the camera 21, achieving the effect of intelligent learning and recording the positions of different vehicle liquid injection ports.

[0032] Working principle:

[0033] First, during installation, the first motor 7, the electric cylinder 8, the second motor 9, the third motor 12, the first rotary encoder 16, the second rotary encoder 17, the third rotary encoder 19 and the camera 21 are connected to the PLC control system and the host computer.

Similarly, the second rotary encoder 17 will record and upload the rotation data of the second rotary arm 5 relative to the first rotary arm 4, and the third rotary encoder 19 will record and upload the rotation data of the liquid injection pipe 6 relative to the second rotary arm 5. After the PLC control system and the host computer receive the data, they will match and record the license plate information taken by the camera 21.

[0034] Secondly, when the vehicle carrying the license plate recorded next time comes again, the camera 21 will start the automatic mode after recognizing the license plate information, and will drive the electric push cylinder 8, the second motor 9 and the third motor 12 through the PLC control system and the upper computer, and will start the third motor 12 to drive the first rotating arm 4 to rotate the corresponding angle (the first rotating encoder 16 will control the rotating angle of the first rotating arm 4 in the automatic mode) through the meshing of the straight tooth gear and the second gear ring 13 according to the information (forward or reverse) recorded by the first rotating encoder 16, and the electric push cylinder 8 will start to push the second rotating arm 5 to rotate (the second rotating encoder 17 controls the rotating angle of the second rotating arm 5), and the second motor 9 will drive the liquid injection pipe 6 to rotate (the third rotating encoder 19 controls the rotating angle of the liquid injection pipe 6), so that the liquid injection pipe 6 can be aligned with the liquid injection port of the vehicle, and the effect of automatic position adjustment is realized.
