[0013] When the train arrives under the support frame, the rotating seat controls the connecting arm to rotate, and the connecting mechanism faces the trestle escalator and is fixed to the train by the suction plate. After suction, the positioning detector determines whether it is sucked tightly, and the crane pipe gun head passes through the annular hole at the limit frame and is clamped with the clamping frame, and the position detector detects whether the clamping position of the gun head meets the clamping requirements. When the clamping requirements are met, the crane pipe transports oil. After the oil transportation is completed, the gun head is pulled out of the limit frame. After the position detector detects that the gun head has left, it transmits a signal to the positioning detector, and then the suction plate no longer adsorbs the train. This method effectively avoids damage to the crane pipe caused by external force due to manual forgetting to pull out the crane pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The surface of the rotating rod 5 is provided with an external thread, and the interior of the collar 3 is provided with an internal thread, and the rotating rod 5 is thread-matched with the collar 3. Through the thread engagement transmission, the transmission process is more stable.

[0032] When the train arrives under the support frame 6, the rotating seat 12 controls the connecting arm to rotate, and the connecting mechanism 7 faces the trestle escalator and is fixed to the train by the suction plate 13. After being sucked, it is determined whether it is sucked tightly through the positioning detector 15, and the crane pipe gun head passes through the annular hole at the limit frame 16 and is clamped with the clamping frame 18, and the position detector 17 is used to detect whether the clamping position of the gun head meets the clamping requirements. When the clamping requirements are met, the crane pipe transports oil. After completing the oil transportation, the gun head is pulled out of the limit frame 16. After the position detector 17 detects that the gun head has left, it transmits a signal to the positioning detector 15, and then the suction plate 13 no longer adsorbs the train; this method effectively avoids damage to the crane pipe caused by external force due to manual forgetting to pull out the crane pipe.
