[0013] Compared with the prior art, this utility model provides a fully automatic alignment arm for loading and unloading tank trucks with an integrated sealing cover, which has the following advantages:

[0014] 1. The structural design of the automatic alignment loading arm includes the design of the first joint drive, the second joint drive and the third joint drive mechanism, which is conducive to the flexible operation of the automatic alignment loading arm and can achieve precise tank opening positioning. The liquid receiving hopper telescopic mechanism can realize the automatic recovery of residual liquid.

[0015] 2. By installing servo motors at multiple rotating joints of the loading arm, the loading arm can obtain driving force. The absolute value rotary encoder built into the servo motor can record the motor rotation angle in real time. There is a regular functional relationship between the motor rotation angle and the rotation angle when the automatic alignment loading arm moves. Through this relationship, the end of the automatic alignment loading arm can be precisely controlled so that the vertical tube reaches the designated position. Then, the sealing cover continues to descend under the action of the third joint drive mechanism. After the sealing cover contacts the tank opening, it will rise after a period of time. At this time, it drives the pressing limit plate to rise. The proximity switch transmits a signal, and the control system controls the third joint drive mechanism to stop pressing down. At this time, under the action of the spring, the sealing cover presses and seals the tank opening. At the same time, a gas phase pipeline is designed to recover the gas generated during loading and unloading, so as to achieve a sealed loading effect. Attached Figure Description
