This design can accurately move the loading and unloading arm 103 to the optimal docking position according to specific needs, ensuring the smooth progress of the unloading process. It can also make the docking of the loading and unloading arm 103 and the discharge port of the tank truck more accurate, reducing the risk of leakage caused by position deviation, and improving the safety and reliability of unloading. When the loading and unloading arm 103 is adjusted, the loading and unloading arm 103 can be docked with the tank truck through the discharge joint 106. During docking, the spring balancer 105 can provide a pulling force that balances the gravity of the loading and unloading arm 103. The working principle of the spring balancer 105 is: when the loading and unloading arm 103 is in a stationary state, the spring balancer 105 inside The spring is in a stretched state, generating an upward pulling force, which is balanced with the gravity of the loading and unloading arm 103. At this time, the stretched length and pulling force of the spring are designed and adjusted to ensure that the weight of the loading and unloading arm 103 can be accurately balanced. When the operator lifts the loading and unloading arm 103 upward, the gravity of the loading and unloading arm 103 decreases, and the spring inside the spring balancer 105 will gradually shrink, reducing the upward pulling force to adapt to the change in the gravity of the loading and unloading arm 103. At the same time, the reel will rotate with the rise of the loading and unloading arm 103 to release a certain length of spring. On the contrary, when the operator lowers the loading and unloading arm 103 downward, the gravity of the loading and unloading arm 103 increases, and the spring inside the spring balancer 105 will be further stretched to increase the upward pulling force.The reel will also rotate in the opposite direction as the loading and unloading arm 103 descends, retracting a certain length of the spring.
