[0024] The effect achieved by the entire Embodiment 1 is that when the loading arm is telescoped, the electric telescopic rod 304 is activated. The electric telescopic rod 304 is fixedly arranged on the end face of the mounting sleeve 303. When its telescopic end extends outward, it will push the connecting sleeve 305, thereby driving the inner pipe 302 to extend outward from the inside of the outer pipe 301. The mounting ring block 306 fixedly connected to the outer surface of the inner pipe 302 slides synchronously on the inner surface of the outer pipe 301. At the same time, an annular piston 307 is arranged on the outer surface of the connecting ring block 308 fixedly connected to its end face and slides synchronously on the inner surface of the outer pipe 301, so that the inner pipe 302 remains sealed when extending outward. After the inner pipe 302 extends outward to the required distance, adjust the positions of multiple branch pipes according to the loading position. Hold the first branch pipe 701 and rotate it so that it rotates on the inner surface of the inner pipe 302. Hold the second branch pipe 702 and rotate it so that it rotates on the outer surface of the first branch pipe 701. Hold the third branch pipe 703 and rotate it so that it can rotate on the outer surface of the second branch pipe 702. Dock the joint 704 with the material receiving port of the loading and unloading vehicle. Driven by the electric telescopic rod 304, the inner pipe 302 is driven to extend outward, playing a role in adjustment. The entire loading arm can be appropriately adjusted according to different working conditions, and the extension length of the entire loading arm is adjusted to avoid the parking position being irregular caused by the freight driver, resulting in the connection port exceeding the extension distance of the loading arm, thereby improving the connection efficiency of liquid materials.

[0025] Embodiment 2: As Figures 1 - 5 shown, a first mounting block 4 is fixedly connected to a position on the outer surface of the outer pipe 301 far from the main pipe body 1, a second mounting block 6 is fixedly connected to a position near the middle on the outer surface of the main pipe body 1, and a support rod 5 is fixedly connected between the first mounting block 4 and the second mounting block 6.

[0026] The effect achieved by the entire Embodiment 2 is that during use, by fixedly connecting the first mounting block 4 and the second mounting block 6 between the outer surface of the outer pipe 301 and the outer surface of the main pipe body 1 respectively, and fixedly connecting a support rod 5 between the first mounting block 4 and the second mounting block 6, it plays a role in supporting the outer pipe 301, preventing the connection between the outer pipe 301 and the main pipe body 1 from breaking due to its outward extension during the operation of the loading arm, and has high practicability.

[0027] Working principle: When in use, first fix it at the working location of the loading arm through the base 2, dock the storage device with the connecting pipe 8 through the conveying pipe. According to the extension requirement of the loading arm, start the electric telescopic rod 304. The electric telescopic rod 304 is fixedly arranged on the end face of the mounting sleeve 303. When its telescopic end extends outward, it will push the connecting sleeve 305, thereby driving the inner pipe 302 to extend outward from the inside of the outer pipe 301. The mounting ring block 306 fixedly connected to the outer surface of the inner pipe 302 slides synchronously on the inner surface of the outer pipe 301. At the same time, an annular piston 307 is arranged on the outer surface of the connecting ring block 308 fixedly connected to its end face and slides synchronously on the inner surface of the outer pipe 301, so that the inner pipe 302 remains sealed when extending outward. After the inner pipe 302 extends outward to the required distance, adjust the positions of multiple branch pipes according to the loading position. Hold the first branch pipe 701 and rotate it to make it rotate on the inner surface of the inner pipe 302. Hold the second branch pipe 702 and rotate it to make it rotate on the outer surface of the first branch pipe 701. Hold the third branch pipe 703 and rotate it to make it rotate on the outer surface of the second branch pipe 702. Dock the joint 704 with the material receiving port of the loading and unloading vehicle. Driven by the electric telescopic rod 304, drive the inner pipe 302 to extend outward, which plays an adjusting role. The whole loading arm can be appropriately adjusted according to different working conditions, and the extension length of the whole loading arm can be adjusted to avoid the situation that the parking position is not standardized by the freight driver, resulting in the connection port exceeding the extension distance of the loading arm. By fixedly connecting the first mounting block 4 and the second mounting block 6 between the outer surface of the outer pipe 301 and the outer surface of the main pipe body 1 respectively, and fixedly connecting a support rod 5 between the first mounting block 4 and the second mounting block 6, it plays a supporting role for the outer pipe 301, preventing the connection between the outer pipe 301 and the main pipe body 1 from breaking due to its outward extension during the work of the loading arm, and has high practicability.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
