Description

Technical Field

[0001] The utility model relates to the technical field of fluid loading and unloading arms, in particular to a vertical pipe of a land-based loading and unloading arm. Background Art

[0002] The crane arm, also known as the fluid loading and unloading arm, is mainly composed of fixed, rotating, operating, balancing and other mechanisms and oil pipes. Among them, the rotating mechanism (swivel joint) is carefully made of forged steel or aluminum alloy, with double-row ball bearings and stainless steel special sealing rings inside. It is flexible in rotation, reliable in sealing performance and durable. The balancing system has the form of counterweight, torsion spring, compression spring, tension spring and screw, as well as hydraulic and pneumatic balance, which can be operated with very little force. It is mainly used for loading and unloading liquid media in automobile tank cars, train tank cars or tank ships.

[0003] At present, the most common safety interlock device for land-based loading and unloading arms is the oil spill probe interlock valve. However, the oil spill detection device for land-based loading and unloading arms is often not manufactured by the same manufacturer as the land-based loading and unloading arms. The equipment matching degree between manufacturers is not high. The oil spill detection probe is often external. In daily operation, when the driver raises and lowers the crane pipe, the external oil spill probe will touch the pipe opening of the car tank truck. If the oil spill probe protection device cover is not installed firmly, it will bump against the oil spill probe, causing damage to the oil spill probe, increasing the equipment maintenance cost.

[0004] Aiming at the problem that the external oil spill probe of the crane pipe is prone to collision during use, resulting in damage to the external oil spill probe, a land-based loading and unloading arm drop pipe is needed to solve the above problem. Summary of the invention

[0005] Aiming at the problem that the external oil spill probe of the current crane pipe is prone to collision during use, resulting in damage to the external oil spill probe, the utility model proposes a land-based loading and unloading arm vertical pipe to solve the above problem.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a land-based loading and unloading arm vertical pipe, including a crane pipe body, a mounting groove is opened on the crane pipe body, an anti-oil spill probe installed on the crane pipe body is located on the inner side of the mounting groove, and a guard plate is installed on the inner lower part of the mounting groove. When in use, the anti-oil spill probe is located on the inner side of the mounting groove, which can effectively prevent the side of the anti-oil spill probe from being hit and damaged. The guard plate can prevent the bottom of the anti-oil spill probe from colliding, thereby further improving the protection effect of the anti-oil spill probe, and the overall use effect is good.

[0007] Furthermore, the mounting groove is in an arc shape.

[0008] Furthermore, the arc diameter of the mounting groove is 50 mm.

[0009] Furthermore, the number of the guard plates is at least 5.

[0010] Furthermore, the interval between two adjacent guard plates is 30 mm.

[0011] Furthermore, the uppermost guard plate is 300 mm away from the oil spill prevention probe.

[0012] The beneficial effects of the utility model are:

[0013] The vertical pipe of the loading and unloading arm is designed with a groove for the crane pipe, and the oil spill probe is placed in it to avoid damage to the oil spill probe due to collision when the crane pipe is retracted. At the same time, a protective plate is set on the outer wall of the vertical pipe to protect the oil spill probe while ensuring that the oil can pass normally without affecting the safety of the oil spill probe itself.
