[0002] With the development of the oil industry, the overall transportation requirements for oil drilling equipment have become more stringent for shallow wells and medium-deep wells that require frequent transportation. As my country's oil equipment goes abroad, many important international oil producing areas require oil drilling equipment to have long-distance transportation performance when bidding for my country's oil equipment, and put forward higher requirements on load and structure.

[0003] When the oil equipment drilling rig derrick is moved as a whole, a large wheelbase axle structure is required. However, the large wheelbase axle has a long total length and is an integrated structure. Its structure has many disadvantages in manufacturing and use, such as:

[0004] 1. Long axles must be machined using large cutting equipment, which makes it very difficult to clamp and hoist the parts, and the cutting process is high in intensity and difficult;

[0005] 2. The axle is welded into a whole from different materials, which brings great difficulty to the processing before and after welding;

[0006] 3. Since the axle is welded from different materials, it is inconvenient and costly to repair;

[0007] 4. There are reliability issues in the assembly structure of the rim and tire;

[0008] 5. The connection structure between the half-axle assembly and the transport axle has no anti-shear effect and low connection strength. The transport axle is subjected to the shear effect of load strength during operation, especially for the transport axle with larger tonnage. The existing connection structure between the half-axle assembly and the transport axle, which is connected solely by bolts, poses a safety risk. Utility Model Content
