Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of petroleum exploration, in particular to an integrated rim with a rolled structure without an annular weld. Background Art
[0002] The complex road conditions and harsh environments of deserts and Gobi deserts pose significant challenges to the transportation of exploration equipment and the supply of materials. A series of desert transport vehicles with superior off-road capabilities and high speeds are currently the main mode of transportation.
[0003] The rim, as the most important device that directly contacts the ground, is becoming increasingly important in terms of strength, sealing performance, manufacturing process, and ease of replacement. In the existing technology, traditional rims are heavy, have many welds, are prone to air leakage, and have complex processes. Therefore, it is necessary to develop a high-strength, good-sealing rim specifically for desert vehicles. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an integrated rim with a rolled structure without annular welds. The rim is made of standard special materials for automobile rims, hot-rolled according to the special dimensions of the rim, and then rolled into a cylindrical structure using special equipment. The rim is hot-rolled in one step and has no conventional welding structure, thereby fundamentally avoiding the phenomenon of air leakage during use of the rim. At the same time, after using the profile, the force-applying parts are thickened and the unimportant parts are thinned, thereby increasing the load-bearing capacity of the rim and reducing the weight and heat dissipation performance of the rim.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] An integrated, annular weld-free rolled structure rim comprises a rim body which is annular in design and consists of a retaining ring segment, a center segment and a rim seat. The retaining ring segment is arranged on the left side of the center segment, and the rim seat is arranged on the right side of the center segment.
[0007] Preferably, a rim groove is provided on the outer wall of the central section, and a locking ring groove is provided on the outer wall of the rim seat.
[0008] Preferably, a locking ring is installed in the locking ring groove, and the locking ring cooperates with the locking ring groove.
[0009] Preferably, a retaining ring is provided on the locking ring, and a web body is installed on the inner wall of the rim body.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. We select 400LW, a standard material specifically for automotive rims, and hot-roll it to the rim's specific dimensions, including the retaining ring and groove dimensions. Then, we use specialized equipment to roll it into a cylindrical structure. Because this is a one-step hot-rolling process, without conventional welding, air leakage during use is fundamentally avoided.
[0012] 2. The original steel plate profile material is of uniform thickness, heavy weight, many welds, easy to leak, and complex process. After changing to profiles, the stress-applying areas are thickened and the unimportant areas are thinned, which increases the load-bearing capacity of the steel ring and reduces the weight and heat dissipation performance of the steel ring.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Reference Figure 1-4, an integrated annular weld-free rolled structure rim, including a rim body 3, the rim body 3 is annular in design, and the rim body 3 is composed of a retaining ring segment 301, a center segment 302 and a rim seat 303. The rim body 3 is made of standard automobile rim special material 400LW, and is hot-rolled according to the special size of the rim, including the retaining ring 1, the rim groove 304 and other sizes, and then rolled into a cylindrical structure using special equipment. The retaining ring segment 301 is arranged on the left side of the center segment 302, and the rim seat 303 is arranged on the right side of the center segment 302. The outer wall of the center segment 302 is provided with a rim groove 304, and the outer wall of the rim seat 303 is provided with a locking ring groove 305. A locking ring 2 is installed in the locking ring groove 305, and the locking ring 2 cooperates with the locking ring groove 305. The retaining ring 1 is provided on the locking ring 2, and the web body 4 is installed on the inner wall of the rim body 3.
[0020] When the utility model is used, a standard automobile rim special material 400LW is selected, and the special size of the rim body 3, including the size of the retaining ring 1, the rim groove 304 and the like, is hot-rolled and then rolled into a cylindrical structure using special equipment. The one-time hot-rolling is adopted without a conventional welding structure, which fundamentally avoids the leakage of the rim body 3 during use. After the profile is changed, the force-applying parts are thickened and the unimportant parts are thinned, thereby enhancing the load capacity of the steel rim and reducing the weight and heat dissipation performance of the steel rim. During use, the size is reasonable and the strength is sufficient to meet the use requirements. Moreover, when the desert vehicle is frequently inflated and deflated, the sealing performance is good, thus achieving the design purpose very well.
[0021] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
