[0002] The safety, stability, and precision of oil machinery and equipment are crucial in industries such as oil extraction, refining, and chemical processing. Oil machinery, in particular, is large and complex, making it difficult to transport as a whole. Instead, it must be disassembled, moved to the designated well site, and then reassembled. During this process, the traditional pin-and-lug fastening system for oil drilling rig equipment often suffers from insufficient positioning accuracy, cumbersome operation, poor stability, and difficulty inserting the pins through the lug holes. This makes it difficult to meet the demands of modern oil machinery for efficiency, safety, and reliability. Therefore, the development of a novel, fast, and precise device for positioning and installing drilling rig equipment and components is crucial. Utility Model Content

The utility model solves the problems of insufficient positioning accuracy, cumbersome operation, poor stability, and difficulty in inserting pins through ear plate holes in the current pin and ear plate fixing method used to connect various equipment of oil drilling rigs, and can effectively improve the installation efficiency and positioning accuracy of equipment and components related to oil drilling rigs.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for quickly and accurately positioning and installing concave and convex conical surfaces for oil drilling rigs, which includes a convex conical surface positioning block, a concave conical surface positioning block, a hexagonal head screw bolt with a hole, a hexagonal slotted nut, a cotter pin, a flat washer and a spring washer.
[0005] Furthermore, the concave cone surface positioning block and the convex cone surface positioning block are both provided with matching conical surfaces with the same taper, and the conical surfaces are both precisely machined to ensure a tight fit between the two.
[0006] Furthermore, the concave cone positioning block and the convex cone positioning block are both provided with bolt holes with matching positions on the conical surfaces, and the positions and sizes of the bolt holes are carefully designed to ensure that the bolts can firmly lock the concave cone positioning block and the convex cone positioning block.
[0007] The beneficial effects of this utility model are as follows: This utility model addresses the current situation where the pin-and-lug fixing method used to connect various equipment on oil drilling rigs suffers from insufficient positioning accuracy, cumbersome operation, poor stability, and difficulty in inserting the pins through the lug holes. By adopting a concave-convex conical surface structure, this utility model can achieve rapid and precise positioning and installation of oil drilling rig components, improving installation efficiency and positioning accuracy. Furthermore, this simple and reliable structure can ensure a secure connection of the installed components, effectively improving the installation efficiency and positioning accuracy of oil drilling rig-related equipment and components.

[0012] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0013] Please also refer to Figures 1 to 3 The following is a detailed description of the fast and accurate positioning and installation device for a concave and convex cone surface for a petroleum drilling rig according to an embodiment of the utility model in conjunction with the accompanying drawings.
[0014] like Figure 1 As shown, the concave-convex conical surface fast and accurate positioning and installation device for oil drilling rigs comprises a convex conical surface positioning block (1), a concave conical surface positioning block (2) that can closely match the conical surface of the convex conical surface positioning block, and a hexagonal head screw with a hole bolt (3), a spring washer (4), a flat washer (5), a hexagonal slotted nut (6) and a cotter pin (7) for locking the convex conical surface positioning block (1) and the concave conical surface positioning block (2).
[0015] Specifically, the convex conical surface positioning block (1) and the concave conical surface positioning block (2) are precisely machined, and the convex conical surface cooperates with the concave conical surface on the component to be installed, and vice versa.

During the installation process, when the two conical surfaces approach each other, they can automatically adjust their positions to achieve rapid positioning.
[0016] During implementation, welding is required for the first time at the drilling rig manufacturer. First, the components to be installed are hoisted to a predetermined position, and then the device is assembled together according to Figure (1). The concave cone surface positioning block (2) is welded to the oil drilling rig body, and the convex cone surface positioning block (2) is welded to the component to be installed. Furthermore, it is locked with a hexagonal head screw with a hole bolt (3), a spring washer (4), a flat washer (5), a hexagonal slotted nut (6) and a cotter pin (7).
