Technical Field

[0001] This utility model relates to the field of oil drilling equipment technology, specifically to an adjustable support base for an oil drilling platform. Background Technology

[0002] Oil drilling platforms serve as support points for mounting drilling rigs and transmission equipment, and are the operating areas for drilling operations. However, during drilling, changes in loads such as drill string weight and mud circulation pressure can cause localized overloads on the platform. Therefore, it is necessary to adjust the height of the support points to regulate load distribution and prevent fatigue or collapse of the drilling rig structure. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing an adjustable support base for oil drilling platforms, which can adjust the support height of the oil drilling platform, thereby adjusting the load distribution of the drilling rig derrick and avoiding fatigue or collapse of the drilling rig derrick structure due to the inability to adjust the support point height.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable support base for an oil drilling platform includes an upper platform and a lower platform, an abutment assembly for connecting the upper and lower platforms, and multiple servo hydraulic cylinders. The servo hydraulic cylinders are fixed on the lower platform, and the piston rods of the servo hydraulic cylinders drive the upper platform vertically upward.

[0005] Furthermore, two slide rails are horizontally arranged on the lower platform; the abutting assembly includes a slide frame that slidably connects the two slide rails, an electric push rod for driving the slide frame to slide along the slide rails, and multiple abutting posts are arranged at the bottom of the upper platform, with an abutting platform arranged on the slide frame directly opposite the abutting posts.

[0006] Furthermore, the abutment platform is provided with multiple steps of different heights, and the steps are arranged in a stepped shape.

[0007] Furthermore, the cross-sectional shape of the abutment post is circular or square, and an abutment hole is provided on the step directly opposite the abutment post, the cross-sectional shape of the abutment hole being adapted to the abutment post.

[0008] Furthermore, a connecting frame is provided at the bottom of the lower platform, and a foot is provided at the bottom end of the connecting frame. The foot is provided with multiple connecting holes, and the foot is fixed to the ground by inserting a ground spike into the connecting holes.

[0009] The beneficial effects of this utility model are: In practical applications, the support height of the drilling rig derrick and transmission equipment on the upper platform is adjusted by extending and retracting the piston rods of multiple servo hydraulic cylinders, thereby adjusting the load distribution of the drilling rig derrick. The support stability after height adjustment is improved by the abutment component. This utility model can adjust the support height of the oil drilling platform, thereby adjusting the load distribution of the drilling rig derrick and avoiding fatigue or collapse of the drilling rig derrick structure due to the inability to adjust the height of the support points.

Detailed Implementation

[0011] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustable support base of the oil drilling platform includes an upper platform 1 and a lower platform 2, an abutment component 3 for connecting the upper platform 1 and the lower platform 2, and multiple servo hydraulic cylinders 4. The servo hydraulic cylinders 4 are fixed on the lower platform 2, and the piston rod of the servo hydraulic cylinder 4 drives the upper platform 1 vertically upward.

[0012] In use, the piston rods of multiple servo hydraulic cylinders 4 extend and retract to adjust the support height of the drilling rig derrick and transmission equipment on the upper platform 1, thereby adjusting the load distribution of the drilling rig derrick. The support stability after height adjustment is improved by the abutment component 3. This utility model can adjust the support height of the oil drilling platform, thereby adjusting the load distribution of the drilling rig derrick and avoiding fatigue or collapse of the drilling rig derrick structure due to the inability to adjust the height of the support points.

[0013] like Figure 1 , Figure 2 and Figure 3As shown, the lower platform 2 is horizontally provided with two slide rails 21; the abutment assembly 3 includes a slide 31 that slidably connects the two slide rails 21, and an electric push rod 32 for driving the slide 31 to slide along the slide rails 21. The bottom of the upper platform 1 is provided with multiple abutment posts 33, and an abutment platform 34 is provided on the slide 31 facing the abutment posts 33. In this embodiment, when the upper platform 1 needs to be raised, the piston rod of the servo hydraulic cylinder 4 extends vertically upward to the highest point, the electric push rod 32 drives the slide 31 to slide along the slide rails 21, so that the bottom of the abutment post 33 faces the abutment platform 34, the piston rod of the servo hydraulic cylinder 4 retracts until the bottom of the abutment post 33 abuts the abutment platform 34, and the raising of the upper platform 1 is completed.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, the abutment platform 34 is provided with multiple steps 341 of different heights, and the multiple steps 341 are in a stepped shape; in this embodiment, by adjusting the abutment column 33 to abut against the steps 341 of different heights, the upper platform 1 can be adjusted to different heights.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, the cross-sectional shape of the abutment post 33 is circular or square, and the step 341 is provided with an abutment hole 342 facing the abutment post 33. The cross-sectional shape of the abutment hole 342 is adapted to the abutment post 33. In this embodiment, when the upper platform 1 needs to be raised, the piston rod head of the servo hydraulic cylinder 4 extends vertically upward to the highest point, and the electric push rod 32 drives the slide 31 to slide along the slide rail 21, so that the bottom of the abutment post 33 faces the abutment hole 342 on the target height step 341. The piston rod head of the servo hydraulic cylinder 4 retracts until the bottom of the abutment post 33 is inserted into the abutment hole 342 on the abutment platform 34, thus completing the raising of the upper platform 1. The abutment hole 342 can improve the support stability of the upper platform 1 and the lower platform 2 after height adjustment.
