Technical Field

[0001] This utility model relates to the field of auxiliary equipment for oilfield operations, and in particular to a double-layer operating platform for minor oilfield repairs. Background Technology

[0002] In oilfield operations, blowout preventers are added to avoid reservoir contamination caused by mud kills or surface pollution caused by blowout reduction and depressurization. This necessitates that workers leave the surface to operate the equipment, requiring a work platform. Currently, most oilfield work equipment uses a fixed, integrated platform design with a fixed height that cannot be adjusted to meet specific needs. Furthermore, oilfield maintenance operations are often short-term, and the specific conditions vary from oilfield to oilfield, making fixed work platforms inconvenient. Therefore, a double-layered work platform for oilfield maintenance is needed to meet these operational requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a double-layer working platform for minor oilfield repairs, which can adapt to different working heights and meet the operational needs of different oilfields.

[0004] To achieve the above objectives, this utility model provides a double-layer working platform for minor oilfield repairs, including a fixed support, a first lifting assembly on the fixed support, a first working platform on the first lifting assembly, a second lifting assembly on the top of the first working platform, and a second working platform on one side of the second lifting assembly.

A rotating rod is connected to the first rotating shaft, and a second hydraulic cylinder is provided at the bottom of the rotating rod.

[0009] Preferably, the bottom end of the second hydraulic cylinder is provided with a support seat, and a rotating seat is provided inside the support seat. The bottom end of the second hydraulic cylinder is connected to the rotating seat, and the rotating seat is connected to the support seat through a second rotating shaft.

[0010] Preferably, a rotating frame is fixedly provided at the bottom of the rotating rod, and a third rotating shaft matching it is provided inside the rotating frame, with the top of the second hydraulic cylinder hinged to the third rotating shaft.

[0024] Example 1

[0025] like Figure 1-4 As shown, this utility model provides a double-layer working platform for minor oilfield repairs, including a fixed support frame. The fixed support frame includes four support columns 1, and connecting rods 2 are provided between adjacent support columns 1. The connecting rods 2 ensure the overall stability of the fixed support frame. A first lifting assembly is provided on the fixed support frame, and a first working platform 6 is provided on the first lifting assembly. The first lifting assembly includes a lifting groove 3, and the lifting groove 3 is provided on the inner side of the support columns 1.

[0026] A first hydraulic cylinder 4 is located at the bottom of the lifting trough 3, and a connecting seat 5 is located at the top of the first hydraulic cylinder 4. A first working platform 6 is fixed on the connecting seat 5. The lifting and lowering of the first hydraulic cylinder 4 can drive the connecting seat 5 to rise and fall, thereby changing the working height of the first working platform 6. There are four first hydraulic cylinders 4 and four connecting seats 5, and the first hydraulic cylinders 4 are symmetrically arranged in pairs. The four first hydraulic cylinders 4 operate synchronously during operation, which allows the first working platform 6 to rise and fall horizontally.

[0027] The first working platform 6 is equipped with a second lifting assembly at its top. The second lifting assembly includes a first rotating shaft 7, which is fixed to the upper surface of the first working platform 6 by a rotating shaft bracket 8. A rotating rod 9 is connected to the first rotating shaft 7, and a second hydraulic cylinder 17 is provided at the bottom of the rotating rod 9. The second hydraulic cylinder 17 can push the rotating rod 9 to rotate around the first rotating shaft 7, thereby changing the height of the end of the rotating rod 9.

[0028] The second hydraulic cylinder 17 has a support base 10 at its bottom end, and a rotating seat 11 is provided inside the support base 10. The bottom end of the second hydraulic cylinder 17 is connected to the rotating seat 11, and the rotating seat 11 is connected to the support base 10 through a second rotating shaft 15. Thus, the rotating seat 11 can rotate inside the support base 10, and the second hydraulic cylinder 17 rotates with the rotating seat 11.

[0029] A rotating frame 21 is fixedly mounted at the bottom of the rotating rod 9. A matching third rotating shaft 20 is located inside the rotating frame 21. The top of the second hydraulic cylinder 17 is hinged to the third rotating shaft 20, allowing the second hydraulic cylinder 17 to rotate around the rotating frame 21. When the second hydraulic cylinder 17 extends, the normal rotation of the rotating rod 9 is ensured. This guarantees both the normal rotation of the rotating rod 9 and its supporting stability.

[0030] A second working platform 13 is provided on one side of the second lifting assembly. The second working platform 13 can move with the rotating rods 9. There are two rotating rods 9, and a worktable hanger 12 is provided between the two rotating rods 9. The worktable hanger 12 is triangular to ensure the overall stability of the structure. A round rod 18 is provided at the tip of the worktable hanger 12, and a wheel 14 is hinged to the round rod 18. The second working platform 13 is provided at the bottom of the wheel 14.

[0031] The center of gravity of the second work platform 13 is located below the rotating wheel 14. When the rotating rod 9 rotates and raises the height of the end of the rotating rod 9, because the second work platform 13 is hinged to the workbench hanger 12, the second work platform 13 can adjust its horizontal state by itself under the action of gravity. After the second work platform 13 is raised and lowered to the specified height, the second work platform 13 can maintain a horizontal state parallel to the ground.

[0032] The second working platform 13 is connected to the rotating rod 9 on both sides by elastic rods 19. During the raising and lowering of the second working platform 13, the second working platform 13 will shake, which may make the workers feel unsafe. The elastic rods 19 can effectively reduce this shaking and ensure the safety of the workers' installation work.

[0033] The second working platform 13 is equipped with a control unit 16, which is electrically connected to the first hydraulic cylinder 4 and the second hydraulic cylinder 17. The operator can control the ground clearance of the first working platform 6 and the second working platform 13 through the control unit 16 to achieve the required working height.

[0034] Therefore, this utility model adopts the above-mentioned double-layer working platform for minor oilfield repairs. It has a simple structure, can adapt to different working heights, and meets the operational needs of different oilfields.

[0035] It is worth noting that all the contents not described in detail in this utility model are existing technologies and are well known to those skilled in the art.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
