Description

Technical Field

[0001] This utility model belongs to the field of oilfield equipment transfer, specifically, it relates to a flipping device for oilfield blowout preventers. Background Technology

[0002] In oilfield drilling operations, blowout preventers (BOPs) are core equipment in the well control system, and their regular maintenance and inspection require frequent flipping operations. Traditional methods typically employ two techniques: one is flipping using hoisting equipment and manual binding, which suffers from low operational efficiency (each flipping takes 40-60 minutes) and high safety risks (historically, serious accidents have occurred in oilfields due to broken slings); the other is using a simple clamp and hydraulic push rod flipping device. For example, Chinese Patent CN202212889U discloses a BOP flipping device, including a base with a support on the base, a rotating arm movably connected to the support, and a rotation control device connected to the rotating arm. The rotation control device is located on the base and can place the BOP inside the rotating arm, controlling its flipping.

[0003] However, these devices generally suffer from drawbacks such as inconvenient clamping operation and poor versatility. In actual production, existing technologies involve hoisting, tilting, and transfer processes, requiring the coordinated use of multiple machines such as overhead cranes, tilting machines, and transfer vehicles. This requires multiple operators, is time-consuming and labor-intensive, and poses safety hazards during the hoisting process.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a reversing device for oilfield blowout preventers. This invention is achieved through the following technical solution:

[0006] A tipping device for an oilfield blowout preventer includes a connecting frame mounted on the power arm of a loader. Each side of the connecting frame is provided with a clamping part, which are arranged opposite to each other. A power unit is mounted on the connecting frame for controlling the clamping parts to move opposite to each other to clamp the blowout preventer.

[0007] Preferably, the clamping part includes a clamp and a fixing pin, the fixing pin is fixedly installed at one end of the connecting frame, and the clamping part is slidably disposed on the fixing pin.

[0010] The support base is connected to the power unit, and the power unit pushes the support base to drive the clamp to slide on the fixed pin;

[0011] The clamps on both sides of the connecting frame are provided with opposing clamping plates, which hold the blowout preventer.

[0012] Preferably, the side of the clamp used to hold the blowout preventer is provided with an arc-shaped clamping surface.

[0013] Preferably, the power unit includes a hydraulic cylinder fixedly mounted on the connecting frame, the piston rod of the hydraulic cylinder being connected to the clamping part, controlling the clamping part to move in opposite directions to clamp the blowout preventer.

[0014] Preferably, the connecting frame includes at least an upper beam and a lower beam arranged in parallel, and two sets of mounting components are symmetrically arranged on both sides of the upper beam and the lower beam. The mounting components include an outer plate and an inner plate arranged sequentially from the ends of the upper beam and the lower beam toward the inside.

[0015] A clamping part is slidably provided between the outer plate and the inner plate.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1 – Figure 6 As shown, this embodiment provides a tilting device for an oilfield blowout preventer, including a connecting frame 4 installed on the power arm 2 of a loader. Each side of the connecting frame 4 is provided with a clamping part 5, which are arranged opposite to each other. A power unit is installed on the connecting frame 4 to control the clamping parts 5 to move opposite to each other to clamp the blowout preventer 1.

[0032] By coordinating the symmetrically arranged clamping parts 5 with the power unit, the blowout preventer 1 can be automatically centered and clamped. This can significantly improve work efficiency compared to traditional manual operation, while avoiding the risk of wire rope breakage during hoisting operations. It also simplifies the operation steps, allowing a single person to operate the loader to complete the unloading, flipping, and transfer of the blowout preventer 1, thus improving efficiency and safety.

[0033] The clamping part 5 includes a clamp 51 and a fixing pin 52. The fixing pin 52 is fixedly installed at one end of the connecting frame 4, and the clamping part 5 is slidably disposed on the fixing pin 52. The fixing pin 52 achieves a sliding fit, forming a high-precision linear guide mechanism.

[0034] The clamp 51 includes a clamping plate 511, a support base 512, an ear plate 513, and a stiffening plate 514;

[0035] The ear plate 513 has a sliding hole corresponding to the fixing pin 52. The ear plate 513 is sleeved on the fixing pin 52 through the sliding hole. The ear plate 513 and the clamping plate 511 are arranged perpendicularly. A support seat 512 is provided on the side of the ear plate 513 facing the power unit, and a stiffener 514 is provided on the other side.

[0036] The support base 512 is connected to the power unit, and the power unit pushes the support base 512 to drive the clamp 51 to slide on the fixing pin 52;

[0037] The clamps 51 on both sides of the connecting frame 4 are provided with opposing clamping plates 511, which clamp the blowout preventer 1.

[0038] By vertically arranging the ear plate 513 and the clamping plate 511 to form an L-shaped anti-bending structure, the bending strength is improved, and the support effect is further improved by arranging the stiffening plate 514.

[0039] Preferably, the clamping plate 511 has an arc-shaped clamping surface on one side for clamping the blowout preventer 1. The arc-shaped clamping surface forms a surface contact with the outer diameter of the blowout preventer 1, improving the clamping effect and providing a larger clamping range.

[0040] Furthermore, the power unit includes a hydraulic cylinder 6 fixedly mounted on the connecting frame 4. The piston rod of the hydraulic cylinder 6 is connected to the clamping part 5, which controls the clamping part 5 to move in opposite directions to clamp the blowout preventer 1.

[0041] Preferably, the connecting frame 4 includes at least an upper beam 41 and a lower beam 42 arranged in parallel, and two sets of mounting components are symmetrically arranged on both sides of the upper beam 41 and the lower beam 42. The mounting components include an outer plate 43 and an inner plate 44 arranged sequentially from the ends of the upper beam 41 and the lower beam 42 toward the inward side.

[0042] A clamping part 5 is slidably disposed between the outer plate 43 and the inner plate 44. The range of motion of the clamping part 5 is limited by the distance between the outer plate 43 and the inner plate 44 to prevent excessive movement.

[0043] More preferably, the mounting component further includes a boom plate 45 disposed on the side of the inner plate 44 away from the outer plate 43, and both the inner plate 44 and the boom plate 45 are provided with connecting parts for connecting the loader boom 2.

[0044] The mounting components also include a tie rod plate 46 disposed on the side of the boom plate 45 away from the inner plate 44, the tie rod plate 46 being used to connect the loader's power tie rod 3.

[0045] The connecting frame 4 has a fixing plate 47 for mounting the power unit in the middle.

[0046] During operation, the boom plate 45 of the connecting frame 4 is connected to the loader boom 2, and the tie rod plate 46 is fixed to the loader's power tie rod 3, thus completing the quick installation of the device.

[0047] The loader is operated to move the tilting device to the position of the blowout preventer 1. The hydraulic cylinder 6 is started to push the two clamping parts 5 on both sides to move in opposite directions. The arc surface of the clamping plate 511 adaptively fits the outer diameter of the blowout preventer 1 to achieve automatic centering and clamping.

[0048] The loader boom 2 works in coordination to rotate the blowout preventer 1. Then, through the lifting and moving functions of the boom 2, the blowout preventer 1 is transferred to the target position.

[0049] Then the hydraulic cylinder 6 is released, the clamping part 5 is reset, and the blowout preventer 1 is disengaged from the device, completing the entire process.
