Description

Technical Field

[0001] The invention relates to the technical field of marine oil testing, and in particular to an aerial work platform for marine oil testing. Background Art

[0002] With the continuous advancement of offshore oil production technology, offshore oil and gas field development has become an important part of global energy supply. In the process of offshore oil exploration and production, oil testing is one of the key steps in evaluating the potential of newly discovered oil fields.

[0003] In order to conduct effective oil testing operations, it is usually necessary to build a simple platform. After the oil testing operation is completed, the temporary operating platform must be removed from the wellhead under good weather conditions; The above-mentioned operation method requires repeated dismantling and reconstruction of the operation platform. This operation method can only be carried out under good weather conditions. When the weather and sea conditions are bad, the hoisting cage and the wellhead watertight pipe suspended by the crane will shake greatly, and construction cannot be carried out, which seriously delays production. Since manual pushing and alignment are required, the temporary operation platform cannot be made too large. The suitable platform is relatively small, with a length and width of only 2.5m respectively. There is a wellhead in the middle of the table, and there are manifolds and valves around the wellhead. This causes the operators to stand on the table of the temporary wellhead platform to work in a small space and inconvenient operations. In addition, electric welding and gas cutting operations at the wellhead require cumbersome procedures, which will also delay production time and reduce operating efficiency. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an aerial work platform for marine oil testing to solve the problem of marine oil testing.

[0005] Based on the above purpose, the present invention provides an aerial work platform for marine oil testing, including a well repair platform, and also includes: A transverse translation track is fixedly arranged on the top of the well repair platform; Two sets of connecting frames are symmetrically arranged on one side of the well repair platform, the top ends of which are respectively connected to the transverse translation track, and the bottom ends of which are respectively rotatably connected to the folding platform body; The turning hydraulic cylinder is arranged between the connecting frame and the folding platform body, one end of which is rotatably connected to the connecting frame, and the other end is rotatably connected to the folding platform. The turning hydraulic cylinder can fold up and lay flat the folding platform body; The wellhead adjusting pedal is slidably arranged between the two sets of folding platform bodies for inspecting the wellhead.

[0006] Furthermore, the transverse translation track includes an outer beam and an inner beam, the bottom of the outer beam is fixedly connected to the top of the well repair platform, the top of the outer beam is grooved to form a sliding channel, and the inner beam is slidably arranged in the sliding channel; a driving assembly is arranged in the sliding channel to drive the inner beam to slide in the sliding channel; the top of the inner beam is connected to the tops of the two groups of connecting frames.

[0007] Furthermore, the driving assembly includes a translation hydraulic cylinder, which is arranged in the sliding channel, one end of the translation hydraulic cylinder is connected to one end of the sliding channel, and the other end is connected to one end of the inner beam.

[0008] Furthermore, a top seat is provided on a side of the connecting frame close to the well repairing platform.

[0009] Furthermore, a top seat is provided on one side of the connecting frame close to the well repair platform, and the top seat abuts against the side of the well repair platform. A wheel groove is provided on one side of the top seat close to the well repair platform, and a liquid cylinder is provided in the wheel groove, one end of the liquid cylinder is connected to the wheel groove, and the other end is connected to a rubber roller; when the connecting frame translates laterally, the liquid cylinder drives the rubber roller to extend out of the wheel groove and contact the side of the well repair platform, and there is rolling friction between the top seat and the well repair platform, thereby reducing the wear on the side of the well repair platform.

[0010] Furthermore, the wellhead adjustment pedal includes two groups of fixed pedals and a wellhead pedal, the two groups of fixed pedals are fixedly arranged between the two groups of folding platform bodies, and the wellhead pedal is slidably arranged between the two groups of fixed pedals; the adjacent side surfaces of the two groups of folding platform bodies are respectively provided with sliding grooves, and the two sides of the wellhead pedal are respectively slidably matched with the sliding grooves on both sides.

[0011] The beneficial effects of the present invention are as follows: by driving the operation of the flip cylinder, the folding platform body can be smoothly laid flat from the folded state to the working position; there is no need to build a working platform, which simplifies the operation steps, reduces the preparation time, and improves the operation efficiency; by setting the lateral translation track, the folding platform body is adjusted to slide together with the wellhead adjustment pedal in the lateral direction, so as to correct and compensate the lateral position deviation of the well repair platform relative to the wellhead; and by setting the wellhead adjustment pedal, the longitudinal position deviation of the well repair platform relative to the wellhead can be corrected and compensated, ensuring that the well repair platform can be accurately aligned with the wellhead in both the horizontal and vertical directions, thereby improving the operation accuracy and efficiency.
