Lightweight cantilever beam for drilling platforms

Abstract

This lightweight cantilever beam for drilling platforms belongs to the technical field of self-elevating drilling platforms. It includes a cantilever beam body with a first ventilation structure fixedly installed on its top. Multiple reinforcing ribs are provided on the outer surface of the cantilever beam body. The first ventilation structure includes a second top cover, and a second ventilation structure is provided on the top of the second top cover. Driven by a motor, its output shaft drives a dial wheel to rotate via a reducer. Since the dial wheel meshes with the outer surface of the screw, its rotation causes the screw to move horizontally to one side. This allows a moving block to move within a sliding rail. Because the sliding groove is slidably connected to the connecting rod, the movement of the moving block causes a side block to slide within the sliding groove. This causes the side block to fold a folding plate, opening the second top cover and increasing the contact area between the cantilever beam body and the external air. This avoids damage to the cantilever beam body caused by excessive humidity, achieving good ventilation and preventing fire risks.

Description

Technical Field

[0001] This invention relates to the field of self-elevating drilling platform technology, specifically to a lightweight cantilever beam for drilling platforms. Background Technology

[0002] The cantilever beam is the carrier of the drilling function of the jack-up drilling platform. The drilling and well control related equipment and systems are arranged inside it. During drilling operations, the cantilever beam needs to extend outside the ship, and the extent of its extension determines the size of the drilling operation area.

[0003] Traditional cantilever beams generally adopt a closed box-type structure, which has certain shortcomings in actual use: due to their closed structure, the humidity inside the cantilever beam may increase under poor ventilation. Excessive humidity will cause the material to expand and contract, thus affecting the dimensional stability and structural performance of the cantilever beam, and also poses a risk of fire. Based on the shortcomings of existing technology, this invention designs a lightweight cantilever beam for drilling platforms. Summary of the Invention

The first ventilation structure includes a second top cover, and a second ventilation structure is provided on the top of the second top cover. Multiple folding plates are hingedly installed inside the second top cover, and side blocks are fixedly installed on one side of the top of the multiple folding plates. A connecting rod is fixedly installed on one side of the multiple side blocks. The second ventilation structure includes a sliding rail, two triangular support plates, a support platform, and a reducer. A moving block is slidably installed inside the sliding rail, and multiple sliding grooves are opened inside the moving block. The multiple sliding grooves are slidably connected to the connecting rod. A screw is fixedly installed on one side of the outer surface of the moving block. A dial wheel is rotatably installed inside the two triangular support plates, and the dial wheel meshes with the outer surface of the screw. A motor is fixedly installed on the top of the support platform, and the output shaft of the motor is rotatably connected to the dial wheel after passing through the reducer.

[0006] As a preferred embodiment of the present invention, a first top cover is fixedly installed on the top of the cantilever beam body, and the first top cover is fixedly connected to two triangular support plates, a support platform, and a reducer.

[0007] As a preferred embodiment of the present invention, a partition plate is fixedly installed inside the cantilever beam body, and a deck is provided on the right side of the partition plate.

[0008] As a preferred embodiment of the present invention, the cantilever beam body is provided with a water spray structure, which includes two water pumps, and water pumping pipes are fixedly installed on both sides of the top of the two water pumps.

[0009] As a preferred embodiment of the present invention, three water pipes are fixedly installed on one side of the two water pumps, and six water pipes penetrate the interior of the cantilever beam body. Multiple nozzles are fixedly installed on one side of the outer surface of the six water pipes.

[0010] As a preferred embodiment of the present invention, a door structure is fixedly installed on one side of the outer surface of the cantilever beam body, and the door structure includes two sliding strips and a mounting plate.

[0011] As a preferred embodiment of the present invention, a door panel is slidably installed inside the two sliding groove strips, and a fixing plate is fixedly installed inside the door panel.

[0012] As a preferred embodiment of the present invention, two fans are fixedly installed inside the fixed plate, and the two fans are connected to the interior of the cantilever beam body.

[0013] As a preferred embodiment of the present invention, the mounting plate is fixedly connected to the first top cover, and two movable cylinders are fixedly installed on one side of the outer surface of the mounting plate.

[0014] As a preferred embodiment of the present invention, a fixing block is fixedly installed at one end of the telescopic rod of the two movable cylinders, and the two fixing blocks are fixedly connected to the door panel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The lightweight cantilever beam of this drilling platform, through a first ventilation structure and a second ventilation structure, allows the cantilever beam body to be ventilated when necessary. Driven by a motor, its output shaft, via a reducer, drives a dial wheel to rotate. Since the dial wheel meshes with the outer surface of the screw, its rotation causes the screw to move horizontally to one side. This allows the moving block to move within the sliding rail. Because the sliding groove is slidably connected to the connecting rod, the moving block's movement causes a side block to slide within the sliding groove. This allows the side block to fold the folding plate, opening the second top cover and increasing the contact area between the cantilever beam body and the external air. This prevents excessive humidity from damaging the cantilever beam body, achieving good ventilation and avoiding the risk of fire.

[0017] 2. The lightweight cantilever beam of this drilling platform features a water spray structure. In the event of a fire, two water pipes are connected to a water tank, and two water pumps drive water through the water pipes and spray it from the nozzles, thereby extinguishing the fire inside the cantilever beam and improving the safety of the cantilever beam's interior.

[0018] 3. The drilling platform features a lightweight cantilever beam. Through the cantilever beam body, partition plate, and deck, the mud treatment system is modularly integrated and arranged in the open area of ​​the deck. Inside, apart from drilling-related equipment arranged in the space on the left side of the partition plate, only control units and electronic equipment are arranged, which reduces the equipment load and lowers the requirements for the structure and slip system.

The first ventilation structure 4 includes a second top cover 41, and a second ventilation structure 5 is provided on the top of the second top cover 41. Multiple folding plates 42 are hingedly installed inside the second top cover 41, and side blocks 43 are fixedly installed on one side of the top of the multiple folding plates 42. Connecting rods 44 are fixedly installed on one side of the multiple side blocks 43. The second ventilation structure 5 includes a sliding rail 51 and two... The system includes a triangular support plate 55, a support platform 57, a reducer 59, and a sliding block 52 slidably installed inside the sliding rail 51. The sliding block 52 has multiple sliding grooves 54 inside, which are slidably connected to the connecting rod 44. A screw 53 is fixedly installed on one side of the outer surface of the sliding block 52. A dial wheel 56 is rotatably installed inside the two triangular support plates 55. The dial wheel 56 meshes with the outer surface of the screw 53. A motor 58 is fixedly installed on the top of the support platform 57. The output shaft of the motor 58 is rotatably connected to the dial wheel 56 after passing through the reducer 59.

[0030] Please see Figure 1-2 A first top cover 3 is fixedly installed on the top of the cantilever beam body 1. The first top cover 3 is fixedly connected to two triangular support plates 55, a support platform 57, and a reducer 59. A partition plate 7 is fixedly installed inside the cantilever beam body 1, and a deck 8 is provided on the right side of the partition plate 7.

[0031] By modularly integrating the mud treatment system and arranging it in the open area of ​​deck 8, the interior of which, apart from drilling-related equipment arranged in the space to the left of partition 7, only control units and electronic equipment are arranged, reducing the equipment load and lowering the requirements for the structure and slip system.

[0032] Please see Figure 2-3 The cantilever beam body 1 is equipped with a water spray structure 6, which includes two water pumps 61. Water pumping pipes 64 are fixedly installed on both sides of the top of the two water pumps 61. Three water pipes 62 are fixedly installed on one side of the two water pumps 61. The six water pipes 62 penetrate the interior of the cantilever beam body 1, and multiple nozzles 63 are fixedly installed on one side of the outer surface of the six water pipes 62.

[0033] By connecting two water pipes 64 to a water tank and driving two water pumps 61, water is sprayed out from the nozzle 63 after passing through the water pipe 62, thereby extinguishing the fire inside the cantilever beam body 1 and improving the safety inside the cantilever beam body 1.

[0034] Please see Figure 1-3A door structure 9 is fixedly installed on one side of the outer surface of the cantilever beam body 1. The door structure 9 includes two sliding strips 91 and a mounting plate 95. Door panels 92 are slidably installed inside the two sliding strips 91, and a fixing plate 93 is fixedly installed inside the door panels 92. Two fans 94 are fixedly installed inside the fixing plate 93, and the two fans 94 are connected to the interior of the cantilever beam body 1. The mounting plate 95 is fixedly connected to the first top cover 3, and two moving cylinders 96 are fixedly installed on one side of the outer surface of the mounting plate 95. A fixing block 97 is fixedly installed at one end of the telescopic rod of the two moving cylinders 96, and the two fixing blocks 97 are fixedly connected to the door panels 92.

[0035] Driven by two moving cylinders 96, the two telescopic rods can be driven by the fixed block 97 to slide the door panel 92 upward inside the slide rail 91, thereby exposing the cantilever beam body 1, which is convenient for construction personnel to pass through quickly. At the same time, the ventilation effect inside the cantilever beam body 1 is improved by the fan 94.

[0036] Working principle: When the lightweight cantilever beam of the drilling platform is used, the mud treatment system is first modularly integrated and arranged in the open area of ​​deck 8. Inside, apart from drilling-related equipment located in the space to the left of the partition 7, only control units and electronic equipment are housed, reducing equipment load and lowering requirements on the structure and slip system. In case of fire, by connecting two water pipes 64 to a water tank, and driven by two water pumps 61, water is sprayed through the water pipe 62 and then from the nozzle 63, thereby extinguishing fire sources inside the cantilever beam body 1, improving the safety inside the cantilever beam body 1. Finally, When ventilation is required for the cantilever beam body 1, the output shaft of the motor 58 drives the dial wheel 56 to rotate via the reducer 59. Since the dial wheel 56 meshes with the outer surface of the screw 53, the rotation of the dial wheel 56 can drive the screw 53 to move horizontally to one side, thereby allowing the moving block 52 to move inside the sliding rail 51. Since the sliding groove 54 is slidably connected to the connecting rod 44, the movement of the moving block 52 can drive the side block 43 to slide in the sliding groove 54, thereby allowing the side block 43 to drive the folding plate 42 to fold, thus opening the second top cover 41 and increasing the contact area between the cantilever beam body 1 and the external air.
