Ultra-high load offshore drilling cable cage Technical Field

[0001] This utility model relates to the field of drilling cage technology, and in particular to ultra-high load near-shore drilling cable cage. Background Technology

[0002] The ultra-high load capacity offshore drilling cable cage is a type of equipment used on offshore oil drilling platforms. This cage is mainly used to transport personnel and materials on offshore oil drilling platforms, facilitating the transfer of personnel or materials to drilling platforms or cargo ships.

[0003] When using existing ultra-high load offshore drilling cable cages, the cage includes a top plate, support rods, and a bottom plate. The bottom plate is used to place personnel and materials, and the top plate facilitates connection to the hoisting rope. The support rods facilitate support for the bottom plate. Personnel or materials from cargo ships or drilling platforms are placed into the cage, and the cage is lifted by a crane. The personnel or materials in the cage are then transported to the drilling platform or cargo ship by the crane.

[0004] However, in implementing the relevant technology, the following problems were found with the existing ultra-high load offshore drilling cable cages: when personnel or materials are not properly placed in the cage, the center of gravity of the cage is easily unstable, which can cause the cage to tilt and easily cause personnel or materials to fall out of the cage, thereby reducing the safety of the equipment. In view of this, an ultra-high load offshore drilling cable cage is provided to overcome the above defects. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-high load near-shore drilling cable cage.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an ultra-high load near-shore drilling rope cage, comprising a base plate, a support rod fixedly mounted on the top of the base plate, a top plate fixedly mounted on the top of the support rod, a plurality of lifting lugs fixedly mounted on the top of the top plate, a shielding net fixedly mounted between the top plate and the base plate, a positioning ring fixedly mounted on the side of the base plate, a positioning groove opened on the top of the positioning ring, a plurality of counterweights slidably connected inside the positioning groove, a limiting box fixedly mounted on the top of each of the counterweights, a connecting block slidably connected inside each of the limiting boxes, a limiting shaft fixedly mounted inside each of the connecting blocks, a limiting spring mounted on the side of each of the limiting shafts, a limiting spring fixedly connected to the top of each of the limiting springs, and a limiting spring fixedly connected to the top of the inside of each of the limiting boxes; and a plurality of handrails mounted on the side of the support rod.

[0007] As a further description of the above technical solution: the positioning ring has a plurality of limiting holes inside, and the sides of the plurality of limiting shafts respectively fit into the interior of the corresponding plurality of limiting holes, so that the positioning ring can improve the stability of the counterweight when it moves.

[0008] As a further description of the above technical solution: each of the counterweights has a sliding hole inside, and the interior of each sliding hole is in contact with the side of a number of limiting shafts, so that the counterweights can balance the center of gravity of the cage.

[0009] As a further description of the above technical solution: several slide rails are fixedly provided on the side of the support rod, and each of the slide rails has a groove inside, which facilitates the improvement of the stability of the slider when it moves.

[0010] As a further description of the above technical solution: each of the several sliding grooves has a slider slidably connected inside, each of the several sliders has two movable grooves inside, and the bottom ends of the several sliders are respectively fixedly connected to the sides of several handrails, so that the sliders can easily drive the handrails to move up and down.

[0011] As a further description of the above technical solution: each of the several movable slots is slidably connected to a fixed shaft, and each of the several fixed shafts is fixedly provided with a pressure plate on its side, the pressure plate facilitating the movement of the fixed shaft.

[0012] As a further description of the above technical solution: a fixing spring is fixedly provided at one end of each of the fixing shafts, and one side of each of the fixing springs is fixedly connected to the interior of a plurality of sliders, so that the fixing springs can press the fixing shafts.

[0013] As a further description of the above technical solution: several fixing holes are opened inside the sliding rails, and the sides of the fixing shafts respectively fit into the interior of the corresponding fixing holes, so that the fixing shafts can limit the slider.

[0014] This utility model has the following beneficial effects:

[0015] This utility model designs an ultra-high load near-shore drilling cable cage. Through its design, when the cage tilts, the corresponding limiting shaft on the counterweight block in the tilting direction moves upward, causing the limiting shaft to disengage from the positioning ring. At this time, the counterweight block moves in the opposite direction of the cage's tilt, making the opposite direction of the cage's tilt heavier, which facilitates the adjustment of the cage's center of gravity. When the counterweight block moves to the designated position, the limiting shaft is released, and the limiting spring pushes the connecting block and the limiting shaft downward, causing the limiting shaft to enter the corresponding limiting hole in the positioning ring, thereby limiting and fixing the position of the counterweight block. This allows the device to quickly adjust the position of the counterweight block, facilitates the adjustment of the cage's center of gravity, maintains the cage's balance during hoisting, improves the stability of the cage during movement, and enhances the safety of the device during use.

[0016] This utility model designs an ultra-high load near-shore drilling rope cage. Through its design and coordination, the handrail strap facilitates easy gripping by personnel. By pressing two pressure plates within the same slider, the fixed shaft disengages from the fixed hole. At this point, moving the slider up and down causes the handrail strap to move up and down, making the height of the handrail strap easy to adjust. Once the height of the handrail strap is adjusted, releasing the pressure plates causes the two fixed seats within the same slider to move away from each other via a fixed spring, allowing the fixed shaft to enter the corresponding fixed hole in the slide rail. This limits the position of the slider and the handrail strap, enabling the device to quickly adjust the height of the handrail strap. This makes the handrail strap suitable for personnel of different heights, improving the stability when gripping the handrail strap, thereby enhancing the comfort and safety of the device during use.

[0023] Referring to Figures 1-4, the ultra-high load near-shore drilling cable cage provided by this utility model includes a base plate 1, a support rod 2 fixedly mounted on the top of the base plate 1, a top plate 3 fixedly mounted on the top of the support rod 2, and several lifting lugs 4 fixedly mounted on the top of the top plate 3. The lifting lugs 4 facilitate the connection of the lifting rope to the top plate 3. A shielding net 5 is fixedly mounted between the top plate 3 and the base plate 1. A positioning ring 6 is fixedly mounted on the side of the base plate 1. A positioning groove is opened at the top of the positioning ring 6. Several counterweights 7 are slidably connected inside the positioning groove. Each counterweight 7 has a limiting box 8 fixedly mounted on its top. Box 8 facilitates the stability of the connecting block 9 during movement. Connecting blocks 9 are slidably connected inside several limiting boxes 8. Limiting shafts 10 are fixedly installed inside several connecting blocks 9. Limiting shafts 10 facilitate the limiting of counterweight 7. Limiting springs 11 are provided on the sides of several limiting shafts 10. Limiting springs 11 facilitate the compression of connecting blocks 9. The bottom ends of several limiting springs 11 are fixedly connected to the top ends of several connecting blocks 9 respectively. The top ends of several limiting springs 11 are fixedly connected to the top ends inside several limiting boxes 8 respectively. Several handrails 12 are provided on the sides of the support rod 2.

[0024] As a further implementation of the above technical solution: the positioning ring 6 has several limiting holes inside, and the sides of several limiting shafts 10 respectively fit into the interior of the corresponding several limiting holes. The positioning ring 6 facilitates the improvement of the stability of the counterweight 7 when it moves.

[0025] As a further implementation of the above technical solution: each of the counterweights 7 has a sliding hole inside, and the inside of the sliding hole is respectively in contact with the side of the limiting shaft 10, so that the counterweights 7 can balance the center of gravity of the cage.

[0026] In practice: the hoisting rope is connected to the top plate 3 via the lifting lug 4. When personnel or goods need to be transported, they are placed on the bottom plate 1. The protective net 5 prevents personnel or goods from slipping out of the hoist cage. The crane moves the hoisting rope and the hoist cage, thereby moving the personnel or goods to the drilling platform or cargo ship. If the personnel or goods are improperly positioned, causing the hoist cage to tilt, the corresponding limit shaft 10 on the counterweight 7 in the tilting direction is moved upward, causing the limit shaft 10 to disengage from the positioning ring 6. At this time, the counterweight 7 is moved in the opposite direction of the hoist cage's tilt, allowing the hoist to move. The weight increases in the opposite direction of the cage's tilt, facilitating the adjustment of the cage's center of gravity and maintaining balance during hoisting. Once the counterweight 7 is moved to the designated position, the limiting shaft 10 is released, and the limiting spring 11 pushes the connecting block 9 and the limiting shaft 10 downwards, causing the limiting shaft 10 to enter the corresponding limiting hole in the positioning ring 6. This limits the counterweight 7, fixing its position. This allows for quick adjustment of the counterweight 7's position, facilitating the adjustment of the cage's center of gravity and maintaining balance during hoisting. This improves the stability of the cage during movement and enhances the safety of the device during use.

[0027] As a further implementation of the above technical solution: a number of slide rails 13 are fixedly provided on the side of the support rod 2, and each of the slide rails 13 has a groove inside, which facilitates the improvement of the stability of the slider 14 when it moves.

[0028] As a further implementation of the above technical solution: a number of sliding grooves are slidably connected to the inside of each sliding groove, and each of the sliding grooves has two movable grooves inside. The bottom ends of the sliding grooves are fixedly connected to the sides of the handrails 12 respectively, so that the sliding grooves can easily drive the handrails 12 to move up and down.

[0029] As a further implementation of the above technical solution: a number of movable slots are slidably connected with fixed shafts 15, and pressure plates 16 are fixedly provided on the sides of the fixed shafts 15, which facilitates the movement of the fixed shafts 15.

[0030] As a further implementation of the above technical solution: a fixing spring 17 is fixedly provided at one end of a plurality of fixing shafts 15, and one side of the plurality of fixing springs 17 is fixedly connected to the interior of a plurality of sliders 14 respectively, so that the fixing springs 17 can press the fixing shafts 15.

[0031] As a further implementation of the above technical solution: several fixing holes are opened inside several slide rails 13, and the sides of several fixing shafts 15 respectively fit into the interior of the corresponding fixing holes, so that the fixing shafts 15 can limit the slider 14.

[0032] In practical implementation: After personnel enter the cage, the handrail 12 facilitates their grip, improving stability as the cage moves. When personnel are too tall or too short to grip the handrail 12 easily, pressing the two pressure plates 16 within the same slider 14 moves the two fixed shafts 15 closer together, disengaging them from their fixing holes. Moving the slider 14 up and down then moves the handrail 12 up and down, allowing for easy height adjustment. Once the height is adjusted, releasing the pressure plates 16 allows the fixing spring 17 to push the two fixed seats within the same slider 14 away from each other, causing the fixed shafts 15 to enter their corresponding fixing holes in the slide rail 13. This limits the slider 14 and the handrail 12, enabling quick and easy height adjustment. This makes the handrail 12 suitable for personnel of different heights, improving stability and enhancing user comfort and safety.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
