Description

Technical Field

[0001] This utility model relates to the field of blowout preventer installation technology, specifically a blowout preventer for drilling platforms. Background Technology

[0002] Blowout preventers (BOPs) are critical safety devices used in oil and gas drilling operations to control wellbore pressure. Their main function is to prevent formation fluids (such as oil, gas, and water) from being ejected from the wellhead due to uncontrolled pressure during drilling (i.e., a blowout accident). By mechanically sealing the wellbore, they can quickly disconnect the connection between the wellhead and the drill string in an emergency, ensuring the safety of personnel, equipment, and the environment.

[0003] Because of their own weight, blowout preventers cannot be installed manually. Traditionally, blowout preventers are first hoisted to the designated location by a crane. However, in order to align the flange mounting holes at the bottom of the blowout preventer with the installation position, workers are often required to assist in positioning during hoisting. If workers make mistakes, it may threaten their personal safety and reduce the safety and convenience of equipment installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a blowout preventer for drilling platforms. It solves the problem that traditional blowout preventers are typically hoisted to a designated location by a crane before installation. However, to ensure that the flange mounting holes at the bottom of the blowout preventer align with the installation position, workers are often required to assist in positioning during hoisting. If workers make operational errors, it may threaten their personal safety, thus reducing the safety and convenience of equipment installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blowout preventer for drilling platforms, comprising an adjustment platform, a push handle fixedly connected to one side of the adjustment platform near the top, a first sliding groove formed at the center of the top of the adjustment platform, a positioning groove formed on the other side of the adjustment platform, a lead screw rotatably connected to the inner wall of one side of the first sliding groove, a slider threadedly connected to the outer surface of the lead screw, a first motor fixedly installed on the bottom of one side of the adjustment platform near the push handle, the output end of the first motor being fixedly welded to one end of the lead screw, and the blowout preventer body placed on the top of the adjustment platform near the slider.

[0006] In a preferred embodiment, an inner support rod is fixedly installed at the bottom of the adjustment platform near each of the four corners, and a transmission frame is fixedly installed at the bottom of each of the four inner support rods.

[0007] In a preferred embodiment, an outer support sleeve is slidably fitted onto the outer surface of each of the four inner support rods, a second sliding groove is provided through both sides of each of the four outer support sleeves, and a caster wheel is fixedly installed at the bottom of each of the four outer support sleeves.

[0008] In a preferred embodiment, a fixed platform is fixedly connected between the outer surfaces of the opposite sides of each pair of outer support sleeves, and two rotating rods are rotatably arranged near the top between the front and rear sides of the fixed platform, with worm gears fixedly sleeved on the outer surfaces of the two rotating rods.

[0009] In a preferred embodiment, both ends of the two rotating rods are fixedly connected to a transmission arm, and one end of each of the four transmission arms is fixedly connected to a transmission frame.

[0010] In a preferred embodiment, a second motor is fixedly installed at the center of the inner bottom surface of the fixed platform, and a worm gear is fixedly welded to the output end of the second motor.

[0011] In a preferred embodiment, the transmission frame is slidably sleeved with the transmission bracket, and the worm gear is meshed with the worm wheel.

[0012] Beneficial effects

[0013] This utility model provides a blowout preventer for drilling platforms. Compared with the prior art, it has the following advantages:

[0014] In this utility model, when the blowout preventer body is placed on the adjustment platform by the hoisting equipment, the adjustment platform and the blowout preventer body can be moved closer to the installation platform by pushing the push handle. The positioning slot can be used to dock and position with the installation platform. By starting the second motor, the inner support rod can be driven to slide upward inside the outer support sleeve rod under the transmission structure, so that the adjustment platform is adjusted upward. The reverse is also the same.

[0015] When the adjustment platform is adjusted to be level with the installation platform, the first motor is started to drive the lead screw to rotate, thereby causing the slider to slide to one side inside the first slide groove. With the push of the slider on the blowout preventer body, the blowout preventer body can be smoothly connected to the installation platform with the hoisting equipment to complete the installation. This avoids the need for personnel to directly contact the blowout preventer body for auxiliary positioning, thus improving the safety and convenience of the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-3 A blowout preventer for drilling platforms includes an adjustment platform 1. A push handle 2 is fixedly connected to one side of the adjustment platform 1 near the top. A first groove 3 is provided at the center of the top of the adjustment platform 1. A positioning groove 4 is provided on the other side of the adjustment platform 1. A lead screw 5 is rotatably connected to the inner wall of one side of the first groove 3. A slider 6 is threadedly connected to the outer surface of the lead screw 5. A first motor 7 is fixedly installed on the bottom of one side of the adjustment platform 1 near the push handle 2. The output end of the first motor 7 is fixedly welded to one end of the lead screw 5. The blowout preventer body 8 is placed on the top side of the adjustment platform 1 near the slider 6.

[0024] In this embodiment, when the blowout preventer body 8 is placed on the adjustment platform 1 by the hoisting equipment, the adjustment platform 1 and the blowout preventer body 8 can be moved closer to the installation platform by pushing the push handle 2, with the universal wheels 13. The positioning groove 4 can connect with the installation platform. When the adjustment platform 1 is adjusted to be flush with the installation platform, the first motor 7 is started to drive the lead screw 5 to rotate through the threaded connection between the lead screw 5 and the slider 6. This causes the slider 6 to slide stably to one side inside the first slide groove 3. With the push of the slider 6 on the blowout preventer body 8, the blowout preventer body 8 can be smoothly connected to the installation platform with the hoisting equipment, thus completing the installation.

[0025] Example 2:

[0026] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: an inner support rod 9 is fixedly installed at the bottom of the adjustment platform 1 near the four corners, a transmission frame 10 is fixedly installed at the bottom of the four inner support rods 9, an outer support sleeve rod 11 is slidably sleeved on the outer surface of the four inner support rods 9, a second sliding groove 12 is opened through both sides of the four outer support sleeve rods 11, and a universal wheel 13 is fixedly installed at the bottom of the four outer support sleeve rods 11.

[0027] In this embodiment, the inner support rod 9 and the outer support sleeve rod 11 provide stable support for the equipment. The universal wheels 13 provide flexible movement for the equipment. The second slide groove 12 facilitates the sliding of the transmission frame 17 within the second slide groove 12. When the transmission frame 10 is subjected to an upward force from the transmission frame 17, it will drive the inner support rod 9 to slide upward, thereby driving the adjustment table 1 to slide upward for adjustment. The reverse is also true.

[0028] A fixed platform 14 is fixedly connected between the outer surfaces of two opposite sides of the outer support sleeves 11. Two rotating rods 15 are rotatably arranged between the front and rear sides of the fixed platform 14 near the top. A worm gear 18 is fixedly sleeved on the outer surface of each of the two rotating rods 15. A transmission arm 16 is fixedly connected to both ends of each of the two rotating rods 15. A transmission frame 17 is fixedly connected to one end of each of the four transmission arms 16. A second motor 19 is fixedly installed at the center of the bottom surface inside the fixed platform 14. A worm 20 is fixedly welded to the output end of the second motor 19. The transmission frame 17 is slidably sleeved with the transmission frame 10. The worm 20 is meshed with the worm gear 18.

[0029] In this embodiment, when the height of the adjustment platform 1 needs to be adjusted, the second motor 19 is started. The output of the second motor 19 can drive the worm gear 20 to rotate. Through the meshing of the worm gear 20 and the worm wheel 18, when the worm gear 20 rotates, it can simultaneously drive the two worm wheels 18 to rotate. The rotation of the worm wheels 18 can drive the rotating rod 15 to rotate synchronously. The rotation of the rotating rod 15 can drive the transmission arm 16 and the transmission frame 17 to adjust their angles. Through the sliding sleeve of the transmission frame 17 and the transmission frame 10, when the transmission frame 17 is adjusted upwards, it can drive the inner support rod 9 to slide upwards inside the outer support sleeve 11, thereby driving the adjustment platform 1 to adjust upwards.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, when the blowout preventer body 8 is placed on the adjustment platform 1 by the hoisting equipment, the adjustment platform 1 and the blowout preventer body 8 can be moved closer to the installation platform by pushing the push handle 2, with the universal wheels 13. The positioning groove 4 can connect with the installation platform. By starting the second motor 19, the output of the second motor 19 can drive the worm 20 to rotate. Through the meshing of the worm 20 and the worm wheel 18, when the worm 20 rotates, it can drive the two worm wheels 18 to rotate at the same time. The rotation of the worm wheel 18 can drive the rotating rod 15 to rotate synchronously. The rotation of the rotating rod 15 can drive the transmission arm 16 and the transmission frame 17 to adjust the angle. Through the sliding sleeve of the transmission frame 17 and the transmission frame 10, when the transmission frame 17 is adjusted upward, it can drive the inner support rod 9 to slide upward inside the outer support sleeve 11, thereby driving the adjustment platform 1 to adjust upward.

[0032] When the adjusting platform 1 is adjusted to be flush with the installation platform, the first motor 7 is started to drive the lead screw 5 to rotate through the threaded connection between the lead screw 5 and the slider 6. This causes the slider 6 to slide stably to one side inside the first slide groove 3. With the push of the slider 6 on the blowout preventer body 8, the blowout preventer body 8 can be smoothly connected to the installation platform with the hoisting equipment to complete the installation. This avoids the need for personnel to directly contact the blowout preventer body 8 for auxiliary positioning, thus improving the safety and convenience of the equipment.
