Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-9The present invention provides a technical solution: a vertical lifting device for a blowout preventer with a rotation alignment mechanism, wherein a lateral driving device 1 can drive a mounting plate 2 to move laterally, and the lateral driving device 1 is installed above a vertical driving device 3.

[0038] Specifically, the transverse driving device 1 includes a transverse mounting block 101, and a through slot 102 is provided on the transverse mounting block 101. The through slot 102 facilitates the subsequent connection of the driving block 1031 with the mounting plate 2. A screw mechanism 103 is rotatably arranged inside the through slot 102, and the screw mechanism 103 is connected to the driving block 1031 slidingly arranged inside the through slot 102. The driving block 1031 is fixedly connected to the rear side of the mounting plate 2, and the driving block 1031 can drive the mounting plate 2 to move synchronously.

[0039] Specifically, one end of the screw mechanism 103 is connected to a second driving motor 104 disposed outside the transverse mounting block 101 .

[0040] When it is necessary to drive the mounting plate 2 and the blowout preventer 7 limited on the outer side of the mounting plate 2 to move horizontally, the second drive motor 104 is turned on, and the screw mechanism 103 rotates under the action of the second drive motor 104, thereby driving the drive block 1031 to move inside the through groove 102, and the mounting plate 2 is driven to move synchronously through the drive block 1031.

[0041] Specifically, an arc guide rail 4 is installed on the outer side of the mounting plate 2, and an electric slider 401 used therewith is arranged inside the arc guide rail 4, and the electric slider 401 is connected to a disc 501 rotatably arranged on the outer side of the mounting plate 2 through a fixing bar 5, and the electric slider 401 moves inside the arc guide rail 4, thereby driving the fixing bar 5 to rotate with the disc 501 as the center point, and L-shaped mounting frames 6 are symmetrically arranged on both sides of the fixing bar 5, and a moving plate 601 is slidably arranged inside the L-shaped mounting frame 6, and the outer side of the moving plate 601 is connected to a mounting frame 6021 fixedly arranged on the outer side of the L-shaped mounting frame 6 through a hydraulic rod 602, and the inner side of the moving plate 601 is connected to an arc clamping plate 604 through two sets of symmetrically arranged connecting columns 603, and the arc clamping plates 604 on both sides can clamp the anti-blowout pipe 7, and the hydraulic rod 60 is adjusted. 2, so that the arc clamping plate 604 is driven to move by the movable plate 601 and the connecting column 603 to realize the clamping of the blowout preventer 7. A positioning groove 605 is installed on the inner side of the movable plate 601 and between the two groups of connecting columns 603, and a driving roller 606 used in conjunction with the blowout preventer 7 is rotatably arranged on the inner side of the positioning groove 605. One end of the driving roller 606 is connected to a first driving motor 607 arranged on the outer side of the positioning groove 605. The first driving motor 607 can drive the driving roller 606 to rotate, so that the blowout preventer 7 is transported through the cooperation of the two groups of driving rollers 606. An angle ruler 10 is arranged on the outer side of the mounting plate 2 and at the outer end of the arc guide rail 4. The angle ruler 10 is arranged to facilitate timely understanding of the rotation angle of the blowout preventer 7. The angle ruler 10 is arranged at the outer end of the arc guide rail 4 to avoid the fixed bar 5 from blocking the angle ruler 10.

[0042] To further explain, the L-shaped mounting frame 6 is provided with a moving groove for use with the hydraulic rod 602 .

[0043] When the lubricant pipe 7 needs to be adjusted in its inclination angle to be installed at an angle, the lubricant pipe 7 is placed inside the arc-shaped clamping plate 604 and the driving roller 606, and the two sets of hydraulic rods 602 are started. Under the action of the two sets of hydraulic rods 602, the two sets of moving plates 601 are continuously approached, thereby driving the arc-shaped clamping plates 604 and the driving rollers 606 arranged on both sides to continuously approach through the connecting column 603 and the positioning groove 605, and the lubricant pipe 7 is clamped. The position of the lubricant preventer 7 is limited to a certain extent under the action of the action. After the limitation is completed, the electric slider 401 is turned on to drive the fixing bar 5 to rotate around the disk 501, and the lubricant preventer 7 can be driven to rotate synchronously through the fixing bar 5. After rotating to the docking angle, the first driving motor 607 is turned on, and the first driving motor 607 drives the driving roller 606 to rotate, thereby driving the lubricant preventer 7 to move through the cooperation of the two groups of driving rollers 606, so that one end of the lubricant preventer 7 is inserted into the inside of the connector set at the wellhead and connected with it.

[0044] Specifically, the vertical drive device 3 includes two symmetrically arranged groups of fixed boxes 301, and two groups of limit slide bars 302 are arranged inside the fixed boxes 301. The limit slide bars 302 are slidably connected with the limit slide blocks 303, and the limit slide blocks 303 are installed on the outside of the lifting plate 304. By setting the limit slide bars 302, the moving direction of the lifting plate 304 can be limited, so that the movement of the lifting plate 304 is more stable. A rack plate 305 is arranged on the inside of the lifting plate 304, and the rack plate 305 is meshed with a gear 306. The two groups of gears 306 are meshed, and one group of gears 306 is connected to the synchronous driving mechanism 8 arranged on the outside of the fixed box 301. The synchronous driving mechanism 8 can drive the gears 306 arranged inside the two groups of fixed boxes 301 to rotate, so that the lifting plates 304 are synchronously displaced. The tops of the two groups of lifting plates 304 pass through the outside of the fixed box 301 and are connected by the top plate 307, and the tops of the two groups of top plates 307 are connected by the horizontal mounting block 101.

[0045] Specifically, the synchronous drive mechanism 8 includes an installation box 801, and a rotating rod 802 is rotatably arranged inside the installation box 801, two groups of first bevel gears 803 are installed on the outside of the rotating rod 802, and the first bevel gears 803 are meshed with the second bevel gears 804, and the second bevel gear 804 is installed on the outside of a driving rod 805, and the driving rod 805 can drive a group of gears 306 arranged inside the fixed box 301 to rotate, and one end of the rotating rod 802 is connected to a fourth driving motor 806 arranged on the outside of the installation box 801.

[0046] When it is necessary to drive the transverse drive device 1, the mounting plate 2 and the blowout preventer 7 fixed on the outside of the mounting plate 2 to move vertically, the fourth drive motor 806 is turned on. Under the action of the fourth drive motor 806, the rotating rod 802 drives the first bevel gear 803 to rotate. The first bevel gear 803 is meshed with the second bevel gear 804, so the second bevel gear 804 and the driving rod 805 can be driven to rotate. The driving rod 805 drives a group of gears 306 to rotate. Since the gears 306 are meshed with each other, the two groups of gears 306 can be driven to rotate. Under the action of the rotation of the gears 306, the rack plate 305 moves, thereby driving the lifting plate 304 to synchronously displace, so that the height of the top plate 307 changes, thereby driving the transverse drive device 1, the mounting plate 2 and the blowout preventer 7 fixed on the outside of the mounting plate 2 to move vertically.

[0047] Specifically, a base 9 is installed at the bottom of the fixed box 301, and an open groove 901 is opened at the bottom of the base 9. A lifting pulley mechanism 902 is arranged inside the open groove 901. By setting the lifting pulley mechanism 902, the pulley 9026 in the lifting pulley mechanism 902 can be moved to the outside of the open groove 901 when the device is moved, and the pulley 9026 is used to push the device to move. After moving to the specified position, the pulley 9026 is completely moved to the inside of the open groove 901, so that the bottom of the base 9 is directly in contact with the ground, which improves the stability when placed. The lifting pulley mechanism 902 includes a rotating rod 9021, and one end of the rotating rod 9021 is connected to a third driving motor 9022 arranged on the outside of the opening slot 901, two sets of second gears 9023 are arranged on the outside of the rotating rod 9021, and the second gear 9023 is meshed with a rack 9024, and the bottom of the rack 9024 is connected through an adjusting plate 9025, and a pulley 9026 is installed under the adjusting plate 9025, and a limiting rod 9027 is symmetrically arranged inside the opening slot 901, and the limiting rod 9027 is slidably connected to the adjusting plate 9025.

[0048] To further explain, an anti-self-rotation mechanism is installed at the output end of the third drive motor 9022 to prevent the output end of the third drive motor 9022 from self-rotating.

[0049] When the device needs to be moved, the third drive motor 9022 is turned on. Under the action of the third drive motor 9022, the second gear 9023 rotates to drive the rack 9024 to move. Under the action of the movement of the rack 9024, the adjustment plate 9025 and the pulley 9026 move. When the pulley 9026 moves to the outside of the opening slot 901, the device can be pushed to move by the pulley 9026.
