[0010] A floating assembly is arranged on the top of the casing, and the floating assembly floats along with the casing when the casing is affected by the rising tide and the loosening of the rock formation;

[0011] An alignment component is provided on the top of the floating component, and the alignment component controls the position of the connecting component so that the axis of the sleeve and the axis of the connecting component are on the same vertical line;

[0012] The surface of the alignment component is abutted against a connection component, and the connection component uses an inclined surface to enter and a plane to clamp to assist in connection. The floating component includes a vertical frame, which is composed of two parallel plates, and a floating block is slidably connected to the opposite side of the parallel plates, and a clamping block is fixedly installed on the right side of the floating block, and the side of the clamping block away from the floating block is abutted against a floating plate, and the floating plate is composed of two arc plates, which can be opened left and right, and the top of the arc plate is abutted against an interactive block, and a connecting rod is fixedly installed on the top of the floating block, and a guide block is fixedly installed on the top of the vertical frame, and the connecting rod passes through the guide block, and a connecting block is fixedly installed on the top of the connecting rod, and a connecting tube is fixedly installed on the top of the connecting block.

[0013] The top end of the lifting paddle shifters is fixedly provided with a toothed plate, and the bottom end of the toothed plate is fixedly provided with a toothed plate, and the toothed plate is fixedly provided with a toothed plate at a right end and a left end and a right ...

[0014] Preferably, a slide is fixedly installed on the inner wall of the drill rod, a strip-shaped groove is opened on the slide, a downward pressure separation block is slidably connected to the surface of the slide, a retaining spring is fixedly installed on the side of the downward pressure separation block close to the drill rod, and the end of the retaining spring away from the downward pressure separation block is fixedly connected to the drill rod, and convex strips are fixedly installed on both the front and back sides of the downward pressure separation block.

[0015] Preferably, the top of the casing abuts against the floating plate, the right side of the floating block is fixedly installed on the support frame, the left side of the connecting block is fixedly connected to the frame, the inner wall of the connecting tube is fixedly connected to the horizontal rod, the arc plate is coaxial with the casing, the arc plate is adapted to the connecting assembly, the top of the extrusion block abuts against the drill rod, the surface of the buckle plate abuts against the drill rod, the bottom of the ratchet is rotatably connected to the arc plate, the cross-section of the interactive block is I-shaped, the wedge block is threadedly inserted into the drill rod, and the inclined surface of the downward-pressing separation block abuts against the wedge block.

[0016] 3. Beneficial effects

[0017] (1) A floating assembly is provided on the top of the casing of the present invention. The floating plate rises synchronously with the casing, so that the connecting block and the connecting tube move upward. Therefore, the height of the alignment assembly is adjusted so that the alignment assembly is always located between the casing and the connecting assembly. The above structure solves the problem that the casing is at a high position when the tide is low and cannot be towed and docked.

[0018] (2) An alignment assembly is provided on the right side of the floating assembly of the present invention. The extrusion block contacts and is squeezed by the connection assembly, so that the gusset plate moves toward the center of the arc plate. The gusset plate brings the connection assembly to the center of the arc plate. Since the arc plate and the sleeve are coaxial, the connection assembly is aligned with the axis of the sleeve. The above structure solves the problem that the connection assembly is offset and cannot be automatically aligned with the axis, requiring the operator to apply force, and the high-position operation is dangerous when the tide is low.

[0019] (3) A connecting assembly is provided on the top of the alignment assembly of the present invention. The wedge block separates the downward pressing separation block to both sides. Subsequently, the downward pressing separation block is no longer squeezed and stuck in the position of the connecting block. Since the connecting assembly is operated underwater, it is inevitably subjected to pressure from the outside to the inside. Therefore, the downward pressing separation block will only be squeezed in the direction of the connecting block and will not open, so it will not loosen, thereby solving the problem of too many high-position connection processes.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] Embodiment 1:

[0031] See also Figure 1 and 2 A floating connection device for a drilling rig of a drilling ship comprises a support frame 2, wherein the support frame 2 is fixedly mounted on the top of a deck 1, a sleeve 3 is slidably mounted on the inner wall of the deck 1 and located on the left side of the support frame 2, an interactive block 7 is fixedly connected to the inner wall of the sleeve 3, and a wedge block 8 is fixedly mounted on the top of the interactive block 7.

[0032] A floating assembly 4 is provided on the top of the casing 3. When the casing 3 is affected by the rising tide and the loosening of the rock formation, the floating assembly 4 floats along with the casing 3.

[0033] An alignment component 5 is provided on the top of the floating component 4, and the alignment component 5 controls the position of the connecting component 6 so that the axis of the sleeve 3 and the axis of the connecting component 6 are on the same vertical line;

[0034] The surface of the alignment component 5 is abutted against the connection component 6, and the connection component 6 utilizes the inclined surface to enter and the plane to engage, so as to assist the connection.

[0035] The floating assembly 4 includes a vertical frame 401, which is composed of two parallel plates. A floating block 402 is slidably connected to the opposite side of the parallel plates. The right side of the floating block 402 is fixedly installed with the support frame 2. A clamping block 403 is fixedly installed on the right side of the floating block 402. The side of the clamping block 403 away from the floating block 402 abuts against the floating plate 404. The top of the sleeve 3 abuts against the floating plate 404. The floating plate 404 is composed of two arc plates, which can be opened left and right. The top of the arc plate abuts against the interactive block 7. A connecting rod 405 is fixedly installed on the top of the floating block 402. A guide block 406 is fixedly installed on the top of the vertical frame 401. The connecting rod 405 penetrates the guide block 406. A connecting block 407 is fixedly installed on the top of the connecting rod 405. A connecting tube 408 is fixedly installed on the top of the connecting block 407.

[0036] A floating assembly 4 is provided on the top of the casing 3 of the present invention, and the deck 1 supports the casing 3. When the tide recedes, the height of the casing 3 relative to the deck 1 becomes higher. When the casing 3 pipe mouth is at a high position before drilling, when the height of the operator is not enough, the operator's center of gravity may be unstable or the force control may be wrong when applying force at a high position. The casing 3 drives the floating plate 404 to move when moving. The floating plate 404 uses the clamping block 403 to move the floating block 402. The floating block 402 uses the connecting rod 405 to drive the connecting block 407 to move upward. The connecting block 407 and the connecting tube 408 cooperate to make the alignment assembly 5 rise. When the tide rises, it is the opposite of the above. Regardless of the tide, the height difference between the alignment assembly 5 and the casing 3 is fixed. The floating assembly 4 controls the height of the alignment assembly 5 to prevent the height of the alignment assembly 5 from being lower than the casing 3, which makes it inconvenient for the alignment assembly 5 to be pulled. The height change of the casing 3 relative to the deck 1 due to the ebb and flow of the tide will not affect the pulling.

[0037] Embodiment 2:

[0038] See also Figure 3-5, combined with the basis of embodiment 1, the difference is that the alignment component 5 includes a horizontal rod 501, the inner wall of the connecting tube 408 is fixedly connected to the horizontal rod 501, the right end of the horizontal rod 501 is fixedly installed with an arc plate 502, the arc plate 502 is coaxial with the sleeve 3, the arc plate 502 is adapted to the connecting component 6, the arc plate 502 is provided with two and arranged along a vertical line, the arc plate 502 is rotatably connected with a buckle plate 503 on the opposite side of the arc plate 502, the bottom of the buckle plate 503 is fixedly installed with a ratchet 504, the bottom of the ratchet 504 is rotatably connected to the arc plate 502, the surface of the ratchet 504 is hinged with a latch tooth 505, the side of the latch tooth 505 away from the ratchet 504 is fixedly installed with a telescopic rod 506, and the side of the telescopic rod 506 away from the latch tooth 505 is fixedly installed with A support plate 507 is provided with a return spring 508 fixedly installed on the surface of the support plate 507 and on the same side of the telescopic rod 506. The side of the return spring 508 away from the support plate 507 is fixedly connected to the latch tooth 505. A rotating shaft 515 is fixedly installed at the bottom of the ratchet 504. The bottom of the rotating shaft 515 is provided with teeth. A tooth plate 514 is meshedly connected to the side of the rotating shaft 515 near the center of the arc plate 502. An L frame 512 is fixedly installed at one end of the tooth plate 514. A support block 513 is slidably connected to the surface of the L frame 512. An extrusion block 511 is fixedly installed at the other end of the L frame 512. A compression spring 510 is fixedly installed on the right end of the extrusion block 511. The front and back sides of the extrusion block 511 are slidably connected to a square frame 509. The left side of the connecting block 407 is fixedly connected to the square frame 509.

[0039] The right side of the floating component 4 of the present invention is provided with an alignment component 5. The connecting block 407 and the connecting tube 408 cooperate to drive the alignment component 5 to move upward, and the alignment component 5 is directed toward the connecting component 6. The extrusion block 511 moves upward to contact the drill rod 601. The drill rod 601 squeezes the extrusion block 511. The extrusion block 511 is restricted by the square frame 509 and can only move horizontally. The extrusion block 511 moves along the direction of the square frame 509 to compress the compression spring 510. Then the extrusion block 511 drives the tooth plate 514 to move by using the L frame 512. The support block 513 guides and supports. The tooth plate 514 drives the rotating shaft 515 to rotate, so that the buckle plate 503 rotates. The opening of the buckle plate 503 is large and has an arc, which is convenient for the connecting component 6 to enter the opening of the buckle plate 503. The buckle plate 503 rotates to bring the connecting component 6 to the arc plate 502. The ratchet 504 and the latch tooth 505 cooperate. When the buckle plate 5 When the buckle plate 503 moves toward the center of the circle of the arc plate 502, the ratchet 504 uses the inclined surface to squeeze the locking tooth 505 in the direction of the support plate 507, and the support plate 507 guides it. Then the reset spring 508 assists the locking tooth 505 to reset and engage with the ratchet 504 again. When the buckle plate 503 moves away from the center of the circle of the arc plate 502, the locking tooth 505 clamps the ratchet 504 so that the buckle plate 503 can only move in one direction. The buckle plate 503 and the arc plate 502 form a complete circle to prevent the buckle plate 503 from being squeezed out by the connecting component 6. Since the arc plate 502 is coaxial with the sleeve 3, the connecting component 6 is brought to the axis of the sleeve 3 by the buckle plate 503, so that the connecting component 6 can be docked with the interactive block 7 and the wedge block 8. With the above structure, the connecting component 6 is pulled to the axis of the sleeve 3 by the extrusion force of the connecting component 6, and the automatic alignment facilitates the docking of the connecting component 6 with the wedge block 8.

[0040] Embodiment 3:

[0041] See also Figure 6 and 7 , combined with the basis of Example 2, the difference is that a slideway 602 is fixedly installed on the inner wall of the drill rod 601, a strip groove 603 is opened on the slideway 602, and a downward pressing separation block 604 is slidably connected to the surface of the slideway 602. A retaining spring 605 is fixedly installed on the side of the downward pressing separation block 604 close to the drill rod 601, and the end of the retaining spring 605 away from the downward pressing separation block 604 is fixedly connected to the drill rod 601, and convex strips 606 are fixedly installed on both sides of the downward pressing separation block 604.

[0042] The top of the extrusion block 511 abuts against the drill rod 601, the surface of the pinch plate 503 abuts against the drill rod 601, the cross-section of the interactive block 7 is I-shaped, the wedge block 8 is threadedly inserted into the drill rod 601, and the inclined surface of the downward pressing separation block 604 abuts against the wedge block 8.

[0043] The top of the alignment component 5 of the present invention is provided with a connecting component 6. When the connecting component 6 moves downward, the pressing and separating block 604 contacts the wedge block 8 first, and the wedge block 8 separates the pressing and separating block 604 to both sides. The pressing and separating block 604 compresses the retaining spring 605, and the slideway 602 and the convex strip 606 cooperate to guide to prevent the pressing and separating block 604 from being squeezed and offset. Then, the top surface of the pressing and separating block 604 moves to the horizontal midline of the interactive block 7. Since the cross-sectional area of ​​the interactive block 7 is an I-shaped, the pressing and separating block 604 04 moves to the center of the I-beam, the downward-pressed separation block 604 is no longer squeezed, the retaining spring 605 resets the downward-pressed separation block 604, and the wedge block 8 is plugged into the connecting component 6 to prevent the wedge block 8 from rotating inside the connecting component 6. The downward-pressed separation block 604 is stuck in the gap of the interactive block 7, reducing the time and process required for high-position and low-position connections. Since the connecting component 6 is operated underwater, it is inevitable that it will be subjected to pressure from the outside to the inside, so the downward-pressed separation block 604 will only be squeezed in the direction of the interactive block 7, and will not open, so it will not loosen.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
