Description

Technical Field

[0001] The utility model relates to the technical field of iron roughnecks, in particular to an integrated iron roughneck. Background Art

[0002] An iron roughneck is an automated or semi-automated mechanical device primarily used for connecting and disconnecting drill pipes on oil drilling platforms. It uses a robotic arm to simulate the movements of a human driller, enabling rapid make-up and make-out of the drill pipe.

[0003] The iron roughneck generally clamps the upper drill rod and the lower drill rod by two pairs of upper and lower screw clamps, and then uses the rotating mechanism on the top to sleeve the upper drill rod on the top of the lower drill rod and rotate it to thread the upper drill rod and the lower drill rod. However, when the screw clamps on the existing iron roughneck clamps clamp drill rods of different thicknesses, the contact areas between the drill rods of different thicknesses and the clamps with different curvatures on the screw clamps are different, which may lead to uneven friction when the screw clamps clamp drill rods of different thicknesses, causing slippage between the screw clamps and the drill rod, affecting the efficiency of making or breaking the drill rod. Moreover, it is difficult to disassemble the existing screw clamps from the iron roughneck, making it inconvenient to replace. Therefore, the utility model aims to provide an integrated iron roughneck that is easy to disassemble the screw clamps. Utility Model Content

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figures 1 to 4 According to an embodiment of the present invention, a technical solution is provided: an integrated iron roughneck, comprising an iron roughneck body 1, a spinner seat 2, which is provided on the iron roughneck body 1 and has an insertion slot 4 formed therein; a spinner pliers 3, a first surface of which is fixed with an insertion block 5, the insertion block 5 being adapted to be movably inserted into the insertion slot 4; and a locking mechanism 6, which is provided between the insertion block 5 and the spinner seat 2 and can selectively fix the insertion block 5 and the spinner seat 2 relative to each other to restrict or allow the insertion block 5 to move relative to the spinner seat 2.

[0026] With the integrated iron roughneck adopting the above structure, when the user needs to replace the spin clamp 3 with a different clamping curvature to clamp drill rods 16 of different thicknesses, first, the relative fixed state between the spin buckle seat 2 and the insertion block 5 is released by the locking mechanism 6, and then, the spin clamp 3 is pulled to disengage the insertion block 5 from the insertion groove 4 on the spin buckle seat 2. After that, the spin clamp 3 that needs to be replaced is prepared, and the insertion block 5 fixed on its first side is inserted into the insertion groove 4 on the spin buckle seat 2. At this time, the insertion block 5 and the spin buckle seat 2 are relatively fixed by the locking mechanism 6 to complete the replacement of the spin clamp 3, which is convenient for the user to stably clamp drill rods 16 of different thicknesses.

[0027] The locking mechanism 6 comprises a locking block 7, a locking rod 8, a limiting block 9, a fixing plate 10 and a spring 11; the fixing plate 10 is L-shaped, and its first end is fixed to the bottom of the spin buckle seat 2, and the bottom of the spin buckle seat 2 is provided with a movable groove 12 connected to the insertion groove 4; the locking block 7 is fixed to the top of the locking rod 8, and the limiting block 9 is sleeved on the locking rod 8. The upper limiting block 9 is movably arranged in the movable groove 12 and can be moved into the insertion groove 4, and the locking rod 8 movably passes through the fixing plate 10, and the limiting block 9 is arranged between the fixing plate 10 and the spin buckle seat 2. The spring 11 is sleeved on the locking rod 8 and elastically abuts the limiting block 9; a locking groove 13 suitable for the movable insertion of the locking block 7 is provided on the insertion block 5, and the locking block 7 is inclined toward the insertion block 5; when the user needs to replace the spin buckle pliers 3, first, pull the locking rod 8, When the locking block 7 is fully inserted into the insertion groove 4 and the locking groove 13 is aligned with the locking block 7, the elastic force of the spring 11 will push the limit block 9 to move the locking rod 8 against the locking rod 8, thereby making the locking block 7 stuck in the locking groove 13, thereby achieving relative fixation of the insertion block 5 and the spin buckle seat 2.

[0028] In this embodiment, a toggle block 14 is fixedly provided at the bottom of the locking rod 8, and the gap between the toggle block 14 and the fixed plate 10 is suitable for the insertion of fingers; when the user needs to pull the locking rod 8, first, the finger or an object suitable for pulling the toggle block 14 is inserted into the gap between the toggle block 14 and the fixed plate 10, and then the toggle block 14 is pulled. The toggle block 14 will provide the user with a fulcrum for pulling the locking rod 8, so that the user can pull the locking rod 8.

[0029] In this embodiment, the toggle block 14 has an inclined toggle opening 15 on one side facing the fixed plate 10; when the user needs to pull the toggle block 14, the toggle opening 15 provides a guide so that the user can insert his finger into the gap more naturally and with less effort.

[0030] In this embodiment, the toggle block 14 is configured to be made of rubber material. The rubber material of the toggle block 14 increases the friction between the toggle block 14 and the user's finger, so that the user is more stable when pulling the toggle block 14 .

[0031] In this embodiment, the spin clamp 3 is configured to be made of rubber material; the spin clamp 3 made of rubber material can increase the friction between the spin clamp 3 and the drill rod 16 to stably clamp the drill rod 16.

[0032] Working principle: When the user needs to replace the spin-lock pliers 3 with different clamping curvatures to clamp drill rods 16 of different thicknesses, first, pull the locking rod 8 to make the locking block 7 exit the locking groove 13. At this time, the user can freely pull the spin-lock pliers 3 to make the insertion block 5 completely disengage from the insertion groove 4 on the spin-lock seat 2, thereby completing the disassembly of the spin-lock pliers 3. Then, the user prepares the spin-lock pliers 3 that needs to be replaced, and aligns the insertion block 5 fixed on the first side with the insertion groove 4 on the spin-lock seat 2 and inserts it. During the insertion process, since the locking block 7 is inclined on one side facing the insertion block 5, the insertion block 5 will gradually squeeze the locking block 7 when moving, causing it to compress the spring 11 and move toward the fixed plate 10, until the insertion block 5 is fully inserted into the insertion groove 4, and when the locking groove 13 is aligned with the locking block 7, the elastic force of the spring 11 will push the limit block 9 to abut and move the locking rod 8, thereby causing the locking block 7 to By inserting the toggle block 14 into the locking groove 13, the insertion block 5 and the spin buckle seat 2 are relatively fixed, which is convenient for the user to stably clamp drill rods 16 of different thicknesses; when the user needs to pull the locking rod 8, first, the user inserts a finger or an object suitable for pulling the toggle block 14 into the gap between the toggle block 14 and the fixed plate 10, and then pulls the toggle block 14. The toggle block 14 will give the user a fulcrum for pulling the locking rod 8, so that the user can pull the locking rod 8; when the user needs to pull the toggle block 14, the toggle mouth 15 provides a guiding role, so that the user can insert his finger into the gap more naturally and with less effort; the toggle block 14 made of rubber material will increase the friction between it and the user's finger, so that the user can be more stable when pulling the toggle block 14; the spin buckle pliers 3 made of rubber material will increase the friction between it and the drill rod 16, so as to stably clamp the drill rod 16.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
