Description

Technical Field

[0001] The present invention relates to the field of slip-type chucks, in particular to an intelligent wireless electric chuck. Background Art

[0002] The slip chuck is a device used during casing running operations in oil and gas production. Existing casing running operations typically utilize a combination of casing elevators and casing slips. The hydraulic cylinder in a traditional slip chuck is powered by a large hydraulic station and is connected to numerous external pipelines, resulting in a complex structure. Due to the external pipelines, the hydraulic chuck cannot rotate with the turntable, and the chuck needs to be separated from the turntable during drilling. Furthermore, due to the high levels of carbon dioxide and hydrogen sulfide in oil wells, they can corrode the tubing over time. Furthermore, existing slips experience vertical relative displacement when clamping the tubing, which can easily cause scratches on the tubing's outer surface, thereby accelerating acidic corrosion of the tubing surface.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention uses a micro power station to power the hydraulic cylinder and a wireless module to achieve remote wireless control of the slips, simplifying the system and reducing costs. It also eliminates the need for a large hydraulic station and numerous hydraulic pipelines and valves. During drilling, the hydraulic chuck and turntable can rotate together without having to be separated.

[0014] 2. The movable module of the present invention is composed of a first movable block and a second movable block. The first movable block and the slip mounting hole, as well as the second movable block and the first movable block, are both slidably arranged. A transverse plate, a limit column, an anti-drop cap, and a spring are also provided. When clamping the oil pipe, the second movable block drives the slip body to clamp the oil pipe and can remain relatively stationary horizontally, while the first movable block can continue to move downward to generate a lateral thrust on the second movable block. This can reduce the vertical relative displacement between the slip body and the oil pipe, thereby reducing wear on the outer wall of the oil pipe and reducing the possibility of corrosion by acidic media.

[0015] 3. The present invention adds a support arm with a pressure wheel, which drives the wire rope, reel, first gear and rack stored in the support arm, as well as the torsion spring that drives the support arm to expand. After the slip body is released, the support arm can be opened synchronously to allow the pressure wheel to abut the oil pipe. When the oil pipe breaks and falls, the pipe joint can be locked without affecting the lifting of the oil pipe, reducing the risk of pipe detachment and improving safety.

[0016] 4. The present invention adds a shrinkage hole gas regulating mechanism. When the slip body clamps the oil pipe, the shrinkage hole gas regulating mechanism reduces the channel, which can reduce the possibility of acidic medium corroding the hydraulic cylinder. When the slip body releases the clamping, the shrinkage hole gas regulating mechanism increases the channel, which facilitates the lifting or lowering of the oil pipe.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0028] Figure 1 This is a schematic diagram of the structure of the intelligent wireless electric chuck of the present invention. Figure 2 It is a half-section schematic diagram of the intelligent wireless electric chuck of the present invention.

[0029] The embodiment of the present invention provides an intelligent wireless electric chuck, such as Figure 1 and Figure 2As shown, it is composed of two centrally symmetrical semicircular chuck halves 1 on the left and right, which are connected by a vertical hinge pin 101 to form a chuck body. A cava mounting hole 102 is provided in the middle of the chuck body, and four cava bodies 2 and a hydraulic cylinder 3 for driving each cava body 2 to move and clamp are arranged in the cava mounting hole 102; the chuck body is cross-distributed in the circumference and embedded with a micro power station 4, a control valve group module 5, a battery module 6 and a hydraulic oil tank 7; a movable module 8 is provided in the cava mounting hole 102; and a shrinkage hole air regulating mechanism 9 is fixedly installed on the bottom surface of the chuck body.

[0030] Based on the above embodiment, the slip mounting hole 102 is a wedge-shaped structure having a first slope surface 1021 and two opposite first vertical surfaces 1022 .

[0031] Figure 9 This is a diagram of the electrical connections of the intelligent wireless electric chuck of the present invention.

[0032] Based on the above embodiments, Figure 9 As shown, the micro power station 4 includes a drive motor 401, a high-pressure pump 402, a low-pressure pump 403, and a controller 404. The drive motor 401 draws hydraulic oil from the hydraulic oil tank 7 through the high-pressure pump 402 and the low-pressure pump 403, and then delivers the hydraulic oil to each hydraulic cylinder 3 through the control valve group module 5. The hydraulic oil is connected and transported by hydraulic pipelines. The drive motor 401 is also electrically connected to the motor driver 4011. The motor driver 4011 and the control valve group module 5 are both electrically connected to the controller 404. The controller 404 is connected to the host computer 10 via a wireless module 4041.

[0033] During use, the controller 404 receives instructions from the host computer 10 through the wireless module 4041, and controls the operation of the drive motor 401 by controlling the motor driver 4011. The drive motor 401 drives the high-pressure pump 402 and the low-pressure pump 403 to supply oil to the four hydraulic cylinders 3. A pressure sensor is installed in the hydraulic pipeline connected to the hydraulic cylinder 3. The oil pressure in the hydraulic cylinder 3 is monitored by the pressure sensor, and the control valve group module 5 is used to realize oil quantity control and reversing, thereby controlling the extension or retraction of the piston rod of the hydraulic cylinder 3.

[0034] Figure 3 is a schematic diagram of the mobile module in the present invention, Figure 8 Schematic diagram of the structure of the chuck body in the present invention.

[0035] Based on the above embodiments, Figure 3As shown, the movable module 8 is composed of a first movable block 801 and a second movable block 802. The first movable block 801 is a wedge-shaped structure, slidingly arranged along the first slope 1021, and has two opposing second slopes a8011 and a second slope b8012, as well as two opposing second vertical surfaces 8013. The second movable block 802 is a wedge-shaped structure, slidingly arranged along the second slope b8012, and has two opposing third slopes 8021 and a third vertical surface a8022, as well as two opposing third vertical surfaces b8023. The slip body 2 is fixedly mounted on the third vertical surfaces a8022. The top of the second movable block 802 has a horizontal plate 8024 extending horizontally toward the first movable block 801. A long hole is formed in the horizontal plate 8024, and the horizontal plate 8024 is arranged to fit the top surface of the first movable block 801. A limiting post 8014 is connected to the top of the first movable block 801, which passes through the long hole. A locking cap 8015 is connected to the top of the limiting post 8014. A spring 8016 is squeezed between the horizontal plate 8024 and the locking cap 8015. Furthermore, a mounting seat 103 is fixed to the chuck body above the slip mounting hole 102. A hydraulic cylinder 3 is mounted on the mounting seat 103. A housing 8017 for accommodating the hydraulic cylinder 3 is formed in the first movable block 801. A hinge seat 8018 is formed at the bottom of the first movable block 801, and the piston rod of the hydraulic cylinder 3 is hingedly connected to the hinge seat 8018. When clamping the oil pipe, the piston rod of the hydraulic cylinder 3 moves downward and drives the first moving block 801 to slide downward along the first slope 1021. The first moving block 801 drives the second moving block 802 to move downward and inward until the slip body 2 on the second moving block 802 clamps the oil pipe. Since the second moving block 802 can move relatively along the second slope b8012 of the first moving block 801, the second moving block 802 can remain relatively still when driving the slip body 2 to clamp the oil pipe, and the first moving block 801 can continue to move downward so that the second moving block 802 only produces horizontal displacement, so that the slip body 2 on the second moving block 802 further clamps the oil pipe. Since the vertical relative displacement of the slip body 2 and the oil pipe is reduced during the clamping process, the wear of the slip body 2 on the outer wall of the oil pipe can be reduced, and the possibility of corrosion by acidic media can be reduced.

[0036] Based on the above embodiments, Figure 8 As shown, guide bars 8019 are provided on each of the two opposing second vertical surfaces 8013. The guide bars 8019 have the same slope as the first slope 1021. Guide grooves 1023 are provided on the two opposing first vertical surfaces 1022, which slidably engage with the guide bars 8019. Furthermore, a slide rail (not shown) is provided along the slope of the second slope b 8012, and a corresponding slide groove (not shown) is provided on the third slope 8021.

[0037] Figure 4 for Figure 2The enlarged view of the middle A part, Figure 5 for Figure 2 Enlarged view of part B in the middle.

[0038] Based on the above embodiments, Figure 4 Combine Figure 3 As shown, the chuck body is located on the upper and lower parts of the first slope 1021, respectively, with a first inner groove 104 and a second inner groove 105. A first rotating shaft 1041 is provided between the inner walls of the first inner groove 104 for damped rotation. A winding wheel 1042 and a first gear 1043 are fixed on the first rotating shaft 1041. A steel wire rope 1045 is wound around the winding wheel 1042. A first guide wheel 1046 is installed at the lower edge of the opening of the first inner groove 104. An inner concave hole 80111 is formed in the upper middle section of the second slope a8011, which is connected to the accommodating chamber 8017. A fixing plate 80112 is installed at the inner concave hole. A rack 1044 is fixed on the fixing plate 80112. The rack 1044 is spaced apart from the first slope 1021. The first gear 1043 partially extends into the inner concave hole and meshes with the rack 1044. Figure 5 As shown, a second guide wheel 1054 is installed at the upper edge of the opening of the second inner groove 105, a third guide wheel 1055 is installed in the second inner groove 105, a support arm 1051 is hingedly provided in the second inner groove 105, a torsion spring 1052 is installed at the hinge of the support arm 1051, the free end of the wire rope 1045 is connected to and pulls the support arm 1051 after passing through the first guide wheel 1046, the second guide wheel 1054 and the third guide wheel 1055, and a pressure wheel 1053 is installed at the free end of the support arm 1051.

[0039] When the first movable block 801 moves up to its position, the rack 1044 engages the first gear 1043 and drives the reel 1042 to release the line. The support arm 1051 is deflected to the pressure wheel 1053 under the action of the torsion spring 1052 to abut the oil pipe. Once the risk of the oil pipe breaking off and falling occurs, the pipe section will press down on the four pressure wheels 1053 due to its radially convex structure, so that the pressure wheels 1053 can lock the pipe section and prevent the pipe section from falling further. At the same time, it does not affect the lifting of the oil pipe, reducing the risk of the pipe breaking off and improving safety. When the first movable block 801 moves down, the rack 1044 engages the first gear 1043 and drives the reel 1042 to reel in the line. The support arm 1051 rotates back to the second inner groove 105 under the traction of the wire rope 1045. The first movable block 801 continues to move down to achieve the clamping effect of the slip body 2.

[0040] Figure 6 Schematic bottom view of the shrinkage hole gas regulating mechanism in the present invention, Figure 7 Schematic top view of the shrinkage hole gas adjustment mechanism in the present invention. The principle of the shrinkage hole gas adjustment mechanism 9 is similar to that of the aperture adjustment mechanism.

[0041] Based on the above embodiments, Figure 6 and Figure 7 As shown, the shrinkage hole gas regulating mechanism 9 includes a base 901, which is annular in structure and fixedly arranged on the bottom surface of the chuck body. A plurality of blades 903 that can rotate to form channels of different sizes are circumferentially arranged in the base 901. A rotating disk 904 for adjusting the rotation of the blade 903 is rotatably provided at the bottom of the base 901, and a disk 902 for limiting the rotating blade 903 to form channels of different sizes is fixedly provided in the upper part of the base 901. Specifically, a limiting column 9031 is rotatably provided on the upper surface of the blade 903, and a limiting strip 9032 is fixedly provided on the lower surface of the blade 903. A limiting hole 9021 for limiting the moving trajectory of the limiting column 9031 is provided on the disk 902, and a limiting long groove 9041 for limiting the moving trajectory of the limiting strip 9032 is provided on the rotating disk 904.

[0042] The outer wall of the rotating disk 904 is connected to the hinge of the support arm 1051 for transmission. Specifically, the outer wall of the rotating disk 904 is fixedly sleeved with an outer ring gear 1056, and the hinge of the support arm 1051 is coaxially connected to the first bevel gear 1057. The bottom surface of the chuck body is rotatably connected to the vertical shaft 1058. The upper section of the vertical shaft 1058 is fixedly connected to the horizontal second bevel gear 1059. The tooth surface of the second bevel gear 1059 meshes with the tooth surface of the first bevel gear 1057, and the lower end of the vertical shaft 1058 is fixedly connected to the second gear 1060. The second gear 1060 is meshed with the outer ring gear 1056. Therefore, when the support arm 1051 rotates, it can drive the second bevel gear 1059, the second gear 1060, the outer ring gear 1056 and the rotating disk 904 to rotate in sequence through the first bevel gear 1057, and the rotating disk 904 can cooperate with the disk 902 to adjust the opening angle of the blade 903. When the slip body 2 moves downward and clamps the oil pipe, the blades 903 of the shrinking hole gas regulating mechanism 9 reduce the passageway, reducing the possibility of acidic media corroding the hydraulic cylinder 3. When the slip body 2 moves upward and releases the clamp, the blades 903 of the shrinking hole gas regulating mechanism 9 increase the passageway, facilitating the lifting or lowering of the oil pipe. It should be noted that if the oil pipe needs to be lifted, the support arm 1051 can be placed in a semi-retracted position. In this position, the slip body 2 is opened, and the passageway of the shrinking hole gas regulating mechanism 9 is also semi-open (not fully open). This position facilitates the upward and downward lifting of the oil pipe, but does not pose the risk of the pipe falling out. If the pipe needs to be prevented from falling out (no lifting is required), the support arm 1051 can be placed in an open position. In this position, the slip body 2 is retracted, and the passageway of the shrinking hole gas regulating mechanism 9 is fully open. If the oil pipe needs to be clamped, the support arm 1051 is retracted, and the passageway of the shrinking hole gas regulating mechanism 9 is closed, reducing the possibility of acidic gas rising and corroding the hydraulic cylinder 3.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated 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 invention, and that the scope of the invention is defined by the appended claims and their equivalents.
