Description

Technical Field

[0001] This utility model relates to the technical field of drilling injection head equipment. More specifically, this utility model relates to a gooseneck remote centering adjustment device. Background Technology

[0002] A gooseneck is a device used in coiled tubing installation equipment. It is installed on top of the injection head and works in conjunction with it. The coiled tubing is placed within the gooseneck's guide groove, guiding and delivering the tubing from the tubing reel to the injection head. Current gooseneck technologies mostly employ a hinged front and rear arc-shaped frame as the main structure. The front arc-shaped frame faces the tubing reel, while the rear arc-shaped frame is closer to the injection head frame. Hydraulic cylinders are used to extend or retract the two arc-shaped frames, allowing them to unfold or fold. However, the gooseneck rests above the injection head, typically at a height of 5-15 meters above the ground. If the gooseneck cannot be aligned with the injection head or wellhead, personnel must use a crane to climb above the injection head, manually adjust and align it, and then fix it in place. This adjustment method is inconvenient, poses safety risks, and is inaccurate. Summary of the Invention

[0003] The purpose of this invention is to provide a remote centering adjustment device for gooseneck tubes, so as to solve the technical problem that the existing technology mainly relies on manual adjustment of gooseneck tubes, which is difficult.

Therefore, they should not be construed as limitations on this utility model.

[0016] like Figure 1-3 As shown, the gooseneck tube remote centering adjustment device of this utility model includes: The base 3 is horizontally connected to the top of the fixing frame 1 of the injection head; The drive mechanism 4 is mounted on the base 3 and located at the bottom of the gooseneck tube 2 away from the oil pipe inlet at the top of the injection head. It includes a motor, a reducer, and a push block 6 arranged sequentially towards the bottom of the gooseneck tube 2. The motor and the reducer are connected by a coupling. The reducer is a worm gear structure. The push block 6 is connected to the corresponding side of the bottom of the gooseneck tube 2. The outer end of the worm gear is connected to the push block 6. Through the extension and retraction of the worm gear of the reducer, the push block 6 drives the gooseneck tube 2 to move back and forth. The limiting mechanism 5 includes an ear plate 7 disposed on at least one side of the bottom of the gooseneck tube 2 in the pushing direction. The ear plate 7 is vertically disposed and the bottom of the ear plate 7 is fixed to the base 3. A guide hole 8 is provided in the middle of the ear plate 7. The guide hole 8 extends along the moving direction of the gooseneck tube 2. A guide post 9 is connected to the bottom of the gooseneck tube 2 facing the ear plate 7. The guide post 9 is perpendicular to the guide hole 8 and has the same outer diameter. The outer end of the guide post 9 passes through the guide hole 8 on the corresponding side and can slide along the extending direction of the guide hole 8. The remote control terminal includes a PLC controller, which is connected to the motor and operates the motor through the PLC controller.

[0017] In the prior art, the overall structure of the injection head includes an outer rectangular three-dimensional frame as a fixing bracket. The base 3 can be a side that covers and is located on the top of the injection head fixing bracket on the side facing the bending direction of the gooseneck tube 2, away from the top port of the continuous tubing inlet injection head, i.e. Figure 1-3 On the right side of the direction shown, the drive mechanism 4 and the limit mechanism 5 are respectively installed at corresponding positions on the base 3. The drive mechanism 4 is connected to the bottom of the gooseneck tube 2, and the drive direction is consistent with the path direction of the gooseneck tube 2 to be moved and adjusted. The push block 6 connects the bottom of the gooseneck tube 2 and the worm gear, and is directly connected to the worm gear by bolt clamping. Because the worm gear does not rotate, there is no need to install bearings. The operating structure principle of the motor and worm gear reducer is existing technology. The controller and motor can be directly used with Panasonic brand products, which will not be described in detail here.

[0018] The limiting mechanism 5 is set on the left or right side of the gooseneck tube 2, or symmetrically arranged on both sides. The ear plate 7 is set in cooperation with the guide post 9. The guide post 9 is limited in the guide hole 8 of the ear plate 7. It moves back and forth synchronously with the gooseneck tube 2 towards the top of the injection head to clamp the tubing inlet. The single-point push of the drive mechanism 4 plays a vertical guiding and limiting role for the gooseneck tube 2. The PLC controller is embedded with common simple logic to remotely control the speed of the motor. The speed is reduced and the torque is increased by the reducer to meet the load requirements. After the gooseneck tube 2 is connected to the injection head, the folding wall of the injection head is unfolded first. Then, this device is used to drive the gooseneck tube 2 to move back and forth to center the injection head clamping center. This allows personnel to adjust the gooseneck tube 2 to center the injection head and wellhead from the remote control room, avoiding manual adjustment operations at height and improving the safety and convenience of the operation.

[0019] The remote centering adjustment device for the gooseneck tube 2 of this utility model includes a base 3 and a remote control terminal. A fixed drive mechanism 4 and a limiting mechanism 5 are integrated and installed on the base 3. The drive mechanism 4 includes a motor and a reducer. The output end of the reducer is connected to the gooseneck tube 2 through a push block 6. A guide post 9 is provided on the side of the gooseneck tube 2, which is vertically limited and laterally slidably connected in the guide hole 8 of the limiting mechanism 5 for vertical limiting and lateral guidance. The motor is controlled by a remotely connected PLC controller. Under the extension and retraction of the worm gear of the reducer, the gooseneck tube 2 is driven to move back and forth toward the inlet end of the oil pipe clamped by the injection head, realizing remote adjustment of the position of the gooseneck tube 2, improving the safety and convenience of operation.

[0020] In another technical solution, such as Figure 1-2 As shown, a stiffening plate 14 is vertically connected to the side of the ear plate 7 facing away from the gooseneck tube 2. The bottom of the stiffening plate 14 is fixed to the top of the base 3 to reinforce the structure of the ear plate 7 and prevent the guide hole 8 from deforming under the force of the guide column 9.

[0021] In another technical solution, such as Figure 1-2 As shown, the stiffening plates 14 on the back side of each ear plate 7 are symmetrically arranged to further improve the overall structural strength of the ear plate 7.

[0022] In another technical solution, such as Figure 1-3 As shown, the system also includes a camera 10 mounted on the base 3, with the camera 10 facing the bottom of the gooseneck tube 2 near the oil pipe inlet at the top of the injection head. The remote control terminal also includes an image display, and the camera 10 is communicatively connected to the image display for real-time transmission of captured images. The remote control terminal may also be equipped with an additional touchscreen image display to remotely display the movement status of the gooseneck tube 2 captured by the camera 10, providing a remote adjustment reference for the drive mechanism 4 of the gooseneck tube 2, thereby improving the quality and safety of remote adjustment.

[0023] In another technical solution, such as Figure 1-2 As shown, a pair of ear plates 7 are arranged opposite each other on the left and right sides of the bottom of the gooseneck tube 2 in the pushing direction, and a pair of guide posts 9 are arranged on the left and right sides of the bottom of the gooseneck tube 2. The pair of guide posts 9 slide simultaneously in the guide holes 8 on the corresponding sides, further improving the balance of the drive mechanism 4 when pushing the gooseneck tube 2 to move back and forth.

[0024] In another technical solution, such as Figure 1-3 As shown, it also includes a bracket 11 fixed on the base 3. A push cylinder 12 is installed on the top of the bracket 11 in a horizontal direction perpendicular to the guide post 9. The telescopic end of the push cylinder 12 is set towards the guide post 9. A C-shaped partition 13 is sleeved on the outside of the telescopic end of the push cylinder 12. A rubber pad is provided on the surface of the partition 13. The inner spacing of the partition 13 is set to match the vertical height of the guide post 9. A distance sensor is set on the outside of the partition 13 facing the guide post 9. The distance sensor is connected to the remote control terminal and is used to monitor the distance to the corresponding position of the guide post 9. The push cylinder 12 is connected to the remote control terminal and is used to extend the partition 13 and embed itself into the end of the guide post 9 after the drive mechanism 4 pushes the gooseneck tube 2 into place.

[0025] The C-shaped spacer 13 has its opening facing the guide post 9. Before the drive mechanism 4 pushes the gooseneck tube 2, the spacer 13 and the distance sensor are installed in the same direction as the theoretical forward and backward movement of the gooseneck tube 2 and perpendicular to the initial position of the guide post 9. When the drive mechanism 4 pushes the gooseneck tube 2, the distance sensor acquires the distance data between itself and the guide post 9 in real time. If the data changes smoothly, it indicates that the pushing state of the gooseneck tube 2 is safe and the adjustment speed is uniform. If the data from the distance sensor changes faster than the change in motor speed, it indicates that the gooseneck tube 2 may be deviating, and attention should be paid to the gooseneck tube. 2. To address safety concerns, a pair of ear plates 7, guide posts 9, and spacers 13 are installed on both sides of the gooseneck tube 2. The distance data measured by the distance sensors on both sides and the consistency of distance changes can be used to observe whether the pushing process is balanced, normal, and stable. After the pushing is in place, the pushing cylinder 12 extends, driving the spacer 13 to move toward the guide post 9 until the opening of the spacer 13 is nested on the guide post 9 on the corresponding side. This helps to strengthen and fix the guide post 9 to the final adjusted position of the gooseneck tube 2, preventing accidental movement of the gooseneck tube 2. At the same time, the rubber layer can also play a certain protective role.

[0026] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the drawings shown and described herein.
