DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1 - Figure 9 A throttling and well-killing manifold adjustment device includes a mounting base 1, which is a rectangular frame with openings on the front and bottom. A U-shaped limiting groove 2 for limiting the manifold is provided on the top and left and right sides of the mounting base 1. Limiting blocks 3 for limiting the manifold from separating from the limiting groove 2 are movably installed on the two horizontal sections of the limiting groove 2. Supporting bases 4 for supporting the manifold are symmetrically arranged on the left and right sides of the mounting base 1. A driving mechanism 5 for driving the limiting blocks 3 and the supporting base 4 is installed on the mounting base 1.

[0031] The driving mechanism 5 includes a moving unit 51 installed on the mounting base 1 for driving the limit block 3 to move toward the center of the arc of the limit groove 2, and a lifting unit 52 for pushing the support base 4 to move upward. Positioning components 53 are installed on the left and right sides of the mounting base 1 to limit the downward movement of the support base 4.

[0032] A movable lifting platform 7 is installed at the bottom of the mounting seat 1 for pushing the manifold up and down to align with the wellhead.

[0033] A positioning mechanism 6 for vertically aligning the manifold and the wellhead mounting hole is installed on the rear inner wall of the mounting seat 1 .

[0034] During specific use, with the four-way pipe manifold as the center, the mounting base 1 is moved from the back to the front and is sleeved on the outside of the four-way pipe, so that the limit groove 2 is respectively installed on the pipes on the left, top and right sides of the manifold, and the interface at the bottom of the manifold is exposed from the bottom of the mounting base 1. The limit block 3 is driven by the moving unit 51 to move in the direction close to the arc center of the limit groove 2, so that the limit block 3 is pressed tightly on the front side of the pipes on the top, left and right sides of the manifold. The limit groove 2 is distributed in the up and down and left and right directions, respectively, and can limit the pipes in the up and down and left and right directions respectively. The mounting base 1 and the limit block 3 can limit the pipes in the front and back directions, thereby improving the firmness of the fixation of the manifold.

[0035] While the moving unit 51 pulls the limit block 3 to tighten, the lifting unit 52 pushes the support seat 4 to move upward, so that the support seat 4 is supported on the left and right sides of the pipe away from the end of the four-way, further improving the stability of the manifold during movement, preventing the manifold from shaking during movement, and improving the accuracy of installation of the manifold and the wellhead.

[0036] See also Figure 3 and Figure 4 The mounting seat 1 is provided with a slide groove 11 which is parallel to the horizontal section of the limit groove 2, and the slide groove 11 is provided with a guide groove 12 which is symmetrically distributed about the limit block 3. The rear side of the guide groove 12 is inclined toward the direction close to the arc center of the limit groove 2, and the limit block 3 is fixedly connected with a guide block 31 which slides with the guide groove 12.

[0037] During specific use, in the initial state, the limit block 3 is located at the front end of the guide groove 12. At this time, the limit block 3 is completely hidden inside the slide groove 11 to avoid affecting the installation of the limit groove 2 on the pipe of the manifold. When the pipe is installed in the limit groove 2, the moving unit 51 drives the limit block 3 to move along the guide groove 12, so that the limit block 3 can move toward the center of the arc of the limit groove 2, so that the limit block 3 blocks the pipe and prevents the pipe from detaching from the limit groove 2.

[0038] See also Figure 3 - Figure 5 The moving unit 51 includes a movable plate 511 that is installed inside the mounting base 1 for sliding back and forth and corresponds one-to-one with the limit block 3. The rear side of the limit block 3 is slidingly connected to the front side of the movable plate 511. The mounting base 1 is equipped with a moving component for driving several movable plates 511 to move back and forth synchronously.

[0039] See also Figure 3 - Figure 5 The moving assembly includes a lead screw 512 that is rotatably installed inside the mounting base 1 and corresponds one-to-one to the limit slot 2. The external thread of the lead screw 512 is connected to a concave frame 513. The concave frame 513 is slidably installed inside the mounting base 1. The front ends of the two ends of the concave frame 513 are fixedly connected to the corresponding movable plate 511. The rear end of the lead screw 512 passes through the rear of the mounting base 1 and is fixedly connected to a transmission gear 514. A driving gear 515 is rotatably installed on the rear side of the mounting base 1, and several transmission gears 514 are engaged with the driving gear 515.

[0040] During specific use, the driving gear 515 is rotated clockwise to drive multiple transmission gears 514 to rotate together, and then the transmission gear 514 drives the corresponding screw 512 to rotate, and the screw 512 is used to drive the corresponding concave frame 513 to move backward, so that the concave frame 513 pulls the corresponding movable plate 1 511 to move backward, and the movable plate 1 511 drives the corresponding limit block 3 to move backward together. During the backward movement, the limit block 3 will move toward the center of the limit groove 2 under the guidance of the guide groove 12, so that the limit block 3 can block and limit the pipeline.

[0041] See also Figure 3 、 Figure 5 and Figure 6The lifting unit 52 includes a tripod 521 that is slidably installed on both sides of the mounting base 1. A telescopic rod 522 is fixedly installed on the top of the tripod 521. The telescopic section of the telescopic rod 522 away from the center of the mounting base 1 is fixedly connected to the bottom of the support base 4. A fixing component 523 for fixing the telescopic section is installed on the fixed section of the telescopic rod 522. A connecting frame 524 is fixedly connected between the rear sides of the left and right tripods 521. The connecting frame 524 is slidably installed on the rear side of the mounting base 1. The top of the connecting frame 524 is fixedly connected to a driving frame 525 located on the rear side of the mounting base 1. The rear side of the driving gear 1 515 is coaxially fixedly connected to the driving gear 2 526. The driving gear 2 526 is located on the inner side of the driving frame 525. The left inner wall of the driving frame 525 is provided with meshing teeth that engage with the driving gear 2 526.

[0042] During specific use, when the mounting base 1 is mounted on the manifold cross-piece from back to front, the support base 4 moves to just below the pipes on the left and right sides. When the driving gear 1 515 rotates clockwise, the driving gear 1 515 drives the driving gear 2 526 to rotate together, and the driving frame 525 is driven to move upward by the driving gear 2 526. The driving frame 525 pulls the connecting frame 524 to move upward, and the connecting frame 524 drives the tripods 521 and telescopic rods 522 on the left and right sides to move upward together, so that the telescopic rod 522 pushes the support base 4 to move upward to support the end of the pipe away from the mounting base 1, thereby improving the stability of the pipe during movement.

[0043] The telescopic rod 522 can be telescopically adjusted according to the length of the pipes on the left and right sides, so that the support base 4 can support pipes of different lengths, thereby improving the applicability of the device. The tripod 521 and the fixed section of the telescopic rod 522 form a triangular structure, which improves the firmness of the support for the telescopic rod 522.

[0044] See also Figure 3 and Figure 6 The fixing assembly 523 includes a shaft rod 5231 rotatably mounted on the front side of the fixed section of the telescopic rod 522, and a limiting member 5232 is rotatably mounted on the shaft rod 5231. A torsion spring 5233 is fixedly connected between the fixed section of the telescopic rod 522 and the limiting member 5232, and is used to push the limiting member 5232 to rotate backward. The torsion spring 5233 is sleeved on the shaft rod 5231, and a plurality of limiting grooves 5234 equidistantly distributed on the left and right are opened on the front side of the telescopic section of the telescopic rod 522. The end of the limiting member 5232 away from the center of the mounting seat 1 is plugged into the limiting groove 5234 backward.

[0045] When the lever 522 is in the upright position, the spring 5233 is released to engage the stopper 5232 and the stopper 5234, thereby securing the lever 522 in a secure position.

[0046] See also Figure 2 - Figure 5 The rear side of the mounting base 1 is fixedly connected to a shell 13 that covers the outside of the transmission gear 514, the driving gear 1 515 and the driving gear 2 526. The driving frame 525 is connected to the shell 13 for sliding up and down. The rear side of the shell 13 is fixedly connected to the driving motor 54. The front end of the output shaft of the driving motor 54 rotates and passes through the interior of the shell 13 and is coaxially fixedly connected to the driving gear 2 526.

[0047] During specific use, the shell 13 plays a shielding and protective role for the transmission gear 514, drive gear 1 515 and drive gear 2 526, preventing dust from falling on the transmission gear 514, drive gear 1 515 and drive gear 2 526, which is conducive to the smooth transmission of the transmission gear 514, drive gear 1 515 and drive gear 2 526; when working, the drive motor 54 drives the drive gear 2 526 and the drive gear 1 515 to rotate, so that the drive gear 1 515 and the drive gear 2 526 drive the transmission gear 514 and the drive frame 525 respectively.

[0048] Please refer to the figure Figure 3 and Figure 7 The positioning assembly 53 includes a pull rod 531 that slides left and right and is installed on the vertical section of the tripod 521. A blocking piece 532 is fixedly connected to the pull rod 531. The blocking piece 532 is slidably installed inside the vertical section of the tripod 521. A return spring 533 is fixedly connected between the side of the blocking piece 532 away from the center of the mounting seat 1 and the inner wall of the tripod 521. A slide rail 534 is fixedly connected to the side of the mounting seat 1 close to the tripod 521. The vertical section of the tripod 521 is slidably connected to the slide rail 534 up and down. A number of positioning holes 535 are equidistantly distributed up and down are opened on the slide rail 534. The end of the pull rod 531 close to the center of the mounting seat 1 is wedge-shaped and is plugged into the slide rail 534.

[0049] When in use, in the initial state, the return spring 533 is in a compressed state, and the end of the pull rod 531 close to the center of the mounting seat 1 is inserted into the interior of the positioning hole 535. When the tripod 521 moves upward along the slide rail 534, the tripod 521 drives the pull rod 531 to move upward together. When the pull rod 531 moves upward, the side wall of the positioning hole 535 conflicts with the inclined surface of the end of the pull rod 531 close to the center of the mounting seat 1 and pushes the pull rod 531 to move away from the center of the mounting seat 1, so that the end of the pull rod 531 The first part of the tripod 521 is separated from the positioning hole 535. At this time, the return spring 533 is further compressed. When the tripod 521 moves upward to a suitable height, the return spring 533 is used to push the blocking piece 532 and the pull rod 531 toward the center of the mounting base 1, so that the end of the pull rod 531 is reinserted into the corresponding positioning hole 535, and the tripod 521 is locked again to prevent the tripod 521 and the telescopic rod 522 from moving downward, thereby improving the firmness of the tripod 521 and the telescopic rod 522 in supporting the support base 4.

[0050] See also Figure 3 and Figure 8 The positioning mechanism 6 includes a movable plate 61 that is slidably mounted on the inner wall of the rear side of the mounting seat 1. A return spring 62 is fixedly connected between the top of the movable plate 61 and the inner wall of the mounting seat 1. The bottom of the front end of the movable plate 61 is fixedly connected to an insertion rod 63, and a push piece 64 is fixedly connected to the insertion rod 63.

[0051] During specific use, when installing the manifold into the mounting seat 1, push the push piece 64 upward to move the insertion rod 63 to the top of the manifold mounting hole. At this time, the return spring 2 62 is in a compressed state to avoid affecting the installation and fixation of the manifold by the mounting seat 1. When the manifold is installed in the mounting seat 1, release the push piece 64. At this time, the rebound force of the return spring 2 62 is used to push the movable plate 2 61 downward to insert the insertion rod 63 into the mounting hole on the rear side of the manifold.

[0052] See also Figure 1 、 Figure 2 and Figure 9 The mobile lifting platform 7 includes a mobile base 71 located below the mounting base 1. A lifting frame 72 is fixedly installed on the top of the mobile base 71. The top of the lifting frame 72 is fixedly connected to the bottom of the mounting base 1. A U-shaped limiting groove 3 73 is opened on the front side of the mobile base 71. The limiting groove 3 73 is aligned with the limiting groove 1 2 at the top. A number of rollers 74 are evenly installed circumferentially on the arc wall of the limiting groove 3 73.

[0053] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9When the manifold is fixed to the mounting seat 1, the lifting frame 72 pushes the mounting seat 1 upward, lifts the manifold upward to the top of the wellhead, and then moves the movable seat 71 to the wellhead, so that the limit groove 3 73 is sleeved on the outside of the wellhead, and the arc wall of the limit groove 3 73 fits the outer ring wall of the wellhead. At this time, the interface at the bottom of the manifold and the wellhead are docked together. When the mounting hole of the manifold and the mounting hole of the wellhead are misaligned up and down, the edge of the wellhead will push the plug rod 63 to move upward. At this time, the movable seat 71 is pushed around the wellhead to rotate, so that the mounting seat 1 drives the manifold to rotate and adjust. When the mounting hole of the manifold is aligned with the mounting hole of the wellhead, the rebound force of the return spring 2 62 pushes the movable plate 2 61 and the plug rod 63 downward, so that the bottom end of the plug rod 63 is plugged into the mounting hole of the wellhead. At this time, the manifold cannot continue to rotate, which is convenient for quickly and accurately docking the manifold and the wellhead, and convenient for subsequent use of bolts to connect the manifold and the wellhead.

[0054] During the rotation of the movable seat 71 , the roller 74 contacts the outer ring wall of the wellhead, which can reduce the friction between the movable seat 71 and the wellhead, so that the movable seat 71 can be rotated and adjusted smoothly.

[0055] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, integral or sliding connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0056] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
