Description

Technical Field

[0001] This invention relates to the field of oil drilling equipment technology, and in particular to a dual-purpose mouse hole chuck. Background Technology

[0002] In oil and gas drilling operations, mouse holes are crucial facilities at the well site for the temporary storage and preparation of drill pipe stands. When it is necessary to connect a single drill pipe into two or three stands, slip devices within the mouse hole are typically used to secure the tubing for threaded connection. Existing mouse hole slip devices primarily function to clamp and position the drill collar, drill pipe, and casing using mechanical structures or hydraulic drives, ensuring the tubing remains stationary during connection. These devices typically consist of a base, a clamping body, and a drive component. The radial contraction of the internal clamping head grips the outer wall of the tubing, thus bearing the weight of the tubing and preventing rotation, providing a stable working platform for wellhead operators.

[0003] Existing mouse hole slips have a relatively limited function, only enabling static clamping of the tubing string. When performing drill string connection operations, if it is necessary to rotate the tubing string to assist in thread alignment or tightening, it often requires the assistance of external power tongs or other independent rotating equipment, or frequent disassembly and replacement of different special tools to achieve the rotation function, resulting in low drilling efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-purpose mouse hole locator, which solves the technical problem of the single function of existing mouse hole locators.

[0005] This application discloses a dual-purpose mouse hole kava, comprising: Base; A rotating mechanism is mounted on the base; A cylindrical body is installed at the output end of the rotating mechanism, and a clamping cavity is provided inside the cylindrical body; The base plate is installed at the output end of the rotating mechanism; A lifting mechanism is installed at the output end of the rotating mechanism; A clamping mechanism is disposed inside the clamping cavity, and the clamping mechanism is connected to the output end of the lifting mechanism.

[0006] This application is equipped with a lifting mechanism and a clamping mechanism. The lifting mechanism drives the clamping or opening action of the clamping mechanism to complete the clamping or releasing of the sleeve. Combined with the rotating mechanism, the rotating action can be realized to complete the column operation.

[0007] Based on the above technical solution, the present application can be further improved as follows: Furthermore, the clamping mechanism includes: A disc is installed at the output end of the lifting mechanism; The linkage unit has one end mounted on the disk and the other end extending into the clamping cavity; Several clamp heads are installed at the end of the connecting rod unit, and the outer wall of the clamp head contacts the inner wall of the clamping cavity; The jaw plate is installed on the inside of the pliers head. The beneficial effect of this step is that the sleeve can be stably clamped by using the pliers head and the jaw plate.

[0008] Furthermore, the inner wall of the clamping cavity is provided with at least two inclined sections and at least one transition section. The transition section is located between the two inclined sections, and the angle between the transition section and the horizontal plane is greater than the angle between the inclined sections and the horizontal plane. The advantage of this step is that it facilitates subsequent segmented clamping.

[0009] Furthermore, it also includes a guide rod, which is vertically mounted on the base plate, and the top of the guide rod engages with the disc. The beneficial effect of this step is to ensure the stability of the disc's movement trajectory, thereby ensuring the stability of the clamping head.

[0010] Furthermore, the lifting mechanism is a lifting hydraulic cylinder, there are two lifting hydraulic cylinders, and there are two guide rods. The guide rods and the lifting hydraulic cylinders are arranged alternately. The beneficial effect of this step is to ensure the stability during lifting.

[0011] Furthermore, the clamps have at least four heads.

[0012] Furthermore, the linkage unit includes: Support, mounted on the disc; The first link is hinged to the support; The second link is hinged to the end of the first link, and the pliers head is installed at the end of the second link.

[0014] Furthermore, the rotating mechanism includes: The gearbox is mounted on the base. A hydraulic motor is mounted on the gearbox; A turntable is installed at the output end of the gearbox.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application provides a dual-purpose mouse hole clamp, which uses a lifting mechanism to drive the clamping mechanism to move up and down, thereby moving the clamp heads in opposite directions or in opposite directions to complete the function of clamping or releasing the sleeve. Subsequently, a rotating mechanism can be used to achieve rotation, thereby completing the function of the column.

These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0024] Example: In oil drilling operations, mousehole slips are used to temporarily store individual drill pipes or standpipes for quick connection during tripping in and out of the drill string. Traditional mousehole slips typically only have a single holding function: securing the drill string inside the mousehole when needed or releasing it upon deployment. However, when connecting a standpipe, an additional power source or manual assistance is often required to rotate the drill string to achieve threaded connection. This not only increases the number of steps and reduces efficiency but also poses certain safety hazards.

[0025] To solve the above problems, such as Figure 1-3 As shown, this application discloses a dual-purpose mouse hole cardiopyrrolidone, comprising: Base 1; Rotating mechanism 2 is mounted on the base 1; The cylinder 3 is installed at the output end of the rotating mechanism 2, and the inside of the cylinder 3 is provided with a clamping cavity 4; The base plate 5 is installed at the output end of the rotating mechanism 2; The lifting mechanism 6 is installed at the output end of the rotating mechanism 2; The clamping mechanism 7 is disposed inside the clamping cavity 4, and the clamping mechanism 7 is connected to the output end of the lifting mechanism 6.

[0026] The base 1 serves as the mounting foundation, providing a stable support platform to bear the weight of the components and the working load. The subsequent rotating mechanism 2 is mounted on the base 1, which can drive the rotating platform to rotate, thus enabling rotation to complete the threaded connection. The interior of the cylinder 3 is used for clamping, and the clamping and releasing action can be achieved through a clamping and releasing mechanism to meet customer needs.

[0027] To ensure stable and uniform clamping of the drill string subsequently, the clamping mechanism 7 includes: Disc 701 is installed at the output end of the lifting mechanism 6; The connecting rod unit 702 is mounted on the disk 701 at one end and extends into the clamping cavity 4 at the other end; Several clamp heads 703 are installed at the end of the connecting rod unit 702, and the outer wall of the clamp head 703 is in contact with the inner wall of the clamping cavity 4; The jaw plate 704 is installed on the inside of the pliers head 703.

[0028] The disc 701 is used to support and realize the synchronous lifting and lowering of multiple jaws 703 in the subsequent clamping mechanism 7, so as to clamp the drill string more stably. The connecting rod unit 702 is a hinged assembly. When the lifting mechanism 6 moves up and down, it can drive the jaws 703 to move up and down to complete the clamping action.

[0029] The clamping heads 703 in this application are at least four, which ensures the stability of the clamping.

[0030] The clamp head 703 in this application needs to clamp inwards when moving downwards and open outwards when moving upwards. Therefore, the inner wall of the clamping cavity 4 is inclined. Specifically, the inner wall of the clamping cavity 4 is provided with at least two inclined sections 401 and at least one transition section 402. The transition section 402 is located between the two inclined sections 401, and the angle between the transition section 402 and the horizontal plane is greater than the angle between the inclined section 401 and the horizontal plane. By designing multiple inclined sections, segmented clamping is achieved. When clamping downwards, the clamp head 703 first passes through the upper inclined section and gradually retracts inwards to contact the tubing. As it continues to descend, the clamp head 703 enters the transition section 402. Due to the increased inclination angle of this section, the radial position of the clamp head 703 is quickly locked or subjected to stronger support force, thereby completing a reliable clamping action. Conversely, when it is necessary to release, the clamp head 703 moves upwards through the transition section 402 back to the inclined section 401, and the radial constraint is released. To further ensure the stability of the lifting and lowering movement of the disc 701, this application also includes a guide rod 8, which is vertically installed on the base plate 5, and the top of the guide rod 8 cooperates with the disc 701. The disc 701 can lift and lower along the guide rod 8, thus ensuring the lifting and lowering trajectory, which in turn ensures the movement trajectory of the clamping mechanism 7, achieving stable clamping.

[0031] Specifically, the lifting mechanism 6 is a lifting hydraulic cylinder, there are two lifting hydraulic cylinders 6, and there are two guide rods 8, which are staggered and spaced apart from the lifting hydraulic cylinders.

[0032] This application achieves synchronous movement through the cooperation of the disc 701 and the linkage unit 702. Since there are multiple clamp heads 703, the linkage unit 702 is required for hinged engagement. Specifically, the linkage unit 702 includes: Support 705 is mounted on the disk 701; The first connecting rod 706 is hinged to the support 705; The second link 707 is hinged to the end of the first link 706, and the pliers head 703 is installed at the end of the second link 707. This application uses multiple links to hinge and change direction to complete the connection with the pliers head. The support 705 is provided on the upper surface of the support 705. At least two links 707 need to be adjusted in direction to better connect the pliers head 703.

[0033] The cylindrical body 3 is a cone with a larger inner diameter at the top and a smaller inner diameter at the bottom.

[0034] The rotating mechanism 2 in this application can be an existing rotating mechanism that provides rotational function, or it can have the following structure, including: Gearbox 201 is mounted on the base 1; Hydraulic motor 202 is mounted on the gearbox; The turntable 203 is installed at the output end of the gearbox 201. Specifically, it can be installed on the driven gear of the gearbox 201, and the driving gear is engaged with the hydraulic motor 202.

[0035] To further explain this application, When pipe string clamping is required, the lifting mechanism 6 is activated, driving the clamping mechanism 7 to move axially within the clamping cavity 4. Due to the fit between the inner wall of the clamping cavity 4 and the outer side of the clamping mechanism 7 (the inner wall of the clamping cavity 4 is inclined), the clamping head 703 contracts radially during the movement of the clamping mechanism 7, thus tightly gripping the pipe string located in the center. When the pipe string needs to be released, the lifting mechanism 6 reverses its movement, causing the clamping mechanism 7 to move in the opposite direction. The clamping mechanism 7 expands radially, and the clamping head 703 releases the pipe string. During or after this process, if a column connection operation is required, the rotating mechanism 2 is activated, driving the lifting mechanism 5 and the clamping mechanism 6 to rotate.
