Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, and particularly relates to a drill pipe connection and replacement tool. Background Art

[0002] Drilling equipment is a commonly used equipment in oil exploration and oil production. The power head and the drill pipe are important components of the drilling equipment. Usually, the drill pipe is installed below the power head, and the axis of the drill pipe coincides with the axis of the power head, and both are arranged in the vertical direction. During the drilling process, the drilling equipment sometimes needs to connect and replace the drill pipe. For the drilling equipment used in oil exploration and oil production, the drill pipe has a large size, especially in the vertical direction. When the drill pipe is transported and stored, it is generally placed horizontally; during installation, operators need to use equipment such as a crane to adjust the horizontally placed drill pipe to the vertical direction and then align it with the power head to achieve connection with the power head. During the process of installing, disassembling and replacing the drill pipe, the labor intensity of the operators is large and it takes a long time.

[0003] After retrieval, a Chinese patent with the publication number CN210714524U discloses a drill pipe connection and replacement tool, which includes a mobile robotic arm, a steering mechanism and a drill pipe grasping device; the drill pipe grasping device is installed at the movable end of the mobile robotic arm through the steering mechanism, the mobile robotic arm can drive the drill pipe grasping device to move, and the steering mechanism can drive the drill pipe grasping device to rotate around the axis in the horizontal direction on the mobile robotic arm.

[0004] This tool alleviates the technical problems of high labor intensity and long time consumption of operators in the process of connecting and replacing drill pipes in the prior art.

[0005] However, this tool still has the following problems. When the tool is used, it needs to be installed near the drilling equipment in advance, and then through the mutual cooperation between the mobile robotic arm and the steering mechanism, drive the drill pipe grasping device to move and turn. In the actual use process, in order to optimize the drilling effect, usually through advanced measurement equipment and technology, the drilling path or position is finely adjusted to ensure more accurate reaching the target reservoir. Therefore, the installation position of the tool may also need to be finely adjusted, and this tool lacks corresponding moving components, making it difficult to effectively improve the convenience of tool use.

[0024] Embodiment: As Figure 1 shown, a drill pipe connection replacement tool includes a base 1, wherein the base 1 is made of aluminum alloy material to improve the overall structural strength of the tool, and a driving device is installed inside the base 1. One side of the top of the base 1 is fixedly connected by welding with a fixed seat 2. A moving component is also provided below the base 1, and a clamping component is provided above the base 1.

[0025] As Figures 2 - 4As shown, in a certain embodiment, in order to improve the mobility of the tool, the moving component includes a pair of driving wheels 7 installed at one end of the base 1. One end of the driving wheel 7 is connected to a driving device installed inside the base 1. A pair of driven wheels 8 are installed at the other end of the base 1. Two groups of guide wheels 9 are installed on both sides of the outer wall of the base 1. A pair of crawler belts 10 are sleeved together between the driving wheel 7, the driven wheels 8 and the guide wheels 9 to form a transmission connection. The guide wheels 9 play a role in correcting the movement direction of the crawler belt 10. Two groups of piston rods 11 are slidably connected to the bottom of the base 1. The bottom end of each piston rod 11 is fixedly connected to a cantilever 12. A fixed shaft 13 is installed at one end of each cantilever 12. A load wheel 15 adapted to the crawler belt 10 is installed at one end of each fixed shaft 13. A spring 14 is sleeved between the outer peripheral wall of each piston rod 11 and the cantilever 12. Through the mutual cooperation among the piston rod 11, the cantilever 12 and the spring 14, it is convenient to buffer the bumps encountered during the movement of the tool and avoid affecting other components of the tool. A plurality of hydraulic telescopic rods 16 are fixedly connected to the bottom of the base 1 away from the piston rods 11. The extending end of each hydraulic telescopic rod 16 is fixedly connected to a support column 17. The bottom end of each support column 17 is fixedly connected to a support block 18. Each hydraulic telescopic rod 16 is inclined, and each support column 17 is perpendicular to the top of the base 1. Through the mutual cooperation among the hydraulic telescopic rod 16, the support column 17 and the support block 18, it is convenient to improve the stability of the tool during use.

[0026] As Figure 1 shown Figure 2 As shown, in a certain embodiment, in order to improve the efficiency of replacing the drill pipe of the tool, the clamping component includes a hydraulic folding arm 3 installed at one end of the fixed seat 2.

Then, through the mutual cooperation among the driving wheel 7, the driven wheel 8, the guide wheel 9, the load wheel 15, and the crawler 10, the tool is moved to the designated position. Through the mutual cooperation among the piston rod 11, the cantilever 12, and the spring 14, the bumps encountered during the movement of the tool are buffered to avoid affecting the normal use of other components of the tool, facilitating the cooperation with the continuously optimized drilling path and drilling position, effectively improving the convenience of tool use. Then, the hydraulic telescopic rod 16 is started, and the support column 17 and the support block 18 are driven to move through the hydraulic telescopic rod 16, so that the bottom of the support block 18 abuts against the ground, improving the stability of tool use. Then, the drill pipe is grasped through the mutual cooperation between the robotic arm 5 and the robotic claw 6. Then, the height and angle of the mounting seat 4 are changed through the hydraulic folding arm 3, so that the drill pipe moves to the designated position and angle, facilitating the improvement of the efficiency of drill pipe connection and replacement.
