Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, and in particular to a cable pushing and supporting device and a use method thereof, and a drilling and workover machine. Background Art

[0002] In the oil and gas extraction industry, well repair operations are a key link in ensuring the continued efficient production of oil wells. With the continuous development of oil exploration and extraction technology, the technical requirements for well repair operations are becoming increasingly higher. Well repair operations usually include complex salvage, repair of oil well casing, and casing inner drilling, etc. These operations require high-precision equipment and professional technical support.

[0003] In well repair operations, electric pumps are widely used. When the electric pump is lowered or lifted out, its supporting cable needs to move synchronously. In traditional operation methods, the movement of the cable mainly relies on manual operation. When the cable interferes with the pipe or other equipment, the operator needs to manually pull the cable apart to ensure that the pipe clamp or other shackle tools can operate smoothly. This operation method has the following main problems:

[0004] 1. High labor intensity: repeated manual operations require high physical strength from operators, and long-term work can easily lead to fatigue.

[0005] 2. Low operating efficiency: Manual operation is relatively inefficient and time-consuming, affecting the overall well repair progress.

[0006] 3. Poor safety: When handling cables, operators need to get close to dangerous areas such as wellheads, which increases safety risks.

[0007] 4. High cost: The cost of manual operation gradually increases over time, and low efficiency also leads to additional resource consumption.

[0008] In order to solve the above problems, the present invention proposes a cable lowering, raising and pushing mechanical arm device. The device can automatically complete the pushing and moving of the cable, reduce the necessity of manual operation, improve operation efficiency and safety, and reduce labor intensity and operation cost. The development and application of the device is an important embodiment of the progress of oil drilling and well repair technology, and is of great significance to improving the overall level of well repair operations.

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] Embodiment 1

[0050] In this embodiment, if Figure 1 , 2 As shown, a cable pushing and supporting device includes a manipulator 1 and a telescopic mechanism. The manipulator 1 is used to be arranged on a drilling platform 7 and can clamp a cable 8; the telescopic mechanism is arranged on the drilling platform 7 and can drive the manipulator 1 to approach or move away from a wellhead 5 of the drilling platform 7.

[0051] Furthermore, the manipulator 1 includes a manipulator arm 3 and a clamping device 6. The manipulator arm 3 is connected to the telescopic mechanism. One end of the manipulator arm 3 is rotatably connected to the drilling platform 7, and the other end is rotatably connected to the clamping device 6. The clamping device 6 is used to pass the cable 8.

[0052] The mechanical arm 3 is installed on the drilling platform 7 to ensure the stability of the mechanical arm 3. The cable 8 is connected to the electrical equipment 9 in the wellhead 5 after passing through the clamping device 6. By controlling the telescopic mechanism, the clamping device 6 can move freely in the horizontal direction, thereby realizing the pushing and lowering of the cable 8. The automatic pushing and moving of the cable 8 is realized, reducing manual operations and improving work efficiency. The setting of the mechanical arm 3 ensures that the cable 8 remains stable during the movement and avoids interference with surrounding equipment.

[0053] In addition, the installation positions of the mechanical arm 3 and the telescopic mechanism are not limited in the present disclosure. In some embodiments, the mechanical arm 3 and the telescopic mechanism can be directly connected to the drilling platform 7; in other embodiments, the mechanical arm 3 and the telescopic mechanism can be connected to the same base, and the base can be detachably connected to the drilling platform 7 to adjust the position of the base according to the position of the cable 8.

[0054] Furthermore, the robotic arm 3 is connected to the drilling platform 7 via the robotic arm pin 2, and the telescopic mechanism includes a telescopic cylinder 4, one end of which is rotatably connected to the drilling platform 7, and the other end of which is rotatably connected to the robotic arm 3, so as to drive the robotic arm 1 to rotate around the robotic arm pin 2.

[0055] The above arrangement ensures that one end of the mechanical arm 3 is rotatably connected to the drilling platform 7 through the mechanical arm pin 2 and other structures, one end of the telescopic cylinder 4 is rotatably connected to the drilling platform 7 through the pin, and the other end is rotatably connected to the middle of the mechanical arm 3 through the pin. The telescopic cylinder 4 of the mechanical arm 3 and the drilling platform 7 form a stable variable triangle, and a section of the mechanical arm 3 between the drilling platform 7 and the telescopic cylinder 4 is set as a telescopic structure. When the telescopic cylinder 4 is extended or shortened, it drives the mechanical arm 3 to move, thereby changing the horizontal position of the clamping device 6 relative to the wellhead 5, and realizing the pushing and lowering action of the cable 8.

[0056] The design of the telescopic oil cylinder 4 and the mechanical arm 3 ensures that the mechanical arm 3 remains stable during the telescopic process, enhancing the stability and reliability of the device. The rotatable connection of the mechanical arm 3 enables the mechanical arm 3 to flexibly adapt to the cable 8 operation requirements at different angles and positions.

[0057] The mechanical arm pin 2 is installed on the drilling platform 7 to ensure that the mechanical arm 3 is rotatably connected through the pin. When the telescopic oil cylinder 4 is in motion, the mechanical arm 3 rotates around the pin, thereby achieving the pushing and lowering of the cable 8.

[0058] The design of the mechanical arm pin 2 ensures that the mechanical arm 3 remains stable during the rotation process, and avoids the loosening or deviation of the cable 8 caused by the movement of the mechanical arm 3. The operating accuracy and efficiency of the mechanical arm 3 are improved, and the accuracy and stability of the movement of the cable 8 are ensured.

[0059] Furthermore, the clamping device 6 includes a front roller frame 61 and a rear roller frame 62, and a clamping space for clamping the cable 8 is formed between the front roller frame 61 and the rear roller frame 62. The front roller frame 61 and the rear roller frame 62 are rotatably connected to a plurality of guide rollers 64 that can abut against the cable 8.

[0060] The clamping device 6 is installed on the mechanical arm 3 to ensure that the roller front frame 61 and the roller rear frame 62 are movably connected through the pin shaft. When the cable 8 needs to be installed, the clamping device 6 is opened, the cable 8 is placed in the clamping device 6, and then the clamping device 6 is closed and the latch device 66 is locked.

[0061] The openable and lockable design of the clamping device 6 facilitates the installation and fixing of the cable 8, and improves the flexibility and efficiency of the operation. The arrangement of the pin and the latch device 66 ensures that the clamping device 6 can stably clamp the cable 8 after closing, and prevents the cable 8 from slipping out or loosening.

[0062] Guide rollers 64 are installed at corresponding positions at both ends of the roller front frame 61 and the roller rear frame 62 to ensure that the cable 8 can be stably clamped and guided when passing through the clamping device 6. In this embodiment, four guide rollers 64 are provided, which are respectively arranged at both ends of the roller front frame 61 and the roller rear frame 62 and correspond one to one.

[0063] The setting of the guide roller 64 ensures that the cable 8 remains stable when passing through the clamping device 6, and avoids the cable 8 from deflecting or loosening. The accuracy and efficiency of the operation of the cable 8 are improved, and the safety of the cable 8 during the movement is ensured.

[0064] Furthermore, the roller front frame 61 and the roller rear frame 62 are detachably connected.

[0065] Furthermore, it also includes a latch device 66, and the opposite sides of the roller front frame 61 and the roller rear frame 62 are detachably connected through the latch device 66;

[0066] By unlocking the latch device 66 on either side, the roller front frame 61 can rotate relative to the roller rear frame 62 around the latch device 66 on the other side, so that the clamping device 6 forms an opening for the cable 8 to enter.

[0067] Specifically, the latch device 66 includes a latch and a socket plate, and the socket plates are respectively arranged on both sides of the roller front frame 61 and the roller rear frame 62. The latch is used to insert the aligned socket plates of the roller front frame 61 and the roller rear frame 62. The latch is locked after insertion. When the roller front frame 61 and the roller rear frame 62 need to be opened, the latch device 66 on any side can be unlocked to rotate along the latch device 66 on the other side to open the clamping mechanism, which is convenient for punching the clamping mechanism from any angle under various working conditions, or opening the latch devices 66 on both sides at the same time to realize the disassembly of the clamping mechanism.

[0068] Furthermore, the roller rear frame 62 is rotatably connected to the mechanical arm 3 , and the roller front frame 61 is rotatably connected to a pipe-abutting roller 63 for abutting against the pipe entering and exiting the wellhead 5 .

[0069] The roller rear frame 62 is fixed on the robot arm 3 to ensure its stability. The pipe fixture abutting roller 63 is installed on the roller front frame 61 to ensure that the pipe fixture abutting roller 63 can maintain appropriate contact and distance with the pipe fixture when the robot arm 3 moves. When the pipe fixture abutting roller 63 contacts the surface of the pipe fixture when the pipe fixture moves, the pipe fixture abutting roller 63 can rotate under the drive of the pipe fixture, so as not to affect the movement of the pipe fixture.

[0070] The roller rear frame 62 is fixed on the robot arm 3 to ensure its stability. The pipe fixture abutting roller 63 is installed on the roller front frame 61 to ensure that the pipe fixture abutting roller 63 can maintain appropriate contact and distance with the pipe fixture when the robot arm 3 moves. When the pipe fixture abutting roller 63 contacts the surface of the pipe fixture when the pipe fixture moves, the pipe fixture abutting roller 63 can rotate under the drive of the pipe fixture, so as not to affect the movement of the pipe fixture.

[0071] Furthermore, a side guide wheel 65 is provided in the clamping device 6 in the direction in which the vertical cable 8 passes.

[0072] A side guide wheel 65 is installed in the clamping device 6 perpendicular to the direction in which the cables 8 pass, and is perpendicular to the guide roller 64, to ensure that the multiple cables 8 can be stably guided and supported during movement, and to prevent them from spreading to the gaps on both sides of the clamping device 6 and getting stuck.

[0073] The side guide wheels 65 ensure the stability of the cable 8 in the horizontal direction, and prevent the cable 8 from deflecting or loosening due to gravity or other factors, thereby improving the accuracy and efficiency of the operation of the cable 8 and ensuring the safety of the cable 8 in a complex operating environment.

[0074] Furthermore, a method for using the cable pushing device comprises the following steps:

[0075] S1: The electrical equipment 9 is connected to the cable 8;

[0076] S2: Open the front roller frame 61 and the rear roller frame 62, and adjust the position of the cable 8 to place the cable 8 between the guide rollers 64;

[0077] S3: closing the roller front frame 61 and the roller rear frame 62 and locking the latch device 66, so that the cable 8 can freely pass through the clamping device 6 and prevent it from slipping out;

[0078] S4: The cable 8 is passed around the guide pulley 10 on the top of the drilling platform 7 to connect the cable reel and the power supply end;

[0079] S5: When the electrical equipment 9 needs to be lowered or raised, the telescopic cylinder 4 is extended, so that the pipe of the clamping device 6 abuts against the roller 63 and the pipe of the wellhead 5;

[0080] S6: When performing other operations, the telescopic cylinder 4 is shortened, so that the clamping device 6 drives the cable 8 to move to the edge of the wellhead 5 to facilitate the operation.

[0081] Follow the above steps to ensure that each step is completed accurately. In actual operation, pay attention to the state and position of cable 8 to ensure that cable 8 remains stable and safe during the movement.

[0082] Clear operation steps ensure the smooth progress of the cable 8 lowering and lifting process, reduce the possibility of operational errors, improve work efficiency and safety, and ensure the standardization and standardization of cable 8 operations.

[0083] Furthermore, in a well drilling and repairing machine, a guide pulley 10 for passing the cable 8 is arranged on the top of the drilling platform 7.

[0084] A guide pulley 10 is installed on the top of the drilling platform 7 to ensure that the cable 8 can bypass the guide pulley 10 during movement and maintain the correct path and direction.

[0085] The setting of the guide pulley 10 ensures that the cable 8 maintains the correct path during the movement, avoids interference with surrounding equipment, improves the accuracy and efficiency of the cable 8 operation, and ensures the stability of the cable 8 during long-distance movement.
