Description

[0001] The present invention relates to the technical field of oil production equipment, and in particular to a lifting type well repair automation equipment and an operation method. Background Art

[0002] Lifting well repair automation equipment is an important equipment in the field of oil drilling and production. It aims to replace traditional manual operations through mechanization and intelligent means, significantly improving operational efficiency and reducing labor intensity. Among them, the foldable catwalk (transport track) is a widely used lifting equipment. The foldable catwalk solves the problems of traditional equipment transportation and well site installation.

[0003] When the foldable catwalk is in use, the oil pipe is first placed on the carrier frame, and then the lifting device lifts the carrier frame to the vicinity of the drilling platform. After that, the staff on the drilling platform uses the equipment to lift one end of the oil pipe and gradually moves the oil pipe from the carrier frame to the drilling platform. When the oil pipe is separated from the carrier frame, the lifting device lowers the carrier frame and places a new oil pipe on it for transportation. This method results in a window period for oil pipe installation during the process of lowering the carrier frame and lifting the new oil pipe. The equipment used to install the oil pipe is idle for a period of time, so there is still room for improvement in work efficiency. Summary of the Invention

[0014] An operating method of a lifting-type well repair automation equipment is based on the above-mentioned lifting-type well repair automation equipment, specifically comprising the following steps:

[0015] S1: First, the first lifting member is activated. The first lifting member lifts the carrier frame to the vicinity of the drilling platform. At this time, the carrier frame stops moving. Then, the first hydraulic rod is activated. The telescopic end of the first hydraulic rod extends and pushes the loading rack to rotate. When the loading rack rotates, the oil pipe is lifted until the oil pipe rolls along the loading rack to the transfer rack. Then, the loading rack and the first hydraulic rod are reset to prepare for transporting the next oil pipe.

[0016] S2: The servo motor drives the clamping rod to rotate until it clamps the oil pipe, and the second lifting part is activated to lift the transfer frame to the vicinity of the carrier frame, and the servo motor drives the clamping rod and the oil pipe are separated;

[0017] S3: Start the first reduction motor to rotate the transfer frame until the opening faces the carrier frame, so that the oil pipe rolls onto the carrier frame;

[0018] S4: When the oil pipe falls onto the carrier, it is blocked by the partition plate. When one oil pipe is installed, the telescopic end of the second hydraulic rod drives the partition plate downward. At this time, the oil pipe rolls toward the chain plate. At the same time, the telescopic end of the second hydraulic rod drives the partition plate upward. The transfer rack transports the new oil pipe to the carrier for standby use.

[0019] S5: The second reduction motor starts, and the output shaft of the second reduction motor drives the adjacent sprocket to rotate. The sprocket drives the chain plate to rotate. The chain plate transports the oil pipe toward the drilling platform and uses the blocking plate as an auxiliary to block the oil pipe.

[0020] S6: After use, the first lifting member and the second lifting member respectively drive the supporting frame and the transfer frame to return to their original positions.

[0021] The beneficial effects of the present invention are as follows: the present invention transports the oil pipe to the drilling platform by stopping the carrier near the drilling platform, and at the same time uses the transfer frame to transport the oil pipe from the ground to the carrier. During the period when the oil pipe is moved from the carrier to the drilling platform, the transfer frame transports the oil pipe from the ground to the carrier, thereby making full use of time. Compared with the carrier directly transporting the oil pipe back and forth, the time interval for installing the oil pipe is shorter.

[0022] The support frame is separated by a partition plate, so that two oil pipes can be placed on the support frame at the same time without affecting each other, further improving the continuity of the oil pipe installation and reducing the interval time of the oil pipe installation.

[0023] When the transfer rack is transporting the oil pipe, the clamping rod clamps the oil pipe, thereby reducing the probability of the oil pipe falling off when the transfer rack is transporting the oil pipe, and improving the safety of the transfer rack when transporting the oil pipe.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0034] This embodiment discloses a lifting type well repair automation equipment, which is used for continuously lifting oil pipes to reduce the time interval for oil pipe installation.

[0035] Please refer to Figure 1-Figure 5 , including a frame 1, the frame 1 is provided with a first lifting member 2 and a second lifting member 3, the frame 1, the first lifting member 2 and the second lifting member 3 are all existing devices for lifting the carrier 4 and the transfer frame 5, which will not be described in detail here. The first lifting member 2 is fixedly connected to the carrier 4, the carrier 4 is used to place the oil pipe and transport the oil pipe to the drilling platform, the second lifting member 3 is rotatably connected to the transfer frame 5, the transfer frame 5 is used to transport the oil pipe from the ground to the carrier 4, and the upper side of the carrier 4 is provided with a push rod portion 41 and an inclined portion 42, the push rod portion 41 is used to hold the oil pipe to be transported, and the inclined portion 42 is used to make the oil pipe roll toward the push rod portion 41, the second lifting member 3 is fixedly connected to the first The reduction motor 6 and the output shaft of the first reduction motor 6 are fixedly connected to the transfer frame 5. The first reduction motor 6 is used to drive the transfer frame 5 to rotate. The transfer frame 5 is higher than the supporting frame 4, so that when the transfer frame 5 rotates to the opening backward, the lower part of the transfer frame 5 is tilted toward the supporting frame 4, and the oil pipe can roll along the transfer frame 5 to the supporting frame 4. The front side of the frame 1 is rotatably connected to the loading rack 7 and the first hydraulic rod 8. The telescopic end of the first hydraulic rod 8 is rotatably connected to the loading rack 7. The loading rack 7 and the first hydraulic rod 8 are used to transfer the oil pipe from the oil pipe rack on the ground to the transfer rack 5. The oil pipe rack is an existing device, and the oil pipe on it can be moved to the top of the loading rack 7 for the loading rack 7 to be transferred.

[0036] Please refer to Figure 4 and Figure 6The carrier frame 4 is rotatably connected to the evenly distributed sprockets 9, and all the sprockets 9 are commonly provided with a chain plate 10. The sprocket 9 on the right is used to drive the chain plate 10 to rotate, and the remaining sprockets 9 are used to support the chain plate 10. A second reduction motor 11 is fixedly connected to the right side of the carrier frame 4, and the output shaft of the second reduction motor 11 is fixedly connected to the sprocket 9 on the right. The second reduction motor 11 drives the chain plate 10 to rotate, thereby assisting the oil pipe to move.

[0037] Please refer to Figure 4 and Figure 6 The chain plate 10 is fixed with two blocking plates 12, which are used to block the oil pipe. One blocking plate 12 is located on the upper right side of the chain plate 10, and the other blocking plate 12 (this blocking plate 12 is not shown in the figure) is located on the lower left side of the chain plate 10. The two blocking plates 12 are distributed symmetrically around the center. When the chain plate 10 rotates half a circle, the positions of the two blocking plates 12 are interchanged.

[0038] Working process: When using this device to transport equipment such as oil pipes, move this device to the vicinity of the drilling platform, place the arranged oil pipes near this device, and then start the first lifting member 2. The first lifting member 2 lifts the carrier frame 4 to the vicinity of the drilling platform. At this time, the carrier frame 4 no longer moves, and then start the first hydraulic rod 8. The telescopic end of the first hydraulic rod 8 extends and pushes the loading rack 7 to rotate. When the loading rack 7 rotates, the oil pipe is lifted until the oil pipe rolls along the loading rack 7 to the transfer rack 5. Then the first hydraulic rod 8 drives the loading rack 7 to reset, and at the same time the first reduction motor 6 is started and drives the transfer rack 5 to rotate. When the transfer rack 5 rotates to the front and rear sides and tilts up, the first reduction motor 6 stops working, and then the second lifting member 3 is started to lift the transfer rack 5 to the vicinity of the carrier frame 4. At this time Start the first reduction motor 6 again, rotate the transfer frame 5 to the rear side and tilt it toward the supporting frame 4, so that the oil pipe rolls onto the supporting frame 4, and then the oil pipe rolls from the inclined part 42 to the push rod part 41. The staff on the drilling platform lifts one end of the oil pipe. At this time, the second reduction motor 11 is started, and the output shaft of the second reduction motor 11 drives the adjacent sprocket 9 to rotate, and the sprocket 9 drives the chain plate 10 to rotate. The chain plate 10 transports the oil pipe toward the drilling platform and uses the upper side blocking plate 12 as an aid to block the oil pipe. Then, the oil pipe can be moved to the drilling platform. While moving the oil pipe, the second lifting member 3 and the first reduction motor 6 jointly drive the transfer frame 5 to reset, and then repeat the above-mentioned working steps of the transfer frame 5 to lift the next oil pipe, thereby reducing the interval time of lifting the oil pipe. Example 2

[0039] This embodiment discloses a lifting type well repair automation equipment. On the basis of the embodiment 1, the carrier 4 is capable of simultaneously loading two oil pipes without affecting each other, thereby further shortening the interval time of oil pipe installation.

[0040] Please refer to Figure 4 and Figure 6 The carrier frame 4 is slidably connected to a partition plate 13, which is used to separate the carrier frame 4 so that the carrier frame 4 can load two oil pipes at the same time without affecting each other. One oil pipe is installed and the other oil pipe is on standby. The carrier frame 4 is fixed with a second hydraulic rod 14. The fixed part of the second hydraulic rod 14 is embedded in the carrier frame 4. In the figure, only a part of the fixed part of the carrier frame 4 is exposed. The telescopic end of the second hydraulic rod 14 is fixed to the partition plate 13.

[0041] Please refer to Figure 5 The transfer rack 5 is fixed with a pad 15, the thickness of the pad 15 is equal to the radius difference of different parts of the oil pipe, and the pad 15 is used to keep the oil pipe in a horizontal state. The part with a larger diameter of the oil pipe contacts the transfer rack 5, and the part with a smaller diameter of the oil pipe contacts the pad 15.

[0042] Working process: When the oil pipe falls to the inclined portion 42, it is blocked by the partition plate 13, so that one oil pipe is in use, one oil pipe is on standby, and one oil pipe is transported, further shortening the interval time of oil pipe installation and improving work efficiency. When one oil pipe is installed, the second hydraulic rod 14 is started, and the telescopic end of the second hydraulic rod 14 is retracted and drives the partition plate 13 to move downward, so that the partition plate 13 releases the obstruction of the oil pipe. At this time, due to the inclination of the inclined portion 42, the oil pipe rolls toward the push rod portion 41. At the same time, the telescopic end of the second hydraulic rod 14 extends and drives the partition plate 13 to move upward and reset. The transfer rack 5 transports the new oil pipe to the inclined portion 42 for standby. Example 3

[0043] This embodiment discloses a lifting type well repair automation equipment. On the basis of the embodiment 1, the oil pipe is fixed when the transfer frame 5 transports the oil pipe.

[0044] Please refer to Figure 7 The transfer rack 5 is rotatably connected to a clamping rod 16, which is L-shaped to fix the oil pipe. The transfer rack 5 is fixed with a servo motor 17, and the clamping rod 16 is fixed with a toothless gear 18. The output shaft of the servo motor 17 is provided with a transmission gear 19, which meshes with the toothless gear 18. The servo motor 17 is used to drive the clamping rod 16 to rotate. When the transfer rack 5 transports the oil pipe, the servo motor 17 drives the clamping rod 16 to rotate until the oil pipe is clamped. When the oil pipe needs to be removed from the transfer rack 5, the servo motor 17 drives the clamping rod 16 to rotate to the initial position.

[0045] Working process: When the oil pipe is moved to the transfer rack 5, the servo motor 17 is started, and the output shaft of the servo motor 17 drives the clamping rod 16 to rotate through the transmission gear 19 and the toothless gear 18, so that the clamping rod 16 clamps the oil pipe, thereby reducing the probability of the oil pipe falling off during transportation. When the oil pipe needs to be moved from the transfer rack 5 to the supporting rack 4, the servo motor 17 drives the clamping rod 16 to return to its original position after the rotation of the transfer rack 5 is completed. At this time, the oil pipe can roll normally to the supporting rack 4. Example 4

[0046] This embodiment discloses a lifting type well repair automation equipment. On the basis of the embodiment 3, the clamping rod 16 is fixed to improve its stability when fixing the oil pipe.

[0047] Please refer to Figure 7 and Figure 8 The transfer frame 5 is fixed with a mounting rod 20, and the mounting rod 20 is L-shaped. The mounting rod 20 is slidably connected with a clamping block 21, which is composed of a U-shaped clamp and a straight rod. A spring is arranged between the clamping block 21 and the mounting rod 20. The spring is initially in a compressed state, which is used to make the clamping block 21 fit with the toothless gear 18, thereby clamping the toothless gear 18. The clamping block 21 is used to limit the toothless gear 18.

[0048] Please refer to Figure 7 and Figure 8 The mounting rod 20 is fixed with an electromagnet 22, and the straight rod portion of the clamping block 21 is inserted into the electromagnet 22. The clamping block 21 is made of a magnetic metal material, so that the electromagnet 22 can attract the clamping block 21 to move when it is energized.

[0049] Working process: before the servo motor 17 starts, the electromagnet 22 starts, the electromagnet 22 generates magnetic force and attracts the block 21 to move, and the block 21 compresses the adjacent spring, so that the block 21 releases the limit on the toothless gear 18, and then the servo motor 17 starts and drives the clamping rod 16 to rotate. When the servo motor 17 stops energizing, the electromagnet 22 also stops energizing, the magnetic force of the electromagnet 22 disappears, and the block 21 is reset under the action of the adjacent spring, thereby jamming the toothless gear 18, making the toothless gear 18 and the clamping rod 16 unable to rotate, thereby improving the stability of the clamping rod 16 when fixing the oil pipe. Example 5

[0050] Please refer to Figures 1-8 An operating method of a lifting well workover automation device is provided, based on the above-mentioned lifting well workover automation device, and specifically comprises the following steps:

[0051] S1: First, the first lifting member 2 is activated. The first lifting member 2 lifts the carrier 4 to the vicinity of the drilling platform. At this time, the carrier 4 stops moving. Then, the first hydraulic rod 8 is activated. The telescopic end of the first hydraulic rod 8 extends and pushes the loading rack 7 to rotate. When the loading rack 7 rotates, the oil pipe is lifted until the oil pipe rolls along the loading rack 7 to the transfer rack 5. Then, the loading rack 7 and the first hydraulic rod 8 are reset to prepare for transporting the next oil pipe.

[0052] S2: The servo motor 17 drives the clamping rod 16 to rotate until the oil pipe is clamped, and the second lifting member 3 is activated to lift the transfer frame 5 to the vicinity of the supporting frame 4. The servo motor 17 drives the clamping rod 16 to separate from the oil pipe;

[0053] S3: Start the first reduction motor 6 to rotate the transfer frame 5 until the opening faces the carrier frame 4, so that the oil pipe rolls onto the carrier frame 4;

[0054] S4: When the oil pipe falls onto the carrier 4, it is blocked by the partition plate 13. When one oil pipe is installed, the telescopic end of the second hydraulic rod 14 drives the partition plate 13 downward. At this time, the oil pipe rolls toward the chain plate 10. At the same time, the telescopic end of the second hydraulic rod 14 drives the partition plate 13 upward. The transfer rack 5 transports the new oil pipe to the carrier 4 for standby use.

[0055] S5: The second reduction motor 11 is started, and the output shaft of the second reduction motor 11 drives the adjacent sprocket 9 to rotate. The sprocket 9 drives the chain plate 10 to rotate. The chain plate 10 transports the oil pipe toward the drilling platform and blocks the oil pipe with the aid of the blocking plate 12.

[0056] S6: After use, the first lifting member 2 and the second lifting member 3 respectively drive the supporting frame 4 and the transfer frame 5 to return to their original positions.
