Description

Technical Field

[0001] The invention relates to a high-position disassembly and assembly device and a disassembly and assembly method for a two-layer platform automatic pipe arrangement manipulator, belonging to the technical field of oil and natural gas drilling and production. Background Art

[0002] In oil and gas drilling and production operations, the application of automated second-floor platform pipe laying technology has become a trend. More and more pipe laying manipulators are used to replace manual operations of second-floor platform pipe laying work. The application of pipe laying manipulators not only reduces the labor intensity of operators and improves the working environment, but also greatly reduces the operating risks of pipe laying workers. With the increase in the number of pipe laying manipulators used and the use time of manipulator equipment, the number of installation and disassembly of pipe laying manipulators has also greatly increased, and maintenance has become more frequent, especially the frequency of overhauls. Moreover, when the manipulator is overhauled, the manipulator must be separated from the second-floor platform and moved to the drilling platform or overhaul plant for overhaul and maintenance. Since the second-floor platform is installed at an altitude of more than 20 meters, the process of disassembling the manipulator is very inconvenient, and the installation process of the manipulator after overhaul and maintenance is also very difficult, and the operation risk coefficient is very high.

[0003] In order to reduce the risk factor of operation, when dismantling or installing the pipe-laying manipulator, the second-layer platform and the pipe-laying manipulator are assembled into one at a low position, and then the second-layer platform and the pipe-laying manipulator are dismantled and assembled with the derrick together by a large crane, or the derrick is knocked down and dismantled at a low position; however, due to the heavy weight and large volume of the second-layer platform, and the pipe-laying manipulator installed on it, the dismantling and assembly process is very cumbersome. This dismantling and assembly method is not only difficult to operate, but also prone to safety accidents and extremely high operating costs. At the same time, it is also accompanied by great operational risks and the hidden dangers of safety accidents; moreover, drilling operations are generally carried out in the wilderness with limited traffic conditions. It is difficult for large cranes to enter in some areas, which also limits the use of large cranes to dock and dismantle the second-layer platform and the pipe-laying manipulator with the derrick as a whole.

[0004] There are no large cranes available on offshore drilling platforms, and there are few platform cranes on offshore platforms that can cover the entire second-floor installation area. Platform cranes do not meet the requirements of installing the second-floor platform, so the rigs and second-floor platforms of offshore platforms are all disassembled and assembled using large floating cranes. However, the use of large floating cranes also has its drawbacks. First, the number of large floating cranes is limited. Generally, renting a large floating crane requires a waiting period of about 6 months in advance, and the pipe-laying manipulator for maintenance cannot accept such a long waiting period. Second, the cost of renting a large floating crane is very expensive, and the starting price of renting a large floating crane is more than RMB 1 million. The pipe-laying manipulator for maintenance cannot afford such a high cost. Third, the use of large floating cranes also needs to consider seasonality. It is not appropriate to use large floating cranes for operations in typhoon-intensive seasons, and there are operational risks. In addition, it is impossible to knock down the derrick when repairing the pipe-laying manipulator of the offshore drilling platform drilling rig. Therefore, it is necessary to design a high-position disassembly and assembly device and disassembly and assembly method for the automatic pipe-laying manipulator of the second-floor platform, which does not need to disassemble and assemble the second-floor platform, but only needs to use the drilling rig lifting system to disassemble and assemble the second-floor platform at a high position. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art and to provide a method for disassembling and assembling a pipe-laying manipulator, which does not require disassembling and assembling the second-layer platform. It only needs to use the drilling rig lifting system to disassemble and assemble the pipe-laying manipulator at a high position separately. The disassembly and assembly process is simple, the operation is safe and reliable, and the disassembly and assembly cost of the pipe-laying manipulator is greatly reduced; to solve the problem that the existing pipe-laying manipulator must be disassembled and assembled as a whole with the second-layer platform when disassembling and assembling. Due to the heavy weight and large volume of the second-layer platform and the pipe-laying manipulator installed on it, the disassembly and assembly process is very cumbersome, the operation is difficult, the operation cost is high, and there are also problems such as potential safety accidents.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] A high-position disassembly and assembly device for an automatic pipe-laying manipulator on a two-layer platform, comprising a high-position mounting frame, a bearing guide rail and a traction rope, one end of the traction rope is fixed on the pipe-laying manipulator, and the other end is movably placed on the two-layer platform body; the bearing guide rail is a long strip structure similar to a rectangle, and its cross-sectional structure is a C-shaped groove cavity, and bolt mounting holes are processed on the long strip structure, and the bearing guide rail is symmetrically mounted on the guide rail mounting seats on both sides of the monkey platform; the high-position mounting frame is symmetrically mounted on the inner side of the monkey platform, and a concave groove is made in the middle part of the large end of the open hole vertical plate of the high-position mounting frame, a guide transition block is fixed on one side of the concave groove, and a pad and an adjustment plate are fixed on the other side of the concave groove, after the open hole vertical plate is clamped into the end of the guide rail mounting seat through the guide transition block, the pad and the adjustment plate are used to adjust the installation angle of the open hole vertical plate, and then it is locked and fixed to the monkey platform by the mounting bolts.

[0008] A load-bearing plate is welded to one side of the perforated vertical plate of the high-position mounting frame to form an L-shaped load-bearing bracket, and reinforcing ribs are welded below the load-bearing plate; rectangular mounting bolt holes are processed on the large end of the perforated vertical plate, and the hole spacing and size are consistent with the mounting holes on the monkey platform; a handle is welded to the outside of the perforated vertical plate.

[0009] A single-sided slotted C-shaped rectangular cavity is made on the inner side of one end of the guide transition block. The cross-sectional dimensions of the guide transition block are completely consistent with the cross-sectional dimensions of the bearing guide rail. The other end of the guide transition block is made with a three-sided conical chamfer for guiding. The chamfer angle is 20° to 30°, and the length of the guide chamfer surface is 50 to 80 mm.

[0010] Two adjusting bolt holes are formed on the adjusting plate, and an empty slot for adjusting the installation angle is formed between the adjusting plate and the backing plate.

[0011] A disassembly and assembly method of a high-position disassembly and assembly device of a two-layer platform automatic pipe arrangement manipulator

[0012] Step 1: Install the high-position mounting brackets on the left and right sides;

[0013] Remove the monkey platform sealing plate at the end of the monkey platform, symmetrically install the two bearing guide rails on the guide rail mounting seats on both sides of the monkey platform, and then insert the two high-position mounting frames into the ends of the guide rail mounting seats through the guide transition blocks, and symmetrically install them on the inner side of the monkey platform; when installing the high-position mounting frame, the high-position mounting frame should be vertically flattened, the guide transition block of the high-position mounting frame should be aligned with the belly plate of the monkey platform, and the high-position mounting frame should be inserted along the direction of the guide rail mounting seat, so that the mounting bolt holes on the high-position mounting frame are aligned with the bolt mounting holes at the end of the monkey platform, and at the same time, the outer surface of the end of the guide rail mounting seat should be closely matched with the inner cavity surface of the guide transition block;

[0014] Step 2: Adjust the installation angle of the high-position mounting bracket;

[0015] The installation angle of the high-position mounting frame is adjusted by the pad and the adjustment plate. Before tightening the mounting bolts, the mounting angle of the high-position mounting frame at the end of the monkey platform is adjusted by rotating the adjustment bolts forward and backward through the adjustment bolt holes on the adjustment plate of the high-position mounting frame to ensure the tightness of the connection between the bearing guide rail and the guide transition block, so as to ensure the consistency of the bearing plate height and left-right spacing of the high-position mounting frame on the left and right sides of the monkey platform. After the adjustment is completed, the monkey platform, the bearing guide rail and the high-position mounting frame are connected into a whole by the mounting bolts.

[0016] Step 3: Hoist the pipe laying manipulator onto the high-position mounting frame;

[0017] After the high-position installation frame is installed, the derrick hoisting system on the derrick and the pre-installed hoisting rope are used to lift the pipe laying manipulator to the front upper part of the high-position installation frame, and then the derrick hoisting system is slowly lowered. At the same time, the traction rope pre-installed on the upper part of the pipe laying manipulator is used to pull the pipe laying manipulator toward the monkey platform, so that the pipe laying manipulator is placed on the high-position installation frame;

[0018] Step 4: Pull the pipe laying manipulator into the monkey platform;

[0019] After the pipe laying manipulator is placed on the high-position mounting frame, the pipe laying manipulator is continuously pulled toward the monkey platform through the traction rope, so that a part of the moving trolley of the pipe laying manipulator enters the monkey platform, and then the lifting rope on the pipe laying manipulator is removed. After the lifting rope is removed, the traction rope is used again to completely drag the pipe laying manipulator onto the bearing guide rail in the monkey platform to complete the installation of the pipe laying manipulator;

[0020] Step 5: Remove the high-position mounting frame and install the monkey platform cover plate;

[0021] After the pipe laying manipulator is installed, the two high-position mounting frames are removed and the monkey platform sealing plate is installed and restored to prevent the pipe laying manipulator from derailing during work. The high-position installation of the entire second-level platform automatic pipe laying manipulator is completed;

[0022] If the pipe laying manipulator needs to be overhauled and maintained, the pipe laying manipulator on the second-floor platform needs to be removed from a high position. The pipe laying manipulator can be removed by reversing the above steps and then lowered to the drilling table for overhaul.

[0023] The beneficial effects of the present invention compared with the prior art are:

[0024] The high-position disassembly and assembly device and disassembly and assembly method of the second-layer platform automatic pipe-laying manipulator do not require disassembly and assembly of the second-layer platform, but utilize the lifting system of the drilling rig itself to directly disassemble and assemble the pipe-laying manipulator on the second-layer platform through the high-position mounting frame; and can guide and fine-tune the up, down, left and right directions through the guide transition block on the high-position mounting frame, thereby ensuring the convenience and safety of the high-position installation of the pipe-laying manipulator; and solve the problem that the existing second-layer platform and the pipe-laying manipulator are disassembled and assembled in an integrated manner, which is heavy and bulky, resulting in a cumbersome installation process, not only difficult to operate, but also high in operating cost, and accompanied by potential safety accidents;

[0025] The high-position disassembly and assembly device and disassembly and assembly method of the two-layer platform automatic pipe-laying manipulator can prevent the manipulator from running safely and not falling off the guide rail through the monkey platform sealing plate of the monkey platform port; since there is no need to disassemble and assemble the two-layer platform, it not only reduces the labor intensity of the operators and greatly improves the work efficiency, but also greatly reduces the risk of disassembly and assembly operations of the pipe-laying manipulator, which has positive significance for safe production; in addition, the present invention utilizes the drilling rig lifting system as the installation power source, which not only does not require the increase of the use fee of additional lifting equipment, but also does not require waiting for the use cycle of the lifting equipment. As long as the drilling rig equipment lifting system can work normally, the pipe-laying manipulator can perform high-position installation operations, which greatly reduces the operating cost.

A load-bearing plate 10 is welded to one side of the perforated vertical plate 9 to form an L-shaped load-bearing bracket, and a reinforcing rib 11 is welded below the load-bearing plate 10; rectangular mounting bolt holes are processed on the large end of the perforated vertical plate 9, and the hole spacing and size are consistent with the mounting holes on the monkey platform 2; a handle 15 is welded to the outside of the perforated vertical plate 9 to facilitate the operation of the operator during installation.

[0037] After the perforated vertical plate 9 is inserted into the end of the bearing guide rail 3 through the guide transition block 12, the installation angle of the perforated vertical plate 9 is adjusted by the pad 13 and the adjustment plate 14, and then it is locked and fixed with the bearing guide rail 3 by the installation bolts 17. A C-shaped rectangular cavity with a single-sided groove is made on the inner side of one end of the guide transition block 12, and the cross-sectional dimensions of the guide transition block 12 are completely consistent with the cross-sectional dimensions of the bearing guide rail 3. The other end of the guide transition block 12 is made with a three-sided conical chamfer for guiding, the chamfer angle is 20° to 30°, and the length of the guide chamfer surface is 50 to 80 mm.

[0038] The specific disassembly and assembly method of the high-position disassembly and assembly device of the second-layer platform automatic pipe arrangement robot is as follows, taking the installation of the automatic pipe arrangement robot at the high position of the second-layer platform as an example.

[0039] Step 1: Install the high-position mounting brackets 4 on the left and right sides;

[0040] Remove the monkey platform sealing plate 21 at the end of the monkey platform 2, symmetrically install the two bearing guide rails 3 on the guide rail mounting seats 16 on both sides of the monkey platform 2, and then insert the two high-position mounting frames 4 into the ends of the guide rail mounting seats 16 through the guide transition blocks 12, and symmetrically install them on the inner side of the monkey platform 2; when installing the high-position mounting frame 4, the high-position mounting frame 4 should be vertically leveled, the guide transition blocks 12 of the high-position mounting frame 4 should be aligned with the web of the monkey platform 2, and the high-position mounting frame 4 should be inserted along the direction of the guide rail mounting seat 16, so that the 4 mounting bolt holes on the high-position mounting frame 4 are aligned with the 4 bolt mounting holes at the end of the monkey platform 2, and at the same time, the outer surface of the end of the guide rail mounting seat 16 is tightly matched with the inner cavity surface of the guide transition block 12;

[0041] Step 2: Adjust the installation angle of the high-position mounting bracket 4;

[0042] The installation angle of the high-position mounting frame 4 is adjusted by the pad 13 and the adjustment plate 14. Before tightening the four mounting bolts 17, the installation angle of the high-position mounting frame 4 at the end of the monkey platform 2 is adjusted by rotating the adjusting bolt 18 forward and reversely through the adjusting bolt hole on the adjustment plate 14 of the high-position mounting frame 4 to ensure the tightness of the connection between the bearing guide rail 3 and the guide transition block 12 so that they form a seamless connection. At the same time, the consistency of the height and left-right spacing of the bearing plate 10 of the high-position mounting frame 4 on the left and right sides of the monkey platform 2 can also be ensured, so that the safety of the high-position installation of the manipulator is improved; after the adjustment bolt 18 is adjusted, the monkey platform 2, the bearing guide rail 3 and the high-position mounting frame 4 are locked and connected into a whole by four mounting bolts 17 to ensure that the high-position mounting frame 4 is firm and reliable, so that the safety of the high-position installation of the pipe laying manipulator 6 is further improved.

[0043] Step 3: hoist the pipe laying manipulator 6 onto the high-position mounting frame 4;

[0044] After the high-position mounting frame 4 is installed, the derrick hoisting system 7 on the derrick and the four pre-installed hoisting ropes 8 are used to hoist the pipe laying manipulator 6 to the front upper part of the high-position mounting frame 4, and then the derrick hoisting system 7 is slowly lowered. At the same time, the traction rope 5 pre-installed on the upper part of the pipe laying manipulator 6 is used to pull the pipe laying manipulator 6 toward the monkey platform 2, so that the lower side rollers on the moving trolley 19 of the pipe laying manipulator 6 are placed on the bearing plate 10 on the high-position mounting frame 4 (as shown in the attached figure). Figure 6 shown);

[0045] Step 4: Draw the pipe arrangement manipulator 6 into the monkey platform 2;

[0046] After the pipe laying manipulator 6 is placed on the high-position mounting frame 4 and stabilized, the pipe laying manipulator 6 is continuously pulled toward the monkey platform 2 by the traction rope 5, so that a part of the moving trolley 19 of the pipe laying manipulator 6 enters the monkey platform 2. In the process of the pipe laying manipulator 6 moving along the monkey platform 2, the tapered chamfer at the tail end of the guide transition block 12 enters the groove channel formed by the upper roller 20 of the moving trolley 19 of the pipe laying manipulator 6. When the groove channel contacts the tail end of the guide transition block 12, the tapered chamfer at the tail end of the guide transition block 12 simultaneously guides and fine-tunes the roller 20 in the up-down and left-right directions, so that It accurately enters the guide transition block 12; the tapered guide angle at the rear end of the guide transition block 12 can also help the roller 20 on the moving trolley 19 of the pipe laying manipulator 6 to smoothly enter the guide transition block 12; as the pipe laying manipulator 6 continues to move, the roller 20 on the moving trolley 19 of the pipe laying manipulator 6 will also be guided onto the bearing guide rail 3. At this time, the moving trolley 19 of the pipe laying manipulator 6 should be allowed to enter the monkey platform 2 as much as possible until the position of the lifting rope 8 is stopped without affecting the removal, and then the four lifting ropes 8 on the pipe laying manipulator 6 are removed, and the derrick lifting system 7 (as shown in the attached Figure 7 As shown); after the lifting rope 8 is disassembled, the traction rope 5 is used again to pull the pipe laying manipulator 6 toward the monkey platform so that it is completely dragged onto the bearing guide rail 3 to complete the installation of the pipe laying manipulator 6.

[0047] Step 5: Remove the high-position mounting frame 4 and install the monkey platform cover plate;

[0048] After the pipe laying manipulator 6 is installed, the two perforated vertical plates 9 of the high-position mounting frame 4 are removed, and the monkey platform sealing plate 21 is installed and restored to prevent the pipe laying manipulator 6 from derailing during work. The high-position installation of the entire second-layer platform automatic pipe laying manipulator is completed. Figure 8 as shown).

[0049] If the pipe laying manipulator 6 needs to be overhauled and maintained, the pipe laying manipulator 6 on the second-floor platform needs to be removed from a high position. The pipe laying manipulator 6 can be removed by reversely operating the above steps and then lowered to the drilling table for overhaul.

[0050] The present invention disassembles and assembles the pipe-laying manipulator 6 through the high-position mounting frame 4, and guides and fine-tunes the pipe-laying manipulator 6 through the guide transition block 12 on the high-position mounting frame 4; the convenience and safety of high-position disassembly and assembly of the pipe-laying manipulator 6 are ensured; the existing problem of using an integrated disassembly and assembly process of the second-layer platform body 1 and the pipe-laying manipulator 6 is solved, which makes the disassembly and assembly process complicated due to its heavy weight and large volume, and not only is the operation difficult and the operation cost high, but also is accompanied by the potential safety accident hazards; the use of the present invention not only reduces the labor intensity of the operators, but also greatly reduces the operation risk of the pipe-laying workers, and has a very positive significance for the disassembly and assembly of the pipe-laying manipulator of the drilling high-position mounting frame, especially the disassembly and assembly of the pipe-laying manipulator of the offshore drilling high-position mounting frame, and safe production.
