Description

Technical Field

[0001] The utility model relates to the technical field of offshore operations, in particular to a rotatable drilling rig slide rail system. Background Art

[0002] When operating at sea, usually two independent offshore structures need to share a drilling module, and the drilling module to be used needs to slide back and forth between the tracks installed on the two independent offshore structures through the slide rails between the two independent offshore structures.

[0003] For two independent offshore structures, due to their stiffness differences, there will be relative displacements in the up and down directions and in the lateral directions, and the floating frequencies will also be different.

[0004] For two independent offshore structures in shallow water, due to their small height, the difference in lateral stiffness will not be obvious. Therefore, a fixed sliding rail is used to connect the two independent offshore structures, and their different frequency displacements can absorb the difference in displacement through the structural truss.

[0005] For two independent offshore structures in medium-deep water (e.g., about 100 meters or more), due to their high height, the difference in their lateral stiffness will cause different natural frequencies. Under strong wind, wave and current conditions, there is a large relative displacement between the two, and they are often not in the same frequency range. Therefore, if they are rigidly connected by fixed slide rails, it is easy to cause damage to the fixed slide rail connection structure. As a prior art, no better design solution has been invented to solve the relevant technical problems.

[0006] In this regard, the inventor of this patent combined his work experience, conducted in-depth thinking on the problems encountered in the work, read a large amount of scientific research materials and literature, and gradually conceived and designed this application through retrieval and novelty search.

[0068] The rotatable drilling rig slide rail system 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0069] Reference Figure 1 to Figure 2 As shown, the rotatable drilling rig slide rail system 1000 provided according to the embodiment of the utility model is used to connect the fixed slide rail A3000 installed on the offshore independent structure A2000 and the fixed slide rail B5000 installed on the offshore independent structure B4000, including a floating slide rail 10, a lifting device 20 for controlling the up and down movement of the floating slide rail 10, and a support frame 30 for supporting the lifting device 20;

[0070] The floating rail 10 is disposed between the fixed rail A3000 and the fixed rail B5000, with its left end being connected to the fixed rail A3000 and its right end being connected to the fixed rail B5000;

[0071] Furthermore, the lifting device 20 is arranged between the lower bottom surface of the floating slide rail 10 and the upper end surface of the support frame 30; the support frame 30 is fixedly mounted on the offshore independent structure A2000;

[0072] Under the control of the lifting device 20, the floating slide rail 10 can move up and down until it is flush with the fixed slide rail A3000 and / or the fixed slide rail B5000.

[0073] Based on the above, it can be clearly seen that when the present application is implemented specifically, it is mainly used as a rotatable drilling rig slide rail system 1000.

[0074] Specifically, when applying the present application, the present application is assembled in the above manner, and when the wind and waves at sea are relatively calm, so that the fixed slide rail A3000 and the fixed slide rail B5000 are on the same horizontal line or close to being on the same horizontal line, the lifting device 20 can be started to drive the floating slide rail 10 to move up and down until it is flush with the fixed slide rail A3000 and / or the fixed slide rail B5000. In this way, the drilling rig module described in the background technology can be transferred from the fixed slide rail A3000 to the fixed slide rail B5000 through the floating slide rail 10, or from the fixed slide rail B5000 to the fixed slide rail A3000 through the floating slide rail 10.

[0075] The use of the above-mentioned application will obviously have the following technical effects:

[0076] On the one hand, the floating slide rail 10 plays a role of transition, and its upper and lower heights are adjustable, so that during use, it can be raised to be flush with the fixed slide rail A3000 and / or the fixed slide rail B5000 at any time, so that the drilling rig module described in the background technology can be transferred from the fixed slide rail A3000 to the fixed slide rail B5000 through the floating slide rail 10 flush with it, or from the fixed slide rail B5000 to the fixed slide rail A3000 through the floating slide rail 10 flush with it, making the present application convenient to use and flexible and reliable.

[0077] On the other hand, during the use of the above-mentioned present application, the left end of the floating slide rail 10 is only connected to the right end of the fixed slide rail A3000 but not directly connected and fixed thereto, and the right end is only connected to the left end of the fixed slide rail B5000 but not directly connected and fixed thereto, so that it is not a rigid connection and is not easy to cause relative displacement at the connection under conditions such as wind, waves and currents, thereby causing damage to the structure of the connection. In other words, the present application can effectively avoid related problems during actual use and prolong its service life.

[0078] Furthermore, in the technical solution of the present application, the support frame 30 is connected and fixed to the offshore independent structure A2000 via the fixed shaft 50, so that the floating slide rail 10 supported thereon is not easily displaced, on the basis of being not easily displaced.

[0079] Furthermore, by performing the above-mentioned optimized design, the overall structure of the present application is made to have strong practicality and good use effect.

[0080] Furthermore, in a specific implementation, according to an embodiment of the present utility model, a plurality of lifting devices 20 are provided and are evenly arranged between the lower bottom surface of the floating slide rail 10 and the upper end surface of the support frame 30 .

[0081] Therefore, by evenly arranging a plurality of lifting devices 20 to support the floating slide rail 10, the floating slide rail 10 is supported with uniform force, and has good support stability and is not prone to circumferential shaking.

[0082] Preferably, in the present technical solution, the lifting device 20 is preferably a lifting cylinder, a screw-driven linear module or a cylinder-driven linear module, etc.

[0083] Furthermore, in a specific implementation, according to an embodiment of the utility model, the present application further includes a fixed sleeve 40, a fixed shaft 50 and an auxiliary lifting device 60;

[0084] The fixed sleeve 40 is fixed on the offshore independent structure A2000 in the vertical direction; the upper end of the fixed shaft 50 is sleeved in the fixed sleeve 40; the left end of the support frame 30 extends to the bottom of the offshore independent structure A2000, and a sleeve hole A (not marked) is opened in the left middle part thereof, which penetrates the upper and lower end surfaces thereof and is fixed to the outside of the fixed shaft 50;

[0085] In addition, the auxiliary lifting device 60 is fixedly mounted on the upper left end surface of the support frame 30, and its top is against the bottom of the offshore independent structure A2000.

[0086] In this regard, it is clear that:

[0087] On the one hand, since the fixed shaft sleeve 40 is vertically fixed on the independent offshore structure A2000; the upper end of the fixed shaft 50 is sleeved in the fixed shaft sleeve 40; the left end of the support frame 30 extends to the bottom of the independent offshore structure A2000, and a sleeve hole A (not marked) is provided in the left middle part thereof, which passes through the upper and lower end surfaces and is adapted to be fixed to the outside of the fixed shaft 50. Therefore, the support frame 30 can rotate around the fixed shaft 50, so that the position of the floating slide rail 10 supported thereon in the lateral direction can be adjusted, making it more flexible to use.

[0088] On the other hand, since the present application also includes the auxiliary lifting device 60, the auxiliary lifting device 60 is fixed on the upper left end surface of the support frame 30, and its top is against the bottom of the offshore independent structure A2000. Therefore, when using the present application, the floating slide rail 10 will generate downward pressure on the right part of the support frame 30, so that the left part of the support frame 30 will be tilted up and generate a force on the fixed shaft 50 to the lower right. By controlling the auxiliary lifting device 60 to rise and fall to a suitable height so that its top is against the bottom of the offshore independent structure A2000, at this time, the bottom of the offshore independent structure A2000 will generate a downward force on the whole formed by the auxiliary lifting device 60 and the left part of the support frame 30. In this way, the stability of the left and right ends of the support frame 30 can be better controlled, so that it can support the floating slide rail 10 more stably. At the same time, it can also weaken the force generated by it on the fixed shaft 50 to the lower right, so that the service life of the fixed shaft 50 is long.

[0089] Furthermore, by performing the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0090] Preferably, in the present technical solution, the auxiliary lifting device 60 is also preferably a lifting cylinder, a screw-driven linear module or a cylinder-driven linear module, etc.

[0091] In addition, in the specific implementation, the control Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the present application also includes a push-pull device for pushing and pulling the support frame 30 so as to rotate it around the fixed axis 50 between the first position and the second position;

[0092] Wherein, the push-pull device is fixed on the offshore independent structure A2000 and connected to the support frame 30;

[0093] Reference Figure 3 As shown, when the push-pull device controls the support frame 30 to rotate to the first position, the floating rail 10 thereon is located between the fixed rail A3000 and the fixed rail B5000; Figure 4 As shown, when the push-pull device controls the support frame 30 to rotate to the second position, the floating slide rail 10 thereon deviates from the fixed slide rail B5000.

[0094] In this regard, it can be clearly seen that the present application, by providing the push-pull device, can control the support frame 30 and the floating slide rail 10 supported thereon to rotate between the first position and the second position. While being able to adjust the lateral position of the floating slide rail 10, when the present application is not in use, the push-pull device can be used to control the support frame 30 to rotate to the second position so that the floating slide rail 10 supported thereon deviates from the fixed slide rail B5000. In this way, there is basically no object between the offshore independent structure A2000 and the offshore independent structure B4000, so that they do not affect each other when different displacements occur, and the floating slide rail 10 is not easily hit by the offshore independent structure A2000 and the offshore independent structure B4000 when they are displaced when not in use.

[0095] Furthermore, by performing the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0096] Furthermore, in the specific implementation, continue to compare Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the push-pull device includes a multi-axis manipulator 701 and a driving device 702 for controlling the multi-axis manipulator 701 to extend / retract and correspondingly drive the support frame 30 to rotate to the first position and drive the support frame 30 to rotate to the second position;

[0097] The driving device 702 is fixed on the offshore independent structure A2000 , and the multi-axis manipulator 701 is connected between the driving device 702 and the support frame 30 .

[0098] Therefore, by setting the multi-axis manipulator 701 to pull the support frame 30, it and the driving device 702 together constitute the push-pull device. When its movement stroke is long enough, it can also facilitate flexible control of the support frame 30 to rotate around the fixed axis 50.

[0099] It should be noted here that when the multi-axis manipulator 701 and the driving device 702 together constitute the push-pull device, its use principle is basically the same as the use principle of the traditional excavator and other working equipment with a multi-axis manipulator 701. It can be directly purchased and installed in the existing market, so its specific details of the structure, etc., will not be described in detail here.

[0100] Again, in the specific implementation, Figure 1 and Figure 2 As shown, according to one embodiment of the utility model, the present application further includes an auxiliary fixing frame 80 and an auxiliary connecting rib 90;

[0101] Among them, the auxiliary fixing frame 80 is arranged at the bottom of the support frame 30 and is connected to the support frame 30 through the auxiliary connecting rib 90, and the left end of the auxiliary fixing frame 80 is provided with a sleeve hole B (not marked) that passes through its upper and lower end surfaces and is fixed to the outside of the fixed shaft 50.

[0102] Preferably, in the technical solution, according to an embodiment of the utility model, a plurality of auxiliary connecting ribs 90 are provided and are evenly fixed between the support frame 30 and the auxiliary fixing frame 80 .

[0103] In this regard, it is clear that:

[0104] On the one hand, by providing the auxiliary fixing frame 80 and the auxiliary connecting rib 90, and connecting the auxiliary fixing frame 80 to the support frame 30 through the auxiliary connecting rib 90, and providing the left end of the auxiliary fixing frame 80 with an adaptor hole B (not shown) penetrating through the upper and lower end surfaces thereof and fixed to the outside of the fixed shaft 50, the support frame 30 can be supported to improve the stability of the support frame 30 and the stability of the floating slide rail 10 being supported.

[0105] On the other hand, when a plurality of the auxiliary connecting ribs 90 are provided to connect the support frame 30 and the auxiliary fixing frame 80, the overall weight can be reduced, so that it is not easy to generate a large load on the offshore independent structure A2000.

[0106] It should be added that, in the specific implementation, continue to compare Figure 1 and Figure 2 As shown, according to one embodiment of the utility model, the present application further includes a plurality of connecting rods 100;

[0107] The left ends of the plurality of connecting rods 100 are all connected to the offshore independent structure A2000 , and the right ends are all connected to the fixed shaft 50 .

[0108] Therefore, by providing a plurality of the connecting rods 100 to fix the fixed shaft 50 , both upper and lower ends of the fixed shaft 50 can be fixed stably, making it more stable to use and less prone to deformation.

[0109] It is further necessary to add that Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in a specific implementation, according to an embodiment of the utility model, the present application further includes a plurality of lateral pushing devices 110;

[0110] Among them, the lifting device 20 is fixed on the upper end surface of the support frame 30, and its top is against the lower bottom surface of the floating slide rail 10; multiple horizontal pushing devices 110 are evenly fixed on the upper end surface of the support frame 30 in two rows and multiple columns from left to right, and the two rows of horizontal pushing devices 110 are correspondingly located on the front and rear sides of the floating slide rail 10, and are both facing the floating slide rail 10, so as to push the floating slide rail 10 and adjust the lateral position of the front and rear ends of the floating slide rail 10, and are also used to lock the floating slide rail 10 when it clamps the floating slide rail 10.

[0111] From this, it can be clearly seen that:

[0112] On the one hand, since the two rows of the lateral pushing devices 110 are correspondingly located on the front and rear sides of the floating slide rail 10 and are both facing the floating slide rail 10, when the thrusts of the two rows of the lateral pushing devices 110 on the front and rear sides of the floating slide rail 10 are different, the floating slide rail 10 can be driven to rotate slightly in the lateral direction to adjust its position in the lateral direction so that its left and right ends can better correspond to and connect with the right end of the fixed slide rail A3000 and the left end of the fixed slide rail B5000.

[0113] On the other hand, refer to Figure 5 As shown, after the position of the floating slide rail 10 in the lateral direction is adjusted, it can be slightly clamped and fixed by the two rows of lateral pushing devices 110, so that it can be supported with better stability.

[0114] Preferably, in the present technical solution, the lateral pushing device 110 is also preferably a lifting cylinder, a screw-driven linear module or a cylinder-driven linear module, etc.

[0115] It is further necessary to add that in the specific implementation, the reference diagram and Figure 2 As shown, according to one embodiment of the utility model, the present application further includes a longitudinal limiting plate 120 and abutting plate 130;

[0116] The longitudinal limit plate 120 is fixed upward on the right side of the upper end surface of the support frame 30 ; the abutment plate 130 is fixed downward on the right side of the lower bottom surface of the floating slide rail 10 , and its right end surface abuts against the left end surface of the longitudinal limit plate 120 .

[0117] Therefore, for the floating slide rail 10 described in the present application, no matter how its lifting and lowering or its lateral position is controlled to be fine-tuned, the abutment plate 130 at its right end is always difficult to cross the longitudinal limit plate 120, so that its right end is not easy to hit the independent offshore structure B4000 and / or the fixed slide rail B5000, making the present application safer, more reliable and more dependable to use.

[0118] At the same time, for the use of this application, the lifting device 20, the auxiliary lifting device 60, the driving device 702 and the lateral pushing device 110 can all be connected to a main control device so that they can be comprehensively controlled by the main control device. In this way, the application can be made highly intelligent, making it faster and more convenient to operate.

[0119] Furthermore, for the use of the present application, a laser alignment instrument connected to the main control device may be provided on the floating slide rail 10, so as to detect the height, horizontality and lateral position of the floating slide rail 10 through the laser alignment instrument, so as to transmit the detected real-time data to the main control device. In this way, the main control device can control the lifting device 20, the auxiliary lifting device 60, the driving device 702 and the lateral pushing device 110 to work together according to the received real-time data, so as to quickly correct the position of the floating slide rail 10, so that the floating slide rail 10 can finally be adjusted to the required height, horizontality and lateral position for its use, so as to realize a more intelligent use of the present application.

[0120] Other embodiments and the like are not described here by way of example.

[0121] To sum up, in the rotatable drilling rig slide rail system 1000 provided in the present application, during specific implementation, the floating slide rail 10 plays a role of transition, and its upper and lower heights are adjustable, so that during use, it can be raised to be flush with the fixed slide rail A3000 and / or the fixed slide rail B5000 at any time, so that the drilling rig module as described in the background technology can be transferred from the fixed slide rail A3000 to the fixed slide rail B5000 through the floating slide rail 10 flush with it, or from the fixed slide rail B5000 to the fixed slide rail A3000 through the floating slide rail 10 flush with it, so that the present application is convenient to use and flexible and reliable to use.

[0122] Furthermore, during the use of the present application, the left end of the floating rail 10 is only connected to the right end of the fixed rail A3000 but not directly connected and fixed thereto, and the right end is only connected to the left end of the fixed rail B5000 but not directly connected and fixed thereto, so that it is not a rigid connection and is not easy to cause relative displacement at the connection under conditions such as wind, waves and currents, thereby causing damage to the structure at the connection. In other words, the present application can effectively avoid related problems during actual use and prolong its service life. In the technical solution of the present application, the support frame 30 is connected and fixed to the offshore independent structure A2000 through the fixed shaft 50, and on the basis of its difficulty in displacement, the floating rail 10 supported thereon is also not easy to shift.

[0123] In addition, since the fixed shaft sleeve 40 is vertically fixed on the independent offshore structure A2000, the upper end of the fixed shaft 50 is sleeved in the fixed shaft sleeve 40, and the left end of the support frame 30 extends to the bottom of the independent offshore structure A2000, and a sleeve hole A is provided in the left middle portion thereof, which penetrates through the upper and lower end surfaces and is fixed to the outside of the fixed shaft 50. Therefore, the support frame 30 can rotate around the fixed shaft 50, so that the position of the floating slide rail 10 supported thereon in the lateral direction can be adjusted, making it more flexible to use. Since the present application also includes the auxiliary lifting device 60, the auxiliary lifting device 60 is fixed on the upper left end surface of the support frame 30, and its top is against the bottom of the offshore independent structure A2000. Therefore, when using the present application, the floating slide rail 10 will generate downward pressure on the right part of the support frame 30, so that the left part of the support frame 30 will be tilted up and generate a force on the fixed shaft 50 to the lower right. By controlling the auxiliary lifting device 60 to rise and fall to a suitable height so that its top is against the bottom of the offshore independent structure A2000, at this time, the bottom of the offshore independent structure A2000 will generate a downward force on the whole formed by the auxiliary lifting device 60 and the left part of the support frame 30. In this way, the stability of the left and right ends of the support frame 30 can be better controlled, so that it can support the floating slide rail 10 more stably. At the same time, it can also weaken the force generated by it on the fixed shaft 50 to the lower right, so that the service life of the fixed shaft 50 is long.

[0124] Furthermore, the present application sets the push-pull device so that the support frame 30 and the floating slide 10 supported thereon can be controlled to rotate between the first position and the second position. While being able to adjust the lateral position of the floating slide 10, when the present application is not in use, the push-pull device can be used to control the support frame 30 to rotate to the second position so that the floating slide 10 supported thereon deviates from the fixed slide B5000. In this way, there is basically no object between the offshore independent structure A2000 and the offshore independent structure B4000, so that they do not affect each other when different displacements occur, and the floating slide 10 is not easily hit by the offshore independent structure A2000 and the offshore independent structure B4000 when they are displaced when not in use.

[0125] Thirdly, since the two rows of the lateral pushing devices 110 are located at the front and rear sides of the floating rail 10 and are both facing the floating rail 10, when the thrusts of the two rows of the lateral pushing devices 110 on the front and rear sides of the floating rail 10 are different, the floating rail 10 can be driven to rotate slightly in the lateral direction to adjust its position in the lateral direction so that its left and right ends can better correspond to the right end of the fixed rail A3000 and the left end of the fixed rail B5000. After the position of the floating rail 10 in the lateral direction is adjusted, it can be slightly clamped and fixed by the two rows of the lateral pushing devices 110 so that it is more stable when supported.

[0126] Furthermore, the rotatable drilling rig slide rail system 1000 provided in the present application can adjust and correct the height, horizontality and lateral position of the provided floating slide rail 10 under the coordinated action of the lifting device 20, the auxiliary jacking device 60, the driving device 702 and the lateral pushing device 110, so that the floating slide rail 10 can finally be adjusted to the required height, horizontality and lateral position for use. During use, it has strong stability, flexible and reliable use, and can better solve the defect problem caused by the rigid connection slide rail between the offshore independent structure A2000 and the offshore independent structure B4000 in the prior art for the sliding of the drilling rig module as described in the background technology, so that the present application is indeed extremely practical and has an excellent use effect. The present application will inevitably have a good market promotion value, and the present application will inevitably be very popular and will be effectively popularized.
