Description

Technical Field

[0001] The invention relates to the technical field of foundation structures of marine engineering, and in particular to a suction cylinder transport and fixing device. Background Art

[0002] The development of offshore wind farms has gradually received more and more attention and participation. The construction of offshore wind farms needs to consider the basic structure form for equipment installation, such as offshore wind towers and offshore wind turbine foundations. Traditional foundation types include gravity foundations and single pile foundations. Currently, the most commonly used foundation types include steel pipe pile foundations (wind towers), tripod foundations, conductor frame foundations, and suction tube foundations (wind turbines). Among these foundation types, the construction process of steel pipe piles, single piles, tripods, conductor frames and other foundation types is complex, and transportation and installation require large machinery for transportation and hoisting, so the construction period is long and the construction cost is high. It is difficult to accurately grasp the pile positioning and torsion angle, and the pile efficiency is relatively low. The gravity foundation relies on the weight of the structure as a whole and the weight of the filler and ballast on it to resist external loads and maintain structural stability. The construction principle is simple, the cost of filler and ballast materials is low, and the construction cost is also low for shallow foundations; but for deep waters where the weight and geometric dimensions of the foundation are large, the foundation occupies a wide range of the seabed, and there are also requirements for seabed conditions, the construction, transportation methods and costs are all restricted, so the gravity foundation is applicable to a limited water depth range. The suction tube foundation has strong bearing capacity, simple transportation and installation, and relatively easy recovery. At the same time, the suction tube foundation has a simple structure and is applicable to a wide range of seabed conditions. At the same time, the tube skirt has high anti-slip stability, and the construction and installation principle is simple.

[0003] However, the wall of the suction cylinder is relatively thin, and a suitable transportation fixture is required to fix the suction cylinder on the deck of the transport ship during transportation. At present, most suction cylinder fixtures use steel components to weld the suction cylinder to the transport ship hull, and then cut them apart when hoisting and lowering on site. The suction cylinder fixture is relatively complicated and cannot be reused. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art in which the suction cylinder is fixed on the transport hull by welding steel components, which has complex fixing methods and the suction cylinder fixing device cannot be reused, thereby providing a suction cylinder transportation fixing device.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A suction cylinder transport fixing device, comprising:

[0007] Support base;

[0008] The clamping structure comprises an inner clamping seat and an outer clamping seat connected to the support base and arranged opposite to each other, wherein a clamping space for clamping the wall of the suction cylinder is formed between the inner clamping seat and the outer clamping seat; at least one of the inner clamping seat and the outer clamping seat is slidably connected to the support base along the radial direction of the suction cylinder;

[0009] The adjusting structure is movably connected to the inner clamping seat and the outer clamping seat, and is used to adjust the clamping distance between the inner clamping seat and the outer clamping seat so that the inner clamping seat and the outer clamping seat cooperate to clamp or loosen the wall of the suction cylinder.

[0010] Furthermore, an inner buffer gasket is provided on the surface where the inner clamping seat is connected to the wall of the suction cylinder; and an outer buffer gasket is provided on the surface where the outer clamping seat is connected to the wall of the suction cylinder.

[0011] Furthermore, the adjustment structure includes an adjustment screw that passes through the inner clamping seat and the outer clamping seat, and an adjustment nut that is threadedly connected to the adjustment screw and is located on the surface of the inner clamping seat or the outer clamping seat that is away from the suction tube wall.

[0012] Furthermore, the support base is welded and fixed on the deck of the transportation vehicle.

[0013] Furthermore, the support base includes an outer support base and an inner support base which are arranged opposite to each other on the inner and outer sides of the suction cylinder wall; the inner clamping seat is fixedly connected to the inner support base, and the outer clamping seat is slidably connected to the outer support base along the radial direction of the suction cylinder.

[0014] Further, the outer support base includes an outer first support member extending in the circumferential direction of the suction cylinder wall, and an outer second support member connected to the outer first support member and extending in the radial direction of the suction cylinder; the inner support base includes an inner first support member extending in the circumferential direction of the suction cylinder wall, and an inner second support member connected to the inner first support member and extending in the radial direction of the suction cylinder.

[0015] Furthermore, there are at least two outer second supporting members connected to the outer first supporting member and arranged at intervals; and there are at least two inner second supporting members connected to the inner first supporting member and arranged at intervals.

[0016] Further, the outer first support member, the inner first support member, the outer second support member and the inner second support member are all H-shaped steels.

[0017] Furthermore, a T-shaped slide groove is provided on the outer clamping seat, which is slidably matched with the upper flange plate of the outer second supporting member; and an I-beam corresponding to the position of the T-shaped slide groove is also provided in the outer clamping seat.

[0018] Furthermore, reinforcing rib plates are connected between the two sides of the web of the H-shaped steel and the lower flange plate, and the bottom of the reinforcing rib plate is welded to the deck of the transportation vehicle.

[0019] The technical solution of the present invention has the following advantages:

[0020] 1. The suction cylinder transportation and fixing device provided by the present invention installs a supporting base on a transportation tool. When the suction cylinder is transported, the wall of the suction cylinder is extended into the clamping space between the inner clamping seat and the outer clamping of the clamping structure. The distance between the inner clamping seat and the outer clamping is reduced by adjusting the structure, so that the inner clamping seat and the outer clamping seat cooperate to clamp the wall of the suction cylinder, which can ensure the reliability of the suction cylinder during transportation. Compared with the method of welding and fixing the suction cylinder on the transportation tool in the prior art, the operation is simpler and faster. When the suction cylinder is hoisted and lowered, the distance between the inner clamping seat and the outer clamping is increased by adjusting the structure, so that the inner clamping seat and the outer clamping seat loosen the wall of the suction cylinder, and the hoisting equipment can hoist and lower the suction cylinder. Compared with the method of separating the suction cylinder and the transportation tool by cutting in the prior art, the workload is greatly reduced. In addition, the distance between the inner clamping seat and the outer clamping seat is adjustable, which can match suction cylinders with different outer diameters and wall thicknesses to meet the transportation requirements of various types of suction cylinders; moreover, the suction cylinder transportation fixing device can be reused, greatly reducing the transportation cost of the suction cylinder.

[0021] 2.

[0023] 4. In the suction cylinder transport fixing device provided by the present invention, the support base is fixed on the deck of the transportation tool by welding, which can improve the firmness of the support base installation structure and further improve the stability of the suction cylinder during transportation.

[0024] 5. The suction cylinder transport and fixing device provided by the present invention has an outer clamping seat that is slidably connected to the outer supporting base along the radial direction of the suction cylinder, which makes it more convenient for workers to adjust the installation position of the outer clamping seat on the outer supporting base outside the suction cylinder.

[0025] 6. In the suction cylinder transport and fixing device provided by the present invention, the outer second support member plays a structural reinforcement role on the outer first support member; the inner second support member also plays a structural reinforcement role on the inner first support member, and together they can meet the strength requirements of the suction cylinder for the support base.

[0026] 7. The suction cylinder transport and fixing device provided by the present invention has at least two outer second supporting members connected to the outer first supporting member, and at least two inner second supporting members connected to the inner first supporting member; the supporting strength of each part of the supporting base can meet the supporting strength requirement of the suction cylinder, avoiding the displacement of the supporting base due to weak local supporting strength, and reducing the size of the supporting base and the amount of steel used while ensuring that the suction cylinder is firmly installed on the transport and fixing device.

[0027] 8. The suction cylinder transport and fixing device provided by the present invention has the advantages of strong bending resistance, low cost, and easy construction, due to the more optimized cross-sectional area distribution of the H-shaped steel and the more reasonable strength-to-weight ratio. The H-shaped steel is used as the first outer support member, the first inner support member, the second outer support member, and the second inner support member. The cost of the support base can be reduced while ensuring that the structural strength of the support base meets the support requirements of the suction cylinder.

[0028] 9. In the suction cylinder transport and fixing device provided by the present invention, the upper flange plate of the outer second supporting member serves as a sliding guide for the outer clamping seat through the T-shaped groove, which can better ensure that the outer clamping seat slides along the radial direction of the suction cylinder, and the adjustment structure is convenient to drive the outer clamping seat and the inner clamping seat to better cooperate to clamp or release the wall of the suction cylinder; and an I-beam is arranged on the outer clamping seat at the position corresponding to the T-shaped groove, which can strengthen the structural strength of the part of the outer clamping seat with the T-shaped groove, so that the structural strength of each part of the outer clamping seat can meet the support strength requirements of the suction cylinder.

[0029] 10. The suction cylinder transport fixing device provided by the present invention has reinforcing ribs between the two sides of the web of the H-shaped steel and the lower flange plate, which can further enhance the structural strength of the H-shaped steel, and the bottom of the reinforcing ribs is welded to the deck of the transport vehicle, which can improve the connection firmness between the H-shaped steel and the deck of the transport vehicle, that is, improve the installation firmness of the support base on the deck of the transport vehicle, thereby improving the stability of the suction cylinder during transportation.

[0030] 11. The suction cylinder transport fixing device provided by the present invention, wherein a plurality of suction cylinder transport fixing devices are respectively fixed at different positions of the suction cylinder wall, can improve the stability of the suction cylinder during transportation.

[0036] The technical solution of the present invention will be described clearly and completely below 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 creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] like Figure 1 -3 shows a suction cylinder transport fixing device, comprising a support base 1, a clamping structure 2 and an adjustment structure 3; the suction cylinder is fixed on a transport vehicle through a plurality of suction cylinder transport fixing devices located below the suction cylinder wall 4. Among them, the clamping structure 2 comprises an inner clamping seat 22 and an outer clamping seat 21 connected to the support base 1 and respectively arranged on the inner and outer sides of the suction cylinder wall 4, and a clamping space for clamping the suction cylinder wall 4 is formed between the inner clamping seat 22 and the outer clamping seat 21; at least one of the inner clamping seat 22 and the outer clamping seat 21 is slidably connected to the support base 1 along the radial direction of the suction cylinder. The adjustment structure 3 is movably connected to the inner clamping seat 22 and the clamping seat, and is used to adjust the clamping distance between the inner clamping seat 22 and the outer clamping seat 21, so that the inner clamping seat 22 and the outer clamping seat 21 cooperate to clamp or release the suction cylinder wall 4.

[0041] The support base 1 is installed on the transport vehicle. When the suction cylinder is transported, the suction cylinder wall 4 is extended into the clamping space between the inner clamping seat 22 and the outer clamping seat of the clamping structure 2. The spacing between the inner clamping seat 22 and the outer clamping seat is reduced by adjusting the structure 3, so that the inner clamping seat 22 and the outer clamping seat 21 cooperate to clamp the suction cylinder wall 4. This ensures the reliability of the suction cylinder during transportation. Compared with the method of welding the suction cylinder to the transport vehicle in the prior art, the operation is simpler and faster. When the suction cylinder is hoisted and lowered, the spacing between the inner clamping seat 22 and the outer clamping seat is increased by adjusting the structure 3, so that the inner clamping seat 22 and the outer clamping seat 21 release the suction cylinder wall 4. The hoisting equipment can hoist and lower the suction cylinder. Compared with the method of separating the suction cylinder and the transport vehicle by cutting in the prior art, the workload is greatly reduced. In addition, the distance between the inner clamping seat 22 and the outer clamping seat 21 is adjustable, which can match suction cylinders with different outer diameters and wall thicknesses to meet the transportation requirements of various types of suction cylinders; moreover, the suction cylinder transportation fixing device can be reused, greatly reducing the transportation cost of the suction cylinder.

[0042] In this embodiment, the surface where the inner clamping seat 22 is connected to the suction cylinder wall 4 is provided with an inner buffering pad 23; the surface where the outer clamping seat 21 is connected to the suction cylinder wall 4 is provided with an outer buffering pad 24. The inner buffering pad 23 and the outer buffering pad 24 play a role of buffering, maintaining balance and shock absorption on both sides of the suction cylinder wall 4, which can better ensure the reliability of the suction cylinder during transportation.

[0043] In this embodiment, the adjustment structure 3 includes an adjustment screw 31 that passes through the inner clamping seat 22 and the outer clamping seat 21, and an adjustment nut 32 that is threadedly connected to the adjustment screw 31 and is located on the surface of the outer clamping seat 21 on the side facing away from the suction tube wall 4. The adjustment structure 3 composed of the adjustment screw 31 and the adjustment nut 32 has the advantages of simple structure and easy adjustment. The adjustment nut 32 is located on the surface of the outer clamping seat 21 on the side facing away from the suction tube wall 4, which is convenient for the staff to make adjustments outside the suction tube. In an alternative embodiment, the adjustment nut 32 can also be located on the surface of the inner clamping seat 22 on the side facing away from the suction tube wall 4, or on the surfaces of the outer clamping seat 21 and the inner clamping seat 22 on the side facing away from the suction tube wall 4.

[0044] In this embodiment, the support base 1 is welded and fixed to the deck of the transport vehicle. The support base 1 is fixed to the deck of the transport vehicle by welding, which can improve the firmness of the installation structure of the support base 1, thereby improving the stability of the suction cylinder during transportation. In an alternative embodiment, the support base 1 can also be detachably fixed to the transport vehicle by high-strength bolts; the support base 1 is fixed to the transport vehicle by a detachable installation method, and the installation position of the support base 1 on the transport vehicle can be adjusted according to the size of the suction cylinder, which is more flexible.

[0045] In this embodiment, the support base 1 includes an outer support base 11 and an inner support base 12 which are arranged opposite to each other on the inner and outer sides of the suction cylinder wall 4. The inner clamping seat 22 is fixedly connected to the inner support base 12, and the outer clamping seat 21 is slidably connected to the outer support base 11 along the radial direction of the suction cylinder. The outer support base 11 includes an outer first support member 111 extending along the circumferential direction of the suction cylinder wall 4, and an outer second support member 112 connected to the outer first support member 111 and extending along the radial direction of the suction cylinder. The inner support base 12 includes an inner first support member 121 extending along the circumferential direction of the suction cylinder wall 4, and an inner second support member connected to the inner first support member 121 and extending along the radial direction of the suction cylinder. The outer second support member 112 plays a role of structural reinforcement for the outer first support member 111; the inner second support member also plays a role of structural reinforcement for the inner first support member 121, and the combination can meet the strength requirements of the suction cylinder for the support base 1. The inner clamping seat 22 connected to the inner first support member 121 and the outer clamping seat 21 connected to the outer first support member 111 both extend along the circumferential direction of the suction cylinder wall 4, which better facilitates the installation and fixation of the suction cylinder wall 4 between the outer clamping seat 21 and the inner clamping seat 22.

[0046] Specifically, there are two outer second support members 112 connected to the outer first support member 111 and they are arranged at intervals; there are also two inner second support members connected to the inner first support member 121 and they are arranged at intervals. In an alternative embodiment, the number of the outer second support members 112 and the inner second support members can also be one, three or more, and the specific selection can be more adaptive. At least two outer second support members 112 are connected to the outer first support member 111, and at least two inner second support members are connected to the inner first support member 121; the support strength of each part of the support base 1 can meet the support strength requirements of the suction cylinder, avoiding the displacement of the support base 1 due to weak local support strength, and reducing the size of the support base 1 and the amount of steel used on the premise of ensuring that the suction cylinder is firmly installed on the transportation fixture.

[0047] In this embodiment, the outer clamping seat 21 has two outer extension seats 213 extending to the upper part of the outer first supporting member 111, and the inner clamping seat 22 also has two inner extension seats 213 extending to the upper part of the inner first supporting member 121. The provision of the outer extension seats 213 on the outer clamping seat 21 and the inner clamping seat 22 on the inner clamping seat 22 can improve the bending resistance and structural strength of the outer clamping seat 21 and the inner clamping seat 22.

[0048] In this embodiment, the outer first support member 111, the inner first support member 121, the outer second support member 112 and the inner second support member are all H-shaped steel. Since the cross-sectional area distribution of H-shaped steel is more optimized, the strength-to-weight ratio is more reasonable, and it has the advantages of strong bending resistance, low cost, and easy construction, H-shaped steel is used as the outer first support member 111, the inner first support member 121, the outer second support member 112 and the inner second support member, the cost of the support base 1 can be reduced while ensuring that the structural strength of the support base 1 meets the requirements of the suction cylinder support.

[0049] In this embodiment, a T-shaped slot 211 is provided on the outer clamping seat 21 to slide with the upper flange plate of the outer second support member 112; an I-beam 212 is also provided in the outer clamping seat 21 to correspond to the position of the T-shaped slot 211. The upper flange plate of the outer second support member 112 plays a role of sliding guide for the outer clamping seat 21 through the T-shaped slot 211, which can better ensure that the outer clamping seat 21 slides along the radial direction of the suction cylinder, and facilitate the adjustment structure 3 to drive the outer clamping seat 21 and the inner clamping seat 22 to better cooperate to clamp or release the suction cylinder wall 4; and the I-beam 212 is provided on the outer clamping seat 21 corresponding to the position of the T-shaped slot 211, which can strengthen the structural strength of the portion of the outer clamping seat 21 with the T-shaped slot 211, so that the structural strength of each part of the outer clamping seat 21 can meet the support strength requirements of the suction cylinder.

[0050] In this embodiment, a reinforcing rib plate 25 is connected between the web and the lower flange of the H-shaped steel, and the bottom of the reinforcing rib plate 25 is welded to the deck of the transport vehicle. The provision of the reinforcing rib plate 25 between the web and the lower flange of the H-shaped steel can further enhance the structural strength of the H-shaped steel, and the bottom of the reinforcing rib plate 25 is welded to the deck of the transport vehicle, which can improve the connection firmness between the H-shaped steel and the deck of the transport vehicle, that is, improve the installation firmness of the support base 1 on the deck of the transport vehicle, thereby improving the stability of the suction cylinder during transportation.

[0051] To sum up, the suction cylinder transportation and fixing device provided in the embodiment of the present invention adjusts the distance between the inner clamping seat 22 and the outer clamping seat by adjusting the screw 31, so that the inner clamping seat 22 and the outer clamping seat 21 cooperate to clamp or loosen the suction cylinder wall 4, which can ensure the reliability of the suction cylinder during transportation. Compared with the method of welding and fixing the suction cylinder on the transportation tool in the prior art, the operation is simpler and faster; when the suction cylinder is hoisted and lowered, the suction cylinder and the transportation tool can be separated without cutting, which greatly reduces the workload; in addition, the distance between the inner clamping seat 22 and the outer clamping seat 21 is adjustable, which can be matched with suction cylinders with different outer diameters and wall thicknesses to meet the transportation requirements of various types of suction cylinders; moreover, the suction cylinder transportation and fixing device can be reused, which greatly reduces the transportation cost of the suction cylinder.

[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
