Description
Technical Field
[0001] The present invention belongs to the technical field of pipe rack transportation, and in particular relates to a transport device for loading an offshore wind power pipe rack onto a ship. Background Art
[0002] Wind turbine conductor rack is a bracket used for offshore wind power to support the wind turbine base. It is divided into shallow water area, medium water area and deep water area according to its height. The height of the conductor rack used in medium water area has reached 50 meters, and the weight is about 500-800 tons. When constructing the conductor rack in medium water area and deep water area, horizontal construction will be selected to ensure the safety and efficiency of construction. First, the conductor rack is divided into several parts, and then the construction personnel carry out the construction in sections on the platform composed of sliding shoes. After a part is built, the part is controlled to move forward so that this part is spliced with the previous part. After all the parts are welded, all the sliding shoes are controlled to move forward until the conductor rack enters the barge along the track.
[0003] When welding the conductor frame section, two reference columns must be determined first, and then the two reference columns are fixed before subsequent welding. In the existing method of fixing the reference columns, most of them are simply fixed nearby, which causes deviations when the subsequent conductor frame sections are combined with the previous sections. Equipment such as cranes are required for adjustment. Due to their large mass, the adjustment not only takes a lot of time, but also poses a great safety hazard when the conductor frame sections sway in the wind. Summary of the invention

[0008] Preferably, a rotating shaft is rotatably installed at the center of the loading platform, a first gear is fixedly sleeved on the rotating shaft, the first gear is located in a third slide groove, and racks are fixedly connected to opposite sides of the two sliders, and the racks are meshed with the first gear.
[0009] Preferably, the side rails are provided with a plurality of notches on the side facing the main track, and the plurality of notches are equidistantly distributed and face the same direction as the forward direction of the carrier mechanism.
[0010] Preferably, one end of the secondary track facing the main track is fixedly connected with a hinged head, the hinged head is located in a limiting groove provided on the bottom surface of the main track, the top surface of the main track is penetrated by a locking pin, and the locking pin is inserted in the hinged head.
[0011] Preferably, a plurality of mounting holes are provided on the top surface of the loading platform, a one-way bearing is fixedly installed in the mounting hole, a mounting shaft is fixedly sleeved inside the one-way bearing, and a second gear is fixedly sleeved on the side of the mounting shaft.
[0012] Preferably, part of the teeth of the second gear are located in the notch, and when the carrier mechanism moves forward, the second gear meshes with the notch to drive the mounting shaft to rotate.
[0013] Preferably, a proximity sensor is fixedly provided on the top surface of the main track, and the proximity sensor is close to the limiting groove on the bottom surface of the main track and away from the side of the auxiliary track.
[0014] Preferably, the fixed end of the lifting and telescopic rod is fixedly connected to an installation space opened below the main track, and a plurality of mounting seats are also fixedly connected to the inner bottom surface of the installation space. The mounting seats are hinged with a supporting connecting rod, and a second sliding groove is opened on the side of the supporting connecting rod. The supporting connecting rod is movably connected to the side of the first sliding column through the second sliding groove.
[0015] The beneficial effects of the present invention are as follows:
[0016] 1. In the present invention, by setting the rack and the first gear, at the initial stage of welding, after determining the two reference columns, the reference columns are clamped between the first clamp block and the second clamp block, and the rotation of the rotating shaft is controlled to make the first gear drive the racks on both sides to move, thereby making the two sliders move relative to each other. At this time, the two reference columns are at the same distance from the center of the loading platform. During the segmented welding process, it is only necessary to adjust the distance between the two first clamp blocks and the rotation angle of the second slide column to ensure the accuracy of the subsequent overall connection. The segmented brackets can be docked by simply pushing the rear loading platform forward without the need for complicated measurements. At the same time, when the above structure controls the movement of the two reference columns, it can always ensure that the center of gravity of the segmented part of the welded bracket is always in the middle, preventing rollover during movement and ensuring safety during transportation.
[0017] 2. In the present invention, after the bracket is welded, the carrier mechanism is controlled to move forward so that the carrier fixed with the carrier mechanism moves forward. At this time, as the frontmost sliding shoe covers the proximity sensor, the proximity sensor is triggered, causing the telescopic end of the lifting telescopic rod to rise, thereby driving the first sliding column to slide upward in the first sliding groove. As the first sliding column moves upward, it drives the supporting connecting rod to move. After the top surface of the fixed block on the first sliding column abuts against the bottom surface of the limit block, as the lifting telescopic rod continues to extend, it drives the limit block to move upward together until the limit block is embedded in the limit groove. As the limit block is embedded, the secondary track is aligned with the main track. By fixedly connecting the secondary track with the track on the barge, when the carrier platform moves toward the barge, the sliding shoe will not collide with the conveying rail due to deviation of the track, causing damage to the inside of the sliding shoe and making it impossible to use it normally.
[0018] 3. In the present invention, by setting the notch and the second gear, as the loading platform moves forward, the second gear meshes with the notch and rotates. At this time, when the auxiliary track deflects inward due to the gap between the limit groove and the limit block, the second gear moves and rotates itself, so that the second gear pushes the auxiliary track to deflect outward, so that the inward-deflected auxiliary track is corrected, thereby ensuring that the main track and the auxiliary track are on the same track, further ensuring the smooth and safe movement of the sliding shoe.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.
[0026] like Figures 1 to 5 As shown, an embodiment of the present invention provides an offshore wind power pipe rack ship loading and transporting device, including a bracket 1 and a conveying rail 2, the conveying rail 2 includes two parallel main rails 21, and also includes:
[0027] The main track 21 is hingedly connected to the end of the barge with the auxiliary track 22, and the bottom surfaces of the main track 21 and the auxiliary track 22 are provided with connected limiting grooves 23, and the sides of the main track 21 and the auxiliary track 22 are fixedly connected with side rails 24. The conveying rail 2 also includes a limiting block 29 located directly below the limiting groove 23, and the bottom surface of the limiting block 29 is fixedly connected with a plurality of fixed seats 210, and the side surfaces of the fixed seats 210 are provided with connected first sliding grooves 211, and the first sliding column 212 is slidably connected in the first sliding groove 211, and the side surfaces of the first sliding column 212 are fixedly connected with a plurality of fixed blocks 216, and the bottom surfaces of the fixed blocks 216 are fixedly connected with lifting telescopic rods 217;
[0028] The loading mechanism 3 includes a plurality of sliding shoes 32 slidably connected to the main rail 21, the top surfaces of two sliding shoes 32 are fixedly connected to the loading platform 31, the top surface of the loading platform 31 is provided with symmetrically arranged guide grooves 33, the inner side surface of the guide grooves 33 is provided with a third sliding groove 39, a symmetrical slider 310 is slidably connected in the third sliding groove 39, a second sliding column 34 slidably connected in the guide groove 33 is rotatably installed at the center of the slider 310, a first clamping block 35 is fixedly connected to the top surface of the second sliding column 34, and a second clamping block 36 is hinged on the side of the first clamping block 35.
[0029] In the present invention, by setting the rack 311 and the first gear 38, at the initial stage of welding, after determining the two reference columns, the reference columns are clamped between the first clamp block 35 and the second clamp block 36, and the rotation of the rotating shaft 37 is controlled, so that the first gear 38 drives the racks 311 on both sides to move, and then the two sliders 310 move relative to each other. At this time, the two reference columns are at the same distance from the center of the loading platform 31. During the segmented welding process, it is only necessary to adjust the distance between the two first clamp blocks 35 and the rotation angle of the second slide column 34 to ensure the accuracy of the subsequent overall connection. It is only necessary to push the rear loading platform 31 forward to dock the segmented bracket 1 without the need for complicated measurements. At the same time, when the above structure controls the movement of the two reference columns, it can always ensure that the center of gravity of the segmented part of the welded bracket 1 is always in the middle, preventing rollover during movement and ensuring safety during transportation.
[0030] Secondly, when the bracket 1 is welded, the carrier mechanism 3 is controlled to move forward, so that the bracket 1 fixed by the carrier mechanism 3 moves forward. At this time, as the frontmost sliding shoe 32 covers the proximity sensor 27, the proximity sensor 27 is triggered, so that the telescopic end of the lifting telescopic rod 217 rises, thereby driving the first slide post 212 to slide upward in the first slide groove 211. As the first slide post 212 moves upward, it drives the supporting connecting rod 213 to move, and the top surface of the fixing block 216 on the first slide post 212 abuts against After the bottom surface of the limit block 29 is reached, as the lifting telescopic rod 217 continues to extend, it drives the limit block 29 to move upward together until the limit block 29 is embedded in the limit groove 23. As the limit block 29 is embedded, the secondary track 22 and the main track 21 are aligned, and the secondary track 22 is fixedly connected to the track on the barge. At this time, when the loading platform 31 moves toward the barge, the slide shoe 32 will not collide with the conveying rail 2 due to the deviation of the track, causing the internal damage of the slide shoe 32 and unable to be used normally.
[0031] Finally, through the set notch 28 and the second gear 314, as the loading platform 31 moves forward, the second gear 314 engages with the notch 28 and rotates. At this time, when the auxiliary rail 22 deflects inward due to the gap between the limit groove 23 and the limit block 29, the second gear 314 moves and rotates itself, so that the second gear 314 pushes the auxiliary rail 22 to deflect outward, so that the inwardly deflected auxiliary rail 22 is corrected, thereby ensuring that the main rail 21 and the auxiliary rail 22 are on the same track, further ensuring the smooth and safe advancement of the sliding shoe 32.
[0032] Among them, a rotating shaft 37 is rotatably installed at the center of the loading platform 31, and a first gear 38 is fixedly sleeved on the rotating shaft 37. The first gear 38 is located in the third sliding groove 39. The opposite sides of the two sliders 310 are fixedly connected with racks 311, and the racks 311 are meshed with the first gear 38.
[0033] like Figure 4 and Figure 5 As shown, when welding the segments of the bracket 1, first fix the two reference columns between the first clamp 35 and the second clamp 36, and control the rotation of the shaft 37 by a power source such as a motor according to the spacing, and control the movement of the racks 311 on both sides by the first gear 38. After the distance between the two reference columns reaches the specified distance, rotate the first clamps 35 on both sides to make the two reference columns form a required angle. After the subsequent welding is completed, the center of gravity of the segment is always above the center of the loading platform 31, ensuring that during the subsequent transportation, the segment of the bracket 1 will not shake due to the deviation of the center of gravity, and then tip over.
[0034] A plurality of notches 28 are formed on the side of the side rail 24 facing the main track 21 . The notches 28 are evenly distributed and face the same direction as the forward direction of the object-carrying mechanism 3 .
[0035] Among them, a hinged joint 25 is fixedly connected to one end of the auxiliary rail 22 facing the main rail 21. The hinged joint 25 is located in a limiting groove 23 opened on the bottom surface of the main rail 21. The top surface of the main rail 21 is penetrated by a locking pin 26, and the locking pin 26 is inserted into the hinged joint 25.
[0036] from Figures 1 to 3 It can be seen that the main track 21 and the auxiliary track 22 still have a certain distance after being hinged. After the auxiliary track 22 and the track on the barge are fixed, when the barge is affected by the waves and shakes left and right, the auxiliary track 22 rotates around the locking pin 26, thereby preventing the ends of the main track 21 and the auxiliary track 22 from being squeezed and damaged due to direct abutment. After the subsequent loading platform 31 moves forward, the main track 21 and the auxiliary track 22 are positioned left and right through the guidance of the limit block 29 and the second gear 314, so that the main track 21 and the auxiliary track 22 are on the same track.
[0037] Among them, a plurality of mounting holes are opened on the top surface of the loading platform 31, and a one-way bearing 312 is fixedly installed in the mounting hole. A mounting shaft 313 is fixedly sleeved inside the one-way bearing 312, and a second gear 314 is fixedly sleeved on the side of the mounting shaft 313. Part of the teeth of the second gear 314 are located in the notch 28. When the loading mechanism 3 moves forward, the second gear 314 engages with the notch 28 to drive the mounting shaft 313 to rotate.
[0038] When the loading platform 31 is located on the main track 21, with the movement during transportation and the wind force acting on the bracket 1 segment, the loading platform 31 will move slightly left and right. At this time, after the loading platform 31 of the rear segment of the bracket 1 moves forward, this segment will deviate from the previous segment, resulting in the inability to align the welding when it is subsequently welded as a whole. If the welding is completed at this time, the center of gravity of the bracket 1 will shift after being erected, making the bracket 1 more susceptible to damage in the ocean. By meshing the second gears 314 and the notch 28 on both sides, as the loading platform 31 moves, the left and right errors generated by the loading platform 31 are offset through the contact between the second gear 314 and the notch 28, thereby ensuring accuracy during docking.
[0039] A proximity sensor 27 is fixedly disposed on the top surface of the main track 21 , and the proximity sensor 27 is close to the limiting groove 23 on the bottom surface of the main track 21 and is away from the side of the auxiliary track 22 .
[0040] Among them, the fixed end of the lifting and telescopic rod 217 is fixedly connected to the installation space opened below the main track 21, and the inner bottom surface of the installation space is also fixedly connected to multiple mounting seats 215. The mounting seats 215 are hinged with support links 213, and a second slide groove 214 is opened on the side of the support link 213. The support link 213 is movably connected to the side of the first slide column 212 through the second slide groove 214.
[0041] The installation space is located below the connection between the main rail 21 and the auxiliary rail 22, and is used to fix the mounting seat 215 and the lifting telescopic rod 217, that is, the connecting end of the auxiliary rail 22 and the main rail 21 is located on the ground, and the second slide groove 214 on the support connecting rod 213 makes it possible for the top end of the support connecting rod 213 to also abut against the bottom surface of the limit block 29 when the first slide column 212 is raised to the highest point and the top surface of the fixed block 216 abuts against the bottom surface of the limit block 29, providing support to the limit block 29, thereby preventing the bracket 1 on the loading platform 31 from applying pressure to the main rail 21 and the auxiliary rail 22 after the sliding shoe 32 passes over the limit groove 23, and then breaking.
[0042] Working principle:
[0043] When the segmented welding is initially started, the reference column is first fixed between the first clamp 35 and the second clamp 36 on the loading platform 31. Due to the action of the first gear 38 and the rack 311, the two reference columns are at the same distance from the center of the loading platform 31. Then the first clamp 35 is rotated to make the reference column face the designed angle, and then welding is performed.
[0044] After the segment welding is completed, the rear loading platform 31 is controlled to move forward until the segment of the bracket 1 on the rear loading platform 31 contacts the previous segment, so that the moving loading platform 31 stops moving. By setting the second gear 314 and the one-way bearing 312, the force generated by the contact between the segment bracket 1 on the moving loading platform 31 and the front segment will not cause the loading platform 31 to return in the opposite direction, thereby ensuring that the distance between the two segments is appropriate when connected, and through the action of the first gear 38 and the rack 311, the segment of the bracket 1 always remains at the center of the corresponding loading platform 31, and under the action of the second gears 314 on both sides, the loading platform 31 has the same distance from the side rails 24 on both sides, which eliminates the need for complicated measurements during docking and reduces construction time.
[0045] When all the segments are connected, the bracket 1 moves forward as a whole by moving multiple loading platforms 31 forward together. As the sliding shoe 32 moves forward and covers the proximity sensor 27, the telescopic rod 217 is extended, thereby pushing the limit block 29 to move upward. At this time, as the limit block 29 is embedded in the limit groove 23, the main track 21 and the auxiliary track 22 are merged. At this time, when the sliding shoe 32 continues to move forward, it will not collide with the auxiliary track 22 or the track on the barge, thereby preventing the sliding shoe 32 from deformation or damage.
