[0025] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0026] The embodiments of the present utility model disclose a jacket horizontal roll-on / roll-off ship transportation load sharing device.

[0027] According to the appendix Figure 1As shown in FIGS. 1-4, it includes a box-shaped main body structure 100, a stability-enhancing and strengthening support plate 200, and a rectangular rib plate 300. The box-shaped main body structure 100, the stability-enhancing and strengthening support plate 200, and the rectangular rib plate 300 are all prefabricated from steel plates of different materials and thicknesses according to usage requirements, so that the box-shaped main body structure 100, the stability-enhancing and strengthening support plate 200, and the rectangular rib plate 300 have relatively high load-bearing strength. A fixed connection horse row 102 is fixedly connected to the top end of the box-shaped main body structure 100, and the fixed connection horse row 102 is used to connect the ship-loading lifting beam. The stability-enhancing and strengthening support plate 200 is fixedly arranged on both sides of the box-shaped main body structure 100, and the stability-enhancing and strengthening support plate 200 is used for the auxiliary support on the side of the box-shaped main body structure 100. The rectangular rib plate 300 is fixedly arranged inside the box-shaped main body structure 100, and the rectangular rib plate 300 is used for the auxiliary support inside the box-shaped main body structure 100; when the load-sharing device is in use, the wire winding needs to complete the SPMT vehicle group layout according to the ship-loading plan, and then hoist the transportation load-sharing device to the designated position on the SPMT vehicle board to complete the smooth docking work with the SPMT. After that, move the SPMT together with the load-sharing device to the designated position under the lifting beam at the bottom of the jacket. The SPMT jacks up the vehicle body until the top surface of the load-sharing device is level with the lifting beam to complete the docking of the load-sharing device with the ship-loading lifting beam. Subsequently, weld the fixed connection horse row 102 to the ship-loading lifting beam to ensure that the load-sharing device and the lifting beam are firmly fixed. After preparation, transport the jacket to the designated location on the barge deck according to the transportation plan, cut the fixed connection horse row 102 and the lifting beam to release the fixation, and lower the vehicle body. The load-sharing device of this embodiment can be withdrawn synchronously with the SPMT vehicle body, thus completing the transportation and ship-loading operation of the jacket; among them, the box-shaped main body structure 100 is used to bear all the loads during the ship-loading and transportation operation. Its top end is butt-welded and fixed to the ship-loading lifting beam through the fixed connection horse row 102, and its bottom end is butted against the SPMT vehicle board; while the stability-enhancing and strengthening support plate 200 can assist in improving the lateral support stability of the box-shaped main body structure 100, the lens is to enhance the overall load-bearing capacity, and the rectangular rib plate 300 can enhance the internal structural strength of the box-shaped main body structure 100. In this way, it can play a role in dispersing the transportation load of the jacket, controlling the deformation of the transportation equipment, and ensuring the safety of the jacket ship-loading operation.

[0028] It should be noted that there is at least one box-shaped main structure 100. The length of the box-shaped main structure 100 is generally between 4 and 10 meters. The specific quantity can be selected according to the requirements of the specific application environment. Flange connection plates 103 are fixedly connected to both ends of the box-shaped main structure 100. The flange connection plates 103 are used for the fixation of the splicing of two adjacent box-shaped main structures 100. Through the flange connection plates 103, two adjacent box-shaped main structures 100 can be butt-jointed front and back, and the box-shaped main structures 100 at the front and back positions are fixed by installing bolts and nuts on the two adjacent flange connection plates 103. The increase in the quantity of the box-shaped main structures 100 can improve the transportation weight of the sub-loaded jacket and reduce the deformation amplitude of the SPMT vehicle deck, ensuring the safety of ship loading and transportation. In a preferred embodiment, the box-shaped main structure 100 includes a plurality of H-shaped steel plates 101. The plurality of H-shaped steel plates 101 are sequentially attached and spliced along the same straight line. The box-shaped main structure 100 is composed of a single or multiple H-shaped steel plates 101 with an H-shaped cross-section spliced together, which can disperse the transportation load of the jacket, control the deformation of the transportation equipment, and ensure the safety of the jacket ship loading operation. The rectangular rib plate 300 is located in the cavity area between two adjacent H-shaped steel plates 101. The rectangular rib plate 300 is used to divide the cavity area between two adjacent H-shaped steel plates 101 into box-shaped cavities. The rectangular rib plate 300 can be selected with different specifications according to the weight of the jacket and the height of the ship loading lifting beam docked with it, so as to achieve the purpose of improving the structural strength of the box-shaped main structure 100. Through the assembly of the rectangular rib plate 300, the interior of the box-shaped main structure 100 can be divided into box-shaped cavities, improving the stiffness of the box-shaped main structure 100.

[0029] Furthermore, the stability-enhancing and strengthening support plates 200 located on both sides of the box-shaped main structure 100 are symmetrically arranged and are multiple. The multiple stability-enhancing and strengthening support plates 200 located on the same side of the box-shaped main structure 100 are arranged in parallel at intervals. The stability-enhancing and strengthening support plates 200 are fixedly connected to the outer side wall of the outermost H-shaped steel plate 101 in the box-shaped main structure 100. The stability-enhancing and strengthening support plates 200 can be prefabricated into a specific width according to the size of the vehicle layout space. A connection slot 202 is opened at the bottom of the side of the stability-enhancing and strengthening support plate 200 facing the H-shaped steel plate 101. The height of the connection slot 202 matches the thickness of the bottom position of the H-shaped steel plate 101. The setting of the connection slot 202 enables the bottom of the stability-enhancing and strengthening support plate 200 to better fit the width of the bottom position of the side wall of the H-shaped steel plate 101, so that the bottom end of the stability-enhancing and strengthening support plate 200 can be on the same horizontal plane as the bottom end of the box-shaped main structure 100, thereby achieving the stability of the lateral auxiliary support for the box-shaped main structure 100.

[0030] In addition, lifting lugs 201 are fixedly provided on both sides of the box-shaped main body structure 100. The lifting lugs 201 are used for the hoisting of the load sharing device. There are two lifting lugs 201 located at the same side position of the box-shaped main body structure 100. The lifting lugs 201 are fixedly connected to the stability-enhancing and strengthening support plates 200 at the corresponding positions. A vertical notch is formed at the top of the side wall of the stability-enhancing and strengthening support plate 200 fixedly connected to the lifting lug 201. The lifting lug 201 can be prefabricated from a steel plate. The lifting lug 201 can assist in the hoisting of the load sharing device, making the load sharing device more maneuverable.
