Description

Technical Field

[0001] This utility model relates to the field of construction of pile-based jacket platform, and in particular to an auxiliary transportation device for the vertical construction of jacket. Background Technology

[0002] A jacket platform is a spatial frame structure welded from several vertical legs and horizontal and diagonal connecting steel pipes. After prefabrication on land, it is towed to its position at sea. Piling operations then secure the jacket platform to the seabed, providing stable support for the entire production platform. The construction of jacket platforms has profound significance for the development of oil and gas resources. Jacket platforms are generally constructed using horizontal slipways, employing a towing and sliding loading process. This results in the need for slipway resources, a large site area, slow loading speed, and a relatively long project duration, leading to limited site-specific jacket production capacity and generally low economic benefits. Vertical, non-slipway construction, on the other hand, has the advantages of a smaller footprint, easier loading, and shorter construction period, thus overcoming the aforementioned drawbacks.

[0003] The main problem with vertical construction of jacket supports is that jacket supports usually have 4 legs, which can only be supported by 4 sets of tooling. This places high demands on the structural strength of the tooling and the connection strength of the jacket legs, and requires even distribution of pressure. Existing support tooling is difficult to meet the needs of vertical construction and transportation of heavy 4-legged jacket supports. Utility Model Content

[0004] To overcome the above problems, this utility model provides an auxiliary transportation device for the upright construction of a guide frame. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0005] An auxiliary transportation device for the upright construction of a jacket structure includes a load-bearing base, on which a supporting leg is coaxially mounted. Several reinforcing ribs are symmetrically arranged around the supporting leg. The top of the supporting leg is fixedly connected to a leg of the jacket structure, and the bottom of the supporting leg is fixedly connected to the load-bearing base through the reinforcing ribs. Load-sharing structures are fixedly connected to both sides of the load-bearing base to form an "H"-shaped base. The load-bearing base is loaded onto a modular transport vehicle through the load-sharing structures to transport the jacket structure upright.

[0006] Furthermore, the supporting prosthesis has the same diameter and wall thickness as the guide frame leg, and the supporting prosthesis is welded and fixed to the guide frame leg to become part of the guide frame leg.

[0007] Furthermore, the top cross-sectional shape of the supporting prosthetic leg matches the bottom cross-sectional shape of the guide frame leg for seamless welding; the length of the supporting prosthetic leg is customized according to the length and angle of each guide frame leg so that the supporting prosthetic leg and the guide frame leg are connected to form a figure-eight bend structure.

[0008] Furthermore, the reinforcing rib includes a first welded edge and a second welded edge that are perpendicular to each other. The first welded edge is welded to the supporting prosthetic leg, and the second welded edge is welded to the load-bearing base. A hollowed-out area is provided at the intersection of the first welded edge and the second welded edge. By cutting the reinforcing rib from the outside to the hollowed-out area, the supporting prosthetic leg can be separated from the load-bearing base.

[0009] Furthermore, one reinforcing rib is installed at 30° intervals, with 12 reinforcing ribs arranged around the perimeter of the prosthetic leg.

[0010] Furthermore, the load-bearing base includes an upper support plate and a lower support plate. The support prosthetic leg is fixed to the upper support plate by reinforcing ribs. Several vertical fixing ribs are welded between the upper and lower support plates for connection. Angled members are welded to the front and rear sides of the upper and lower support plates to form an "X" shaped structure. The load-sharing structure is welded to the left and right sides of the upper and lower support plates, and the load-sharing structure is also welded to the angled members.

[0011] Furthermore, the load-sharing structure includes an upper load-sharing plate and a lower load-sharing plate, which are welded and fixed together by several vertical connecting plates. One end of the beveled member and both ends of the fixing rib extend to the space between the upper load-sharing plate and the lower load-sharing plate and are welded and fixed together with the upper load-sharing plate, the lower load-sharing plate and the connecting plates.

[0012] The beneficial effects of this utility model are:

[0013] This device includes a load-bearing base, on which a supporting dummy leg is coaxially mounted. Several reinforcing ribs are symmetrically arranged around the supporting dummy leg. The top of the supporting dummy leg is fixedly connected to the jacket leg, and the bottom of the supporting dummy leg is fixedly connected to the load-bearing base via reinforcing ribs. Load-sharing structures are fixedly connected to both sides of the load-bearing base to form an "H"-shaped base. The load-bearing base is loaded onto a modular transport vehicle via the load-sharing structures for upright transport of the jacket. This device achieves high connection strength through the fixed connection of the supporting dummy leg and the jacket leg, combined with the reinforcing ribs. The "H"-shaped base also provides high strength, and one fixture can be loaded onto two transport vehicles simultaneously, distributing the weight of the jacket and meeting the needs of upright construction and transport of heavier four-legged jackets.

[0021] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "An Auxiliary Transportation Device for the Construction of a Jacket Stent" is provided in conjunction with the accompanying drawings.

[0022] See Figure 1 and Figure 2 In this embodiment, the auxiliary transportation device for the upright construction of the jacket includes a load-bearing base 100. A supporting leg 200 is coaxially arranged above the load-bearing base 100. Several reinforcing ribs 201 are evenly and symmetrically arranged around the supporting leg 200. The top of the supporting leg 200 is fixedly connected to the jacket leg, and the bottom of the supporting leg 200 is fixedly connected to the load-bearing base 100 through the reinforcing ribs 201. The reinforcing ribs 201 can effectively ensure the connection strength of the supporting leg 200. A load-sharing structure 300 is fixedly connected to both sides of the load-bearing base 100. The load-bearing base 100 and the load-sharing structure 300 form an "H"-shaped base, which improves the structural strength and lowers the overall center of gravity of the jacket, thereby improving the stability during transportation. The load-bearing base 100 is loaded on a modular transport vehicle through the load-sharing structure 300 to assist in the upright construction and transportation of the jacket. This device, by setting up a support leg 200 to connect with the jacket leg, and in conjunction with the reinforcing rib plate 201, effectively ensures the connection strength between the support leg 200 and the load-bearing base 100, as well as between the support leg 200 and the jacket leg. At the same time, the "H"-shaped base structure ensures the structural strength of the base and increases the contact area, so that one device can be mounted on two or more modular transport vehicles to meet the needs of vertical construction and transportation of jackets.

[0023] More specifically, in this embodiment, the diameter and wall thickness of the supporting prosthetic leg 200 are the same as those of the guide frame leg. This allows the supporting prosthetic leg 200 to become part of the guide frame leg after welding, improving connection strength. Furthermore, the top cross-sectional shape of the supporting prosthetic leg 200 matches the bottom cross-sectional shape of the guide frame leg, achieving seamless welding and a more stable connection. The length of the supporting prosthetic leg 200 is customized according to the length and angle of each guide frame leg, forming a figure-eight bend structure when connected to the guide frame leg. This ensures that the guide frame legs with the welded supporting prosthetic leg 200 are all on the same horizontal plane when upright, guaranteeing the stability of the center of gravity during upright transport of the guide frame.

[0024] See further Figure 1 In this embodiment, the reinforcing rib 201 includes a first welded edge 202 and a second welded edge 203 that are perpendicular to each other. The first welded edge 202 is welded to the supporting dummy leg 200, and the second welded edge 203 is welded to the load-bearing base 100. A hollowed-out area 204 is provided at the intersection of the first welded edge 202 and the second welded edge 203. By cutting the reinforcing rib 201 from the outside to the hollowed-out area 204, the supporting dummy leg 200 can be separated from the load-bearing base 100. In this way, when the jacket is transported to the designated location, only the reinforcing rib 201 needs to be cut to lift the jacket, which facilitates the separation operation. The supporting dummy leg 200 will become part of the jacket leg and be integrated into the overall structure of the jacket to provide support and fixation. The load-bearing base 100 and the load-bearing structure 300 can be recycled and reused, saving costs. Preferably, one reinforcing rib 201 is provided at 30° intervals, and 12 reinforcing ribs 201 are arranged around the periphery of the prosthetic leg 200 to ensure the connection stability between the prosthetic leg 200 and the load-bearing base 100.

[0025] See further Figure 2 In this embodiment, the load-bearing base 100 includes an upper support plate 101 and a lower support plate 102. The support prosthetic leg 200 is fixed to the upper support plate 101 by reinforcing ribs 201. Several vertical fixing ribs 103 are welded between the upper support plate 101 and the lower support plate 102 for connection. Angled members 104 are welded to the front and rear sides of the upper support plate 101 and the lower support plate 102 to form an "X" shaped structure, thereby improving the structural strength of the load-bearing base 100. The load-sharing structure 300 is welded to the left and right sides of the upper support plate 101 and the lower support plate 102, and the load-sharing structure 300 is also welded to the angled members 104, thereby improving the connection strength between the load-bearing base 100 and the load-sharing structure 300.

[0026] More specifically, in this embodiment, the load-sharing structure 300 includes an upper load-sharing plate 301 and a lower load-sharing plate 302. The upper load-sharing plate 301 and the lower load-sharing plate 302 are welded and fixed together by a plurality of vertical connecting plates 303. One end of the beveled member 104 and both ends of the fixing rib 103 extend to the space between the upper load-sharing plate 301 and the lower load-sharing plate 302 and are welded and fixed together with the upper load-sharing plate 301, the lower load-sharing plate 302 and the connecting plates 303, thereby further strengthening the connection strength between the load-bearing base 100 and the load-sharing structure 300 and improving the structural strength of the "H"-shaped base.
