Description

Technical Field

[0001] The utility model relates to the technical field of booster stations, and particularly relates to a combined tool for roll-on / roll-off transportation and lashing of a large booster station. Background Art

[0002] A large offshore electrical module with the structure and electrical system of the booster station as the main body and specialties such as iron fitting, HVAC, fire protection, and service water as the auxiliary. Its construction involves multiple specialties, has a short construction period, and high construction requirements. Through the accumulation of construction experience in many previous booster station projects, the company has fully grasped the characteristics of booster station construction. Combining with the implementation requirements of "modular construction and no open fire after painting" vigorously promoted within the company at present, based on saving project construction costs, ensuring project duration, and creating high-quality project works, the company implements the modular general assembly and lightering technology of the booster station.

[0003] Due to the large volume and weight of the booster station reaching thousands of tons, and there is a height difference of 3 - 4 meters between the four main legs and the bottom structure, the requirements for the height and load-bearing capacity of the transfer jig are very high. The commonly used gantry shelf can no longer meet the needs. Usually, a transfer bracket needs to be preset at the bottom of the structure. The transfer bracket is a cuboid truss structure, with a large volume, high manufacturing cost, and few applicable products for the bracket. When the bracket is not in use, it basically causes inventory backlog. When using the bracket to cooperate with the modular vehicle to transfer and ship it, after the four main legs are placed on the deck, the bracket still needs to be withdrawn together with the modular vehicle, and then the internal bracing and lashing operations are carried out. This not only costs a large amount of materials and labor costs, but also a large number of lashing operations affect the shipping cycle. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a combined tool for roll-on / roll-off transportation and lashing of a large booster station with low manufacturing cost, high utilization rate, and after being transported to the transport ship, the bracket is withdrawn together with the modular vehicle without a large number of lashing operations.

[0005] To solve the above technical problem, the technical solution of the utility model is: a combined tool for roll-on / roll-off transportation and lashing of a large booster station, and its innovation lies in: including a double-layer frame structure, the double-layer frame structure includes a lower-layer gantry group and an upper-layer gantry group;

[0006] The lower-layer gantry group includes two first gantry shelves symmetrically arranged on the ground, and the top between the two first gantry shelves is connected by horizontal first profiled steels on both sides and in the middle. Then, the first profiled steel and the two first gantry shelves form a lower-layer accommodation area, making the lower-layer gantry group form a structure in the shape of a Chinese character "ri";

[0007] The upper gantry group includes two second gantry shelves symmetrically arranged on the top of the lower gantry group and respectively located on the tops of two first gantry shelves. The tops between the two second gantry shelves are also connected by horizontal second steel sections on both sides and in the middle, so that the upper gantry group forms a rectangular structure. Then, the second steel section and the two second gantry shelves form an upper accommodation area.

[0008] The first gantry shelf and the second gantry shelf have the same structure, and a single gantry shelf can carry 150T. This tooling is composed of 4 gantry shelves, which not only increases the stability of the load-bearing but also adapts to the height requirement problem of the 4 main legs of the lifting station construction jig extending down to the bottom structure.

[0009] Furthermore, both the first steel section and the second steel section are H-shaped steel, which enhances the stability of the frame clamp structure.

[0010] Furthermore, support legs are installed inside the lower gantry group between the two first gantry shelves, which can further increase the load-bearing and force transmission.

[0011] Furthermore, there are also vertical strengthening support columns. A first vertical strengthening support column is installed at the middle position between the first steel section and the second steel section on the upper gantry group. A second vertical strengthening support column is installed vertically below the first vertical strengthening support column at the bottom of the first steel section of the lower gantry group. The second vertical strengthening support column and the first vertical strengthening support column are aligned to ensure the force transmission and enhance the load-bearing area of this structure on the ground.

[0012] Furthermore, the upper gantry group also includes diagonal strengthening support columns. One diagonal strengthening support column is installed on both sides of the first vertical strengthening support column between the first steel section and the second steel section, and the diagonal strengthening support column is also HW350 H-shaped steel, which enhances the structural stability of this structure.

[0013] Furthermore, corresponding stiffening rib plates are provided at the corresponding positions of the first steel section and the second steel section inside the diagonal strengthening support columns, which enhances the structural stability of this structure.

[0014] The advantages of the present utility model are as follows:

[0015] 1. This tooling is made by reforming the existing gantry shelves within the company. It has a simple structure, saves material consumption, has a low manufacturing cost, a high utilization rate, and speeds up the tooling manufacturing cycle.

[0016] 2. This tooling can also be applied to other projects when not in use. Even if not applicable, it can be disassembled back into gantry shelves, reducing the disassembly workload.

[0017] 3. When the tooling is transferred to the ship with the module vehicle, it is not removed with the module vehicle and is directly used as a lashing tooling, which saves lashing tooling materials and lashing workload, shortens the shipping cycle and ensures project delivery.

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4 The large-scale booster station roll-on / roll-off transport and binding dual-purpose tool shown includes a double-layer frame structure. This tool is modified by the existing gantry shelf within the company. It has a simple structure, saves materials, has low production costs, high utilization rate, and speeds up the tool production cycle.

[0024] Moreover, since the load-bearing capacity of the gantry shelf has been calculated during normal use and the load-bearing capacity is obtained, and this tooling is modified on the basis of the gantry shelf, the calculation of the load-bearing capacity can be avoided.

[0025] The double-layer frame structure includes a lower gantry group 1, an upper gantry group 2 and vertical reinforcement support columns 3.

[0026] The lower gantry group 1 includes two first gantry shelves 11 symmetrically arranged on the ground, and the tops of the two first gantry shelves 11 on both sides and in the center are connected by horizontal first steel sections 12, so that the lower gantry group 1 forms a Japanese-shaped structure, and the first steel section 12 and the two first gantry shelves 11 form a lower accommodating area.

[0027] Support legs 13 are further installed on the inner sides of the two first gantry shelves 11 of the lower gantry assembly 1, thereby increasing the load-bearing capacity and force transmission.

[0028] The upper gantry group 2 includes two second gantry shelves 21 symmetrically arranged on the top of the lower gantry group 1 and respectively located on the top of the two first gantry shelves 11, and the tops of the two second gantry shelves 21 on both sides and the center are also connected by horizontal second steel sections 22, so that the upper gantry group 2 forms a Japanese-shaped structure, and the second steel sections 22 and the two second gantry shelves 21 form an upper accommodating area.

[0029] All the steel sections in this embodiment are HW350 steel sections.

[0030] The first gantry shelf 11 and the second gantry shelf 21 have the same structure, and a single gantry shelf can carry 150T. The four gantry shelves are used to form this tooling, which increases the stability of the load while adapting to the height requirement of the four main legs of the frame of the booster station 5 extending down to the underlying structure.

[0031] The first steel section 12 and the second steel section 22 are both H-shaped steel sections, which enhance the stability of the frame-clamp structure.

[0032] A first vertical reinforcing support column 31 is installed on the upper gantry assembly 2 at a middle position between the first section steel 12 and the second section steel 22 .

[0033] The bottom of the first steel section 22 of the lower gantry group 1 is located vertically below the first vertical reinforcing support column 31, and a second vertical reinforcing support column 32 is installed. The second vertical reinforcing support column 32 and the first vertical reinforcing support column 31 are reinforced to ensure the transmission of force and enhance the bearing area of ​​the structure on the ground. The second vertical reinforcing support column 32 divides the lower accommodating area into two parts, each of which can accommodate a module car to extend into, thereby not affecting the entry of cars on both sides of the second vertical reinforcing support column 32.

[0034] The second vertical reinforcing support column 32 and the support leg 13 in this structure are added in consideration of the higher stability requirement for the lower gantry frame group when the gantry shelves are stacked, which can increase the ground bearing area and ensure the transmission of structural force.

[0035] The upper gantry group 2 also includes an oblique reinforcing support column 23. An oblique reinforcing support column 23 is installed on both sides of the first vertical reinforcing support column 31 between the first steel section 12 and the second steel section 22, and the oblique reinforcing support column 23 is also an H-shaped steel of HW350, which enhances the structural stability of this structure.

[0036] Corresponding reinforcing ribs 4 are provided inside the first section steel 12 and the second section steel 22 at positions corresponding to the oblique reinforcing support columns 23, thereby enhancing the structural stability of the structure.

[0037] This tooling can also be used for other projects when not in use. Even if it is not used, it can be disassembled back to the gantry shelf to reduce the workload of disassembly.

[0038] Working principle of this patent:

[0039] Before construction, 8 sets of this tooling are pre-set in two rows and four columns at the corresponding positions at the bottom of the booster station 5 to serve as a construction frame. The lower ends of the four main legs are padded with pad beams 6. For the middle structure, a temporary closing support frame 7 can be added between the two rows of this tooling.

[0040] After the structure is built, four groups of module vehicles A / B / C / D enter from the bottom of the tooling, and then are lifted up for transportation. The added temporary closure support cradle 7 is not taken away with the structure during transportation. When the booster station 5 is transferred to the transport ship, the four main legs are also placed on the cushion beam 6, the transfer cradle is placed on the deck, and then the vehicle is withdrawn.

[0041] At this time, this tooling also serves as the shipping and lashing tooling, eliminating the need for additional support lashing work at the bottom of the structure, shortening the shipping cycle and ensuring project delivery.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
