Description

Technical Field

[0001] This utility model relates to the field of modular device technology, and in particular to a steel structure base and modular equipment. Background Technology

[0002] Modularization, as an advanced modern engineering concept and technology, has gained popularity among engineering companies and construction units in recent years, and its application in the construction of nuclear engineering research facilities is becoming increasingly widespread. Similar to skid-mounted modules in the petroleum and chemical industries, nuclear engineering research facility modules assemble one or more items such as equipment, pipelines, valves, instruments, ducts, and cable trays within the design area into a single steel structure frame, forming an organic whole. The steel structure provides support for each component and / or provides a base for the equipment. For nuclear research facility projects constructed off-site, due to limitations in site environment or space conditions, modules are generally installed in a factory, assembled, and then transported as a whole to the construction site.

[0003] Modular transportation typically involves long distances and numerous hoisting and transfer operations. Therefore, modular transportation requires careful consideration of a base that allows for convenient and quick movement of the entire unit, facilitating transportation and hoisting. However, existing bases often only support a single function during transportation. This single-function base significantly increases the transportation time, costs, and safety risks associated with modular devices, which is highly detrimental to urgent construction tasks.

[0004] Therefore, this application provides a new steel structure base and modular equipment to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure base to at least alleviate the technical problem of the limited transportation function of steel structure bases in the prior art.

[0006] The purpose of this utility model is also to provide a modular device to further alleviate the technical problem of the single transportation function of the steel structure base in the prior art.

[0007] Based on the aforementioned first objective, this utility model provides a steel structure base, which includes a main frame and a reinforcing frame disposed within the main frame;

[0008] The main frame is provided with lifting lugs, and the main frame has two forklift holes corresponding to the two forks of the forklift. Along the center direction of the forklift holes, the forklift holes penetrate the main frame and the reinforcing frame to form a forklift passage.

[0009] Furthermore, the forklift hole is a tapered hole, and the diameter of the tapered hole gradually decreases from the outside to the inside.

[0010] Furthermore, the main frame includes multiple main beams that are connected end to end in sequence, and the reinforcing frame is connected to the main beams;

[0011] The lifting lugs are disposed between adjacent main beams, and the forklift hole is opened in the main beam along the center direction of the forklift hole. The forklift hole penetrates the main beam and the reinforcing frame to form the forklift passage.

[0012] Furthermore, the main frame includes four main beams, which are connected end to end to form a quadrilateral shape. The four main beams are two main horizontal beams and two main longitudinal beams arranged opposite each other.

[0013] Furthermore, the main crossbeam and the main longitudinal beam are provided with connection holes for detachable connection with the modular device.

[0014] Furthermore, the main crossbeam and the main longitudinal beam are provided with fixing holes for connecting to the ground.

[0015] Furthermore, both the main crossbeam and the main longitudinal beam are made of channel steel of the same specifications, and the material of the channel steel is Q235B.

[0016] Furthermore, the reinforcing frame includes a plurality of secondary longitudinal beams connected between the two main longitudinal beams and a plurality of secondary transverse beams connected between the two main longitudinal beams.

[0017] Furthermore, the plurality of secondary longitudinal beams are spaced apart along the length direction of the main transverse beam, and the plurality of secondary transverse beams are spaced apart along the length direction of the main longitudinal beam.

[0018] By adopting the above technical solution, the steel structure base of this utility model has at least the following beneficial effects:

[0019] It should be added that conventional bases can only be lifted and transported using a single hoisting device or a forklift. To address these issues, the steel structure base in this embodiment utilizes lifting lugs on the main frame to allow for hoisting by a crane and forklift access to facilitate transport by forklift. This diversifies the transport functionality of the steel structure base, alleviating the problem of limited transport capabilities in existing technologies.

[0037] Please see Figure 1 and Figure 2 This embodiment provides a steel structure base, which includes a main frame 1 and a reinforcing frame 2 disposed within the main frame 1; the main frame 1 is provided with lifting lugs 3, and the main frame 1 is provided with two forklift holes 41 corresponding to the two forks of a forklift. Along the center direction of the forklift holes 41, the forklift holes 41 penetrate the main frame 1 and the reinforcing frame 2 to form a forklift passage 42.

[0038] It should be noted that the main frame 1 determines the shape and size of the entire steel structure base. The shape and size of the main frame 1 are consistent with the shape and size of the outer frame or base plate of the modular device to be supported, so that the load of the modular device can be evenly distributed on the entire base.

[0039] In addition, the forklift aisle 42 is designed according to the size of the forklift's fork arm, and should allow for normal passage of the fork arm with a certain margin. For example, the width of the forklift aisle 42 is 200mm. The spacing between the two forklift aisles 42 is designed according to the spacing between the two forklift arms. For example, the center-to-center spacing between the two forklift aisles 42 is 1080mm.

[0040] It should be added that conventional bases can only be lifted and transported using a single hoisting device or a forklift. To address these issues, the steel structure base in this embodiment utilizes lifting lugs 3 on the main frame 1, enabling it to be lifted and transported using a crane, and also utilizes forklift access channels 42 on the steel structure base, allowing it to be transported using a forklift. This diversifies the transport functionality of the steel structure base, alleviating the technical problem of limited transport functionality in existing technologies.

[0041] In summary, the steel structure base of this embodiment not only meets the needs of hoisting and transporting modular devices, optimizes the transportation and installation of modular devices, shortens construction time, and reduces construction costs, but also can be used as a base for modular devices for a long time, solving the problem of difficult overall replacement, maintenance, and dismantling of modular devices.

[0042] Preferably, please refer to Figure 2 In this embodiment, the forklift hole 41 is a conical hole, and the diameter of the conical hole gradually decreases from the outside to the inside.

[0043] This design, with a larger external diameter forklift hole 41, provides guidance for the insertion of the forklift's fork arm, facilitating its smooth insertion into the forklift channel 42. For example, please refer to... Figure 2 In this embodiment, the forklift hole 41 is a frustum, and the smaller end face of the frustum is located further inward.

[0044] Preferably, please refer to Figure 1 and Figure 2 In this embodiment, the main frame 1 includes multiple main beams connected end-to-end, and the reinforcing frame 2 is connected to the main beams; wherein, please refer to Figure 3 The lifting lug 3 is set between adjacent main beams, and the forklift hole 41 is opened in the main beam. Along the center direction of the forklift hole 41, the forklift hole 41 passes through the main beam and the reinforcing frame 2 to form a forklift passage 42.

[0045] For example, the main frame 1 includes four main beams, which are connected end to end to form a quadrilateral; or the main frame 1 includes five main beams, which are connected end to end to form a pentagon; or the main frame 1 includes six main beams, which are connected end to end to form a hexagon; or the main frame 1 includes multiple main beams, which are connected end to end to form a circle, etc.

[0046] Preferably, please refer to Figure 2 In this embodiment, the main frame 1 includes four main beams, which are connected end to end to make the main frame 1 a quadrilateral. The four main beams are two main horizontal beams 11 and two main vertical beams 12 that are arranged opposite each other.

[0047] In other words, four lifting lugs 3 are provided, each located in one of the four main beams, between adjacent main beams. This arrangement serves two purposes: firstly, it facilitates lifting operations by the crane, and secondly, it connects adjacent main beams. For example, please refer to... Figure 3 The lifting lug 3 is made of 100mm*100mm Q235B square steel. The length of the square steel is the same as the height of the main beam steel section. There are two lifting lug 3 holes on the lifting lug 3, and the hole size is φ20mm.

[0048] Preferably, in this embodiment, the length of the main crossbeam 11 does not exceed 13m, and the length of the main longitudinal beam 12 does not exceed 3.5m, so as to ensure that the land transportation of the base does not exceed the size requirements of the items that the vehicle is allowed to load.

[0049] Preferably, please refer to Figure 1 and Figure 2 In this embodiment, the main crossbeam 11 and the main longitudinal beam 12 are provided with connection holes 13 for detachable connection with the modular device.

[0050] Optionally, the main crossbeam 11 has multiple connecting holes 13, which are spaced apart on the main crossbeam 11; preferably, in this embodiment, the multiple connecting holes 13 are evenly distributed on the main crossbeam 11. Optionally, the main longitudinal beam 12 has multiple connecting holes 13, which are spaced apart on the main longitudinal beam 12; preferably, in this embodiment, the multiple connecting holes 13 are evenly distributed on the main longitudinal beam 12.

[0051] For example, the connecting hole 13 is an oblong hole with dimensions of 38mm*9mm. The spacing between adjacent connecting holes 13 is 400mm except at the forklift aisle 42 entrance / exit positions, where the spacing can be set to 200mm at other positions.

[0052] Preferably, please refer to Figure 1 In this embodiment, the main crossbeam 11 and the main longitudinal beam 12 are provided with fixing holes 14 for connecting to the ground.

[0053] Optionally, the main crossbeam 11 has multiple fixing holes 14, which are spaced apart on the main crossbeam 11; preferably, in this embodiment, the multiple fixing holes 14 are evenly distributed on the main crossbeam 11. Optionally, the main longitudinal beam 12 has multiple fixing holes 14, which are spaced apart on the main longitudinal beam 12; preferably, in this embodiment, the multiple fixing holes 14 are evenly distributed on the main longitudinal beam 12.

[0054] For example, the fixing hole 14 is an oblong hole with a size of 3mm8*9mm. Bolts or expansion bolts are inserted into the fixing hole 14 to connect the main crossbeam 11 and the main longitudinal beam 12 to the ground. The spacing and hole size can be determined by calculation based on the total load of the device.

[0055] Preferably, in this embodiment, the main crossbeam 11 and the main longitudinal beam 12 are both channel steels of the same specification, and the material of the channel steel is Q235B. For example, the channel steel specifications of the main crossbeam 11 and the main longitudinal beam 12 can be 10#, 12# or 14#.

[0056] Preferably, please refer to Figure 1 and Figure 2 In this embodiment, the reinforcing frame 2 includes a plurality of secondary longitudinal beams 21 connected between two main longitudinal beams 11 and a plurality of secondary longitudinal beams 22 connected between two main longitudinal beams 12.

[0057] The structural strength of the steel structure base is improved by supporting the two main crossbeams 11 with multiple secondary longitudinal beams 21 and supporting the two main longitudinal beams 12 with multiple secondary crossbeams 22.

[0058] Preferably, please refer to Figure 2 In this embodiment, multiple secondary longitudinal beams 21 are spaced apart along the length direction of the main transverse beam 11, and multiple secondary transverse beams 22 are spaced apart along the length direction of the main longitudinal beam 12.

[0059] Optionally, the spacing between adjacent secondary longitudinal beams 21 can be 300mm-500mm, and the spacing between adjacent secondary transverse beams 22 can be 300mm-500mm. For example, the spacing between adjacent secondary longitudinal beams 21 can be 300mm, 350mm, 400mm, 450mm or 500mm, and the spacing between adjacent secondary transverse beams 22 can be 300mm, 350mm, 400mm, 450mm or 500mm, etc.

[0060] It should be noted that the secondary longitudinal beam 21 and secondary transverse beam 22 should be disconnected when they pass through the forklift passage 42. The secondary longitudinal beam 21 and the main transverse beam 11, the secondary transverse beam 22 and the main longitudinal beam 12, and the contact points of the channel steel of the forklift passage 42 should all be fully welded to ensure the strength of the entire steel structure base.

[0061] In summary, the steel structure base of this embodiment can not only be used for the transportation of experimental devices in various research institutions in China, but can also be widely promoted to modular installation in the construction industry.

[0062] The base uses mature materials and accessories, featuring a simple structural design, low cost, and convenient and quick manufacturing and installation. Cranes and forklifts can be used independently or in conjunction, overcoming the limitations of traditional bases and achieving a "multi-purpose" effect.
