Description

Technical Field

[0001] This invention belongs to the technical field of process equipment for electronic equipment assembly and testing, specifically relating to a multi-functional integrated device that enables modular assembly and disassembly in an outdoor environment and is used for vertical clamping, workstation transfer, and sealing testing of large-scale box-type electronic equipment. Background Technology

[0002] The large enclosure of a certain type of electronic equipment weighs approximately 3 tons and has dimensions of approximately 700mm × 2000mm × 6000mm, classifying it as a large-size, high-weight precision electronic device. During the equipment's life-cycle maintenance, it requires periodic upgrades and modifications under field conditions. The main process flow includes: disassembly → hoisting → vertical clamping → workstation transfer → disassembly → repair → assembly → sealing testing, involving the coordinated operation of multiple functional stages.

[0003] This large enclosure is a combination of an irregularly shaped frame and a skin, resulting in uneven structural rigidity and strict limitations on the clamping force surface: one side of the enclosure houses the antenna unit, a precision structure that cannot withstand clamping forces; the other side is the enclosure door, which must maintain accessibility. These structural characteristics render traditional symmetrical clamping methods unsuitable, and the enclosure's center of gravity is offset, leading to a significant overturning moment in vertical clamping, highlighting the need for anti-overturning measures.

[0004] In existing technologies, vertical clamping of large equipment typically employs specialized vertical tooling. A typical solution involves setting fixed supports on both sides of the workpiece to be clamped, applying symmetrical clamping forces through bolts or clamping mechanisms, and securing it to the factory floor with anchor bolts to ensure clamping stability. While this solution meets the basic requirements for vertical clamping within the workshop, it has the following drawbacks: First, the tooling is a fixed, bulky structure that cannot be disassembled, making it unsuitable for off-site transport. Second, the tooling relies on a fixed foundation, making it unsuitable for uneven off-site conditions. Third, the tooling has a limited function, only capable of clamping and fixing; subsequent processes such as workstation transport and sealing testing still require separate specialized equipment, posing operational risks associated with multiple lifting and transport operations.

[0005] For workstation transfer of large equipment, existing technologies typically employ wheeled transfer trolleys or hydraulic transfer platforms to move the workpiece from one workstation to another. For sealing testing, existing technologies typically use independent pressurized testing benches, connecting the cavity to be tested via dedicated sealing joints. These solutions all involve separate, dedicated devices with independent functions, making it impossible to integrate vertical clamping, workstation transfer, and sealing testing on a single platform. Furthermore, in field conditions, the coordinated transportation, deployment, and connection of multiple independent devices further increases process complexity and safety risks.

[0006] In summary, existing technologies lack an integrated device that simultaneously meets all of the following technical requirements: modular assembly and disassembly to adapt to field transportation conditions; safe vertical clamping and anti-tipping fixation for irregularly shaped large boxes with offset centers of gravity; convenient transfer between indoor and outdoor workstations; and flexible sealing detection capabilities adaptable to different box interfaces. Therefore, there is an urgent need to develop a multifunctional integrated modular device to meet the practical needs of large box assembly operations under the aforementioned field conditions. Summary of the Invention

[0007] The technical problem to be solved by this invention is: when upgrading and modifying large-scale enclosure electronic equipment under field conditions, there is a lack of multi-functional integrated devices that can simultaneously realize vertical clamping, workstation transfer and sealing detection. The invention provides a multi-functional integrated modular device for enclosure assembly that can be assembled and disassembled in modular fashion and is adaptable to field conditions.

[0008] To address the aforementioned technical problems, this invention provides a multifunctional integrated modular device for assembling boxes, comprising a modular frame assembly, a leveling support system, an anti-tipping system, and distributed rollers.

[0009] The modular frame assembly consists of several square-box welded skeletons connected by bolts to form an "I"-shaped planar frame, enabling modular assembly and disassembly for easy transportation and handling. Within the "I"-shaped planar frame, several square-box welded skeletons are arranged laterally to form upper and lower crossbeams, with a web between them. Several limiting blocks and metal sleepers are installed on the square-box welded skeletons, their positions determined by the stability of the box structure.

[0010] The leveling support system is installed at the bottom of the modular frame assembly and includes several adjustable leveling support legs. Each adjustable leveling support leg includes a screw and a foot cup. One end of the screw is connected to the bottom of the modular frame assembly, and the other end is connected to the foot cup. The extension length of the support leg can be adjusted by rotating the screw to adapt to uneven ground conditions.

[0011] The anti-tipping system is mounted on a modular frame assembly and includes adjustable outriggers and an adjustable cable mechanism. The adjustable outriggers consist of an adjusting screw and a support flange. One end of the adjusting screw is connected to a triangular bracket on the modular frame assembly, and the other end is connected to the support flange. The adjustable cable mechanism consists of a hook, a cable, and a locking mechanism. The hook is attached to the housing, and one end of the cable is connected to the hook; the other end is fixed to the square box-type welded frame via the locking mechanism. The adjustable outriggers and the adjustable cable mechanism are located on the same side of the housing. The adjustable outriggers apply a supporting force to the side of the housing along the supporting direction, while the adjustable cable mechanism applies a pulling force to the side of the housing along the diagonal pulling direction, forming a bidirectional fixation on the same side, effectively preventing the housing from tipping over.

[0012] The distributed rollers are installed at the bottom of the modular frame assembly, comprising a plurality of rollers uniformly distributed at the bottom of the frame. Each roller is mounted on a roller mounting plate, enabling transfer and transportation between indoor and outdoor workstations.

[0013] The present invention further comprises a combined sealing detection device arranged on the modular frame assembly. The combined sealing detection device includes a replaceable joint, a hose, a two-way valve block, a pressure reducing valve, a pressure gauge and a gas source. The gas source is sequentially connected to the replaceable joint through the hose, the pressure reducing valve and the two-way valve block, and is connected to the system to be detected. The pressure gauge is connected to the two-way valve block, and the two-way valve block is fixed on the modular frame assembly, so as to realize flexible sealing detection.

[0014] Adopting the technical solution of the present invention, compared with the prior art, the following beneficial effects are obtained: (1) The modular frame assembly is assembled by connecting a plurality of small square-box welding frameworks through bolts, which can realize modular disassembly and assembly, is convenient for transportation and turnover, and adapts to outfield conditions.

[0015] (2) The leveling support system adopts leveling-adjustable support legs, which can adapt to uneven ground conditions and ensure the horizontal accuracy of large箱体 during vertical clamping.

[0016] (3) The anti-overturning system adopts a same-side two-way fixing mode of adjustable support arms and an adjustable cable mechanism, where the support and the diagonal cable bear force in two directions, effectively resisting the overturning moment and ensuring the safety of vertical clamping of large箱体.

[0017] (4) The distributed rollers realize transfer and transportation between indoor and outdoor workstations, breaking through the limitation of outfield conditions.

[0018] (5) The combined sealing detection device adopts replaceable joints and combined pipelines, realizing flexible sealing detection for different箱体. Description of Drawings

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this invention provides a multifunctional integrated modular device for assembling a housing 18, including an anti-tipping system 1, distributed rollers 2, a modular frame assembly 3, and a leveling support system 5. The modular frame assembly 3 serves as the mounting platform for the entire device. The leveling support system 5 and the distributed rollers 2 are installed at the bottom of the modular frame assembly 3, and the anti-tipping system 1 is mounted on the modular frame assembly 3. This invention also includes a combined sealing detection device 4.

[0023] I. Modular Frame Assembly like Figure 2 As shown, the modular frame assembly 3 consists of several square box-shaped welded skeletons 6, triangular supports 16, limiting blocks 7, and metal sleepers 8. The square box-shaped welded skeletons 6 are arranged laterally to form upper and lower crossbeams, with a web between them. The triangular supports 16 connect the upper and lower crossbeams, collectively assembling an "I"-shaped planar frame. Limiting blocks 7 are located on the upper surfaces of the upper and lower crossbeams to position the box 18. Metal sleepers 8 connect the square box-shaped welded skeletons 6, their installation positions determined by the stable position of the box 18, serving both positioning support and overall reinforcement functions. All components are bolted together, allowing for modular assembly and disassembly, facilitating transportation and handling, and adapting to field conditions.

[0024] II. Leveling Support System The leveling support system 5 is installed at the bottom of the modular frame assembly 3 and includes twelve adjustable leveling support legs. Each adjustable leveling support leg consists of a screw 9 and a foot cup 10. One end of the screw 9 is connected to the bottom of the modular frame assembly 3, and the other end is connected to the foot cup 10. By rotating the screw 9, the extension length of the support leg is adjusted to achieve overall leveling of the frame, adapt to uneven ground conditions, and ensure the horizontal accuracy of the box 18 when it is vertically clamped.

[0025] III. Anti-overturning system like Figure 3As shown, the anti-tipping system 1 includes an adjustable outrigger and an adjustable cable mechanism. The adjustable outrigger consists of an adjusting screw 13 and a support flange 12. One end of the adjusting screw 13 is connected to a triangular bracket 16 on the modular frame assembly 3, and the other end is connected to the support flange 12. The extension distance of the support flange 12 is adjusted by rotating the adjusting screw 13, so that the support flange 12 abuts against the side of the box body 18. The adjustable cable mechanism consists of a hook 14, a cable 15, and a locking mechanism 17. The hook 14 is hung on the box body 18, and one end of the cable 15 is connected to the hook 14, while the other end is fixed to the square box-type welded frame 6 by the locking mechanism 17.

[0026] The adjustable support arm and the adjustable cable mechanism are located on the same side of the housing 18. The adjustable support arm applies a supporting force to the side of the housing 18 along the supporting direction, and the adjustable cable mechanism applies a pulling force to the side of the housing 18 along the diagonal pulling direction, forming a two-way fixation of "support and diagonal pulling" on the same side, effectively resisting the overturning moment and ensuring the safe and reliable vertical clamping of the housing 18.

[0027] IV. Distributed Rollers The distributed rollers 2 are installed at the bottom of the modular frame assembly 3, and include six rollers 11 evenly distributed at the bottom of the frame. Each roller 11 is mounted on a roller 11 mounting plate, and the load-bearing capacity of a single roller 11 is not less than 1500 kg. The distributed rollers 2 enable the transfer and transportation of the device between indoor and outdoor workstations, overcoming the limitations of outdoor conditions.

[0028] V. Combined Sealing Detection Device like Figure 4 As shown, the present invention also includes a combined sealing detection device 4. The combined sealing detection device 4 includes a replaceable connector 19, a hose 20, a two-way valve block 21, a pressure reducing valve 22, a pressure gauge 23, and a gas source 24. The gas source 24 uses a nitrogen cylinder, which is connected to the replaceable connector 19 sequentially via the hose 20, the pressure reducing valve 22, and the two-way valve block 21. The pressure gauge 23 is connected to the two-way valve block 21. The output pressure is adjusted by the pressure reducing valve 22, and the gas path is controlled by the two-way valve block 21. The gas is connected to the detection interface of the housing 18 via the replaceable connector 19, and the pressure gauge 23 displays the detection pressure in real time. The replaceable connector 19 can be replaced according to the detection interface of different housings 18, realizing flexible sealing detection. The two-way valve block 21 is fixed on the modular frame assembly 3.

[0029] The working process of this invention is as follows: First, the components of the modular frame assembly 3 are transported to the field and assembled into an "I"-shaped planar frame using bolts. Then, the frame is leveled using the leveling support system 5 to ensure horizontal accuracy. The housing 18 is hoisted onto the frame, positioned using the limit block 7, and the anti-tipping system 1 is activated. The adjustable support flange 12 is adjusted to abut against the side of the housing 18, and the hook 14 of the adjustable cable mechanism is attached and locked, forming a bidirectional fixation on the same side. When relocation is required, the leveling support system 5 is retracted, and the device and housing 18 are transported together to the target workstation using distributed rollers 2. After assembly, the housing 18 is tested for sealing performance using the combined sealing detection device 4 to confirm that the sealing performance of the housing 18 is qualified.
