[0025] Combined with appendix Figure 1 This invention discloses a modular steel structure combined test platform, comprising: an upper compartment 1, a middle compartment 2, a lower compartment 3, a mounting base 4, and an operating ladder 5; the upper compartment 1, middle compartment 2, and lower compartment 3 are arranged from top to bottom. The bottom of the frame of the upper compartment 1 is bolted to the top of the frame of the middle compartment 2, the bottom of the frame of the middle compartment 2 is bolted to the top of the frame of the lower compartment 3, the bottom of the frame of the lower compartment 3 is bolted to the mounting base 4, the lower operating platform 5-2 of the operating ladder 5 is bolted to the mounting base 4, and the upper operating platform 5-1 is bolted to the lower operating platform 5-2 and then bolted to the frame of the middle compartment 2. This invention is versatile and can adapt to the installation requirements of phased array antenna arrays of different specifications within a certain size range.

[0026] Combined with appendix Figure 1 , Figure 2 , Figure 11The upper compartment 1 is composed of upper lifting lugs 1-1, upper frame 1-2, upper compartment equipment installation interface plate 1-3, upper compartment antenna cover 1-4, first floor 1-5, upper compartment outer skin 1-6, and upper compartment door 1-7.

[0027] Combined with appendix Figure 1 , Figure 3 , Figure 11 The middle compartment 2 consists of a middle frame 2-1, a middle compartment equipment installation interface plate 2-2, a middle compartment antenna cover 2-3, a second floor 2-4, a middle compartment outer skin 2-5, and a door 2-6.

[0028] The upper compartment equipment installation interface plate 1-3 and the middle compartment equipment installation interface plate 2-2 can be easily replaced, and array equipment of different sizes can be connected to the corresponding installation interface plate.

[0029] Combined with appendix Figure 1 , Figure 4 , Figure 11 The lower compartment 3 is composed of a frame 3-1, a third floor 3-2, an outer skin 3-3, and a lower compartment door 3-4.

[0030] Combined with appendix Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 The independent modules in the test platform are welded together. The upper frame 1-2, middle frame 2-1, frame 3-1, and mounting base 4 are all welded using standard profiles, with internal reinforcing ribs to increase structural strength. The outer skin of the frame and the floor are made of thin steel plate. To achieve waterproofing, the overlaps between the skins are fully welded.

[0031] Combined with appendix Figure 1 , Figure 5 , Figure 6 , Figure 11 The compartments are connected by bolts. The top mounting area 2-1-1 of the middle compartment frame coincides with the bottom opening area of ​​the upper compartment frame, and the bottom mounting area 2-1-2 of the middle compartment frame coincides with the top mounting area of ​​the lower compartment frame. The bottom mounting area of ​​the lower compartment frame is connected to the mounting base 4. The area connecting each compartment is the main load-bearing support area within the frame, with high strength, increasing the safety and stability between the compartments. The compartment connection area makes full use of the external frame's tilt angle to form an effective rainproof distance.

[0032] Combined with appendix Figure 5, the installation base 4 is formed by welding standard profiles. The reinforcing ribs are welded in a large-span "rice" shape to enhance the strength of the overall base.

The lower operation platform 5-2 is fixed to the installation base 4 by bolts. After the upper operation platform 5-1 is fixed to the lower operation platform 5-2 by bolts, the upper operation platform 5-1 is then fixed to the middle cabin 2 by bolts. The stair treads of the operation platform are welded with patterned steel plates to increase friction. After the upper and lower operation platforms are connected, the fences are welded, and the fences are made of bent steel pipes welded.

[0034] Combined with attached Figure 10 , attached Figure 11 , the equipment installation interface board 1-3 is fixed to the front frame of the upper cabin 1 by screws. The equipment installation interface board 1-3 of the upper cabin is integrally formed by welding steel plates and profiles to ensure that the phased array antenna is coplanar with the test platform surface.

[0035] Combined with attached Figure 11 , the main installation process of the modular steel structure combined test platform in practical application is as follows:

[0036] 1. First, fix the installation base 4 to the ground of the installation site. It can be fixed by driving expansion screws into the reinforced ground or welding the bottom frame to the deck.

[0037] 2. Connect and fix the lower cabin 3 to the installation base 4 by bolts, and then connect the middle cabin 2 to the lower cabin 3 by bolts.

[0038] 3. At this time, for the convenience of the installation personnel to operate, fix the lower operation platform 5-2 to the installation base 4 by bolts, and then fix the upper operation platform 5-1 to the middle cabin 2 by bolts.

[0039] 4. Then, fix the upper cabin 1 to the middle cabin 2 by bolts.

[0040] 5. After the main structure of the test platform is installed, apply structural sealant at the joints between the cabins.

[0041] 6. Connect the upper cabin equipment installation interface board 1-3 to the front frame of the upper cabin by screws.

[0042] 7. Install the phased array antenna panel equipment 6 on the upper cabin equipment installation interface board 1-3 through the equipment hoisting tooling 7, and finally fix the radome 1-4 to the test platform.

[0043] The modular steel structure combined test platform of the present invention has now been assembled and is ready for testing.

[0044] Instructions for use: The antenna array device 6 to be installed in the upper compartment 1 is hoisted to the mounting interface plate 1-3 in the upper compartment using the hoisting fixture 7. The antenna array device 6 is then connected and secured to the upper compartment equipment mounting interface plate 1-3 using fasteners. Finally, the radome 1-4 is installed in the upper compartment 1 to form a seal. For phased array antenna array devices of different frequency bands or different installation sizes, installation can be carried out in compartments of different heights by selecting the corresponding equipment mounting interface plate.
