[0045] The specific implementation is that: when the module structure is tested, first, the module structure is installed and positioned, after installation and positioning, testing is performed, the hydraulic module 61 is started, the hydraulic module 61 drives the extrusion plate 64 to move downward, the extrusion plate 64 contacts the upper surface of the module structure and continuously applies pressure downward, as the pressure increases, the module structure deforms, and at the same time, the extrusion plate 64 can drive the walking assembly 10 to move downward synchronously, when the first stage test is completed, the extrusion plate 64 is driven again to drive the walking assembly 10 to reset, and secondary extrusion is performed again, in this process, the walking wheel 101 can continuously roll on the surface of the side shell 5, synchronously driving a plurality of air flow plates 102 to rotate, the plurality of air flow plates 102 can generate air flow in the air cylinder 107, and finally the air flow can enter the gas guide shell 106, be accelerated by the two gas speed increasing volutes 109, and be sprayed from the air outlet nozzle 108, the high-speed air flow quickly blows to the deformation area of the module structure, effectively cooling the module structure, and the cooled module structure can be tested by secondary pressure.

[0047] The shape change recording assembly 12 comprises two mounting racks 121 fixedly installed on the top surfaces of the two air guide shells 106, and built-in springs 122 are fixedly installed in the two mounting racks 121, one end of each built-in spring 122 is fixedly installed with a roller holder 123, one end of the roller holder 123 is in sliding connection with the inner wall of the mounting rack 121, and a recording roller 124 is rotatably installed between the two roller holders 123, and a recording pen 125 is fixedly installed on one side outer wall of the roller holder 123, and one end of the recording pen 125 is in mutual contact with the outer surface of the track recording plate 8.

[0048] The specific implementation is that when the extrusion plate 64 is displaced, the shape change recording assembly 12 is synchronously displaced, because the side surface of the module structure is closely attached to and in contact with the recording roller 124 after installation and positioning, and as the module structure is deformed during detection, the recording roller 124 also changes in displacement according to the deformation law of the module structure, at this time, the recording pen 125 on one side changes in displacement, at this time, the recording pen 125 can record the displacement change track on the track recording plate 8 on one side, at the same time, the pointing mark 63 on one side of the extrusion plate 64 points to the scale on the scale mark 7 during the pressing process, and the pressing force is also detected and displayed on the digital display screen of the equipment, after the test is completed, various information about the test pressure, structure compression amount and structure deformation track can be collected, which can effectively assist subsequent test result analysis, and greatly improves the actual test effect of the whole equipment.

[0049] The top surface of the base 3 is fixedly installed with two sliding rails 11, and the structure positioning mechanism 4 is slidingly installed on the two sliding rails 11, the structure positioning mechanism 4 comprises a mounting seat 43, a screw hole 45 is arranged in the mounting seat 43, a positioning bolt 42 is in threaded connection in the screw hole 45, a positioning hole 9 matched with the positioning bolt 42 is arranged on the top surface of the base 3, and a positioning assembly 41 is arranged in the mounting seat 43, the positioning assembly 41 comprises a positioning motor 413, the positioning motor 413 is fixedly installed on one side outer wall of the mounting seat 43, a double-thread shaft 412 is fixedly installed at one end of an output shaft of the positioning motor 413, two sliding blocks 414 are in threaded connection with the double-thread shaft 412, and positioning triangular seats 411 are fixedly installed at the top ends of the two sliding blocks 414.

[0050] The specific embodiment is: when the module structure is positioned and installed, the module structure is directly installed in the inside of the structure positioning mechanism 4, the positioning motor 413 is started, the positioning motor 413 can drive the double-threaded shaft 412 to rotate, the double-threaded shaft 412 can drive the two sliders 414 on it to move close to each other, and the two positioning triangular seats 411 can be synchronously driven to move close to each other, and the two positioning triangular seats 411 can complete rapid positioning of the module structure. After positioning, the whole mounting seat 43 can be moved to the side until the positioning bolt 42 is located directly above the positioning hole 9, at which time the mounting seat 43 can be finally positioned by rotating the positioning bolt 42, and at this time the side wall of the module structure can be in contact with and pressed against the recording roller 124 of the deformation recording assembly 12.

[0051] Through the design, the module structure can be rapidly positioned before testing. Since the whole structure positioning mechanism 4 is designed to be movable, when the module structure is installed, the whole structure positioning mechanism 4 can be pulled out to the side for installation. At this time, the upper part of the whole structure positioning mechanism 4 is not blocked, and a larger installation area can be provided. After installation, the whole structure positioning mechanism 4 can be directly pushed into position, which greatly facilitates installation and improves installation efficiency, further improving the application effect of the equipment.

[0052] Working principle: when the module structure is tested, the module structure is first positioned and installed, the module structure is directly installed in the inside of the structure positioning mechanism 4, the positioning motor 413 is started, the positioning motor 413 can drive the double-threaded shaft 412 to rotate, the double-threaded shaft 412 can drive the two sliders 414 on it to move close to each other, and the two positioning triangular seats 411 can be synchronously driven to move close to each other, and the two positioning triangular seats 411 can complete rapid positioning of the module structure. After positioning, the whole mounting seat 43 can be moved to the side until the positioning bolt 42 is located directly above the positioning hole 9, at which time the mounting seat 43 can be finally positioned by rotating the positioning bolt 42, and at this time the side wall of the module structure can be in contact with and pressed against the recording roller 124 of the deformation recording assembly 12.

[0053] After installation and positioning, testing is performed. The hydraulic module 61 is turned on, and the hydraulic module 61 drives the extrusion plate 64 to move downward. The extrusion plate 64 contacts the upper surface of the module structure and continuously exerts pressure downward. As the pressure increases, the module structure deforms, and the extrusion plate 64 can drive the walking assembly 10 to move downward synchronously. After the first stage of testing is completed, the extrusion plate 64 is driven again to drive the walking assembly 10 to reset, and secondary extrusion is performed again. During this process, the walking wheels 101 can continuously roll on the surface of the side shell 5, synchronously driving the plurality of airflow plates 102 to rotate. The plurality of airflow plates 102 can generate airflow in the air cylinder 107. Finally, the airflow can enter the air guide shell 106, accelerate through the two gas speed-up volutes 109, and be sprayed from the air outlet 108. The high-speed airflow quickly blows to the deformation area of the module structure, effectively cooling the module structure. At this time, the cooled module structure can be tested for secondary pressure.

[0054] When the extrusion plate 64 moves, the deformation recording assembly 12 can be driven to move synchronously. Since the module structure is installed and positioned, its side surface is tightly attached to and contacts the recording roller 124. As the module structure deforms during testing, the recording roller 124 also deforms according to the deformation law of the module structure. At this time, the recording pen 125 on one side can also move, and the recording pen 125 can record the trajectory of the displacement change on the trajectory recording plate 8 on one side. At the same time, the pointing mark 63 on one side of the extrusion plate 64 can also point to the scale on the scale mark 7, and the extrusion force can be detected and displayed on the digital screen on the device. After testing is completed, various information about the test pressure, structure compression amount, and structure deformation trajectory can be collected, which can effectively assist subsequent analysis of test results. The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and inventive concepts of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
