[0002] Metal prefabricated modular houses are temporary and semi-permanent buildings with steel as the main frame and modular design. They can be quickly assembled using bolted connections. The container can be prefabricated and includes walls, roof, and floor structure. The interior can be equipped with water, electricity, and insulation devices. They are characterized by convenient installation, mobility, and reusability, and are used for construction site dormitories, temporary offices, and emergency shelters.

[0003] Knurling machines are used to knurl patterns on the surface of metal components of prefabricated modular housing. These patterns enhance the friction between components, improve connection stability, prevent loosening after assembly, increase the fit between the frame and the ground and other components, improve the overall load-bearing capacity and structural safety of the modular housing, and ensure that the modular housing is stable and reliable during transportation, installation and use.

[0004] The long profiles of metal prefabricated container frames have smooth surfaces and low friction, which can cause slippage during installation and use, affecting assembly stability and safety.

The left and right sides of each side plate 41 are fixedly connected to mounting plates 44. The outer sides of each mounting plate 44 are provided with mounting components 45. The mounting components 45 include multiple bolts 451. The inner sides of the multiple bolts 451 are threaded to the outer sides of the multiple mounting plates 44. The outer sides of each mounting plate 44 are provided with two threaded holes 452. The bottom inner side of the bracket 2 is provided with a clamping component 46. The clamping component 46 includes multiple telescopic rods 461. The outer sides of each telescopic rod 461 are fixedly connected to the bottom inner side of the bracket 2. The adjacent telescopic rods 461 are fixedly connected with positioning clamps 462. Specifically, when the protective mechanism 4 is working, the side plates 41 on the front and rear sides of the top of the support frame 1 and the top plate 42 on the top form a protective space to block the flying of debris generated during the knurling process. The reinforcing ribs 43 on the outer side of the side plate 41 enhance the structural strength of the side plate 41. Through the cooperation of the side plate 41 and the reinforcing ribs 43, the stability of the protective structure is improved.

[0027] Reference Figure 2 , Figure 3 and Figure 5The moving mechanism 5 includes two guide rails 51, the outer sides of which are fixedly connected to the inner side of the bracket 2. The front and rear sides of the moving vehicle 31 are fixedly connected to sliders 52. The left and right sides of the moving vehicle 31 are provided with driving components 53. The driving components 53 include two slide rods 531, the left and right ends of which are fixedly connected to the inner side of the bracket 2. The left and right sides of the moving vehicle 31 are fixedly connected to hydraulic cylinders 532. The inner side of the support frame 1 is provided with a support component 54. The support component 54 includes a support plate 541, the left and right sides of which are fixedly connected to the left and right ends of the inner side of the support frame 1, respectively. The front and rear ends of the inner side of the support frame 1 are rotatably connected to multiple support wheels 542. Specifically, when the moving mechanism 5 is working, the guide rail 51 on the inner side of the bracket 2 cooperates with the slider 52 on the front and rear sides of the moving vehicle 31. The slider 52 slides along the guide rail 51 to guide the moving vehicle 31 to move smoothly. Through the cooperation of the guide rail 51 and the slider 52, the directional movement of the moving vehicle 31 is realized. In the drive assembly 53 on the left and right sides of the mobile vehicle 31, the slide rod 531 is fixed inside the bracket 2, and the hydraulic cylinder 532 extends and retracts to push the mobile vehicle 31 to move along the slide rod 531. Through the cooperation of the slide rod 531 and the hydraulic cylinder 532, the mobile vehicle 31 is provided with the power to move and the direction of movement is restricted. In the support assembly 54 inside the support frame 1, the support plate 541 is fixed inside the support frame 1, and the support wheel 542 rotates along the front and rear ends of the inner side of the support frame 1. The container house base is placed on the support wheel 542. Through the cooperation of the support plate 541 and the support wheel 542, the support and transportation of the container house base are realized. When movement is required, the hydraulic cylinder 532 extends and retracts, pushing the moving vehicle 31 to move along the slide bar 531. The slider 52 slides synchronously along the guide rail 51, driving the moving vehicle 31 to move along a predetermined trajectory. The container base is placed on the support wheel 542 and is transported as the support wheel 542 rotates. The support plate 541 provides stable support for the support wheel 542.

[0028] Working principle: Operate the protective mechanism 4, locate the mounting plates 44 on the left and right sides of the side plate 41, align the bolts 451 of the mounting component 45 with the threaded holes 452 on the outer side of the mounting plate 44, rotate the bolts 451 to make them threaded and fixed, thereby fixing the two side plates 41 to the top front and rear sides of the support frame 1 respectively. At this time, the top plate 42 of the side plate 41 and the two side plates 41 enclose a protective space. The multiple reinforcing ribs 43 on the outer side of the side plate 41 are fixedly connected to the side plate 41, which can enhance the structural strength of the side plate 41 and prevent the side plate 41 from deforming during processing. Operate the clamping component 46 at the bottom of the inner side of the bracket 2 to control the extension and retraction of multiple telescopic rods 461. The extension and retraction of the telescopic rods 461 will drive the adjacent positioning clamps 462 to move, placing the container base frame between the positioning clamps 462, so that the positioning clamps 462 hold the container base frame and prevent the container base frame from shifting during subsequent processing. Next, operate the moving mechanism 5 and start the hydraulic cylinders 532 in the drive components 53 on the left and right sides of the moving vehicle 31. When the hydraulic cylinders 532 extend and retract, they will generate thrust, pushing the moving vehicle 31 to move along the slide bar 531 on the inner side of the bracket 2. At the same time, the sliders 52 on the front and rear sides of the moving vehicle 31 will slide along the two guide rails 51 on the inner side of the bracket 2. The cooperation between the guide rails 51 and the sliders 52 can ensure that the moving trajectory of the moving vehicle 31 is stable and will not deviate. Place the container base frame on the multiple support wheels 542 of the support component 54 on the inner side of the support frame 1. The support wheels 542 will rotate along the front and rear ends of the inner side of the support frame 1, thereby driving the container base frame to be transported. The support plate 541 on the inner side of the support frame 1 is fixed to the left and right ends of the inner side of the support frame 1 respectively, which can provide stable support for the support wheels 542 and ensure the smoothness of the transport process. Operate the knurling mechanism 3, rotate the knob 3102 of the bottom adjustment component 310 of the support frame 1. Rotating the knob 3102 will drive the screw 3101, which is threaded to the bottom of the support frame 1, to rotate, thereby adjusting the height of both sides of the limit strip 37 to a suitable processing position. During the movement of the moving carriage 31, it will drive the bottom fixed seat 32 to move synchronously, so that the knurling wheel 35, which is connected to the outer wall of the rotating shaft 34 via the bearing 33 on the inner side of the fixed seat 32, is aligned with the processing position of the box frame. Control the extension of multiple hydraulic rods 381 of the bottom pressing component 38 of the moving carriage 31. The extension of 381 will push the fixed seat 32 downward through the fixed ring 382 at the bottom, causing the knurling wheel 35 to press against the bottom frame of the container house. The rotating shaft 34 will rotate, driving the knurling wheel 35 to rotate through the bearing 33, performing knurling on the bottom frame of the container house. The limiting shafts 36 at the front and rear ends of the rotating shaft 34 will cooperate with the limiting strips 37 on the front and rear sides of the top of the support frame 1 to limit the downward pressing depth of the knurling wheel 35. The multiple telescopic rods 391 of the top stabilizing component 39 of the fixed seat 32 will move up and down with the fixed seat 32. The multiple springs 392 on the outer wall can buffer the vibration generated during processing and enhance the stability of the fixed seat 32.
