[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] like Figures 1 to 3 As shown below, the structure and function of a prefabricated steel structure will be described in detail.

[0033] A prefabricated steel structure includes a support pipe 11 with two fastening discs 12. Each fastening disc 12 has multiple V-shaped grooves 14. The two fastening discs 12 fasten together with the overlapping pipe 13 through the V-shaped grooves 14. One fastening disc 12 is fixedly connected to the support pipe 11, and the other fastening disc 12 is slidably connected to the support pipe 11. The two fastening discs 12 are connected by a screw 21.

[0034] When using, such as Figure 1As shown, one of the fastening discs 12 is pre-fixed to the support tube 11 by welding. The overlapping pipe 13 to be installed is placed in the V-shaped groove 14 on the fastening disc 12. The other fastening disc 12 is pushed to slide on the support tube 11. The two fastening discs 12 fasten the overlapping pipe 13 through the V-shaped groove 14. Furthermore, the connection of the two fastening discs 12 is completed by the screw 21. At the same time, the two fastening discs 12 are tightened by the nut connected by the thread on the screw 21. The relative distance between the two fastening discs 12 is adjusted by the nut, so that the two fastening discs 12 can fasten the overlapping pipe 13 of different diameters, thereby completing the connection between the overlapping pipe 13 and the support tube 11.

[0035] Furthermore, multiple V-shaped grooves 14 are provided, and the V-shaped grooves 14 can be set at different angles, so that multiple connecting pipes 13 can be connected to the support pipe 11 at different angles according to different usage requirements.

[0036] Furthermore, in order to ensure the stability of the connection between the support tube 11 and the connecting tube 13, multiple V-shaped protrusions 15 are provided in each V-shaped groove 14. When the two fastening discs 12 approach each other, the connecting tube 13 is snapped into the two V-shaped grooves 14, and multiple V-shaped protrusions 15 contact the connecting tube 13. The multiple V-shaped protrusions 15 squeeze and limit the connecting tube 13 to ensure the stability of the connection between the support tube 11 and the connecting tube 13.

[0037] like Figures 4 to 10 As shown, in order to facilitate the processing of the V-shaped groove 14, a cutting device is designed. The structure and function of the cutting device are described in detail below.

[0038] The cutting device includes a device support 31, a clamping plate 32 rotatably connected to the device support 31, a plurality of clamping blocks 33 slidably connected to the clamping plate 32, a threaded plate 34 rotatably connected to the clamping plate 32, and the plurality of clamping blocks 33 are all threadedly connected to the threaded plate 34.

[0039] A conical friction wheel I 41 is rotatably connected to the device support 31, and a conical friction wheel II 42 is rotatably connected to the device support 31. The conical friction wheel I 41 and the conical friction wheel II 42 are connected by belt drive. A power mechanism I that drives the conical friction wheel I 41 to rotate is fixedly connected to the device support 31. The power mechanism I is preferably a servo motor. The conical friction wheel II 42 is connected to the clamping plate 32 by transmission.

[0040] A telescopic mechanism I 43 is fixedly connected to the device bracket 31. A tension bracket 44 is fixedly connected to the telescopic end of the telescopic mechanism I 43. The transmission belt between the conical friction wheel II 42 and the clamping plate 32 passes through the tension bracket 44.

[0041] A telescopic mechanism II 51 is fixedly connected to the device bracket 31. A movable bracket 52 is fixedly connected to the telescopic end of the telescopic mechanism II 51. A lead screw 53 is rotatably connected to the movable bracket 52. A power mechanism II for driving the lead screw 53 to rotate is fixedly connected to the movable bracket 52. The power mechanism II is preferably a servo motor. A sliding bracket 54 is slidably connected to the movable bracket 52. The sliding bracket 54 is threadedly connected to the lead screw 53. A telescopic mechanism III 55 is fixedly connected to the sliding bracket 54. A cutting bracket 56 is fixedly connected to the telescopic end of the telescopic mechanism III 55.

[0042] Two rotating disks 61 are rotatably connected to the cutting bracket 56. A power mechanism Ⅲ for driving the rotating disks 61 to rotate is fixedly connected to the cutting bracket 56. The power mechanism Ⅲ is preferably a servo motor. A telescopic mechanism Ⅳ 62 is fixedly connected to each rotating disk 61. A cutting disk 63 is fixedly connected to the telescopic end of each telescopic mechanism Ⅳ 62. Multiple cutting blades 64 are hinged to each cutting disk 63.

[0043] Each rotating disk 61 is fixedly connected to a telescopic mechanism V65, each telescopic mechanism V65 is fixedly connected to a push bracket 66, each push bracket 66 is rotatably connected to a push disk 67, the push disk 67 is slidably connected to the telescopic end of the telescopic mechanism IV62, and multiple connecting rods 68 are hinged between the push disk 67 and the cutting tool 64.

[0044] A sensor 57 is fixedly connected to the movable bracket 52. The sensor 57 is connected to the power mechanism I. The sliding bracket 54 can contact the sensor 57.

[0045] In use, the fastening disc 12 to be processed is placed between multiple clamping blocks 33. The threaded disc 34 is rotated. When the threaded disc 34 rotates, the clamping blocks 33 are moved through the threads, so that the multiple clamping blocks 33 move closer to each other to clamp the fastening disc 12.

[0046] When the power mechanism III is started, the output shaft of the power mechanism III begins to rotate. The output shaft of the power mechanism III drives the rotating disk 61 to rotate, the rotating disk 61 drives the telescopic mechanism IV 62 to rotate, the telescopic mechanism IV 62 drives the cutting disk 63 to rotate, and the cutting disk 63 drives multiple cutting tools 64 to rotate.

[0047] When the power mechanism II is started, the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the lead screw 53 to rotate. When the lead screw 53 rotates, it drives the sliding bracket 54 to move through the thread, so that the sliding bracket 54 slides on the moving bracket 52. The sliding bracket 54 drives the telescopic mechanism III 55 to move. The telescopic mechanism III 55 drives the cutting bracket 56 to move. The cutting bracket 56 drives the rotating disk 61 to move. The rotating disk 61 drives multiple cutting tools 64 to move, so that the multiple cutting tools 64 move closer to the fastening disk 12 and cut the fastening disk 12, so that a V-shaped groove 14 is formed on the fastening disk 12.

[0048] Furthermore, the telescopic mechanism II 51 can be activated. The telescopic mechanism II 51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 51 drives the movable support 52 to move, thereby adjusting the position of the movable support 52. The movable support 52 drives the cutting tool 64 to move, thereby adjusting the initial position of the multiple cutting tools 64.

[0049] Furthermore, the output shaft of the power mechanism II reciprocates, that is, the output shaft of the power mechanism II first rotates to push the cutting tool 64 to feed and cut the fastening disc 12, and then the output shaft of the power mechanism II rotates in the opposite direction, and the output shaft of the power mechanism II drives the cutting tool 64 to return to the starting position and reset.

[0050] Then the sliding bracket 54 is reset, and the sliding bracket 54 contacts the sensor 57. The sensor 57 can be a contact sensor. The sensor 57 is connected to the power mechanism I through the electronic control means commonly used in the art. That is, when the sensor 57 is squeezed, the sensor 57 controls the output shaft of the power mechanism I to rotate one revolution. That is, each time the sensor 57 is squeezed, the output shaft of the power mechanism I rotates only one revolution. The output shaft of the power mechanism I drives the conical friction wheel I 41 to rotate one revolution. The conical friction wheel I 41 drives the conical friction wheel II 42 to rotate. The conical friction wheel II 42 drives the clamping plate 32 to rotate. The clamping plate 32 drives the fastening plate 12 to rotate, thereby changing the processing position. Then the sliding bracket 54 reciprocates multiple times. At the same time, the clamping plate 32 also continuously drives the fastening plate 12 to rotate, thereby completing the processing of multiple V-shaped grooves 14 on the fastening plate 12.

[0051] Furthermore, the telescopic mechanism I43 is activated. The telescopic mechanism I43 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I43 drives the pull bracket 44 to move. The pull bracket 44 pulls the transmission belt between the conical friction wheel I41 and the conical friction wheel II42 to move, thereby adjusting the transmission ratio between the conical friction wheel I41 and the conical friction wheel II42. This adjusts the angle of rotation of the fastening disc 12 each time the conical friction wheel I41 rotates, resulting in different interval angles after the multiple V-shaped grooves 14 are processed. Consequently, when the overlapping pipe 13 is installed, the interval angle between the overlapping pipes 13 is also different, thus meeting different installation requirements.

[0052] Furthermore, the multiple cutting tools 64 on both sides are staggered to form different V-shaped grooves 14. In order to process the V-shaped grooves 14 with different inclination angles on both sides, the telescopic mechanism IV 62 can be activated. The telescopic mechanism IV 62 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism IV 62 drives the cutting disc 63 to move. The cutting disc 63 drives the cutting tool 64 to move. At the same time, the telescopic mechanism V 65 is activated. The telescopic mechanism V 65 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism V 65 drives the push bracket 66 to move. The push bracket 66 drives the push disc 67 to move. The push disc 67 drives the connecting rod 68 to move. The connecting rod 68 drives the cutting tool 64 to move, thereby adjusting the inclination angle and spacing of the cutting tools 64 on both sides, and thus processing different types of V-shaped grooves 14.
