Both sides of the installation box 22 are inserted with latch rods 23. One end of the two latch rods 23 set inside the installation box 22 is fixedly connected to a transmission plate 24. Two fixed plates 25 are set between the two transmission plates 24. Both sides of the fixed plate 25 are fixedly connected to the adjacent transmission plates 24 with a plurality of springs 26. An elliptical block 27 is set between the two transmission plates 24. The elliptical block A bolt three 28 is fixedly installed inside 27, and the bottom end of the bolt three 28 extends to the outside of the installation box 22. A fixing plate two 29 is threadedly sleeved on the outer side of the bolt three 28. The fixing plate two 29 is fixedly connected to the installation box 22. A welding device support structure 3 is arranged between the two support plates one 13. The welding device support structure 3 includes a support plate three 31, a lighting assembly slidably installed on the support plate three 31, a battery support frame 34, a plurality of placement tubes 38 fixedly installed on the outer side of the battery support frame 34, and a plurality of storage batteries 36 inserted on the battery support frame 34.

[0022] Specifically, the specific method of using the assembled welding device composed of the assembled transport structure 1, the assembled clamping structure 2 and the welding device support structure 3 is as follows: A plurality of universal wheels 12 are installed at the bottom of the base plate 11, so that the assembled transport structure 1 can move, which is convenient for moving the assembled welding device and meets the needs of assembling and welding small building materials at different processing positions during the construction process.

[0023] When the assembled welding device moves to a suitable position, support plates 13 are rotatably installed on the left and right sides of the top of the bottom plate 11, and support plates 17 are arranged on the front and rear sides of the top of the bottom plate 11. The outer hoop 116 is sleeved on the outside of the box body composed of two support plates 13 and two support plates 17, and a support plate 31 is arranged between the two support plates 13. The inside of the box body is supported by the support plate 31, and the box body, the support plate 31 and the bottom plate 11 cooperate to form a transport box; thread grooves 119 are provided on the outside of the support plates 13 and 17, and bolts 120 are inserted into the four thread grooves 118 provided on the outside of the outer hoop 116, and one end of the bolt 120 is arranged inside the thread groove 119, and the up and down movement of the outer hoop 116 is limited by the bolts 120; By rotating the four bolts 120 to make the four bolts 120 leave the inside of the thread groove 2 119, the outer hoop 116 can be pulled down. Guide grooves 2 115 are provided on the outside of the support plate 13 and the support plate 2 17, and the guide blocks 117 provided in the four guide grooves 2 115 are fixedly installed in the outer hoop 116. Since the two support plates 13 and the two support plates 17 are supported by the support plate 3 31, the outer hoop 116 can only move up and down at this time. When the outer hoop 116 moves downward to make the four guide blocks 117 enter the four guide grooves 114 provided on the outside of the bottom plate 11, the two support plates 1 13 and the two support plates 17 can move in the direction away from the support plate 3 31, so that the support plates 1 13 and the two support plates 17 can be quickly opened, so that the transport box can be opened, and the equipment inside the transport box can be taken out for use.

[0024] When the outer hoop 116 moves down and is sleeved on the outside of the bottom plate 11, the support plate 13 and the support plate 2 17 lose their limit. Since the two sides of the bottom of the support plate 13 are provided with square grooves 14, the mounting frame 15 arranged inside the square grooves 14 is fixedly connected to the bottom plate 11, and the mounting frame 15 and the support plate 13 are rotatably connected with the rotating shaft 16. The support plate 13 can rotate, but the support plate 13 will not be completely disconnected from the bottom plate 11. After the support plate 13 is controlled to rotate 90°, the bottom of the support plate 13 is supported by the outer hoop 116, so that the support plate 13 remains parallel to the horizontal plane. Since two internal threaded tubes 121 are fixedly installed on the top of one side of the support plate 13 and the support plate 2 17, the bolt 2 123 inserted in the internal threaded tube 121 is fixedly connected to the support block 122 at one end away from the battery support frame 34. At this time, the other end of the bolt 2 123 extends to the top of the bottom plate 11, and the bolt 2 123 is rotated, and the bolt 2 123 rotates and moves downward, and the support block 122 rotates and moves downward to contact the ground, so that the support block 122 can move down a certain distance, and the support plate 13 parallel to the horizontal plane is supported by the support block 122, which ensures the stability of the support plate 13 as a processing platform, provides a clean and flat operating platform for the staff to use the assembled welding device, and ensures the quality of the welding processing of building materials; Square grooves 2 18 are provided on both sides of the bottom of the support plate 2 17, and two mounting frames 3 112 fixedly connected to the support plate 2 17 are provided inside the square grooves 2 18. A mounting frame 4 111 rotatably connected to the mounting frame 2 19 in the support assembly provided between the two mounting frames 3 112, and one end of the two mounting frames 3 112 extends to the inside of the mounting frame 4 111. The rotating support plate 2 17 drives the fixedly connected mounting frame 3 112 to rotate. When the support plate 2 17 rotates and is supported by the outer hoop 116 to be parallel to the horizontal plane, the two mounting frames 3 112 are aligned with the two square grooves 3 110 provided at the two ends of the outer side of the mounting frame 2 19, and then the support plate 2 17 is pulled to make the mounting frame 3 112 pass through the square grooves 3 110 and leave the inside of the mounting frame 4 111, so that the support plate 2 17 can be separated from the bottom plate 11, and the support plate 2 17 can be disassembled for use.

[0025] Since two assembly clamping structures 2 are arranged on the top of the support plate 13, the U-shaped frame 21 in the assembly clamping structure 2 is fixedly connected to the top of the support plate 13. After the support plate 13 is flipped 90°, the U-shaped frame 21 is flipped synchronously. At this time, the inner concave part of the U-shaped frame 21 set in the U shape faces upward, and the square groove 218 opened on the support plate 21 is sleeved on the outer side of the U-shaped frame 21. When the mounting frame 3 112 arranged inside the square groove 218 is inserted into the U-shaped frame 21 and supported and limited, the alignment of the support plate 21 and the support plate 13 is completed. Then, the bolt 2 123 installed on the support plate 21 is rotated, and the bolt 2 123 is rotated to make the support block 122 move down and contact the ground, and the support plate 2 17 is supported on the ground; and an installation box 22 is fixedly connected inside the U-shaped frame 21, and the two latch rods 23 inserted on both sides of the installation box 22 are aligned with the circular grooves 113 opened on the outer sides of the two mounting frames 3 112; In addition, two latch rods 23 are arranged at one end inside the installation box 22 and are fixedly connected to a transmission plate 24. Two fixed plates 25 arranged between the two transmission plates 24 are fixedly connected to the installation box 22 and cannot move. Both sides of the fixed plate 25 are fixedly connected to the adjacent transmission plates 24 with multiple springs 26, and the transmission plates 24 supported and limited by the springs 26 can move; an elliptical block 27 is arranged between the two transmission plates 24, and the bottom end of the bolt 3 28 fixedly installed inside the elliptical block 27 extends to the outside of the installation box 22, and the fixed plate 29 with a threaded sleeve on the outside of the bolt 3 28 is fixedly connected to the installation box 22; Therefore, bolt three 28 is rotated to make bolt three 28 rotate and move downward, and the elliptical block 27 set to be elliptical rotates and moves downward. During the rotation and downward movement of the elliptical block 27, the two transmission plates 24 are pushed, so that the two transmission plates 24 are synchronously displaced in the direction away from the fixed plate 1 25; when the elliptical block 27 moves downward and contacts the inner wall of the installation box 22 and is restricted, the elliptical block 27 rotates 90°. At this time, the latch rod 23 fixedly connected to the transmission plate 24 moves and inserts into the adjacent circular groove 113. The latch rod 23 restricts the mounting frame three 112 inside the U-shaped frame 21, completing the installation of the support plate two 17 and the support plate one 13, so that the support plate two 17 and the support plate one 13 form a larger operating platform.

[0026] In summary, during the use of the prefabricated welding device provided in the present application, after the prefabricated transport structure 1 is operated and opened, the support plate 1 13 and the support plate 2 17 can be combined into an operating platform, providing a flat and clean operating platform for the staff, meeting the needs of efficient welding processing in the complex environment of the construction site, and providing a prefabricated welding device with a movable, detachable and assembled operating platform, thereby reducing construction cost investment.

[0027] A plurality of placement tubes 38 are fixedly installed on the outside of the battery support frame 34, and a clamping frame 314 is fixedly connected to the outside of each of the placement tubes 38. A control valve 310 is fixedly installed on the gas outlet end of a gas storage tank 39 arranged inside one of the placement tubes 38. An internal threaded joint 311 threadedly installed on the gas outlet end of the control valve 310 is rotatably connected to an air guide pipe 312. After the internal threaded joint 311 is rotated to remove the internal threaded joint 311 from the gas outlet end of the control valve 310, the gas storage tank 39 can be removed from the inside of the placement tube 38 for replacement. The welding gun 313 fixedly connected at one end of the air guide tube 312 is partially inserted into the clamping frame 314. The welding gun 313 is pulled out from the clamping frame 314, and then the control valve 310 is opened. The building materials can be welded by the welding gun 313, and the two support plates 13 and the two support plates 2 17 form two operating platforms to meet the welding construction needs of multiple workers.

[0028] Since the battery support frame 34 is fixedly connected to the top of the base plate 11, a plurality of threaded grooves 35 are provided on the top of the battery support frame 34, and the bottom ends of the plurality of bolts 4 32 threadedly connected on the support plate 31 are inserted into the adjacent threaded grooves 35. By rotating the bolts 4 32 so that the bolts 4 32 leave the threaded grooves 35, the fixation between the support plate 31 and the battery support frame 34 can be removed, and the support plate 31 can be disassembled, so that the gas tank 39 placed inside the tube 38 can be replaced conveniently.

[0029] A plug 33 is fixedly connected to the bottom of the support plate three 31. After the support plate three 31 is installed on the top of the battery support frame 34, the plug 33 is inserted into the socket 37 fixedly inserted on the battery support frame 34 to supply power to the lighting component electrically connected to the plug 33.

[0030] A lighting lamp 316 is installed on the lamp holder 315 in the lighting assembly. A limiting plate 317 is fixedly installed at the bottom of both sides of the lamp holder 315. The limiting plate 317 is arranged at the bottom of the supporting plate 31. A limiting plate 318 is fixedly connected to the top of both sides of the lamp holder 315. The limiting plate 318 is arranged at the top of the supporting plate 31. The setting of the limiting plate 317 and the limiting plate 318 prevents the lamp holder 315 from being completely disconnected from the supporting plate 31. A groove 320 is arranged at the bottom of the limiting plate 318. The groove 320 is opened on the supporting plate 31. When the lamp holder 315 is pushed down, the limiting plate 318 enters the groove 320 to restore the top of the supporting plate 31 to a relatively flat state. A cloth belt 319 is fixedly connected between the two limiting plates 318, and the cloth belt 319 is set on the top of the support plate 31. The lamp holder 315 is pulled up by the cloth belt 319 to move up the lamp holder 315, and the lighting lamp 316 is exposed for lighting. The lamp holder 315 and the support plate 31 are in an interference fit state, and the lamp holder 315 remains in place before receiving a certain force.

[0031] In addition, the mounting frame four 111 and the mounting frame two 19 are in an interference fit state. The mounting frame four 111 will rotate inside the mounting frame two 19 only after being subjected to a certain force, so that the relative position between the mounting frame four 111 and the square groove three 110 remains in a relatively stable state, respectively supporting the installation of the support plate two 17 and the base plate 11.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
