[0028] As Figures 1 to 4 shown, an embodiment of the present utility model provides an aluminum alloy main beam lifting mechanism, which includes a main beam connection seat 1. The side of the main beam connection seat 1 can be installed with a first aluminum alloy main beam 2, and then the main beam connection seat 1 can be fixed to the side of the first aluminum alloy main beam 2 through bolts. At the same time, the number of the main beam connection seats 1 is two, and the two main beam connection seats 1 can be respectively installed on the sides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, and the main beam connection seats 1 are respectively installed on the opposite sides away from the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. When splicing the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, rectangular grooves 401 can be opened at the top and bottom of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, so that a fixing plate 402 can be installed inside the rectangular grooves 401. At the same time, first threaded grooves 403 and second threaded grooves 404 can be opened at the top and side of the installed fixing plate 402, so that the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3 can be spliced using a first threaded rod 405 and a second threaded rod 406. When installing the second fixing member 5, a fixing block 501 is installed on the side of the first aluminum alloy main beam 2. At the same time, an installation groove 502 is opened on the side of the fixing block 501 close to the first aluminum alloy main beam 2, so that a plug board 503 can be inserted into the installation groove 502. The plug board 503 can be inserted into the fixing block 501, and then a third threaded rod 505 can be threadedly connected through the opened third threaded groove 504, so that the third threaded rod 505 can fix the fixing block 501. At the same time, for the opened fourth threaded groove 506, the fourth threaded rod 507 that is threadedly connected can fix the plug board 503. Thus, when the plug board 503 is inserted into the fixing block 501, the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3 can be spliced.

[0029] Specifically, the number of the first fixing members 4 is two, and the two first fixing members 4 are respectively installed on the top and bottom of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. The number of the second fixing members 5 is two, and the two second fixing members 5 are installed on the left and right sides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. Since the number of both the first fixing members 4 and the second fixing members 5 is two, the first fixing members 4 can fix the top and bottom of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, and at the same time, the second fixing members 5 can fix the left and right sides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, thus facilitating the splicing of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3.

[0030] Specifically, a suspension plate 6 is installed on the top of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. A driving motor 7 is fixedly connected to the side of the suspension plate 6. The output shaft of the driving motor 7 is fixedly connected to a rotating rod 8, and the rotating rod 8 is rotatably connected inside the suspension plate 6. A clamping structure 9 is rotatably connected to the outer wall of the rotating rod 8. A suspension ring 10 is fixedly installed on the top of the suspension plate 6. When the installed suspension plate 6 is in place, the output shaft of the driving motor 7 installed on the side of the suspension plate 6 can drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, it can drive the clamping structure 9 to move, so that the clamping structure 9 can fix the outside of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3.

[0031] Specifically, the clamping structure 9 includes a slider 901. The slider 901 is slidably connected inside the suspension plate 6. The bottom of the slider 901 is fixedly connected to a mounting plate 902. The right mounting block 903 is fixedly connected to the right side inside the mounting plate 902. A regulating rod 904 is rotatably connected to the left side of the mounting plate 902. The limiting plate 905 is fixedly connected to the left side inside the mounting plate 902. The left mounting block 906 is fixedly connected to the side of the regulating rod 904 close to the inside of the mounting plate 902, and the left mounting block 906 is slidably connected inside the limiting plate 905. When the installed slider 901 is in place, the mounting plate 902 installed at the bottom of the slider 901 can be installed on the outside of the main beam. At the same time, when the regulating rod 904 rotates, it can drive the left mounting block 906 to slide inside the limiting plate 905, and at the same time, the limiting plate 905 can limit the left mounting block 906. When the left mounting block 906 moves, the left and right sides of the main beam can be fixed by the left mounting block 906 and the right mounting block 903.

[0032] Specifically, the number of the sliders 901 is two. The internal threads of the two sliders 901 are opposite. The mounting plates 902 installed at the bottoms of the two sliders 901 are respectively installed on the outsides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. Since the internal threads of the two sliders 901 are opposite, the two sliders 901 can slide on the outsides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, thus facilitating the lifting of the main beam.

[0033] Specifically, rubber pads are installed on the opposite surfaces of the right mounting block 903 and the limiting plate 905, and the right mounting block 903 and the limiting plate 905 are of the same size. Due to the installed rubber pads, it is convenient to protect the exteriors of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3.

[0034] Working principle: During operation, when splicing the aluminum alloy main beams, the main beam connecting seat 1 can be installed at one end far from the opposite surfaces of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, so that the main beam connecting seat 1 can be fixedly connected to the exteriors of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3 through bolts. When the first fixing member 4 is in use, a rectangular groove 401 can be opened at the top of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, so that a fixing plate 402 can be installed inside the rectangular groove 401. The top and side of the fixing plate 402 are respectively provided with a first threaded groove 403 and a second threaded groove 404, so as to facilitate the splicing of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3 by the first threaded rod 405 and the second threaded rod 406. Since the first fixing member 4 is installed at the top and bottom of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, it is convenient to fix the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. At the same time, the second fixing members 5 installed on the left and right sides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3 enable a fixing block 501 to be installed on the side of the first aluminum alloy main beam 2. A plug board 503 can be slidably connected inside the fixing block 501. The third threaded groove 504 opened penetrates through the plug board 503 and the side of the first aluminum alloy main beam 2, so that the rotating third threaded rod 505 can fix the fixing block 501. At the same time, the fourth threaded groove 506 opened can use the fourth threaded rod 507 to fix the plug board 503, thus facilitating the splicing of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3; when lifting the aluminum alloy main beam, a lifting plate 6 can be installed at the top of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, so that the lifting rings 10 installed on the top of the lifting plate 6 can facilitate the lifting of the device; when fixing the device, the output shaft of the driving motor 7 can be used to drive the rotating rod 8 to rotate, and the rotating rotating rod 8 can drive two sliders 901 to move inside the lifting plate 6. Since the internal threads of the two sliders 901 are opposite, it is convenient for the two sliders 901 to move. At the same time, the mounting plate 902 installed at the bottom of the slider 901 can be installed on the exteriors of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3. When rotating the adjusting rod 904, the left mounting block 906 can be driven to slide inside the limiting plate 905, and at the same time, the limiting plate 905 can limit the left mounting block 906, so as to facilitate the left mounting block 906 and the right mounting block 903 to fix the left and right sides of the first aluminum alloy main beam 2 and the second aluminum alloy main beam 3, and thus the lifting rings 10 installed on the top of the lifting plate 6 facilitate the lifting of the device.
