The top of the fixed sleeve 21, and the extension rod 22 is fixedly connected to the base 10, two support assemblies 28 are respectively arranged on both sides of the fixed sleeve 21, and the two support assemblies 28 are used to support the base 10, a movable groove is opened on the top of the fixed sleeve 21, the first trapezoidal screw 24 is rotatably connected to the inside of the movable groove, the extension rod 22 is sleeved and threadedly connected to the top of the first trapezoidal screw 24, two limit blocks 23 are respectively arranged on both sides of the extension rod 22, and the extension rod 22 and the limit blocks 23 are both slidably connected to the inside of the movable groove, The first bevel gear 25 is fixedly arranged inside the first trapezoidal lead screw 24, the second bevel gear 26 is meshedly connected to one side of the first bevel gear 25, the first knob 27 is rotatably connected to the outside of the fixed sleeve 21, one end of the first knob 27 is fixedly connected to the second bevel gear 26, and the first knob 27 drives the second bevel gear 26 to rotate, so that the first bevel gear 25 meshed with it drives the first trapezoidal lead screw 24 to rotate, thereby driving the extension rod 22 threadedly connected thereto to slide in the movable groove, thereby changing the base 1 0, so that when multiple supporting devices support the steel truss, the supporting devices can be adjusted to be in the same plane, reducing the interference of uneven ground on the assembly of the steel structure and improving the accuracy of the assembly of the steel structure. The limit blocks 23 on both sides of the extension rod 22 limit the sliding of the extension rod 22 to prevent the extension rod 22 from rotating with the first trapezoidal lead screw 24. The first trapezoidal lead screw 24 has a self-locking function to fix the height of the base 10, so that the steel structure on the base 10 will not drive the base 10 and the extension rod 22 to move downward during assembly.

[0022] Please refer to Figure 1 and Figure 2The two support components 28 include a telescopic column 281, an adjusting bolt 282, a connecting seat 283, and a fixing nail 284. The telescopic column 281 is fixedly arranged on one side of the fixing sleeve 21, and the top of the telescopic column 281 is fixedly connected to the base 10. The bottom of the telescopic column 281 is a fixed end, and the top is a movable end. The movable end is connected with the fixed end through insertion. The two adjusting bolts 282 are respectively arranged on both sides of the telescopic column 281. One end of the two adjusting bolts 282 extends into the interior of the fixed end of the telescopic column 281 and is tightly attached to the movable end of the telescopic column 281, so that the movable end of the telescopic column 281 can be fixed.

The second knob 353 drives the second trapezoidal lead screw 351 to rotate, so that the second trapezoidal lead screw 351 drives the movable block 352 threadedly connected thereto to slide inside the groove 33, thereby driving the movable plate 34 at the top to slide to a suitable position, and limiting the steel structures of different cross-sections and sizes to prevent the steel structures from moving at will during assembly. The elastic pads 36 on one side of the fixed plate 32 and the movable plate 34 can play a role of buffering and shock absorption. The fixed seat 31 is installed on the base 10 through the fastening bolts on the mounting seat 37. After the fixed seat 31 is removed, the base 10 can still be used for assembling large box girders.

[0024] This application can explain its functional principle through the following operation methods:

[0025] When in use, multiple bases 10 are placed according to the position where the steel truss needs to be assembled, and the center line of the base 10 is aligned with the ground projection line of the steel truss. After the position of the base 10 is determined, multiple fixing nails 284 on the connecting seat 283 at the bottom of the telescopic column 281 are inserted into the ground to fix the telescopic column 281 at the specified position, and then the height of the base 10 is adjusted according to the height of the ground at different positions so that the multiple bases 10 remain horizontal, and the first knob 27 on the fixing sleeve 21 is rotated so that the first knob 27 drives the second bevel gear 26 to rotate inside the movable groove, and the second bevel gear 26 drives the first bevel gear 25 meshing therewith to rotate, so that the first trapezoidal screw 24 drives The extension rod 22 threadedly connected thereto moves accordingly, changing the height of the base 10 at the top of the extension rod 22. The limit blocks 23 on both sides of the extension rod 22 limit the movement of the extension rod 22 to prevent the extension rod 22 from rotating with the first trapezoidal lead screw 24. When the height of the base 10 changes, the telescopic columns 281 on both sides of the bottom of the base 10 extend and retract accordingly. After the height is determined, the two adjusting bolts 282 on the outside of the telescopic columns 281 are rotated to limit the telescopic columns 281 to prevent the telescopic columns 281 from extending and retracting at will, so that the two telescopic columns 281 can assist in supporting the base 10, and cooperate with the self-locking of the first trapezoidal lead screw 24 to prevent the height of the base 10 from changing at will.

[0026] After the heights of the multiple bases 10 are adjusted to a level, the fixing base 31 is installed on the base 10 through the fastening bolts on the mounting base 37, and the steel structure is placed on the fixing base 31 at a position close to the elastic pad 36 on one side of the fixing plate 32. Then, the position of the movable plate 34 is adjusted according to the size of the steel structure, and the second knob 353 is rotated so that the second knob 353 drives the second trapezoidal screw 351 to rotate, thereby driving the movable block 352 threadedly connected thereto to slide along the groove 33, and driving the movable plate 34 on the top of the movable block 352 to move to a suitable position on the fixing base 31, and cooperate with the fixing plate 32 to limit the steel structure, so that the support device can limit the steel structures of different cross-sections and sizes to prevent the steel structure from moving at will during assembly, and the elastic pad 36 on one side of the fixing plate 32 and the movable plate 34 can play a role in buffering and shock absorption, thereby improving the stability of assembly.
