[0002] Steel components refer to steel structural composite components that can bear and transmit loads, made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams that are cold-bent or welded and connected by connectors.

[0003] Welding of steel components is not always carried out in the production workshop. Some steel components need to be welded on the installation site. The large height difference between components causes inconvenience to welding. Usually, shims are used to support one end of the component for welding. Even with this method, there will still be a height difference at the welded end, resulting in instability at the weld. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a steel component welding support base frame: the adjusting screw is rotated by the second limiting rod, and the rotation of the adjusting screw allows for fine adjustment of one end of the component. After the fine adjustment is completed, the first limiting rod is inserted into the slot. At this time, the second limiting rod is located between the two first limiting rods, which prevents the adjusting screw from rotating due to gravity, improves the precision of the welding position, facilitates adjustment, and solves the problem of insufficient precision at the welding joint caused by the pad, resulting in instability at the welding joint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welded steel support frame includes a base, on the top outer wall of the base are equidistantly distributed columns, and the outer walls of the columns are slidably connected to a sliding frame.

[0007] Preferably, the clamping frame is threadedly connected to the clamping screw in the screw hole, and the clamping screws are rotatably connected to the outer wall of one end close to each other, and the other outer wall of the clamping plate is glued with a soft pad.

[0008] Preferably, a limiting block is welded to the bottom outer wall of the adjusting screw, and the limiting block has equidistantly distributed limiting grooves on its side outer wall.

[0009] Preferably, the top outer wall of the base has slots that are evenly distributed, and a limiting rod 1 is inserted into the slot, a limiting rod 2 is inserted into the limiting groove, and the limiting rod 2 is located between the limiting rods 1.

[0010] According to the above scheme: the second limiting rod drives the adjusting screw to rotate, and the rotation of the adjusting screw makes a fine adjustment to one end of the component. After the fine adjustment is completed, the first limiting rod is inserted into the slot. At this time, the second limiting rod is located between the two first limiting rods, which prevents the adjusting screw from rotating due to gravity, improves the precision of the welding position, and facilitates adjustment.

[0011] Preferably, the outer wall of the column has equidistantly distributed adjustment holes, and a support rod is slidably connected in the adjustment holes, with the bottom outer wall of the sliding frame placed on the outer wall of the support rod.

[0012] Preferably, a stabilizing bar is installed on the top outer wall of the column, and omnidirectional wheels are installed on the bottom outer wall of the base at equal intervals;

[0013] The above method involves adjusting the sliding frame to the desired height, then inserting the support rod into the adjustment hole of the column, and placing the sliding frame on the support rod for easy adjustment.

[0014] The beneficial effects of this utility model are as follows:

[0015] Adjust the sliding frame to the desired height, then insert the support rod into the adjustment hole of the column, and place the sliding frame on the support rod for easy adjustment;

[0016] The adjusting screw is rotated by the second limiting rod, and the rotation of the adjusting screw makes a fine adjustment to one end of the component. After the fine adjustment is completed, the first limiting rod is inserted into the slot. At this time, the second limiting rod is located between the two first limiting rods, which prevents the adjusting screw from rotating due to gravity, improves the precision of the welding position, and facilitates adjustment.

The other outer wall of the clamping plate 11 is glued with a soft pad. The rotation of the clamping screw 10 causes the clamping plate 11 and the soft pad to move closer to each other to clamp the component. The soft pad improves the clamping tightness.

[0026] A limiting block 7 is welded to the bottom outer wall of the adjusting screw 6, and the side outer wall of the limiting block 7 is provided with equally spaced limiting grooves 12. One end of the limiting rod 15 is inserted into the limiting groove 12 of the limiting block 7.

The bottom outer wall of the sliding frame 4 is placed on the outer wall of the support rod 17. The sliding frame 4 is slidably connected to the outer wall of the column 2. The support rod 17 is inserted into the adjustment hole 16 on the column 2 to limit the sliding frame 4, so as to make it easy to roughly adjust the position of the clamping frame 8 on the sliding frame 4.

[0029] A stabilizing rod 3 is installed on the top outer wall of the column 2, and omnidirectional wheels are installed on the bottom outer wall of the base 1 at equal intervals. The omnidirectional wheels on the base 1 facilitate the movement of the whole, and the stabilizing rod 3 on the top of the column 2 improves the stability of the column 2.

[0030] Working principle: In use, move the whole unit to the desired position using the casters at the bottom of the base 1, remove the support rod 17 on the column 2, adjust the sliding frame 4 to the appropriate position according to the required height, then insert the support rod 17 into the adjustment hole 16 of the column 2, place the sliding frame 4 on the support rod 17, place one end of the component in the clamping frame 8, rotate the clamping screws 10 at both ends of the clamping frame 8 to drive the soft pads on the clamping plate 11 to move closer together, clamp one end of the component after the soft pads move closer together, and after fixing, fine-tune and align one end of the component, remove the limiting rod 14 in the slot 13 on the base 1, insert one end of the limiting rod 15 into the limiting groove 12, drive the adjusting screw 6 to rotate through the limiting rod 15, and fine-tune one end of the component by rotating the adjusting screw 6. After fine-tuning, insert the limiting rod 14 into the slot. At this time, the limiting rod 15 is located between the two limiting rods 14, preventing the adjusting screw 6 from rotating due to gravity.
