[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In one embodiment of the present invention:

[0026] like Figure 1 and Figure 2 As shown, the bottom-mounted driving device 2 includes: a fixed base 201 connected to the base 1; a first driving member 202 connected to the fixed base 201; the first driving member 202 is an electric telescopic rod; a top frame 203 connected to the side of the fixed base 201 away from the base 1; at least two limiting slide grooves 204 disposed inside the top frame 203; and at least two through slots 205 disposed inside the top frame 203.

[0027] The two steel structural components to be welded are placed inside the two side limiting frame assemblies 4, with the side to be welded in the position of the circumferential welding assembly 8. Then, the height of the two steel structural components is adjusted by the lifting assembly 5, and the steel structural components are limited and fixed by the external steel structure limiting assembly 7. Then, the external steel structure limiting assembly 7 is locked and limited by the pressing assembly 6, which further improves the stability of the steel structural components. Then, driven by the first driving component 202, the two side limiting frame assemblies 4 and the steel structural components inside them move in opposite directions. When the two steel structural components to be welded are in contact, directional or dynamic welding can be performed by the circumferential welding assembly 8.

[0028] In this application, the first driving component 202 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the limiting frame component 4. No specific limitation is made here.

[0029] In one embodiment of the present invention:

[0030] like Figure 1 and Figure 3 As shown, the limiting frame assembly 4 includes: a connecting plate frame 401, which is slidably connected to the base 1 through the through groove 205 and connected to the end of the first driving member 202 away from the fixed seat 201; a limiting frame 402, which is connected to the side of the connecting plate frame 401 away from the base 1; at least three connecting grooves 403, which are disposed inside the limiting frame 402; a limiting groove frame 404, which is disposed inside the connecting grooves 403 and fixedly connected to the connecting plate frame 401; and a sliding seat 405, which is fixedly connected at one end to the bottom side of the limiting frame 402 and slidably connected at the other end to the top side of the top frame 203.

[0031] The external steel structure limiting component 7 can work with the limiting slot frame 404 to limit movement outside the limiting frame 402, thereby limiting and fixing the irregular steel structure according to the shape of the internal irregular steel structure. When the first driving component 202 runs, it can drive the connecting plate frame 401 and the slide 405 to move synchronously.

[0032] In one embodiment of the present invention:

[0033] like Figure 1 As shown, the lifting assembly 5 includes: a second driving member 501, which is internally connected to the limiting frame 402; the second driving member 501 is an electric telescopic rod; and a top plate 502, which is connected to the second driving member 501.

[0034] The limiting frame 402 has openings on both sides. The steel structural component to be welded is placed on the top plate 502. The welding ends of the steel structural component on both sides protrude to the outside of the limiting frame 402. According to the required welding position, the top plate 502 is lifted and adjusted under the drive of the second drive component 501, thereby adjusting the height of the steel structural component. Then, it is limited and fixed by several external steel structure limiting components 7.

[0035] In this application, the second driving component 501 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the top plate 502. No specific limitation is made here.

[0038] Once the positions of several external steel structure limiting components 7 are determined, the pressure plate 602 can be moved downward under the drive of the third driving component 601, so that the anti-slip plate 603 abuts against the top side of the external steel structure limiting components 7, thereby completing the limiting and fixing of several external steel structure limiting components 7.

[0039] In this application, the second driving component 601 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the pressure plate 602. No specific limitation is made here.

[0040] In one embodiment of the present invention:

[0041] like Figure 1 and Figure 4 As shown, the external steel structure limiting assembly 7 includes: a plurality of fourth driving members 701, the fourth driving members 701 being connected to the connecting plate frame 401; the fourth driving members 701 are electric telescopic rods; an external limiting ring frame 702, the external limiting ring frame 702 being connected to the end of the fourth driving members 701 away from the connecting plate frame 401; and a first limiting frame 703, one side of the first limiting frame 703 being connected to the interior of the external limiting ring frame 702, and the other side being connected to the limiting groove frame. 404 sliding connection; second limiting frame 704, one side of the first limiting frame 703 is connected to the inside of the outer limiting ring frame 702, and the other side is slidably connected to the limiting groove frame 404; fifth driving member 705, one end of the fifth driving member 705 is connected to the inside of the outer limiting ring frame 702; the fifth driving member 705 is an electric telescopic rod; anti-slip ball 706, the anti-slip ball 706 is connected to the end of the fifth driving member 705 away from the outer limiting ring frame 702;

[0042] The anti-slip ball 706 is made of rubber. When the height of the steel component inside the limiting frame 402 is adjusted, the positions of several external limiting ring frames 702 are adjusted under the drive of several fifth driving components 705. When the external limiting ring frame 702 moves, the first limiting frame 703 and the second limiting frame 704 can move inside the limiting groove frame 404 at the corresponding positions, further improving the movement stability of the external limiting ring frame 702. Then, according to the shape of the irregular steel structure, several fifth driving components 705 at appropriate positions are selected to drive the anti-slip ball 706 to move towards the side closer to the steel structure, so that the anti-slip ball 706 abuts and presses against the irregular steel structure, completing the multi-point clamping and limiting of the irregular steel structure.

[0043] In this application, the fourth driving component 701 is not limited to an electric telescopic pole; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the external limiting ring 702. No specific limitation is made here. In this application, the fifth driving component 705 is not limited to an electric telescopic pole; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the anti-slip ball 706. No specific limitation is made here.

[0044] In one embodiment of the present invention:

[0045] like Figure 1 and Figure 5 As shown, the circumferential welding assembly 8 includes: a sixth driving member 801, which is connected to the top frame 203; the sixth driving member 801 is an electric telescopic rod; a seventh driving member 802, which is slidably connected to the top frame 203 and slidably connected to the limiting slide groove 204, and is connected to the sixth driving member 801; the seventh driving member 802 is an electric telescopic rod; a connecting frame 803, which is connected to the side of the seventh driving member 802 away from the top frame 203; a circumferential frame 804, which is connected to the connecting frames 803 on both sides; an eighth driving member 805, which is internally meshed with the circumferential frame 804; the eighth driving member 805 is an electric gear slide; and a welding gun 806, which is connected to the eighth driving member 805.

[0046] A rack groove (not shown in the figure) is provided inside the circumferential frame 804. After the steel structural members on both sides are aligned and fixed, the position of the welding gun 806 is adjusted by the eighth driving member 805. Under the drive of the sixth driving member 801 and the seventh driving member 802, the position and height of the circumferential frame 804 are adjusted so that the welding gun 806 contacts the position to be welded on both sides of the steel structure and the welding of the steel structural members on both sides is carried out by the welding gun.

[0047] In this application, the sixth driving component 801 is not limited to an electric telescopic pole; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the seventh driving component 802. No specific limitation is made here.

[0048] The working principle of this invention is as follows: Two steel structural components to be welded are placed inside the side limiting frame assemblies 4, with the side to be welded positioned at the circumferential welding assembly 8. The height of the steel structural components is then adjusted by the lifting assembly 5. The external steel structure limiting assembly 7 secures and limits the steel structural components, and the pressing assembly 6 locks and limits the external steel structure limiting assembly 7, further improving the stability of the steel structural components. Then, driven by the first driving component 202, the side limiting frame assemblies 4 and their internal steel structural components move in opposite directions. When the two steel structural components are at the welding positions, directional or dynamic welding can be performed through the circumferential welding assembly 8. The first driving component 202 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can achieve the movement and adjustment of the limiting frame assemblies 4. No specific limitations are made here. The limiting component 7 can cooperate with the limiting slot frame 404 to limit movement outside the limiting frame 402, thereby limiting and fixing the irregular steel structure according to the shape of the internal irregular steel structure. When the first driving component 202 runs, it can drive the connecting plate frame 401 and the slide 405 to move synchronously. The limiting frame 402 has openings on both sides, and the steel structure to be welded is placed on the top plate 502. The welding ends of the steel structure on both sides protrude to the outside of the limiting frame 402. According to the required welding position, under the drive of the second driving component 501, the top plate 502 is lifted and adjusted, thereby adjusting the height of the steel structure. Then, it is limited and fixed by several external steel structure limiting components 7. The second driving component 501 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the top plate 502. No specific limitation is made here.

[0049] Once the positions of several external steel structure limiting components 7 are determined, the pressure plate 602 can be moved downwards under the drive of the third driving component 601, causing the anti-slip plate 603 to abut against the top side of the external steel structure limiting components 7, thus completing the limiting and fixing of the several external steel structure limiting components 7. The second driving component 601 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the pressure plate 602. No specific limitation is made here. The anti-slip ball 706 is made of rubber. When the height of the internal steel components of the limiting frame 402 is adjusted, the pressure plate 602 moves downwards under the drive of several fifth driving components 705. Driven by the mechanism, the positions of several external limiting ring frames 702 are adjusted. When the external limiting ring frames 702 move, the first limiting frame 703 and the second limiting frame 704 can move inside the limiting groove frame 404 at the corresponding positions, further improving the movement stability of the external limiting ring frames 702. Then, according to the shape of the irregular steel structure, several fifth driving members 705 at appropriate positions are selected to drive the anti-slip ball 706 to move towards the side closer to the steel structure, so that the anti-slip ball 706 abuts and presses against the irregular steel structure, completing the multi-point clamping and limiting of the irregular steel structure. The fourth driving member 701 is not limited to the electric telescopic rod device, but can also be used... The external limiting ring frame 702 can be moved and adjusted using a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can achieve the movement adjustment of the external limiting ring frame 702. No specific limitation is made here. In this application, the fifth driving component 705 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can achieve the movement adjustment of the anti-slip ball 706. No specific limitation is made here. A rack groove (not shown in the figure) is provided inside the circumferential frame 804. After the steel structural members on both sides are aligned and fixed, the position of the welding gun 806 is adjusted by the eighth driving component 805, driven by the sixth driving component 801 and the seventh driving component 802. Under the influence of the movement, the position and height of the circumferential frame 804 are adjusted so that the welding gun 806 contacts the welding positions of the steel structures on both sides. The welding gun is used to weld the steel structural components on both sides. The sixth driving component 801 is not limited to an electric telescopic pole. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the seventh driving component 802. No specific limitation is made here. In this application, the seventh driving component 802 is not limited to an electric telescopic pole. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the movement and adjustment of the connecting frame 803. No specific limitation is made here.

[0050] In summary, by combining the built-in steel structure limiting component 3 and the external steel structure limiting component 7, multi-point limiting of irregular steel structure components can be achieved, improving the fixing flexibility of irregular steel structure components. At the same time, the circumferential welding component 8 is provided, further improving the welding flexibility.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
