Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a device for steel structure welding. Background Art

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

[0003] The existing steel pipe is usually welded by multiple steel pipes. When welding multiple steel pipes, users generally use welding devices. For example, the existing patent with announcement number CN215034850U discloses a steel structure welding tool, which places the steel pipe on two sets of fixed clamping plates, and then uses two sets of turntables to rotate two sets of first screws, and the two sets of first screws are screwed with two sets of first screw rings. The two sets of first screws drive the two sets of moving clamping plates to move downward, and the two sets of moving clamping plates clamp and fix the steel pipes on the two sets of fixed clamping plates. Then, according to the steel pipes to be welded on the steel structure The position of the steel structure is used to make the rotating rod rotate on the rotating seat, so as to adjust the angle of the steel pipe. When the angle of the steel pipe reaches the required angle, the rotating rod is fixed by the locking device, and then the lifting rod is made to slide in the lifting tube to drive the connecting block to move upward as a whole. When the position of the steel pipe corresponds to the position to be welded of the steel structure, the lifting rod is fixed by the locking device, and then the welding device is used to weld the steel pipe to the steel structure. By setting up this equipment, a lot of manpower can be saved, and the steel pipe can also be fixed, which improves the stability of the steel pipe and also improves its welding effect.

[0004] However, in the above technical solution, although the steel pipe can be tightened and fixed by two groups of movable clamping plates and two groups of fixed clamping plates, if the user needs to clamp steel pipes of different diameters, due to the fixed spacing in the middle of the cross frame, the maximum spacing between the movable clamping plates and the fixed clamping plates is limited, making it difficult for the user to clamp and fix steel pipes of different diameters. Therefore, the utility model aims to provide a welding device capable of clamping steel pipes of different diameters. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figures 1 to 3 According to an embodiment of the utility model, a technical solution is provided: a device for welding a steel structure, comprising a pipe body 1, a base plate 2 and a support plate 3 arranged on the base plate 2, a bearing plate 4 being vertically arranged on the support plate 3, and also comprising a pressure plate 5, an adjusting mechanism 6 being arranged between the bearing plate 4 and the pressure plate 5, the adjusting mechanism 6 being used to drive the pressure plate 5 to move relative to the bearing plate 4 to increase or decrease the distance between the pressure plate 5 and the bearing plate 4; and a tightening mechanism 8, which is arranged between the pressure plate 5 and the adjusting mechanism 6 and is used to tighten the pressure plate 5 to the bearing plate 4.

[0026] When the user needs to clamp pipe bodies 1 of different diameters using the steel structure welding device of the above structure, the adjusting mechanism 6 is first used to adjust the spacing between the pressing plate 5 and the supporting plate 4 to a distance suitable for placing the pipe body 1, and then the pressing mechanism 8 is used to press the pressing plate 5 against the pipe body 1 to prevent the pipe body 1 from vibrating, and then the welding operation can be carried out, which is convenient for the user to clamp and fix the pipe bodies 1 of different diameters.

[0027] In this embodiment, the adjustment mechanism 6 includes an adjustment rod 9, which is relatively perpendicular to the supporting plate 4. The adjustment rod 9 movably passes through the supporting plate 4. A locking mechanism 7 is provided between the adjustment rod 9 and the supporting plate 4. The locking mechanism 7 is used to fix the adjustment rod 9 and the supporting plate 4 relative to each other to limit or allow the adjustment rod 9 to move relative to the supporting plate 4. When the user needs to adjust the distance between the pressure plate 5 and the supporting plate 4, the user pulls or presses the adjustment rod 9 to increase or decrease the distance between the pressure plate 5 and the supporting plate 4. When the distance between the pressure plate 5 and the supporting plate 4 is adjusted to the user's preset distance, the locking mechanism 7 is used to fix the adjustment rod 9 and the supporting plate 4 relative to each other, thereby completing the adjustment of the distance between the pressure plate 5 and the supporting plate 4.

[0028] Alternatively, the adjustment mechanism 6 can also be set to other suitable structures or forms. For example, the adjustment rod 9 can be replaced with a pneumatic rod, and the pressure plate 5 can be driven to move relative to the supporting plate 4 by pulling or pressing the pneumatic rod to increase or decrease the distance between the pressure plate 5 and the supporting plate 4. The pneumatic rod has a locking mechanism 7, and a lifting valve is provided at the top of the pneumatic rod. The length of the pneumatic rod can be adjusted by pressing the lifting valve. This is the prior art and will not be described in detail.

[0029] In this embodiment, the locking mechanism 7 includes a plurality of locking holes 11 and a locking rod 10 which are spaced apart along the length direction of the adjusting rod 9. The locking rod 10 movably penetrates the supporting plate 4 and extends into the locking hole 11. When the user needs to relatively fix the supporting plate 4 and the adjusting rod 9, the locking rod 10 is movably inserted into the supporting plate 4 until a portion of the locking rod 10 is inserted into the locking hole 11 to limit the movement of the adjusting rod 9 relative to the supporting plate 4.

[0030] Alternatively, the locking mechanism 7 can also be set to other suitable structures or forms, for example, using a bolt to be threadedly connected to the bearing plate 4, screwing the bolt into the bearing plate 4 to abut the adjusting rod 9 to limit the movement of the adjusting rod 9 relative to the bearing plate 4.

[0031] In this embodiment, the tightening mechanism 8 includes a fixed plate 12, an abutment rod 13 and a spring 14. The fixed plate 12 is fixed on the adjusting rod 9. The abutment rod 13 movably passes through the fixed plate 12. The pressure plate 5 is fixed at the bottom of the abutment rod 13. A spring 14 is sleeved on the adjusting rod 9. The spring 14 is arranged between the pressure plate 5 and the fixed plate 12. When the user needs to use the pressure plate 5 to press the tube body 1 against the supporting plate 4, the abutment rod 13 is pulled first to make the space between the pressure plate 5 and the supporting plate 4 suitable for placing the tube body 1, and then the pressure plate 5 is released. At this time, the pressure plate 5 will be elastically abutted against the tube body 1 by the spring 14 to abut the tube body 1 against the supporting plate 4.

[0032] Alternatively, the pressing mechanism 8 may also be configured as other suitable structures or forms, for example, the contact rod 13 may be replaced with a screw and threadedly connected to the fixing plate 12 , and the pressing plate 5 may be driven to press against the tube body 1 by rotating the screw.

[0033] In this embodiment, a crescent-shaped clamping opening 15 is provided at the bottom of the pressure plate 5; when the user presses the pressure plate 5 against the tube body 1, the crescent-shaped clamping opening 15 can increase the contact area of ​​the pressure plate 5 with the tube body 1, thereby increasing the friction force of the pressure plate 5 with the tube body 1 and preventing the tube body 1 from detaching from the pressure plate 5.

[0034] In this embodiment, a friction-enhancing sleeve 16 is disposed in the clamping opening 15 ; when the user presses the pressing plate 5 against the tube body 1 , the friction-enhancing sleeve 16 increases the friction force of the pressing plate 5 on the tube body 1 , further preventing the tube body 1 from detaching from the pressing plate 5 .

[0035] Working principle: When the user needs to clamp the tube body 1 of different diameters, first pull or press the adjustment rod 9 to increase or decrease the distance between the pressure plate 5 and the carrier plate 4. When the distance between the pressure plate 5 and the carrier plate 4 is adjusted to the user's preset distance, the locking rod 10 is movably inserted into the carrier plate 4 until part of the locking rod 10 is inserted into the locking hole 11 to limit the movement of the adjustment rod 9 relative to the carrier plate 4. The distance between the pressure plate 5 and the carrier plate 4 can be adjusted, and then the contact rod 13 is pulled to make the space between the pressure plate 5 and the carrier plate 4 suitable for placing the tube body 1, and then the pressure plate 5 is released. At this time, The pressure plate 5 will be elastically abutted against the tube body 1 by the spring 14 to abut the tube body 1 against the supporting plate 4 to prevent the tube body 1 from vibrating. Finally, the welding operation is performed to facilitate the user to clamp and fix the tube bodies 1 of different diameters; when the user presses the pressure plate 5 against the tube body 1, the crescent-shaped clamping opening 15 can increase the contact area of ​​the pressure plate 5 on the tube body 1 to increase the friction force of the pressure plate 5 on the tube body 1 and prevent the tube body 1 from detaching from the pressure plate 5; when the user presses the pressure plate 5 against the tube body 1, the friction increasing sleeve 16 will increase the friction force of the pressure plate 5 on the tube body 1 to further prevent the tube body 1 from detaching from the pressure plate 5.
