The existing welding equipment is not convenient for welding different surfaces of bridge steel frames of different diameters after clamping. It is often necessary to manually flip the bridge steel frames, which makes welding very inconvenient. For this reason, we proposed a steel frame welding equipment. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-7A steel frame welding device includes a welding device 2 and a gear plate 9. The front and rear ends of the gear plate 9 are both provided with a turntable 10. A support frame 1 is set between the two sides of the gear plate 9. The support frame 1 is provided with an adjustment structure for driving the welding device 2 to move left and right and up and down. The turntable 10 close to the welding device 2 is fixedly connected to the gear plate 9 through a plurality of support columns, and the rear end of the gear plate 9 is rotatably connected to another turntable 10. The turntable 10 is fixed by a support seat, and a clamping groove 2 is provided at the central axis position of the gear plate 9 and the turntable 10. 1. A conveyor belt for conveying the bridge steel frame is arranged at the rear side of the turntable 10 at the rear side. The conveyor belt is not shown in the figure in this article. The bridge steel frame is conveyed into the clamping groove 21 by the conveyor belt. A rotating structure for driving the rotation of the gear plate 9 is arranged on one side. Two movable plates 13 are arranged on the turntable 10 near the welding equipment 2 and on the gear plate 9 around the clamping groove 21. A movable structure for adjusting the width according to the diameter of the bridge steel frame is arranged on both sides between the two movable plates 13. A pushing structure for driving the movable plate 13 to move is arranged on one side of one of the movable plates 13.

[0029] Furthermore, the adjustment structure includes a gear 4 and a rack 5. A motor 3 is fixedly installed at the center position of the support frame 1. The output end of the motor 3 passes through the support frame 1 and is fixedly connected to the gear 4. The bottom end of the gear 4 is meshed and connected with the rack 5. A cylinder 8 is fixedly installed between the bottom end of the rack 5 and the welding equipment 2. The rotation of the motor 3 drives the gear 4 to rotate, so that the gear 4 pushes the rack 5 to slide on the support frame 1, so that the welding equipment 2 can be moved to the place where the bridge steel frame needs to be welded, and the height of the welding equipment 2 is adjusted by the cylinder 8 to weld the bridge steel frame.

[0030] Furthermore, a slide bar 6 is fixedly installed on one side of the rack 5 of the support frame 1, and a slide groove 7 is opened at a position corresponding to the slide bar 6 on the support frame 1. The slide bar 6 is slidably connected in the slide groove 7. The cross-sections of the slide bar 6 and the slide groove 7 are both trapezoidal, which increases the contact area between the slide bar 6 and the slide groove 7, thereby increasing the friction force of the rack 5 during the sliding process, thereby making the movement process of the welding equipment 2 more stable.

[0031] Furthermore, the rotating structure includes gear 2 11, one side of the gear plate 9 is meshingly connected with gear 2 11, and the rear side of gear 2 11 is fixedly installed with motor 2 12, and motor 2 12 provides supporting force through the support seat. When it is necessary to weld the other side of the bridge steel frame, there is no need to manually flip it over, and it is only necessary to start motor 2 12, and drive gear 2 11 to rotate through motor 2 12. The gear plate 9 is rotated through the meshing relationship, so that the bridge steel frame can be flipped at any angle for welding.

[0032] Furthermore, grooves are provided on the opposite sides of the movable plate 13, and a clamping wheel 17 is rotatably connected in the groove. The clamping wheel 17 is cylindrical, and the clamping surface of the bridge steel frame is clamped more stably without clamping slippage and abrasion. The four clamping wheels 17 on the gear plate 9 and the turntable 10 just surround the clamping groove 21, and clamp the bridge steel frame from all sides.

[0033] Furthermore, the moving structure includes gear three 14, rack two 15 and rack three 16. The two ends of the moving plate 13 located on the outermost side away from the pushing structure are fixedly installed with rack two 15, and the two ends of the other moving plate 13 close to the inner side are fixedly installed with rack three 16, and the other ends of rack two 15 and rack three 16 pass through and slide in the other moving plate 13, and the adjacent rack two 15 are meshedly connected with gear three 14 between the rack three 16. The bottom end of gear three 14 is rotatably connected to the gear disk 9 or the turntable 10, and the two reciprocating screws 18 are started. The reciprocating screws 18 are rotated to push the moving plate 13 on the same side thereof to move toward the direction of the bridge steel frame, thereby pushing the rack three 16 on the moving plate 13 to slide in the other moving plate 13, and the rack two 15 is driven to move by the gear three 14, so that the two moving plates 13 move toward the bridge steel frame until the four clamping wheels 17 clamp the bridge steel frame.

[0034] Furthermore, the bottom end of the movable plate 13 is located on both sides of the upper and lower ends of the clamping groove 21, and a slide groove 20 is opened. The gear plate 9 and the corresponding turntable 10 are fixedly installed with a slide bar 19. The movable plate 13 is slidably connected to the slide bar 19 through the slide groove 20. Through the setting of the slide bar 19, the movable plate 13 has support force during sliding and the sliding is more stable.

[0035] Furthermore, the driving structure includes a reciprocating screw 18, which is fixedly mounted on the gear plate 9 or placed on the corresponding turntable 10. The other end of the reciprocating screw 18 passes through the interior of the moving plate 13, and the reciprocating screw 18 is threadedly connected to the contact end of the moving plate 13.

[0036] Working principle: After placing the bridge steel frame in the clamping groove 21 through the conveyor belt, start the two reciprocating screws 18, and the reciprocating screws 18 rotate to push the moving plate 13 on the same side to move toward the bridge steel frame, thereby pushing the rack three 16 on the moving plate 13 to slide into the other moving plate 13, and the gear three 14 drives the rack two 15 to move, so that the two moving plates 13 move toward the bridge steel frame. After the four clamping wheels 17 clamp the bridge steel frame, start the motor 3, and the motor 3 rotates to drive the gear one 4 to rotate, so that the gear one 4 pushes the rack one 5 to slide on the support frame 1, so that the welding equipment 2 can be moved to the place where the bridge steel frame needs to be welded, and the height of the welding equipment 2 is adjusted by the cylinder 8 to weld the bridge steel frame. When it is necessary to weld the other side of the bridge steel frame, there is no need to manually turn it over. Just start the motor two 12, and the motor two 12 drives the gear two 11 to rotate. The gear plate 9 rotates through the meshing relationship, and the bridge steel frame can be flipped at any angle for welding.
