Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a splicing frame welding device for a steel box girder and a welding method thereof. Background Art

[0002] The tire frame is a kind of mold, which refers to the scaffolding that mainly bears the load and force. It is a special process equipment for facilitating the assembly and welding of mechanical equipment. It is widely used in formwork engineering, steel structure installation engineering and bridge engineering. It is different from the commonly used single and double row scaffolding. Due to the great difference in the structural form and weight of the support, the design of the tire frame is quite different. Different equipment and different processes have different forms of tire frames. In the process of bridge construction, the production of steel box girders is inseparable from the support of the tire frame, and the tire frame is also welded with various steel materials during the manufacturing process.

[0003] It should be noted that when welding the tire frame, due to the different sizes of various steels and the complex structure after welding, the welding host is often placed in a high place, and the welding cable will be pulled as the worker moves the welding gun during welding. This causes the welding host to be directly pulled down due to negligence during the specific welding operation, causing the welding host to fall to the ground. The outside of the welding host is often provided with heat dissipation holes for heat dissipation, and the environment for the tire frame construction cannot be guaranteed. Therefore, once the welding host falls to the ground, it is not only easy to cause damage to the welding host, but also cause water or a large amount of dust to enter the welding host.

[0014] A method for welding a spliced ​​tire frame of a steel box beam is performed according to the above-mentioned spliced ​​tire frame welding equipment of a steel box beam, and comprises the following steps: S1. When the cable is pulled, the clamping plate is driven to move, and the clamping plate moves in the installation box through the telescopic pull plate, and drives the buffer spring to move, and the cable is buffered by the rebound force of the buffer spring; S2. When the pulling force is large, the telescopic pull plate is driven to move excessively. The telescopic pull plate drives two extrusion push blocks to move through two follower rods. The two extrusion push blocks squeeze the other two extrusion push blocks to move, driving the driving frame to move downward. The driving frame moves through four adapter plates to drive four push frames to move, so that the push frame drives the stabilizing rod to rotate, and the stabilizing rod drives the counterweight block to rotate and unfold, so as to actively stabilize the welding host. S3. When the welding host falls, the compression sleeve is no longer squeezed, and the compression sleeve is driven to move under the expansion force of the expansion spring. The movement of the compression sleeve drives the four linkage shafts to move through the linkage frame. The linkage shaft drives the rotating push rod to rotate. The rotating push rod drives the separation partition to move through the push-pull shaft. The movement of the separation partition drives multiple plugs to disengage from multiple slots. S4. When the welding host falls and the linkage frame moves, the linkage frame drives the closing plate to move, so that the ventilation holes and the heat dissipation holes are staggered, thereby closing the heat dissipation holes. The movement of the closing plate drives the top opening rod to separate from the isolation rotating plate. Under the rebound force of the reset torsion spring, the isolation rotating plate rotates and closes the slot.

[0015] The beneficial effects of the steel box girder splicing frame welding device and the welding method thereof proposed by the present invention are: In the present invention, through the setting of the anti-pulling stabilizing structure, when the cable is pulled, the clamping plate is driven to move, and the clamping plate moves in the installation box through the telescopic pull plate, and drives the buffer spring to move. When the pulling force is not large, the rebound force of the buffer spring can play a role of buffering and reminder. However, when the pulling force is large, the telescopic pull plate moves a large distance, and the stabilizing rod drives the counterweight block to rotate and unfold, thereby increasing the ground contact area of ​​the welding host, and supporting the welding host at the same time, and further stabilizing the welding host under the weight of the four counterweight blocks to prevent the welding host from falling.

[0016] Furthermore, in the present invention, by setting an active separation structure, when the welding host is accidentally knocked over or the pulling force is too large, causing the welding host to fall, the compression sleeve is no longer squeezed, and the separation partition drives the multiple plugs to disengage from the multiple slots, thereby preventing the welding host from being electrified when it falls, thereby preventing a short circuit or even a fire.

[0017] Furthermore, in the present invention, through the setting of a synchronous isolation protection structure, when the welding host falls and the linkage frame moves, the linkage frame drives the closing plate to move, so that the ventilation holes and the heat dissipation holes are staggered, thereby achieving the closure of the heat dissipation holes. At the same time, the movement of the closing plate drives the top opening rod to disengage from the isolation rotating plate. At this time, under the rebound force of the reset torsion spring, the isolation rotating plate rotates and closes the slot, avoiding problems such as water and dust entering the inside when the welding host falls, thereby ensuring the safety of the welding host.

[0038] In summary, the working principle of a steel box girder splicing frame welding device provided by an embodiment of the present invention, that is, the welding method of the steel box girder splicing frame welding device using the embodiment of the present invention is: When the cable is pulled, the clamping plate 603 is driven to move, and the clamping plate 603 moves in the installation box 601 through the telescopic pull plate 602, and drives the buffer spring 604 to move. When the pulling force is not strong, the buffer and reminder effects can be achieved through the rebound force of the buffer spring 604. However, when the pulling force is large, the telescopic pull plate 602 moves a large distance, and the telescopic pull plate 602 drives the two extrusion push blocks 613 to move through the two follower rods 612. The two extrusion push blocks 613 squeeze the other two extrusion push blocks 613 to move, thereby driving the drive frame 609 to move downward, driving The frame 609 moves vertically in the lifting slot 615 through the lifting frame 614. The driving frame 609 moves through the four adapter plates 610 to drive the four pushing frames 608 to move, so that the pushing frames 608 push the stabilizing rod 606 to rotate. The stabilizing rod 606 rotates on the installation shaft 611 and drives the rebound torsion spring 617 to be stressed. The stabilizing rod 606 drives the counterweight block 607 to rotate and unfold, thereby increasing the ground contact area of ​​the welding host 1 and supporting the welding host 1 at the same time. In addition, the welding host 1 is further stabilized under the weight of the four counterweight blocks 607 to prevent the welding host 1 from falling. In addition, if the welding host 1 is accidentally knocked over or the pulling force is too large, causing the welding host 1 to fall, the compression sleeve 708 is no longer squeezed, and under the expansion force of the expansion spring 710, the compression sleeve 708 is driven to move, and the compression sleeve 708 moves through the linkage frame 706 to drive the four linkage shafts 707 to move, and the linkage shaft 707 drives the rotating push rod 703 to rotate, and at the same time, the linkage shaft 707 slides in the rotating push rod 703, and the rotating push rod 703 drives the separation partition 701 to move through the push-pull shaft 704, and the push-pull shaft 704 slides in the push-pull groove 705. The movement of the separation partition 701 drives multiple plugs 2 to disengage from multiple slots 3, thereby avoiding the problem of short circuit or even fire when the welding host 1 is charged when it falls; Furthermore, when the welding host 1 falls and causes the linkage frame 706 to move, the linkage frame 706 drives the closing plate 806 to move, so that the ventilation holes 807 are staggered with the heat dissipation holes 4, thereby closing the heat dissipation holes 4. At the same time, the closing plate 806 moves to drive the top rod 805 to disengage from the isolation rotating plate 801. At this time, under the rebound force of the reset torsion spring 804, the isolation rotating plate 801 rotates and the slot 3 is closed, thereby avoiding problems such as water and dust entering the interior when the welding host 1 falls.
