Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a fast welding device for a steel cage used in bridge construction. Background Art

[0002] The steel cage is an indispensable structural component in construction projects and plays a key role in the construction of various concrete structures. It is mainly composed of longitudinal steel bars and transverse stirrups connected by welding or binding. The longitudinal steel bars are distributed on the outside of the steel cage and bear the main tensile force of the structure, ensuring that when the concrete structure is subjected to external forces, it can effectively resist the tensile force and prevent the structure from cracking. The transverse stirrups surround the longitudinal steel bars, like a solid "skeleton", which not only fixes the longitudinal steel bars to prevent them from shifting during the concrete pouring process, but also constrains the concrete and enhances the compressive capacity of the structure.

[0003] During the assembly process before welding the steel cage, inaccurate steel bar positioning will greatly reduce the strength and stability of the structure. When the longitudinal steel bar positioning deviation is not in the optimal designed stress-bearing position, when the concrete structure is subjected to external forces, such as earthquake forces, wind forces and other loads, the steel bar cannot effectively exert its tensile properties, resulting in local stress concentration in the structure, weakening the overall bearing capacity, and increasing the risk of building collapse. Secondly, it affects the quality of concrete pouring. Inaccurately positioned steel bars will change the internal space form of the steel cage, hinder the flow of concrete during the pouring process, and result in loose pouring, such as defects such as honeycombs and holes, which reduce the bond strength between concrete and steel bars and further damage the integrity of the structure.

By setting a spring 718, the piston 715 can be squeezed, so that the rubber pad 717 is always subjected to an extrusion force toward the steel bars of the steel cage, so that the internal space of the steel cage can be supported to prevent the steel cage from deforming. The outer surface of the rotating box 75 is provided with a square groove 76, and the square groove 76 on the outer surface of the rotating box 75 is fixedly connected with an extruder The squeezing mechanism 77 comprises a ventilating tube 771, the ventilating tube 771 is fixedly connected to the square groove 76, a first round tube 772 is passed through the end of the ventilating tube 771, a first sliding rod 773 is slidably connected to the inner cavity of the first round tube 772, a connecting strip 774 is fixedly connected to the end of the first sliding rod 773, a squeezing strip 775 is fixedly connected to the outer surface of the connecting strip 774, a connecting frame 776 is fixedly connected to the outer surface of the first round tube 772, a second round tube 777 is fixedly connected to the end of the connecting frame 776, a second sliding rod 778 is slidably connected to the inner cavity of the second round tube 777, The end of the second sliding rod 778 is fixedly connected to the outer surface of the connecting strip 774. By setting up the extrusion mechanism 77, the inner cavity of the steel cage can be squeezed and supported, so that the inner cavity of the steel cage can remain cylindrical, preventing the steel cage from deforming during welding. By setting up the air vent 771, the air flow can enter the inner cavity of the rotating box 75, and then enter the inner cavity of the air vent 771, and finally make the first sliding rod 773 slide in the inner cavity of the first circular tube 772, so as to achieve the effect of squeezing the extrusion strip 775 against the inner wall of the steel cage. By setting up the second circular tube 777 and the second sliding rod 778, the movement of the extrusion strip 775 can be made more stable.

[0028] Working principle: When in use, the operator inserts the end of the steel bar in the steel cage frame into the inner cavity of the positioning frame 712, and makes the end of the steel bar tightly squeezed against the anti-slip gasket 713. After several steel bars are positioned, the circular steel ring is inserted between several steel bars. Then, the operator rotates the handle 617 to make the opening of the bend 616 face upward, and the end of the third telescopic tube 711 is sleeved in the inner cavity of the bend 616. Then, the servo motor 67 is connected to the power supply and the switch is turned on, so that the second rotating rod 68 drives the worm 69 and the third rotating rod 610 to rotate, and then the fan plate 614 rotates to allow the outside air to enter the inner cavity of the connecting box 611, and finally flows through the bend 616 to the space formed by the rotating box 75 and the rotating shell 74. After the air flow continues to enter, as the air pressure increases, the piston 715 drives the moving column 716 and the rubber pad 717 to squeeze the inner wall of the steel cage, so that the shape of the inner cavity of the steel cage is supported; Then, the threaded ring 62 is rotated to move the threaded ring 62 upward until the worm 69 is meshed with the worm wheel 79, and the electric welder 43 is connected to the power supply and turned on, so that the electric welder 43 can contact the contact point between the steel bar and the circular steel bar ring. When the worm wheel 79 rotates at a small angle, the welding position of the electric welder 43 is controlled, and finally the effect of welding one steel bar ring with multiple steel bars is achieved; After one circle of welding is completed, the operator rotates the threaded ring 62 in the opposite direction so that the worm 69 is not engaged with the worm wheel 79, and then rotates the handle 617 to make the end of the bent pipe 616 contact the end of the first telescopic tube 46. Then, air enters the inner cavity of the second telescopic tube 47 through the first connecting tube 45, and expands the second telescopic tube 47, and finally moves the sliding block 42 in the inner cavity of the track frame 41 until the electric welder 43 moves to the position of the next steel bar ring, and then disconnects the first telescopic tube 46 and the bent pipe 616. Then, the steel cage rotation operation is repeated to weld multiple steel bar rings and multiple steel bars into one.
