Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a steel structure welding machine for prefabricated buildings. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. A prefabricated steel structure is a steel structure component that can be assembled on site for steel structures. When producing prefabricated steel structures, a welding device is usually required to weld and fix the splicing between steel materials.

[0003] After searching, Chinese Patent CN217799755U was retrieved and announced a steel structure welding device for prefabricated buildings. Through the combined use of a base, a frame, an electric slide rail, a first electric push rod, a housing, a welding head, a suction hood, a fan, a purification box, an activated carbon adsorption net, an air filter, a first hose, a water tank, a condenser, a hydraulic cylinder, a cooling plate, a water pump, a second hose, a circulation pipe and a third hose, it solves the problems that in the process of using the existing steel structure welding device for prefabricated buildings, it is not convenient to purify the fumes generated during welding, which is easy to cause harm to workers, and it is not convenient to cool the steel structure after welding, affecting the working efficiency of the welding device and reducing the practicability of the welding device. It can be seen that what this patent realizes is the purification of the fumes generated during welding and the cooling of the steel structure. Since this patent uses an electric slide rail to drive the horizontal movement of the welding head for welding, aiming at welding in a straight line position, and the shape of the steel structure is not just one kind, the docking position between the steel structures may be an arc or the welding position is not a plane, resulting in the inapplicability of the horizontally moving welding head. Therefore, a steel structure welding machine for prefabricated buildings is proposed. Content of the Utility Model

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3 , an assembly type building steel structure welding machine, including a body 1 and a steel beam 2. A surrounding frame 3 is fixedly installed on the top of the body 1. An installation block 4 is fixedly installed on the top of the body 1 and inside the surrounding frame 3. A connecting cylinder 5 is fixedly installed on the installation block 4. The output end of the connecting cylinder 5 is fixedly installed with a sliding table 6. When the connecting cylinder 5 expands and contracts, it drives the sliding table 6 to move back and forth, and then sends the steel beam 2 to the welding position for welding or sends out the welded steel beam 2. A slide rail 9 slidably connected to the sliding table 6 is fixedly installed on the top of the body 1 for supporting and guiding the sliding table 6. A drag chain 10 connected to the sliding table 6 is installed on the top of the body 1.

[0019] Among them, a carrier table 11 is fixedly installed on the top of the sliding table 6. The steel beam 2 is placed on the carrier table 11. A positioning column 12 passing through the carrier table 11 is fixedly installed on the top of the sliding table 6. After the steel beam 2 is placed on the carrier table 11, it is blocked by the positioning column 12, restricting the lateral movement and longitudinal movement of the steel beam 2. An installation frame 13 is fixedly installed on the outer surface of the carrier table 11, and the shape of the installation frame 13 is an inverted T shape.

[0020] In addition, a clamping assembly 14 for fixing the steel beam 2 is provided on the vehicle platform 11 and the mounting bracket 13. The clamping assembly 14 includes a moving cylinder 141, a support rod 142, a pressing rod 143, and a pressing block 144. The moving cylinder 141 is fixedly installed at the bottom of the mounting bracket 13. The support rod 142 is rotatably connected to the side wall of the mounting bracket 13. The pressing rod 143 is hinged to the output end of the moving cylinder 141 and is also hinged to the side wall of the support rod 142. The pressing block 144 is fixedly installed at the bottom of the pressing rod 143, and the pressing block 144 is cylindrical in shape.

[0021] When this embodiment is in use, the moving cylinder 141 extends, pushing the pressing rod 143 to move around the bottom of the support rod 142, driving the pressing block 144 to move towards the upper surface of the steel beam 2 to clamp and fix the steel beam 2. When the moving cylinder 141 contracts, it pulls the support rod 142 to move around the bottom of the support rod 142, causing the pressing rod 143 to tilt, so that the pressing block 144 disengages from the upper surface of the steel beam 2, thereby loosening the steel beam 2.

[0022] Furthermore, a shielding assembly 15 is provided on the surrounding frame 3. The shielding assembly 15 includes a telescopic cylinder 151 and a shielding plate 152. The telescopic cylinder 151 is fixedly installed on the rear side wall of the surrounding frame 3. The shielding plate 152 is fixedly installed at the output end of the telescopic cylinder 151 and is slidably connected to the surrounding frame 3. When the telescopic cylinder 151 contracts, it pulls the shielding plate 152 to move upward, which is beneficial for allowing the steel beam 2 to enter the interior of the surrounding frame 3 for welding work or pulling out the welded steel beam 2. When the telescopic cylinder 151 extends, it pushes the shielding plate 152 to move downward, blocking the flying metal debris from flying out of the surrounding frame 3 during welding and hurting people, thus improving the safety during the welding of the steel beam 2.

[0023] Please refer to Figures 1-2 On the top of the machine body 1 and outside the connecting cylinder 5, an adjustment assembly 7 is provided to facilitate welding the butt joint of the steel beam 2 and the steel beam 2. The adjustment assembly 7 includes a support motor 71, a biaxial motor 72, a swing arm 73, a servo motor 74, a driving frame 75, a servo motor 76, a connecting arm 77, and a rotating motor 78. The support motor 71 is fixedly installed on the top of the machine body 1. The biaxial motor 72 is fixedly installed on the output shaft of the support motor 71. The swing arms 73 are fixedly installed on the output shafts on both sides of the biaxial motor 72, and the number of swing arms 73 is two. The servo motor 74 is fixedly installed on the side wall of the swing arm 73. The driving frame 75 is fixedly installed on the output shaft of the biaxial motor 74. The driving frame 75 is concave in shape. The servo motor 76 is fixedly installed on the inner side wall of the driving frame 75. The connecting arm 77 is fixedly installed on the output shaft of the servo motor 76. The rotating motor 78 is fixedly installed on the inner side wall of the connecting arm 77, and a laser welding machine 8 is fixedly installed on the output shaft of the rotating motor 78.

[0024] In the use of this embodiment, the support motor 71, the biaxial motor 72, the servo motor 74, the servo motor 76 and the rotary motor 78 are started to drive the laser welding machine 8 to rotate in all directions, so that the laser welding machine 8 contacts the butt joint of the steel beams 2 and the steel beams 2, and the laser welding machine 8 is started to weld between the steel beams 2 and the steel beams 2.
