Description

Technical Field

[0001] The invention relates to the technical field of steel welding, and in particular to a construction steel welding device. Background Art

[0002] Welding can connect various construction steel components into complex shapes, such as frame structures, truss structures, etc. If welding operations are performed at locations 2 meters or more above the ground, such as the frame of a high-rise building, the tower body of a tower crane, or the beam of a bridge, it is considered high-altitude work.

[0003] After the installation of the steel structure of the outdoor steel building is completed, the welding workers need to climb onto the steel structure to weld the joints of the building steel. Since this is an outdoor high-altitude operation, there will be the influence of natural wind compared to welding the steel structure in the factory. Natural wind will make the arc unstable and accelerate the cooling rate of the melted metal at the weld. Since there are a large number of joints on the steel structure, setting up a wind shield and moving it frequently will reduce the overall efficiency of the construction and affect the quality of welding. In addition, the width of the I-beam is relatively small. When the welding worker stands on the I-beam to weld the joint, he needs to use hand support to stabilize his body and use the other hand to weld. Since the body is difficult to stabilize, the hand will shake during welding, causing the welding gun to shake, resulting in uneven welding at the weld, which has a negative impact on the overall quality of the welded joint.

[0025] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: the folding rod 1 and the folding rod 2 are fitted together on one side close to the hinge 3, the nut 603 is threadedly connected to the bolt composed of the half bolt 3 604 and the half bolt 4 605, the two springs 1 408 are in a tightened state, the slider 1 403 is located on the side of the sliding groove 1 401 close to the hinge 3, the spring 1 408 is located on the side of the sliding groove 2 402 close to the hinge 3, the two telescopic plates 502 are stored in the storage groove 1 501, the two automatic light-dimming panels 504 are respectively at an angle of ninety degrees to the two telescopic panels 502, the two automatic light-dimming panels 504 are located in the two storage grooves 2 505, the spring 2 710 is extended, and the spherical pin 709 is inserted into one of the central positioning holes 706, so that the positioning block 704 is in a vertical state, the spring 3 805 is extended, and the stopper 802 extends to the outside of the storage groove 3 801.

[0026] The working status is: Quick start of construction steel welding equipment: After the nut 603 is unscrewed from the half bolt three 604 and the half bolt four 605, the folding rod one 1 and the folding rod two 2 lose their limit and can be aligned in the horizontal direction. In the process of the folding rod one 1 and the folding rod two 2 gradually aligning with the hinge 3 as the center, the two triangular blocks 804 respectively contact the corresponding fixing frames 803, and then the inclined surface of the triangular block 804 cooperates with the groove of the fixing frame 803 to press the fixing frame 803 downward, thereby driving the stopper 802 to be retracted into the storage groove three 801. When the folding rod one 1 and the folding rod two 2 are completely aligned, the nut 603 is screwed on the half bolt one 601 and the half bolt two 602 to fix the folding rod one 1 and the folding rod two 2, so as to achieve the effect of rapid deployment, so as to facilitate construction workers to carry welding equipment in a folded state to climb construction steel when not in use.

[0027] Install the construction steel welding equipment next to the welding area: After the construction steel welding equipment is unfolded and installed, the side of the construction steel welding equipment with the spring 1 408 is placed above the steel. Then the welding worker holds the construction steel welding equipment with one hand and pulls the clamping plate 407 at the bottom of the folding rod 1 in the direction away from the hinge 3 with the other hand, so that the clamping plate 407 drives the slider 1 403 to slide, thereby causing the slider 1 403 to pull the wire rope 404, and then under the action of the roller 2 405, the wire rope 404 pulls the slider 2 406, thereby driving the clamping plate 407 at the bottom of the folding rod 2 2 to slide in the direction away from the hinge 3. When the two clamping plates 407 slide to both sides, the two springs 1 408 are respectively subjected to sliding. After the clamp 407 at the bottom of the folding rod 1 is loosened, the slider 1 403 and the slider 2 406 will slide toward the hinge 3 under the action of the spring 1 408 and contact the two sides of the steel, so that the two clamps 407 are clamped on the steel under the elastic force of the spring 1 408, so as to achieve the effect of quickly installing and fixing the construction steel welding equipment, and the two windshields 411 fixedly connected to the slider 1 403 and the slider 2 406 through the connecting block 410 are moved to the positions on both sides of the steel, thereby providing a windshield effect for the welding point.

[0028] Use welding positioning components to improve welding accuracy: The gun head of the welding gun 9 drives the positioning block 704 to rotate. When the ball pins 709 on both sides of the positioning block 704 are subjected to external force, the ball pins 709 are squeezed by the positioning holes 706 and push the piston 708, so that the piston 708 slides into the sliding groove 5 707 and squeezes the spring 2 710. When the positioning block 704 continues to rotate to drive the ball pin 709 to align with the next positioning hole 706, the spring 2 710 stretches and pushes the piston 708, so that the ball pin 709 is stuck in the positioning hole 706 under the action of the piston 708. Continue to twist and repeat this process until the welding gun 9 is By aligning the gun tip with the welding position, the angle of the welding gun 9 can be adjusted according to the installation distance, thereby improving the welding accuracy of the welding gun 9. Subsequently, the positioning block 704 is pulled to one side of the sliding groove four 701, so that the fixing frame 703 drives the sliding block three 702 to slide inside the sliding groove four 701 through the fixing frame 703. After the sliding block three 702 reaches one side of the sliding groove four 701, welding begins and is gradually pushed to the other side, so that the welding gun 9 located inside the positioning block 704 can move horizontally under the limiting action of the sliding block three 702 and the sliding groove four 701, thereby further improving the welding accuracy.

[0029] Use protective components to provide light blocking effects: Since most of the welding and installation of construction steel is done at high altitude, the welder needs to climb with one hand to stabilize the body and use the other hand to do the welding work. It is not convenient to use a welding mask at this time, so the protective component on the construction steel welding equipment can be used. When in use, the automatic darkening sheet plate 504 is rotated out of the storage slot 2 505, and then the automatic darkening sheet plate 504 is pulled upward according to the viewing angle height, so that the automatic darkening sheet plate 504 drives the telescopic plate 502 to slide upward through the damping shaft 503. After the automatic darkening sheet plate 504 is pulled to a height with a better shading effect, the nylon damping allows the automatic darkening sheet plate 504 to be fixed at this height, thereby reducing the splashes generated during welding from splashing onto the welder's body, thereby protecting the welder during welding.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
