[0002] H-beam is an economical cross-section profile with a cross-section shape similar to the capital Latin letter H. It is also called universal steel beam, wide flange (edge) I-beam or parallel flange I-beam. The cross-section of H-beam usually consists of two parts: web and flange, also known as waist and edge.
[0003] H-shaped steel is commonly used in various civil and industrial building structures, various large-span industrial plants and modern high-rise buildings. When in use, H-shaped steel is generally large in mass and volume. Usually, H-shaped welding is carried out by arc welding, gas shielded welding, etc., which needs to be carried out in a relatively open and flat area. When welding, workers need to hold the welding head and span a large area. When the workers move, the connected pipelines will be entangled and scattered with each other, and will be pulled by the steel placed on the ground, and need to be constantly sorted out. In addition, the welding working range is limited by the length of the connecting pipelines, and the welding equipment and auxiliary welding gas cylinders need to be constantly moved, and the welding work cannot be carried out smoothly.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] Example 1: An H-shaped steel welding device, such as Figure 1-3 As shown, it includes a welding platform 1, a track 2, a frame 3, a guide rail 4, a welding device 5, a fixing frame 51, an integrated hose 6, a welding head 7, a support plate 8 and a wire take-up device 9. The welding platform 1 is made of high-strength metal material, and its upper side is a flat table top with a large area. The welding platform 1 is used for horizontal placement of H-shaped steel during welding. The left and right sides of the welding platform 1 are fixedly connected to the track 2. A frame 3 is slidingly provided between the track 2. The friction between the frame 3 and the track 2 is small. The frame 3 can move smoothly back and forth on the track 2. The upper part of the frame 3 is fixedly connected to the guide rail 4. The guide rail 4 is slidingly provided with a welding device 5 for steel welding. The upper part of the welding device 5 is connected to an integrated hose 6. The integrated hose 6 wraps all the pipelines of the welding device 5 together. The lower front side of the welding device 5 is fixedly connected to the fixing frame 51. The fixing frame 51 has a strip-shaped slot hole, and a round rotating rod is provided at the front. The left part of the fixing frame 51 is fixedly connected to a support plate 8; a wire take-up device 9 is provided on the upper part of the support plate 8, which consists of a shell, a winding rod rotating in the shell, a spring connected to the winding rod, and a cable wound on the winding rod. When the cable of the wire take-up device 9 is pulled out, the winding rod will rotate, the spring rotates to tighten and store force, and after the cable is released, the winding rod rotates under the action of the spring in the wire take-up device 9 to retract the cable. One end of the cable in the wire take-up device 9 is connected to the integrated hose 6, which is used to suspend the integrated hose 6 so that the lower end of the integrated hose 6 is always in a suspended state detached from the ground; the integrated hose 6 passes through the front of the fixing frame 51 and contacts the circular rotating rod in the fixing frame 51. The circular rotating rod in the fixing frame 51 limits the extension distance of the integrated hose 6 in the welding equipment 5, and at the same time reduces the friction during pulling, which is convenient for pulling. The lower part of the integrated hose 6 is connected to a welding head 7 for welding steel materials.
[0018] It should be noted that the length of the integrated hose 6 is set according to the needs of use. When the welding head 7 is pulled downward, it can contact the welding platform 1. The integrated hose 6 is pulled by the welding head 7 to pull out a section of the cable in the wire take-up device 9. The integrated hose 6 is always suspended by the cable of the wire take-up device 9. When the pulled welding head 7 is released, the wire take-up device 9 will automatically retract the cable, driving the integrated hose 6 and the welding head 7 to move upward; when welding work is required, multiple H-shaped steels that need to be welded are moved to the welding platform 1. After splicing, people move the frame 3 forward and backward to the appropriate position, and move the welding equipment 5 left and right to the area required for welding. The welding head 7 can be accurately moved to the welding point position after being pulled, and welding work is performed through the welding equipment 5 and the welding head 7. By setting the welding equipment 5 on the top of the movable gantry-shaped frame 3, the welding pipelines are uniformly arranged through the integrated hose 6, and the integrated hose 6 is suspended by the wire take-up device 9, so that the welding equipment and pipelines are separated from the ground and are not interfered with by ground objects. When in use, the position of the frame 3 is moved forward and backward and the position of the welding equipment 5 is moved left and right, and the coverage range of the welding area is flexibly changed, so that the welding head 7 can be moved and used at various positions of the welding platform 1 without dead angles, thereby ensuring that the welding work can be carried out smoothly.
[0019] Example 2: Based on Example 1, in order to ensure that the welded H-shaped steel can quickly adjust its position and direction during construction, Figure 1 and Figure 3As shown, it also includes a mounting frame 10, a bracket 11, a motor 12, a reel 13, a steel cable 14, a sling 141 and a claw 142. The front side of the upper part of the frame 3 is fixedly provided with a mounting frame 10 made of metal material, which can play a role of stable support. The front of the mounting frame 10 is fixedly connected to the bracket 11. The motor 12 that provides rotation force is installed on the left side of the bracket 11. The frame 3 should be equipped with a control switch that controls the forward and reverse rotation of the motor 12. A reel 13 is rotatably provided on the right side of the upper part of the bracket 11. The output shaft of the motor 12 passes through the upper part of the bracket 11 and is fixedly connected to the reel 13. The motor 12 drives the reel 13 to rotate and controls the reel 13 to take up and release the line. A steel cable 14 that can withstand a large radial tension is neatly wound inside the reel 13. The steel cable 14 passes around the outside of the pulley 111 and is in sliding contact with the pulley 111. The steel cable 14 plays a guiding and auxiliary role in retracting and releasing the reel 13. The lower part of the wire harness of the sling 141 is fixedly connected with a clamping claw 142, and the internal thread of the clamping claw 142 is provided with a screw that can clamp the steel and the clamping claw 142. When the steel on the welding platform needs to be moved or adjusted, the multiple clamping claws 142 on the sling 141 are clamped to different positions of the steel, and the steel cable is wound by the take-up wheel. The steel is lifted and people adjust the position of the lifted steel. It should be noted that the position of the multiple clamping claws 142 clamping the steel can ensure that the steel is in a relatively balanced state when the steel cable 14 and the sling 141 lift the steel, with a small inclination. The position and orientation of the welded H-shaped steel are transferred and adjusted by the provided lifting mechanism, without the need for manual handling by workers, thereby reducing the workload of workers and the risk of injury during human handling.
[0020] In a preferred embodiment: Figure 1-3 As shown, a wedge block 15 is also included. The front part of the welding platform 1 is fixedly connected to the wedge block 15. The wedge block 15 is in the shape of a long strip with a low front and a high back. The purpose of the sloped setting of the wedge block 15 is to facilitate pushing the steel into or out of the welding platform 1 from the front side. The use of the slope has a certain labor-saving effect, which can reduce the required pushing or pulling force during transportation.
[0021] In a preferred embodiment: Figure 1-2 As shown, a mounting base 16 is also included. The left and right sides of the frame 3 are fixedly connected with mounting bases 16 for equipment installation. The mounting base 16 is used to set a mounting platform, which can be used to install auxiliary welding equipment, such as a heating device for preheating the weldment before welding to reduce the probability of cracks, or a compressor for blowing out welding chip cleaning gas, etc., to assist in the welding work.
[0022] In a preferred embodiment: Figure 1-3As shown, a plurality of chip grooves 17 are evenly spaced on the surface of the welding platform 1. The chip grooves 17 facilitate timely discharge and cleaning of welding chips in the welding platform 1. Before welding, welding chips can be blown into the chip grooves 17 to avoid accumulation of welding chips on the welding platform 1, causing the H-shaped steel to be placed on an uneven surface, thereby reducing welding efficiency and quality.
[0023] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
