Description

Technical Field

[0001] The utility model relates to the technical field of steel trusses, in particular to a steel truss narrow seam welding device. Background Art

[0002] Steel trusses are made of steel, and are characterized by using chords instead of flanges and webs instead of webs, with webs and chords connected to each other at each node through node plates or other parts with welds or other connections. This structure makes the bending moment of the steel truss mainly manifest as axial compression and tension of the upper and lower chords, and the shear force manifests as axial compression or tension of each web when it is bent. It is widely used in many fields such as industrial and civil buildings, bridges, towers, etc.

[0003] Steel truss welding refers to the process of welding steel into a truss structure. The steel truss is a structure composed of multiple rods connected by nodes. In order to ensure a firm connection between these rods and nodes, they generally need to be welded. Welding can form a strong cross connection at the connection point, eliminate the unevenness and roughness caused by the surface material and the floor slab, and ensure the integrity and rigidity of the structure when subjected to external loads. Generally, the overall structure of the steel truss is large. When the narrow seam of the steel truss needs to be welded, the welding position is too high, which requires the operator to climb up to weld the narrow seam of the steel truss.

[0004] However, the operator has to climb up to perform welding operation on the narrow seam position of the steel truss. During the welding process, the operator needs to consider standing firmly while performing the welding work. The safety performance is insufficient and it is easy to affect the welding effect of the narrow seam position of the steel truss. Therefore, it is necessary to propose a steel truss narrow seam welding device. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A steel truss narrow seam welding device comprises a first steel truss and a second steel truss, wherein the surface of the other side of the first steel truss is fitted with the surface of one side of the second steel truss; a box is provided on the top of the first steel truss, a controller is fixedly installed inside the box, a top cover is fixedly connected to the top of the box, a double-headed motor is fixedly installed on the bottom of the box, first pulleys are fixedly installed on the bottom of the box on both sides of the double-headed motor, a driving wheel is rotatably installed inside each first pulley, output shafts on both sides of the double-headed motor are respectively fixedly connected to the inner side of each driving wheel, a plurality of third pulleys are fixedly installed on the bottom of the box at both ends of each first pulley, a fixed block is fixedly connected to one end of the box, a welding head is fixedly installed on the other side of the fixed block, the welding head is located directly above between the first steel truss and the second steel truss, and limiting components for adjusting and limiting the position of the welding head are provided on both sides of the box.

[0008] After the first steel truss and the second steel truss are butt-jointed, the box is placed on top of the first steel truss and the second steel truss, and the two limit plates are moved to positions outside the first steel truss and the second steel truss respectively. According to the different specific widths of the first steel truss and the second steel truss, the limit components can be adjusted to drive the welding head to move to the position of the top of the first steel truss and the second steel truss, so as to facilitate the movement and adjustment of the welding head to the narrow seam position where the first steel truss and the second steel truss need to be welded, so as to facilitate the subsequent use of the welding head to perform welding operations on the narrow seam of the first steel truss and the second steel truss. By installing a double-headed motor, the two driving wheels can be driven to rotate at the same time, thereby automatically driving the welding head to move, so as to automatically perform welding operations on the narrow seam of the first steel truss and the second steel truss, thereby eliminating the need for operators to climb up to weld the narrow seam of the first steel truss and the second steel truss, thereby improving the safety performance of the device.

[0009] A further improvement of the technical solution of the utility model is that a camera is arranged on one side of the fixed block, and an adjusting component for adjusting the angle of the camera is arranged on the top of the camera.

[0010] The above technical solution is adopted. In this solution, a camera is installed to capture the welding condition of the welding head on the narrow gap between the first steel truss and the second steel truss. A controller is set to transmit the image captured by the camera to a remote receiving device, thereby facilitating the operator to remotely observe the welding condition of the welding head and improving the welding effect of the narrow gap between the first steel truss and the second steel truss.

[0014] The above technical solution is adopted. In this solution, the camera and the welding head can be separated by installing a protective cover, so as to prevent the waste chips generated during the narrow seam welding of the first steel truss and the second steel truss by the welding head from splashing onto the surface of the camera, thereby protecting the camera. In addition, by using transparent glass material for the protective cover, it can avoid affecting the picture taken by the camera of the narrow seam welding of the first steel truss and the second steel truss.

[0018] The above-mentioned technical solution is adopted. In this solution, by installing the second pulley, the two limit plates can be separated from the outer surfaces of the first steel truss and the second steel truss respectively. During the rolling of the active wheel, the two second pulleys can be driven to roll along the outer surfaces of the first steel truss and the second steel truss respectively, thereby guiding and limiting the moving trajectory of the welding head, ensuring that the welding head can accurately weld the narrow gaps of the first steel truss and the second steel truss.

[0019] A further improvement of the technical solution of the utility model is that a plurality of limit rods are fixedly installed on both sides of the box body outside each electric push rod, each limit rod on one side of the box body penetrates the inside of the limit plate on one side of the first steel truss, and each limit rod on the other side of the box body penetrates the inside of the limit plate on the other side of the second steel truss.

[0020] The above technical solution is adopted. In this solution, by installing a plurality of limit rods, the trajectories of the two limit plates driven by the two electric push rods can be guided and limited, thereby avoiding the limit plates from shifting, thereby improving the accuracy of the position adjustment of the welding joint.
