After matching, the two cylindrical sleeves are respectively connected to the spherical frame to form a connecting area that penetrates the spherical frame. The utility model completes the welds of the upper and lower steel columns by forming a connecting area that penetrates the spherical frame. The utility model realizes the fixed welding of steel columns in construction projects, and can meet the welding needs of steel columns with various cross-sectional shapes, greatly improving work efficiency.

[0004] However, the above welding device still has some shortcomings in actual use: there is only a cylindrical sleeve standing on the ground at the lower end of the device. Due to its long length and the lack of other supports, the stability of the device is poor, which in turn affects the welding effect. Utility Model Content

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Reference Figure 1-Figure 3 As shown, a device suitable for fixing and welding steel columns comprises two cylindrical sleeves 1 and two hemispherical sleeves 2. The two hemispherical sleeves 2 are combined into a spherical frame. The two hemispherical sleeves 2 are assembled and fixed by bolts. A reserved hole 15 is provided on the surface of the spherical frame, which mainly plays the role of heat dissipation and air circulation inside the device. The two cylindrical sleeves 1 are respectively connected to the hemispherical bottoms of the two hemispherical sleeves 2. A steel column 3 is axially sleeved in the cylindrical sleeve 1. The steel column 3 is square, round or regular polygonal. A movable block 4 is slidably sleeved on the upper part of the cylindrical sleeve 1 located below the spherical frame. The movable block 4 is square and has four sides fixedly connected to a rotating shaft. A support plate 5 is rotatably connected to the surface of the rotating shaft. Baffles 6 are fixedly connected to the four sides of the movable block 4. The baffles 6 are at an angle of 30° to the side of the movable block 4 and are located outside the support plate 5 to limit the expansion range of the support plate 5. The maximum angle at which the support plate 5 can rotate around the rotating shaft is 30°. A control device is installed on the movable block 4, which is started or closed by remote control to expand the support plate 5. open or closed; by arranging a support plate 5 on the cylindrical sleeve below the device, and unfolding the support plate 5 through the control device when in use, the stability of the device can be improved and the welding effect can be guaranteed; a cylindrical channel 7 and a cylindrical frame 8 are opened inside the hemispherical sleeve 2, and a clamping rod 9 is fixedly connected between the cylindrical channel 7 and the cylindrical frame 8. There are four clamping rods 9 and they are evenly distributed between the cylindrical channel 7 and the cylindrical frame 8. Two embedded devices 10 are movably connected in the cylindrical frame 8. The two embedded devices 10 According to the upper and lower structural arrangement, the embedded device 10 is a retractable three-dimensional structure with one end large and the other end small, and its width decreases evenly from the large end to the small end. At the same time, contact sensing devices are installed above and below the small end. The small end can be rotated clockwise or counterclockwise around the contact surface by controlling the button. A track 11 is opened between the two embedded devices 10, and a welding head 12 is movably connected to the track 11. The welding head 12 is fixedly connected to a straight rod 13, and the straight rod 13 is fixedly connected to an electric welding machine 14.
