[0038] Example:

[0039] like Figures 1 to 8 As shown, the utility model is a large H-beam welding turning machine, comprising a turning power frame unit 1 and a turning driven frame unit 2. A plurality of the turning power frame units 1 are evenly and equidistantly arranged along a straight line, and a turning driven frame unit 2 is arranged between two adjacent turning power frame units 1; both ends of the turning driven frame unit 2 are respectively connected to a turning power frame unit 1, and the turning driven frame unit 2 rotates synchronously with the turning power frame unit 1. In this embodiment, the large H-beam can be effectively mounted and fixed thereon by connecting a plurality of the turning power frame units 1 in series along a straight line, and at the same time, the turning effect of the turning power frame unit 1 is utilized to achieve a stable turning effect on the large H-beam, thereby avoiding the problem of poor welding effect of the H-beam due to unstable shape. At the same time, the turning driven frame unit 2 is arranged between the two turning power frame units 1 for series connection, which can ensure the smooth production of the H-beam entering the welding turning machine, and at the same time reduce the use of the turning power frame unit 1 to reduce the investment cost of the device.

[0040] In this embodiment, the preferred flip power frame unit 1 includes a flip table 11, a mounting bracket 12, a bottom bracket 13, and a hydraulically driven flip assembly 14. The flip table 11 is rotatably mounted on the top of the mounting bracket 12, and the mounting bracket 12 is vertically set at both ends of the bottom bracket 13.

In this embodiment, the bottom bracket 13 is used to achieve the effect of stably installing the entire device on the ground, and then the mounting bracket 12 vertically set thereon provides an installation location for the flip table 11, while ensuring the height requirement of the H-beam from the ground to avoid the H-beam contacting the ground during reversal. In this embodiment, the hydraulically driven flip assembly 14 is preferably used to drive the flip table 11, thereby achieving the flipping effect of the H-beam. Furthermore, a flip shaft 15 is provided at both ends of the flip table 11, and a bearing seat 16 is provided at the top of the mounting bracket 12, and the flip shaft 15 cooperates with the bearing seat 16; a driven shaft 21 is provided at both ends of the flip driven frame unit 2, and the driven shaft 21 also cooperates with the bearing seat 16, and the driven shaft 21 rotates synchronously with the flip shaft 15.

[0041] In this embodiment, in order to achieve the fixation and anti-overturning effect of the H-beam, the flip power frame unit 1 also includes an H-beam anti-overturning assembly 17. Multiple H-beam anti-overturning assemblies 17 are movably arranged at both ends of the flip platform 11, and the H-beam anti-overturning assemblies 17 are clamped to the side of the H-beam. Specifically, the H-beam anti-overturning assembly 17 includes a clamp 171, a screw 172, an anti-tilt bar 173, and a bar driver 174. The clamp 171 is threadedly sleeved on the screw 172, and the clamp 171 moves along the axial direction of the screw 172; the fixed end of the bar driver 174 is fixed to the clamp 171, and the movable end of the bar driver 174 extends vertically upward and is fixed to the anti-tilt bar 173. The anti-tilt bar 173 slides up and down in the through hole opened on the clamp 171. During operation, after the H-shaped steel is installed in place, the screw rod 172 is first used to drive the reinforcement 171 toward the two sides of the H-shaped steel, and then the inclined baffle 173 is driven upward by the baffle driving member 174, so that the inclined baffle 173 is surrounded on the side of the H-shaped steel, thereby effectively avoiding the problem of overturning of the H-shaped steel when it is turned over.

[0042] In this embodiment, in order to effectively achieve the driving effect of the H-shaped steel anti-overturning assembly 17, the flipping power frame unit 1 also includes a screw drive assembly 18, and the screw drive assembly 18 is provided on both sides of the flipping platform 11; specifically, the screw drive assembly 18 includes a synchronous motor 181, an intermediate transmission member 182, a first commutator 183 and a second commutator 184, the output end of the synchronous motor 181 is connected to the input end of the first commutator 183, the commutation end of the first commutator 183 is connected to the screw 172 on one side of the flipping platform 11, the same direction end of the first commutator 183 is connected to one end of the intermediate transmission member 182, the other end of the intermediate transmission member 182 is connected to the input end of the second commutator 184, and the commutation end of the second commutator 184 is connected to the screw 172 on the other side of the flipping platform 11.

Similarly, the flip driven frame unit 2 is also equipped with the H-beam conveying assembly 19.

[0044] The welding tilting machine also includes a single-sided cantilever unit 3, with one single-sided cantilever unit 3 provided at each end of the welding tilting machine. In this embodiment, the single-sided cantilever unit 3 effectively supports the H-beam at both ends of the device and also reserves space for the cantilever welding machine's welding head to stop.

[0045] The turning table 11 has a rotation range of -45° to +45°. When the drive shaft of the hydraulically driven turning assembly 14 is retracted into position, the turning table 11 rotates to -45°. When the drive shaft of the hydraulically driven turning assembly 14 is extended into position, the turning table 11 rotates to +45°. In this embodiment, the hydraulically driven turning assembly 14 can drive the turning table 11 to turn within a range of -45° to +45°. When the welding turning machine turns the H-beam to -45° or +45, the welding gun can be pointed vertically downward to perform ship-shaped welding. When the H-beam is placed horizontally, that is, when the welding turning machine is at 0°, bilateral right-angle welding can be performed.
