[0024] See also Figure 1-5 , the utility model provides an embodiment: a rotary building steel structure multi-angle welding device, including a support plate 3;

[0025] The outer sleeve of the bottom end of the support plate 3 is provided with a base 1, and a rotating disk 2 is installed at the bottom end of the support plate 3, and the rotating disk 2 is located inside the base 1 and is rotatably connected to the inner wall of the base 1, and locking mechanisms 4 are evenly arranged on both sides of the top of the rotating disk 2, and horizontal plates 13 are installed on both sides of the support plate 3, and guide blocks 14 are installed on the outer sides of the bottom ends of the horizontal plates 13, and a guide groove 15 is opened at the top end of the base 1, and the bottom ends of the guide blocks 14 extend to the inside of the guide groove 15;

[0027] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, when in use, the elastic action of the second spring 401 is used to make the clamping block 402 always press the top of the rotating disk 2, and the friction between the clamping groove 403 and the clamping block 402 is used to resist the inertial rotation of the support plate 3, so as to ensure the stability of the support plate 3 after rotation;

[0028] The outer parts of the rotating shafts 11 on both sides of the support plate 3 are sleeved with fixing sleeves 16, and the inner parts of the fixing sleeves 16 are uniformly provided with limiting grooves 18, and the outer parts of the rotating shafts 11 are uniformly embedded with balls 17, and one side of the balls 17 abuts against the limiting grooves 18, and the inner parts of the fixing sleeves 16 are made of flexible material;

[0029] Specifically, Figure 2 and Figure 3 As shown, when in use, the friction between the ball 17, the limiting groove 18 and the fixing sleeve 16 is used to improve the stability of the rotating shaft 11 after rotation, prevent the rotating shaft 11 from rotating randomly, and improve the stability of the steel structure welding;

[0030] A connecting shaft 8 passes through the top of the support plate 3, and both ends of the connecting shaft 8 are connected to a U-shaped frame 5, a U-shaped plate 9 is installed on the top of the U-shaped frame 5, and clamping mechanisms 10 are provided on both sides of the inside of the U-shaped plate 9;

[0031] The clamping mechanism 10 includes a limiting rod 1001 that passes through one side of the U-shaped plate 9, and a clamping plate 1003 is installed at one end of the limiting rod 1001. A first spring 1002 is sleeved on the outer portion of the limiting rod 1001 on one side of the clamping plate 1003, and the first spring 1002 is in a compressed state. Anti-slip bumps 1004 are evenly installed on the other side of the clamping plate 1003.

[0032] The top view cross section of the clamping plate 1003 is U-shaped, and the two sides of the U-shape are outwardly expanded, and the anti-slip bumps 1004 are distributed in an array with equal spacing on the clamping plate 1003;

[0033] Through holes 6 are provided at the bottom ends of both sides of the U-shaped plate 9, a rotating shaft 11 is passed through the interior of the support plate 3 below the connecting shaft 8, and connecting plates 12 are installed at both ends of the rotating shaft 11, a connecting rod 20 is installed at the bottom end of one side of the connecting plate 12, and one end of the connecting rod 20 passes through the interior of the through hole 6, and a handle 7 is installed at the end of the connecting rod 20 away from the connecting plate 12, and a roller 19 is sleeved on the part of the connecting rod 20 located in the through hole 6, and the outer diameter of the roller 19 is adapted to the width of the through hole 6, and the moving radius of the roller 19 is equal to half the length of the through hole 6;

[0034] Specifically, Figure 1 As shown, when in use, the special structure of the clamping plate 1003 is used to increase the contact area with the steel structure and improve the reliability of the clamping. The connecting rod 20 is rotated in a circle to make the roller 19 drive the bottom end of the U-shaped frame 5 to swing, so as to adjust the angle of the welding surface of the steel structure.

[0035] Working principle: When the utility model is used, first push the two clamping plates 1003 outwards, place the steel structure between the U-shaped plates 9, and under the elastic resetting and squeezing of the first spring 1002, the clamping plates 1003 move inwards, and drive the anti-slip protrusions 1004 to squeeze the steel structure, so as to fix the steel structure;

[0036] Secondly, the horizontal plate 13 is pushed to make the guide block 14 slide along the guide groove 15, and the support plate 3 drives the rotating disk 2 to rotate, so as to facilitate the rotation and adjustment of the welding surface of the steel structure. At the same time, during the rotation process, the clamping groove 403 moves synchronously. Because the clamping block 402 is always against the top of the rotating disk 2 under the elastic action of the second spring 401, and as the rotation of the rotating disk 2 stops, the clamping block 402 is correspondingly inserted into the inside of the clamping groove 403, so as to lock the rotating disk 2, so as to prevent the rotating disk 2 from rotating due to inertia, and improve the position stability of the support plate 3;

[0037] Finally, by turning the handle 7, the connecting rod 20 is pulled to drive the connecting plate 12 to rotate in a circle. Since the roller 19 is always located inside the through hole 6, the connecting rod 20 drives the roller 19 to move, and the roller 19 drives the bottom end of the U-shaped frame 5 to swing, so that the top end of the U-shaped frame 5 swings in the opposite direction, so as to further adjust the inclination angle of the welding surface of the steel structure, so that the equipment can meet different welding needs and improve its flexibility of use.
