Detailed implementation manners

[0015] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, rather than limiting the utility model. In addition, it should be noted that, for the sake of convenience of description, only the parts related to the utility model are shown in the drawings.

[0016] The drawings in the embodiments of the present utility model: Different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the cross-sectional views of the components in the figure.

[0017] Please refer to Figures 1-3 , a steel structure butt welding adjustment device, including a support frame 1. The inside of the support frame 1 is rotatably connected with a first rotating shaft 2 and a second rotating shaft 3. The outer side of the top end of the first rotating shaft 2 is fixedly sleeved with a first support plate 4 located above the support frame 1. The outer side of the top end of the second rotating shaft 3 is fixedly sleeved with a second support plate 5 located above the support frame 1. A first placing plate 6 is placed on the surface of the first support plate 4. A second placing plate 7 is arranged on the surface of the second support plate 5. An angle adjusting mechanism 8 is fixedly installed on the inner side of the support frame 1. Lifting mechanisms 9 for fixedly connecting with the first placing plate 6 and the second placing plate 7 are arranged at the bottoms of the first support plate 4 and the second support plate 5. Clamping mechanisms 10 are arranged on one side of the tops of the first placing plate 6 and the second placing plate 7.

[0018] Among them, the angle adjustment mechanism 8 includes a mounting plate 81 arranged inside the support frame 1, a first gear 82 fixedly sleeved on the outer side of the bottom end of the first rotating shaft 2, and a second gear 83 fixedly sleeved on the outer side of the bottom end of the second rotating shaft 3. A hydraulic cylinder 84 is fixedly sleeved inside the mounting plate 81. By driving the hydraulic cylinder 84, the rack 85 can be pressed and limited while ensuring that the rack 85 does not move, so that the first support plate 4 and the second support plate 5 will not rotate on their own after the angle adjustment. The outer edges of the first gear 82 and the second gear 83 are jointly engaged with a rack 85 sleeved on the support frame 1 and located above the hydraulic cylinder 84. By the combined use of the first rotating shaft 2, the second rotating shaft 3, the first gear 82, the second gear 83 and the rack 85, when a person rotates the first support plate 4 or the second support plate 5, the first support plate 4 and the second support plate 5 can rotate in the opposite direction synchronously, so as to adjust the butt joint angle of the steel.

[0019] Among them, two symmetrically distributed limiting columns are fixedly sleeved inside the rack 85. The limiting columns can be used to limit the rack 85 to prevent the rack 85 from disengaging from the inner side of the support frame 1 during the rotation of the first support plate 4 and the second support plate 5.

[0020] Among them, the lifting mechanism 9 includes a U-shaped frame 91 arranged at the bottoms of the first support plate 4 and the second support plate 5, a first fixing rod 92 and a second fixing rod 93 movably sleeved inside the first support plate 4 and the second support plate 5. The tops of the first fixing rod 92 and the second fixing rod 93 are fixedly connected to the first placing plate 6 and the second placing plate 7, and a connecting plate 94 is fixedly sleeved on the outer sides of the bottoms of the first fixing rod 92 and the second fixing rod 93. A lead screw 95 rotatably connected inside the first support plate 4, the second support plate 5 and the U-shaped frame 91 is threadedly sleeved inside the connecting plate 94. A first turntable 96 is fixedly sleeved on the outer side of the bottom end of the lead screw 95 extending outside the U-shaped frame 91. By rotating the first turntable 96, the lead screw 95 can be rotated while driving the first placing plate 6 or the second placing plate 7 to lift, so as to compensate for the height difference between the plates and ensure that the welding points of the steel do not shift.

[0021] Among them, the clamping mechanism 10 includes a first fixing plate 101 and a second fixing plate 102 arranged on the tops of the first placing plate 6 and the second placing plate 7. A bidirectional lead screw 103 is sleeved between the first fixing plate 101 and the second fixing plate 102. The outer sides of both ends of the bidirectional lead screw 103 are respectively threadedly sleeved with a first limiting plate 104 and a second limiting plate 105 which are clamped inside the tops of the first supporting plate 4 and the second supporting plate 5. The inside of the top of the first fixing plate 101 is threadedly sleeved with a bolt 106 whose bottom end is clamped inside one end of the bidirectional lead screw 103. The bidirectional lead screw 103 can be positioned by the bolt 106 to prevent the bidirectional lead screw 103 from moving inside the first fixing plate 101 and the second fixing plate 102, ensuring that the bidirectional lead screw 103 can drive the first limiting plate 104 and the second limiting plate 105 to move during rotation. One end of the bidirectional lead screw 103 extending outside the second fixing plate 102 is fixedly sleeved with a second turntable 107. By rotating the second turntable 107, the bidirectional lead screw 103 can be rotated while driving the first limiting plate 104 and the second limiting plate 105 to move in the opposite direction along the axial direction of the bidirectional lead screw 103, thereby clamping and fixing the steel placed on the first placing plate 6 and the second placing plate 7.

[0022] When the device is in use, place the steel on the tops of the first placing plate 6 and the second placing plate 7. Rotate the bidirectional lead screw 103 through the second turntable 107 to clamp and fix the steel on the first placing plate 6 or the second placing plate 7. According to the position of the welding joint of the other steel, while pushing the first supporting plate 4 or the second supporting plate 5, drive the first placing plate 6 and the second placing plate 7 to rotate in the opposite direction synchronously through the cooperation of the first gear 82, the second gear 83 and the rack 85. When the welding joint position of the other steel is aligned with the welding joint position of the fixed steel, rotate the bidirectional lead screw 103 through the second turntable 107 to clamp and fix the steel on the first placing plate 6 or the second placing plate 7 that is not fixed, and start the hydraulic cylinder 84. Press and fix the rack 85 through the piston rod inside the hydraulic cylinder 84 to complete the adjustment of the docking angle of the steel. If the welding joints of the steel are uneven in height, rotate between the lead screws 95 through the first turntable 96, and at the same time drive the first placing plate 6 or the second placing plate 7 to move through the threaded transmission between the connecting plate 94 and the lead screws 95, thereby adjusting the height of the steel so that the welding joints of the steel can be aligned.
