Description

Technical Field

[0001] This utility model relates to the field of electroslag pressure welding technology, and in particular to a concentric positioning device for electroslag pressure welding. Background Technology

[0002] Electroslag pressure welding is mainly used for welding connections of vertical or inclined reinforcing bars in reinforced concrete structures, especially for connections of large-diameter reinforcing bars. However, during the electroslag pressure welding process, due to the special nature of the construction process, the ends of the reinforcing bars at the longitudinal quasi-connection part are affected by the whip effect, causing the welded joint to deviate longitudinally, resulting in frequent rework due to eccentricity and exceeding specifications.

[0003] Existing pressure welding methods are prone to misalignment during welding, which significantly affects the strength of the connection.

[0004] Therefore, a concentric positioning device for electroslag pressure welding is needed. Utility Model Content

[0005] The present invention proposes a concentric positioning device for electroslag pressure welding, which solves the problem in the prior art that the welding process is prone to displacement, which has a significant impact on the strength of the connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electroslag pressure welding concentric positioning device includes a bracket, a screw rod passing through the middle of the bracket, an adjusting frame passing through the outer side of the screw rod, a clamping mechanism being provided at the top of the adjusting frame, a steel bar body being clamped in the middle of the clamping mechanism, a connecting mechanism being welded to the rear side of the adjusting frame, and a hook being integrally provided at the end of the connecting mechanism.

[0008] Preferably, guide rods extend through the bottom of both sides of the adjustment frame, springs are installed on the outer sides of the guide rods, and a fixing frame is connected to the end of the springs.

[0009] Preferably, the adjusting frame forms a sliding structure between the screw and the guide rod, and the fixed frame is rotatably connected to the screw.

[0010] Preferably, the clamping mechanism includes a slot, a support is fixed to the side of the slot, a bolt is threaded to the top of the support, a rotating block is rotatably connected to the outside of the bolt, and a control rod is fixed to the top front end of the rotating block.

[0011] Preferably, the rotating block forms a rotating structure with the support via bolts, and the main body of the reinforcing bar forms an engaging structure with the slot via the rotating block.

[0012] Preferably, the connecting mechanism includes a connecting frame, and a rotating ring is provided inside the connecting frame, with an adjusting rod threadedly connected to the center of the rotating ring.

[0013] Preferably, the adjusting rod forms a translational structure with the connecting frame via a rotating ring, and the connecting frame and the rotating ring are rotatably connected.

[0014] This utility model proposes a concentric positioning device for electroslag pressure welding. Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a clamping mechanism, the clamping mechanisms at the top of the adjusting frame and the fixed frame are respectively engaged with the two sections of steel bars to be welded. The steel bars are inserted into the top of the slot, and the rotating block is rotated around the bolt to adjust the angle until the rotating block is perpendicular to the top of the slot to complete the clamping operation. The adjustment is flexible. If necessary, the bolt on the support can be turned out to adjust the distance between the rotating block and the slot, which better adapts to the clamping and limiting fixing operation of steel bars of different specifications and facilitates connection and positioning. After positioning, the adjusting frame can be stabilized by rotating the screw at the bottom of the control equipment to slide back and forth along the guide rod. This ensures that the steel bars at both ends can be accurately aligned and welded concentrically. The clamping can be further adjusted by the screw to ensure a tighter clamping operation. With the springs on both sides, the relative force further ensures the stability of the clamping. The concentric setting of the clamping mechanisms at both ends can better ensure the stability of the clamping, which is conducive to ensuring and improving the welding effect.

[0016] 2. By setting up a connecting mechanism, the connecting mechanism and hook on the side can hook with the side steel bars, so that the main welded bar can be supported and paralleled by the side steel bars, further ensuring the stability and accuracy of the overall welding. The extension of the adjustment rod can be adjusted according to different spacings. After the hook hooks the steel bar, rotating the ring can flexibly and quickly drive the adjustment rod to extend or retract through the internal thread. Flexible and quick adjustment is convenient to adapt to welding positioning under different conditions. Attached Figure Description

[0024] Furthermore, guide rods 4 extend through the bottom of both sides of the adjustment frame 3, and springs 5 ​​are installed on the outer side of the guide rods 4. A fixing frame 6 is connected to the end of the springs 5.

[0025] Furthermore, the adjusting frame 3 forms a sliding structure between the screw 2 and the guide rod 4, and the fixed frame 6 is rotatably connected to the screw 2. The screw 2 can be used to further adjust the clamping, ensuring a tighter clamping operation. In conjunction with the springs 5 ​​on both sides, the relative force further ensures the stability of the clamping.

[0026] Furthermore, the clamping mechanism 7 includes a slot 701, a support 702 fixed to the side of the slot 701, a bolt 703 threadedly connected to the top of the support 702, a rotating block 704 rotatably connected to the outside of the bolt 703, and a control rod 705 fixed to the top front end of the rotating block 704. The clamping mechanism 7 on the top of the adjusting frame 3 and the fixed frame 6 are respectively clamped and connected to the two welded steel bars. The steel bars are inserted into the top of the slot, and the rotating block 704 is rotated to adjust the angle around the bolt 703 until the rotating block 704 is perpendicular to the top of the slot 701 to complete the clamping operation. The adjustment is flexible. When necessary, the bolt 703 can be unscrewed from the support 702 to adjust the distance between the rotating block 704 and the slot 701, which better adapts to the clamping and limiting fixing operation of steel bars of different specifications and facilitates connection and positioning.

[0027] Furthermore, the rotating block 704 forms a rotating structure with the support 702 via the bolt 703, and the main body 8 of the reinforcing bar forms a locking structure with the slot 701 via the rotating block 704. This allows for flexible adjustment. When needed, the bolt 703 can be unscrewed from the support 702 to adjust the distance between the rotating block 704 and the slot 701, better adapting to the locking and limiting fixing operation of reinforcing bars of different specifications, and facilitating connection and positioning. Once positioning is completed...

[0028] Furthermore, the connecting mechanism 9 includes a connecting frame 901, inside which is a rotating ring 902, and the center of the rotating ring 902 is threadedly connected to an adjusting rod 903; the connecting mechanism 9 and the hook 10 on the side can hook with the side steel bars, so that the main welding bar can be supported and paralleled by the side steel bars, further ensuring the stability and accuracy of the overall welding, and the extension amount of the adjusting rod 903 can be adjusted according to different spacings.

[0029] Furthermore, the adjusting rod 903 forms a translation structure with the connecting frame 901 through the rotating ring 902, and the connecting frame 901 and the rotating ring 902 are rotatably connected; after the hook 10 hooks the steel bar, rotating the rotating ring 902 can flexibly and quickly drive the adjusting rod 903 to extend or retract through the internal thread, which can be flexibly and quickly adjusted to facilitate welding positioning under different conditions.

[0030] Working principle: First, the clamping mechanism 7 at the top of the adjusting frame 3 and the fixed frame 6 are respectively engaged with the two sections of steel bars to be welded. The steel bars are inserted into the top of the slot 701, and the rotating block 704 is rotated around the bolt 703 to adjust the angle until the rotating block 704 is perpendicular to the top of the slot 701 to complete the clamping operation. The adjustment is flexible. When necessary, the bolt 703 can be turned out from the support 702 to adjust the distance between the rotating block 704 and the slot 701, which better adapts to the clamping and limiting fixing operation of steel bars of different specifications and facilitates connection and positioning. After positioning, the adjusting frame 3 can be rotated and stabilized by controlling the screw 2 at the bottom of the equipment to slide back and forth along the guide rod 4. This ensures that the steel bars at both ends can be accurately aligned and welded concentrically. At the same time, the clamping can be further adjusted by the screw 2 to ensure a tighter clamping operation. With the springs 5 ​​on both sides, the relative force further ensures the stability of the clamping. While ensuring that the clamping mechanisms 7 at both ends are concentric, the clamping stability can be better guaranteed, which is conducive to ensuring and improving the welding effect.

[0031] Next, the connecting mechanism 9 and the hook 10 on the side can hook with the side steel bars, so that the main welded bar can be supported and paralleled by the side steel bars, further ensuring the stability and accuracy of the overall welding. The extension of the adjustment rod 903 can be adjusted according to different spacings. After the hook 10 hooks the steel bar, rotating the rotating ring 902 can flexibly and quickly drive the adjustment rod 903 to extend or retract through the internal thread. The flexible and quick adjustment is convenient to adapt to welding positioning under different conditions.
