Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to a steel bar welding device for building construction. Background Technology

[0002] The steel reinforcement frame is an indispensable and important component in the concrete pouring process. In concrete structures, it is mainly used to compensate for the insufficient tensile strength of concrete. Through tensile bearing capacity and coordinated deformation, it can effectively improve the overall strength, durability and load-bearing capacity of concrete structures.

[0003] The steel reinforcement frame is connected by binding or lap splicing. However, in some cases, the structural strength of the steel reinforcement frame by binding or lap splicing is insufficient and cannot meet the requirements of the concrete structure. Welding is then used to connect the steel reinforcement frame. However, because the cross-section of the steel bars is circular and the outer surface has texture, there is a large gap when two sets of steel bars are joined together. During the welding operation, the molten droplets formed by the melting of the weld core can easily pass through the gap and flow out from the back, resulting in poor weld filling density and integrity. This greatly affects the connection strength of the steel bars. Furthermore, when welding the steel reinforcement frame, two welding operations are required on both sides of the joined steel bars, resulting in low efficiency, poor stability and reliability of the steel reinforcement frame welding.

[0004] Therefore, there is an urgent need for a steel bar welding device for building construction to solve the defects of the existing steel bar frame during welding operations. Summary of the Invention

[0005] This application proposes a steel bar welding device for building construction, which has the advantages of effectively improving the connection strength of the welded steel bar frame and having high welding efficiency for steel bar frames. It solves the problem that because the cross-section of the steel bar is circular and the outer surface is textured, there is a large gap when two sets of steel bars are joined together. During the welding operation, the molten droplets formed by the melting of the weld core can easily pass through the gap and flow out from the back side, resulting in poor weld filling density and integrity, which greatly affects the connection strength of the welded steel bars. In addition, when welding steel bar frames, two welding operations are required on both sides of the joined steel bars, resulting in low welding efficiency for steel bar frames.

[0006] To achieve the above objectives, this application adopts the following technical solution: a steel bar welding device for building construction, comprising an outer sleeve with a beveled bottom, two sets of retaining rings fixedly installed in the middle of the outer surface of the outer sleeve, and a connecting block movably engaged between the two sets of retaining rings by bolts, thereby adjusting the rotation angle of the connecting block relative to the outer sleeve by bolts; a linear slide rail fixedly installed on the connecting block, and a drive motor slidably connected to the linear slide rail, thereby moving along the trajectory of the linear slide rail under the drive of the drive motor; a herringbone-shaped bracket fixedly sleeved on the outer surface of the drive motor, and a set of welding gun heads for welding steel bars are respectively provided at both ends of the bracket; a locking mechanism is provided on the left side of the outer surface of the outer sleeve. The structure is fixed to the first reinforcing bar by a locking mechanism. The relative position of the outer sleeve and its structure on the first reinforcing bar can be adjusted by the locking mechanism. When welding the reinforcing bar, the welding gun head on the drive motor is located at the initial point of the weld after the first and second reinforcing bars are merged. Under the action of the drive motor, the welding gun head moves to the right along the trajectory of the linear slide rail, so as to simultaneously perform welding operations on the two sides of the first and second reinforcing bars that overlap, which makes the welding efficiency of the reinforcing bars high. At the same time, by using the molten welding core to apply pressure to each other on the opposite side, it can effectively prevent the back side of the gap formed by the first and second reinforcing bars from flowing out, and make the weld filling density and integrity high.

[0007] Furthermore, the width of the bevel at the bottom of the outer sleeve is greater than the outer diameter of the first reinforcing bar, thereby ensuring that the outer sleeve can be inserted into the outer surface of the first reinforcing bar and locked using a locking mechanism.

[0008] Furthermore, the locking mechanism includes an inner clamping block movably connected to one side of the outer surface of the outer sleeve. A rotating collar is movably sleeved on one side of the outer surface of the outer sleeve, and a pressure spring is provided on the inner wall of the rotating collar. When it is necessary to clamp the outer sleeve onto the first reinforcing bar, the rotating collar can be rotated so that the pressure spring and the end of the inner clamping block cooperate with each other, and the elastic force of the pressure spring is used to press the inner clamping block inward, thereby stably clamping the outer sleeve onto the outer surface of the first reinforcing bar.

[0009] Furthermore, one side of the rotating collar has a cut structure with the same width as the bevel on the outer sleeve, and initially, the cut on the rotating collar and the bevel on the outer sleeve coincide to facilitate the outer sleeve being snapped onto the first reinforcing bar.

[0010] Furthermore, the bottom of the inner clamping block is designed with a V-shaped structure to facilitate the application of pressure to the first reinforcing bar, ensuring a stable connection between the outer sleeve and the first reinforcing bar, and effectively adapting to reinforcing bar structures of different specifications and sizes.

[0011] Furthermore, the outer surface of the pressure spring is designed with an arc-shaped structure, and an arc-shaped groove is provided at the end of the inner clamping block to match it. Then, after the rotating collar drives the pressure spring to rotate to a certain angle, the pressure spring can engage with the arc-shaped groove at the end of the inner clamping block. By utilizing the corresponding degree of elastic deformation of the pressure spring, the amount of inward movement of the inner clamping block can be controlled based on the specifications and dimensions of the steel reinforcement structure, which effectively improves the adaptability of the steel reinforcement welding device.

[0012] Furthermore, the welding gun head is fixedly connected to the bracket by bolts, and the deflection angle of the welding gun head is adjusted according to the size of the first reinforcing bar so that the intersection of the central axes of the two sets of welding gun heads is located on the tangent between the first reinforcing bar and the second reinforcing bar.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The steel bar welding device for building construction provided in this application, with the setting of the connecting block and its structure, allows for simultaneous welding of the overlapping sides of the first and second steel bars using two sets of welding guns during steel bar welding operations, resulting in high efficiency in steel bar welding. At the same time, by using the molten welding core to apply pressure to each other on opposite sides, it can effectively prevent the back side of the gap formed by the molten welding core and the first and second steel bars from flowing out, resulting in better density and integrity of the weld filling, and higher connection strength of the steel bar weld.

[0015] 2. The steel bar welding device for building construction provided in this application, in terms of the setting of the locking mechanism and its upper structure, can apply inward pressure to the inner clamping block by rotating the rotating collar and using the pressure spring on it, thereby clamping the outer sleeve onto the steel bar structure. The elastic deformation of the pressure spring is used to control the inward movement of the inner clamping block based on the specifications and dimensions of the steel bar structure, which effectively improves the adaptability of the steel bar welding device and has high stability and reliability.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 , Figure 2 As shown, a steel bar welding device for construction engineering includes an outer sleeve 1 with a bevel at the bottom. Two sets of retaining rings 2 are fixedly installed in the middle of the outer surface of the outer sleeve 1, and a connecting block 3 is movably connected between the two sets of retaining rings 2 by bolts. The rotation angle of the connecting block 3 relative to the outer sleeve 1 can be adjusted by bolts. A linear slide rail 4 is fixedly installed on the connecting block 3, and a drive motor 5 is slidably connected to the linear slide rail 4. Under the driving action of the drive motor 5, it can move along the trajectory of the linear slide rail 4. A bracket 6 with a herringbone structure is fixedly sleeved on the outer surface of the drive motor 5, and a set of welding gun heads 7 for welding steel bars is provided at both ends of the bracket 6. A locking mechanism 8 is provided on the left side of the outer surface of the outer sleeve 1, and the outer sleeve 1 and its structure are fixedly installed on the first steel bar 9 by the locking mechanism 8. The relative position of the outer sleeve 1 and its structure on the first steel bar 9 can be adjusted by the locking mechanism 8.

[0024] Furthermore, during the welding operation of the reinforcing bars, the drive motor 5 and the welding gun head 7 on it are located at the initial point of the weld after the first reinforcing bar 9 and the second reinforcing bar 10 are merged. Under the action of the drive motor 5, the welding gun head 7 is driven to move to the right along the trajectory of the linear slide rail 4, so as to simultaneously perform welding operations on the two sides of the first reinforcing bar 9 and the second reinforcing bar 10 that overlap, thus making the welding efficiency of the reinforcing bars higher. At the same time, by using the molten welding core to apply pressure to each other on the opposite side, it can effectively prevent the back side of the gap formed by the molten welding core of the first reinforcing bar 9 and the second reinforcing bar 10 from flowing out, and make the weld filling density and integrity higher.

[0025] like Figure 2As shown, in this technical solution, the width of the bottom bevel of the outer sleeve 1 is greater than the outer diameter of the first reinforcing bar 9, thereby ensuring that the outer sleeve 1 can be inserted into the outer surface of the first reinforcing bar 9 and locked by the locking mechanism 8.

[0026] like Figure 3 , Figure 4 As shown, in this technical solution, the locking mechanism 8 includes an inner clamping block 11 movably connected to one side of the outer surface of the outer sleeve 1. A rotating collar 12 is movably sleeved on one side of the outer surface of the outer sleeve 1, and a pressure spring 13 is provided on the inner wall of the rotating collar 12. When it is necessary to clamp the outer sleeve 1 onto the first reinforcing bar 9, the rotating collar 12 can be rotated so that the pressure spring 13 and the end of the inner clamping block 11 cooperate with each other, and the elastic force of the pressure spring 13 is used to press the inner clamping block 11 inward, thereby stably clamping the outer sleeve 1 onto the outer surface of the first reinforcing bar 9.

[0027] like Figure 1 , Figure 4 As shown, in this technical solution, a cut structure with the same width as the bevel on the outer sleeve 1 is provided on one side of the rotating collar 12. Initially, the cut on the rotating collar 12 and the bevel on the outer sleeve 1 coincide with each other to facilitate the outer sleeve 1 being snapped onto the first reinforcing bar 9.

[0028] like Figure 1 , Figure 4 As shown, in this technical solution, the bottom of the inner clamping block 11 is designed with a V-shaped structure to facilitate the application of pressure to the first reinforcing bar 9, ensuring a stable connection between the outer sleeve 1 and the first reinforcing bar 9, and effectively adapting to reinforcing bar structures of different specifications and sizes.

[0029] like Figure 4 As shown, in this technical solution, the outer surface of the pressure spring 13 is designed as an arc-shaped structure, and an arc-shaped groove is provided at the end of the inner clamping block 11 to cooperate with it. Then, after the rotating collar 12 drives the pressure spring 13 to rotate to a certain angle, the pressure spring 13 can engage with the arc-shaped groove at the end of the inner clamping block 11. By utilizing the corresponding degree of elastic deformation of the pressure spring 13, the movement of the inner clamping block 11 inward is controlled based on the specifications and dimensions of the steel reinforcement structure, which effectively improves the adaptability of the steel reinforcement welding device.

[0030] In this technical solution, the welding gun head 7 and the bracket 6 are fixedly connected by bolts. Then, the deflection angle of the welding gun head 7 is adjusted according to the size of the first reinforcing bar 9 so that the intersection of the central axes of the two sets of welding gun heads 7 is located on the tangent between the first reinforcing bar 9 and the second reinforcing bar 10.
