As an important facility to ensure the safety of people and objects, the quality and stability of guardrails are of paramount importance. Square tubes have become a commonly used material for making guardrails due to their good strength, corrosion resistance, and aesthetics. In the process of making guardrails, welding is the key process for connecting square tubes.

[0003] In the welding of square tubes for guardrails, electric welding machines are typically used, and the welding torch on the machine needs to be manually held to weld the joints of the square tubes. If the square tubes are manually supported and positioned during welding, the positioning of the tubes can easily become unstable, which may seriously affect the welding quality and significantly reduce the overall stability of the guardrail structure. Therefore, a welding support and fixing bracket for square tubes is needed to provide support for the square tubes during welding, thereby effectively ensuring the stability and quality of the welding.

[0020] In the following description, embodiments of the protective railing square tube welded support and fixing bracket of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4This invention illustrates a welded support bracket for a guardrail made of square tubes, comprising a base 3 disposed at the bottom of two square tubes 1 and 2. Two square tubes 1 are present. Two symmetrical uprights 4 are fixedly connected to the top of the base 3. Two symmetrical reinforcing plates 15 are fixedly connected to the surface of the uprights 4. The reinforcing plates 15 are welded to the base 3. The reinforcing plates 15 are wedge-shaped and inclined. A U-shaped right-angle plate is fixedly connected to the top of the base 3. A longitudinal scale 14 is fixedly connected to the top of the base 3. The scale 14 and the reinforcing plates 15 work together to... When the output shaft of motor 13 drives the threaded rod 7 to rotate via bevel gear 11 and bevel gear 12, the threaded rod 7 drives the limiting slider 10 to move downward, which in turn drives the support plate 9 to move downward. This allows the support plate 9 to easily descend to the appropriate position according to the scale on the ruler 14, thus facilitating the control of the distance between adjacent square tubes 2 during welding and improving the stability of the bracket. The top of the ruler 14 is fixedly connected to the bottom of the fixing plate 6, and the top of the base 3 is fixedly connected to two symmetrical limiting grooves 5. The bottom of square tube 1 is located in the inner cavity of the limiting groove 5. Square tube 1 is adapted to the limiting groove 5, which is fixedly connected to the column 4 by welding. A fixing plate 6 is provided on the top of the base 3, and is fixedly connected to the column 4 by welding. A threaded rod 7 is rotatably connected to the top of the base 3 via a rotating shaft, and is rotatably connected to the fixing plate 6 via the rotating shaft. The top end of the threaded rod 7 extends through to the top of the fixing plate 6. Two symmetrical limiting rods 8 are fixedly connected to the top of the base 3, and are fixedly connected to the fixing plate 6. A support plate 9 is provided at the bottom of square tube 2, and both ends of square tube 2 are in contact with the surface of square tube 1. Three equidistant limiting sliders 10 are fixedly connected to the back of the support plate 9. A threaded rod 7 passes through the limiting slider 10 and is threadedly connected to the limiting slider 10. A limiting rod 8 passes through the limiting slider 10 and is slidably connected to the limiting slider 10. A bevel gear 11 is provided on the top of the fixed plate 6. One end of the bevel gear 11 is fixedly connected to the top of the threaded rod 7. A bevel gear 12 is provided on the top of the fixed plate 6. The bevel gear 12 meshes with the bevel gear 11. A motor 13 is fixedly installed on the top of the fixed plate 6. The output shaft of the motor 13 is fixedly connected to one end of the bevel gear 12.

[0022] Working Principle: When using this utility model, the user places the square tube 11 inside the limiting groove 5, then starts the motor 13. The output shaft of the motor 13 drives the bevel gear 12 to rotate. Because the bevel gear 11 meshes with the bevel gear 12, the bevel gear 12 drives the bevel gear 11 to rotate, which in turn drives the threaded rod 7 to rotate. The threaded rod 7, through the limiting rod 8, drives the limiting slider 10 to move downward, causing the limiting slider 10 to drive the support plate 9 to move downward. When the support plate 9 moves to the appropriate position, the square tube 22 is placed horizontally on top of the support plate 9 and moved, causing the square tube 22 to... The left and right ends of the bracket are attached to the square tube 1 at the appropriate welding point, which can provide support for the square tube during welding, thereby effectively ensuring the stability and quality of the welding. With the cooperation of the scale 14 and the reinforcing plate 15, when the output shaft of the motor 13 drives the threaded rod 7 to rotate through the bevel gear 11 and bevel gear 2 12, the threaded rod 7 drives the limit slider 10 to move downward, which in turn drives the support plate 9 to move downward. This allows the support plate 9 to easily descend to the appropriate position according to the scale on the scale 14, thereby facilitating the control of the distance between adjacent square tubes 2 and improving the stability of the bracket during welding.

[0023] In summary, this protective railing square tube welding support bracket works by placing square tube 1 inside the limiting groove 5, then driving the output shaft of motor 13 to rotate bevel gear 12, which in turn drives bevel gear 11, which in turn drives threaded rod 7, which in turn drives limiting slider 10 downward through limiting rod 8. This causes limiting slider 10 to drive support plate 9 downward. When support plate 9 is in the appropriate position, square tube 2 is placed horizontally on top of support plate 9, thus providing support for the square tube during welding and effectively ensuring the stability and quality of the welding.
