[0002] The welding and fixing device for steel bars with special-shaped surfaces for road and bridge construction is a device used to weld and fix steel bars with irregular or special shapes in road and bridge construction. This device is usually composed of a clamp, a support frame and welding equipment. It is used to accurately position and fix the steel bars with special surfaces in a predetermined position, and then firmly connect them through a welding process to ensure the stability and safety of the structure.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a welding and fixing device for steel bars used in road and bridge construction with special-shaped surface limitation, comprising a support plate 1, a round block 2 is fixedly connected to the upper surface of the support plate 1, a fixing plate 3 is fixedly connected to one side of the outer wall of the round block 2, a motor 4 is fixedly connected to the upper surface of the fixing plate 3, a rotating block 5 is fixedly connected to the output end of the motor 4, the outer wall of the rotating block 5 is rotatably connected to the outer wall of the round block 2, a sliding block 6 is fixedly connected to one side of the outer wall of the rotating block 5, a limiting groove 16 is provided inside the round block 2, one side of the outer wall of the sliding block 6 is slidably connected to the inside of the limiting groove 16, a groove 13 is provided inside the sliding block 6, a clamping block 2 14 is slidably connected inside the groove 13, a hydraulic rod 2 15 is arranged inside the sliding block 6, the output end of the hydraulic rod 2 15 is fixedly connected to one side of the outer wall of the clamping block 2 14, a fixing block 3 17 is provided on one side of the outer wall of the round block 2, and a fixing component is arranged inside the fixing block 3 17.

[0022] Specifically, the sliding block 6 connected to the rotating block 5 is driven by the motor 4 to adjust the angle, which is more precise and labor-saving than the manual adjustment machine, and the armrest 18 connected to the support plate 1 can also facilitate the transportation and operation of the device. A part of the sliding block 6 slides inside the limit groove 16 opened in the round block 2, which can increase the stability of the device and improve the quality of welding.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The fixing assembly includes a fixing block 7, one side of the outer wall of the fixing block 7 is fixedly connected to the inside of the fixing block 3 17, the fixing block 7 is rotatably connected to a rotating rod 2 10, the fixing block 3 17 is provided with a hydraulic rod 1 8, the output end of the hydraulic rod 8 is fixedly connected to a fixing block 2 9, the fixing block 29 is rotatably connected to a rotating rod 11, a groove 2 19 is provided inside the rotating rod 2 10, the outer wall of the rotating rod 11 is rotatably connected to the inside of the groove 2 19, the rotating rod 2 10 is fixedly connected to a clamping block 12, and the upper surface of the support plate 1 is fixedly connected to a handrail 18.

[0024] Specifically, the hydraulic rod 18 drives the rotating rod 11 inside the fixed block 9 to rotate, so that the rotating rod 10 can drive the clamping block 12 to firmly fix the front end of the steel bar, ensuring that the welding angle is always fixed, avoiding the gravity at the rear end of the steel bar pulling the steel bar, resulting in poor welding quality and easy breakage, and the hydraulic rod 15 driven by the clamping block 14 inside the auxiliary groove 13 achieves the effect of multiple fixation, thereby improving the processing efficiency.

[0025] Working principle: When it is necessary to use the steel bar welding fixing device for road and bridge construction with special-shaped surface limitation, first, the sliding block 6 connected to the rotating block 5 is driven by the motor 4 to rotate on the outer wall of the round block 2, so as to achieve the effect of adjusting the welding angle. Compared with other manually adjusted devices, this adjustment method is more stable and accurate. The groove 13 arranged inside the sliding block 6 and the fixed block 3 17 can limit the steel bar within a specific range. The sliding block 6 drives one of the steel bars to adjust the angle. The clamping block 2 14 inside the groove 13 can drive the hydraulic rod 2 15 to fix the steel bar, which is convenient for workers to perform welding work. Then, the fixed block 2 9 is driven to move by the hydraulic rod 1 8 so that the fixed block 2 9 can drive the clamping block 12 connected to the rotating rod 11 to rotate, so as to further fix the steel bar. If this section of the welding part of the steel bar is not completely fixed, then the welded steel bar will have errors, resulting in waste, or it cannot withstand the pressure at the rear end during welding, resulting in breakage, resulting in low work efficiency. Fixing the steel bar multiple times can achieve the effect of improving the quality of welding work. The handrail 18 connected to the support plate 1 can facilitate the staff to move the device.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
