[0019] The following is combined with Figure 1-3This application is described in further detail.

[0020] The embodiment of the present application discloses a welding support frame for metal guardrail processing. Figure 1 , including a rectangular base 1, and a plurality of support rods 2 are fixedly connected to the lower surface of the base 1, so that the entire device is stably supported by the base 1 and the plurality of support rods 2, and a plurality of rectangular movable plates 3 are snap-connected to the upper surface of the base 1, and two arc-shaped first clamping plates 4 are slidably connected to the upper surface of the movable plate 3, so that the positions of the plurality of movable plates 3 can be moved according to the different spacings of the vertical rods of the guardrail to be welded, so that it can be suitable for fixing and supporting guardrails with different vertical rod spacings, thereby improving the versatility of the device. After adjusting the position of the movable plate 3, the vertical rod is placed on the movable plate 3, and then the vertical rod is stably fixed by relative sliding of the two first clamping plates 4, so that subsequent welding can be carried out stably, thereby improving welding efficiency and welding quality;

[0021] Secondly, two rectangular fixing seats 5 are fixedly connected to the lower surface of the base 1, and plate-shaped connecting plates 6 are slidably connected to the two side surfaces of the fixing seats 5. The connecting plates 6 on the same side of the two fixing seats 5 are fixedly connected to the side surfaces of the U-shaped rod 7. A threaded column 19 is screwed through the lower surface of the U-shaped rod 7. The lower surface of the threaded column 19 is fixedly connected to a limiting plate 20. A rectangular supporting plate 8 is fixedly connected to the upper surface of the U-shaped rod 7. Two arc-shaped second splints 9 are slidably connected to the side surface of the support plate 8 so that the crossbars of the guardrail to be welded can be placed on the two The second clamping plates 9 are then moved relative to each other to stabilize the cross bar, and the support plate 8 is then pulled inward to drive the connecting plate 6 to slide on the inner wall of the fixing seat 5. The cross bar stops when it moves to the end of the vertical bar. The threaded column 19 is then rotated to drive the limit plate 20 to move downward so that the limit plate 20 is close to the ground, thereby fixing the U-shaped rod 7 and the support plate 8, thereby fixing the cross bar, so that the vertical bar can be stably welded to the outer surface of the cross bar later, thereby improving the flexibility of the device and being suitable for welding guardrails of different heights.

[0022] Reference Figure 2A first groove-shaped slide 10 is provided on the upper surface of the movable plate 3, and a double-headed screw 11 is rotatably connected to the inner wall of the first slide 10, and the outer surface of the double-headed screw 11 is relatively screwed with the two first clamping plates 4. At the same time, two second groove-shaped slides 12 are provided on the upper surface of the movable plate 3, and a limiting column 13 of the device is fixedly connected to the inner wall of the second slide 12, and the outer surface of the limiting column 13 slides relatively with the two first clamping plates 4, so that under the limiting action of the limiting column 13 on the first clamping plate 4, the staff rotates the double-headed screw 11, thereby driving the two first clamping plates 4 to slide relatively on the upper surface of the movable plate 3, so that the vertical rod can be stably clamped and fixed, thereby avoiding displacement of the rod during welding, thereby ensuring the welding quality.

[0023] Reference Figure 3 The third guide slots 14 are provided on the upper surface of the base 1, and two T-shaped block-shaped sliders 15 are fixedly connected to the lower surfaces of the several movable plates 3, and the sliders 15 slide relative to the inner walls of the third guide slots 14. Secondly, the inner wall of the third guide slots 14 is provided with several arc-shaped slots 16, and the side surface of the slider 15 is provided with a slot-shaped mounting slot 17. The inner wall of the mounting slot 17 is elastically slidably connected with a block-shaped blocking block 18 by a spring, and the blocking block 18 can be engaged with the inner wall of any blocking slot 16, so that when the position of the movable plate 3 needs to be moved, the blocking block 18 is pressed to move it away from the inner wall of the current blocking slot 16, and then the movable plate 3 is moved, so that the slider 15 slides on the inner wall of the third guide slot 14. After moving to the appropriate position, due to the disappearance of external force, the blocking block 18 will rebound and engage with the inner wall of the corresponding blocking slot 16 under the restoring action of the spring, thereby stably fixing the movable plate 3 to prevent movement during the welding process.

[0024] The implementation principle of a welding support frame for metal guardrail processing in the embodiment of the present application is as follows: first, the cross bar of the guardrail to be welded is placed between the two second clamping plates 9, and then the two second clamping plates 9 are made to slide relative to each other to stably fix the cross bar, and then the support plate 8 on one side of the base 1 is moved according to the length of the vertical rod of the guardrail to be welded, thereby driving the connecting plate 6 to slide on the inner wall of the fixing seat 5, and after moving to the appropriate position, the threaded column 19 is rotated to drive the limit plate 20 to move downward, so that the limit plate 20 is close to the ground, thereby limiting and fixing the U-shaped rod 7 and the support plate 8, and then the positions of several movable plates 3 are moved according to the different spacings of the vertical rods of the guardrail to be welded, first pressing the block 18 to move it away from the inner wall of the current slot 16, and then moving the movable plate 3 so that the slider 15 slides on the inner wall of the third slide groove 14, and after moving to the appropriate position, due to the disappearance of external force, the block 18 will rebound and engage with the inner wall of the corresponding slot 16 under the return action of the spring, thereby The movable plate 3 is stably fixed, and then several vertical rods are placed on several movable plates 3, and one end of the vertical rod is close to the outer surface of the cross bar. Then, under the limiting action of the limiting column 13 on the first clamping plate 4, the staff rotates the double-headed screw 11, thereby driving the two first clamping plates 4 to slide relative to each other on the upper surface of the movable plate 3, so that the vertical rod can be stably clamped and fixed, thereby avoiding displacement of the rod during welding, ensuring stable welding, and being suitable for fixing guardrails with different vertical rod spacings, improving the versatility of the device. Then, the support plate 8 on the other side of the base 1 is pulled inward and stopped when it moves to make the cross bar close to the end of the vertical rod, and then the threaded column 19 is rotated to drive the limiting plate 20 to move downward, so that the limiting plate 20 is close to the ground, thereby fixing the U-shaped rod 7 and the supporting plate 8, thereby fixing the cross bar, so that the vertical rod can be stably welded to the outer surface of the cross bar later, improving the flexibility of the device, and being suitable for welding guardrails of different heights.
