DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] like Figures 1 to 10 As shown, a steel structure bridge welding device described in an embodiment of the present invention includes a welding body 1, a moving component for moving the welding device; a lifting component for clamping and moving the U-shaped rib; an unloading component for unloading the welded bridge deck steel plate; a pushing component for pushing the welding device to move; and an adjusting component for adjusting the angle of the welding device. The moving component includes an electric screw rod 2 rotatably connected to the middle part of one side of the inner wall of the welding body 1, and the outer wall of the electric screw rod 2 is threadedly connected to a moving platform 3, and the bottom of the moving platform 3 is slidably connected to the bottom of the inner wall of the welding body 1, and the inner wall of the welding body 1 is fixedly connected to guide rods 4 on both sides close to the electric screw rod 2, and the outer wall of the guide rod 4 is connected to the moving platform 3 is slidably connected to one end of the inner wall of the movable platform 3, and the lifting platform 6 is fixedly connected to the top of the lifting platform 6, and the output end of the lifting platform 6 is fixedly connected to the lifting platform 7, and the two ends of the bottom of the lifting platform 7 are fixedly connected to the electric telescopic clamp 8, and the output end of the electric telescopic clamp 8 is overlapped with the U rib 9, the unloading component includes a placing table 10 fixedly connected to one side of the outer wall of the welding body 1, and one end of the top of the placing table 10 is fixedly connected to the placing bin 11, one side of the inner wall of the placing bin 11 is rotatably connected to the electric turning frame 12, and a bridge panel 13 is placed on the top of the electric turning frame 12, and the top of the bridge panel 13 is overlapped with the bottom of the U rib 9.

[0042] During operation, a placement table 10 is set on one side of the outer wall of the welding body 1, and a number of U-ribs 9 are placed in a placement bin 11 set at one end of the top of the placement table 10. An electric-controlled flip frame 12 is set on one side of the inner wall of the placement table 10, and a bridge panel 13 is placed on the surface of the electric-controlled flip frame 12. Then, the electric screw 2 set in the middle of one side of the inner wall of the welding body 1 is started, and the electric screw 2 cooperates with the guide rods 4 set on both sides of the inner wall of the welding body 1 close to the electric screw 2, so that the moving table 3 set on the outer wall slowly moves in the welding body 1 until it moves close to one side of the placement bin 11. An electric telescopic frame 5 is set on the top of the moving table 3, and a lifting platform 6 is set on the top of the electric telescopic frame 5. The lifting platform 6 is started to adjust the hanging platform 7 set at its output end. The height is adjusted so that the electrically controlled telescopic clamps 8 provided at both ends of the bottom of the hanging platform 7 clamp the U-rib 9 stored in the placement bin 11. Then, the electric screw rod 2 is used again to move the movable platform 3 to a suitable position, and the lifting platform 6 is started again to place the U-rib 9 clamped by the bottom of the hanging platform 7 on the surface of the bridge deck 13. At this time, the electric telescopic frame 5 is started, and the limit shell 14 provided at the output end of the electric telescopic frame 5 is extended into the U-rib 9. The electric telescopic rod 16 provided on the inner wall of the limit shell 14 is started, so that the double-sided toothed plate 17 provided at its output end is linked to the gear 18, so that the telescopic plate 19 pushes the storage box 20 provided on both sides of the outer wall of the limit box 15 to move. During this period, the motor 22 provided on the top of one side of the outer wall of the storage box 20 is started so that the extension rod 28 provided in the storage box 20 is moved. When the welding rod 28 is in the working state, the welding gun 33 is rotated to the maximum angle, and the welding gun 33 is driven to rotate during the rotation of the extension rod 28. When the storage box 20 continues to move toward the inner wall of the U rib 9, until the ball 30 in the sleeve 29 provided at one end of the outer wall of the extension rod 28 fits with the inner wall of the U rib 9, the welding gun 33 is started to weld the gap between the U rib 9 and the bridge deck 13. At the same time, the electric telescopic frame 5 is started again, and the limit box 15 is slowly pushed to move in the U rib 9, so as to achieve the purpose of welding the inner wall of the U rib 9. When all the U ribs 9 on the surface of the bridge deck 13 are welded, the electric telescopic frame 5 is closed, and the limit box 15 is withdrawn from the inner wall of the U rib 9, and the electric screw rod 2 is used to offset the moving platform 3 again so that the limit box 15 is between the U ribs 9. The electric telescopic rod 16 is started to push the double-sided gear plate 17, and the linkage gear 18 is used to push the telescopic plate 19, and the position of the storage box 20 is adjusted to align the output end of the welding gun 33 with the welding surface of the U-rib 9 and the bridge deck 13. Then the electric telescopic frame 5 is started to push the limit box 15 forward to weld the joint between the U-rib 9 and the outer wall of the bridge deck 13, which further solves the problem that the traditional steel structure bridge welding device is used. Due to the large limitations of the device for welding the U-shaped rib plate and the inner wall of the bridge deck steel plate, additional devices are often required to cooperate in the subsequent welding of the U-shaped rib plate and the surface of the bridge deck steel plate. When the welding is completed, the electric control flip frame 12 is started to make the welded bridge deck 13 slide down from the surface of the placement table 10 while keeping it tilted.It is convenient for operators to carry the bridge deck 13.

[0043] The pushing assembly includes a limit shell 14 fixedly connected to the output end of the electric telescopic frame 5, and one end of the outer wall of the limit shell 14 is fixedly connected to the limit box 15, the middle part of one side of the inner wall of the limit shell 14 is fixedly connected to the electric telescopic rod 16, and the output end of the electric telescopic rod 16 is fixedly connected to the double-sided toothed plate 17, and the upper and lower ends of the outer wall of the double-sided toothed plate 17 are slidably connected to the inner wall of the limit shell 14, and both sides of the outer wall of the double-sided toothed plate 17 are meshed with a linkage gear 18, and the upper and lower ends of the outer wall of the linkage gear 18 rotate with the outer wall of the limit shell 14. The outer wall of the linkage gear 18 is fixedly connected to a telescopic plate 19 at one end, and the upper and lower ends of the outer wall of the storage box 20 near the telescopic plate 19 are fixedly connected to an extension limit plate 21, and both sides of the outer wall of the extension limit plate 21 are slidably connected to the inner wall of the limit box 15. The adjustment component includes a motor 22 fixedly connected to the top of one side of the outer wall of the storage box 20, and the output end of the motor 22 is fixedly connected to a transmission rod 23, and one end of the transmission rod 23 is rotatably connected to the inner wall of the storage box 20. The transmission rod 23 is connected to the first gear 24 at one end of the outer wall, and the transmission rod 23 is fixedly connected to the second gear 25 at one end of the outer wall away from the first gear 24. The inner wall of the storage box 20 is rotatably connected to the support rod 26 at one end close to the transmission rod 23, and the support rod 26 is fixedly connected to the first double gear 27 at one end of the outer wall, and one side of the outer wall of the first double gear 27 is meshed with one side of the outer wall of the first gear 24. The outer wall of the first double gear 27 is fixedly connected to the end away from the first gear 24 with an extension rod 28, and the extension rod 28 is fixedly connected to the first gear 24. One end of the outer wall of the rod 28 is fixedly connected to a sleeve 29, and a ball 30 is provided on the inner wall of the sleeve 29. The bottom of the inner cavity of the sleeve 29 is slidably connected to an elastic telescopic rod 31, and one end of the elastic telescopic rod 31 overlaps the inner wall of the U rib 9. The end of the outer wall of the support rod 26 away from the first double gear 27 is fixedly connected to the second double gear 32, and one side of the outer wall of the second double gear 32 is meshed with one side of the outer wall of the second gear 25, and the end of the outer wall of the second double gear 32 away from the second gear 25 is fixedly connected to a welding gun 33.

[0044] During operation, a limit shell 14 is provided at the output end of the electric telescopic frame 5, and the limit shell 14 is used to support the limit box 15. An electric telescopic rod 16 is provided in the middle of one side of the inner wall of the limit shell 14, and the electric telescopic rod 16 is used to push the double-sided toothed plate 17 provided at its output end, so that the double-sided toothed plate 17 slides on the inner wall of the limit shell 14, and drives the linkage gears 18 provided on both sides to rotate, so that the telescopic plate 19 provided at one end of the outer wall of the linkage gear 18 pushes the storage box 20 provided at one end thereof to move. Since the outer wall of the storage box 20 is close to the upper and lower ends of the telescopic plate 19, an extended limit plate 21 is provided, and the extended limit plate 21 slides in the limit box 15, the extended limit plate 21 is used to prevent the storage box 20 from deviating when it moves toward the inner wall of the U rib 9. This causes the output end of the welding gun 33 to be misaligned. By arranging a support rod 26 on one side of the inner wall of the storage box 20 and arranging a first double gear 27 at one end of the outer wall of the support rod 26, an extension rod 28 is provided at one end of the outer wall of the first double gear 27, and a sleeve 29 is provided at one end of the outer wall of the extension rod 28, and a ball 30 is provided on the inner wall of the sleeve 29, so that the combined length of the extension rod 28, the sleeve 29 and the ball 30 is the same as the height of the storage box 20. When the storage box 20 moves toward the inner wall of the U rib 9, the motor 22 set at the top of one side of the outer wall of the storage box 20 is started, and the motor 22 drives the transmission rod 23 set at the output end to rotate, so that the transmission rod 23 drives the first gear 24 and the second gear 25 respectively set at both ends of the outer wall to rotate. The second gear 25, since the first gear 24 and the first double gear 27 are the same size, and the ratio between the first gear 24 and the second gear 25 is one to two, and one side of the outer wall of the first gear 24 is engaged with the tooth mark of the first double gear 27, when the first gear 24 rotates, it drives the first double gear 27 to rotate with the support rod 26 as the center point, and causes the first double gear 27 to drive the extension rod 28, the sleeve 29 and the ball 30 to rotate. Since the first double gear 27 and the second double gear 32 are both half gears, when the extension rod 28, the sleeve 29 and the ball 30 move to the highest point, they stop rotating. During this period, the transmission rod 23 is used to drive the second gear 25, so that the support rod 26 is away from one end of the first double gear 27 to set the second gear 25. The second double gear 32 rotates, and the welding gun 33 set at one end of it is at the center of the angle between the extension rod 28 and the storage box 20. At this time, as the telescopic plate 19 pushes the storage box 20 to move continuously, the elastic telescopic rod 31 set at the bottom of the inner cavity of the sleeve 29 is squeezed by the inner wall of the U rib 9 and re-entered into the inner cavity of the sleeve 29, and contacts the sensor set in the inner cavity of the sleeve 29. At this time, the motor 22 reverses, so that the first double gear 27 drives the extension rod 28, the sleeve 29 and the ball 30 to rotate toward the storage box 20. During this period, the second double gear 32 is driven to rotate by the second gear 25, and the welding gun 33 is always at the center of the angle between the extension rod 28 and the storage box 20. As the extension rod 28 is continuously retracted,Until the elastic telescopic rod 31 loses the restriction of the inner wall of the U rib 9 and pops out again from the sleeve 29, the sensor loses the contact of the elastic telescopic rod 31, causing the motor 22 to stop working, so that the fitting surface of the elastic telescopic rod 31 and the U rib 9 is 90 degrees. Since the inclined surface of the U rib 9, the bridge deck 13, the elastic telescopic rod 31 and the storage box 20 form a parallelogram shape at this time, it is known that the fitting surface of the elastic telescopic rod 31 and the U rib 9 is 90 degrees, and the fitting surface of the storage box 20 and the bridge deck 13 is also 90 degrees, and the internal angle of the figure is 360 degrees, so The angle between the extension rod 28 and the storage box 20, plus the angle between the U-rib 9 and the bridge deck 13, totals 180 degrees. The welding gun 33 is always positioned at the center of the angle between the extension rod 28 and the storage box 20, ensuring that the output end of the welding gun 33 is always aligned with the center of the angle between the U-rib 9 and the bridge deck 13. This further addresses the issue of conventional welding devices for steel bridge structures requiring operators to adjust the output angle of the welding device when welding the U-rib to the inner wall of the bridge deck steel plate due to differences in the specifications of the U-ribs.

[0045] A steel structure bridge welding device and method, the method adopts the above-mentioned steel structure bridge welding device, the method is as follows:

[0046] S1: Place the U-rib 9 at a suitable position on the bridge deck 13 using the lifting platform 7. Then, use the pushing assembly to move the limit box 15 into the U-rib 9. Use the adjusting assembly to ensure that the output end of the welding gun 33 is always aligned with the center of the angle between the U-rib 9 and the bridge deck 13.

[0047] S2: The pushing assembly pushes the limiting shell 14 and the limiting box 15 into the U-rib 9 through the electric telescopic frame 5, and then activates the electric telescopic rod 16. The translation distance of the storage box 20 is adjusted through the cooperation between the double-sided gear plate 17, the linkage gear 18 and the telescopic plate 19;

[0048] S3: The adjustment component drives the first gear 24 and the second gear 25 respectively provided at the two ends of the outer wall of the transmission rod 23 through the motor 22, and uses the first gear 24 and the second gear 25 to drive the first double gear 27 and the second double gear 32, so that the welding gun 33 is at the center of the angle between the extension rod 28 and the storage box 20.

[0049] The working principle of the steel structure bridge welding device and method will be specifically described below.

[0050] like Figures 1-10As shown, a placement table 10 is set on one side of the outer wall of the welding body 1, and a plurality of U-ribs 9 are placed in a placement bin 11 set at one end of the top of the placement table 10. An electric-controlled flip frame 12 is set on one side of the inner wall of the placement table 10, and a bridge panel 13 is placed on the surface of the electric-controlled flip frame 12. Then, the electric screw 2 set in the middle of one side of the inner wall of the welding body 1 is started, and the electric screw 2 cooperates with the guide rods 4 set on both sides of the inner wall of the welding body 1 close to the electric screw 2, so that the moving table 3 set on the outer wall slowly moves in the welding body 1 until it moves close to one side of the placement bin 11. An electric telescopic frame 5 is set on the top of the moving table 3, and a lifting platform 6 is set on the top of the electric telescopic frame 5. The lifting platform 6 is started to adjust The height of the hanging platform 7 set at its output end makes the electric-controlled telescopic clamps 8 set at both ends of the bottom of the hanging platform 7 clamp the U-rib 9 stored in the placement bin 11, and then the electric screw rod 2 is used again to move the movable platform 3 to the appropriate position, and then the lifting platform 6 is started again to place the U-rib 9 clamped at the bottom of the hanging platform 7 on the surface of the bridge deck 13. At this time, the electric telescopic frame 5 is started, and the limit shell 14 set at the output end of the electric telescopic frame 5 is extended into the U-rib 9, and the electric telescopic rod 16 set on the inner wall of the limit shell 14 is started, so that the double-sided toothed plate 17 set at its output end is linked to the gear 18, so that the telescopic plate 19 pushes the storage box 20 set on both sides of the outer wall of the limit box 15 to move. During this period, the top of the outer wall of the storage box 20 is started. The motor 22 rotates the extension rod 28 provided in the storage box 20 to the maximum angle, and in the process of the rotation of the extension rod 28, drives the welding gun 33 to rotate. When the storage box 20 continues to move toward the inner wall of the U rib 9, until the ball 30 in the sleeve 29 provided at one end of the outer wall of the extension rod 28 fits with the inner wall of the U rib 9, the welding gun 33 is started to weld the gap between the U rib 9 and the bridge deck 13. At the same time, the electric telescopic frame 5 is started again, and the limit box 15 is slowly pushed to move in the U rib 9, thereby achieving the purpose of welding the inner wall of the U rib 9. When all the U ribs 9 on the surface of the bridge deck 13 are welded, the electric telescopic frame 5 is closed, and the limit box 15 is withdrawn from the inner wall of the U rib 9, and the bridge deck 13 is welded. The electric screw 2 causes the movable platform 3 to shift again so that the limit box 15 is between the U ribs 9. At this time, the electric telescopic rod 16 is started again to push the double-sided toothed plate 17, and the linkage gear 18 is used to push the telescopic plate 19, and the position of the storage box 20 is adjusted so that the output end of the welding gun 33 is aligned with the welding surface of the U rib 9 and the bridge deck 13. Then the electric telescopic frame 5 is started to push the limit box 15 forward to weld the joint between the U rib 9 and the outer wall of the bridge deck 13, further solving the problem of the use of traditional steel structure bridge welding devices. Due to the large limitations of the device for welding the U-shaped rib plate to the inner wall of the bridge deck steel plate, additional devices are often required to cooperate in welding the U-shaped rib plate to the surface of the bridge deck steel plate.

[0051] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
