Description

Technical Field

[0002] During the process of bridge construction, steel is widely used. Usually, steel is used to reinforce the bridge structure or facilitate the bridge formwork with the steel structure. Before the steel is officially used, welding work on the steel usually needs to be carried out according to the actual situation to make it meet the use standards. Generally, two square or circular steels are welded to extend their use lengths.

[0003] However, traditional welding work usually needs to be carried out manually, which is not conducive to improving work efficiency. The traditional welding device aligns two adjacent steels and then welds them. However, due to the reasons of the lengths and initial positions of two adjacent steels, the midpoint will shift after the two adjacent steels are aligned, affecting the welding accuracy.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] Such as Figures 1 - 11As shown in the figure, a steel welding device for bridge construction includes a base 1, two first transmission mechanisms 2, a second transmission mechanism 3, and a welding mechanism 4. An adjustment structure 5 is provided on the top of the base 1;

[0037] The adjustment structure 5 includes a gantry 8 and two first electric telescopic rods 9. Both the gantry 8 and the first electric telescopic rods 9 are provided on the top of the base 1. One end of the two first electric telescopic rods 9 is fixedly connected through a workbench 10. A first bidirectional lead screw 11 is rotatably provided inside the gantry 8. One end of the first bidirectional lead screw 11 penetrates through the gantry 8 and is fixedly connected to the output shaft of a first motor 12. Two first sliders 13 are slidably provided on the outside of the first bidirectional lead screw 11. A second electric telescopic rod 14 is provided at the bottom of the first slider 13, and one end of the second electric telescopic rod 14 is fixedly connected to a storage rack 15. A first fixing block 16 is fixedly provided on the outside of the storage rack 15. A gear ring 17 is rotatably provided inside the storage rack 15. A first fixing block 16 is rotatably penetrated through by a gear transmission member 18. The gear transmission member 18 is meshed with the gear ring 17, and one end of the gear transmission member 18 is fixedly connected to the output shaft of a second motor 19. Four first electric push rods 20 are provided inside the gear ring 17, and a support plate 21 is fixedly provided at one end of the first electric push rod 20.

[0038] The adjustment structure 5 can convey two adjacent steel materials and make one end of two adjacent steel materials contact the outside of the baffle 29, so that it is located at the center position of the welding device, which is convenient for improving the final welding accuracy, facilitating the feeding of the steel materials, and preventing the aligned work from being affected by the different lengths of the steel materials after feeding, thus affecting the final welding result.

[0039] In this embodiment, two guide rods are fixedly provided inside the gantry 8. Two convex blocks are fixedly provided on the outside of the first slider 13, and the guide rods penetrate through the convex blocks.

[0040] The cooperation between the guide rods and the convex blocks can share the load-bearing pressure on the first bidirectional lead screw 11.

[0041] In this embodiment, two fixing plates 22 are fixedly provided on the outside of the first transmission mechanism 2. A second electric push rod 23 is provided on one side of the fixing plate 22, and one end of the second electric push rod 23 penetrates through the fixing plate 22 and is fixedly connected to a first fixing frame 24. Three guide rollers 25 are rotatably provided inside the first fixing frame 24.

[0042] Under the action of the second electric push rod 23, the guide rollers 25 play a guiding and limiting role on the steel materials passing through the first transmission mechanism 2, which can prevent the steel materials from shifting during transmission and affecting the subsequent alignment work of the steel materials.

[0043] In this embodiment, both the first transmission mechanism 2 and the second transmission mechanism 3 are provided on the top of the base 1, and the welding mechanism 4 is provided on the top of the gantry 8.

[0044] The first transmission mechanism 2 transports the steel materials to be welded, and the second transmission mechanism 3 transports the welded steel materials.

[0045] In this embodiment, a limiting structure 6 is provided on the top of the workbench 10. The limiting structure 6 includes a second fixing block 26 which is fixedly connected to the workbench 10. A third motor 27 is arranged outside the second fixing block 26, and the output shaft of the third motor 27 penetrates through the second fixing block 26 and is fixedly connected to a first gear 28. A baffle 29 is rotatably arranged inside the second fixing block 26, and a second gear 30 is fixedly connected to the outside of the baffle 29. The second gear 30 is meshed with the first gear 28.

[0046] The limiting structure 6 can align two adjacent steel materials, so that the steel materials are fixed on the workbench 10 by the limiting plate 36, which has a constraining effect on aligning two adjacent steel materials, enabling two adjacent steel materials to be located at the central position of the welding device. At the same time, the position of the baffle 29 can be rotated as needed so that it does not interfere with the welding work of the welding mechanism 4 and the steel materials, and it is also convenient to place the welded steel materials on the workbench 10.

[0047] In this embodiment, a T-shaped plate 31 is fixedly arranged on the outside of the baffle 29. Fixing frames two 32 are fixedly arranged at both ends of the T-shaped plate 31. A second bidirectional lead screw 33 is rotatably arranged inside the fixing frames two 32. One end of the second bidirectional lead screw 33 penetrates through the fixing frames two 32 and is fixedly connected to the output shaft of a fourth motor 34. Two sliders two 35 are slidably arranged on the outside of the second bidirectional lead screw 33, and a limiting plate 36 is fixedly arranged on the outside of the sliders two 35.

[0048] The limiting plate 36, the second bidirectional lead screw 33, the fourth motor 34, and the sliders two 35 cooperate with the limiting structure 6 to restrict and fix two adjacent steel materials on the workbench 10, so that the steel materials are fixed on the workbench 10, facilitating the subsequent feeding work and enabling the steel materials to be located inside the gear ring 17.

[0049] In this embodiment, the second fixing block 26 is penetrated by the second gear 30. In the initial state, the top of the workbench 10 is at the same horizontal position as the tops of the first transmission mechanism 2 and the second transmission mechanism 3.

[0050] The matching of the horizontal positions of the workbench 10, the first transmission mechanism 2, and the second transmission mechanism 3 respectively facilitates the transmission work of the steel materials.

[0051] In this embodiment, the limiting plate 36 is composed of a U-shaped plate and two square plates. In the initial state, the bottom of the limiting plate 36 is higher than the top of the workbench 10.

[0052] The limiting plate 36 plays a role in restricting the position of the steel materials on the workbench 10.

[0053] In this embodiment, a discharging structure 7 is arranged outside the workbench 10. The discharging structure 7 includes two mounting plates 37 and two movable plates 38. The mounting plates 37 are fixedly connected to the bottom of the workbench 10. The two movable plates 38 are fixedly connected through a rotating shaft 40. The rotating shaft 40 is rotatably penetrated through the workbench 10. The mounting plate 37 is rotatably connected to the movable plate 38 through an electric telescopic rod three 41.

[0054] The discharging structure 7 cooperates with the second transmission mechanism 3 to move the welded steel from the surface of the workbench 10 to the second transmission mechanism 3 for transmission work after the steel welding is completed, improving the overall linkage of the welding device.

[0055] In this embodiment, a bottom plate 39 is fixedly arranged outside the mounting plate 37. In the initial state, the bottom of the movable plate 38 is flush with the top of the bottom plate 39.

[0056] The bottom plate 39 supports and limits the position of the movable plate 38.

[0057] It should be noted that the present invention is a steel welding device for bridge construction. Before use, place the device in the required place and place the circular or rectangular steel on the corresponding first transmission mechanism 2 to make it reach the operating conditions. In addition Figure 1 is the initial state of the welding device;

[0058] In the initial state, start the first transmission mechanism 2 to make the corresponding circular or rectangular steel transmit towards the workbench 10. Start the second electric push rod 23 to stop after the guide roller 25 contacts the outside of the circular or rectangular steel. The guide roller 25 plays a role in guiding and limiting the circular or rectangular steel. When one end of the two circular or rectangular steels contacts the baffle 29, start the fourth motor 34 to make the second slider 35 drive the limiting plate 36 to move towards the middle position of the second bidirectional lead screw 33 outside the second bidirectional lead screw 33 until the limiting plate 36 contacts the steel and stops. At this time, the steel is limited, and one end of the two steels contacts the outside of the baffle 29. The baffle 29 is located at the center position of the device. At this time, start the first motor 12 to make the two first sliders 13 move towards both sides of the gantry 8 outside the first bidirectional lead screw 11 to a predetermined position and stop. At this time, the distance between the two storage racks 15 reaches the maximum. Start the first electric telescopic rod 9 to make the workbench 10 move up with the two fixed steels until the workbench 10 moves up to a predetermined height and stops. Then start the second electric telescopic rod 14 to make the storage rack 15 move down to a predetermined height and stop. Then move the two storage racks 15 towards the middle position to a predetermined position and stop through the first motor 12. At this time, the steel is located inside the corresponding gear ring 17. Then start the first electric push rod 20 to stop after the support plate 21 fits with the outside of the steel. At this time, the steel is completely fixed by the support plate 21;

[0059] The slider two 35 is moved to the initial position by the motor four 34 to release the restrictive constraint on the steel. The motor three 27 is started, causing the gear one 28 to drive the gear two 30 to engage in a meshing motion until the baffle 29 rotates 90 degrees and then stops. At this time, the baffle 29 is perpendicular to the workbench 10, and the limit plate 36 and the T-shaped plate 31 do not obstruct the steel. After the workbench 10 is lowered back to the initial position by the electric telescopic rod one 9 and then stops, the motor one 12 is started to move the two steel materials towards the middle until they are in full contact and then stop. At this time, the contact position of the two steel materials is at the middle position of the welding device. Then, the motor two 19 is started to cause the gear transmission part 18 to drive the gear ring 17 to engage in a meshing motion, causing the fixed steel material to start rotating. Then, the welding mechanism 4 is started to weld the connection of the rotating steel materials;

[0060] After the welding of the steel is completed, the motor two 19 is stopped to make the steel stop rotating. The welded steel is lowered to a predetermined height by the electric telescopic rod two 14 and then stops. The workbench 10 is lifted by the electric telescopic rod one 9 until the top of the workbench 10 contacts the welded steel and then stops. The pallet 21 is returned to the initial position by the electric push rod one 20 and then stops. Then, the motor one 12 is started to move the slider one 13 towards both ends until the distance between the two storage racks 15 reaches the maximum value and then stops. At this time, the welded steel is located on the top of the workbench 10 and is no longer inside the gear ring 17. The workbench 10 is lowered to the initial position by the electric telescopic rod one 9 and then stops. The electric telescopic rod three 41 and the transmission mechanism two 3 are started to make the two movable plates 38 flip towards the transmission mechanism two 3. The welded steel on the top of the workbench 10 moves towards the transmission mechanism two 3 under the action of the movable plates 38 and is finally conveyed away by the transmission mechanism two 3, thus completing the feeding, welding, and discharging operations of two adjacent steel materials.
