[0001] The present invention relates to the technical field of welding equipment, and particularly relates to a welding device for the production of electric power poles and towers. Background Art

[0002] Poles and towers are supports for power transmission lines, mostly made of steel. To ensure their stability and to set up the power transmission lines, there are many connecting rods on the poles and towers. These connecting rods are generally made of steel after rolling, and then the gaps are welded. Since the welded part is a continuous straight line, it is also called straight seam welding. In the prior art, when welding the side plates of electric power poles and towers, it is necessary to first splice and fix adjacent side plates and then weld them. However, after welding one side, it is necessary to disassemble the side plates, turn them over and fix them again, and then weld the other side. Such operations are relatively cumbersome.

Specific embodiments

[0018] 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 embodiments.

[0019] Example 1, as shown in Figure 1-2As shown in the figure, a welding device for the production of electric power poles includes two base plates 3. The upper ends of the two base plates 3 are fixedly connected to a machine shell 1 together. In the middle of the front end of the machine shell 1, an observation window 2 is opened. On the left side of the inner bottom wall of the machine shell 1, a conveying mechanism 4 is provided. On the right side of the inner bottom wall of the machine shell 1, a fixing mechanism 5 is provided. On the right side of the inner top wall of the machine shell 1, a mechanical welding arm 6 is fixedly connected.

[0020] It should be noted that the specific installation method, the connection method of the circuit and the control method of the mechanical welding arm 6 in the present invention are all conventional designs, which are the conventional design means of designers. Moreover, the mechanical welding arm 6 is composed of a mechanical arm and a welding torch, and they can cooperate with each other to realize the welding of the tower feet of the poles.

[0021] First, place the steel vertical plate and two steel horizontal plates used to make the tower feet of the poles into the fixing mechanism 5 to a proper position. Fix the steel horizontal plates on the front and back sides through the fixing mechanism 5. Then, weld the splicing part of the steel vertical plate and the steel horizontal plate through the mechanical welding arm 6. After welding one place, rotate it to a proper position through the fixing mechanism 5 and then weld the splicing part through the mechanical welding arm 6 until the welding of the four splicing parts is completed. While transporting the welded tower feet of the poles to the conveying mechanism 4 through the fixing mechanism 5, grind and remove the welding slag at the lower welding part. Transport the tower feet of the poles to the outside of the device through the conveying mechanism 4, and at the same time, grind and remove the welding slag at the upper welding part.

[0022] To complete the fixation of the steel vertical plate and the two steel horizontal plates used to make the tower feet of the poles, as Figure 3 shown, the fixing mechanism 5 includes a lower bottom plate 51. In the middle of the upper end of the lower bottom plate 51, a driving component two 591 is fixedly connected. On the left and right sides of the upper end of the lower bottom plate 51, circular mounting frames 52 are fixedly connected. On the opposite surfaces of the two circular mounting frames 52, mounting grooves one 53 are opened. In the inner cavities of the two mounting grooves one 53, gear rings 54 are rotatably connected. On the upper sides of the inner walls of the two gear rings 54, a U-shaped plate 55 is fixedly connected together. On the lower sides of the inner walls of the two gear rings 54, a support group 57 is fixedly connected together. On the front and back sides of the support group 57, pressure groups 56 are provided. In the middle of the support group 57 and the inner cavity of the U-shaped plate 55, a tower foot 592 of the pole is provided. The outer surfaces of the two gear rings 54 are meshed with a transmission component five 58 together. On the left and right sides of the outer surface of the transmission component five 58, a rotating bracket three 59 is rotatably connected together. The middle part of the outer surface of the transmission component five 58 is wound with a belt around the driving component two 591. The lower ends of the two rotating brackets three 59 are fixedly connected to the upper end of the lower bottom plate 51 together. The lower end of the lower bottom plate 51 is fixedly connected to the right side of the inner bottom wall of the machine shell 1.

[0023] It should be noted that the driving component II 591 is composed of a driving motor and a pulley. The specific installation method, circuit connection method, and control method of the driving motor are all conventional designs and are the conventional design means of designers. In addition, the transmission component V 58 is composed of a rotating shaft, a pulley, and two gears. The pulley in the transmission component V 58 is connected to the pulley in the driving component II 591 through a belt.

[0024] First, place the steel vertical plate at a suitable position between the inner cavity of the U-shaped plate 55 and the support group 57. Then, place the two steel horizontal plates at suitable positions on the front and back sides of the support group 57 and clamp and fix them through the pressing group 56, so as to splice the two steel horizontal plates at suitable positions on both sides of the steel vertical plate. Use the mechanical welding arm 6 to weld the splicing part at the upper part of the rear side. After welding is completed, start the driving component II 591, and drive the transmission component V 58 to rotate in the inner cavities of the two rotating brackets III 59 through the cooperation of the belt. Drive the two toothed rings 54 to rotate backward to a suitable angle in the inner cavity of the mounting groove I 53 respectively through the rotation of the transmission component V 58. Then, through the cooperation of the U-shaped plate 55 and the support group 57, make the two steel horizontal plates and the steel vertical plate rotate together to a suitable position. Then use the mechanical welding arm 6 to weld the splicing part. After welding is completed, repeat the above operations until all four splicing parts are welded. Finally, the purpose of fixing the steel vertical plate and the two steel horizontal plates for making the tower foot of the tower and completing the welding in cooperation with the mechanical welding arm 6 is achieved, making the welding of the device more flexible.

[0025] Further explanation, as Figure 4 and Figure 5 shown, the support group 57 includes a fixed bracket 571. Both the front and rear sides of the middle part of the upper end of the fixed bracket 571 are fixedly connected with side plates 572. Both the front and rear sides of the upper end of the fixed bracket 571 are fixedly connected with connecting plates 574. Roller 573 is provided in the middle of the upper end of each of the two connecting plates 574. Mounting groove II 575 is opened on the side far from each other in the middle of the upper end of each of the two connecting plates 574. The left part of the upper side of the inner cavity of the fixed bracket 571 is provided with symmetrically arranged abrasive plates 576 in the front and back. The left and right sides of the lower end of the fixed bracket 571 are respectively fixedly connected with the two toothed rings 54. The inner cavity of the fixed bracket 571 is slidably connected with the lower end of the tower foot 592 of the tower.

[0026] Specifically, the frosted plate 576 is fixed to the fixed bracket 571 by bolts. Grooves are provided at the upper ends of the two connecting plates 574, and rollers 573 are installed in the inner cavities of the grooves to facilitate the movement of the two steel cross plates thereon. The two pressurizing groups 56 are installed through the two second installation grooves 575. After the steel vertical plate is placed at a suitable position between the inner cavity of the U-shaped plate 55 and the inner cavity of the fixed bracket 571, then the two steel cross plates are respectively placed at suitable positions on the upper ends of the two connecting plates 574. The two steel cross plates are clamped and fixed by the pressurizing groups 56 on the front and rear sides, and the welding operation is completed in cooperation with the mechanical welding arm 6. After the welding is completed, the pressurizing groups 56 drive the tower foot to move to the left in cooperation with the rollers 573, and the slag at the two lower welding joints is polished by the two pressurizing groups 56.

[0027] Further description is as Figure 6 and Figure 7 shown. On the left sides of the upper ends of the two T-shaped plates 561 close to each other, a first motor 564 is fixedly connected to each. Output ends of the two first motors 564 are fixedly connected to second transmission wheels 565. Installation grooves three 567 are provided at the upper ends of the two T-shaped plates 561. Rotating wheels 563 that are symmetric left and right are rotatably connected to the inner cavities of the two installation grooves three 567. One ends of the two rotating wheels 563 on the same side are respectively fixedly connected to a first transmission wheel 562 and a third transmission wheel 566. The outer surface of the first transmission wheel 562 on the same side is connected to the third transmission wheel 566 by a belt, and the outer surface of the second transmission wheel 565 on the same side is connected to the third transmission wheel 566 by a belt. On the upper side walls of the lower ends of the two T-shaped plates 561, hydraulic cylinders 568 are fixedly connected. Opposite surfaces of the two hydraulic cylinders 568 are respectively fixedly connected to the middle parts of the front and rear ends of the two connecting plates 574. The middle parts of the outer surfaces of the two T-shaped plates 561 are respectively slidably connected to the inner cavities of the two second installation grooves 575.

[0028] It should be noted that the specific installation methods, connection methods of the circuits, and control methods of the first motor 564 and the hydraulic cylinder 568 in the present invention are all conventional designs and are the conventional design means of designers.

[0029] Specifically, when two steel cross plates are placed at the appropriate positions on the connecting plate 574, by starting the hydraulic cylinder 568, the hydraulic cylinder 568 drives the T-shaped plate 561 to slide downward in the inner cavity of the second installation groove 575, so that the T-shaped plate 561 tightly presses the steel cross plates. After the welding is completed at the four splicing joints, after the two gear rings 54 rotate reversely to restore the initial position, then start the first motor 564, and the first motor 564 drives the second transmission wheel 565 to rotate. Through the rotation of the second transmission wheel 565 and the cooperation of the belt, the third transmission wheel 566 and the rotating wheel 563 rotate simultaneously. Furthermore, the rotating wheel 563 drives the welded tower foot to be transported to the left in cooperation with the roller 573, and the welding slag at the lower welding part is polished and removed by the grinding plate 576, so that the pressing group 56 can not only clamp and fix the steel cross plates but also transport them after the welding is completed.

[0030] Embodiment 2. On the basis of Embodiment 1, this embodiment completes the transportation of the tower foot and the removal of the welding slag at the upper welding part. As Figure 8 and Figure 9 shown, the conveying mechanism 4 includes a U-shaped base frame 41. Both the front and rear sides of the upper end of the U-shaped base frame 41 are fixedly connected with U-shaped bottom plates 44. A number of transport wheels 49 are arranged in the inner cavities of the two U-shaped bottom plates 44. One end of a number of transport wheels 49 on the same side penetrates through the inner cavity of the U-shaped bottom plate 44 and is fixedly connected with a sprocket 46. The outer surfaces of a number of sprockets 46 on the same side are jointly meshed and connected with a chain 47. The right sides of the front and rear ends of the U-shaped base frame 41 are jointly connected with a grinding group 48. One end of the two transport wheels 49 located on the left side away from each other is fixedly connected with a fourth transmission wheel 45. The left side of the outer surface of the U-shaped base frame 41 is rotatably connected with a first transmission component 42. The rear end of the first transmission component 42 is fixedly connected with a second motor 43. The outer surfaces of the two fourth transmission wheels 45 are respectively connected with the front and rear sides of the first transmission component 42 through belts. The lower end of the U-shaped base frame 41 is fixedly connected with the bottom wall of the inner cavity of the machine shell 1, and the lower end of the second motor 43 is fixedly connected with the bottom wall of the inner cavity of the machine shell 1.

[0031] It should be noted that the specific installation method, the connection method of the circuit and the control method of the second motor 43 in the present invention are all conventional designs and are the conventional design means of designers. In addition, one end of the two transport wheels 49 located on the leftmost side away from each other sequentially penetrates through the inner cavity of the U-shaped bottom plate 44 on the same side and the sprocket 46 and is fixedly connected with a fourth transmission wheel 45. The first transmission component 42 is composed of a rotating shaft and two belt wheels adapted to the fourth transmission wheel 45.

[0032] First, when the tower foot after welding is transported to the rightmost transport wheel 49, by starting the second motor 43, the first transmission component 42 is driven by the second motor 43 to rotate. With the cooperation of the belt, the fourth transmission wheel 45, the transport wheel 49, and the sprocket 46 located on the leftmost side are driven to rotate simultaneously. With the cooperation of the chain 47, a number of sprockets 46 drive a number of transport wheels 49 to rotate simultaneously, finally driving the tower foot to be transported to the left. At the same time, with the cooperation of the grinding group 48, the welding slag on the upper side of the tower foot is ground to remove the slag.

[0033] Further explanation, as Figure 10 shown, the grinding group 48 includes a ceiling frame 481. On the left side of the upper end of the ceiling frame 481, two rotating brackets two 487 are fixedly connected. Inside the cavities of the two rotating brackets two 487, a fourth transmission component 486 is rotatably connected. In the middle of the upper end of the ceiling frame 481, a first driving component 485 is fixedly connected. The upper end of the first driving component 485 is wound and connected to the fourth transmission component 486 through a belt. On the top wall of the inner cavity of the ceiling frame 481, symmetrically arranged front and rear connecting brackets 482 are fixedly connected. Inside the cavities of the two connecting brackets 482, symmetrically arranged left and right third transmission components 483 are rotatably connected. On the opposite surfaces of the two front and rear symmetric third transmission components 483, grinding wheels 484 are fixedly connected. On the sides of the two third transmission components 483 on the same side away from the grinding wheels 484, they are connected through a belt. The front and rear sides of the outer surface of the fourth transmission component 486 are respectively connected to the two third transmission components 483 on the left side through a belt. The lower side of the outer surface of the ceiling frame 481 is fixedly connected to the right side of the outer surface of the U-shaped base frame 41.

[0034] It should be noted that the first driving component 485 is composed of a driving motor and a pulley. The specific installation method, circuit connection method, and control method of the driving motor are all conventional designs, which are the conventional design means of designers. The fourth transmission component 486 is composed of a rotating shaft and three pulleys. The pulley in the first driving component 485 is connected to the middle pulley in the fourth transmission component 486 through a belt. The third transmission component 483 is composed of a rotating shaft and a pulley. The pulley in the third transmission component 483 on the left side is connected to the pulley in the fourth transmission component 486 through a belt. The pulleys in the two third transmission components 483 on the same side, front and rear, are connected through a belt.

[0035] Specifically, by starting the first driving component 485, with the cooperation of the belt, the fourth transmission component 486 is driven to rotate inside the rotating bracket two 487. Through the rotation of the fourth transmission component 486 and the cooperation of the belt, the third transmission component 483 drives the grinding wheel 484 to rotate inside the connecting bracket 482. Through the rotation of the grinding wheels 484 on the front and rear sides, the welding slag at the welding part of the tower foot is ground to remove the slag, achieving the purpose of removing the slag.
