Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to an automatic welding equipment for iron accessories of electric power transmission towers. Background Art

[0002] An electric power transmission tower is a tall structure used to support overhead transmission conductors in a transmission line, including tension towers, straight towers, corner towers, transposition towers, terminal towers, and crossing towers, etc. Tension towers are mainly used to limit the scope of line faults and bear the tension of conductors and overhead ground wires. Straight towers are used to support the straight section of the line and mainly bear the vertical loads of conductors and overhead ground wires. Corner towers are used at the corners of the line and bear the resultant force of conductors and overhead ground wires. Transposition towers are used to change the phase position of conductors to balance the capacitance and inductance of three-phase transmission lines. Terminal towers are used at the terminal of the transmission line and are connected to a substation or a power plant. Crossing towers are used to cross obstacles such as rivers, valleys, railways, and highways;

[0003] During the welding process, when the transmission of the wire required for welding is blocked, there is an error between the transmission speed of the wire and the welding speed, resulting in the inability to carry out the welding work normally. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] An automatic welding equipment for iron accessories of electric power transmission towers, comprising:

[0006] A frame body, on both sides of which lifting cylinders are fixedly installed. A support plate is slidably installed inside the frame body, and the output ends of the lifting cylinders are fixedly connected to both ends of the bottom of the support plate;

[0007] A support mechanism, which is installed inside the frame body and is located below the support plate;

[0008] A clamping mechanism, which is installed on the top of the support mechanism and is symmetrically installed along the axial center position of the support mechanism;

[0009] A first motor is fixedly installed at the top of the support plate. The output end of the first motor penetrates through the support plate and extends to its bottom. And the output end of the first motor is fixedly installed with a support frame. A second motor is fixedly installed on the outer side of the support frame. The output end of the second motor penetrates through the support frame and extends to its interior. And the output end of the second motor is fixedly installed with a rotating cylinder. A support shaft is fixedly installed on the outer side of the support frame. On both sides of the top of the inner wall of the support frame, support blocks are fixedly installed. A rotating column is rotatably installed between the support blocks. The outer diameter of the rotating column gradually increases from the central position to both ends. Through the change of the outer diameter of the rotating column, it cooperates with the change of the through groove width of the side groove plate. The through groove of the side groove plate is used to limit the wire imported and exported between the rotating column and the rotating cylinder, so that the wire is concentrated in the central area and exported, making the process of importing the wire into the welding torch smoother. At the same time, by using the change of the outer diameter of the rotating column, when the wire is offset, the larger outer diameter on both sides restricts the deformation of the rubber cylinder, increases the contact pressure between the rubber cylinder and the wire, increases the friction force, provides greater power for the transmission of the wire, and cooperates with the side groove plate. When the wire is offset, it increases the transmission force, so that the wire is smoothly fed, avoiding the blockage of the wire transmission when the wire is offset, resulting in the inability to carry out welding. And a rubber cylinder is fixedly installed on the outer side of the rotating column. The bottom of the rubber cylinder is in close contact with the top of the rotating cylinder. A welding torch is fixedly installed at the bottom of the support frame. Side groove plates are fixedly installed on both sides of the inner wall of the support frame. The rotating cylinder is located between the side groove plates. A through groove is opened at the central position on the outer side of the side groove plate, and the width of the through groove gradually decreases from the central position to both sides. Through the change of the through groove width of the side groove plate, the wire in the import and export process is concentrated in the central area, reducing the bending angle of the wire imported into the welding torch, reducing the friction force between the wire and the welding torch, and making the import of the wire smoother.

[0010] Preferably, the support mechanism includes a sliding seat and a third motor. The third motor is fixedly installed on one side of the top of the frame body. And the output end of the third motor is fixedly installed with a screw rod through a coupling. On both sides of the bottom of the sliding seat, sliding blocks are fixedly installed. The sliding seat is slidably adapted to the top of the frame body through the sliding blocks. A screw cylinder is fixedly installed at the central position of the bottom of the sliding seat. The inner wall of the screw cylinder is threadedly connected to the outer side of the screw rod.

[0011] Preferably, a circular groove plate is fixedly installed at the center position of the top of the sliding seat. An outer circular groove is provided at the center position of the top of the circular groove plate, and an inner circular groove is provided at the center position of the outer circular groove. Guide grooves are symmetrically provided at the top of the circular groove plate. A tray is installed at the outer circular groove of the circular groove plate. The bottom of the tray fits with the position of the outer circular groove of the circular groove plate. A chassis is fixedly installed at the center position of the bottom of the tray. Spherical protrusions are evenly provided at the bottom of the chassis. Through the spherical protrusions at the bottom of the chassis, the contact area with the circular groove plate is reduced, the friction between the chassis and the circular groove plate is decreased. Cooperating with the clamping mechanism, during the positioning and fixing process, the resistance received when adjusting the material is reduced, and the material is more easily fixed and positioned. A convex block is fixedly installed at the top of the tray. The convex blocks are evenly installed along the center position of the tray. By the contact between the convex blocks at the top of the tray and the bottom of the tower foot, a gap is generated between the tower foot and the top plane of the tray, providing a path for the passage of air. During the welding process, the flowing air drives the heat between the tower foot and the tray, improving the cooling effect and preventing the temperature of the tray from being too high after welding, which may cause scalding when the material is put in again.

[0012] Preferably, the clamping mechanism includes a clamping cylinder. The clamping cylinder is fixedly installed at the corner of the top of the sliding seat. The output end of the clamping cylinder is fixedly connected with a connecting block. The connecting block is slidably adapted to the guide groove of the circular groove plate. Side blocks are fixedly installed on both sides of the connecting block. The bottom of the side block fits with the top of the circular groove plate. An inclined groove plate is fixedly installed outside the connecting block. One end of the inclined groove plate away from the connecting block inclines outward, and a plate groove is provided on the outside of the inclined groove plate.

[0013] Preferably, an inner sliding beam is slidably installed at the plate groove of the inclined groove plate. A cushion ring is fixedly installed between the inner sliding beam and the connecting block. By the cooperation of the cushion ring and the rubber pad, during the clamping process, through the restriction of the inclined groove plate on the clamping block and the deformation of the cushion ring and the rubber pad, after the clamping block clamps the material, it is located at the center position between the inclined groove plates, continuously clamping and fixing the material while realizing the positioning of the material. The cushion ring is made of elastic material. A clamping block is fixedly installed at the center position of the outside of the inner sliding beam. Rubber pads are fixedly installed on both sides of the clamping block. One end of the rubber pad away from the clamping block is closely attached to the opposite surface of the inclined groove plate.

[0014] The present invention provides an automatic welding device for iron accessories of a power transmission tower. It has the following beneficial effects:

[0015] 1. The automatic welding equipment for iron accessories of the power transmission tower coordinates the change in the outer diameter of the rotating column with the change in the width of the through slot of the side groove plate. By using the through slot of the side groove plate to restrict the wire introduced and exported between the rotating column and the rotating cylinder, the wire is concentrated and exported in the central area, making the process of introducing the wire into the welding torch smoother. At the same time, by using the change in the outer diameter of the rotating column, when the wire is offset, the larger outer diameter on both sides restricts the deformation of the rubber cylinder, increasing the contact pressure between the rubber cylinder and the wire, increasing the friction force, providing greater power for the transmission of the wire, and cooperating with the side groove plate. When the wire is offset, the transmission force is increased, enabling the wire to be smoothly fed and preventing the transmission of the wire from being blocked when the wire is offset, which may lead to the inability to perform welding.

[0016] 2. The automatic welding equipment for iron accessories of the power transmission tower makes the wire concentrated in the central area during the import and export processes through the change in the width of the through slot of the side groove plate, reducing the bending angle of the wire when it is introduced into the welding torch, reducing the friction force between the wire and the welding torch, and making the introduction of the wire smoother.

[0017] 3. The automatic welding equipment for iron accessories of the power transmission tower reduces the contact area with the circular groove plate through the spherical protrusions at the bottom of the chassis, reducing the friction force between the chassis and the circular groove plate. Cooperating with the clamping mechanism, during the positioning and fixing process, the resistance encountered when adjusting the material is reduced, making it easier to fix and position the material.

[0018] 4. The automatic welding equipment for iron accessories of the power transmission tower makes the convex block at the top of the tray contact the bottom of the tower foot, creating a gap between the tower foot and the top plane of the tray, providing a path for the passage of air. During the welding process, the flow of air drives the heat between the tower foot and the tray, improving the cooling effect and preventing the temperature of the tray from being too high after welding, which may cause burns when the material is placed again.

[0019] 5. The automatic welding equipment for iron accessories of the power transmission tower restricts the clamp block through the inclined groove plate and deforms the spacer ring and rubber pad. After the clamp block clamps the material, it is located at the central position between the inclined groove plates, continuing to clamp and fix the material while achieving the positioning of the material.

The third motor 21 is fixedly installed on one side of the top of the frame body 1, and the output end of the third motor 21 is fixedly installed with a screw rod 23 through a coupling. Sliders 27 are fixedly installed on both sides of the bottom of the sliding seat 22. By starting the third motor 21, the third motor 21 drives the screw rod 23 to rotate. By using the threaded connection between the screw rod 23 and the screw barrel 28, the sliding seat 22 is driven to move, so that the sliding seat 22 drives the clamping mechanism 3 and the circular groove plate 24 to reach a position convenient for placing. The sliding seat 22 is slidably adapted to the top of the frame body 1 through the sliders 27. A screw barrel 28 is fixedly installed at the central position of the bottom of the sliding seat 22, and the inner wall of the screw barrel 28 is threadedly connected to the outer side of the screw rod 23.

[0039] At the central position on the top of the sliding seat 22, a circular groove plate 24 is fixedly installed. At the central position on the top of the circular groove plate 24, an outer circular groove is provided, and an inner circular groove is provided at the central position of the outer circular groove.

The bottom of the tray 25 is in fit with the position of the outer circular groove of the circular groove plate 24. Workers place the tower foot and iron accessories after spot welding on the top of the tray 25. Through the convex block 29 on the top of the tray 25, it contacts the bottom of the tower foot. After placing, by means of the spherical protrusion at the bottom of the chassis 26 contacting the circular groove plate 24, the friction with the circular groove plate 24 is reduced. Subsequently, through the cooperation of the clamping mechanism 3 and the tray 25, the materials are fixed. And at the central position on the bottom of the tray 25, a chassis 26 is fixedly installed. The bottom of the chassis 26 is evenly provided with spherical protrusions.

[0040] For the third embodiment, on the basis of the first and second embodiments, please refer to Figure 10 As shown, the clamping mechanism 3 includes a clamping cylinder 31. The clamping cylinder 31 is fixedly installed at the corner of the top of the sliding seat 22. And the output end of the clamping cylinder 31 is fixedly connected with a connecting block 34. The connecting block 34 is slidably adapted to the guide groove of the circular groove plate 24. Side blocks 32 are fixedly installed on both sides of the connecting block 34. By driving the connecting block 34 to slide at the guide groove of the circular groove plate 24 through the clamping cylinder 31, the connecting blocks 34 approach each other, contacting the corner positions of the materials. At the same time, during the process of gradually approaching, the corner of the tower foot is contacted through the clamping block 37. The bottom of the side block 32 is in fit with the top of the circular groove plate 24. An inclined groove plate 33 is fixedly installed on the outside of the connecting block 34.

A cushion ring 35 is fixedly installed between the inner sliding beam 36 and the connecting block 34. The cushion ring 35 is made of an elastic material. During the process of continuously approaching and clamping, the pressure is transmitted to the cushion ring 35 through the inner sliding beam 36. By utilizing the elastic deformation characteristics of the cushion ring 35, the cushion ring 35 deforms under the clamping pressure, enabling the clamping block 37 and the inner sliding beam 36 to slide inward between the inclined groove plates 33. During the sliding process, through the cooperation between the clamping mechanisms 3, during the process of gradually clamping and fixing, in cooperation with the sliding between the chassis 26 and the circular groove plate 24, while fixing the tower foot, the tower foot is positioned at the central position. At the central position on the outside of the inner sliding beam 36, a clamping block 37 is fixedly installed. Rubber pads 38 are fixedly installed on both sides of the clamping block 37. One end of the rubber pad 38 away from the clamping block 37 is in close fit with the opposite surface of the inclined groove plate 33.

[0042] During use, the worker places the tower foot and the rib plate iron attachment after spot welding pre-fixation into the support mechanism 2. Subsequently, the clamping mechanism 3 and the support mechanism 2 cooperate to fix the material at the central position on the top of the support mechanism 2. Then, when the support mechanism 2 drives the material to the welding position for welding. During welding, the welding wire coil is placed into the support shaft 11, and the second motor 8 drives the wire into the welding torch 9, and power-on welding is performed at the welding position. At the same time, the first motor 5 drives the support frame 7 to rotate, causing the welding torch 9 to rotate, and cooperating with the support mechanism 2 for automated welding.

[0043] During the process of feeding the wire, first, one end of the wire passes through the side groove plate 10 and exits from the side groove plate 10 on the other side. When passing through, the wire passes between the rotating cylinder 12 and the rubber cylinder 14. Finally, the wire penetrates into the welding torch 9. During welding, the second motor 8 drives the rotating cylinder 12 to rotate. During the rotation process, through the friction between the rotating cylinder 12 and the rubber cylinder 14, and in cooperation with the friction between the rubber cylinder 14 and the wire, the wire is driven to move, causing the wire coil to rotate and unwind under the restriction of the support shaft 11. At the same time, during the movement process, through the cooperation of the rotating column 15 and the through groove of the side groove plate 10, and by using the change in the width of the through groove of the side groove plate 10, when the wire groove is guided into the area between the rubber cylinder 14 and the rotating cylinder 12, the wire is brought closer to the central area between the rubber cylinder 14 and the rotating cylinder 12.

[0044] When placing the welding material, by starting the third motor 21, the third motor 21 drives the stud 23 to rotate. Utilizing the threaded connection between the stud 23 and the screw barrel 28, the sliding seat 22 is driven to move, causing the sliding seat 22 to drive the clamping mechanism 3 and the circular groove plate 24 to reach a position convenient for placement. Subsequently, the worker places the tower foot and the iron attachment after spot welding fixation on the top of the tray 25. The convex block 29 on the top of the tray 25 contacts the bottom of the tower foot. After placement, the spherical protrusion at the bottom of the chassis 26 contacts the circular groove plate 24 to reduce the friction with the circular groove plate 24. Subsequently, the clamping mechanism 3 and the tray 25 cooperate to fix the material.

[0045] In the clamping mechanism 3, the clamping cylinder 31 drives the connecting block 34 to slide in the guide groove of the circular groove plate 24, causing the connecting blocks 34 to approach each other and contact the corner positions of the material. At the same time, during the gradual approach process, the clamping block 37 contacts the corner of the tower foot. And during the continuous approach and clamping process, the pressure is transmitted to the cushion ring 35 through the inner sliding beam 36. Utilizing the elastic deformation characteristics of the cushion ring 35, the cushion ring 35 deforms under the clamping pressure, causing the clamping block 37 and the inner sliding beam 36 to slide inward between the inclined groove plates 33. During the sliding process, through the cooperation between the clamping mechanisms 3, during the process of gradually clamping and fixing, in cooperation with the sliding between the chassis 26 and the circular groove plate 24, while fixing the tower foot, the tower foot is positioned at the central position.
