Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to a transmission tower welding device. Background Art

[0002] Transmission towers are structures used to support and suspend transmission lines in power systems. They are usually made of steel or concrete and have sufficient mechanical strength and stability to withstand the weight of accessories such as conductors, ground wires, insulators and hardware, as well as external forces such as wind loads, ice loads, and line break tension. In the design and manufacture of transmission towers, beams are one of the important load-bearing structures. They are usually used to connect different parts of the tower to increase the rigidity and stability of the overall structure. By welding two short beams into a long beam, a continuous bearing surface can be provided, the tower's anti-bending ability can be enhanced, and it helps to disperse and transfer the load.

[0003] In the actual welding process, you first need to use limiting components to fix the two short beams respectively, and then move the two limiting components towards each other until one side of the two short beams abuts. Next, move the welding head downward to make it close to the abutment position of the two short beams, and weld the two short beams together through the welding head. After welding is completed, the welding head will move upward back to the initial position. After the two limiting components release the clamping of the short beams, the two limiting components will move to both sides. At this time, the long beam will remain in the middle position. Some factories use robots and other equipment to weld the completed beams after the limiting components release the clamping of the beams. The beam can be transferred, but the cost of the robot is high. Therefore, many factories still use manual handling to transfer the beam. Usually a placement plate is set in the middle position, and the welded beam will be placed on the placement plate. However, the workers may not complete the transportation of the beam as soon as the welding is completed. The workers' temporary handling of other things will cause the beam to be placed on the placement plate for a period of time. The processing environment in the workshop is relatively complex. The operation of large machinery or the falling of heavy objects will cause shaking, which will cause the beam to not be placed so stably on the placement plate, and there is a possibility of the beam shifting or falling.

The rotation of the screw rod 3 will drive the moving cylinder 24 and the storage frames 7 on both sides to move towards each other. When one side of the two short beams abuts against each other, the screw rod 3 is stopped, and the lifting plate 5 and the welding gun 6 are moved downward along the fixed plate 4. The welding gun 6 can weld the two short beams into a long beam, and then the lifting plate 5 is moved upward. At the same time, the storage frames 7 approach each other until one side of the short beams abuts against each other. At this time, the support plate 8 is located in the notch 71, and the top of the support plate 8 abuts against the bottom of the short beam. When the two storage frames 7 move away from each other after welding, the support plate 8 can provide a certain support for the long beam, which is convenient for the operator to remove the long beam. In the process of the storage frames 7 moving away from each other, the support assembly 9 can further strengthen the support and limiting effect of the support plate 8 on the long beam to ensure the stability of the long beam. Both the vertical plate 2 and the bottom plate 1 provide support.

[0035] See also Figure 8-Figure 9 As shown, in this embodiment, preferably, the support assembly 9 includes an L-shaped plate 91, the L-shaped plate 91 is slidably connected to the transverse groove 81, and connecting plates 92 are axially symmetrically fixedly arranged on both sides of the bottom of the L-shaped plate 91, and a cross bar 93 is movably connected to one side of the connecting plate 92, and a deflection rod 94 is movably sleeved on the outer side of the cross bar 93, and a sliding block 95 is movably connected to the other end of the deflection rod 94, and a square block 96 is movably arranged on the outer side of the sliding block 95, and the square block 96 is fixedly connected to the inner wall of the transverse groove 81; after the storage frames 7 move away from each other until the storage frames 7 After the contact with the cross beam is released, the sliding block 95 is moved along the square block 96 toward the outside of the cross groove 81. The movement of the sliding block 95 will drive the deflection rod 94, the cross rod 93, the connecting plate 92 and the L-shaped plate 91 to move toward the outside of the cross groove 81. The top of the L-shaped plate 91 slides and fits with the inner wall of the cross groove 81. When a part of the L-shaped plate 91 moves to the outside of the cross groove 81, the deflection rod 94 is rotated to drive the cross rod 93, the connecting plate 92 and the L-shaped plate 91 to move upward. The L-shaped plate 91 moves to both sides of the cross beam, thereby increasing the cross-sectional area of ​​the support plate 8, and providing better support for the long cross beam.

[0036] See also Figure 8-Figure 10 As shown, in this embodiment, preferably, the end of the cross bar 93 away from the connecting plate 92 is movably connected to a movable column 10, and positioning plates 11 are axially symmetrically fixedly arranged on both sides of the transverse groove 81. A limiting groove 111 is provided on the positioning plate 11, and the limiting groove 111 consists of a straight groove and a vertical groove. The movable column 10 is slidably connected to the limiting groove 111, and a movable plate 12 is fixedly connected between the two sliding blocks 95; the movable plate 12 is moved in a direction away from each other, and the movement of the movable plate 12 will drive the two sliding blocks 95 to move along the square block 96 to the outside of the transverse groove 81 The movement of the sliding block 95 will drive the deflection rod 94, the cross bar 93, the connecting plate 92 and the L-shaped plate 91 to move toward the outside of the cross groove 81. The movement of the cross bar 93 will drive the moving column 10 to move along the limiting groove 111 opened on the positioning plate 11. The moving column 10 first moves along the straight groove section of the limiting groove 111. When a part of the L-shaped plate 91 moves to the outside of the cross groove 81, the moving column 10 moves to the vertical groove section of the limiting groove 111. At this time, continuing to move the movable plate 12 and the sliding block 95 will drive the deflection rod 94 to rotate, thereby realizing the upward movement of the L-shaped plate 91, which can provide support for the long beam.

[0037] See also Figure 8-Figure 11As shown, in this embodiment, preferably, the positioning plate 11 is located above the straight groove section of the limiting groove 111 and is provided with a moving groove 112. The moving groove 112 is composed of a straight groove and an inclined groove. A limiting rod 13 is slidably arranged in the moving groove 112, and the limiting rod 13 is slidably connected to one side of the L-shaped plate 91. One end of the limiting rod 13 is fixedly connected to a support plate 14, and the support plate 14 is slidably connected to the top of the L-shaped plate 91 and a first spring 15 is fixedly connected between the L-shaped plate 91; during the process of the movable plates 12 moving away from each other, the L-shaped plate 91 will be driven to move toward the outside of the transverse groove 81, and the movement of the L-shaped plate 91 will drive the limiting rod 13 to move along the straight groove section of the moving groove 112 first, and the support plate 14 on the L-shaped plate 91 will move to a part of the distance outside the transverse groove 81. Because the width of the crossbeam is greater than the width of the support plate 8, the support plate 14 has to move to a distance outside, and then the movable column 10 moves to the limiting groove 11 1, the upward movement of the L-shaped plate 91 will drive the limiting rod 13 to move along the oblique groove section of the moving groove 112. At this time, the support plate 14 will move upward so that the horizontal plate set on the support plate 14 will abut against the bottom of the cross beam. The vertical plate of the support plate 14 is still a short distance away from the side of the cross beam. Because the storage frame 7 will generate friction with the cross beam during the process of moving away from each other, although the support plate 8 supports the cross beam at the bottom of the cross beam, the cross beam may be slightly tilted under the action of friction and may not be placed flat on the support plate 8. The support plate 14 moves outward for a longer distance to avoid the vertical plate from colliding with the cross beam during the upward movement of the support plate 14. With the cooperation of the limiting rod 13 and the oblique groove section of the moving groove 112, the support plate 14 can be moved in the direction close to the cross beam during the upward movement, shortening the distance from the side of the cross beam, and enhancing the protective effect of the support plate 14 on the cross beam.

The heights of the two second gears 19 and the second rack 20 are designed to be different heights to avoid collision between the two second racks 20 when the storage frames 7 approach each other. After welding is completed, the two storage frames 7 move away from each other. When the notch 71 is no longer in contact with the support plate 8, the second rack 20 will drive the second gear 19 to rotate in the opposite direction, so that the two support plates 14 can move to the outside of the transverse groove 81, which can protect the crossbeam on the support plate 8.

After limiting, The storage frame 7 will continue to move so that the third gear 28 is meshed with the fourth rack 222, and the third gear 28 rotates counterclockwise, and the moving rack 211 will not move, and the short beam is still limited and fixed. After one side of the short beam abuts against each other, the lifting plate 5 and the welding gun 6 are moved downward, and the welding gun 6 can weld the short beam. The downward movement of the lifting plate 5 will drive the rotating plate 223 to rotate, thereby driving the fourth rack 222 to move. During the movement of the fourth rack 222 away from the welding gun 6, the third gear 28 will be driven to rotate counterclockwise, and the clamping of the moving rack 211 on the short beam will not be released. When welding is completed, the upward movement of the lifting plate 5 and the welding gun 6 will drive the rotating plate 223 to rotate, thereby driving the fourth rack 222 to move closer to the fixed frame 221 The welding gun 6 moves in the direction of rotation, and the movement in this direction will drive the third gear 28 to rotate clockwise, so that the movable rack 211 releases the limit on the cross beam, and then the reverse rotation of the screw rod 3 will drive the two storage frames 7 to move away from each other. When the notch 71 is released from contact with the support plate 8, the second rack 20 will drive the second gear 19 to rotate, and the rotation of the second gear 19 will drive the two movable plates 12 to move away from each other. During the process of the movable plates 12 moving away from each other, the L-shaped plate 91 will be driven to move toward the outside of the transverse groove 81. The movement of the L-shaped plate 91 will drive the limiting rod 13 to move along the straight groove section of the movable groove 112 first, and the support plate 14 on the L-shaped plate 91 will move to a part of the distance outside the transverse groove 81. Because the width of the cross beam is greater than the width of the support plate 8, the support plate 14 has to move The L-shaped plate 91 moves upward to drive the limiting rod 13 to move along the oblique groove section of the moving groove 112. At this time, the support plate 14 moves upward to make the horizontal plate arranged on the support plate 14 contact with the bottom of the cross beam. The vertical plate of the support plate 14 is still a short distance away from the side of the cross beam. Because the storage frame 7 will generate friction with the cross beam in the process of moving away from each other, although the support plate 8 supports the cross beam at the bottom of the cross beam, the cross beam may be slightly tilted under the action of friction and may not be placed flat on the support plate 8. The support plate 14 moves outward for a longer distance to avoid the vertical plate from colliding with the cross beam during the upward movement of the support plate 14.With the cooperation of the limiting rod 13 and the inclined groove section of the moving groove 112, the support plate 14 can move toward the direction close to the beam during the upward movement, shortening the distance from the side of the beam, and enhancing the protective effect of the support plate 14 on the beam.
