Description

Technical Field

[0001] This utility model relates to the technical field of foot plate welding devices, and in particular to a flipping device for welding foot plates of power transmission towers. Background Technology

[0002] Transmission tower base plates are welded supports, and the welding process requires flipping the base plates to weld on both sides. Various tower base plate welding devices are disclosed in the prior art. For example, the tower base plate welding fixture proposed in Chinese Utility Model Patent Publication No. CN211136050U includes a platform, a base frame, and a mounting platform. The platform is equipped with positioning components for fixing the tower base plates. The mounting platform is hinged to the base frame, and the platform is rotatably mounted on the mounting platform. A motor is installed on the mounting platform to drive the platform's rotation. By rotating or tilting the platform, the position of the joint requiring welding reinforcement can be adjusted, simplifying the welding robot's path and eliminating the need for upper joint structures and corresponding drive devices on the welding robot. This simplifies worker operation and reduces costs.

[0003] However, the mounting platform of the aforementioned tower foot plate welding fixture can only be rotated 90 degrees, and cannot be rotated 180 degrees, which makes it inconvenient to efficiently weld the bottom surface of the transmission tower foot plate, thus having certain limitations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a power transmission tower footplate welding flipping device that can rotate the base plate of the power transmission tower from 0 degrees to 180 degrees, with few limitations and which is conducive to improving welding efficiency.

[0005] This utility model discloses a welding and flipping device for power transmission tower foot plates, comprising a base and a platform, with the platform mounted on the base; it also includes two outer frames, two inner frames, two upper sliding members, two push rods, two lower sliding members, and a drive mechanism. Mounting plates are provided at both ends of the platform, and two sliding tracks are provided on each of the two mounting plates, arranged vertically. The two outer frames are respectively arranged opposite each other on the inner sides of the two mounting plates of the platform. The middle parts of the two outer frames are respectively connected to the middle parts of the two inner frames via shafts. The outer and inner frames are arranged parallel to each other, and a foot plate clamping assembly is provided between the two inner frames. Upper sliding members are installed at one end of each of the two outer frames, and the two upper sliding members are slidably mounted in the two upper sliding tracks on the two mounting plates. The upper ends of the two push rods are rotatably connected to the two shafts, and the lower ends of the two push rods are installed with lower sliding members, and the two lower sliding members are slidably mounted in the two lower sliding tracks on the two mounting plates. The two lower sliding members and the two upper sliding members are arranged opposite each other. The drive mechanism is mounted on the base and is used to drive the two outer frames. The upper sliding member and two lower sliding members move relative to each other. During operation, the transmission tower foot plate is loaded onto the clamping assembly, and the welding equipment is used to weld the upper surface of the transmission tower foot plate. After the upper surface is welded, the drive mechanism drives the two upper sliding members to move from the front end to the rear end of the two upper slides. At the same time, the drive mechanism drives the two lower sliding members to move from the rear end to the front end of the two lower slides. As the two upper sliding members and two lower sliding members approach and meet, the two push rods gradually rise from the flat state, thereby pushing the two outer frames to the vertical state. As the two upper sliding members and two lower sliding members move away from each other after meeting, the two push rods gradually flatten in the opposite direction from the vertical state, thereby flattening the two outer frames to the horizontal state. At this time, the two outer frames and two inner frames are rotated 180 degrees. The welding equipment is then used to weld the lower surface of the transmission tower foot plate. Compared with the existing technology, this method can rotate the transmission tower foot plate from 0 degrees to 180 degrees, with fewer limitations and is conducive to improving welding efficiency.

[0006] Preferably, the drive mechanism includes a lower screw, a lower slider, an upper screw, an upper slider, two gears, and a motor. The lower screw is rotatably mounted on the mounting plate of the base. The lower slider is threadedly connected to the lower screw and to the lower slide piece. The upper screw is rotatably mounted on the mounting plate of the base. The upper slider is threadedly connected to the upper screw and to the lower slide piece. The pitch of the thread on the lower screw is greater than that on the upper screw. Gears are concentrically mounted on both the upper screw and the upper slider, and the two gears mesh. The motor is mounted on the base, and the output shaft of the motor is drivenly connected to the lower screw. The drive screw rotates, the slide groove drives a gear to rotate, and the two gears mesh to drive the upper screw to rotate synchronously. The threaded action of the lower screw and the lower slider causes the lower slider to move along the lower slide rail, while the threaded action of the upper screw and the upper slider causes the upper slider to move along the upper slide rail. Because the thread pitch of the lower screw is greater than that of the upper screw, the lower slider moves faster than the upper slider when the lower and upper screws rotate synchronously, allowing the lower and upper sliders to meet in the middle of the base, resulting in a good driving effect.

[0007] Preferably, it also includes two push cylinders and two positioning pins. The two push cylinders are respectively installed on the two outer frames, and the piston rod ends of the two push cylinders are each equipped with a positioning pin. The two positioning pins can be inserted into the two upper slides of the base respectively. When the two outer frames are flat, the piston rods of the two push cylinders extend synchronously, causing the two positioning pins to be inserted into the two upper slides of the base respectively, thereby providing auxiliary support to the ends of the two outer frames and improving stability.

[0008] Preferably, it also includes two longitudinal beams and multiple plate clamps. The two ends of the two longitudinal beams are respectively connected to two inner frames, and multiple plate clamps are movably installed on both longitudinal beams. The position of the multiple plate clamps can be adjusted along the two longitudinal beams. The multiple plate clamps are used to clamp the two ends of the transmission tower foot plates and can clamp transmission tower foot plates of different widths, which has good versatility.

[0009] Preferably, it also includes two sliding grooves and multiple locking screws. Sliding grooves are provided on both inner frames, and the two ends of the two longitudinal beams are slidably installed in the two sliding grooves respectively. Locking screws are installed at the ends of the two longitudinal beams, and the multiple locking screws are used to lock the ends of the two longitudinal beams onto the two inner frames. The position of the ends of the two longitudinal beams is adjusted along the two sliding grooves, and the multiple locking screws are tightened to lock the ends of the two longitudinal beams, so that the multiple plate clamps can clamp transmission tower foot plates of different lengths, improving versatility.

[0010] Preferably, the system also includes a turntable, multiple push cylinders, and multiple friction blocks. The turntable is mounted on a base, and the platform is mounted on the rotating end of the turntable. The multiple push cylinders are mounted on the platform and arranged around the turntable. Friction blocks are installed on the outputs of the multiple push cylinders. The turntable drives the platform to rotate horizontally, thereby adjusting the horizontal angle of the transmission tower footplate. After the platform is adjusted, the piston rods of the multiple push cylinders extend upward, causing the multiple push cylinders to press against the lower end face of the platform, thereby locking the platform and improving the welding efficiency of the transmission tower footplate and the stability of the platform.

[0011] Preferably, it also includes multiple strong magnetic blocks, with strong magnetic blocks installed on the upper surface of each of the multiple friction blocks; when the multiple friction blocks are pressed against the lower surface of the platform, the multiple strong magnetic blocks attract the platform, further improving the stability of the platform.

[0012] Compared with the prior art, the advantages of this utility model are: it can rotate the base plate of the power transmission tower from 0 degrees to 180 degrees, with fewer limitations, which is conducive to improving welding efficiency. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figures 1 to 5 As shown, a welding and flipping device for power transmission tower foot plates includes a base 1 and a platform 2, with the platform 2 mounted on the base 1. It also includes two outer frames 3, two inner frames 4, two upper sliding members 5, two push rods 6, two lower sliding members 7, and a drive mechanism. Mounting plates are provided at both ends of the platform 2, and two sliding tracks are provided on each of the two mounting plates, arranged vertically. The two outer frames 3 are respectively arranged opposite each other on the inner sides of the two mounting plates of the platform 2. The middle portions of the two outer frames 3 are connected to the middle portions of the two inner frames 4 via shafts. The outer frames 3 and inner frames 4 are arranged parallel to each other. A foot plate clamping assembly is provided between the two inner frames 4. Upper sliding members 5 are mounted on one end of each of the two outer frames 3, and the two upper sliding members 5 are slidably mounted on... The upper ends of two push rods 6 are rotatably connected to two shafts in the two upper slides on the two mounting plates. The lower ends of the two push rods 6 are each equipped with a sliding member 7. The two sliding members 7 are slidably installed in the two lower slides on the two mounting plates. The two sliding members 7 and the two upper sliding members 5 are arranged opposite to each other. The drive mechanism is installed on the base 1 and is used to drive the two upper sliding members 5 and the two sliding members 7 to move relative to each other. It also includes two push cylinders 14 and two positioning pins 15. The two push cylinders 14 are respectively installed on the two outer frames 3. The piston rod ends of the two push cylinders 14 are each equipped with a positioning pin 15. The two positioning pins 15 can be inserted into the two upper slides of the base 1 respectively.

[0023] During operation, the transmission tower footplates are loaded onto the clamping assembly. Welding equipment is used to weld the upper surfaces of the footplates. After welding, the drive mechanism moves two upper sliding members 5 from the front to the rear of the two upper tracks, while simultaneously moving two lower sliding members 7 from the rear to the front of the two lower tracks. As the two upper sliding members 5 and the two lower sliding members 7 approach and meet, the two push rods 6 gradually rise from a flat position, thus pushing the two outer frames 3 to a vertical position. As the two upper sliding parts 5 and the two lower sliding parts 7 move away from each other after they meet, the two push rods 6 gradually flatten in the opposite direction from the vertical position, thereby flattening the two outer frames 3 to a horizontal position. When the two outer frames 3 are flattened, the piston rods of the two push cylinders 14 extend synchronously, causing the two positioning pins 15 to be inserted into the two upper slides of the base 1, thereby providing auxiliary support to the ends of the two outer frames 3 and improving stability. At this time, the two outer frames 3 and the two inner frames 4 are rotated 180 degrees, and the welding equipment is used to weld the lower end face of the transmission tower foot plate. Example 2

[0024] like Figure 1 , Figure 2 , Figure 2 and Figure 6 As shown, based on Embodiment 1, the drive mechanism includes a lower screw 8, a lower slider 9, an upper screw 10, an upper slider 11, two gears 12, and a motor 13. The lower screw 8 is rotatably mounted on the mounting plate of the base 1. The lower slider 9 is threadedly connected to the lower screw 8 and is connected to the lower slide member 7. The upper screw 10 is rotatably mounted on the mounting plate of the base 1. The upper slider 11 is threadedly connected to the upper screw 10 and is connected to the lower slide member 7. The thread pitch of the lower screw 8 is greater than the thread pitch of the upper screw 10. Gears 12 are concentrically mounted on both the upper screw 10 and the upper slider 11, and the two gears 12 mesh. The motor 13 is mounted on the base 1, and the output shaft of the motor 13 is connected to the lower screw 8 for transmission.

[0025] Motor 13 drives the lower screw 8 to rotate, and slide 18 drives a gear 12 to rotate. The two gears 12 mesh to drive the upper screw 10 to rotate synchronously. The thread action between the lower screw 8 and the lower slider 9 drives the lower slide 7 to move along the lower slide. At the same time, the thread action between the upper screw 10 and the upper slider 11 drives the upper slide 5 to move along the upper slide. Since the thread pitch of the lower screw 8 is greater than the thread pitch of the upper screw 10, the lower screw 8 and the upper screw 10 rotate synchronously, so that the moving speed of the lower slider 9 is greater than the moving speed of the upper slider 11. This allows the lower slider 9 and the upper slider 11 to meet in the middle of the base 1, resulting in a good driving effect. Example 3

[0026] like Figure 4 , Figure 5 and Figure 7 As shown, based on Embodiment 1, it also includes two longitudinal beams 16 and multiple plate clamps 17. The two ends of the two longitudinal beams 16 are respectively connected to two inner frames 4, and multiple plate clamps 17 are movably installed on both longitudinal beams 16; it also includes two sliding grooves 18 and multiple locking screws 19. Sliding grooves 18 are provided on both inner frames 4, and the two ends of the two longitudinal beams 16 are respectively slidably installed in the two sliding grooves 18. Locking screws 19 are installed at the ends of both longitudinal beams 16, and multiple locking screws 19 are used to lock the ends of the two longitudinal beams 16 onto the two inner frames 4; it also includes a turntable 20, multiple push cylinders 21, and multiple friction blocks 22. The turntable 20 is installed on the base 1, the platform 2 is installed on the rotating end of the turntable 20, the multiple push cylinders 21 are installed on the platform 2, the multiple push cylinders 21 are arranged around the turntable 20, and friction blocks 22 are installed on the output of the multiple push cylinders 21; it also includes multiple strong magnetic blocks 23, and strong magnetic blocks 23 are installed on the upper surface of the multiple friction blocks 22.

[0027] Adjust the position of multiple plate clamps 17 along the two longitudinal beams 16. The multiple plate clamps 17 are used to clamp the two ends of the transmission tower foot plates and can clamp transmission tower foot plates of different widths. Adjust the position of the ends of the two longitudinal beams 16 along the two slide grooves 18. Tighten multiple locking screws 19 to lock the ends of the two longitudinal beams 16, so that the multiple plate clamps 17 can clamp transmission tower foot plates of different lengths, improving versatility. Turntable 20 drives platform 2 to rotate horizontally, thereby adjusting the horizontal angle of the transmission tower foot plates. After the platform 2 is adjusted, the piston rods of multiple push cylinders 21 extend upward, so that multiple push cylinders 21 press against the lower end face of platform 2. Multiple strong magnetic blocks 23 attract platform 2, improving the stability of platform 2.

[0028] like Figures 1 to 7As shown, this utility model discloses a welding and flipping device for power transmission tower foot plates. During operation, the power transmission tower foot plates are first loaded onto multiple plate clamps 17. The turntable 20 adjusts the horizontal angle of the platform 2. The welding equipment is then used to weld the upper surface of the power transmission tower foot plates. After the upper surface welding is completed, the drive mechanism drives two upper sliding members 5 to move from the front end to the rear end of two upper sliding tracks. Simultaneously, the drive mechanism drives two lower sliding members 7 to move from the rear end to the front end of two lower sliding tracks. As the two upper sliding members 5 and the two lower sliding members 7 approach and meet, two push rods 6 move from the release... The two outer frames 3 are gradually raised from their flat state, thus pushing them to a vertical position. As the two upper sliding parts 5 and the two lower sliding parts 7 meet and move away from each other, the two push rods 6 gradually move from the vertical state to the horizontal state, thus leveling the two outer frames 3. Then, when the two outer frames 3 are level, the piston rods of the two push cylinders 14 extend synchronously, causing the two positioning pins 15 to be inserted into the two upper sliding tracks of the base 1, thus providing auxiliary support for the ends of the two outer frames 3. At this time, the two outer frames 3 and the two inner frames 4 are rotated 180 degrees. Finally, the welding equipment is used to weld the lower end face of the transmission tower foot plate.

[0029] The main functions achieved by this utility model are:

[0030] 1. It can rotate the base plates of power transmission towers from 0 degrees to 180 degrees with few limitations, which helps to improve welding efficiency;

[0031] 2. It can clamp transmission tower foot plates of different sizes, and has good versatility;
