Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate flipping technology, and in particular to a flipping device for steel plate welding. Background Technology
[0002] In the process of steel plate welding, in order to ensure the integrity of the weld and the welding quality, it is usually necessary to flip the steel plate for welding. However, due to the large volume and heavy weight of the steel plate, manual flipping is not only inefficient but also poses a high safety risk. Therefore, in the actual processing, it is often necessary to use a flipping device to assist in the rotation and positioning of the steel plate, thereby facilitating subsequent welding operations.
[0003] However, in the existing technology, many flipping devices fail to effectively set up special limiting mechanisms during the flipping process, which leads to the risk of the steel plate shaking, shifting or even dislodging during the flipping operation. Since the steel plate is large and heavy, once it moves or slips, it will not only damage the workpiece itself, but may also cause safety hazards to the equipment or operators. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a flipping device for steel plate welding, so as to solve the problem that the failure to effectively set a special limiting mechanism leads to the risk of swaying, displacement or even dislocation of the steel plate during flipping operation, which poses a safety hazard to the equipment or operators.
[0005] To achieve the above objectives, this utility model provides a flipping device for steel plate welding, comprising a support base, a first base fixedly connected to the top of the support base, two sliding rods fixedly connected between the side wall of the first base and the top of the support base, a second base slidably connected between the outer walls of the two sliding rods, a first electric telescopic rod provided between the two sides of the first base and the second base, a flipping panel rotatably connected to the top of the first base and the second base, a second electric telescopic rod rotatably connected between the flipping panels located on the first base and the second base, and a limiting mechanism provided on the side wall of the flipping panel for limiting the steel plate flipped at the top of the flipping panel.
[0006] Preferably, the limiting mechanism includes a movable plate slidably connected between the top two sides of the flip panel. Multiple equidistantly distributed flipping blocks are fixedly connected to the side wall of the movable plate. Grooved plates are fixedly connected to both top sides of the flip panel. A toothed plate is slidably connected inside the grooved plate. A fixed plate is fixedly connected to the top of the toothed plate. Two springs are fixedly connected to the side wall of the fixed plate. A clamping plate is fixedly connected to one end of each spring. The clamping plate is slidably connected to the top of the toothed plate. A gear is rotatably connected to the inner wall of the grooved plate. A fixing ring is fixedly connected to the inner wall of the grooved plate near the outer periphery of the gear. A torsion spring is fixedly connected to the inner wall of the fixing ring. One end of the torsion spring is fixedly connected to the shaft of the gear. A steel wire rope is fixedly connected to the outer wall of the gear shaft. One end of the steel wire rope is fixedly connected to the side wall of the movable plate.
[0007] Preferably, guide wheels for guiding the wire rope are rotatably connected to the side walls of the flip panel near the groove plate on both sides.
[0008] Preferably, the tops of both the first base and the second base are fixedly connected with cushioning rubber pads for buffering the descent of the flip panel.
[0009] Preferably, the top of the clamping plate is arc-shaped.

[0011] The beneficial effects of this utility model are:
[0012] This steel plate welding flipping device uses a movable plate on the side of the flipping panel. When the steel plate slides, the movable plate moves, which in turn pulls a gear to rotate via a wire rope. The gear drives a toothed plate to slide towards the steel plate.

[0023] like Figures 1 to 5As shown, a steel plate welding flipping device includes a support base 1, a first base 2 fixedly connected to the top of the support base 1, two sliding rods 3 fixedly connected between the side wall of the first base 2 and the top of the support base 1, a second base 4 slidably connected between the outer walls of the two sliding rods 3, a first electric telescopic rod 5 provided between the two sides of the first base 2 and the second base 4, a flipping panel 6 rotatably connected to the top of the first base 2 and the second base 4, a second electric telescopic rod 7 rotatably connected between the flipping panels 6 located on the first base 2 and the second base 4, and a limiting mechanism provided on the side wall of the flipping panel 6 for limiting the steel plate flipped at the top of the flipping panel 6.
[0024] Further, see attached document. Figures 1 to 5 As shown, the limiting mechanism includes a movable plate 8 slidably connected between the top two sides of the flip panel 6. Multiple evenly distributed flipping blocks 9 are fixedly connected to the side walls of the movable plate 8. Grooved plates 10 are fixedly connected to both top sides of the flip panel 6. Toothed plates 11 are slidably connected inside the grooved plates 10. A fixed plate 12 is fixedly connected to the top of the toothed plates 11. Two springs 13 are fixedly connected to the side walls of the fixed plate 12. A clamping plate 14 is fixedly connected to one end of each spring 13 and slidably connected to the top of the toothed plates 11. A gear 15 is rotatably connected to the inner wall of the groove plate 10. A fixing ring 16 is fixedly connected to the inner wall of the groove plate 10 near the outer periphery of the gear 15. A torsion spring 17 is fixedly connected to the inner wall of the fixing ring 16. One end of the torsion spring 17 is fixedly connected to the shaft of the gear 15. A steel wire rope 18 is fixedly connected to the outer wall of the shaft of the gear 15. One end of the steel wire rope 18 is fixedly connected to the side wall of the movable plate 8. Guide wheels 19 for guiding the steel wire rope 18 are rotatably connected to both sides of the flip panel 6 near the side wall of the groove plate 10.
[0025] In this embodiment, when it is necessary to flip the steel plate, the steel plate is first placed on the flip panel 6 on the top of the second base 4 and the first side is welded. After the welding is completed, the first electric telescopic rod 5 set on the second base 4 is activated, which drives the second base 4 to slide along the outer wall of the slide rod 3. After the second base 4 slides to a predetermined position away from the flip panel 6, the bottom of the flip panel 6 on the top of the first base 2 and the second electric telescopic rod 7 are activated to drive the flip panel 6 to rotate around the hinge point to a 90° vertical state.
[0026] Subsequently, the second electric telescopic rod 7, which is set on the top of the second base 4, is activated again, causing the flip panel 6 to rotate 90° in the horizontal direction. During the flipping process, the steel plate slides downward due to gravity and presses the moving plate 8 located on the side of the flip panel 6. After being pressed, the moving plate 8 slides along the guide structure and pulls the gear 15 to rotate through the connected steel wire rope 18.
[0027] When the gear 15 rotates, it drives its shaft to wrap around the torsion spring 17 and simultaneously drives the toothed plate 11 that meshes with it to slide towards the steel plate. This causes the clamping plate 14 on the toothed plate 11 to gradually contact and clamp the side wall of the steel plate. During the clamping process, the clamping plate 14 compresses the spring 13 on its back. The elastic force of the spring 13 enables the clamping plate 14 to achieve stable elastic clamping on both sides of the steel plate, thereby forming a limiting structure to prevent the steel plate from shifting position or slipping during the flipping process.
[0028] As the flipping continues, when the flip panel 6 on the second base 4 approaches the flip panel 6 on the first base 2, the steel plate supported on the second base 4 will press against the moving plate 8 on the side wall of the first base 2. Since the flipping blocks 9 on the two flip panels 6 are arranged in an alternating manner, when the steel plate presses the moving plate 8 at the top of the first base 2 to move downward, it will trigger the action of the clamping plate 14 in its upper limit mechanism to achieve the second clamping limit. The two limit mechanisms are staggered in height to ensure that the clamping action is completed in sequence and does not interfere with each other.
[0029] Finally, the second electric telescopic rod 7 between the first base 2 and the flip panel 6 on it is activated, driving the flip panel 6 to rotate in the opposite direction. During this rotation, the flipping block 9 on the side wall of the flip panel 6 will push the steel plate onto the flip panel 6 at the top of the first base 2, completing the overall flipping operation of the steel plate.
[0030] By setting a movable plate 8 on the side of the flip panel 6, the movable plate 8 moves when the steel plate slides, and then pulls the gear 15 to rotate through the wire rope 18. The gear 15 drives the toothed plate 11 to slide towards the steel plate. The clamping plate 14 on the toothed plate 11 presses the two sides of the steel plate under the elastic force of the spring 13, realizing automatic clamping and limiting of the steel plate. This limiting mechanism can provide bidirectional limiting protection throughout the flipping process, preventing the steel plate from shifting, shaking or falling due to gravity sliding. It is particularly suitable for the welding and flipping process of large and heavy steel plates, significantly improving the safety and stability of equipment operation and facilitating the continuous operation of subsequent welding operations.
[0031] Furthermore, referring to the attached drawings, the top of the first base 2 and the second base 4 are both fixedly connected with buffer rubber pads 20 for cushioning the descent of the flip panel 6. The buffer rubber pads 20 are designed so that when the flip panel 6 is rotated and comes into contact with the top of the first base 2 or the second base 4, it will contact the top of the buffer rubber pads 20, thereby reducing the impact force on the first base 2 or the second base 4 after the flip panel 6 has rotated and increasing the life of the equipment.
[0032] Further, see attached document. Figure 2 and Figure 3As shown, the top of the clamping plate 14 is arc-shaped. Due to the arc shape of the clamping plate 14, when the steel plate on the top flip panel 6 of the second base 4 rotates onto the top flip panel 6 of the first base 2, the steel plate will press against the moving plate 8, which will then slightly drive the clamping plate 14 in the limiting mechanism to move closer to the middle of the flip panel 6. Through the arc shape of the top of the clamping plate 14, the two sides of the steel plate can be pressed into the limiting mechanism on the top flip panel 6 of the first base 2, so that the plate can be limited throughout the flipping process and displacement can be avoided.
[0033] Further, see attached document. Figure 2 and Figure 3 As shown, the flipping blocks 9 on the side wall of the top flip panel 6 of the first base 2 and the second base 4 are staggered, which can ensure the stability of the steel plate when flipping, and also facilitate the flipping blocks 9 on the top flip panel 6 of the first base 2 to move the steel plate to its own side wall.
