Description

Technical Field

[0001] This utility model relates to the field of I-beam welding technology, and more specifically, to a flipping device for welding I-beam components. Background Technology

[0002] In the welding production process of I-beam components, double-sided welding of the flanges and webs is required. After completing the welding on one side, the large I-beam component must be rotated 180° to allow welding of the other flange. Traditional methods mainly rely on cranes and manual operation for rotation, which is not only inefficient and poses a significant safety risk, but also makes it difficult to control the rotation accuracy, which can easily damage the component or weld.

[0003] While some existing specialized turning equipment can replace manual labor, they generally suffer from problems such as cumbersome operation procedures, insufficient clamping stability, or poor adaptability. Large I-beams are prone to swaying and shifting during turning, requiring repeated adjustments to positioning, which affects efficiency. At the same time, existing clamping devices are often complex in structure, time-consuming to clamp, and difficult to ensure the stability of the components during lifting and turning, increasing the difficulty of operation and safety risks. Therefore, in order to address the above technical problems, a turning device for welding I-beam components is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide a flipping device for welding I-beam components. The device uses a winch to control the lifting and lowering of the symmetrical mounting base by pulling the steel cable. The movable L-plate slides along the screw to achieve adaptive clamping. By utilizing the weight of the I-beam combined with the edge abutment of the double L-plates, a 180° smooth flipping can be completed quickly and synchronously by the steel cable, which significantly simplifies the operation process of welding large components.

[0005] This utility model is achieved through the following technical solution: A flipping device for welding I-beam components includes a base plate and a mounting base. A vertical plate is fixedly connected to the upper side of the base plate. Two sets of symmetrically arranged winches are fixedly connected to the upper side of the vertical plate. Steel cables are wound around the outside of the winches. The ends of the steel cables pass through the top of the vertical plate and are fixedly connected to the outside of the mounting base. A fixed L-plate is fixedly connected to the inner side of the mounting base. A movable L-plate is slidably connected to the inner side of the mounting base, and the movable L-plate and the fixed L-plate are symmetrically arranged. A clamping mechanism is installed on the outside of the mounting base.

[0006] Preferably, a placement seat is fixedly connected to the upper side of the base plate.

[0007] Preferably, a guide cylinder is fixedly connected to the bottom of the upright plate, and a steel cable passes through the inside of the guide cylinder.

[0008] Preferably, a fixing block is fixedly connected to the top of the mounting base, and the steel cable is fixedly connected to the outside of the fixing block.

[0009] Preferably, the mounting base has a slot on its inner side, and a slider is slidably connected to the inner side of the slot.

[0010] Preferably, the slider is externally fixedly connected to a connecting block, and the movable L-plate is fixedly connected to the connecting block.

The drive motor is fixedly connected to the outside of the mounting base, the lead screw is fixedly connected to one side of the output shaft of the drive motor, and the slider is threadedly connected to the outside of the lead screw.

[0012] The technical solution of this utility model has at least the following beneficial effects: This utility model proposes a turning device for welding I-beam components. It uses a winch in conjunction with steel cable traction to achieve smooth lifting and lowering of the I-beam. Through the symmetrically arranged L-shaped clamps and screw transmission structure, it can quickly adapt to the clamping requirements of I-beams of different sizes, ensuring stability during the turning process. It can quickly complete a 180° turn, avoiding the cumbersome process of repeated adjustments in traditional hoisting methods, effectively reducing labor intensity and safety risks. The design of the L-shaped clamps ensures uniform force on the edges of the I-beam, preventing deformation or damage. At the same time, the synchronous control of the winch makes the turning action more stable and reliable, significantly improving the efficiency and quality of welding operations.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-7 This utility model proposes a turning device for welding I-beam components, including a base plate 1 and a mounting base 7. The base plate 1 serves as the basic load-bearing component of the entire device, providing a stable mounting platform for other components. A vertical plate 3 is fixedly connected to the upper side of the base plate 1, serving as a vertical support structure to support the movement of the winch 4 and guide cable 5. Two sets of symmetrically arranged winches 4 are fixedly connected to the upper side of the vertical plate 3. The winches 4 serve as a power source for winding and unwinding the cable 5 to control the lifting and lowering of the mounting base 7. The cable 5 is wound around the outside of the winch 4, and the cable 5 serves as a traction component connecting the winch 4. The force is transmitted through the mounting base 7. The end of the steel cable 5 passes through the top of the vertical plate 3 and is fixedly connected to the outside of the mounting base 7. The mounting base 7 serves as the mounting base for the main clamping components. A fixed L-plate 9 is fixedly connected to the inner side of the mounting base 7. The fixed L-plate 9 serves as a fixed clamping surface to cooperate with the movable L-plate 13 to clamp the I-beam. The movable L-plate 13 is slidably connected to the inner side of the mounting base 7. The movable L-plate 13 serves as an adjustable clamping surface to adapt to the clamping requirements of I-beams of different sizes. The movable L-plate 13 and the fixed L-plate 9 are arranged symmetrically. A clamping mechanism is installed on the outside of the mounting base 7.

[0016] A placement seat 2 is fixedly connected to the upper side of the base plate 1. The placement seat 2 serves as a temporary support platform for the I-beam, facilitating clamping and positioning.

[0017] A guide cylinder 6 is fixedly connected to the bottom of the upright plate 3. The guide cylinder 6 serves as a guide component for the steel cable 5 to ensure the stability of the movement trajectory of the steel cable 5, and the steel cable 5 passes through the inner side of the guide cylinder 6.

[0018] The top of the mounting base 7 is fixedly connected to a fixing block 8. The fixing block 8 serves as the fixed connection point for the steel cable 5 to ensure the effective transmission of traction force, and the steel cable 5 is fixedly connected to the outside of the fixing block 8.

[0019] The mounting base 7 has a slot 10 on its inner side. The slot 10 serves as the movement track of the slider 11, which restricts its movement direction. The slider 11 is slidably connected to the inner side of the slot 10. The slider 11 serves as the driving connector of the movable L plate 13 to realize the transmission of clamping action.

[0020] The slider 11 is externally fixedly connected to a connecting block 12. The connecting block 12 serves as a connecting bridge between the movable L-plate 13 and the slider 11 to ensure synchronous movement, and the movable L-plate 13 and the connecting block 12 are fixedly connected.

[0021] The clamping mechanism includes a drive motor 14 and a lead screw 15. The drive motor 14 provides rotational power as the power source for the clamping action. The drive motor 14 is fixedly connected to the outside of the mounting base 7. The lead screw 15 is a motion conversion component that converts rotational motion into linear motion. The lead screw 15 is fixedly connected to one side of the output shaft of the drive motor 14, and the slider 11 is threadedly connected to the outside of the lead screw 15.

[0022] The working principle of a flipping device for welding I-beam components based on an embodiment is as follows: After welding one side flange of the I-beam to the web plate is completed, the flange with the welded part is first placed horizontally on the placement seat 2 on the base plate 1. A set of winches 4 is started to release the steel cable 5, so that the mounting seat 7 moves to the end of the flange. At this time, the drive motor 14 drives the lead screw 15 to rotate. Since the slider 11 is threadedly engaged with the lead screw 15 and is limited by the slot 10, it pushes the movable L plate 13 to move towards the fixed L plate 9, and the flange edge is tightly clamped by the L-shaped structure.

[0023] After clamping, winch 4 winds up steel cable 5, which, through guide cylinder 6, pulls mounting base 7 to lift the I-beam, causing it to tilt. The operator then adjusts the web position to place it on placement base 2, simultaneously releasing steel cable 5 from the other winch 4, moving the symmetrically positioned mounting base 7 to the opposite flange of the I-beam, and repeating the clamping process. Finally, both sets of winches 4 simultaneously wind up steel cable 5, achieving a 180° rotation of the I-beam under the traction of fixing block 8. This process, through the coordinated action of steel cable 5 and L-plate clamping mechanism, enables rapid reversal of the welding surface of the large I-beam, significantly improving welding efficiency. During the rotation, guide cylinder 6 ensures the stability of the steel cable 5's trajectory, while connecting block 12 ensures the synchronous displacement accuracy of the movable L-plate 13.
