[0002] In many industrial fields such as petrochemical, energy and electricity, and shipbuilding, flanges, as an important connecting element, are widely used in the connection between various pipelines and equipment. Flanges are parts that connect shafts to each other and are generally used for connection between pipe ends. Flanges are provided with through grooves and connection holes. With the continuous development of industrial technology and the increasing expansion of production scale, the demand for flange lifting devices is also increasing.

[0003] Traditional flange lifting devices mostly use lifting machinery with wire ropes or chains for lifting operations. Although this lifting method is simple and direct, it has many shortcomings in practical applications. For example, due to the large weight of the flange itself, it is easy to shake or tilt during the lifting process using wire ropes or chains, which increases the difficulty of the operation and safety risks.

[0020] The following is combined with Figure 1 —3 Provide further details of this application.

[0021] An embodiment of the present application discloses a flange lifting device, including a chassis 1, four support rods 2 are arranged on the top of the chassis 1, and movable plates 3 are slidably installed on the four support rods 2, a fixed plate 4 is arranged on the top of the support rods 2, and a rotating structure for driving the movable plate 3 to slide up and down is arranged on the fixed plate 4, a U-shaped fixing seat is also arranged on the fixing plate 4, and a lifting ring 5 is arranged on the top of the U-shaped fixing seat, and four identical mounting frames 6 are also arranged on the outer wall of the chassis 1.

[0022] refer to Figure 1 and Figure 2 The rotating structure includes a motor 7, which is fixedly mounted on the top of the fixed plate 4 and located inside the U-shaped fixed seat. The output end of the motor 7 passes through the through hole opened on the fixed plate 4 and is connected to one end of the screw rod 8. The other end of the screw rod 8 is connected to the bearing seat set at the top of the chassis 1. The screw rod 8 is also adapted to the through hole set at the middle position on the movable disk 3. Four connecting blocks 9 are set on the outer wall of the movable disk 3. A movable rod 10 is rotatably installed in the groove opened at the middle position of the four connecting blocks 9. The other end of the movable rod 10 passes through four mounting frames 6 set on the outer wall of the chassis 1 and is connected to the clamping assembly set inside. To be more specific, the driving motor 7 drives the screw rod 8 to rotate, so that the movable disk 3 slides upward along the four support rods 2. While the movable disk 3 slides upward, it drives one end of the movable rod 10 rotatably connected in the four connecting blocks 9 set on the side wall to rotate, so that the other end of the movable rod 10 drives the clamping assembly to move toward the middle along the four mounting frames 6 at the same time.

[0023] refer to Figure 3 The two ends of the shaft rod 12 are also slidably installed in the symmetrical sliding grooves 13 opened on the two side walls of the installation frame 6. The bottom of the four movable blocks 11 is also provided with T-shaped clamping blocks 14. More specifically, the other ends of the four movable rods 10 are rotatably connected to the four movable blocks 11 through the shaft holes opened on the two side walls of the movable block 11, and the two ends of the shaft rod 12 are also slidably installed in the symmetrical sliding grooves 13 opened on the two side walls of the installation frame 6. When the movable disk 3 slides upward, it drives one end of the movable rod 10 to rotate, so that the other end of the movable rod 10 drives the movable block 11 to move toward the middle along the sliding groove 13 at the same time, thereby driving the T-shaped clamping block 14 set at the bottom to clamp and fix the flange, so that the flange clamping and fixation is more firm, and the stability of the flange during lifting is improved.

[0024] The implementation principle of a flange lifting device in an embodiment of the present application is as follows: when in use, the chassis 1 is driven by a crane to move to the top of the flange that needs to be lifted, and the motor 7 is driven to rotate the screw rod 8 to drive the movable plate 3 to slide upward along the four support rods 2. The four connecting blocks 9 arranged on the outer wall of the movable plate 3 drive one end of the movable rod 10 to rotate, and the other end of the movable rod 10 drives the movable block 11 to slide toward the center position at the same time through the shaft rod 12 along the slide groove 13 opened on the side wall of the installation frame 6, thereby driving the four T-shaped clamping blocks 14 arranged at the bottom to clamp and fix the flange at the same time, so that the flange is clamped and fixed more firmly, thereby improving the stability during lifting, and then driving the crane to install the flange lifting device.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
