For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Figure 1 , Figure 2 and Figure 3 A flange quick-lifting device as shown in, includes a top cross beam 1 with an X-shaped structure. A bottom-side assembly groove 2 with an outer opening is formed on the lower surface of the top cross beam 1. A bottom adjusting arm 3 is rotatably installed at the lower end of the top cross beam 1. A hook 4 with an integral structure is provided at the bottom end of the bottom adjusting arm 3. A guide post sleeve 5 is provided at the central position of the top cross beam 1. A connecting shaft 6 is movably inserted into the guide post sleeve 5. A lifting lead screw 7 with an integral structure is axially fixed at the bottom end of the connecting shaft 6. An internally threaded lifting frame 8 is threadedly assembled on the outer side of the lifting lead screw 7. A control link 9 is installed between the internally threaded lifting frame 8 and the bottom adjusting arm 3.

[0030] In order to cooperate with hoisting, a top hanger 10 is fixedly assembled at the upper end of the top cross beam 1.

[0031] The overhead crane is connected to the lifting device by sleeving a hook on the top hanger 10.

[0032] In order to improve the structural stability, a spring 11 is sleeved on the periphery of the lifting lead screw 7 above the upper end of the internally threaded lifting frame 8.

[0033] The upper end of the spring 11 presses against the inner top surface of the top cross beam 1, and the lower end of the spring 11 presses against the upper surface of the internally threaded lifting frame 8.

[0034] In order to cooperate with the bottom support, a support sheet metal 12 is welded and fixed on the upper surface of the top cross beam 1.

[0035] In order to cooperate with the top control, a connecting shaft rod 13 is rotatably installed at the top end of the connecting shaft 6.

[0036] The coupling rod 13 is turned downward and supported on the upper surface of the supporting sheet metal 12 to ensure the supporting stability.

[0037] The coupling rod 13 is a control rod with an L-shaped structure. The longitudinal section at the bottom of the coupling rod 13 is inserted into the coupling at the top end of the coupling shaft 6 and axially connected to the coupling shaft 6. The lateral turning of the coupling rod 13 can control the rotation of the coupling shaft 6.

[0038] The longitudinal section at the bottom of the coupling rod 13 has an external hexagonal control head that fits with the internal hexagonal control blind hole at the top of the coupling. The coupling rod 13 is connected to the top end of the coupling by inserting the external hexagonal control head into the internal hexagonal control blind hole, and the synchronous rotation of the coupling shaft 6 is controlled by turning the coupling rod 13.

[0039] Working principle: The device is lifted by a crane and transported to the flange. Then, the lifting cable of the crane is separated from the top beam 1. Then, the coupling rod 13 is inserted into the coupling at the top end of the coupling shaft 6. The coupling shaft 6 drives the lifting screw rod 7 to rotate, controlling the inner-threaded lifting frame 8 to descend inside the bottom adjusting arm 3. The inner-threaded lifting frame 8 drives the control link 9 to extrude outward, controlling the bottom adjusting arm 3 to turn outward, inserting the hook 4 into the lower end of the inner side of the flange. Then, the lifting cable of the crane is connected to the top beam 1. The device is driven by the crane to move the flange to the opening position above the processing equipment. Then, the coupling rod 13 is inserted into the coupling at the top end of the coupling shaft 6. By turning to drive the lifting screw rod 7 to rotate in the reverse direction, the inner-threaded lifting frame 8 is lifted inside the bottom adjusting arm 3. The inner-threaded lifting frame 8 drives the control link 9 to turn inward, controlling the bottom adjusting arm 3 to turn inward, separating the hook 4 from the lower end of the inner side of the flange.

[0040] In order to facilitate the adjustment of the connection position and adapt to different specifications of flanges and processing equipment, a horizontal assembly shaft hole 14 communicating with the inside of the bottom assembly groove 2 is provided on the side wall of the top beam 1, and internally matching internal assembly shaft holes 15 are provided inside both the bottom adjusting arm 3 and the control link 9.

[0041] In order to cooperate with the movable assembly, the bottom adjusting arm 3 is movably assembled with the bottom assembly groove 2 through the top assembly shaft penetrating through the inside of the horizontal assembly shaft hole 14, and the bottom adjusting arm 3 and the control link are movably assembled through the connecting shaft inside the internal assembly shaft hole 15.

[0042] When the lifting screw rod 7 drives the inner-threaded lifting frame 8 to perform lifting adjustment and guiding along the lifting screw rod 7 by rotation, by over-extruding the control link 9, the control link 9 extrudes the bottom adjusting arm 3 outward. The hook 4 at the bottom of the bottom adjusting arm 3 is stuck at the bottom of the flange. At this time, the hook on the crane is put on the top hanger 10, and the flange can be lifted.

[0043] To cooperate with the sunken installation, a horizontal sunken groove 16 communicating with the horizontally arranged assembly shaft hole 14 is provided on the inner side surface of the bottom-side assembly groove 2.

[0044] The horizontal sunken groove 16 can improve the utilization rate of the internal space without affecting the internal position adjustment.

[0045] To cooperate with the external infrared positioning and improve the accuracy of hoisting, a side-mounted infrared positioning module 17 is fixedly assembled on the side wall of the top cross beam 1 by bolts.

[0046] The side-mounted infrared positioning module 17 is fixed on the side wall of the top cross beam 1 by lateral bolts. The lateral bolts are installed inside the horizontally arranged assembly shaft hole 14 and the horizontal sunken groove 16. The side-mounted infrared positioning module 17 measures the distance to the ground by the optical ranging method of the existing technology, and then an LED display lamp for displaying the measured distance is installed on the side wall of the top cross beam 1. When the detected distance on one side is much greater than the other positions, it will change from yellow in the normal state to red. When the device is hoisted and moved, the distance measured downward by the side-mounted infrared positioning module 17 is constantly changing. At this time, the side-mounted infrared positioning module 17 controls the LED display lamp to display a flashing yellow. When the distances measured downward by the side-mounted infrared positioning modules 17 at different positions are the same, at this time, the hanging infrared positioning module 17 controls the LED display lamp to display a constantly lit green. When the side-mounted infrared positioning module 17 moves to the upper opening position of the heating furnace, the measured distance of the side-mounted infrared positioning module 17 suddenly becomes larger. At this time, the LED display lamp at this side position displays a constantly lit red, which is convenient for control.

[0047] To cooperate with adjusting the stability of the device in different directions, an electronically controlled counterweight module 18 is fixedly bolted on the upper surface of the top cross beam 1.

[0048] The electronically controlled counterweight module 18 includes a top guide rail fixed on the upper surface of the top cross beam 1, a top counterweight block slidably installed inside the top guide rail, and a lateral adjusting strut fixed on the side wall of the top guide rail. The extended end of the lateral adjusting strut is inserted into the top guide rail and connected to the side wall of the top counterweight block. The lateral adjusting strut controls the top counterweight block to slide and adjust along the inside of the top guide rail by stretching.
