[0020] like Fig. 9 , Fig.10 , Fig.11As shown, the automatic threading and detection device 6 includes a mobile frame 61, and the mobile frame 61 is fixedly connected to the longitudinal beam 3. The mobile frame 61 is a T-shaped structure, and an X-direction slider 62 is arranged below the horizontal frame in the mobile frame 61, and the X-direction slider 62 is slidably arranged on the X-direction linear slide rail 38 of the longitudinal beam 3.

The pinion 65 is driven by an X-direction adjustment reduction motor 66, and the X-direction adjustment reduction motor 66 is arranged on the side of the mobile frame 61. The X-direction adjustment reduction motor 66 can be located in the middle hollow of the longitudinal beam. Such a structure realizes the X-direction movement of the automatic threading and detection device 6.

[0021] A guide cylinder 63 is provided at the bottom of the mobile frame 61. One end of the guide cylinder 63 is mounted on one side of the mobile frame 61. The other end of the guide cylinder directly passes through a screw 631. An inner guide groove is provided inside the guide cylinder. A guide groove shaft is installed on the screw inside the guide cylinder. The guide groove shaft is a conical structure.

[0022] A retracted-in-place detection proximity switch 67 is installed at the shaft extension on the other side of the moving frame 61, and a raised-in-place detection proximity switch 68 is installed at the end shaft of the guide cylinder.

[0023] like Fig.12 , Fig.13 As shown, the horizontal eccentric adjustment upper frame 4 includes two upper bearing beams 41 arranged in parallel, one end of the upper bearing beams 41 is connected by an intermediate cross beam 42, and the other end of the upper bearing beams 41 is connected by two arc beams 43, the two arc beams have the same curvature, and a sliding gap 44 is arranged between the two arc beams 43. A swing mechanism 45 is arranged above the two arc beams 43, and the shape of the swing mechanism 45 corresponds to the two arc beams 43. A heavy-load guide wheel 48 is arranged below the swing mechanism 45, and the swing mechanism 45 is arranged to slide with the two arc beams 43.

[0024] A first through hole is provided on the middle cross beam 42, and a first screw 46 is provided in the first through hole. The middle cross beam 42 and the transverse beam 2 are fixed together by the first screw 46, and the first screw 46 is the rotation center. A second through hole is provided in the swing mechanism 45, and a second screw 47 is also provided in the second through hole. The end of the second screw 47 is fixedly connected to the T-shaped load-bearing beam 1.

[0025] In addition, a servo cylinder 18 is provided on the T-shaped load-bearing beam 1. One end of the cylinder body of the servo cylinder 18 is hinged on the T-shaped load-bearing beam 1. The output shaft of the servo cylinder 18 is hinged on the connecting beam 49. The connecting beam 49 is connected between the middle cross beam 42 and the arc beam 43. Figure 2 , Fig.12 shown.

[0026] It should be noted that both ends of the two parallel upper load beams 41 are provided with detachable trolley connection points 7, through which the crane trolley is connected. Since the crane trolley is stationary, the quadrilateral structure composed of the upper load beam 41, the middle cross beam 42 and the two arc beams 43 does not undergo eccentric displacement. In this way, when the servo cylinder 18 is actuated, the lower T-shaped load beam 1 is fixed at one point, and the other point will swing eccentrically in the sliding gap 44 with the swing mechanism 45.

[0027] The working principle of the present invention is: The object hoisted by the present invention is a nuclear underwater storage tank, which has four lifting lugs on the top, each with a lifting hole. At the same time, no matter what kind of storage tank, four guide holes are fixed on the top, and the size of the guide holes does not change with the difference of the storage tank, and there is a same bearing plane beside the guide holes. In any case, the height difference between the lifting hole and the bearing surface is constant.

[0028] The lifting device of the present invention is made of all stainless steel, has four-point lifting and four-point anti-sway devices on the upper part, and has multi-point alignment and multi-point lifting on the lower part.

[0029] When working, the crane falls straight down to the top of the storage tank, and the anti-sway wire rope plays an anti-sway role during the falling alignment process. The guide cone 52 is aligned with the guide hole on the storage tank. If there is a phase deviation, the servo cylinder 18 in the horizontal eccentric adjustment frame 4 is actuated, and the servo cylinder 18 pushes or pulls the T-shaped load-bearing beam 1 to realize the eccentric rotation of the T-shaped load-bearing beam 1 around one end, and the centering and deviation correction are realized through the movement of the heavy-duty guide wheel 48. After the four guide cones 52 are aligned, the crane continues to fall until the top pin 53 of the sling touches the bearing surface of the storage tank. After further falling, the top pin 53 of the sling moves up, which drives the detection switch 57 to move up, triggering the detection switch 57 to detect and stop falling. Even if the crane falls further due to inertia, the upper and lower falling surfaces of the sling contact with the bearing surface to form a mechanical limit, and the fall is now completely completed.

[0030] Next, the motor reducer 16 on the T-shaped load-bearing beam 1 is operated, and the Y-direction adjustment of the longitudinal beam 3 is driven by the T-shaped lead screw 15. After the longitudinal beam 3 runs to a suitable position on the Y-direction linear slide rail 13 of the load-bearing beam, the motor reducer 16 stops working. Then the X-direction adjustment reduction motor 66 is started, and the X-direction adjustment reduction motor 66 is driven by the gear rack to drive the automatic threading and detection device 6 to move. When the retracted detection proximity switch 67 and the raised detection proximity switch 68 in the automatic threading and detection device 6 detect the alignment state with the hoisting hole on the storage tank in real time, after alignment, the threading reduction motor 64 is started, so that the shaft passes through the hoisting hole through the synchronous belt, and the hole is in place for detection and detection, and complete engagement is achieved, thus completing the automatic alignment and connection process.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
