[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] In order to solve the problem that the special container lifting device is difficult to adjust the position of the hanging ring connected to the external crane hook when in use, when the cargo is loaded heavily, the middle deflection sinks, and the container is easily deformed and damaged during the lifting process, please refer to Figures 1 to 5 The structure of the device body is a special container body 1 and a support frame 2 for supporting the special container body 1. The top surface of the support frame 2 is welded to the special container body 1. The set support frame 2 provides support and fixation for the special container body 1. The two inner side walls of the support frame 2 are embedded with fixed bearings 3, and the inner ring of the fixed bearing 3 is interference fit with a rotating block 4. The set fixed bearing 3 fixes the rotation position of the rotating block 4, and simultaneously realizes the rotation position of two rotating blocks 4 and one support frame 2.

[0027] A rotating plate 5 is welded to the end face of the rotating block 4, and a threaded rod 6 with reverse threads is welded to the adjacent sides of the two rotating plates 5. Under the connecting action of the rotating plate 5, the rotation position of the threaded rod 6 is fixed. The threaded rod 6 is threadedly connected to two threaded plates 7 with reverse threads. When the threaded rod 6 rotates, the two threaded plates 7 with reverse threads move to the reverse position along the threaded path of the threaded rod 6. Connecting plates 8 are welded to the two end faces of the threaded plate 7. A hanging ring 9 is welded to the end face of the connecting plate 8 for hanging with the hook of an external crane for lifting and transporting the special container body 1. The provided connecting plate 8 provides a connecting effect, so that the two hanging rings 9 move synchronously with a threaded plate 7, and the lifting and transportation of the special container body 1 is realized by hanging the hook of an external crane with the hanging ring 9. The four hooks of the external crane are hung with the four hanging rings 9 of the lifting device.

[0028] Through grooves are provided on the two outer walls of the support frame 2, and the inner walls of the two through grooves of the support frame 2 are slidably connected to the four connecting plates 8, further fixing the stability of the moving paths of the four connecting plates 8. One end of the rotating blocks 4 away from the rotating plate 5 is connected to a rotating motor 10 through a coupling, and the fixed end of the rotating motor 10 is detachably connected to the support frame 2 through bolts. The set rotating motor 10 provides power, and the spacing between the two pairs of hanging rings 9 is adjusted during the transmission process to adapt to the lifting and transportation needs of special containers, so as to prevent the middle deflection from sinking when the cargo is loaded too heavily, and the special container body 1 from being deformed and damaged.

[0029] The end faces of the two threaded plates 7 are slidably connected to the inner side walls of the support frame 2. The support frame 2 is set to fix the moving path of the two threaded plates 7, and at the same time prevent the two threaded plates 7 from rotating synchronously with the rotation of the threaded rod 6, thereby improving the structural stability of the device parts. The centrifugal side of the two rotating plates 5 is in frictional contact with the support frame 2. The two rotating plates 5 further fix the rotation position of the threaded rod 6. Support plates 11 are welded at both ends of the bottom of the support frame 2, and the two support plates 11 are respectively located at the bottom edge of the support frame 2. The two ends of the bottom of the support plate 11 are welded with an internal hollow telescopic outer rod 12, so that the two telescopic outer rods 12 are welded to the bottom surface of the support plate 11, and the inner cavity of the telescopic outer rod 12 is slidably connected with a moving plate 13, so that the moving plate 13 moves along the inner cavity of the telescopic outer rod 12, and the top surface of the moving plate 13 is welded with a moving end of a damper 14 for providing buffering and shock absorption for the hoisted special container body 1.

[0030] The fixed end of the damper 14 is welded to the inner top wall of the telescopic outer rod 12, and a telescopic inner rod 15 is welded to the bottom of the movable plate 13. The side of the telescopic inner rod 15 is embedded in the telescopic outer rod 12 for sliding connection. A support seat 16 is welded to the bottom of the telescopic inner rod 15. The set support seat 16 provides support and is hung with the hook of the external crane and the hanging ring 9 of the lifting device to realize the lifting and transportation of the special container body 1. After the special container body 1 is lifted and transported to the designated position, the four support seats 16 contact the ground, so that the telescopic inner rod 15 extends into the inner cavity of the telescopic outer rod 12, and then the movable plate 13 moves along the inner cavity of the telescopic outer rod 12, so that the movable plate 13 squeezes the moving end of the damper 14, so that the damper 14 works, thereby realizing the buffering and shock absorption effect on the special container body 1 and preventing damage to the special container body 1.

[0031] The rotating motor 10 and the damper 14 are both prior art. Their working principles, sizes and models are irrelevant to the functions of this application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] When using this special container lifting device, the user connects the hook of an external crane to the four hanging rings 9 to realize the lifting and transportation of the special container body 1, starts the rotating motor 10, and the output shaft of the rotating motor 10 drives the threaded rod 6 to rotate during the rotation, thereby causing the two threaded plates 7 to move in opposite directions along the threaded path of the threaded rod 6. Under the connection provided by the connecting plate 8, the spacing between the four hanging rings 9 is adjusted, and the fixed bearing 3, the rotating block 4 and the rotating plate 5 fix the rotation position of the threaded rod 6.

[0034] After the special container body 1 is hoisted and transported to the designated location, the four support seats 16 provide support, so that the telescopic inner rod 15 extends into the inner cavity of the telescopic outer rod 12. At the same time, the movable plate 13 moves along the inner cavity of the telescopic outer rod 12, so that the movable plate 13 pushes the movable end of the damper 14 located in the inner cavity of the telescopic outer rod 12, causing the damper 14 to work and perform buffering and shock absorption.
