DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-4 , the utility model provides a container transport semi-trailer loading and unloading mechanism, including a loading and unloading component 1 and a telescopic component 2;

[0025] The loading and unloading assembly 1 comprises a crane body 11, a connecting seat 12, a mounting seat 13 and a supporting shaft 14. The telescopic end of the crane body 11 is hingedly connected to the connecting seat 12. The mounting seat 13 is fixedly arranged at the bottom end of the connecting seat 12. The middle part of the mounting seat 13 is rotatably connected to the supporting shaft 14. The middle part of the supporting shaft 14 is fixedly arranged with a first gear 15. The bottom end of the supporting shaft 14 is fixedly arranged with a fixing platform 16. The middle part of the bottom end of the fixing platform 16 is fixedly arranged with an electromagnetic suction cup 18. The electromagnetic suction cup 18 generates a magnetic field when it is energized, which can adsorb metal objects, thereby realizing the convenient adsorption of small containers.

[0026] A servo motor 131 is fixedly disposed on one side of the surface of the mounting seat 13, and a second gear 132 is fixedly disposed on the transmission shaft of the servo motor 131;

[0027] The first gear 15 is meshedly connected with the second gear 132;

[0028] Specifically, first, the staff can adjust the forward and reverse rotation of the servo motor 131 through the control room of the crane body 11. The transmission shaft of the servo motor 131 drives the first gear 15 to rotate through the second gear 132. When the first gear 15 rotates, it can drive the fixed platform 16 to rotate at a reduced speed, thereby realizing the angle adjustment of the container, and the adjustment method is more flexible.

[0029] Embodiment 2:

[0030] The telescopic assembly 2 includes two support rails 21, two telescopic columns 22 and a gripping mechanism 23. The two support rails 21 are fixedly arranged at both ends of the fixed platform 16, and the interior of each support rail 21 is slidably connected with a telescopic column 22.

[0031] The grabbing mechanism 23 includes two connecting columns 230, which are respectively arranged at one end of the two telescopic columns 22. Both sides of the bottom end of each connecting column 230 are provided with connecting blocks 231, and the middle of each connecting block 231 is provided with a limiting groove 232.

[0032] A mounting column 24 is fixedly disposed on one side of the top end of each support rail 21;

[0033] An electric hydraulic cylinder 25 is fixedly disposed on the surface of each mounting column 24;

[0034] A fixing block 26 is fixedly disposed on one side of the surface of each telescopic column 22, and the telescopic ends of the two electric hydraulic cylinders 25 are fixedly connected to the surfaces of the two fixing blocks 26 respectively;

[0035] Specifically, first, with the cooperation of the two electric hydraulic cylinders 25, the distance between the two connecting columns 230 can be adjusted so that the connecting blocks 231 at the bottom ends of the two connecting columns 230 correspond to the connecting holes on the top of the container. The height is adjusted through the telescopic end of the crane body 11 so that the connecting block 231 is inserted into the connecting hole on the top of the container. Then, the telescopic end of the electric hydraulic cylinder 25 is contracted through the control room, and the limiting groove 232 in the middle of the connecting block 231 clamps the connecting hole on the top of the container, thereby realizing a quick connection with the container.

[0036] When in use, firstly, the container is lifted and lowered and moved horizontally within a large range, so as to facilitate moving the container from the semi-trailer to the ground or from the ground to the semi-trailer. The container needs to be quickly connected. Adjustable length telescopic columns 22 are arranged at both ends of the fixed platform 16 through support rails 21. The crane body 11 controls the length of the telescopic end of the electric hydraulic cylinder 25 through the control room. The telescopic end of the electric hydraulic cylinder 25 drives the telescopic column 22 to move synchronously through the fixed block 26. The telescopic column 22 is connected to the connecting column 230. With the cooperation of the two electric hydraulic cylinders 25, the distance between the two connecting columns 230 can be adjusted so that the connecting blocks 231 at the bottom ends of the two connecting columns 230 correspond to the connecting holes provided at the top of the container. The telescopic end of the crane body 11 is height-adjusted so that the connection block 231 is inserted into the connection hole on the top of the container. Then, the telescopic end of the electric hydraulic cylinder 25 is retracted through the control room, and the limiting groove 232 in the middle of the connection block 231 clamps the connection hole on the top of the container, thereby realizing a quick connection with the container, and the movement of the container is completed with the cooperation of the telescopic end of the crane body 11, which makes loading and unloading more convenient. At the same time, in order to facilitate the loading and unloading of small containers, an electromagnetic suction cup 18 is provided at the bottom end of the fixed platform 16. The electromagnetic suction cup 18 generates a magnetic field when it is energized, which can adsorb metal objects, thereby facilitating the adsorption of small containers, and can realize the rapid lifting and horizontal movement of the container, thereby improving the loading and unloading efficiency;

[0037] At the same time, in order to ensure that the container can be accurately placed on the transport trailer, the container needs to be adjusted at an angle. The staff can adjust the forward and reverse rotation of the servo motor 131 through the control room of the crane body 11. The transmission shaft of the servo motor 131 drives the first gear 15 to rotate through the second gear 132. When the first gear 15 rotates, it can drive the fixed platform 16 to rotate at a reduced speed, thereby achieving the angle adjustment of the container. The adjustment method is more flexible. In order to protect the line, the rotation range of the fixed platform 16 is 0-60 degrees.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
