DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 1

[0029] See also Figures 1 to 3The utility model provides a technical solution: a loading platform for container lifting, comprising a bottom plate 1 and a platform body 5, an upward plate 4 is rotatably installed at one end of the platform body 5, and an outward extension plate 1 501, an outward extension plate 2 502 and an outward extension plate 3 503 are respectively fixedly installed at the other end of the platform body 5, and the outward extension plate 1 501, the outward extension plate 2 502 and the outward extension plate 3 503 are respectively from the front to the back of the platform body 5. A connecting shaft 7 is rotatably installed between the outward extension plate 1 501 and the outward extension plate 3 503, and the connecting shaft 7 includes a smooth section 701 and a recessed section 702, and the smooth section 701 is distributed between the outward extension plate 2 502 and the outward extension plate 3 503, The recessed section 702 is distributed between the extended plate 1 501 and the extended plate 2 502, and the outer side surface of the smooth section 701 is rotatably installed with a downward plate 6, and a reset spring 8 is fixedly installed on one side of the extended plate 2 502, and a sliding column 9 is fixedly installed on the end of the reset spring 8 away from the extended plate 2 502, and the sum of the original length of the reset spring 8 and the height of the sliding column 9 is equal to the length of the recessed section 702, and a dense tooth section 901 is arranged on the outer side of one end of the sliding column 9, and an inner convex through hole 903 is opened in the sliding column 9, and the inner convex through hole 903 is adapted to the recessed section 702, and a handle 902 is fixedly installed on one end of the sliding column 9, and an inner gear ring 5011 is arranged in the extended plate 1 501, and the inner gear ring 5011 is meshed with the dense tooth section 901.

[0030] When in use, due to the different specifications of trucks, the heights of containers are different. The existing loading platform needs to use structures such as telescopic rods for adjustment. This method has the disadvantage of being expensive. Before the start of work, the truck enters the corresponding position, presses the sliding clamp column 9, and the inner convex through hole 903 of the sliding clamp column 9 slides in the concave section 702 of the rotating column 10. At this time, the return spring 8 is compressed to store elastic potential energy until the dense tooth section 901 of the sliding clamp column 9 is disengaged from the inner gear ring 5011 of the extended plate 1 501. At this time, the sliding clamp column 9 is in The circumferential direction is free. By turning the handle 902, the lower end of the descending plate 6 can be controlled to be flush with the container of the truck through the cooperation of the inner convex through hole 903 and the concave section 702, so as to achieve the purpose of adjusting the descending plate 6, which can be adapted to trucks of different specifications. After adjustment, the sliding clamp column 9 is loosened, and the reset spring 8 releases the elastic potential energy to push the sliding clamp column 9 back to its original position. The dense tooth section 901 of the sliding clamp column 9 is again matched with the inner gear ring 5011 of the extended plate 1 501, and the sliding clamp column 9 is re-fixed. The adjustment structure is simple and inexpensive.
