DETAILED DESCRIPTION

[0020] In order to make the technical solution of the present invention more clear, the present invention will be further described below with reference to specific embodiments of the drawings.

[0021] like Figure 1-6As shown, according to an embodiment of the present invention, a lifting and folding box beam storage device includes a base plate 1, a mounting tube 2 is vertically provided in the middle of the surface of the base plate 1, and a guard plate mounting groove 11 is opened along the edge, a guard plate 12 is installed in the guard plate mounting groove 11, and a rotating shaft 13 passes through the guard plate 12 and is rotatably connected to the two ends of the inner side of the mounting groove 11, and a fixed interface 121 is provided on the end face of the guard plate 12, a partition 21 is provided on the surface of the mounting tube 2, and a reinforcement plate 22 is provided between the partitions 21, a hydraulic cylinder 3 is provided on the bottom surface of the inner side of the mounting tube 2, and a column 41 passes through the mounting tube 2 and contacts the hydraulic cylinder 3, and a cover plate 4 is fixedly connected at its end face, and a cross bar 5 is vertically provided on the outer surface, and a limiting rod 51 is vertically provided at the end of the lower bottom surface of the cross bar 5, and a reinforcing rod 52 is fixedly connected at the angle between the limiting rod 51 and the cross bar 5, and is connected to the outer surface of the column 41, and a fixed latch rod 42 is vertically provided on the lower bottom surface of the cover plate 4.

[0022] The bottom plate 1 and the cover plate 4 are three-dimensional hexagonal structures. During operation, multiple box beams can be placed at the same time due to the characteristics of the three-dimensional hexagonal structure, thereby reducing the occupied area.

[0023] Among them, six partitions 21 are provided on the surface of the installation cylinder 2; when working, the partitions 21 are used to separate and store the box beams to prevent the box beams from colliding and wearing each other.

[0024] Among them, the area of ​​the cover plate 4 is equal to the area of ​​the bottom plate 1; when working, the hydraulic cylinder 3 drives the column 41 to descend, closes and protects the top of the box beam, and reduces the gap between the cover plate 4 and the guard plate 12.

[0025] The partition 21 is fixedly connected to the surface of the bottom plate 1 , and when in operation, it reinforces the partition 21 .

[0026] Among them, a reinforcement rod 52 is fixedly connected to the angle between the limit rod 51 and the cross bar 5; when working, the limit rod 51 is reinforced by the reinforcement rod 52.

[0027] Among them, the end face of the guard plate 12 is provided with a fixing interface 121; when working, the hydraulic cylinder 3 drives the fixing latch rod 42 to descend and insert into the fixing interface 121, thereby limiting and fixing the guard plate 12.

[0028] Working principle: First, place the box girder on the surface of the bottom plate 1, then rotate the guard plate 12 to close and protect the outside of the box girder, then start the hydraulic cylinder 3 to drive the column 41 to descend, closing and protecting the top of the box girder. During the process of the column 41 descending, the limit rod 51 and the fixed latch rod 42 will be driven to descend, so that the limit rod 51 is inserted into the gap in the middle of the box girder to limit it, and the fixed latch rod 42 will descend and be inserted into the fixed interface 121 to limit and fix the guard plate 12;

[0029] In addition, in order to protect the surface of the box beam and prevent damage, rubber pads can be provided on the surface of the bottom plate 1 and the guard plate 12.

[0030] The above embodiments can be combined with each other and further implemented if they are not mutually exclusive.
