[0016] 1. The utility model is equipped with a double-layer steel crisscross stacking rack device, which increases the stacking quantity per unit area; the connection between the double-layer stacking racks adopts a split, detachable square steel column structure, which realizes the turnover and reuse of the steel crisscross racks and square steel columns within a certain range, avoids material waste, and achieves the goal of green material saving; at the same time, unlike the traditional low transportation efficiency, due to the realization of double-layer shelf transportation, the number of single-vehicle transportation is nearly doubled, the transportation volume of unit vehicle is increased, the transportation efficiency is guaranteed, and the cost is saved.

The rectangular thick steel plates 15 extend into the space between the ends of the upper steel frame 4 or the lower steel frame 1 and the limiting iron baffles 3 to connect the rectangular thick steel plates 15 to the upper steel frame 4 or the lower steel frame 1.

[0029] The bottom of the square steel column is fixed with a connecting structure device 11, which is inserted into the four ends of the lower steel well frame 1 to connect the square steel column with the lower steel well frame 1. The square steel column is effectively connected to the lower steel well frame 1 through the connecting structure device 11.

[0030] In this embodiment, the lower and upper profiled steel cross-section frames 1 and 4 are each formed by connecting two longitudinal long I-beams 2 and two transverse short I-beams in sequence and enclosing them (welded). The limiting iron baffle 3 is connected between the upper and lower wing plates at the ends of the longitudinal long I-beams 2 of the lower and upper profiled steel cross-section frames 1 and 4 and is arranged parallel to the waist plates of the longitudinal long I-beams 2.

[0031] In this embodiment, a steel plate 6 is provided on the top of the square steel column for supporting the upper steel cross frame 4. A steel baffle is provided on the outside of the steel plate 6 for limiting the movement of the upper steel cross frame 4. Specifically, the square steel column is divided into a left steel column 5 and a right steel column 12. A left steel baffle 7 is provided on the outside of the steel plate 6 on the left steel column 5, and a right steel baffle 13 is provided on the outside of the steel plate 6 on the right steel column 12.

[0037] (2) Insert the connection structure devices 11 at the lower ends of the two left steel columns 5 into the longitudinal long I-beam 2 on the left side of the lower steel cross frame 1 respectively. After the position of the left steel column 5 is adjusted to the specified position, tighten the fastening bolts 10 clockwise to fix the connection structure device 11 to the lower steel cross frame 1;

[0038] (3) Using the same method, the two right steel columns 12 are fixedly connected to the longitudinal long I-beam 2 on the right side of the lower steel well frame 1 through the connecting structure device 11;

[0039] (4) Lower the steel hanger 14 so that the rectangular thick steel plate 15 at the lower end of the lifting chain can extend into the space between the longitudinal long I-beam 2 and the limit iron baffle 3 of the upper steel well frame 4; slowly lift the steel hanger 14 upward so that the four lifting chains on the upper steel hanger 4 are in a taut state, and the four rectangular thick steel plates 15 are firmly stuck to the ends of the upper steel well frame 4;

[0040] (5) Check the status of the prefabricated composite plate and the lifting device. If there is no abnormality, further lift the steel hanger 14, drive the upper steel well frame 4 to slowly rise, and then move it horizontally to the top of the lower steel well frame 1;

[0041] (6) Slowly lower the height of the steel hanger 14 so that the upper steel well frame 4 falls smoothly on the steel plate 6 on the top of the four square steel columns, and adjust the position of the upper steel well frame 4 so that the left steel baffle 7 and the right steel baffle 13 effectively restrict the upper steel well frame 4;

[0042] (7) Continue to lower the steel hanger 14, wait until the four lifting chains are in a relaxed state, pull out all the rectangular thick steel plates 15 at the lower ends of the lifting chains, and raise the steel hanger 14 to complete the entire lifting and stacking process.

[0043] If necessary, the rectangular thick steel plate 15 of the steel hanger 14 can also be extended into the space between the longitudinal long I-beam 2 and the limiting iron baffle 3 of the lower steel well frame 1, and the rectangular thick steel plate 15 can be connected to the lower steel well frame 1 to facilitate the lifting of the entire double-layer shelf.
