The fixed column (14) is welded to the frame column.

[0039] Furthermore, if Figure 2 As shown, in the frame assembly (1), the main frame (4) includes four columns, three upper beams and a bottom frame, the columns are respectively a first column (32), a second column (33), a third column (34) and a fourth column (35), the upper beams are respectively a first upper beam (36), a second upper beam (37) and a third upper beam (38), the bottom frame includes a first long frame (39), a second long frame (40), and two short frames (41) vertically fixed to the two end points of the long frames, the lower ends of the four columns are respectively fixed to the four corners of the bottom frame, the first column and the second column are respectively fixed to the four corners of the bottom frame, The upper ends of the first column, the second column and the third column, and the third column and the fourth column are respectively enclosed and fixedly connected with the first upper beam, the second upper beam and the third upper beam; a vertical rod (42) is fixedly connected between the second upper beam and the second long frame (40); the first long frame (39) is parallel to the second long frame (40); a support rod is arranged between the cross rod (44) and the second long frame (40); the installation base (5) is welded to a support position parallel to the two short frames (41) in the bottom frame; and the installation top seat (6) is welded to a position parallel to the first upper beam and the third upper beam through a connecting block (7).

[0040] Furthermore, if Figure 3 As shown, the first long frame (39) is divided into two sections of square tubes, one end of the square tube is connected to the column, the other end of the square tube is fixedly connected to the support tube between the cross bar (44), a forklift opening (43) is arranged below the square tube, and a forklift opening (43) is arranged below the second long frame.

[0041] Furthermore, a universal wheel (10) is installed below the connection between the bottom frame and the column, and the manual towing (11) and the vehicle towing (12) are respectively screwed to two short frames (40) in the bottom frame, and a nameplate (13) is provided on the side of the main frame.

[0042] Furthermore, the main frame (4) adopts an aluminum profile structure and is welded by 2.5 mm thick square tubes. A plurality of support tubes are designed below the mounting base (5) in a direction perpendicular to the mounting base (5) to improve the overall strength. One end of the support tube is vertically fixed to the short frame (41), and the other end is vertically fixed to a short tube parallel to the short frame. A cross bar (44) is fixedly connected between the two short tubes.

[0043] Furthermore, the upper stacking corners (8) are plugged into the upper edges of the four columns in the main frame (4), and the lower stacking grooves (9) are glued to the lower edges of the four columns in the main frame (4).

[0044] The forklift opening (43), together with the manual towing (11) and the vehicle towing (12), realizes three modes of transport functions, namely, manual towing transport, rope-threaded vehicle towing transport, and forklift transport, with more diversified functions to meet different usage requirements; the upper stacking corner (8) and the lower stacking slot (9) realize the stacking function, which is convenient for storage, saves space, and reduces the cost of use; the universal wheel (10) realizes the movable function of the transport device, which is convenient for people and vehicles to tow; the nameplate (13) design plays a role in facilitating the user to record and display the relevant information of the workpiece.

[0045] like Figure 4 As shown, in the pressure rod assembly (2), the fixed column (14) is respectively welded on the column of the main frame (4) and has a rotatable function; one end of the rotating rod (15) is plugged into the fixed column (14), and the other end is welded and fixed to the crossbeam (16); the foam groove (17) is welded under the crossbeam (16); and the foam (18) is installed in the groove of the foam groove (17). The pressure rod assembly 2 can be turned over. Due to the action of the connecting rod linkage device, only the first row needs to be fixed to limit the movement of other seesaws, which is convenient for taking away and storing workpieces; the foam 18 is provided to press the workpiece, and its shape fits the workpiece, which can not only play the role of fixing the workpiece, but also its material can prevent the workpiece from being scratched.

[0046] like Figure 5 and Figure 6As shown, in the column seesaw assembly (3), the two column bending plates (19) are respectively welded and fixed to the upper and lower connecting plates (20); the two ends of the seesaw (21) are fixed between the two column bending plates (19) through a rotating rod (15) and are arranged in a parallel direction with the upper and lower connecting plates (20); the fixed round tube (22) sleeved on the rotating rod (15) is welded to the seesaw (21); the inner side of the seesaw (21) is vertically fixed with a PP support plate (23) by screw connection, the outer side of the seesaw (21) is inclined outward, and a limiting column (31) is inserted at the bottom of the seesaw (21); the limiting pin assembly (30) is welded to the outwardly inclined side of the seesaw (21) through a round tube (24), and is connected to the linkage block (29) and another adjacent seesaw (21) through the limiting pin assembly (30); the linkage block (29) is provided with an oblong hole, and the limiting pin assembly (30) can be in the long round hole. The PP support plate (23) is designed to match the shape of the threshold reinforcement beam and is connected to the seesaw (21) by bolts. The PP support plate (23) is designed to match the shape of the workpiece and can be replaced according to the shape of the workpiece to match the PP support plate. The PP support plate (23) plays the role of supporting the workpiece as a whole. A connecting rod linkage mechanism is designed to drive the seesaw assembly to rotate. The overall rotation range is effectively controlled by the oblong hole position on the linkage block (29) and the limit shaft (28) and the iron block (26) to avoid the phenomenon of damaging the workpiece. The linkage mechanism can penetrate the seesaw as a whole. By lifting the seesaw at the bottom, the connecting rod mechanism will drive the other seesaws on the same side to move together, and then the seesaws are lowered layer by layer according to needs to place the workpieces. After the workpieces are stored from bottom to top, the upper pressure rod assembly (2) presses the workpieces on the first layer, and through the connecting rod linkage mechanism, the movement of the other seesaws is restricted at the same time. If there is a bump during transportation, the workpiece can be prevented from falling, which facilitates storage and retrieval and improves the use efficiency. The limit shaft (28) can effectively ensure that the workpiece remains in a horizontal state after being loaded, and plays a limiting role, so that the workpiece is fixed in the corresponding sub-grid. The limit column (31) also plays the role of limiting the workpiece to prevent the workpiece from moving left and right.

[0047] Furthermore, if Fig. 9 As shown, the column bending plate (19) is a U-groove structure, which not only strengthens the strength of the parts, but also can hide the left and right related connecting parts to achieve an aesthetic effect; a round hole is provided on the column bending plate (19), and a limit shaft (28) is welded to the outwardly inclined side of the seesaw (21). The seesaw (21) is inserted into the corresponding holes of the two column bending plates (19) through the limit shaft (28), thereby fixing the horizontal position.

[0048] Furthermore, foam (18) and an iron block (26) are fixed on the seesaw (21), and the outer inclined side of the seesaw (21) is connected to the iron block (26) so that when the workpiece is taken out, the seesaw (21) is rotated and tilted toward the side without the workpiece due to the gravity of the iron block (26), so as to facilitate the further taking out of the lower layer of workpieces. The foam (18) is fixed under the other outer inclined side of the seesaw (21) to prevent the seesaw (21) from colliding with the workpiece and scratching the workpiece during rotation.

[0049] like Fig.10 As shown, a reversible sill reinforcement beam special transport device is provided, wherein the column seesaw assembly (3) is screwed onto the mounting base (5) and the mounting top seat (6) of the frame assembly (1), and the pressure rod assembly (2) is welded onto the frame assembly (1) via a fixing column (14). The two ends of the sill reinforcement beam workpiece (45) are hooked onto the PP support plate (23) of the column seesaw assembly (3), and the sill reinforcement beam workpiece (45) is stored from bottom to top, and finally the first layer of workpieces is pressed by the pressure rod assembly 2. Even if there is a bump under the action of the linkage mechanism, the workpiece will not loosen or fall due to the rotatability of the seesaw, and the workpiece needs to be taken out from top to bottom by opening the pressure rod assembly (2).

[0050] like Figure 7 As shown, when the seesaw (21) is lifted, the seesaw (21) moves clockwise through the rotating rod (15), and the linkage block (29) rotates accordingly through the limit pin (30), driving the upper seesaw to rotate clockwise, so that only the bottom layer needs to be rotated to achieve the overall linkage; when placing objects, start from the bottom layer, and when it is rotated counterclockwise to horizontal, due to the oblong hole feature of the linkage block (29), it has a separate displacement space, so it will not drive the upper seesaw to rotate at the same time, and the workpieces can be placed layer by layer; conversely, Figure 8 This is a schematic diagram of the linkage of the seesaw being lowered layer by layer. After the workpiece is placed, only the top seesaw needs to be fixed. Due to the effect of the linkage mechanism, the seesaws below cannot rotate freely, which facilitates overall fixed transportation and saves manpower and material resources.

[0051] The device is mainly made of aluminum alloy, which is light in weight and has good corrosion resistance. The product adopts a multifunctional design concept as a whole, with high assembly efficiency, providing convenient conditions for workers to store and remove workpieces.
