DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 4 A flatbed transport semitrailer with a tiltable cargo platform comprises a frame 1, a rotating block 2 is fixedly connected to the top of the frame 1, the rotating block 2 is connected to an L-shaped rotating plate 3 through a lifting structure, a lap plate 4 is arranged at the rear end of the outer wall of the frame 1, and columns 5 that are evenly distributed are fixedly connected to the top of the rotating plate 3, the columns 5 are connected to lifting hollow columns 6 through a height adjustment structure, and a railing assembly 7 is arranged between the lifting hollow columns 6.

[0023] It should be noted that the specific model and specifications of the hydraulic cylinder 8 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated.

[0024] Furthermore, the lifting structure includes a hydraulic cylinder 8, a connecting block 9, and a hinge 10. The hydraulic cylinder 8 is fixedly connected to the top of the rotating block 2, the connecting block 9 is fixedly connected to the outer wall of the rotating plate 3, and one end of the hinge 10 is fixedly connected to the outer wall of the frame 1.

[0025] The connection between the connecting block 9 and the hydraulic cylinder 8 can rotate, and the connection between the hydraulic cylinder 8 and the rotating block 2 can also rotate, so that when the hydraulic cylinder 8 pushes the rotating plate 3 to rise, the angle can be adjusted accordingly to avoid failure to rise.

[0026] Furthermore, the telescopic end of the hydraulic cylinder 8 is fixedly connected to the bottom of the connecting block 9 , and the other end of the hinge 10 is fixedly connected to the rotating plate 3 .

[0027] Among them, the lifting structure is achieved by starting the hydraulic cylinder 8, which pushes the telescopic end upward to drive one end of the rotating plate 3 to move upward. The other end of the rotating plate 3 is connected to the frame 1 through the hinge 10, so that the rotating plate 3 will not leave the position of the frame 1.

[0028] Furthermore, the height adjustment structure includes evenly distributed limit holes 11, limit protrusions 12, sliding holes 13, and springs 14. The limit holes 11 are arranged on the outer wall of the lifting hollow column 6, the limit protrusions 12 are slidably connected to the sliding holes 13, the sliding holes 13 are arranged on the outer wall of the column 5, and the spring 14 is arranged in the sliding holes 13.

[0029] Among them, the column 5 close to the vertical end of the rotating plate 3 is fixedly connected to the rotating plate 3, a sliding groove is opened on the column 5, and a sliding mouth adapted to the sliding groove is also opened on the lifting hollow column 6, so that the lifting hollow column 6 will not be separated from the column 5 when connected to the column 5.

[0030] Furthermore, the limiting hole 11 is slidably connected to the limiting protrusion 12, one end of the spring 14 is fixedly connected to the inner wall of the sliding hole 13, the other end of the spring 14 is fixedly connected to the outer wall of the limiting protrusion 12, and the lifting hollow column 6 is slidably connected to the column 5.

[0031] Among them, the height adjustment structure is to manually press the limit protrusion 12 to make it enter the sliding hole 13 and squeeze the spring 14. When the lifting hollow column 6 is pulled up or down to adjust the height, when it reaches the appropriate position, under the elastic action of the spring 14, the limit protrusion 12 returns to its original position and enters the limit hole 11 to complete the limiting, ensuring that the lifting hollow column 6 will not fall at will.

[0032] Furthermore, the railing assembly 7 includes a uniformly distributed fixed plate 15, a rotating shaft 16, a connecting plate 17, a metal telescopic tube 18, a mounting plate 19, an adapter block 20, and an L-shaped pin 21. The fixed plate 15 is fixedly connected to the outer wall of the lifting hollow column 6 on one side, the rotating shaft 16 is rotatably connected to the inner wall of the fixed plate 15, the connecting plate 17 is fixedly connected to the rotating shaft 16, one end of the metal telescopic tube 18 is fixedly connected to the outer wall of the connecting plate 17, the mounting plate 19 is fixedly connected to the other end of the metal telescopic tube 18, and the adapter block 20 is fixedly connected to the outer wall of the lifting hollow column 6 on the other side.

[0033] Among them, the railing assembly 7 is a railing formed by connecting evenly distributed metal telescopic cylinders 18 with lifting hollow columns 6 on both sides to prevent the falling of goods. Under the action of the metal telescopic cylinders 18, the railing assembly 7 after the restriction is released can be shortened by half, making loading more convenient without taking up space.

[0034] Furthermore, the fixing plate 15 is symmetrically arranged in the upper and lower parts, the outer wall of the connecting plate 17 is slidably connected to the inner wall of the fixing plate 15, the adapter block 20 is vertically symmetrically arranged in the left and right parts, the mounting plate 19 is slidably connected to the inner wall of the adapter block 20, and the L-shaped pin 21 is slidably connected to the mounting plate 19 and the adapter block 20 respectively.

[0035] Among them, the outer walls of the mounting plate 19 and the adapter block 20 are provided with holes that are adapted to the thickness of the L-shaped pin 20, so that the L-shaped pin 20 can be inserted therein to achieve restriction and prevent the railing from detaching during transportation.

[0036] Working principle: First, start the hydraulic cylinder 8, which pushes the telescopic end upward to drive one end of the rotating plate 3 to move upward. The other end of the rotating plate 3 is connected to the frame 1 through the hinge 10, so that the rotating plate 3 will not leave the position of the frame 1, and the rotating plate 3 is therefore more stable when tilting.

[0037] When the lifting frame 6 is lifted up or down, the lifting height is adjusted by pressing the limit protrusion 12 manually, so that it enters the sliding hole 13 and squeezes the spring 14. When the lifting hollow column 6 is pulled up or down to adjust the height, when it reaches the appropriate position, under the elastic action of the spring 14, the limit protrusion 12 returns to its original position and enters the limit hole 11 to complete the limit, ensuring that the lifting hollow column 6 will not fall at will, so that we can adjust the height according to the height of the goods, and have better protection for the goods. Between the lifting hollow columns 6, there are evenly distributed metal telescopic cylinders 18 and the lifting hollow columns 6 on both sides. The railing is connected to form a railing to prevent the goods from falling. Under the action of the metal telescopic cylinder 18, the railing assembly 7 after the restriction is released can be shortened by half, making loading more convenient and not taking up space. When connecting, the L-shaped pin 21 is inserted into the holes of the mounting plate 19 and the adapter block 20. The restriction can be achieved to avoid the falling of the goods, thereby increasing the protection and fixation of the goods on the rotating frame. During the movement, it will not fall easily, which greatly avoids the damage of the goods and greatly reduces the loss of the goods.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
