[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, drive cavities can be provided on the front and rear sides inside the vehicle body. After starting the motor on one side inside the drive cavity, the motor will cause the double-threaded drive rod to rotate. The rotation of the double-threaded drive rod will cause the two first moving blocks to drive the baffle to move in opposite or approaching directions.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1-5 The utility model provides a technical solution: a combined molten steel transfer trailer assembly, including a body 1, a mounting portion 2 is provided on one side of the body 1, a lifting portion 3 is installed on one side of the front side of the upper end of the body 1, a transmission cavity 4 is provided on the front and rear sides of the body 1, a double-threaded transmission rod 6 is rotatably provided inside the transmission cavity 4, two buffer cavities 10 are provided on the front and rear sides of the mounting portion 2, and the interior of the buffer cavity 10 is filled with shock-absorbing silicone oil, and two slide grooves 15 are provided at the lower end of the mounting portion 2, and sliders 17 are slidably provided on both sides of the slide groove 15.

[0025] When in use, the lifting task is performed by connecting the mounting part 2 with the front of the vehicle and utilizing the lifting part 3 on the vehicle body 1. After the motor 5 is started, it drives the double-threaded transmission rod 6 to rotate, and the two moving blocks 7 slide on the first guide rod 9 to achieve opposite or opposite linear movement, thereby flexibly adjusting the position of the baffle 8 to adapt to loading of goods of different lengths. The operation is simple and flexible. During driving, the first buffer plate 14 drives the lifting plate 11 to move under the guidance of the second guide rod 12 through the connecting rod 13, squeezing the shock-absorbing silicone oil in the buffer cavity 10 to achieve preliminary buffering. At the same time, the vibration of the second buffer plate 20 is transmitted to the slider 17 through the connecting block 19, sliding on the third guide rod 16 and stretching or compressing the buffer spring 18, and utilizing the elasticity of the spring to further absorb the vibration energy, reduce the vibration amplitude of the mounting part 2, ensure driving stability, and enhance the durability and safety of the overall structure.

[0026] See also Figure 1, on one side inside the transmission cavity 4, there is a motor 5, and the output end of the motor 5 is drivingly connected to the double-threaded transmission rod 6 through a coupling. The power of the motor 5 can be efficiently and stably transmitted to the double-threaded transmission rod 6 to drive its rotation, providing strong power support for the subsequent position adjustment of the moving block 7 and the baffle 8;

[0027] Please refer to Figure 1 , on both sides of the outside of the double-threaded transmission rod 6, there are moving blocks 7 threadedly connected. At the upper ends of the moving blocks 7, there are baffles 8, and one end of each baffle 8 extends to the outside of the transmission cavity 4. Below the double-threaded transmission rod 6, there is a first guide rod 9. The first guide rod 9 passes through the moving blocks 7, and the first guide rod 9 and the moving blocks 7, through the rotation of the double-threaded transmission rod 6, can drive the two moving blocks 7 to perform synchronous but opposite-direction linear movements under the guidance of the first guide rod 9, thus realizing the flexible adjustment of the position of the baffle 8 to meet different cargo loading requirements;

[0028] Please refer to Figure 4 , at the four corners inside the buffer cavity 10, there are second guide rods 12 welded. Inside the buffer cavity 10, there is a lifting plate 11. The second guide rods 12 pass through the lifting plate 11, and the second guide rods 12 are in sliding fit with the lifting plate 11. The second guide rods 12 can ensure that the lifting plate 11 moves smoothly and without deviation inside the buffer cavity 10, providing a stable support platform for the subsequent buffering action and improving the stability of the overall structure at the same time;

[0029] Please refer to Figure 3 and Figure 4 , below the buffer cavity 10, there is a first buffer plate 14. At the lower end of the lifting plate 11, there is a connecting rod 13 adhesively fixed, and one end of the connecting rod 13 passes through and extends to the outside of the buffer cavity 10. The end of the connecting rod 13 located outside the buffer cavity 10 is connected to the first buffer plate 14. Through the movement of the lifting plate 11, it can drive the connecting rod 13 and the first buffer plate 14 to perform buffering actions, effectively absorbing external impact forces and improving the seismic performance of the overall structure;

[0030] Please refer to Figure 4 and Figure 5 , inside the sliding groove 15, there is a third guide rod 16 welded. The third guide rod 16 is sleeved with sliders 17, and the third guide rod 16 is in sliding fit with the sliders 17. On both sides of the outside of the third guide rod 16, there are buffer springs 18 sleeved. One end of each buffer spring 18 is connected to the slider 17, and the other end of each buffer spring 18 is connected to the sliding groove 15. It can ensure that the sliders 17 slide smoothly inside the sliding groove 15. At the same time, by using the elastic recovery effect of the buffer springs 18, the sliders 17 and the connected components are buffered and protected, reducing vibration and impact and improving the stability and durability of the overall structure;

[0031] Please refer to Figure 3 ,Figure 4 and Figure 5 A second buffer plate 20 is arranged directly below the slider 17. The second buffer plate 20 and the slider 17 are connected by a connecting block 19, and the connecting block 19 is rotatably connected to the second buffer plate 20 and the slider 17. The rotatable connection of the connecting block 19 can ensure that when the second buffer plate 20 is subjected to an external impact force, it can smoothly drive the slider 17 to slide on the third guide rod 16 and compress the buffer spring 18 for buffering, further improving the seismic performance and stability of the overall structure.

[0032] Working principle: During use, the installation part 2 is connected to the vehicle head. Through the lifting part 3 on the vehicle body 1, daily lifting operations can be carried out. Start the motor 5, and the double-threaded transmission rod 6 can be rotated through the transmission connection of the coupling. The double-threaded transmission rod 6 will drive the two moving blocks 7 to rotate synchronously. Since the moving blocks 7 are all slidably engaged with the first guide rod 9, the rotation of the two moving blocks 7 will be converted into opposite or approaching horizontal linear movements. By controlling the distance between the two moving blocks 7, the adjustment of the baffle 8 can be realized, and thus different lengths of goods can be adapted, and the operation is simple and convenient. When the vehicle head drives the installation part 2 to move, both the first buffer plate 14 and the second buffer plate 20 are in contact with the upper end of the vehicle head. The first buffer plate 14 will cause the remaining movement of the lifting plate 11 through the connecting rod 13. The lifting plate 11 will be guided by the second guide rod 12 to avoid deviation in direction and affect the buffering effect. When the lifting plate 11 moves, it will squeeze the shock-absorbing silicone oil filled in the buffer cavity 10, and thus the lifting plate 11 can be buffered through the compression elasticity of the shock-absorbing silicone oil, and then the buffering of the first buffer plate 14 can be realized, making the installation of the installation part 2 more stable. At the same time, when the second buffer plate 20 is driven by the vehicle head to vibrate, it will cause the slider 17 to slide on the third guide rod 16 through the connecting block 19 to avoid deviation in direction. When the slider 17 slides, the buffer spring 18 will be stretched or compressed, and thus the buffering of the second buffer plate 20 can be realized through the elastic recovery effect of the buffer spring 18, further reducing the amplitude of vibration of the installation part 2 and further improving the stability after installation.
