It solves the problem that the existing freight trailers are generally simple in structure and cannot lift and lower cargo, resulting in the need to rely on manpower or forklifts to load and unload cargo, which is more laborious and troublesome, and reduces the flexibility and practicality of the freight trailer.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a freight trailer lifting device, comprising a bracket, a hydraulic cylinder is fixedly connected to the inside of the bracket, the top of the hydraulic cylinder is fixedly connected to a fixing frame, the bottom surface of the fixing frame is fixedly connected to a lifting plate, the outer surface of the bracket is fixedly connected to four top plates, each of the top plates has a sliding rod slidably inserted inside, the bottom surface of the sliding rod is fixedly connected to a bottom plate, and one side of the bottom plate is rotatably connected to a roller.
[0006] Through the above scheme, since the existing freight trailer structure is generally simple and cannot perform lifting operations on the goods, it is necessary to rely on manpower or forklifts to load and unload the goods, which is more laborious and troublesome, and reduces the flexibility and practicality of the freight trailer. By setting up hydraulic cylinders, fixed frames and lifting plates, the goods can be lifted and lowered during loading and unloading, which reduces the workload of workers and facilitates the loading and unloading operations of the goods. By setting up springs and dampers, the goods are buffered and shock-absorbed during transportation, thereby increasing the stability of cargo transportation.
[0007] Furthermore, four columns are fixedly connected to the upper surface of the bracket, a ring is slidably sleeved on the outer circumference of each column, a connecting plate is fixedly connected to the outer circumference of each ring, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the lifting plate.
[0008] Through the above scheme, the lifting plate is reinforced, so that the lifting plate follows the ring to always perform longitudinal lifting and lowering, thereby increasing the stability of the lifting plate movement.
[0009] Furthermore, a guardrail is fixedly connected to the upper surface of the bracket, and a baffle is rotatably connected to the front surface of the bracket.
[0010] Through the above solution, the goods on the lifting platform are protected to prevent the goods on the lifting platform from tilting and falling, thereby preventing the goods from being damaged.

[0012] Through the above solution, the baffle is restricted by the positioning plate to prevent the baffle from being opened easily.
[0013] Furthermore, a resistance sheet is fixedly sleeved on the outer circumferential surface of the rotating rod, and the outer circumferential surface of the resistance sheet is rotatably connected to the inside of the bracket.
[0014] Through the above scheme, the rotating rod is restricted to prevent it from sliding off, and at the same time, resistance is applied between the rotating rod and the bracket to prevent the positioning plate from rotating easily, causing the baffle to lose the restriction of the positioning plate and open easily.
[0015] Furthermore, a spring is fixedly connected to the upper surface of the bottom plate, the top end of the spring is fixedly connected to the bottom surface of the top plate, a damper is fixedly connected to the upper surface of the bottom plate, and the upper surface of the damper is fixedly connected to the bottom surface of the top plate.
[0016] Through the above scheme, the cargo is buffered and shock-absorbed by springs and dampers, thereby increasing the stability of the cargo during transportation.
[0017] Furthermore, the outer circumferential surface of the sliding rod is fixedly connected to a limiting plate, and the outer surface of the limiting plate is slidably connected to the inside of the top plate.
[0018] Through the above solution, the sliding rod is restricted to prevent the sliding rod from rotating, thereby increasing the stability of the sliding rod movement.
[0019] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of the sliding rod, and a second limiting ring is fixedly sleeved on the outer circumferential surface of the column.
[0020] Through the above solution, the first limiting ring is used to prevent the top plate and the slide rod from easily slipping off, and the second limiting ring is used to prevent the sleeve ring from easily falling off from the column.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] The freight trailer lifting device enables the goods to be lifted and lowered during loading and unloading by arranging a hydraulic cylinder, a fixing frame and a lifting plate, and cushions and reduces shocks during the transportation of the goods by arranging a spring and a damper, thereby reducing the workload of workers, facilitating the loading and unloading of the goods, and increasing the stability of the transportation of the goods. The device solves the problem that the existing freight trailer cannot lift the goods, resulting in the need to rely on manpower or forklifts to load and unload the goods, which is laborious and troublesome, and reduces the flexibility and practicality of the freight trailer.

By providing a spring 18 and a damper 19, the goods are buffered and shock-absorbed during transportation, thereby reducing the workload of workers, facilitating the loading and unloading of goods, and increasing the stability of cargo transportation. This solves the problem that existing freight trailers cannot lift goods, resulting in the need to rely on manpower or forklifts to load and unload goods, which is more laborious and troublesome, and reduces the flexibility and practicality of freight trailers.
[0040] It should be noted that the upper surface of the lifting plate 4 is provided with anti-skid grooves arranged at equal distances to prevent the goods on the lifting plate 4 from sliding easily, thereby increasing the stability of the goods during transportation.
[0041] The working principle of the above embodiment is:
[0042] The hydraulic cylinder 2 can be started to drive the lifting platform 4 to rise and fall through the fixed frame 3. When the cargo needs to be loaded and unloaded, the baffle 9 is opened first, and then the lifting platform 4 is lowered to the height of the ground, and then the cargo is placed on the lifting platform 4. After the lifting platform 4 is lifted to a certain height, the baffle 9 is closed, and the positioning plate 12 is rotated to the position of the support block 10. After the baffle 9 is positioned, the transportation operation can be carried out. The spring 18 and the damper 19 can buffer and reduce the shock of the cargo during transportation, increase the stability of the cargo during transportation, and the guardrail 8 and the baffle 9 can protect the cargo to prevent the cargo from tipping over and falling.
