When unloading, the goods need to be pushed forward so that part of the goods are suspended in the air, so that the unloading personnel can find a fulcrum for unloading, but the suspended goods are in an unstable state and are prone to overturning, causing injuries to the unloading personnel, and repeated attempts to find a suitable fulcrum will also waste a lot of time.

[0004] Therefore, it is necessary to provide a low-flatbed transport semi-trailer with an anti-slip structure, which increases the friction between the anti-slip structure and the cargo through anti-slip pads, and lifts the cargo during unloading through components such as lifting plates, inclined blocks and electric push rods, making unloading easier. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned existing patents, when unloading, the goods need to be pushed forward so that part of the goods are suspended in the air so that the unloading personnel can find a fulcrum to unload. However, the suspended goods are in an unstable state and are prone to overturning, causing injuries to the unloading personnel. Repeated attempts to find a suitable fulcrum will also waste a lot of time. The utility model provides a low-flat transport semi-trailer with an anti-slip structure. The anti-slip pad is used to increase the friction between the anti-slip structure and the goods. The lifting plate, inclined block and electric push rod and other components are used to lift the goods during unloading to facilitate unloading.

[0006] To solve the above problems, the utility model adopts the following technical solutions: a low-flat transport semi-trailer with an anti-slip structure, comprising a base plate, a moving component, a connecting frame and a baffle, two moving components are rotatably arranged on the base plate, a connecting frame is fixedly connected to the base plate, a baffle is slidably arranged on the connecting frame, and also comprises a lifting plate, an inclined block, an electric push rod, a contact block and an anti-slip pad, a lifting plate is slidably arranged on the connecting frame, two inclined blocks are fixedly connected to the lifting plate, the inclined block passes through the connecting frame, an electric push rod is installed on the base plate, a contact block is installed on the telescopic rod of the electric push rod, the contact block is located in front of the inclined block, and a plurality of anti-slip pads are embedded on the lifting plate.

[0010] In a preferred embodiment of the present invention, a protective shell is further included. The protective shell is fixedly connected to the bottom plate, and the electric push rod, the contact block and the inclined block are located in the protective shell.

[0011] In a preferred embodiment of the present invention, a protective pad is further included, and the hanging ring is provided with the protective pad.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. The anti-slip pad is used as an anti-slip structure to increase the friction of the goods. When the goods need to be unloaded, the telescopic rod of the electric push rod contracts and drives the contact block to move to the right to contact the inclined block, so that the contact block lifts the inclined block, and the inclined block drives the lifting plate and the goods to move upward, so that a gap appears between the lifting plate and the connecting frame, which makes it easier for unloading personnel to find a fulcrum and reduces the groping time required for unloading. The goods are still in a flat state, which enhances the safety of unloading.

[0013] 2. By starting the dual-axis motor, the output shaft of the dual-axis motor drives the two screws to rotate, so that the two screws drive the two sliding blocks and the telescopic plate to move toward each other, so that the goods can be fixed and limited, thereby preventing the goods from deviating during transportation and hitting the frame wall, thereby avoiding damage to the goods.

[0014] 3. By pulling out the hanging rope, the winding wheel and the rotating shaft rotate, and the spiral spring is deformed accordingly. Then the hanging rope is hooked on the hanging ring on the other side, so that the hanging rope can further fix the goods in the connecting frame, thereby further preventing the goods from moving or slipping during transportation and ensuring the safety of the goods.

The contact block 8 is installed on the telescopic rod of the electric push rod 7. The contact block 8 is located in front of the oblique block 6. Eight anti-slip pads 9 are embedded on the top of the lifting plate 5. The anti-slip pad 9 is an anti-slip structure.

[0026] See Figure 5 As shown, a protective shell 22 is also included. The bottom of the base plate 1 is provided with the protective shell 22 by welding. The protective shell 22 is used to protect the electric push rod 7, the contact block 8 and the inclined block 6.

[0027] When it is necessary to use a low-bed transport semi-trailer to transport goods, the goods are placed in the connecting frame 3. The anti-slip pad 9 is an anti-slip structure, which can increase the friction of the goods. When the goods need to be unloaded, the electric push rod 7 is started, and the telescopic rod of the electric push rod 7 contracts to drive the contact block 8 to move to the right and contact the inclined block 6, so that the contact block 8 lifts the inclined block 6, and the inclined block 6 drives the lifting plate 5 and the goods to move upward, so that a gap appears between the lifting plate 5 and the connecting frame 3, which makes it easier for the unloading personnel to find the fulcrum and exert force, reducing the groping time required for unloading, and the goods are still in a flat state, enhancing the safety of unloading.
