[0039] Among them, when a flatbed transport vehicle of the utility model is transferring goods, a certain amount of goods are piled on the top plate 5000 and the transportation is started. At this time, the power supply component supplies power to the control box component, and the control box controls the driving component 1200 to rotate, so that the vehicle as a whole runs along the route set by the controller. At the same time, the sensor component on the chassis frame 1100 works to detect the surrounding environment at all times. If an obstacle is found on the set road, the sensor component can promptly feedback to the controller and turn off the driving component 1200 and notify the maintenance personnel to clear the obstacle. When the vehicle arrives at the transfer area, the vehicle stops and waits to transfer the goods on the top plate 5000 to the transport track. When the sensor component measures the height position of the transport track for transfer and transmits the measured value to the control box component, the control box component controls the lifting component 2000 to lift the top plate to the measurement position according to the measured value, and starts the transverse movement component 6000 after reaching the measurement position to transfer the goods on the top plate to the transport track. When the sensor component on the top plate 5000 cannot detect the goods, the sensor component will send a transfer completion signal to the control box component. At this time, the control box component controls the lifting component 2000 to lower the top plate 5000. After the top plate 5000 is lowered, the control box component controls the driving component 1200 to move and install the original set route back to the initial position, waiting for the next transfer.

A driven gear 6110 is provided, and a plurality of transport chains 6700 that transmit transmission to each other are provided on the main transmission component 6100, the secondary transmission component 6200 and the auxiliary transmission component 6300. The transverse motor 6500 is arranged on the top plate 5000 close to the auxiliary transmission component 6300. The output end of the transverse motor 6500 is connected to the input end of the reducer 6400. The output end of the reducer 6400 is connected to the driven gear 6110 through a chain. The tensioner 6600 is arranged on the chain that transmits transmission to each other between the reducer 6400 and the driven gear 6110. When transferring goods laterally, the transverse movement motor 6500 is started to drive the reducer 6400 to rotate, and the reducer 6400 drives the driven gear 6110 of the main transmission component 6100 to rotate, so that the main transmission component 6100 rotates, and drives the secondary transmission component 6200 to rotate through multiple transport chains 6700, so that the goods on the transport chain 6700 are moved laterally, wherein the auxiliary transmission component 6300 is used to press the transport chain 6700 to prevent the transport chain 6700 from loosening.

[0043] Further, such as Figure 1 and Figure 2 As shown, the sensing component includes an obstacle avoidance component 7100, a height determining component 7200 and a position determining component 7300, wherein the obstacle avoidance component 7100 is arranged on the chassis frame 1100, the position determining component 7300 is arranged on the top surface of the top plate 5000, and the height determining component 7200 is arranged on the anti-collision frame 4100, and the obstacle avoidance component 7100, the position determining component 7300 and the height determining component 7200 are all connected to the control box component.

The obstacle avoidance component 7100 is arranged on the chassis frame 1100 to perform obstacle avoidance detection and navigation guidance respectively to ensure the stable operation of the trolley. At the same time, the height determination component 7200 is used to detect the position of the transport track, so that the lifting component 2000 lifts the top plate 5000 to the corresponding height, which is convenient for the lateral transfer of the goods on the top plate 5000, and the position determination component 7300 is used to detect whether there is goods on the top plate 5000 and the transportation status of the goods during the lateral transfer.

The guide rods 8100 cooperate with the guide sleeves 8200. The other end of the guide rods 8100 extends into the guide sleeves 8200. When the lifting assembly 2000 lifts the top plate 5000, the guide rods 8100 are lifted together with the top plate 5000, so that the guide rods 8100 perform a linear vertical motion in the guide sleeves 8200 to assist the top plate 5000 to lift. When the lifting assembly 2000 lowers the top plate 5000, the guide rods 8100 assist the top plate 5000 to return to the initial position.

[0045] Further, such as Figure 6 As shown, the flatbed transport vehicle also includes a clamping assembly, which is arranged on the chassis frame 1100.

When the trolley crosses the speed bump on the road, the center of gravity of the trolley will deflect to a certain extent. At this time, the cargo on the top plate of the trolley will deviate with the center of gravity, resulting in cargo falling. At this time, a clamping component is set to clamp the cargo on the top plate to prevent the cargo from falling from the top plate.

[0046] The working principle of the clamping assembly is as follows: when the goods are transferred to the top plate, the position determining component 7300 detects whether the loading of the goods on the top plate is completed. After the loading is completed, the signal is transmitted to the control box component. The control box component controls the motor movement of the linkage component 9300, so that the gear at the output end of the motor rotates counterclockwise, thereby controlling the first rack 9400 and the second rack 9500 to retract inward. At this time, the first clamping plate 9100 and the second clamping plate 9200 change from an open state to a tightened state, thereby clamping the goods on the top plate. The clamping assembly is always in a working state during the operation of the trolley. When the trolley reaches the transfer area, the clamping assembly returns to the initial state, and the first clamping plate 9100 and the second clamping plate 9200 are restored from a tightened state to an open state.
