Since the structure and operation principle of the power roller 21 are prior art, they will not be described in detail herein.

After the goods 10 are located at the preset position of the trolley, in order to avoid the falling of the goods 10 caused by the trolley in the moving process, the trolley further comprises a longitudinal stopping mechanism 3 and a transverse stopping mechanism 4, the longitudinal stopping mechanism 3 can rotate to a stopping position and an avoiding position, when the longitudinal stopping mechanism 3 is located at the stopping position, the longitudinal stopping mechanism 3 can limit the goods 10 to be separated from the trolley along the conveying direction of the driving mechanism 2, and when the longitudinal stopping mechanism 3 is located at the avoiding position, the driving mechanism 2 can drive the goods 10 to enter the trolley or leave the trolley. The transverse stop mechanism 4 is used to limit the cargo 10 from escaping the trolley in a first direction, which is perpendicular to the conveying direction. It should be understood that the conveying direction in this embodiment refers to the direction in which the goods 10 are conveyed by the driving mechanism 2, i.e. the conveying direction of the goods 10 on the trolley, i.e. the arrangement direction of the power roller 21 and the plurality of follower rollers 22, and does not refer to the traveling direction of the trolley.

When the goods 10 need to be placed on the trolley, the longitudinal stopping mechanism 3 rotates to the avoiding position, one end of the goods 10 is placed on one end of the driving mechanism 2, the power roller 21 rotates and drives the follow-up rollers 22 to rotate, and the friction force between the goods 10 and the power roller 21 and between the goods 10 and the follow-up rollers 22 is utilized to convey the goods 10 to the preset position of the trolley. After the goods 10 are transported to the preset position of the trolley, the power roller 21 stops rotating, and the goods 10 also stop at the preset position. The longitudinal stop mechanism 3 is rotated to a stop position, so that the goods 10 are stopped from leaving the trolley by the longitudinal stop mechanism 3 and the transverse stop mechanism 4. After the trolley transports the goods 10 in place, the longitudinal stopping mechanism 3 rotates to the avoiding position, and the power roller 21 and the following roller 22 rotate to convey the goods 10 to leave the trolley.

The trolley provided by the embodiment can enable the goods 10 to be located at the preset position of the trolley through the driving mechanism 2 and transport the goods 10 to leave the trolley, so that an operator does not need to carry the goods 10 on the trolley or unload the goods 10 from the trolley, and the labor intensity of the operator is reduced. The transverse stopping mechanism 4 and the longitudinal stopping mechanism 3 cannot influence the loading of the goods 10 on the trolley, and can stop the goods 10 from leaving the trolley, so that the goods 10 are prevented from falling.

To facilitate transport of the goods 10 by the trolley, casters are also attached to the underside of the frame 1. In order to facilitate the steering of the trolley, the caster comprises a universal wheel 51 and a directional wheel 52, one of the front end of the frame 1 and the rear end of the frame 1 is provided with the universal wheel 51, the other is provided with the directional wheel 52, and the steering of the trolley is realized through the universal wheel 51.

When the longitudinal stopping mechanism 3 is located at the stopping position, the stop lever 32 rotates to the vertical position to stop the goods 10 located on the trolley, and when the longitudinal stopping mechanism 3 is located at the avoiding position, the stop lever 32 rotates to the horizontal position to avoid the goods 10. It will be appreciated that the link 31 is located on the underside of the load 10 provided on the drive mechanism 2 in order not to interfere with the transport of the load 10 on the trolley.

The lateral stop mechanism 4 includes two sets of stop assemblies 41 spaced apart in a first direction to stop the two ends of the cargo 10 in a direction perpendicular to the conveying direction. To avoid the cargo 10 from moving a large distance in the first direction during the transportation of the cargo 10 by the cart, the two sets of stop assemblies 41 preferably abut against the two sides of the cargo 10 or maintain a small distance therebetween. In order to adapt the trolley to cargos 10 with different widths, preferably, two sets of stop assemblies 41 are respectively arranged on the frame 1 in a sliding manner along a first direction so as to be capable of approaching or departing from each other, and cargos 10 with different sizes are placed between the two sets of stop assemblies 41.
