In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.
As shown in fig. 1 to 3, the present disclosure provides a cargo way structure 100, the cargo way structure 100 includes a cargo way 10 and at least one driving assembly 20, the cargo way 10 includes a first shaft 11, a second shaft 12 and a transmission belt 13, the first shaft 11 and the second shaft 12 are fixed, the transmission belt 13 is sleeved on the first shaft 11 and the second shaft 12, the at least one driving assembly 20 includes at least one driving wheel 21, the driving wheel 21 is engaged with the first shaft 11 to construct a friction pair with the transmission belt 13, so that the driving wheel 21 can drive the transmission belt 13 to move.
In the cargo way structure 100 provided by the present disclosure, the driving wheel 21 cooperates with the first shaft 11 in the process of rotating around its own axis, so as to press the transmission belt 13 located therebetween, and provide friction force to the transmission belt 13 to drive the transmission belt 13 to rotate, thereby enabling the transmission belt 13 to transport cargo, as shown in fig. 1.
The friction type transmission provided by the present disclosure does not require the driving assembly 20 to be provided on the lane 10, that is, the lane 10 itself does not require the driving assembly 20, which is advantageous to simplify the structure of the lane 10, compared to the push plate type and the conveyor belt type in the related art. Moreover, the driving wheel 21 is adopted to directly drive the transmission belt 13 through friction transmission, so that a transmission part between the driving wheel and the transmission belt is omitted, and the transmission belt 13 can run efficiently and stably.
In addition, in a limited space, since parts such as power parts (such as motors) do not need to be arranged on two sides of the width direction of the conveying belt 13 like the existing structure, the conveying surface of the conveying belt 10 is favorably increased, and the space utilization rate of the cargo path structure 100 is favorably improved.
It is to be understood, however, that the first shaft 11 and the second shaft 12 may be secured to suitable components based on the environment in which the cargo way 10 is to be used, and the present disclosure is not limited thereto. For example, when the raceway 10 is used with a container, the first shaft 11 and the second shaft 12 may be fixed to the side plates of the container, respectively.

The rotating wheels (the driving wheels and the driven wheels) are arranged on the upper side and the lower side of the first shaft 11 or the second shaft 12, so that the uniformity of stress on the upper side and the lower side of the first shaft 11 or the second shaft 12 is facilitated, and the stability of conveying goods by a goods way structure is facilitated to be kept.
In order to ensure that the driving wheel 21 can provide sufficient friction force to the conveyor belt, optionally, in an embodiment of the present disclosure, the width of the driving wheel 21 may be equal to the width of the conveyor belt 13 to increase the contact area of the driving wheel 21 and the conveyor belt 13 as much as possible, so as to increase the friction force as much as possible to ensure the reliability of the friction transmission.
It should be noted that the present disclosure does not limit the relationship between the width of the driving wheel 21 and the width of the conveying belt 13. In other embodiments, the width of the drive wheel 21 may be less than the width of the conveyor belt 13 or greater than the width of the conveyor belt 13.

Like this, through a plurality of pits and a plurality of protruding cooperation, do benefit to the coefficient of friction that increases both to be favorable to improving the frictional force between drive wheel 21 and the transmission band 13, thereby promote friction drive's reliability.
As shown in fig. 1 and 2, in one embodiment of the present disclosure, the driving assembly 20 further includes a bracket 22, the driving wheel 21 is rotatably mounted to the bracket 22, and the bracket 22 is configured to be able to move away from or close to the transmission belt 13 so that the driving wheel 21 drives the transmission belt 13 or stops driving the transmission belt 13. Specifically, when goods are to be transported, the mounting bracket 22 may be brought into position adjacent the conveyor belt 13 and the drive wheel 21 and the corresponding shaft (e.g., the first shaft 11 shown in fig. 1) may be caused to press against the conveyor belt 13 therebetween. Thus, when the driving wheel 21 rotates, the driving wheel 21 provides a driving friction force to the transmission belt 13, and the transmission belt 13 is moved by the friction force. When it is desired to stop the movement of the conveyor belt 13, the mounting bracket 22 can be moved away from the conveyor belt 13 to a position to remove the pressing force of the driving wheel 21 and the conveyor belt 13, thereby removing the driving friction and stopping the movement of the conveyor belt 13.
Based on this, since the driving unit 20 can be away from the cargo path 10, when it is detected that the cargo falls off one end (left end in the direction of the drawing shown in fig. 2) of the conveyor belt 13 during the conveyance of the cargo by the conveyor belt 13, the rotation of the driving wheel 21 is stopped, and the application of the friction force to the conveyor belt 13 is stopped, so that the movement of the conveyor belt 13 is stopped. At this time, the support 22 may be moved away from the lane 10 to load the lane 10 from the other end (right end in the drawing direction shown in fig. 2) of the conveyor belt 12. In addition, when there is more than one lane 10 and there is a need to transfer goods in other lanes 10, the driving assembly 20 can be moved to other lanes 10 to drive the corresponding lane 10 to transfer goods.
In one embodiment of the present disclosure, the cargo way structure may include a plurality of cargo ways 10, and corresponding ends (i.e., ends having the same direction) of the plurality of cargo ways 10 share one driving assembly 20, so as to save the number of driving assemblies 20 and save cost.

This support 22 simple structure, moreover, because two drive wheels 21 are installed respectively in two frames, to support 22, when two drive wheels 21 rotated, support 22's equilibrium was better than the technical scheme who sets up two drive wheels 21 simultaneously in the frame of same side.
To facilitate avoiding the conveyor belt and the first shaft 11 or the second shaft 12, and to reduce the overall weight of the frame 22, as shown in fig. 1 and 2, in one embodiment of the present disclosure, the first side frame 221 and the second side frame 222 may have a height dimension smaller than that of the end frame 223, and the first side frame 221 may be connected to a lower portion of one end of the end frame 223, and the second side frame 222 may be connected to an upper portion of the other end of the end frame 222.

In this way, when the driving assembly 20 is moved to act on the conveyor belt 13 of another lane 10, it can act directly on another lane 10. Therefore, the solution of the present embodiment is advantageous in reducing the number of driving mechanisms used, compared to the solution in which the driving mechanism is provided separately for each lane 10.
