the conveyor belt 31 is used for transferring the target piece on the present conveying vehicle to other conveying vehicles, or is used for butting with the conveyor belt 31 on other conveying vehicles so as to complete the conveying of the target piece.

The transmission vehicle provided by the embodiment of the application at least has the following technical effects:

through the transmission car that this application embodiment provided, when this transmission car conveys the target piece in the goods way, other transmission cars also have the task of conveying the target piece in this goods way, position information through other transmission cars of first position sensor response, rotate through first driving motor drive wheel 2, and then make this transmission car travel, this transmission car is according to the position information of other transmission cars and is gone to the position department of other transmission cars, drive conveying axle 32 through the second driving motor and rotate, and then drive the conveyer belt 31 of being connected with conveying axle 32 and rotate, the goods that will be located on conveyer belt 31 convey other transmission cars, with the conveying of accomplishing the target piece. The flat plate is arranged on the top of the vehicle body 1 along the horizontal direction, and the conveyor belt 31 is arranged on the flat plate, so that the stability of goods on the conveyor belt 31 can be ensured; by setting the length of the conveyor belt 31 to be greater than or equal to the length from the first side to the second side, the length of the flat plate can be prevented from influencing the butt joint of the conveyor belt 31 on the conveying vehicle and the conveyor belts 31 on other conveying vehicles.

The transport vehicle provided by the embodiment of the present application will be further described below by way of alternative embodiments.

It should be noted that, according to the transporting vehicle provided in the embodiment of the present application, when the transporting vehicle transports the goods alone, the conveyor belt 31 does not need to transport, that is, the conveyor belt 31 is in a static state, and the transporting vehicle transports the goods alone. When the conveying vehicle conveys the goods in the first task, other tasks need to be executed by the conveying vehicle, if the conveying vehicle conveys the goods in the first task again, the conveying time can be prolonged, at the moment, the conveying vehicle can be butted with the conveying belts 31 on other conveying vehicles through the conveying belts 31 on the other conveying vehicles, namely, the conveying belts 31 on the conveying vehicle and the conveying belts 31 on other vehicles run at the moment, and the conveying of the goods is completed. Or when this transmission car position in the gap between a plurality of goods shelves, this gap can only allow a transmission car operation, when other transmission cars need get through the gap between the above-mentioned goods shelves and put the goods, this moment, the conveyer belt 31 motion on this transmission car transmits the goods on other transmission cars for conveyer belt 31 on this transmission car, accomplishes the conveying of this goods through this transmission car. Or by the butt joint of the conveyor belts on a plurality of conveying vehicles, see fig. 2, to form a conveying chain, and the conveying of the goods is completed. Thus, the time for transporting the goods is saved.

In one possible implementation, as shown in fig. 3, the vehicle body 1 includes: an upper vehicle body 11 and a lower vehicle body 12. The plate is disposed on top of the upper body 11 and the wheels 2 are disposed on the bottom of the lower body 12. The lower vehicle body 2 is dimensioned so as not to interfere with the abutment of the conveyor belt 31 on the upper vehicle body 11 with the conveyor belts 31 on the other transport vehicles.

It can be understood that when the belt 31 of the present transporting vehicle is butted against the belt 31 of the other transporting vehicle, if the dimension of the lower vehicle body 2 of the transporting vehicle in the direction of the belt 31 is larger than the dimension of the upper vehicle body 11, the butting between the belts 31 of the upper vehicle bodies 11 of the plurality of transporting vehicles is affected.

As an example, when the conveyor belt 31 is disposed in the front-to-rear direction, the length of the lower vehicle body 2 along the front-to-rear direction needs to be not greater than the length of the upper vehicle body 11 along the front-to-rear direction to ensure the butt joint of the conveyor belt 31 between the plurality of transport vehicles.

As another example, when the conveyor belts 31 are arranged in a direction perpendicular to the head and the tail, the length of the lower vehicle body 2 in the direction perpendicular to the head and the tail is not greater than the length of the upper vehicle body 11 in the direction perpendicular to the head and the tail so as not to affect the butt joint of the conveyor belts 31 on the plurality of transport vehicles.

In one possible implementation, as shown in fig. 4, the transport vehicle further includes: a first baffle 13 and a second baffle 14;

the first baffle 13 and the second baffle 14 are arranged oppositely, the conveyor belt 31 is positioned between the first baffle 13 and the second baffle 14, and the first baffle 13 and the second baffle 14 are arranged along the moving direction of the conveyor belt 31.

It can be understood that, when the transportation of the goods is completed individually by the transportation vehicle, the conveyor belt 31 does not operate, and the goods are placed on the conveyor belt 31, so that the goods are prone to collapse or fall down, which results in damage to the goods and affects the quality of the goods. Through first baffle 13 and second baffle 14 that this application embodiment provided, first baffle 13 sets up with second baffle 14 relatively, and conveyer belt 31 sets up between first baffle 13 and second baffle 14, and first baffle 13 is configured as not influencing the butt joint of conveyer belt 31 on this transmission car with conveyer belt 31 on other transmission cars, so, guaranteed the safety of goods promptly, also do not influence the butt joint of goods between a plurality of transmission cars.

As an example, when the conveyor belt 31 is disposed in the vehicle front-to-vehicle rear direction, the first and

second fences

13, 14 may be disposed in a direction coincident with the vehicle front and vehicle rear. When the conveyor belt 31 is disposed in a direction perpendicular to the head and tail of the vehicle, the first and

second fences

13, 14 may be disposed on both sides of the head or tail of the vehicle. Therefore, the butt joint of the conveying vehicle and the conveying belts 31 on other conveying vehicles cannot be influenced.

The first baffle 13 that this application embodiment provided and the material of second baffle 14 can be the baffle of stainless steel material, so, can improve the intensity and the hardness of first baffle 13 and second baffle 14. The material of the first baffle 13 and the second baffle 14 can also be determined according to the material of the upper vehicle body 11 and the lower vehicle body 2 of the conveying vehicle, so that the connection stability between the first baffle 13, the second baffle 14 and the upper vehicle body 11 can be improved.

The lengths of the first and

second flaps

13 and 14 may be determined according to the length of the upper vehicle body 11, but cannot be greater than the length of the conveyor belt 31 so as not to affect the efficiency of the docking between the plurality of conveyor belts 31 and the conveyance of goods.

The first baffle 13 and the second baffle 14 can be detachably connected with the upper vehicle body 11, for example, bolted connection or clamped connection. Thus, the first shutter 13 and the second shutter 14 can be detached as needed. For example, when the length of the cargo to be transported is greater than the length of the upper vehicle body 11, the first barrier 13 and the second barrier 14 need to be detached, and the transportation of the cargo is completed. Or when the state and size of the goods to be transported are different, the heights of the first and

second barriers

13 and 14 may be adjusted according to the state and size of the goods.
