[0024] Please refer to Figure 1 to Figure 2 , Figure 1 A schematic diagram of the structure of a driving unit in an embodiment of the present invention; Figure 2 It is a partial schematic diagram of a container transportation system in one embodiment of the present invention.

[0025] The present invention provides a rail vehicle and a container transportation system thereof. The rail vehicle in this article can be used to transport containers, and has a carrying platform for loading containers. The specific structure of the rail vehicle is not described in detail herein, and reference may be made to the prior art.

[0026] The container transportation system provided by the present invention is arranged inside the carriage, and includes a detection component 30, a supporting wheel system and a driving wheel system; the detection component 30 is used to detect the container position signal; the detection component 30 can be a contact detection component 30 or a non-contact detection component 30. It is preferred that the detection component 30 is a non-contact detection component 30, such as an inductive sensor.

[0027] The support wheel system in the present invention includes a plurality of driven support wheels and a support shaft, and each driven support wheel is rotatably supported on the carriage through a corresponding support shaft. In order to facilitate the arrangement and transportation of containers, the support wheel system may include a plurality of support units, each support unit includes at least one driven support wheel, and the driven support wheel is rotatably supported on a driven support, and the driven support is installed on the carriage. This can facilitate the arrangement of the support wheel system. The support wheel system may include two or more support units 200, each support unit includes a support seat and at least one driven support wheel, and the driven support wheel is rotatably arranged on the support seat. The support seat is fixed in cooperation with the carriage floor.

[0028] The driving wheel system includes a driving wheel 20 and a driving device. The driving device drives the driving wheel 20 to rise and fall and rotate around the corresponding installation axis according to the container position signal. The driving device can change the height position of the driving wheel 20 and can also drive the driving wheel 20 to rotate to provide power for the container to run in the carriage.

[0029] When the container transportation system provided by the present invention is used, when the detection component 30 detects that the container moves to a predetermined position, the driving device drives the driving wheel 20 to rise to a height that matches the bottom of the container, and drives the driving wheel 20 to rotate to provide power for the container to move. When the container passes, the driving device drives the driving wheel 20 to return to the initial height position. The driven wheel in the supporting wheel system plays a driven supporting role during the movement of the container.

[0030] Under normal conditions, the driving wheel 20 is in an initial position, which is lower than the contact position with the bottom wall of the container. Thus, by reasonably setting the number and position of the driving wheels 20, the container can be transported in different directions, thereby improving the flexibility of container transportation.

[0031] The driving device can directly drive the driving wheel 20 to move up and down, and of course, can also directly drive the mounting seat of the driving unit. The following embodiment provides an implementation method in which the driving device drives the mounting seat of the driving unit to move to achieve the lifting of the driving wheel 20.

[0032] In a specific embodiment, the driving wheel system may include a plurality of driving units 100, each driving unit includes a mounting seat 10, at least one driving wheel 20 and a driving component, the driving wheel 20 is rotatably mounted on the mounting seat 10, and the driving component drives the mounting seat 10 to rise and fall and drives each driving wheel 20 to rotate; a detection component 30 is installed on the mounting seat 10 of each driving unit.

[0033] In this embodiment, the driving wheel system is configured as a plurality of independent driving units to achieve modular configuration. The driving units are independent of each other and do not affect each other. The configuration is convenient and the working reliability is high.

[0034] Furthermore, one end of the mounting seat 10 is rotatably connected to the carriage via a hinge shaft 40, and each driving wheel 20 is mounted on the other end of the mounting seat 10, and the driving component drives the mounting seat 10 to reciprocate around the rotation axis.

[0035] The driving component can be a motor or a power component such as a cylinder.

[0036] In this specific embodiment, the driving component may include a motor and a cam structure 50, the cam structure 50 includes a cam seat 51 and a cam 52 rotatably set on the cam seat 51, the cam seat 51 has a structure that is fixed with the floor of the vehicle body, and the motor drives the cam 52 to rotate so that the other end of the mounting base 10 reciprocates around the hinge shaft 40.

[0037] That is, the cam seat 51 can be installed at a predetermined position of the floor of the vehicle compartment, and the motor can be installed on the mounting seat, and the motor drives the cam 52 to rotate to adjust the height position of the driving wheel 20. This adjustment method has a compact structure and saves space.

[0038] In order to achieve that the same driving component drives the cam 52 and the driving wheel 20 to rotate at the same time, in a specific embodiment, the container transportation system may also include a gear transmission assembly, and the motor drives the mounting base to rotate around the hinge shaft 40 while also driving each driving wheel 20 to rotate through the gear transmission assembly.

[0039] In the above embodiments, each driving wheel 20 can be installed on the same rotating shaft, and the rotating shaft is rotatably supported on the mounting seat through a bearing. The motor drives the rotating shaft to rotate to drive each driving wheel 20 to rotate.

[0040] This article provides a specific implementation in which the number of the driving wheels 20 is two, and the two driving wheels 20 are respectively located at two ends of the rotating shaft, and the middle part of the rotating shaft is rotatably supported on the mounting seat.

[0041] Of course, the number of driving wheels 20 on the same rotating shaft is not limited to two, and may also be three or more.

[0042] Practice has proved that the overall height of the container movement system of the above structure is less than or equal to 50 mm.

[0043] There are many ways to implement the specific structure of the detection component 30, as long as the above functions can be achieved. The detection component 30 can be integrated on the mounting base for easy installation and accurate detection.

[0044] In a specific embodiment, the mounting base may include a box body, the detection component 30 includes a body and a detection end, the motor and the body are both located inside the box body, the top wall of the box body is provided with an opening, and the detection end is provided corresponding to the opening.

[0045] In the above embodiment, the box body can protect the motor and the detection component 30, thereby increasing the service life of the two.

[0046] The detection component 30 is preferably an infrared inductive detection component 30. When the inductive detection component 30 senses that an upper container has passed, the driving wheel 20 extends out of the ground, contacts the bottom of the container, and drives the container to run. After the container has passed, the inductive detection component 30 senses that no container has passed, and the driving wheel 20 is retracted to the initial state.

[0047] In addition, the present invention also provides a rail vehicle, including a carriage, on which any of the above-mentioned container transportation systems is fixed.
