The flow dividing and combining mechanism is arranged on the running track and can change the motion track of the transport vehicle on the running track, so that the transport vehicle can arrive at the correct place to take and place the goods. A plurality of transport vehicles and flow splitting and combining mechanisms can be arranged on the running track, so that the running efficiency of the whole aerial transport system is higher.

In one embodiment of the present disclosure, as shown in fig. 1, 2, and 3, the air transportation system includes a travel rail 2, a transport vehicle 1, and a branching and converging mechanism 3. The running track 2 is annularly arranged, the running track 2 with the track of an annular contour further comprises a section of running track 2 with the track of a curve, the number of the flow dividing and combining mechanisms 3 is three, the number of the transport vehicles 1 is six, the three flow dividing and combining mechanisms 3 are respectively positioned at different positions of the running track 2, and the two flow dividing and combining mechanisms 3 are used for changing the moving track of the transport vehicles 1 in the running track 2 and enabling the transport vehicles 1 to enter or leave the running track 2 in the annular contour. Besides the arrangement of the air transportation system in the above embodiment, the track shape of the running track 2 may also be other shapes, and the number and the positions of the transportation vehicle 1 and the flow dividing and merging mechanism 3 may also be other numbers or positions, which is not described herein again.

The running track 2 is integrally I-shaped, and comprises an upper plate 22 extending along the horizontal direction and a lower plate 24 arranged parallel to the upper plate 22, a connecting plate 23 extending along the vertical direction and used for connecting the upper plate 22 and the lower plate 24 is arranged between the upper plate 22 and the lower plate 24, and a guide wall 21 is further arranged on the running track 2.

The transport vehicle 1 comprises a driving wheel 111 and at least one guide wheel, the driving wheel 111 is used as the main contact part of the transport vehicle 1 and the running track 2, the driving wheel 111 can apply positive pressure to the running track 2 under the action of gravity of the transport vehicle 1, and the running track 2 applies counter pressure to the driving wheel 111, so that the running track 2 can support the transport vehicle 1. It can be understood that the transport carriage 1 is suspended on the running rail 2 by the drive wheels 111.

At least one guide wheel is provided on the transport vehicle 1 and is configured for guiding engagement with the running track 2, and the at least one guide wheel may be engaged with the driving wheel 111 to hold the transport vehicle 1 on the running track 2 and guide the movement of the air transport vehicle along the extending direction of the running track 2.

The center of gravity of the transport vehicle 1 is offset from the center position of the drive pulley 111, and is configured such that, after being carried on the running rail 2 by the drive pulley 111, the transport vehicle 1 has a first torque M1 deflected relative to the running rail 2 by gravity, and at least one guide wheel is pressed against the running rail 2 by the first torque M1. The first torque M1 causes the transport carriage 1 to deflect clockwise or counterclockwise relative to the travel rail 2, so that the at least one guide wheel abuts against the travel rail 2.

For example, the running track 2 is divided into a first track side and a second track side, the driving wheel 111 is carried on the first track side of the running track 2, when the transport vehicle 1 is suspended on the running track 2, the first torque M1 enables the transport vehicle 1 to deflect in a counterclockwise or clockwise direction perpendicular to the extending direction of the running track 2, so that at least one guide wheel is tightly attached to the running track 2, and compared with the prior art in which a gap exists between the guide wheel and the track, the guide wheel in the present disclosure is tightly attached to the running track 2, so that the transport vehicle 1 does not shake during running, and running of the transport vehicle 1 is more stable. Stability in the transport vechicle traveles is as the first restrictive condition of restriction air transportation system transport speed, and this disclosure solves this problem after, the transport vechicle can be allowed to operate with higher speed, when improving transport vechicle stability, has further promoted the speed of transport vechicle, has improved transport efficiency.

In one embodiment of the present disclosure, as shown in fig. 2, one guide wheel is provided as the first guide wheel 121. The driving wheels 111 are carried on a first rail side of the running rails 2 so that the transport vehicle 1 can be suspended on the running rails 2. When the center of gravity of the transport vehicle 1 is shifted toward the second track side with respect to the center of the drive wheels 111, the transport vehicle 1 has the first torque M1 that is deflected counterclockwise with respect to the travel track 2 by its own weight. The running rail 2 is provided with a guide wall 21 for engaging with the first guide wheel 121, and the guide wall 21 is disposed in a path in which the first guide wheel 121 is deflected counterclockwise, whereby the first guide wheel 121 can be brought into close contact engagement with the guide wall 21 of the running rail 2 by the first torque M1.

On the basis of the above disclosure, when the center of gravity of the transportation vehicle 1 deviates to the first track side with respect to the center of the driving wheel 111, the transportation vehicle 1 has a tendency of deflecting clockwise with respect to the running track 2 under the action of its own gravity, and at this time, as long as the guide wall 21 is disposed in the path along which the first guide wheel 121 deflects clockwise, the first guide wheel 121 can be brought into close contact with and fit with the guide wall 21 of the running track 2 under the deflection tendency, and will not be described in detail herein.

When the transport vehicle 1 travels in a straight line on the travel track 2, the first torque M1 applied to the transport vehicle 1 does not substantially change, so the first guide wheel 121 still clings to the travel track 2 under the action of the first torque M1, and the first guide wheel 121 makes the transport vehicle 1 travel more smoothly, as with the above principle.

When the transport vehicle 1 makes a turn on the travel track 2, the transport vehicle has a centrifugal force deviating from the travel track 2, and the first guide wheel 121 is in close contact with the travel track 2 by the first torque M1 and the centrifugal force. During the travel of the transportation vehicle 1, since the travel track 2 turns in a different direction, for example, in a counterclockwise direction or in a clockwise direction, the direction of the centrifugal force when the transportation vehicle 1 turns may be directed in the first track-side direction or the second track-side direction.

For example, when the running track 2 has a ring-shaped structure and the transport vehicle 1 runs in one direction at all times, for example, in a counterclockwise direction, the direction of the centrifugal force to which the transport vehicle 1 is subjected during turning is fixed, for example, the direction of the centrifugal force always points in the first track side direction. Under the effect of this centrifugal force, the transport carriage 1 may have a moment that is offset in the direction of the first track side relative to the running track 2, and it is also possible for the transport carriage 1 to have a second torque M2 that is deflected clockwise relative to the running track 1, see fig. 2.

When the direction of the second torque M2 is opposite to the direction of the first torque M1, in order to ensure that the first guide wheel 121 can always keep close contact with the running rail 2 when the transportation vehicle 1 is turning, it is necessary to ensure that the second torque M2 is smaller than the first torque M1, that is, the second torque M2 generated by the centrifugal force of the transportation vehicle 1 is not enough to overcome the first torque M1 generated by the deviation of the gravity center of the transportation vehicle 1.

In an embodiment of the present disclosure, the direction of the second torque M2 generated by the transport vehicle 1 during turning can be the same as the direction of the first torque M1 by changing the traveling direction of the transport vehicle 1, in this embodiment, since the first torque M1 and the second torque M2 are the same, the first guide wheel 121 can still contact and fit with the guide wall 21 of the traveling rail 2 without being separated from the guide wall, and the stability of the air transport vehicle during turning and straight traveling can be ensured.

In the above embodiment, no matter the transport vehicle 1 deflects at the first track side or at the second track side, the guide wheels will cling to the running track 2, so that the transport vehicle 1 will not shake during running, and the running stability of the transport vehicle 1 is improved.

In another embodiment of the present disclosure, as shown in fig. 2, two guide wheels are provided, a first guide wheel 121 and a second guide wheel 122, respectively. When the transport vehicle 1 travels in a straight line in the travel track 2, the first guide wheel 121 is tightly attached to the travel track 2 under the action of the first torque M1, the second guide wheel 122 is far away from the travel track 2 under the action of the first torque M1, in the process, the first guide wheel 121 serves as a main supporting point of the transport vehicle 1 and the travel track 2 in the horizontal direction, and the first guide wheel 121 can roll along the extending direction of the travel track 2, so that the transport vehicle 1 cannot shake.

When the transport vehicle 1 turns in the running track 2, the transport vehicle receives centrifugal force to generate a second torque M2, when the second torque M2 is opposite to the first torque M1 and is larger than the first torque M1, the first guide wheel 121 is far away from the running track 2 under the action of the second torque M2, and the second guide wheel 122 is tightly attached to the running track 2 under the action of the second torque M2, in the process, because the second torque M2 is larger than the first torque M1, the transport vehicle 1 deflects in the opposite direction in the direction of extending perpendicular to the running track 2, and the second guide wheel 122 replaces the first guide wheel 121 to be tightly attached to the running track 2, so that the air transport vehicle cannot shake. In the whole process that transport vechicle 1 traveles, there is first leading wheel 121 or second leading wheel 122 all the time and hugs closely the track 2 that traveles, so transport vechicle 1 all the in-process that traveles all the time can not take place to rock, has guaranteed that transport vechicle 1 is traveling steadily in whole process that traveles.

In one embodiment of the present disclosure, referring to fig. 2, the first guide wheel 121 and the second guide wheel 122 are located on the same side of the running track 2, the first guide wheel 121 and the second guide wheel 122 are arranged at intervals in the horizontal direction, so that a gap exists between the first guide wheel 121 and the second guide wheel 122, the running track 2 has a guide wall 21 extending between the first guide wheel 121 and the second guide wheel 122, and the guide wall 21 is used as a direct contact part of the running track 2 and the first guide wheel 121 or the second guide wheel 122, so that the first guide wheel 121 and the second guide wheel 122 can be respectively attached to the guide wall 21 in different running processes, and the air transport vehicle does not shake in different running processes.

In another embodiment of the present disclosure, referring to fig. 2, the first guide wheel 121 and the second guide wheel 122 are located on the same side of the running rail 2, the first guide wheel 121 and the second guide wheel 122 are arranged at intervals in the height direction, the same side wall of the running rail 2 is respectively matched with the first guide wheel 121 and the second guide wheel 122, for example, under the action of the first torque M1, the transportation vehicle 1 deflects counterclockwise relative to the running rail 2, in this process, the first guide wheel 121 is tightly attached to the side wall of the running rail 2, and the second guide wheel 122 in the vertical direction is far away from the side wall of the running rail 2. Similarly, when the transportation vehicle 1 deflects clockwise relative to the running track 2, the second guide wheel 122 is tightly attached to the side wall of the running track 2, and the first guide wheel 121 is far away from the side wall of the running track 2, so that the transportation vehicle 1 cannot shake in different movement processes.

In one embodiment of the present disclosure, as shown in fig. 2, four guide wheels are provided, which are two first guide wheels 121 and two second guide wheels 122, respectively, the two first guide wheels 121 being engaged with different sides of the running rail 2, and the two second guide wheels 122 being engaged with different sides of the running rail 2. For example, one set of the first guide wheels 121 and the second guide wheels 122 may be respectively disposed on both sides of the lower plate 23, and the other set of guide wheels may be disposed at a different height from the former set of guide wheels, for example, disposed on both sides of the guide wall 21 of the travel rail 2.

When the transport vehicle 1 travels straight in the travel track 2, the transport vehicle 1 is deflected in a first track-side direction relative to the travel track 2 by the first torque M1, in which process the two first guide wheels 121 are pressed against the travel track 2 and the two second guide wheels 122 are moved away from the travel track 2.

When the transport vehicle 1 makes a turn in the travel track 2, the second torque M2 is greater than the first torque M1, the transport vehicle 1 deflects in a second direction relative to the travel track 2, the two second guide wheels 122 are pressed against the travel track 2, and the two first guide wheels 121 are spaced apart from the travel track 2. At least two first guide wheels 121 and at least two second guide wheels 122 are arranged, so that the at least two first guide wheels 121 or the at least two second guide wheels 122 bear force when clinging to the running track 2, the transport vehicle 1 deflects under the action of gravity, the deflection force generated by the first torque M1 is influenced by the gravity of the transport vehicle 1 and the gravity of the transport vehicle 1 for loading goods, under the condition of not changing the mass of the transport vehicle 1, the transport vehicle 1 can bear more goods by increasing the number of the first guide wheels 121 and the second guide wheels 122, and meanwhile, the running stability of the air transport vehicle can also be improved.
