Description

Technical Field

[0001] The present invention relates to the field of intelligent logistics technology, and in particular to a synchronous belt self-resetting type unmanned aerial vehicle (RGV) outdoor transfer platform. Background Art

[0002] With the rapid development of industrial automation, intelligent transportation and intelligent warehousing have also been widely popularized. RGV and AGV can be seen everywhere in modern factories. RGV is a directional rail-mounted transport vehicle, and AGV is a transport platform with a control system without a fixed path. Usually, RGV is used more indoors in factories and is used to transport materials without any auxiliary mechanisms. RGV is generally composed of a control system, path planning, drive system, etc., covering automation control, sensor technology and robotics technology.

[0003] Drones are used in outdoor power systems, forests, ships and other areas that are highly dependent on meteorological data. They can be used for power line inspections and meteorological disaster inspections. When the set inspection time is reached, the car automatically moves outward, and starts the drone flight after reaching the designated location. The collected data is transmitted back to the background in real time through the 5G terminal. The background displays the picture on the platform through 3D simulation, and the current state is dynamically analyzed through edge computing, so as to achieve the purpose of inspection and prevention. When the drone returns, the drone will land on the AGV car at a fixed point. However, due to the landing accuracy problem, the landing point may deviate, which will make it inconvenient for the drone to automatically charge, and it is not conducive to quickly and efficiently transmitting the inspection data to the ground control station or data center through stable methods such as wired connection, and inaccurate landing will cause a waste of time. Summary of the invention

[0004] The present invention aims to solve the above-mentioned defects and provide a synchronous belt self-resetting UAV RGV outdoor transfer platform.

[0011] A further improvement includes providing a bottom plate at the lower portion of the support unit.

[0012] A further improvement includes that the support unit includes two channel steel members and a connecting rod, and the connecting rod connects the channel steel members in series.

[0013] A further improvement includes that the connecting rod is preferably a screw rod, and both ends of the screw rod pass through the channel steel member respectively and are connected and fixed by nuts.

[0015] The beneficial effects of the present invention are: the design drives the front and rear levers and the left and right levers to move the UAV by driving the reset mechanism, and automatically resets the UAV to return it to its initial state, reducing time waste due to inaccurate landing and improving work efficiency. After returning to its original position, the trolley drives the UAV back to the hangar for automatic charging. The design controls the movement of the trolley and the synchronous belt self-reset system through three sets of motors to achieve precise control requirements.

The two ends of the front and rear levers 8 are connected to one group of the driving reset mechanisms 7 through the corresponding active windows 10 opened on the carrying platform 2, so that the front and rear levers 8 can move relatively along the direction of the active windows 10. The two ends of the left and right levers 9 are connected to the other group of the driving reset mechanisms 7 through the corresponding active windows 10 opened on the carrying platform 2, so that the left and right levers 9 can move relatively along the direction of the active windows 10. The left and right levers 9 intersect with the front and rear levers 8 and do not interfere with each other. This design can push the drone back to its original position through the left and right levers 9 and the front and rear levers 8.

[0020] In this embodiment, if Figure 3 As shown, the driving mechanism 4 includes a driving motor 402, a driving gear 403 and a driven gear 404 arranged on the carrying platform 2, the output end of the driving motor 402 is connected to the driving gear 403, and the driving gear 403 transmits the power output by the driving motor 402 to the wheelset 5 through the chain 401 and the driven gear 404, so as to drive the wheelset 5 to rotate synchronously, thereby realizing the automatic movement of the RGV transfer platform. In a further implementation mode, the driven gear 404 is only arranged on one of the wheelsets 5, and the driving gear 403 is connected to the driven gear 404 through the chain 401, thereby providing power to the wheelset 5.

[0021] In this embodiment, a support member 6 is rotatably provided on the rotating shaft of the wheel set 5 , and the support member 6 is connected to the bearing platform 2 , thereby supporting the bearing platform 2 .

[0022] In this embodiment, in order to ensure that the RGV runs along the predetermined track and to ensure the accuracy and consistency of its running path, Figure 2 As shown, the transfer platform also includes a guide device 1 for guiding the wheelset 5. Specifically, the guide device 1 includes a plurality of support units. Guide rails 105 are radially laid on the upper part of the support units to connect the support units in series. The wheelset 5 rolls on the guide rails 105, thereby guiding and supporting the wheelset 5.

[0023] In a further embodiment, the guide rail 105 is disposed on the upper portion of the support unit via a fixing member 102 , and the fixing member 102 is located on both sides of the guide rail 105 . This design not only fixes the support unit but also serves to limit the axial movement of the guide rail 105 .
