Description

Technical Field

[0001] This utility model relates to the field of RGV vehicle technology, specifically to an RGV driving wheel and track structure. Background Technology

[0002] With the development of automated logistics systems and automated warehouses in China and around the world, many shortcomings of conventional automated warehouses have become apparent. To address these shortcomings, RGVs (Rail-Guide Vehicles) have emerged. They can easily connect automatically with other logistics systems, such as inbound / outbound platforms, various buffer zones, conveyors, elevators, and robots, to transport materials according to a plan. Furthermore, they require no human intervention and operate at high speeds. This significantly reduces the workload of warehouse management personnel, improves labor productivity, and simplifies the logistics system considerably.

[0003] Traditional RGV (Remotely Ride-on Vehicle) rail flatcars, upon receiving a transport task, use a control system to drive a motor-driven roller to rotate, propelling the vehicle along the track. During travel, the friction between the roller and the track maintains a stable speed. Upon reaching the destination, the control system activates the braking device to bring the vehicle to a stop. Furthermore, through guiding devices and a laser guidance system, the vehicle can maintain the correct direction of travel in complex track environments.

[0004] However, the RGV wheels and tracks currently on the market are usually made of metal. During the operation of the RGV, the friction and vibration between the metals are severe, requiring frequent inspection and maintenance of the wheels and tracks. At the same time, it generates serious noise pollution, making it unsuitable for many situations. Therefore, it is necessary to develop a new RGV wheel and track structure. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An RGV driving wheel and track structure includes an RGV body and a track for the RGV body to drive.

[0008] The RGV body includes a vehicle body structure and a driving component. The driving component consists of driving wheels and guide wheels. The driving wheels and guide wheels are arranged side by side below the vehicle body structure and drive on tracks respectively. The outer walls of the driving wheels and guide wheels are rubber-coated wheels.

[0009] The track is assembled from multiple track sections.

[0010] As a preferred embodiment of the RGV driving wheel and track structure described in this utility model, each section of the track is designed with a groove and a protrusion at both ends, and multiple sections of track are sequentially spliced ​​together by the groove and protrusion structure.

[0011] In a preferred embodiment of the RGV driving wheel and track structure described in this utility model, the track piece is fixed to the ground by anchor bolts.

[0012] In a preferred embodiment of the RGV driving wheel and track structure described in this utility model, the track sheet is filled with a cushioning material, which is resin.

[0013] The beneficial effects of this utility model are: by coating the surface of the RGV running wheels with rubber, direct contact between the cast steel inside the running wheels and the track is avoided. At the same time, the track is filled with resin cushioning material, which reduces noise pollution during the RGV's operation, extends the service life of the track, and reduces vibration of the RGV running wheels during operation.
