Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of shuttle technology, and more particularly to a circular rail shuttle. Background Technology

[0002] With the development of automated logistics systems and automated warehouses, RGVs have been widely used in the logistics field. RGVs can be easily connected to other logistics systems automatically, such as inbound / outbound platforms, various buffer stations, conveyors, elevators, and robots, to transport materials according to plan. In addition, RGVs require no human operation, operate at high speed, and can significantly reduce the workload of warehouse management personnel and improve labor productivity.

[0003] The existing technology, patent application number 2022230028133, entitled "A Circular Rail Shuttle," describes a system where "guide wheels are installed on all four wheel boxes to ensure the shuttle's wheels always run on a circular track. The driven wheel assembly is connected to the frame via a slide rail assembly, allowing it to move along the slide rail assembly. When the shuttle runs along the semi-circular track, the distance between the inner driven wheel assembly and the outer driving wheel assembly changes. At this time, the driven wheel assembly can maintain balance with the circular track through the slide rail assembly, improving stability during transport." However, in actual use, this shuttle significantly increases transmission efficiency and energy consumption during movement, resulting in substantial energy waste and high equipment costs, thus failing to meet the requirements of the existing technology. Summary of the Invention

[0004] In view of this, the purpose of one or more embodiments of this specification is to provide a circular rail shuttle to solve the problem of high cost of rail vehicles in the prior art.

[0005] Based on the above objectives, one or more embodiments of this specification provide a ring-shaped rail shuttle, including an inner rail, an outer rail, and a shuttle. The inner rail and the adjacent surface of the outer rail are respectively provided with a first track and a second track on the upper and lower sides. The cross-sections of the first track and the second track are both semi-circular, and the radius of the second track is larger than the radius of the first track.

[0006] An auxiliary external support bracket is fixedly installed on the periphery of the outer rail, and an external rack is fixedly installed on the inner side of the auxiliary external support bracket;

[0007] The shuttle is installed between the inner and outer rails, and a transmission device and a guide device are installed below the shuttle. The outer rack meshes with the transmission device.

[0010] The transmission gear meshes with the external rack.

[0011] Preferably, the guiding device includes: a first pulley fixedly installed on the outside of the central rod below the base frame, the first pulley being matched with the first track.

[0012] Preferably, a second pulley is fixedly installed on the outside of the center rod below the first pulley, and the second pulley matches the second track;

[0013] The first pulley is larger than the second pulley.

[0014] Preferably, the bottom end of the power rod is fixedly installed to an external power source.

[0015] Preferably, the shuttle includes: side panels, and the side panels are fixedly installed on the front and back of the shuttle respectively.

[0019] As can be seen from the above, the circular rail shuttle provided by one or more embodiments of this specification transmits power to the power gear, and then through the transmission of the toothed chain, transmits the power to the transmission gear, causing it to rotate and move with the external rack. During the movement, the first and second pulleys below rotate to realize the horizontal circular movement of the shuttle.
