Description

Technical Field

[0001] The utility model relates to the technical field of transportation logistics equipment, in particular to a high-speed RGV logistics equipment. Background Art

[0002] With the development of science and technology in my country and the rise of the Internet, modern logistics concepts have been deeply rooted in the hearts of the people. The majority of users have a common understanding of the role of logistics and warehousing systems in promoting the development of various industries. What follows is the automated logistics system and automated warehouse. With the development of automated logistics systems and automated warehouses in China and even the world, many shortcomings of general automated systems and warehouses have been exposed. In order to make up for these shortcomings, RGV (rail-mounted shuttle vehicle) has been produced. It can be easily connected to other logistics systems automatically, such as in / out platforms, various buffer stations, conveyors, elevators and robots, etc., to transport materials according to plan. In addition, it does not require human operation and runs fast. Therefore, the workload of warehouse managers is significantly reduced and labor productivity is improved. At the same time, the application of shuttle vehicles can make the logistics system very simple. The land cost that occurs with this becomes high. Enterprises need to reasonably optimize logistics equipment in limited warehouses, and the speed of traditional RGV needs to be further improved. Utility Model Content

[0013] Beneficial effects of the utility model: The traditional RGV trolley uses a single travel reduction motor to drive the travel wheel to travel on the track and can only reach 160m / min. The travel wheel only travels on the track, which greatly increases the wear of the travel wheel. It is also easy for the vehicle body to shake due to coordination, and it is easy to slip during long-term work. In the present application, the two travel reduction motors that drive the RGV body to travel can reach a speed of 300m / min compared to the traditional one travel reduction motor.
