Technical Field

[0001] The present application relates to the technical field of RGV trolleys, and more specifically, to an anti-collision structure for RGV trolleys. Background Art

[0002] RGV is a rail-guided vehicle, also known as a rail-guided shuttle vehicle. The RGV vehicle can be used in various warehouses with high-density storage methods. The vehicle channel can be designed to any length, which can increase the storage capacity of the entire warehouse. During operation, there is no need for a forklift to enter the aisle, making it safer.

[0003] After searching the publication (announcement) number: CN218200556U, an anti-collision structure for RGV trolleys is disclosed, which belongs to the technical field of RGV trolleys, and includes a trolley body, and the front and back of the trolley body are fixedly connected with two first springs. The application sets rollers, rollers, slots, clamping rods, clamping plates, first springs, second springs and anti-collision beams... At the same time, the trolley body has a good anti-collision effect, which greatly avoids the collision between the trolley body and the goods and causes damage. However, the clamping plate of the application is set in a "U" shape, and the distance between the two ends of the clamping plate cannot be adjusted, which is not convenient for clamping and fixing box-type goods of different specifications, reducing the scope of application of the device.

[0004] In order to solve the above problems, the present application provides an anti-collision structure for an RGV vehicle. Utility Model Content
