Narrow roadway omnidirectional AGV forklift

Abstract

The invention provides a narrow roadway omni-directional AGV forklift. The narrow roadway omni-directional AGV forklift comprises a U-shaped half-surrounding forklift body, a forward moving type portal and a forward moving guide mechanism. A supporting and sliding channel is provided for the forward-moving type portal through the U-shaped semi-surrounding vehicle body, the front-back distance of the vehicle body is compressed, the vehicle can adapt to the narrow roadway operation environment, the roadway space is compressed, and the warehouse goods allocation storage density is improved. The forward-moving guide mechanisms are arranged on the upper side and the lower side of the U-shaped half-surrounding vehicle body, the inverted-F-shaped arrangement is adopted, the overall rigidity of the guide mechanisms is greatly improved, the forward and backward moving speed of the portal frame is guaranteed, and the forward-moving guide mechanisms are more suitable for storing and taking scenes with heavy loads and high efficiency requirements. According to the forklift, the forklift body does not need to be controlled to move front and back in the goods taking and placing process, the goods can be taken and placed rapidly through sliding of the portal frame, and the storage and taking efficiency is higher.

Description

technical field [0001] The present application relates to the technical field of unmanned storage, in particular to an omnidirectional AGV forklift truck in a narrow lane. Background technique [0002] The modern warehousing industry is increasingly pursuing intensive storage. For a warehouse of the same area, the width of the lanes between the shelves determines the total amount of material storage in the entire warehouse. Therefore, AGV forklifts suitable for narrow lanes are more and more popular with customers. [0003] The body layout of the traditional omnidirectional AGV forklift is usually set to be narrow along the roadway direction (X direction), usually in the range of 1000mm to 1500mm, which leads to the narrowing of the spacing between the forklift walking wheels. When a forklift with a narrow body is driving in the roadway, in order to ensure the stability of the body, it is necessary to control the driving speed to be low. [0004] The stroke of the traditio...

Problems solved by technology

During this process, the forward movement of the forklift body requires the intervention of the navigation and positioning system. Usually, the forward movement speed is relatively slow, which cannot meet the purpose of fast pick-up and release.

[0005] The traditional omnidirectional AGV forklift forward-moving gantry is driven by oil cylinders, and oil cylinders need to be arranged inside the body in the Y direction. Therefore, it is usually necessary to design the body in the Y direction to be very long, resulting in the width of the aisle in the shelf needs to be widened accordingly, reducing the warehouse cargo. bit storage density

[0006] In the traditional omnidirectional AGV forklift, the forward-moving mast only has a single guiding mechanism at the lower end of the mast. When the forklift is picking up and placing goods on heavy-duty or high-level shelves, it is difficult to guarantee the stability of the mast's forward movement, and the forward speed is generally low. , affecting the overall access efficiency
