Unmanned carrying vehicle for high-density storage warehouse transportation

Abstract

The invention relates to the technical field of storage equipment, and discloses an unmanned carrying vehicle for high-density storage warehouse transportation. The unmanned carrying vehicle comprisesa bearing base, bearing rods are fixedly connected to the upper end of the bearing base, lifting structures are movably connected to the bearing rods, and the lower end of the bearing base is movablyconnected with a mobile base through a rotating ring column. According to the unmanned carrying vehicle for high-density storage warehouse transportation, the projection of the lifting structures islocated inside the bearing base, so that regardless of the load, the projection of the gravity center is always located in the bearing base, the requirement of balance weight is small, the small and thin base can be stable, and the size of the carrying vehicle is reduced. Furthermore, the small vehicle can be driven into the bottom of a shelf. Meanwhile, the arrangement of a fork arm push-out structure is omitted, the position and posture of the carrying vehicle are judged and controlled by judging whether the electric potential of a vehicle body positioning device and a storage cell positioning device changes or not, and accurate control over operation of the carrying vehicle is completed at low equipment cost.

Description

technical field [0001] The invention relates to the technical field of storage equipment, in particular to an unmanned transport vehicle for high-density storage warehouse transportation. Background technique [0002] Unmanned vans are one of the important components of smart factories and smart workshops. They have been widely used in electronics, automobiles, chemicals, medicine, logistics, metallurgy, tobacco, assembly and other industries, replacing manual loading, handling, Unloading and other tasks have realized the automation of workshop logistics. [0003] High-density storage warehouses store more goods in a smaller volume through multi-layer storage. The corresponding handling trolley also needs to have a lifting function, usually with a structure similar to a forklift. , the car body is used to move automatically on the ground, but since the fork arm is located at the front of the car body, the car body needs a larger counterweight to achieve stability, and the e...

[0003] High-density storage warehouses store more goods in a smaller volume through multi-layer storage. The corresponding handling trolley also needs to have a lifting function, usually with a structure similar to a forklift. , the car body is used to move automatically on the ground, but since the fork arm is located at the front of the car body, the car body needs a larger counterweight to achieve stability, and the entire unmanned van is larger in size, which requires a large space in the warehouse The operating space of the unmanned van, which greatly increases the storage cost

[0004] In order to accurately control the entry and exit of goods, it is necessary to precisely control the operation of the truck. The existing control methods are usually based on inertial navigation technology, curve fitting methods, etc. to measure and adjust the pose of the vehicle body. However, based on inertial navigation The control method of the technology requires the use of an inertial navigation system, resulting in a higher cost of the unmanned van
