A nested three-dimensional walking rail guided car with inner and outer cars

Abstract

The invention provides an inner-outer-vehicle-embedded three-dimensional walking rail guided vehicle. The vehicle is composed of an outer vehicle body, an inner vehicle body and a lifting drag device. The lifting drag device is arranged on the outer vehicle body. The inner vehicle body is connected with the lifting drag device through a lifting belt. In work, the outer vehicle body operates on a top layer of a cargo rack and can conduct linear reciprocating movement in the four directions on a rail on the top layer of the cargo rack; when the vehicle walks to the position above an assigned channel grid, the inner vehicle body can be put down through the lifting belt, and after the inner vehicle body is lifted to the assigned cargo layer along the channel grid, cargos can be stored and taken in the four directions according to instructions. By means of the inner-outer-vehicle-embedded three-dimensional walking rail guided vehicle, the defects in the prior art are overcome, the purpose that the cargos can be stored and taken in a non-sequential mode at any goods allocation of the three-dimensional cargo rack is achieved, the maximum of the storage density is guaranteed, while the storage efficiency is improved to the maximum degree, and the vehicle is especially suitable for random storage and taking of the high-density single cargo and has wide application and popularization prospects.

Description

technical field [0001] The invention relates to a trolley for automatic handling of logistics storage materials, which belongs to the technical field of mechanical and electronic equipment and logistics equipment manufacturing. Background technique [0002] Modern storage consists of three-dimensional shelves, intelligent handling equipment and computer management and control systems. Among them, intelligent handling equipment is the actual carrier of material handling, and its intelligence and automation directly restrict the efficiency of modern warehouse logistics. At present, the most common shelf structure and cargo transportation and storage mode used in three-dimensional warehouses can be roughly divided into single and double extension stackers and their shelf models, jacking track rail guide trolleys and their shelf models, and telescopic arm track Rail-guided trolley and its rack mode. [0003] In the three-dimensional warehouse that uses the stacker for inbound ...

AI Technical Summary

Problems solved by technology

The above storage mode improves the problem of insufficient space utilization caused by the single-double extension stacker and its shelf mode, but its first-in-last-out cargo delivery method makes it impossible for the rail-guided trolley to realize the random storage of a single piece of multi-variety goods. storage, which greatly affects the performance of the three-dimensional warehouse and the efficiency of inbound and outbound

[0005] The telescopic arm-type rail-guided trolley relies on two parallel guide rails laid on the ground for reciprocating movement, and can dock stably and accurately at each cargo position. The rail-guided trolley is equipped with a telescopic device perpendicular to the walking direction, which can be The goods are loaded and unloaded on both sides of the car body. This transportation mode improves the shortage of the jack-up track-guided trolley for accessing goods, but the space utilization rate of the shelf does not change compared with the stacker mode, and the rail-guided trolley The operation of entering and leaving the warehouse needs the assistance of external lifting equipment, which greatly affects the efficiency of entering and leaving the warehouse
