Four-way walking trolley

Abstract

The invention discloses a four-way walking trolley comprising a supporting framework, a walking driving module and a reversing and jacking module, wherein the walking driving module and the reversingand jacking module are arranged on the supporting framework, and the walking driving module comprises a transverse walking wheel assembly, a longitudinal walking wheel assembly, a driving motor and across speed reducer connected with the driving motor; the reversing and jacking module comprises a reversing motor, a reversing speed reducer, a reversing shaft, a double-connecting-rod linkage mechanism, a jacking mechanism and a jacking framework; and a second synchronous belt is always in a tensioning state under the action of a first tensioning wheel, a second tensioning wheel or a third tensioning wheel in the process of reciprocating up and down along with a second synchronous driven wheel. According to the four-way walking trolley, the weight and the size of a robot are reduced, and therunning capacity and the object access efficiency are improved; and the four-way running function is achieved, cost is reduced, space is saved, meanwhile, the problem of leakage of a hydraulic deviceis solved, and the flexibility of a shuttle bus is improved.

Description

technical field [0001] The invention relates to a storage and transportation shuttle, in particular to a four-way traveling trolley. Background technique [0002] With the rapid development of the warehousing and logistics industry, higher and higher requirements are put forward for the utilization rate of the three-dimensional warehouse space. The space occupied by the incoming and unloading channels. [0003] The existing three-dimensional warehouse structure mostly adopts the model of one incoming and unloading roadway and multiple storage rack roadways vertically connected with it, which requires that the shuttle car must be able to travel in two directions perpendicular to each other, vertically and horizontally. In the prior art, the three-dimensional warehouse usually uses a sub-car system, that is, the mother car carries the sub-cars in the purchase and unloading lanes, and then the sub-cars drive out from the direction perpendicular to the direction of the mother c...

AI Technical Summary

Problems solved by technology

[0004] At present, there are very few shuttle vehicles used for intensive storage management and shelf handling in the market. Some existing products have various problems, such as the shuttle vehicle is too heavy, too large, not flexible enough, and has poor operating capacity. Low shelf access efficiency, insufficient load capacity, insufficient stability, leakage of hydraulic devices, etc.
