Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of warehouse logistics, especially a synchronous lifting mechanism and four-way vehicle. BACKGROUND

[0002] The four-way shuttle vehicle is a logistics transport trolley applied in a warehouse logistics system, and mainly comprises a vehicle frame, a jacking mechanism, a driving wheel mechanism, a power supply, electrical control components and the like, wherein the jacking mechanism is an important component for jacking and reversing the goods;

[0003] In the prior art, the jacking mechanism is one of the important components of the four-way shuttle vehicle, and mainly serves to jack and reverse the goods. However, the existing jacking mechanism needs to bear the goods for a long time, and the goods to be borne are all stacked on the logistics pallet. The weight of the logistics pallet plus the goods themselves will exert pressure on the jacking mechanism. Moreover, the goods on the logistics pallet are not a whole, but are stacked by multiple goods. Therefore, the situation of one side being heavy and the other side being light will occur. Moreover, the jacking mechanism is generally symmetrically arranged. Therefore, under the pressure of the goods, the situation of the two sides of the jacking mechanism being out of synchronization in lifting will easily occur. Once the jacking mechanism is out of synchronization in lifting, the goods will easily roll over. SUMMARY
