Description

Carrying and stacking vehicle capable of loading multiple cargoes Technical Field The invention relates to the technical field related to carrying machinery, in particular to a carrying fork truck capable of carrying multiple cargoes. Background Fork trucks are industrial transportation vehicles, and are various wheeled transportation vehicles that perform handling, stacking, and short-distance transportation operations on pallet goods. The transportation of large articles for storage is commonly done using fuel oil or battery powered. Fork trucks can be roughly classified into carrier trucks and stacker trucks according to the functional classification. The carrier is used for carrying cargoes, the carrier does not need to bear the function of carrying cargoes, the cargoes only need to be transferred from one place to another place, the lifting height of a fork is generally not higher than 300mm, and the stacker is used for carrying cargoes, the carrier is mainly used for carrying cargoes, and the carrier does not generally bear the function of carrying cargoes, and only a plurality of cargoes placed at one place need to be stacked. The carrier and the stacker perform their own functions and cooperate together to complete cargo carrying and stacking. However, when the existing carrier is used for forking goods, only the goods of a single tray can be forked at one time, and then only the goods of the single tray can be carried, so that the efficiency is extremely low, and the ever-increasing logistics requirements cannot be met. If the carrying efficiency is increased, the number of carrying trolleys is increased, the operation cost is greatly increased, the maintenance cost is increased, and the work difficulty of a dispatching system, the work intensity of dispatching workers and the work load are increased; In order to solve the problem, the conventional carrier with the patent number of CN216190838U provides the following technical scheme that the carrier comprises a shell, a first telescopic assembly and a second telescopic assembly, wherein a first guide rail and a second guide rail are arranged on the shell; the first telescopic assembly comprises a first driving piece, a sliding plate, a lifting mechanism and a first fork, the sliding plate is slidably arranged on the first guide rail, and the first driving piece is connected with the sliding plate to drive the sliding plate to move along the first guide rail; the second telescopic assembly comprises a second driving piece and a second fork connected with the second driving piece, the second fork is slidably arranged on a second guide rail, so that the second fork can move along the direction of the second guide rail under the driving of the second driving piece, the technical scheme adopts the guide rail to move to realize telescopic inserting legs and telescopic covering forks, and further realize double-tray carrying, but the effect realized by the technical scheme is only suitable for carrying, stacking cannot be completed, and due to the structural problem, only double-tray carrying can be realized during carrying, the aspect of improving carrying efficiency is extremely limited, meanwhile, the technical scheme is excessively low, when the stack of goods in the tray is excessively high, the truck also needs to move a distance to release another tray after the next tray is put down, thus leading to the reduction of the carrying efficiency of the truck, and simultaneously, the technical scheme adopted by the technical scheme is very low in the carrying range of U216190838, thus leading to the carrying of the truck being very low in the carrying range of the U-shaped carrier being very small, and the carrying of the U-shaped carrier being very small in the carrying range being suitable for the carrying of the U-shaped carrier being very small, the capability of improving the conveying efficiency is also severe, so that the device is not suitable for popularization and use. In order to solve the problems that the carrying efficiency of the carrying vehicle is low, the application range of the existing double-tray carrying vehicle is small, high-efficiency carrying cannot be carried on trays with higher tray cargoes, stacking function cannot be achieved, and the like, the invention provides a carrying stacker capable of loading multiple cargoes. Disclosure of Invention Aiming at the defects of the prior carrier in the use process, the invention provides the carrier stacking vehicle capable of loading multiple cargoes, has the advantage of multiple pallet carrying, and solves the technical problems in the prior art. The invention provides a carrying fork truck capable of loading multiple cargoes, which comprises a fork truck shell, wherein a universal driving wheel is embedded in the bottom surface of the fork truck shell, a lifting platform is arranged in the middle of the inner wall of the fork truck shell, the lifting platform is connected with th
