When being unloaded on device 13, whole work process is opposite with the process of above-mentioned entrucking.
Electric pallet truck among the above embodiment of the present invention, can realize makes article to be transported carry out transmission fortune thereon
Defeated purpose, it is easy to load and unload goods, and the sensor assembly for passing through setting so that whole transmitting procedure automation, improve whole
The intelligence degree of the individual electric pallet truck, and improve efficiency of transmission.Moreover, because the pallet 41 is along the cunning
Groove 31 is reciprocated between the bottom plate 10 and the top plate 20 so that the lifting process of the pallet 41 is steady, and article is not
Easily slide, while the electric pallet truck drives the lifting of the pallet 41 by ball screw arrangement so that the support
The rising height of disk 41 is greatly improved.
Fig. 6 to Fig. 7 is refer to, the electric pallet truck showing in second embodiment of the invention, the electricity among the present embodiment
Dynamic tray carriage and the electric pallet truck among first embodiment are more or less the same, and difference is, the electronic support in the present embodiment
Jiggering is on the basis of first embodiment:
The bottom of the bottom plate 10 is additionally provided with support meanss 15, and the support meanss 15 are located in the bottom of the bottom plate 10
On heart position, the support meanss 15 include cylinder 151 and sucker 152, the piston shaft of the sucker 152 and the cylinder 151
Free terminal be fixedly connected, the cylinder 151 be used for drive the sucker 152 towards or away from ground move.When need by
When the electric pallet truck is fixed, by controlling the cylinder 151, the sucker 152 is driven and ground absorption, increase are steady
Solidity.
The both sides of direction of transfer of the top of the supporting plate 421 along the vertical second conveyer 13 are installed with one respectively
Guard rail 424, the guard rail 424 are used to further ensure that article will not slide from the pallet 41.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
