The supporting wheel 103 is arranged at the bottom of the front end of the supporting body, the supporting wheel 103 is a directional wheel which mainly plays a supporting role, and the supporting wheel 103 also plays a certain walking function in the front-back moving process of the forking mechanism 1. The lifting driving mechanism 102 is driven by a hydraulic cylinder and is mainly used for driving the fork 101 to vertically lift, so as to take goods, unload the goods and pile the goods. The specific structure of the lifting driving mechanism 102 is the prior art and will not be described here.

Specifically, in the embodiment, the rail guide wheels 104 are arranged on two sides of the rear portion of the supporting seat 100, and in the forward and backward movement process of the forking mechanism 1, the rail guide wheels 104 serve as the rear end support, and the first supporting wheel 103 serves as the front end support, so that the forward and backward movement stability of the forking mechanism 1 is ensured.

Specifically, in the present embodiment, a link 105 is disposed at the rear portion of the support base 100, and the support base 100 is rotatably connected to the link 105; two rail guide wheels 104 are respectively installed at both ends of the connecting rod 105.

In this embodiment, the fork taking mechanism 1 cooperates with the carrier body 2 of the unmanned pallet carrier to complete the fork taking and transferring of goods. Install C type guide rail 202 on the carrier main part 2, the track guide pulley 104 that this fork got mechanism 1 and set up moves along C type guide rail back-and-forth under power drive to make the fork get mechanism 1 and can push out forward and retreat backward the motion, and in the motion process, two supporting wheels 103 of front end support as the front end, and two track guide pulleys 104 at rear portion support as the rear end, have guaranteed that the fork gets mechanism 1 steady movement.
