Abstract

The application relates to a carrying robot including a fork. The fork includes a telescopic arm and a temporary storage tray. The telescopic arm includes a fixed arm and a movable arm connected to the fixed arm. The movable arm is telescopically movable relative to the fixed arm. The temporary storage tray is mounted to the fixed arm and is configured to temporarily store goods. The temporary storage tray is able to extend relative to the fixed arm. An extending direction of the temporary storage tray is consistent with an extending direction of the movable arm. When the fork pulls in or pushes out the goods, containers can be stably transferred between a stationary rack and the temporary storage tray.

First claim

What is claimed is:

1 . A fork configured to transfer a container, comprising:
a telescopic arm comprising a first arm, a second arm and a driving assembly, wherein the second arm is movably connected to the first arm, the second arm being telescopically movable relative to the first arm; and a temporary storage tray mounted to the first arm and configured to temporarily store the container, wherein the temporary storage tray is further configured to extend or retract relative to the first arm; wherein the second arm is provided with a connecting plate, the driving assembly being configured to drive the second arm to move relative to the first arm by using the connecting plate; wherein the temporary storage tray is provided with a rib; wherein the connecting plate is configured to abut against the rib so as to cause the temporary storage tray to retract relative to the first arm.

2 . The fork according to claim 1 , wherein the driving assembly comprises a chain wheel mechanism and a driving member;
wherein the connecting plate is fixedly connected to a link chain of the chain wheel mechanism, the chain wheel mechanism being configured to drive the second arm to move relative to the first arm by using the connecting plate.

3 . The fork according to claim 1 , wherein the driving assembly comprises a pulley mechanism and a driving member;
wherein the connecting plate is fixedly connected to the pulley mechanism, the pulley mechanism being configured to drive the second arm to move relative to the first arm by using the connecting plate.

4 . The fork according to claim 1 , wherein the first arm comprises:
an underframe; and a side wall connected to the underframe; wherein the second arm is mounted to the side wall, and the temporary storage tray is mounted to the underframe.
