Portal moving device of front-moving AGV fork truck

Abstract

The utility model belongs to the technical field of fork truck, specifically discloses a front -moving formula AGV fork truck's portal frame mobile device, including the guide mechanism that is symmetrically installed on the inside wall of two front support legs, and the sliding mechanism that is fixedly connected in the portal frame rear end, the guide mechanism includes transmission rack, the sliding mechanism includes the moving frame, and the both sides symmetrical installation of moving frame have the transmission gear that is engaged connection with transmission rack, the gear shaft connection of transmission gear has drive mechanism, and drive mechanism drive transmission gear takes along transmission rack and moves the portal frame. The application moves the portal frame through transmission gear and transmission rack intermeshing traction, and rolls through the cooperation of the guide groove and the idler wheel, and is the main carrier of the load force and the moment that the portal frame and the goods produce. So the application can not only avoid transmission gear and transmission rack bearing too big and influence the service life, but also can keep transmission gear and transmission rack rigid transmission characteristics, and accurately control the portal frame moving distance.
