Abstract

The invention provides a rubber-tired container gantry crane and a steering device thereof. The steering device is characterized in that the device comprises a cart equalizer bar, a left supporting cart frame, a right supporting cart frame, pivoting supports and a push rod which can move in two directions; left wheels are arranged below the left supporting cart frame; right wheels are arranged below the right supporting cart frame; the left supporting cart frame is provided with an area allowing a pin roll connection; the left supporting cart frame and the right supporting cart frame are connected to the cart equalizer bar through the pivoting supports; one end of the push rod is connected to a pin roll of the left supporting cart frame and the other end of the push rod is connected to a pin roll of the right supporting cart frame; and the two ends of the push rod move in the same direction to drive the left supporting cart frame and the right supporting cart frame to rotate in the same direction. The steering device realizes a direction change without a lifting-up structure, does not need a connecting rod and its associated parts, has the advantages of less parts, light quality and compact structure.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a tire-type container gantry crane and a steering device thereof. Background technique [0002] The rubber-tyred container gantry crane (RTG) is a loading and unloading machine used for loading, unloading and stacking of containers at the wharf. There are generally several runways in the terminal yard. In order to be able to change the site, the crane is equipped with a 90° right-angle steering device and a 360° in-situ steering device. In the early stage, the wharf yard was provided with a fixed place for steering, and steel plates for steering were laid at the fixed place. When the crane is going to turn, move the crane to a fixed location, make the tires contact the steel plate, and then turn. In this way, the steering resistance of the tire can be appropriately reduced, the wear of the tire can be reduced, and the service life of the tire can be prolonged. But such ope...
