Abstract

The invention discloses a gantry structure of a portal crane. The gantry structure of the portal crane comprises a portal and a cylinder, wherein the cylinder is mounted on the portal; the portal is formed by welding a portal cross beam and a portal end beam; a plurality of cylinder reinforcing rib plates are welded in the cylinder at intervals in the height direction; a plurality of cylinder climbing ladders are arranged outside the cylinder; a cylinder protecting fence is arranged above a position, corresponding to each cylinder climbing ladder, on the cylinder; a ladder platform is arranged at the upper part of the cylinder; a platform protecting fence is arranged on the ladder platform; a portal ladder connected to the lowermost cylinder climbing ladder is arranged on the portal. The gantry structure of the portal crane has the advantages of stable structure, high reliability, large carrying force and convenience in daily maintenance and repair.

Description

technical field [0001] The invention relates to a portal type crane, in particular to a portal frame structure of the portal type crane. Background technique [0002] Portal cranes are developed with the development of the port industry. In 1890, for the first time, a fixed rotatable jib crane with a constant amplitude was installed on the running half-portal seat across the narrow wharf, which became an early port half-portal crane. Large, portal and semi-portal cranes are developed side by side, and the pitching jib and horizontal luffing system are generally used. After the Second World War, port portal cranes developed rapidly to facilitate multiple cranes to work side by side on the same ship. Rotary column portal cranes in which the rotating part is connected to the column are generally used, or the rotating part passes through large bearings. The rolling bearing type supporting slewing device connected with the door seat reduces the tail diameter of the rotating par...
