Abstract

The invention discloses a portal type crane cantilever stand column supporting auxiliary fixing structure which comprises a crane body and a servo motor. A main arm is installed on the right side of the crane body in a hinged manner. A driving mechanism is installed in the crane body, the driving mechanism internally comprises an adjusting base, and in addition, the adjusting base is hinged to theinterior of the crane body. A supporting frame is fixedly installed on the top of the adjusting base, rotating shafts are symmetrically inserted in the upper side and the lower side of the interior of the supporting frame, and drive gears are symmetrically fixed to the outer walls of the front side and the rear side of each set of rotating shaft. By means of the portal type crane cantilever standcolumn supporting auxiliary fixing structure, an auxiliary supporting mechanism is connected between a cantilever body and the main arm, a triangular stable support formed among a supporting screw rod, the main arm and the cantilever body in the auxiliary supporting mechanism is used for conducting auxiliary supporting between the main arm and the cantilever body, and the cantilever body and themain arm can be firmer and more stable during running of the device.

Description

technical field [0001] The invention relates to the technical field related to cranes, in particular to a cantilever column support auxiliary fixing mechanism of a portal type crane. Background technique [0002] Portal crane is a jib type crane whose bridge frame is supported on the ground track or foundation through the outriggers on both sides. It can run along the ground track, making it easy to move. Railway vehicles or other ground vehicles can pass directly below to facilitate the loading and transportation of goods, so they are widely used in various docks or open stockyards; [0003] Due to the large single grabbing capacity of the portal crane, which can reach dozens or even hundreds of tons, in order to ensure the structural stability of the crane, the position of the cantilever is mostly fixed by the upper auxiliary beam, and there is no gap between the main arm and the cantilever. Auxiliary support fixation, resulting in insufficient support strength of the low...
