Cantilever crane

Abstract

The invention provides a cantilever crane. The cantilever crane comprises a supporting base, a stand column, a first air cylinder, a telescopic rod, a limited block, a bearing, a positioning column, acantilever beam, a connecting plate, a fixed plate, a motor, an outer gear ring, connecting rods, connecting seats, second air cylinders, clamping jaw fixed plates and clamping jaws, wherein the stand column is arranged at the upper end of the supporting base; the first air cylinder is arranged inside the stand column; the telescopic rod is arranged at the upper end of the first air cylinder; thelimited block is arranged at the outer end of the telescopic rod; the outer gear ring is arranged above the limited block; the connecting plate is arranged at the right side of the positioning columnand is located at the lower end of the cantilever beam; the fixed plate is arranged at the end of the connecting plate; the motor is arranged at the upper end of the fixed plate; and clamping devicesare arranged at the two opposite sides of the cantilever beam. The cantilever crane has a novel structure, and achieves the effect that the clamping jaws clamp the two sides of goods simultaneously through the clamping devices; the motor is used for driving a gear to rotate, so that the cantilever beam rotates around the stand column; after the cantilever beam reaches a designated position, the goods is unloaded; and the cantilever beam at the other end continues to load the goods, and thus, the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of crane equipment, in particular to a cantilever crane. Background technique [0002] The working strength of the traditional cantilever crane is light. The crane is composed of a column, a slewing arm slewing drive device and an electric hoist. The lower end of the column is fixed on the concrete foundation through anchor bolts, and the cantilever is driven by a cycloidal pinwheel reduction device. Make straight runs on the cantilever beam I-beam and lift heavy objects. [0003] The cantilever beam crane is a new generation of light lifting equipment made to adapt to modern production, but the height of the column of the traditional cantilever crane is generally not adjustable, and the usability is not flexible enough to meet the work requirements of special occasions. In summary , it is necessary to develop a cantilever crane with innovative structure, convenient construction and transportation, and better perform...
