Abstract

The invention relates to the field of rotary cranes, and specifically relates to a folding-arm telescopic rotary crane. The folding-arm telescopic rotary crane comprises a base, wherein a rotary seatis installed on the base; a boom is hinged to the top of the rotary seat; a pulley is hinged to the top end of the boom; a lifting hook is installed on the pulley through a lifting rope; a motor driving the lifting hook to lift is installed on the rotary seat; the rotary seat comprises a rotary table at the bottom; the boom comprises a first-stage boom; an oil cylinder A is hinged to the rotary table; a piston rod of the oil cylinder A is hinged to the bottom surface of the first-stage boom; a second-stage boom is hinged to the top end of the first-stage boom; an oil cylinder B is further hinged to the bottom surface of the first-stage boom; a piston rod of the oil cylinder B is hinged to the bottom surface of the second-stage boom; a third-stage boom sleeves into the second-stage boom; anoil cylinder C is fixedly installed on the side surface of the second-stage boom; the top end of a piston rod of the oil cylinder C is fixedly connected with the third-stage boom; a guide wheel is further hinged to the top end of the first-stage boom; and the lifting rope is connected with the motor through the pulley and the guide wheel. The folding-arm telescopic rotary crane is larger in lifting range, and applicable to improvement for an existing rotary crane.

Description

technical field [0001] The invention relates to the field of slewing cranes, in particular to a folding-arm telescopic slewing crane. Background technique [0002] Slewing cranes are widely used on ships for vertical lifting and horizontal handling of heavy objects. At present, the booms of slewing cranes have fixed lengths. This kind of slewing cranes can intelligently lift objects within a fixed range. The arm length of the crane is realized; there are also telescopic booms, and the lifting range of this type of boom telescopic slewing crane is also limited. While increasing the lifting range, it also increases the limited occupation of the ship's deck. Valuable space, making room for movement on board smaller. Contents of the invention [0003] The object of the present invention is to solve the problem of insufficient hoisting range of the existing slewing cranes, and provide a folding-arm type telescopic slewing crane to greatly increase the hoisting range. [0004]...
