An anti-sway slewing crane

Abstract

The invention relates to the technical field of rotary cranes, and concretely relates to an anti-shaking rotary crane, which cannot shake during a hoisting process so as to ensure the normal hoisting of goods. A telescopic crane jib and a supporting arm for supporting the telescopic crane jib are arranged on a rotary base; the telescopic crane jib comprises a fixed arm and multiple stages of movable arms; a lifting hook is arranged on the end part of the last stage of movable arm through a pulley device and a lifting rope; supporting rods are hinged to the bottom part of the last stage of movable arm, and comprise a fixed supporting rod hinged to the bottom part of the last stage of movable arm and a movable supporting rod sleeved in the fixed supporting rod; an iron block is arranged on the bottom part of the movable supporting rod and faces one side of the lifting hook; corresponding longitudinal guide rail grooves are formed in the fixed supporting rod and the movable supporting rod so as to form a telescopic guide rail; a lifting air cylinder is arranged on the other side of the fixed supporting rod; a piston rod of the lifting air cylinder is connected with the movable supporting rod; a sliding block is arranged in the guide rail and is connected with one end of a middle telescopic rod; and the other end of the middle telescopic rod is connected with the top part of the lifting hook.

Description

technical field [0001] The invention relates to the technical field of slewing cranes, in particular to an anti-shaking slewing crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. It is a common equipment in ships, construction sites, etc. Among them, hydraulic slewing cranes are common, and in order to meet various needs, there will be It is equipped with a telescopic boom, and the hook is set at the end of the movable arm of the last stage. When the object lifted by the hook is heavy and the hoisting position is not in a balanced position, shaking often occurs, especially some objects with liquid and other items will cause liquid splashing, which will have a great impact on hoisting. Contents of the invention [0003] In order to solve the above problems, the present invention provides an anti-shake slewing crane, which will not shake during the hoisti...
