Abstract

The invention relates to an anti-shaking device for a crane. The anti-shaking device comprises a supporting frame, a main beam, an operation trolley, lifting mechanisms, a sling and a lifting hook arranged at the lower part of the sling; the anti-shaking device is arranged at the lower part of the operation trolley, and comprises supporting rings, wherein a horizontal central shaft is arranged inthe supporting rings in a sleeved mode, and the central shaft can freely rotate around the axis of the central shaft; an anti-shaking cylinder is coaxially arranged outside the central shaft in a sleeving mode, and the anti-shaking cylinder is meshed with the central shaft through an acceleration gear set; the sling penetrates through the cylinder wall of the anti-shaking cylinder, and then is fixedly arranged on the shaft surface of the central shaft; and when the lifting hook is located right below the central shaft, the sling is in a vertical straight line shape. According to the anti-shaking device, the swing amplitude in the suspension process of weights can be effectively relieved, so that rapid stability recovery of cargoes is promoted, operators can safely and accurately land the weights conveniently, stacking stability and accuracy are guaranteed, and carrying efficiency is effectively improved.

Description

technical field

[0001] The invention relates to a crane accessory, in particular to a device for alleviating the shaking of heavy objects. Background technique

[0002] A crane is a large-scale handling equipment, mainly used for cargo handling in warehouses, docks, etc.; the main components of the crane include a support frame, a main beam, a running trolley and a hook placed under the running trolley; the goods are hung by hooks Traction, moving to the designated position through the handling of the running trolley; in the process of hoisting and handling, the heavy object will swing back and forth in the plumb plane due to the inertial force and horizontal wind load. When the heavy swing is too large, it may The suspension is not firm, and there is a big safety hazard; at the same time, the swinging heavy object is not easy to fall, and when the heavy object contacts the ground, it is easy to cause friction due to the swing, and damage the ground and the heavy object; als...
