Unbalanced load-resistant container spreader

Abstract

The invention discloses an unbalanced load-resistant container spreader, relates to the field of engineering machineries, and provides an unbalanced load-resistant container spreader with stable structure, good use effect and long service life and capable of effectively dealing with lifting of an unbalanced load container in the use process. The unbalanced load-resistant container spreader sequentially comprises a rotating mechanism, a centering mechanism, a pedestal and a grabbing mechanism from top to bottom; the rotating mechanism comprises a rotation driving device and a rotating table; the centering mechanism is connected between the rotating table and the pedestal, and comprises four centering assemblies, and each of the centering assemblies comprises an upper ball socket base, a hydraulic rod, a hydraulic cylinder and a lower ball socket base; the bottom surface of the pedestal is provided with a pair of mutually vertical chutes, and the chutes are mutually intersected, and respectively penetrate through the pedestal; and the grabbing mechanism comprises four grabbing claws for grabbing a container, and four linear driving devices for driving the grabbing claws. The unbalanced load-resistant container spreader has the characteristics of low hidden safety trouble, long service life, and effective dealing with lifting of the unbalanced load container in the use process.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to the improvement proposed to the container spreader. Background technique [0002] With the rapid development of my country's economic construction, the application of containers has become more and more extensive, making the demand for container spreaders also increasing. There are many container cranes in the prior art, most of which usually integrate the functions of hoisting and rotatability. However, people have found in actual use that due to the different weights and different placement positions of the objects in the container, the position of the center of gravity of the container after loading is often inconsistent with the position of the center of the container, that is, an eccentric load occurs; It has no effect on the normal use of the container, but it brings a huge load to the container spreader, which greatly reduces the service life of the container spreader...
