Sheep eye hook device of crane

Abstract

The invention relates to a sheep eye hook device of a crane, in particular to a hanger used on the crane for grabbing packed cargos, general cargos and other heavy objects, and the sheep eye hook device belongs to the technical field of the hoisting machinery. The hook device is characterized in that yoke plates on both sides are separated by a sleeve and form a hook body through bolts and nuts; a hook is arranged in a cross beam, hoisting nuts are used to compress a bearing installed on the upper part of the hook so as to fix the bearing on the cross beam; the cross beam is installed on the lower part of the hook body, the two ends of the cross beam are clamped by card boards and fixed by bolts. A pulley is installed on the sleeve outside a pulley shaft through a bearing; the sleeve is provided with a support ring; the both ends of the bearing are fixed by a bearing cover plate; the pulley shaft is installed in the middle of the hook body; one end of the pulley shaft is fixed by a shoulder, the other end is fixed by a card board and bolts; and the upper cover of the hook body is fixed by bolts and nuts. The sheep eye hook device has simple, compact and reasonable structure; and by using the hook device, the working intensity of the operating personnel can be lowered, the steel wire rope can be well prevented from sliding outside under an abnormal external force, and the whole hoisting operation can be safe and reliable.

Description

technical field [0001] The invention relates to a goat's eye hook device of a crane, in particular to a spreader used on a crane for grabbing heavy objects such as cargo and miscellaneous goods, and belongs to the technical field of hoisting machinery. Background technique [0002] At present, in docks, freight yards and other places, cranes are used to grab heavy objects such as piece goods and miscellaneous goods, usually through steel wire ropes or special spreaders to lift goods in series. If a wire rope or a special spreader is used for hoisting, it is very unsafe, and the operator's work intensity is high. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a simple and reasonable structure, which can reduce the work intensity of operators, and the whole hoisting operation is safe and reliable crane eye hook device. [0004] According to the technical solution provided by the present inven...
