Super tonnage split lifting hook

Abstract

The invention discloses a super tonnage split lifting hook. The lifting hook comprises a movable pulley set, a lifting hook rod, a lifting hook shaft, a lifting hook body, a self-aligning roller bearing and a thrust self-aligning roller bearing. The lifting hook further comprises a connecting assembly connecting the lifting hook rod with the lifting hook body. The connecting assembly comprises anembracing type wedging sleeve and a lifting hook hoop arranged below the thrust self-aligning roller bearing. The lifting hook hoop is fixedly connected with the lifting hook rod through the embracingtype wedging sleeve. According to the provided lifting hook, the single-hook lifting weight is super large, and the single hook hoisting weight is 5,000 tons or above. Due to the fact that the lifting hook is split, the embracing type wedging sleeve and the hoop are connected to install the lifting hook body and the lifting hook rod together, and the novel split lifting hook is initiated in the world; the stress of the split lifting hook is reasonable, the dead load is small, the structural strength is high, the dead load of lifting hook sets is greatly reduced, and accordingly the operationcapability and operation efficiency of a floating crane are improved.

Description

technical field [0001] The invention relates to a large tonnage hook of an offshore floating crane, a kind of marine engineering equipment, in particular to a novel super large tonnage split hook made of high-strength materials, with a single hook lifting capacity of 5,000 tons and above. Background technique [0002] The hook is an important pick-up tool used to lift goods in the crane. It is widely used in port and ship operations, especially in the field of marine engineering floating cranes, such as offshore floating cranes and heavy lifting on offshore platforms. etc.; At the same time, the hook can also be used for various lifting tools, while the large-tonnage hook is mainly used for floating cranes in marine engineering. [0003] In the prior art, the hooks can be divided into split type and integral type according to the structural form. The split hook includes hook body, hook rod, hook nut, thrust spherical roller bearing and spherical roller bearing, etc. This f...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the defects that the traditional hooks have insufficient lifting capacity, short service life, and inability to withstand high-strength and high-frequency operations, and provide a new type of super-large-tonnage split-type hook made of high-strength materials. With a lifting capacity of 5,000 tons and above, it adopts the form of four claws, and two of the claws can lift more than 5,000 tons
