Abstract

The invention discloses a lifting hook and a crane, relates to the technical field of engineering machinery, and solves the technical problem that in the prior art, the lifting hook replacement time is long. The lifting hook comprises a lifting hook body, a detachable connection structure and one or more auxiliary demountable pulley blocks, wherein the lifting hook body comprises a hook head part and a pulley block part; the pulley block part comprises two pulley yoke boards being opposite in position and a pulley arranged between the two pulley yoke boards; the hook head part is connected with the pulley yoke boards; each auxiliary demountable pulley block comprises a mounting rack and a pulley mounted in the mounting rack; each mounting rack comprises two mounting rack boards being opposite in position and a connection rack body connected between the two mounting rack boards; mounting rack boards and/or connection rack bodies are detachably connected with the pulley yoke boards through the detachable connection structure. The crane comprises the lifting hook. The lifting hook and the crane have the advantages that the replacement time of the lifting hook is shortened, and thus the heavy load lifting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a suspension hook and a crane provided with the suspension hook. Background technique [0002] The hook is the hook used by the crane when lifting heavy objects. The hook is provided with a hook head and a pulley block, the hook head is used to hang heavy objects, and the pulley block is used to resolve the tension of a single hoisting wire rope. [0003] The suspension hook of the existing crane is an integral structure, the pulley shaft is long, the bending stress is too large during load bearing, and the bearing capacity is low. In order to meet the requirements of diversified operating conditions of large-tonnage cranes, a crane is equipped with two or more hooks. [0004] 1. The large hook is used to lift heavy objects. The hook is equipped with multiple pulleys, the wire rope has multiple ratios, and the lifting performance is strong. At the same time, the h...
