Lifting hook and crane provided with same

Abstract

The invention belongs to the field of machine manufacturing of cranes, and particularly relates to a lifting hook and a crane provided with the lifting hook. The lifting hook is characterized in that a groove is formed in a lower position, relative to a baffle installation base, of a lifting hook body; the lifting hook further comprises a baffle which consists of a pivot end and a free end, wherein the pivot end is pivoted with the baffle installation base, the pivot end is hollow and is internally provided with parallel channels, a backstop bump is arranged at an opening of each channel, and at least one spring is arranged at the pivot end close to the baffle installation base; one end of the free end is sleeved with the pivot end and is connected with the springs, locking baffles are arranged on both sides of the free end and are matched with the parallel channels, and a through hole is formed in the other end of the free end; a slot is formed outside the hook part of the lifting hook body and is matched with the through hole in the free end. The lifting hook provided by the invention has the advantages that the lifting hook is novel in concept and compact and reasonable in structure, and the free end of the baffle can slide in the pivot end; the baffle has the anti-skid function; a lifting rope is convenient to be hoisted into the lifting hook or taken from the lifting hook, so that the time and labor are saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of crane machinery manufacturing, in particular to a hook and a crane with the hook [0002] crane. Background technique [0003] Commonly used suspension hooks in the prior art have an anti-off function to prevent the suspension rope from deviating from the inner space for accommodating the suspension rope. A baffle mounting seat is installed on the opening side of the hook body connection end of the hook. The baffle includes a pivot end and a free end oppositely arranged. The pivot end is installed on the baffle mounting seat through a pin shaft, and the free end can be wound around the pin. When the shaft rotates, the torsion spring acts on the hook body and the baffle respectively. Under the action of the torsion spring, the free end of the baffle is closely attached to the inner wall of the hook body, so that the baffle closes the opening and prevents the rope from decoupling. The disadvantage is that since the...

Problems solved by technology

The disadvantage is that since the baffle is tightly attached to the inner wall of the hook body, when taking out or replacing the sling, it is necessary to manually press the baffle toward the inner space of the hook body, that is, when taking out or loading the sling At the same time, in order to open the opening of the hook, it is necessary to apply a force to the baffle to resist the torsional force exerted by the torsion spring on the baffle; the sling is heavy and requires two people to operate, which is time-consuming and laborious, and the work efficiency is low
