Lifting appliance for box-type parts

Abstract

The invention discloses a lifting appliance for box-type parts. The lifting appliance comprises a lifting ring assembly for being hooked by a lifting hook and two lifting arms, wherein the two liftingarms are fixedly connected with the lower end of the lifting ring assembly, and are used for penetrating the box-type parts and can achieve lifting; a rotary adjusting assembly for adjusting liftingheight of the box-type parts by the lifting arms so as to keep the axis of the box-type parts horizontal is arranged on any one lifting arm. The lifting appliance for the box-type parts can effectively lift the box-type parts by single-person operation, threading and disassembly of a lifting tape are not needed, and thus, lifting efficiency can be improved, levelness of the box-type parts in the lifting process can be adjusted by rotating an adjusting assembly, stability of the box-type parts during lifting can be ensured, and thus, the box-type parts can be prevented from swinging back and forth in the lifting process, the safety factor can be improved, and universality of the lifting appliance is also greatly improved due to adjustability of the rotating adjusting assembly.

Description

technical field [0001] The invention relates to the technical field of mechanical hoisting, in particular to a hoisting tool for box parts. Background technique [0002] As the main body of the engine, the cylinder block connects each cylinder and the crankcase as a whole, and is the supporting framework for installing pistons, crankshafts and other parts and accessories. [0003] Large and medium-sized parts such as cylinder blocks need to be hoisted out of the equipment with lifting gear during the circulation and quality inspection of parts in different processes, but lifting gear for horizontal parts is relatively rare. At present, the most common existing technology is to use two slings to pass through box-like parts for hoisting. However, the use of two slings for hoisting requires manual passage through the cylinder block and other box-type components. During the hoisting process, one component needs to be disassembled and assembled twice, and the hoisting process re...

AI Technical Summary

Problems solved by technology

However, the use of two slings for hoisting requires manual penetration of box-like components such as the cylinder block. During the hoisting process, one component needs to be disassembled and assembled twice, and the hoisting process requires two people to cooperate to complete the efficiency is very low; At the same time, due to the poor rigidity of the sling, it is easy to swing back and forth when hoisting box parts, which easily leads to a low safety factor

[0004] Therefore, how to avoid the low efficiency and safety factor due to the traditional sling hoisting box parts is a technical problem that those skilled in the art need to solve at present
