The invention provides a lifting appliance for rapidly lifting a piston and a using method thereof, and belongs to the technical field of lifting. Comprising a base body, a vertically-through mounting inner cavity is formed in the base body, a plurality of supporting blocks are evenly distributed on the periphery of the lower end of the base body, the supporting blocks are movably connected with the base body, a top column is vertically arranged in the mounting inner cavity of the base body in a penetrating mode, and a cone structure larger than the radial size of the mounting inner cavity is arranged at the lower end of the top column. The lower end of the base body, the supporting block in the natural drooping state and the cone structure at the lower end of the jacking column can penetrate through a piston pin hole C of the piston in a clearance mode, and when the cone structure is driven by the jacking column to move upwards, the supporting block is opened to make contact with the inner wall face of the piston pin hole C of the piston. A safety locking structure enabling the cone structure to continuously keep the supporting block open is arranged on the upper portion of the top column. According to the invention, the collision and scratch risks in the piston hoisting process are reduced, the hoisting potential safety hazard is avoided, rapid positioning and safe and efficient hoisting are realized, and the transfer and processing quality is improved.

    提供一种活塞快速吊装用吊具及其使用方法,属于吊装技术领域。包括基体,基体内部设有上下贯通的安装内腔,基体的下端部一周均布有多个支撑块,支撑块与基体为活动连接,基体的安装内腔中上下贯穿设有顶柱,顶柱下端设有大于安装内腔径向尺寸的锥体结构,基体下端部、自然下垂状态时的支撑块、以及顶柱下端的锥体结构均能从活塞的活塞销孔C中间隙穿过,锥体结构在顶柱的带动下上移时将支撑块撑开与活塞的活塞销孔C的内壁面接触,顶柱上部设有使锥体结构持续保持支撑块撑开的安全锁定结构。本发明减少活塞吊装过程中的磕碰划伤风险,避免吊装安全隐患,实现快速定位及安全高效吊装,提高转运及加工质量。
