Description

Special lifting device for long coupler Technical Field The invention relates to the technical field of lifting appliances, in particular to a lifting appliance device special for a long coupler. Background The coupling, also called coupling or back wheel, is a device used for coupling two shafts or shafts and a rotating member and transmitting motion and torque in mechanical engineering, and has the functions of offset compensation, buffering vibration reduction and overload protection. The structure of the coupling is usually composed of two halves, the shaft ends are connected through keys or tight fit, the coupling is suitable for connecting parts such as gears, pulleys and the like, and the coupling is divided into two main types of rigid couplings and flexible couplings. Rigid couplings require strict centering, including flange couplings, sleeve couplings, etc., flexible couplings are classified into inelastic element type (e.g., slider couplings, universal couplings) and elastic element type (e.g., elastic pin couplings, quincuncial couplings) which compensate for displacement, and the latter having cushioning properties. Currently, when transferring long couplings, it is often necessary to hoist them by means of hooks of shop trolleys (bridge cranes). However, in the prior art, for the handling operation of the long coupling, a method is generally adopted in which the long coupling is wound and bound by a steel wire rope for multiple times, and then a crane hook is connected with the steel wire rope, so that handling is implemented. The traditional lifting mode has a plurality of defects; For example, the operation process of binding the steel wire rope bundle is very complicated, an operator is required to wind and tie around the long coupler for many times, the labor intensity is high, the time is consumed, the operation efficiency is seriously affected, and secondly, the long coupler is smooth in surface and mostly cylindrical, the steel wire rope is bound only by virtue of friction force of the steel wire rope, the steel wire rope is very easy to slide relatively in the hoisting moment or the hoisting process, the steel wire rope is caused to slip from the end part or the middle part of the coupler, the hoisted object is in a falling risk, and the steel wire rope is inconvenient to use and has a great potential safety hazard.
