Novel cylindrical object hoisting tool

Abstract

The utility model relates to the technical field of lifting appliances, in particular to a novel cylindrical object lifting tool which comprises a lifting rod, a lifting ring is fixedly mounted at the upper end of the lifting rod, and a threaded cylinder is in threaded connection with the lower end of the lifting rod. At the moment, the clamping plate and the lifting rod move upwards together, the clamping plate is opened, the arc-shaped clamping face of the clamping plate is connected with the surface of the cylindrical object and tightly supports the surface of the cylindrical object, due to the fact that lifting equipment continuously exerts upward force, the clamping plate is kept in an opening state all the time, the cylindrical object can be effectively prevented from sliding and falling off in the lifting process, and the service life of the cylindrical object is prolonged. And after the cylindrical object is hoisted to a set position, the hoisting equipment stops applying upward pulling force, and the clamping plate and the hoisting rod move downwards together, so that the clamping plate is contracted and is not in contact with the cylindrical object any more, namely, the hoisting tool is taken out, the labor intensity of workers is relieved, and the working efficiency is improved.

This method occupies a large space when hoisting because the object is placed horizontally, and it is not suitable for hoisting in a narrow indoor space. The hoop hoisting method is to clamp the surface of the cylinder with a hoop hoisting device and use the friction force of the clamping to hoist the cylinder. However, when hoisting the cylinder, there are often problems such as insufficient stability, easy sliding, and falling off. On the other hand,
