Description

Circulating pump maintenance balance hanger

technical field

The utility model relates to the field of circulation pump maintenance, in particular to a balance hanger for circulation pump maintenance.

Background technique

Existing circulating pump hangers use tripods or assembled gantry cranes, but because each heat exchange station has multiple circulating pumps, it is necessary to frequently change the hoisting position when disassembling and assembling circulating pump motors and pump parts with tripods or assembled gantry cranes. Frequent assembly of hangers is difficult, time-consuming and labor-intensive.

Moreover, tripods and assembled gantry cranes can only lift objects vertically. If you want to move the maintenance parts (such as motors) to an open position for easy maintenance, 2-3 people are required to stabilize the legs of the hanger, push the lifting parts manually, and loosen the guide chain. If it is released slowly, it is easy to cause the hanger to become unstable, which poses a great safety hazard.

In addition, when the tripod and the assembled gantry crane are used to overhaul the circulating pump, all types of equipment are hoisted and overhauled by a guide chain and a wire rope. There are no special tools, and the overhaul efficiency is low.
