Technical Field

The invention relates to the technical field of construction of a reformer, in particular to a lifting appliance for multi-group combined lifting of reformer furnace tubes and a using method thereof.

Background

The inside of a radiant section furnace body of the converter is composed of hundreds of catalytic furnace tubes filled with catalysts, the length of the furnace tubes is about 15 meters generally according to the furnace body and the capacity, the diameter range is about 100 to 200mm in the front and the back, the thickness of the tube wall is about 10mm, and the bending deformation is not allowed in the lifting process. If single-point hoisting is adopted, because the length of the furnace tube is long, the furnace tube is easy to deform and damage the furnace tube in the hoisting process, so that the common hoisting of the furnace tube adopts double hooks to hoist a single furnace tube, the furnace tube is adjusted to be vertical to the ground after being hoisted to a certain height, the lower part hoisting tool is removed, and the pipeline is hoisted to the upper part of the pipe hole by a crane and vertically penetrates into the pipe hole. The method can only hoist one catalytic tube each time, and the hoisted lifting appliance needs to be repeatedly disassembled and assembled, particularly the lower lifting appliance needs to be disassembled in the air, so that the working efficiency is low, and the danger is high.

Disclosure of Invention
