Description

Technical Field

[0001] The utility model relates to the technical field of formers for coiling materials, and more specifically refers to a coiling device for replacing steel wire ropes of skew bridge material cars of blast furnaces. Background Art

[0002] The hoisting feeding system is the main equipment of the blast furnace. After the material enters the blast furnace inclined bridge material car through the intermediate weighing hopper, it is pulled by the hoisting system to the furnace top receiving hopper for unloading. The wire rope of the hoisting system will wear out after a period of use. In order to meet the requirements of safe production, it needs to be replaced regularly. When replacing the hoisting wire rope, the new wire rope is fixed to the old wire rope at the end, and the old wire rope is pulled out through the hoisting system jog operation, and the new wire rope is wound into the hoisting system. During the whole process, the winding and stopping of the drum of the new wire rope are all manually stopped or wound, which poses a great safety hazard.

Finally, after the sleeve cools and its inner diameter shrinks, the sleeve and the shaft can be fastened together. The whole process takes more than an hour, which is not only cumbersome to operate on site, but also time-consuming, affecting on-site production efficiency. Utility Model Content
