Abstract

The invention discloses a hoisting device for building blast furnaces. The technical schemes of the invention comprise that: the hoisting device is provided with an annular hanging beam and a horizontal hanging beam; the annular hanging beam is arranged horizontally and the annular hanging beam is supported by platforms which are fixed to a shell of a blast furnace and contact with the circumference of the annular hanging beam; the horizontal hanging beam has an elongated strip shape and is arranged horizontally below the annular hanging beam, and a centre portion of the horizontal hanging beam has an articulated connection with a centre portion of the annular hanging beam through a center hinge axle; two end portions of the horizontal hanging beam are arranged on an annular track of the annular hanging beam through circling pulleys; and a trolley is arranged on a track of the horizontal hanging beam through a pulley of the horizontal hanging beam. The hoisting device can realize that materials are swung safely at different height levels. Compared with the prior arts, the hoisting device of the invention has the advantages that: manual workload is reduced greatly; a building construction period is shortened by nearly 50%; labor efficiency is improved; material damages are avoided during construction processes; economic benefit is improved; and type selecting scopes of furnace bottom materials and hearth materials are extended.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry production equipment, and relates to furnace building equipment used in the construction of blast furnaces in iron and steel industry production, more specifically, the invention relates to blast furnace building hoisting equipment. Background technique [0002] At present, when building a small and medium-sized blast furnace, due to the limitation of the internal space of the blast furnace, the transportation of building materials in the furnace is mostly realized by manual or single-girder electric hoist (two degrees of freedom). Due to the restriction that the electric hoist can only move in a two-degree-of-freedom plane on the straight hanging beam, the material needs to be dragged manually, which is labor-intensive, and cannot meet the requirements of the ironmaking process for large-scale masonry materials at the bottom of the furnace, and the material is damaged High rate; se...
