Construction method for sliding and replacing whole body of jacking and revolving bearing of revolved body of stacker-reclaimer

Abstract

The invention discloses a construction method for sliding and replacing a whole body of a jacking and revolving bearing of a revolved body of a stacker-reclaimer, and belongs to the technical field of replacing components of the stacker-reclaimer in iron-smelting raw material yards. The construction method comprises the following steps: before machine halt construction, firstly manufacturing jack supporting beams, safe piles and a stirrup, mounting the jack supporting beams, and mounting the stirrup; selecting hydraulic jacks, and erecting the selected hydraulic jacks; sealing the whole body of the revolved body of the stacker-reclaimer, manufacturing a sliding device of the revolving bearing, mounting the manufactured sliding device, and dismounting and removing components which have influence on the horizontal sliding of the revolving bearing; sliding the whole body of the jacking and revolving bearing of the revolved body, replacing the slid whole body of the jacking and revolving bearing of the revolved body, and mounting the components which have influence on the horizontal sliding of the revolving bearing. The construction method has the advantages that the problems that a large-scale vehicle type crane needs to be used during replacing the revolving bearing of the stacker-reclaimer in the iron-smelting raw material yards, the construction time is long, the occupied site is large, the construction cost is high and influence on the production is great; the method is simple and easy to operate, and the construction cost is reduced; the construction site is reduced, the whole construction time of jacking and sliding is shortened, and influence on the production is reduced; double safety facilities of the sealed whole body and the safe piles are adopted, so that the safety guarantee is supplied.

Description

technical field [0001] The invention belongs to the technical field of parts replacement of stackers and reclaimers in iron-making raw material yards, and in particular relates to a construction method for the integral lifting and sliding replacement of slewing bearings of the stacker and reclaimer rotator, which is suitable for complex construction environments and difficult disassembly and hoisting The construction project for the replacement of slewing bearings of large-scale slewing machinery and equipment. Background technique [0002] The stacker and reclaimer in the iron-making raw material yard mainly has two functions. The first is stacking, that is, unloading the raw materials conveyed by the raw material conveyor belt and stacking them in the raw material yard; On the blast furnace raw material conveying belt, the raw material is transported to the blast furnace through the belt, so the stacker and reclaimer plays an extremely important role in the raw material su...
