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.
