Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of structure simple, safe and reliable, operate stable, without the need to the blast furnace roof head sheave installation and locating method of follow-up adjustment.
The technical solution used in the present invention is:
A kind of blast furnace roof head sheave installation and locating method, by steel wire winding on main winch cylinder, is arranged on blast furnace roof by head sheave; Main winch cylinder drives steel rope to be connected with feeding cart by head sheave, and the head sheave installation steps of blast furnace roof are as follows:
A, installation main winch cylinder, determine that wirerope-winding is in the left-limit position of main winch cylinder and limit on the right-right-hand limit position;
B, according to feeding cart orbital position, determine the steel rope that head sheave top contacts with steel rope and head sheave contacting points position;
C, according to steel rope at the left-limit position of main winch cylinder and limit on the right-right-hand limit position and head sheave top and the steel rope contacting points position determination steel rope winding pendulum angle at main winch cylinder;
D, angular bisector according to wirerope-winding pendulum angle determination pendulum angle, the end position at main winch cylinder and the angle of steel rope and head sheave contacting points position determination steel rope pivot angle bisector and winch cylinder axis according to steel rope pivot angle bisector and steel rope;
E, head sheave center line to be arranged along steel rope pivot angle bisector;
F, by bolt of rear end plate, head sheave to be fixed on day wheel support.
The beneficial effect of hinge structure of the present invention:
Blast furnace roof head sheave installation and locating method of the present invention, improves the setting accuracy of blast furnace roof head sheave, reduces the danger of follow-up aloft work, reduce the danger that steel rope stings head sheave edge, improve the life-span of steel rope and head sheave, save engineering cost, ensure blast fumance safety.
