Description

Converter trunnion ring replacing options

Technical field

The present invention relates to maintaining equipments technical field more particularly to a kind of converter trunnion ring replacing options.

Background technology

The volume and quality of large and medium-sized converter trunnion ring are all very big, high such as the converter trunnion ring diameter about 10m of capacity 210T converters About 2.5m mass about 160T;And the converter trunnion ring of capacity 300T converters is just huger, backing ring quality is close to 300T.It is huge to hang It packing quality and hangs rise and needs hanging device using big elevating capacity, it is also necessary to use some rational hanging methods.One As mini-medium BOF plants be mostly used upright method of hull section construction lifting, large and medium-sized converter also adopts due to being limited by lifting machine ability, workshop condition etc. Method lifting is moved into upside-down method of hull-section construction or hydraulic lifting.

Applicant encounters problems in certain converter trunnion ring replacement process:As shown in Figure 1, the support of the converter trunnion ring The spacing that trunnion outer length is more than the Liang Ge manufacturers column being located in front of it is enclosed, converter trunnion ring can not be removed directly.By workshop The limitation of condition need to remove mill building frame and equipment using traditional mounting technique, wait for again restoring after converter trunnion ring is replaced, Quantities is huge, of high cost, time-consuming and laborious, and difficult to realize.

Invention content

The technical problem to be solved by the present invention is to:A kind of converter that can move in and out converter trunnion ring from stenosis is provided Backing ring replacing options.

In order to solve the above problem the technical solution adopted is that:Converter trunnion ring replacing options include the following steps:

A, it is arranged above the fixed ROTATION CABLES at least three upper ends in converter trunnion ring;

B, the hoisting rope of the lifting equipment above converter trunnion ring is connect with converter trunnion ring, is sling and is turned using lifting equipment Stove backing ring;

C, ROTATION CABLES is connect with converter trunnion ring;On converter trunnion ring circumferencial direction, ROTATION CABLES is inclined and each rotation It is identical with tilt quantity to turn rope inclined direction;

D, decline hoisting rope, ROTATION CABLES is made to suspend converter trunnion ring in midair;On converter trunnion ring circumferencial direction, ROTATION CABLES is automatic Backswing drives converter trunnion ring rotation;

E, rise hoisting rope and sling converter trunnion ring on a small quantity, moving ROTATION CABLES makes it tilt again, then declines lifting Rope, automatic backswing drives converter trunnion ring rotation to ROTATION CABLES again;It so repeats, until converter trunnion ring can be in front of it Pass through between Liang Ge manufacturers pillar;

F, converter trunnion ring is removed between Liang Ge manufacturers pillar;

G, new converter trunnion ring is moved between Liang Ge manufacturers pillar;

H, new converter trunnion ring is made to reversely rotate to installation direction to the identical method of E steps using B;

I, converter trunnion ring is put down.

It is further:The quantity of ROTATION CABLES is four, four ROTATION CABLESs circumference centered on converter trunnion ring axis It is uniformly distributed.

The beneficial effects of the invention are as follows:Method using the present invention, converter trunnion ring can cannot lead to from art methods The stenosis crossed is removed and is moved into, and is solved the problems, such as to be limited by workshop condition in converter trunnion ring replacement, has been also equipped with operation letter It is single, it is safe, it is highly practical, it is easily mastered, province's wealth is laborsaving time saving, the very notable advantage of economic benefit.

Specific implementation mode

The present invention is further described with reference to the accompanying drawings and detailed description.

As shown in Figures 1 to 6:Converter trunnion ring replacing options include the following steps:A, converter trunnion ring 1 be arranged above to The fixed ROTATION CABLES in few three upper ends 3;B, by the hoisting rope 21 and converter trunnion ring 1 of the lifting equipment 2 of 1 top of converter trunnion ring Connection, converter trunnion ring 1 is sling using lifting equipment 2;C, ROTATION CABLES 3 is connect with converter trunnion ring 1;1 circumference side of converter trunnion ring Upwards, ROTATION CABLES 3 is that inclined and each 3 inclined direction of ROTATION CABLES is identical with tilt quantity;D, decline hoisting rope 21, make rotation Turn rope 3 and suspends converter trunnion ring 1 in midair;On 1 circumferencial direction of converter trunnion ring, 3 automatic backswing of ROTATION CABLES drives converter trunnion ring 1 to rotate; E, rise hoisting rope 21 and sling converter trunnion ring 1 on a small quantity, moving ROTATION CABLES 3 makes it tilt again, then declines hoisting rope 21, automatic backswing drives converter trunnion ring 1 to rotate to ROTATION CABLES 3 again;It so repeats, until converter trunnion ring 1 can be from its front Liang Ge manufacturers pillar 4 between pass through;F, from removal converter trunnion ring 1 between Liang Ge manufacturers pillar 4;G, by new converter trunnion ring 1 It is moved between Liang Ge manufacturers pillar 4;H, using B to the identical method of E steps, new converter trunnion ring 1 is made to reversely rotate to installation Direction;I, converter trunnion ring 1 is put down.

In step A, the fixed position of 3 upper end of ROTATION CABLES should have enough intensity, and 3 upper end of ROTATION CABLES can connect On mill building frame crossbeam.In workshop, typically with lifting equipment, lifting equipment 2 can be that originally some rises in workshop Heavy equipment;Can also be to aim at converter trunnion ring 1 to replace and the coaster on mill building frame crossbeam is arranged;It can also be crane.This The core point of invention is the rotation of converter trunnion ring 1, and the translation of converter trunnion ring 1 is the prior art, therefore the present invention does not chat in detail It states.

ROTATION CABLES 3 should be able to reliably suspend converter trunnion ring 1 in midair, and 1 upper and lower directions of converter trunnion ring is avoided to swing, therefore rotate The quantity of rope 3 is at least three.The quantity of ROTATION CABLES 3 of the present invention is preferably four, and four ROTATION CABLESs 3 are with converter trunnion ring Circumference uniform distribution centered on 1 axis.
