Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1, Fig. 2 clearly illustrate structure and application site, the application structure of stationary installation embodiment of the present invention.As shown in the figure, this stationary installation embodiment comprises multiple support 2, adjustment structure.Preferably, support 2 is in shaft-like, and adjustment structure is bolt 5.Specifically, the first end of support 2 is fixed on normal furnace stay 1, and the second end extends, for bolt 5 being arranged on the outside of protecting sheet 4 to the outside of the protecting sheet 4 that furnace stay 3 to be replaced is fixed.The second end of support 2 is located at by bolt 5, and free end (small end) is supported in the outside of protecting sheet 4, for fixing protecting sheet 4, and by rotating, can regulate the pressure put on protecting sheet 4.
In order to not produce the sense repeated, below in conjunction with the application process of stationary installation embodiment of the present invention, its structure is described further.
First, according to furnace stay 3 position to be replaced, the protecting sheet 4 need fixed when determining to change furnace stay 3 to be replaced.During normal production, protecting sheet 4 is fixed by the furnace stay to be replaced 3 be close to outside it, and after certain hour, furnace stay 3 to be replaced is out of shape, and is difficult to effectively support protecting sheet 4, fix, and needs to change, and in Renewal process, reply protecting sheet 4 is fixed, and avoids it to move.
The first end of four supports 2 is fixed on the normal furnace stay 1 of furnace stay 3 both sides to be replaced.Wherein, the first end of every two supports 2 is fixed on the two ends of same normal furnace stay 1, and preferably, support 2 is in long strip-board shape structure, and first end is welded on the side of normal furnace stay 1, to avoid taking larger space.Second end of four supports 2 is then outside corresponding four bights being arranged on protecting sheet 4.Need to illustrate in advance, before support 2 is welded on normal furnace stay 1, the second end of support 2 has been provided with screw (unmarked).
In the screw of support 2 second end, screw in bolt 5, and the free end end face of bolt 5 is supported on the outer side of protecting sheet 4, thus reach the object of fixing protecting sheet 4.
Now, i.e. replaceable furnace stay to be replaced 3.Because bolt 5 tightly support protecting sheet 4, protecting sheet 4 can not be moved, be out of shape.
Furnace stay 3 to be replaced takes off bolt 5 after changing.
Support 2 on normal furnace stay 1 is cut, removes.
When protecting sheet 4 fixed by bolt 5; after furnace stay 3 to be replaced is removed; certain slight movement or distortion may be there is in protecting sheet 4; in order to whether position, the shape that can detect protecting sheet 4 change; the present embodiment can also comprise the multiple infrared equipment (not shown) for measuring distance; the indication mechanism that infrared equipment comprises feeler mechanism, is connected with feeler mechanism, detection data are sent to indication mechanism by feeler mechanism.
During application, multiple infrared equipment is fixed on the different positions on normal furnace stay 1, before changing furnace stay 3 to be replaced, measures the distance of different reference point on an infrared equipment to protecting sheet 4, and record.After furnace stay 3 to be replaced takes off; if the position of protecting sheet 4 is moved; when rotating bolt 5 drives protecting sheet 4 to set back; infrared equipment detects the distance of reference point in real time; until the reference point distance detected in real time equals the reference point distance of original record, can ensure that the position of protecting sheet 4 is identical with the position changed before furnace stay to be replaced like this.
The support process of normal furnace stay of the present invention 3 pairs of protecting sheets 4 is:
The cross section of normal furnace stay 3 is " work " character form structure; the structure of normal furnace stay 3 is divided into the first back up pad, the second back up pad and web plate; the shape of protecting sheet 4 is " work " glyph shape; under normal circumstances; first back up pad of normal furnace stay 3 is used for propping up protecting sheet 4, carries out spacing to protecting sheet 4.
As shown in Figure 1 and Figure 2, below specific works process of the present invention is described in detail:
First, determine which furnace stay is furnace stay 3 to be replaced;
Secondly, according to furnace stay 3 to be replaced, the protecting sheet 4 protecting this furnace stay 3 to be replaced is determined; Weld two supports 2 in the web plate position of the normal furnace stay 1 of furnace stay 3 both sides to be replaced simultaneously, as shown in Figure 3, support 2 is a plate construction, the first end 22 of support 2 is welded to connect with the web plate of normal furnace stay 1, parallel end 21 and the protecting sheet 4 of support 2 are set in parallel, have a threaded hole at the second end 23 place of support 2, this threaded hole is vertical setting with the parallel end 21 of support 2, the screw hole of bolt 5 and the second end 23; By screwing bolt 5, the free end of bolt 5 is made to hold out against protecting sheet 4, specifically holding out against step is: four supports 2 respectively with two ends, top and the following justify align of " work " glyph shape of protecting sheet 4, the free end of four bolts 5 holds out against the two ends, top of " work " glyph shape of protecting sheet 4 and following two ends respectively simultaneously;
Now, i.e. replaceable furnace stay to be replaced 3.Because bolt 5 tightly support protecting sheet 4, protecting sheet 4 can not be moved, be out of shape.
Furnace stay 3 to be replaced takes off bolt 5 after changing.
Support 2 on normal furnace stay 1 is cut, removes.
As shown in Figure 3, the width of the first end 22 of support 2 of the present invention is greater than the width of the second end 23, like this design can when support 2 being welded on normal furnace stay 1 handled easily; Moreover the end of the second end 23 of support 2 of the present invention is semicircular arc; like this can so that arrange threaded hole; be benchmark when arranging threaded hole with semi arch, the thickness as outside of the threaded hole obtained is impartial, reaches the object of stress equalization when bolt 5 pairs of protecting sheets 4 exert a force.
In sum, the present invention, when changing furnace stay, can effectively substitute furnace stay and fix protecting sheet, easy to operate, and structure is simple, can also apply different pressure, regulate its position as required to protection.Installation site does not affect the normal traveling of coke-oven locomotive simultaneously, does not affect coke oven and produces.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
