Shape, size and oxygen rifle match.
There is the sawtooth 16a being interspersed with reference to shown in Fig. 9 and Figure 10, on cutting profile 16.
One is provided with the side wall of cleaning seat 1 and above passive cutting mechanism 3 can detect oxygen rifle outer surface to clearly
The length detection mechanism 17 of distance between reason seat 1.
The effect of length detection mechanism 17 is, by detecting oxygen rifle surface to the distance between side wall of seat 1 is cleared up, so as to control
The output length of expansion bend 6 processed and the output shaft of cutting wheel regulator 15, control follower 7 and cutting wheel 13 and oxygen rifle 100 it
Between distance, prevent from excessively cutting the slag in oxygen rifle, cause oxygen rifle to be damaged.
In the present embodiment, with reference to shown in Fig. 3, length detection mechanism 17 includes the detection machine side walls hinged with cleaning seat 1
Frame 18, and the linear transducer 19 being fixed in the cleaning side wall of seat 1, the described connecting detection frame 18 of linear transducer 19,
Detection wheel 20 is rotatably connected in the end of detection frame 18, in rolling when detection wheel 20 contacts with the slag 101 on oxygen rifle surface
State, monitoring in real time is realized, linear transducer 19 is prior art.
In step, untapped that oxygen rifle is placed in two opposite slag removing devices, detection wheel 20 is pasted with oxygen rifle surface
Oxygen rifle surface is obtained to cleaning the distance between side wall of seat 1 by linear transducer 19 after conjunction, as initial value D0,
In stepb, after oxygen rifle surface adhesion slag, detection wheel 20 is passed after being bonded with the slag on oxygen rifle surface by length
Sensor 19 obtains slag surface to the distance between side wall of seat 1 is cleared up, and as detected value D1, it is D1-D0 to determine thickness of steel slag.
Passive cutting mechanism 3 includes the second fixed seat 21, and the second fixed seat 21 is fixedly connected with the cleaning side wall of seat 1, stretched
Device 6 is fixed in the second fixed seat 21, and described expansion bend 6 has can be along reciprocating output shaft.In the present embodiment, stretch
Contracting device 6 is oil cylinder, and output shaft can be controlled to export length.
With reference to shown in Fig. 5 and Fig. 6, the second fixed seat 21 is provided with detection bracket 22, and the top of detection bracket 22 is oblique with being oriented to
Face, described detection bracket 22 are fixedly connected with the output shaft of expansion bend 6 so as to be moved back and forth with output shaft, detect frame 18
It is pressed on detection bracket 22, the slideway 23 to be matched with the detection shape of bracket 22 is provided with the second fixed seat 21.Work as detection
When bracket 22 moves back and forth, detection frame 18 is rotated and moved up and down, and drives detection wheel 20 closer or far from oxygen rifle 100.
With reference to shown in Fig. 4, chute 25 is provided with the second fixed seat 21, expansion bend 6 is fixed in chute, and follower 7
Size is matched with chute 25 so as to make follower 7 extend outside chute 25 or be received into chute 25.
Preferred scheme, in addition to step D, repeat step A-C make initial value D0 be equal to measured value D1.Determine that slag is scraped completely
Remove.
The most important advantage of slag removing device is：Cutting wheel 13 is fast to slag cutting speed, but slag surface in it is concavo-convex not
It is flat-shaped, and by the secondary cut of follower 7 after, follower 7 makes slag or oxygen rifle surface forms smooth face, so that oxygen rifle
Operating efficiency is improved.
The operation principle of slag removing device is：
Cleaning seat 1 has bottom surface and side wall, and the first fixed seat 4 is fixed on the bottom surface of cleaning seat 1, and the second fixed seat 21 is solid
It is scheduled in the side wall of cleaning seat 1.
With reference to shown in Figure 14, oxygen rifle 100 connects oxygen rifle lifting rope 102, and oxygen rifle lifting rope 102 connects hoist engine or manually dragged
It is dynamic, the uneven thickness of slag 101 of the outer wall of oxygen rifle 100, therefore need to control cutting thickness during cutting, cutting otherwise can be caused excessive
Or cutting is incomplete, can all influence the use of oxygen rifle.
In the present embodiment, when oxygen rifle 100 is not coming into operation, should first check oxygen rifle outer wall and cleaning seat 1 side wall it
Between distance, the detection of distance obtained using linear transducer 19, and concrete operations are：Oxygen rifle 100 is placed in two opposite oxygen
Rifle removes slag between method, each oxygen rifle remove slag method structure as described above, expansion bend 6 first acts, make follower 7 and oxygen rifle
100 fittings, the maximum advance value T0 of expansion bend 6 is obtained, detection bracket 22 moves with expansion bend 6, and detection frame 18, which rotates, makes inspection
Measuring wheel 20 is bonded with oxygen rifle outer wall, and linear transducer 19 obtains an oxygen rifle outer wall with clearing up the first of the distance between the side wall of seat 1
Initial value D0, after oxygen rifle uses a period of time, outer wall can produce slag 101, it is necessary to carry out scraping slag cleaning.
Likewise, repeating the above steps, drive follower 7 to be bonded slag surface with the action of expansion bend 6, further make
Detection wheel 20 is bonded slag surface, and the value that linear transducer 19 obtains detected value D1, D0-D1 is exactly the thickness of slag.
The oxygen rifle for making to measure drops to the position coordinated with active cutting mecha 2, and cutting wheel regulator 15 is acted, driven
Driver mounting seat 10 works close to oxygen rifle 100, driver 11, drives cutting wheel 13 to rotate, slag is cut, cut
During, the perseveration of wheel regulator 15 is cut, makes cutting wheel 13 when cutting slag close to oxygen rifle, so as to fully erased oxygen rifle
The slag on surface, D0-D1 value is exactly that cutting wheel 13 cuts to the value that cutting is completed, the shifting of cutting wheel 13 by fitting slag
On the one hand dynamic distance can be controlled by cutting wheel regulator 15, on the other hand can also be entered by setting scale on cleaning seat 1
Row control.
In the cutting process of active cutting mecha 2, length detection mechanism 17 persistently detects to thickness of steel slag, is follow-up
The thickness that active cutting mecha 2 cuts slag provides foundation.
By above-mentioned scheme, oxygen rifle continuous decrease, active cutting mecha 2 is cut the slag on oxygen rifle surface, until
Whole oxygen rifle all carries out active slagging-off.
It is in next step passive slagging-off, cutting wheel regulator 15 first drives cutting wheel 13 to depart from oxygen rifle surface, and expansion bend 6 is dynamic
Make, driving follower 7, the maximum advance distance due to having measured expansion bend 6 before is T0 close to oxygen rifle, therefore is controlled flexible
The advance value of device 6 is not more than T0, after follower 7 is bonded oxygen rifle surface, stair-stepping cutting edge 8 namely fitting oxygen rifle table
Face, oxygen rifle lifting rope 102 pull oxygen rifle 100 to rise, and cutting edge 8 is progressively struck off processing to the slag of the remained on surface of oxygen rifle 100,
Rise to oxygen rifle and finish.
It will be appreciated by those skilled in the art that oxygen rifle 100 can as stated above, lifting is multiple repeatedly, carries out at slagging-off
Reason.
