Description

The lance holder that has multiple tolerance chuck head
Technical field
The lance holder that the gas ejector pipe that has chuck that the present invention relates to adopt in metallurgical and Iron And Steel Industry is used, it has mounting block and clamping element, the latter is equipped with a Sealed casing pipe, and Sealed casing pipe is clamped the gas ejector pipe of insertion and made it sealing with this by means of this mounting block.
Background technology
The lance holder that has chuck and anti-residue reflux (Schlackenruecklaufsicherung) or fireproof tempering device is used for supporting reliably the needed gas ejector pipe of refining, on the other hand, for example when converting process finishes or interrupt, do not allow the residue that refluxes arrive oxygen intake.According to DE23 27 595C, a gas-pervious sintered metal sheet that prevents that residue from refluxing was set nearby before oxygen hose.This method that refluxes with mechanical means blocking-up residue always can not satisfy institute's requirement, particularly in the time must using a large amount of oxygen, because at this moment sintered metal sheet can cause difficulty naturally.At this moment, the valve system that is arranged on the front is born the function that prevents that residue from refluxing equally, closure when wherein the tightness system of this valve above it is set burnt out because residue refluxes.The gas ejector pipe that inserts lance holder has the chuck that is arranged on clamp wherein with one and keeps.This clamp is fixed on gas ejector pipe in the insertion lance holder by the influence of this clamp tooth.A Sealed casing pipe is set in the back of this clamp, and it makes a difference by the pipe that inserts, and at this moment can be out of shape, and makes it to be attached to tightly the outside of gas ejector pipe.This action of being close to by the sealing casing deformation at first has individual shortcoming, and it may cause the sealing sleeve pipe to be bonded on the gas ejector pipe by baking, to such an extent as to the remainder of gas ejector pipe is difficult to or can only could takes out with Sealed casing pipe when clamp is opened.The special construction of this problem and this clamp brings such shortcoming, and promptly lance holder separately must adapt to quite exactly at its diametrically and remain the gas ejector pipe diameter that pushes and keep.Not only use the lance holder that can hold and fix pipe made in Great Britain now, and use the lance holder that can hold gas ejector pipe with metric size.At this moment, have only very little tolerance could pass through the motion and the last motion by Sealed casing pipe again of this clamp, this tolerance is roughly in the scope at 0.2mm under situation mostly.Because this gas ejector pipe is a kind of consumptive material, enterprise has to purchase the pipe that diameter is an inch size at last, purchase the pipe that diameter is a metric size again, this brings problem for workers, because generally they are instructed to purchase the lance holder that can accept pipe diameter seldom.This will cause always occurring damaging and accidents happened, can damage important lance holder part for fixing and sealing because insert too small or excessive diameter when operation, makes that this lance holder no longer is dynamical.Because oxygen is sent to liquation and gas ejector pipe is generally must be correspondingly crooked for this reason by these gas ejector pipes, so particularly when gas ejector pipe skids off or when other problems occurring, liquid steel entail dangers to operator.Even operator have working suit and safety helmet correspondingly to be protected, yet regrettably, this does not have enough provide protections for liquid steel, to such an extent as to always work accident may appear again and again.
Summary of the invention
The objective of the invention is to, provide a kind of to the gas ejector pipe of multiple size, at the same time multiple as far as possible size gas ejector pipe simultaneously fully reliable operation, and lance holder that can fine operation.
According to the present invention, this purpose is achieved by following measure, the mounting block that promptly surrounds the gas ejector pipe that is inserted is provided with the inclination start-up portion, distribute on the whole circumference can with the vertical direction of gas ejector pipe longitudinal axes on the pressure piece that moves on this inclination start-up portion, lead, and these pressure pieces are had the influence of the clamping element of the pressure slope corresponding with the inclination start-up portion.
By means of the lance holder that forms like this, what at first can realize is, particularly when the operation clamping element, clamping element is shifted onto on the mounting block when the operation chuck or here, accurately and reliably keep the gas ejector pipe inserted, wherein with clearly defined objectively fix exactly by pressure piece.Simultaneously unclamp Sealed casing pipe with this.Thereby guarantee that the gas ejector pipe that has inserted is as long as can also therefrom take out once more by cautiously operating clamping element.But it all obtains fixing reliably in the entire operation process of gas ejector pipe, and wherein the measure that also will describe by other back prevents that the sealing sleeve pipe from being toasted adhesion, although itself is equipped with a kind of diameter, also can use the gas ejector pipe of different size.The support scope of different gas ejector pipe diameters tilted start-up portion and correspondingly the clamping element of structure limit, still at this moment can dwindle the lance holder scantlings of the structure greatly.According to design of the present invention, to decide on the structure of lance holder, range of tolerable variance is roughly brought up to 0.5-3.00mm.At the gas ejector pipe of present use, must use according to a large amount of lance holders of size ruling separately, and so the number of gas ejector pipe can reduce to present 6-7 kind.This point is realized by following measure, promptly when the gas ejector pipe that is set size at separately lance holder is pushed, movably pressure piece works and becomes effective immediately, and when the excircle of gas ejector pipe hour, still can fix, because at this moment movably pressure piece only just becomes after the corresponding mobile stroke effectively, and fixing gas ejector pipe.
According to a kind of useful design of the present invention, these pressure pieces all shape are identical and side by side move along the wall portion of pressure slope towards gas ejector pipe.Along with pushing of separately gas ejector pipe, when the diameter of gas ejector pipe as far as possible hour, can not cause crooked or other problems because each pressure piece shape is identical and side by side stressed, and be pressed in the wall portion of gas ejector pipe.
According to the useful design of another kind, these pressure pieces produce the loading of point-like and/or wire in wall portion.Therefore employed pressure piece is not a plane earth, but is pressed onto on the gas ejector pipe with being point-like or wire, thereby can produce pressure higher, targetedly or loading.
According to a kind of useful especially design, these pressure pieces form ball, can produce described point-like loading with this, thereby fixing gas ejector pipe optimally, wherein gas ejector pipe generally by Standard Steel promptly for example ST 37 constitute, and simultaneously ball is made with the material that quenches, so can realize the high life-span.
When three balls on being evenly distributed in circumference lead on the inclination start-up portion of mounting block as pressure piece, can realize gas ejector pipe evenly and reliably is fixed in the lance holder especially.At this moment, preferably porose in this inclination start-up portion, corresponding ball is pressed against by these holes on the surface of gas ejector pipe, or rather, is promoted or the pressure slope of the clamping element that moves presses.For this reason, this clamping element has pressure slope adaptive, that stretch equably as mentioned above, thereby guarantees that thus all three balls move on the gas ejector pipe that has inserted in their hole simultaneously, so that reliably gas ejector pipe is kept also so fixedly going down.
When Sealed casing pipe is on abutting in the gas ejector pipe of insertion, toasted adhesion, abandoned making Sealed casing pipe generation linear deformation, promptly abandoned upset (Stauchung).Exactly when the tolerance of gas ejector pipe is big, must consume very big strength and make it distortion.This situation is avoided by solution of the present invention, and according to this solution, mounting block has the wedge shape connection section between the protecting sheathing of the outer wall that can be inserted into Sealed casing pipe and encirclement in a side relative with the inclination start-up portion.This wedge shape connection section affacts on the Sealed casing pipe, and is responsible for making Sealed casing pipe enough closely to abut on the outer wall of gas ejector pipe, and be responsible for to form sealing reliably, or rather, does not preferably take place in the vertical to carry out under the situation of upset.This wedge shape connection section vertically moves for this reason, and as desired the sealing sleeve pipe is pressed onto in the wall portion of gas ejector pipe in this case.If at this moment the wedge shape connection section of mounting block is pulled when unclamping once more, then Sealed casing pipe unloading can recover to be out of shape and to unclamp from remaining gas ejector pipe, thereby Sealed casing pipe can take out from lance holder no problemly.In addition, this method of evenly pressurizeing to gas ejector pipe gives such advantage, can realize that promptly the successive face reclines, and this is can not be guaranteed at the sealing sleeve pipe under by the situation of upset.
The most handy such method of the passing of clamping element on mounting block is carried out, and promptly the clamping element of chuck has gripping sleeve, and gripping sleeve double team clamping element also can move on the outside screw of protecting sheathing.Consume less strength thus and just can realize this clamping element is correspondingly passed on the mounting block, and ball is pressed in the wall portion of gas ejector pipe with this.Just can carry out this process by rotation, wherein by making this rotary course become easier to hacking of handgrip etc. to this gripping sleeve.
Between the clamping wall of a wall of clamping element and gripping sleeve, ball bearing is set, can improves the portability that this passes process thus targetedly.Reduced the friction that in this clamping process, occurs at this ball bearing between gripping sleeve and the clamping element, promptly can carry out this clamping process thereby needn't consume big strength.
This gas ejector pipe must be enough deeply, that is pass Sealed casing pipe and be inserted in the lance holder.In order to accomplish this point reliably, between Sealed casing pipe and fireproof tempering device, be provided with stopping valve, stopping valve has block, and block is used for limiting significantly the property inserted.So, be inserted into the gas ejector pipe that withstands block always and when clamping, allow air-flow freely pass through.Along with gas ejector pipe is pushed in the lance holder, have only when gas ejector pipe enough inserts deeply and can realize accurately sealing with the sealing sleeve pipe, just can start working.Open stopping valve simultaneously.At this moment motionless as long as gas ejector pipe keeps, stopping valve is just opened always, is removed until gas ejector pipe, perhaps must be removed, and at this moment makes valve retract off-position automatically by spring.
For the safety of whole lance holder is further stipulated, remain the vacuum breaker opened by air-flow in the couple positioned opposite of fireproof tempering device.Thereby guarantee that air-flow just can enter in the lance holder with the pressure of needs, and automatic cut-out once more when pressure sharply descends.Guarantee the more accurate and more reliable work of lance holder like this.
For the part that is arranged on after the lance holder itself can be installed separately or keep in repair, the present invention further stipulates, sets the insurance shell that removably is connected with protecting sheathing for the fireproof tempering device that has valve.Two shells are preferably tightened each other.
Point out the front, adopts lance holder of the present invention, can significantly reduce needed scantlings of the structure number.According to the present invention's regulation, for the pipe of metric system, for pipe made in Great Britain, the permission tolerance of mounting block, clamping element and Sealed casing pipe is 3-4mm equally.As mentioned above, can realize always having whole 7 kinds of stent sizes thus and promptly enough use, and the current this stent size that must consider far more than 15 is worked quite reliably so that realize lance holder.Adopt new gas ejector pipe stationary installation can guarantee to work reliably all the time.
Feature of the present invention especially is, a kind of lance holder is provided, it not only can be used for metallurgical industry, also can be used for Iron And Steel Industry, and can be owing to facing unnecessary danger to the possible mal-operation of lance holder or carrying or owing to unallowed gas ejector pipe diameter makes operator.Generally speaking, the gas ejector pipe of insertion optimally is fixed in the lance holder, guarantees simultaneously that wherein gas ejector pipe always enough is inserted in the lance holder deeply in use, that is is inserted into always and withstands till the block.Along with withstanding block or clamping not long ago, the stopping valve that stops gas to flow into is just opened, and flow into and before is fixed in the lance holder and in the sealed gas ejector pipe so gas can pass lance holder.Sealing to necessity of gas ejector pipe no longer realizes by the Sealed casing pipe of linear deformation, or rather, but realizes by following measure that promptly Sealed casing pipe evenly and reliably presses against on the corresponding gas ejector pipe by the wedge shape connection section.So just can adopt the diameter Sealed casing pipe bigger than gas ejector pipe external diameter.Having of chuck can this structure targetedly of pressure piece that move, the ball form be exerted pressure on perpendicular to the direction of longitudinal axes with particularly guaranteeing point-like, optimally gas ejector pipe is fixed on lance holder inside thus, thereby guarantee that gas ejector pipe can not rotate in lance holder, wherein this gas ejector pipe is fixed with chuck and Sealed casing pipe, but fixing more reliable, thereby avoid any obstruction of the fixed of gas ejector pipe with chuck.Even under the situation of gas ejector pipe bending, also can realize reliable maintenance, always because can apply enough power by the point-like of this gas ejector pipe in lance holder or linear fixing.Adopt corresponding sign can make operator determine that corresponding lance holder is given for any pipe diameter to identification visibly and easily.Thereby avoid any danger more reliably.

Fig. 1 is the side-view of lance holder 1.Gas ejector pipe 2 is inserted into the gripping sleeve 25 from the front.Gripping sleeve 25 or chuck 3 are included in unshowned mounting block 4 and clamping element 5 here.Mounting block 4 and clamping element 5 and Sealed casing pipe 6 mating reactions, they are positioned in the chuck 3 that forms protecting sheathing 9 together.Necessary valve is installed in back to back insurance shell 10, also will be thoroughly discussed about this point back.On this insurance shell 10, tighten rotary valve 11, have manufacturer's information 40 on the rotary valve.
Lance holder 1 shown in Fig. 1 is represented with section in Fig. 2.Here as can be seen, this gas ejector pipe 2 passes chuck 3 and in depth is inserted in the lance holder 1.Above-mentioned Sealed casing pipe 6 usefulness wedge shape connection sections 22 are pressed in the wall portion 18 of gas ejector pipe 2, thereby seal completely.What this wedge shape connection section 22 formed mounting blocks 4 is in the end 21 of relative position with inclination start-up portion 14.This wedge shape connection section 22 is pressed between the outer wall 23 and protecting sheathing 9 of Sealed casing pipe 6 when operation chuck 3 or gripping sleeve 25, thereby Sealed casing pipe 6 correspondingly is out of shape and abuts in the wall portion 18.
The opposite side 21 of mounting block 4 is responsible for this distortion or is responsible for making Sealed casing pipe 6 to be pressed in the wall portion 18, and simultaneously the front side has inclination start-up portion 14, this inclination start-up portion be provided with can with the longitudinal axes 15 vertical directions of gas ejector pipe 2 on the pressure piece 16 that moves.These pressure pieces 16 work by the pressure slope 17 of clamping element 5, are pulled to above the inclination start-up portion 14 of relative configurations when gripping sleeve 25 or chuck 3 rotations.These pressure pieces 16 form ball 20, this as can be seen from Figures 2 and 3, wherein these balls 20 directly are pressed in the wall portion 18, thereby guarantee the secure fixation to gas ejector pipe.On entire circumference, distribute be provided with 3 such balls 20,20 ', their shapes are identical and side by side have an effect by pressure slope 17.In order to make these moving processes, that is clamping element 5 carries out as far as possible in the same manner along moving of gripping sleeve 25, is provided with 3 balls of ball bearing 30 between the clamping wall 29 of the wall 28 of clamping element 5 and gripping sleeve 25 or chuck 3.Reduce to minimum with this friction; make the internal thread 26 by outside screw on the protecting sheathing 9 27 and gripping sleeve 25 can apply necessary power, so that guarantee equably and side by side to make pressure slope 17 to move on the pressure piece 16 or on the ball 20 no problemly.
Along with gas ejector pipe 2 is pushed in the lance holder 1, the stopping valve 32 that is arranged between Sealed casing pipe 6 and the fireproof tempering device (R ü ckbrandsicherung) 7 is opened.The outer wall 8 or 23 of Sealed casing pipe 6 is not stressed by wedge shape connection section 22 as yet this moment, thereby gas ejector pipe 2 can correspondingly further insert easily.Along with pushing up block 33, at this moment as mentioned above, stopping valve 32 overcomes spring force and moves, and the distance that is moved makes gas can be incorporated into lance holder 1 now, but also must take fixation in advance.Have only at this moment just can discharge air-flow 34, air-flow is opened the vacuum breaker 36 that is set for fireproof tempering device 7 at opposite side 35.To operate unshowned unlatching and stopping valve in advance here for this reason.
Fig. 3 illustrates the working position of the lance holder 1 of the gas ejector pipe 2 that the diameter minimum is housed, that is vacuum breaker 36 can be opened by air-flow 34 now, so that allow the gas stream mistake.Fig. 3 explanation, as the pressure piece 16 of ball 20 be suitable for to gas ejector pipe 2 apply point-like pressure and with this with its secure fixation.
Fig. 4 illustrates the lance holder 1 that has the gas ejector pipe 2 that is inserted into, and the diameter that is set for such lance holder of gas ejector pipe 2 is big as far as possible, also is 17.5mm.Compare and obviously to find out with Fig. 2, even the special formed assurance of Sealed casing pipe 6 also can seal under the obviously big situation of diameter all the time reliably.Wedge shape connection section 22 is corresponding far to be moved, so that realize this point, wherein makes ball 20 can apply its fixed action, although pressure slope 17 just affacts on these balls a little.In contrast, as can be seen from Figure 2, the securing position of ball 20 in wall portion 18 has only by the corresponding far away mobile of the pressure slope 17 of clamping element 5 and just can reach.
Even on position shown in Figure 4, can open vacuum breaker 36 by opening the gas passage now, so that allow air-flow 34 and enter into gas ejector pipe 2 by lance holder 1.
At last, Fig. 5 provides the section of lance holder 1, and it unclamps, because gas ejector pipe 2 does not insert as yet.
Stopping valve 32 is shifted onto rest position by affiliated spring, is far pushed back and the block 33 that the gas ejector pipe 2 that will be remained to be pushed influences is corresponding here.Gas ejector pipe 2 passes to be introduced passage 37 and is advanced to always and withstands till this block 33, promotes whole assembly then, and stopping valve 32 is opened.
At Fig. 5 as can be seen, ball 20 is bearing in the hole 38, or rather, they can with the longitudinal axes 15 vertical directions of gas ejector pipe 2 on move.Even when introducing the gas ejector pipe that has Fig. 4 or diameter shown in Figure 2, also can fix the gas ejector pipe 2 that inserts exactly by this special construction.For gas ejector pipe with different therewith diameters, must use the lance holder of relative configurations, wherein as previously mentioned, the advantage of lance holder of the present invention particularly is, can handle the pipe tolerance of 3-4mm reliably.
In addition, advantageously, have only when gas ejector pipe 2 to be inserted in the lance holder 1 when withstanding block 33, oxygen or gas just can flow.Lance holder 1 gross weight is light, and structure is very compact.Chuck 3 quenches, thereby the life-span can be very long.In addition advantageously, lance holder 1 mounts and dismounts easily, suits especially in steel mill or metallurgical industry work.
