Description

本発明は、溶融金属の各種特性を測定するためのサブランスプローブを、サブランス下端のホルダーへ装着する方法に係わり、特に、地金付き防止用の稼動型スリーブを備えるサブランスプローブの装着方法、及びサブランスプローブに関する。   The present invention relates to a method of mounting a sublance probe for measuring various characteristics of molten metal to a holder at the lower end of the sublance, and in particular, a mounting method of a sublance probe provided with an active sleeve for preventing bullion. And a lance probe.

この種のサブランスプローブは、従来、浸漬時に溶湯のスプラッシュ等により該サブランスに地金が付き、浸漬後に新しいサブランスプローブを装着する際に不完全装着により導通不良を誘発する。付着した地金は人的作業で改修する必要があり、手間がかかり且つ安全上問題である。そこで、この地金付きを防止するために、地金付着防止用スリーブを該プローブに設けることが行われている。このスリーブの構造としては、プローブ筒体の後端位置にステープル釘でスリーブが強固に固定される固定型と、スリーブがプローブ筒体の外面にスライド可能に外被される稼動型に大別される。   Conventionally, this type of sublance probe has a metal base attached to the sublance due to a splash of molten metal during immersion, and induces poor conduction due to incomplete attachment when a new sublance probe is attached after immersion. The attached bullion needs to be repaired manually, which is troublesome and a safety issue. Therefore, in order to prevent the metal sticking, a metal sticking prevention sleeve is provided on the probe. The structure of this sleeve is roughly divided into a fixed type in which the sleeve is firmly fixed with a staple nail at the rear end position of the probe cylinder and an operating type in which the sleeve is slidably covered on the outer surface of the probe cylinder. The

一般的にサブランスプローブは溶湯に浸漬部分が最も溶損するため、プローブ折損や採取サンプルの落下等を防止するべく溶湯に浸漬するプローブ筒体先端部分の外径を太く設定しているが、固定型の場合は、溶湯に浸漬されずに溶損の少ない先端部よりも後ろ側の部分を細くし、その後端にスリーブを固定することができ、スリーブによる全体外径の増加を避けられるものの、スリーブを含む使用前のプローブ全長が長いため、自動装着装置の大型化、輸送や保管等の取り回しの悪さなどの面でデメリットがある。   In general, the sublance probe has the largest outer diameter at the tip of the probe cylinder that is immersed in the molten metal to prevent breakage of the probe and the fall of the collected sample, etc. In the case of the mold, it is possible to narrow the back side of the tip part with little loss of melting without being immersed in the molten metal, and to fix the sleeve to the rear end, while avoiding an increase in the overall outer diameter due to the sleeve, Since the entire length of the probe including the sleeve before use is long, there are disadvantages in terms of increasing the size of the automatic mounting device and poor handling in transportation and storage.

稼動型のものは、プローブ筒体の浸漬される先端側部分から後端部にわたりスリーブがスライド可能に外被され、装着クランプで該プローブ筒体の外面に沿って軸方向にスライド移動させる構造であり（例えば、特許文献１〜３参照。）、使用前にはステープル釘で仮固定されており、装着クランプで掴んで可動させるとステープル釘が容易に外れ、スリーブがスライドできるように構成されている。この稼動型のものは、使用前のプローブ全長を短くできるが、スリーブをクランプで掴みサブランスプローブ全体を上方に移動させ、ホルダーに装着する際、クランプで掴んでいるスリーブが容易にスライドして（逃げて）しまい、プローブ筒体の装着が確実にできなくなる場合がある。すなわち、プローブ筒体をサブランスに装着するためには最低でも５０ｋｇｈ程度の装着力が必要となるが、スリーブをクランプで掴んで当該５０ｋｇｈの力をかけようとしてもプローブ筒体が装着する前にスリーブが上方に稼動してしまい、当該力をプローブ筒体にかけることができず、その結果コネクタ接続が不十分になるなど、確実な装着ができないこととなる。   The operating type has a structure in which the sleeve is slidably covered from the tip side where the probe cylinder is immersed to the rear end, and is slid in the axial direction along the outer surface of the probe cylinder by the mounting clamp. Yes (see, for example, Patent Documents 1 to 3), it is temporarily fixed with a staple nail before use, and is configured so that the staple nail can be easily detached and the sleeve can be slid when grasped by a mounting clamp and moved. Yes. This operating type can shorten the total length of the probe before use, but when the sleeve is grasped with the clamp and the entire sublance probe is moved upward and attached to the holder, the sleeve grasped with the clamp slides easily. In some cases, the probe cylinder may not be securely attached. That is, in order to mount the probe cylinder to the sub lance, a mounting force of at least about 50 kgh is required. However, even if the sleeve is clamped and the force of 50 kgh is applied, the sleeve before the probe cylinder is mounted Will not be able to apply the force to the probe cylinder, and as a result, the connector will be insufficiently connected.

そこで、ホルダーへの装着の際スリーブが容易にスライドしないように、稼動型スリーブとプローブ筒体との間のクリアランスを小さくし、抵抗を増やすことも行われている。しかしながら、プローブ筒体は通常１．５〜２ｍの長さを有する紙管からなり、多少なりとも曲がりや反りが発生するため摩擦抵抗が大きくなりすぎ、クランプしている紙管表面がすべって逆に稼動スリーブが装着できないという稼動不良の問題が発生する。クリアランスを調節してこの摩擦抵抗を上手く設定することは難しく、また、スリーブ表面湿度や温度でスリーブにも反りや曲がりが発生しやすく、またプローブ筒体やスリーブの反りや曲がりだけでなくホルダー側の使用による曲がりやサブランスを含む装置のガタなどにより摩擦抵抗は容易に変化し、抵抗が過大にならないようにクリアランスを調節することは実際上、非常に困難であった。   Therefore, in order to prevent the sleeve from sliding easily when mounted on the holder, the clearance between the active sleeve and the probe cylinder is reduced to increase the resistance. However, the probe cylinder is usually made of a paper tube having a length of 1.5 to 2 m. Since the bending or warping occurs to some extent, the frictional resistance becomes too large, and the surface of the clamped paper tube slips and reverses. This causes the problem of operation failure that the operation sleeve cannot be installed. It is difficult to set this friction resistance well by adjusting the clearance, and the sleeve tends to warp and bend due to the sleeve surface humidity and temperature, and the holder side as well as the probe cylinder and sleeve warp and bend The frictional resistance easily changes due to bending due to the use of the device and backlash of the device including the sub lance, and it is actually very difficult to adjust the clearance so that the resistance does not become excessive.

このようなクリアランスを小さくすることによる稼動不良の問題を避けるためには、クリアランスを小さくすることなく、上記スリーブの逃げを防止する必要があるた、そのためには筒状プローブ装着用のクランプとスリーブ稼動用のクランプの二つが必要となり、装置の大型化、複雑化、コストアップを招くという問題があった。更に、従来の稼動型のスリーブは、溶損防止のため比較的大径に構成される筒状プローブ先端部分に重ねるように被着されているため、固定型に比べプローブ全体の外径が太くなってしまい、装着クランプ等も大型なものが必要となり費用がかかる問題もあった。   In order to avoid the problem of operation failure due to such a small clearance, it is necessary to prevent the sleeve from escaping without reducing the clearance. To that end, a clamp and a sleeve for mounting the cylindrical probe are required. Two clamps for operation are required, and there is a problem that the apparatus becomes large, complicated, and costs increase. Furthermore, since the conventional operating type sleeve is attached so as to overlap the tip portion of the cylindrical probe having a relatively large diameter in order to prevent melting damage, the outer diameter of the entire probe is larger than that of the fixed type. As a result, there is a problem that the mounting clamp is required to be large and expensive.

そこで、本発明が前述の状況に鑑み、解決しようとするところは、地金付着防止用スリーブがプローブ外面にスライド可能に外被される稼動型において、プローブ筒体を上方に移動させてホルダーに装着する際、クランプで掴んでいるスリーブが逃げずに確実に装着できるとともに、二つのクランプを用いる複雑な構造を採用することなく、装置の大型化や複雑化、コスト増大等を回避でき、また、稼動型スリーブとプローブ筒体との間のクリアランスを小さくする必要もなく稼動不良も未然に回避できるプローブ装着方法および該プローブ装着方法が可能なサブランスプローブを提供する点にある。   Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that in the operation type in which the metal adhesion preventing sleeve is slidably covered on the outer surface of the probe, the probe cylinder is moved upward to the holder. When mounting, the sleeve grasped by the clamp can be securely mounted without escaping, and without adopting a complicated structure using two clamps, it is possible to avoid an increase in size, complexity, cost increase, etc. Another object of the present invention is to provide a probe mounting method capable of avoiding operation failure without reducing the clearance between the operating sleeve and the probe cylinder, and a sublance probe capable of performing the probe mounting method.

本発明は、前述の課題解決のために、炉内へ昇降自在に配置したサブランスの下端に設けたホルダーに装着して使用され、溶融金属の温度測定、凝固温度測定、酸素測定、および溶融金属採取のうち少なくとも１つ以上の機能を有するプローブ筒体に、地金付き防止用の稼動型スリーブを設けてなるプローブの前記ホルダーへの装着方法であって、前記プローブ筒体における前記稼動型スリーブのプローブ先端側に隣接する位置に筒状部を設け、プローブ装着の際、前記筒状部と稼動型スリーブの双方を跨ぐように同一クランプで掴み、当該プローブをサブランス方向に相対移動させることにより、該プローブに前記ホルダーが装着され、さらにクランプをサブランス方向に移動させて該クランプとともに稼動型スリーブのみをスライド稼動させ、地金付き防止位置に装着することを特徴とするプローブ装着方法を提供する。   In order to solve the above-mentioned problems, the present invention is used by being mounted on a holder provided at the lower end of a sub lance arranged to be movable up and down in the furnace, and is used for temperature measurement of molten metal, solidification temperature measurement, oxygen measurement, and molten metal. A method of mounting a probe to the holder, wherein a probe cylinder having at least one function of sampling is provided with an operation sleeve for preventing a bare metal from being attached to the holder, the operation sleeve in the probe cylinder By providing a cylindrical part at a position adjacent to the probe tip side, and holding the probe with the same clamp so as to straddle both the cylindrical part and the operating sleeve, and relatively moving the probe in the sub lance direction The holder is attached to the probe, and the clamp is further moved in the sub lance direction so that only the movable sleeve is slid along with the clamp. So, to provide a probe mounting method characterized by mounting the bare metal with preventing position.

ここで、前記筒状部を、前記稼動型スリーブとほぼ同じ外径寸法に設定することが好ましい。   Here, it is preferable that the cylindrical portion is set to have substantially the same outer diameter as the working sleeve.

また、本発明は炉内へ昇降自在に配置したサブランスの下端に設けたホルダーに装着して使用され、溶融金属の温度測定、凝固温度測定、酸素測定、および溶融金属採取のうち少なくとも１つ以上の機能を有するプローブ筒体に、地金付き防止用の稼動型スリーブを設けてなり、前記プローブ筒体における前記稼動型スリーブのプローブ先端側に隣接する位置に、該稼動型スリーブとほぼ同じ外径寸法を有する筒状部を設けたことを特徴とするサブランスプローブであって、上記プローブ装着方法が可能なサブランスプローブをも提供する。   In addition, the present invention is used by being attached to a holder provided at the lower end of a sub lance arranged to be movable up and down in the furnace, and at least one of molten metal temperature measurement, solidification temperature measurement, oxygen measurement, and molten metal sampling. The probe cylinder having the above function is provided with an active sleeve for preventing a bare metal from being attached, and the probe cylinder is located at a position adjacent to the probe tip side of the active sleeve and is substantially the same as the active sleeve. There is also provided a sublance probe characterized in that a cylindrical portion having a radial dimension is provided, and the above-described probe mounting method is possible.

ここで、前記稼動型スリーブを、プローブ筒体の基端側にスライド可能に設けるとともに、前記筒状部を、前記稼動型スリーブのプローブ先端側に隣接する位置に、前記プローブ筒体と一体的に設けたものが好ましい。   Here, the operating sleeve is slidably provided on the proximal end side of the probe cylinder, and the cylindrical portion is integrated with the probe cylinder at a position adjacent to the probe distal end side of the operating sleeve. What was provided in is preferable.

以上にしてなる本願発明によれば、一つのクランプでプローブ筒体の筒状部と稼動型スリーブの双方を掴んでいるので、ホルダーに装着する際には、クランプで筒状部を掴んでいることからスリーブが逃げることなく確実にプローブ筒体をコネクタ接続して装着することができ、そのまま更にクランプをサブランス方向に移動させれば、装着完了したプローブ筒体上を稼動型スリーブがクランプとともに移動し、地金付き防止位置にスムーズに装着でき、二つのクランプを用いることなく、プローブ筒体の装着とスリーブ稼動を行うことができ、装置の大型化や複雑化、コスト増大等を回避できるとともに、上述のとおりスリーブの逃げを防止できるため稼動型スリーブとプローブ筒体とのクリアランスを十分にとってもホルダーへの装着を確実にでき、その後の稼動型スリーブの移動もスムーズにでき、スリーブの稼動不良を未然に回避できる。   According to the present invention as described above, since both the cylindrical portion of the probe cylinder and the working sleeve are gripped by one clamp, when mounting on the holder, the cylindrical portion is gripped by the clamp. Therefore, the probe cylinder can be securely connected and attached without escaping the sleeve. If the clamp is moved further in the sub lance direction, the active sleeve moves with the clamp on the completed probe cylinder. In addition, it can be mounted smoothly at the position where it is prevented from being attached to the bullion, and it is possible to mount the probe cylinder and operate the sleeve without using two clamps, avoiding the increase in size, complexity and cost of the device. As mentioned above, it is possible to prevent the sleeve from escaping, so that the clearance between the active sleeve and the probe cylinder can be secured to the holder. Indeed can, then the can also be moved to the smooth operation type sleeve, it is possible to avoid the operation failure of the sleeve in advance.

また、筒状部を稼動型スリーブとほぼ同じ外径寸法に設定したので、外径が異なる場合に段差が必要となるクランプに比べ、従来のクランプをそのまま使用して双方を掴むことも可能となりコスト増大を防止できるとともに、クランプで双方を掴む際に多少の上下のズレがあっても許容でき、設備設計上の自由度も維持される。   In addition, since the cylindrical part is set to the same outer diameter as the working sleeve, it is possible to grip both using the conventional clamp as it is, compared to a clamp that requires a step when the outer diameter is different. In addition to preventing an increase in cost, it is permissible even when there is a slight vertical shift when gripping both sides with a clamp, and the degree of freedom in equipment design is maintained.

また、稼動型スリーブをプローブ筒体の基端側にスライド可能に設けるとともに、前記筒状部を前記稼動型スリーブのプローブ先端側に隣接する位置に前記プローブ筒体と一体的に設けたので、従来の稼動型のスリーブのように筒状部の外側に重ねるように被着して全体の外径が太くなってしまうといった問題が回避でき、固定型と同様の外径に抑えることが可能となる。   In addition, the operating sleeve is provided slidably on the proximal end side of the probe cylinder, and the cylindrical portion is provided integrally with the probe cylinder at a position adjacent to the probe distal end side of the operation sleeve. It is possible to avoid the problem that the entire outer diameter becomes thicker by attaching it to the outside of the cylindrical part like a conventional operating type sleeve, and it can be suppressed to the same outer diameter as the fixed type Become.

次に、本発明の実施形態を添付図面に基づき詳細に説明する。   Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

本発明のサブランスプローブ１は、炉内へ昇降自在に配置したサブランスの下端に設けたホルダーに装着して使用され、図１に示すように、溶融金属の温度測定、凝固温度測定、酸素測定、および溶融金属採取のうち少なくとも１つ以上の機能を有するプローブ筒体１０に、地金付き防止用の稼動型スリーブ２を設け、プローブ筒体１０における稼動型スリーブ先端側２ａに隣接する位置に、該稼動型スリーブ２とほぼ同じ外径寸法を有する筒状部３を設けたことを特徴とする。   The sublance probe 1 of the present invention is used by being mounted on a holder provided at the lower end of a sublance that is arranged to be movable up and down into the furnace. As shown in FIG. 1, the temperature measurement of the molten metal, the solidification temperature measurement, and the oxygen measurement are performed. , And the probe cylinder 10 having at least one of the functions of collecting molten metal is provided with an active sleeve 2 for preventing metal from being attached to the probe cylinder 10 at a position adjacent to the distal end 2a of the active sleeve. The cylindrical portion 3 having substantially the same outer diameter as that of the working sleeve 2 is provided.

プローブ筒体１０は、紙製の筒状本体１１の内部に測温センサ７０や溶融金属採取室７３、カーボンセンサ７１、コネクタ７２等を内装して構成されており、筒状本体１１は、長手方向に延びる外管６０と内管６１、６２より構成され、内管６２の先端部には測温センサ７０が設けられる紙製の支持筒６３が支持され、同じく内管６２の中央位置には採取容器７４やその取込部７５が内挿支持され、基端部にはコネクタ７２が設けられている。   The probe cylinder 10 is configured such that a temperature sensor 70, a molten metal collection chamber 73, a carbon sensor 71, a connector 72, and the like are housed inside a paper cylinder main body 11, and the cylinder main body 11 has a longitudinal shape. The outer tube 60 and inner tubes 61, 62 extending in the direction are configured. A paper support cylinder 63 provided with a temperature sensor 70 is supported at the tip of the inner tube 62. The collection container 74 and its take-in part 75 are inserted and supported, and a connector 72 is provided at the base end part.

測温センサ７０は、支持筒６３の先端開口部に突出状態で装着したものであり、鉄カバーで覆われた内部に、アーチ状の石英保護管付き熱電対７７を配設したものであり、その頂点付近に熱電対の測温接点を有した測温部を備えている。また鉄カバーはさらに紙キャップで覆われている。熱電対によって測定される測温値は、溶融金属の温度変化をリアルタイムに測温する為の手段として利用される。尚、このような測温センサ７０を設けること以外に、酸素センサなど種々のセンサを代わりに或いは併設してもよい。また、測温センサ７０にサンプラーを併設することも可能である。   The temperature measuring sensor 70 is mounted in a protruding state at the tip opening of the support cylinder 63, and an arch-shaped thermocouple 77 with a quartz protective tube is arranged inside covered with an iron cover. A temperature measuring unit having a temperature measuring contact of a thermocouple is provided near the apex. The iron cover is further covered with a paper cap. The temperature measurement value measured by the thermocouple is used as a means for measuring the temperature change of the molten metal in real time. In addition to providing such a temperature sensor 70, various sensors such as an oxygen sensor may be used instead or in combination. In addition, a sampler can be provided along with the temperature sensor 70.

また本例では、筒状本体１１の内部、具体的には内管６２の内面側に溶融金属採取室７３を構成する採取容器７４が内装されており、採取容器７４の開口位置には、筒状本体１１に開設された流入口７６を介して外部に連通される溶融金属取込部７５が設けられ、熱電対よりなるカーボンセンサ７１が設けられている。そして、流入口７６から流入した溶融金属は、キル材で脱酸された後、溶融金属採取室７３内に流入し、カーボンセンサ７１により凝固温度が測定されるとともに凝固したサンプルが元素分析されることとなる。   Further, in this example, a collection container 74 constituting a molten metal collection chamber 73 is provided inside the cylindrical main body 11, specifically, on the inner surface side of the inner tube 62. The molten metal taking-in part 75 connected to the exterior through the inflow port 76 established in the shape main body 11 is provided, and the carbon sensor 71 which consists of a thermocouple is provided. The molten metal flowing in from the inlet 76 is deoxidized with a kill material, and then flows into the molten metal collection chamber 73. The solidification temperature is measured by the carbon sensor 71 and the solidified sample is subjected to elemental analysis. It will be.

また、内管６２の基端側には中軸管６４が内嵌接合されており、この中軸管６４は測温センサ７０やカーボンセンサ７１から導出されるリード線を接続したコネクタ７２が内部に設けられており、ホルダー５０側の電気接点と接続して各センサからの信号を外部に伝送するように構成されている。   Further, an inner shaft pipe 64 is fitted and joined to the proximal end side of the inner tube 62, and the inner shaft pipe 64 is provided with a connector 72 to which a lead wire led out from the temperature sensor 70 and the carbon sensor 71 is connected. It is configured to be connected to an electrical contact on the holder 50 side and transmit a signal from each sensor to the outside.

尚、本発明に係るサブランスプローブは、上記の測定機能を備えたものに何ら限定されず、測温センサーとピンサンプラーとが突設され、連続鋳造設備タンディッシュ用測温サンプラとして用いられる複合プローブとして構成したものや、ピンサンプラーのみ設けもの、測温センサーと酸素センサーを並設したもの、測温センサーとピンサンプラーと酸素センサーをそれぞれ並設したものなど、その他の種々の形態、使用環境用のプローブとして構成することができることは勿論である。   Note that the sublance probe according to the present invention is not limited to the one having the above-described measurement function, and is a composite in which a temperature measuring sensor and a pin sampler are projected and used as a temperature measuring sampler for continuous casting equipment tundish. Various other forms and usage environments, such as a probe, a pin sampler only, a temperature sensor and an oxygen sensor arranged side by side, a temperature sensor, a pin sampler, and an oxygen sensor arranged side by side Of course, it can be configured as a probe.

稼動型スリーブ２は、プローブ筒体１０の基端側１０ｂに、該プローブ筒体１０を構成している筒状本体１１の外管６０外面上に摺動可能に外装されており、上下方向にスライド可能に設けられている。   The operating sleeve 2 is slidably mounted on the outer surface of the outer tube 60 of the cylindrical main body 11 constituting the probe cylinder 10 on the proximal end side 10b of the probe cylinder 10, and is vertically movable. It is slidably provided.

また、稼動型スリーブ２の先端側２ａに隣接する位置には、プローブ筒体１０と一体的に筒状部３が設けられており、該筒状部３は、図３（ａ）にも示すように、稼動型スリーブ２とほぼ同じ外径寸法に設定されている。この筒状部３は、具体的には筒状本体１１を構成している外管６０の外面に密着状態で固定される筒状部材よりなり、プローブ筒体１０の先端側１０ａのうち、溶融金属採取室７３やカーボンセンサ７１が設けられる位置よりも基端側に設けられている。そして該筒状部３よりも先端側には、薄い紙製の筒体６５が更に設けられている。   Further, a cylindrical portion 3 is provided integrally with the probe cylinder 10 at a position adjacent to the distal end side 2a of the operating sleeve 2, and the cylindrical portion 3 is also shown in FIG. 3 (a). Thus, the outer diameter dimension is set to be substantially the same as that of the working sleeve 2. Specifically, the cylindrical portion 3 is formed of a cylindrical member that is fixed in close contact with the outer surface of the outer tube 60 constituting the cylindrical main body 11, and is melted in the distal end side 10 a of the probe cylindrical body 10. It is provided on the base end side from the position where the metal collection chamber 73 and the carbon sensor 71 are provided. A thin paper cylinder 65 is further provided on the tip side of the cylindrical portion 3.

尚、筒状部３とスリーブ２の外径寸法は、上記のように一致させることで従来のクランプを利用できるようにしたものであるが、本発明はこれに限定されず、例えば図３（ｂ）、（ｃ）に示すように外径寸法が異なり、段差部８を有するものでもよい。このような段差部８を有する筒状部３とスリーブ２の双方を掴むためにはクランプにも対応する段差部を設けておく必要があるが、特に図３（ｂ）のようにスリーブ２の外径を筒状部３の外径よりも大きく設定したものでは、コネクタ接続してホルダーに装着した後に更にスリーブを稼動させる際、段差部８の存在によりスリーブ先端側２ａがクランプ４の段差に圧される形になり、プローブの変形等でクリアランスが小さくなっていたとしてもスリーブ２を確実に上方にスライド稼動させることが可能となる点でより好ましい例である。
また、図示したものでは筒状部３とスリーブ２が隙間なく密着しているが、このような形態に何ら限定されず、隣接する位置であれば、クランプ４で双方を掴んで装着できる程度の隙間があっても勿論よい。 The outer diameter of the cylindrical portion 3 and the sleeve 2 are matched as described above so that a conventional clamp can be used. However, the present invention is not limited to this, and for example, FIG. As shown in b) and (c), the outer diameter may be different and the step portion 8 may be provided. In order to grip both the cylindrical portion 3 having the stepped portion 8 and the sleeve 2, it is necessary to provide a stepped portion corresponding to the clamp. In particular, as shown in FIG. In the case where the outer diameter is set larger than the outer diameter of the cylindrical portion 3, when the sleeve is further operated after being connected to the connector and attached to the holder, the sleeve tip side 2 a becomes a step of the clamp 4 due to the presence of the step portion 8. This is a more preferable example in that the sleeve 2 can be reliably slid upward even if the clearance is reduced due to deformation of the probe or the like.
Further, in the illustrated example, the cylindrical portion 3 and the sleeve 2 are in close contact with each other with no gap, but the present invention is not limited to such a form. Of course, there may be a gap.

次に、図２に基づき、上記サブランスプローブ１のホルダーへの装着方法を説明する。   Next, a method for mounting the sublance probe 1 on the holder will be described with reference to FIG.

まず、図中（ａ）〜（ｂ）に示すように、筒状部３と稼動型スリーブ２の双方を跨ぐように同一クランプ４で掴んで、当該プローブ１を移動させることができ、装着時には、上方に移動させ、サブランス５のホルダー５０をスリーブ筒体基端側１０ｂの開口部に挿入してゆく。   First, as shown in (a) to (b) in the figure, the probe 1 can be moved by gripping it with the same clamp 4 so as to straddle both the cylindrical portion 3 and the working sleeve 2. Then, the holder 50 of the sub lance 5 is inserted into the opening of the sleeve cylindrical base end side 10b.

そして、図中（ｃ）に示すようにコネクタ７２がホルダー５０側に電気接続されることで、プローブ筒体１０とホルダー５０の装着が完了する。この際、クランプ４は筒状部３とスリーブ２の双方を掴んでおり、スリーブ２のみが上方に逃げてしまうことなく、筒状部３を確実に上方に移動させ、上記コネクタ７２接続を経てホルダー５０への装着を確実に行うことができるのである。   Then, the connector 72 is electrically connected to the holder 50 side as shown in (c) in the drawing, whereby the mounting of the probe cylinder 10 and the holder 50 is completed. At this time, the clamp 4 holds both the cylindrical portion 3 and the sleeve 2, and the cylindrical portion 3 is reliably moved upward without causing only the sleeve 2 to escape upward. The attachment to the holder 50 can be performed reliably.

尚、本例では、上記のとおり筒状部３とスリーブ２をほぼ同じ外径寸法に設定し、従来と同様のクランプを利用しているが、スリーブ２の逃げをより確実に防止するべく、クランプ４内面と筒状部３外面との摩擦力がクランプ４内面とスリーブ２外面との摩擦力よりも大きくなるように、クランプはそのまま利用し、筒状部３の外径寸法を微小量だけスリーブ２よりも大きく設定したり、クランプ４内面のうち筒状部３を掴む下側部分に摩擦力を高める表面加工を施したり、或いは筒状部３のクランプ４で掴まれる外面側に同じく摩擦力を高める表面加工を施すことなども好ましい例である。   In this example, as described above, the cylindrical portion 3 and the sleeve 2 are set to have substantially the same outer diameter, and a clamp similar to the conventional one is used, but in order to prevent the escape of the sleeve 2 more reliably, The clamp is used as it is so that the frictional force between the inner surface of the clamp 4 and the outer surface of the cylindrical part 3 is larger than the frictional force between the inner surface of the clamp 4 and the outer surface of the sleeve 2, and the outer diameter dimension of the cylindrical part 3 is set to a minute amount. Set to be larger than the sleeve 2, or apply surface treatment to increase the frictional force to the lower part of the inner surface of the clamp 4 that grips the cylindrical part 3, or apply friction to the outer surface of the cylindrical part 3 that is gripped by the clamp 4. It is also a preferable example to perform surface processing for increasing the force.

次に、上記コネクタ接続後、そのままクランプ４を上昇させると、プローブ筒体に一体化されている筒状部３がこれ以上移動しないことから、該筒状部３とクランプ４との間はスリップを起こし、図中（ｄ）に示すようにスリーブ２のみがクランプ４に掴まれたまま上方に移動してスライド稼動し、図中（ｅ）に示すように地金付き防止位置に装着される。図中（ｆ）は、クランプを外したプローブ装着完了状態を示している。尚、プローブ１をサブランス５から離脱させる際には、上記と逆の工程を辿れることができる。   Next, when the clamp 4 is lifted as it is after the connector is connected, the cylindrical portion 3 integrated with the probe cylindrical body does not move any further, so that there is a slip between the cylindrical portion 3 and the clamp 4. As shown in (d) in the figure, only the sleeve 2 is moved upward while being gripped by the clamp 4, and is slid to be mounted, as shown in (e) in the figure. . In the figure, (f) shows the probe mounting completed state with the clamp removed. It should be noted that when detaching the probe 1 from the sublance 5, the reverse process can be followed.

以上、本発明の実施形態について説明したが、本発明はこうした実施例に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲において種々なる形態で実施し得ることは勿論である。特に、本発明のサブランスプローブは一つのクランプで筒状部とスリーブの双方を掴んで装着する方法に使用可能なプローブであるが、その他の方法、例えば筒状部等を掴むプローブ装着クランプとスリーブを掴むスリーブ稼動用クランプの２つのクランプを用いた設備で使用すること等も勿論できる。   Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can of course be implemented in various forms without departing from the gist of the present invention. In particular, the sublance probe of the present invention is a probe that can be used for a method of gripping and mounting both the cylindrical portion and the sleeve with a single clamp, but other methods, for example, a probe mounting clamp for gripping the cylindrical portion, etc. Of course, it is possible to use in a facility using two clamps of the sleeve operation clamp for gripping the sleeve.
