いる。A dry gas boulder is one type of equipment that stores gases such as coke oven gas and blast furnace gas generated in steelworks caps and uses them as fuel. By balancing the pressure of the gas that generates the upward force with the downward force such as the heavy surroundings of the piston (
The storage pressure is maintained by raising and lowering (a natural physical balance) and preventing dilution from being mixed in with air, etc.

。The general JA construction of such a dry gas holder is, for example, the second
As shown in the figure, a polygonal or circular bottom plate 1 is laid on a foundation such as concrete or the ground, and supports 2 such as T-shaped steel are erected at the apex of the polygon or at pitches around the circumference of the bottom plate 1. Then, side plates 3 are sequentially welded and stacked between these branches 2, and the upper part 17i] is covered with a dome-shaped roof 4 to form a holder body 5. A piston 6 is installed which is moved up and down by the gas.

プリングによって常に側板３に均等に接触しながら昇降
するようにしている。A sealing device 7 is attached to the outer edge of the piston 6 to prevent stored gas from leaking from the gap between the piston 6 and the holder body 5. A guide roller 8 is provided around the piston so that the piston moves up and down while constantly contacting the side plate 3 evenly by means of a spring.
このような乾式ガスボルダでは、ガス足の増減にともな

ラ８を介してホルダ本体５を構成する側板３に応ツノが
加わる。In such a dry gas boulder, when the piston 6 tilts while moving up and down as the amount of gas increases or decreases, a corresponding angle is applied to the side plate 3 forming the holder body 5 via the guide roller 8.

給されているシール油がボルダ本体５の外側に漏れ、周
囲環境の悪化をＪｕいてしまう。Therefore, if the stress applied to the side plate 3 exceeds the limit of the material strength of the side plate 3, the seal oil supplied to the sealing device 7 will leak to the outside of the boulder body 5, causing cracks in the side plate 3 to leak to the outside of the boulder body 5. I feel bad for the situation.
また、亀裂した側板３の修理には、漏れたシール油の清
掃等が必要で非常に煩雑である。Furthermore, repairing the cracked side plate 3 requires cleaning of leaked seal oil, which is very complicated.
このような側板３の亀裂や破損の原因は、側板３にかか

用することによる疲労破壊の場合が非常に多い。The cause of such cracks and breakage of the side plate 3 is not only due to the magnitude of the stress applied to the side plate 3, but also often due to fatigue failure caused by repeated application of even small stress.

〔実施例）
以下、この発明の一実施例を図面に基づき詳細に説明づ
°る。[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.
第１図はこの発明の乾式ガスホルダの側板破壊警報装置
の一実施例の概略構成図である。FIG. 1 is a schematic diagram of an embodiment of a side plate breakage alarm device for a dry gas holder according to the present invention.

になっている。The piston 6, which is installed in the holder body 5 of the dry gas holder and moves up and down as the stored gas melon increases and decreases, is provided with three inclination detectors 10 equally spaced around the circumference for detecting its inclination. A detection signal is input to the device 11.

に応じ３ ｆｌｌｉ１以上Ｌ１四する。As these inclination detectors 10, tape-type position detectors are used, or seal oil supplied to the sealing device of the piston 6 moves as the piston 6 inclines, resulting in a change in head pressure. , use a pressure gauge or differential pressure gauge to measure this pressure, and adjust the pressure by 3 fli1 or more as necessary.

号に基づき傾斜方向と傾斜ａが演算によって求められる
。すなわち、ピストン６の水平面に対する３ケ所の傾斜
を検出して最も傾いている方向（傾斜方向）と傾斜角度
（傾斜口）を求める。In the tilt calculation rI 2111, the tilt direction and the tilt a are calculated based on the detection signal from the tilt detector 10. That is, the inclinations of the piston 6 with respect to the horizontal plane are detected at three locations, and the most inclined direction (inclination direction) and inclination angle (inclination mouth) are determined.
また、ホルダ本体５には、ビス１−ン６の位置、例えば
底板からの高さを検出するだめの位置検出器１２が取付
けである。Further, a position detector 12 is attached to the holder body 5 to detect the position of the screw 1-6, for example, the height from the bottom plate.

標位置を読み込む。この座標としては例えば、側板３を
長方形状に展開したとして、これを多数に分割した直交
座標の点を用いる。Then, the position number 43 from the position detector 12 is input to the side plate position setting device 13, and a predetermined coordinate position on the side plate 3 of the dry gas holder is read based on the tilt direction data from the tilt effect 511. As these coordinates, for example, assuming that the side plate 3 is developed into a rectangular shape, points of orthogonal coordinates obtained by dividing this into a large number of parts are used.

逆に傾斜方面下側では、上下一対のガイドローラのうち
上側のもので、それぞれ側板３に応力が発生することに

演ｐで求められる。On the other hand, the maximum inclination angle (inclination m) calculated in the inclination calculation 2S11 is input to the stress generator 14, and the stress on the side plate 3, which is the reaction force of the force pressing the side plate 3 by the piston 6, is calculated from the inclination m. . That is, when the piston 6 inclines, the side plate 3 is pushed by the guide roller, and on the upper side in the inclination direction, the lower one of the pair of upper and lower guide rollers,
On the other hand, on the lower side of the slope, the upper one of the pair of upper and lower guide rollers generates stress on the side plate 3, and the value of the stress is determined by the calculation p from the force balance as a function of the slope angle.
こうしてピストン６によってガイドローラを介して側板

板３の座標が記憶器１５に入力され、応力の回数ととも
にＩｔｉｌされる。When the stress generated on the side plate 3 by the piston 6 via the guide roller is thus determined, its magnitude and the coordinates of the side plate 3 are input into the memory 15 and stored together with the number of times of stress.
このような応力の記憶がピストン６の昇降にともなって
生ずる傾斜のたびに行なわれ、側板３のどの位置にどの
くらいの大きさの応力が何口加わったかによって側板３
の疲労度合が求められる。Memorization of such stress is carried out every time the piston 6 is tilted as it moves up and down, and the side plate 3 is stored depending on which position of the side plate 3 and how many pieces of stress are applied.
The degree of fatigue is required.
そして、記憶されたデータと記憶器１５に予め設定した
側板３の材料の疲労破壊が生ずる応力の大きさおよび回
数等の材料固有の疲労限界と比較され、疲労限界の直前
になるとυ報ｚ１６に信号を送り、警報を出す。Then, the stored data is compared with the material-specific fatigue limit, such as the magnitude and number of times of stress that will cause fatigue failure of the material of the side plate 3, which has been set in advance in the memory 15, and when the fatigue limit is reached, the υ signal z16 is sent. Send signals and issue alarms.
この警報２Ｓ１６からのｖ１報は、ピストン６による側
板３の応力が１回であっても非常に大きければ短期間に
発せられるが、通常、繰り返しによる疲労破壊の場合に
は、運転開始後、５〜１０年程度の長期間の後に発せら
れることが多い。This v1 alarm from alarm 2S16 is issued in a short period of time if the stress on the side plate 3 caused by the piston 6 is extremely large even if it occurs once, but normally, in the case of repeated fatigue failure, the It often occurs after a long period of about 10 years.
こうして１２９！１が発せられたのち、乾式ガスホルダ
の運転を停止し、疲労破壊直前の側板３の交換等の修理
を行ない、シール油の漏洩やこのための周囲環境悪化を
防止する。After 129!1 is issued in this way, the operation of the dry gas holder is stopped and repairs such as replacing the side plate 3 that is about to break due to fatigue are carried out to prevent leakage of seal oil and the deterioration of the surrounding environment due to this.

It is sufficient that the inclination and position of the piston can be detected, and any type of method such as one that detects electrically or one that uses physical ports such as pressure may be used.

Since a warning is issued immediately before fatigue failure occurs by comparing the piston with the piston, the seal oil of the seal device provided around the piston is prevented from leaking to the outside, and contamination due to the seal oil can be prevented.
