Description

この発明は、レールと車輪との間に噴射物を噴射する噴射装置が動作していないときに、この噴射装置から漏出するこの噴射物の漏出量を低減する噴射物の漏出低減装置に関する。   BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a device for reducing the leakage of a propellant which reduces the amount of leakage of the propellant which leaks from the injector when the injector for injecting the propellant between the rail and the wheel is not operating.

鉄道車両では、セラミックス又は珪砂などの増粘着材をレールと車輪との間に毎分10〜50g程度高速で噴射する噴射装置を台車に取り付けて、高速車両の空転又は滑走を防止するとともに、ブレーキ距離を確保し機関車の砂まき量の低減を図っている。従来の噴射装置は、鉄道車両のレールと車輪との間に増粘着材を噴射する噴射ノズルと、この増粘着材を充填して加圧する圧力タンクと、圧力タンクに圧縮空気を供給する空気タンクと、圧力タンクに圧縮空気が供給されたときに圧力タンクから噴射ノズルに圧縮空気とともに増粘着材を供給する供給配管を備えている（例えば、特許文献１参照）。このような従来の噴射装置では、圧力タンク内に圧縮空気が供給されたときに、圧力タンク内の供給配管の吸込口から増粘着材を吸い込み、増粘着材を圧縮空気とともに噴射口から噴射している。   In a rail car, an injection device that injects an adhesive material such as ceramics or silica sand at a high speed of about 10 to 50 g per minute between a rail and a wheel is attached to a bogie to prevent idling or gliding of a high speed vehicle The distance is secured to reduce the amount of sanding of the locomotive. A conventional injection device comprises an injection nozzle for injecting an adhesive material between rails and wheels of a railway vehicle, a pressure tank for filling and pressurizing the adhesive material, and an air tank for supplying compressed air to the pressure tank. And, when compressed air is supplied to the pressure tank, there is provided a supply pipe for supplying the pressure-sensitive adhesive together with the compressed air from the pressure tank to the injection nozzle (see, for example, Patent Document 1). In such a conventional injection device, when compressed air is supplied into the pressure tank, the adhesive is sucked from the suction port of the supply pipe in the pressure tank, and the adhesive is injected from the injection port together with the compressed air. ing.

従来の噴射装置では、鉄道車両が線路上を走行するとこの鉄道車両の台車とともに振動する。このため、従来の噴射装置では、空気タンクから圧力タンクに圧縮空気が供給されていない非噴射時であるにもかかわらず、鉄道車両が特定の加速度及び周波数で振動したときには、圧力タンク内の増粘着材が供給配管の吸込口から供給配管に自然漏出する現象が起きることがある。その結果、従来の噴射装置では、圧力タンクから増粘着材が自然漏出して、圧力タンク内の増粘着材が無駄に消費されてしまう問題点がある。   In a conventional injection device, when a railway vehicle travels on a track, it vibrates with the bogie of the railway vehicle. For this reason, the conventional injection device increases the pressure in the pressure tank when the railway vehicle vibrates at a specific acceleration and frequency even though the compressed air is not supplied from the air tank to the pressure tank during non-injection. The phenomenon in which the adhesive material leaks spontaneously to the supply pipe from the suction port of the supply pipe may occur. As a result, in the conventional injection device, the pressure-sensitive adhesive material naturally leaks from the pressure tank, and the pressure-sensitive adhesive material in the pressure tank is wastefully consumed.

次に、この発明の第１実施形態に係る噴射物の漏出低減装置の作用について説明する。
図１及び図２に示すレールＲR，ＲLと車輪ＷR，ＷLとの間に発生する空転が検出されたり、非常ブレーキ装置の作動が検出されたりすると、制御装置１９が開閉部４Ｒ，４Ｌを動作させて気体噴射部２から流路３，５Ｒ，５Ｌを通じて図４に示す噴射管１０に圧縮気体が流入する。圧縮気体がオリフィス１０ａを通過すると、収容部６Ｒ，６Ｌ内の噴射物Ｍ1が吸込口１０ｃから噴射管１０内に吸い上げられて、圧縮気体とともに噴射物Ｍ1が流路１７Ｒ，１７Ｌを通じて噴射部１８Ｒ，１８ＬからレールＲR，ＲLと車輪ＷR，ＷLとの間に噴射される。その結果、レールＲR，ＲLと車輪ＷR，ＷLとの間の粘着係数が増加して、空転が防止されるとともにブレーキ性能が向上する。線路Ｒ上を鉄道車両が走行すると、この鉄道車両の台車が振動して、この台車に装着された収容部６Ｒ，６Ｌも振動する。 Next, the operation of the device for reducing the leakage of the projectile according to the first embodiment of the present invention will be described.
The control device 19 controls the opening / closing unit 4R when the idle rotation occurring between the rails R R and R L and the wheels W R and W L shown in FIGS. 1 and 2 is detected or the operation of the emergency brake device is detected. , 4L are operated, and compressed gas flows from the gas injection part 2 into the injection pipe 10 shown in FIG. 4 through the flow paths 3, 5R, 5L. When compressed gas passes through the orifice 10a, housing portion 6R, injection material M 1 in 6L is sucked up from the suction port 10c into the injection tube 10, the injection unit through the injection material M 1 is the passage 17R, 17L together with the compressed gas The fuel is injected between the rails R R and R L and the wheels W R and W L from 18R and 18L. As a result, the adhesion coefficient between the rails R R and R L and the wheels W R and W L is increased, so that idling is prevented and the brake performance is improved. When the railway vehicle travels on the track R, the carriage of the railway vehicle vibrates, and the accommodation portions 6R and 6L mounted on the carriage also vibrate.

図１０（Ｂ）に示すように、図１０（Ａ）に示す漏出低減装置２０を収容部６Ｒ，６Ｌが備えていない場合には、噴射管１０の吸込口１０ｃの下方に存在する噴射物Ｍ1の収容空間Ｓ3が広いため、この収容空間Ｓ3内の噴射物Ｍ1の総体積が大きくなる。このため、週呼ぶ６Ｒ，６Ｌが振動して収容空間Ｓ3内の噴射物Ｍ1が振動したときには、図１及び図２に示す噴射装置１が動作しておらず噴射管１０内に圧縮気体が流れていないにもかかわらず、図１０（Ｂ）に示す吸込口１０ｃから噴射物Ｍ1が噴射管１０内に漏れ出す。 As shown in FIG. 10 (B), when the housings 6R and 6L do not have the leakage reduction device 20 shown in FIG. 10 (A), the jetted material M present below the suction port 10c of the jet pipe 10 since the first accommodation space S 3 wide, the total volume of the injection was M 1 in the housing space S 3 is increased. Therefore, week referred 6R, when 6L is the injection was M 1 in the housing space S 3 vibrates and vibration, compressed gas in Figure 1 and the injection device 1 is injection pipe 10 not in operation shown in FIG. 2 Although the air does not flow, the injection material M 1 leaks into the injection pipe 10 from the suction port 10 c shown in FIG. 10 (B).

一方、図１０（Ａ）に示すように、漏出低減装置２０を収容部６Ｒ，６Ｌが備えている場合には、噴射管１０の吸込口１０ｃの下方に存在する噴射物Ｍ1の収容空間Ｓ2(Ｓ2＜Ｓ3)が狭くなるため、この収容空間Ｓ2内の噴射物Ｍ1の総体積が小さくなる。このため、収容部６Ｒ，６Ｌが振動して収容空間Ｓ2内の噴射物Ｍ1が振動したときには、図１及び図２に示す噴射装置１が動作しておらず噴射管１０内に圧縮気体が流れていなくても、図１０（Ａ）に示す吸込口１０ｃから噴射物Ｍ1が噴射管１０内に漏れ出すのを容積低減部２２Ｒ，２２Ｌが抑制する。 On the other hand, as shown in FIG. 10 (A), accommodating unit 6R leakage reduction device 20, when the 6L is provided, the housing space S of the injection material M 1 which is present below the suction port 10c of the injection pipe 10 2 (S 2 <S 3) for becomes narrow, the total volume of the injection was M 1 in the accommodating space S 2 is decreased. Thus, housing portion 6R, when 6L is the injection was M 1 in the accommodation space S 2 vibrates the vibration, compressed gas in Figure 1 and the injection device 1 is injection pipe 10 not in operation shown in FIG. 2 even if no flow, FIG. 10 (a) to indicate inlet 10c from injection material M 1 is the volume reduction unit 22R from leaking into the injection tube 10, 22L suppresses.

例えば、図１０（Ａ）に示す容積低減部２２Ｒ又は容積低減部２２Ｌの一方のみに流通部２２ｄを形成した場合や、容積低減部２２Ｒ，２２Ｌの双方に流通部２２ｄを形成しなかった場合には、収容部６Ｒ，６Ｌが振動して収容空間Ｓ2内の噴射物Ｍ1が振動すると、収容空間Ｓ1と収容空間Ｓ2との間で噴射物Ｍ1の移動が規制され噴射物Ｍ1の移動が滞る。このため、収容部６Ｒ，６Ｌが振動して収容空間Ｓ3内の噴射物Ｍ1が振動したときには、噴射装置１が動作しておらず噴射管１０内に圧縮気体が流れていないにもかかわらず、吸込口１０ｃから噴射物Ｍ1が噴射管１０内に漏れ出す可能性がある。 For example, when the circulation part 22d is formed only in one of the volume reduction part 22R or the volume reduction part 22L shown in FIG. 10A, or when the circulation part 22d is not formed in both of the volume reduction parts 22R and 22L. is accommodating portion 6R, the 6L is the injection was M 1 in the accommodation space S 2 vibrates vibrates, the housing space movement of the injection material M 1 between S 1 and the accommodation space S 2 is regulated injection matter M Movement of 1 is delayed. Thus, housing portion 6R, when 6L vibrates the injection material M 1 in the housing space S 3 vibrates, even though the compressed gas to the injection device 1 is in the injection pipe 10 not in operation is not flowing There is a possibility that the injection material M 1 may leak into the injection pipe 10 from the suction port 10 c.

図１０（Ａ）に示すように、容積低減部２２Ｒ，２２Ｌと噴射管１０との間には、この噴射管１０を中心として左右に流通部２２ｄが形成されている。このため、収容部６Ｒ，６Ｌが振動して収容空間Ｓ2内の噴射物Ｍ1が振動すると、収容空間Ｓ1と収容空間Ｓ2との間で流通部２２ｄを通じて噴射物Ｍ1が図中二点鎖線で示す矢印方向に自由に移動する。その結果、収容空間Ｓ2から収容空間Ｓ1に噴射物Ｍ1が容易に移動して、収容空間Ｓ2から吸込口１０ｃに移動してこの吸込口１０ｃから噴射管１０に漏出する噴射物Ｍ1の漏出量が低減される。噴射装置１が動作して噴射物Ｍ1が吸込口１０ｃから噴射管１０に吸い込まれて消費されると、収容空間Ｓ1から収容空間Ｓ2に流通部２２ｄを通じて図中二点鎖線で示す矢印方向に噴射物Ｍ1が容易に移動して、収容空間Ｓ1から収容空間Ｓ2に噴射物Ｍ1が供給される。 As shown in FIG. 10A, between the volume reduction parts 22R and 22L and the injection pipe 10, circulation parts 22d are formed on the left and right with the injection pipe 10 at the center. Thus, housing portion 6R, the 6L is the injection was M 1 in the accommodation space S 2 vibrates to vibrate, the injection material M 1 is in the figure through the circulation portion 22d between the housing space S 1 and the accommodation space S 2 It moves freely in the arrow direction shown by the two-dot chain line. As a result, the injected material M 1 easily moves from the accommodation space S 2 to the accommodation space S 1 , moves from the accommodation space S 2 to the suction port 10 c and leaks from the suction port 10 c to the injection pipe 10 1 leakage is reduced. The injection device 1 is operated the injection material M 1 is consumed is sucked from the suction port 10c to the injection pipe 10, an arrow shown in the drawing the two-dot chain line through the circulation portion 22d from the storage space S 1 in the accommodating space S 2 The projectile M 1 is easily moved in the direction, and the projectile M 1 is supplied from the accommodation space S 1 to the accommodation space S 2 .

図１７は、図６〜図９に示す漏出低減装置２０が収容部６Ｒに取り付けられている場合（以下、本装置取付という）と、この漏出低減装置２０が収容部６Ｒに取り付けられていない場合（以下、本装置なしという）とにおける増粘着材の噴射量と図６に示すニードル弁１４の開度との関係を示すグラフである。図１７に示す縦軸は、噴射量（g/30s）であり、横軸はニードル弁１４の開度である。図１７に示すように、増粘着材の噴射圧力が500kPaであるときにニードル弁１４の開度を5/8に調整すると、本装置取付の場合と本装置なしの場合とではいずれも噴射量が略同じになった。また、増粘着材の噴射圧力が700kPaであるときには、ニードル弁１４の開度を1/2に調整すると、本装置取付の場合と本装置なしの場合とではいずれも噴射量が略同じになった。このため、本装置取付の場合であっても本装置なしの場合と同様に、圧縮空気を送出する噴射時の噴射量が規定値を満足することが確認された。その結果、漏出低減装置２０を収容部６Ｒ，６Ｌに取り付けた場合には、ニードル弁１４の開度を調整することによって、従来の噴射装置と同様に増粘着材を噴射可能であることが確認された。   FIG. 17 shows the case where the leakage reduction device 20 shown in FIGS. 6 to 9 is attached to the accommodation portion 6R (hereinafter referred to as the present device attachment) and the leakage reduction device 20 is not attached to the accommodation portion 6R. FIG. 7 is a graph showing the relationship between the injection amount of the adhesive and the opening degree of the needle valve 14 shown in FIG. The vertical axis shown in FIG. 17 is the injection amount (g / 30 s), and the horizontal axis is the opening degree of the needle valve 14. As shown in FIG. 17, if the opening degree of the needle valve 14 is adjusted to 5/8 when the injection pressure of the adhesive is 500 kPa, the injection amount in both the case of the present device attachment and the case without the present device Became almost the same. In addition, when the injection pressure of the adhesive material is 700 kPa, if the opening degree of the needle valve 14 is adjusted to 1/2, the injection amount becomes substantially the same in both of the case where the device is attached and the case without the device. The For this reason, it was confirmed that the injection amount at the time of the injection which sends out compressed air satisfies a specified value similarly to the case without this device even in the case of this device attachment. As a result, when the leakage reduction device 20 is attached to the housing portions 6R and 6L, it is confirmed that the adhesion-promoting material can be injected as in the conventional injection device by adjusting the opening degree of the needle valve 14 It was done.

図１８は、本装置取付の場合と本装置なしの場合とにおける加振試験時の増粘着材の漏出量を示すグラフである。図１８に示す縦軸は、漏出量（g/30s）であり、横軸は漏出量の最大値、最小値及び平均値である。本装置取付の場合と本装置なしの場合とについて収容部６Ｒに加振試験を実施した。加振試験は、加振試験装置（エミック社F-40000BDH/LA-TS）を使用して、振動加速度1Gで振動周波数5,10,20Hzに変化させた加振条件の場合と、振動加速度2Gで振動周波数5,10,20,30,60,90Hzに変化させた加振条件の場合とについて実施した。図１８に示すグラフは、本装置なしの場合に最も漏出量が多かった振動加速度2Gで振動周波数10Hzの加振条件で加振したときの測定結果である。その結果、本装置取付の場合に収容部６Ｒを加振した場合と、本装置なしの場合に収容部６Ｒを加振した場合とで漏出量を比較すると、本装置なしの場合に比べて本装置取付の場合には、増粘着材の漏出量を低減可能であることが確認された。   FIG. 18 is a graph showing the amount of leakage of the adhesion-promoting material at the time of the excitation test in the case of the present device attachment and in the case of the present device absence. The vertical axis shown in FIG. 18 is the amount of leak (g / 30 s), and the horizontal axis is the maximum value, the minimum value, and the average value of the amount of leak. A vibration test was performed on the housing 6R in the case of the present device attachment and in the case of the present device absence. The vibration test is performed under vibration conditions where vibration frequency is changed to 5, 10 and 20 Hz with vibration acceleration 1 G and vibration acceleration 2 G using a vibration test apparatus (Emic Co., Ltd. F-40000 BDH / LA-TS). The vibration frequency was changed to 5, 10, 20, 30, 60, 90 Hz. The graph shown in FIG. 18 is a measurement result when vibration is generated under vibration conditions of a vibration frequency of 10 Hz with a vibration acceleration 2G in which the amount of leakage is the largest without the present apparatus. As a result, when the leakage amount is compared between the case where the storage section 6R is vibrated in the case of the present device attachment and the case where the storage portion 6R is vibrated in the absence of the present device, compared with the case where the present device is not present In the case of the installation of the device, it was confirmed that the leakage amount of the pressure-sensitive adhesive could be reduced.

次に、この発明の第２実施形態に係る噴射物の漏出低減装置の作用について説明する。
図１９及び図２０に示す線路Ｒが曲線区間であるときに、この曲線区間に鉄道車両が進入すると、鉄道車両の曲線進入が検知されたり、レールＲR，ＲLと車輪ＷR，ＷLとの間に発生する横圧が検知されたり、曲線区間進入時に発生するきしり音が検知されたりする。例えば、図１９及び図２０に示す線路Ｒが曲線区間でありレールＲLが内軌側であるときには、制御装置１９が開閉部４Ｌを動作させてレールＲLと車輪ＷLとの間に噴射装置１が噴射物Ｍ2を噴射する。その結果、内側頭側面Ｒ2とフランジ面Ｗ2との間に生じる過度の摩擦抵抗が緩和されて、曲線区間におけるレールＲR，ＲLの摩耗が防止される。 Next, the operation of the device for reducing the leakage of the projectile according to the second embodiment of the present invention will be described.
When a railway vehicle enters a curved section when the track R shown in FIGS. 19 and 20 is a curved section, the curved approach of the railway vehicle is detected, and the rails R R and R L and the wheels W R and W L The lateral pressure generated between them is detected, and the squeak noise generated when entering a curved section is detected. For example, when the line R shown in FIGS. 19 and 20 is a curved section and the rail R L is on the inner track side, the control device 19 operates the opening / closing portion 4L to inject between the rail R L and the wheel W L device 1 injects injection material M 2. As a result, are relaxed excessive frictional resistance generated between the inner head side R 2 and flange surface W 2, the rail R R in the curve section, the wear of R L can be prevented.

図３〜図１０に示す噴射管１０には小径部１０ｂが形成されているため、図８に示すようにこの小径部１０ｂの外周面と容積低減部２２Ｒ，２２Ｌの内側傾斜面との間には隙間が形成される。一方、図２１〜図２２に示す噴射管１０には図３〜図１０に示す小径部１０ｂが形成されていないため、噴射管１０の外周面と容積低減部２２Ｒ，２２Ｌの内側傾斜面とが密着してこれらの間には隙間が形成されない。図２４〜図２７に示すように、容積低減部２２Ｒ，２２Ｌの内側傾斜面には流通部２２ｈが形成されている。このため、収容部６Ｒ，６Ｌが振動して収容空間Ｓ2内の噴射物Ｍ2が振動すると、図２５に示すように収容空間Ｓ1と収容空間Ｓ2との間で流通部２２ｈを通じて噴射物Ｍ2が図中二点鎖線で示す矢印方向に自由に移動する。その結果、収容空間Ｓ2から収容空間Ｓ1に噴射物Ｍ2が容易に移動して、収容空間Ｓ2から吸込口１０ｃに移動してこの吸込口１０ｃから噴射管１０に漏出する噴射物Ｍ2の漏出量が低減される。噴射装置１が動作して噴射物Ｍ2が吸込口１０ｃから噴射管１０に吸い込まれて消費されると、収容空間Ｓ1から収容空間Ｓ2に流通部２２ｈを通じて図中二点鎖線で示す矢印方向に噴射物Ｍ2が容易に移動して、収容空間Ｓ1から収容空間Ｓ2に噴射物Ｍ2が供給される。 Since the small diameter portion 10b is formed in the injection pipe 10 shown in FIGS. 3 to 10, as shown in FIG. 8, it is between the outer peripheral surface of the small diameter portion 10b and the inner inclined surfaces of the volume reduction portions 22R and 22L. A gap is formed. On the other hand, since the small diameter portion 10b shown in FIGS. 3 to 10 is not formed in the injection pipe 10 shown in FIGS. 21 to 22, the outer peripheral surface of the injection pipe 10 and the inner inclined surfaces of the volume reduction portions 22R and 22L In close contact, no gap is formed between them. As shown in FIG. 24 to FIG. 27, the flow-through portion 22 h is formed on the inner inclined surfaces of the volume reduction portions 22 R and 22 L. Thus, housing portion 6R, the 6L is the injection was M 2 in the accommodation space S 2 vibrates to vibrate, injected through circulation portion 22h between the housing space S 1 and the accommodation space S 2, as shown in FIG. 25 object M 2 is free to move in the direction of the arrow indicated by the two-dot chain line in FIG. As a result, the injected material M 2 easily moves from the accommodation space S 2 to the accommodation space S 1 , moves from the accommodation space S 2 to the suction port 10 c and leaks from the suction port 10 c to the injection pipe 10 The amount of leakage of 2 is reduced. The injection device 1 is operated the injection material M 2 is consumed is sucked from the suction port 10c to the injection pipe 10, an arrow shown in the drawing the two-dot chain line through the circulation portion 22h from the housing space S 1 in the accommodating space S 2 and move easily injected material M 2 in a direction, the injection material M 2 is supplied from the accommodating space S 1 in the housing space S 2.

Therefore, when the housing portions 6R vibrates the injection material M 2 in the accommodation space S 2 vibrates, between the housing space S 1 and the accommodation space S 2 is injected product M 2 freely through circulation section 22h It can be moved. As a result, since the injection material M 2 from the housing space S 2 in the housing space S 1 it can be easily moved from the accommodation space S 2 to move the injection was M 2 to the suction port 10c from the suction port 10c injection Leak of the propellant M 2 into the pipe 10 can be suppressed.

(2) この第２実施形態では、噴射物Ｍ2がレールＲR，ＲLと車輪ＷR，ＷLとの間の摩擦係数を緩和させる摩擦緩和材である。このため、収容部６Ｒ内から噴射物Ｍ2が漏出して噴射物Ｍ2が無駄に消費されてしまうのを防ぐことができる。 (2) In the second embodiment, the injection material M 2 rail R R, R L and the wheel W R, is a friction material to relax the friction coefficient between the W L. Thus, injection was M 2 from the housing section 6R can be prevented from that to the injection material M 2 leak wastefully consumed.
