Description

本考案は複数の油圧アクチュエータ(油圧シリンダー、油圧モータ等をいう)を備えた船舶の油圧監視装置に関する。 The present invention relates to a marine oil pressure monitoring apparatus having a plurality of hydraulic actuators (referred to as hydraulic cylinders, hydraulic motors, etc.).

通常、船舶に設置されているウインチ、クレーン、ボートダビット、及び操舵機等には、複数の油圧アクチュエータが設けられており(例えば、特許文献1参照)、これらの油圧アクチュエータの連結構造として、直列油圧回路と並列油圧回路等がある。 Usually, a winch, a crane, a boat davit, a steering machine, and the like installed in a ship are provided with a plurality of hydraulic actuators (see, for example, Patent Document 1). There are hydraulic circuits and parallel hydraulic circuits.

直列油圧回路は複数の油圧アクチュエータを作動するバルブを直列に接続しているので、油圧回路を通過する油量は一定となり、所要動力は圧力の変動に伴って上下する。即ち、ポンプから油圧回路に流れる油は最大油量に設定するので、必要油量が少ないウインチを高負荷で使用すると、必要以上のエネルギーを消費する。また、常に油圧ポンプの最大油量が配管内を流れるので、負荷がない場合でも配管抵抗によって待機状態の所要動力は高めになるという問題がある。 Since the series hydraulic circuit is connected in series with valves that actuate a plurality of hydraulic actuators, the amount of oil passing through the hydraulic circuit is constant, and the required power rises and falls as the pressure fluctuates. That is, since the oil flowing from the pump to the hydraulic circuit is set to the maximum oil amount, when a winch with a small amount of required oil is used at a high load, energy more than necessary is consumed. In addition, since the maximum oil amount of the hydraulic pump always flows in the pipe, there is a problem that the required power in the standby state is increased due to the pipe resistance even when there is no load.

また、並列油圧回路では、各油圧アクチュエータを並列に接続し、可変容量油圧ポンプによって圧力を一定に保つように、必要な量の圧油のみを吐出しているので、各油圧アクチュエータを使用していない場合は、油圧ポンプの吐出量は約ゼロとなり、油圧ポンプの駆動用動力は最小で済み、直列油圧回路と比較すると省エネになるという利点がある。しかし、油圧ポンプからの吐出圧力は一定であるので、作動する油圧アクチュエータの動作圧力が低い場合のその差分がエネルギーロスになるという問題がある。 In the parallel hydraulic circuit, each hydraulic actuator is connected in parallel, and only the required amount of pressure oil is discharged so that the pressure is kept constant by the variable displacement hydraulic pump. If not, the discharge amount of the hydraulic pump is approximately zero, and the driving power of the hydraulic pump can be minimized, which has the advantage of saving energy compared to the series hydraulic circuit. However, since the discharge pressure from the hydraulic pump is constant, there is a problem that the difference when the operating pressure of the operating hydraulic actuator is low results in energy loss.

更に、並列式を改良した、各油圧アクチュエータの作動圧を油圧的(即ち、機械的)に検知して、可変容量油圧ポンプの吐出圧も合わせて制御する油圧式ロードセンシングシステムがある(例えば、特許文献2参照)。 Furthermore, there is a hydraulic load sensing system that improves the parallel type and detects the operating pressure of each hydraulic actuator hydraulically (that is, mechanically) and controls the discharge pressure of the variable displacement hydraulic pump together (for example, Patent Document 2).

特開平6−316292号公報JP-A-6-316292 特開平6−344991号公報JP-A-6-344991

しかしながら、前記した油圧式ロードセンシングシステムは、各油圧アクチュエータの制御弁から油圧ポンプまでの制御用の油圧配管が必要であるので、多数の油圧アクチュエータを有し、複数の油圧ポンプを並列使用する船舶では、採用が困難であった。 However, since the hydraulic load sensing system described above requires hydraulic piping for control from the control valve of each hydraulic actuator to the hydraulic pump, the ship has a large number of hydraulic actuators and uses a plurality of hydraulic pumps in parallel. So, it was difficult to adopt.

本考案はかかる事情に鑑みてなされたもので、並列配管回路を更に発展させた油圧式ロードセンシングシステム(油圧回路)において、油圧アクチュエータ、油圧ポンプ及びその制御弁を含む油圧機器の配管が容易で、かつ油圧機器の管理もできる船舶の油圧監視装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and in a hydraulic load sensing system (hydraulic circuit) in which a parallel piping circuit is further developed, piping of hydraulic equipment including a hydraulic actuator, a hydraulic pump and its control valve is easy. It is another object of the present invention to provide a ship hydraulic pressure monitoring device that can also manage hydraulic equipment.

第1〜第4の考案に係る船舶の油圧監視装置においては、各油圧アクチュエータとその切換え弁との間に圧力検出器を設け、その電気的出力を船舶内にある制御盤に導いているので、制御用の油圧配管を設ける必要が無くなり、油圧回路の工事の簡略化が可能となる。
また、各油圧アクチュエータの稼働圧力、即ち稼働状況をモニターによって視認できるので、各油圧アクチュエータの監視ができる。
In the ship hydraulic pressure monitoring apparatus according to the first to fourth devices, a pressure detector is provided between each hydraulic actuator and its switching valve, and its electrical output is led to a control panel in the ship.

続いて、添付した図面を参照しながら、本考案を具体化した実施の形態について説明する。
図1に示すように、本考案の一実施の形態に係る船舶の油圧監視装置10は、複数(この実施の形態では4)の油圧ポンプ11を有する油圧源12と、油圧源12にそれぞれ切換え弁13を介して接続され、船舶の各機器の駆動源となる複数の油圧アクチュエータ14と、各切換え弁13と油圧アクチュエータ14の高圧油給油側との間に設けられた圧力検出器15とを有する。各圧力検出器15からの電気信号(電気的出力)は、船舶内にある制御盤17の油圧制御部18に入力され、電磁比例式圧力制御弁16を介して各油圧ポンプ11の制御を行っている。
Next, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, a ship hydraulic pressure monitoring device 10 according to an embodiment of the present invention is switched to a hydraulic pressure source 12 having a plurality (four in this embodiment) of hydraulic pumps 11 and a hydraulic pressure source 12. A plurality of hydraulic actuators 14 that are connected via a valve 13 and serve as a drive source for each device of the ship, and a pressure detector 15 provided between each switching valve 13 and the high-pressure oil supply side of the hydraulic actuator 14 Have. An electric signal (electrical output) from each pressure detector 15 is input to a hydraulic control unit 18 of a control panel 17 in the ship, and controls each hydraulic pump 11 via an electromagnetic proportional pressure control valve 16. ing.

油圧ポンプ11としては、並列接続された可変容量型の油圧ポンプが使用され、これら油圧ポンプ11は、電磁比例式圧力制御弁16によって制御され、吐出する圧油の圧力を調整して各切換え弁13に送っている。切換え弁13は通常はマニアルバルブ(電磁弁でも可能)で、ハンドル操作によって油圧アクチュエータ14に油の送受を行っている。 As the hydraulic pump 11, variable displacement hydraulic pumps connected in parallel are used. These hydraulic pumps 11 are controlled by an electromagnetic proportional pressure control valve 16, and adjust the pressure of the pressure oil to be discharged to switch each switching valve. It is sent to 13. The switching valve 13 is normally a manual valve (can be an electromagnetic valve), and sends and receives oil to and from the hydraulic actuator 14 by operating the handle.

圧力検出器15は各油圧アクチュエータ14の作動圧力を検知し、その電気信号を制御盤17に送っている。油圧アクチュエータ14は、例えば油圧シリンダーや油圧モータからなって、圧力検出器15は各油圧アクチュエータ14の負荷に対応した圧力を検出している。制御盤17には、油圧制御部18が設けられ、各圧力検出器15によって検出された圧力データを記録すると共に、記録したデータを時間と共にモニター19に出力している。ここで、作動圧力のデータと時間とで各油圧アクチュエータ14の稼働状況を判断できる。更に、油圧制御部18は、各圧力検出器15で検出された圧力(油圧アクチュエータ14の作動油圧)のうち最大圧力(油圧)Pを検知し、電磁比例式圧力制御弁16に送って油圧源12の圧力が最大圧力Pになるように制御している。また、油圧制御部18では、各油圧アクチュエータ14の圧力と、作動時間から累積稼働時間を演算し、モニター19に、各油圧アクチュエータ14の作動圧力、及び累積稼働時間を表示している。 The pressure detector 15 detects the operating pressure of each hydraulic actuator 14 and sends the electrical signal to the control panel 17. The hydraulic actuator 14 is composed of, for example, a hydraulic cylinder or a hydraulic motor, and the pressure detector 15 detects a pressure corresponding to the load of each hydraulic actuator 14. The control panel 17 is provided with a hydraulic pressure control unit 18 that records pressure data detected by each pressure detector 15 and outputs the recorded data to the monitor 19 with time. Here, the operating status of each hydraulic actuator 14 can be determined from the data and time of the operating pressure. Further, the hydraulic pressure control unit 18 detects the maximum pressure (hydraulic pressure) P among the pressures detected by the pressure detectors 15 (the hydraulic pressure of the hydraulic actuator 14), and sends it to the electromagnetic proportional pressure control valve 16 to send the hydraulic pressure source. The pressure of 12 is controlled to be the maximum pressure P. The hydraulic control unit 18 calculates the cumulative operating time from the pressure and operating time of each hydraulic actuator 14 and displays the operating pressure and cumulative operating time of each hydraulic actuator 14 on the monitor 19.

従って、最大圧力Pより低い圧力で作動する油圧アクチュエータ14については、切換え弁13でその圧力調整を行い、油圧アクチュエータ14が所定の負荷圧力を維持できる構造となっている。
ここで、例えば、新たな切換え弁13で負荷の選択が行われ、圧力検出器15によって測定された各油圧アクチュエータ14の圧力が最大圧力Pより低い圧力になった場合は、最大圧力P1(<P)を検知して、油圧制御部18で電磁比例式圧力制御弁16を制御して圧力源12の圧力をP1にすると共に、各油圧ポンプ11からの供給圧をP1に下げている。
これによって、油圧ポンプ11からの圧力が迅速に切り替わるので、並列油圧回路タイプの油圧構成よりエネルギー消費が減少し、かつ各圧力検出器15からの信号はケーブル内を通過する電気信号となる。従って、電気で信号の授受ができるので、従来の制御用の油圧配管を用いる場合より、工事が容易となる。
Therefore, the hydraulic actuator 14 that operates at a pressure lower than the maximum pressure P is adjusted by the switching valve 13 so that the hydraulic actuator 14 can maintain a predetermined load pressure.
Here, for example, when the load is selected by the new switching valve 13 and the pressure of each hydraulic actuator 14 measured by the pressure detector 15 is lower than the maximum pressure P, the maximum pressure P1 (< P) is detected, and the hydraulic proportional pressure control valve 16 is controlled by the hydraulic pressure control unit 18 to set the pressure of the pressure source 12 to P1, and the supply pressure from each hydraulic pump 11 is reduced to P1.
As a result, the pressure from the hydraulic pump 11 is quickly switched, so that energy consumption is reduced as compared with the hydraulic configuration of the parallel hydraulic circuit type, and the signal from each pressure detector 15 becomes an electrical signal passing through the cable. Therefore, since signals can be exchanged by electricity, the construction becomes easier than when conventional hydraulic piping for control is used.

また、前述のように、制御盤17(詳細には油圧制御部18)では、圧力検出器15からの出力を積算して、各油圧アクチュエータ14について、使用開始時(所謂、船舶が最初に進水した時)からの累積稼働時間(積算稼働時間)を演算してメモリーにデータとして記録しモニター19に表示している。
これによって、各油圧アクチュエータ14の使用時間が判り、事故が発生する前に、各油圧アクチュエータ14の点検及び交換時期を推定できる。
更に、制御盤17の油圧制御部18は、各油圧ポンプ11の累積稼働時間を演算して、制御盤17に記憶し、モニター19に表示する。これによって、油圧ポンプ11の保守点検、交換を行うことができる。
In addition, as described above, the control panel 17 (specifically, the hydraulic control unit 18) integrates the outputs from the pressure detectors 15 so that each hydraulic actuator 14 is used at the start of use (the so-called ship first advances). Cumulative operating time (accumulated operating time) from when the water is discharged is calculated, recorded as data in the memory, and displayed on the monitor 19.
As a result, the usage time of each hydraulic actuator 14 is known, and the inspection and replacement timing of each hydraulic actuator 14 can be estimated before an accident occurs.
Further, the hydraulic control unit 18 of the control panel 17 calculates the cumulative operating time of each hydraulic pump 11, stores it in the control panel 17, and displays it on the monitor 19. Thereby, maintenance inspection and replacement of the hydraulic pump 11 can be performed.

図2(B)には、従来例に係る直列油圧回路の油の流量、圧力、所要動力の関係を示すが、油圧アクチュエータの流量には関係なく(従って、少量であっても)一定の動力が必要となる。
図2(C)には、従来例に係る並列油圧回路の油の流量、圧力、所要動力の関係を示すが、個々の油圧アクチュエータの使用圧力には関係なく、全体の流量に応じた所要動力が必要となる。
FIG. 2B shows the relationship between the oil flow rate, the pressure, and the required power of the series hydraulic circuit according to the conventional example, but the constant power regardless of the flow rate of the hydraulic actuator (thus, even a small amount). Is required.
FIG. 2 (C) shows the relationship between the oil flow rate, pressure and required power of the parallel hydraulic circuit according to the conventional example, but the required power corresponding to the overall flow rate regardless of the operating pressure of each hydraulic actuator. Is required.

一方、図1に構成を示す船舶の油圧監視装置10を用いたロードセンシングタイプの油圧回路においては、図2(A)に示すように、所要動力が、圧力と油の流量の関数となって、圧力と油の流量のいずれかが小さい場合であっても所要動力は減少する。しかも、多数の油圧アクチュエータがあっても制御用の油圧配管は必要でないので、油圧回路の簡略化が図れる。 On the other hand, in the load sensing type hydraulic circuit using the ship hydraulic pressure monitoring device 10 shown in FIG. 1, the required power is a function of the pressure and the oil flow rate as shown in FIG. The required power decreases even if either the pressure or the oil flow rate is small. In addition, even if there are a large number of hydraulic actuators, hydraulic piping for control is not necessary, so that the hydraulic circuit can be simplified.

本考案は前記した実施の形態に限定されるものではなく、本考案の要旨を変更しない範囲でその構成を変更することもできる。例えば、油圧ポンプの個数、油圧アクチュエータの個数には本考案は限定されない。
また、油圧制御部は、各圧力検出器からの入力信号をデジタル変換して、例えば、マイクロコンピュータ、プログラマブルコントローラ等で、最大の圧力値及び各油圧アクチュエータの累積稼働時間を演算し、モニターに表示することもできる。更に、制御盤に接続されるモニターは用途に応じて複数でもよい。
The present invention is not limited to the above-described embodiment, and the configuration thereof can be changed without changing the gist of the present invention. For example, the present invention is not limited to the number of hydraulic pumps and the number of hydraulic actuators.
The hydraulic control unit digitally converts the input signal from each pressure detector, calculates the maximum pressure value and the cumulative operating time of each hydraulic actuator, for example, with a microcomputer, programmable controller, etc., and displays them on the monitor You can also Further, a plurality of monitors connected to the control panel may be used depending on the application.
