Description
クローラ式走行装置を備えたバックホーなどの作業車に連結器を介してトロを連結して構成した軌道用作業列車の前記トロは、前記作業車に搭載した油圧ユニットに連けいした油圧ブレーキを備えているが、本発明は該油圧ブレーキの油圧路装置に関するものである。 The toro of a track work train configured by connecting a toro via a coupler to a work vehicle such as a backhoe equipped with a crawler type traveling device includes a hydraulic brake connected to a hydraulic unit mounted on the work vehicle. However, the present invention relates to a hydraulic path device for the hydraulic brake.
前記の油圧路装置は、トロ側の油圧ブレーキに通じる油圧管路の端末に逆止弁を備えた接続手段を装置し、該接続手段にトロ側の油圧ブレーキに連通させた油圧ホースの端末を接続して構成する一方、トロの車輪は油圧ブレーキに油圧がかかっていないときは制動され、油圧をかけたときは走行状態になるようになっている。 In the hydraulic path device, a connecting means having a check valve is provided at a terminal of a hydraulic line leading to a hydraulic brake on the toro side, and a terminal of a hydraulic hose connected to the hydraulic brake on the toro side is connected to the connecting means. On the other hand, the wheels of the Toro are braked when no hydraulic pressure is applied to the hydraulic brake, and are in a running state when the hydraulic pressure is applied.
従来の油圧路装置は前記の通りの構成であるので、ブレーキ装置に油圧をかけた状態のとき、すなわち走行状態下にあるとき、ホース端末が何等かの原因で、例えば、連結器が外れるなどでカプラ等の接続手段から離れたり、ホースが切断したりしても、逆止弁の存在により油圧が油圧管路内に残り、ブレーキを作動させることができずにトロが逸走し、殊に、傾斜地等でこのような事態が生じたときは、大事故に直結しかねない。 Since the conventional hydraulic path device is configured as described above, when hydraulic pressure is applied to the brake device, that is, when it is in a running state, the hose terminal is disconnected for some reason, for example, the coupler is disconnected, etc. Even if the connecting means such as the coupler is separated or the hose is disconnected, the hydraulic pressure remains in the hydraulic pipe line due to the presence of the check valve, and the brake can not be operated and the toro runs away. If such a situation occurs on a slope, it may directly lead to a major accident.
本発明は、斯様な常況に対処できる軌道用作業列車におけるトロの油圧ブレーキの油圧路装置を提供すべく創案したものである。 The present invention was devised to provide a hydraulic passage device for a Toro hydraulic brake in a work train for tracks that can cope with such a normal situation.
ブレーキに油圧がかかっていないときは車輪が制動され、油圧をかけたときは走行状態になるようにした、作業車に連結装置を介してトロを連結した軌道用作業列車において、前記作業車に油圧ユニットを搭載し、該油圧ユニットと前記トロに設けた車輪制動用のブレーキの油圧管路を、油圧ホースを介して接続し、該油圧ホースと前記油圧管路の間に開閉弁を設けた構成としたものである。
In a work train for a track in which a wheel is braked when no hydraulic pressure is applied to the brake and a toro is connected to the work vehicle via a connecting device, the vehicle is in a running state when the hydraulic pressure is applied. A hydraulic unit is mounted, and the hydraulic line of the brake for wheel braking provided in the toro is connected via a hydraulic hose, and an open / close valve is provided between the hydraulic hose and the hydraulic line. It is a configuration.
本発明によれば、開閉弁を開放すると油圧ユニットからの油圧は油圧ホースと油圧管路を経てブレーキに作用してこれを解除して作業列車を走行状態に行うことができ、この走行状態時に、油圧ホースが切断等しても管路内の油圧は該切断部からの駆動油の漏出により、直ちに減圧され、従って、ブレーキ装置が作動し、トロの逸走を確実に防ぐ、油圧路装置を提供できる。 According to the present invention, when the on-off valve is opened, the hydraulic pressure from the hydraulic unit can act on the brake via the hydraulic hose and the hydraulic line to release the brake, and the work train can be put into the running state. Even if the hydraulic hose is cut off, the hydraulic pressure in the pipeline is immediately reduced by the leakage of the drive oil from the cutting section, and therefore the brake device is activated and the hydraulic path device that reliably prevents the toro from running away. Can be provided.
図面は本発明に係る軌道用作業列車におけるトロの油圧ブレーキの油圧路装置の一実施例を示し、図１は本発明装置を適用した軌道用作業列車の略示説明図、図２はトロの底面図である。 The drawings show an embodiment of the hydraulic path device of the hydraulic brake of Toro in the track work train according to the present invention, FIG. 1 is a schematic explanatory view of the track work train to which the device of the present invention is applied, and FIG. It is a bottom view.
図中、１は作業車（クローラ走行装置を備えた軌陸両用の作業車などで、ここでは、トロの走行駆動車となるものであれば良い）で、油圧ユニット２を搭載し、該油圧ユニット２は運転席に備えた操作装置によって制御するようにしてある。 In the figure, reference numeral 1 denotes a work vehicle (a road-rail work vehicle equipped with a crawler travel device, etc., which may be a Toro travel drive vehicle here), which is equipped with a hydraulic unit 2, 2 is controlled by an operating device provided in the driver's seat.
３はトロで、トロ３は連結装置４を介して前記作業車１に連結し、作業車１と共に軌道用作業列車を構成する。 Reference numeral 3 denotes a toro, and the toro 3 is connected to the work vehicle 1 via a connecting device 4 and constitutes a track work train together with the work vehicle 1.
連結装置４は、トロ３の先端と作業車１の後端のそれぞれに設けた連結器４ａ，４ａと、該連結器４ａ，４ａを接続する連結棒４ｂで構成し、この連結装置４を用いてトロ３の後側に他のトロを連結できるようにしてある。 The connecting device 4 includes connecting devices 4a and 4a provided at the front end of the toro 3 and the rear end of the work vehicle 1, and a connecting rod 4b for connecting the connecting devices 4a and 4a. Thus, another Toro can be connected to the rear side of Toro 3.
また、トロ３は作業車１に搭載した前記油圧ユニット２と油圧ホース（ゴム製であるが樹脂製でも良い）６を介して連通する油圧管路７を備え、油圧管路７は一端を開閉弁８を介して前記油圧ホース６に接続し、他の一端をトロ３に装置したシリンダ９に連通させ、シリンダ９はピストン棒９ａにおいてブレーキ装置１０の作動板１０ａに連けいしてある。
The toro 3 includes a hydraulic line 7 that communicates with the hydraulic unit 2 mounted on the work vehicle 1 via a hydraulic hose (made of rubber or resin) 6, and the hydraulic line 7 opens and closes one end. The other end of the
ブレーキ装置１０は、トロ３に揺動自在に枢着した前記作動板１０ａの一端をリンク機構１０ｂの一端に連けいさせ、リンク機構１０ｂの他の一端を揺動材１０ｃに接続し、揺動材１０ｃの先端に、トロ３の車軸１１に設けたディスク１０ｅを接離するブレーキパッド１０ｄを設けて構成したものである。
The
また、前記開閉弁８は、外部からの操作レバー８ａの操作によってホース６と油圧管路７間を開閉し、油圧ユニット５、油圧ホース６および油圧管路７とで成す油圧路の開閉を行う。
The on-off valve 8 opens and closes the
なお、油圧ホース６は油圧管路７の端末と差し込み式の接続手段を利用すると、油圧管路７との接続作業を簡単に行うことができ、実施例の場合は、逆止弁を備えたカプラー（前記差し込み機能を備えた）を用い、逆止弁に油圧路に備わせて透孔を開設して逆止弁としての機能を喪失させて単に油路の開閉機能が行えるように加工したものを用いている。要するに、開閉弁は、ホース６側から油圧の開閉を行なえるものであれば良い。
The
そして、操作レバー８ａを操作して閉状態から開状態に開閉弁８を開放すると、油圧ユニット５からの油圧が油圧ホース６、油圧管路７を順次経てシリンダ９に注入され、その結果、リンク機構１０ｂが作動してブレーキパッド１０ｄによって車軸（輪）を制動状態から開放し、車輪１３すなわち作業車１とトロ３で成る作業列車は軌条上を自在に走行できる状態となる。
When the operation lever 8a is operated to open the on-off valve 8 from the closed state to the open state, the hydraulic pressure from the hydraulic unit 5 is sequentially injected into the cylinder 9 through the
そして、走行中に何等かの原因でホース６が損傷を受けると、該損傷部から駆動油が漏出し、漏出と同時に油圧がなくなり、該油圧の喪失をシリンダ９が検出してリンク機構１０ｂに伝え、ブレーキパッド１０ｄによってディスク１０ｅが挟持され、所謂ブレーキがかかってトロ３の移動が規制されるのである。
