従来の欠点を解消したものである。 Therefore, in this invention, a refueling tank is installed at a location lower than the oil tank of the main equipment that receives refueling, and when the main equipment is in operation or stopped, the oil tank is filled from the main equipment's oil tank to the tank due to the head difference, and the main equipment can be refueled in an emergency. When doing so, we decided to create a simple and compact device that can be provided at low cost by allowing lubricating oil to be pumped from the refueling tank to the lubrication system of the main equipment using gas at the minimum pressure necessary for refueling. Therefore, the oil supply system of the present invention is adapted to the requirements of an auxiliary oil supply system and eliminates the drawbacks of the conventional oil supply system.

3 is configured such that when the forced refueling circulation system 2 is operating normally, the compressed gas is released from the refueling tank 8 and the pressure becomes atmospheric pressure inside the refueling tank 8, as shown in the figure. When the oil supply circulation system 2 fails, the supply/exhaust valve 13 is activated to introduce compressed gas into the oil tank 8 from the pipe line 12b through the pipe line 12a.

から構成されている。 The device for feeding lubricating oil from the oil supply tank 8 to the lubrication system 5 of the main equipment 1 using the compressed gas described above includes a pipe line 14 that communicates the oil supply tank 8 and the lubrication system 5, and the forced oil supply circulation. This pipe line 1 is designed to prevent the lubricating oil pumped by the pump P from flowing back into the pipe line 14 when the device 2 is in normal operation.
4, and a flow rate control valve 16 interposed in the pipe line 14 to adjust the flow rate of lubricating oil sent from the oil supply tank 8 in an emergency.

は循環している。 To explain the operation of the emergency refueling device 7 configured as described above and the forced refueling circulation device 2 described above, now,
When oil is sent to the lubrication system 5 of the main equipment 1 when the forced oil circulation device 2 is in a normal state, a pump P operated by an electric motor M sucks and pressurizes the oil in the oil tank 3 and passes it through the pipes 4a and 4b. Supply oil to the lubrication system 5. The lubricating oil supplied to the lubricating system 5 returns to the oil tank 3 once it has fulfilled its role. Normally, lubricating oil is circulated in this way.

給油される。 Then, due to a power outage or a failure of the electric motor M or pump P, it becomes impossible to supply lubricating oil to the main equipment 1.
Then, the main device 1 receives the stop command and stops after a certain period of time. However, since the forced lubrication circulation device 2 does not work from the time the main device 1 receives the stop command until the main device 1 stops, the main device 1 is in an unlubricated state. To prevent this, the supply/exhaust valve 13 is activated when the system stops abnormally due to a power outage or a failure of the forced oil supply/circulation system 2.
When the supply/exhaust valve 13 operates, the compressed gas pipe line 12a and the pipe line 12b are brought into communication with each other, so that the compressed gas enters the oil tank 8, which was at atmospheric pressure, and the lubricating oil in the oil tank 8 The lubricating oil reaches the pipe line 14, the flow rate of which is adjusted by the flow rate control valve 16, and the lubricating oil is supplied from the pipe line 14 to the lubrication system 5 of the main equipment 1.
したがつて、主機器１は焼付いたりすることが
ない。 Therefore, the main device 1 will not be seize up.
なお、圧縮ガスにより加圧された潤滑油は管路

確実に潤滑系統５へ給油タンク８から給油するこ
とができる。 Note that the lubricating oil pressurized by the compressed gas tries to flow to the pipe line 10 and the pipe line 4b of the forced oil supply circulation device 2, but it is blocked by the check valves 6 and 11, so that the lubricating oil is reliably supplied to the lubrication system 5. Refueling can be done from tank 8.
そして、主機器１が完全に停止しあるいは停電

８内は再び大気圧になる。 Then, when the main equipment 1 completely stops or there is a power outage or the forced refueling circulation device 2 returns to normal, the supply/exhaust valve 13 returns to its original position, and the compressed gas in the refueling tank 8 is released into the atmosphere. The pressure inside the fuel tank 8 becomes atmospheric again.
したがつて油槽３からは再び給油タンク８内に
油が補充されることになる。 Therefore, oil is replenished from the oil tank 3 into the oil supply tank 8 again.
なお前述した圧縮ガスの圧力は、通常の潤滑油
の給油圧に合せたものでよく、一般には給油圧は
低いので圧縮ガススの圧力は通常10Kg／cm2以下で
よく安全である。 Note that the pressure of the compressed gas mentioned above may be adjusted to the oil pressure of the normal lubricating oil supply, and since the oil pressure of the oil supply is generally low, the pressure of the compressed gas is normally 10 kg/cm 2 or less, which is safe.

急補給を行うことが可能となる。 As mentioned above, the lubricating oil supply device of the present invention has the following features:
An emergency oil supply tank, which is smaller than the oil tank of the main equipment and is connected to a compressed gas supply source via a supply/exhaust valve, is installed below the main equipment that has a lubrication system that is supplied with oil by a forced oil circulation system. A refueling device is installed, and the refueling tank is connected to the oil tank of the main equipment via a check valve that allows oil to flow from the oil tank due to a head difference, and furthermore, the oil tank is connected to the oil tank of the main equipment through a check valve that allows oil to flow from the oil tank due to a head difference. They are connected via a check valve and a flow rate control valve that allow flow to the lubrication system, and when the forced oil supply circulation device stops abnormally, the supply/exhaust valve is operated to connect the compressed gas supply source and the oil supply tank. Since the structure is configured to communicate with The pressurized gas is used to supply the lubrication system, making it possible to perform emergency oil replenishment using a simple mechanism.

な量の潤滑油を潤滑系統に供給することができ
る。即ち、正常運転時及び緊急時とに拘わらず確
実な給油が行えることになる。 Furthermore, the oil supply tank, which is provided separately from the oil tank, is smaller than the oil tank, so in an emergency, the pressurizing area is smaller than a device that directly pressurizes the oil tank with compressed gas and sends lubricating oil. Therefore, oil can be quickly replenished without any time delay, and the amount of compressed gas to be pressurized can be small. In addition, a check valve is installed in the path that replenishes oil from the oil tank to the oil supply tank by head, so when the forced oil supply circulation system stops due to an abnormality, compressed gas is used to send lubricant from the oil supply tank to the lubrication system of the main equipment. At this time, it is possible to reliably supply the lubricating oil without causing it to flow back into the oil tank. In addition, a check valve and a flow rate control valve are also provided in the path connecting the oil tank and the lubrication system, so that when the forced oil circulation system is operating normally, some of the lubricating oil There is no possibility of a backflow to the oil supply tank, and in an emergency, an appropriate amount of lubricating oil can be supplied to the lubrication system. That is, reliable refueling can be performed regardless of whether the vehicle is in normal operation or in an emergency.
また、圧縮ガスにより給油タンク内の潤滑油を
主機器の潤滑系統へ送るようにしたので、緊急時
は給排気弁のみを作動させるだけで即主機器に油
を補給できるので主機器を焼付かせたりすること
がない。 In addition, compressed gas is used to send the lubricating oil in the oil supply tank to the main equipment's lubrication system, so in an emergency, oil can be immediately refilled by simply operating the supply/exhaust valve, thereby preventing the main equipment from seizing up. There is nothing to do.
さらに圧縮ガスは給油圧に合せた圧力でよいの
でガス圧力を低くすることができ安全であるとと
もに、圧力容器を特に堅牢にしたりする必要がな
いので重量を軽減化することができしたがつて材
料費を安くすることができる。 Furthermore, since the compressed gas only needs to be at a pressure that matches the supply oil pressure, the gas pressure can be lowered, making it safer, and there is no need to make the pressure vessel particularly robust, reducing weight. Costs can be reduced.

と、さらに本考案は油槽自身を小型にするのでは
なく、別に設けた給油タンクをこの油槽に比べて
小型にするという構成を採用している。 The invention of JP-A No. 52-31203 directly pressurizes the oil tank of the main equipment with compressed gas. In addition, the present invention does not make the oil tank itself smaller, but instead adopts a configuration in which a separately provided oil tank is made smaller than the oil tank.

速な油の補給が行なえ、また加圧する圧縮ガス量
も少なくて済むという特開昭52−31203号発明に
はない優れた作用効果を有するのである。 In other words, by making the separately provided oil supply tank smaller than the oil tank of the main equipment, this invention reduces the pressurizing area for compressed gas, which enables quick oil replenishment in an emergency. It has an excellent effect that the invention of JP-A-52-31203 does not have, in that it requires less gas.

条件下では、タンク容量が小さいほどタンク内の

ずることなく、給油することができる。 Further, there is a limit to the amount of pressurized gas (the amount of gas that can be supplied within a unit time) to be supplied to the oil supply tank in order to pressurize the lubricating oil in the tank. In other words, only a predetermined amount of pressurized gas can be supplied, and under this condition, the smaller the tank capacity, the faster the pressure inside the tank can be increased. Refueling can be done without any delay.
仮りに、特開昭52−31203号発明において主機

急時には迅速に対処できるようにしたものであ
り、単に油槽を小型にしただけのものとは意味が
違うのである。 If the invention of JP-A-52-31203 were to reduce the size of the oil tank of the main equipment itself, the small capacity would impede the lubrication function during normal operation. The present invention is designed to provide adequate lubrication during normal operation by downsizing the separate oil tank, while also making it possible to respond quickly in emergencies. It has a different meaning from just that.
このように本考案は、構造簡単でしかも低圧力
にして安価に提供できるので、補助的な給油装置
としての条件を満足するものである。 As described above, the present invention has a simple structure, low pressure, and can be provided at low cost, so it satisfies the requirements as an auxiliary oil supply device.
