この考案は、水圧力によりピストンを作動させるピスト
ン装置の安全機構解除装置に関し、使用直前の安全機構
を、海水中等の高原力のもとにおいてもその圧力とは無
関係に容易に解除できるようにすることを目的とする。[Detailed description of the invention] This invention relates to a safety mechanism release device for a piston device that operates a piston by water pressure, and the safety mechanism can be released immediately before use, regardless of the pressure, even under plateau forces such as seawater. The purpose is to make it easy to release.
従来、海水中等の水圧力によりピストンを作動させるピ
ストン装置に使用される安全機構は、その装置の使用直
前に陸上において、安全せんを抜き取って解除されてい
る。Conventionally, a safety mechanism used in a piston device that operates a piston by the pressure of water such as seawater is released by removing the safety on land immediately before using the device.
しかし、装置の使用目的によっては、高圧力のもとで安
全機構を解除する必要が生じている。However, depending on the intended use of the device, it becomes necessary to release the safety mechanism under high pressure.
とこらで、前記装置の安全機構の解除に際し、安全機構
を構成するピストン軸に対し直角方向に装着された安全
せんは、周囲の圧力の高低によりその引き抜き荷重に大
小を生ずる。When the safety mechanism of the device is released, the pullout load of the safety lock, which is mounted perpendicularly to the piston shaft constituting the safety mechanism, varies depending on the level of surrounding pressure.
そして、海水中等高圧力のもとで安全機構を解除する場
合、海水の圧力により安全せんの弓き抜き荷重が犬ぎく
なり、引き抜き操作が困難であり、引き抜き操作自体に
特別の装置を付加する必要がある。When the safety mechanism is released under high pressure such as seawater, the pressure of the seawater causes the force of the safety bow to be pulled out, making it difficult to pull out the bow, and a special device must be added for the pulling out operation itself. There is a need.

供するものである。This idea was made with the above points in mind,
The upper part of the cylinder body containing the main piston, which is urged upward by a force smaller than the water pressure in the water in which the piston device is installed, is penetrated through through holes horizontally provided on both sides of the cylinder body. A safety piston is provided so as to be movable in a horizontal direction, and the safety piston has a thick shaft portion and a thin shaft portion,
A locking part for the safety piston is provided at the upper part of the main piston, and the locking part has a fitting hole into which the thick shaft part is fitted in a horizontal direction, and a fitting part from the fitting hole to the top surface of the locking part. Only the narrow shaft part communicates with the insertion groove through which it can be inserted in the vertical direction, and only when the thick shaft part is inserted into the insertion hole of the locking part can the safety piston be inserted from the through hole. A release spring is provided with a sealing that prevents water from entering the cylinder body, and biases the safety piston in one direction between the stopper attached to the safety piston and the locking part. and a removable safety screw between the safety piston and the cylinder body that prevents the operation of the release spring and maintains the state in which the thick shaft portion is fitted into the insertion hole. A safety mechanism release device for a piston device is provided.
したがって、海水中等の高圧力のもとにおしても、ピス
トン装置の周囲の圧力とは無関係に、安全せんの引き抜

つぎに海水中等においで、ピストン装置の使用に際し、
安全せん１８を手動あるいは機械的、電気的手段により
引き抜くと、解除用ばね１７により安全ピストン１０が
左方に移動し、太軸部１１が嵌挿孔１４から抜は出ると
ともに、細軸部１２が嵌挿孔１４に位置するため、係止
部１３と安全ピストン１０との係止が解かれる。Next, when using the piston device in seawater etc.
When the safety piston 18 is pulled out manually or by mechanical or electrical means, the safety piston 10 moves to the left by the release spring 17, the thick shaft portion 11 comes out of the insertion hole 14, and the thin shaft portion 12 is located in the insertion hole 14, so that the locking portion 13 and the safety piston 10 are unlocked.
