Description

円形マンホールには、蓋が1枚の物と、2枚の物が有ります。2枚式の物は、通常親子蓋と言います。 Circular manholes have one lid and two. The two-piece type is usually called the parent-child lid.

通常の点検は、子蓋を開けて行います。メンテナンス作業やポンプ入替え作業の時に親蓋を開けます。 Normal inspection is performed with the child lid open. Open the main lid for maintenance work or pump replacement work.

子蓋を開けた時は、孔が小さいし、マンホールの出入りもそんなに恐怖感は、有りません。 When the lid is opened, the hole is small and there is no fear of entering and exiting the manhole.

親蓋を開けると大きな孔が出現します。暗くて大きな孔で、異物の異臭等も有りますし、恐怖感を覚えます。 A large hole appears when the lid is opened. It is a dark, large hole with foreign odors and a sense of fear.

マンホールの蓋を開けた時の恐怖感を緩和するために、いろんな安全対策品が作られてきました。 In order to alleviate the fear of opening the manhole cover, various safety measures have been made.

特開2009-256877号は、マンホール用の落下防止兼補助梯子用中蓋が、述べられています。 Japanese Unexamined Patent Publication No. 2009-256877 describes a fall prevention and auxiliary ladder inner lid for manholes.

特開2004-3270号は、マンホール用落下防止装置が述べられています。 JP 2004-3270 describes a fall prevention device for manholes.

マンホールの蓋を開けた時の落下防止装置の安全性をもっと高める。 Increase the safety of the fall prevention device when the manhole cover is opened.

親子フタ式のマンホールにおいて、子蓋を開けた時の落下防止は、特開2009-256877号のマンホール用の落下防止兼補助梯子用中蓋が、ほとんどのマンホールに付いているので、落下防止と梯子装置による昇降が、万全と考えられます。 In the manhole of the parent and child lid type, the fall prevention when the child lid is opened is because the fall prevention and auxiliary ladder inner lid for manhole of JP-A-2009-256877 is attached to most manholes. It is considered that raising and lowering with a ladder device is perfect.

ところが、親蓋を開けると、子蓋と特開2009-256877号のマンホール用の落下防止兼補助梯子用中蓋が、一緒に付いて行ってしまうので、落下防止装置も梯子もなくなり、マンホールの大きな孔が、出現します。非常に恐怖感が高まります。親子蓋式マンホールで、親蓋を開けた時でも、落下防止装置が存在し、落下から守ってくれ、マンホール槽内への昇降もスムーズに行える梯子が、存在するようにする事が課題です。 However, when the main lid is opened, the child lid and the fall prevention and auxiliary ladder inner cover for the manhole disclosed in JP-A-2009-256877 are attached together. A large hole appears. I feel very frightened. The challenge is to make sure that there is a ladder with a fall-prevention device that protects against falling even when the lid is opened in a man-and-can lid manhole, and that can be smoothly raised and lowered into the manhole tank.

マンホールの内部の上部にタラップが、有ります。タラップと真反対の位置の上部にフック留め金具がどのマンホールにも付いています。マンホールの蓋と干渉しない、マンホールの蓋の直ぐ下に、落下防止用中蓋を取り付けます。
子蓋を開けた時に、下に子蓋用落下防止装置兼補助梯子が現れ、落下防止します。引き起こせば、梯子となり、安全に昇降出来ます。親蓋を開ければ、今までの、何もない状態でいきなり孔が出現するのでなく、親蓋用落下防止装置兼補助梯子、子蓋用落下防止装置兼補助梯子と外周安全補助装置が出現します。子蓋用落下防止装置兼補助梯子でも親蓋用落下防止装置兼補助梯子でも、引き起こせば、安全に昇降出来ます。親蓋用落下防止装置兼補助梯子、子蓋用落下防止装置兼補助梯子と外周安全補助装置は、いずれも、簡単に取り外しが出来ます。 There is a trap at the top inside the manhole. A hook clasp is attached to every manhole at the top opposite to the wrap. Attach the fall prevention inner lid directly below the manhole cover that does not interfere with the manhole cover.
When the child lid is opened, the child lid fall prevention device and auxiliary ladder appear below to prevent the child lid from falling. If you raise it, it will become a ladder and you can move up and down safely. If the main lid is opened, holes will not appear suddenly in the state of nothing until now, but a fall prevention device / auxiliary ladder for the main lid, a fall prevention device / auxiliary ladder for the child lid, and an outer peripheral safety auxiliary device will appear. The Both the fall prevention device and auxiliary ladder for the child lid and the fall prevention device and auxiliary ladder for the parent lid can be raised and lowered safely. The fall prevention device / auxiliary ladder for the main lid, the fall prevention device / auxiliary ladder for the child lid, and the outer peripheral safety auxiliary device can be easily removed.

マンホールの蓋用フック留め金具にフック留め金具側落下防止装置受け金物を取り付けし、前記マンホールのタラップにタラップ側落下防止装置を取り付けし、前記フック留め金具側落下防止装置と前記タラップ側落下防止装置に親蓋用落下防止装置兼補助梯子、子蓋用落下防止装置兼補助梯子と外周安全補助装置を取り付け出来る事を特徴とします。 A hook clamp side fall prevention device receiving metal fitting is attached to a hook fastener for a manhole cover, a trap side fall prevention device is attached to the manhole lap, and the hook clamp side fall prevention device and the trap side fall prevention device are attached. It is characterized in that it can be attached with a fall prevention device / auxiliary ladder for the main lid, a fall prevention device / auxiliary ladder for the child lid and an outer peripheral safety auxiliary device.

前記マンホールの子蓋が開いた時、前記子蓋用落下防止装置兼補助梯子が、有効となり、前記子蓋用落下防止装置兼補助梯子を引き起こして、梯子として使用し、前記マンホールの親蓋が開いた時、前記子蓋用落下防止装置兼補助梯子と前記親蓋用落下防止装置兼補助梯子が、有効となり、前記子蓋用落下防止装置兼補助梯子か前記親蓋用落下防止装置兼補助梯子の何れかを引き起こして、梯子として使用出来る事を特徴とします。 When the manhole cover is opened, the child lid fall prevention device and auxiliary ladder are activated, causing the child lid fall prevention device and auxiliary ladder to be used as a ladder, and the manhole cover is When opened, the child lid fall prevention device / auxiliary ladder and the parent lid fall prevention device / auxiliary ladder become effective, and the child lid fall prevention device / auxiliary ladder or the parent lid fall prevention device / auxiliary It can be used as a ladder by causing any of the ladders.

親蓋を開いた時の恐怖感が消え、安心して作業が出来るようになる。作業の状況で邪魔になる時は、外し、必要な時に取り付けて、作業を安全に進めるように出来る。 The fear of opening the lid disappears and you can work with peace of mind. If it gets in the way of your work, you can remove it and attach it when you need it to keep it safe.
