性があった。The groove lid holding portion of the above-mentioned groove lid lifting machine is often used because it has a rhombic structure so that an operator can attach and detach the groove lid with a light force. When the groove lid is lifted and the groove lid is sandwiched, a force of 2 g is applied to the pivots of the two support plates as shown in FIG. 4 (a), and there is a thickness d of the support plates, and the twist shown in FIG. Force (F
1, F2) occurs, and this twisting force tries to rotate the groove lid when the groove lid is lifted, and therefore, when used for a long time, metal fatigue occurs in the support plate and the groove lid may fall off. There was a nature.

The distance c between the central portions of 3 is about 17 mm, and the mounting angle between the central portions of the upper support plates 13 and 23 and the sandwiching plates 11 and 21 is preferably about 60 °.
【００２７】以上本発明の実施例について説明したが、
本発明はこのような実施例に何等限定されるものでな
く、本発明の要旨を逸脱しない範囲において種々なる態
様で実施し得ることはもちろんである。The embodiment of the present invention has been described above.
The present invention is not limited to such embodiments, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the present invention.
【００２８】[0028]
【発明の効果】本発明に係る溝蓋着脱機を使用すると、
一方の支持板の中間部に保持枠を設けてあるので支持板
が互いに交差しない構造なので、溝蓋を持ち上げた時
に、ねじり力が発生しないために、溝蓋を回転させよう
とする力が生じないので、脱落の危険性がなくなり、安
全に作業ができるようになった。When the groove lid attaching / detaching machine according to the present invention is used,
Since the support frame is provided in the middle part of one of the support plates, the support plates do not intersect with each other.Therefore, when the groove lid is lifted, no twisting force is generated, so there is a force to rotate the groove lid. Since there is no such thing, there is no danger of falling off and it is now possible to work safely.
【００２９】また、挟持板近くの係合孔を支点とするこ
とにより、梃子の支点が２箇所になり、強力な挟持力を
発生させ、溝蓋を保持する構造なので、溝蓋の脱落する
危険性がなくなり、安全に作業ができるようになった。Further, by using the engaging hole near the sandwiching plate as the fulcrum, the fulcrum of the lever is at two points, and a strong clamping force is generated to hold the groove lid. I lost my ability to work safely.
【００３０】さらに、図３（ロ）で支持板の中心より係
合孔の中心が寸法ｃだけ下方に下げることで、２枚の挟
持板の開きが大きくなり、溝蓋の着脱がスムーズにでき
るようになった。Further, by lowering the center of the engaging hole by a dimension c from the center of the support plate in FIG. 3B, the opening of the two holding plates becomes large and the groove lid can be attached and detached smoothly. It became so.
