安全帯のロープを電線に回して電線上を乗り出し
て行くのであるが、この時に作業者が手足を滑ら
せて宙吊りの状態になつた場合、送電線鉄塔側は
必ず下り勾配になつているため作業者の装着した
安全帯のロープが電線上を滑つて行き送電線鉄塔
間の中央まで滑つて行つたり或いは滑つて行く間
にロープがすり切れて墜落して重大事故につなが
ることがあつた。 Conventionally, during come-along installation work during power line tension work, or during maintenance inspection work after completion,
The rope of the safety belt is wrapped around the power line and the worker climbs over the power line, but if the worker slips and becomes suspended in the air, the power line tower side is always on a downward slope. There have been cases where the safety belt rope worn by the worker has slipped on the power lines and slid down to the center between the transmission line towers, or while slipping, the rope has worn out and caused the worker to fall, leading to a serious accident. .
そこで本案は上記の作業時に使用する安全器で
軽量で、送電線に容易に嵌合でき、非常時には確
実に停止し、しかも送電線を傷めない安全器を提
供することをその目的とするものである。 Therefore, the purpose of this proposal is to provide a safety device for use during the above-mentioned work that is lightweight, can be easily fitted to the power transmission line, will stop reliably in an emergency, and will not damage the power transmission line. be.

るものである。 As shown in the figure, in this embodiment, a frame body 1 and receivers 2, 2 provided with sliding rollers 21, 21 are connected by a hinge 1 on one side.
2 and a rotating link 5 which is detachably latched on the other side to form a power transmission line insertion holder 3 which can be opened and closed, and a power transmission line pressing member 4 made of synthetic resin and having a recessed part in the center is fixed to one end. . It has a structure in which the connecting fittings 7, 7 are connected by a wire rope as a connecting member 8.

全帯のＤ環に嵌合する。そしてカムアロング１０
の本体を電線にかぶせ滑らせながら所定の位置ま
で宙乗りしていくのである。 The method of using this invention is explained using the usage state diagram when installing the come-along in Fig. 5. First, the operator climbs on the extended electric wire, pulls the receivers 2 and 2 of the safety device of this invention in opposite directions, The hinges 12 and 12 are then rotated in opposite directions using the hinges 12 and 12 as fulcrums to open and engage the power transmission line, and the hook 91 of the lifeline 9 provided on the wire rope 8 is attached to the D ring of the safety belt worn by the worker. Fit together. And come along 10
The main body of the electric wire is placed over the wire and the electric wire is slid until it reaches a certain position.
本案は上記の様に使用するもので簡単な操作で
容易に着脱ができ、作業者が墜落した場合は連結
金具７，７が急激に引かれると同時に２本の回動
リンク５，６の送電線押圧部材４が送電線側へ押
圧してその移動を確実に停止する。 This method is used as described above and can be easily attached and detached with a simple operation.If a worker falls, the connecting fittings 7, 7 are suddenly pulled and at the same time the two rotating links 5, 6 are moved. The wire pressing member 4 presses toward the power transmission line and reliably stops its movement.
２本の回動リンク５，６は各々逆方向に向いて
いるので左右いずれの方向へ移動中でもその停止
作用は確実に行い、墜落した場合でも合成樹脂製
の押圧部材４を使用しているため送電線にキズを
付けずに押圧し、傾斜方向へ移動することはな
い。 Since the two rotation links 5 and 6 face in opposite directions, the stopping action is ensured even when moving in either the left or right direction, and even in the event of a fall, the synthetic resin pressing member 4 is used. It presses on power lines without damaging them and does not move in an inclined direction.
又摺動ローラ２１，２１を受体２，２の両端部
に設けているので本安全器の動きは安定し、不用
意に回動リンク５，６が回動して押圧部材４が送
電線を押圧することはない。又移動方向が変るご
とに本器を取り替える必要はない。 In addition, since the sliding rollers 21, 21 are provided at both ends of the receivers 2, 2, the movement of this safety device is stable, and if the rotating links 5, 6 are inadvertently rotated, the pressing member 4 may be damaged by the power transmission line. There will be no pressure on you. Also, there is no need to replace the device every time the direction of movement changes.
上記したことはカムアロング取付作業時の使用
のみでなく、送電線工事の完成後保守点検作業等
で宙乗器に乗つて送電線を点検して行く場合も同
じで、作業者が宙乗器より手足を滑らせて墜落し
ても本器を取付けておけば上記の様に確実に墜落
を防止できると共に、本器を取付けることにより
作業者に安心感を与え作業能率が向上する効果が
ある。 The above applies not only to the use during come-along installation work, but also when inspecting power transmission lines while riding on the air ride for maintenance and inspection work after the completion of power transmission line work. Even if a worker slips and falls, having this device installed will reliably prevent a fall as described above, as well as providing a sense of security to the worker and improving work efficiency.
