DEVICE FOE PREVENTING FALLING IN PIPE
To provide a device for preventing falling in a pipe that can move smoothly inside a pipe line that consists of multiple pipe bodies and is arranged at an angle, can be easily and securely fixed at a desired position, and has excellent safety to prevent workers working inside the pipe line and an apparatus, etc., used inside the pipe line from falling downstream in the pipe line.SOLUTION: A device 10 for preventing falling in a pipe comprises: a main frame 12; a plurality of moving wheels 14 arranged on an outside circumference of the main frame 12 in the radial direction and touching an inner peripheral surface 13 of a pipe line 11; a plurality of stopper sections 15 radially attached to the main frame 12 and having a tip side protruding outside the main frame 12 in the radial direction and touching the inner peripheral surface 13 of the pipe line 11; a cover section 16 attached to the front side of the main frame 12 that is the upstream side of the pipe line 11 when in use; and a plurality of connectors 19 attached to the front side of the main frame 12, and to which the other end of a connecting material for suspension and movement, one end of which is connected to the upstream side of the pipe line 11, is connected.SELECTED DRAWING: Figure 1
【課題】複数の管体で構成され傾斜して配置される管路の内部をスムーズに移動することができ、所望の位置に簡単かつ確実に固定可能で、管路の内部で作業する作業者及び管路の内部で使用される機材等が管路の下流側に落下することを防止する安全性に優れた管内落下防止装置を提供する。【解決手段】管内落下防止装置１０は、本体フレーム１２と、本体フレーム１２の半径方向外側の円周上に配置され管路１１の内周面１３に接地する複数の移動輪１４と、本体フレーム１２に放射状に取付けられ、先側が本体フレーム１２の半径方向外側に突出して管路１１の内周面１３に当接する複数のストッパー部１５と、使用時に管路１１の上流側となる本体フレーム１２の正面側に取付けられたカバー部１６と、本体フレーム１２の正面側に取付けられ、一端側が管路１１の上流側に連結される吊り下げ兼移動用連結材の他端側が連結される複数の連結具１９とを備える。【選択図】図１
