OPENING/CLOSING MOVING DEVICE OF MANHOLE COVER
To reasonably lift and move a manhole cover blocking an opening of a common conduit, a manhole and or the like from the opening.SOLUTION: An opening/closing moving device of a manhole cover is composed of: a moving base 1 that connects left and right base frames 2 arranged on both sides of a manhole cover M with front and rear connection bars 9 and can make the base frames movable by moving wheels 5; lifting mechanisms 10 that are provided the left and right base frames 2 in raised states; suspension bars 15 that are installed between the lifting mechanisms 10 and are lifted up/down by a lifting operation of the lifting mechanisms 10; and suspension tools 20 that are connected to the suspension bars 15, are fit into engagement holes P opened in the manhole cover M, and are engaged with hole edges of the engagement holes P. The suspension tool 20 includes a suspension tool body 21 having an engagement end 22 and a rotation stopper 23, engages an engagement end 22 with the engagement hole P by rotation by almost 90 degrees after insertion of the suspension tool body 21 into the engagement hole P, and prevents rotation and extraction of the suspension tool body 21 by fitting of the rotation stopper 23.SELECTED DRAWING: Figure 1
【課題】共同溝、マンホール等の開口部を閉塞しているマンホール蓋を開口部から無理なく持ち上げ、また移動できるようにする。【解決手段】マンホール蓋Ｍの両脇に配置する左右のベースフレーム２を前後の連結バー９によって連結すると共に、移動車輪５によって移動可能にした移動ベース１と、左右のベースフレーム２それぞれに立脚状に設けた昇降機構１０と、この昇降機構１０相互間に架装されていて、昇降機構１０による昇降操作で昇降する吊下バー１５と、吊下バー１５に連繋して、マンホール蓋Ｍに開穿の係止孔Ｐに嵌め入れて係止孔Ｐの孔縁に係止する吊具２０とから成る。吊具２０は、係止端２２を有する吊具本体２１、回転ストッパー２３を備え、吊具本体２１の係止孔Ｐ内への挿入後のほぼ９０度回転で係止端２２を係止孔Ｐに係止させ、回転ストッパー２３の嵌め入れで吊具本体２１の回転・抜去を阻止する。【選択図】図１
