The invention provides a well opening tool and relates to the field of maintenance equipment, the well opening tool comprises a supporting mechanism, the supporting mechanism comprises a main beam and two supporting units, each supporting unit comprises two supporting legs, and the two supporting legs are rotatably matched with the main beam so as to be switched between an unfolding position and a folding position. The supporting legs can be switched between the unfolding position and the folding position, when the supporting legs are located at the folding position, the supporting legs make close contact with the main beam, the overall structure is compact, the size is small, the occupied space is small, and storage and conveying are convenient. Meanwhile, when the manhole cover opening device needs to be used, the supporting legs are adjusted to be unfolded positions, the main beam is supported through the supporting legs and located above the manhole cover to be opened, the manhole cover is hoisted through the hoisting mechanism, time and labor are saved during construction, the manhole cover is convenient and rapid to disassemble, and the construction efficiency is high.

    本申请提供一种开井工装,涉及检修设备领域,开井工装包括支撑机构,支撑机构包括主梁和两个支撑单元,每组支撑单元均包括两个支撑腿,两个支撑腿均与主梁可转动地配合,以在展开位置和折叠位置之间切换。支撑腿能够在展开位置和折叠位置之间切换,当处于折叠位置时,支撑腿与主梁紧密接触,整体结构紧凑,体积小,占用的空间小,便于收纳和输送。同时,需要使用时,将支撑腿调整为展开位置,依靠支撑腿将主梁支撑起来,并且使主梁位于待打开的井盖的上方,利用吊装机构将井盖吊起即可,施工省时省力,井盖拆卸方便快捷,施工效率高。
