The invention relates to the technical field of invisible well lid opening, and particularly discloses a portable invisible well lid opening device, an opening method and a mounting method. The device comprises a moving part, a manual lifting part, an H-shaped lifting frame and a foldable main body lifting frame, in the main body hoisting frame, the manual hoisting part is connected with a top frame ring of the main body hoisting frame; the manual lifting component is connected with the symmetrical midpoint of the H-shaped lifting frame through a first chain-shaped connecting piece of the manual lifting component; the H-shaped lifting frame is connected with a lifting hole of a to-be-opened invisible well lid in a clamped mode through a plurality of second chain-shaped connecting pieces of the H-shaped lifting frame. And the moving part is movably connected with the bottom of the main body hoisting frame. When an invisible well lid is opened, a hand chain block is driven by dragging a manual chain, then a second iron chain drives an H-shaped lifting frame to have a lifting function, the opening effect can be achieved at the moment, the device is easy to manufacture and convenient and fast to operate, the invisible well lid can be easily opened, and personnel investment is reduced.

    本发明涉及隐形井盖开启技术领域,具体公开了一种便携式隐形井盖开启装置、开启方法及安装方法;装置包括:移动部件、手动起重部件、H型起吊架以及可折叠的主体起吊架;在主体起吊架内部:手动起重部件与主体起吊架的顶架环连接;手动起重部件通过自带的第一链型连接件与H型起吊架的对称中点连接;所述H型起吊架通过自带的多个第二链型连接件与待开启隐形井盖的提拉孔卡接;所述移动部件与主体起吊架底部活动连接。本发明在对隐形井盖开启时,只需通过拖动手动链条使手拉葫芦进行传动,进而使得第二铁链带动H型起吊架具有升降的功能,这时便可实现开启的作用,该装置制作简单,操作便捷,能够轻松开启隐形井盖,减少人员投入。
