According to a reversing type well lid lifting device for municipal engineering construction, bottom plates are arranged to be an upper bottom plate and a lower bottom plate which can rotate relatively, damping wheels are arranged on the lower bottom plate, when the whole device moves to the upper portion of a well lid, positioning of the lower bottom plate and the ground is achieved through positioning pins inserted into the side portion of the lower bottom plate, and the whole device is prevented from moving relative to the ground; and at the moment, if a hanging buckle structure and the well lid need to be adjusted, the mounting frame on the upper portion of the upper bottom plate rotates along with the upper bottom plate by rotating the upper bottom plate, so that the shortest distance between the hanging buckle structure and the well lid can be found conveniently.
一种市政工程施工用换向式井盖提起装置,通过将底板设置成为可相对转动的上底板与下底板,减震轮设置在下底板上,在装置整体移动至井盖上部时,通过插入下底板侧部的定位销,实现下底板与地面的定位,防止装置整体相对地面移动,此时若需要对挂扣结构与井盖间进行调整时,通过转动上底板,上底板上部的安装架一同跟随转动,以便于寻找挂扣结构与井盖间连接的最短距离。
