Abstract

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.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a reversible manhole cover lifting device for municipal engineering construction. Background technique [0002] Manhole covers are one of the most inconspicuous but most indispensable infrastructures on public roads. They are used to cover deep road wells and prevent pedestrians from falling. They can be made of reinforced concrete, stainless steel and other materials. At present, most common manhole covers are square and round. , There are generally two or more through holes or handles on the edge of the manhole cover, which is convenient to open and close. Because the manhole cover has a strong load-bearing capacity, its own quality is also relatively heavy. When opening the manhole cover, construction personnel often use crowbars, etc. Simple tools are lifted manually. On the one hand, it is not convenient to move to a fixed place after lifting, and it needs to b...
