Abstract
This utility model relates to the field of manhole cover installation in municipal engineering, specifically an auxiliary device for manhole cover installation in municipal engineering. It includes a mounting frame, a fixed frame fixedly connected to the top of the mounting frame, a moving mechanism on the top of the mounting frame, and a support mechanism at the bottom of the fixed frame. This utility model uses a small cylinder to move a hollow sleeve rod, which in turn moves an arc-shaped block and a support block via a rotating plate. This allows the support block to cooperate with the arc-shaped block to support and lift the manhole cover, reducing swaying after lifting. Simultaneously, the rotation of the rotating plate drives the moving block to rotate, moving the hollow plate and the fixed rod, and the rotation of the threaded rod further moves the fixed rod, allowing for fine-tuning of the fixed rod on the Y and X axes, thus facilitating precise adjustment of the manhole cover's position by workers.
