Problems solved by technology

[0002] There are certain disadvantages in the lifting holes of existing old manhole covers on urban sidewalks: 1) Opening holes in the manhole covers: The lifting holes of old manhole covers are generally opened on the manhole cover or welded on the frame of the manhole cover. It is easy to drop garbage and dirt, and it is easy to open holes and crack after a long time of use; 2) It affects the appearance of the pavement: the sidewalk environment of urban roads is the most intuitive reflection of the city's appearance, and the lifting holes of the old manhole cover do not match the pavement effect of the sidewalk

Abstract

The invention relates to the field of municipal engineering, in particular to a manhole cover lifting device comprising a lifting plug and a cylindrical storage sleeve. The bottom end of the storage sleeve is fixedly connected to a manhole cover baseplate, and the inside wall of the top end of the storage sleeve is provided with a blocking part; the lifting plug is movably imbedded in the storagesleeve, and the side wall of the lifting plug is provided with a lifting through hole formed vertically to the axis of the lifting plug; and the outside wall of one end, opposite to the manhole coverbaseplate, of the lifting plug is provided with a limit part. According to the manhole cover lifting device provided by the invention, the manhole cover baseplate is provided with the storage sleeve,and the lifting plug is embedded in the storage sleeve in a liftable manner; the lifting plug is concealed in the storage sleeve in the daily state, so that the beautiful appearance of a pavement is not affected; when the manhole cover is lifted, the lifting plug can extend out of the storage sleeve, and the lifting through hole on the lifting plug facilitates construction personnel to lift up themanhole cover.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a well cover lifting device. Background technique [0002] There are certain disadvantages in the lifting holes of existing old manhole covers on urban sidewalks: 1) Opening holes in the manhole covers: The lifting holes of old manhole covers are generally opened on the manhole cover or welded on the frame of the manhole cover. It is easy to drop garbage and dirt, and it is easy to open holes and crack after long-term use; 2) Affect the pavement appearance: the sidewalk environment of urban roads is the most intuitive reflection of the city's appearance, and the lifting holes of old manhole covers do not match the pavement effect of sidewalks. Contents of the invention [0003] The purpose of the present invention is to provide a manhole cover lifting device, the lifting plug is hidden in the storage sleeve when not in use, which does not affect the appearance of the road s...
