Manhole cover disassembly and assembly device for municipal engineering

Abstract

The invention discloses a manhole cover disassembly and assembly device for municipal engineering. The manhole cover disassembly and assembly device comprises a base, wherein universal wheels are arranged at the four corners of the bottom of the base; a first left electric push rod and a first right electric push rod are fixedly arranged on the top of the base; the top push rods of the first electric push rods are fixedly connected to a lifting plate; a left supporting plate and a right supporting plate are fixedly arranged on the top of the lifting plate; a guide rail is fixedly connected between the left supporting plate and the right supporting plate; a left cover lifting plate and a right cover lifting plate are also arranged between the left supporting plate and the right supporting plate; the guide rail passes through the cover lifting plates and is connected to the cover lifting plates in a sliding manner; a threaded rod is also arranged between the left supporting plate and theright supporting plate; the right handed thread and left handed thread of the threaded rod respectively pass through the left cover lifting plate and the right cover lifting plate and are in threadedconnection with the left cover lifting plate and the right cover lifting plate; the bottom of each cover lifting plate is split into a left elastic plate and a right elastic plate from bottom to top;and the bottom of each elastic plate is fixedly connected to a cover lifting inverted triangle block. According to the manhole cover disassembly and assembly device, the electric push rods are controlled to shorten, so that the cover lifting inverted triangle blocks pass cover lifting holes, then the first push rods are controlled to elongate so as to lift a manhole cover; and the manhole cover does not need to be manually carried, and thus, the physical strength is saved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering machinery, in particular to a well cover dismounting device for municipal engineering. Background technique [0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. They are generally round and can be used for green belts, sidewalks, motorways, Piers, alleys, etc. [0003] Municipal engineering is an important part of urban sewage treatment. Sewage pipes will be inspected and maintained regularly. In case of pipeline blockage, the manhole cover needs to be opened in time for cleaning. When the manhole cover is damaged, it also needs to be replaced. At present, the manhole cover is generally disassembled and assembled manually. Use the hook to stretch into the lid lifting hole on...

Problems solved by technology

[0003] Municipal engineering is an important part of urban sewage treatment. The sewage pipeline will be inspected and maintained regularly. When the pipeline is blocked, the manhole cover needs to be opened in time for cleaning. Use the hook to extend into the cover hole on the manhole cover to lift the manhole cover upwards, the labor intensity is relatively high, and the work efficiency is relatively low
