A municipal square manhole cover lifting device with adjustable width

Abstract

The invention discloses a municipal square manhole cover lifting device with adjustable width, which relates to the technical field of manhole cover lifting. The purpose of the invention is to provide an adjustable width that can improve the removal efficiency of square manhole covers and is suitable for removing square manhole covers of various specifications. The municipal square manhole cover lifting device. A municipal square manhole cover lifting device with adjustable width, including a mounting frame, a support frame, an electric push rod, a lifting mechanism, etc.; the support frame is fixedly installed on the mounting frame, the electric push rod is fixedly mounted on the support frame, and the lifting mechanism It is installed at one end of the electric push rod, and the clamping mechanism is installed at one side of the lifting mechanism. The present invention can make the clamping frame and the clamping rod drop from the square hole of the square well cover to the bottom of the square well cover by setting the lifting mechanism, the clamping mechanism and the rotary discharging mechanism, and then rotate and rise to clamp the square well cover in the clamping position. Lift on the rod to realize the lifting of the square manhole cover.

Description

technical field [0001] The invention relates to the technical field of manhole cover lifting, in particular to a municipal square manhole cover lifting device with adjustable width. Background technique [0002] The manhole cover is a road covering used to cover the road, which can prevent people or objects from falling. The manhole cover is mainly divided into two shapes, among which the square manhole cover is a main form of manhole cover. On urban roads, it can speed up the entry of rainwater and other liquids and prevent roads from stagnant water. [0003] The square manhole cover is the infrastructure of municipal engineering, and it is also a facility that needs to be moved frequently in the construction of municipal engineering. In real life, the square manhole cover must be removed in the face of road reconstruction, sewer construction, manhole cover damage, and manhole cover looseness. The removal of manhole covers is mainly carried out manually by construction per...
