The invention discloses a road manhole cover lifting device for a municipal road. The road manhole cover lifting device for the municipal road comprises a supporting cross plate; a round hoisting plate parallel with the supporting cross plate is arranged on the lower side of the supporting cross plate; the two ends of the round hoisting plate are each provided with a sliding sleeve; a screw lead shaft connected with each sliding sleeve in a threaded cooperation manner penetrates the interior of the sliding sleeve; two hoisting rods are arranged on the round hoisting plate; a rotating knob is arranged at the top end of each hoisting rod; a cover lifting rod perpendicular to each hoisting rod is arranged at the bottom end of the hoisting rod; a plurality of lifting devices arranged annularlyare further arranged at the lower end of the round hoisting plate; each lifting device comprises a barrel body and an arc-shaped top plate with the upper end stretching into the barrel body; the upper ends of the arc-shaped top plates are connected with the interiors of the barrel bodies through compression springs; a baffle is arranged on the lower end edge of the round hoisting plate; and the baffle is connected with the side walls of the barrel bodies through ejecting and pressing springs. The road manhole cover lifting device for the municipal road is simple in structure, the cover lifting efficiency is high, cover lifting is stable, movement is convenient, operation is easy and convenient, the manual labor is low, and practicability is high.
Description
technical field [0001] The invention relates to municipal construction equipment, in particular to a device for lifting manhole covers for municipal roads. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. Municipal engineering is an important part of urban sewage treatment. Sewage pipes will be inspected and maintained regularly. In case of pipe blockage, the sewage manhole cover needs to be opened in time for cleaning. At present, it is all manually using a crowbar to pass through the existing [0003] If the holes on the two sewage manhole covers are pried open, the labor intensity is relatively large, the work efficiency...
