Hand-operated type simple lid lifting device of well lid

Abstract

The invention discloses a hand-operated type simple lid lifting device of a well lid. The hand-operated type simple lid lifting device comprises a supporting transverse plate, wherein the two sides ofthe lower end surface of the supporting transverse plate are equipped with supporting vertical plates; a lid lifting transverse shaft which is parallel to the supporting transverse plate is arrangedabove the supporting transverse plate; the two ends of the lid lifting transverse shaft are mounted on the supporting transverse plate through rotary bases; two rolling-up wheels are arranged on the lid lifting transverse shaft; steel wire lifting ropes are wound on the rolling-up wheels; the lower ends of the two steel wire lifting ropes pass through the supporting transverse plate, and are connected with the upper end surface of a lifting plate; one end of the lid lifting transverse shaft is fixedly connected with a pulling circular disc; the position, on the outer side wall of the inner part of a square guide tube, of a rotary vertical shaft is equipped with a spiral section; a regulating drive sleeve which is matched with the spiral section is in sleeve connection on the outer side ofthe rotary vertical shaft; the regulating drive sleeve is in up-down sliding connection with the inner wall of the square guide tube; and four pairs of connecting rods are arranged at the outer side of the square guide tube. The device is simple in structure, is labor-saving in lid lifting, is simple and convenient to operate, is relatively high in well lifting efficiency, is relatively low in cost, and is relatively high in practicability.

Description

technical field [0001] The invention relates to the technical field of pavement cover removal, in particular to a manual and simple manhole cover removal device. 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, the crowbar is manually used to pry open through the holes on the existing two sewage well covers. The labor intensity is relatively high, the work efficiency is relatively low, and the well...

AI Technical Summary

Problems solved by technology

At present, a pry is used manually to pry open through the holes on the existing two sewage manhole covers. The labor intensity is relatively high, the work efficiency is relatively low, and the manhole cover is easily damaged, resulting in a short service life of the manhole cover.
