The invention discloses a municipal inspection well cover levering device. The municipal inspection well cover levering device comprises a rack, a hydraulic jack, a hydraulic driving cylinder and a levering rod; the hydraulic jack is fixed to the middle position of the bottom of the side face of the rack; a connection rod is fixedly connected to the upper end of the hydraulic jack; a connection ring is fixedly connected to the upper end of the connection rod; a connection chain is fixedly connected to the upper end of the connection ring, and is fixedly connected to the surface of the leveringrod in a sleeving manner; a levering head is welded to the top end position of the levering rod; the hydraulic driving cylinder is installed at the middle position of the bottom of the side face, deviating from the hydraulic jack, of the rack, and is provided with a hydraulic sleeving rod; the hydraulic sleeving rod and the levering rod are arranged in different planes; and a hydraulic sliding rod is installed in the hydraulic sleeving rod in a sliding manner. By means of the municipal inspection well cover levering device, an inspection well cover can be easily levered up, and the workload of construction workers is substantially relieved.
Description
technical field [0001] The invention relates to the technical field of municipal maintenance equipment, in particular to a prying device for municipal inspection shaft covers. Background technique [0002] Manhole cover means that there will be a lot of underground pipelines in urban construction, such as sewers, underground gas pipelines, tap water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section, from the pipeline to the ground. This section on the ground is called the inspection well, and the mouth of the inspection well is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. [0003] The inspection well cover mainly plays the role of protection and isolation. Since the above-mentioned pipelines often need to be dredged or repaired, it is necessary to pry up the inspection well cover at t...
