Abstract

The invention discloses a loosening device for an underground well lid of a municipal road. The loosening device comprises a main body shell. According to the loosening device, a gear and worm principle is utilized, and the underground well lid can be cyclically and effectively loosened so that the underground well lid can be opened under the condition that the damage degree is low; moreover, thedevice is provided with a certain mechanical protection mechanism so that the well lid can be effectively protected in the working process on the premise of independence, and the phenomenon that the well lid is damaged due to excessive looseness is prevented; furthermore, the device is provided with an annular array spring compression abutting type rotation force control mechanism so that the maximum force during rotation can be controlled, and the phenomenon that a driving motor is damaged due to excessive rotation resistance is prevented; and in addition the device is provided with a reversethread structure rotary longitudinal height adjusting mechanism so that the tension degree between components can be adjusted, and then the device can effectively improve the working efficiency.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a loosening device for underground manhole covers of municipal roads. Background technique [0002] At present, on the highway, in order to keep the road from being submerged by water, underground water channels will be set up, so manhole covers will be used.
