Abstract

The invention discloses an auxiliary device for opening a working well lid. The auxiliary device comprises a rack, wherein a mounting table driven by a first power plant is vertically mounted on the rack in a sliding manner; a rotary disc driven by a second power plant rotates on the mounting table; a dust loosening mechanism is mounted above the rotary disc in a sliding manner, is distributed onthe circumference of the rotary disc and extends downwards; a dust cleaning mechanism is arranged on the dust loosening mechanism; and a well lid shaking mechanism driven by a third power plant is arranged below the mounting table. Compared with traditional manual opening, the auxiliary device greatly lowers the labor strength of working staff and the well lid opening difficulty, costs less time,is high in well lid opening efficiency, ensures fast repairing and maintenance and normal electric power supply of a power grid system, does not cause any damage to the well lid body, ensures the service life of the well lid, and is convenient in operation, excellent in using effect and high in practicality.

Description

technical field [0001] The invention belongs to the technical field of manhole cover opening aids, and in particular relates to an auxiliary device for opening manhole covers. Background technique [0002] Cables are generally laid in underground cable trenches. Because each cable is only a certain length, about several hundred meters, in order to lay longer cable lines, multiple cables must be connected. A certain space is required for making and placing cable joints. This space is called It is a cable well, and its width and depth are generally greater than that of the cable trench. A well cover for covering the wellhead of the well is placed on the ground, and the upper surface of the well cover is basically flush with the ground. The structure of the manhole cover is a circular disc made of concrete, and there is a steel mesh inside to ensure the structural strength in long-term use. There is also at least one groove on the upper surface of the manhole cover, which does ...
