Manhole cover replacing machine

Abstract

The invention discloses a manhole cover replacing machine. The machine is used for replacing an inspection manhole cover in a road surface and comprises a machine frame; the machine frame comprises two or more hollow upright columns, wherein a movable mounting platform is arranged between the upright columns, a cutter head assembly for rotationally cutting the operation surface is arranged right below the mounting platform, and a bursting and clamping mechanism for bursting a manhole body masonry material and clamping a manhole seat is arranged right below the cutter head assembly; and a firstdriving mechanism for enabling the mounting platform to reciprocate in a vertical direction is arranged at the top end of any upright column, and a second driving mechanism for enabling the cutter head assembly to rotate along a central axis is arranged on the mounting platform. According to the manhole cover replacing machine, the milling and planing of the road surface, the lifting and pullingof the manhole seat and the loading of the manhole cover can be completed at one time, and the problems of insufficient power and rigidity and the like of existing equipment during the operation on the cement road surface with hard texture are solved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering devices, in particular to a manhole cover replacement machine. Background technique [0002] Inspection manhole covers are common ground facilities such as municipal roads, green belts, and docks. They are used to cover the maintenance entrances of urban livelihood facilities such as underground water pipes and optical cables. In the case of checking the aging or damage of the manhole cover, it is necessary to replace the new manhole cover in time to avoid greater safety hazards to passing pedestrians and vehicles. [0003] At present, most of the manhole cover replacement operations still use manual prying out of the old manhole cover, and then replace the new manhole cover. The old manhole cover may be corroded for a long time, and it is difficult to replace it. There is the risk of being smashed in the process of replacing the well cover, so there is an urgent need for a well cov...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a manhole cover replacement machine, which can be applied to the manhole cover replacement operation of various road surfaces such as asphalt and concrete, and can complete the milling of the road surface, the well seat lifting, and the manhole cover at one time. The formation of the installation surface and the loading operation of the manhole cover are aimed at solving the problems of insufficient cutting depth, easy damage of the cutter head, and insufficient power and rigidity when operating on the hard mud road surface of the existing manhole cover replacement equipment.
