An anti-fall manhole cover assembly

Abstract

The invention discloses an anti-falling inspection well cover assembly which comprises a well platform, a cover, a support layer and an anti-falling net. A groove which is matched with the cover is formed in the well platform, the support layer is arranged at the bottom of the groove, a gravity compressing rubber ring is arranged at the upper edge of the support layer, a plurality of check blocks are arranged at the bottom of the well platform and are equidistantly arranged on the inner wall of the well platform, and the anti-falling net is mounted above the check blocks and is matched with the inner diameter of the well platform; the cover is of an inverted trapezoid structure, a protrusion is arranged in the center of the lower portion of the cover, and an extension portion is arranged on a side surface of the cover. The anti-falling inspection well cover assembly has the advantages that the anti-falling net is arranged in the well platform, so that falling accidents can be prevented when the cover moves out; hook rings which can be retreated into countersunk grooves are arranged on the top surface of the cover, so that the cover is convenient to mount and move out; the extension portion arranged on the side surface of the cover and a positioning groove formed in the well platform are fittingly mounted, so that the cover can be firmly mounted, and can be prevented from being separated from the anti-falling inspection well cover assembly when being impacted, and the stability of the anti-falling inspection well cover assembly can be improved.

Description

technical field [0001] The invention relates to the field of municipal facilities, in particular to an anti-fall inspection shaft cover assembly. Background technique [0002] Inspection manhole covers can be seen everywhere in the streets and alleys of cities and towns. Passers-by almost turn a blind eye to them, and almost no one stops for them. At present, the existing inspection manhole covers are not easy to install, and the structure is complicated and the practicability is poor. Due to the lack of municipal inspection manhole covers The accidents of personal casualties caused and the theft of power facilities and blackout accidents occur frequently. In addition, because the positioning of the existing manhole cover is not firm enough, the vehicle is prone to displacement after rolling, causing the vehicle to fall into the mouth of the manhole and cause damage. Contents of the invention [0003] The object of the present invention is to provide an anti-fall manhole c...
