Abstract
The invention discloses a municipal manhole cover which comprises a barrel, a flange plate, a cover body and a hinge seat. The flange plate is arranged at the bottom of the barrel. An outwards-convex reinforcing rib is arranged in the middle of the barrel. A rubber gasket is mounted at the bottom of the flange plate. The cover body is arranged on the barrel. The hinge seat is mounted on the inner side of the cover body. A rotating shaft is arranged in the hinge seat. A limiting rod is welded to the middle of the rotating shaft. Reinforcing ribs distributed in a cross manner are further arranged on the inner side of the cover body. Water permeable holes are formed in the cover body. Hooks and a support are welded in the barrel. A protection net is arranged on the hooks. The limiting rod penetrates the support. A check block is welded to the bottom of the limiting rod. The municipal manhole cover has a buffer function, is high in structural strength and safety performance and meanwhile can achieve burglary prevention.
Description
Technical field
The present invention relates to a kind of municipal well lid.
Background technology
Well lid is used to cover road or family's middle-deep well, prevents people or object from falling.Tongzhou six directions casting can be divided by material
For metal well lid, high strength fibre cement concrete well lid, Resin man-hole cover etc..It is general to adopt circular.Can be used for greenbelt, people's row
Road, car lane, harbour, lane etc..There are many kinds, individual layer, double-deck, cast iron, spheroidal graphite in the national standard of Chinese well lid
Cast iron, compound, cement, magnesite etc..Well lid weight bearing power is referred to, in unit area, carries out pressure by pressure testing machine
Test, it is generally heavy 40 tons.And if by if car, 5 axle heavy load truck computing formula：5 axle x40 ton=200 ton.In vapour
Under car gross weight 200T tonnage, the heavy well cover can ensure that and pass through.A lot of underground pipings are had in urban construction, than following water
Road, underground gas pipeline, water supply pipe, power pipe, communication conduit, national defence pipeline etc., these pipelines will have every one section
One outlet for leading to ground, is referred to as inspection shaft by this section of pipeline to ground, and catch pit port is generally concordant with ground, it is therefore desirable to
One lid, for the lid of lid inspection shaft, is inspection well cover.Inspection well cover is generally with material systems such as reinforced concrete, metal, reinforced plastics
Into shape is based on circular and square.
Existing well lid does not have pooling feature at present, and structural strength is not high, and security performance is not high, it is impossible to enough antitheft.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind and has pooling feature, and structural strength is high, and security performance is high, together
When can also be antitheft municipal well lid.
To solve the above problems, the present invention is adopted the following technical scheme that：A kind of municipal well lid, including cylinder, ring flange, lid
Body and free bearing, the ring flange are located at cylinder body bottom, and the reinforcement of outwardly convex, the ring flange are provided with the middle part of the cylinder
Bottom is provided with rubber blanket, and the lid is located on cylinder, and the free bearing is arranged on the inside of lid, is provided with and turns in the free bearing
Axle, is welded with gag lever post in the middle part of the rotating shaft, be additionally provided with the reinforcement being interspersed, on the lid on the inside of the lid
Permeable hole is provided with, hook and bearing are welded with the cylinder, protection network on the hook, is provided with, the gag lever post is passed through
Bearing, the gag lever post bottom welding have block.
Preferably, the cylinder is welded with ring flange, cylinder sound construction is kept.
Preferably, being provided with screen pack in the permeable hole, sewage can be filtered.
Preferably, rubber ring is provided with the inside of the lid, with bumper and absorbing shock function.
Preferably, through hole is provided with the ring flange and rubber blanket, conveniently installed.
Beneficial effects of the present invention are：The flange tray bottom of the setting of setting is provided with rubber blanket, can possess buffering work(
Energy；The reinforcement being interspersed is additionally provided with the inside of the lid of setting, the structural strength for lifting lid is high, in the cylinder of setting
Portion is provided with the reinforcement of outwardly convex, lifts the structural strength of cylinder；The protection network of setting falls after being prevented from lid breakage
Fall, keep using safety；The gag lever post bottom welding of setting has block so that lid has anti-theft feature.
Description of the drawings
Fig. 1 is a kind of structure chart of municipal well lid of the present invention.
Fig. 2 is a kind of free bearing structure chart of municipal well lid of the present invention.
