Abstract

The utility model relates to a high-adjustable anti-stealing checking well cover, and belongs to public facilities. In the municipal construction, a plurality of checking wells are arranged on the ground. Since road surfaces are repaired to result in road beds generating change, well covers are uneven. The existing well covers do not have anti-stealing devices, and are easily lost, which brings danger and inconvenience for passing pedestrians and vehicles. The high-adjustable anti-stealing checking well cover adopts a well mouth 4 with a certain taper and high-adjustable gaskets 3, and the well mouth 4 and the high-adjustable gaskets 3 are matched. The high-adjustable gaskets are appropriately increased according to the height change of the road bed, and the well cover and the road surfaces can be kept evenly. The well cover is connected with the well mouth by an anti-stealing iron chain connector 6, and each fastener adopts cocked hat screw bolts. Therefore, the high-adjustable anti-stealing checking well cover has anti-stealing effect.

Description

High-adjustable anti-stealing checking well cover

The utility model relates to the manhole cover in the urban operating mechanism.

In the town road construction,, for ease of current check and mediation, in certain distance, all leave manhole, and be furnished with well lid at well head owing under the road surface many underground pipelines are arranged.Yet road will keep in repair the road surface at regular intervals, usually, be on former road bed, after overhauling, to overlay one deck hituminous sandstone again, or concrete, the road surface after its result will cause overhauling is higher than former road surface, the roadbed after causing manhole cover to be lower than to increase and low-lying injustice.Another shortcoming that existing manhole also exists is exactly that well lid is easy to lose, and this is because well lid is directly to cover the cause that does not have hookup on well head.The manhole that does not have well lid is dangerous, therefore makes troubles to pass by on one's way pedestrian and vehicle.

The utility model improves at the existing shortcoming of existing manhole cover, can heighten anti-stealing manhole cover thereby made a kind of brand-new device one.Can heighten anti-stealing manhole cover by well lid, well head, heighten packing ring three parts and form.

Fig. 2 is the well lid vertical view.

Fig. 3 is the well head front view.

Fig. 4 is a fish eye view.

Fig. 5 is for heightening the packing ring front view.

Fig. 6 is for heightening the packing ring vertical view.

Fig. 7 is for well lid and heighten packing ring well head assembling schematic diagram.

Fig. 8 is a partial enlarged drawing.

Fig. 9 is that A is to view.

Among Fig. 7,1, well lid, 2, the cocked hat bolt, 3, heighten packing ring, 4, well head, 5, antitheft iron chains hookup anchoring filament hole, 6, antitheft iron chains hookup, 7, antitheft iron chains.

The utility model is achieved in that the fit system that changes existing well head and well lid such as Fig. 7, becoming the round platform cooperation is that the cone platform cooperates, therefore well head 4 upper inside wall are the cone platform with certain angle, be drilled with a plurality of holes in its circular upper surface along circumference, the connection of being convenient to utilize cocked hat bolt 2 and heightening packing ring, the inwall bottom is to connect cone platform bottom on the round platform, and is drilled with a hole at the round platform sidewall, in order to the cocked hat bolt antitheft iron chains hookup 6 is fixed thereon.

Heightening packing ring 3 its upper inside wall is frustum, and its tapering is consistent with well head 5 taperings, and the bottom is a round platform, equates with well head 5 internal diameters.The upper surface is circular, and is drilled with a plurality of countersunk bolt through holes silk corresponding with well head hole along circumference and cooperates, so that fastening with well head.In order to strengthen heightening contacting of packing ring and road surface, prevent the impact lower slider of packing ring at vehicle, also have a plurality of wedge shape anchor flukes in packing ring upper surface outer rim.

The well lid upper surface is for having certain thickness frustum, its tapering and well head and to heighten packing ring consistent, there are a plurality of floor reinforcing ribs perpendicular to this end face the well lid lower surface, to increase its compressive strength, wherein, the reinforcing rib that intersects with periphery and the angle of end face equal the end face tapering.On certain floor reinforcing rib, antitheft iron chains is arranged, and well lid and well head are locked by antitheft iron chains hookup.

Antitheft iron chains hookup 6 upper ends are cylindrical shape, are drilled with the countersunk bolt hole, and the lower end has earrings to be parallel with antitheft iron chains 7.

Can heighten antitheft manhole cover is to use like this: after manhole is built up, puzzle well head 4, with install iron chains 7 and and the antitheft iron chains hookup 6 usefulness cocked hats that link of well lid 1 be bolted on the inside wall silk hole of well head 4, cover well lid then, well lid will have anti-theft feature at this moment.After increase through overhauling on the road surface, add high level according to the road surface, suitably increase and heighten the well lid that Height Adjustment that packing ring 3 utilizes packing ring itself causes because of the variation of pavement-height and the level disparity of roadbed, thereby keep the road surface concordant with manhole.Fastening the same with antitheft iron chains hookup and well head of packing ring and well head fastening all is to adopt the cocked hat bolt, and non-special tool is difficult to revolve and opens, thereby has improved antitheft reliability.The well lid 1 that will have antitheft hookup at last is fastened on 5 holes of well head, covers well lid, heightens process and finish well lid.

The utility model adopts tapering to heighten packing ring and supporting with it well head and well lid, heightens packing ring by increase and decrease and reaches and regulate well lid and just keep the concordant purpose in road surface, utilizes antitheft iron chains hookup that well lid and well head are locked.Owing to adopted the cocked hat bolt, further improved antitheft reliability.In addition, well lid and well head or heighten packing ring cooperating between mutually and adopt taper fit make it to have the feature from compressing, thereby well lid is difficult for sliding or upset, have improved the safety of the shock-resistant and roll off of well lid.Adopt the utility model to construct, easy to use, adjust flexibly, can solve worn-out sick because of the low-lying injustice of the caused manhole of pavement recapping preferably, and the well lid difficult problem that is easy to lose.

Claims
