Abstract

The utility model relates to an anti-sedimentation inspection well cover, the technical problem to be solved is to provide an inspection well cover characterized by no easy sedimentation, simple structure, and lower cost. The technical scheme of the anti-sedimentation inspection well cover is characterized in that: the anti-sedimentation inspection well cover comprises a base fixed on the road surface and a moveable cover body installed on the base body, the anti-sedimentation inspection well cover is characterized in that: the base comprises a loop body used for installing the movable cover body, the axis of the loop body is arranged along the vertical direction, and a loop of suspension edge is manufactured along the top, the radial width of the suspension edge is 8-10cm, at least eight reinforcing ribs used for supporting the suspension edge are manufactured at the external surface of the loop body; an inner loop used for supporting the movable cover body is manufactured at the inner wall of the loop body, the radial width of the inner loop is 2.5-3.5cm, and at least eight reinforcing ribs used for supporting the inner ring are manufactured at the inner wall of the loop body. The vertical distance between the upper surface of the inner loop and the upper surface of the suspension edge equals the thickness of the movable cover body.

Description

A kind of anti-settling inspection shaft lid

Technical field

The utility model relates to a kind of inspection shaft lid, is specifically related to a kind of anti-settling inspection shaft lid.

Background technology

Along with economic, social development, the inspection inspection shaft of drainage system, electrical cable, and the inspection shaft of communication network and gas flue is more and more on road.Common inspection shaft lid is made up of the Moveable lid body that is fixed on the pedestal on the road surface and be installed on the pedestal, and pedestal and Moveable lid body all are beneficial to passing through of pedestrian, vehicle with the road surface is roughly concordant.The pedestal of this type of inspection shaft lid and the contact area on ground are less usually, and when vehicle pressed a side of pedestal, opposite side was because discontinuity; Have a trend that is upturned; In the course of time, can become between pedestal and the ground loosening and even sink, pedestal even can be crushed out of shape sometimes; How to prevent the sinking of inspection shaft lid, become producer's urgent problem.

The utility model content

The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of inspection shaft lid is provided, and this inspection shaft lid should have the sinking of being difficult for, simple in structure, lower-cost characteristics.

For realizing above purpose, the technical scheme below the utility model has adopted:

A kind of anti-settling inspection shaft lid; Comprise and be fixed on the pedestal on the road surface and be installed in the Moveable lid body on the pedestal; It is characterized in that: said pedestal comprises the circle body that is used to install Moveable lid body, and the axis of said circle body arranges that vertically its top sides is hung the limit along being shaped on a circle; The radial width on said extension limit is 8-10cm, is shaped at least eight reinforcing ribs that are used to support said extension limit on the external surface of circle body in addition; Said circle body inwall is shaped on the inner ring that is used for the said Moveable lid body of support, and the radial width of said inner ring is 2.5-3.5cm, and the inwall of circle body is shaped at least eight reinforcing ribs that are used for the said inner ring of support in addition.

The upper surface of said inner ring equates with the thickness of vertical distance of hanging the limit upper surface and Moveable lid body.

The soffit on said extension limit is shaped on a circle bead around its outer.

Said circle body, extension limit, inner ring, bead and the cast molding of reinforcing rib one.

The beneficial effect of the utility model is: the pedestal of the utility model is that the extension limit of 8-10cm contacts with the road surface through radial width; Increased the contact area between pedestal and the road surface; Make when vehicle is pressed on the pedestal; Weight distribution is more even, can not make the opposite side perk of pedestal, has solved the inspection shaft lid owing to the long-term problem of sinking of becoming flexible.And the utility model is simple in structure, and cost is also cheaper.

The specific embodiment

Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.

As shown in Figure 1, a kind of anti-settling inspection shaft lid comprises being fixed on the pedestal on the road surface and being installed in the Moveable lid body 4 on the pedestal, and its mounting means is not described in detail at this with reference to common inspection shaft lid.

Pedestal is loosening when preventing pressurized; The utility model has been made following improvement: said pedestal comprises the circle body 1 (diameter is confirmed according to the inspection shaft openings of sizes, recommends to select for use 700mm) that is used to install Moveable lid body, and the axis of said circle body is vertically arranged; Its top sides is hung limit 2 along being shaped on a circle; The radial width on said extension limit be 8-10cm (so-called radial width is promptly hung the outer on limit and the distance of circle body external cylindrical surface, the width of comparing conventional inspection shaft lid increase be twice about, increased contact area greatly with ground); After pedestal installed, the upper surface of hanging the limit was concordant basically with the road surface; In order to gain in strength, prevent to hang the limit and be crushed out of shape, be shaped at least eight reinforcing ribs 6 (figure is shaped on 8 equally distributed reinforcing ribs) that are used for supporting said extension limit on the external surface of said circle body in addition.

Said circle body inwall is shaped on the inner ring 3 that is used for the said Moveable lid body of support; The radial width of said inner ring is 2.5-3.5cm (specifically confirming according to actual conditions); The inwall of circle body is shaped at least eight reinforcing ribs (specifically confirm according to actual conditions, shown in the figure be 16) that are used for the said inner ring of support in addition.The upper surface of said inner ring equates with the thickness of vertical distance of hanging the limit upper surface and Moveable lid body, make that movable well lid installs after, its upper surface is concordant with extension limit and road surface.

In order to increase the intensity of pedestal; The soffit on said extension limit is shaped on a circle bead 7 (thickness 1cm) around its outer, also can hang some strip reinforcing rib 6-1 (quantity of strip reinforcing rib is 8 among the figure) that thickness equates with said bead of limit soffit increase simultaneously.

Said circle body, extension limit, inner ring, bead and reinforcing rib adopt ductile iron or the cast molding of aluminium alloys one to gain in strength.

Dotted line is depicted as the skeleton 5 of movable well lid among Fig. 2.
