Abstract
The utility model discloses an invisible well cover. The invisible well cover comprise a cover plate and a base, wherein the cover plate is of a round structure. The invisible well cover is characterized in that a circular rib is arranged on the cover plate, six radiation ribs are arranged on the cover plate outside the rib, and the central angle of the radiation ribs is 60 degrees; the base is of a circular truncated cone shape and is gradually shrunk downwards. Two circular ribs on the cover plate are replaced by the circular rib, the weight of the well cover is reduced as far as possible on the premise that bearing force is guaranteed, and stress distribution of the well cover is relatively even. Because radiation ribs inside the rib are removed and only the radiation ribs outside the rib remain, the weight of the well cover is reduced, stress distribution of a bottom plate of the well cover is even, local damage is avoided and the radiation ribs outside the rib remain. Being designed to be the circular truncated cone shape which is gradually shrunk downwards, the base can be more tightly installed, and can not easily move up and down to bring noise.
Description
Technical field
The utility model relates to a kind of invisible well cover.
Background technology
At present, casting iron well lid form commonly used respectively has advantage for circle rib shape and cross-ribbed, but the form of structure of well lid is still the design of the experience of continuing to use, and does not carry out the computational analysis of scientific system, can not give full play to the high-strength mechanical characteristic of ductile iron, cause waste of material.Along with sharply increasing of casting iron well lid quantity and escalating of material price, structure optimization to ductile cast iron manhole cover just seems very necessary, and, because the cylindrical structural of well lid, well lid is moved up and down easily, for having brought huge noise in the life, therefore, by improving form of structure, weight reduction, when reducing cost, improve bearing capacity and impulse fatigue resistance, and the effect of accomplishing noise abatement.
Summary of the invention
The purpose of this utility model is, the invisible well cover that a kind of bearing capacity is high, the shock resistance fatigue resistance is good and noise is little is provided.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of invisible well cover comprises cover plate and base, and described cover plate is circular configuration, it is characterized in that, described cover plate is provided with a circle circle rib, and the cover plate beyond the circle rib is provided with six radial ribs, and the center of circle angle of described radial rib is 60 °; Described base is downward diminishing truncated cone-shaped.
As preferably, described cover sheet thickness is 15mm-20mm.
As preferably, the radius of described round rib is 150mm-180mm.
The utility model is kept to a circle with the circle of two on cover plate circle rib, under the prerequisite that guarantees bearing capacity, alleviates as far as possible the weight of well lid, and makes the well lid stress distribution comparatively even.And will justify rib and remove with interior radial rib, only the radial rib beyond the remaining circle rib when reducing well lid weight, for making the stress distribution on the well lid base plate even, is avoided local failure, keeps the radial rib in the circle rib outside.Base designs becomes downward diminishing truncated cone-shaped, and base can be installed more closely, thereby difficult moving up and down brought noise.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Label among the figure is, 1, cover plate; 2, base; 3, justify rib; 4, radial rib.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, a kind of invisible well cover that present embodiment proposes, comprise cover plate 1 and base 2, cover plate 1 is circular configuration, and the radius of cover plate 1 is 210mm, and the thickness of cover plate 1 is 15mm, cover plate 1 is provided with a circle circle rib 3, the radius of circle rib 3 is 150mm, and the cover plate 1 beyond the circle rib 3 is provided with six radial ribs 4, and the center of circle angle of radial rib 4 is 60 °.The utility model is kept to a circle with the circle of two on the cover plate 1 circle rib 3, under the prerequisite that guarantees bearing capacity, alleviates as far as possible the weight of well lid, and makes the well lid stress distribution comparatively even, gives full play to the mechanical property of ductile iron.And will justify rib 3 and remove with interior radial rib 4, only the radial rib 4 beyond the remaining circle rib 3 when reducing well lid weight, for making the stress distribution on the well lid even, is avoided local failure, keeps the radial rib 4 in circle rib 3 outsides.In conjunction with Fig. 2, base 2 is downward diminishing truncated cone-shaped, and base 2 is designed to downward diminishing truncated cone-shaped, and base 2 can be installed more closely, thereby difficult moving up and down avoids bringing noise.
Claims (3)
1. an invisible well cover comprises cover plate and base, and described cover plate is circular configuration, it is characterized in that, described cover plate is provided with a circle circle rib, and the cover plate beyond the circle rib is provided with six radial ribs, and the center of circle angle of described radial rib is 60 °; Described base is downward diminishing truncated cone-shaped.
