Description

Safety well cover

Technical Field

The utility model belongs to the field of road facilities, and particularly relates to a safety well cover.

Background

The well cover is round in shape all the time, and the well cover is basically as large as the outer edge of a well head. Generally, the lower part of a sewer or other well covers is wet, the sewer well wall is built by bricks or other building materials, certain pulverization can be generated after a long time, and the well cover is easy to damage due to the pressing and the impact of vehicles or external gravity objects. Some of the vehicles can also have side inclination, and more serious the vehicles can collapse and sink, so that the vehicles are unsafe to drive, the traveling of personnel is influenced, the city appearance and the landscape of the city are greatly influenced, and great potential safety hazards exist.

Disclosure of Invention

The utility model aims to overcome the defects of the prior processing technology and provide a safety well lid, thereby effectively solving the problems in the prior art.

The technical scheme adopted for realizing the purpose of the utility model is as follows: a safety well lid is characterized in that: the cover body is connected with the outer ring plate through a hinge, an inner attachment ring is fixed on the inner ring of the back surface of the outer ring plate, an outer attachment ring is fixed on the outer ring of the back surface of the outer ring plate, a plurality of ribs are uniformly fixed between the inner attachment ring and the outer attachment ring in the radial direction, and circular holes are formed in the outer ring plate corresponding to the region between the adjacent ribs; the outer edge of the inner attached ring is provided with two platforms for embedding the cover body.

The number of the ribs is eight.

The height of the rib, the inner attached ring and the outer attached ring is the same and is 6-10 cm.

The radial width of the outer ring plate is 30 cm.

The surface of the cover body is a curved surface, and the center point of the cover body is 5 cm higher than the outer edge; a plurality of reinforcing ribs are uniformly arranged on the back surface of the cover body in the radial direction; the cover body is provided with a strip-shaped hole for inserting the well lid hook.

The outer edge of the outer ring plate is in a sawtooth shape or an arc shape, and different shapes are installed on different road sections, so that the sewer well cover is safer, and the sewer well cover can become a bright landscape of an urban street.

The utility model has the beneficial effects that: an outer ring plate with the width of 30 cm is arranged on the periphery of the cover plate, and the impact force and the pressure of the periphery to the cover plate are reduced due to the fact that the periphery of the cover plate is widened by 30 cm. The back of the outer ring plate is also reinforced by 8 vertical ribs, so that the adhesive force is increased and the bearing capacity is increased. The cover plate is convex, the central point is 5 cm higher than the outer edge, because the stress point is arranged at the outer edge of the circle, the external impact force and the pressure are uniformly dispersed to the periphery of the circle, the bearing force is increased, the impact force is reduced, and the service life of the well cover is prolonged. The design solves the defects of cover turning, sinking and side turning of the well cover, does not increase the cost greatly, improves the safety factor greatly, reduces the potential safety hazards of personnel and vehicles, and enables the city appearance of the city to be changed.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Embodiment 1, see fig. 1-5, a safety well lid, its characterized in that: the cover body 1 is connected with an outer ring plate 4 through a hinge 7, an inner attachment ring 2 is fixed on an inner ring on the back surface of the outer ring plate 4, an outer attachment ring 3 is fixed on an outer ring on the back surface of the outer ring plate 4, a plurality of ribs 5 are uniformly fixed between the inner attachment ring 2 and the outer attachment ring 3 in the radial direction, and circular holes 8 are formed in the outer ring plate 4 corresponding to the areas between the adjacent ribs 5; the outer edge of the inner attachment ring 2 is provided with two platforms 6 for embedding the cover body 1.

The number of the ribs 5 is eight.

The height of the rib 5, the height of the inner attached ring 2 and the height of the outer attached ring 3 are the same and are 6-10 cm.

The radial width of the outer ring plate 4 is 30 cm.

The surface of the cover body 1 is a curved surface, and the center point of the cover body 1 is 5 cm higher than the outer edge; a plurality of reinforcing ribs are uniformly arranged on the back surface of the cover body 1 in the radial direction; the cover body 1 is provided with a strip-shaped hole 9 for inserting the well lid hook.

The cover plate 1 has a diameter of 80 cm.

The thickness of the outer ring plate 4, the ribs 5, the inner attached ring 2 and the outer attached ring 3 is the same and is 0.6 cm, and the outer ring plate, the ribs, the inner attached ring and the outer attached ring are cast into a whole by adopting the same material.

The thickness and material can be determined according to the bearing capacity of different roads and different road surfaces, and the general road surface is made of cast iron with the thickness of 0.6 cm.

The installation method comprises the following steps:

the rib ribs 5, the inner attached ring 2 and the outer attached ring 3 are completely solidified and bonded on the ground after the asphalt and cement road is poured, and the circular hole 8 formed in the outer ring plate 4 can completely exhaust air in the surface when the air sinks, so that the outer ring plate is solidified and is installed smoothly.
