Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of well lid, concretely is a kind of anti-settling spheroidal graphite cast iron well lid. BACKGROUND

[0002] Spheroidal graphite cast iron well lid is a common road facility. It is made of spheroidal graphite cast iron, and the graphite is spherical by spheroidizing and inoculation treatment, which greatly improves the mechanical properties of cast iron. It has the advantages of high strength, good toughness, corrosion resistance, good plasticity, etc. Its tensile strength is greater than or equal to 420 MPa, its yield strength is greater than or equal to 300 MPa, its impact value is similar to that of medium carbon steel, and its corrosion amount in 90 days is only 1 / 40 of that of steel pipe. The shape is generally divided into round and square, and the round is often used in urban road administration, and the square is often used in the countryside or cable well. It is widely used in water supply, sewage, power and other fields.

[0003] The existing well lid is used when the foundation under the well lid is not properly treated and not fully compacted during road construction. With repeated rolling of vehicles, the foundation gradually subsides, causing the well lid to sink synchronously. The traditional well lid and well seat connection method is single, and the well lid is easy to displace under the action of vehicle load. Long-term accumulation causes settlement, which can cause potholes on the road surface and increase the risk of driving, so improvement is needed. UTILITY MODEL CONTENT

[0010] Preferably, a sliding hole is formed in the middle of the limiting block, and the anti-dropping ring is fixedly connected to the left side of the sliding rod, and the outer diameter of the anti-dropping ring is greater than the inner diameter of the sliding hole.

[0011] Preferably, the well lid body comprises a well body, the well body is fixedly connected to the inner ring of the gasket ring, the top of the well body is fixedly connected with a cover body, the inner ring of the cover body is hingedly connected with a top cover, and the bottom of the top cover is fixedly connected with an elastic strip.

[0012] Preferably, the inner ring of the well body is fixedly connected with a limiting ring, and the top of the limiting ring is in contact with one end of the bottom of the elastic strip.

[0013] Compared with the prior art, the anti-settling ductile iron well lid has the following advantages

[0014] Beneficial effects:

[0015] 1. The anti-settling ductile iron well lid is provided with the anti-settling mechanism, the mounting seat in the anti-settling mechanism is fixed on the top of the gasket ring, and the four mounting seats are distributed in a cross shape, so that the uniformity of force of the well lid is ensured. When the well lid is rolled by a vehicle, the well lid is subjected to pressure, and the anti-settling mechanism starts to work. The sliding strip in the mounting seat can slide in the cavity, the arc-shaped plate connected to the outer side of the sliding strip moves, and the anti-settling thorn on the outer wall of the arc-shaped plate is inserted into the surrounding foundation soil. At the same time, the limiting blocks on the front and rear sides of the sliding strip slide on the sliding rod, and the spring plays a buffering and resetting role. In the process of repeated rolling of the vehicle, the anti-settling thorn can tightly hold the foundation soil, prevent the well lid from sinking with the foundation, and the buffering effect of the spring reduces the impact force received by the well lid, further reduces the possibility of settlement, greatly improves the stability of the well lid, and guarantees the safety of the road.

[0016] 2. The anti-settling ductile iron well lid is provided with the well lid body comprising a well body and a cover body, the top cover is hingedly connected to one side of the inner ring of the cover body through a hinge, and the elastic strip at the bottom of the top cover cooperates with the limiting ring in the inner ring of the well body. When the vehicle passes through the well lid, the vibration generated will cause the displacement of the well lid, but the elastic strip and the limiting ring are in contact and generate elastic force, thereby limiting the displacement amplitude of the top cover and the entire well lid. This design changes the single connection mode of the traditional well lid and well seat, and through the interaction of the elastic strip and the limiting ring, the displacement of the well lid is effectively controlled under the action of the vehicle load. In the long-term use process, the settlement problem caused by the displacement accumulation of the well lid is avoided, the appearance of the road surface pit is reduced, the driving risk is reduced, the overall use performance of the road is improved, and the contact area of the gasket ring and the foundation soil is increased, and the anti-settling purpose is further achieved.
