Abstract

The utility model relates to a novel nodular cast iron hidden well cover which has the following advantages: high strength, no easy deformation and high corrosion resistance. The novel nodular cast iron hidden well is composed of the following components: stainless steel corners (1), stainless steel strips (2) and a base plate (3). The novel nodular cast iron hidden well cover is characterized in that: an upper layer is composed of the stainless steel corners (2) and the stainless steel corners (1); and the upper layer is provided with four stainless steel corners (1). According to the novel nodular cast iron hidden well cover, the nodular cast iron is changed for being used as a base; and the stainless steel corners (2) are welded, thereby settling the problems of easy deformation and low corrosion resistance of a base well cover because of high ductility. The nodular cast iron hidden well cover is used as the base. The nodular cast iron hidden well cover has the following advantages: high strength, low elongation rate, no easy deformation, high corrosion resistance, difference from layered dropping of steel after corrosion, low cost and improved production efficiency. The nodular cast iron hidden well cover base is manufactured through die machining. The homogeneity and production power are far higher than the welding speed and quality of each steel-plate well cover. Furthermore the lubrication cost is reduced.

Description

Novel ductile iron invisible well cover
Technical field
The utility model relates to a kind of well lid, particularly a kind of novel ductile iron invisible well cover.
Background technology
Product on the market is the stainless steel invisible well cover that steel plate soldering stainless steel bar forms now; Its shortcoming is that the invisible well cover that is welded of steel plate is because the extension performance of steel is good; The well lid of moulding is prone to be out of shape because of stressed; Make the stone material of mating formation inside damaged easily, the stone material of mating formation in this stainless steel invisible well cover top rolls once automobile and is easy to breakage, crackle occurs.Because stone material intensity is very low, this just requires below the stone material support force of well lid very high.And the antiseptic property of steel is bad, under the environment of inspection shaft, be easy to corrosion, and layering comes off after the corrosion, does not have intensity more after the steel corrosion has approached.Also have in addition whole are stainless steel invisible well covers that stainless steel is welded, though this stainless steel invisible well cover has solved the problem of corrosion, it still is the character of steel; Ductility is still high; Still easy deformation can't resolve because of stressed yielding situation, and cost is very high again.
Summary of the invention
Technical problem according to above-mentioned proposition; The utility model proposes the novel ductile iron invisible well cover that a kind of intensity is high, not yielding, corrosion resistance is high; Form by stainless steel angle (1), stainless steel strip (2), base plate (3); It is characterized in that the upper strata by stainless steel strip with form with the stainless steel angle, lower floor is a base plate.The upper strata is provided with four stainless steel angles.
The beneficial effect of the utility model is: make into ductile iron as the basis, the soldering stainless steel bar has solved good and cause yielding of basic well lid ductility and rust stable problem not at present.Ductile iron intensity is high, and ductility is little not yielding, and corrosion resistance is high, and the layering that also is different from steel after its corrosion comes off, and cost is also low.Feasible stone material of mating formation is cracky not, has improved productivity ratio.In addition, the ductile iron invisible well cover is cast out through particular mold processing, and its homogeneity and production capacity are higher than the general steel plate well lid far away, and the speed of welding and quality have also had lifting greatly, have reduced cost simultaneously.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
According to shown in Figure 1, the bottom of the utility model is base plate (3), adopts the ductile iron invisible well cover as the basis.Upper strata soldering stainless steel bar (2) and four stainless steel angles (1), and four stainless steel angles (1) form through hot investment casting.Be the common well lid with the steel plate welding before improving, improve the back for being welded with the invisible well cover of stainless steel strip (2) and stainless steel angle (1), stainless steel strip (2) and stainless steel angle (1) have increased the support force of well lid.After automobile is pressed, owing to the unique texture of the utility model is shared stressed, thereby guarantee that the stone material and the square brick of mating formation are again not damaged, the effect after the improvement is better.Because the utility model is embedded in the road surface, can also guarantee aesthetics after feasible the installation.

Claims (2)
