Background
The cast iron well lid is usually the target of stealing owing to have the retrieval value, for this reason, all adopts the cement well lid, and the retrieval value of cement well lid material is little, can avoid becoming the target of stealing, nevertheless simultaneously because cement well lid wearability is lower, causes well lid surface to produce wearing and tearing or appear sunkenly easily when vehicle or people long-time contact friction, reduces the life of cement well lid, also does not benefit to people's normal walking and vehicle and rides.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a simple structure and stand wear and tear cement well lid.
In order to achieve the above purpose, the utility model provides a following technical scheme: a high wear-resistant cement well lid comprises a well lid body; the upper end face of the well lid body is provided with a wear-resistant bearing layer, and the upper end face of the wear-resistant bearing layer is provided with an outer wear-resistant layer; the outer wear-resistant layer sequentially comprises a zirconium-titanium alloy coating, a tungsten carbide coating and a nano chromium oxide coating from inside to outside.
Set up the zirconium titanium alloy coating, can effectively improve the intensity of cement well lid up end, scribble and established the tungsten carbide coating, can improve the wearability of cement well lid up end, scribble in the tungsten carbide coating outside and established nanometer chromium oxide coating, can still make cement well lid up end have superstrong wearability after the tungsten carbide coating damages, through the cooperation of above structure, effectively improved cement well lid bulk strength and wearability, thereby its application range has been enlarged.
The utility model discloses further set up to: the thickness of the zirconium-titanium alloy coating is one hundred twenty to two hundred microns.
By adopting the technical scheme, the thickness of the zirconium-titanium alloy coating is one hundred twenty to two hundred micrometers, so that the overall manufacturing cost of the cement well lid can be ensured.
The utility model discloses further set up to: the thicknesses of the zirconium-titanium alloy coating, the tungsten carbide coating and the nano chromium oxide coating are the same.
By adopting the technical scheme, the thicknesses of the titanium alloy coating, the tungsten carbide coating and the nano chromium oxide coating are the same, so that the integral wear-resisting property of the outer wear-resisting layer is ensured.
The utility model discloses further set up to: the manhole cover is characterized in that a reinforced layer is arranged in the manhole cover body, and the reinforced layer is a honeycomb-shaped honeycomb piece made of spring steel.
By adopting the technical scheme, the manhole cover body is internally provided with the reinforced layer, and the reinforced layer is a honeycomb-shaped honeycomb piece made of spring steel; thereby can ensure the structural strength and the tensile effect of well lid body.
The utility model discloses further set up to: the wear-resistant bearing layer is made of ceramic materials or silicon carbide materials.
By adopting the technical scheme, the wear-resistant bearing layer is made of the ceramic material or the silicon carbide material, so that a smooth bearing groove can be formed on the surface of the cement well lid body, and the coating of the outer wear-resistant layer is facilitated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a partial structural view of a reinforcement layer according to the present invention;
reference numbers in the drawings and corresponding part names: 1-a well lid body, 2-a wear-resistant bearing layer, 3-an outer wear-resistant layer, 3 a-a zirconium titanium alloy coating, 3 b-a tungsten carbide coating, 3 c-a nano chromium oxide coating and 4-a reinforcing layer.
Detailed Description
An embodiment of the present invention is further explained with reference to fig. 1 to 2.
A high wear-resistant cement well lid comprises a well lid body 1; the upper end surface of the well lid body 1 is provided with a wear-resistant bearing layer 2, and the upper end surface of the wear-resistant bearing layer 2 is provided with an outer wear-resistant layer 3; the outer wear-resistant layer 3 sequentially comprises a zirconium-titanium alloy coating 3a, a tungsten carbide coating 3b and a nano chromium oxide coating 3c from inside to outside.
Through setting up zirconium titanium alloy coating 3a, can effectively improve the intensity of cement well lid up end, established tungsten carbide coating 3b by scribbling, can improve the wearability of cement well lid up end, established nanometer chromium oxide coating 3c by scribbling in the tungsten carbide coating 3b outside, can damage the back at tungsten carbide coating 3b, still can make the cement well lid up end have superstrong wearability, through the cooperation of above structure, cement well lid bulk strength and wearability have effectively been improved, thereby its application range has been enlarged.
Further: the thickness of the zirconium titanium alloy coating 3a is one hundred twenty to two hundred micrometers.
The thickness of the zirconium-titanium alloy coating 3a is one hundred twenty to two hundred micrometers, so that the manufacturing cost of the whole cement well cover can be guaranteed.
