Abstract
The utility model relates to a colliery support stand specifically is an inside seal face melts colliery support stand that covers copper alloy and scribble layer structure. The problem of the colliery perishable stand that causes of support stand inside seal face is scrapped is solved, a colliery support stand, the structure includes: that inside seal face covers the copper alloy and scribbles the layer structure for melting outer cylinder body, well cylinder body, the post of living, outer cylinder body cup joint well cylinder body through big uide bushing, well cylinder body is through the little uide bushing cover post of taking over a job, well cylinder body includes casing wall, cylinder bottom, outer cylinder body includes the casing wall, the cylinder bottom, and the casing wall inboard of cylinder body is equipped with the copper -aluminium alloy coating outside. The utility model discloses a technique effect: because copper -aluminium alloy has characteristics such as the fusing point is low, anticorrosive, the wearability is good, make cylinder after the restoration under the circumstances that synthesis intensity does not reduce, the processing cost was lower in addition all far above former base member its performance and life -span.
Description
Technical field
This utility model relates to a kind of colliery bracket upright post, is specially the colliery bracket upright post of a kind of inner sealing surface cladding copper alloy coating structure.
Background technology
Recently as popularizing of the large-scale fully-mechanized mining equipment in colliery, high-end hydraulic vertical prop make consumption in increase year by year, the processing overwhelming majority of the current column inner sealing surface of China adopts the forming technique of heavy boring+right boring+cold rolling, and this just easily occurs that hidden danger has been buried in spot corrosion, corrosion to column inner sealing surface in the future in using. Because cold rolling technique is the plastic deformation of a kind of " low ebb is filled out on peak ", especially easy in the environment of aqueous medium there is ionisation effect, makes column inner sealing surface " spot corrosion " occur thus causing seal failure. Therefore column is scrapped has number every year with ten thousand more than, wastes very surprising.
In prior art, have been proposed for the metal alloy the using anticorrosive anti-wear design as column inner sealing surface coating, such as 201010226686.8, the laser cladding method of mine hydraulic support column, the bright laser cladding method disclosing a kind of mine hydraulic support column, column after using chromium nickel stainless steel laser reinforcing to process, its matrix surface hardness reaches HV410, and service life is 5-10 times that adopts chromium plating column. 201210159340.X, the column of a kind of hydraulic support, described laser cladding layer is stainless steel cladding.
Summary of the invention
This utility model easily corrodes, in order to solve colliery bracket upright post inner sealing surface, the problem causing column to scrap, it is provided that a kind of inner sealing surface is the colliery bracket upright post of cladding copper alloy coating structure.
The technical solution of the utility model is, a kind of inner sealing surface is the colliery bracket upright post of cladding copper alloy coating structure, structure includes: outer cylinder body, middle cylinder body, post of living, described outer cylinder body is by cylinder body in the socket of big fairlead, middle cylinder body is taken over a job post by little fairlead set, middle cylinder body includes casing wall, cylinder bottom; Outer cylinder body includes casing wall, cylinder bottom, is provided with albronze coating inside the casing wall of outer cylinder body.
Technique effect of the present utility model: owing to albronze has the features such as fusing point is low, anticorrosion, wearability are good, making the cylinder barrel after reparation when comprehensive strength does not reduce, its serviceability and life-span are all far above protocorm, and processing cost is relatively low.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is outer cylinder body structural representation;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
As schematically shown in Figure 1, a kind of inner sealing surface is the colliery bracket upright post of cladding copper alloy coating structure, structure includes: outer cylinder body 1, middle cylinder body 2, post 5 of living, described outer cylinder body 1 is by cylinder body in the socket of big fairlead 3, middle cylinder body 2 overlaps, by little fairlead 4, post 5 of taking over a job, middle cylinder body 2 includes casing wall, cylinder bottom; Anticipating as shown in Figure 2,3, outer cylinder body 1 includes casing wall 7, cylinder bottom 6, is provided with albronze coating 8 inside the casing wall 7 of outer cylinder body.
Albronze coating 8 thickness is: 0.3 0.8mm.
The composition of this Albatra metal:
Al11.73%��Cu83.81%��Fe0.54%��Mn2.03%��
