Abstract
The utility model discloses an abrasion resistant ring with cemented carbide wearable surface to solve the problem of the failure of the main abrasion resistant layer due to the wearable performance mismatching of the main and the auxiliary wearable surfaces. The utility model comprises a matrix, the abrasion resistant layer on the surface of the matrix and the wall of the discharging hole. The abrasion resistant layer on the wall of the discharging hole is formed by Z-shaped cemented carbide tablets, Z-shaped cemented carbide sector plates are arranged to form the integral abrasion resistant layer on the surface of the matrix, and arc strips are spliced to form the ring on the outer surface of the matrix. All of the wearable surfaces of the abrasion resistant ring are provided with the cemented carbide materials with different shapes and elements to make the wearable performance of different parts match integrally, therefore avoiding the problem of early damage of certain parts and prolonging the service life of the integral abrasion resistant ring. The cemented carbide blocks above are chosen to form the abrasion resistant ring with different sizes and shapes, which makes the manufacturing and processing easy. The chosen Z-shaped sector plate can prevent concrete from being scoured and mortar from leaking due to extrusion, as well as the sector plate can enhance the sealing performance.
Description
Technical field: it is the concrete pump accessory that the utility model relates to a kind of building machinery.
Background technique: wearing plate in the concrete pump and wear ring (also being cutting ring) are a pair of easily damaged partss, they are in a kind of ten minutes rugged environment when work, and bearing complicated force-bearing situation, therefore, wearing plate and wear ring are easy to early failue, particularly owing to wear ring residing bad working environments and stressed difference when working, compared with the easier early damage that occurs of wearing plate, and wearing plate that more renews and wear ring are a job of wasting time and energy.This has just influenced the utilization efficiency of concrete pump widely.
In order to improve the working life of wear ring, human abrasion resistance alloy casting wear-resistant ring is arranged, perhaps on the matrix of steel, use wear resistance electrode build-up wear-resistant layer, but the effect of these two kinds of methods is all significantly little with the method for built-up welding.On this basis, the someone utilizes cemented carbide to be welded on the main wear-resistant surface of wear ring, on less important wear-resistant surface again with the wear resistance electrode built-up welding to improve its working life.Though this method can improve the working life of wear ring to a certain extent, but still there is the unmatched problem of wear resistance.Its main wear-resistant surface adopts cemented carbide to make wearing layer, wear resistance can improve greatly, and less important wear-resistant surface is not inessential, it is bearing impact load, shear load and concrete washing away, because the difference of material behavior, the wear resistance of the wearing layer on the less important wear-resistant surface is far away less than the cemented carbide on the main wear-resistant surface.Although it is light that the wearing and tearing on the less important wear-resistant surface are wanted, the wearing layer on the less important wear-resistant surface is still destroyed early, has just caused the lip-deep wearing layer of groundwork to lose efficacy.
Summary of the invention: the utility model purpose is to solve that main wear-resistant surface does not match with less important wear-resistant surface wear resistance and the problem that causes main wearing layer inefficacy.
The wear ring that the utility model provides with cemented carbide wearing face, comprise the wear ring matrix of making by plain carbon steel, wearing layer in matrix surface and the matrix on the discharging hole wall, it is characterized in that the main wearing layer cemented carbide sector end-to-end looping wearing layer on the matrix surface, joint, sector two ends is the broken line that head and the tail cooperate, the first step outer round surface at the main wear-resistant surface of matrix place is positioned at the sector below and is combined into annular with the horminess fastening gold bar block end-to-end, and the wearing layer on the discharging hole wall is the annular that is combined into by cemented carbide Z type thin slice end-to-end.
The utility model advantage: 1, all wear-resistant surfaces of this wear ring all adopt the Hardmetal materials of different geometries, heterogeneity, make that the wear-resisting property at each position obtains overall matching on the wear ring, and the unlikely early stage problem of damaging in certain position that occurs; 2, Z type or camber sector, Z matrix, stick all belong to basic block, and these basic blocks can be formed size, different wear ring, make manufacturing become very convenient; 3, different parts not only can be selected difform basic block for use, these basic blocks can also be selected for use the cemented carbide of different components, with realization " using the best steel to make the knife's edge ", thereby has good economic feasibility; 4, the mechanical property at each position coupling on the wear ring, obtain prolonging overall working life; 5, select Z type sector and Z matrix for use, can prevent from concretely to wash away, extruding of mortar reveal and improve sealability.

Embodiment
As shown in the figure, this wear ring, comprise the wear ring matrix of making by plain carbon steel 1, wearing layer in matrix surface and the matrix on the discharging hole wall, it is characterized in that the main wearing layer cemented carbide sector 2 end-to-end looping wearing layers on the matrix surface, joint, sector two ends is the broken line that head and the tail cooperate, the first step outer round surface at the main wear-resistant surface of matrix place is positioned at the sector below and is combined into annular with horminess fastening gold bar block 3 end-to-ends, and the wearing layer on the discharging hole wall is the annular that is combined into by cemented carbide Z type thin slice 4 end-to-ends.
Wherein, why the cemented carbide joint on the main wear-resistant surface selects broken line for use, and its main purpose is exactly to prevent extruding of mortar, improves sealing.On less important wear-resistant surface, about two surfaces are made up of Z matrix and arc strip respectively, to improve the ability that anti impulsion load, shear load and concrete wash away.
