Abstract

The utility model relates to a wear-resisting plate and wear-resisting ring for a concrete delivery pump, which comprises the basal body of the wear-resistant plate, the basal body of the wear-resistant ring, and a wear-resistant layer positioned on the surface thereof. The wear-resistant layer is a hard alloy strip layer which is sintered under high temperature and is fixed on the surface of the basal body in interval arrangement. A metal filler is arranged between the hard alloy for adsorbing impact energy. The wear-resisting plate has the advantages of good wear-resisting property, long service life, less shutdown times, repair man-hour fee, less waste, low cost, and high delivery efficiency and can simultaneously adsorb the impact energy for avoiding the brittle failure of hard alloy; compared with the general wear-resistant plate and the general wear-resistant ring for conveying concrete, the utility model can increase number by multiple times.

Description

Concrete pump is with wearing plate and wear ring

The utility model belong to building machinery particularly the concrete pump accessory be wearing plate and wear ring.

Wearing plate and wear ring are crucial component in the concrete pump, also are easily damaged partss.Wearing plate in the concrete pump, ring are mostly by wear resistance electrode built-up welding and abrasion resistance alloy casting at present, its life-span is shorter, in case occur losing efficacy because of wearing and tearing, then must termination of pumping change, surpass 4 hours as the replacing time, then concrete will initial set occur and can not re-use, bring great inconvenience and waste to construction like this, sometimes in order to prevent termination of pumping midway, the wearing plate, the ring that are about to as yet not wearing and tearing fully and can not finish one deck cast before cast are changed, and cause unnecessary waste.

The utility model purpose provides the good long service life of a kind of wear-resisting property and can absorb the concrete pump wearing plate and the wear ring of impact energy.

This novel wearing plate that provides comprises the wearing plate matrix that has two holes on it, wearing layer on matrix surface and the hole inwall, the wearing layer that it is characterized in that matrix surface is that high temperature sintering or inlay is fixed on the matrix surface and spaced horminess fastening gold bar block layer, is the metal charge of high temperature sintering absorbed impact energy betwixt between horminess fastening gold bar block.

Comprise the wear ring matrix with the matching used wear ring of wearing plate, wearing layer on matrix surface and the wear ring matrix inner hole wall, the wearing layer that it is characterized in that matrix surface is that high temperature sintering or inlay is fixed on the matrix surface and spaced horminess fastening gold bar block layer, and cemented carbide gold bar interblock is the metal charge of high temperature sintering absorbed impact energy betwixt.

Advantage of the present utility model: 1. owing to adopt ultrahigh hardness and spaced horminess fastening gold bar block to do wearing layer, make its hardness very high even also higher than the hardness of the ash in the concrete, sand, stone, therefore the wearing and tearing that can resist abrasive particle effectively, wear-resisting property is provided greatly, increase the service life, the quantity of its delivering concrete is improved more than the several times than common wearing plate, ring, reduced the shutdown number of times, maintenance man-hours and expense have been reduced, reduced waste, reduce cost, improved the efficient of delivering concrete greatly; 2. the metal charge between horminess fastening gold bar block is low than cemented carbide hardness, and is flexible good, can absorb impact energy well, prevents the brittle failure of cemented carbide; 3. fixedly horminess fastening gold bar block and matrix of high temperature sintering makes its more common welding fixed deformation little, do not ftracture, and hardness alloy and matrix is bonding firmly evenly.

The utility model embodiment accompanying drawings is as follows:

Fig. 1. the wearing plate schematic representation;

Fig. 2. the wear ring schematic representation.

Wearing plate as shown in Figure 1, comprise the wearing plate matrix 1 that has two holes on it, body upper surface adopts high-temperature sintering process to be fixed with the spaced horminess fastening gold bar block 2 of one deck and forms wearing layer 3, between horminess fastening gold bar block, be fixed on therebetween metal charge 4 for high temperature sintering, this metal can be a copper, manganese, iron, the alloy that nickel etc. are arbitrarily made with also can be dosed Tungsten carbite to improve wear-resisting property, because this metal hardness is low than the hardness alloy, flexible good, can absorb impact energy well, reduce the cemented carbide brittle failure, the hole inwall can be used abrasion resistance alloy, or the copper ferromanganese adds Tungsten carbite and does wearing layer.

Fig. 2. for the matching used wear ring of Fig. 1 wearing plate, comprising wear ring matrix 5, horminess fastening gold bar block 2 be spaced and high temperature sintering on matrix, be metal charge 4 between horminess fastening gold bar block, wearing layer 3 and wearing plate are identical on the wear ring.Cemented carbide and wearing plate cyclic group body weld together it by the bonding effect of metal penetration and metal charge securely under high temperature condition.During the transmission and concrete transmission pump work, wear ring crisscross motion between two holes on wearing plate surface reaches the delivering concrete purpose.

Claims

1. concrete pump wearing plate, comprise the wearing plate matrix that has two holes on it, wearing layer on matrix surface and the hole inwall, the wearing layer that it is characterized in that matrix surface is that high temperature sintering or inlay is fixed on the matrix surface and spaced horminess fastening gold bar block layer, is high temperature sintering absorbed impact energy metal charge betwixt at hard alloy bar interblock.

One kind with the matching used wear ring of the described wearing plate of claim 1, comprise the wear ring matrix, wearing layer on matrix surface and the wear ring matrix inner hole wall, the wearing layer that it is characterized in that matrix surface is that high temperature sintering or inlay is fixed on the matrix surface and spaced horminess fastening gold bar block layer, is the metal charge of high temperature sintering absorbed impact energy betwixt between horminess fastening gold bar block.
