Abstract

The utility model relates to a carbide wear plate and wear ring of the concrete transfer pumps, comprising a wear plate base with two round holes and a wear ring base with one round hole. The wear layer on the bases is made up of a plurality of circle blocks, which are made by sintering cemented carbide material with high temperature on the bases. The cemented carbide material circle blocks on the bases arrayed form a two circle structure; the straight slots between the cemented carbide material circle blocks of the inner and the outer circles are stagger. Eighteen to twenty four cemented carbide material circle blocks are arranged on each of the inner and the outer circle. The utility model has the advantages that: the wear resistant performance and service life are greatly improved; the embrittlement defect of cemented carbide material is conquered, for the surface of each cemented carbide material block is small; the slurry can not be leaked when pumps concrete and the water also can not be leaked when the pump is washed; the welding is firm and the impulsive force is absorbed.

Description

Concrete pump cemented carbide wearing plate and wear ring

Technical field

The utility model belongs to building machinery concrete pump accessory, particularly a kind of concrete pump cemented carbide wearing plate and wear ring.

Background technique

Wearing plate and wear ring are crucial component in the concrete pump, it also is easily damaged parts, wearing plate in using at present, the ring major part is by wear resistance electrode built-up welding or abrasion resistance alloy casting, its life-span is short, must termination of pumping change in case wearing and tearing occur, so just brought inconvenience and waste to construction.

Summary of the invention

It is good that the purpose of this utility model provides a kind of wear-resisting property, and long service life is not run slurry during pumping, watertight concrete pump cemented carbide wearing plate and wear ring when washing pump.

The technical solution of the utility model is: a kind of concrete pump cemented carbide wearing plate and wear ring, comprise wearing plate matrix that has two circular holes on it and the wear ring matrix that has a circular hole, the wearing layer of matrix surface is characterized in that: the wearing layer of matrix surface is the sector unit composition that is connected the Hardmetal materials on the matrix with high temperature sintering.

The sector unit of the Hardmetal materials on the matrix rearranges twin nuclei, and the vertical masonry joint between the sector unit of the adjacent Hardmetal materials on the internal and external double-circular staggers mutually.

The sector unit 18-24 piece that Hardmetal materials is arranged on the every ring on the internal and external double-circular.

The utility model advantage: 1, owing to adopted ultrahigh hardness and wear-resisting Hardmetal materials, its hardness, abrasion resistance is higher than ash, sand, the stone hardness in the concrete, and the wearing and tearing that therefore can resist abrasive particle effectively improve wear-resisting property greatly, greatly increase the service life.2, because every ring adopts 18-24 piece sector unit, thereby reduced the cemented carbide single-block area, this just overcomes the shortcoming of the easy embrittlement of cemented carbide to fall.3, because dicyclo has been made in discharging, the vertical masonry joint that staggered makes wearing plate and wear ring sealability better, thereby has accomplished, does not run slurry during pump concrete, during the washing pump, does not metal run out.4, owing to use the high temperature sintering technology, cemented carbide and matrix are organically bonded together, thereby make firm welding, also absorbed impact force.In sum: owing to adopted its high hardness of Hardmetal materials, and wear resistance, suitable cemented carbide single-block area is avoided embrittlement, the dicyclo structure of the vertical masonry joint that staggers and the technology of employing high temperature sintering, make wearing plate and wear ring, improved wear resistance greatly and prolonged working life, making its delivering concrete quantity is common plate, number of rings doubly more than, reduce the pumping cost, improved manufacturing efficiency greatly.

Embodiment

Wearing plate as shown in Figure 1, comprise the wearing plate matrix 1 that has two circular holes on it, it is neat that body upper surface adopts high-temperature sintering process to be fixed with one deck discharging, the vertical masonry joint that staggers becomes cemented carbide sector unit 2, formation wearing layer 3, the hole inwall of dicyclo shape can use cemented carbide, or wear resistance electrode is done wearing layer 4.

Fig. 2, be and the matching used wear ring of Fig. 1 wearing plate, it is neat to adopt high-temperature sintering process to be fixed with one deck discharging comprising wear ring matrix 5 matrix surfaces, the vertical masonry joint that staggers become the dicyclo shape cemented carbide sector unit 2, form wearing layer 3.Wear-resisting annular distance inwall, the ring outer wall can be done wearing layer 4 with cemented carbide or wear resistance electrode.During the transmission and concrete transmission pump work, wear ring crisscross motion between two holes on wearing plate surface is to reach the delivering concrete purpose.
