Abstract
A cutting loop with an abrasion resistant periphery and a long service life for the concrete delivery pump comprises a cutting loop body. Abrasion resistant welding is provided on the inner periphery of the cutting loop body in a surfacing welding way. The cutting loop body working face is welded with alloy rings in an embedding way or with abrasion resistant welding in a surfacing welding way. Alloy granules or alloy sheets or alloy blocks are embedded in the upper part of the cutting loop body periphery the rest part of which is provided with abrasion resistant welding in a surfacing welding way. The utility model has the characteristics of durability, abrasion resistance, impact resistance, prolonged-by-times service life, labor intensity decrease, equipment technical performance improvement and production efficiency increase.
Description
Technical field
The utility model relates to the constructional engineering machinery technical field, is specifically related to a kind of concrete pump cutting ring.
Background technique
The construction of engineerings such as tall building, dam, airport, tunnel, broken away from already now carry on the shoulder, the car handling send concrete method, and adopt concrete pump to carry, after the wear-out part cutting ring employing iron-base hard alloy material of people in 1999, improved 8-10 its working life doubly to transfer pump.But development along with building industry, particularly the construction of the tall building more than 100 meters and cement grade bring up to 100～120 from 30～50, the wearing and tearing of wear-out part cutting ring are accelerated, the average use will be changed in one, two day, the shortening in cutting ring working life might cause the concrete gambling plug of up to a hundred meters conveyance conduits, and its dismounting maintenance work difficulty is well imagined, increase labor intensity greatly, directly influenced construction speed and working efficiency.At present, the concrete pump of tall building need strengthen this technical barrier of propelling pressure, because pump king's invention and manufacturing, achieve a solution, but the quick loss of wear-out part pumping hole cutting ring has become the technical barrier of tall building concrete pump proper functioning, and this technical barrier ubiquity at home and abroad.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of durable wear, shock resistance are provided, the concrete pump that increases the service life, reduce labor intensity, improve Technical properties of plant and manufacturing efficiency at double is with the wear-resisting long lifetime cutting ring of periphery.
The technical solution adopted in the utility model is: this concrete pump wear-resisting long lifetime cutting ring of periphery; has the cutting ring body; all build-up wear-resistant welderings in the cutting ring body; cutting ring body working surface welding-on alloy hoop or build-up wear-resistant weldering; alloy granule or alloy slice or alloy block are inlayed in cutting ring body periphery top, the weldering of cutting ring periphery remaining part build-up wear-resistant.
In the technique scheme, build-up wear-resistant weldering on the cutting ring body working surface in the alloy hoop outside.
In the technique scheme, alloy granule is many.
In the technique scheme, alloy slice is a multi-disc, and alloy block is a polylith.
Role was during concrete pump was worked at the scene with cutting ring: connect, swing, between the diplopore of glasses plate, constantly replace, constantly send discharge to guarantee concrete, in running, week is even friction wear in the cutting ring, periphery is then in swinging, not only be subjected to the friction wear of surrounding concrete, but also to be subjected to concrete impact force, this has increased the wearing and tearing to the cutting ring periphery undoubtedly, and the wearing and tearing of periphery are not uniform: the one, and the cutting ring bigger position quick abrasion of power that is hit; The 2nd, plane that cutting ring combines with glasses plate and external diameter be quick abrasion from top to bottom.
The cutting ring of conventional art, all build-up wear-resistant layers in it, the thick carbide ring of 6～10mm is inlayed in the centre, and the alloy width is generally 15mm, the wear-resisting layer of the outer coating of alloy hoop.Have under the working condition of impact force, outer wear-resisting layer is worn very soon, extends to the bottom of periphery from planar point, after the wearing layer wearing and tearing, and the steel body region between the alloy rapidly weares and teares, and concrete begins to contact with middle carbide ring, and widens exposed layer gradually.Because it is cemented carbide and steel body are to adopt brazing solid mutually, form two splits, approaching or during above the thickness of cemented carbide when the height of exposed layer, cemented carbide holds can't stand impact and strong frictional force, go out ready-made section the piece that collapses soon, cause leak, spillage, can't work.Tall building transmission and concrete transmission pressure increases, impact force increases, add the raising of cement grade, the wearing and tearing of cutting ring external diameter have further been accelerated, make the disposable life-span of cutting ring only quantity delivered be about 500 cubes, so often will change one time cutting ring in one day, greatly influence construction speed and working efficiency.The carbide ring that also has a kind of conventional art cutting ring to inlay adopts " 7 " font structure, and its outer side of carbide ring of this " 7 " font structure is higher than former alloy plane of inlaying, thereby can improve antiwear property.But because: 1, when carrying out the brazing connection, be difficult to guarantee that its 90 ° of continuous braze layers are full, occur lacking the fragile imaginary point of copper easily; Though 2, cemented carbide hardness height holds and can't stand superpower impact force, particularly because the increase of the discharge pressure tenfold of transfer pump, impact force is bigger, and the result is that the fragility of cemented carbide is just more outstanding.In use machine have more than is needed a few minutes on one often, alloy is just disconnected broken.
The utility model adopts cutting ring body periphery top to inlay layer strengthening structure that add of alloy granule or alloy slice or alloy block.This is because cemented carbide is a kind of high abrasion resisting material, but its fragility is well-known shortcoming, makes it limit using scope, but granular alloy, but can bear bigger impact force as ball profile of tooth alloy, with mining button bit is example, and its alloy granule can not only taking up wear, and can bear high-frequency impact and rotation, when impacting rotation, also will pulverize rock, its working condition is more than the work under bad environment of cutting ring, but still the damage of bursting apart seldom occurs.Therefore, the utility model tumbles in circle or a few circle alloy granule or an alloy slice or an alloy block on cutting ring body periphery top, improved shock-resistant ability greatly, and its wear-resisting property is higher than the overlay cladding of wear-resisting weldering far away.
The utility model not only can be captured the technical barrier that the disposable conveying of tall building concrete puts in place more than 100 meters, satisfy pump king's requirement, and can prolong the working life of cutting ring exponentially, and comprise under common, the specific conditions, all can prolong the working life of cutting ring greatly.The utility model improves work efficiency more than 5 times for the disposable conveying that puts in place of tall building concrete more than 100 meters, and prolong more than 2 times the working life of cutting ring under the usual terms.
