The low-cost long-life cutting ring for a concrete conveying pump is durable, has impact resistance property, has duplicated prolonged service life, reduces labor intensity and increases the equipment technical property and production efficiency.
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, increase the service life, reduce labor intensity, improve the concrete pump low-cost long-life cutting ring of Technical properties of plant and manufacturing efficiency at double.
The technical solution adopted in the utility model is: this concrete pump low-cost long-life cutting ring, has the cutting ring body, the weldering of cutting ring body inner periphery and the outer periphery build-up wear-resistant, cutting ring body working surface welding-on alloy hoop or build-up wear-resistant weldering, cutting ring body working surface is welding-on alloy circle also, the height of alloy circle connects with brazing between alloy hoop and the alloy circle greater than the height of alloy hoop.
In the technique scheme, build-up wear-resistant weldering on the cutting ring working surface in the alloy circle outside.
In the technique scheme, the alloy circle is made of whole circle or several sections alloy blocks.
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 the structure of the newly-increased alloy circle of welding-on, and the height of alloy circle is greater than the height of alloy hoop, be connected with brazing between alloy hoop and the alloy circle, like this, can absorb a part of stress on the one hand, certain buffer function is arranged on the other hand, avoid the alloy brittle failure, the increase of alloy circle makes cutting ring from the inwardly all wear processes of periphery, after the alloy circle wearing and tearing that must earlier the outside be increased, alloy hoop just can expose out, and the alloy circle that directly weares and teares needs a large amount of time, so just can avoid the plane alloy exposed too early, is prolonged the working life of cutting ring greatly.
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.
