Abstract
The utility model provides a cutting ring of a composite layer structure. The cutting ring of the composite layer structure comprises a cutting ring body, and is characterized in that an inner overlaying layer is arranged on the inner lateral wall of the cutting ring body, an outer overlaying layer is arranged on the outer lateral wall of the cutting ring body, a concave groove is formed in the middle of the upper end of the cutting ring body, a diamond layer is arranged in the concave groove in a filling mode, and the upper ends of the diamond layer, the inner overlaying layer, the outer overlaying layer and the cutting ring body are level with each other. The cutting ring of the composite layer structure fits a glass plate more tightly when used and prevents ventilation. Meanwhile, the diamond layer can reinforce the abrasion resistance of a cutting fitting surface of the cutting ring, and therefore the service life of the cutting ring is effectively prolonged.
Description
Technical field
The utility model relates to a kind of cutting ring for concrete pumping machinery equipment, particularly discloses a kind of cutting ring of lamination layer structure.
Background technique
Concrete pumping machinery equipment is for closely carrying the large-scale complete automation equipment of fresh concrete, can be by slump concrete conveyance within limits to certain altitude or carry out the horizontal feed of certain distance, be widely used in the job site of the big-and-middle-sized Infrastructure such as city business's concrete, railway, road, bridge, dam, airport, harbour.Wherein, cutting ring is the vital part of concrete pumping machinery equipment pumping system.
But, mainly there is the problem of following three aspects in the cutting ring that existing concrete pumping machinery equipment pumping system adopts: first, the working life that is cutting ring is generally shorter, affects the pumping capacity of concrete pumping machinery equipment, causes capacity utilization to reduce; The second, be that the face that suits of cutting ring and glasses plate exists certain gap, easily extraneous air to be brought in conveyance conduit, the concrete that causes carrying is easily emanated, concrete slump does not reach the Quality Down problems such as requirement; The 3rd, be that the wearing and tearing that suit face of cutting ring and glasses plate are very fast and serious, cause cutting ring user cost higher.
Summary of the invention
The purpose of this utility model is to solve problems of the prior art, a kind of high life is provided, suits tightr, to have the lamination layer structure of high wear resistance cutting ring.
The utility model is achieved in that a kind of cutting ring of lamination layer structure, comprise cutting ring body, it is characterized in that: the madial wall of described cutting ring body is provided with interior overlay cladding, the outer side wall of described cutting ring body is provided with outer overlay cladding, in the middle of the upper end of described cutting ring body, be provided with groove, in described groove, fill out and be provided with diamond layer, each upper end of described diamond layer, interior overlay cladding, outer overlay cladding, cutting ring body flushes.
Described diamond layer is connected with described groove by the mode of welding or adhesion.
Described cutting ring body is connected as a single entity and is formed by upper ring and lower ring, described pressed on ring is identical with the internal diameter of lower ring, the external diameter of described lower ring is less than the external diameter of pressed on ring, the height of described interior overlay cladding is less than or equal to the height of described cutting ring body and is greater than the height of described pressed on ring, and described outer overlay cladding is positioned on the outer side wall of described pressed on ring.
The beneficial effects of the utility model are: owing to being provided with diamond layer in cutting ring body, the outstanding advantages such as diamond layer has high wear resistance, high hardness, rigidity is good, quality is light, when the utility model and glasses plate are used in conjunction with, because the shape of cutting ring body reduces its surface friction drag suiting between face, therefore, can guarantee that suiting of the utility model and glasses plate is tightr, prevent ventilative, simultaneously, diamond layer also can strengthen the wear resistance that cutting ring suits face, thereby effectively improves the working life of cutting ring.
Accompanying drawing explanation
Fig. 1 is the utility model cross section structure schematic diagram.
Fig. 2 is the structural representation of the utility model cutting body.
Fig. 3 is the utility model plan structure schematic diagram.
Wherein: 1, cutting ring body; 2, interior overlay cladding; 3, outer overlay cladding; 4, groove; 5, diamond layer; 6, pressed on ring; 7, lower ring.
Embodiment
According to Fig. 1, Fig. 2, Fig. 3, the utility model comprises cutting ring body 1, the madial wall of described cutting ring body 1 is provided with interior overlay cladding 2, the outer side wall of described cutting ring body 1 is provided with outer overlay cladding 3, in the middle of the upper end of described cutting ring body 1, be provided with groove 4, in described groove 4, fill out and be provided with diamond layer 5, described diamond layer 5 is connected with described groove 4 by the mode of welding or adhesion.Each upper end of described diamond layer 5, interior overlay cladding 2, outer overlay cladding 3, cutting ring body 4 flushes.Described cutting ring body 1 is connected as a single entity and is formed by pressed on ring 6, lower ring 7, described pressed on ring 6 is identical with the internal diameter of lower ring, the external diameter of described lower ring 7 is less than the external diameter of pressed on ring 6, the height of described interior overlay cladding 2 is less than or equal to the height of described cutting ring body 1 and is greater than the height of described pressed on ring 6, and described outer overlay cladding 3 is positioned on the outer side wall of described pressed on ring 6.The total height of described pressed on ring 6, lower ring 7 is the height of described cutting ring body 1.
Because cutting ring is normally used in conjunction with glasses plate, the face that suits is between the two annular contact surface, in order to prevent that the face that suits of the utility model cutting ring and glasses plate from producing in the course of the work excessive gap and causing ambient air to enter in conveyance conduit, the concrete quality that impact is carried, must guarantee to suit after cutting ring is connected with glasses plate the cooperation tightness of face, therefore, described diamond layer 5 is to be circular, and its width evenly and be no more than described cutting ring body 1 width; In addition, each upper-end surface of described diamond layer 5, interior overlay cladding 2, outer overlay cladding 3, cutting ring body 4 flushes, and can guarantee to suit surface wear in the utility model using process even, increases the wear-out period, thereby extends the working life of cutting ring.
Because the utility model is the pumping system for concrete pumping machinery equipment, working load is large, working environment is also more severe, in order to guarantee the continuity of construction operation, guarantee the pumping capacity of concrete pumping machinery equipment, must guarantee the soundness of described diamond layer 5, therefore, can will between diamond layer 5 and the groove 4 of cutting ring body 1, by welding manner, be consolidated into one, diamond layer 5 is cemented in described cutting ring body 1.Certainly, if the pumping capacity of concrete pumping machinery equipment is less demanding, also can diamond layer 5 and cutting ring body 1 be consolidated into one by strength adhesive, diamond layer 5 is firmly cemented in the groove 4 of described cutting ring body 1.In order to facilitate the installation of the utility model on concrete pumping machinery equipment, the floor height that covers the interior overlay cladding 2 on cutting ring body 1 madial wall is greater than the height of the outer overlay cladding 3 that covers described cutting ring body 1 outside.
