Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model,, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
According to an aspect of the present utility model, a kind of cutting ring is provided, and this cutting ring comprises wear ring 1, it is characterized in that, described wear ring 1 is spelled knot by a plurality of Z-shaped wear-resistant blocks 2 or a plurality of T shape wear-resistant block 6 and is formed, and along the radial shape of described wear ring 1, becomes the seam of bending.
According on the other hand of the present utility model, a kind of concrete pumping equipment is provided, wherein, this concrete pumping equipment comprises cutting ring of the present utility model.
In the utility model, can be easily by spelling, tying cross section is the wear ring 1 that T shape wear-resistant block 6 that Z-shaped Z-shaped wear-resistant block 2 or cross section are T shape forms ring-type.Wherein, Z-shaped wear-resistant block 2 and T shape wear-resistant block 6 are the miniature parts of small volume, are convenient to processing, manufacture.Wherein, wear-resistant block of the present utility model can be made by the material of high strength, high wear resistance, to form the wear ring of high strength, high abrasion, thereby can bear and release work in suffered impulsive load.For example, can form by hard alloy blocks compacting sintering, and due to small volume, thereby the internal stress producing in sintering process is less and be easy to discharge and eliminate, make the wear-resistant block made not easily broken, and guaranteed to spell the hardness of the wear ring 1 that knot forms.
In addition, while spelling knot by Z-shaped wear-resistant block 2 or T shape wear-resistant block 6, along wear ring 1, radially can form the seam of bending.Even if joint filler produces groove in using process because of wearing and tearing, this groove is also not easy the seam expansion along bending, thereby can not form the groove that connects whole seam, can not form the groove that radially runs through wear ring 1 along wear ring 1.Therefore, wear ring 1 of the present utility model can guarantee that cutting ring has good sealing and working life.
Fig. 5 to Fig. 8 has shown the mode of execution of spelling knot wear ring 1 with Z-shaped wear ring 2.Wherein, each Z-shaped wear ring 2 has identical size, and the top margin of each Z-shaped wear ring 2 forms the outer circumferential face of wear ring 1, and base forms the inner peripheral surface of wear ring 1.
Fig. 9 to Figure 12 has shown the mode of execution of spelling knot wear ring 1 with T shape wear-resistant block 6.Wherein, described T shape wear-resistant block 6 comprises a T shape wear-resistant block 6a and the 2nd T shape wear-resistant block 6b that is adjacent to successively spell knot, and along described wear ring 1 radially, a described T shape wear-resistant block 6a and the 2nd T shape wear-resistant block 6b are inverted each other.Thus, the outer circumferential face of wear ring 1 is formed by the horizontal edge of a T shape wear-resistant block 6a and the vertical edge of the 2nd T shape wear-resistant block 6b, and the inner peripheral surface of wear ring 1 is formed by the horizontal edge of the 2nd T shape wear-resistant block 6b and the vertical edge of a T shape wear-resistant block 6a.
In addition, described cutting ring comprises ring-type matrix 3, and described wear ring 1 is arranged in the operative end surface of described ring-type matrix 3.And described cutting ring can comprise inner peripheral surface and the first wearable overlay 4 on outer circumferential face and the second wearable overlay 5 that is separately positioned on described ring-type matrix 3.As shown in Fig. 5, Fig. 7, Fig. 9, Figure 11, described the first wearable overlay 4, the second wearable overlay 5 are concordant with the end face of wear ring 1, and form together the sealed working face of described cutting ring.
In addition, cutting ring of the present utility model can be jacket-type, as shown in Fig. 5 and Fig. 9; Also can be built-in type, as shown in Fig. 7 and Figure 11.
In the utility model, can first splice Z-shaped wear-resistant block 2 or T shape wear-resistant block 6, then in the seam of wear-resistant block, fill scolder, thereby form seam by welding, and obtain wear ring 1.Then, wear ring 1 can be welded in the operative end surface of ring-type matrix 3.Finally, the first wearable overlay 4 and the second wearable overlay 5 are piled on the inner peripheral surface and outer circumferential face that is soldered to cyclic group body 3 respectively.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
