Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
The invention provides a kind of flange assembly, as shown in Figure 2, comprise flange body 1 and the wear-resistant sleeve 2 that is arranged in the flange body 1, the port of these wear-resistant sleeve 2 one ends engages with the port of this flange body 1 endoporus, and the port of the other end engages with the hole wall of this flange body 1 endoporus.
The two ends of wear-resistant sleeve 2 engage with flange body 1 respectively, can make wear-resistant sleeve 2 and flange body 1 can relative displacement not occur axially, and means of fixation is more firm.In prior art in the past, wear-resistant sleeve 2 does not directly structurally engage with flange body 1 usually, therefore insecure with being connected of flange body 1, easily in transportation or installation process, cause wear-resistant sleeve 2 and flange body 1 to break away from, in use also easily owing to connecting the insecure low problem in working life that causes.Wear-resistant sleeve 2 among the present invention has solved this problem by the structure that two ends engage with flange body 1, and wear-resistant sleeve 2 is engaged with flange body 1 firmly, has also prolonged in addition the working life of flange assembly.
In order to further facilitate the fixing of wear-resistant sleeve 2 and flange body 1 port, be formed with ring ladder groove 14 in the port of flange body 1 endoporus.Ring ladder groove 14 has formed a fixedly spatial structure of wear-resistant sleeve 2 one end ports, and the port of wear-resistant sleeve 2 is fixed on the ring ladder groove 14, thereby wear-resistant sleeve 2 is fixed on the flange body 1; Certainly, in order to cooperate fully with the structure of ring ladder groove 14, can also make the port of wear-resistant sleeve 2 one ends have flange, flange engages with ring ladder groove 14.The turnup structure that wear-resistant sleeve 2 ports form has consisted of ring baffle, is fastened in the ring ladder groove 14, just in time catches in the axial direction ring ladder groove 14, makes wear-resistant sleeve can not break away from flange body 1; In addition, after the bending of the port flange of wear-resistant sleeve 2, can also solve wear-resistant sleeve 2 and the inequal problem of flange body 1 assembling rear port.
One end of wear-resistant sleeve is fixing by the ring ladder groove 14 of flange and flange body 1, the other end also needs to fix with the hole wall of flange body 1 endoporus, concrete means of fixation has multiple, and cooperatively interacting and could realize better fixing on the hole wall Structure of need of wear-resistant sleeve 2 and flange body 1 endoporus.Therefore, in one embodiment of the invention, can be set to following structure for the hole wall of flange body 1 endoporus:
As shown in Figure 2, be formed with the transition part 12 around the axle center of flange body 1 on the hole wall of flange body 1 endoporus, the hole wall of flange body 1 endoporus is from initial with ring ladder groove 14 intersections, extend axially along hole wall and to comprise successively initial part 11, transition part 12 and joint 13, the aperture of this joint 13 is greater than the aperture of this initial part 11.
The effect that transition part 12 is set is the sunk structure of hole wall formation at flange body 1 endoporus, when fixing wear-resistant sleeve 2, the structure of wear-resistant sleeve 2 the other ends and the sunk structure of transition part 12 are interfixed, make between wear-resistant sleeve 2 and the flange body 1 interfix easier; And joint 13 greater than the benefit of transition part 12 is, when concrete delivery pipe inserts joint, the thickness of concrete delivery pipe self tube wall can be contained in the structure of joint 13 apertures greater than initial part 12 aperture parts, the inwall of concrete delivery pipe is directly docked with the inwall of wear-resistant sleeve 2, make concrete resistance when carrying less.
Certainly, the structure that the structure of wear-resistant sleeve 2 can further be set to form in the hole wall with flange body 1 endoporus is complementary, and the other end of wear-resistant sleeve 2 is engaged with transition part 12 by enlarging.Like this, whole wear-resistant sleeve 2 is just fixed with flange body 1 respectively from two ends, can not break away from.
Further, as shown in Figure 1 and Figure 2, in the prior art, wear-resistant sleeve 2 ' wall thickness everywhere is identical, and when reality is used, very easily wear and tear in the port of wear-resistant sleeve 2 ', and the port wearing and tearing cause scrapping of whole wear-resistant sleeve.Therefore, in order to increase the thickness of wear-resistant sleeve 2 port position, the end face of flange is vertical with the inwall of this wear-resistant sleeve 2.Because wear-resistant sleeve 2 self has certain thickness, being equivalent to wear-resistant sleeve 2 ports behind the flange has increased thickness diametrically.Usually the position of processing flange can form arc-shaped curved surface at inwall outward place, and such structure can not play the effect of thickening port thickness, because curved-surface structure has only been realized bending.Therefore, also need further port to be processed into the end face structure vertical with inwall, eliminate curved surface, make the end face of wear-resistant sleeve 2 and two faces of inwall of wear-resistant sleeve 2 realize intersecting vertically, be equivalent to like this fill up the bending place of curved surface, make the bending place realize right angle intersection, thereby increased the thickness of wear-resistant sleeve 2 flange positions.
The other end of wear-resistant sleeve 2 engages by the inwall of enlarging with flange body 1, and therefore in order to make snap-in structure firm, as shown in Figure 3, the internal surface of transition part 12 forms the tapering curved surface around flange body 1 axle center.The tapering curved surface is the structure that internal diameter increases gradually, and 13 internal diameters increase progressively from initial part 11 to joint, and such as Fig. 6, shown in Figure 7, wear-resistant sleeve 2 is after enlarging, and the edge is stuck on the transition part 12, and wear-resistant sleeve 2 can not be moved to initial part 11 directions, thereby realizes being fixed.
Among the embodiment provided by the invention, as shown in Figure 4, the structure of transition part 12 can also be: transition part 12 forms step surface, and this step surface around and the vertical axle center of this flange body 1.The plane of namely transition part 12 formation is perpendicular to the inwall of initial part 11 and joint 13, from initial part 11 vertical transitions to joint 13.Plant therewith transition part 12 engagings of structure after wear-resistant sleeve 2 enlargings, can make the part of wear-resistant sleeve 2 enlargings catch on transition part 12, make snap-in structure more firm.
A kind of concrete conveying pipe also is provided in one embodiment of the present of invention, comprise concrete delivery pipe and flange assembly, flange assembly is the flange assembly in above-described embodiment, concrete delivery pipe docks with wear-resistant sleeve 2, and the part that flange body 1 exceeds wear-resistant sleeve 2 is socketed on the described concrete delivery pipe.
