Abstract

The invention discloses a kind of wear-resisting combination filling pipe of ellipse, belong to mining machinery;Aim to provide that a kind of tube wall is nonabradable wear-resisting compound to fill delivery pipe.It includes outer tube, the internal lining pipe being fixed in the outer tube;Outer tube(1)External surface top and bottom have respectively along generatrix direction be distributed first flag line(4)With second identifier line(5), the internal lining pipe is by multistage outer surface is rounded, inner surface is oval inner tube(2)Docking forms, in each section of inner tube(2)Outer surface on correspond to ellipse short shaft position have along generatrix direction be distributed the 3rd tag line(6);3rd tag line and first flag line(4)Or second identifier line(5)Position correspondence.The present invention not only substantially prolongs the usage time of conveyance conduit, reduce the frequency for replacing pipeline, but also also saves pipeline purchase and maintenance cost, can ensure that filling engineering is worked continuously, and improves construction efficiency;It is a kind of slurry transport lines improved structure.

Description

The wear-resisting combination filling pipe of ellipse
Technical field
The present invention relates to a kind of slurry transport lines, more particularly to a kind of oval wear resistant conveying pipe, belong to mining machinery Equipment.
Background technology
It is well known that needed when being filled processing to mine worked-out section by pipeline to goaf long distance delivery sand Slurry.Due to the effect of gravity, the latter half of tube wall be easily subject to the particle fast flush in mortar and wear it is thinning, even let out Leakage, need to often replace pipeline.It is not only of high cost, but also filling construction operation can be caused to interrupt.In order to save piping cost, lead to The normal practice is will to be exchanged at the top and bottom of pipeline into row position, then proceed to use.This method is although fairly simple and can Extend the service life of pipeline, but must frequent shutdown maintenance, influence construction speed.
The content of the invention
In view of the above defects of the prior art, the present invention is intended to provide a kind of nonabradable ellipse of tube wall is resistance to Grind combination filling pipe.
To achieve these goals, the present invention uses following technical scheme:It include outer tube, be fixed on it is interior in the outer tube Bushing pipe;The first flag line and second identifier line being distributed along generatrix direction are arranged respectively at the external surface top of outer tube and bottom, described Internal lining pipe is formed by the inner tube docking that multistage outer surface is rounded, inner surface is oval, right on the outer surface of each section of inner tube Should in the position of ellipse short shaft have along generatrix direction be distributed the 3rd tag line;3rd tag line and first flag line or second Tag line position correspondence.
The positioning tooth of city wall stacking structure is distributed with the both ends of the surface of each inner tube;Correspond to first flag on the inner wall of outer tube There is the guide groove opened up along generatrix direction in the position of line or second identifier line, and it is short that the ellipse is corresponded on the outer wall of each inner tube The position of axis is equipped with the feather key being adapted with the guide groove.
Compared with the prior art, the present invention in common conveyance conduit by adopting the above-described technical solution, add one The oval internal lining pipe of root inner surface, therefore substantially prolongs the usage time of conveyance conduit, reduce the frequency for replacing pipeline Rate, had not only saved pipeline purchase and maintenance cost but also can guarantee that filling engineering is worked continuously, and improved construction efficiency.
Brief description of the drawings
Fig. 1 is the structure diagram of the embodiment of the present invention;
Fig. 2 is the A-A sectional views in Fig. 1;
Fig. 3 is sectional view of the another embodiment of the present invention at A-A.
In figure:Outer tube 1, inner tube 2, positioning tooth 3, first flag line 4, second identifier line 5, the 3rd tag line 6, feather key 7.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 2:The first flag line 4 and second being distributed along generatrix direction is arranged respectively at the external surface top of outer tube 1 and bottom Tag line 5, is fixed with internal lining pipe in outer tube 1.The internal lining pipe is by multistage outer surface is rounded, inner surface is oval inner tube 2 Docking forms, and there is the 3rd mark along generatrix direction distribution in the position corresponding to ellipse short shaft on the outer surface of each section of inner tube 2 Line 6;3rd tag line and 5 position correspondence of first flag line 4 or second identifier line.
Embodiment 2
In order to ensure each section of inner tube 2 dock after can coaxially, so as to avoid each section of docking dislocation of inner tube 2, in basic structure and reality Apply example 1 it is identical on the basis of the present invention can also use structure as shown in Fig. 1~2:City wall is distributed with the both ends of the surface of each inner tube 2 The positioning tooth 3 of stacking structure, adjacent inner tube 2 are positioned by positioning tooth 3 and docked.
Embodiment 3
In order to ensure each section of inner tube 2 dock after can coaxially, and also to easy to assemble, in basic structure and 1 phase of embodiment The present invention can also use structure as shown in Figure 3 with the basis of:Corresponding to first flag line 4 on the inner wall of outer tube 1 Position, which has along generatrix direction, opens up guide groove(Do not indicated in figure), ellipse short shaft or the are corresponded on the outer wall of each inner tube 2 The position of three tag lines 6 is equipped with the feather key 8 being adapted with the guide groove.
In use, when the tube wall in thickness in inner tube 2(With the oval corresponding tube wall of the latter half short axle)Be worn change Bao Hou, only need to rotate 180 degree using axis as the center of circle by the present invention(Make second identifier line 5 in upper, first flag line 4 under), so After be continuing with.
