Description
Technical field
The present invention relates to a kind of fluid-conveying pipe, more particularly to a kind of eccentric wear resistant conveying pipe, belong to mine mechanism.
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 bias of tube wall is wear-resisting
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 external surface top of outer tube have along generatrix direction be distributed first flag line, the internal lining pipe by multistage upper tube wall it is thin, under
The eccentric pipe docking of thickness of pipe wall forms, and the external surface top of each section of eccentric pipe has the second identifier line being distributed along generatrix direction；The
One tag line is corresponding with second identifier line position.
The positioning tooth of city wall stacking structure is distributed with the both ends of the surface of each eccentric pipe；Correspond to the first mark on the inner wall of outer tube
There is the guide groove opened up along generatrix direction in the position for knowing line, and the position corresponding to second identifier line on the outer wall of each eccentric pipe is set
There is 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
Root top half tube wall is thin, the eccentric internal lining pipe of the latter half thickness of pipe wall, thus substantially prolongs conveyance conduit usage time,
The frequency for replacing pipeline is reduced, pipeline purchase and maintenance cost had not only been saved 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, eccentric pipe 2, positioning tooth 3, first flag line 4, second identifier line 5, feather key 6.
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 external surface top of outer tube 1 is equipped with the first flag line 4 being distributed along generatrix direction, is fixed with outer tube 1
Internal lining pipe.The internal lining pipe is by multistage top half tube wall is thin, the eccentric pipe of the latter half thickness of pipe wall 2 is docked and formed, each section of bias
The external surface top of pipe 3 has the second identifier line 5 being distributed along generatrix direction；First flag line 4 and 5 position pair of second identifier line
Should.
Embodiment 2
In order to ensure each section of eccentric pipe 2 dock after can coaxially, so as to avoid each section of docking dislocation of eccentric pipe 2, in basic structure
The present invention can also use the structure as shown in Fig. 1~2 on the basis of same as Example 1：The both ends EDS maps of each eccentric pipe 2
There is the positioning tooth 3 of city wall stacking structure, adjacent eccentric pipe 2 is positioned by positioning tooth 3 and docked.
Embodiment 3
In order to ensure each section of eccentric pipe 2 dock after can coaxially, and also to easy to assemble, in basic structure and embodiment 1
The present invention can also use structure as shown in Figure 3 on the basis of identical：Correspond to first flag line 4 on the inner wall of outer tube 1
Position have the guide groove opened up along generatrix direction, be equipped with the outer wall of each eccentric pipe 2 corresponding to the position of second identifier line 5
The feather key 6 being adapted with the guide groove.
