The utility model discloses a kind of wear-resisting combination filling pipes of bias, belong to mining machinery；It is intended to provide a kind of nonabradable wear-resisting combination filling pipe of tube wall.It includes outer tube, the internal lining pipe being fixed in the outer tube；Outer tube（1）External surface top have the first flag line being distributed along generatrix direction（4）, the internal lining pipe by thin, the lower thickness of pipe wall of multistage upper tube wall eccentric pipe（2）It docks, each section of eccentric pipe（2）External surface top have the second identifier line being distributed along generatrix direction（5）；First flag line（4）With second identifier line（5）Position corresponds to.The utility model not only substantially prolongs the usage time of conveyance conduit, reduces 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
Technical field
The utility model is related to a kind of fluid-conveying pipe more particularly to a kind of eccentric wear resistant conveying pipes, belong to mining machinery
Equipment.
Background technology
It is well known that it is needed when being filled processing to mine worked-out section through pipeline to goaf long distance delivery sand
Slurry.Due to the effect of gravity, the lower half portion of tube wall easily worn by the particle fast flush in mortar 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 carry out position at the top and bottom of pipeline to exchange, and then proceedes to use.This method is although fairly simple and can
Extend the service life of pipeline, but must frequent shutdown repair, influence construction speed.
Invention content
In view of the above defects of the prior art, the utility model is intended to provide a kind of nonabradable bias of tube wall
Wear-resisting combination filling pipe.
To achieve these goals, the utility model uses following technical scheme：It includes outer tube, is fixed in the outer tube
Internal lining pipe；The external surface top of outer tube has the first flag line being distributed along generatrix direction, and the internal lining pipe is by multistage upper tube wall
The eccentric pipe of thin, lower thickness of pipe wall docks, and the external surface top of each section of eccentric pipe has the second identifier being distributed along generatrix direction
Line；First flag line is corresponding with second identifier line position.
The positioning tooth of city wall stacking structure is distributed in 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 utility model in common conveyance conduit by adopting the above-described technical solution, increase
A piece top half tube wall is thin, lower half portion thickness of pipe wall eccentric internal lining pipe, therefore substantially prolongs the use of conveyance conduit
Time reduces the frequency for replacing pipeline, had not only saved pipeline purchase and maintenance cost but also can guarantee that filling engineering is continuously made
Industry improves construction efficiency.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the A-A sectional views in Fig. 1；
Fig. 3 is the sectional view of the utility model another embodiment 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.
Specific embodiment
The utility model is described in further detail 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, consolidates in outer tube 1
Surely there is internal lining pipe.The internal lining pipe is by multistage top half tube wall is thin, eccentric pipe 2 of lower half portion thickness of pipe wall docks, each section
The external surface top of eccentric pipe 3 has the second identifier line 5 being distributed along generatrix direction；First flag line 4 and 5 position of second identifier line
It is corresponding.
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, basic
The utility model can also use the structure as shown in Fig. 1~2 on the basis of structure is same as Example 1：The two of each eccentric pipe 2
The positioning tooth 3 of city wall stacking structure is distributed in end face, and 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 convenient for assembling, in basic structure and implementation
The utility model can also use structure as shown in Figure 3 on the basis of example 1 is identical：Correspond to first on the inner wall of outer tube 1
There is the guide groove opened up along generatrix direction in the position of tag line 4, corresponding to second identifier line 5 on the outer wall of each eccentric pipe 2
Position is equipped with the feather key 6 being adapted with the guide groove.
