Abstract
The utility model discloses a kind of pile foundation concrete to pour into a mould the small reducer union that becomes larger of conduit, by setting both ends diameter inconsistent, the coupling tube that centre passes through canalis spinalis transition, the smaller one end of diameter is provided with externally threaded pin end, the one end being relatively large in diameter sets female female connector, collar nut is set outside female connector, it realizes and realizes the outlet caliber of the concrete hopper purpose consistent with blanking conduit caliber without conduit is needed to change, it is greatly saved the time required to replacing conduit, it is time saving and energy saving, substantially increase construction efficiency.
Description
Technical field
The utility model belongs to construction equipment technical field, and in particular to a kind of pile foundation concrete cast conduit is small
Become larger reducer union.
Background technology
In the conduit for often using different tube diameters as needed during existing pile foundation construction, when needing replacing caliber
The outlet caliber that must make concrete hopper is consistent with blanking conduit caliber, and when replacement needs crane cooperation lifting transfer, not only
It is time-consuming and laborious, and have an effect on integral construction efficiency.
In view of this, those skilled in the art are dedicated to a kind of nothing is set to need to change conduit to realize going out for concrete hopper
The pile foundation concrete cast small reducer union that becomes larger of conduit of the mouth caliber purpose consistent with blanking conduit caliber, it is existing to solve
Above-mentioned technical problem existing for technology is of great significance for improving construction efficiency.
Utility model content
The utility model needs crane cooperation lifting transfer when being directed to the replacement conduit of the prior art, not only time-consuming and laborious,
And the defects of having an effect on integral construction efficiency, provides a kind of pile foundation concrete cast small reducer union that becomes larger of conduit.
The purpose of this utility model is achieved through the following technical solutions：
A kind of pile foundation concrete pours into a mould the small reducer union that becomes larger of conduit, including integrally formed coupling tube；The transition
Pipe both ends diameter is different, and medium position uses canalis spinalis transition；Described smaller one end of transition pipe diameter is provided with externally threaded public affairs
Connector；One end that the coupling tube is relatively large in diameter sets female female connector；Connector spiral shell is provided on the outside of the female connector
Cap；Anti-avulsion stirrup is additionally provided on one end that the coupling tube is relatively large in diameter.
Further, in order to improve the service life of coupling tube, the coupling tube is made of stainless steel, and is carried out resistance to
Mill and anti-corrosion treatment.
Further, burr etc. scratches user of service during use in order to prevent, and the coupling tube carries out deburring overlap
Processing.
Compared with prior art, the utility model has at least the following advantages：
The pile foundation concrete cast small reducer union that becomes larger of conduit of the utility model, by the way that both ends diameter is set to differ
It causes, the intermediate coupling tube by canalis spinalis transition is provided with externally threaded pin end, one be relatively large in diameter in the smaller one end of diameter
End sets female female connector, and collar nut is set outside female connector, realizes nothing and needs to change conduit to realize concrete material
Bucket exports the caliber purpose consistent with blanking conduit caliber, is greatly saved the time required to replacing conduit, time saving and energy saving, significantly
Improve construction efficiency.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to the structure shown in these attached drawings.
Fig. 1 is that the pile foundation concrete of the utility model pours into a mould the structure diagram of the small reducer union that becomes larger of conduit.
Reference sign：1- coupling tubes；101- canalis spinalis；2- pin ends；3- female connectors；4- collar nuts；5- anti-avulsion hoops
Muscle.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment.
Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained shall fall within the protection scope of the present invention.
In the utility model unless specifically defined or limited otherwise, term " connection ", " fixation " etc. should do broad sense reason
Solution, for example, " fixation " can be fixedly connected or be detachably connected or integrally；It can be mechanical connection, also may be used
Be electrical connection；It can be directly connected, can also be indirectly connected by intermediary, can be the connection inside two elements
Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with
Concrete meaning of the above-mentioned term in the utility model is understood as the case may be.
In addition, the technical solution between each embodiment of the utility model can be combined with each other, but must be with ability
Domain those of ordinary skill can be implemented as basis, will be understood that when the combination appearance of technical solution is conflicting or can not realize
The combination of this technical solution is not present, also not within the protection domain of the requires of the utility model.
As shown in Figure 1, a kind of pile foundation concrete cast small reducer union that becomes larger of conduit, including integrally formed coupling tube
1；The 1 both ends diameter of coupling tube is different, and medium position uses 101 transition of canalis spinalis；Described smaller one end of 1 diameter of coupling tube is set
It is equipped with externally threaded pin end 2；One end that the coupling tube 1 is relatively large in diameter sets female female connector 3；The female connector
3 outsides are provided with collar nut 4；Anti-avulsion stirrup 5 is additionally provided on one end that the coupling tube 1 is relatively large in diameter.
Preferably, in order to improve the service life of coupling tube, the coupling tube 1 is made, and carry out using stainless steel
Wear-resisting and anti-corrosion treatment.
Preferably, burr etc. scratches user of service during use in order to prevent, and the coupling tube 1 carries out deburring overlap
Processing.
The course of work of the pile foundation concrete cast small reducer union that becomes larger of conduit of the utility model is as follows：
In use, when the outlet caliber of concrete hopper is less than blanking conduit caliber, the smaller one end of 1 diameter of coupling tube is connected
The outlet of concrete hopper is connect, is relatively large in diameter one end connection blanking conduit.
More than, the only preferable specific embodiment of the utility model, but the protection domain of utility model is not limited to
This, in the technical scope that any one skilled in the art discloses in the utility model, the variation that can readily occur in
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with right
