Abstract
The utility model discloses a kind of tripartite's guide rod, comprise triangle urceolus, inner core, socket and spigot, described inner core is fixedly installed in described triangle urceolus, two ends are inserted interior socket and are fixed with it, described inside and outside joint is separately positioned on triangle urceolus two ends, the dead in line of described inner core and described triangle urceolus.The triangle urceolus of this tripartite's guide rod and inner core be coaxially arranged so that drilling rod can obtain larger inertia force rotating in drilling process, centrifugal force is less, and drilling process is more laborsaving.
Description
Technical field
The utility model relates to mining equiment, particularly relates to a kind of triangular drill rod.
Background technology
In the prior art, the drilling rod that mining equiment uses mostly is round drill rod and auger stem, round drill rod and auger stem intensity difference, resistance is unfavorable for deslagging greatly, and drilling depth is limited, can not draw out methane in boring procedure simultaneously, the inner core of tripartite's guide rod and urceolus are coaxial setting, and creeping in rotary course, resistance is little, be beneficial to deslagging, the moment of torsion born between multistage drilling rod is large.Compare original drilling rod advantage: resistance is little, is beneficial to deslagging, and under equal conditions, drilling depth is long, gas drainage pipe can be inserted by inner core in drilling rod situation and draw out methane not getting, greatly reduce labour intensity, improve operating efficiency, reduce cost of production.
Utility model content
For above-mentioned shortcoming and defect of the prior art, the purpose of this utility model is to provide a kind of light and flexible, creeps into easy tripartite's guide rod.
The purpose of this utility model is achieved through the following technical solutions:
A kind of triangular drill rod, comprise triangle urceolus, inner core, socket and spigot, described inner core is fixedly installed on two ends in described triangle urceolus and is connected with interior socket, described inside and outside joint is arranged on the two ends of described inner core and urceolus, and described inner core, triangle urceolus, spigot and socket are on the same axis.
Preferably, the end of described triangle urceolus is given prominence in described socket, and described socket has external screw thread.
Preferably, described spigot is the female interface of tool by being formed away from the inwall tapping of socket one end at described triangle urceolus.
Preferably, described socket is conical head, and described spigot has the inner chamber corresponding to described socket shape.
Compared with prior art, the utility model embodiment at least has the following advantages:
In the utility model embodiment, the triangle urceolus of tripartite's guide rod and inner core be coaxially arranged so that drilling rod can obtain larger inertia force rotating in drilling process, drilling process is more laborsaving.
Accompanying drawing explanation
fig. 1 is the structural representation of the utility model tripartite guide rod.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing 1 thereof, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of triangular drill rod, comprise triangle cylinder 2, inner core 3, socket 1 and spigot 4, described inner core 3 is arranged on two ends in described triangle urceolus 2 and is connected with interior socket, described socket 1, spigot 4 are arranged on the two ends of described triangle cylinder 2 and inner core 3, inside and outside fitting end gable inserts the endoporus of triangle cylinder 2, coordinate for tight fit, seam portion need carry out soldering, and the axis spacing of described inner core 3 and described triangle urceolus 2 is zero.
The end of described triangle urceolus 2 is given prominence in described socket 1, and described socket 1 has external screw thread.
Described spigot 4 is the female interface of tool by being formed away from the inwall tapping of socket 1 one end at described triangle urceolus 2.
Described socket 1 is conical head, and described spigot 4 has the inner chamber corresponding to described socket 1 shape.During use, usual multistage tripartite's guide rod head and the tail are threaded connection application.
The triangle urceolus 2 of tripartite's guide rod and inner core 3 be coaxially arranged so that drilling rod can obtain larger inertia force rotating in drilling process, drilling process is more laborsaving
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
Claims (4)
