Abstract

The utility model discloses a rock drilling drill stem which comprises an outer sleeve rod, an inner sleeve rod, a sleeve rod baffle ring and a signal wire. The outer sleeve rod comprises a male connector at the upper end of the outer sleeve rod and a female connector at the lower end of the outer sleeve rod. The inner sleeve rod is installed in the outer sleeve rod, the sleeve rod baffle ring is installed in the portion, below the inner sleeve rod, of the outer sleeve rod, the sleeve rod baffle ring is used for limiting the position of the inner sleeve rod, a closed annular cavity is formed among the outer sleeve rod, the inner sleeve rod and the sleeve rod baffle ring, the top of the male connector and the bottom of the sleeve rod baffle ring are respectively provided with a conducting ring, an upper wiring hole is formed in the male connector, a lower wiring hole is formed in the sleeve rod baffle ring, a signal wire is installed in the annular cavity, and two ends of the signal wire are connected with the conducting rings through the upper wiring hole and the lower wiring hole respectively. The rocking drilling drill stem has the advantages of being simple in structure and capable of meeting requirements of power transmission of rock drilling and achieving transmission of signals step by step among a plurality of drill stems in the rocking drilling process.

Description

The rock drilling drilling rod
Technical field
The utility model relates to a kind of rock drilling drilling rod, relates in particular to a kind of rock drilling drilling rod of realizing that signal transmits step by step.
Background technology
In mining technology; all need the Drilling shot hole; the degree of depth in the hole of mining borehole blasting at present requires not wait to tens meters at several meters; increase along with drilling depth; phenomenons such as inclined to one side drill chuck brill take place in drilling rod through regular meeting; operating mode for can be to the drilling rod rock drilling time is monitored in real time; normally at rig swiveling head location arrangements sensor; the parameter that influences drilling rod deflection and bit freezing is gathered; because the deflection of drilling rod and bit freezing all occur in the drill bit position at the bottom of the hole; rig swiveling head station acquisition to the rock drilling data often can not reflect deflection and the bit freezing mechanism of drilling rod truly; and along with drilling depth increases; data have obvious hysteresis, can not in time carry out the anti-sticking correction to rig and handle.
The utility model content
The purpose of this utility model is to provide a kind of rock drilling drilling rod that signal at the bottom of the hole can be delivered to the face of land with wired transmission manner step by step.
The rock drilling drilling rod that the utility model provides, comprise outer loop bar, interior loop bar, loop bar baffle ring and holding wire, described outer loop bar comprises the male joint of upper end and the female joint of lower end, loop bar is installed in the outer loop bar in described, the position of loop bar in being used for limiting in the outer loop bar of loop bar below in described loop bar baffle ring is installed in, described outer loop bar, form the annulus chamber of a sealing between interior loop bar and the loop bar baffle ring, be separately installed with a conducting ring at the top of this male joint and the bottom of loop bar baffle ring, have wiring hole in this male joint, have wiring hole at described loop bar baffle ring, described holding wire is installed in the annulus chamber, and these holding wire two ends link to each other with conducting ring with following wiring hole by last wiring hole respectively.
The upper end of loop bar is by being fastened in the outer loop bar with the male joint inside thread in described.
Described loop bar baffle ring is installed on described female joint inboard by being threaded.
The utility model is in drilling rod inside, and holding wire places in the annulus chamber, and its two ends are connected the conducting ring on outer loop bar male joint and the loop bar baffle ring through upper and lower wiring hole, realizes the drilling rod internal signal transmission; In the drilling rod outside, male joint by the outer loop bar of a drilling rod agrees with being connected of back realization adjacent drill pipes with the female joint of the outer loop bar of another drilling rod, at this moment, conducting ring on the top drilling rod loop bar baffle ring contacts with the conducting ring end face on the following fillet of tool joint pins, signal transmission interface is connected immediately, realizes the transmission of drilling rod external signal.The utility model is simple in structure, can satisfy rock drilling power transmission, the transmission step by step of signal between many drilling rods in the time of realizing rock drilling boring again.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model signal transmission schematic diagram.
The specific embodiment
As can be seen from Figure 1, this rock drilling drilling rod of the utility model, comprise outer loop bar 1, interior loop bar 2, loop bar baffle ring 3, holding wire 4 and some conducting rings 6, wherein outer loop bar 1 comprises the male joint 11 of upper end and the female joint 12 of lower end, interior loop bar 2 is installed in the outer loop bar 1, its upper end is by screw thread and 11 inboard connections of male joint, in loop bar baffle ring 3 is installed in by being threaded in the female joint 12 of outer loop bar 1 of loop bar 2 belows, the position of loop bar 2 in being used for limiting, outer loop bar 1, form the annulus chamber 5 of a sealing between interior loop bar 2 and the loop bar baffle ring 3, conducting ring 6 is installed in the top of male joint 11 and the bottom of loop bar baffle ring 3 respectively, have wiring hole 13 in male joint 11, have wiring hole 31 at loop bar baffle ring 3, holding wire 4 is installed in the annulus chamber 5, and these holding wire 4 two ends link to each other with conducting ring 6 with following wiring hole 31 by last wiring hole 13 respectively.
As shown in Figure 2, the utility model in use, sensor is installed in the front portion of first drilling rod, the holding wire of this sensor is connected with conducting ring 6 in this male joint 11, adjacent drill pipes then the female joint 12 by separately and male joint 11 screw threads screw tighten after, make the conducting ring 6 on the drilling rod loop bar baffle ring 3 contact with conducting ring 6 end faces on another fillet of tool joint pins 11, realize the hole at the bottom of signal be delivered to the face of land with wired transmission manner step by step.
