Abstract
The utility model discloses a novel double-barrelled unit head that creeps into for colliery includes reducing gear box, gyration holder, supplementary row's sediment device and initiative drilling rod, characterized by: the reduction gearbox is connected with one end of the rotary clamp holder, the other end of the rotary clamp holder is connected with one end of the auxiliary slag discharging device, and the other end of the auxiliary slag discharging device is connected with the driving drill rod. The beneficial effects are that: the drilling mode of clamping the drill rod and the mode of connecting the drill rod through the driving drill rod to drill are combined, the two modes are integrated on one power head, one power head can drive drilling tools with two specifications, and double-pipe drilling is achieved. In the working process, slips of different specifications do not need to be replaced, and pore-forming construction of a larger aperture can be completed through one-time construction.
Description
Technical Field
The utility model relates to a double-barrelled unit head that creeps into, especially a novel double-barrelled unit head that creeps into for colliery.
Background
The existing large-aperture drilling construction mostly adopts the mode that drilling holes with small apertures are drilled firstly, and then a reaming bit is replaced to connect a drill rod for reaming drilling. In the whole drilling process, if a small-specification drill rod is adopted to connect different drill bits, the requirement on the drill rod is high, and the damage to the drill rod is large; if different drill rods and different drill bits are adopted in the mining process, the slips of the power head and the matched equipment need to be replaced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the weak point of above-mentioned problem, provide a novel double-barrelled unit head that creeps into for colliery.
In order to overcome the technical problem, the utility model discloses a technical scheme is:
the device comprises a reduction gearbox, a rotary clamper, an auxiliary slag discharge device and a driving drill rod, and is characterized in that: the reduction gearbox is connected with one end of the rotary clamp holder, the other end of the rotary clamp holder is connected with one end of the auxiliary slag discharging device, and the other end of the auxiliary slag discharging device is connected with the driving drill rod.
Slips are arranged in the rotary clamp holder and connected with the inner pipe, and the driving drill rod is in threaded connection with the sleeve.
Compared with the prior art, the beneficial effects of the utility model are that: the drilling mode of clamping the drill rod and the mode of connecting the drill rod through the driving drill rod to drill are combined, the two modes are integrated on one power head, one power head can drive drilling tools with two specifications, and double-pipe drilling is achieved. In the working process, slips of different specifications do not need to be replaced, and pore-forming construction of a larger aperture can be completed through one-time construction.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a front view of the present invention.
FIG. 2 is a schematic view of a bushing-coupling device assembly.
FIG. 3 is a schematic view of the inner tube clamping and sleeve connection.
Fig. 4 is a partial enlarged view of the area II shown in fig. 3.
Detailed Description
As can be seen from figures 1-4, the device comprises a reduction gearbox 1, a rotary clamper 2, an auxiliary slag discharge device 3 and a driving drill rod 4, wherein the reduction gearbox 1 is connected with one end of the rotary clamper 2, the other end of the rotary clamper 2 is connected with one end of the auxiliary slag discharge device 3, and the other end of the auxiliary slag discharge device 3 is connected with the driving drill rod 4. Slips 6 are arranged in the rotary clamp holder 2, the slips 6 are connected with an inner pipe 5, and the driving drill rod 4 is in threaded connection with a sleeve 7. The inner pipe 5 is clamped by the rotary clamp 4, and the driving drill rod 4 is in threaded connection with the casing 7.
During the working process, when the slips 6 clamp the inner pipe 5, the driving drill rod 4 is not connected with the sleeve 7 at the moment, and a certain working distance exists, and the inner pipe 5 drills forwards; when the slips 6 do not clamp the inner pipe 5, the active drill rod 4 is connected with the casing 7, and the active drill rod 4 drives the casing 7 to drill forwards. Finally, the primary pore-forming drilling with larger pore diameter is realized.
The left end of reducing gear box 1 is connected driving motor, under the driving motor effect, for equipment creeps into and provides the moment of torsion, the output main shaft of reducing gear box 1 is connected with gyration holder 2 and is driven gyration holder 2 rotatory, the double-barrelled inner tube 5 that creeps into the in-process of 2 centre grippings of gyration holder can make inner tube 5 rotatory, initiative drilling rod 4 is connected with gyration holder 2, initiative drilling rod 4 is connected with double-barrelled sleeve pipe 7 that creeps into the in-process through front end screw thread, conduction through gyration holder 2, can be on the sleeve pipe 7 with rotatory moment of torsion conduction, supplementary row's sediment device 3 suits is on initiative drilling rod 4, the effect is to the sediment etc. are collected to the returning water of creeping.
The drilling mode of clamping the drill rod and the mode of connecting the drill rod through the driving drill rod to drill are combined, two modes are integrated on one power head, one power head can drive drilling tools with two specifications, double-pipe drilling is achieved, simultaneous or alternate drilling of the two drilling tools is achieved in the drilling process, slips of the power head and matched equipment do not need to be replaced, one-time pore-forming drilling with larger aperture is achieved, and drilling efficiency is improved.
The present invention is not limited to the precise arrangements described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
