Description
Technical Field
The utility model belongs to the technical field of directional horizontal drilling hard rock reaming restoration in ground.
Background
At present, the coal industry adopts a ground directional horizontal drilling technology to implement advanced treatment engineering of a water damage area, the effect is good, the drilling is carried out in the ground towards the inner part of a stratum, when a drill bit reaches the horizontal position of a water outlet point, the drill bit is controlled to change the direction towards the horizontal direction and continue to drill until the directional horizontal drilling engineering in the water outlet area is completed, then the drill bit is withdrawn, water plugging materials are injected into the water outlet area by utilizing the drilling, the water outlet point and a water inflow channel are plugged, and the safe production of a mine is not influenced by water outflow. But because the stratum is harder in the work progress, the aperture of drill bit cutting is mostly irregular, and downthehole local formation keyway causes the sticking of a drill easily, sets up the sleeve pipe unsmooth, and the drilling orbit is longer simultaneously, rubs and hinders too big, the drilling tool backing pressure is serious for 30% downforce of drilling machine acts on the wall of a well and can't transmit to the drill bit, seriously influences service efficiency such as drill bit, screw rod, drilling tool, causes drilling tool life weak point, the well drilling in-process accident often takes place.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hole wall is of high quality, the sleeve pipe has been set smoothly, the higher directional horizontal drilling hard rock reaming prosthetic devices in ground of drilling efficiency, can implement to creep into, can ream again and restore drilling.
In order to realize the above purpose, the utility model discloses a: the drilling rod, go up reaming restorer, the sleeve pipe, under reaming restorer, the drill bit, the upper end of going up reaming restorer adopts the screw thread to be connected with the drilling rod, the lower extreme of going up reaming restorer adopts the screw thread to be connected with the sleeve pipe upper end, the upper end of under reaming restorer adopts the screw thread to be connected with the sleeve pipe lower extreme, the lower extreme of under reaming restorer adopts the screw thread to be connected with the drill bit, go up, under reaming restorer comprises sleeve and centering strip, three centering strips evenly fix in the sleeve outside, inlay the wear-resisting alloy piece on every centering strip.
The utility model has the advantages that: when the construction drilling is carried out, the hole expanding and repairing can be carried out on the drilled hole, the hole diameter of the drilled hole is expanded and repaired, the working state of the drilling machine is stable, the well wall quality is good, the hole forming rate is improved, the hole diameter expansion rate can reach 20%, and the drilling machine is smoothly arranged under the sleeve. Regular drilling holes are cut by the repairing drill bit, the aperture of the flow passage is increased, the sand carrying capacity is improved, drilling accidents caused by drill sticking are reduced, and the drilling construction is safer.

Detailed Description
As can be seen from fig. 1 and 2, the present invention includes: the drill pipe 1, the upper reaming restorer 2, the casing 3, the lower reaming restorer 4 and the drill bit 5. The upper end of the upper reaming restorer 2 is connected with the drill rod 1 through a screw thread, and an external screw thread is arranged on a drill rod male thread and is matched with an internal screw thread structure of the upper reaming restorer. The lower end of the upper reaming restorer 2 is connected with the upper end of the sleeve 3 through a screw thread, the upper end of the lower reaming restorer 4 is connected with the lower end of the sleeve 3 through a screw thread, and the upper reaming restorer and the lower reaming restorer are slightly larger than the outer diameter of the sleeve, so that the sleeve can conveniently and smoothly restore the formed hole diameter through reaming. The lower extreme of underreaming restorer 4 adopts the screw thread to be connected with drill bit 5, and drilling rod, last underreaming restorer, sleeve pipe, underreaming restorer all adopt high-quality wear-resisting steel casting processing to form with the drill bit, set up to cylindric structure, and inside is cavity for utilize the inside of drilling rod to pour into mud and water into to the drill bit when drilling, be used for to the drill bit cooling and carry out the detritus outward. The upper reaming restorer and the lower reaming restorer are composed of a sleeve 6 and cutting righting strips 7, and the three cutting righting strips are uniformly fixed on the outer side of the sleeve. Each cutting centralizing strip is inlaid with a wear-resistant alloy sheet 8 for keeping the outer diameter size of the reaming restorer and avoiding long-term abrasion and reducing the aperture. When the device is used, the device can be installed on a drilling machine through a drill rod, and when a drill bit drills, the upper reaming restorer and the lower reaming restorer perform reaming restoration operation on drilled holes, so that drilled holes with good quality are constructed, and directional and horizontal drilling engineering in a water outlet area is smoothly completed through a control system. The utility model discloses a specification size can be according to different specifications such as sleeve pipe external diameter, drill bit size, drilling rod make different reaming repair series varieties.
