Unless explicitly required, separate components and functions are optional, and the order of operation may vary. The parts and features of some embodiments may be included in or replace the parts and features of other embodiments. The scope of the embodiments of the present invention includes the entire scope of the claims, and all available equivalents of the claims.

[0026] like Figures 2 to 8 As shown, in some illustrative embodiments, a deep hole pressure relief drilling rig for internal slag removal is provided, the power part and drilling tools of the deep hole pressure relief drilling rig for internal slag removal are arranged on a frame, and the frame includes: a support plate 7, a bracket 8, a bracket guide rail 9, a support plate telescopic cylinder 15, a bracket telescopic cylinder 14, a flip beam 10, a rocker 11, a slewing support seat 12, a flip cylinder 17, a rocker lifting cylinder 16, a slewing bearing 13 and a crawler traveling vehicle 18, and a hydraulic power source 19.

[0027] The reducer 2 is arranged on the pallet 7, and the pallet 7 is arranged on the bracket 8. The pallet 7 and the bracket 8 are limited by a guide mechanism. The guide mechanism can be a guide rail, including a track and a slider. The slider can move on the track. The bracket 8 is connected to the track, and the pallet 7 is connected to the slider, so that the pallet 7 can move along the bracket 8 under the action of the guide mechanism. The action end of the pallet telescopic cylinder 15 is hinged on the pallet 7, and the fixed end of the pallet telescopic cylinder 15 is hinged on the bracket 8. When the pallet telescopic cylinder 15 works, it can drive the pallet 7 to move on the bracket 8, thereby driving the reducer 2 to move.

[0028] The bracket 8 is arranged on the bracket guide rail 9, the action end of the bracket telescopic cylinder 14 is hinged on the bracket 8, and the fixed end of the bracket telescopic cylinder 14 is hinged on the bracket guide rail 9. The bracket 8 and the bracket guide rail 9 are limited by a guide mechanism, and the guide mechanism can be a guide rail, including: a track and a slider, the slider can move on the track, the bracket guide rail 9 is used as a track, and the bracket 8 is connected to the slider, so that the bracket 8 can move along the bracket guide rail 9 under the action of the guide mechanism. When the bracket telescopic cylinder 14 works, it can drive the bracket 8 to move on the bracket guide rail 9, thereby driving the pallet 7 and the reducer 2 to move.

[0029] The bracket guide rail 9 is arranged on the flip beam 10, and one end of the rocker 11 is hinged to the flip beam 10, and the other end is hinged to the slewing support seat 12. One end of the flip cylinder 17 is hinged to the flip beam 10, and the other end is hinged to the slewing support seat 12. When the flip cylinder 17 is actuated, the flip beam 10 can be pushed to flip around the hinge point between the rocker 11 and the flip beam 10, so that the support plate 7 and the bracket 8 are flipped, thereby driving the power part and the drilling tool to rotate to adjust the tilt angle. One end of the rocker lifting cylinder 16 is hinged to the rocker 11, and the other end is hinged to the slewing support seat 12. When the rocker lifting cylinder 16 is actuated, it can drive the end of the rocker 11 hinged to the flip beam 10 to rise / fall, thereby adjusting the height of the flip beam 10, thereby adjusting the height of the flip beam 10, and finally adjusting the height of the power part and the drilling tool of the drilling rig.

[0030] The slewing support seat 12 is arranged on the crawler traveling vehicle 18 through the slewing bearing 13, so that the slewing support seat 12 can rotate on the crawler traveling vehicle 18, thereby adjusting the angle of the power part of the drilling rig and the drilling tool. A hydraulic power source 19 is also arranged on the crawler traveling vehicle 18, and the hydraulic power source 19 provides power for all devices on the drilling rig that require hydraulic pressure to operate.

[0031] In the above, the action end of the pallet telescopic cylinder 15 and the bracket telescopic cylinder 14 refers to the end of the telescopic cylinder that can move, such as the piston rod, and the fixed end of the pallet telescopic cylinder 15 and the bracket telescopic cylinder 14 refers to the end of the telescopic cylinder that does not move, such as the piston cylinder.

[0032] The hinge point between the rocker 11 and the slewing support seat 12 and the hinge point between the flip cylinder 17 and the slewing support seat 12 are located on the same axis, so that when the flip cylinder 17 is in action, the flip beam 10 can be flipped stably and quickly, making flipping easier and reducing power consumption.

[0033] like Figure 1 As shown, during the construction process of the traditional drilling rig, the debris is removed along the gap between the outer wall of the borehole 101 and the drill rod 102. In the actual construction process, the following problems exist: since the debris is removed along the gap between the outer wall of the borehole and the drill rod, the borehole is enlarged, and horizontal hole construction is prone to cause partial hole emptying and drill jamming; high local pressure and high-pressure gas state are prone to blowhole accidents, resulting in the inability to construct; when deep holes are constructed, the debris cannot be discharged, causing drill jamming; due to the difficulty in slag removal, the overhead hole cannot be constructed.

[0034] The power part of the internal slag removal deep hole pressure relief drilling rig of the present invention includes: a hydraulic motor 1, a reducer 2, a clamp 5, and a clamp 6. The power input shaft of the reducer 2 is connected to the hydraulic motor 1, and the clamp 5 is arranged at the front end of the power output shaft 21 of the reducer 2 and connected to the power output shaft 21 of the reducer. A gear transmission mechanism is arranged in the reducer 2, and the gear transmission mechanism transmits power from the power input shaft to the power output shaft 21 through meshing gears. The function of the clamp 5 is to clamp the dual-channel drill rod 28, and the clamp 5 clamps the dual-channel drill rod 28 on the front end of the power output shaft 21 to ensure that the dual-channel drill rod 28 rotates synchronously with the power output shaft 21. The clamp 6 acts as a bearing, mainly supporting the middle part of the dual-channel drill rod 28. When working, the hydraulic motor 1 drives the reducer 2 to work, thereby driving the clamp 5 to rotate, and further drives the dual-channel drill rod 28 to move, thereby completing the drilling operation.

[0035] The drilling tool of the internal slag discharge deep hole pressure relief drilling rig of the present invention comprises: a slag gas separator 3, a protective cover 4, a rotating nut 26, a connector 27, a dual-channel drill pipe 28, a drill bit 31 and a water jet 32. The slag gas separator 3 is arranged on the rear end cover 20 of the power output shaft of the reducer, and forms a slag collection chamber 22 with the rear end cover 20 of the power output shaft. The power output shaft 21 of the reducer is a hollow output shaft, and the internal space of the power output shaft of the reducer, that is, the hollow part of the power output shaft is connected with the slag collection chamber 22. The connector 27 is arranged in the slag collection chamber 22, the rotating nut 26 is arranged on the slag gas separator and covered by the protective cover 4, and the connector 27 is connected to the rotating nut 26. The dual-channel drill pipe 28 is clamped by the clamp 5, one end of the dual-channel drill pipe 28 is connected to the drill bit 31, and the other end passes through the hollow part of the power output shaft 21 of the reducer and then extends into the slag collection chamber 22 and is connected with the connector 27. The water jet 32 ​​is disposed on the drill bit 31 .

[0036] like Figure 7 As shown, the dual-channel drill pipe 28 includes: an outer sleeve 34 and an inner sleeve 35 arranged inside the outer sleeve 34 , a water injection channel 30 is formed inside the inner sleeve 35 , a slag discharge channel 29 is formed between the outer surface of the inner sleeve 35 and the inner surface of the outer sleeve 34 , and the slag discharge channel 29 is connected to the slag collection chamber 22 .

[0037] The rotating nut 26 and the connector 27 are hollow shafts, and the hollow parts are connected to the water injection channel 30 of the dual-channel drill pipe 28.

[0038] During operation, the frame adjusts the position and angle of the power part and the drilling tool first, and the hydraulic motor 1 passes through the reducer 2, and the power output shaft 21 of the reducer 2 rotates, and the power output shaft 21 of the reducer 2 drives the clamp 5 to rotate, and the clamp 5 drives the dual-channel drill pipe 28, the drill bit 31, and the water jet 32 ​​to rotate and cut the rock mass 33. Water and other media enter the water injection channel 30 of the dual-channel drill pipe 28 from the rotating nut 26 and the connector 27 in turn, and carry the slag from the slag discharge channel 29 to return to the slag collection chamber 22. The slag gas separator 3 is provided with a slag discharge hole 24, an exhaust hole 25 and a medium input hole 23, and the gas is discharged from the exhaust hole 25 on the slag gas separator 3, and the slag water is discharged from the slag discharge hole 24 on the slag gas separator 3, so as to achieve gas-liquid separation. During the entire drilling process, the dual-channel drill pipe 28 extends under the action of the frame, and the water jet 32 ​​cuts and relieves pressure. A slag-gas separator 3 is installed on the reducer 2. The structure of the slag-gas separator 3 combined with the hollow power output shaft of the reducer and its matching dual-channel drill rod 28 can realize slag discharge in the drilling rig to avoid blowhole accidents; it can quickly cool the reducer oil temperature and increase the service life of the reducer; the slag-gas separator 3 can be connected to a mud pump to facilitate deep hole slag discharge construction, which is convenient for slag discharge and environmentally friendly.
