[0061] A right-angle steering gear 2 is rotatably connected to the top of the rotating support 11. The input shaft of the steering gear 2 is connected and fixed to the output shaft of the top gearbox 13 of the movable seat 1 through a universal joint coupling 21. The output shaft of the steering gear 2 is fixedly connected to a transmission sleeve 22 vertically upward. Referring to the drawings, the input shaft and the output shaft of the steering gear 2 are connected through conical gear transmission. The transmission sleeve 22 is located in the housing of the steering gear 2 and is rotatably connected thereto;

[0062] The mast frame 3 is fixedly connected with the steering gear 2, and a transmission shaft 31 is arranged on the mast frame 3. The bottom of the transmission shaft 31 is connected to the transmission sleeve 22, and the top of the transmission shaft 31 is rotatably connected to the mast frame 3. More specifically, the cross section of the transmission shaft 31 is a regular polygon, and in this embodiment, the cross section of the transmission shaft 31 is a regular hexagon. The transmission sleeve 22 corresponds to the transmission shaft 31 so that the transmission sleeve 22 can drive the transmission shaft 31 to rotate synchronously.

[0063] The lifting driving member 4 is arranged on the front side of the mast frame 3. The lifting driving member 4 comprises a first lifting oil cylinder 41 arranged symmetrically on the front side of the mast frame 3, a vertical guide rail 42 fixed to the mast frame 3 and located on the rear side of the first lifting oil cylinder 41, and a sliding seat 43 arranged on the guide rail 42 and in sliding guide cooperation with the guide rail 42.

In this embodiment, the slewing gear 5 and the sliding seat 43 are fixedly connected to the cylinder body of the first lifting oil cylinder 41. More specifically, a sliding sleeve 51 sleeved on the transmission shaft 31 and slidable up and down along the transmission shaft 31 is arranged in the housing of the slewing gear 5. A connecting sleeve 52 for connecting a drill rod is also arranged in the housing of the slewing gear 5. The sliding sleeve 51 and the connecting sleeve 52 are both rotatably connected to the housing of the slewing gear 5 and are in gear meshing transmission. Referring to the drawings, a transmission gear 53 is rotatably connected to the position between the sliding sleeve 51 and the connecting sleeve 52 in the housing of the slewing gear 5, and the outer walls of the sliding sleeve 51 and the connecting sleeve 52 are both fixed with gear teeth in meshing cooperation with the transmission gear 53. In this way, when the transmission shaft 31 drives the sliding sleeve 51 to rotate, the sliding sleeve 51 drives the transmission gear 53 to rotate through the gear teeth on the outer wall thereof, and the transmission gear 53 drives the connecting sleeve 52 to rotate through the gear teeth on the outer wall of the connecting sleeve 52. Through this series of transmission, the transmission shaft 31 drives the connecting sleeve 52 of the slewing gear 5 to rotate, and further drives the drill rod to rotate, thereby achieving the drilling effect.

[0065] The angle adjusting member 6 is arranged on the rear side of the mast frame 3 and adjusts the inclination angle of the mast frame 3. In this embodiment, the angle adjusting member 6 is a second lifting oil cylinder. The bottom of the second lifting oil cylinder is hingedly connected to the machine seat 1 which can slide forward and backward and is located on the rear side of the mast frame 3, and the top of the second lifting oil cylinder is hingedly connected to the middle part of the mast frame 3.

[0066] In order to improve the stability of the mast frame 3 after tilting, an auxiliary diagonal brace 7 is arranged at the position where the forward and backward sliding base 1 is located at the rear side of the mast frame 3. The auxiliary diagonal brace 7 comprises a diagonal brace outer tube 71 hingedly connected to the bottom of the forward and backward sliding base 1, a diagonal brace inner tube 72 hingedly connected to the top of the mast frame 3 and extending into the diagonal brace outer tube 71, and a locking clamp 73 for fixing the relative position of the diagonal brace outer tube 71 and the diagonal brace inner tube 72. It should be noted that the locking clamp 73 can have the following structure: the locking clamp 73 has two half-circular clamps, and the two half-circular clamps are locked by bolts to clamp the connection between the diagonal brace outer tube 71 and the diagonal brace inner tube 72, thereby fixing the relative position of the diagonal brace outer tube 71 and the diagonal brace inner tube 72.

[0067] In the present embodiment, the top of the mast frame 3 is provided with a crown block 8, and the top of the crown block 8 is symmetrically fixed with an upper section mast 81. The bottom of the upper section mast 81 is fixed through a guide pipe 32 at the top of the front side of the mast frame 3 and is connected to the extension end of a third lifting oil cylinder 33. The bottom of the third lifting oil cylinder 33 is vertically connected to the mast frame 3. The upper section mast 81 is uniformly and spacedly provided with through pin holes 811 at the position close to the bottom of the third lifting oil cylinder 33.

[0068] The forward and backward sliding base 1 is fixed with a multi-gear gearbox and a winch 14. A steel wire rope 15 on the winch 14 is sequentially connected to a lifting device 83 through a rope collector 10 fixed at the winch 14, guide pulleys 82 at the bottom of the rear side of the mast frame 3 and the rear and front ends of the crown block 8, and is hung on the front side of the crown block 8. The rope collector 10 comprises a diagonal brace frame 101 fixed on the forward and backward sliding base 1, a fixed sleeve 102 fixed on the top of the diagonal brace frame 101, a stand column 103 sleeved in the fixed sleeve 102 and rotationally connected with the fixed sleeve 102, a fixed sliding sleeve 104 (the inside of the fixed sliding sleeve 104 is a bearing, and the stand column 103 is fixedly connected to the inner ring of the bearing in an interference fit) rotationally connected to the bottom of the stand column 103 and fixedly connected to the forward and backward sliding base 1, a mounting plate 105 fixed on the top of the stand column 103, two pulley sets 106 spacedly mounted on the mounting plate 105, and an auxiliary sliding sleeve 107 sleeved on the middle part of the stand column 103 and rotationally connected with the stand column 103 and fixed on the forward and backward sliding base 1. In addition, the structure of the guide pulley 82 at the position of the rotary support 11 is shown in FIG. 8. Two metal plates are provided at the top, each of which is provided with a pulley. The two metal plates are vertically fixed with each other on one side, and two pulleys are further spacedly mounted on the two metal plates. Figure 12

[0069] ​In addition, in the embodiment, the adjustable foot support frame 9 is fixed to the bottom of the rear side of the mast frame 3, the adjustable foot support frame 9 comprises a top support outer frame 91 fixed to the bottom of the mast frame 3, a top support inner frame 92 slidingly guided with the top support outer frame 91, a top pin plate 93 hinged to the bottom of the top support inner frame 92, and a fourth lifting oil cylinder 94 hinged to the top of the top support outer frame 91 at the upper end and hinged to the bottom of the top support inner frame 92 at the lower end. The top support outer frame 91 is symmetrically provided with two rectangular sleeve pipes 911, and the top support inner frame 92 is symmetrically provided with inner pipe bodies 921 inserted into the sleeve pipes 911. The adjustable foot support frame is long.

[0070] Alternatively, the adjustable foot support frame 9 comprises two limiting pipes 95 fixed to the bottom of the mast frame 3, a stiffening plate 96 fixedly connected between the two limiting pipes 95, and an adjusting screw rod 97 threadedly connected to the stiffening plate 96. The bottom of the adjusting screw rod 97 is rotatably connected to a channel steel plate 98 after penetrating the stiffening plate 96, the channel steel plate 98 is fixedly provided with two limiting rods 99 inserted into the limiting pipes 95 at the top, and the bottom of the two limiting rods 99 is hinged to a top pin plate 93. The adjustable foot support frame is short.

[0071] Finally, in the embodiment, the mast frame 3 is fixed with an orifice centralizer 39 below the rotary head 5. The orifice centralizer 39 comprises a fixed plate 391 fixedly connected to the mast frame 3 and an orifice plate 392 fixedly connected to the fixed plate 391 and perpendicular to the mast frame 3, and a limiting sliding sleeve 393 with an adjustable center and a bearing is installed in the middle of the orifice plate 392. In use, the drill rod is connected to the connecting sleeve 52 on the rotary head 5 at the top and penetrates the limiting sliding sleeve 393 at the bottom, so that the drill rod can be offset when drilling.

[0072] It should be noted that the movable seat 1 is also provided with a hydraulic oil pump 16 connected to the first lifting oil cylinder 41, the second lifting oil cylinder, the third lifting oil cylinder 33 and the fourth lifting oil cylinder 38. When the power assembly 12 (diesel engine) is working, the belt pulley and the belt are arranged to drive the gearbox 13 and the hydraulic oil pump 16 to work and thus provide power.

[0073] When the diesel engine of the power assembly 12 is working, the belt pulley and the belt drive the gearbox 13 to work, the output shaft of the gearbox 13 drives the input shaft of the steering gear 2 to rotate through the universal joint coupling 21, and then the output shaft of the steering gear 2 drives the transmission sleeve 22 to rotate, the transmission sleeve 22 drives the transmission shaft 31 to rotate when rotating, the transmission shaft 31 drives the sliding sleeve 51 to rotate, the sliding sleeve 51 drives the transmission gear 53 to rotate, the transmission gear 53 drives the connecting sleeve 52 to rotate, and the connecting sleeve 52 drives the drill rod to rotate (the drill rod is fixedly connected to the connecting sleeve 52). Thus, through a series of transmissions, the gearbox 13 drives the drill rod to rotate.

[0074] When drilling a straight hole, the rotary head 5 is raised to the top of the mast 3 by operating the hydraulic control valve connected to the hydraulic oil pump 16 to control the extension of the first lifting cylinder 41. When the extension end of the first lifting cylinder 41 is extended, the cylinder body of the first lifting cylinder 41 rises along the guide sleeve 40, and the rotary head 5 is raised by the first lifting cylinder body 41. When drilling, the extension end of the first lifting cylinder 41 is retracted, the rotary head 5 is lowered by the first lifting cylinder body 41, and the sliding sleeve 51 slides downward along the transmission shaft 31. It should be noted that when the transmission shaft 31 rotates, the sliding sleeve 51 slides downward along the transmission shaft 31 and rotates, so that the rotary head 5 rotates while descending, achieving drilling construction. In addition, during the lifting of the first lifting cylinder 41, the sliding guide cooperation of the sliding seats 43 and 42 can limit and guide the lifting of the first lifting cylinder 41, avoid the hole position deviation of the drill pipe, and improve the stability of the device.

[0075] When drilling an inclined hole, the extension end of the second lifting cylinder is retracted by operating the hydraulic control valve connected to the hydraulic oil pump 16, the second lifting cylinder generates a pulling force on the mast 3, and the mast 3 rotates around the rotary support 11 as the pivot. When the appropriate inclination angle is reached, the retraction of the extension end of the second lifting cylinder is stopped, so that the drill pipe is in an inclined state. Subsequently, the drill pipe is rotated by the gearbox 13, and the rotary head 5 is raised and lowered by the first lifting cylinder 41 to achieve inclined drilling. In addition, when drilling an inclined hole, the extension end of the fourth lifting cylinder 94 is extended by operating the hydraulic control valve connected to the hydraulic oil pump 16 when the long adjustable foot support frame 9 is used. The inner tube body 921 of the inner frame 92 of the top support is extended from the sleeve 911 of the outer frame 91, and the top pin plate 93 is pressed against the ground. When the short adjustable foot support frame 9 is used, the adjusting screw 97 is rotated, the bottom end of the adjusting screw 97 moves downward, the channel steel plate 98 moves downward, and the limiting rod 99 moves downward from the bottom of the limiting tube 95, so that the top pin plate 93 is pressed against the ground. This can avoid the swing of the mast 3 during inclined hole operation and the deviation of the drilling hole position, and improve the reliability of the device.

[0076] In this embodiment, the winch 14 is connected to the lifting device 83 through the steel wire rope 15, which can meet the needs of drop hammer and impact drilling. When it is necessary to adjust the height of the crown block 8, the extension end of the third lifting cylinder 33 is extended by operating the hydraulic control valve connected to the hydraulic oil pump 16, and the third lifting cylinder 33 generates a pushing force on the upper mast 81. Under the action of the pushing force, the upper mast 81 rises upward along the guide pipe 32, and the crown block 8 is raised. When the desired height is reached, the positioning pin is inserted into the through pin hole 811. It should be noted that at this time, a plurality of through pin holes 811 will be exposed from the top of the guide pipe 32. The positioning pin and the through pin hole 811 can limit and fix the position of the upper mast 81, and can also avoid continuous stress on the third lifting cylinder 33.
