However, in the actual drilling operation, the drill rod is hoisted or manually assisted to install, which not only increases the workload of the operator, but also prolongs the docking and disassembly time of the drill rod, and ultimately reduces the operating efficiency of the drilling operation.

[0024] 4. In this solution, a high-pressure spray gun is used to spray high-pressure water onto a single drill pipe to flush out the mud attached to the circumferential surface of the drill pipe, thereby cleaning the mud on the surface of the drill pipe, preventing the mud from condensing on the circumferential surface of the drill pipe, preventing oxidation and corrosion of the drill pipe, and improving the service life of the drill pipe.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] Reference Figure 1 - Figure 10 , a horizontal directional drilling rig, comprising:

[0040] Drilling rig platform 1;

[0041] Feed assembly 2, which is installed and fixed on the top of the drilling rig platform 1;

[0042] A tilt box 3 is fixedly connected to the top of the drilling rig platform 1 and is parallel to one side of the feed assembly 2. A deflection frame 16 is rotatably connected between the inner walls of the tilt box 3. A drill rod 36 is accommodated in a groove at the top of the deflection frame 16; and

[0043] The loading and unloading mechanism is arranged between the feed assembly 2 and the tilting box 3, and the loading and unloading mechanism is connected to the deflection frame 16 to move the drill rod 36.

[0044] In the present invention, the drilling rig platform 1 is used to support the fixed feed assembly 2, the tilting box 3, the rod box 21 and the cleaning box 22. The feed assembly 2 is used to feed the drill rod and the drill bit. The tilting box 3 is used to accommodate the deflection frame 16 and the pushing assembly, the connecting rod assembly and the guide assembly. The inner wall width of the tilting box 3 can only accommodate one drill rod 36. The deflection frame 16 is used to support and deflect a single drill rod 36. The loading and unloading mechanism is connected to the deflection frame 16 to move the drill rod 36.

[0045] The loading and unloading mechanism includes a pushing assembly, a connecting rod assembly, a guiding assembly, a deflecting assembly, a rod loading assembly and a rod stripping assembly. The connecting rod assembly is arranged between the inner walls of the tilting box 3, and the connecting rod assembly is connected to the deflection frame 16. The pushing assembly is arranged between the inner walls of the tilting box 3, and the pushing assembly is connected to the connecting rod assembly. The guiding assembly is arranged between the inner walls of the tilting box 3, and the guiding assembly is connected to the pushing assembly. The deflecting assembly is arranged at the side end of the feed assembly 2, and the deflecting assembly corresponds to the deflection frame 16. The rod loading assembly is arranged at the side end of the tilting box 3, and the rod loading assembly is connected to the deflection frame 16. The rod stripping assembly is arranged between the inner walls of the tilting box 3, and the rod stripping assembly is connected to the deflection frame 16.

[0046] In the present invention, the connecting rod assembly is used to push the deflection frame 16 and the single drill rod 36 for deflection, the pushing assembly is used to provide power to the connecting rod assembly, the guiding assembly is used to guide the pushing assembly, the deflection assembly is used to move the single drill rod 36, the rod loading assembly is used to move the single drill rod 36, and the rod removing assembly is used to push the single drill rod 36 into the cleaning box 22.

[0047] The pushing assembly includes an extending rotating rod 4, a screw rod 5, a rotating motor 6, a slider 7 and a blocking block 10. The screw rod 5 is rotatably connected between the inner walls of the tilting box 3. One end of the screw rod 5 extends to the side end of the tilting box 3. The rotating motor 6 is fixedly connected to the side end of the tilting box 3. The output end of the rotating motor 6 is fixedly connected to the extended section of the screw rod 5. The blocking block 10 is fixedly connected to the other end of the screw rod 5. The extending rotating rod 4 is rotatably connected between the inner walls of the tilting box 3, and the extending rotating rod 4 is fixedly connected to the blocking block 10. The slider 7 is sleeved on the circumferential surface of the screw rod 5.

[0048] The cam 7 is rotated to move the slider 7 back and forth between the inner wall of the tilting box 3 and the outer wall of the tilting box 3, and the cam 7 is rotated to move the slider 7 back and forth between the inner wall of the tilting box 3 and the inner wall of the tilting box 3. The cam 7 is rotated to drive the cam 5 to rotate, and the blocking block 10 is used to block the movement of the slider 7. The extended rotating rod 4 is used to auxiliary support the blocking block 10 and the cam 5. The slider 7 is used to support and fix the lower adapter block 11 and the two limit blocks 9. During the deflection of the deflection frame 16, the rotating motor 6 is powered on and started. The output end of the rotating motor 6 drives the cam 5, the extended rotating rod 4 and the blocking block 10 to rotate. The cam 5 pushes the slider 7 to move back and forth in the tilting box 3 through the sliding cooperation with the slider 7, and then provides power for the deflection of the deflection frame 16 and the single drill rod 36. The self-locking function of the cam 5 and the slider 7 is used to lock the deflection angle of the deflection frame 16, so that the deflection frame 16 can smoothly deflect and lift the single drill rod 36, thereby preventing the drill rod 36 from falling off from the top groove of the deflection frame 16.

[0049] The connecting rod assembly includes a lower adapter block 11, a push-pull rod 12 and an upper adapter block 14. The lower adapter block 11 is fixedly connected to the top of the slider 7, the upper adapter block 14 is fixedly connected to the bottom of the deflection frame 16, and the push-pull rod 12 is rotatably connected between the lower adapter block 11 and the upper adapter block 14.

[0050] In the present invention, the lower adapter block 11 is used to push the push-pull rod 12 to move, the infrared laser locator 13 is used to support the fixed deflection frame 16, the push-pull rod 12 is used to push and pull the infrared laser locator 13, and then realize the deflection movement of the deflection frame 16. In the deflection process of the single drill rod 36, the slider 7 pushes the lower adapter block 11 to approach the blocking block 10, the lower adapter block 11 pushes the push-pull rod 12 to approach the blocking block 10, the push-pull rod 12 pushes the upper adapter block 14 to lift, and the upper adapter block 14 drives the deflection frame 16 to tilt. The drill rod 36 is deflected between the inner walls of the tilt box 3, and the single drill rod 36 on the top of the deflection frame 16 is lifted to the top of the tilt box 3, so that the drill rod 36 is affected by its own weight and slides toward the rotating shaft end of the deflection frame 16 in the groove of the deflection frame 16, so that the drill rod 36 can be accurately docked with the drill rod 36 drilled into the soil after deflection, avoiding the slippage or collision deformation caused by the misaligned docking between the two drill rods 36, extending the service life of the drill rod 36, reducing the wear of the drill rod by the horizontal directional drilling rig, and reducing the maintenance and use cost of the horizontal directional drilling rig.

[0051] The guiding assembly includes a limit groove 8, a limit block 9 and an infrared laser locator 13. There are two limit grooves 8, which are opened at the two side ends of the tilting box 3. The two limit grooves 8 are connected to the inner wall of the tilting box 3. There are two limit blocks 9, which slide between the inner walls of the two limit grooves 8. The two limit blocks 9 are connected to the slider 7. The infrared laser locator 13 is fixedly connected to the side end of the slider 7, and the infrared laser locator 13 is located on the lower side of the screw rod 5.

[0052] In the present invention, the two limit grooves 8 are used to accommodate the sliding of the two limit blocks 9. The two limit blocks 9 guide the movement of the slider 7 by sliding with the two limit grooves 8. The infrared laser locator 13 is used to emit infrared laser to the inner wall of the tilting box 3 to detect the moving distance of the slider 7 in real time, and then match the deflection angle of the deflection frame 16 to detect the deflection angle of the deflection frame 16 in real time. By setting the moving range of the slider 7, the deflection angle of the deflection frame 16 is limited to a range, and then the deflection frame 16 is prevented from being pushed out of the tilting box 3, ensuring that the drill rod 36 lifted by the deflection frame 16 has the same inclination angle as the drill rod 36 on the feed assembly 2, thereby realizing the tilt positioning of the single drill rod 36.

[0053] The deflection assembly includes a mounting frame 30, a rotating rod 31, a stepper motor 32, a deflection shaft 33 and a C-shaped magnetic block 34. The mounting frame 30 is fixedly connected to the side end of the feed assembly 2, the rotating rod 31 is rotatably connected between the inner walls of the mounting frame 30, one end of the rotating rod 31 extends to one end of the mounting frame 30, the stepper motor 32 is fixedly connected to the side end of the mounting frame 30, the output end of the stepper motor 32 is fixedly connected to the extended end of the rotating rod 31, two deflection shafts 33 are provided, and the two deflection shafts 33 are fixedly connected to the circumferential surface of the rotating rod 31, and two C-shaped magnetic blocks 34 are provided, and the two C-shaped magnetic blocks 34 are fixedly connected to the extended ends of the two deflection shafts 33.

[0054] In the present invention, the mounting frame 30 is used to support and fix the rotating rod 31 and the stepper motor 32. The rotating rod 31 is used to support and fix the two deflection shafts 33. The stepper motor 32 is used to drive the rotating rod 31 to rotate, thereby deflecting the two deflection shafts 33. The two C-shaped magnetic blocks 34 are used to magnetically move a single drill rod 36. When the single drill rod 36 is docked and installed, when the deflection frame 16 deflects to the uppermost end of the tilting box 3, the slider 7 triggers the stepper motor 32 to be powered on and started. The output end of the stepper motor 32 drives the rotating rod 31 to rotate clockwise. The rotating rod 31 drives the two deflection shafts 33 to deflect toward the deflection frame 16, so that the two C-shaped magnetic blocks 34 fit with the drill rod 36. The two C-shaped magnetic blocks 34 are powered on and started. The two C-shaped magnetic blocks 34 magnetically fix the single drill rod 36 on the upper side of the deflection frame 16, and then the stepper motor 32 is powered on and started again. The output end of the stepper motor 32 drives the rotating rod 31 to rotate counterclockwise, and the rotating rod 31 drives the two deflection shafts 33 to deflect and reset. The two C-shaped magnetic blocks 34 drive the drill rod 36 to reset, and move the drill rod 36 to the top of the feed assembly 2, so that the drill rod 36 is connected to the drill rod 36 inserted into the soil, and then the feed assembly 2 threadedly connects the two drill rods 36. The mechanical structure replaces the drill rod hoisting or manual assisted movement of the drill rod during drill rod docking, thereby reducing the workload of the operator and shortening the docking and disassembly time of the drill rod, thereby ultimately improving the operating efficiency of the drilling operation.

[0055] The rod mounting assembly includes a docking groove 20, a rod box 21 and a baffle 15. The docking groove 20 is opened on one side of the tilting box 3, and the docking groove 20 is connected to the tilting box 3. The rod box 21 is fixedly connected to the top of the drilling rig platform 1, and the rod box 21 corresponds to the docking groove 20. The baffle 15 is fixedly connected to the side end of the deflection frame 16. The baffle 15 is located between the inner walls of the tilting box 3, and the baffle 15 corresponds to the docking groove 20.

[0056] In the present invention, the docking groove 20 is used to introduce the drill rod 36 in the rod box 21 into the tilting box 3, and the rod box 21 is used to accommodate the stacking of multiple drill rods 36. The baffle 15 uses the tilt to block the drill rod 36 in the rod box 21 from entering the tilting box 3. At the same time, the baffle 15 is used to limit the unidirectional movement of the drill rod 36 from the rod box 21 into the tilting box 3. When a single drill rod 36 is moved from the rod box 21 to the deflection frame 16, the deflection frame 16 is pressed down below the docking groove 20 to avoid the baffle 15 blocking the docking groove 20, so that the drill rod 36 in the rod box 21 can move from the docking groove 20 to the top groove of the deflection frame 16, and then when the deflection frame 16 deflects upward, the baffle 15 blocks the docking groove 20, making it convenient for the single drill rod 36 to quickly enter the groove of the deflection frame 16, thereby realizing the horizontal directional drilling rig to install a single drill rod 36.

[0057] The rod-dropping assembly includes a lifting slot 17, a first electric push rod 18 and an inclined block 19. The lifting slot 17 is opened at the top of the deflection frame 16. The inclined block 19 slides between the inner walls of the lifting slot 17. The first electric push rod 18 is fixedly connected to the bottom of the deflection frame 16. The output end of the first electric push rod 18 extends between the inner walls of the lifting slot 17, and the output end of the first electric push rod 18 is fixedly connected to the inclined block 19.

[0058] In the present invention, the lifting groove 17 is used to accommodate the inclined block 19, and the top of the inclined block 19 is unilaterally inclined. The inclined block 19 is used to push the drill rod 36 at the top of the deflection frame 16 into the cleaning box 22. The first electric push rod 18 is used to lift the inclined block 19. When the drill rod 36 at the top of the deflection frame 16 needs to be sent into the cleaning box 22, the first electric push rod 18 is powered on and started. The output end of the first electric push rod 18 extends to lift the inclined block 19, and then pushes the inclined block 19 out of the lifting groove 17, so that the inclined block 19 pushes the drill rod 36 into the cleaning box 22 in one direction, thereby realizing the rapid dumping of a single drill rod 36.

[0059] A cleaning box 22 is fixedly connected to the top of the drilling rig platform 1. The cleaning box 22 is located between the tilting box 3 and the feed assembly 2. A slurry discharge port 26 is provided at one end of the cleaning box 22, and a rod outlet 29 is provided at the other end of the cleaning box 22. An inclined plate 25 is fixedly connected between the inner walls of the cleaning box 22. A mounting block 23 is fixedly connected between the inner walls of the cleaning box 22. A high-pressure spray gun 24 is installed on the top of the mounting block 23, and the spray end of the high-pressure spray gun 24 extends to the bottom of the mounting block 23.

[0060] In the present invention, the cleaning box 22 is used to accommodate the disassembled drill rod 36, the slurry outlet 26 is used to guide the muddy water out of the cleaning box 22, the rod outlet 29 is used to guide the cleaned drill rod 36, the inclined plate 25 is used to guide the unidirectional flow of water, and at the same time the inclined plate 25 is used to guide the single drill rod 36 to move toward the rod outlet 29, the mounting block 23 is used to support and fix the high-pressure spray gun 24, the high-pressure spray gun 24 is used to spray high-pressure water flow to the single drill rod 36, flushing the mud attached to the circumferential surface of the drill rod 36, thereby cleaning the mud on the surface of the drill rod 36, avoiding the mud from condensing on the circumferential surface of the drill rod 36, preventing the drill rod 36 from oxidation and corrosion, and improving the service life of the drill rod 36.

[0061] Two guide protrusions 35 are provided between the inner walls of the cleaning box 22. The two guide protrusions 35 are located on both sides of the slurry discharge outlet 26. One end of the cleaning box 22 is fixedly connected to a second electric push rod 27. The output end of the second electric push rod 27 extends to between the inner walls of the cleaning box 22. The output end of the second electric push rod 27 is fixedly connected to a push block 28, and the push block 28 is located between the two guide protrusions 35.

[0062] In the present invention, the two guide protrusions 35 are used to guide the flushed mud to the slurry water outlet 26, the second electric push rod 27 is used to push and pull the push block 28, and the push block 28 is used to push the drill rod 36 between the two guide protrusions 35 to the rod outlet 29. After the drill rod 36 falls off into the cleaning box 22, the second electric push rod 27 is powered on and started. The output end of the second electric push rod 27 extends to push the single drill rod 36 to slide into the rod outlet 29, thereby pushing the single drill rod 36 out of the rod outlet 29 and providing power for the movement of the single drill rod 36. At the same time, when the output end of the second electric push rod 27 contracts, the push block 28 is pushed to the slurry water outlet The opening 26 moves closer, and the push block 28 pushes out the mud deposited between the two guide protrusions 35, so that the deposited mud flows out from the slurry discharge opening 26, avoiding the mud in the cleaning box 22 blocking the guidance of the drill rod 36 by the two guide protrusions 35, so that the push block 28 can correspond to the single drill rod 36, avoiding the misalignment between the push block 28 and the slurry discharge opening 26, resulting in the accumulation of multiple drill rods 36 in the cleaning box 22, and then making the accumulation of multiple drill rods 36 in the cleaning box 22 unable to be pushed out, eliminating the accumulation of multiple drill rods 36 in the cleaning box 22, so that the drill rods 36 in the cleaning box 22 can be quickly moved out.

[0063] A method for using a horizontal directional drilling rig comprises the following steps:

[0064] S1, Single supply:

[0065] When the baffle 15 is in the tilting box 3 and the baffle 15 blocks the docking groove 20, multiple drill rods 36 are stacked in the rod box 21, and the rotating motor 6 is powered on and started. The output end of the rotating motor 6 drives the screw rod 5, the blocking block 10 and the extending rotating rod 4 to rotate. The screw rod 5 pulls the lower adapter block 11 close to the rotating motor 6 through the sliding cooperation with the slider 7. The lower adapter block 11 pulls the push-pull rod 12, and the push-pull rod 12 pulls the upper adapter block 14. The upper adapter block 14 drives the deflection frame 16 to press down, so that the baffle 15 is located at the lower side of the docking groove 20, which facilitates the single drill rod 36 in the rod box 21 to enter the tilting box 3 from the docking groove 20, and the single drill rod 36 is located in the top groove of the deflection frame 16, realizing the single supply of the drill rod 36;

[0066] S2, deflection and lifting:

[0067] After the drill rod 36 is supplied to the top groove of the deflection frame 16, the rotating motor 6 is powered on and started. The output end of the rotating motor 6 drives the screw rod 5, the blocking block 10 and the extension rotating rod 4 to rotate. The screw rod 5 pushes the slider 7 to move in the tilting box 3 through sliding cooperation with the slider 7, so that the slider 7 pushes the lower adapter block 11 to approach the blocking block 10, and the lower adapter block 11 pushes the push-pull rod 12. The push-pull rod 12 pushes the upper adapter block 14 to lift. The upper adapter block 14 drives the deflection frame 16 to deflect in the tilting box 3, so that the single drill rod 36 in the groove of the deflection frame 16 slides unidirectionally close to the rotating shaft end of the deflection frame 16, and then makes the single drill rod 36 parallel to the drill rod 36 inserted into the soil in the feed assembly 2, thereby realizing the deflection and lifting of the single drill rod 36;

[0068] S3. Magnetic installation:

[0069] After the single drill rod 36 is deflected and lifted, the infrared laser locator 13 detects that the deflection frame 16 and the drill rod 36 are deflected to a suitable angle, which triggers the power-on start of the stepper motor 32. The output end of the stepper motor 32 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the two deflection shafts 33 to deflect, and the two C-shaped magnetic blocks 34 are moved from the feed assembly 2 to the top of the deflection frame 16. The two C-shaped magnetic blocks 34 are fitted with the single drill rod 36, and the two C-shaped magnetic blocks 34 are powered on. The block 34 magnetically fixes the single drill rod 36, and then the stepper motor 32 is powered on again and started. The output end of the stepper motor 32 drives the rotating rod 31 to rotate counterclockwise, and the rotating rod 31 drives the two deflection shafts 33 to deflect and reset. The two C-shaped magnetic blocks 34 drive the drill rod 36 to reset, and move the drill rod 36 to the top of the feed assembly 2, so that the drill rod 36 is connected to the drill rod 36 inserted into the soil. Then the feed assembly 2 performs threaded docking on the two drill rods 36 to achieve magnetic installation of the single drill rod 36;

[0070] S4. Magnetic disassembly:

[0071] The two C-shaped magnetic blocks 34 are located on the lower side of the drill rod 36. After the drilling operation is completed, the threaded connection between the two drill rods 36 is released, and the two C-shaped magnetic blocks 34 electromagnetically attract the single drill rod 36. The stepper motor 32 is powered on and started. The output end of the stepper motor 32 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the two deflection shafts 33 to deflect. The two deflection shafts 33 drive the two C-shaped magnetic blocks 34 to deflect with the rotating rod 31 as the axis, so that the two C-shaped magnetic blocks 34 move the single drill rod 36 into the top groove of the deflection frame 16, thereby realizing the magnetic removal of the single drill rod 36.

[0072] S5, Single root push:

[0073] When a single drill rod 36 with mud is present on the top of the deflection frame 16, the first electric push rod 18 is powered on and started, and the output end of the first electric push rod 18 is extended to push the inclined block 19 out of the lifting groove 17. The inclined block 19 pushes the single drill rod 36 from the top of the deflection frame 16 into the cleaning box 22, and then the second electric push rod 27 is powered on and started, and the output end of the second electric push rod 27 contracts and pulls the push block 28. The push block 28 is between the two guide protrusions 35, pushing the mud in the cleaning box 22 out of the slurry water outlet 26, and at the same time, the push block 28 is located on one side of the slurry water outlet 26, The second electric push rod 27 is powered off and shut down, and then the first electric push rod 18 is powered on and started. The output end of the first electric push rod 18 extends, pushing the inclined block 19 out of the lifting groove 17. The inclined block 19 pushes the single drill rod 36 into the cleaning box 22, so that the single drill rod 36 with mud falls between the two guide protrusions 35. Then the second electric push rod 27 is powered on and started. The output end of the second electric push rod 27 pushes the single drill rod 36 with mud toward the rod outlet 29, so that the drill rod 36 with mud is pushed out from the rod outlet 29, and the drill rod 36 with mud is pushed out individually.

[0074] S6. Cleaning mud:

[0075] When a single drill rod 36 is pushed out, the high-pressure spray gun 24 is powered on and started, and the high-pressure spray gun 24 sprays high-pressure water flow to the drill rod 36 with mud, cleaning the circumferential surface of the single drill rod 36 with mud one by one, thereby cleaning the mud of the single drill rod 36.
