[0001] The invention relates to the technical field of construction machinery, and in particular to a horizontal directional drilling device. Background Art

[0002] Horizontal directional drilling rig is a kind of construction machinery that lays various underground public facilities (pipelines, cables, etc.) without excavating the surface of the ground. It is suitable for sandy soil, clay, and other ground conditions, but not suitable for high groundwater levels and pebble formations. It can be constructed in most non-hard rock areas in my country. Horizontal directional drilling technology is a new construction technology that combines the directional drilling technology of the petroleum industry with traditional pipeline construction methods.

After the frame 2 is adjusted to the set inclination angle by the hydraulic cylinder 5, the distance between the first support plate 22 and the second support plate 25 can be adjusted by the first support rod 23 and the second support rod 24 according to the height from the ground of one end of the first support plate 22 of the frame 2, so that the first support plate 22 and the second support plate 25 can provide a stable supporting force for one end of the frame 2, and a groove is provided above the second support plate 25 at the position corresponding to the second support rod 24, and the second support rod 24 is fixed in the groove. Screw holes 29 are provided on the surfaces of the first support plate 22 and the second support plate 25, and the first support plate 22 and the second support plate 25 are fixed to the ground by passing the screw holes 29 on the first support plate 22 and the second support plate 25 by using anchor rods, so as to limit one end of the device.

[0033] Reference Figure 2 A first stabilizing mechanism is arranged at the other end of the horizontal drilling rig body 1 close to the frame 2. The first stabilizing mechanism comprises a reduction motor 6, which is fixedly connected to the horizontal drilling rig body 1 through a fixing frame 7, and a turntable 8 is connected to the output end of the reduction motor 6, and a screw rod 9 is connected below the turntable 8. A moving column 10 is threadedly assembled on the surface of the screw rod 9, and a cone rod 11 is arranged at the lower end of the moving column 10. A limiting plate 12 is arranged at the position of the moving column 10 at one end of the horizontal drilling rig body 1 corresponding to the moving column 10. The moving column 10 is slidably connected with the limiting plate 12, and the cross-section of the moving column 10 is a rectangular structure. When the screw rod 9 rotates counterclockwise, since the moving column 10 is threadedly assembled with the screw rod 9, and the limiting plate 12 limits the moving column 10, the moving column 10 can drive the cone rod 11 to gradually move downward until the cone rod 11 is inserted into the ground, thereby stabilizing the device.

[0034] Reference Figure 3-5 A second stabilizing mechanism is arranged between the first stabilizing mechanism and the horizontal drilling rig body 1, and the second stabilizing mechanism includes a tooth groove 13 and a fixing member 14. A first push block 19 and a second push block 21 are respectively arranged at the two ends of the surface of the turntable 8 near the tooth groove 13. A rotating shaft 15 is rotatably connected between the two fixing members 14. A back plate 16 is sleeved on the surface of the rotating shaft 15, and an incomplete gear 17 is fixedly connected to one end of the rotating shaft 15. A tooth 30 matching with the tooth groove 13 is arranged on the surface of the incomplete gear 17. The meshing action of the tooth 30 and the tooth groove 13 can make the incomplete gear 17 rotate, thereby realizing the flipping of the back plate 16. A first round rod 18 matching with the first push block 19 and a second round rod 20 matching with the second push block 21 are respectively arranged on one side of the incomplete gear 17.

[0035] Reference Figure 3 and Figure 5 The surface of the incomplete gear 17 is symmetrically fixed with limiting teeth 31, which cooperate with the teeth 30 to limit the incomplete gear 17 and prevent the abutment plate 16 from accidentally turning over.

[0036] Reference Figure 3 and Figure 6 , hollow blocks 32 are fixed at the positions corresponding to the first push block 19 and the second push block 21 above the turntable 8, the first push block 19 and the second push block 21 are respectively slidably connected to the two hollow blocks 32, and buckles are provided on the upper part of the hollow blocks 32. The surfaces of the first push block 19 and the second push block 21 are provided with slots at the positions corresponding to the buckles. The first push block 19 and the second push block 21 are pulled upward, and the slots of the first push block 19 and the second push block 21 are respectively engaged with the buckles in the corresponding hollow blocks 32, so that the heights of the first push block 19 and the second push block 21 can be fixed, so that the first push block 19 and the second push block 21 can touch the first round rod 18 and the second round rod 20 respectively.

[0037] In the present invention, after the horizontal drilling rig body 1 is moved to the specified position, the hydraulic cylinder 5 is used to adjust the frame 2 to the set inclination angle, and the distance between the first support plate 22 and the second support plate 25 is adjusted according to the height from the ground of one end of the frame 2 where the first support plate 22 is located. The first support plate 22 and the second support plate 25 are first rotated so that the bottom surface of the second support plate 25 can be in contact with the ground, and the screw rod 27 is loosened by the knob 28 to make the first support rod 23 slide in the second support rod 24 to change the total length of the first support rod 23 and the second support rod 24, and then the screw rod 27 is tightened to lock the total length of the first support rod 23 and the second support rod 24, so that the first support plate 22 and the second support plate 25 can provide stable supporting force for one end of the frame 2. Finally, the anchor rod can be used to pass through the screw holes 29 on the first support plate 22 and the second support plate 25 to fix the first support plate 22 and the second support plate 25 to the ground.

[0038] The second push block 21 is pulled upward until the slot of the second push block 21 is engaged with the buckle in the corresponding hollow block 32, so that the height of the second push block 21 can be fixed. At this time, the tooth 30 is located on the right side, and a section between the tooth 30 on the side of the incomplete gear 17 and one of the limit teeth 31 is located directly above the side of the turntable 8. The lower end of the abutment plate 16 does not contact the ground to facilitate the movement of the device. Then, the reduction motor 6 is started, and the reduction motor 6 drives the turntable 8 to rotate counterclockwise until the second push block 21 contacts the second round rod 20 and causes the incomplete gear 17 to rotate slightly, and the tooth 30 is able to mesh and rotate with the tooth groove 13. At this time, the incomplete gear 17 rotates clockwise (such as Figure 3-5 As shown), one end of the abutment plate 16 is tilted downward until it abuts against the ground. After the second push block 21 touches the second round rod 20 once, the second push block 21 is quickly pressed into the corresponding hollow block 32, which can temporarily prevent the incomplete gear 17 from rotating. The tooth 30 and one end of one of the limiting teeth 31 are close to the upper end surface of the side of the turntable 8, which limit the incomplete gear 17, so that the abutment plate 16 can be stably against the ground, and the reduction motor 6 continues to drive the screw rod 9 to rotate counterclockwise. Since the moving column 10 is threadedly assembled with the screw rod 9, and the limiting plate 12 limits the moving column 10, the moving column 10 can drive the cone rod 11 to gradually move downward until the cone rod 11 is inserted into the ground, which further stabilizes the device.

[0039] When it is necessary to move the device again, the anchor rod can be removed, and then the first push block 19 can be pulled upward until the slot of the first push block 19 is engaged with the buckle in the corresponding hollow block 32, so that the height of the first push block 19 can be fixed, and then the reduction motor 6 is started again, and the reduction motor 6 drives the turntable 8 to rotate clockwise until the first push block 19 contacts the first round rod 18 and causes the incomplete gear 17 to rotate slightly, and the tooth 30 is able to mesh and rotate with the tooth groove 13 again. At this time, the incomplete gear 17 rotates counterclockwise, so that one end of the abutment plate 16 is flipped upward and reset, and no longer After the first push block 19 contacts the first round rod 18 once, the first push block 19 is quickly pressed into the corresponding hollow block 32 to temporarily prevent the incomplete gear 17 from rotating. The tooth 30 and one end of one of the limiting teeth 31 are close to the upper end surface of the side of the turntable 8, which limits the incomplete gear 17, so that the abutment plate 16 can stably maintain the current state, and the reduction motor 6 continues to drive the screw rod 9 to rotate clockwise. Similarly, the moving column 10 can drive the cone rod 11 to gradually move upward. When the cone rod 11 is separated from the ground, the device can be moved smoothly.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
