Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a horizontal directional drilling rig. Background Technology

[0002] Horizontal directional drilling rigs are construction machines that lay various underground utilities (pipelines, cables, etc.) without excavating the ground surface. They are widely used in pipeline laying projects for water supply, electricity, telecommunications, natural gas, coal gas, and oil.

[0003] For example, Chinese patent application number CN201821489267.1 discloses a horizontal directional drilling rig, which includes a traveling unit, a drill frame, a first support unit, and a second support unit. The drill frame is placed on the traveling unit; the first support unit is fixed to a fixed object and detachably connected to the first end of the drill frame; the second support unit is fixed to a fixed object and detachably connected to the second end of the drill frame. This drilling rig, through its modular assembly and disassembly design, allows for modular division into several independent units, enabling rapid disassembly and disassembly transportation of the entire machine. This effectively reduces the structural size, facilitating the rapid assembly and disassembly and convenient transportation of heavy equipment, and ensuring that large horizontal directional drilling rigs meet specified transportation requirements. Such drilling rigs are often installed at the rear of a locomotive for flexible drilling. However, in mountainous terrain with large undulations, complex rock distribution, and varying inclination angles, the angle adjustment of these drilling rigs is limited, making it difficult to adapt to changing terrain. For example, when drilling on a hillside, it is often impossible to accurately adjust to the appropriate angle, resulting in the drilling position deviating from the target, increasing construction difficulty and workload.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a horizontal directional drilling rig, including a trolley 1 and a carriage 2 located at the rear of the trolley 1. The carriage 2 is fixedly connected to the trolley 1. A drill arm 4 is provided on the side of the carriage 2 away from the trolley 1, and a drill rod 5 is provided on the drill arm 4.

[0024] The drill arm 4 is equipped with a rotary system and a feed system, both powered by an engine. This ensures the drilling rig can perform operations such as drilling and rotating the drill rod 5. The drill bit is fixedly connected to the bottom of the drill rod 5. During drilling, the rotary system drives the drill rod 5 and the drill bit to rotate, and the cutting edge of the drill bit breaks up rock, soil, and other strata. The drill arm 4 and drill rod 5 are standard drilling components and will not be described in detail here.

[0025] The carriage 2 is equipped with a mechanical adjustment hand 6, which is slidably installed at the bottom of the carriage 2. The upper end of the mechanical adjustment hand 6 is fixedly connected to the drill arm 4 and is used to adjust the drilling angle of the drill arm 4.

[0026] The bottom of the carriage 2 is provided with a sliding mechanism 3 for controlling the horizontal movement of the mechanical adjustment hand 6. The sliding mechanism 3 is rotatably connected to the mechanical adjustment hand 6, and the sliding mechanism 3 is provided with a hydraulic adjustment mechanism for controlling the rotation of the mechanical adjustment hand 6.

[0027] The drill arm 4 is mounted on the carriage 2 at the rear of the trolley 1 via a mechanical adjustment hand 6. During drilling, the trolley 1 pulls the drill arm 4 to a suitable location, and the sliding mechanism 3 pushes the mechanical adjustment hand 6 to move horizontally, sending the drill arm 4 out of the carriage 2. The mechanical adjustment hand 6 adjusts the drilling angle of the drill rod 5 on the drill arm 4, and the hydraulic adjustment mechanism controls the rotation of the mechanical adjustment hand 6 to adjust the drilling direction of the drill arm 4. With multiple angle adjustments, the angle adjustment of the drill arm 4 and the drill rod 5 is flexible, enabling exploration operations in complex terrain and spatial environments, and making it more adaptable.

[0028] Regarding mechanical adjustment arm 6:

[0029] The mechanical adjuster 6 includes a base 61, a support column 62, a second hydraulic push rod 67, and a movable arm 63. The support column 62 is fixedly connected to the upper end of the base 61. One end of the movable arm 63 is hinged to the upper end of the support column 62, and the other end of the movable arm 63 is hinged to a fixed seat 65. The side of the fixed seat 65 away from the movable arm 63 is fixedly connected to the drill rod 5. The support column 62 is provided with a first adjusting device for adjusting the rotation angle of the movable arm 63, and the base 61 is provided with a second adjusting device for adjusting the rotation angle of the fixed seat 65. The mechanical adjuster 6 uses a hydraulic adjustment method to control the drilling angle of the drill arm 4 and the drill rod 5.

[0030] Specifically, the first adjusting device includes a first hydraulic push rod 64, which is positioned at the angle between the movable arm 63 and the support column 62. The mounting end of the first hydraulic push rod 64 is hinged to the support column 62, and the output end of the first hydraulic push rod 64 is hinged to the movable arm 63. When the first hydraulic push rod 64 pushes the movable arm 63, the end of the movable arm 63 connected to the drill arm 4 will lift upwards, and the drill arm 4 will also lift upwards. Conversely, the movable arm 63 pulls the drill arm 4 downwards.

[0031] Specifically, the second adjustment device includes a triangular plate 66, a second hydraulic push rod 67, a first pull rod 68, and a second pull rod 69. The first pull rod 68 is located on one side of the support column 62, and the second pull rod 69 is located on one side of the movable arm 63. The triangular plate 66 is rotatably connected to the upper end of the support column 62. The mounting end of the second hydraulic push rod 67 is hinged to the base 61, and the output end of the second hydraulic push rod 67 is hinged to the lower end of the first pull rod 68. The upper end of the first pull rod 68 is hinged to the triangular plate 66. One end of the second pull rod 69 is hinged to the triangular plate 66, and the other end of the second pull rod 69 is hinged to the fixed seat 65. When the second hydraulic push rod 67 pulls the first pull rod 68, the first pull rod 68 pulls the triangular plate 66, causing the triangular plate 66 to rotate. During the rotation of the triangular plate 66, the second pull rod 69 pulls the fixed seat 65, causing the fixed seat 65 to rotate as well. During the rotation of the fixed seat 65, the drill arm 4 rotates along with it, and the angle between the movable arm 63 and the drill arm 4 increases.

[0032] The mechanical adjuster 6 moves forward and backward using a screw drive. Specifically, the sliding mechanism 3 includes a sliding seat 31, a bracket 34, a motor 35, and a screw 36. The sliding seat 31 is rotatably connected to the lower end of the base 61, the bracket 34 is fixedly connected to the upper end of the carriage 2, the screw 36 is rotatably connected to the inner side of the bracket 34, and the motor 35 is fixedly connected to the outer side of the bracket 34. The output end of the motor 35 is fixedly connected to the screw 36, and a nut seat is fitted on the outer side of the screw 36, which is fixedly connected to the lower end of the sliding seat 31. The motor 35 controls the rotation of the screw 36. During rotation, the screw 36 engages with the nut seat, causing the sliding seat 31 to move horizontally along the shaft of the screw 36 within the carriage 2.

[0033] It is worth explaining in detail that at least two guide rails 32 are laid at the bottom of the carriage 2. The guide rails 32 are fixedly connected to the carriage 2. A slider 33 is provided on the guide rail 32. The slider 33 is fixedly connected to the lower end of the sliding seat 31 and is slidably connected to the guide rail 32. When the sliding seat 31 moves horizontally inside the carriage 2, the slider 33 fixed to the lower end of the sliding seat 31 will move synchronously along the guide rail 32. The guide rail 32, in cooperation with the slider 33, limits the sliding seat 31.

[0034] The hydraulic adjustment mechanism includes a gear 7 housed within a sliding base 31. The gear 7 is fixedly connected to the lower end of a base 61. A toothed plate 72 is located on each of the left and right sides of the gear 7, tangential to and meshing with the gear 7. A third hydraulic push rod 71 is located at the far end of each toothed plate 72. The output end of the third hydraulic push rod 71 is fixedly connected to the toothed plate 72, and the mounting end of the third hydraulic push rod 71 is fixedly connected to the inner side of the sliding base 31. The third hydraulic push rod 7 pushes the toothed plate 72, causing it to mesh with the gear 7. From the left and right sides of the gear 7, the gear 7 is rotated. As the gear 7 rotates, the base 61, fixed to the gear 7, also rotates, thus completing the rotation control of the mechanical adjustment hand 6.

[0035] How this application works:

[0036] The drill arm 4 is equipped with a rotary system and a feed system, both powered by an engine, ensuring the drilling rig can perform operations such as drilling and rotating the drill rod 5. The drill bit is fixedly connected to the bottom of the drill rod 5. During drilling, the rotary system drives the drill rod 5 and the drill bit to rotate, and the cutting edge of the drill bit breaks up rock, soil, and other strata. The drill arm 4 is mounted on the carriage 2 at the rear of the trolley 1 via a mechanical adjustment hand 6. During drilling, after the trolley 1 pulls the drill arm 4 to a suitable location, the sliding mechanism 3 pushes the mechanical adjustment hand 6 to move horizontally, sending the drill arm 4 out of the carriage 2. The mechanical adjustment hand 6 adjusts the drilling angle of the drill rod 5 on the drill arm 4, and the hydraulic adjustment mechanism controls the rotation of the mechanical adjustment hand 6 to adjust the drilling direction of the drill arm 4. With multiple angle adjustments, the angle adjustment of the drill arm 4 and the drill rod 5 is flexible, enabling exploration operations in complex terrain and spatial environments, thus improving its applicability.
