Description

Technical Field

[0001] This invention relates to the field of drilling, and in particular to a front-tracked rear-wheel-driven drilling equipment and its construction method. Background Technology

[0002] In the aftermath of earthquakes and landslides, conventional geological exploration equipment, both domestically and internationally, is bulky and weighs several tons. On-site investigations rely solely on geophysical exploration, remote sensing, and UAV photogrammetry, making it impossible to obtain detailed stratigraphic structures and geotechnical parameters, thus hindering the development of targeted and cost-effective emergency reinforcement plans. Furthermore, post-earthquake and landslide roads are often uneven, with steep slopes and various obstacles. Existing geological exploration equipment struggles to adapt to these rugged terrains, making it difficult to reach the sites and rapidly transport specialized emergency rescue and road maintenance equipment.

[0003] Post-earthquake and landslide geological conditions are complex and diverse. To obtain accurate geological data, post-earthquake geology requires drilling exploration in vertical, horizontal, and even diagonal directions. Horizontal drilling is for hazard detection and does not require core sampling analysis. Vertical drilling, however, requires complete core samples to test lithology, density, and water content. Horizontal drilling does not require core sampling and lacks core tube adapters, while vertical drilling does require core sampling and necessitates the use of hollow drill rods. Different drilling directions place different requirements on the drilling rig's power head, necessitating different speeds, cuttings removal capabilities, and speed-power matching to ensure that different power heads are needed for vertical and horizontal directions. Existing drilling equipment cannot easily switch between different power heads from the guide frame, thus limiting its functionality to vertical drilling exploration and failing to cover geological exploration tasks in horizontal and diagonal directions. Summary of the Invention

[0004] This invention provides a front-tracked, rear-wheel-driven drilling equipment and its construction method, which solves the problem of uneven road surfaces after earthquakes and landslides, steep slopes, and various obstacles, making it difficult for existing geological exploration equipment to adapt to rugged roads and enabling the rapid delivery of emergency rescue and road maintenance equipment to the work site.

[0005] Another problem solved by this invention is that geological conditions after an earthquake require drilling exploration in vertical, horizontal, and even inclined directions. Different drilling directions have different requirements for the power head of the drilling rig. Existing drilling equipment is difficult to replace with different power heads from the guide frame and can only drill in the vertical direction, resulting in a single function.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a front-tracked and rear-wheeled transport drilling construction equipment and its construction method, including a chassis, a front suspension mechanism and a steering mechanism respectively provided at both ends of the chassis, lifting track wheels provided on both sides of the front suspension mechanism, a rear suspension mechanism provided at the bottom of the steering mechanism, a portable drilling rig provided on the chassis, the portable drilling rig including a drilling base, and a rotating guide frame provided on the drilling base.

[0007] In the preferred embodiment, the guide frame has a U-shaped structure, and a feed cylinder is installed inside the U-shaped structure of the guide frame. A power head is installed at one end of the feed cylinder, and the power head slides against the guide frame. A telescopic auxiliary tower is installed on the guide frame, and a winch is installed at one end of the drill base.

[0008] In a preferred embodiment, a vertical support plate is provided at one end of the drill base, and one end of the support plate is hinged to the guide frame. A hinge seat is provided in the middle of the drill base, and a variable amplitude cylinder and a stabilizing cylinder are rotatably connected on the hinge seat. Both the variable amplitude cylinder and the stabilizing cylinder are hinged to the guide frame.

[0009] In the preferred embodiment, the guide frame has multiple sleeves on both sides, and bolt holes are provided on the sleeves. The secondary tower includes two sliding columns that slide against the sleeves. The secondary tower includes two rollers at the top, and the winch's steel cable is connected to the power head through the rollers.

[0010] In the preferred embodiment, the power head includes a sliding seat at the bottom, and limiting plates are provided on both sides of the U-shaped structure of the guide frame. The sliding seat slides against the two limiting plates, and a connecting flange is provided at one end of the feed cylinder. The connecting flange is connected to the sliding seat.

[0011] In a preferred embodiment, the front suspension mechanism includes two T-shaped hinged bases. Each base has two hinged upper swing arms and two hinged lower swing arms on both sides. The hinged bases are hinged to the upper and lower swing arms. A connecting rod is provided between the two lower swing arms on one side. A suspension cylinder is provided between the connecting rod and the base. The hinged bases are rotatably connected to the track wheels.

[0012] In a preferred embodiment, the track wheel includes a support frame and a track. The support frame is provided with a drive wheel, a tension wheel and multiple support wheels. The support frame is provided with a hinge hole, which is connected to the front suspension mechanism. A tensioning cylinder is provided between the support frame and the tension wheel. A motor is provided on one side of the drive wheel.

[0013] In a preferred embodiment, the steering mechanism includes a second base, on which a slewing mechanism is mounted. The slewing mechanism is rotatably connected to the chassis. The rear suspension mechanism includes a crossbeam and a balance beam. Both ends of the crossbeam are rotatably connected to the second base and the balance beam, respectively. A second cylinder is mounted between the crossbeam and the second base. Rear wheel sets are mounted on both sides of the balance beam.

[0014] In the preferred embodiment, the chassis is equipped with a power unit, a drone, a positioning system, multiple drill rods, multiple anchor rods, and multiple seats. The positioning system includes an integrated monitoring system.

[0015] A construction method for a front-tracked and rear-wheeled drilling construction equipment, characterized by: S1, determining the route: rescue personnel use drones and positioning systems to investigate the surface conditions, and select a suitable starting point and determine a route based on the parameters of the overall device and the drilling location, such as the maximum slope and turning radius; S2, drive the rear wheel assembly and track wheels to start moving. During the forward movement, the chassis overturning stability is monitored by the integrated monitoring system. When the overturning stability coefficient is less than 1.2, manual intervention is required. S3. By adjusting the front and rear suspension mechanisms, the overall structure is prevented from overturning, and the deviation between the driving trajectory and the planned path is continuously corrected. S4. If the obstacle encountered reaches the limit performance of the transport platform, drive the steering mechanism to adjust the overall heading of the device to avoid the obstacle; dispatch a drone to re-explore and provide a new path. S5. Overall positioning: After reaching the designated position, drive the luffing cylinder and stabilizing cylinder to make the guide frame vertical. The power head clamps the anchor rod and drills vertically. After drilling is completed, release the anchor rod and the chassis moves forward. The anchor rod is connected to the chassis by an iron chain. S6. Vertical drilling: The drill rod is held by the power head, and the power head and feed cylinder are driven to drill holes; S7. Replace the horizontal drilling power head: After manually pulling out the auxiliary tower and fixing the bolts, remove the flange of the power head and the feed cylinder, drive the winch, the power head is separated from the guide frame, replace the horizontal drilling power head, slowly drive the winch, the horizontal power head slides from the top of the guide frame, and the power head is connected to the feed cylinder. S8. Inclined or horizontal drilling: The horizontal power head is connected to the drill rod. Adjust the tilt angle of the amplitude-changing cylinder and the stabilizing cylinder to make the horizontal drilling power head drill.

[0016] The beneficial effects of this invention are as follows: When encountering rough terrain, the integrated monitoring system on the chassis detects the horizontal tilt angle of the chassis and drives the suspension cylinders on both sides of the front suspension mechanism to reduce the horizontal tilt angle measured by the integrated monitoring system. Similarly, the integrated monitoring system detects the longitudinal tilt angle of the chassis and adjusts the height of the front end of the chassis by raising and lowering two suspension cylinders. It also adjusts the height of the rear end of the chassis by driving the second cylinder of the rear suspension mechanism. Through the two suspension cylinders and the second cylinder, the longitudinal tilt angle measured by the integrated monitoring system is reduced, allowing the two tracked wheels to adapt to rough terrain after an earthquake, enabling the overall structure to overcome obstacles and adapt to rough terrain after an earthquake.

[0017] The overall structure is adaptable to complex terrain and harsh environmental conditions, enabling rapid transportation of drilling rigs, drill rods, control consoles, operators, and auxiliary equipment to designated exploration locations. It obtains accurate stratigraphic structure and geomechanical parameters, improving the efficiency of personnel, machinery, and materials access in harsh post-disaster terrain conditions, and enhancing the speed and accuracy of post-disaster stratigraphic information acquisition. The overall structure utilizes a chassis and a portable drilling rig, which is lightweight and can be disassembled and quickly assembled, allowing for the rapid construction of a drilling platform and enabling deep engineering exploration and core drilling. Post-earthquake geological conditions necessitate drilling exploration in vertical, horizontal, and even inclined directions. Different drilling directions place varying requirements on the power head of the drilling rig; the power heads required for vertical and horizontal drilling differ. This application utilizes the luffing cylinder and stabilizing cylinder of a portable drilling rig to adjust the direction of the drill rod on the power head, adapting to vertical, horizontal, or inclined drilling.

[0018] When the power head needs to be replaced, the guide frame is in a vertical position, the auxiliary tower is in an extended position, the feed cylinder is disconnected from the power head, and the winch is driven to disengage the power head's sliding seat from the guide frame. The winch is then slowly moved so that the power head, under manual pushing, rests against one side of the portable drilling rig. The horizontal drilling power head is connected to the winch's cable, and the winch is slowly wound up. When the horizontal drilling power head is raised to one end of the guide frame, its sliding seat rests against the guide frame. The horizontal drilling power head continues to be lowered, and finally, it is connected to the feed cylinder for replacement with a new power head. This overall structure avoids the time-consuming and laborious process of manually lifting the power head. It also avoids the limitation of existing drilling equipment, which is unable to replace different power heads from the guide frame, thus limiting its functionality to vertical drilling and failing to cover horizontal and inclined geological exploration tasks.

Detailed Implementation

[0020] Example 1: like Figure 1-12A front-tracked, rear-wheeled drilling equipment and its construction method are disclosed. The equipment includes a chassis 1, with a front suspension mechanism 2 and a steering mechanism 4 at each end. The front suspension mechanism 2 has lifting track wheels 3 on both sides, and the steering mechanism 4 has a rear suspension mechanism 5 at its bottom. A portable drilling rig 7 is mounted on the chassis 1, including a drill base 701 and a rotating guide frame 702. A control unit is mounted on the chassis 1, connected to the front suspension mechanism 2, track wheels 3, steering mechanism 4, rear suspension 5, and rear wheel assembly 6. When encountering rough terrain, an integrated monitoring system on the chassis 1 detects the horizontal tilt angle of the chassis 1 and drives the suspension cylinders 205 on both sides of the front suspension mechanism 2 to adjust the relative height difference between the two track wheels 3 at the bottom of the chassis 1, thereby reducing the horizontal tilt angle measured by the integrated monitoring system. Similarly, the integrated monitoring system detects the longitudinal tilt angle of the chassis 1, adjusts the overall height of the two track wheels 3 by raising and lowering the two suspension cylinders 205, and adjusts the height of the front end of the chassis 1 by driving the second cylinder 502 of the rear suspension mechanism 5 to adjust the height of the rear end of the chassis 1. The two suspension cylinders 205 and the second cylinder 502 reduce the longitudinal tilt angle measured by the integrated monitoring system, so that the two track wheels 3 can adapt to the rugged road surface after the earthquake, and the overall structure can overcome obstacles and adapt to the rugged road surface after the earthquake.

[0021] The overall structure is adaptable to complex terrain and harsh environmental conditions, enabling rapid transportation of drilling rigs, drill rods, control consoles, operators, and auxiliary equipment to designated exploration locations. It obtains accurate stratigraphic structure and geomechanical parameters, improving the efficiency of personnel, machinery, and materials access in harsh post-disaster terrain conditions, and enhancing the speed and accuracy of post-disaster stratigraphic information acquisition. The overall structure comprises a chassis 1 and a portable drilling rig 7, which is lightweight and can be disassembled and quickly assembled, allowing for the rapid construction of a drilling platform and enabling deep engineering exploration and core drilling. Post-earthquake geological conditions require drilling exploration in vertical, horizontal, and even inclined directions. Different drilling directions place different requirements on the power head of the drilling rig; the power head required for vertical and horizontal drilling is different. This application uses the variable amplitude cylinder 703 and stabilizing cylinder 704 of the portable drilling rig 7 to adjust the direction of the drill rod 10 on the power head 706, so as to adapt to vertical, horizontal, or inclined drilling.

[0022] When the power head 706 needs to be replaced, the guide frame 702 is in a vertical position, the auxiliary tower 707 is in an extended position, the feed cylinder 705 is disconnected from the power head 706, and the winch 708 is driven to disengage the sliding seat 7061 of the power head 706 from the guide frame 702. Then, the winch 708 is slowly conveyed so that the power head 706, under manual pushing, rests against one side of the portable drilling rig 7. The horizontal drilling power head is connected to the steel cable of the winch 708, and the winch 708 is slowly wound up. When the horizontal drilling power head is raised to one end of the guide frame 702, the sliding seat of the horizontal drilling power head rests against the guide frame 702. The horizontal drilling power head continues to be lowered, and finally, the horizontal drilling power head is connected to the feed cylinder 705 for replacement with a new power head. The overall structure avoids the time-consuming and laborious process of manually lifting the power head 706. To avoid the situation where existing drilling equipment is difficult to replace with different power heads 706 from the guide frame, thus limiting existing drilling equipment to vertical drilling exploration, resulting in a single function and inability to cover geological exploration tasks in the horizontal and inclined directions.

[0023] In the preferred embodiment, the guide frame 702 has a U-shaped structure, and a feed cylinder 705 is installed inside the U-shaped structure of the guide frame 702. A power head 706 is located at one end of the feed cylinder 705, and the power head 706 slides against the guide frame 702. A telescopic auxiliary tower 707 is installed on the guide frame 702, and a winch 708 is located at one end of the drill base 701. This structure, with the guide frame 702 being U-shaped, allows the feed cylinder 705 to be installed inside the guide frame 702, providing space for the feed cylinder 705. The winch 708 and the support plate 7011 are located at opposite ends of the drill base 701.

[0024] In a preferred embodiment, a vertical support plate 7011 is provided at one end of the drill base 701, and one end of the support plate 7011 is hinged to the guide frame 702. A hinge seat 7012 is provided in the middle of the drill base 701, and a variable amplitude cylinder 703 and a stabilizing cylinder 704 are rotatably connected on the hinge seat 7012. Both the variable amplitude cylinder 703 and the stabilizing cylinder 704 are hinged to the guide frame 702. With this structure, the support plate 7011 is located at one end of the drill base 701, so that when the guide frame 702 rotates to a vertical position, the bottom of the power head 706 is located on one side of the drill base 701.

[0025] In a preferred embodiment, the guide frame 702 has multiple sleeves 7021 on both sides, and each sleeve 7021 has bolt holes 7022. The secondary tower 707 includes two sliding columns 7071 that slide against the sleeves 7021. The secondary tower 707 includes two rollers 7072 at the top, and the steel cable of the winch 708 is connected to the power head 706 through the rollers 7072. With this structure, the secondary tower 707 is connected to the sleeves 7021 of the guide frame 702 by bolts, making the installation and disassembly of the guide frame 702 convenient and simplifying the overall structure. The secondary tower 707 can extend and retract relative to the guide frame 702, allowing it to adapt to the height during vertical drilling. Similarly, when the guide frame 702 is horizontal, it retracts to prevent it from impacting the top of the seat 12.

[0026] In a preferred embodiment, the power head 706 includes a sliding seat 7061 at the bottom. Limiting plates are provided on both sides of the U-shaped structure of the guide frame 702. The sliding seat 7061 slides against the two limiting plates. A connecting flange is provided at one end of the feed cylinder 705, and the connecting flange is connected to the sliding seat 7061. With this structure, the vertical power head 706 and the horizontal drilling power head have different speeds, different chip removal function adaptations, and different speed-power matching. The sliding seat 7061 structure is the same for both the vertical power head 706 and the horizontal drilling power head.

[0027] In a preferred embodiment, the front suspension mechanism 2 includes two T-shaped hinged bases 201. Each base 201 has two hinged upper swing arms 202 and two hinged lower swing arms 203 on both sides. The hinged base 204 is hinged to the upper swing arms 202 and lower swing arms 203. A connecting rod is provided between the two lower swing arms 203 on one side. A suspension cylinder 205 is provided between the connecting rod and the base 201. The hinged base 204 is rotatably connected to the track wheels 3. With this structure, the connecting rod at the bottom of the suspension cylinder 205 is connected to the two lower swing arms 203 at the bottom. When the suspension cylinder 205 is driven, the track wheels 3 on both sides rise and fall.

[0028] When encountering rough terrain, the integrated monitoring system on chassis 1 detects the horizontal tilt angle of chassis 1 and drives the suspension cylinders 205 on both sides of the front suspension mechanism 2 to adjust the relative height difference between the two track wheels 3 at the bottom of chassis 1, thereby reducing the horizontal tilt angle measured by the integrated monitoring system.

[0029] In the preferred embodiment, the track wheel 3 includes a support frame 301 and a track 307. The support frame 301 is equipped with a drive wheel 303, a tension wheel 305, and multiple support wheels 304. The support frame 301 has a hinge hole 302, which connects to the front suspension mechanism 2. A tensioning cylinder 306 is provided between the support frame 301 and the tension wheel 305. A motor 308 is provided on one side of the drive wheel 303. With this structure, the overturning stability coefficient is a key indicator for measuring the equipment's anti-tipping ability. The calculation logic is the force that prevents the equipment from overturning divided by the force that causes the equipment to overturn. A coefficient ≥ 1.2 indicates that the equipment has sufficient anti-tipping ability and is in a safe state, requiring no intervention. A coefficient < 1.2 indicates that the anti-tipping ability does not meet the safety standard, and the equipment is at risk of overturning.

[0030] The track wheel 3 and steering mechanism 4 adopt a three-point independent support hydraulic active suspension system. Based on the statically determinate three-point leveling principle and electro-hydraulic proportional adjustment technology, it can quickly respond to changes in the vehicle body posture caused by ground disturbances, maintain vehicle body posture stability, and prevent the vehicle platform from tipping over.

[0031] The track 307 of the track wheel 3 is an inverted trapezoidal rubber track wheel with high obstacle crossing performance. It can adapt to soft ground conditions and cross obstacles with large heights such as boulders and steps. The rear wheel group 6 is equipped with a self-rotating mechanism, which allows the transport platform to turn flexibly with large curvature under complex ground conditions.

[0032] In a preferred embodiment, the steering mechanism 4 includes a second base 401, on which a slewing mechanism is mounted. The slewing mechanism is rotatably connected to the chassis 1. The rear suspension mechanism 5 includes a crossbeam 501 and a balance beam 503. The two ends of the crossbeam 501 are rotatably connected to the second base 401 and the balance beam 503, respectively. A second cylinder 502 is located between the crossbeam 501 and the second base 401. Rear wheel sets 6 are located on both sides of the balance beam 503. With this structure, the slewing mechanism includes a slewing motor, a main bevel gear, and a driven bevel gear. The main bevel gear is connected to the slewing motor, and the driven bevel gear is mounted on the main shaft of the chassis 1. The main bevel gear and the driven bevel gear mesh to drive the slewing motor, causing the slewing mechanism to rotate relative to the chassis 1.

[0033] In the preferred embodiment, the chassis 1 is equipped with a power unit 8, a drone, a positioning system 9, multiple drill rods 10, multiple anchor rods 11, and multiple seats 12. The positioning system 9 includes an integrated monitoring system. With this structure, the auxiliary tower 707 of the portable drilling rig 7 can be retracted. When in a horizontal position, the auxiliary tower 707 retracts to prevent the extended auxiliary tower 707 from hitting the top of the seat 12 and to prevent the guide frame 702 from becoming horizontal.

During the forward movement, the overturning stability of the chassis 1 is monitored by the integrated monitoring system. When the overturning stability coefficient is less than 1.2, manual intervention is required. S3. By adjusting the front suspension mechanism 2 and the rear suspension mechanism 5, the overall structure is prevented from overturning and the deviation between the driving trajectory and the planned path is continuously corrected. S4. If the obstacle encountered reaches the limit performance of the transport platform, drive the steering mechanism 4 to adjust the overall heading of the device to avoid the obstacle; dispatch the drone to explore again and provide a new path. S5. Overall positioning: After reaching the designated position, drive the luffing cylinder 703 and the stabilizing cylinder 704 to make the guide frame 702 vertical. The power head 706 clamps the anchor rod 11 and drills vertically. After drilling is completed, release the anchor rod 11 and the chassis 1 moves forward. The anchor rod 11 is connected to the chassis 1 by an iron chain. S6. Vertical drilling: The drill rod 10 is clamped by the power head 706, and the power head 706 and the feed cylinder 705 are driven to drill. S7. Replace the horizontal drilling power head: After manually pulling the auxiliary tower 707 and fixing it with bolts, remove the flange of the power head 706 and the feed cylinder 705, drive the winch 708, the power head 706 will disengage from the guide frame 702, replace the horizontal drilling power head, slowly drive the winch 708, the horizontal power head will slide from the top of the guide frame 702, and the power head will connect with the feed cylinder 705. S8. Inclined or horizontal drilling: The horizontal power head is connected to the drill rod 10.
