Description

Technical Field

[0001] The present invention relates to the technical field of drilling rigs, and specifically refers to a crawler single-arm drilling rig. Background Art

[0002] In various engineering construction projects, drilling operations are extremely common and crucial. For example, in mining, drilling is required to detect ore bodies and arrange blasting holes; in the early stage of tunnel excavation, geological exploration is carried out through drilling; in building foundation engineering, drilling is used to set up pile foundations, etc.

[0003] However, traditional drilling equipment has many defects. Common wheeled drilling equipment has poor moving stability on complex and rough construction sites, and is prone to jolting and even tipping over, which not only affects the normal operation of the equipment, but also poses a threat to the safety of operators. Moreover, ordinary fixed-bracket drilling equipment lacks flexible moving ability. Every time the operation position is changed, a large amount of time and manpower are required for disassembly, handling, and reinstallation and debugging, greatly reducing the construction efficiency and increasing the construction cost. With the continuous expansion of the project scale and the increasing diversification and complexity of the construction environment, it is extremely urgent to develop a drilling equipment that can operate stably, efficiently, and accurately under various terrain conditions. Summary of the Invention

[0004] In order to solve the above various problems, the present invention proposes a crawler single-arm drilling rig to solve the problems existing in the existing drilling equipment in terms of mobility, terrain adaptability, drilling accuracy, and working efficiency.

[0006] A crawler chassis, made of high-strength steel, the crawlers are made of a mixture of rubber and metal and are provided with anti-slip teeth, and the two side drive wheels are driven by independent drive motors through gearboxes;

[0007] A slewing platform, installed above the crawler chassis through a slewing bearing;

[0008] A single-arm drill arm, installed on one side of the slewing platform through a hinge seat, composed of multiple telescopic arms, the telescopic arms between each section are hydraulically driven to expand and contract, a drill tool connecting seat is provided at the front end, and an angle sensor is installed on the drill arm; the drill tool connecting seat includes a vertical metal frame and a drill pipe gripper;

[0009] A drill tool, including a connecting shaft and a drill pipe, the connecting shaft and the drill pipe are connected by a coupling, the connecting shaft is driven to rotate at high speed through a motor rotation drive device arranged in the vertical metal frame, and a hydraulic telescopic device is provided between the motor and the top of the vertical metal frame;

[0010] The power system uses a diesel engine or an electric motor as the power source and is installed inside the crawler chassis;

[0012] The auxiliary support device is installed on both sides of the crawler chassis.

[0013] Furthermore, the drill pipe gripper includes side plates welded to both sides under the vertical metal frame. A hydraulic push rod is connected through the side plates, and an arc-shaped clamping plate for clamping the rotating rod is connected to the extending end of the hydraulic push rod.

[0014] Furthermore, the slewing bearing is a crossed roller slewing bearing.

[0019] The advantages of the present invention compared with the prior art are as follows:

[0020] Excellent mobility: The crawler chassis is paired with an independent drive motor and transmission, enabling flexible adjustment of the traveling speed to meet the moving requirements under various complex working conditions. When transferring between different terrains, its moving stability is much higher than that of wheeled drilling equipment, eliminating the need for frequent adjustment of the equipment posture, greatly saving the moving time, and improving the operation flexibility.

[0021] Powerful terrain adaptability: The crawler made of a mixture of rubber and metal with anti-slip teeth, and the hydraulically adjustable outriggers enable the drilling rig to operate stably on complex terrains such as rugged mountain roads, muddy wetlands, and soft sandy lands. The auxiliary support device further enhances the support stability on complex terrains through the extending plates, hydraulic cylinders, and support floors connected to the four corners of the crawler chassis, expanding the equipment operation range.

[0022] High-precision drilling: The drill rod holder effectively prevents the drill rod from shaking or falling off through the coordinated action of the side plate, hydraulic push rod and arc clamping plate, ensuring the drilling accuracy. The angle sensor monitors the drill arm angle in real time, the displacement sensor accurately controls the drilling tool advancement depth, and the speed sensor adjusts the drilling tool speed according to different working conditions, fully ensuring that the drilling accuracy meets high standards.

[0023] High efficiency: The cross roller slewing bearing ensures the stable and precise rotation of the slewing platform, so that the single-arm drill arm can quickly align with different drilling positions and angles, reducing adjustment time. The telescopic arm with dovetail groove structure ensures smooth telescopic movement of the drill arm and stable structure. Combined with the efficient cooperation of the power system and control system, it greatly shortens the single drilling operation time, improves the overall construction progress, and reduces construction costs.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] Combined with Figure 1 To Attachment Figure 6 .

[0033] The side plates 12 welded to both sides below the vertical metal frame 6 serve as a stable installation foundation, ensuring the stability of the entire clamping structure. The hydraulic push rod 13 connected through the side plates 12 can accurately and flexibly adjust the extension length according to the diameter of different drill pipes 8 and the actual clamping requirements. The arc-shaped clamping plate 14 connected to the extended end of the hydraulic push rod 13 has an excellent fit with the surface of the drill pipe 8, greatly enhancing the stability and reliability of the clamping. When replacing the drill pipe 8, it can effectively prevent the drill pipe 8 from shaking or falling off, ensuring the accuracy and quality of the drilling, and providing a solid guarantee for efficient drilling operations.

[0034] The crossed roller slewing bearing 3 has the ability to withstand large axial forces, radial forces, and overturning moments. During the operation of the drilling rig, it can ensure that the slewing platform 2 maintains a high level of stability and accuracy during 360° full rotation. This enables the operator to adjust the drilling direction of the single-arm drill arm 4 more precisely and conveniently, greatly improving the adaptability of the drilling rig to different drilling positions and angles, and contributing to improving the construction efficiency and drilling quality.

[0035] The dovetail groove mating structure makes the telescopic movement of each telescopic arm smoother, effectively reducing the jamming phenomenon. At the same time, the dovetail groove structure greatly enhances the overall strength and rigidity of the drill arm. When adjusting the length of the drill arm according to different drilling depths and position requirements, it can ensure that the drill arm works stably and reliably, avoiding affecting the drilling accuracy due to structural instability, and providing strong support for the efficient and precise operation of the drilling rig.

[0036] Installing the displacement sensor 15 inside the vertical metal frame 6 and near the extended end of the hydraulic telescopic device 10 brings many benefits. The displacement sensor 15 can monitor the telescopic displacement of the hydraulic telescopic device 10 in real time and accurately. With this real-time data, the operator can precisely control the advancing depth of the drill tool. During the drilling operation, it can accurately adjust the advancing distance of the drill tool according to different geological conditions and drilling requirements, ensure that the drilling depth meets the design standards, and significantly improve the accuracy and construction quality of the drilling.

[0037] The rotational speed sensor 16 can monitor the rotational speed of the connecting shaft 7 in real time, and the connecting shaft 7 drives the drill pipe 8 to rotate for drilling operations. By obtaining the real-time rotational speed data feedback from the rotational speed sensor 16, the operator can timely and accurately adjust the rotational speed of the motor rotation drive device according to different rock hardnesses and drilling requirements, thereby optimizing the drilling efficiency and quality, and ensuring that the drilling rig can operate efficiently under various working conditions.

[0038] Connecting the extension plates 17 provided at the four corners of the crawler chassis 1 provides a stable installation position for the auxiliary support device. The hydraulic cylinders connected to the extension plates 17 can accurately adjust the extension length according to the flatness of the ground and the actual working conditions of the drilling rig. The support floor 18 connected to the extended end of the hydraulic cylinder increases the contact area with the ground. During the drilling operation, the support floor 18 contacts the ground, providing additional and stable support force for the drilling rig, effectively preventing the drilling rig from tilting or shaking during the drilling process, greatly improving the drilling accuracy and quality, and ensuring the stability and safety of the drilling rig operation.

[0039] Working principle: The operator starts the drive motor of the crawler chassis 1, adjusts the appropriate traveling speed through the gearbox, and moves the drilling rig to the designated working position. During the movement, the height of the hydraulic outriggers can be adjusted in a timely manner according to the terrain conditions to ensure the stability of the chassis. After reaching the working position, the operator controls the rotation of the slewing platform 2 through the control panel 11 in the cab, and adjusts the single-arm drill boom 4 to the required drilling direction. Then, operate the hydraulic cylinder to adjust the telescopic length and swing angle of the drill boom, so that the drill tool connecting seat is aligned with the drilling position. The angle sensor 5 monitors the angle change of the drill boom in real time and transmits the signal to the control system to ensure the accuracy of the drilling angle. Start the power system, and the hydraulic pump transmits the power to the motor rotation drive device and the hydraulic telescopic device 10 of the drill tool. The motor rotation drive device drives the connecting shaft 7 and the drill pipe 8 to rotate at high speed. At the same time, the hydraulic telescopic device 10 controls the propulsion speed and propulsion depth of the drill tool according to the preset program and the parameters collected by the sensors. During the drilling process, the displacement sensor 15 monitors the propulsion displacement of the drill tool in real time, and the rotational speed sensor 16 monitors the rotational speed of the drill pipe 8 in real time. The control system precisely controls the motor rotation drive device and the hydraulic telescopic device 10 according to these data to ensure the quality and efficiency of the drilling. The support floor 18 of the auxiliary support device extends during the drilling operation, contacts the ground, and provides additional support force for the drilling rig to prevent the drilling rig from tilting or shaking during the drilling process.

[0040] When the drilling reaches the predetermined depth, the hydraulic telescopic device 10 retracts the drill tool and stops the motor rotation drive device to stop the rotation of the drill pipe 8. When it is necessary to remove the drill pipe 8, the hydraulic push rod 13 extends, so that the arc-shaped clamping plate 14 clamps the drill pipe to prevent it from falling, and then the drill pipe 8 is removed. Then control the slewing platform 2 and the single-arm drill boom 4 to reset, retract the auxiliary support device and the hydraulic outriggers. Start the crawler chassis 1, move the drilling rig to the next drilling position, and repeat the above steps for the next drilling operation.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.

[0042] The above description of the present invention and its implementation manners is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
