Description

Technical Field

[0001] This invention relates to the field of mast drilling rig technology, and particularly to a mast drilling rig. Background Technology

[0002] A mast drilling rig, also known as a mast-type drilling rig, is a drilling device specifically designed for complex geological environments. It is widely used in surface drilling operations, especially in fields with complex geological conditions or high drilling accuracy requirements, such as exploration and infrastructure construction. Compared to traditional drilling rigs, mast drilling rigs offer greater stability and adaptability, enabling efficient operation under various surface conditions. Therefore, they are widely used in special environments requiring precise and efficient drilling.

[0003] In existing technologies, before drilling, the sand on the ground needs to be removed or leveled. Alternatively, after drilling, the movement of the drill bit may push sand from the hole to the vicinity of the borehole opening, requiring additional equipment to clear the target ground and ensure sufficient space around the opening. However, current mast drilling rigs typically require coordination with excavators, leading to frequent adjustments to the reference plane and axis of the drilling rig during operation. This iterative adjustment process significantly reduces operational efficiency and accuracy, thus affecting the stability of the drilling operation. Summary of the Invention

[0004] The main objective of this invention is to provide a mast drilling rig that makes the equipment more precise and stable in drilling operations, while improving the efficiency and accuracy of the entire operation process.

[0005] To achieve the above objectives, the present invention provides a mast drilling rig, comprising:

[0006] A frame, with a drive arm connected to the upper side of the frame, a flipping module connected to the drive arm, and a support plate hinged to the end of the drive arm away from the frame. The flipping module is used to adjust the angle between the drive arm and the support plate.

[0007] The drilling rig guide rail is rotatably connected to one side of the receiving plate, and a first motor is fixedly connected to the receiving plate. The drive shaft of the first motor is fixedly connected to the drilling rig guide rail.

[0008] A drill bit is slidably connected to a drilling rig guide rail, and a drive module is connected to the drilling rig guide rail. The drive module is used to drive the drill bit to rotate and drive the drill bit to reciprocate along the long side of the drilling rig guide rail.

[0009] A material shovel, which is connected to the lower end of the drill rig guide rail;

[0010] An adjustment component is disposed between the drill rig guide rail and the material shovel, and is used to adjust the material shovel according to different working modes.

[0011] In one possible implementation, the adjustment component includes:

[0012] A limiting frame is fixedly connected to one side near the lower end of the drilling rig guide rail, and a first limiting groove is provided on the limiting frame;

[0013] A limiting seat, on which a limiting block is fixedly connected, the minimum outer diameter of the limiting block being equal to the inner diameter of the first limiting groove, the limiting block abutting against the inner wall of the first limiting groove, and the material shovel being fixedly connected to the lower side of the limiting seat;

[0014] A positioning sleeve is connected to the drilling rig guide rail. A second motor is fixedly connected to the positioning sleeve. A transmission disc is rotatably connected to the positioning sleeve on the side facing the drilling rig guide rail. A transmission plate abuts against a non-center part of the transmission disc.

[0015] A linkage plate, which is hinged between the limiting seat and the transmission plate.

[0016] In one possible implementation, the transmission plate has a transmission groove, and the non-center part of the transmission disc abuts against the inner wall of the transmission groove.

[0017] In one possible implementation, a cylinder is fixedly connected to the drilling rig guide rail, the telescopic shaft of the cylinder is fixedly connected to the positioning sleeve, a second limiting groove is provided on one side of the first limiting groove, and the maximum outer diameter of the limiting block is equal to the inner diameter of the second limiting groove.

[0018] In one possible implementation, the material shovel is provided with multiple ribs.

[0019] In one possible implementation, the material shovel is provided with a material avoidance groove.

[0020] In one possible implementation, the lower side of the material shovel is a slope.

[0021] This invention's technical solution, through the cooperation of a flipping module and a first motor, enables precise adjustment of multiple degrees of freedom of the drill guide rail, keeping the drill bit's axis perpendicular to the horizontal plane. This improves the drilling effect and ensures the stability and accuracy of the drilling process. Furthermore, the adjustment components allow for flexible adjustment of the material shovel's working mode, achieving better coordination with the drill bit on the drill guide rail. During material shoveling, the shovel efficiently completes its task, smoothly removing material from the ground. When compacting the ground, it effectively prevents ground subsidence near the borehole, ensuring the stability of the hole during drilling. By flexibly adjusting the material shovel's working mode, the equipment's multifunctionality and ease of operation are further enhanced. Overall, these design improvements make the equipment more precise and stable in drilling operations, while improving the efficiency and accuracy of the entire operation, meeting the needs of different working modes, and greatly enhancing the equipment's adaptability and functionality.

[0031] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] This invention proposes a mast drilling rig.

[0034] Reference Figures 1 to 6 ,include:

[0035] A frame 11 is connected to a drive arm 12 on its upper side. A flipping module is connected to the drive arm 12. A support plate 13 is hinged to the end of the drive arm 12 away from the frame 11. The flipping module is used to adjust the angle between the drive arm 12 and the support plate 13.

[0036] The drilling rig guide rail 14 is rotatably connected to one side of the receiving plate 13. The first motor 15 is fixedly connected to the receiving plate 13, and the drive shaft of the first motor 15 is fixedly connected to the drilling rig guide rail 14.

[0037] Drill bit 16 is slidably connected to drill guide rail 14. A drive module is connected to drill guide rail 14. The drive module is used to drive drill bit 16 to rotate and drive drill bit 16 to reciprocate along the long side of drill guide rail 14.

[0038] Material shovel 17 is connected to the lower end of the drill guide rail 14;

[0039] An adjustment component is installed between the drill guide rail 14 and the material shovel 17 to adjust for different working modes of the material shovel 17;

[0040] By cooperating with the flipping module and the first motor 15, multiple degrees of freedom of the drill guide rail 14 can be precisely adjusted, keeping the axis of the drill bit 16 perpendicular to the horizontal plane, thereby improving the drilling effect of the drill bit 16 and ensuring the stability and accuracy of the drilling process. In addition, the adjustment component allows the working mode of the material shovel 17 to be flexibly adjusted, thereby achieving better cooperation with the drill bit 16 on the drill guide rail 14. During the material shoveling process, the material shovel 17 can efficiently complete the task, smoothly remove the material on the ground, and effectively prevent the ground near the hole from collapsing when compacting the ground, ensuring the stability of the hole when opening the hole. By flexibly adjusting the working mode of the material shovel 17, the multi-functionality and ease of operation of the equipment are further improved. Overall, these design improvements make the equipment more accurate and stable in drilling operations, while improving the efficiency and accuracy of the entire operation process, meeting the needs of different working modes, and greatly enhancing the adaptability and functionality of the equipment.

[0041] Reference Figures 1 to 6 The adjustment components include:

[0042] The limiting frame 21 is fixedly connected to one side near the lower end of the drilling rig guide rail 14, and the limiting frame 21 is provided with a first limiting groove 221.

[0043] A limiting seat 23 is fixedly connected to a limiting block 24. The minimum outer diameter of the limiting block 24 is equal to the inner diameter of the first limiting groove 22. The limiting block 24 abuts against the inner wall of the first limiting groove 22. The material shovel 17 is fixedly connected to the lower side of the limiting seat 23.

[0044] Positioning sleeve 25 is connected to the drilling rig guide rail 14. A second motor 26 is fixedly connected to the positioning sleeve 25. A transmission plate 27 is rotatably connected to the side of the positioning sleeve 25 facing the drilling rig guide rail 14. A transmission plate 28 abuts against the non-center part of the transmission plate 27.

[0045] Linkage plate 29 is hinged between limit seat 23 and transmission plate 28;

[0046] By adjusting the components, the working mode of the material shovel 17 can be flexibly adjusted, so that it can better cooperate with the drill bit 16 on the drill guide rail 14. During the shoveling process, the material shovel 17 can complete the work efficiently, which can not only remove the material on the ground smoothly, but also ensure that the part of the hole close to the ground is not easy to collapse when drilling by compacting the ground, thereby ensuring the stability and reliability of the hole opening effect. This makes the adjustment of the material shovel 17 more flexible in different working modes, greatly enhancing the multifunctionality and ease of operation of the equipment, and improving the efficiency and accuracy of the entire operation process.

[0047] Reference Figure 5The transmission plate 28 has a transmission groove 281, and the non-center part of the transmission disc 27 abuts against the inner wall of the transmission groove 281.

[0048] The non-center part of the transmission disc 27 abuts against the inner wall of the transmission groove 281. This design allows the rotation of the transmission disc 27 to drive the transmission plate 28 up and down, thereby adjusting the working mode of the material shovel 17. Users can flexibly adjust the working mode of the material shovel 17 according to the rotation angle and speed of the transmission disc 27. When the user needs the material shovel 17 to perform a shoveling task, the rotation angle of the transmission disc 27 can be adjusted, making it easier for the material shovel 17 to remove materials from the processing ground, allowing it to complete the work efficiently during shoveling. On the other hand, when the user needs to compact the ground near the drill hole, the transmission disc 27 can be quickly rotated to drive the material shovel 17 to compact the ground. During drilling, the part of the hole near the ground is less likely to collapse, ensuring the stability and reliability of the drilling effect. This makes the adjustment of the material shovel 17 more flexible in different working modes, further improving the multifunctionality and ease of operation of the equipment.

[0049] Reference Figures 2 to 5 A cylinder 31 is fixedly connected to the drilling rig guide rail 14. The telescopic shaft of the cylinder 31 is fixedly connected to the positioning sleeve 25. A second limiting groove 222 is opened on one side of the first limiting groove 221. The maximum outer diameter of the limiting block 24 is equal to the inner diameter of the second limiting groove 222.

[0050] The positioning sleeve 25 is driven by cylinder 311 to move along the long side of the drilling rig guide rail 14. When the positioning sleeve 25 moves upward, the limiting block 24 will drive the limiting seat 23 from the first limiting groove 221 to the second limiting groove 222. At this time, the rotation of the transmission disc 27 will drive the material shovel 17 to move upward as a whole. During this process, since the maximum outer diameter of the limiting block 24 is equal to the inner diameter of the second limiting groove 222, the weight of the material shovel 17 itself will cause its center of gravity to shift. As a result, the material shovel 17 will flip during the upward movement. The flipping design of the material shovel 17 allows it to be retracted when moving upward. After the drilling operation is completed, the user can more easily observe the inside of the hole, reducing the obstruction to hole observation and improving the user's operational convenience and observation efficiency after the operation. In addition, this flipping mechanism also optimizes the storage and operation of the equipment, ensuring the smoothness and efficiency of the operation process.

[0051] Reference Figures 4 to 6 The material shovel 17 has multiple ribs 171 inside;

[0052] The design of ribs 171 significantly enhances the strength of the material shovel 17, effectively improving its load-bearing capacity and reducing deformation or damage under high-intensity operations. In addition, the ribs 171 can also distribute the pressure applied to the material shovel 17 during operation, reduce the wear rate, and further extend the service life of the material shovel 17. This not only improves the durability of the material shovel 17 but also enhances its adaptability in complex environments, ensuring more efficient operation for a longer period of time.

[0053] Reference Figures 4 to 6 The material shovel 17 is provided with a material avoidance groove 172;

[0054] With the material avoidance groove 172, when the drill bit 16 drills downward along the drill guide rail 14, the material shovel 17 does not need to be flipped upward, thereby reducing unnecessary operation procedures and significantly improving processing efficiency. At the same time, it makes the cooperation between the material shovel 17 and the drill bit 16 more precise, effectively ensuring the stability of the drill bit 16 during the drilling process. Before and after drilling, the material shovel 17 can better scoop material from the construction ground, optimizing the working environment and material handling, improving overall work efficiency, simplifying operation steps, enhancing the collaborative operation capability of the equipment, and improving the smoothness and accuracy of the construction process. In addition, with the material avoidance groove 172, the sand falling on the material shovel 17 can fall more effectively through the material avoidance groove 172, ensuring the scooping effect of the material shovel 17.

[0055] Reference Figures 2 to 6 The lower side of the material shovel 17 is a slope 173;

[0056] The lower side of the material shovel 17 is designed as a slope 173. The purpose is to effectively reduce the contact area between the bottom of the material shovel 17 and the working ground when the user has adjusted the verticality of the drilling rig guide rail 14 through the frame 11 and then uses the material shovel 17 to perform soil or material shoveling operations. This reduces wear and extends the service life of the material shovel 17. It also makes the material shovel 17 operate more smoothly and improves work efficiency. It can improve the smoothness of soil or material shoveling operations, reduce frequent maintenance and replacement due to excessive wear, and improve the overall stability and economy of operation.
