Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, specifically to a fully hydraulic portable drilling rig in-situ adjustment device. Background Technology

[0002] Portable drilling rigs, due to their compact structure and maneuverability, can be transported in mountainous areas using pallet trucks, significantly improving transport efficiency and adaptability compared to traditional vertical shaft drilling rigs. However, in actual construction, especially during inclined hole operations, it is often necessary to adjust the rig's head orientation according to geological design requirements. Existing operating methods typically rely on manual labor or auxiliary equipment to move and turn the entire machine, which is not only inefficient but also places high demands on the construction site.

[0003] In some geographically limited and terrain-complex operating areas, drilling rigs cannot be directionally adjusted using conventional methods. Forcibly expanding the construction platform would not only increase the land area occupied but also potentially damage surface vegetation, violating the basic principles of green exploration and ecological protection.

[0004] Therefore, there is an urgent need for an auxiliary device that can accurately adjust the orientation of the drilling rig without moving it or expanding its footprint, so as to improve construction efficiency and reduce environmental disturbance. Summary of the Invention

[0005] To address the problems in the background art, the present invention provides a fully hydraulic portable drilling rig in-situ adjustment device to solve the problems of existing portable drilling rigs being limited by terrain, occupying a large area, and being difficult to operate when adjusting their orientation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fully hydraulic portable drilling rig in-situ adjustment device includes a support base, a movable component at the bottom of the support base including four sets of movable wheels, and a support platform at the top of the support base. Movable frames are provided around the center of each perimeter of the support platform, and the movable frames are connected to the support platform via two sets of first electric push rods. A lifting component and a rotating component are provided at the bottom of the support platform. The lifting component includes four sets of hydraulic rods used to drive the support platform to move up and down, and the rotating component is used to drive the support platform to rotate. An auxiliary support assembly includes four sets of support plates, which are respectively installed on the four sides of the support base. The bottom of each support plate is movably connected to the support base. A second electric push rod is movably connected to the upper surface of each support plate. The second electric push rod is used to drive the support plate to rotate 90 degrees.

[0007] Preferably, a lifting platform is provided at the upper center of the support base, and the rotating assembly is installed at the upper center of the lifting platform. The rotating assembly includes a rotating body, which is movably mounted on the upper surface of the lifting platform via a bearing.

The external gear ring is fixedly installed on the outer wall of the rotating body. The drive motor is fixedly installed on the upper left side of the lifting platform. The drive gear is fixedly installed on the output shaft of the drive motor and meshes with the external gear ring.

[0009] Preferably, a lifting column is provided at the bottom center of the lifting platform. The lifting column is slidably installed in the middle of the inner cavity of the support seat. Four sets of hydraulic rods surround the lifting column and are respectively installed at the four sides of the bottom of the lifting platform. The bases of the four sets of hydraulic rods are all fixedly installed in the inner cavity of the support seat.

[0010] Preferably, the four side walls of the support base are provided with storage slots in the middle, the storage slots are used to store the support plate, and the bottom of the support plate is movably installed on the lower side of the inner cavity of the storage slot via a pivot.

[0011] Preferably, the base of the second electric push rod is movably installed in the corresponding storage slot, and its output end is movably connected to the upper surface of the support plate.

[0013] Preferably, the bottom of the support base is provided with a storage compartment, the lifting frame is movably installed in the middle of the inner side of the storage compartment, and a third electric push rod is provided at each of the four corners of the upper end of the lifting frame. The third electric push rod is fixedly installed in the inner cavity of the support base. The four sets of third electric push rods are synchronously driven by a controller to drive the lifting frame to move up and down in the storage compartment.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a support platform, lifting components, and rotating components, can lift and rotate the entire drilling rig smoothly without moving the rig body or expanding the construction area.

[0017] The technical solution in this application embodiment addresses the problems described in the background. The overall concept is as follows: This invention primarily utilizes a rotating component and a lifting component to smoothly rotate the drilling rig after lifting it as a whole. Precise adjustment of the azimuth angle can be achieved without moving the rig body, making it particularly suitable for construction environments with limited geographical space. Furthermore, by employing a combination of full hydraulic drive and electric push rods to replace traditional manual adjustment, labor intensity is significantly reduced, and the risk of equipment tipping or personnel injury during manual prying is avoided, thereby effectively improving operational safety and convenience. In addition, the device of the present invention is movable as a whole, and only needs to be supported briefly at the bottom of the drilling rig during operation. There is no need to open up an additional working platform, which effectively controls the construction area, meets the environmental protection requirements of green exploration, and reduces ecological damage.

[0018] Furthermore, by providing a retractable auxiliary support component at the bottom of the device, the support plate 14 can be extended outward during jacking operations, significantly increasing the support area and preventing the device from overturning due to a shift in the center of gravity. The structure is stable and highly adaptable. At the same time, it is equipped with liftable casters 17, which facilitates the quick movement of the entire device into and out of the bottom of the drilling rig. It is flexible in use and reusable.

[0019] Example: Refer to Figure 1 - Figure 6 As shown in the figure, a fully hydraulic portable drilling rig in-situ adjustment device of this embodiment includes a support base 1, a support platform 2 above the support base 1 for directly supporting the drilling rig body, and a movable frame 3 in the center of each of the four sides of the support platform 2. Each movable frame 3 is connected to the support platform 2 by two sets of first electric push rods 4. By pushing the movable frame 3 outward by the first electric push rods 4, the contact area with the bottom of the drilling rig can be increased, thereby enhancing the load-bearing capacity and improving the stability of the drilling rig lifting.

[0020] In some examples, the bottom of the support platform 2 is connected to both a lifting assembly and a rotating assembly: the lifting assembly includes four sets of hydraulic rods 7, which can provide a smooth and powerful lifting action to raise the support platform 2 together with the drilling rig on it; the rotating assembly is used to drive the support platform 2 to rotate in the horizontal direction, thereby adjusting the orientation angle of the drilling rig.

[0021] The support base 1 has a lifting platform 5 at the upper center. The lifting platform 5 serves as the mounting base for the rotating assembly. The rotating body 8 in the rotating assembly is mounted on the upper surface of the lifting platform 5 through bearings. This bearing connection method enables the rotating body 8 to withstand large axial loads and overturning moments, while ensuring that its rotation in the horizontal direction is flexible and stable. The support platform 2 is fixedly installed above the rotating body 8. Therefore, when the rotating body 8 rotates, the support platform 2 and the drilling rig it supports rotate synchronously to achieve orientation adjustment.

[0022] In addition, a drive assembly is provided at the left end of the rotating body 8. The drive assembly includes an external gear ring 9, a drive gear 10, and a drive motor 11. The external gear ring 9 is fixedly installed on the outer wall of the rotating body 8, and the drive motor 11 is fixedly installed on the upper left side of the lifting platform 5. The drive gear 10 is fixedly installed on the output shaft of the drive motor 11 and meshes with the external gear ring 9. When the drive motor 11 starts, the drive gear 10 drives the external gear ring 9 to rotate, thereby causing the rotating body 8 to rotate around its axis. This drive method has a compact structure, smooth transmission, and can achieve stepless speed regulation and precise angle control, making it convenient for operators to accurately adjust the azimuth angle of the drilling rig according to construction requirements.

[0023] In some examples, to ensure the guidance and stability of the lifting process, a lifting column 6 is provided at the bottom center of the lifting platform 5. The lifting column 6 extends downward into the inner cavity of the support seat 1 and forms a sliding fit with the support seat 1, playing a central guiding role. Four sets of hydraulic rods 7 are evenly arranged around the periphery of the lifting column 6, and their top ends are fixedly connected to the four positions of the bottom of the lifting platform 5. The bottom base is fixed to the bottom of the inner cavity of the support seat 1. Through the synchronous extension and retraction of the four sets of hydraulic rods 7, the lifting platform 5 is pushed to rise and fall smoothly along the axial direction of the lifting column 6, thereby driving the support platform 2 and the drilling rig as a whole to rise or fall.

[0024] In some examples, to further improve the overall stability during lifting operations, the device is also equipped with auxiliary support components, including four sets of support plates 14, arranged in the front, rear, left, and right directions of the support base 1. The bottom of each support plate 14 is movably connected to the support base 1, and the upper part is connected to the support base 1 via a second electric push rod 13. When the second electric push rod 13 extends or retracts, it can drive the support plate 14 to rotate 90 degrees outward around its bottom axis, changing the support plate 14 from a retracted state to a horizontally extended state. This significantly increases the contact area between the device and the ground, preventing the risk of overturning due to changes in the center of gravity during lifting and rotation.

[0025] In addition, to make the device compact, easy to move and store when not in operation, a storage slot 12 is provided in the middle of each of the four sides of the support base 1. The shape of the storage slot 12 matches the support plate 14. When the auxiliary support assembly is not in use, the support plate 14 is completely stored in the storage slot 12. Its outer surface is basically flush with the outer wall of the support base 1 to avoid the protruding part from bumping or obstructing during movement. The bottom of the support plate 14 is installed on the lower side of the inner cavity of the storage slot 12 through a pivot, so that the support plate 14 can be rotated outward or retracted inward around the pivot.

[0026] The base of the second electric push rod 13 is hinged at one end and installed at a suitable position on the inner side wall of the storage slot 12. The end of its telescopic rod is movably connected to the upper end face of the support plate 14. When the telescopic rod of the second electric push rod 13 extends outward, it pushes the support plate 14 to rotate outward around its bottom axis until the support plate 14 reaches a horizontally unfolded state, achieving a 90-degree rotation. When it needs to be retracted, the telescopic rod retracts, pulling the support plate 14 back into the storage slot 12. This structure realizes the automatic unfolding and storage of the support plate 14, which is simple and reliable to operate.

[0027] In some examples, the bottom of the support base 1 is equipped with a movable component, including four sets of movable wheels 17, which facilitates the flexible movement of the entire device on the construction site and enables it to be quickly moved to the bottom of the drilling rig for standby.

[0028] The mobile component also includes a lifting frame 16, with four sets of moving wheels 17 fixedly installed at the four bottom corners of the lifting frame 16. The lifting frame 16 is used to integrate all the moving wheels 17, ensuring that the four sets of moving wheels 17 can rise and fall synchronously, thereby ensuring that the device remains horizontal when switching between moving and supporting states, and avoiding tilting of the device due to the suspension or sinking of one side of the wheel set.

[0029] Additionally, a storage compartment 15 is provided at the bottom of the support base 1, and a lifting frame 16 is installed inside the storage compartment 15. Four sets of third electric push rods 18 are connected to the four corners of the upper end of the lifting frame 16. The top of the third electric push rods 18 is fixed to the internal structure of the support base 1. The four sets of third electric push rods 18 are synchronously driven by the same controller to ensure that they extend and retract at the same time and have the same stroke.

[0030] When the device needs to be moved, the four sets of third electric push rods 18 extend synchronously, pushing the lifting frame 16 downward so that the moving wheels 17 contact the ground and lift the support base 1 as a whole. At this time, the device can be pushed freely. When the device reaches the working position and needs to be lifted, the third electric push rods 18 retract synchronously, putting the lifting frame 16 together with the moving wheels 17 into the storage compartment 15, so that the bottom of the support base 1 falls directly to the ground or is supported by the unfolded support plate 14, ensuring that the device is stable and does not slip during operation.

[0031] The working principle of this invention is: Before adjusting the drilling rig's orientation, in the initial state, the third electric push rod 18 extends, pushing the lifting frame 16 to drive the four sets of moving wheels 17 to extend downwards from the storage compartment 15, lifting the support base 1 off the ground. At this time, the operator can push the device directly below the portable drilling rig, aligning the support platform 2 with the appropriate load-bearing position at the bottom of the drilling rig.

[0032] Upon reaching the predetermined position, the third electric push rod 18 retracts simultaneously, causing the lifting frame 16 and the moving wheels 17 to rise, thus retracting the moving wheels 17 into the storage compartment 15. At this point, the bottom surface of the support base 1 rests smoothly on the ground. Subsequently, the second electric push rod 13 is activated, pushing the four sets of support plates 14 outward, causing them to unfold 90 degrees outward from the storage slots 12 in four directions, so that they are in a horizontal position against the ground. This significantly increases the contact area between the device and the ground, preventing overturning during subsequent lifting and rotation.

[0033] Then, the first electric push rod 4 is activated, pushing the movable frame 3 to move outward, thereby increasing the support area of ​​the support platform 2 and preventing the drilling rig from shaking or shifting during lifting and rotation.

[0034] After some preparations are completed, the drilling rig can be lifted. First, the four sets of hydraulic rods 7 extend synchronously, pushing the lifting platform 5 and the lifting column 6 to rise steadily, which in turn drives the support platform 2 to move upward until the support platform 2 contacts the bottom of the drilling rig and lifts it completely, so that all the moving wheels 17 of the drilling rig are off the ground.

[0035] Then, the drive motor 11 starts, driving the outer gear ring 9 and the rotating body 8 to rotate via the drive gear 10. The support platform 2 rotates smoothly accordingly, and the drilling rig as a whole achieves in-situ adjustment of the azimuth angle while in a lifting state. The operator controls the rotation angle according to the construction requirements, and the motor stops when the desired position is reached.

[0036] Reset and withdrawal phase: After adjustment, multiple sets of hydraulic rods 7 retract synchronously, driving the lifting platform 5 and support platform 2 to descend, so that the drilling rig falls back to the ground. Then, the movable frame 3 retracts, and the second electric push rod 13 retracts the support plate 14, so that it returns to the storage slot 12. Finally, the third electric push rod 18 extends, and the moving wheel 17 lifts the support base 1 again. The operator then removes the device from the bottom of the drilling rig for future use.
