Description

Technical Field

[0001] This utility model relates to the field of exploration equipment technology. Specifically, it is a positioning frame for boreholes in rock and soil exploration. Background Technology

[0002] Exploratory boreholes are drilled to obtain physical parameters of underground soil and rock layers, providing in-situ data support for drilling projects. Exploratory boreholes are drilled downwards from the ground using exploration drilling rigs. Exploratory drilling rigs can be categorized by size: micro-rigs, small rigs, medium rigs, and large rigs. Medium and large rigs are larger and heavier, typically possessing complete walking mechanisms, drill bit adjustment structures, and support structures, resulting in higher stability. The drill bit adjustment structure allows for adjustments to the borehole direction and position. Micro and small drilling rigs are usually transported by vehicles and then manually moved to the required location, secured by manpower or simple support frames before drilling. This method of securing is directly affected by various factors such as ground slope, the strength and angle of manual support, making it difficult to ensure the drill bit drills at a predetermined angle. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a positioning support for a micro drilling rig, so that the drill bit can drill at a preset angle and maximize the accuracy of the drilling path.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drilling positioning frame for rock and soil exploration, comprising a base, a hinge frame, a guide support frame, and a sliding table. The first end of the hinge frame is hinged to the first end of the base via a hinge. The sliding table is slidably fitted within the guide support frame. Arc-shaped sliding plates are fixedly installed on the top two sides of the guide support frame. Arc-shaped connecting seats are rotatably installed on the opposite side walls of the hinge frame via a first rotating shaft at the second end of the hinge frame. The guide support frame is located within the hinge frame, and... The arc-shaped sliding plates on both sides of the guide support frame are slidably engaged in the two arc-shaped connecting seats respectively; the guide support frame can swing freely relative to the hinge frame through the cooperation of the first rotating shaft, the arc-shaped connecting seats and the arc-shaped sliding plates; a first limiting component is installed on the top of the guide support frame, the end of the first limiting component is connected to the arc-shaped connecting seat and restricts the swing of the guide support frame relative to the arc-shaped connecting seat; a second limiting component is installed on the hinge frame, the end of the second limiting component is connected to the first rotating shaft and restricts the rotation of the first rotating shaft.

[0005] The aforementioned drilling positioning frame for rock and soil exploration includes a hinged frame that swings upward along the base via a hinge to extend and lift the guide support frame. The guide support frame is vertically downward under the action of gravity, and its bottom is supported on the ground. The base, the hinged frame, and the guide support frame form a triangular structure.

[0006] The aforementioned positioning frame for drilling holes in rock and soil exploration has a support rod rotatably connected to the side wall of the base via a hinge shaft. The other end of the support rod is detachably connected to the side wall of the hinge frame via bolts. Fixing holes are distributed along the length of the side wall of the support rod.

[0007] The aforementioned positioning frame for drilling holes in rock and soil exploration has a first limiting component fixedly installed on both sides of the top of the guide support frame. The first limiting component includes a fixing plate and a first screw. The fixing plate is fixedly installed on the top of the guide support frame and located directly above the arc-shaped connecting seat. The fixing plate has a threaded hole, and the first screw is threaded into the threaded hole on the fixing plate. The end of the first screw abuts against the top of the arc-shaped connecting seat.

[0008] In the aforementioned positioning frame for drilling holes in rock and soil exploration, the first rotating shaft passes through the hinge frame and is rotatably connected to the hinge frame. The first end of the first rotating shaft is fixedly connected to the arc-shaped connecting seat, and the other end of the first rotating shaft is connected to the second limiting component.

[0009] The aforementioned positioning frame for drilling holes in rock and soil exploration includes a second limiting component comprising a connecting platform, a second screw, a connecting frame, and a swing arm. One end of the swing arm is fixedly connected to the second end of the first rotating shaft. The connecting platform is rotatably mounted on the side wall of the hinge frame. A threaded hole is formed through the connecting platform along its diameter. The second screw is threaded into the threaded hole on the connecting platform. The connecting frame is fixedly mounted on the end of the second screw. Pin holes are formed on the side wall of the connecting frame and the free end of the swing arm. The connecting frame and the swing arm are connected by pins.

[0010] The aforementioned positioning frame for boreholes in geotechnical exploration includes a guide support frame comprising a fixed frame and two sets of symmetrically arranged linear guide rods. The fixed frame is fixedly installed on both ends of each linear guide rod. A sliding table is installed between the two sets of linear guide rods, and the two sides of the sliding table slide in cooperation with the linear guide rods via sliders. An arc-shaped sliding plate is installed on the outer wall surface of the linear guide rods.

[0011] In the aforementioned positioning frame for drilling holes in rock and soil exploration, the outer diameters of the arc-shaped sliding plates on both sides of the guide support frame are the same, and the center points of the two arc-shaped sliding plates coincide; the inner diameter of the arc-shaped connecting seat matches the outer diameter of the arc-shaped sliding plate.

[0012] The aforementioned positioning frame for drilling holes in rock and soil exploration has adjustable support feet threadedly connected to the four corners of the bottom end of the guide support frame.

[0013] The aforementioned drilling positioning frame for rock and soil exploration has an operating platform plate at the second end of the base for personnel to stand on.

[0014] The technical solution of this utility model has achieved the following beneficial technical effects:

[0015] 1. By setting a base and hinge frame that form a triangular structure, a stable support effect can be provided for the guide support frame. Since the guide support frame can swing in any direction relative to the hinge frame, under the action of gravity, the guide support frame can automatically move vertically downward and lock the angle with the first limit component and the second limit component. When the drill bit drills, it can drill vertically and achieve the effect of positioning support.

[0016] 2. By setting up support rods, the force borne by the hinge frame is transferred to the base, ensuring the stability of the guide support frame during drilling. Conventional micro-drills generally require a person to stand and support them, which requires a lot of physical strength, especially when the drill is positioned high or low, where it is difficult to exert force. Not only must the vertical direction be controlled, but the horizontal angle must also be controlled, making the drill more prone to tilting. At this time, the positioning effect of the drill is further reduced. In this application, the sliding table can only slide up and down within the guide support frame, requiring only slight support from the operator. When the guide support frame is subjected to tilting force, it is transferred to the base through the hinge frame and support rods. The hinge frame, support rods, and base form a stable triangle. The connection between the base and the support rod and the operating platform plate effectively lengthens the lever arm. When a person stands on the operating platform plate, their own weight presses down on the base, improving the stability of the entire support and significantly reducing labor intensity.

[0017] 3. By setting four adjustable support feet, the bottom of the guide support frame can be stably supported on the uneven ground, and both ends of the guide support frame are effectively supported.

[0018] 4. In this application, the various components are connected by hinges, which can be quickly folded when not in use, greatly reducing the volume and facilitating transportation. During assembly, they can also be quickly supported and put into use. Attached Figure Description

Detailed Implementation

[0024] The geotechnical exploration borehole positioning frame in this embodiment, such as Figure 1 As shown, the system includes a base 1, a hinge frame 2, a guide support frame 6, and a sliding table 7. The first end of the hinge frame 2 is hinged to the first end of the base 1. The second end of the base 1 is provided with an operating platform 10 for personnel to stand on. The sliding table 7 is slidably fitted within the guide support frame 6. Arc-shaped sliding plates 5 are fixedly installed on the top of both sides of the guide support frame 6. Arc-shaped connecting seats 4 are rotatably installed on the opposite side walls of the hinge frame 2 via a first rotating shaft 12 at the second end of the hinge frame 2. The guide support frame 6 is located within the hinge frame 2, and the arc-shaped sliding plates 5 on both sides of the guide support frame 6... The guide support frame 6 is slidably fitted into two arc-shaped connecting seats 4. The outer diameters of the arc-shaped sliding plates 5 on both sides of the guide support frame 6 are the same, and the center points of the two arc-shaped sliding plates 5 coincide. The inner diameter of the arc-shaped connecting seat 4 matches the outer diameter of the arc-shaped sliding plate 5, meaning that the arc-shaped sliding plate 5 can swing freely within the arc-shaped connecting seat 4. By setting up a base 1 and a hinge frame 2 that form a triangular structure, a stable support effect can be provided for the guide support frame 6. Since the guide support frame 6 can swing relative to the hinge frame 2 in any direction, under the action of gravity, the guide support frame 6 can automatically move vertically downward, meeting the requirements of vertical drilling.

[0025] like Figure 1 , Figure 3 As shown, the hinge frame 2 swings upward along the base 1 via a hinge to unfold and lift the guide support frame 6. The guide support frame 6 is vertically downward under the action of gravity, and the bottom of the guide support frame 6 is supported on the ground. The base 1, the hinge frame 2 and the guide support frame 6 form a triangular structure. A support rod 3 is rotatably connected to the side wall of the base 1 via a hinge shaft. The other end of the support rod 3 is detachably connected to the side wall of the hinge frame 2 by bolts. Fixing holes are distributed along the length of the side wall of the support rod 3.

[0026] like Figure 1-2As shown, the guide support frame 6 can swing freely relative to the hinge frame 2 through the cooperation of the first rotating shaft 12, the arc-shaped connecting seat 4 and the arc-shaped sliding plate 5; a first limiting component 8 is installed on the top of the guide support frame 6, the end of the first limiting component 8 is connected to the arc-shaped connecting seat 4 and restricts the swing of the guide support frame 6 relative to the arc-shaped connecting seat 4; a second limiting component 9 is installed on the hinge frame 2, the end of the second limiting component 9 is connected to the first rotating shaft 12 and restricts the rotation of the first rotating shaft 12.

[0027] Specifically, such as Figure 2 As shown, first limiting components 8 are fixedly installed on both sides of the top of the guide support frame 6. The first limiting component 8 includes a fixing plate 81 and a first screw 82. The fixing plate 81 is fixedly installed on the top of the guide support frame 6 and located directly above the arc-shaped connecting seat 4. The fixing plate 81 has a threaded hole. The first screw 82 is threaded into the threaded hole on the fixing plate 81. The end of the first screw 82 abuts against the top of the arc-shaped connecting seat 4.

[0028] like Figure 3 As shown, the first rotating shaft 12 passes through the hinge frame 2 and is rotatably connected to the hinge frame 2. The first end of the first rotating shaft 12 is fixedly connected to the arc-shaped connecting seat 4, and the other end of the first rotating shaft 12 is connected to the second limiting component 9. The second limiting component 9 includes a connecting platform 91, a second screw 92, a connecting frame 93, and a swing arm 94. One end of the swing arm 94 is fixedly connected to the second end of the first rotating shaft 12. The connecting platform 91 is rotatably mounted on the side wall of the hinge frame 2. A threaded hole is opened through the connecting platform 91 along its diameter direction. The second screw 92 is threaded into the threaded hole on the connecting platform 91. The connecting frame 93 is fixedly mounted on the end of the second screw 92. Pin holes are opened on the side wall of the connecting frame 93 and the free end of the swing arm 94. The connecting frame 93 and the swing arm 94 are connected by pins. The first limiting component 8 and the second limiting component 9 lock the angle, allowing the drill bit to drill vertically and achieve the effect of positioning and support. Furthermore, based on the vertical downward position of the guide support frame 6, the first limiting component 8 and the second limiting component 9 can also slightly adjust the angle of the guide support frame 6 to achieve angled drilling.

[0029] like Figure 1 As shown, the guide support frame 6 includes a fixed frame 61 and two sets of symmetrically arranged linear guide rods 62. The fixed frame 61 is fixedly installed on both ends of the linear guide rods 62. The sliding table 7 is installed between the two sets of linear guide rods 62, and the two sides of the sliding table 7 are slidably engaged with the linear guide rods 62 through sliders. The arc-shaped sliding plate 5 is installed on the outer wall of the linear guide rods 62. Adjustable support feet 11 are threadedly connected to the four corners of the bottom end of the guide support frame 6.

[0030] Specific working principle: such as Figure 4As shown, the drilling positioning frame for geotechnical exploration is small in size when folded, making it easy to transport. After transporting the support frame to the specific location, the ground at the predetermined location is cleared, and the base 1 is placed on the ground. Due to the slope of the ground, the base 1 cannot be perfectly horizontal. Then, the hinge frame 2 is lifted upwards, and the hinge frame 2 rotates along the hinge position. At the same time, the guide support frame 6 is lifted. When the support frame 6 is just completely off the ground, the support rod 3 is rotated and connected to the hinge frame 2, so that the base 1, hinge frame 2, and support rod 3 form a support. At this time, the guide support frame 6 swings freely under the action of gravity and then comes to a vertically downward position. At this point, the first limiting component 8 and the second limiting component 9 are not in a limiting state. Then, the first screw 82 at the top of the guide support frame 6 is turned until both first screws 82 are pressed against the arc-shaped connecting seat 4, restricting the left and right swing of the guide support frame 6. Then, the second screw 92 is turned to adjust the extension length of the connecting frame 93 until the connecting frame 93 and the swing arm 94 can be connected. The connecting frame 93 and the swing arm 94 are then connected together by a pin, restricting the rotation of the first rotating shaft 12, that is, restricting the back and forth swing of the guide support frame 6. Then, the four adjustable support feet 11 are adjusted to contact the ground to form a support.

[0031] Handles 13 connected by threads can be installed at the front and rear of the sliding table 7. When a person stands on the operating platform plate 10, the person can press down the positioning frame. A drilling machine is installed on the sliding table 7, and drill rods, drill bits, etc. are installed on the output shaft of the drilling machine. By pushing the sliding table 7 downward, drilling can be performed.

[0032] The guide support frame 6 swings under the action of gravity in two ways: forward and backward swinging and left and right swinging. The forward and backward swinging is achieved by the first rotating shaft 12, and the left and right swinging is achieved by the arc-shaped sliding plate 5 sliding in the arc-shaped connecting seat 4.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
