Description

Technical Field

[0001] This invention relates to a drilling rig, specifically a multi-functional rock and soil geological drilling rig, belonging to the field of geological drilling technology. Background Technology

[0002] Rock and soil geological drilling, as a core technology for obtaining underground rock and soil samples and geological information, is widely used in key areas such as engineering surveys, mineral resource exploration, and geological disaster early warning. The data obtained directly provides a scientific basis for foundation design, resource development planning, and disaster prevention and control schemes. Rock and soil geological drilling rigs, as the core carrier of this technology, need to integrate functions such as rotary drilling, power output, and depth control. Depending on the characteristics of different strata, such as soft soil, sand layers, and hard rock, they can flexibly adopt rotary, impact, or combined drilling modes, and be combined with a cuttings removal system, such as mud circulation and air cuttings removal, to achieve efficient drilling. Their performance directly determines the drilling depth, core quality, and operational efficiency, making them an indispensable "underground detection terminal" in the field of geological exploration.

[0003] Current mainstream rock and soil geological drilling rigs have significant limitations in their operation modes, making them difficult to adapt to complex and ever-changing field operating environments: Support-assisted drilling rigs rely on fixed or adjustable supports to operate. Although they can ensure the stability and accuracy of the drilling process through mechanical structure, and are especially suitable for deep drilling or hard rock formations, the installation and debugging of the supports require a lot of time. In addition, the overall equipment is large and heavy, making it difficult to move and deploy flexibly in narrow spaces, such as tunnels, the edge of foundation pits, or in rugged terrain such as mountains and steep slopes. This greatly limits its application scenarios in complex terrain.

[0004] Handheld drilling rigs: With their advantages of being lightweight and flexible, they can quickly adapt to narrow spaces or temporary work needs. However, their drilling stability depends entirely on the operator's hand control, and the drilling angle is easily deviated due to human error, affecting the core sampling accuracy. At the same time, the power output is limited in handheld mode, making it difficult to deal with hard formations. Furthermore, prolonged operation can easily cause operator fatigue and pose safety hazards.

[0005] The divergence between these two operating modes makes it difficult for existing drilling rigs to balance operational efficiency, drilling accuracy, and environmental adaptability when facing complex terrain and spatially varied field geological exploration tasks. Therefore, developing a multi-functional rock and soil geological drilling rig that can flexibly switch operating modes and balance stability and portability has become a key requirement for overcoming current technological bottlenecks.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 As shown, a multi-functional rock and soil geological drilling rig includes an electric control frame 1 and a handheld drilling machine 2. The electric control frame 1 includes: The electric base 101 contains a drive battery, a drive unit, a drive wheel, and control components. The control components are connected to the drive unit, which drives the drive wheel to rotate. The drive battery powers the entire device. An extended operating port is provided at the center of one end of the electric base 101 to facilitate vertical downward operation of the handheld drilling machine 2. Folding positioning rings are fixedly welded to both sides of the extended operating port.

[0020] This multi-functional rock and soil geological drilling rig is powered by a drive battery within the electric base 101. Control components allow for the movement and positioning of the electric operating frame 1, while four corner wheels facilitate easy movement to the work position. Placing the handheld drilling rig 2 at the extended operating port at the center of one end of the electric base 101 allows for vertical downward drilling. A folding positioning ring can be used to fix or assist in positioning related components. This structure makes the drilling rig easy to move and accurately positioned, enabling efficient completion of rock and soil geological drilling work.

[0021] An angle-adjusting bracket 102 has its bottom end hinged to the front end of the upper surface of the electric base 101, and an angle-adjusting motor 103 for controlling and adjusting the working direction of the handheld drilling machine 2 is fixedly installed on one side of its top end; the lower inner side of the angle-adjusting bracket 102 is hinged to the electric base 101, and when it is in a vertical state, its lower surface is in contact with the upper surface of the electric base 101; positioning mounting holes are opened on both sides of the upper end of the angle-adjusting bracket 102 at positions corresponding to the output end of the angle-adjusting motor 103; and a fixing threaded hole is designed on the lower side of the angle-adjusting motor 103 in the angle-adjusting bracket 102.

[0022] In use, the angle adjustment bracket 102 can rotate flexibly due to its hinged connection with one end of the upper surface of the electric base 101. The angle adjustment motor 103 is fixed to one side of the upper end of the angle adjustment bracket 102, and its output end corresponds to the position of the positioning mounting hole. By operating the angle adjustment motor 103, the working direction of the handheld drilling machine 2 can be precisely controlled and adjusted to meet the drilling needs of different angles. The lower surface of the angle adjustment bracket 102 is in contact with the upper surface of the electric base 101 to enhance structural stability. The hinged connection between the lower inner side and the electric base 101 ensures smooth rotation. At the same time, the fixed threaded hole can be used to install and fix other auxiliary components, further improving the flexibility and reliability of drilling operations.

[0023] The stabilizing support rod 104 has its bottom end hinged to the rear end of the electric base 101, and its top end connected to the upper end of the angle adjustment bracket 102 by bolts; a connecting threaded hole is opened in the middle and upper part of the stabilizing support rod 104, and a connecting bolt is installed in the threaded hole. The position of the connecting threaded hole corresponds to the position of the folding positioning ring.

[0024] In use, according to actual operational needs, the upper end of the stabilizing support rod 104 is installed on the fixing threaded hole of the angle adjustment bracket 102 through the connecting threaded hole and connecting bolt, thereby constructing a stable triangular support structure. This structure can effectively enhance the stability of the drilling rig during operation, reduce shaking and displacement, and ensure that the handheld drilling machine 2 can maintain a precise and stable operating state during drilling, thereby improving the quality and safety of drilling operations.

[0025] The electric slide rail 105 is rotatably connected to the angle adjustment bracket 102 at its upper end, and a positioning mounting plate 106 is slidably disposed inside it. A fixing groove is vertically formed inside the positioning mounting plate 106 for fixing and limiting the handheld drilling machine 2. The electric slide rail 105 includes: a mounting rail with rotating mounting shafts integrally designed on both sides of its upper end. The rotating mounting shafts are rotatably disposed inside the positioning mounting hole, and the ends of the rotating mounting shafts are fixedly connected to the output end of the angle adjustment motor 103; and an electric threaded rod disposed inside the mounting rail and connected to the positioning mounting plate 106 by threads for driving the positioning mounting plate 106 to reciprocate on the mounting rail to adjust the working position of the handheld drilling machine 2.

[0026] In use, the angle-adjusting motor 103 drives the rotating mounting shaft, which in turn rotates the electric slide rail 105 to a suitable angle, allowing the handheld drill 2 to be inserted into the fixed slot of the positioning mounting plate 106 for limiting its position. Then, the electric threaded rod is activated, and its threaded connection with the positioning mounting plate 106 causes the positioning mounting plate 106 to reciprocate within the mounting slide rail, thereby precisely adjusting the working position of the handheld drill 2. This structure can flexibly change the working angle of the handheld drill 2 and precisely adjust its position, making drilling operations more efficient and accurate, and meeting diverse rock and soil geological drilling needs.

[0027] The combination structure 107 is disposed inside the positioning mounting plate 106 for fixing the handheld drilling machine 2. The combination structure 107 includes a combination clamping plate 1071, which has transverse sliding grooves designed at both ends of the fixing groove. The combination clamping plate 1071 is slidably installed inside the transverse sliding grooves, and its lower surface is in contact with the lower inner surface of the operating handle 204. A telescopic threaded hole is opened transversely inside for pushing the combination clamping plate 1071 to move. The control screw 1072 has an operating through hole at one end of the transverse slide groove that corresponds to the position of the telescopic threaded hole. One end of the control screw 1072 is rotatably fitted inside the control screw 1072, and the other end is threaded to the telescopic threaded hole.

[0028] When using the combined structure 107, the handheld drilling machine 2 is placed into the fixed slot of the positioning mounting plate 106. The control screw 1072 is rotated through the operating through hole at one end of the transverse slide. Since one end of the control screw 1072 is rotated and locked in the transverse slide, and the other end is threadedly connected to the telescopic threaded hole in the combined plate 1071, rotating the control screw 1072 will push the combined plate 1071 to slide in the transverse slide until the lower surface of the combined plate 1071 is tightly fitted with the lower inner surface of the operating handle 204 of the handheld drilling machine 2, thereby firmly fixing the handheld drilling machine 2. This structure can ensure that the drilling machine is stable and does not shake during operation, improving the accuracy and safety of drilling operations.

[0029] Handheld drilling rig 2 includes: The drilling machine body 201 is equipped with a power battery 2011, a drilling motor 2012 and a drill rod 2013. The output shaft of the drilling motor 2012 is fixedly connected to one end of the drill rod 2013. The drill rod fixing sleeve 202 is set at the output end of the drilling machine body 201. It has a fixing hole inside that matches the drill rod 2013. A fixing bolt is inserted into the fixing hole. One end of the drill rod 2013 is designed with a mounting block. A mounting through hole corresponding to the fixing hole is opened inside the mounting block. The fixing bolt passes through the mounting through hole.

[0030] When using this handheld drilling machine 2, first insert the end of the drill rod 2013 with the mounting clip into the fixing hole of the drill rod fixing sleeve 202, aligning the mounting through hole with the fixing hole. Then insert and tighten the fixing bolt to securely fix the drill rod 2013 to the output end of the drilling machine body 201. The power battery 2011 supplies power to the drilling motor 2012. When the drilling motor 2012 runs, its output shaft drives the drill rod 2013 to rotate, thereby carrying out drilling operations. This structure, through the cooperation of the drill rod fixing sleeve 202 and the fixing bolt, ensures that the drill rod 2013 is securely installed, preventing it from loosening and falling off during operation, and ensuring stable and efficient drilling work.

[0031] The sampling sleeve 203 is fitted over the drill pipe 2013 for sample storage. The lower outer side of the drilling machine body 201 is integrally designed with a threaded tube. The upper end of the sampling sleeve 203 is provided with an external hexagonal threaded tube that can be threaded to the threaded tube. At the same time, the lower end of the sampling sleeve 203 is chamfered.

[0032] In use, align the external hexagonal threaded tube at the upper end of the sampling sleeve 203 with the assembly threaded tube at the lower end of the drilling machine body 201 and tighten them by rotation, so that the sampling sleeve 203 is securely fitted on the outside of the drill rod 2013; the chamfered treatment at its lower end can reduce the resistance when inserting into the formation, making it easier to enter the drilling position; this structure can effectively collect and store the samples generated during the drilling process, preventing the samples from scattering or mixing, the threaded connection method ensures convenient installation and disassembly and a firm connection, and the chamfer design optimizes the smoothness of operation, improves sampling efficiency and sample integrity.

[0033] The operating handle 204 is integrated on the outer surface of the drilling machine body 201 and can be fixedly installed inside the combined structure 107. The outer side of the operating handle 204 is S-shaped, and its lower surface fits together with the inner surface of the fixing slot.

[0034] The control panel 205 is located on the upper surface of the drilling machine body 201 and is used to control the start and stop of the drilling motor 2012.

[0035] In use, the handheld drilling machine 2 is placed in the fixing slot of the positioning mounting plate 106. Because the outer side of the operating handle 204 is S-shaped and the lower surface fits against the inner surface of the fixing slot, it can be firmly locked in. It is further fixed by the combination structure 107. The operator can flexibly control the position and angle of the drilling machine body 201 by holding the operating handle 204. The starting and stopping of the drilling motor 2012 can be conveniently controlled through the operation control panel 205 on the upper surface of the drilling machine body 201, so as to achieve precise operation of drilling. These structures make the drilling machine easy to hold and fix, and the operation and control are intuitive and simple, which improves the convenience and controllability of drilling operations.
