Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a drilling device for civil engineering construction. Background Technology

[0002] In civil construction, drilling is a fundamental step in processes such as structural reinforcement, pipeline pre-embedding, and anchor installation. Traditional construction relies mainly on operators using handheld electric drills or simple bench drills, with the drilling direction entirely controlled manually, resulting in low precision, poor stability, and high labor intensity. To improve work quality, specialized drilling devices have been developed, typically employing rigid frames and guiding mechanisms to fix the drill bit's movement trajectory along a single axis, thus achieving directional automated or semi-automated drilling. In specific scenarios, such as standardized horizontal drilling of walls or vertical drilling of the ground, these devices can effectively improve efficiency and consistency; however, their function is inherently limited to a single direction from the outset, lacking the flexibility to adapt to complex working conditions.

[0003] As construction requirements become increasingly stringent, existing technologies are attempting to expand the functionality of basic drilling rigs. For example, by adding auxiliary swing or translation components, the drill bit can be adjusted to a limited position within the same plane, enabling continuous multi-hole operation within a certain range. Furthermore, designs integrating depth control, dust collection, or grouting functions have emerged, aiming to improve process continuity and the working environment. However, the core limitation of these improvements lies in the fixed posture of the drilling unit relative to the frame. The mechanical structure of the device dictates that the drill bit can only perform a preset, unidirectional linear feed motion, or a small-range planar movement based on that.

[0004] This inherent limitation in direction is a major drawback of current technology in practical applications. Construction sites often face complex tasks requiring drilling at multiple angles on the same working face, such as inclined rock and soil anchoring holes, structural brace connection holes, or alternating horizontal and vertical hole layouts in the same area. Existing devices exhibit significant shortcomings in addressing these needs: operators must prepare or replace specialized equipment for each angle, or perform tedious repositioning, leveling, and fixing of the entire equipment. This not only leads to construction interruptions and significantly reduced efficiency but also results in low equipment utilization and increased storage and transportation costs. More importantly, repeated manual adjustments introduce new errors, affecting hole accuracy and the final structural quality. Therefore, the market urgently needs a drilling device that can overcome the limitation of a single direction and quickly and accurately switch between horizontal, vertical, and even arbitrary inclined angles. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is to provide a drilling device for civil construction, which can provide flexible drilling methods at multiple angles, realize the rapid switching of horizontal, vertical and oblique drilling, significantly improve work efficiency and reduce equipment investment and manual adjustment costs.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A drilling device for civil engineering construction includes a frame, a rotating mechanism, a translating mechanism, and a drilling mechanism;

[0008] The rotating mechanism includes a rotating mounting base fixed on the frame, a vertically arranged turntable rotatably mounted on the rotating mounting base, the turntable being connected to a rotary motor, and a translation mechanism fixed on the turntable. The rotating mechanism is used to drive the translation mechanism to reciprocate around the axis of the turntable.

[0009] The drilling mechanism is mounted on the moving end of the translation mechanism. The translation mechanism is used to drive the drilling mechanism to reciprocate. The drilling mechanism includes a drilling mounting base, on which a drilling motor is mounted. The drilling motor is connected to the drill bit.

[0010] Preferably, the rotary mounting base is a hollow rectangular structure, the rotary motor is installed inside the rotary mounting base, and a bearing seat is installed on the top of the rotary mounting base;

[0011] The turntable includes a disc body and a shaft vertically fixed to one side thereof, the shaft passing through the bearing seat and connected to the rotary motor.

[0012] Preferably, the shaft and the rotary motor are connected by a sprocket and chain mechanism.

[0013] The sprocket and chain mechanism includes a driving sprocket fixed to the rotary motor, a driven sprocket fixed to the shaft, and a transmission chain disposed between the driving sprocket and the driven sprocket.

[0014] Preferably, at least one limiting structure is provided between the disc body and the rotary mounting base;

[0015] The limiting structure includes several limiting holes equidistantly arranged along the circumference of the disc body, and connecting lugs fixed on the rotating mounting base. A limiting bolt passes through one of the limiting holes and is threadedly connected to the connecting lug. A fastening nut is threaded onto the limiting bolt and abuts against the connecting lug.

[0016] Preferably, the disc body is provided with two integrally formed extensions, which are fixedly connected to the translation mechanism.

[0017] Preferably, the translation mechanism includes a translation slide.

[0018] Preferably, the direction of movement of the translation mechanism is perpendicular to the axis of the turntable, and the axial direction of the drill bit is in the same direction as the direction of movement of the translation mechanism.

[0019] Preferably, a protective cover is installed on the drilling mounting base, and the protective cover is located on the outside of the connection between the drilling motor and the drill bit.

[0020] Preferably, the frame is equipped with support feet and casters, the casters are mounted on the outside of the frame, the support feet are mounted on the bottom of the frame, and the height of the support feet is adjustable.

[0021] Preferably, a handle is installed on the top of the frame.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are:

[0023] The drilling device for civil construction of this application includes a frame, a rotating mechanism, a translating mechanism, and a drilling mechanism; wherein, the rotating mechanism includes a rotating mounting base fixed on the frame, a vertically arranged turntable rotatably mounted on the rotating mounting base, the turntable being connected to a rotary motor, the translating mechanism being fixed on the turntable, and the rotating mechanism being used to drive the translating mechanism to reciprocate around the axis of the turntable; the drilling mechanism is mounted on the actuating end of the translating mechanism, and the translating mechanism is used to drive the drilling mechanism to reciprocate, the drilling mechanism including a drilling mounting base, a drilling motor mounted on the drilling mounting base, and the drilling motor being connected to a drill bit.

[0024] First, the operator starts the rotary motor according to the target drilling angle required for the construction. The rotary motor drives the vertically mounted turntable to rotate back and forth around its vertical axis. Since the translation mechanism is fixedly mounted on the turntable, the translation mechanism and its end drilling mechanism rotate as a whole, thereby quickly adjusting the drill bit to the predetermined direction in the horizontal plane. After the direction adjustment is completed, the translation mechanism is started. Its actuating end pushes the drilling mounting base and the drilling motor and drill bit mounted on it, making linear feed motion along the guide rail of the translation mechanism. At the same time, the drilling motor starts, driving the drill bit to rotate at high speed. Under the combined action of rotary cutting and linear feed, the drill bit drills into the ground or wall in the predetermined precise direction, completing the drilling operation. The entire operation cycle is: rotational orientation → locking → translational feed drilling → retraction, realizing multi-angle drilling in a fixed position.

[0025] Through the 360-degree rotation of the rotating mechanism, the drill bit can cover any azimuth angle within the same plane, easily handling horizontal, vertical, and various oblique drilling needs, breaking through the limitations of traditional drilling equipment with fixed direction. Direction adjustment is completed solely through motor control, eliminating the need to move the bulky frame, significantly reducing worker workload and adjustment time. Simultaneously, because the feed direction of the translation mechanism remains strictly aligned with the drill bit's drilling axis, guaranteed by rigid guide rails, the straightness and angular accuracy of the hole are ensured, avoiding deviations caused by manual operation. This modular design decouples direction adjustment from feed functions, resulting in a compact structure, simple control, and high reliability. While significantly improving construction adaptability and drilling quality, it effectively reduces project delays and cost incurred due to replacing specialized equipment or repeated positioning.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] like Figures 1 to 8 As shown, this utility model includes a frame 1, a rotating mechanism 2, a translating mechanism 3, and a drilling mechanism 4. The rotating mechanism 2 includes a rotating mounting base 21 fixed to the frame 1, on which a vertically arranged turntable 22 is rotatably mounted. The turntable 22 is connected to a rotary motor 23. The translating mechanism 3 is fixed to the turntable 22 and is used to drive the translating mechanism 3 to reciprocate around the axis of the turntable 22. The drilling mechanism 4 is mounted on the actuating end of the translating mechanism 3 and is used to drive the drilling mechanism 4 to reciprocate. The drilling mechanism 4 includes a drilling mounting base 41, on which a drilling motor 42 is mounted. The drilling motor 42 is connected to a drill bit 43.

[0044] First, the operator starts the rotary motor 23 according to the target drilling angle required for construction. The rotary motor 23 drives the vertically mounted turntable 22 to reciprocate around its vertical axis. Since the translation mechanism 3 is fixedly mounted on the turntable 22, the translation mechanism 3 and its end drilling mechanism 4 rotate as a whole, thereby quickly adjusting the drill bit 43 to the predetermined direction in the horizontal plane. After the direction adjustment is completed, the translation mechanism 3 is started, and its actuating end pushes the drilling mounting base 41 and the drilling motor 42 and drill bit 43 mounted on it to make linear feed motion along the guide rail direction of the translation mechanism 3. At the same time, the drilling motor 42 starts, driving the drill bit 43 to rotate at high speed. Under the combined action of rotary cutting and linear feed, the drill bit 43 drills into the ground or wall in the predetermined precise direction, completing the drilling operation. The entire operation cycle is: rotational orientation → locking → translational feed drilling → retraction, realizing multi-angle drilling in a fixed position.

[0045] Through the 360-degree rotation of the rotating mechanism 2, the drill bit 43 can cover any azimuth angle within the same plane, easily handling horizontal, vertical, and various oblique drilling needs, breaking through the limitations of fixed direction in traditional drilling equipment. Direction adjustment is completed solely through motor control, eliminating the need to move the bulky frame 1, significantly reducing worker workload and adjustment time. Simultaneously, because the feed direction of the translation mechanism 3 remains strictly aligned with the drilling axis of the drill bit 43, and is guaranteed by rigid guide rails, the straightness and angular accuracy of the hole are ensured, avoiding deviations caused by manual operation. This modular design decouples direction adjustment from feed functions, resulting in a compact structure, simple control, and high reliability. While significantly improving construction adaptability and drilling quality, it effectively reduces project delays and cost incurred due to replacing specialized equipment or repeated positioning.

[0046] Preferably, the rotary mounting base 21 is a hollow rectangular structure. The rotary motor 23 is installed inside the rotary mounting base 21, and a bearing seat 24 is installed on the top of the rotary mounting base 21. The turntable 22 includes a disc body 221 and a shaft 222 vertically fixed to one side of it. The shaft 222 passes through the bearing seat 24 and connects to the rotary motor 23. The rotary mounting base 21 adopts a hollow rectangular structure, and the rotary motor 23 is installed inside it. This layout improves the compactness of the structure and the space utilization. The rectangular base provides stable support, and the bearing seat 24 installed on its top cooperates with the shaft 222 of the turntable 22 to form a stable rotational support, ensuring that the turntable can rotate smoothly and accurately under load, providing a basis for accurate positioning of the drilling angle. The shaft 222 is directly connected to the rotary motor 23, with a short transmission path and rapid response, which is conducive to achieving rapid directional adjustment. At the same time, the modular split design facilitates the independent assembly, disassembly, and maintenance of key components, improving the reliability and service life of the whole machine.

[0047] The shaft 222 is connected to the rotary motor 23 by a sprocket and chain mechanism 5. The sprocket and chain mechanism 5 includes a drive sprocket 51 fixed on the rotary motor 23, a driven sprocket 52 fixed on the shaft 222, and a transmission chain 53 disposed between the drive sprocket 51 and the driven sprocket 52.

[0048] At least one limiting structure 6 is provided between the disc body 221 and the rotary mounting base 21. The limiting structure 6 includes several limiting holes 61 equidistantly arranged along the circumference of the disc body 221, a connecting lug 62 fixed on the rotary mounting base 21, a limiting bolt 63 passing through one of the limiting holes 61 and threadedly connected to the connecting lug 62, and a fastening nut 64 threadedly connected to the limiting bolt 63 and abutting against the connecting lug 62.

[0049] The limiting structure 6 achieves reliable angle locking and rapid positioning of the turntable 22 through simple mechanical cooperation. Specifically, several limiting holes 61 evenly distributed around the circumference of the disc 221 provide multiple preset, precisely indexed fixed positions, allowing the turntable 22 to be stably locked at multiple common or specific angles. When the rotary motor 23 drives the turntable 22 to the target position, the operator only needs to pass the limiting bolt 63 through the corresponding limiting hole 61 and screw it into the connecting lug 62 on the rotary mounting base 21, and then tighten the fastening nut 64 to make it abut against the connecting lug 62 to complete the mechanical locking. This structure can effectively resist the vibration and rotational reaction force generated during drilling, preventing the turntable from accidentally shifting during operation, thereby ensuring the high accuracy of the drilling direction. At the same time, its simple structure, low manufacturing cost, intuitive and reliable operation, and lack of complex electrical or hydraulic locking devices make it easy to install, adjust and maintain on site, improving the practicality and economy of the entire equipment.

[0050] Preferably, there are two limiting structures 6, which are respectively located on both sides of the rotating mounting base 21.

[0051] The disk body 221 is provided with two integrally formed extensions 223, which are fixedly connected to the translation mechanism 3. The translation mechanism 3 includes a translation slide.

[0052] Two integrally formed extensions 223 on the disc 221 are fixedly connected to the translation mechanism 3, achieving a rigid and integrated transition between the rotary mechanism 2 and the translation mechanism 3. The integral forming ensures that there are no gaps or loosening between the extensions 223 and the disc 221, resulting in high overall rigidity. This effectively transmits torque and withstands the radial and axial loads generated during drilling operations, ensuring that the entire drive system does not deform or shift during the rotation of the turntable 22 and the feed of the drill bit 43. The symmetrically arranged extensions 223 make the force distribution on the translation mechanism 3 more balanced and improve installation stability. Using a translation slide as the translation mechanism 3 directly provides high-precision, repeatable linear feed motion. Combined with the rotary mechanism 2, it achieves a precise collaborative operation mode of "rotational angle adjustment – ​​linear feed control," providing a reliable mechanical motion basis for precise and stable drilling in different directions.

[0053] The translation mechanism 3 moves in a direction perpendicular to the axis of the rotary table 22, and the drill bit 43 moves in the same direction as the translation mechanism 3. By limiting the direction of movement of the translation mechanism 3 to be perpendicular to the rotation axis of the rotary table 22, the linear feed motion of the translation mechanism 3 is always within a plane orthogonal to the rotation axis. Simultaneously, the axis of the drill bit 43 is set to be in the same direction as the translation mechanism 3, meaning that the central axis of the drill bit 43, the feed direction of the translation mechanism 3, and the radial direction of the rotary table 22 (after locking) are all aligned.

[0054] This achieves a high degree of consistency between angle adjustment and drilling direction. After the rotary table 22 rotates to set the drilling azimuth angle, the translation mechanism 3 drives the drill bit 43 to advance linearly along its axis. The drilling path of the drill bit 43 will strictly extend along the radial direction of the rotary table 22 at that azimuth. This not only theoretically ensures that the drill bit 43 can accurately enter the hole at the preset angle, but also completely eliminates the deviation in the hole formation trajectory caused by the coupling deviation of the mechanism movement in engineering practice. By simply adjusting the angle through the rotary mechanism 2, a straight hole in that direction can be obtained directly and reliably without secondary calibration, greatly simplifying the operation and fundamentally guaranteeing the hole formation accuracy of various oblique, horizontal, and vertical drilling.

[0055] A protective cover 44 is installed on the drilling mounting base 41. The protective cover 44 is located on the outside of the connection between the drilling motor 42 and the drill bit 43 to protect the connection point. It effectively prevents the drill bit 43 from breaking, debris from flying, or coolant from scattering during operation, ensuring the safety of personnel and equipment. Simultaneously, it prevents dust, mud, and other impurities from entering the connection between the motor output shaft and the drill bit 43, avoiding decreased clamping force, difficulty in disassembly, or abnormal wear, thus ensuring reliable connection and extending the service life of critical components. Furthermore, the protective cover 44 also serves as a clear visual warning and physical isolation, marking the high-speed rotating danger zone. This structure, with its simple implementation, significantly improves the safety, operational reliability, and overall durability of the equipment under actual working conditions.

[0056] The frame 1 is equipped with support feet 11 and casters 12. The casters 12 are mounted on the outside of the frame 1, and the support feet 11 are mounted on the bottom of the frame 1. The height of the support feet 11 is adjustable, and a handle 13 is mounted on the top of the frame 1. The casters 12 on the outside allow the entire device to move and turn easily and flexibly on the construction site, facilitating quick changes of work position. The height of the support feet 11 is adjustable; after the equipment is moved to the predetermined position, the height of the support feet 11 can be adjusted to ensure stable support on the ground, effectively adapting to uneven ground conditions and ensuring the machine remains stable and does not wobble during drilling operations. The handle 13 mounted on the top of the frame 1 provides a convenient point of leverage for manually pushing the equipment. This allows for quick and reliable switching between "flexible movement" and "stable operation" modes, significantly improving the convenience and efficiency of on-site use.

[0057] In use, the operator starts the rotary motor 23 according to the required drilling direction, driving the turntable 22 to rotate around its axis via the sprocket and chain mechanism 5. This causes the translation mechanism 3 fixed on it and the drilling mechanism 4 at the end to rotate as a whole, adjusting the drill bit 43 to the target angle in the horizontal plane. Subsequently, the limiting bolt 63 is passed through the corresponding limiting hole 61 on the disc body 221 and tightened with the connecting lug 62 to complete the mechanical locking of the turntable 22. Next, the translation mechanism 3 is started, and its moving end pushes the drilling mounting base 41 to make linear feed along the guide rail. At the same time, the drilling motor 42 drives the drill bit 43 to rotate at high speed, so that the drill bit drills into the ground or wall in the pre-set precise direction. After drilling is completed, the translation mechanism 3 drives the drilling mechanism 4 to retract. After releasing the limiting structure 6, the above process can be repeated to perform the next angle operation, realizing efficient and precise drilling of multiple angles and multiple holes in a fixed position.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
