Description

Technical Field

[0001] This utility model relates to the field of underground engineering technology, and in particular to a novel underground drilling machine. Background Technology

[0002] Underground engineering refers to various engineering spaces and facilities constructed below the ground level in soil or rock strata; it is a general term for projects built within underground strata. It includes mining tunnel engineering, urban subway tunnel engineering, hydraulic tunnel engineering, transportation mountain tunnel engineering, hydroelectric underground chamber engineering, underground space engineering, and underground military and defense engineering, among others. During the construction of underground projects, drilling rigs may sometimes be used to drill holes in the ground.

[0003] Among existing Chinese utility models, CN210969450U discloses an underground drilling device, including a handle I, a shoulder strap, a handle II, a lighting lamp, a water pipe clamp, a drill bit, a motor I, a moving frame, a threaded column, a motor II, springs, a fixed pipe, a support frame, and telescopic rods. The drill bit is fixedly connected to the output shaft of motor I, the moving frame is fixedly connected to the rear end of motor I, the threaded column is drivenly connected to the moving frame, the threaded column is fixedly connected to the output shaft of motor II, the handle II is fixedly connected to the middle of the support frame, three telescopic rods are circumferentially fixedly connected to the front end of the support frame, three springs are respectively sleeved on the three telescopic rods, motor I is slidably connected inside the support frame, the fixed pipe is fixedly connected to the rear end of the support frame, motor II is fixedly connected inside the fixed pipe, and the handle I is fixedly connected to the middle of the upper end of the fixed pipe. This device improves the working stability of the drilling rig on non-planar surfaces and has high working efficiency.

[0004] Referring to the aforementioned underground drilling device, this device is supported by telescopic rods and springs. However, during pressing, it is difficult to ensure that the three springs experience equal force. If different forces are applied to the three springs, the compression degrees of the springs will be uneven, causing the threaded column to shift during drilling and resulting in borehole tilting. Furthermore, when the telescopic rods and springs are supported on uneven ground, it is difficult to ensure that the drilling device is in a horizontal position, thus failing to guarantee that the threaded column is in a vertical position and does not tilt. Therefore, how to ensure that the drilling device is in a horizontal position and prevent the threaded column from tilting during drilling are important problems that need to be solved in the design of new underground drilling machines. Utility Model Content

[0005] This invention provides a novel underground drilling machine to address the problems of not being able to adequately ensure that the drilling device is in a horizontal position and the possibility of the threaded column tilting during the drilling process.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a novel underground drilling machine, including a support plate, and further comprising:

[0008] A drilling structure is provided in the center of the support plate;

[0009] A support structure is disposed on the outside of the drilling structure;

[0010] A transmission structure is disposed between the drilling structure and the support structure.

[0011] Preferably, a support frame and a fixing frame are fixedly connected to the top side wall of the support plate, and the support frame is located in the middle of the support plate.

[0012] In this technical solution, the support frame supports the rotating motor.

[0013] Preferably, a leveling instrument is fixedly connected to the center of the top side wall of the support frame.

[0014] In this technical solution, the level detector is used to detect whether the support plate is in a horizontal state.

[0015] Preferably, the drilling structure includes a drilling screw, a rotating rod, a second rotating gear, and a rotating motor. The rotating motor is fixedly connected to the top inner side wall of the support frame. The rotating end of the rotating motor is fixedly connected to the rotating rod. The rotating rod is rotatably connected to the center of the side wall of the support plate. The bottom of the rotating rod is fixedly connected to the drilling screw, and the second rotating gear is fixedly connected to the side wall of the rotating rod.

[0016] In this technical solution, the rotation of the motor drives the rotation of the rotating rod, which in turn drives the rotation of the second rotating gear and the drilling screw.

[0017] Preferably, the transmission structure includes a transmission gear ring, a transmission gear, a connecting ring frame, and a connecting rod. The connecting ring frame and the connecting rod are rotatably connected to the top side wall of the support plate. The connecting rod is located inside the connecting ring frame. The transmission gear ring is fixedly connected to the top of the connecting ring frame, and the transmission gear is fixedly connected to the top side wall of the connecting rod.

[0018] Preferably, the outer and inner rings of the transmission gear ring are provided with rotating tooth grooves on their side walls, and the transmission gear meshes with the rotating tooth grooves on the inner ring of the transmission gear ring.

[0019] In this technical solution, the rotation of the second rotating gear drives the transmission gears on both sides to rotate. The transmission gears rotate in the rotating tooth grooves on the inner ring of the transmission gear ring, thereby driving the transmission gear ring to rotate.

[0020] Preferably, the transmission gear is located on both sides of the rotating gear two, and the transmission gear and the rotating gear two mesh with each other.

[0021] Preferably, the support structure includes a rotating gear and a threaded sleeve. Three threaded sleeves are rotatably connected at equal intervals on the side wall of the support plate. The bottom side wall of the threaded sleeve is circular and expands outward. The top of the threaded sleeve is fixedly connected to the rotating gear.

[0022] Preferably, the rotating gear meshes with the rotating tooth groove on the outer ring of the transmission gear ring.

[0023] In this technical solution, the rotating tooth groove on the outer ring of the transmission gear ring rotates along the rotating gear, driving the three rotating gears to rotate synchronously, and the rotating gear drives the threaded sleeve to rotate.

[0024] Preferably, the support structure includes a first fixed plate, a sliding rod, a threaded rod, a second fixed plate, a second support frame, and an electric push rod. The threaded rod is threadedly connected to the rotating gear and the side wall of the threaded sleeve. The top of the threaded rod is fixedly connected to the first fixed plate, and the bottom of the second threaded rod is fixedly connected to the second fixed plate. A sliding rod is fixedly connected between the first fixed plate and the second fixed plate, and the sliding rod is slidably connected to the side wall of the support plate. The sliding rod is located on both sides of the threaded rod. The bottom of the second fixed plate is fixedly connected to the electric push rod, and the bottom of the electric push rod is fixedly connected to the second support frame. The second support frame is slidably connected to the second fixed plate.

[0025] In this technical solution, the three electric push rods are adjusted respectively. By extending or shortening the length of the three electric push rods, the second support frame is moved, thereby adjusting the support plate to a horizontal state. The threaded sleeve rotates on the threaded rod, causing the three threaded rods to rise synchronously. As the threaded rods rise, the distance between the support plate and the ground is shortened, while the support plate is always kept in a horizontal state.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] 1. Use a leveling instrument to check if the support plate is level. If it is not level, adjust the three electric push rods. By extending or shortening the length of the three electric push rods, the support frame 2 will move, thereby adjusting the support plate to a level position. This ensures that the support plate is level, and the drilling screw is vertical and does not tilt.

[0029] 2. The rotation of the motor drives the second rotating gear and the drilling screw to rotate. The rotation of the second rotating gear drives the transmission gear to rotate, which in turn drives the transmission gear ring to rotate. The transmission gear ring drives the three first rotating gears to rotate synchronously. The first rotating gear drives the threaded sleeve to rotate, and the threaded sleeve drives the three threaded rods to rise synchronously. This makes it easier to shorten the distance between the support plate and the ground while keeping the support plate in a horizontal state, thereby preventing the drilling screw from tilting during the drilling process.

[0045] The rotating motor 504 rotates, which drives the rotating rod 502 to rotate. The rotating rod 502 drives the rotating gear 503 and the drilling screw 501 to rotate.

[0046] The transmission structure 6 includes a transmission gear ring 601, a transmission gear 602, a connecting ring frame 603, and a connecting rod 604. The connecting ring frame 603 and the connecting rod 604 are rotatably connected to the top side wall of the support plate 1. The connecting rod 604 is located inside the connecting ring frame 603. The transmission gear ring 601 is fixedly connected to the top of the connecting ring frame 603, and the transmission gear 602 is fixedly connected to the top side wall of the connecting rod 604.

[0047] Rotating tooth grooves are provided on the side walls of both the outer and inner rings of the transmission gear ring 601, and the transmission gear 602 meshes with the rotating tooth grooves on the inner ring of the transmission gear ring 601.

[0048] The rotation of the second rotating gear 503 drives the rotation of the transmission gears 602 on both sides. The transmission gears 602 rotate in the rotating tooth grooves on the inner ring of the transmission gear ring 601, thereby driving the transmission gear ring 601 to rotate.

[0049] The transmission gear 602 is located on both sides of the rotating gear 503, and the transmission gear 602 and the rotating gear 503 mesh with each other.

[0050] The support structure 4 includes a rotating gear 401 and a threaded sleeve 402. Three threaded sleeves 402 are rotatably connected at equal intervals on the side wall of the support plate 1. The bottom side wall of the threaded sleeve 402 is circular and expands outward. The top of the threaded sleeve 402 is fixedly connected to the rotating gear 401.

[0051] The rotating gear 401 meshes with the rotating tooth groove on the outer ring of the transmission gear ring 601.

[0052] The rotating tooth groove on the outer ring of the transmission gear ring 601 rotates along the rotating gear 401, driving the three rotating gears 401 to rotate synchronously, and the rotating gears 401 drive the threaded sleeve 402 to rotate.

[0053] The support structure 4 includes a first fixed plate 411, a sliding rod 412, a threaded rod 413, a second fixed plate 414, a second support frame 415, and an electric push rod 416. The threaded rod 413 is threadedly connected to the side wall of the first rotating gear 401 and the threaded sleeve 402. The top of the threaded rod 413 is fixedly connected to the first fixed plate 411, and the bottom of the second threaded rod 413 is fixedly connected to the second fixed plate 414. The sliding rod 412 is fixedly connected between the first fixed plate 411 and the second fixed plate 414.

The bottom of the second fixed plate 414 is fixedly connected to the electric push rod 416, and the bottom of the electric push rod 416 is fixedly connected to the second support frame 415. The second support frame 415 is slidably connected to the second fixed plate 414.

[0054] The three electric push rods 416 are adjusted respectively. By extending or shortening the length of the three electric push rods 416, the support frame 415 is moved, thereby adjusting the support plate 1 to a horizontal state. The threaded sleeve 402 rotates on the threaded rod 413, causing the three threaded rods 413 to rise synchronously. As the threaded rods 413 rise, the distance between the support plate 1 and the ground is shortened, while the support plate 1 is always kept in a horizontal state.

[0055] In use, all electrical components mentioned in this application are connected to an external power supply and control switch. The three support frames 415 are placed against the ground. The support plate 1 is placed horizontally by the level detector 7. If it is not horizontal, the three electric push rods 416 are adjusted. By extending or shortening the length of the three electric push rods 416, the support frame 415 is moved, thereby adjusting the support plate 1 to a horizontal state. At this time, the drilling screw 501 is in a vertical state and does not tilt. The fixing frame 2 is manually pressed to make the support frame 415 press firmly against the ground.

[0056] The rotating motor 504 drives the rotating rod 502 to rotate, which in turn drives the rotating gear 503 and the drilling screw 501 to rotate. The rotating gear 503 drives the transmission gears 602 on both sides to rotate. The transmission gears 602 rotate in the rotating tooth groove on the inner ring of the transmission gear ring 601, causing the transmission gear ring 601 to rotate. The rotating tooth groove on the outer ring of the transmission gear ring 601 rotates along the rotating gear 401, causing the three rotating gears 401 to rotate synchronously. The rotating gears 401 drive the threaded sleeve 402 to rotate, and the threaded sleeve 402 rotates on the threaded rod 413, causing the three threaded rods 413 to rise synchronously. As the threaded rods 413 rise, the distance between the support plate 1 and the ground is shortened, while the support plate 1 is kept horizontal at all times, thus preventing the drilling screw 501 from tilting during drilling. Combined with the pressing of the fixing frame 2, the rotating drilling screw 501 drills a hole in the ground.
