Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining technology, specifically to an underground mining tunneling device. Background Technology
[0002] Underground mining refers to the operation of mining mineral resources (such as coal, metal ores, and non-metallic minerals) below the surface (such as underground mines or shafts). The underground ore body is surrounded by rock and cannot be directly mined. A series of underground tunnels must be excavated first, which requires the use of tunneling equipment.
[0003] Chinese patent discloses an underground mining tunneling device (publication number CN211342749 U). This patented technology allows the pull rod to be disengaged from the pin hole by pulling it out, thereby changing the angle of the reversing plate. During the drilling process, holes can be drilled at different positions as needed, so that the screw can be as perpendicular as possible to the mine wall. However, the angle adjustment depends on the pull rod being aligned with the new pin hole. Since the pin holes are discretely distributed and not continuous, it can only achieve fixed angle switching and cannot perform stepless fine adjustment according to actual working conditions. The limitation of pin hole positioning can easily lead to a decrease in the accuracy of angle adjustment. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An underground mining tunneling device, comprising:
[0006] A base is provided, with an outer shell connected to the top of the base. A bearing is connected to the top of the outer shell, and a shaft is rotatably connected inside the bearing. A drive mechanism is provided at the bottom of the shaft, and a rotating plate is connected to the top of the shaft. A base plate is slidably connected above the rotating plate, and a tunneling motor is connected above the base plate. One end of the output shaft of the tunneling motor is connected to a tunneling drill rod, and an electric push rod is connected to the back side of the rotating plate. One end of the electric push rod passes through the interior of the rotating plate and is fixedly connected to the tunneling motor.
[0007] A protective mechanism is provided above the rotating plate and at the top of the tunneling motor;
[0008] The base has four self-locking casters at its bottom, and a handle is attached to the top of the base on the back of the housing.
[0009] In one possible implementation, the drive mechanism includes a servo motor, the bottom of which is connected to a fixed base, the top of which is fixedly connected to a housing, one end of the output shaft of the servo motor is connected to a gear, the outer side of which is meshed with a gear ring, and the inner side of which is fixedly connected to a shaft.
[0010] In one possible implementation, a pair of rectangular sliders are connected to the bottom of the base plate, and a rectangular slide rail is slidably connected to the bottom of the rectangular sliders. The bottom of the rectangular slide rail is fixedly connected to the rotating plate.
[0011] In one possible implementation, the bottom of the rotating plate is connected to an annular slider, the bottom of the annular slider is slidably connected to an annular slide rail, and the bottom of the annular slide rail is fixedly connected to the outer casing.
[0012] In one possible implementation, the axis of the annular slider is aligned with the axis of the shaft.
[0013] In one possible implementation, the protective mechanism includes a guard rail plate with ten through holes at its top. A guide rod is slidably connected inside each through hole. A protective plate is connected to the top of each guide rod. A return spring is sleeved on the outside of each guide rod. The top end of the return spring is fixedly connected to the protective plate, and the bottom end of the return spring is fixedly connected to the guard rail plate.
[0014] In one possible implementation, the bottom of the shorter guard plate is fixedly connected to the rotating plate, and the bottom of the longer guard plate is connected to a pair of support rods, the bottom of which is fixedly connected to the rotating plate.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. By turning on the servo motor, the gear is driven to rotate. Through the cooperation between the gear and the gear ring, the shaft and the top rotating plate can be easily rotated. This, in turn, can easily drive the top tunneling motor and the tunneling drill rod to rotate continuously at any angle, which is conducive to stepless fine adjustment and greatly improves the angle accuracy.
[0017] 2. By setting an annular slider at the bottom of the rotating plate and an annular slide rail that can slide circumferentially at the bottom of the annular slider, when the servo motor drives the rotating plate to rotate, the annular slide rail guides the annular slider to move along a fixed trajectory, ensuring that the angle adjustment process is linear and smooth, reducing the angle deviation caused by vibration or off-center load, and further improving the adjustment accuracy.
[0018] 3. By installing guard plates on the top of the tunneling motor and rectangular slide rail, and installing several return springs on the top of the guard plates, and installing protective plates on the top of the return springs, the protective plates are located on the top layer. When the protective plates are impacted by falling objects, the springs will be compressed and deformed due to external force, which helps to buffer and unload the force and reduce impact damage. At the same time, it blocks most of the falling gravel or rocks, preventing them from directly hitting the tunneling motor, guard plates, or rectangular slide rail below. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This application provides an underground mining tunneling device to solve the problems in the prior art.
[0029] The technical solution in this application is to solve the above problems, and the overall approach is as follows:
[0030] like Figures 1-5 As shown, an underground mining tunneling device includes:
[0031] A base 7 is attached to a housing 6 on top of the base 7. A bearing 14 is attached to the top of the housing 6. A shaft 16 is rotatably connected inside the bearing 14. A drive mechanism is installed at the bottom of the shaft 16. A rotating plate 10 is attached to the top of the shaft 16. A base plate 3 is slidably connected above the rotating plate 10. A tunneling motor 2 is attached to the top of the base plate 3. One end of the output shaft of the tunneling motor 2 is connected to a tunneling drill rod 5. An electric push rod 11 is attached to the back side of the rotating plate 10. One end of the electric push rod 11 passes through the interior of the rotating plate 10 and is fixedly connected to the tunneling motor 2. When the tunneling motor 2 is turned on, the tunneling drill rod 5 is driven to rotate. At the same time, the electric push rod 11 is turned on to facilitate pushing the tunneling drill rod 5 to rotate forward, thereby achieving the tunneling effect.
[0032] A protective mechanism is provided above the rotating plate 10 and at the top of the tunneling motor 2;
[0033] The bottom of the base 7 is connected to four self-locking casters 8, and the top of the base 7 is connected to the back of the outer casing 6 with a handle 12.
[0034] In some examples, the drive mechanism includes a servo motor 18, with a fixed base 19 connected to the bottom of the servo motor 18. The top of the fixed base 19 is fixedly connected to the housing 6. One end of the output shaft of the servo motor 18 is connected to a gear 17. A gear ring 15 is meshed with the outer side of the gear 17. The inner side of the gear ring 15 is fixedly connected to the shaft 16. When the servo motor 18 is turned on, the gear 17 is driven to rotate. Through the cooperation between the gear 17 and the gear ring 15, the shaft 16 and the rotating plate 10 at the top can be easily rotated. This facilitates the continuous rotation of the tunneling motor 2 and the tunneling drill rod 5 at the top to any angle, which is beneficial for stepless fine adjustment and greatly improves the angle accuracy.
[0035] In some examples, a pair of rectangular sliders 23 are connected to the bottom of the base plate 3, and a rectangular slide rail 4 is slidably connected to the bottom of the rectangular sliders 23. The bottom of the rectangular slide rail 4 is fixedly connected to the rotating plate 10.
[0036] In some examples, the bottom of the rotating plate 10 is connected to an annular slider 24, and the bottom of the annular slider 24 is slidably connected to an annular slide rail 25. The bottom of the annular slide rail 25 is fixedly connected to the housing 6. When the servo motor 18 drives the rotating plate 10 to rotate, the annular slide rail 25 guides the annular slider 24 to move along a fixed trajectory, ensuring that the angle adjustment process is linear and smooth, reducing the angle deviation caused by vibration or off-center load, and further improving the adjustment accuracy.
[0037] In some examples, the axis of the annular slider 24 is aligned with the axis of the shaft 16.
[0038] In some examples, the protective mechanism includes a guard rail plate 13 with ten through holes 22 at its top. Guide rods 20 are slidably connected inside the through holes 22. A protective plate 1 is connected to the top of the guide rods 20. A return spring 21 is sleeved on the outside of the guide rods 20. The top end of the return spring 21 is fixedly connected to the protective plate 1, and the bottom end of the return spring 21 is fixedly connected to the guard rail plate 13. The protective plate 1 is located at the top layer. When the protective plate 1 is impacted by falling objects, the return spring 21 will be compressed and deformed by the external force, which helps to buffer and unload the force and reduce impact damage. At the same time, it blocks most of the falling gravel or rocks, preventing them from directly hitting the excavation motor 2, the guard rail plate 13, or the rectangular slide rail 4 below.
[0039] In some examples, the bottom of the shorter guard rail plate 13 is fixedly connected to the rotating plate 10, and the bottom of the longer guard rail plate 13 is connected to a pair of support rods 9, the bottom of which is fixedly connected to the rotating plate 10, which helps to increase the overall stability of the guard rail plate 13.
[0040] This invention activates the servo motor 18, driving the gear 17 to rotate. Through the cooperation between the gear 17 and the gear ring 15, the shaft 16 and the top rotating plate 10 are easily rotated, which in turn facilitates the continuous rotation of the top tunneling motor 2 and the tunneling drill rod 5 to any angle. This allows for stepless fine-tuning and significantly improves angle accuracy. When the servo motor 18 drives the rotating plate 10 to rotate, the annular slide rail 25 guides the annular slider 24 to move along a fixed trajectory, ensuring a linear and smooth angle adjustment process and reducing angle deviations caused by vibration or off-center load, further improving adjustment accuracy.
[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
