Description

Technical Field

[0001] This application relates to the field of tilt sensors, and in particular to tilt sensors for mining applications. Background Technology

[0002] Tilt sensors are commonly used to measure angle changes in systems. As a detection tool, they are widely used in industrial automation, aviation and marine engineering, bridge construction, railway laying, civil engineering, oil drilling, machining, mining equipment and other fields. They are an indispensable and important measuring tool for angle measurement.

[0003] Currently, tilt sensors offer linear accuracy of 0.001° to 0.005° and a measurement range of ±90°. For mining equipment, such as hydraulic supports, tilt sensors are typically mounted on the hydraulic boom to convert changes in boom tilt angle into analog-to-digital signals, thus measuring the change in boom tilt angle. Tilt sensors can be installed vertically or horizontally. Regardless of the method, it's crucial to ensure the tilt sensor is parallel to the surface of the object being measured. Simultaneously, the X-axis and Y-axis of the tilt sensor must be parallel to the X-axis and Y-axis of the object being measured, respectively. For irregularly shaped surfaces, such as curved surfaces, the tilt sensor must be parallel to the centerline perpendicular to the object's axis of rotation. However, when installing tilt sensors on irregularly shaped surfaces, it's difficult to maintain parallelism, making it challenging to accurately measure the change in boom tilt angle. Summary of the Invention

[0004] To facilitate the leveling and installation of tilt sensors on irregular surfaces and improve the detection accuracy of subsequent tilt sensors, this application provides a tilt sensor for mining applications.

[0005] The tilt sensor for mining applications provided in this application adopts the following technical solution:

[0006] The tilt sensor for mining includes a support base for detachable connection to the object being measured, a sensor body spaced apart on one side of the support base, a data transmission line connected to one side of the sensor body, a rotational leveling mechanism disposed between the sensor body and the support base for rotating the sensor body in both horizontal and vertical directions to keep the sensor body parallel to the center line of the object being measured, which is perpendicular to its axis of rotation, and a protection mechanism disposed above the rotating plate base for protecting the data transmission line and the sensor body.

[0007] By adopting the above technical solution, when the operator installs the tilt sensor on the irregular surface of the object being measured, the rotating plate is first detachably connected to the surface of the object. Then, the sensor body is rotated along the horizontal and vertical axes by a rotational leveling mechanism, so that the sensor body is parallel to the center line of the object's rotation axis. This ensures that the X-axis and Y-axis of the tilt sensor are parallel to the X-axis and Y-axis of the object being measured, respectively, thus leveling the sensor body. Next, the operator connects the data transmission line to the sensor body and external equipment, and the sensor body and data transmission line are protected by a protection mechanism, thus completing the installation of the tilt sensor. The tilt sensor installation is completed because the operator can quickly level the tilt sensor by using the rotational leveling mechanism to make it parallel to the center line of the object's rotation axis, allowing for accurate measurement of the tilt angle change. Furthermore, the harsh environment of the mine prevents dust from entering the sensor body, thus improving the stability of the tilt sensor's operation.

[0008] Optionally, the rotary leveling mechanism includes a support shaft fixed on the support base, a rotating plate rotatably sleeved on the side of the support shaft near the sensor body, an adjusting gear disposed between the rotating plate and the sensor body, and an adjusting worm gear disposed between the rotating plate and the support base.

[0009] It also includes a vertical leveling assembly disposed between the adjusting gear, the sensor body, and the rotating plate for driving the sensor body to rotate along the horizontal axis; a horizontal adjusting assembly disposed between the adjusting worm, the rotating plate, and the support for driving the rotating plate and the sensor body to rotate along the vertical axis; and a drive locking assembly disposed between the adjusting worm and the adjusting gear for driving the adjusting gear and the adjusting worm to rotate or lock.

[0010] By adopting the above technical solution, when the operator uses the rotary leveling mechanism to level the sensor body in the horizontal and vertical directions, firstly, the operator drives the adjusting worm gear to rotate via the drive locking component. Then, the adjusting worm gear, through the horizontal leveling component, drives the rotating plate to rotate along the vertical axis of the support shaft. The rotating plate then drives the vertical leveling component and the sensor body to rotate, thereby aligning the X-axis and Y-axis of the sensor body with the X-axis and Y-axis of the object being measured, respectively, in the same vertical plane. Next, the operator drives the adjusting gear to rotate via the drive locking component. Then, the adjusting gear, through the vertical leveling component, drives the sensor body to rotate along the horizontal axis perpendicular to the vertical axis of the support shaft, thus aligning the sensor... The X and Y axes of the sensor body are kept parallel to the horizontal planes of the X and Y axes of the object being measured, thus enabling leveling of the sensor body in both horizontal and vertical directions. The operator can simultaneously control the operation of both the horizontal and vertical leveling components via the drive locking assembly, facilitating quick leveling of irregular surfaces on the object being measured and installation of the tilt sensor. Furthermore, the drive locking assembly can lock the adjusting gear and worm gear, locking the sensor body's position after leveling to prevent it from shifting due to vibration or other factors, thereby further improving the stability and accuracy of the tilt sensor's detection.

[0011] Optionally, the vertical leveling assembly includes a support rod fixed on the side of the rotating plate near the sensor body, a telescopic rod with both ends hinged between the sensor body and the rotating plate, an adjusting screw rotatably connected to the side of the rotating plate near the sensor body, a moving block slidably connected to the side of the sensor body near the rotating plate along the length of the sensor body, and an adjusting sleeve with one end hinged to the side of the moving block near the adjusting screw.

[0012] The end of the support rod away from the rotating plate is hinged to the sensor body. The adjusting sleeve and the telescopic rod are located on both sides of the support rod. The adjusting gear is fixedly sleeved on the outside of the adjusting screw. The adjusting sleeve is threadedly connected to the adjusting screw.

[0013] By adopting the above technical solution, when the horizontal planes of the X and Y axes of the sensor body are kept parallel to the horizontal planes of the X and Y axes of the object being measured using the vertical leveling component, the operator first drives the adjusting gear to rotate by driving the locking component. The adjusting gear then drives the adjusting screw to rotate, which in turn drives the adjusting sleeve to move up and down. Simultaneously, the adjusting sleeve drives the moving block to move, which in turn drives the sensor body to rotate around the horizontal hinge axis of the support rod. Then, the telescopic rod is lengthened or shortened, thereby allowing the sensor body to rotate along the horizontal axis perpendicular to the vertical axis of the support rod. This ensures that the horizontal planes of the X and Y axes of the sensor body are kept parallel to the horizontal planes of the X and Y axes of the object being measured, achieving vertical leveling of the sensor body. The telescopic rod strengthens the support of the sensor body, making it less prone to lateral breakage at the connections between the sensor body and the support rod and the adjusting sleeve.

[0014] Optionally, the horizontal adjustment assembly includes a worm gear fixedly sleeved to the outside of the support shaft and a support block fixedly mounted on the side of the rotating plate near the support seat; the worm gear meshes with the adjusting worm, and the support block is rotatably connected to the adjusting worm.

[0015] By adopting the above technical solution, when the X-axis and Y-axis of the sensor body are aligned with the X-axis and Y-axis of the object being measured in the same vertical plane using the horizontal leveling component, the operator first drives the adjusting worm gear to rotate via the driving locking component. The adjusting worm gear, under the action of the support block, drives the rotating plate to rotate circumferentially along the worm wheel. Then, the rotating plate drives the vertical leveling component and the sensor body to rotate, thereby aligning the X-axis and Y-axis of the sensor body with the X-axis and Y-axis of the object being measured in the same vertical plane, achieving horizontal leveling of the sensor body. The adjusting worm gear and worm wheel are self-locking, locking the rotating plate and preventing the rotating plate and sensor body from becoming misaligned due to vibration or other factors, thus improving the stability of the sensor operation.

[0016] Optionally, the drive locking assembly includes a transmission rod rotatably connected to the rotating plate, a drive gear fixedly sleeved on the end of the transmission rod near the adjusting gear, a driven bevel gear fixedly sleeved on the end of the transmission rod away from the drive gear, a drive rod disposed in the adjusting worm, a spline fixedly disposed on the drive rod, a driving bevel gear fixedly sleeved on the drive rod, and a locking component disposed between the rotating plate and the drive rod for locking the drive rod.

[0017] The driving gear meshes with the adjusting gear, and the driven bevel gear meshes with the driving bevel gear. The driving rod can rotate within the adjusting worm and slide along the length of the adjusting worm. One end of the adjusting worm is also provided with a spline groove, and the spline can be inserted into the spline groove. When the spline is inserted into the spline groove, the driving bevel gear and the driven bevel gear separate from each other. When the driving bevel gear and the driven bevel gear mesh with each other, the spline is located outside the spline groove.

[0018] By adopting the above technical solution, when the adjusting gear is rotated by the drive locking assembly, the operator first moves the drive rod, which drives the active bevel gear and the driven bevel gear to mesh. Then, the operator rotates the drive rod, which in turn drives the active and driven bevel gears to rotate. The driven bevel gear then drives the transmission rod and the drive gear to rotate, which in turn drives the adjusting gear to rotate. The adjusting gear then drives the sensor body to rotate along the horizontal axis through the vertical leveling assembly. When the adjusting worm gear is rotated by the drive locking assembly, the operator first moves the drive rod, causing the drive rod to engage with the splined worm gear. Within the spline groove on the rod, the driving bevel gear and the driven bevel gear simultaneously separate. Then, the operator rotates the drive rod, which in turn drives the spline and the adjusting worm gear to rotate. The operator can simultaneously control the operation of the horizontal and vertical leveling components through the drive locking component, making the rotary leveling mechanism more compact. After the operator levels the sensor body, moving the drive rod causes the driving bevel gear and the driven bevel gear to mesh. By locking the drive rod through the locking component, the adjusting gear can be locked, preventing it from rotating due to vibration or other factors, thereby improving the sensor's detection accuracy.

[0019] Optionally, the locking component includes a locking block fixed on the side of the rotating plate near the support base and a locking screw threaded onto the locking block; the locking block has a locking hole, one end of the drive rod is inserted into the locking hole, and one end of the locking screw extends into the locking hole and is tightly fitted against the outer wall of the drive rod.

[0020] By adopting the above technical solution, when locking the drive rod through the locking component, the operator first rotates the locking screw so that the end of the locking screw presses against the outer wall of the drive rod, making it difficult for the drive rod to rotate or move along its length, thus locking the drive rod. Similarly, the operator loosens the locking screw so that the end of the locking screw separates from the outer wall of the drive rod, thus releasing the lock on the drive rod. The locking component not only improves the stability of the rotary leveling mechanism, but is also simple and convenient to operate.

[0021] Optionally, the spline may also have a chamfer on the side near the spline groove.

[0022] By adopting the above technical solution, the chamfer plays a positioning and guiding role when the spline is inserted into the spline groove, making it more convenient and faster for the drive rod to insert the spline into the spline groove.

[0023] Optionally, the protection mechanism includes a protective shell fixed on the support base, an operating door panel hinged to the protective shell, a buckle disposed between the protective shell and the operating door panel, and a snap-fit ​​component disposed between the protective shell and the support base for fixing the data transmission line close to one end of the sensor body.

[0024] By adopting the above technical solution, when the operator needs to adjust the sensor body, they can open the operating door by releasing the fastener, and then operate the rotary leveling mechanism located inside the protective shell. After the operator has finished adjusting, the operating door can be fixed by the fastener, thus protecting the sensor body and the rotary leveling mechanism. The fastener can also fix the end of the data transmission line close to the sensor body, making the connection between the data transmission line and the sensor body less likely to be pulled and broken, thereby improving the stability of the sensor body's operation.

[0025] Optionally, the snap-fit ​​component includes multiple snap rings fixed on the data transmission line, and the side wall of the protective shell has multiple snap grooves adapted to the snap rings, with the snap rings inserted into the snap grooves.

[0026] By adopting the above technical solution, when the end of the data transmission line located outside the protective shell is subjected to a tensile force, the retaining ring and retaining groove will block the tensile force, making the connection between the end of the data transmission line located in the protective shell and the sensor body less susceptible to the influence of tensile force, thereby making it less likely for the connection between the data transmission line and the sensor body to break.

[0027] Optionally, the operating door panel and the retaining ring are both covered with sealing gaskets along their respective circumferences.

[0028] By adopting the above technical solution, the environment around the mine is relatively harsh. The sealing gasket can improve the sealing between the operating door panel and the protective shell, and between the retaining ring and the retaining groove, so that impurities, dust, water and other substances are not easy to enter the protective shell and affect the sensor body.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. When installing an inclinometer on the irregular surface of the object being measured, the operator can quickly align the inclinometer with the center line of the object's rotation axis using a rotating leveling mechanism. This ensures the inclinometer is leveled and installed, allowing it to accurately measure the change in inclinometer angle. Simultaneously, the harsh environment of the mine provides protection for the sensor body and data transmission lines, preventing dust from entering the sensor and thus improving its operational stability.

[0031] 2. The drive locking component can not only control the operation of the horizontal leveling component and the vertical leveling component at the same time, making it easy for the staff to quickly level the irregular surface of the object being measured and install the tilt sensor, but also lock the adjusting gear and adjusting worm gear. That is, after the staff has leveled the sensor body, the position of the sensor body is locked, so that the sensor body is not easily deflected by vibration or other factors, thereby further improving the stability and accuracy of the tilt sensor detection.

[0032] 3. The horizontal adjustment component has a self-locking property, which can lock the rotating plate, making the rotating plate and the sensor body less susceptible to self-rotation misalignment due to vibration and other factors, thereby improving the stability of sensor operation;

[0033] 4. By driving the locking component, the operation of both the horizontal and vertical leveling components can be controlled simultaneously, making the rotary leveling mechanism more compact. After the operator levels the sensor body, the drive rod is moved to mesh the active and driven bevel gears. The drive rod is then locked by the locking component, which locks the adjusting gears, making them less susceptible to vibration and thus improving the sensor's detection accuracy.

[0034] 5. When the end of the data transmission line located outside the protective shell is subjected to tensile force, the retaining ring and retaining groove will block the tensile force, making the connection between the end of the data transmission line located outside the protective shell and the sensor body less susceptible to tensile force, thus making the connection between the data transmission line and the sensor body less prone to breakage.

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] This application discloses a tilt sensor for mining applications. (Refer to...) Figure 1 and Figure 2 The tilt sensor includes a support base 2 for detachable connection to the object being measured 1 via bolts. A sensor body 3 is spaced apart on one side of the support base 2, and a data transmission line 4 is connected to one side of the sensor body 3. A rotational leveling mechanism 5 is provided between the sensor body 3 and the support base 2. The rotational leveling mechanism 5 is used to rotate the sensor body 3 in both horizontal and vertical directions, keeping the center line of the sensor body 3 parallel to the center line of the rotation axis of the object being measured, which is perpendicular to the object 1. That is, the X-axis and Y-axis of the tilt sensor are parallel to the X-axis and Y-axis to be measured of the object 1, respectively. A protection mechanism 6 is also provided above the rotating plate 52, which protects the data transmission line 4 and the sensor body 3.

[0045] When installing the tilt sensor on the irregular surface of the object being measured (1), the operator first connects the rotating plate 52 to the surface of the object 1 with bolts. Then, the rotating leveling mechanism 5 drives the sensor body 3 to rotate along the horizontal and vertical axes, making the sensor body 3 parallel to the center line of the rotating axis of the object 1, which is perpendicular to it. That is, the X-axis and Y-axis of the tilt sensor are parallel to the X-axis and Y-axis of the object 1 to be measured, respectively. This leveling process ensures that the tilt sensor can accurately measure the tilt angle change of the object 1. Next, the operator connects the data transmission line 4 to the sensor body 3 and external equipment, and the protection mechanism 6 protects the sensor body 3 and the data transmission line 4. This completes the installation of the tilt sensor. In addition, the harsh environment around the mine allows the protection mechanism 6 to protect the sensor body 3 and the data transmission line 4, preventing dust from entering the sensor body 3 and thus improving the stability of the tilt sensor's operation.

[0046] Reference Figure 2 and Figure 3 The protection mechanism 6 includes a protective shell 61 fixed on the support base 2. The protective shell 61 has openings on both sides along its width. An operating door panel 62 is hinged to one of the openings of the protective shell 61. A buckle 63 is provided between the protective shell 61 and the operating door panel 62. A snap-fit ​​component 64 is provided between the protective shell 61 and the support base 2. The snap-fit ​​component 64 is used to fix the end of the data transmission line 4 near the sensor body 3. The snap-fit ​​component 64 includes multiple retaining rings fixed on the data transmission line 4. Multiple retaining grooves 611 adapted to the retaining rings are opened in the side wall of the protective shell 61, and the retaining rings are inserted into the retaining grooves 611. Sealing gaskets are laid along the circumference of both the operating door panel 62 and the retaining rings. Given the harsh environment around the mine, the sealing gaskets are used to improve the sealing between the operating door panel 62 and the protective shell 61, and between the retaining rings and the retaining grooves 611.

[0047] When the operator needs to adjust the sensor body 3, the operating door 62 can be opened by releasing the buckle 63, and then the rotary leveling mechanism 5 located inside the protective shell 61 can be operated. After the operator has finished adjusting, the operating door 62 can be fixed by the buckle 63, which can protect the sensor body 3 and the rotary leveling mechanism 5. When the end of the data transmission line 4 located outside the protective shell 61 is subjected to a pulling force, the retaining ring and the retaining groove 611 will block the pulling force, so that the connection between the end of the data transmission line 4 located in the protective shell 61 and the sensor body 3 is not easily affected by the pulling force, thereby making it less likely for the connection between the data transmission line 4 and the sensor body 3 to break, and improving the stability of the operation of the sensor body 3.

[0048] Reference Figure 4 and Figure 5The rotary leveling mechanism 5 includes a support shaft 51 fixed on the support base 2, the support shaft 51 being perpendicular to the support base 2, and a rotating plate 52 rotatably mounted on the side of the support shaft 51 closest to the sensor body 3. An adjusting gear 53 is provided between the rotating plate 52 and the sensor body 3. A vertical leveling assembly 54 is provided between the adjusting gear 53, the sensor body 3, and the rotating plate 52, and the vertical leveling assembly 54 is used to drive the sensor body 3 to rotate along a horizontal axis perpendicular to the support shaft 51. An adjusting worm gear 55 is provided between the rotating plate 52 and the support base 2. A horizontal adjustment assembly 56 is provided between the adjusting worm gear 55, the rotating plate 52, and the support base 2, and the horizontal adjustment assembly 56 is used to drive the rotating plate 52 and the sensor body 3 to rotate along a vertical axis. A drive locking component 57 is provided between the adjusting worm 55 and the adjusting gear 53. The drive locking component 57 is used to drive the adjusting gear 53 and the adjusting worm 55 to rotate or lock. That is, the operation of the horizontal leveling component and the vertical leveling component 54 can be controlled simultaneously by the drive locking component 57, which makes it easy for the staff to quickly level the irregular surface of the object being measured 1 and install the tilt sensor.

[0049] Reference Figure 4 and Figure 5 The vertical leveling assembly 54 includes a support rod 541 fixed to the side of the rotating plate 52 near the sensor body 3. The support rod 541 is perpendicular to the rotating plate 52, and the end of the support rod 541 away from the rotating plate 52 is hinged to the sensor body 3. A telescopic rod 542 is provided between the sensor body 3 and the rotating plate 52, and both ends of the telescopic rod 542 are hinged to the sensor body 3 and the rotating plate 52, respectively. An adjusting screw 543 is rotatably connected to the side of the rotating plate 52 near the sensor body 3. The adjusting screw 543 is perpendicular to the rotating plate 52, and an adjusting gear 53 is fixedly sleeved on the outside of the adjusting screw 543. A moving block 544 is provided on the side of the sensor body 3 near the rotating plate 52. The moving block 544 can be a T-shaped block or a dovetail block, etc. A moving groove 31 is opened below the sensor body 3, and the moving block 544 slides within the moving groove 31. An adjusting sleeve 545 is hinged to the side of the movable block 544 near the adjusting screw 543. The adjusting sleeve 545 is threadedly connected to the adjusting screw 543, and the adjusting sleeve 545 and the telescopic rod 542 are located on both sides of the support rod 541.

[0050] Reference Figure 5 and Figure 6 The horizontal adjustment assembly 56 includes a worm gear 561 fixedly sleeved to the outside of the support shaft 51, and the worm gear 561 meshes with the adjusting worm 55. Two support blocks 562 are fixedly provided on the side of the rotating plate 52 near the support base 2. The two support blocks 562 are located at both ends of the adjusting worm 55, and the support blocks 562 are rotatably connected to the adjusting worm 55.

[0051] Reference Figure 6 and Figure 7 The drive locking assembly 57 includes a transmission rod 571 rotatably connected to the rotating plate 52, the transmission rod 571 being perpendicular to the rotating plate 52; a drive gear 572 is fixedly sleeved on the end of the transmission rod 571 near the adjusting gear 53, and the drive gear 572 meshes with the adjusting gear 53. A driven bevel gear 573 is fixedly sleeved on the end of the transmission rod 571 away from the drive gear 572. A drive rod 574 is provided inside the adjusting worm gear 55, the drive rod 574 can rotate within the adjusting worm gear 55 and slide along the length direction of the adjusting worm gear 55; a knob 575 is also fixedly mounted on one end of the drive rod 574. A spline 576 is fixedly mounted on the drive rod 574, and a spline groove is also provided at one end of the adjusting worm gear 55, into which the spline 576 can be inserted. A chamfer is also provided on the side of the spline 576 near the spline groove; the chamfer serves as a positioning guide when the spline 576 is inserted into the spline groove, making it easier and faster for the drive rod 574 to insert the spline 576 into the spline groove. A drive bevel gear 577 is fixedly mounted on the drive rod 574, and a driven bevel gear 573 meshes with the drive bevel gear 577. When the spline 576 is inserted into the spline groove, the drive bevel gear 577 and the driven bevel gear 573 separate. When the drive bevel gear 577 and the driven bevel gear 573 mesh, the spline 576 is located outside the spline groove.

[0052] Reference Figure 6 and Figure 7 A locking component 578 is provided between the rotating plate 52 and the drive rod 574 to lock the drive rod 574. The locking component 578 includes a locking block 5781 fixed on the side of the rotating plate 52 near the support base 2. The locking block 5781 has a locking hole, and one end of the drive rod 574 is inserted into the locking hole. A locking screw 5782 is threaded onto the locking block 5781; one end of the locking screw 5782 extends into the locking hole and fits tightly against the outer wall of the drive rod 574.

[0053] When the operator uses the rotating leveling mechanism 5 to level the sensor body 3 in both horizontal and vertical directions, the operator first moves the drive rod 574 by turning the knob 575, causing the drive rod 574 to drive the spline 576 to insert into the spline groove on the adjusting worm 55. At the same time, the driving bevel gear 577 and the driven bevel gear 573 separate from each other. Then, the operator turns the knob 575, which drives the drive rod 574, spline 576 and adjusting worm 55 to rotate. Then, the adjusting worm 55, under the action of the support block 562, drives the rotating plate 52 to rotate around the worm wheel 561 for fine adjustment. Then, the rotating plate 52 drives the vertical leveling component 54 and the sensor body 3 to rotate, so that the X-axis and Y-axis of the sensor body 3 are in the same vertical plane as the X-axis and Y-axis of the object being measured 1, respectively, thus achieving the leveling of the sensor body 3 in the horizontal direction.

[0054] Next, the operator moves the drive rod 574 by turning knob 575. The drive rod 574 drives the driving bevel gear 577 and the driven bevel gear 573 to mesh with each other. At the same time, the spline 576 disengages from the spline groove on the adjusting worm gear 55. Then, the operator turns knob 575, which drives the drive rod 574, the driving bevel gear 577, and the driven bevel gear 573 to rotate. The driven bevel gear 573 then drives the transmission rod 571 and the drive gear 572 to rotate. The drive gear 572 then drives the adjusting gear 53 to rotate. The adjusting gear 53 then drives the adjusting screw 543 to rotate. The adjusting screw 543 then moves the adjusting sleeve 545 up and down. Simultaneously, the adjusting sleeve 545 drives the moving block 544 to move within the moving groove 31. The moving block 544 drives the sensor body 3 to rotate around the horizontal hinge axis of the support rod 541. Then, the telescopic rod 542 is stretched or shortened, thereby allowing the sensor body 3 to rotate along the horizontal axis perpendicular to the vertical axis of the support shaft 51. This keeps the horizontal planes of the X and Y axes of the sensor body 3 parallel to the horizontal planes of the X and Y axes of the object being measured 1, achieving vertical leveling of the sensor body 3. In summary, this ensures that the X and Y axes of the sensor body 3 remain parallel to the X and Y axes of the object being measured 1. After the staff levels the sensor body 3, the drive rod 574 is moved to engage the driving bevel gear 577 and the driven bevel gear 573. The locking screw 5782 is then rotated to press the end of the locking screw 5782 against the outer wall of the drive rod 574, thus locking the drive rod 574 and preventing it from rotating or moving along its length. At the same time, the adjusting gear 53 is locked, preventing it from rotating due to vibration. Furthermore, the adjusting worm 55 and worm wheel 561 have self-locking properties, which can lock the rotating plate 52, preventing the rotating plate 52 and the sensor body 3 from rotating and misaligning due to vibration, thereby improving the stability and detection accuracy of the sensor.

[0055] The implementation principle of a mine tilt sensor according to an embodiment of this application is as follows: When the operator installs the tilt sensor on the irregular surface of the object being measured 1, the rotating plate 52 is first connected to the surface of the object being measured 1 by bolts. Then, the drive rod 574 is moved by the knob 575, so that the drive rod 574 drives the spline 576 to be inserted into the spline groove on the adjusting worm 55. Then, the knob 575 is rotated, and the knob 575 can drive the adjusting worm 55 to rotate through the drive locking component 57. Then, the adjusting worm 55 drives the rotating plate 52 to rotate along the vertical axis of the support shaft 51 through the horizontal leveling component. The rotating plate 52 can drive the vertical leveling component 54 and the sensor body 3 to rotate, so that the X-axis and Y-axis of the sensor body 3 are in the same vertical plane as the X-axis and Y-axis to be measured of the object being measured 1, respectively.

[0056] Next, the operator moves the drive rod 574 via knob 575, causing the drive rod 574 to engage the driving bevel gear 577 with the driven bevel gear 573. Simultaneously, the spline 576 disengages from the spline groove on the adjusting worm gear 55. Then, knob 575 is rotated, which, through the drive locking assembly 57, drives the adjusting gear 53 to rotate. The adjusting gear 53 then, through the vertical leveling assembly 54, drives the sensor body 3 to rotate along the horizontal axis of the vertical support shaft 51. This ensures that the horizontal planes of the X and Y axes of the sensor body 3 are parallel to the horizontal planes of the measured object 1's X and Y axes, thus achieving leveling of the sensor body 3 in both horizontal and vertical directions, ensuring that the sensor body 3 is perpendicular to the axis of rotation of the measured object 1. With the center lines kept parallel, the operator then connects the data transmission line 4 to the sensor body 3 and external equipment. The sensor body 3 and data transmission line 4 are protected by the protection mechanism 6, thus completing the installation of the tilt sensor. When the operator installs the tilt sensor on the irregular surface of the object being measured 1, the rotational leveling mechanism 5 quickly aligns the tilt sensor with the center line perpendicular to the rotation axis of the object, ensuring the tilt sensor is level and allowing for accurate measurement of the tilt angle change of the object 1. Simultaneously, the harsh environment surrounding the mine allows the protection mechanism 6 to protect the sensor body 3 and data transmission line 4, preventing dust from easily entering the sensor body 3 and thus improving the stability of the tilt sensor's operation.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
