Description

Technical Field

[0001] This utility model relates to the field of inclinometer technology, and in particular to an inclinometer based on a magnetic grating sensor. Background Technology

[0002] In the fields of industrial manufacturing, construction engineering, and automation equipment, accurate measurement of the tilt angle of objects is crucial. Traditional tilt measurement equipment has many limitations, such as complex mechanical structures leading to cumbersome installation and debugging, and measurement accuracy being significantly affected by environmental factors, making it difficult to meet the high-precision measurement needs in diverse scenarios. With technological advancements, tiltmeters based on magnetic grating sensors are gradually being widely used due to their advantages such as high precision and non-contact measurement.

[0003] However, in existing inclinometers based on magnetic grating sensors, the magnetic grating scale and the measuring structure are mostly fixedly connected. When the magnetic grating scale is damaged or needs to be replaced to adapt to different measurement needs, the disassembly process is extremely inconvenient, consuming a lot of time and manpower, and may also affect the continuity and efficiency of the measurement work. In addition, in practical applications, the measurement range of existing inclinometers based on magnetic grating sensors is often limited by the fixed installation position of the magnetic grating sensor and the magnetic grating scale, and cannot flexibly adapt to measurement scenarios at different heights.

The lifting assembly includes four fixing blocks: two fixing blocks are welded to the upper side of the vertical plate, and the other two are welded to the lower side of the vertical plate. A motor is bolted to the outer side of the upper fixing block; the output shaft of the motor passes through one fixing block and is connected to a drive wheel via a coupling; the end of the drive wheel away from the motor is rotatably connected to one fixing block; a driven wheel is rotatably connected between the two lower fixing blocks; the drive wheel and the driven wheel are connected by a transmission belt; a connecting plate is fixed to one side of the transmission belt; and a magnetic grating sensor is installed on one side of the connecting plate.

[0006] As a further description of the above technical solution:

[0007] The connecting assembly includes a mounting strip fixed to one side of the upright plate. The mounting strip has a placement groove, in which the magnetic ruler is inserted. Insert rods are slidably connected to the upper and lower walls of the mounting strip. Insert holes are provided at the upper and lower ends of the magnetic ruler. One end of each of the two insert rods extends into the placement groove and is inserted into the two insertion holes respectively. The other end of each of the two insert rods extends to the outside of the mounting strip and is fixed with a pull block. Springs are sleeved on the outside of each of the two insert rods.

[0008] As a further description of the above technical solution:

[0009] The two ends of the spring are welded to the side of the pull block and the outside of the mounting strip, respectively.

[0010] As a further description of the above technical solution:

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the magnetic grating sensor is raised and lowered along the magnetic grating ruler by activating the lifting assembly. When the plane on which the device is located is tilted, gravity causes the magnetic grating sensor to be displaced in the direction perpendicular to the magnetic grating ruler, which causes the magnetic field signal of the magnetic grating ruler sensed by the magnetic grating sensor to change. The magnetic grating sensor converts this signal into an electrical signal and then into a digital signal after processing. The vertical displacement is calculated by analyzing the digital signal. Combined with the lifting and lowering position information of the magnetic grating sensor along the magnetic grating ruler, the tilt angle is obtained by using trigonometric function relationships, thereby realizing the measurement of the tilt degree. It can flexibly adapt to measurement scenarios of different heights.

[0028] Reference Figures 1-4An embodiment of this utility model includes a base plate 1, with a vertical plate 2 bolted to the top surface of the base plate 1.

Two fixing blocks 3 are welded to the upper side of the vertical plate 2, and the other two fixing blocks 3 are welded to the lower side of the vertical plate 2. A motor 4 is bolted to the outer side of the upper fixing block 3. The output shaft of the motor 4 passes through a fixing block 3 and is connected to a drive wheel 5 through a coupling. The end of the drive wheel 5 away from the motor 4 is rotatably connected to a fixing block 3. A driven wheel 6 is rotatably connected between the two lower fixing blocks 3. The drive wheel 5 and the driven wheel 6 are connected by a transmission belt 7. A connecting plate 8 is fixed to one side of the transmission belt 7, and a magnetic grating sensor 9 is installed on one side of the connecting plate 8.

[0029] The connecting assembly includes a mounting strip 13, which is fixed to one side of the upright plate 2. A placement groove 19 is provided on the mounting strip 13, and a magnetic ruler 14 is inserted into the placement groove 19. Insert rods 16 are slidably connected through the upper and lower walls of the mounting strip 13. Insertion holes are provided at both the upper and lower ends of the magnetic ruler 14. One end of each insert rod 16 extends into the placement groove 19 and is inserted into the two insertion holes respectively. The other end of each insert rod 16 extends to the outside of the mounting strip 13 and is fixedly connected to a pull block 15. A spring 17 is fitted around the outside of each insert rod 16. The two ends of the spring 17 are welded to the side of the pull block 15 and the outside of the mounting strip 13 respectively. By adjusting the connecting assembly, the magnetic ruler 14 can be removed from the placement groove 19. The operation is simple. It saves time and effort and helps improve the continuity and efficiency of measurement work. The pull block 15 is provided with anti-slip texture. The connecting plate 8 is fixed to the side of the vertical plate 2 with a connecting rod 10. One end of the connecting rod 10 is fixed to a T-shaped slider 11. The side of the vertical plate 2 is provided with a T-shaped groove 12. The T-shaped slider 11 is slidably connected in the T-shaped groove 12. The output shaft of the motor 4 is provided with a support seat. The bottom surface of the base plate 1 is rotatably connected to a universal wheel 18 with a locking mechanism. The side of the vertical plate 2 and next to the mounting strip 13 is provided with a scale line. The structure technology of the magnetic grating sensor 9 and the magnetic grating ruler 14 is already very mature and has been widely used. It will not be described in detail here. At the same time, this application does not protect the specific structure of the magnetic grating sensor 9 and the magnetic grating ruler 14.

[0030] Working principle: By starting the motor 4, the motor 4 drives the drive wheel 5 to rotate, which in turn causes the transmission belt 7 to rotate. The rotation of the transmission belt 7 causes the connecting plate 8 to rise and fall. The rising and falling of the connecting plate 8 causes the magnetic grating sensor 9 to rise and fall, causing the magnetic grating sensor 9 to rise and fall along the magnetic grating ruler 14. When the plane on which the device is located is tilted, gravity causes the magnetic grating sensor 9 to be displaced in the direction perpendicular to the magnetic grating ruler 14. This causes the magnetic field signal of the magnetic grating ruler 14 sensed by the magnetic grating sensor 9 to change. The magnetic grating sensor 9 converts this signal into an electrical signal and then processes it into a digital signal. By analyzing the digital signal, the vertical displacement is calculated. Combined with the rising and falling position information of the magnetic grating sensor 9 along the magnetic grating ruler 14, the tilt angle is obtained using trigonometric functions, thereby realizing the measurement of the tilt. It can flexibly adapt to measurement scenarios of different heights.

[0031] By pulling the pull block 15, the pull block 15 moves the insertion rod 16, causing the insertion rod 16 to move out of the insertion hole on the magnetic scale 14, and the magnetic scale 14 can be removed from the placement slot 19. The operation is simple, time-saving and labor-saving, which helps to improve the continuity and efficiency of measurement work.
