Description

Technical Field

[0001] This invention relates to the field of rod-type displacement sensor technology, specifically a rod-type displacement sensor based on support displacement monitoring and its usage method. Background Technology

[0002] A lever-type displacement sensor, also known as a lever displacement transmitter, is a linear displacement transmitter used to measure linear motion. It converts the linear distance traveled by an object into a 4-20mA current output or a 0-10V voltage output, which is then transmitted to a host computer. Based on the received signal, the host computer can monitor the object's current state in real time and control it, enabling automated operation in industrial production. Its ingenious structural design ensures convenient and reliable installation, while meticulous internal processing guarantees smooth and noiseless operation. Special laser engraving technology gives the product high linearity. It can be widely used in displacement and liquid level measurement and control in various industries such as petroleum, chemical, power, water treatment, metallurgy, papermaking, shipbuilding, and boilers. Its working principle is to convert the change in angular displacement into linear displacement using a winding wheel and a pull line (rope). The linear displacement is calculated based on the ratio of the angle change to the circumference of the winding wheel. For example, if the angular displacement parameter is 360 degrees corresponding to 0-10k, and the circumference of the winding wheel is 100mm, then the actual calculated linear displacement is 100mm corresponding to 0-10k, with a resolution of 10mm / k.

[0003] However, in the use of existing rod-type displacement sensors, the rod and the sensor cylinder are connected, resulting in friction between them. This friction can easily cause the runout tolerance of the rod to shift when it moves inside the sensor cylinder, affecting the movement accuracy of the connected object. Furthermore, the existing technology lacks monitoring and correction facilities for the runout tolerance of the rod during movement, leaving room for improvement. Summary of the Invention

Step S2: During the movement of the lever-type displacement sensor lever 3, the lever jump monitoring infrared sensor 51 works, emitting ranging infrared rays from four directions of the lever-type displacement sensor lever 3 cross section to the lever-type displacement sensor lever 3; Step S3: The controller of the lever-type displacement sensor lever 3 calculates the runout tolerance of the lever-type displacement sensor lever 3 during its movement based on the time difference between the ranging infrared light emitted and returned by the lever runout monitoring infrared sensor 51.

[0029] The working principle of this invention is as follows: The lever-type displacement sensor, also known as a lever displacement transmitter, is a linear displacement transmitter used to measure linear motion. It transmits the linear movement distance of an object into a 4-20mA current output or a 0-10V voltage output, which is then sent to a host computer. Based on the received signal, the host computer can monitor the current state of the object in real time and control it, achieving automated operation in industrial production. Its ingenious structural design ensures convenient and reliable installation; meticulous internal processing ensures stable and noiseless operation; and special laser engraving technology gives the product high linearity. It can be widely used in displacement and liquid level measurement and control in various industries such as petroleum, chemical, power, water treatment, metallurgy, papermaking, shipbuilding, and boilers. Its working principle is to convert the change in angular displacement into linear displacement using a winding wheel and a pull rope. The linear displacement is calculated based on the ratio of the angle change to the circumference of the winding wheel. For example, if the angular displacement parameter is 360 degrees corresponding to 0-10k, and the circumference of the winding wheel is 100mm, then the actual calculated linear displacement is 100mm corresponding to 0-10k, with a resolution of 10mm / k.

[0030] However, in the use of the existing rod-type displacement sensor 1, because the rod 3 of the rod-type displacement sensor is movably connected to the head 13 of the rod-type displacement sensor, there is friction between the rod 3 and the head 13. This friction can easily cause the runout tolerance of the rod 3 to deviate when it runs inside the head 13, affecting the movement accuracy of the connected object. Furthermore, the existing technology lacks monitoring and correction facilities for the runout tolerance of the rod 3 during movement, leaving room for improvement.

[0031] In this application, during the movement of the rod 3 of the rod displacement sensor, the rod runout monitoring mechanism 5 surrounding the outer cylinder 2 of the rod displacement sensor is used to monitor the displacement of the rod 3. The rod runout adjustment drive mechanism 8 drives the rod runout adjustment mechanism 7 to move and compress the rod 3 to change the position of the rod 3, thereby correcting the runout tolerance of the rod 3 and ensuring the motion accuracy of the object connected to the rod 3. During this process, the distance between the pull rod jump monitoring infrared sensor 51 and the pull rod displacement sensor 3 is measured by emitting ranging infrared rays. The distance deviation between the pull rod jump monitoring infrared sensor 51 and the pull rod displacement sensor 3 in four directions can be calculated. Then, the position of the pull rod displacement sensor 3 is adjusted by the pull rod jump adjustment mechanism 7 in four directions to ensure the movement accuracy of the pull rod displacement sensor 3 and the connected object.

[0032] This application stores lubricating oil inside the rod lubrication mechanism 4. During the movement of the rod-type displacement sensor rod 3, the lubricating oil inside the rod lubrication mechanism 4 will naturally drip onto the rod-type displacement sensor rod 3 and lubricate the rod sensor cylinder head 13 and the rod-type displacement sensor rod 3, thereby reducing the friction between the rod sensor cylinder head 13 and the rod-type displacement sensor rod 3 and reducing the influence of the runout tolerance of the rod-type displacement sensor rod 3.
