Description
Technical Field
[0001] This utility model relates to the field of boiler expansion monitoring technology, specifically to a mounting bracket for a laser displacement sensor used for boiler expansion monitoring. Background Technology
[0002] As power plants shift from extensive to intensive management of generator equipment, data records of thermal expansion of equipment such as pipes and headers are also being managed. This data is helpful in understanding the causes of stress in the equipment. In order to accurately determine whether various pipes, headers, and containers are obstructed, whether the distribution is uniform, and whether they expand as required when heated, it is necessary to install expansion indicators at specific locations on the equipment.
[0003] For example, patent application CN202220264481.7, with an authorization announcement date of 20220816, describes an online monitoring system for boiler expansion displacement based on laser displacement sensors. This system includes a three-dimensional displacement monitoring component, a fixed support, a connecting rod, and a scale monitoring device. The connecting rod is horizontal, with its left and right ends perpendicularly connected to the fixed support and the measuring point on the boiler, respectively. The three-dimensional displacement monitoring component includes three laser displacement sensors, each positioned perpendicularly to one of the three ends of the fixed support. The laser displacement sensors are connected to a signal receiving device via an analog-to-digital converter, and the signal receiving device is connected to a computer terminal. Three scale monitoring devices are provided, each positioned corresponding to the monitoring position of the three laser displacement sensors. Each scale monitoring device includes a base, a support rod, a cross slide rail, and a scale.

[0039] This embodiment further defines the features of Embodiment 1. A rotating rod 23 is bolted to the center of one side of the magnetic turntable 17. A rotating handle 24 is bolted to one end of the rotating rod 23. The operator rotates the rotating handle 24, causing the rotating rod 23 to rotate. The rotating rod 23 passes through the threaded sleeve 15 and the support base 16, and then connects to the center of the magnetic turntable 17. Therefore, the rotation of the rotating rod 23 directly drives the magnetic turntable 17 to rotate. The mounting assembly 4 includes a support base 16. The magnetic turntable 17 is mounted on one end of the support base 16 via bearings. Four bolts are bolted to the outer wall of one side of the support base 16. The four slide rods 14 are arranged in a circular array. One end of each slide rod 14 is fixed to the support base 16, and the other end is slidably inserted into the four insertion slots 10 of the fixed cylinder seat 9. This structure provides stable guidance for the linear movement of the mounting assembly 4, preventing it from rotating or shaking and ensuring smooth and precise movement. A threaded sleeve 15 is integrally formed at the center of one end of the support base 16. The threaded sleeve 15 is interconnected with the support base 16, and the rotating rod 23 passes through the support base 16 and the threaded sleeve 15. The lead screw assembly 3 includes a fixed cylinder seat 9. One end of the fixed cylinder seat 9 has four insertion slots 10 arranged in a circular array, and the four slide rods 14 slide into the four insertion slots 10 respectively. The threaded sleeve 15 is slidably inserted into the four insertion slots 10. A rectangular groove 11 is provided at the center of one end of the fixed sleeve 9. The rectangular groove 11 provides space and limits for the movement of the threaded sleeve 15 within the fixed sleeve 9. The threaded sleeve 15 is slidably inserted into the rectangular groove 11.

It forms a threaded pair with the threaded sleeve 15 integrally formed on the support base 16. When the threaded rod 12 rotates, it drives the threaded sleeve 15 to move the entire mounting assembly 4 linearly along the axis of the threaded rod 12. Rod 12 is threadedly connected to threaded sleeve 15. One end of fixed cylinder seat 9 is integrally formed with flange seat 6. Flange seat 6 serves as the installation base for the entire support and is fixed to a solid foundation near the boiler by bolts. Fixed cylinder seat 9 and flange seat 6 are integrally formed to form the main support structure of the support. A groove 7 is provided at the center of one end of flange seat 6, and a through slot 13 is provided at one end of threaded rod 12. Rotating rod 23 passes through through slot 13, and one end of threaded rod 12 extends into the groove 7. A rotating handle 8 is bolted to one end of threaded rod 12. The operator turns the rotating handle 8 to directly drive the threaded rod 12 connected to it to rotate.
[0040] Working principle: The bracket assembly 2 is bolted into the center of the outer wall of one side of the reflector box 1 via the flange seat 6, forming a stable installation base. The fixing cylinder 9 of the lead screw assembly 3 is connected to the reflector box 1 via the flange seat 6. A groove 7 at one end of the fixing cylinder 9 accommodates part of the adjustment mechanism. The support seat 16 of the mounting assembly 4 is connected to the lead screw assembly 3 via a threaded sleeve 15 and sliding rods 14. The four sliding rods 14 are slidably inserted into the four insertion slots 10 of the fixing cylinder 9, providing linear guidance. The threaded sleeves 15 are slidably inserted into the rectangular grooves 11 of the fixing cylinder 9, ensuring movement stability. The magnetic turntable 17 of the adjustment assembly 5 is mounted on one end of the support seat 16 via bearings and can be rotated for adjustment. The laser displacement sensor is mounted via the clamp assembly 22. Specifically, the sensor body is placed inside the housing 28 of the clamp assembly 22, between two clamping plates 30. Turning the handle 35 drives the bidirectional lead screw 32 to rotate. Since the threads at both ends of the bidirectional lead screw 32 are in opposite directions, the two clamping plates 30 move synchronously towards each other within the slide groove 29, clamping the sensor via the rubber block 31. The mounting shell 25 of the clamp assembly 22 is threaded onto the outside of the adjusting lead screw 20 through the threaded hole 26. A connecting rod 33 is slidably inserted into one end of the mounting shell 25. The extension length of the connecting rod 33 can be adjusted by selecting different threaded grooves 34 and fixing it with a limiting screw 27. In this process, the limiting screw 27 is loosened, the connecting rod 33 is slid to the desired position, and then the limiting screw 27 is tightened so that its end inserts into the threaded groove 34 to achieve locking. After the sensor is installed, multi-stage adjustments are made using the bracket assembly 2, lead screw assembly 3, mounting assembly 4, and adjustment assembly 5 to ensure that the laser beam is accurately aligned with the target point of the reflector box 1. The adjustment sequence is usually from coarse adjustment to fine adjustment. Specifically: when coarsely adjusting the distance, the rotary handle 8 can be rotated to drive the threaded rod 12 to rotate. Since the threaded rod 12 is threadedly connected to the threaded sleeve 15, and the threaded sleeve 15 is restricted to move within the rectangular groove 11, the rotation of the threaded rod 12 is converted into linear movement of the mounting assembly 4. When coarsely adjusting the angle, the rotary handle 24 can be rotated to drive the rotating rod 23 to rotate. The rotating rod 23 is bolted to the magnetic turntable 17, so the magnetic turntable 17 rotates on the support base 16. Since the mounting base 18 and the clamp assembly 22 are both mounted on the support base 16, the adjustment sequence is as follows: On the magnetic turntable 17, the entire sensor can rotate 360° to easily align with monitoring targets in different directions. The magnetic design of the magnetic turntable 17 allows for quick positioning and temporary fixation. For fine-tuning the position, rotating each knob 21 drives the adjusting screw 20 to rotate. Since the adjusting screw 20 is threadedly connected to the threaded hole 26 of the mounting housing 25, the mounting housing 25 slides in the mounting groove 19, causing the clamp assembly 22 and the sensor to move independently in three mutually angular directions, achieving fine adjustment of the spatial position. For fine-tuning the length, the insertion depth of the plug rod 33 in the mounting housing 25 can be adjusted, different threaded grooves 34 can be selected and fixed with the limiting screw 27, and the extension length of the sensor can be finely adjusted to further optimize the optical path alignment.During boiler operation, the boiler expands due to heat, and the position of the reflector box 1 may change slightly. The laser displacement sensor calculates the expansion by monitoring the displacement of the reflector box 1. The adjustable support allows for quick alignment after initial installation and adaptability to changes during long-term monitoring. The rubber block 31 of the clamp assembly 22 buffers boiler vibration and prevents the sensor from loosening. All adjustment parts have self-locking or mechanical locking functions to ensure the support remains stable in a vibrating environment. Boiler expansion causing monitoring deviations can be fine-tuned on-site using the knob 21 or the rotating handle 24 without disassembling the support, improving monitoring continuity and efficiency. The threaded rod 12 of the lead screw assembly 3 and the slide rod 14 of the mounting assembly 4 are made of rigid materials to resist high-temperature deformation. The rotation adjustment of the magnetic turntable 17 is simple and facilitates periodic calibration.

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.
