Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for positioning and installing monitoring probes, and in particular to a novel positioning and installation device for a steam turbine monitoring probe. Background Technology

[0002] As is well known, in the operation monitoring of steam turbines, the accurate positioning of monitoring probes (such as displacement sensors and temperature sensors) is crucial for equipment condition monitoring. In existing technologies, probe positioning typically relies on positioning groove structures machined onto the steam turbine body. Specifically, the probe is fixed by inserting it into the positioning groove, requiring a specific fit clearance (typically 0.01-0.05 mm) between the positioning groove and the probe to ensure the precise distance between the probe and the ranging disk (or the monitored target).

[0003] However, this positioning method requires extremely high precision during processing, which leads to high production costs. Furthermore, during installation, it requires multiple adjustments to the probe position and repeated measurement of the gap using tools such as feeler gauges and dial indicators, which is time-consuming and labor-intensive. It also demands a high level of technical skill from the operators, affecting installation efficiency and thus making it impractical. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a novel turbine monitoring probe positioning device that can quickly locate the installation position of the monitoring probe, reduce the requirements for probe installation accuracy, lower costs, and improve installation efficiency, thereby enhancing its practicality.

The inner end of the position adjustment component is in close contact with the support block. The top of the support block is connected to the support frame. A first through-hole is provided at the front end of the support frame, through which the monitoring probe passes. The support frame is fixed to the monitoring probe by a fixing component. Mounting and fixing components are provided on the outer wall of the base box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves fine adjustment of the probe position through position adjustment components (such as lead screws and support rods), eliminating the need for ultra-high precision machining, thus significantly reducing production costs. Furthermore, this utility model can quickly and accurately position the probe by linearly adjusting the position adjustment components (such as rotating the lead screw to push the support block) by simply measuring the parameters of the required fixed position of the probe, improving installation efficiency by more than 50% and reducing the dependence on the operator's technical skills. In addition, the fixing components adopt threaded engagement (friction block + nut) to double-lock the monitoring probe, preventing probe displacement caused by vibration during operation and ensuring long-term monitoring accuracy, thereby reducing costs and improving installation efficiency, thus enhancing practicality.
