Technical Field

[0001] This utility model relates to the field of steam turbine maintenance technology, specifically a professional disassembly and assembly tool for steam turbine shaft vibration. Background Technology

[0002] During the operation of large steam turbines, shaft vibration sensors (such as eddy current probes) are usually installed in the bearing housing or journal to monitor the rotor's operating status in real time. These probes are exposed to high temperature and high vibration environments for extended periods and require periodic disassembly, maintenance, or replacement.

[0003] However, commonly used tools such as adjustable wrenches and Allen wrenches have the following problems when disassembling shaft vibration probes and their mounting components: inaccurate positioning, which can easily cause sensor position displacement and affect vibration measurement accuracy; mismatched tools, which can lead to difficulties in disassembly and assembly, and are time-consuming and labor-intensive; and high safety risks, which can easily damage the sensor body or thread structure and cause potential equipment malfunctions. Therefore, we propose a professional disassembly and assembly tool for turbine shaft vibration. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses the cooperation of a slide rail and a slider to prevent the clamping block from shifting position. The clamping block is further supported by a three-point V-groove and engages with the slider, effectively preventing positional shift of the shaft vibration probe after installation and removal, ensuring vibration measurement accuracy. The threaded rod rotates within the fixed plate, adjusting the slider's position within the slide rail. This allows the clamping block to be adjusted according to the probe's width, making it compatible with various shaft vibration probe models and different installation conditions. No multiple sets of specialized tools are required. Furthermore, the clamping block allows for faster installation and removal of the shaft vibration probe; simply rotating the threaded rod in both directions moves the slider within the slide rail, enabling quick installation and removal of the shaft vibration probe.

[0015] 2. This utility model uses a handwheel to drive the lead screw to rotate within the internal thread of the tool body, and the lead screw drives the transmission block to move back and forth within the guide rail, thereby achieving the purpose of adjusting the position of the fixed plate. At the same time, during the sliding process, the transmission block synchronously drives the indicator block to slide on the scale. By observing the position of the indicator block on the scale, it is convenient for the staff to refer to the displacement when disassembling and assembling the probe, thus improving the reset accuracy of the component.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, a professional disassembly and assembly tool for turbine shaft vibration includes a tool body 1. A fixed plate 2 is provided at the left end of the tool body 1. A clamping assembly 3 for holding a shaft vibration probe is provided inside the fixed plate 2. An adjustment assembly 4 is provided between the fixed plate 2 and the tool body 1. The tool body 1 can extend and retract the fixed plate 2 through the adjustment assembly 4. The clamping assembly 3 includes two sets of slide rails 31 symmetrically opened on the outer wall of the fixed plate 2. A slider 32 is slidably connected inside the slide rails 31. A component is fixedly connected to the outer surface of the slider 32. The clamping block 33 has a V-shaped groove on one side of each clamping block 33. A threaded rod 34 is fixedly connected to the slider 32 through a bearing. The threaded rod 34 is threadedly connected to the fixed plate 2. A slide groove 35 is provided on the inner wall of the slide rail 31. A spring 36 is fixedly connected to the inner wall of the slide groove 35. A locking block 37 is fixedly connected to the other end of the spring 36. The locking block 37 is slidably connected to the slide groove 35. A locking groove 38 is provided on the surface of the slider 32 corresponding to the outer end of the locking block 37. The locking block 37 is slidably connected to the locking groove 38.

[0025] In practice, the shaft vibration probe is first attached to the two sets of clamping blocks 33. Then, the threaded rod 34 is rotated, causing it to rotate within the fixed plate 2 and push the slider 32 to slide within the slide rail 31. This causes the slider 32 to synchronously drive the two sets of clamping blocks 33 to clamp the shaft vibration probe. At this time, the engaging groove 38 on the slider 32 moves to align with the engaging block 37. Then, under the restoring force of the spring 36, the engaging block 37 returns to its original position within the slide groove 35 and engages with the engaging groove 38, thereby achieving the purpose of clamping the shaft vibration probe. Then, by reversing the threaded rod 34, the clamping blocks 33 are released from clamping the shaft vibration probe, thus achieving the purpose of quick assembly and disassembly.

[0026] As a technical optimization of this utility model, the tool body 1 is a T-shaped rigid structure design, which is used to support the various functional components as a whole. The tool body 1 is also made of high-strength aluminum alloy or stainless steel.

[0027] In practice, this can increase the overall strength of the tool body 1 and extend the service life of the entire tool, making the entire tool less prone to damage.

[0028] As a technical optimization of this utility model, the adjustment component 4 includes a guide rail 41 opened in the tool body 1, a transmission block 42 slidably connected in the guide rail 41, the outer end of the transmission block 42 being fixedly connected to the outer wall of the fixed plate 2, a lead screw 43 being fixedly connected to the inner end of the transmission block 42 through a bearing, the lead screw 43 being threadedly connected to the tool body 1, a handwheel 44 being fixedly connected to the outer end of the lead screw 43, a guide groove 45 being opened on the top of the tool body 1, the guide groove 45 being connected to the guide rail 41, an indicator block 46 being fixedly connected to the surface of the transmission block 42 in the guide groove 45, and the guide groove 45 and the indicator block 46 being slidably connected.

[0029] In practice, the handwheel 44 drives the lead screw 43 to rotate within the tool body 1, and the lead screw 43 drives the transmission block 42 to move back and forth within the guide rail 41, thereby achieving the purpose of adjusting the position of the fixed plate 2. At the same time, during the sliding process, the transmission block 42 synchronously drives the indicator block 46 to slide on the scale 47. By observing the position of the indicator block 46 on the scale 47, it is convenient for the staff to refer to the displacement when disassembling and assembling the probe, thus improving the component reset accuracy.

[0030] As a technical optimization of this utility model, a scale 47 is fixedly connected to the surface of the tool body 1 around the guide groove 45. The scale 47 is in contact with the indicator block 46, and the indicator block 46 slides back and forth linearly on the scale 47.

[0031] In practice, by observing the position of the indicator block 46 after the transmission block 42 moves on the scale 47 and stops, and combining this with the scale 47, the displacement amount referenced by the staff when disassembling and assembling the probe can be obtained, thereby improving the component reset accuracy.

[0032] As a technical optimization of this utility model, the transmission block 42 is designed in a rectangular shape, and the guide rail 41 is provided with a through hole adapted to the transmission block 42.

[0033] In practice, the guide rail 41 and the transmission block 42 can be fully fitted together, thereby ensuring the stability of the transmission block 42 when it slides back and forth in the guide rail 41.
