Description

Technical Field

[0001] This invention relates to the field of general mechanical equipment manufacturing technology, specifically to a speed measuring probe mounting gap adjustment device for a geared disc. Background Technology

[0002] The geared disc speed measuring device mainly consists of two parts: a geared disc and a speed measuring probe. The geared disc is fixed to the main shaft of the hydro-generator, and the speed measuring probe is fixed to the bottom of the air-water collection tank of the generator main shaft, flush with the geared disc and with a certain gap between them. During unit operation, the geared disc rotates with the main shaft. The speed measuring probe generates a speed pulse signal by scanning the evenly distributed teeth on the geared disc. This signal is then processed by the PLC and signal conversion device to output an analog value of the unit's speed. The geared disc speed measuring probe emits a pulse signal when it detects metal. However, due to the probe's detection range, if the metal is too far in front of the probe, it will not be able to detect it accurately; if it is too close, it may damage the probe. Therefore, controlling the gap between the speed measuring probe and the geared disc within a suitable range is crucial.

[0003] During the maintenance of the gear disc speed measuring device, when maintenance personnel adjust the gap between the speed measuring probe and the teeth, the probe often faces the concave part of the gear disc, making it impossible to directly adjust the gap between the speed measuring probe and the teeth. Furthermore, the existing gear disc probe bracket has poor adjustment capability and low degree of freedom of movement. Even when the gap is indirectly measured using tools such as feeler gauges and vernier calipers, the results are often significantly inaccurate due to the dual limitations of space conditions and the structure of the gear disc bracket. When the unit speed is not measured or cannot be accurately measured during the start-up test after the unit maintenance is completed, a lot of time and manpower are wasted, and the maintenance task is affected on schedule. In severe cases, the speed measuring probe may even be damaged, endangering the operation of the unit. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention provide a speed measuring probe mounting gap adjustment device for gear discs to quickly adjust the speed measuring probe mounting gap.

[0006] The toothed disc speed measuring probe mounting gap adjustment device of this embodiment includes:

[0007] The support assembly is L-shaped and includes a first support rod and a second support rod. The lengths of the first support rod and the second support rod are adjustable. One end of the first support rod is connected to the air-water collection tank of the generator main shaft. The extension direction of the second support rod is the same as the radial direction of the gear plate.

[0008] The measuring assembly includes a measuring base, a mounting plate, and a positioning plate. The measuring base is connected to the other end of the second support rod. The mounting plate is fixedly disposed on one side of the measuring base and is used to mount a speed measuring probe so that the extension direction of the speed measuring probe is the same as the radial direction of the gear disc. The positioning plate is an arc-shaped plate adapted to the size of the gear disc and is used to fit tightly against the gear disc and cover at least two gear teeth. The positioning plate is slidably mounted on the measuring base along the extension direction of the second support rod. The positioning plate is detachably connected to the measuring base. The measuring base is provided with a scale for displaying the distance between the speed measuring probe mounted on the mounting plate and the side of the positioning plate closest to the mounting plate.

[0009] In this embodiment of the invention, the speed probe mounting gap adjustment device for a geared disc can be adjusted so that the sum of the scale reading and the thickness of the positioning plate equals the required distance from the speed probe to the gear teeth. By adjusting the length of the second support rod, the positioning plate is tightly attached to the gear teeth. Removing the positioning plate reveals the desired distance between the speed probe and the gear teeth. This device features a simple structure. By using the positioning plate as a positioning reference, only the distance between the positioning plate and the speed probe, and the position of the measuring base relative to the geared disc, needs to be adjusted to quickly determine the position of the speed probe relative to the gear teeth. This allows for rapid adjustment of the mounting gap between the speed probe and the gear teeth, ensuring safe and efficient operation.

The driving bevel gear is coaxial and fixedly disposed at the end of the drive screw that extends into the groove. The driven bevel gear is coaxial and fixedly disposed on the driven screw. The driven bevel gear meshes with the driving bevel gear for transmission.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 6 As shown, the gear disc speed probe mounting gap adjustment device 100 of this embodiment includes a support component 1 and a measuring component 2.

[0033] The support assembly 1 is L-shaped and includes a first support rod 11 and a second support rod 12, both of which are adjustable in length. One end of the first support rod 11 is connected to the generator main shaft air-water injection tank (not shown in the figure), and the extension direction of the second support rod 12 is the same as the radial direction of the gear plate (not shown in the figure).

[0034] The measuring assembly 2 includes a measuring base 21, a mounting plate 22, and a positioning plate 23. The measuring base 21 is connected to the other end of the second support rod 12. The mounting plate 22 is fixedly disposed on one side of the measuring base 21 and is used to mount the speed measuring probe 4 so that the extension direction of the speed measuring probe 4 is the same as the radial direction of the gear disc. The positioning plate 23 is an arc-shaped plate adapted to the size of the gear disc and is used to fit tightly against the gear disc and cover at least two gear teeth. The positioning plate 23 is slidably mounted on the measuring base 21 along the extension direction of the second support rod 12, and the positioning plate 23 is detachably connected to the measuring base 21. The measuring base 21 is provided with a scale 24, which is used to display the distance between the speed measuring probe 4 mounted on the mounting plate 22 and the side of the positioning plate 23 closest to the mounting plate 22.

[0035] In use, the gear disc speed probe 4 mounting gap adjustment device 100 of this embodiment can adjust the position of the positioning plate 23 on the measuring base 21 so that the sum of the reading on the scale 24 and the thickness of the positioning plate 23 is equal to the distance from the speed probe 4 to the gear teeth to be set. By adjusting the length of the second support rod 12, the positioning plate 23 is tightly attached to the gear teeth of the gear disc. At this time, the positioning plate 23 is removed, and the distance from the speed probe 4 to the gear teeth is the distance to be set. The gear disc speed probe 4 mounting gap adjustment device 100 of this embodiment has a simple structure. By using the positioning plate 23 as the positioning reference, only the distance between the positioning plate 23 and the speed probe 4 and the position of the measuring base 21 relative to the gear disc need to be adjusted to quickly determine the position of the speed probe 4 relative to the gear teeth, so as to quickly adjust the mounting gap between the speed probe 4 and the gear teeth. The operation is safe and efficient.

[0036] Optionally, there is a set distance between the mounting plate 22 and the end of the measuring base 21 so that after the speed probe 4 is installed on the mounting plate 22, the probe end of the speed probe 4 is aligned with the end of the measuring base 21, so as to facilitate measurement and adjustment.

[0037] Optionally, multiple positioning plates 23 can be manufactured, and the thickness of the multiple positioning plates 23 is different, so that one can be selected according to the set distance between the detection probe and the wheel teeth during use.

[0038] Optionally, multiple positioning plates 23 can be machined, and the corresponding curvatures of the multiple positioning plates 23 are different, so that one that matches the toothed disc can be selected according to the diameter of the toothed disc during use.

[0039] In some embodiments, a slider 25 is slidably mounted on the measuring base 21 along the direction of the second support rod 12, and the positioning plate 23 is inserted into the slider 25.

[0040] By setting the slider 25, it is convenient to connect the positioning plate 23 with the measuring base 21 and to adjust the positioning plate 23 relative to the measuring base 21.

[0041] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a T-shaped groove 211 is provided on the measuring base 21 and extends through the side of the measuring base 21. A driving component 3 for driving the slider 25 to move relative to the measuring base 21 is provided in the groove 211.

[0042] By setting the drive component 3, it is easy to accurately control the movement of the slider 25 and ensure that the slider 25 can be fixed in the corresponding position after moving relative to the measuring base 21.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the drive assembly 3 includes a drive screw 31, a driven screw 32, a driving bevel gear 33, and a driven bevel gear 34. The drive screw 31 is rotatably connected to the measuring base 21 and one end extends into the slide groove 211. The driven screw 32 is rotatably disposed in the slide groove 211 and extends along the extension direction of the slide groove 211. The driven screw 32 is threadedly connected to the slider 25. The driving bevel gear 33 is coaxial and fixedly disposed at one end of the drive screw 31 that extends into the slide groove 211. The driven bevel gear 34 is coaxial and fixedly disposed on the driven screw 32. The driven bevel gear 34 meshes with the driving bevel gear 33 for transmission.

[0044] Rotating the drive screw 31 causes the active bevel gear 33 to rotate. The driven bevel gear 34, through meshing with the active bevel gear 33, drives the driven screw 32 to rotate. The driven screw 32 then drives the slider 25 to move along the axial direction of the driven screw 32, thereby adjusting the position of the positioning plate 23.

[0045] Optionally, a drive wheel is fixedly installed on one end of the drive screw 31 located outside the measuring base 21.

[0046] Optionally, the two ends of the driven screw 32 are rotatably connected to the inner wall of the slide groove 211 via bearings.

[0047] Optionally, a bearing is coaxially provided on at least one side of the measuring base 21 on the drive screw 31. The bearing is used to fix the position of the drive screw 31 and ensure the meshing transmission between the driving bevel gear 33 and the driven bevel gear 34 while ensuring that the drive screw 31 is rotatably connected to the measuring base 21.

[0048] In some embodiments, such as Figure 5As shown, the slider 25 is provided with a first slot 251, the extension direction of the first slot 251 is the same as the extension direction of the first support rod 11, and the positioning plate 23 is connected with an L-shaped connecting plate 26. The connecting plate 26 includes a plug-in plate segment 261 and a connecting plate segment 262. The plug-in plate segment 261 is used to plug into the first slot 251, and the other end of the connecting plate segment 262 is connected to the positioning plate 23.

[0049] By setting the first slot 251, it is easy to fix the positioning plate 23, ensuring the relative distance between the positioning plate 23 and the mounting plate 22, thereby making the installation gap between the speed measuring probe 4 and the wheel teeth more accurate.

[0050] In some embodiments, both the plug-in plate segment 261 and the connecting plate segment 262 are magnetic. The plug-in plate segment 261 is adsorbed into the first slot 251, and the connecting plate segment 262 is adsorbed onto the surface of the slider 25, so as to facilitate the installation and fixation of the positioning plate 23.

[0051] In some embodiments, such as Figure 5 As shown, a second slot 252 is provided on the slider 25 corresponding to the first slot 251. The second slot 252 is connected to the first slot 251 and the extension direction of the second slot 252 is perpendicular to the extension direction of the first slot 251. A limiting block 27 is provided on the slider 25 corresponding to the second slot 252. The limiting block 27 is cam-shaped and is used to stop and cooperate with the connecting plate segment 262 in the extension direction of the first slot 251.

[0052] By setting a limiting block 27, the limiting block 27 is engaged with the connecting plate segment 262 on the outside of the second slot 252 to ensure that the position of the connecting plate segment 262 is fixed, thereby facilitating the fixing of the position of the positioning plate 23.

[0053] Optionally, the depth of the second slot 252 is equal to the thickness of the connecting plate segment 262.

[0054] In some embodiments, such as Figure 5 As shown, a top support spring 28 is provided in the second slot 252. One end of the top support spring 28 is fixedly connected to the second slot 252, and the other end of the top support spring 28 is used to press against the connecting plate segment 262.

[0055] By setting the top support spring 28, on the one hand, when the limiting block 27 blocks the connecting plate segment 262, the top support spring 28 can ensure that the connecting plate segment 262 is always in close contact with the limiting block 27. On the other hand, when the positioning plate 23 is removed, the top support spring 28 can push the plug-in plate segment 261 out of the first slot 251 a part, making it easier to remove the positioning plate 23.

[0056] Optionally, a hidden groove is provided in the second slot 252, and a top support spring 28 is provided in the hidden groove. One end of the top support spring 28 is fixedly connected to the bottom of the hidden groove, and the other end extends out of the hidden groove to support the side of the connecting plate segment 262.

[0057] In some embodiments, such as Figure 6 As shown, the plug-in plate segment 261 and the connecting plate segment 262 are rotatably connected.

[0058] The plug-in plate segment 261 and the connecting plate segment 262 are rotatably connected. After adjusting the distance between the speed probe 4 and the gear teeth through the positioning plate 23 and removing the positioning plate 23, the plug-in plate segment 261 and the connecting plate segment 262 can be rotated, and the plug-in plate segment 261 can be reinserted into the first slot 251. The connecting plate segment 262 is fixed by the limiting block 27, so that the positioning plate 23 and the slider 25 are connected together. When adjusting the distance between the speed probe 4 and the gear teeth again, it can be quickly retrieved, avoiding the loss of the positioning plate 23 and the search for the positioning plate 23, and improving the efficiency of adjusting the gap between the speed probe 4 and the gear teeth.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the first support rod 11 includes a first sleeve section 111 and a first insert rod section 112, both with rectangular cross sections that are inserted together. The other end of the first sleeve section 111 is connected to the generator main shaft air supply water tank, and the other end of the first insert rod section 112 is fixedly connected to the second support rod 12. A first adjusting screw 113 is rotatably provided on the first sleeve section 111, and a connecting lug 114 that is fixedly connected to the second support rod 12 is threaded onto the first adjusting screw 113.

[0060] With a simple structure and easy processing, the first insertion rod section 112 is driven to move relative to the first sleeve section 111 through the threaded connection of the first adjusting screw 113 and the connecting lug 114, and the adjustment is precise.

[0061] Optionally, a first adjusting wheel is provided at the other end of the first adjusting screw 113.

[0062] In some embodiments, a locking component is provided on the first adjusting screw 113 corresponding to the connecting lug 114. The locking component is used to stop and engage with the connecting lug 114 in the axial direction of the first adjusting screw 113.

[0063] A locking component is provided to facilitate fixing the length of the first support rod 11, making the length adjustment of the first support rod 11 more accurate.

[0064] Optionally, the locking assembly includes two positioning nuts 115, which are threaded onto the first adjusting screw 113 and located on both sides of the connecting lug 114. The two positioning nuts 115 are used to engage with the connecting lug 114 in the axial direction of the first adjusting screw 113 to fix the threaded connection position between the connecting lug 114 and the first adjusting screw 113.

[0065] In some embodiments, such as Figure 1 and Figure 2 As shown, the second support rod 12 includes a second sleeve section 121 and a second insertion rod section 122, both with rectangular cross sections that are inserted together. The side wall of the second sleeve section 121 is connected to the first support rod 11. The other end of the second insertion rod section 122 is fixedly connected to the measuring base 21. The end of the second insertion rod section 122 located inside the second sleeve section 121 is rotatably provided with a second adjusting screw 123. The second adjusting screw 123 passes through the second sleeve section 121 and is threadedly connected to the second sleeve section 121.

[0066] With a simple structure and easy processing, the second insertion rod section 122 is driven to move relative to the second sleeve section 121 through the threaded connection of the second adjusting screw 123 and the second sleeve section 121, and the adjustment is precise.

[0067] Optionally, an adjusting nut is provided on the end face of the second sleeve section 121 corresponding to the second adjusting screw 123. The adjusting nut is threadedly connected to the second adjusting screw 123 and is fixedly connected to the second sleeve section 121.

[0068] Optionally, a second adjusting wheel is provided at the other end of the second adjusting screw 123.
