Description

Technical Field

[0001] This utility model relates to the field of indicator needle adjustment technology, and more specifically, to a three-dimensional adjustment indicator device. Background Technology

[0002] In the prior art, long-term vibration causes the position of the indicator needle on the tailwater disc valve to shift, which makes it impossible to effectively open or close the tailwater disc valve according to the indicated data.

[0003] In the switching movement of a volute disc valve, the indicator needle can serve as an indication and calibration device. During the switching process of the volute disc valve, the valve disc and valve stem of the volute disc valve will drive the indicator needle to move up and down. However, during operation, vibration will cause the indicator needle to deviate, making it impossible to effectively calibrate based on the indicated data.

[0004] In the main shaft seal of a hydroelectric power station, the sealing ring is subjected to water pressure impact, and rust occurs due to years of use. The indicator needle is set to indicate the amount of wear; however, during use, the indicator needle will move around, making it impossible to accurately display the amount of wear.

[0019] In some possible implementations, in order to effectively achieve measurement in three dimensions, an indicator block is provided on the screw block for use with scale lines, and the indicator block is located above the fixing base.

[0020] In some possible implementations, in order to effectively realize the transmission connection between two adjacent sets of transfer platforms (transfer platform one and transfer platform two, transfer platform two and transfer platform three), a transfer component is provided between transfer platform one and transfer platform two, and between transfer platform two and transfer platform three, respectively.

[0021] In some possible implementations, in order to effectively adapt the present invention to the requirements of the field environment through the setting of the adapter, the adapter includes a connecting plate connected to the mounting platform or sliding block, and a connecting block installed at the bottom of the connecting plate and connected to the sliding block or mounting platform; the bottom or side of the connecting block is installed on the sliding block or mounting platform.

[0022] In some possible implementations, in order to effectively avoid the bottom of the bolt when the adapter and the sliding block are bolted together, an avoidance groove is provided on the mounting platform and at the bottom of the sliding block. The avoidance groove is connected to the sliding groove and is located at the bottom of the sliding groove.

[0023] In some possible implementations, the first, second, and third adapter platforms and the indicator needle are each made of a metal material with corrosion-resistant properties.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The present invention will now be described in detail.

[0039] like Figures 1-8 As shown:

[0040] A three-dimensional adjustment indicator includes a first transfer platform 1, a second transfer platform 2 mounted on the first transfer platform 1 and slidably fitted thereto, a third transfer platform 3 mounted on the second transfer platform 2 and slidably fitted thereto, and an indicator needle 4 mounted on the third transfer platform 3 and pulsatorically connected to the third transfer platform 3; the indicator needle 4 is used in conjunction with an indicator sign.

[0041] The first adapter platform 1 includes an X-axis motion component for mounting the second adapter platform 2 and for controlling the movement of the second adapter platform 2 along the X-axis direction;

[0042] The second adapter platform 2 includes a Y-axis motion component for mounting the third adapter platform 3 and for controlling the movement of the third adapter platform 3 along the Y-axis direction;

[0043] The adapter platform 3 includes a Z-axis motion component for the indicator needle 4 and for controlling the movement of the indicator needle 4 along the Z-axis.

[0044] Compared with the prior art, this utility model can automatically adjust in three dimensions (X-axis, Y-axis, and Z-axis), avoiding the problems of low efficiency and large accumulated errors that require multiple steps when adjusting with bolts.

[0045] The first adapter platform 1 controls the second adapter platform 2 and the third adapter platform 3 to move along the X-axis, thereby causing the indicator needle 4 mounted on the third adapter platform 3 to move along the X-axis.

[0046] The second adapter platform 2 controls the third adapter platform 3 to move along the Y-axis, thereby causing the indicator needle 4 mounted on the third adapter platform 3 to move along the Y-axis.

[0047] The transfer platform 3 controls the movement of the indicator needle 4 mounted on the transfer platform 3 along the Y-axis; thereby enabling the indicator needle 4 to return to its original position through adjustment in the three-dimensional direction after it has shifted, vibrated or deviated.

[0048] In some possible implementations, to ensure the good versatility of the transfer platform 1, transfer platform 2, and transfer platform 3 in this invention, modular assembly is used to greatly improve work efficiency and utilization. For this purpose, the X-axis motion component, Y-axis motion component, and Z-axis motion component are designed and manufactured with the same structure, including a mounting platform 11 with a sliding groove, a screw 12 mounted on the mounting platform 11 and rotatably engaged with it, and a slider 13 fitted around the outside of the screw 12 and drivingly engaged with it. The slider 13 is installed in a limiting groove 141 and slidably engaged with it.

[0049] Specifically, a bearing is provided on the fixed seat 15, and the screw 12 is fitted inside the bearing and connected to the inner ring of the bearing; the outer side of the bearing is connected to the fixed seat 15, thereby realizing the rotational engagement between the screw 12 and the fixed seat 15.

[0050] The screw 12 in the X-axis motion assembly is set along the X-axis direction; the screw 12 in the Y-axis motion assembly is set along the Y-axis direction; the screw 12 in the Z-axis motion assembly is set along the Z-axis direction; thus, independent control of axial displacement and radial compensation is achieved, and multi-dimensional parameter synchronous adjustment can be completed in a single operation.

[0051] The X-axis motion component, Y-axis motion component, and Z-axis motion component respectively convert the screw drive into linear motion of the slider 13 in the X-axis, Y-axis, or Z-axis direction, resulting in good adjustment accuracy. The indicator needle 4 does not need to be removed during the entire adjustment process; the adjustment is simple and convenient.

[0052] In some possible implementations, in order to ensure that the slider 13 can only move linearly along the axis of the screw 12 and not rotate, a pressure block 14 is installed on the mounting platform 11 on the side of the slider 13 away from the screw 12, and a U-shaped limiting groove 141 is formed between the pressure block 14 and the mounting platform 11; the limiting groove 141 is connected to the sliding groove.

[0053] The slider 13 includes a screw block 132 that is fitted on the outside of the screw 12 and is in transmission cooperation with the screw 12, and a sliding block 131 that is connected to the screw block 132 and is in sliding cooperation with the slide groove and the limiting groove 141;

[0054] The side of the sliding block 131 away from the screw block 132 is located in the limiting groove 141 and slides in cooperation with the limiting groove 141; the bottom of the pressure block 14 will effectively restrict the rotation of the sliding block 131 around the axis of the screw 12 when the sliding block 131 moves along the long direction of the screw 12.

[0055] In some possible implementations, a fixing seat 15 is provided on the mounting platform 11 for mounting the screw 12 and located on the side of the slide groove away from the limiting groove 141; the fixing seat 15 is provided with an L-shaped groove 151 with an L-shaped cross section on the side near the slider 13, and a sliding cavity is formed between the L-shaped groove 151 and the pressure block 14, and the sliding cavity is connected to the slide groove; the screw block 132 is located in the L-shaped groove 151; a scale line 152 is provided on the fixing seat 15 along the axial direction of the screw 12; by setting the scale line 152, the adjustment of the movement of the slider 13 in three dimensions can be effectively realized, so that the adjustment meets the requirements.

[0056] In some possible implementations, in order to effectively achieve measurement in three dimensions, an indicator block 16 is provided on the screw block 132 to cooperate with the scale line 152. The indicator block 16 is located above the fixed base 15 and is slidably engaged with the fixed base 15. By turning the screw 12, the screw block 132, the sliding block 131, and the indicator block 16 are moved along the axial direction of the screw 12. The indicator block 16, in cooperation with the scale line 152, will achieve precise control of the distance the slider 13 moves along the axis of the screw 12.

[0057] In some possible implementations, in order to effectively realize the transmission connection between two adjacent sets of transfer platforms (transfer platform 1 and transfer platform 2, transfer platform 2 and transfer platform 3), a transfer member 5 is provided between transfer platform 1 and transfer platform 2, and between transfer platform 2 and transfer platform 3, respectively.

[0058] In some possible implementations, in order to effectively adapt the present invention to the requirements of the field environment through the setting of the adapter 5, the adapter 5 includes a connecting plate 51 connected to the mounting platform 11 or the sliding block 131, and a connecting block 52 installed at the bottom of the connecting plate 51 and connected to the sliding block 131 or the mounting platform 11; the bottom or side of the connecting block 52 is installed on the sliding block 131 or the mounting platform 11.

[0059] The connecting block 52 is a plate-shaped or column-shaped structure. When it is a plate-shaped structure, its side is mounted on the sliding block 131 and stacked with the sliding block 131, and is connected to the sliding block 131 by bolts.

[0060] When it is a columnar structure, the end of the columnar structure away from the connecting plate 51 will act on the sliding block 131, and the connection with the sliding block 131 will be achieved by bolts;

[0061] By connecting the connecting block 52 to the sliding block 131 at different positions, this device can be used in different environmental spaces.

[0062] like Figure 1 As shown: the sliding block 131 in the first adapter platform 1 is connected to the side of the connecting block 52, and the corresponding connecting plate 51 is installed at the bottom of the mounting platform 11 in the second adapter platform 2; the sliding block 131 in the second adapter platform 2 is connected to another set of connecting blocks 52, and the connecting plate 51 of this set of adapters 5 is connected to the mounting platform 11 of the third adapter platform 3; the indicator needle 4 is installed on the sliding block 131 of the third adapter platform 3; the sliding blocks 131 of the second adapter platform 2 and the third adapter platform 3 are both located on the side away from the first adapter platform 1.

[0063] In this case, adapter platform 1 is in a fixed state. The screw 12 on adapter platform 1 rotates, causing the sliding block 131 on adapter platform 1 to move along the X-axis. This causes adapter platform 2, adapter platform 3, and the indicator needle 4 to move along the X-axis, achieving adjustment of the indicator needle 4 in the X-axis direction. Since the mounting platform 11 in adapter platform 2 is connected to adapter platform 1, the mounting platform 11 will remain fixed and not move. When the screw 12 on adapter platform 2 rotates, the adapter... The sliding block 131 on platform 2 will move along the Y-axis, thereby driving the adapter platform 3 and the indicator needle 4 to move along the Y-axis. The sliding block 131 in adapter platform 2 is connected to the mounting platform 11 of adapter platform 3 through the adapter 5. The screw 12 on adapter platform 3 rotates, and the sliding block 131 on adapter platform 3 will move along the Z-axis, thereby driving the indicator needle 4 to move in the Z-axis direction. Finally, the adjustment of the indicator needle 4 is achieved in the X, Y, and Z axes.

[0064] like Figure 6 , Figure 7 As shown: Adapter platform 1 and adapter platform 2 are connected by two sets of adapters 5, which are connected by two sets of connecting plates 51, and two sets of connecting blocks 52 are respectively connected to two sets of sliding blocks 131; adapter platform 2 and adapter platform 3 are connected by one set of adapters 5, whose connecting plate 51 is connected to the mounting platform 11 of the adapter platform, and whose connecting block 52 is connected to the sliding block 131 of the adapter platform 3; the indicator needle 4 is connected to the mounting platform 11 of the adapter platform 3 via one set of adapters 5, whose connecting plate 51 is connected to the mounting platform 11 of the adapter platform 3; the sliding blocks 131 of adapter platform 2 and adapter platform 3 are both located on the side closer to adapter platform 1;

[0065] In this situation, adapter platform 1 is in a fixed state. The screw 12 on adapter platform 1 rotates, causing the sliding block 131 on adapter platform 1 to move along the X-axis, thereby moving adapter platform 2, adapter platform 3, and indicator needle 4 along the X-axis, realizing the adjustment of indicator needle 4 in the X-axis direction. Since the mounting platform 11 in adapter platform 2 is connected to adapter platform 1, the sliding block 131 in adapter platform 2 will be in a fixed state and will not move. The screw 12 on adapter platform 2 rotates. At this time, the mounting platform 11 on the second adapter platform 2 will move along the Y-axis, thereby driving the third adapter platform 3 and the indicator needle 4 to move along the Y-axis; the mounting platform 11 in the second adapter platform 2 is connected to the sliding block 131 of the third adapter platform 3 through the adapter 5, and the screw 12 on the third adapter platform 3 will rotate, causing the mounting platform 11 on the third adapter platform 3 to move along the Z-axis, thereby driving the indicator needle 4 to move in the Z-axis; finally, the adjustment of the indicator needle 4 is achieved in the X, Y, and Z axes.

[0066] like Figure 6 As shown, an adapter 5 is installed on the mounting platform 11 of the adapter platform 3. The adapter 5 has a connecting plate with a plate-like structure and its length is set along the X-axis. The side of the connecting plate is connected to the indicator needle 4, so that the length of the indicator needle 4 is also set along the X-axis.

[0067] like Figure 7 As shown, by installing the adapter 5 on the mounting platform 11 of the adapter platform 3, wherein the connecting plate of the adapter 5 is a columnar structure, and the side of the connecting plate away from the adapter platform 3 serves as the mounting surface for the installation of the indicator needle 4, the longitudinal direction of the indicator needle 4 can be set along the Z-axis or Y-axis direction.

[0068] like Figure 8 As shown, the screw 12 in adapter platform 1 is perpendicular to the plane of the mounting platform 11 of adapter platform 2; the sliding block 131 of adapter platform 1 is connected to the mounting platform 11 of adapter platform 2 through adapter 5. The connecting plate in adapter 5 is a plate-shaped structure and is connected to the sliding block 131 of adapter platform 1 through its side; the screw 12 in adapter platform 2 is perpendicular to the plane of the mounting platform 11 of adapter platform 3; the sliding block 131 of adapter platform 2 is connected to the mounting platform 11 of adapter platform 3 through adapter 5. The connecting plate in adapter 5 is a plate-shaped structure and is connected to the sliding block 131 of adapter platform 2 through its side; the indicator needle 4 will be directly installed on the sliding block 131 of adapter platform 3.

[0069] pass Figure 1 , Figure 6 , Figure 7 , Figure 8The four structural designs shown in this utility model enable it to be applicable to installation needs in different environments and spaces.

[0070] In some possible implementations, in order to effectively avoid the bottom of the bolt when the adapter 5 and the sliding block 131 are bolted together, an avoidance groove 101 is provided on the mounting platform 11 and at the bottom of the sliding block 131.

[0071] Furthermore, in order to ensure that the device has good corrosion and rust prevention performance, the first adapter platform 1, the second adapter platform 2, the third adapter platform 3, and the indicator needle 4 are made of metal materials with corrosion resistance, such as stainless steel and titanium alloy.

[0072] When using 316L stainless steel, a 20-50μm chromium plating layer is applied to its surface, achieving a hardness of HV 900-1100 and significantly improving corrosion resistance. This solution is particularly economical and suitable for use in adjusting wear-resistant threaded areas, particularly in hydropower station water supply systems and general industrial drive shafts.

[0073] When duplex stainless steel (such as 2205 stainless steel and 2507 stainless steel) is used, due to its chromium content of 22%-25% and molybdenum content of 3%-4%, it has good resistance to chloride ion corrosion (such as seawater and salt spray), pitting corrosion and stress corrosion cracking. Its yield strength is >450MPa and its hardness is HRC 28-32, which is better than ordinary austenitic stainless steel. It is suitable for harsh environments such as screws in hydropower stations, high-pressure valves, and drive shafts in marine engineering.

[0074] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
