Abstract
Description
[Technical Field]
[0001] The present invention relates to a level measuring device for measuring the level of a base plate support seat for installing a base plate of a hydraulic machine such as a vertical pump of a pumping and drainage facility or a hydraulic generator, and a method for adjusting and installing the base plate support seat using the same. [Background technology]
[0002] Conventionally, when installing hydraulic machinery such as vertical pumps in vertical piping in water treatment facilities such as pumping and drainage facilities, sewage treatment facilities, factories, and drainage facilities, the hydraulic machinery is usually installed by fixing the base plate to a base plate support seat installed on the foundation. In this case, in order to accurately install the hydraulic machinery in the specified installation space, a high degree of horizontality is required for the upper mounting surface of the base plate support seat. Therefore, this type of base plate support seat must be installed on the foundation with the mounting surface accurately adjusted to be horizontal.
[0003] In Patent Document 1, when installing a base plate for installing a pump on a base plate support seat, the base plate is installed so that its upper surface is horizontal from its tilted state, and the gap that occurs between this base plate and the base plate support seat, which serves as the foundation, is filled with an embedding material made of resin, and the base plate and base plate support seat are fixed with mounting bolts, thereby attempting to install the base plate while ensuring horizontality relative to the base plate support seat. After the base plate has been adjusted to its horizontal position, it is fixed to the foundation (base plate support) with anchor bolts or the like, and pumps are installed on the mounting surface of this base plate and fixed with bolts or the like.
[0004] A spirit level is generally used to measure the horizontality of a base plate support seat placed on a foundation. Figure 5 shows a plan view of an example of measuring the horizontality of a base plate support seat using a spirit level. An opening 2 is provided in the installation floor 1, which is the foundation on which the pump is installed, for inserting the pump and piping. A base plate support seat 3 for mounting the pump is placed around the opening 2, and the horizontality of the mounting surface of this base plate support seat 3 is measured.
[0005] When measuring the levelness, in the plan view of Figure 6, first, the straight edge 4 is placed on the top surface of the base plate receiving seat 3 so that it spans the center of the opening 2, for example, in the vertical direction, and then the spirit level 5 is placed in the center of this straight edge 4. Then, while visually checking the position of the air bubble in this spirit level 5 from outside, the levelness in the vertical direction in Figure 6 is measured.
[0006] Next, the straight edge 4 is placed across the horizontal direction, which is perpendicular to the vertical direction in Figure 6, and the horizontal level is measured by visually checking the air bubble in the level 5 at the center of the straight edge 4 from the outside in the same way as for the vertical direction. The order of these measurements in the up-down and left-right directions may be reversed, or the orientation may be shifted from up-down and left-right, but in any case, the measurement work is performed at least twice to measure the horizontality in the orthogonal directions in which the orientation of the base plate support seat 3 is different, and the horizontality of this base plate support seat 3 is adjusted. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-196450 Summary of the Invention [Problem to be solved by the invention]
[0008] However, when measuring the level of base plate support seat 3 using the conventional measurement procedure shown in Figure 6, it is necessary to visually check bubble level 5 placed at the center of straight edge 4 that is suspended over the center of opening 2. However, as the pump or the like becomes larger and the diameter of opening 2 becomes larger, the distance from the visual position on the outer periphery of opening 2 to level 5 becomes longer, making it difficult to see from the outside and making it even more difficult to confirm the exact position of the bubble. Therefore, as the diameter of opening 2 becomes larger, the accuracy of the measurement procedure is likely to decrease.
[0009] In addition, as the diameter of the opening 2 increases, the straight edge 4 spanning the opening 2 also becomes longer, making it more difficult to handle. Moreover, measurements must be taken in at least two directions, the up-down direction and the left-right direction in Figure 5, and the straight edge 4 must be replaced each time and its orientation and position must be adjusted multiple times, which increases the number of work steps and makes the work even more complicated.
[0010] In this way, when measuring the levelness in two separate steps, for example, when adjusting the levelness of the base plate support seat 3 using an adjustment method such as that described in Patent Document 1, the levelness in the vertical and horizontal directions of the base plate support seat 3 when viewed from above is measured and adjusted separately, making it difficult to adjust the levelness in all four directions simultaneously. For these reasons, there is a demand for the development of a level measurement device that can measure the level in all four directions of the mounting surface of the base plate support seat 3 at once, particularly when installing a large-diameter pump, and that can simultaneously adjust the level of the base plate support seat 3 based on the measurement results.
[0011] The present invention has been made in consideration of the above circumstances, and aims to provide a method for easily and accurately measuring the level of a base plate support seat when installing hydraulic machinery such as large vertical pumps for lifting and discharging water, hydroelectric generators, etc. [Means for solving the problem]
[0012] The device for measuring the level of a base plate support seat for installing a hydraulic machine of the present invention is a device for measuring the level of a base plate support seat having an opening and on which a base plate of a hydraulic machine is installed, and comprises a plurality of straight edges arranged at intervals around the circumferential direction of the base plate support seat, a plurality of digital levels placed at approximately the center of the upper surface of each of the straight edges to measure the level of the base plate support seat via the straight edges, a computer that collects data on the level of the base plate support seat from each of the digital levels, and a monitor that displays the level of the base plate support seat from the computer.
[0013] By placing each straight edge on the base plate seat and collecting the level measured by the digital level on each straight edge into a computer and then displaying it on a monitor, the level of the base plate seat in each direction can be checked via the monitor without having to directly check the level on the base plate seat. This elimination of the need to directly check the digital level makes the level measurement process easier, and even for large-diameter openings, the digital level can be easily installed and checked, and the level of the base plate in each direction can be accurately adjusted while visually checking the level on the monitor.
[0014] In the device for measuring the level of a base plate support for installing a hydraulic machine according to the present invention, it is preferable that four straight edges and four digital levels are provided.
[0015] In this case, the four straight edges should be arranged so that their length directions are perpendicular to the four directions of the water flow direction of the hydraulic machine on the base plate support and directions perpendicular to this water flow direction.
[0016] By placing the straight edge in the direction of the water flow of the hydraulic machine, it is possible to adjust the level in four directions based on the water flow side of the base plate support seat, enabling highly accurate measurement of the level of the base plate support seat.As a result, when installing the hydraulic machine on the base plate support seat, the water flow direction can be kept horizontal and the hydraulic machine can be installed with high precision.
[0017] In the apparatus for measuring the level of a base plate support for installing a hydraulic machine according to the present invention, the computer may cause the monitor to display the measured values of each of the plurality of digital levels. By checking the monitor, you can see the measurements of all the digital levels at once, making your work easier.
[0018] In the device for measuring the level of a base plate support for installing hydraulic machinery of the present invention, the computer may have a function of displaying a warning on the monitor when the level of the base plate support is greater than a predetermined reference value.
[0019] When reading the level numerically, a warning display prevents workers from misreading the measurement value and allows them to accurately check the level. Also, by checking the warning display while working, workers can simplify their work and complete the process from measuring to adjusting the level in a short amount of time.
[0020] In the apparatus for measuring the level of a base plate support for installing a hydraulic machine according to the present invention, it is desirable that the digital level has a communication function for wirelessly transmitting the measured level to the computer.
[0021] By wirelessly transmitting the measurement results of the digital level to a computer via the communication function, there is no need to run connecting cables, making work easier and safer.
[0022] The method for installing a base plate support for installing hydraulic machinery of the present invention comprises a base plate support on which a base plate of a hydraulic machinery is to be installed, a plurality of straightedges, a plurality of digital levels placed on the straightedges, a computer that collects levelness data from the digital levels, and a monitor that can display the levelness, and involves placing the straightedge with the digital levels placed on the base plate support seat, and adjusting the levelness of the base plate support seat while displaying on the monitor the levelness measurements collected by the computer from the digital levels.
[0023] According to this base plate support seat installation method, a straight edge and digital level are placed in predetermined positions, and the level of the base plate support seat can be checked through a monitor, making it easy to visually check the level of the base plate support seat through a monitor connected to a computer, even if the opening is large in diameter, and the level can be adjusted to install the base plate support seat with high precision. This allows hydraulic machinery such as pumps and motors connected to these pumps, or hydraulic turbines and generators connected to these turbines, to be installed accurately while ensuring levelness. [Effects of the Invention]
[0024] According to the present invention, the adjustment of the horizontality of the base plate support seat is made easy, so that the base plate support seat can be easily installed while ensuring a high level of horizontality.In addition, in a specified piping space such as vertical piping, the hydraulic machine can be accurately attached to the base plate support seat, allowing the functionality of the hydraulic machine to be fully utilized.

[Figure 6] FIG. 10 is a plan view illustrating a conventional method for measuring the horizontality of a base plate receiving seat. DETAILED DESCRIPTION OF THE INVENTION
[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a level measuring device for a base plate support for installing a hydraulic machine and a method for adjusting and installing the base plate support of the present invention will be described below with reference to the drawings. (Structure of level measurement device) The level measurement device 10 in this embodiment is a device for measuring the level of a base plate support 12 on which a vertical shaft axial flow pump (hereinafter simply referred to as a pump) 11, which is an example of hydraulic machinery, is installed, and as shown in Figure 1, it is equipped with an instrument consisting of four straight edges 13, four digital levels 14, a personal computer (hereinafter simply referred to as a computer) 15, and a monitor 16.
[0027] The base plate support 12 for installing the pump 11 is attached to a foundation (concrete) 20, which is constructed using concrete or other materials with a predetermined levelness ensured, and has an opening hole 21 formed in a vertically penetrating manner.
[0028] Base plate receiving seat 12 has an annular support portion 18 for supporting pump 11 formed integrally at the center of flat plate portion 17, and an opening 19 is formed inside support portion 18 in a vertically penetrating manner. Upper surface 18a of support portion 18 is formed flat. With base plate receiving seat 12 placed on foundation 20, the flatness of upper surface 18a of support portion 18 is measured by levelness measuring device 10, and the base plate receiving seat 12 is attached to foundation 20 while this flatness is adjusted.
[0029] In this example, opening 19 is formed with a diameter of approximately φ1500 mm. Pump 11 is provided with pump body 25, suction pipe 26 extending vertically, and discharge pipe 27 bent at a nearly right angle and extending horizontally, the vertical portion of discharge pipe 27 passing from opening 19 through opening hole 21 in foundation 20, pump body 25 is placed on support part 18, and discharge pipe 27 is placed horizontally. The pump 11 is also provided with a base plate 33 that is fixed to the support portion 18 of the base plate receiving seat 12 in a resting state. Reference numeral 28 denotes fixing holes for fixing the base plate receiving seat 12 to anchor bolts 29 embedded in the foundation 20. Reference numeral 30 denotes base plate mounting holes through which bolts (not shown) for fixing the base plate 33 of the pump 11 are inserted, and a plurality of such holes are formed at intervals around the circumference of the support portion 18.
[0030] In this embodiment, when measuring the level of the base plate support seat 12, the straight edge 13 is placed on the upper surface 18a of the support portion 18 of the base plate support seat 12, near the opening 19. A common commercially available product can be used as the straight edge 13, and its length is set as desired depending on the diameter of the opening 19 and the required level accuracy. In this case, the longer the straight edge 13, the greater the distance between its ends, which makes it possible to measure level over a wide range using the digital level 14 placed in the center of the straight edge 13.
[0031] The straight edges 13 are arranged so that their length directions are perpendicular to the discharge direction of the pump 11 on the base plate support seat 12, i.e., the extension direction of the discharge pipe 27 (the direction indicated by arrow X in FIG. 2), and the direction perpendicular to that. In other words, two straight edges 13 are arranged before and after the discharge direction in directions perpendicular to the discharge direction, and two straight edges 13 are arranged on both sides of the direction perpendicular to the discharge direction in directions perpendicular to that direction. Therefore, the four straight edges 13 are arranged at 90° intervals around the circumferential direction of the base plate support seat 12, and two straight edges are arranged parallel to each other.
[0032] In other words, the four straight edges 13 are arranged at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions, respectively, relative to the center S of the opening 19 of the base plate receiving seat 12 in Figure 1, and in a direction perpendicular to the radial direction of the opening 19.
[0033] The four digital levels 14 are placed at approximately the center of the top surfaces of the four straight edges 13. These digital levels 14 have a resolution that allows measurement of horizontality to at least 1 / 1000 mm, and these digital levels 14 measure the horizontality of the base plate receiving seat 12 (the horizontality of the top surfaces 18a of the support portions 18) via the straight edges 13.
[0034] Furthermore, the digital level 14 has a wireless communication function with the computer 15, and the level of the base plate 12 measured via this communication function is transmitted to the computer 15. Because this communication function is wireless, the work of running cables as with wired systems is unnecessary, and it becomes possible to check the level from a greater distance than with wired systems. Examples of wireless communication include WiFi and Bluetooth (registered trademark).
[0035] The computer 15 displays the measured value of the level sent from the digital level 14 on the monitor 16, and has the function of displaying a warning on the monitor 16 when the measured value is greater than a predetermined reference value. The monitor 16 is connected to the computer 15, and displays the level of the base plate receiving seat 12 output from the computer 15. In the illustrated example, the computer 15 is configured as a laptop computer with an attached monitor 16, and can be carried to various work sites.
[0036] 3 shows an example of the display on monitor 16, in which the circle indicates opening 19 and the arrow indicates the discharge direction of pump 11 relative to base plate receptacle 12. A and B indicate digital levels located before and after the discharge direction, and C and D indicate data transmitted from digital levels 14 located before and after the direction perpendicular to the discharge direction. This monitor 16 has, around the circle corresponding to opening 19, a level display unit 35 that is a simplification of the shape of an air bubble level, and a data display unit 36 that displays the digital data as is, and level display unit 35 is displayed in the same position as the actual digital level 14 on base plate receptacle 12.
[0037] Furthermore, when a tilt of a reference value or more occurs, a warning display unit 37 is provided, for example, on the level display unit 35, which displays a red color according to the direction of the tilt. In the illustrated example, the margin around the scale of the level display unit 35 is used as the warning display unit 37, and when the level display unit 35 tilts to the left or right, a portion according to the direction of the tilt is displayed in red, for example. To make it easier to grasp visually, an air bubble 38 that moves on the scale according to the tilt, similar to an air bubble level, is displayed in a schematic manner, and when the level is within the reference value, the bubble 38 is located in the center of the scale, and when a tilt occurs, the air bubble 38 is moved to the left or right, and the warning display unit 37 on the side to which the air bubble 38 is moved turns red.
[0038] In Figure 3, the measurement value of the data display 36 attached to the level display 35 of C and D is larger than the reference value, and therefore the warning display 37 is showing a warning, with the bubble 38 displayed biased to one side and the surrounding margins displayed in red or other colors. The data display 36 of the level display 35 shown in A and B is within the normal value range, and the bubble 38 is located in the center of the level display 35. The level display 35 shown in A and B also has a warning display 37 around the scale, but no warning is displayed.
[0039] The standard for this levelness can be changed as appropriate by the computer 15 depending on the size of the diameter of the pump 11 and the opening 19. In addition to the warning display unit 37, a function for issuing a warning sound may be provided.
[0040] In this embodiment, a warning is displayed when a tilt of 5 / 100 (0.05) mm or more occurs in the horizontal direction per 1 m (1000 mm) length. In the figure, the numerical values (-0.008, 0.007, -0.095, -0.118) on the data display section 36 indicate an example of the magnitude of the tilt (unit: mm) relative to the horizontal direction. In this way, by displaying the horizontality in units of 1 / 1000 mm, it becomes possible to measure even smaller tilts.
[0041] 2, a motor (electric motor) 41 for driving pump body 25 is disposed above pump body 25, and this motor 41 is attached in a state where it is level with respect to foundation (concrete) 42 that is placed parallel to foundation 20 on which pump body 25 is placed. An output shaft 43 of motor 41 is connected via coupling 45 to a rotating shaft 44 that is the main shaft of pump body 25.
[0042] (Base plate adjustment and installation method) Next, a method for adjusting and installing the base plate seat 12 of the pump 11 using the level measuring device 10 will be described. The base plate receiving seat 12 is placed on the foundation 20 while aligning the opening hole 21 of the foundation 20 with the opening 19 of the base plate receiving seat 12, and the anchor bolt 29 protruding from the foundation 20 is inserted into the fixing hole 28.
[0043] Next, the base plate support 12 is fixed to the foundation 20 by connecting the nut 51 to the anchor bolt 29, but before completely fixing it, the nut 51 is temporarily tightened and the levelness of the base plate support 12 is measured using the levelness measuring device 10.
[0044] First, as shown in FIG. 1, the four straight edges 13 are placed in predetermined positions on the support portion 18 of the base plate receiving seat 12 placed on the foundation 20, as described above, and a digital level 14 is placed on the approximate center of the top surface of each of the straight edges 13.
[0045] The level of the base plate support seat 12 is then measured using four digital levels 14. The measurements taken by the digital levels 14 are collected and stored in a computer 15, and after being processed, are displayed on a monitor 16 as shown in Figure 3. The worker visually checks the monitor 16 to confirm the level numerically, while adjusting the level (inclination) of the base plate support seat 12.
[0046] Since the monitor 16 displays all the measurements of the four digital levels 14, the worker can simultaneously check the level of the straight edge 13 on the single screen of the monitor 16, facilitating the level measurement work and the level adjustment work of the base plate receiving seat 12 while checking these measurements.
[0047] When adjusting the level of the base plate receiving seat 12 based on the level measurement results, the height around the base plate receiving seat 12 is adjusted to achieve a reference level by tightening nuts 51 at the required positions according to the measurement value, or by driving liners (spacers) 52A to 52C between the base plate receiving seat 12 and the foundation 20. These liners 52A to 52C include tapered liners 52A and 52B, which have a tapered surface on one side, and parallel liners 52C, which have parallel surfaces on both sides, and these are used in appropriate combinations.
[0048] Then, once the level of the base plate support seat 12 has been adjusted so that it is within the standard value, the nuts 51 of the anchor bolts 29 are tightened to the specified torque, and if necessary, the base plate support seat 12 and the liner 52 are spot welded together, and any gaps are filled with non-shrink grout or the like, and the base plate support seat 12 is then fixed to the foundation 20, completing the leveling work for the base plate support seat 12.
[0049] As explained above, in this installation method, the measurement values of the digital levels 14 on each straight edge 13 placed on the base plate support seat 12 are collected by the computer 15 and displayed all at once on the monitor 16 as shown in Figure 3, so that the level of the base plate support seat 12 in each direction can be confirmed via the monitor 16 without having to directly check the digital levels 14 on the base plate support seat 12. In this way, since there is no need to directly check the digital levels 14, the work of measuring the level is simplified, and even if the opening 19 has a large diameter, the installation and checking of the digital level 14 is simple, and the level of the base plate support seat 12 in each direction can be accurately adjusted while visually checking the level on the monitor 16. Furthermore, the straight edge 13 need only be placed on the periphery of the opening 19, rather than being placed so as to span the opening in the radial direction as shown in FIG. 5. Therefore, even if the straight edge 13 becomes longer due to the larger diameter of the opening 19, the positioning of the straight edge 13 relative to the opening 19 can be easily performed, and the levelness of the base plate 12 can be quickly adjusted by placing the straight edge 13 once.
[0050] As described above, the specific configuration of the present invention is not limited to the above-described embodiment, and design changes and the like are possible within the scope of the gist of the present invention.
[0051] In the measuring device of this embodiment, an example of a vertical shaft axial flow pump has been described as the pump 11 to be installed on the base plate support seat 12, but the pump 11 may also be a vertical shaft mixed flow pump other than an axial flow pump, and these can be used as appropriate when installed via the base plate support seat 12.
[0052] The same can also be applied to the installation of motors connected to these pumps. For example, the motor 41 shown in FIG. 2 includes a frame 46 corresponding to the base plate seat 12 of the pump 11, as shown in FIG. 5. The frame 46 is made up of multiple beam members 47 assembled vertically and horizontally, with an annular support member 48 fixed integrally to the center of the members. When installing the frame 46, anchor bolts (not shown) of the foundation 42 are inserted into the fixing holes 49 of the beam members 47 and temporarily fastened. In this state, the level of the upper surface 48a of the support member 48 is measured using multiple straight edges 13 and a digital level 14 placed on the upper surface 48a of the support member 48 along the periphery of the opening 55, as in the case of the pump 11 described above. While checking the measured values on the monitor 16, the frame 46 is positioned horizontally and each beam member 47 is fixed to the foundation 42. The base plate 49 of the motor 41 is then fixed onto the support members 48 of the frame 46. When installing a motor and a reducer, the reducer may be installed directly above the pump in place of the motor 41 in FIG. 2, and the motor may be connected to the reducer in a side-by-side state.
[0053] Furthermore, although not shown, the present invention can also be applied to other hydraulic machines, such as a hydraulic generator consisting of a hydraulic turbine and a generator. In the case of a hydraulic generator, for example, the hydraulic turbine is installed on the lower foundation 20 in Figure 2, and the generator is installed on the upper foundation 42. Then, as in the above embodiment, a base plate support and a platform are attached to each foundation while measuring the level with a straight edge and a digital level, and the base plates of the hydraulic turbine and generator are fixed to the base plate support and platform.
