Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering unit detection, and in particular to a large-scale pump station unit maintenance wear detection device. Background Art

[0002] A pump station is a device that can provide hydraulic and pneumatic power with a certain pressure and flow. In order to realize the normal water inlet and outlet functions of the pump station, the pump station unit includes main components such as motors, pumps, oil tanks and auxiliary equipment, as well as some shared equipment, compressed air equipment, flushing equipment, water supply and drainage equipment, ventilation equipment, lifting equipment, etc.

[0003] The most critical and core equipment in the pump station unit is the motor. The motor determines the efficiency of the entire pump station in drainage and irrigation. Therefore, the motor needs to be maintained on a daily basis. During the daily maintenance and repair of the motor, the wear of the motor shaft needs to be detected. The common way to detect the wear of the motor shaft is manual detection, that is, the diameter of the shaft is measured multiple times by an outside micrometer, vernier caliper or caliper, and finally the multiple sets of data are processed to obtain the wear of the motor shaft.

[0004] Regarding the above-mentioned related technologies, in actual measurement, technicians are required to keep the measuring tool always perpendicular to the axis of the shaft, which places high demands on the technicians. When the measuring tool is not perpendicular to the axis of the shaft, the obtained data is inaccurate, which affects the subsequent judgment of the normal service life of the motor. In addition, during multiple measurements of the motor shaft, the manual measurement operation is inefficient, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a large-scale pump station unit maintenance wear detection device. Figure 1 A large-scale pump station unit maintenance wear detection device includes a fixed machine base 1, a detection ring 31 arranged on the fixed machine base 1, and a fixed component 2 arranged on the fixed machine base 1 for making the motor shaft 12 and the detection ring 31 always coaxial. The detection ring 31 is arranged perpendicular to the length direction of the fixed machine base 1, and the detection ring 31 is rotatably arranged on the fixed machine base 1. The rotation axis of the detection ring 31 is consistent with the length direction of the fixed machine base 1. A plurality of groups of detection members 32 are arranged on the inner circumferential wall of the detection ring 31. The detection members 32 are arranged toward the axis of the detection ring 31. The plurality of groups of detection members 32 are evenly spaced along the circumference direction of the detection ring 31. In the present application, four groups of detection members 32 are arranged. In other embodiments, the detection members 32 can also be provided with two groups, three groups, five groups, etc., and the arrangement method is consistent with the arrangement method of the present application.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The fixing assembly 2 includes fixing frames 21 symmetrically arranged on opposite sides of the detection ring 31. The top ends of the two fixing frames 21 are both open. One of the fixing frames 21 is provided with a receiving groove 22. The receiving groove 22 is rectangular, and the width of the receiving groove 22 is consistent with the flat key width of the motor shaft 12. The top end of the other fixing frame 21 is provided with a positioning groove 25. The positioning groove 25 is semicircular, and the diameter of the positioning groove 25 is consistent with the diameter of the motor shaft 12.

[0036] The fixing assembly 2 includes a first horizontal member arranged on a fixing frame 21 and a second horizontal member arranged on another fixing frame 21. The first horizontal member includes a clamping block 23 fixed to a sliding position on the fixing frame 21. The clamping block 23 is provided with two groups. The two groups of clamping blocks 23 are respectively located on both sides of the accommodating groove 22, and the two groups of clamping blocks 23 are movable to approach and move away from each other, and the side of the two clamping blocks 23 close to each other is fitted with the flat key of the motor shaft 12. At the same time, an adjusting screw 24 is rotatably arranged in the fixing frame 21. The two groups of clamping blocks 23 are both threadedly arranged on the adjusting screw 24. The adjusting screw 24 is provided with an external thread with the same pitch and opposite thread, and one end of the adjusting screw 24 passes through the fixing frame 21 and is fixedly connected with an adjusting handle.

[0037] Therefore, when it is necessary to perform wear inspection on the motor shaft 12, the technician mounts the motor shaft 12 on the fixed frame 21, and cooperates with the two sets of clamping blocks 23 through the accommodating groove 22, so as to clamp the flat key of the motor shaft 12 and realize the horizontal positioning of the motor shaft 12.

[0038] The second horizontal member includes a positioning ring 26 arranged on the fixing frame 21, and the positioning groove 25 and the positioning ring 26 together form a circular clamping cavity to clamp the motor shaft 12, and mounting holes are provided on the fixing frame 21 and the positioning ring 26. When the motor shaft 12 passes through the detection ring 31 and is mounted on the two fixing frames 21, the two clamping blocks 23 are first brought close to each other to clamp the flat key of the motor shaft 12, and then the technician fixes the positioning ring 26 and the fixing frame 21 by screwing the bolts into the mounting holes, thereby fixing the vertical position of the motor shaft 12.

[0039] The fixed base 1 is provided with a mounting ring 3 which is slidably mounted, the detection ring 31 is rotatably mounted on the mounting ring 3, and the fixed base 1 is also provided with a displacement screw 11 which is threadedly connected to the mounting ring 3, and the fixed base 1 is also provided with a limit rod which is slidably arranged through the mounting ring 3. Therefore, when performing wear detection on different positions of the motor shaft 12, the technician can rotate the displacement screw 11 to slide the mounting ring 3 and the detection ring 31 along the length direction of the fixed base 1, thereby realizing the wear detection on different positions of the motor shaft 12.

[0040] Further references Figure 4 and Figure 5The detection member 32 includes a fixed cylinder 321 fixed on the detection ring 31. The fixed cylinder 321 is hollow, and a detection probe 322 is slidably arranged in the fixed cylinder 321. One end of the detection probe 322 protrudes from the fixed cylinder 321 and is arranged toward the axis of the detection ring 31. The detection probe 322 protrudes from one end of the fixed cylinder 321 and is movably fitted with the outer peripheral wall of the motor shaft 12. A detection spring is fixedly connected between the detection probe 322 and the inner wall of the fixed cylinder 321. The detection spring is always in a compressed state, that is, it always provides a tendency for the detection probe 322 to approach the axis of the detection ring 31.

[0041] At the same time, a perspective hole 324 is opened on the outer peripheral wall of the fixed cylinder 321, and a first scale line 325 is provided at the perspective hole 324 of the fixed cylinder 321. A scale plate 323 is fixedly connected to the detection probe 322, and the scale plate 323 always fits with the inner peripheral wall of the fixed cylinder 321. Therefore, the scale plate 323 can limit the sliding direction of the detection probe 322 and indicate the reading at the same time. Therefore, when performing wear detection on the motor shaft 12, the technician only needs to observe the reading at the scale plate 323 to read the wear amount at this time.

[0042] At the same time, in order to facilitate the rotation adjustment of the detection ring 31, an adjustment member 33 is also provided on the mounting ring 3, and an adjustment groove 332 is provided on the outer peripheral wall of the mounting ring 3. The adjustment member 33 includes an adjustment block 331 fixed on the detection ring 31, and the adjustment block 331 protrudes from the adjustment groove 332 for the convenience of the technician to turn it. At the same time, a pointer 34 is also fixedly connected to the detection ring 31, and a second scale line 341 is provided on the outer peripheral wall of the mounting ring 3. The pointer 34 and the second scale line 341 are both arranged toward the axis of the detection ring 31. Therefore, when the technician turns the adjustment block 331 to rotate the detection ring 31, the accurate rotation adjustment of the detection ring 31 can be achieved through the reading of the pointer 34.

[0043] At the same time, in order to improve the surface quality of the motor shaft 12, the side of the detection probe 322 that fits against the end of the motor shaft 12 is spherical, and the fixed cylinder 321 is also provided with a fine-tuning rod 35 for fine-tuning the detection probe 322. The fine-tuning rod 35 is threadedly connected to the end of the fixed cylinder 321 away from the axis of the detection ring 31, and the end of the fine-tuning rod 35 that penetrates into the fixed cylinder 321 is movably pressed against the detection probe 322. In some special cases, when it is necessary to record accurate readings, the technician rotates the fine-tuning rod 35 to make the detection probe 322 press against the surface to be detected of the motor shaft 12, thereby obtaining accurate readings, thereby improving subsequent maintenance judgments and service life judgments of the motor shaft 12.

[0044] The implementation principle of the wear detection device for maintenance of a large pump station unit in the embodiment of the present application is as follows: when performing wear detection on the motor shaft 12, the technician first passes the motor shaft 12 through the detection ring 31 and mounts it on the fixing frame 21, so that the flat key of the motor shaft 12 is clamped in the receiving groove 22, and the clamping block 23 clamps the flat key of the motor shaft 12 by rotating the adjusting screw 24; then the technician closes the positioning ring 26, so that the positioning ring 26 and the fixing frame 21 clamp the motor shaft 12 to a limited position; at this time, the technician rotates the detection ring 31, so that the pointer 34 is located at the initial scale on the second scale line 341 at this time, and then the position of the scale plate 323 at the first scale line 325 on the fixed cylinder 321 is recorded to obtain the first set of data at this time, and then the technician turns the adjustment block 331 to rotate the detection ring 31, records the angle of the second scale line 341 at this time, and records the position of the scale plate 323 at the first scale line 325 on the fixed cylinder 321, and then continues to rotate the moving angle to obtain multiple sets of data, and the wear amount of the motor shaft 12 at this time can be obtained by processing the data;

[0045] When it is necessary to detect wear at different locations of the motor shaft 12 , the technician rotates the displacement screw 11 to drive the mounting ring 3 and the detection ring 31 to slide along the length direction of the fixed base 1 , thereby realizing wear detection at different locations of the motor shaft 12 .

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
