Description
Technical Field
[0001] The utility model relates to the technical field of eddy current sensor installation, and more specifically, to an eddy current sensor installation device. Background Art
[0002] An eddy current sensor is a high-precision, non-contact measurement tool that works based on the principle of electromagnetic induction. It realizes measurement by detecting the eddy current effect generated by a metal conductor in a changing magnetic field. Due to its excellent measurement accuracy, fast response speed, and the characteristic of obtaining data without contacting the object to be measured, the eddy current sensor has become an indispensable important component in the field of modern industrial monitoring and diagnosis.
[0003] In the monitoring of hydro-generating units, eddy current sensors are particularly suitable for the measurement of swing and speed. These two parameters are crucial for evaluating and ensuring the stable operation of the units; swing measurement, that is, the radial vibration of a certain part of the main shaft of a hydro-generator relative to the fixed part of this part, also known as shaft relative vibration, can reflect the alignment of the unit's rotating shaft and the working state of the bearing; while speed measurement is directly related to the output power and efficiency of the unit and is a key parameter for the control and protection system.
[0004] The installation of eddy current sensors is usually close to the shaft to be measured to ensure measurement accuracy; however, due to the different diameters of the shafts on-site, the size of the surrounding space will also vary, which poses challenges to the installation and maintenance of eddy current sensors;
[0005] When maintaining the shaft to be measured or servicing the eddy current sensor, it is often necessary to disassemble and reinstall the eddy current sensor. Therefore, we need an installation device that enables the eddy current sensor to be displaced beside the shaft to be measured, facilitating the maintenance of the shaft to be measured and adapting to the measurement of various shafts to be measured.

[0038] The following is a detailed description of the present utility model.
[0039] As Figures 1-7 shown:
[0040] An installation device for an eddy current sensor 1 includes a base assembly 100 and a positioning assembly 200 that is slidably installed on the base assembly 100 and slides along the X-axis direction.
[0041] The base assembly 100 includes a support member and a telescopic mechanism 104 that is slidably installed on the support member and moves along the X-axis direction; the positioning assembly 200 is arranged on the telescopic mechanism 104.
[0042] The positioning assembly 200 includes a clamping mechanism 201 that is slidably installed on the telescopic mechanism 104 and is used for clamping and fixing the eddy current sensor 1, and an adjustment mechanism 202 that is in transmission cooperation with the clamping mechanism 201 and is used for driving the clamping mechanism 201 to slide on the telescopic mechanism 104.
[0043] Specifically, the support member includes a bottom plate 101, a connection hole 102 opened on the surface of the bottom plate 101, and a support column 103 installed on the bottom plate 101; the telescopic mechanism 104 is installed on the support column 103.
[0044] The device is installed next to the shaft to be measured by using the connection hole 102 on the bottom plate 101. The telescopic mechanism 104 allows the eddy current sensor 1 installed on the top to be telescopic in the radial direction (X-axis direction) of the shaft to be measured at any time, and adjusts the distance between the eddy current sensor 1 and the shaft to be measured, so as to make room for the shaft to be measured during maintenance or adjust the space required for installation, so as to adapt to installation spaces of different sizes next to shafts of various sizes;
[0045] During installation, the device is installed next to the shaft to be measured using the connection hole 102 on the base plate 101. The telescopic mechanism 104 allows the eddy current sensor 1 installed on the top to be telescoped in the radial direction of the shaft to be measured at any time, and adjusts the distance between it and the shaft to be measured, freeing up space when the shaft to be measured needs maintenance, and can adjust the space required for installation. The clamping mechanism 201 can quickly install and disassemble the eddy current sensor 1 to save time, and the adjustment mechanism 202 can fine-tune the position of the eddy current sensor 1.
[0046] In some possible implementations, the telescopic mechanism 104 includes a telescopic seat 104a installed on the support column 103 and provided with a slide groove 104b, a slide plate 104d located in the slide groove 104b and slidingly matched with the slide groove 104b along the X-axis direction, and a locking component provided on the telescopic seat 104a and used to lock the telescopic seat 104a and the slide plate 104d; a mounting groove connected to the slide groove 104b is provided on the top of the telescopic seat 104a, and the bottom of the positioning component 200 passes through the mounting groove and is installed on the slide plate 104d;
[0047] The locking assembly includes a plurality of groups of inclined grooves 104e arranged on the slide plate 104d along the X-axis direction, and a locking mechanism 104g arranged on the telescopic seat 104a and having one end passing through the telescopic seat 104a and used in conjunction with the inclined grooves 104e; a mounting groove 104f is arranged on the top of the telescopic seat 104a, and the locking mechanism 104g is located in the mounting groove 104f; the distances between two adjacent groups of inclined grooves 104e are equal; the top of the locking mechanism 104g passes through the mounting groove 104f, and the bottom of the locking mechanism 104g passes through the mounting groove 104f and is used in conjunction with the inclined groove 104e;
[0048] Furthermore, grooves are provided on both sides of the slide plate 104d along the X-axis direction, and the length direction of the groove is provided along the X-axis direction. A limit block 104c that slidably cooperates with the groove is provided on the telescopic seat 104a.
[0049] The slide plate 104d slides in the slide groove 104b. When the slide plate 104d extends a certain length from the telescopic seat 104a, the groove opened on the side of the slide plate 104d will be stuck by the limit block 104c, and the maximum extension length is achieved at this time. The inclined groove 104e and the locking mechanism 104g are used to position the slide plate 104d when it moves along the X-axis direction.
[0050] In some possible embodiments, the locking mechanism 104g includes a lifting plate 104g1 disposed in the mounting groove 104f and moving along the Z-axis direction, a first elastic component disposed above the mounting groove 104f and elastically connected to the lifting plate 104g1, and a limiting groove disposed at the bottom of the telescopic seat 104a and connected to the mounting groove 104f; one end of the lifting plate 104g1 close to the slide 104d passes through the limiting groove and is used in conjunction with the inclined groove 104e; and one end of the lifting plate 104g1 close to the slide 104d is provided with an inclined surface 104g2 used in conjunction with the inclined groove 104e.
[0051] When the slide plate 104d extends out from the telescopic seat 104a, the inclined surface 104g2 of a group of inclined grooves 104e will squeeze the end of the lifting plate 104g1 in the inclined groove 104e, so that the lifting plate 104g1 moves along the Z-axis direction to the side away from the slide plate 104d. The first elastic member 104g5 will be compressed during this period until the lifting plate 104g1 moves to the next group of inclined grooves 104e. When moving to the next group of inclined grooves 104e, the first elastic member 104g5 will recover from the compressed state to the initial state, so that the inclined surface 104g2 of this group of inclined grooves will contact the bottom end surface of the lifting plate 104g1. This process will be repeated until the slide plate 104d moves to a suitable position, and the position setting of the eddy current sensor 1 is completed.
[0052] When the axis to be tested needs to be maintained and space needs to be freed, the lifting plate 104g1 is directly lifted upward along the Z-axis direction to disengage it from the corresponding inclined groove 104e, and then the slide plate 104d is retracted into the telescopic seat 104a, which is convenient for adjustment and saves time.
[0053] In some possible implementations, a limiting plate 104g3 used in conjunction with the bottom of the limiting groove is disposed on the lifting plate 104g1, and the limiting plate 104g3 is disposed between the top of the sliding plate 104d and the bottom of the limiting groove. A stop plate 104g4 connected to the first elastic component and located in the mounting groove 104f is disposed on the lifting plate 104g1;
[0054] The limit plate 104g3 is set to limit the movement stroke of the corresponding lifting plate 104g1 along the Z-axis direction to avoid separation; when the top surface of the limit plate 104g3 abuts against the bottom of the limit groove, the lifting plate 104g1 cannot be lifted upward along the Z-axis direction; when the inclined surface of the inclined groove 104e contacts and cooperates with the inclined surface 104g2 of the lifting plate 104g1, the bottom surface of the limit plate 104g3 contacts and cooperates with the top surface of the slide plate 104d;
[0055] Further, the cross-section of the inclined groove 104e is in the shape of a right-angled triangle mechanism. The inclined surface is the surface where the hypotenuse of the right-angled triangle is located. One right-angled side of the right-angled triangle mechanism is on the top surface of the slide plate 104d, and the other right-angled side is on the side of the slide plate 104d close to the clamping mechanism 201; the hypotenuse is inclined from the side far away from the clamping mechanism 201 to the side close to the clamping mechanism 201, and the side of the hypotenuse far away from the clamping mechanism 201 is coplanar with the top surface of the slide plate 104d; the inclined surface 104g2 of the lifting plate 104g1 is arranged in the same way as the inclined surface of the inclined groove 104e;
[0056] Of course, the above inclined surface 104g2 can also be an arc surface;
[0057] In order to effectively reset the lifting plate 104g1 through the first elastic member 104g5; the first elastic component includes a first elastic member 104g5 installed on the abutment plate 104g4 and applying an elastic acting force along the Z-axis direction to the lifting plate 104g1, and a fixed shell 104g6 installed on the telescopic seat 104a and located above the installation groove 104f. One end of the first elastic member 104g5 far away from the abutment plate 104g4 is connected to the fixed shell 104g6;
[0058] It can be understood that when the slide plate 104d moves outward from the telescopic seat 104a, the inclined groove 104e will squeeze the lifting plate 104g1 and apply an upward acting force along the Z-axis to the lifting plate 104g1. After the first elastic member 104g5 receives this acting force, it will be in a compressed state; when the bottom of the lifting plate 104g1 enters a set of inclined grooves 104e again, the first elastic member 104g5 will recover from the compressed state to the initial state, driving the lifting plate 104g1 to move downward along the Z-axis to realize the contact of the two inclined surfaces 104g2;
[0059] Further, the first elastic member 104g5 is a compression spring.
[0060] In some possible implementation manners, the clamping mechanism 201 includes a clamping seat assembly 201a slidably matched with the slide plate 104d along the X-axis direction, a clamping mechanism 201b installed on the clamping seat assembly 201a and used for clamping the eddy current sensor 1, and a clamping member arranged on the clamping seat assembly 201a and used for fixing the clamping mechanism 201b; the clamping seat assembly 201a is in transmission connection with the adjusting mechanism 202;
[0061] The adjusting mechanism 202 is used to control the movement of the clamping seat assembly 201a along the X-axis direction, so that the eddy current sensor 1 clamped by the clamping mechanism 201b can further realize the fine adjustment of the position relative to the measured shaft, making the relative position more accurate, and further making the measurement accuracy higher;
[0062] In some possible embodiments, the adjusting mechanism 202 includes an adjusting seat 202a disposed on the sliding plate 104d, a threaded rod 202b disposed along the X-axis direction and screwed to the adjusting seat 202a, and one end of the threaded rod 202b passes through the adjusting seat 202a and is rotatably connected to the clamping seat assembly 201a;
[0063] The threaded rod 202b rotates around its axis, so that the position of the entire threaded rod 202b and the adjusting seat 202a changes, realizing movement along the X-axis direction. One end of the threaded rod 202b is rotatably connected to the clamping seat assembly 201a, so that the clamping seat assembly 201a can be driven to move along the X-axis direction on the sliding plate 104d, and the position of the eddy current sensor 1 clamped by the clamping mechanism 201b is adjusted; specifically, a bearing can be used between the threaded rod 202b and the clamping seat assembly 201a to realize the rotational connection between the two.
[0064] In some possible embodiments, the clamping seat assembly 201a includes an L-shaped plate 201a1 disposed on the top of the sliding plate 104d and rotatably connected to the threaded rod 202b, and a T-shaped block 201a2 disposed at the bottom of the L-shaped plate 201a1 and slidably engaged with the sliding plate 104d along the X-axis direction; a T-shaped groove for slidably engaging the T-shaped block 201a2 is provided on the sliding plate 104d;
[0065] The L-shaped plate 201a1 includes a horizontal plate slidably engaged with the sliding plate 104d along the X-axis direction, and a vertical plate vertically installed on the horizontal plate and cooperating with the horizontal plate to form an installation cavity. The T-shaped block is disposed at the bottom of the horizontal plate; the clamping mechanism 201b is installed in the installation cavity and is slidably engaged with the vertical plate in the Z-axis direction, and the threaded rod 202b is rotatably connected to the side of the vertical plate away from the installation cavity;
[0066] After the clamping mechanism 201b clamps and fixes the eddy current sensor 1, the clamping mechanism 201b is controlled to move downward, so that the clamping member is inserted and engaged with the clamping mechanism 201b, so that the clamping mechanism 201b is fixed, and further the eddy current sensor 1 is fixed;
[0067] In some possible embodiments, a receiving groove 201a3 for installing the clamping member is formed in the horizontal plate, and a card slot 201a4 communicating with the receiving groove 201a3 is formed in the horizontal plate; the receiving groove 201a3 is in a U-shaped structure with its opening disposed on the side away from the vertical plate; the card slot 201a4 is disposed on the top surface of the horizontal plate and communicates with the receiving groove 201a3;
[0068] The clamping member includes a Z-shaped block 201a5 located inside the accommodating groove 201a3 and clamped with the clamping mechanism 201b, and a second elastic member 201a6 installed in the accommodating groove 201a3 and applying a force to the Z-shaped block 201a5 in the Y-axis direction when the Z-shaped block 201a5 is clamped with the clamping mechanism 201b; the Z-shaped block 201a5 is slidably engaged with the L-shaped plate 201a1 in the Y-axis direction;
[0069] One end of the Z-shaped block 201a5 close to the card slot 201a4 is provided with a wedge surface 201a7 for cooperating with the clamping mechanism 201b; when the wedge surface 201a7 is not in contact with the clamping mechanism 201b, the cross-section of the side where the wedge surface 201a7 and the card slot 201a4 approach each other cooperates with a groove in the shape of a right triangle, and the wedge surface 201a7 will be on the hypotenuse of the right triangle;
[0070] The Z-shaped block 201a5 includes a first plate located in the accommodating groove 201a3 and arranged in the Y-axis direction, a second plate arranged in the X-axis direction and connected to one end of the first plate away from the card slot 201a4, and a third plate arranged parallel to the first plate and passing through the opening of the accommodating groove 201a3; a wedge surface 201a7 is provided at one end of the first plate away from the second plate; the second plate and the side surface of the accommodating groove 201a3 are respectively connected to the second elastic member 201a6;
[0071] After the bottom of the clamping mechanism 201b passes through the card slot 201a4 and is located inside the accommodating groove 201a3, it will abut against one end of the first plate away from the second plate, and the Z-shaped block 201a5 will move in the Y-axis direction to the side away from the clamping mechanism 201b, and the second elastic member 201a6 will change from the initial state to the compressed state or the stretched state; when the clamping mechanism 201b is inserted into the first plate, the second elastic member will return to the initial state, and the clamping mechanism 201b and the first plate will be fixed;
[0072] In some possible implementation manners, the clamping mechanism 201b includes a clamping seat 201b1 arranged on the side of the L-shaped plate 201a1 away from the adjusting mechanism 202 and moving in the Z-axis direction, collar rings 201b2 arranged at both ends of the clamping seat 201b1 in the Y-axis direction, arc-shaped elastic pieces 201b3 respectively arranged in the two collar rings 201b2 and approaching each other to form a clamping cavity, and clamping rollers 201b4 arranged on the side where the two arc-shaped elastic pieces 201b3 approach each other and above the collar rings 201b2; a wedge block 201b5 for cooperating with the wedge surface 201a7 is arranged at the bottom of the clamping seat 201b1, and a slot 201b6 is formed between the wedge block 201b5 and the bottom of the clamping seat 201b1; there are two clamping rollers 201b4 on each arc-shaped elastic piece 201b3, and they are arranged in the Z-axis direction;
[0073] A guiding groove is provided on the vertical plate and arranged along the Z-axis direction, and a guiding block slidably engaged with the guiding groove is designed on the clamping seat 201b1, thereby effectively guiding. When the wedge block 201b5 moves towards the side close to the horizontal plate on the clamping seat 201b1, it will pass through the clamping groove 201a4 and enter the accommodating groove 201a3. As the clamping seat 201b1 continues to move downward, it will squeeze the first plate to move towards the side away from the clamping groove 201a4, and the second elastic member 201a6 will be stretched or compressed. When the bottom of the wedge block 201b5 cannot move along the Z-axis direction, under the action of the second elastic member 201a6, one end of the first plate close to the slot 201b6 will be inserted into the slot 201b6 to fix the clamping seat 201b1.
[0074] When installing the eddy current sensor 1, place it in the clamping cavity, and apply an elastic force to the eddy current sensor 1 through two groups of arc-shaped elastic pieces 201b3 to clamp and fix it.
[0075] Specifically, the openings of the two groups of arc-shaped elastic pieces 201b3 are arranged on the sides away from each other.
[0076] While the clamping seat 201b1 slides downward, the collar rings 201b2 on both sides of the clamping seat 201b1 will drive the arc-shaped elastic pieces 201b3 to move towards the middle. Then, the pinch rollers 201b4 at the top of the arc-shaped elastic pieces 201b3 will clamp the eddy current sensor 1. When the eddy current sensor 1 is installed in place, the wedge block 201b5 will pass through the clamping groove 201a4 and be located in the accommodating groove 201a3, and the end of the Z-shaped block 201a5 with the wedge-shaped surface 201a7 will be inserted into the slot 201b6.
[0077] A gap is formed between the first plate and the bottom of the accommodating groove 201a3. When the bottom of the wedge block 201b5 contacts the bottom of the accommodating groove 201a3, the bottom of the slot 201b6 and the bottom of the first plate are coplanar.
[0078] When disassembling the eddy current sensor 1, only need to control the third plate to slide along the Y-axis direction from the outside of the telescopic seat 104a towards the side away from the clamping groove 201a4, which can drive the Z-shaped block 201a5 away from the clamping seat 201b1. At this time, the arc-shaped elastic pieces 201b3 will rebound and squeeze the clamping seat 201b1 upward, and the pinch rollers will no longer clamp the eddy current sensor 1, and the eddy current sensor 1 can be easily removed.
[0079] The utility model is not limited to the foregoing specific embodiments. The utility model extends to any new feature disclosed in this specification or any new combination, as well as any new method or process step disclosed or any new combination.
