[0060] In addition, it should be noted that the use of "first", "second", and the like words of distinction do not have a special meaning, and are merely used to distinguish corresponding parts, and therefore should not be construed as limiting the scope of protection of the present application. In addition, although the terms used in the present application are selected from commonly known terms, some terms mentioned in the specification of the present application can be selected by the applicant according to his or her judgment, and the detailed meanings thereof are explained in the relevant part of the description. In addition, the present application is not to be understood only by the actual terms used, but also by the meaning implied by each term.

[0061] However, the size or positional relationship of the components shown in the drawings is sometimes exaggerated for clear illustration. Furthermore, in the following description, the same name, symbol is used to indicate the same or homogeneous components, and detailed description thereof is appropriately omitted. Furthermore, each element constituting the present application can be in a form in which a plurality of elements are constituted by the same component to use one component for a plurality of elements, or conversely, a plurality of components can share the function of one component. In addition, the contents described in some embodiments, modes of implementation, etc. can be used in other embodiments, modes of implementation, etc. In addition, in the present specification, "upper" is not limited to the case where it is in contact with the upper surface, but also includes the case where it is formed separately upward, and is also used with the meaning that it also includes the case where there is an intervening layer between layers.

[0062] It should be understood that, although the following introduction of the probe mounting tool installation object with the installation of the eddy current probe as an example, but not limited to, any probe with external thread can be applied to the installation tool described in the embodiment, to achieve reliable fixation of the probe, especially to ensure the stability of the installation structure in the vibration environment, to ensure accurate monitoring of the vibration and displacement of the monitoring assembly for the equipment, so as to accurately assess the operation of the equipment, to ensure the normal and reliable operation of the equipment.

[0063] Reference Figure 2 And Figure 6 As shown in some embodiments, the monitoring assembly 1000 can include a probe 200 and the following embodiments will be described in detail probe mounting tool 100, the outer wall of the probe 200 has external thread 201, the probe 200 is fixedly installed on the mounting bracket 300 through the probe mounting tool 100, to achieve reliable fixation of the probe, especially to ensure the stability of the installation structure in the vibration environment, to ensure accurate monitoring of the vibration and displacement of the monitoring assembly for the equipment, so as to accurately assess the operation of the equipment, to ensure the normal and reliable operation of the equipment.

[0064] The specific fixed mounting structure can be that the base 1 of the probe mounting tool 100 is welded to the mounting bracket 300, but not limited to, other fixed structure can also be used.

[0065] The mounting bracket 300 is fixedly installed with one or more probe mounting tools 100, it can be understood that the number of probe mounting tools 100 is generally corresponding to the number of probes 200, therefore Figure 2 The three probe mounting tools 100 shown in the figure are only examples. Reference Figures 2 to 6 As shown in some embodiments, the probe mounting tool 100, comprising a base 1 and a mounting and fixing part 2.

[0066] The base 1, as described above, can be fixed to the mounting bracket 300 by welding and other mounting structures, the base 1 has a probe hole 11, which can make the probe 200 through to detect, so as to accurately monitor the vibration and displacement of the equipment, the outer wall of the probe 200 has external thread 201.

[0067] The installation fixing part 2, as its name implies, is used to contact the probe 200 directly to fix it. The installation fixing part 3 is arranged above the probe hole 11 (in the up-down direction, for example, the Z direction shown in the figure). The installation fixing part 2 includes a first part 21 and a second part 22. The first part 21 has a first half hole 211, and the inner wall of the first half hole 211 has a first internal thread 2111. The second part 22 has a second half hole 221, and the inside of the second half hole 221 has a second internal thread 2211. The rotation directions of the first internal thread 2111 and the second internal thread 2211 are opposite. The first part 21 and the second part 22 can move relatively close to each other so that the first half hole 211 and the second half hole 221 form a fixing hole 23 for fixing the probe 200.

[0068] The first internal thread 2111 and the second internal thread 2211 are threads that cooperate with the external thread 201. The size parameters of the first internal thread 2111 and the second internal thread 2211 are substantially the same, and the only difference is the difference between the internal and external threads. The rotation directions of the first internal thread 2111 and the second internal thread 2211 are opposite. For example, the outer wall of the probe 200 can have a left-handed or right-handed external thread 201. One of the first internal thread 2111 and the second internal thread 2211 is left-handed, and the other is right-handed. The direction of relative movement between the first part 21 and the second part 22 can be the X direction shown in the figure, but is not limited thereto.

[0069] At least one of the first part 21 and the second part 22 is connected with a first limiting part 24. The base 1 has a second limiting part 12. When the first half hole 211 and the second half hole 221 form the fixing hole 23, the first limiting part 24 cooperates with the second limiting part 12 to limit the movement of the first part 21 or the second part 22 having the first limiting part 24.

[0070] The above embodiment has the beneficial effect that the inventor found that by forming the fixing hole 23 for fixing the probe 200 with the first half hole 211 and the second half hole 221, and by making the rotation directions of the first internal thread 2111 and the second internal thread 2211 opposite, the probe 200 can be stably fixed. In combination with the limiting structure that the first limiting part 24 cooperates with the second limiting part 12, the probe can maintain a stable installation position during monitoring, especially under conditions of large vibration load and alternating vibration load. The problem of probe loosening during monitoring in the double-nut fixing structure of the comparative solution is overcome, the accurate monitoring of the vibration and displacement of the equipment by the monitoring assembly is ensured, and thus the operation of the equipment is accurately evaluated to ensure the normal and reliable operation of the equipment.

[0071] Continuing to refer to Figures 3 to 6In some embodiments, the structure in which the first part 21 and the second part 22 are relatively moved to approach each other can be that the base 1 has a track 13, the first part 21 is a moving part, and the second part 22 is a fixed part, for example, the second part 22 can be welded to the base 1, and the structures of the first part 21 and the second part 22 can be Figure 3 the block structure shown in FIG. 1, but not limited thereto. The first part 21 can be relatively moved to the second part 22 along the moving direction defined by the track 13 to approach each other, so that the first half hole 211 and the second half hole 221 form the fixed hole 23 in which the probe 200 is installed and fixed. With the structure of guide rail-sliding fit, the stroke of the first part 21 or the second part 22 as the moving part can be stable without shaking. With the structure in which one is the moving part and the other is the fixed part, it is more stable and reliable than the structure in which both are moving parts.

[0072] With reference to Figure 3 and Figure 4 In some embodiments, on the basis of the track structure, the first part 21 further has a guide hole 212 extending along the moving direction, and the probe installation tool 100 further includes a guide rod 213 which is disposed through the guide hole 212. Through the cooperation of the guide hole 212 and the guide rod 213, the movement of the first part 21 on the specified track 13 is more stable, and further shaking is avoided.

[0073] With reference to Figure 3 The structure for controlling the movement and stopping of the moving part can be that the probe installation tool 100 further includes an operating part 15 and a locking part 16. When the locking part 16 releases the locking of the operating part 15, the operating part 15 can receive operating force or operating torque, and the output of the operating part 15 drives the first part 21 to move. With the structure of manual operation, the moving position of the first part 21 can be accurately adjusted, and the installation and fixation are more reliable.

[0074] With reference to Figure 3As shown, in some embodiments, the specific structure of the operating member 15 and the locking member 16 may be as follows: the operating member 15 includes a screw 151, which abuts against the first portion 21; the locking member 16 includes a nut 161; the screw 151 is installed in the threaded hole 17 of the base 1, and the screw 151 has a first threaded portion 1511. The first threaded portion 1511 cooperates with the nut 161 so that the screw 151 can be locked to the base 1 by the nut 161, and after unlocking, the screw 151 moves along the axial direction of the threaded hole 17 to drive the first portion 21 to move along the moving direction. The structure driven by the screw and nut is simple, low in cost, and easy to operate. For example, the position can be locked by tightening the nut 161 with a wrench or other tools, and unlocked by loosening the nut 161 with a wrench or other tools. The screw 151 can be rotated by hand or by applying force manually with a tool.

[0075] In some embodiments, reference Figure 3 As shown, the first portion 21 has a first groove 214, and one end of the screw 151 has a cap 1512. The cap 1512 abuts against the first groove 214 to drive the first portion 21 to move along the moving direction. This makes the movement of the first portion 21 driven by the screw 151 smoother and prevents shaking.

[0076] Continue to refer to Figure 4 as well as Figure 5 In some embodiments, the specific structure for the cooperation between the first limiting part 24 and the second limiting part 12 can be as follows: the first limiting part 24 includes a spring piece 241 and a first limiting body 242. The spring piece 241 is connected to the first segment 21 or the second segment 22 on one side and to the first limiting body 242 on the other side. The second limiting part 12 includes a second groove 121. When the first half-hole 211 and the second half-hole 221 form a fixing hole 23, the first limiting body 242 is embedded and fixed in the second groove 121, so that the first limiting part 24 and the second limiting part 12 cooperate accordingly. The spring piece 241, as the name suggests, is a component with a certain elasticity. The spring piece 241 can be made of materials such as spring steel. The structure of the spring piece 241 can better absorb vibration and thus prevent shaking, making the embedded and fixed structure of the first limiting body 242 and the second groove 121 more stable and reliable. In some embodiments, refer to Figure 5 As shown, the first limiting body 242 is a rod-shaped structure, and the concave shape of the second groove 121 corresponds to the outer wall shape of the rod-shaped structure, for example... Figure 5As shown in the drawings, the first limiting body 242 is a cylindrical rod structure, and the recessed shape of the second groove 121 corresponds to the outer wall shape of the rod structure, which is an arc-shaped groove. Similarly, if the first limiting body 242 is a prismatic rod structure, such as a cuboid, then the recessed shape of the second groove 121 corresponds to the outer wall shape of the rod structure, which is a square groove. In this way, the embedded fixing structure of the first limiting body 242 and the second groove 121 is more stable and reliable.

[0077] In summary, the probe mounting tool and the monitoring assembly introduced in the above embodiments have the beneficial effect that the first half hole 211 and the second half hole 221 constitute a fixing hole 23 for mounting and fixing the probe 200, and the first internal thread 2111 and the second internal thread 2211 have opposite rotation directions, which can stably mount and fix the probe 200. In combination with the limiting structure of the corresponding cooperation of the first limiting part 24 and the second limiting part 12, the probe can maintain the stability of the installation position during the monitoring process, especially in the case of large vibration load and alternating vibration load. The problem of probe loosening during the monitoring process of the double-nut fixing structure of the comparative scheme is overcome, the accurate monitoring of the vibration and displacement of the equipment by the monitoring assembly is ensured, the operation of the equipment is accurately evaluated, and the normal and reliable operation of the equipment is ensured.

[0078] Although the present application has been described with reference to the current specific embodiments, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and various equivalent changes or replacements can be made without departing from the spirit of the present application. Therefore, any changes or modifications of the above embodiments within the scope of the spirit of the present application will fall within the scope of the claims of the present application.
