Description

Technical Field

[0001] This application belongs to the field of centrifugal pump technology, and in particular relates to a tooling structure for mounting a shaft vibration probe. Background Technology

[0002] In the structure of centrifugal pumps, real-time monitoring of the vibration of the pump spindle is a core technical means to ensure the safe operation of the pump. Typically, a shaft vibration probe is used as a sensor to monitor the changes in the vibration amplitude and frequency of the spindle, thereby providing early warning of abnormal vibrations caused by faults such as bearing wear, shaft imbalance, or loose components. This helps staff to detect problems early and take maintenance measures to avoid serious damage to the equipment or even shutdown accidents.

[0003] Traditional shaft vibration probes typically employ a fixed mounting design, where the probe is directly locked to the mounting fixture via rigid connectors (such as fixed flanges or non-adjustable threads). While this structure ensures installation stability, it has significant drawbacks in practical applications: due to substantial differences in spindle diameter, installation space, and monitoring requirements among various devices, fixed fixtures cannot accommodate multiple probe and spindle sizes. This necessitates users equipping specific models of probes and matching fixtures for spindles of different dimensions, increasing procurement and inventory costs. Furthermore, frequent fixture changes or custom probe replacements are required during installation, making the process cumbersome and time-consuming. Therefore, it is necessary to address these technical issues. Utility Model Content

[0004] The purpose of this application is to provide a tooling structure for mounting an axial vibration probe, so as to solve the technical problem of high production cost of axial vibration probes in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a tooling structure for mounting a shaft vibration probe, comprising:

[0006] The connecting pipe is used to install the target probe;

[0007] The first connector is movably fitted onto the conduit and used to connect to the target bearing body;

[0008] The second connector is connected to the first connector and through which the conduit passes. The channel on the second connector through which the conduit passes forms a pointed inner conical surface at the end away from the first connector.

[0009] The ferrule is movably fitted onto the conduit and forms an outer conical surface coaxial with the inner conical surface. The ferrule abuts against the inner conical surface through the outer conical surface.

[0010] A locking nut is threaded to the second connector, and the thread between the locking nut and the second connector is coaxial with the conduit. A ferrule is located axially between the locking nut and the second connector and abuts against the locking nut. The ferrule is also an elastomeric structure and is guided by the inner conical surface to form a damped connection with the conduit as the locking nut rotates relative to the second connector and approaches each other.

[0011] Optionally, the second connector is threadedly connected to the first connector;

[0012] The connecting thread between the second connector and the first connector is coaxial with the conduit.

[0013] Optionally, a guide portion is formed on the second connector;

[0014] The guide portion is slidably connected to the first connector, and the sliding direction of the guide portion relative to the first connector is parallel to the axial direction of the conduit.

[0015] Optionally, the tooling structure for mounting the shaft vibration probe further includes an adjusting nut;

[0016] The adjusting nut is threaded onto the second connector and is used to abut against the first connector in the axial direction of the conduit.

[0017] Optionally, the tooling structure for mounting the shaft vibration probe further includes a sealing joint that is sealed on the wiring conduit;

[0018] The sealing joint abuts against the locking nut and the ferrule at its two ends along the axial direction of the wiring pipe, respectively.

[0019] Optionally, the sealing joint and the ferrule form matching tapered contact surfaces;

[0020] The tapered contact surface is inclined relative to the axial direction of the conduit, and the sealing joint and the ferrule abut against each other through the tapered contact surface.

[0021] Optionally, the conduit forms a threaded hole for mounting the target probe.

[0022] Optionally, the tooling structure for mounting the shaft vibration probe further includes a pipe connector connected to the first connector, the pipe connector forming a mounting hole for the wiring conduit to pass through and for connecting the protective pipe.

[0023] Optionally, the tooling structure for mounting the shaft vibration probe further includes a first fastening nut threaded to the first connector, a second fastening nut threaded to the pipe connector, and a third fastening nut for threading the first fastening nut and the second fastening nut together.

[0024] The pipe fitting is detachably connected to the first fitting via the first fastening nut, the second fastening nut, and the third fastening nut.

[0025] The beneficial effects of the shaft vibration probe mounting fixture structure provided in this application are as follows: Compared with the prior art, in the shaft vibration probe mounting fixture structure provided in this application, the wiring conduit for mounting the target probe moves through the first connector and the second connector. Because the channel on the second connector through which the wiring conduit passes forms an inner conical surface with its tip close to the first connector at the end furthest from the first connector, and because the ferrule coaxially fitted on the wiring conduit forms an outer conical surface coaxial with the inner conical surface, and the outer and inner conical surfaces abut against each other, when the locking nut threaded onto the second connector rotates relative to the second connector and moves closer to each other, the ferrule, which is made of elastic material and is located axially between the locking nut and the second connector, can form a damped connection with the wiring conduit through the mutual engagement of the inner and outer conical surfaces. Therefore, the tooling structure for installing the shaft vibration probe in this application can adjust the tightness between the ferrule and the connecting pipe by adjusting the locking nut relative to the second connector. In this way, after the first connector is fixed on the target bearing body, the connecting pipe can also adjust the position of the target probe by moving relative to the first connector. Thus, it is not necessary to customize corresponding probes separately for different spindle diameters, which can significantly reduce the production cost of shaft vibration probes.

[0034] Please refer to the following: Figure 1 and Figure 2 The following describes a fixture structure for installing a shaft vibration probe according to an embodiment of this application. This fixture structure includes a wiring conduit 101, a first connector 102, a second connector 103, a ferrule 105, and a locking nut 107. Wherein:

[0035] The connector 101 is used to mount the target probe 201; the first connector 102 is movably fitted onto the connector 101 and is used to connect the target bearing body 202; the second connector 103 is connected to the first connector 102 and allows the connector 101 to pass through, the channel on the second connector 103 for the connector 101 to pass through forms an inner conical surface 104 with a pointed tip close to the first connector 102 at the end away from the first connector 102; the ferrule 105 is movably fitted onto the connector 101 and forms an outer conical surface 106 coaxial with the inner conical surface 104, the ferrule 105 passes through the outer conical surface 106. Surface 106 abuts against inner conical surface 104; locking nut 107 is threadedly connected to second connector 103 and the connecting thread between locking nut 107 and second connector 103 is coaxial with conduit 101; ferrule 105 is located between locking nut 107 and second connector 103 in the axial direction of conduit 101 and abuts against locking nut 107; ferrule 105 is also an elastomeric structure and can be guided by inner conical surface 104 to form a damped connection with conduit 101 during the rotation of locking nut 107 relative to second connector 103.

[0036] According to the structure provided in this embodiment, in the shaft vibration probe mounting fixture structure provided in this embodiment, the conduit 101 for mounting the target probe 201 moves through the first connector 102 and the second connector 103. Since the channel on the second connector 103 through which the conduit 101 passes forms an inner conical surface 104 with its tip close to the first connector 102 at the end away from the first connector 102, and since the ferrule 105 coaxially fitted on the conduit 101 forms an outer conical surface 106 coaxial with the inner conical surface 104, and the outer conical surface 106 and the inner conical surface 104 abut against each other, when the locking nut 107 threaded onto the second connector 103 rotates relative to the second connector 103 and moves closer to each other, the ferrule 105, which is axially positioned between the locking nut 107 and the second connector 103 and is made of elastic material, can form a damped connection with the conduit 101 through the mutual cooperation of the inner conical surface 104 and the outer conical surface 106. Therefore, in this embodiment, the tooling structure for mounting the shaft vibration probe can adjust the tightness between the sleeve 105 and the connecting pipe 101 by adjusting the locking nut 107 relative to the second connector 103. In this way, after the first connector 102 is fixed on the target bearing body 202, the connecting pipe 101 can also adjust the position of the target probe 201 by moving relative to the first connector 102. Thus, it is not necessary to customize corresponding probes for different diameters of the spindle 203, which can significantly reduce the production cost of the shaft vibration probe.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The second connector 103 is threadedly connected to the first connector 102; the connecting thread between the second connector 103 and the first connector 102 is coaxial with the connecting pipe 101. According to the structure provided in this embodiment, since the connecting thread between the second connector 103 and the first connector 102 is coaxial with the connecting pipe 101, when the locking nut 107 is locked onto the second connector 103 and the ferrule 105 is secured to the connecting pipe 101, the second connector 103, threadedly connected to the first connector 102, can also finely adjust the axial position of the connecting pipe 101 by rotating relative to the first connector 102. This allows the target probe 201 connected to the connecting pipe 101 to be adjusted more flexibly and precisely, which helps to further reduce the production cost of the shaft vibration probe.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 A guide portion 108 is formed on the second connector 103; the guide portion 108 is slidably connected to the first connector 102, and the sliding direction of the guide portion 108 relative to the first connector 102 is parallel to the axial direction of the connecting pipe 101. According to the structure provided in this embodiment, the guide portion 108 formed on the second connector 103 can effectively ensure the movement stability of the second connector 103, so the target probe 201 connected to the connecting pipe 101 can have a more precise adjustment effect, thereby helping to further reduce the production cost of the shaft vibration probe.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The tooling structure for mounting the shaft vibration probe also includes an adjusting nut 109; the adjusting nut 109 is threadedly connected to the second connector 103 and is used to abut against the first connector 102 in the axial direction of the connecting pipe 101. According to the structure provided in this embodiment, the adjusting nut 109 threadedly connected to the second connector 103 can lock or loosen the relative positional relationship between the first connector 102 and the second connector 103 by abutting against or moving away from the first connector 102. In this way, the connecting pipe 101 connected to the second connector 103 can ensure better relative positional stability and facilitate adjustment of its axial position, thereby helping to further reduce the production cost of the shaft vibration probe.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2The tooling structure for installing the shaft vibration probe also includes a sealing joint 110 that is sealed and fitted onto the wiring conduit 101; the two ends of the sealing joint 110 in the axial direction of the wiring conduit 101 respectively abut against the locking nut 107 and the ferrule 105. According to the structure provided in this embodiment, the sealing joint 110, whose two ends abut against the locking nut 107 and the ferrule 105 respectively, can prevent external impurities from entering the target bearing body 202 by sealing the connection with the wiring conduit 101, ensuring that the cleanliness of the internal components of the target bearing body 202 is not affected by the outside, thereby helping to improve the service life of the spindle and the internal components of the target bearing body 202.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 A matching tapered contact surface 111 is formed on the sealing joint 110 and the ferrule 105; the tapered contact surface 111 is inclined relative to the axial direction of the connecting pipe 101, and the sealing joint 110 and the ferrule 105 abut against each other through the tapered contact surface 111. According to the structure provided in this embodiment, the tapered contact surface 111 formed on the sealing joint 110 and the ferrule 105 can cooperate with the inner tapered surface 104 and the outer tapered surface 106 to better fix the ferrule 105, so that the connecting pipe 101 can form a more stable connection with the second joint 103, which also helps to further reduce the production cost of the shaft vibration probe.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The connector 101 forms a threaded hole 112 for mounting the target probe 201. According to the structure provided in this embodiment, the threaded hole 112 formed on the connector 101 facilitates the threaded connection between the connector 101 and the target probe 201. Thus, the target probe 201 can be designed to be mounted to a standard specification on the connector 101, and the axial position of the target probe 201 can be adjusted through the connector 101. This also helps to further reduce the production cost of the shaft vibration probe.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The mounting fixture for the shaft vibration probe also includes a pipe connector 113 connected to the first connector 102. The pipe connector 113 forms a mounting hole 114 through which the wiring conduit 101 passes and for connecting a protective pipe. According to the structure provided in this embodiment, the mounting hole 114 on the formed pipe connector 113 can provide protection for the wiring conduit 101 by connecting it to the protective pipe, which can significantly extend the service life of the mounting fixture for the shaft vibration probe in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The tooling structure for mounting the shaft vibration probe also includes a first fastening nut 115 threaded to the first connector 102, a second fastening nut 116 threaded to the pipe connector 113, and a third fastening nut 117 for axially tightening the first fastening nut 115 and the second fastening nut 116; the pipe connector 113 is detachably connected to the first connector 102 via the first fastening nut 115, the second fastening nut 116 and the third fastening nut 117. According to the structure provided in this embodiment, the second fastening nut 116 has an outer flange on its outer circumference near the end of the first fastening nut 115, and the third fastening nut 117 has an inner flange that matches the outer flange and an inner thread that matches the outer thread on the first fastening nut 115. Thus, after the third fastening nut 117 is movably fitted onto the second fastening nut 116, its inner thread engages with the outer thread on the first fastening nut 115. The inner flange on the third fastening nut 117 drives the outer flange on the second fastening nut 116, causing the second fastening nut 116 to abut and tighten against the first fastening nut 115. The pipe connector 113 is threadedly connected to the second fastening nut 116; thus, the pipe connector 113 can be easily and quickly installed on the first connector 102 through the first fastening nut 115, the second fastening nut 116, and the third fastening nut 117, without affecting the already adjusted wiring pipe 101; as a further preferred embodiment, the threads between the pipe connector 113 and the second fastening nut 116, and between the first fastening nut 115 and the first connector 102, adopt a pipe thread structure, which significantly reduces the installation difficulty of the tooling structure for installing the shaft vibration probe in this embodiment.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
