Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the papermaking industry, the operational stability of paper machine rollers and the air supply system directly affects paper quality and production efficiency. Bearings, as key rotating components, have their vibration status as an important indicator of equipment health. To measure bearing faults, magnetic vibration sensors are used for data acquisition. These sensors are magnetically attached to the bearing housing surface, held for a short time, and then removed.

[0030] like Figure 1 As shown, Figure 1 This is a cross-sectional view of the loading and unloading fixture for a magnetic vibration sensor in an embodiment of this utility model. The technical solution of this application provides a loading and unloading fixture for a magnetic vibration sensor. The loading and unloading fixture includes a support part 1, a pickup part 3, and a locking member 4. The pickup part 3 is provided with a receiving space 31 for placing the magnetic vibration sensor. The magnetic vibration sensor has a magnetic surface that magnetically attracts the outside. At least a portion of the locking member 4 is located within the receiving space 31. The locking member 4 can move relative to the receiving space 31 to fix the magnetic vibration sensor to the pickup part 3.

[0031] In actual operation, the magnetic vibration sensor is placed in the receiving space 31 and pressed against the pickup unit 3 by the locking member 4, thus forming a fixed connection between the magnetic vibration sensor and the pickup unit 3. At this time, by operating the support member 1, the magnetic vibration sensor is brought close to the measuring surface. Under the action of magnetic force, the magnetic surface of the magnetic vibration sensor is fixed to the measuring surface. After maintaining this state for a short time to collect data, the magnetic vibration sensor can be removed by operating the support member 1. Throughout this process, the magnetic vibration sensor is always fixed in the pickup unit 3 by the locking member 4.

[0032] The loading and unloading fixture can be held by the measuring personnel, and the pickup unit 3 can replace the measuring personnel's hands to install and remove the magnetic vibration sensor, reducing safety risks.

[0033] In the example shown in the figure, in order to increase the ease of operation of the loading and unloading fixture for the magnetic vibration sensor, in one embodiment, the loading and unloading fixture for the magnetic vibration sensor further includes a drive assembly 2, which is connected to the pickup part 3 in a transmission manner. The drive assembly 2 can drive the pickup part 3 to move relative to the support part 1 in the pushing direction and the retraction direction.

[0034] In actual operation, it is only necessary to move the support unit close to the measuring surface, and then drive the pickup unit 3 to move in the pushing direction. The magnetic surface of the magnetic vibration sensor will then move closer to the measuring surface until the magnetic vibration sensor is magnetically connected to the measuring surface. After measurement, the pickup unit 3 is driven to move in the retraction direction, thereby driving the magnetic vibration sensor to detach from the measuring surface.

[0035] This approach optimizes the stability and convenience of the tooling used for installing or removing magnetic vibration sensors.

[0036] In a specific example, the support portion 1 includes a first rod portion 11 and a second rod portion 12. The first rod portion 11 is provided with a drive assembly 2, and the second rod portion 12 is provided with a pickup portion 3. The first rod portion 11 extends along a first direction y, and the second rod portion 12 extends along a second direction x. The first direction y and the second direction x are set at an acute angle, an obtuse angle, or a right angle. By adopting this method, the ease of operation of the mounting and dismounting fixture of the magnetic vibration sensor in this application can be improved, and the pickup portion 3 can be aligned with the measuring surface.

[0037] like Figure 1 and Figure 4 As shown, the first rod portion 11 has a first groove 110 extending in the same direction as the first rod portion 11. A drive rod 21 is disposed within the first groove 110, and the drive rod 21 can move back and forth relative to the first groove 110 along a first direction y. The second rod portion 12 has a second groove 120 extending along a second direction x, and the pickup portion 3 is slidably adapted to fit within the second groove 120. The direction of movement further away from the second groove 120 is the pushing direction, and the direction of movement deeper into the second groove 120 is the retraction direction.

[0038] The drive assembly 2 includes a drive rod 21 and a link assembly 22. The link assembly 22 includes a first link 221, a second link 222, and a third link 223 hinged at one end. The other end of the first link 221 is hinged to the drive rod 21. The other end of the second link 222 is hinged to the first link portion 222. The other end of the third link 223 is hinged to the pickup portion 3.

[0039] In this embodiment, the connecting rod assembly 22 constitutes a crank-connecting rod mechanism. When the drive rod 21 is driven to move upward along the first direction y, the first connecting rod 221 drives the second connecting rod 222, and drives the hinged ends of the first connecting rod 221, the second connecting rod 222, and the third connecting rod 223 to move. The third connecting rod 223 drives the pickup part 3 to move along the second slide groove 120 in the pushing direction and the retraction direction. The pushing direction is the direction of movement towards the outside of the second slide groove 120, and the retraction direction is the direction of movement towards the inside of the second slide groove 120.

[0040] In a more specific example, the first rod portion 11 is provided with a handheld end 112 for the measuring person to hold, and the second rod portion 12 is disposed along a first direction y on the side of the first rod portion 11 away from the handheld end 112. This allows it to be adapted to a measuring surface at a certain distance.

[0041] For example, the measuring surfaces of the roller bearings in a paper machine are usually distributed at different height levels of the equipment, requiring measuring personnel to use climbing tools to reach them. Similarly, the fan bearings of the air supply system adapted to the paper machine, and the drive roller bearings in the pit, are located in the pit, requiring measuring personnel to bend down or enter the pit to operate.

[0042] During this process, surveyors need to frequently adjust the position of climbing tools or enter and exit the pit, increasing the time for single-point measurement by more than 50%, making it difficult to meet the needs of rapid inspection on large-scale production lines. By adopting the loading and unloading fixture of the magnetic vibration sensor in this application, a certain height can be compensated for, reducing the need for surveyors to climb or enter and exit the pit, thereby reducing the time for single-point measurement and improving the measurement efficiency of surveyors in loading and unloading the magnetic vibration sensor.

[0043] In an optional example of this implementation, such as Figure 1 and Figure 2 As shown, the second rod portion 12 is disposed on the side of the first rod portion 11, and the end face of the first rod portion 11 is hinged to one end of the second connecting rod 222.

[0044] The top of the second rod portion 12 is also provided with a clearance channel 121, which penetrates the wall of the partial pickup portion 3 along the first direction and communicates with the second groove portion 120. The third connecting rod 223 can move within the second groove portion 120 and the clearance channel 121 and is hinged to the end face of the pickup portion 3. As a result, the size of the loading and unloading fixture in the first direction y and the second direction x can be reduced.

[0045] A support beam 13 is also provided between the second rod 12 and the first rod 11. This increases the structural strength of the support 1.

[0046] In the aforementioned embodiments, such as Figure 3As shown, the locking member 4 is threadedly fitted to the pickup part 3. The locking member 4 is a rod-shaped structure that passes through the wall of the pickup part 4, with one end located outside the receiving space 31 and partly located inside the receiving space 31. The end located outside the receiving space 31 serves as a driving end, and by operating the driving end, the locking member 4 can be moved toward or away from the receiving space 31.

[0047] After placing the magnetic vibration sensor in the receiving space 31, the operating drive end is used to drive the locking member 4 to press the magnetic vibration sensor. The pressing force of the locking member 4 on the magnetic vibration sensor is greater than the magnetic force of the magnetic vibration sensor, thereby allowing the magnetic vibration sensor to be removed by operating the support part 1.

[0048] To protect the magnetic vibration sensor, a pressure pad 41 is provided at one end of the locking member 3 located within the receiving space 31. The pressure pad 41 is elastic and can be made of materials such as rubber. To reduce the stress on the magnetic vibration sensor, the radial dimension of the pressure pad 41 is larger than the radial dimension of the locking member 3.

[0049] In other embodiments of this application, such as Figure 2 As shown, to facilitate wiring and improve the connection strength between the pickup unit 3 and the magnetic vibration sensor, the pickup unit 3 is also provided with a wiring channel 32. The locking member 4 is located at one end of the receiving space 31 along the first direction y, and the wiring channel 32 is located at the other end of the receiving space 31. The outer wall of the pickup unit 3 has an opening 311 that communicates with the receiving space 31, and the opening 311 is located on the side of the receiving space 31.

[0050] Combination Figure 1 and Figure 3 As shown, Figure 3 This is a cross-sectional view of the pickup unit 3, where z is a third direction perpendicular to the first direction y and the second direction x. One end of the pickup unit 3 along the second direction x is away from the first rod 11, and the other end is close to the first rod 11. An opening 311 is provided at the end of the pickup unit 3 away from the first rod 11. The magnetic sensor has a magnetically attached surface that is magnetically connected to the outside. The magnetically attached surface can be exposed through the opening 311 and adsorbed onto the measuring surface.

[0051] like Figure 3 As shown, the pickup unit 3 includes a support wall section 312 constituting a partial receiving space 31. The support wall section 312 is curved, and 32 wiring channels pass through it. The support wall section 312 is opposite to the locking member 4 along the first direction y and is used to fit against the wall surface of the magnetic vibration sensor. The wiring terminals of the magnetic vibration sensor can be located within the wiring channel 32.
