[0016] The present invention provides a train rotating part fault detection device that is easy to disassemble and assemble, and has the following beneficial effects:

[0017] 1. The train rotating part fault detection device which is easy to disassemble and assemble can drive the rack 1 and the rack 2 meshing with the driving gear to move in opposite directions in the upper and lower positions inside the built-in track through the rotation of the driving gear. The upper limit frame and the lower limit frame which are engaged with the rack 1 and the rack 2 can be followed by movement. The upper limit frame and the lower limit frame can follow the movement to resist the outside of the required fault detection area, so that the entire fault detection device can quickly fix the external installation area of ​​the motor rotating part. Similarly, according to the environment in which the train motor rotating part is located, when it is necessary to clamp the fault detection device about the train motor rotating part for detection, the driving gear is rotated in the opposite direction through the design of the servo motor, so that the rack 1 and the rack 2 will approach the servo motor area, so that the upper limit frame and the lower limit frame are close to each other, and can be resisted and fixed or clamped and fixed according to the environment in which the train motor rotating part is located.

[0018] 2. The train rotating parts fault detection device, which is easy to disassemble and assemble, uses a laser displacement sensor to directly measure the vibration amplitude and frequency of the motor housing, and uses an acquisition card to record the displacement of the motor during the entire vibration process, so as to perform fault analysis and detection on the train motor rotating parts. After the fault detection, the servo motor design can be used to actively rotate the gears again, so that rack one and rack two rotate in opposite directions, so as to control the distance between the upper limit frame and the lower limit frame, so as to facilitate the rapid separation of the entire fault detection device from the train rotating parts area.

[0019] 3. The train rotating part fault detection device which is easy to disassemble and assemble is conducive to adjusting the extension position of the adjustment plate according to the external environment in which the train rotating part is located, through the design of the adjustment component, and is conducive to adaptive installation and fixation of the fault detection device according to the environment in which the train rotating part is located during fault detection.

[0020] 4. The train rotating part fault detection device that is easy to disassemble and assemble can drive the extension frame to move through the design of the electric push rod. The extension frame can be easily used and stored through the movement of the extension frame. When the laser displacement sensor is stored toward the extension frame, the design of the side rod, the adapter plate and the connecting rod allows the built-in column to slide inside the external tube, so that the lubricating oil pre-stored in the external tube can drip from the bottom of the support plate to the adsorption cotton on the outer surface of the gear through the pressure applied by the built-in column. The rotation of the gear can drive rack 1 and rack 2 that are meshed with the driving gear to move in opposite directions in the upper and lower positions inside the built-in channel. When rack 1 and rack 2 move to the bottom of the support plate, the gear and the adsorption cotton will rotate with the built-in shaft, so that the gear and adsorption cotton adsorbed with lubricating oil will continuously contact rack 1 and rack 2, so as to evenly apply the lubricating oil to rack 1 and rack 2, which is conducive to keeping rack 1 and rack 2 meshing with the driving gear smoothly, and avoiding jamming of rack 1 and rack 2 meshing with the driving gear after long-term use, which affects the use.

DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1-Figure 7As shown, the present invention provides a technical solution: a train rotating part fault detection device that is easy to disassemble and assemble, including a support plate 1, an internal track 2, a driving component 3, a connecting rod 301, an installation shell 302, a servo motor 303, a mounting plate 4, a rack 1 5, an upper limit frame 6, an auxiliary frame 7, a rack 2 8, a lower limit frame 9, a storage auxiliary cover 10, a cleaning cotton wipe 11, a mounting column 12, an adjustment component 13, an adjustment plate 1301, a threaded rod 1302, a connecting handle 1303, an electric push rod 14, an extension frame 15, an auxiliary component 16, a built-in bottom frame 1601, a roller 1602, a cleaning brush 1603, a laser displacement sensor 17, a built-in slot 18, a fixing bolt 19, a driving gear 20, a side rod 21, an adapter plate 22, and a connecting rod. Rod 23, built-in column 24, external tube 25, built-in shaft 26, gear 27 and adsorption cotton 28, built-in channels 2 are opened on both sides of the interior of the support plate 1, and a group of built-in channels 2 are slidably installed with a rack 5 inside, and the rack 5 and the rack 28 are meshed and installed on both sides of the driving gear 20, and the lengths of the rack 5 and the rack 28 are the same. A side rod 21 is arranged on one side of the outer surface of the extension frame 15, and a connecting rod 23 is installed at the bottom of the side rod 21, and a built-in column 24 is arranged on the outer surface of the connecting rod 23, and a built-in column 24 is installed at the end of the built-in column 24, and an external tube 25 is arranged on the outside of the built-in column 24, and the end of the external tube 25 is connected to the middle part of the bottom of the support plate 1, and a gear 27 is arranged below the middle part of the bottom of the support plate 1, and the gear 27 Built-in shafts 26 are installed on both sides, and adsorption cotton 28 is arranged on the outer surface of the built-in shafts 26. The design of the electric push rod 14 can drive the extension frame 15 to move. The movement of the extension frame 15 facilitates the use and storage of the laser displacement sensor 17 stored inside the extension frame 15. When the laser displacement sensor 17 is stored inside the extension frame 15, the design of the side rods 21, the adapter plate 22 and the connecting rod 23 allows the built-in column 24 to slide inside the external tube 25, so that the lubricating oil pre-stored in the external tube 25 can drip from the bottom of the support plate 1 to the adsorption cotton 28 on the outer surface of the gear 27 through the pressure applied by the built-in column 24. At the same time, the rotation of the driving gear 20 can drive the driving gear 20 to rotate. The meshing rack 1 5 and rack 2 8 move in opposite directions in the upper and lower positions inside the built-in track 2. When the rack 1 5 and rack 2 8 move to the bottom of the support plate 1, the gear 27 and the adsorption cotton 28 will rotate with the built-in shaft 26, so that the gear 27 and the adsorption cotton 28 adsorbed with lubricating oil will continuously contact with the rack 1 5 and rack 2 8, so as to achieve uniform application of the lubricating oil to the rack 1 5 and rack 2 8, which is conducive to the smooth meshing of the rack 1 5 and rack 2 8 with the driving gear 20, and avoids the meshing of the rack 1 5 and rack 2 8 with the driving gear 20 after long-term use, which affects the use. Another set of built-in tracks 2 is internally slidingly provided with a rack 2 8, and a driving component 3 for assisting the drive disassembly and assembly is provided between the rack 1 5 and rack 2 8.The driving component 3 includes a connecting rod 301, a mounting housing 302 and a servo motor 303. The mounting housing 302 is provided at the end of the connecting rod 301. Mounting plates 4 are installed on both sides of the end of the connecting rod 301, and the mounting plate 4 and the connecting rod 301 form an "L"-shaped structure. The servo motor 303 is installed in the middle of the mounting housing 302. A driving shaft is installed at the output end of the servo motor 303 with a driving gear 20. A mounting column 12 is snap-fitted on one side of the outer surface of the first rack 5, and an upper limit frame 6 is installed at the end of the mounting column 12. The upper limit frame 6 and the lower limit frame 9 have exactly the same structure. A storage auxiliary cover 10 is provided on one side of the outer surfaces of the upper limit frame 6 and the lower limit frame 9. The storage auxiliary cover 10 is in a "C"-shaped structure, and the width of the storage auxiliary cover 10 is greater than the width of the support plate 1. And the storage auxiliary cover 10 is located on the upper and lower sides outside the support plate 1. A cleaning cotton swab 11 is installed at the bottom of the outer surfaces of the upper limit frame 6 and the lower limit frame 9 away from the storage auxiliary cover 10, and the cleaning cotton swab 11 is snap-fitted with the upper limit frame 6. By the position movement of the upper limit frame 6 and the lower limit frame 9 with respect to the support plate 1, when the servo motor 303 is not needed, by the mutual approach between the upper limit frame 6 and the lower limit frame 9, the storage auxiliary cover 10 on one side of the upper limit frame 6 and the lower limit frame 9 can be used to store the servo motor 303 from two upper and lower directions. At the same time, during this process, the design of the cleaning cotton swab 11 can be used to clean the ventilation port area of the servo motor 303 before storage. The lower limit frame 9 is snap-fitted on one side of the outer surface of the second rack 8. The support plate 1 is placed in the outer area of the train rotating part, that is, the motor shaft. Through the design of the servo motor 303, the driving gear 20 can be driven to rotate. By the rotation of the driving gear 20, the first rack 5 and the second rack 8 meshing with the driving gear 20 can be driven to move in opposite directions at the upper and lower positions inside the built-in track 2. By the position movement of the first rack 5 and the second rack 8, the upper limit frame 6 and the lower limit frame 9 snap-fitted with the first rack 5 and the second rack 8 can be followed. By following the upper limit frame 6 and the lower limit frame 9, the outside of the area where the fault detection is required can be resisted, so that the entire fault detection device can quickly fix the external installation area of the motor rotating part. In addition, according to the environment where the train motor rotating part is located, when it is necessary to detect the fault detection device after clamping it with respect to the train motor rotating part, the driving gear 20 can be rotated in the reverse direction through the design of the servo motor 303. As a result, the first rack 5 and the second rack 8 will approach the servo motor 303 area, and thus the upper limit frame 6 and the lower limit frame 9 will approach each other, and it can be fixed by resisting or clamping according to the environment where the train motor rotating part is located.

[0031] Such as Figure 1 , Figure 5 and Figure 6As shown, an auxiliary frame 7 is provided on one side of the top outer surface of the support plate 1, and an electric push rod 14 is installed inside the auxiliary frame 7, and an auxiliary component 16 for assisting in the storage and cleaning of the laser displacement sensor 17 is provided at the bottom of the auxiliary frame 7, and the auxiliary component 16 includes a built-in bottom frame 1601, a roller 1602 and a cleaning brush 1603, and the roller 1602 is rotatably installed inside the built-in bottom frame 1601, and the cleaning brush 1603 is distributed in an annular manner on the outer surface of the roller 1602, and a laser displacement sensor 17 is provided above the cleaning brush 1603, and the height of the laser displacement sensor 17 is less than the height of the built-in groove 18. Through the design of the electric push rod 14, after fault detection, when the extension frame 15 is stored inside the auxiliary frame 7, the laser displacement sensor 17 will contact the cleaning brush 1603 inside the built-in bottom frame 1601, thereby realizing the cleaning of the outer surface of the laser displacement sensor 17, which is convenient for the detection of the next group of train motor rotating parts. An extension frame 15 is provided at the output end, and a built-in groove 18 is provided inside the extension frame 15. A laser displacement sensor 17 is installed inside the built-in groove 18 through a fixing bolt 19. After the entire support plate 1 is fixedly installed on the outside of the train rotating part, the extension frame 15 can be driven to move through the design of the electric push rod 14. The laser displacement sensor 17 located inside the extension frame 15 is located above the train motor rotating part through the movement of the extension frame 15. The vibration amplitude and frequency of the motor housing are directly measured by the laser displacement sensor 17, and the displacement of the motor during the entire vibration process is recorded by the acquisition card, so as to perform fault analysis and detection on the train motor rotating part. After the fault detection, the active gear 20 can be rotated again through the design of the servo motor 303, so that the rack 1 5 and the rack 2 8 rotate in the opposite direction, so as to control the distance between the upper limit frame 6 and the lower limit frame 9, so as to facilitate the rapid separation of the entire fault detection device from the train rotating part area.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an adjustment component 13 for performing a second-degree position adjustment is arranged inside the upper limit frame 6 and the lower limit frame 9, and the adjustment component 13 includes an adjustment plate 1301, a threaded rod 1302 and a connecting handle 1303. The threaded rod 1302 is installed on the internal thread of the adjustment plate 1301, and the connecting handle 1303 is arranged on the bottom of the threaded rod 1302. The threaded rod 1302 is threadedly installed inside the upper limit frame 6 or the lower limit frame 9, and the adjustment plate 1301 is slidably arranged inside the upper limit frame 6 or the lower limit frame 9. The user manipulates the connecting handle 1303 clockwise or counterclockwise to rotate the threaded rod 1302, so that the adjustment plate 1301 on the outer surface of the threaded rod 1302 can move up or down inside the upper limit frame 6 or the lower limit frame 9, which is beneficial for adjusting the extended position of the adjustment plate 1301 according to the external environment of the train rotating part, and is beneficial for the fault detection device to be adaptively installed and fixed according to the environment of the train rotating part during fault detection.

[0033] In summary, if Figure 1-Figure 7As shown, the train rotating part fault detection device which is easy to disassemble and assemble, when in use, the support plate 1 is placed on the train rotating part, that is, the outer area of ​​the motor shaft, and the design of the servo motor 303 can drive the driving gear 20 to rotate. Through the rotation of the driving gear 20, the rack 1 5 and the rack 2 8 meshing with the driving gear 20 can be driven to move in opposite directions in the upper and lower positions inside the built-in track 2. Through the position movement of the rack 1 5 and the rack 2 8, the upper limit frame 6 and the lower limit frame 9 engaged with the rack 1 5 and the rack 2 8 can be followed. Through the follow-up of the upper limit frame 6 and the lower limit frame 9, the outside of the required fault detection area can be pressed, so that the entire fault detection device can quickly fix the external installation area of ​​the motor rotating part, and can also be adjusted according to the position of the train motor. The environment where the rotating part is located, when it is necessary to detect the fault detection device after clamping the rotating part of the train motor, the driving gear 20 is rotated in the opposite direction through the design of the servo motor 303, so that the rack 1 5 and the rack 2 8 will be close to the servo motor 303 area, so that the upper limit frame 6 and the lower limit frame 9 are close to each other, and can be supported and fixed or clamped and fixed according to the environment where the rotating part of the train motor is located. After the entire support plate 1 is fixedly installed on the outside of the train rotating part, the extension frame 15 can be driven to move through the design of the electric push rod 14. The position of the extension frame 15 is moved so that the laser displacement sensor 17 located inside the extension frame 15 is above the rotating part of the train motor, and the vibration amplitude of the motor housing is directly measured by the laser displacement sensor 17. The displacement of the motor during the entire vibration process is recorded with an acquisition card, so as to perform fault analysis and detection on the train motor rotating parts. After the fault detection, the servo motor 303 is designed to drive the gear 20 to rotate again, so that the rack 1 5 and the rack 2 8 rotate in the opposite direction, so as to control the distance between the upper limit frame 6 and the lower limit frame 9, so as to facilitate the rapid separation of the entire fault detection device from the train rotating parts area. The electric push rod 14 is designed to enable the laser displacement sensor 17 to contact the cleaning brush 1603 inside the built-in bottom frame 1601 when the extension frame 15 is stored inside the auxiliary frame 7 after the fault detection, so as to clean the outer surface of the laser displacement sensor 17, so as to facilitate the next group of train motor rotating parts detection. Secondly, the design of the electric push rod 14 can drive the extension frame 15 to move, and the movement of the extension frame 15 facilitates the use and storage of the laser displacement sensor 17 stored inside the extension frame 15. When the laser displacement sensor 17 is stored inside the extension frame 15, the design of the side rod 21, the adapter plate 22 and the connecting rod 23 allows the built-in column 24 to slide inside the external tube 25, so that the lubricating oil pre-stored in the external tube 25 can drip from the bottom of the support plate 1 to the adsorption cotton 28 on the outer surface of the gear 27 through the pressure applied by the built-in column 24. At the same time, through the rotation of the driving gear 20, the rack 1 5 and the rack 2 8 meshing with the driving gear 20 can be driven to move in opposite directions in the upper and lower positions inside the built-in channel 2.When the rack 15 and the rack 28 are moved to the bottom of the support plate 1, the gear 27 and the adsorption cotton 28 will rotate with the built-in shaft 26, so that the gear 27 and the adsorption cotton 28 adsorbed with lubricating oil will continuously contact the rack 15 and the rack 28, so as to achieve uniform application of lubricating oil to the rack 15 and the rack 28, which is conducive to the smooth meshing of the rack 15 and the rack 28 with the driving gear 20, and avoids the meshing of the rack 15 and the rack 28 with the driving gear 20 after long-term use, which affects the use.

Many modifications and variations will be apparent to those of ordinary skill in the art.
