Description

Technical Field

[0001] This utility model relates to the field of industrial equipment condition monitoring technology, specifically a fault monitoring device for floating oil seal production equipment. Background Technology

[0002] Floating oil seals are an important component widely used in mechanical seals. With the expansion of production scale and the increase in the service life of floating oil seal production equipment, they face many failure problems, which not only affect production efficiency but may also lead to substandard product quality and economic losses. At present, vibration signal monitoring technology has become the mainstream method for the maintenance of floating oil seal production equipment due to its non-invasiveness, real-time performance and early fault warning capabilities.

[0003] In existing technologies, multiple vibration sensors are installed on floating oil seal production equipment to monitor vibration signals. These vibration sensors are divided into wired and wireless types. Compared to wired sensors, wired vibration sensors are cheaper, transmit data more stably, and require less technical expertise, thus making them more widely used. However, when multiple wired vibration sensors are used on a floating oil seal production equipment, their cables are scattered on the ground, which are not only easily tangled and damaged by being stepped on, but may also cause electromagnetic coupling, affecting the quality of vibration signal acquisition and monitoring. Therefore, a fault monitoring device for floating oil seal production equipment is proposed to solve the above problems. Utility Model Content

[0012] In one embodiment, a U-shaped bracket is fixed on either side of the support plate for fixing the vibration sensor.

[0013] In one embodiment, the stop block is composed of a blocking block and a toggle piece, and is an integrally formed structure. The blocking block contacts the outer peripheral wall of the blocking and limiting disk, and the blocking block is rotatably mounted on a support plate near the blocking and limiting disk via the rotating shaft.

[0020] Floating oil seals are an important component widely used in mechanical seals. With the expansion of production scale and the increase in the service life of floating oil seal production equipment, they face many failure problems, which not only affect production efficiency but may also lead to substandard product quality and economic losses. At present, vibration signal monitoring technology has become the mainstream method for the maintenance of floating oil seal production equipment due to its non-invasiveness, real-time performance and early fault warning capabilities.

[0021] In existing technologies, multiple vibration sensors are installed on floating oil seal production equipment to monitor vibration signals. These vibration sensors are divided into wired and wireless vibration sensors. Compared to wireless sensors, wired vibration sensors are cheaper, transmit data more stably, and require less reliance on technical personnel, thus they are more widely used. However, when multiple wired vibration sensors are used on floating oil seal production equipment, their cables are scattered on the ground, which are not only easy to get tangled and trampled on, but may also cause electromagnetic coupling, affecting the quality of vibration signal acquisition and monitoring.

[0022] Therefore, a fault monitoring device for floating oil seal production equipment is proposed to solve the above problems.

[0023] Please see Figure 1-3 The fault monitoring device for a floating oil seal production equipment in this embodiment includes at least one vibration sensor 1, a cable gathering mechanism, a fixing mechanism, and a collector 3. The cable gathering mechanism includes a cable 2 connected to the vibration sensor 1, a take-up and undo roller 9, and a spring 12. The spring 12 is used to drive the take-up and undo roller 9 to wind the cable 2 back to its original position after the cable 2 is pulled out. The fixing mechanism is used to prevent the cable 2 from winding back to its original position after the cable 2 is pulled out. The collector 3 has multiple connectors, and the cable 2 connector is connected to one of the collector 3 connectors.

[0024] Specifically, after cable 2 is pulled out and released, the spring 12 itself has a restoring force that drives the take-up and release roller 9 to rotate in the opposite direction, so that cable 2 can be automatically wound and retracted. At this time, the fixing mechanism can restrict the moving take-up and release roller 9 to prevent it from rotating in the opposite direction and driving cable 2 to be retracted, so as to achieve the stretching of cable 2 to any length. This allows the vibration sensor 1 to be used with floating oil seal production equipment, avoids excessive winding between multiple cables 2, and prevents electromagnetic coupling phenomenon, thus ensuring the quality of vibration signal acquisition and monitoring by the vibration sensor 1.

[0025] Among them, the vibration sensor 1 has magnetic and threaded connection types, which can be adapted to the actual use of floating oil seal production equipment.

[0026] It should be noted that the floating oil seal production equipment includes injection molding machines, molding machines, and testing equipment, and the vibration sensor 1 is a major monitoring method in the floating oil seal production equipment and is a known public knowledge.

[0027] In this embodiment, the cable gathering mechanism also includes a cable management assembly, two support plates 4 and multiple support rods 5. Multiple support rods 5 are fixed between the two support plates 4. One support plate 4 is rotatably connected to one end of the take-up and undo roller 9. A limit ring 11 is fixed on one side of the other support plate 4. An adjustment shaft 10 is fixed on the other end of the take-up and undo roller 9. The inner end of the spring 12 is engaged in the adjustment shaft 10, and the outer end of the spring 12 is engaged in the limit ring 11. The cable 2 is wound and fixed on the outer peripheral wall of the take-up and undo roller 9.

[0028] Specifically, when the cable 2 on one side of the vibration sensor 1 is pulled to the right, it causes the take-up and release roller 9 to rotate due to friction. This rotation, along with the adjustment shaft 10, causes the inner end of the spring 12 to be tensioned and stored around the periphery. When the pulling force of the cable 2 disappears, the tension of the spring 12 is released. Under this force, the spring 12 returns to its original position, and the adjustment shaft 10 causes the take-up and release roller 9 to return to its original position, thus realizing the rotation and winding of the cable 2.

[0029] Both the adjusting shaft 10 and the limiting ring 11 have notches to facilitate the installation of the spring 12.

[0030] In this embodiment, the cable management assembly includes a drive gear 13 and a reciprocating screw 6. The reciprocating screw 6 is rotatably mounted between two support plates 4. The drive gear 13 is fixed on the adjusting shaft 10. A transmission gear 7 that meshes with the drive gear 13 is fixed on the reciprocating screw 6. A cable management frame 8 with one end slidably sleeved on an adjacent support rod 5 is also threaded onto the reciprocating screw 6.

[0031] Specifically, when the spring 12 drives the take-up and untake-down rollers 9 to rotate in the forward and reverse directions, the drive gear 13 drives the transmission gear 7 to rotate, thereby rotating the reciprocating screw 6. This allows the cable organizer 8, which is limited and slidable by the support rod 5, to move back and forth on the reciprocating screw 6, thus driving the cable 2 to be neatly wound and avoiding the situation where messy winding damages the cable 2.

[0032] In this embodiment, the fixing mechanism includes a blocking and limiting plate 14 and a U-shaped positioning piece 16. The blocking and limiting plate 14 is fixed to the rear end of the outer peripheral wall of the take-up and untake-down roller 9 and is located on the rear side of the cable 2. The U-shaped positioning piece 16 is fixed on the bearing plate 4 near the blocking and limiting plate 14. A triangular lever 17 extending above and contacting the lower end of the U-shaped positioning piece 16 is fixed. A right-angled triangular block 18 is fixedly installed below the triangular lever 17. A slot 15 adapted to the right-angled triangular block 18 is opened on the outer peripheral wall of the blocking and limiting plate 14.

[0033] Specifically, when the cable 2 on one side of the vibration sensor 1 is pulled to the right, the take-up and release roller 9 drives the blocking and limiting disk 14 to rotate, causing the inclined surface of the outer peripheral wall slot 15 to move along the inclined surface of the right-angled triangular block 18. Since the triangular lever 17 is not connected to the bearing plate 4, the right-angled triangular block 18 is driven by force to cause the triangular lever 17 to deform slightly. The right-angled triangular block 18 can slide into the other slot 15 through the inclined surface, realizing the reset and fixation of the take-up and release roller 9. When the take-up and release roller 9 drives the blocking and limiting disk 14 to rotate in the opposite direction, the right-angled triangular block 18 is blocked by the vertical surface of the slot 15, so that the blocking and limiting disk 14 does not move, thus avoiding the take-up and release roller 9 from driving the cable 2 to reset, realizing the adjustable length of the cable 2.

[0034] It should be understood that when cable 2 needs to be stored, the tip of the triangular lever 17 can be lifted upwards, so that the right-angled triangular block 18 disengages from the slot 15 and no longer limits the obstruction limit plate 14, allowing the take-up and release roller 9 to store cable 2.

[0035] In addition, the right-angled triangular block 18, the triangular lever 17, and the U-shaped positioning piece 16 are all made of elastic metal material with constant elasticity alloy, which has elasticity and sufficiently high strength. They can be selected according to the actual use situation.

[0036] In this embodiment, the cable management frame 8 is used to drive the cable 2 to be evenly wound around the outer periphery of the take-up and unwinding roller 9.

[0037] Among them, the cable management frame 8 can drive the cable 2 to move back and forth, thereby realizing the overall winding of the cable 2, making the cable 2 neat and avoiding messy tangling and damage.

[0038] In this embodiment, a U-shaped bracket 22 is fixed on either side of the support plate 4 for fixing the vibration sensor 1.

[0039] Specifically, the two ends of the U-shaped bracket 22 are fixed with protrusions that are in contact with the vibration sensor 1. When the vibration sensor 1 is inserted into it, the protrusions will restrain the vibration sensor 1.

[0040] It should be noted that the vibration sensor 1 is fixed to the U-shaped bracket 22, which allows the cable 2 to be stored through the cable management mechanism when the vibration sensor 1 is not in use, and the vibration sensor 1 can also be stored at the same time.

[0041] Based on the above embodiments, this utility model also provides a technical solution: Please refer to... Figure 4-6 In this embodiment, the fixing mechanism includes a blocking and limiting plate 14, a stop block 20, and a rotating shaft 19. The blocking and limiting plate 14 is fixed to the rear end of the outer peripheral wall of the take-up and unwinding roller 9 and is located on the rear side of the cable 2. The stop block 20 is rotatably mounted on the support plate 4 near the blocking and limiting plate 14 via the rotating shaft 19. The stop block 20 contacts the outer peripheral wall of the blocking and limiting plate 14. A torsion spring 21 is sleeved on the outside of the rotating shaft 19, with one end connected to the support plate 4 and the other end connected to the stop block 20. The stop block 20 is composed of a blocking block and a toggle piece and is an integrally formed structure. The blocking block contacts the outer peripheral wall of the blocking and limiting plate 14 and is rotatably mounted on the support plate 4 near the blocking and limiting plate 14 via the rotating shaft 19.

[0042] Specifically, pressing the actuating piece 20 causes the actuating piece 20 to rotate to the left around the pivot 19, moving away from the blocking limit plate 14. At this time, when the cable 2 on one side of the vibration sensor 1 is pulled to the right, the take-up and release roller 9 drives the blocking limit plate 14 to rotate. After pulling out the cable 2 of the required length, the actuating piece can be released, and the torsion spring 21 drives the block to reset and press against the blocking limit plate 14 to prevent it from rotating. When the vibration sensor 1 is not in use, the actuating piece can be adjusted again to make the spring 12 drive the take-up and release roller 9 to reset.

[0043] In addition, the one-piece molded structure of the actuation block 20 makes the actuation plate stronger during use, less prone to cracking, fatigue resistant, and extends its service life.

[0044] It should be noted that a thick rubber sheet is embedded on the stop block 20, which increases the friction between the stop block 20 and the blocking limit plate 14. The spring force of the torsion spring 21 and the friction force together resist the restoring force of the spring spring 12, making the length adjustment of the cable 2 more stable.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
