Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment fault detection technology, and in particular to a fault detection device for rotating equipment. Background Technology

[0002] Rotating equipment is widely used in industrial production, energy and power, transportation and aerospace fields, such as motors, fans, pumps, compressors and turbines. During long-term operation, these devices are prone to imbalance, misalignment, bearing damage, loosening or resonance due to manufacturing errors, improper assembly, wear and aging or changes in external load, which can lead to abnormal vibration. If these problems are not detected and dealt with in time, they may affect the operating efficiency and product quality, or even cause equipment damage or safety accidents.

[0003] Currently, fault detection of rotating equipment mainly relies on vibration monitoring technology. Traditional methods typically use wired accelerometers or vibration sensors, which are installed on the surface of the equipment housing by bolts or adhesive to collect vibration signals during operation. Fault diagnosis is then performed by combining spectrum analysis and time-domain feature extraction. However, this type of installation method has problems such as cumbersome operation and inconvenient disassembly and assembly, and its efficiency is low, especially in scenarios that require rapid inspection or multi-point testing. Summary of the Invention

[0004] In view of this, the present invention provides a rotating equipment fault detection device, which can solve the shortcomings of traditional wired vibration sensor installation methods, such as cumbersome operation, inconvenient disassembly and assembly, difficulty in meeting the needs of rapid inspection or multi-point rotational testing, resulting in low fault detection efficiency.

[0005] The technical solution of this utility model is as follows: a rotating equipment fault detection device, including a fixing block, a spring, a mounting platform, a vibration sensor, a connecting belt, a connecting block, a magnetic plate, and an electric suction cup. Springs are installed on both fixing blocks, and the mounting platform is connected between the ends of the springs. A vibration sensor is installed on the mounting platform. A connecting belt is connected between the two fixing blocks. The connecting belt is used to conform to the outer surface of the rotating equipment for deformation. Connecting blocks are symmetrically installed on the connecting belt. A magnetic plate and an electric suction cup are installed on the connecting blocks. The magnetic plate is used to fix the rotating equipment by magnetic attraction, and the electric suction cup is used to fix the rotating equipment by negative pressure attraction.

[0006] As a preferred technical solution of this utility model, it also includes a screw, a first threaded hole symmetrically opened on the connecting strip, a second threaded hole opened on the fixing block, and through holes symmetrically opened on the mounting platform. The screw is slidably installed in the through holes of the mounting platform, and the screw is used to screw into the first threaded hole and the second threaded hole to limit the mounting platform in the horizontal direction.

[0007] As a preferred technical solution of this utility model, it also includes a limiting block, which is connected to the screw and is used to press down on the installation platform for limiting.

[0008] As a preferred embodiment of this utility model, it also includes a pull ring, with the pull ring connected to the end of the screw, and the pull ring is used by the operator to operate the screw.

[0009] As a preferred technical solution of this utility model, it also includes a locking rod, a first locking groove symmetrically opened on the mounting platform, a second locking groove opened on the limiting block, and a locking rod slidably arranged between the mounting platform and the limiting block.

[0010] As a preferred technical solution of this utility model, the clamp rod is U-shaped, and the two ends of the U-shaped clamp rod are slidably inserted into the first slot of the installation platform and the second slot of the limiting block, respectively, for limiting the installation platform in the vertical direction.

[0011] The present invention has the following advantages: 1. The present invention integrates a magnetic plate and an electric suction cup on the connecting belt to form a dual adsorption structure, which can quickly and stably adsorb and fix the entire detection device on the outer surface of the rotating equipment without the need for bolt fastening or adhesive, which significantly simplifies the installation and disassembly process. It is particularly suitable for on-site inspection scenarios that require frequent changes of detection points or rotation testing of multiple devices, and greatly improves the efficiency of fault detection.

[0012] 2. This utility model effectively limits the horizontal and vertical displacement of the installation platform in the non-working state by setting a multi-directional limiting mechanism composed of a screw, a limiting block and a U-shaped clamp, preventing the vibration sensor from shifting position or the internal components from loosening due to spring deformation or external disturbance. This not only improves the structural stability of the device during transportation and storage, but also ensures that the sensor is in the preset detection position each time it is used, thus guaranteeing the consistency, accuracy and repeatability of fault detection data.

Detailed Implementation

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0019] Example: A fault detection device for rotating equipment, see below Figures 1-3 As shown, the device includes two fixing blocks 1, arranged side-by-side; it also includes springs 2, mounting platforms 3, vibration sensors 4, connecting straps 5, connecting blocks 6, magnetic plates 7, and electric suction cups 8. Springs 2 are installed on the front and rear sides of the top of the two fixing blocks 1. The mounting platform 3 connects the tops of the four springs 2. A vibration sensor 4 is installed in the middle of the top of the mounting platform 3, and the vibration sensor 4 has a built-in communication module for transmitting data to an external monitoring system. A connecting strap 5 connects the two fixing blocks 1, and the connecting strap 5 conforms to the surface of the rotating device for deformation. Four connecting blocks 6 are symmetrically installed on the bottom of the connecting strap 5. Magnetic plates 7 are installed on the bottom of the two outer connecting blocks 6, and the magnetic plates 7 are used to fix the device to the rotating device by magnetic attraction. Electric suction cups 8 are installed on the bottom of the two inner connecting blocks 6, and the electric suction cups 8 are used to fix the device to the rotating device by negative pressure attraction.

[0020] In use, first, wrap the connecting strap 5 around the outer circumference of the rotating equipment to be tested, so that the connecting strap 5 adheres to the surface of the equipment. Then, start the electric suction cup 8 to generate negative pressure adsorption, and rely on the magnetic force of the magnetic plate 7 to firmly fix the entire device to the rotating equipment. Afterwards, when the rotating equipment vibrates abnormally during operation, the rotating equipment will drive the vibration sensor 4 to vibrate through the connecting strap 5, the fixing block 1, the spring 2 and the mounting platform 3. The vibration sensor 4 will collect vibration signals in real time and transmit the data to the external monitoring system through the built-in communication module, thereby realizing early identification and warning of rotating equipment faults. Then, the operator can judge whether there are abnormalities or potential faults in the rotating equipment based on the vibration characteristics fed back by the monitoring system. After the rotating equipment completes the test, stop the rotating equipment, then turn off the electric suction cup 8, and remove the connecting belt 5 from the outer periphery of the rotating equipment after the test.

[0021] See Figure 1 and Figure 4As shown, it also includes a screw 10; the top of the connecting strip 5 has two first threaded holes 901 symmetrically opened on the left and right; the top of each of the two fixing blocks 1 has a second threaded hole 902; the top of the mounting platform 3 has two through holes 903 symmetrically opened on the left and right, and the first threaded hole 901, the second threaded hole 902 and the through hole 903 on the same side are on the same vertical line; the screw 10 is slidably installed in the two through holes 903 of the mounting platform 3, and the screw 10 is used to screw into the first threaded hole 901 and the second threaded hole 902 to limit the mounting platform 3 in the horizontal direction.

[0022] By setting the screw 10, when the device is not in use, the screw 10 can be passed through the through hole 903 of the mounting platform 3, screwed into the second threaded hole 902 of the fixing block 1 and the first threaded hole 901 of the connecting belt 5 in sequence to form a three-point linkage structure. This prevents the mounting platform 3 from shifting in the left and right directions due to the elastic deformation of the spring 2 or external disturbances, and ensures that the vibration sensor 4 is always in the preset detection position. This effectively improves the structural stability of the device during transportation, storage or non-working state, avoids the loosening or damage of internal components due to the shaking of the mounting platform 3, and provides a basis for quick reset and accurate alignment for the next use, ensuring the reliability and repeatability of fault detection.

[0023] See Figure 1 and Figure 4 As shown, it also includes a limit block 11; the upper sides of both screws 10 are connected to the limit block 11, and the limit block 11 is used to press down the top of the installation platform 3 for limiting.

[0024] By setting the limit block 11, the positioning stability of the installation platform 3 can be further enhanced. The limit block 11 is fixed to the upper end of the screw 10 and presses the top of the installation platform 3. When the screw 10 is tightened, it restricts the installation platform 3 from jumping upward, preventing the internal connection from loosening or the sensing element from being damaged, and further improving the overall reliability and service life of the device.

[0025] See Figure 1 and Figure 4 As shown, it also includes a pull ring 12; the top ends of both screws 10 are connected to pull rings 12, which are used by the operator to operate the screws 10.

[0026] By setting up the pull ring 12, the operator can easily rotate the screw 10 manually to achieve quick installation or removal. The pull ring 12 provides a good gripping force point, and the screw 10 can be screwed in or out without additional tools, improving on-site maintenance efficiency. It is especially suitable for working conditions where space is limited or the inspection position needs to be changed frequently.

[0027] See Figure 1 and Figure 4As shown, it also includes a locking rod 15; two first locking slots 13 are symmetrically opened on the left and right sides of the mounting platform 3; a second locking slot 14 is opened on the side of the two limiting blocks 11 that are far apart from each other; a locking rod 15 is slidably provided between the left side of the mounting platform 3 and the left limiting block 11, and a locking rod 15 is also slidably provided between the right side of the mounting platform 3 and the right limiting block 11. The locking rod 15 is U-shaped, and the two ends of the U-shaped locking rod 15 are slidably inserted into the first locking slot 13 of the mounting platform 3 and the second locking slot 14 of the limiting block 11, respectively, for limiting the mounting platform 3 in the vertical direction.

[0028] By setting the locking rod 15, a double safety limit can be formed on the mounting platform 3 in the vertical direction. When the screw 10 is tightened, after the two ends of the U-shaped locking rod 15 are respectively inserted into the first slot 13 of the mounting platform 3 and the second slot 14 of the limiting block 11, even if the screw 10 is accidentally loosened or the spring 2 is fatigued and deformed, the locking rod 15 can still prevent the mounting platform 3 from moving downward or upward, thereby protecting the vibration sensor 4 and the internal connection structure from impact damage, ensuring that the device can be quickly put into testing without recalibration when used next, improving overall reliability and maintenance convenience.
