Description

Technical Field

[0001] This invention relates to the field of sleeper monitoring device technology, specifically a railway construction track sleeper stability monitoring device. Background Technology

[0002] Concrete sleepers are concrete products used as railway sleepers. They are made by mixing cement, sand, stone, water, and admixtures in a certain proportion, injecting the mixture into a modular mold containing steel wires or reinforcing bars and sleeper accessories, and then using vibration molding or load vibration molding, steam curing, loosening the steel wires or reinforcing bars, and cutting the sleeper ends. Concrete sleepers have advantages such as saving wood, long service life, good track laying quality, less maintenance, and low cost.

[0003] Currently, after installation, railway sleepers are usually equipped with monitoring devices to capture sleeper data and provide basic data for stability assessment. For example, Chinese patent CN220079596U discloses a stability monitoring device for ballasted track sleepers, which includes a sleeper body of ballasted track, a fiber optic grating sleeper monitoring system installed inside the sleeper body, and external monitoring equipment for analyzing the stability of ballasted track. The above device monitors sleeper strain, temperature and related pressure data by pre-embedding fiber optic grating smart ribs and smart sensors inside the sleeper, while also providing reinforcement without affecting the normal service of the sleeper.

[0004] However, the aforementioned devices cannot capture hidden damage and changes in the condition of sleepers through vibration characteristics and abnormal sounds, making it difficult for staff to fully grasp the stability of sleepers. Furthermore, the sensors are easily clogged or contaminated by dust, further affecting the accuracy of data collection and making it difficult to meet the needs for real-time and accurate monitoring of sleeper stability.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0006] To address the above problems, the present invention provides the following technical solution: A railway construction track sleeper stability monitoring device includes a mounting sleeve, on the back of which a concrete sleeper is fixedly mounted, and further includes: The self-cleaning monitoring component, installed on the mounting sleeve, is used for intelligent monitoring of concrete sleepers; The self-cleaning monitoring component includes a fixed sleeve fixedly connected to one side of the mounting sleeve, a motor fixedly connected to the bottom of the fixed sleeve, the output end of the motor penetrating into the interior of the fixed sleeve and fixedly connected to a screw, a transmission component being provided on the screw, a concave plate fixedly connected to one side of the fixed sleeve, a temperature and humidity sensor fixedly connected inside the concave plate, a PVC cylinder fixedly connected to the bottom of the temperature and humidity sensor, and a cleaning component connected to the transmission component being provided on the PVC cylinder; A monitoring and control device is fixedly installed on the mounting sleeve. A sound sensing device connected to the transmission component is installed inside the fixed sleeve. Four symmetrically arranged vibration sensors are fixedly installed inside the concrete sleeper. Backflush anti-clogging component, installed on one side of the PVC cylinder, is used to unclog and prevent blockage of the PVC cylinder.

[0007] Furthermore, the transmission component includes a threaded sleeve threaded onto a screw rod, two slide rods symmetrically fixedly connected to the threaded sleeve, a movable sleeve provided inside the fixed sleeve, two inclined openings symmetrically opened on the movable sleeve, and the slide rods slidably connected inside the inclined openings; A movable rod is fixedly connected to one side of the movable sleeve, and one end of the movable rod extends through to the outside of the fixed sleeve and is fixedly connected to a toothed plate.

[0008] Furthermore, the fixed sleeve has two baffles symmetrically fixedly connected inside, the bottom of the baffles contacting the top of the movable sleeve, and four limiting rods fixedly connected inside the fixed sleeve, with the threaded sleeve slidably sleeved on the limiting rods.

[0009] Furthermore, the cleaning assembly includes a toothed ring movably connected to a PVC cylinder via a bearing, the toothed ring meshing with a toothed plate, a spiral scraper fixedly connected to the bottom of the toothed ring, the inner wall of the spiral scraper contacting the surface of the PVC cylinder, and a support sleeve fixedly connected inside the concave plate, the support sleeve being fitted onto the toothed plate.

[0010] Furthermore, the monitoring and control device includes a top plate fixedly mounted on the mounting sleeve by bolts, a top sleeve fixedly connected to the top of the top plate, a data processing device fixedly connected inside the top sleeve, and an infrared sensor located on one side of the data processing device fixedly connected inside the top sleeve.

[0011] Furthermore, the sound sensing device includes a sound sensor fixedly connected to one side of the screw sleeve, the top of the sound sensor extending through to the top of the fixed sleeve and fixedly connected to an outer square sleeve, an inner square sleeve fixedly connected to the fixed sleeve, and the outer square sleeve fitted onto the inner square sleeve.

[0012] Furthermore, the backflush anti-clogging component includes a metal pipe connected to one side of the PVC cylinder, a corrugated sleeve is fixedly connected inside the fixed sleeve, one end of the corrugated sleeve is fixedly connected to the movable sleeve, one end of the metal pipe extends into the interior of the corrugated sleeve, a positioning plate is fixedly connected to the metal pipe, and one side of the positioning plate is fixedly connected to the temperature and humidity sensor.

[0013] Furthermore, the top sleeve is provided with a self-lifting protective component, which includes a transparent plate slidably connected inside the top sleeve. The bottom of the transparent plate extends through to the bottom of the top sleeve and is fixedly connected to a disc. A steel wire rope is fixedly connected to the bottom of the disc. The end of the steel wire rope away from the disc passes through the mounting sleeve and the fixed sleeve in sequence and is fixedly connected to the movable sleeve through a connecting plate. A spring is fixedly connected to the bottom of the disc, and the bottom end of the spring is fixedly connected to the mounting sleeve. Two rubber scrapers are symmetrically fixedly connected inside the mounting sleeve, and one side of the rubber scraper is in contact with the surface of the transparent plate.

[0014] Furthermore, a positioning tube is fixedly connected to the bottom of the disc, and the bottom end of the positioning tube extends into the interior of the mounting sleeve. A roller is hinged inside the mounting sleeve via a shaft, and the wire rope is looped on the roller.

[0015] Furthermore, a sealing ring one is fixedly connected to the top of the mounting sleeve, and the inner wall of the sealing ring one is in contact with the surface of the positioning tube. A sealing ring two is fixedly connected to one side of the fixing sleeve, and the inner wall of the sealing ring two is in contact with the surface of the moving rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by integrating multiple types of sensors, the environmental conditions, vibration characteristics and abnormal sounds of the sleeper are comprehensively captured, and real-time changes are accurately fed back, providing data support for stability assessment. At the same time, the sound sensing device is driven to rise and fall by the detection and control device and the transmission component, which simultaneously drives the cleaning component to clean the surface of the PVC cylinder. This makes it convenient to store and protect the cylinder after the train passes, and effectively avoids dust clogging the sensing components, ensuring monitoring accuracy. This achieves the coordinated operation of intelligent monitoring and automated cleaning, which is convenient for long-term accurate monitoring. 2. In this invention, although the spiral scraper can clean the surface of the PVC cylinder, it is difficult to clean the fine dust clogging inside the PVC cylinder. Long-term use may still leave pollutants, affecting the data acquisition accuracy of the temperature and humidity sensor. The back-flushing anti-clogging component, through the structural design of metal tube, positioning plate and corrugated sleeve, uses the movement of the moving sleeve to squeeze the corrugated sleeve, so that the air inside the corrugated sleeve is injected into the PVC cylinder through the metal tube. This can blow out the fine dust clogging the PVC cylinder in the opposite direction, achieving dual protection of mechanical cleaning and airflow back-flushing. This effectively avoids sensor failure caused by long-term dust accumulation and further ensures monitoring accuracy.

[0017] 3. In this invention, the data processing device and infrared sensor inside the top sleeve lack a targeted protective structure. Dust in the air adheres to the data processing device and infrared sensor, contaminating the sensing components and electronic parts. Long-term use can easily lead to the failure of monitoring and control functions. However, through the design of the transparent plate, disc, and steel wire rope in the self-lifting protective component, the transparent plate can effectively block dust and rainwater. When a train passes, the moving sleeve is linked to the steel wire rope to lower the transparent plate. After the train moves away, the spring drives the transparent plate to rise through the disc. In conjunction with the rubber scraper, the surface of the transparent plate is cleaned during the lifting process. This not only avoids dust from obstructing the infrared sensing effect but also achieves effective protection for the components. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the present invention provides a railway construction track sleeper stability monitoring device, including a mounting sleeve 1, on the back of which a concrete sleeper 2 is fixedly mounted, and further comprising: The self-cleaning monitoring component 3 is installed on the mounting sleeve 1 and is used for intelligent monitoring of the concrete sleeper 2. The self-cleaning monitoring component 3 includes a fixed sleeve 31 fixedly connected to one side of the mounting sleeve 1. A motor 32 is fixedly connected to the bottom of the fixed sleeve 31. The output end of the motor 32 passes through the interior of the fixed sleeve 31 and is fixedly connected to a screw 33. A transmission component 34 is provided on the screw 33. A concave plate 35 is fixedly connected to one side of the fixed sleeve 31. A temperature and humidity sensor 36 is fixedly connected inside the concave plate 35. A PVC cylinder 37 is fixedly connected to the bottom of the temperature and humidity sensor 36. A cleaning component 38 connected to the transmission component 34 is provided on the PVC cylinder 37. A monitoring and control device 39 is fixedly installed on the mounting sleeve 1. A sound sensing device 310 connected to the transmission component 34 is installed inside the fixed sleeve 31. Four symmetrically arranged vibration sensors are fixedly installed inside the concrete sleeper 2. Backflush anti-clogging component 4 is installed on one side of PVC cylinder 37 and is used to unclog and prevent blockage of PVC cylinder 37.

[0022] Specifically, the mounting sleeve 1 is fixedly installed on the concrete sleeper 2 with bolts. The motor 32 is a miniature waterproof motor. A stainless steel cylinder is fixedly connected to the bottom of the fixing sleeve 31. The stainless steel cylinder is fitted onto the motor 32 and can seal and protect the motor 32. The temperature and humidity sensor 36 is an industrial-grade temperature and humidity sensor. A PVC cylinder 37 is fitted onto the probe of the temperature and humidity sensor 36. The PVC cylinder 37 consists of a PVC round sleeve, a filter port, and a stainless steel filter screen. The filter port is opened on the PVC round sleeve, and the stainless steel filter screen is fixedly connected in the filter port. The stainless steel filter screen can filter impurities in the air.

[0023] like Figures 1 to 4 As shown, the transmission component 34 includes a threaded sleeve 341 threadedly connected to the screw 33, two slide rods 342 symmetrically fixedly connected to the threaded sleeve 341, a movable sleeve 343 is provided inside the fixed sleeve 31, two inclined openings 344 are symmetrically opened on the movable sleeve 343, and the slide rods 342 are slidably connected inside the inclined openings 344. A movable rod 345 is fixedly connected to one side of the movable sleeve 343. One end of the movable rod 345 extends through to the outside of the fixed sleeve 31 and is fixedly connected to a toothed plate 346.

[0024] Specifically, during use, the screw 33 drives the screw sleeve 341 to move. By utilizing the sliding engagement between the slide rod 342 and the inclined opening 344, the linear motion of the screw sleeve 341 is converted into the lateral displacement of the moving sleeve 343, which in turn drives the moving rod 345 and the toothed plate 346 to move smoothly. It can also synchronously link the cleaning component 38, the sound sensor 310 and the self-lifting protective component 7 to achieve the coordinated operation of multiple components.

[0025] like Figure 3 As shown, two baffles 5 are symmetrically fixedly connected inside the fixed sleeve 31. The bottom of the baffles 5 is in contact with the top of the movable sleeve 343. Four limiting rods 6 are fixedly connected inside the fixed sleeve 31. The screw sleeve 341 is slidably sleeved on the limiting rods 6.

[0026] Specifically, the baffle 5 can limit the movement of the movable sleeve 343 to prevent it from wobbling up and down during movement; the four limiting rods 6 can accurately guide the screw sleeve 341 to prevent it from shifting with the screw 33 and ensure the stability of linear transmission.

[0027] like Figures 2 to 5 As shown, the cleaning assembly 38 includes a toothed ring 381 movably connected to the PVC cylinder 37 via a bearing. The toothed ring 381 meshes with the toothed plate 346. A spiral scraper 382 is fixedly connected to the bottom of the toothed ring 381. The inner wall of the spiral scraper 382 is in contact with the surface of the PVC cylinder 37. A support sleeve 383 is fixedly connected inside the concave plate 35 and is sleeved on the toothed plate 346.

[0028] Specifically, the toothed ring 381 meshes with the toothed plate 346 to drive the spiral scraper 382 to rotate and scrape along the surface of the PVC cylinder 37, effectively removing dust and debris and preventing the PVC cylinder 37 from becoming clogged and unable to effectively detect temperature and humidity. The support sleeve 383 provides a stable guide for the toothed plate 346, ensuring precise and stable meshing and cleaning without manual intervention.

[0029] like Figures 2 to 4 As shown, the monitoring and control device 39 includes a top plate 391 fixedly mounted on the mounting sleeve 1 by bolts, a top sleeve 392 fixedly connected to the top of the top plate 391, a data processing device 393 fixedly connected inside the top sleeve 392, and an infrared sensor 394 located on one side of the data processing device 393 fixedly connected inside the top sleeve 392.

[0030] Specifically, the data processing device 393 can centrally integrate information collected by multiple types of sensors, analyze and process it, and send it to the monitoring center in real time to realize the remote transmission and centralized management of sleeper stability data; after the infrared sensor 394 detects a train, it can start the motor 32 through the external control device. The motor 32 rotates forward and drives the screw sleeve 341 to rise through the screw 33. When no train is detected, the external control device can control the motor 32 to reverse and drive the screw sleeve 341 to fall through the screw 33, providing a trigger signal for intelligent monitoring and automated cleaning linkage, so that staff can remotely monitor the sleeper status in real time.

[0031] like Figures 1 to 4 As shown, the sound sensing device 310 includes a sound sensor 3101 fixedly connected to one side of the screw sleeve 341. The top of the sound sensor 3101 extends through to the top of the fixed sleeve 31 and is fixedly connected to an outer square sleeve 3102. An inner square sleeve 3103 is fixedly connected to the fixed sleeve 31, and the outer square sleeve 3102 is fitted onto the inner square sleeve 3103.

[0032] Specifically, the bottom of the sound sensor 3101 is fixedly connected with a reinforcing rib, one side of which is fixedly connected to the threaded sleeve 341. The reinforcing rib can increase the connection strength between the sound sensor 3101 and the threaded sleeve 341. The sound sensor 3101 will rise and fall synchronously with the threaded sleeve 341. When a train passes, it rises to deploy for monitoring, and when there is no train, it falls down for storage and protection, effectively avoiding collisions and dust contamination. The outer square sleeve 3102 and the inner square sleeve 3103 are fitted together to achieve both lifting guidance and sealing protection, preventing impurities from seeping in and affecting the sensing accuracy. The sound sensor 3101 can accurately detect abnormal sounds from the sleeper.

[0033] like Figures 1 to 4 As shown, the backflush anti-clogging component 4 includes a metal pipe 41 connected to one side of the PVC cylinder 37, a corrugated sleeve 42 fixedly connected inside the fixed sleeve 31, one end of the corrugated sleeve 42 fixedly connected to the movable sleeve 343, one end of the metal pipe 41 penetrating into the interior of the corrugated sleeve 42, a positioning plate 43 fixedly connected to the metal pipe 41, and one side of the positioning plate 43 fixedly connected to the temperature and humidity sensor 36.

[0034] Specifically, the corrugated sleeve 42 is made of bend-resistant rubber material; when the movable sleeve 343 moves, it will squeeze the corrugated sleeve 42, so that the air inside the corrugated sleeve 42 is injected into the PVC cylinder 37 through the metal tube 41, which can blow out the fine dust blocking the PVC cylinder 37 in the opposite direction, realizing the dual protection of mechanical cleaning and airflow back blowing, effectively avoiding the sensor failure caused by long-term dust accumulation, and further ensuring the monitoring accuracy.

[0035] like Figures 4 to 6As shown, the top sleeve 392 is provided with a self-lifting protective component 7. The self-lifting protective component 7 includes a transparent plate 71 that is slidably connected inside the top sleeve 392. The bottom of the transparent plate 71 extends through to the bottom of the top sleeve 392 and is fixedly connected to a disc 72. The bottom of the disc 72 is fixedly connected to a steel wire rope 73. The end of the steel wire rope 73 away from the disc 72 passes through the mounting sleeve 1 and the fixed sleeve 31 in sequence and is fixedly connected to the movable sleeve 343 through a connecting plate. A spring 74 is fixedly connected to the bottom of the disc 72. The bottom end of the spring 74 is fixedly connected to the mounting sleeve 1. Two rubber scrapers 75 are symmetrically fixedly connected inside the fixing sleeve 31. One side of the rubber scraper 75 is in contact with the surface of the transparent plate 71.

[0036] Specifically, the transparent plate 71 is a transparent acrylic plate; the transparent plate 71 can effectively block dust and rainwater. When a train passes by, the moving sleeve 343 is linked to the steel wire rope 73 to drive the transparent plate 71 to descend. After the train moves away, the spring 74 drives the transparent plate 71 to rise through the disc 72. In conjunction with the rubber scraper 75, the surface of the transparent plate 71 is cleaned during the lifting and lowering process, which not only avoids dust from obstructing the infrared sensing effect, but also achieves effective protection of the components.

[0037] like Figure 4 As shown, a positioning tube 8 is fixedly connected to the bottom of the disc 72. The bottom end of the positioning tube 8 extends into the interior of the mounting sleeve 1. A roller 9 is hinged to the interior of the mounting sleeve 1 via a shaft. A wire rope 73 is sleeved on the roller 9.

[0038] Specifically, the positioning tube 8 can provide precise guidance for the lifting of the disc 72, avoid the transparent plate 71 from shifting or getting stuck, and ensure the smooth operation of the self-lifting protective component 7; the roller 9 can guide the wire rope 73, prevent the wire rope 73 from rubbing against the mounting sleeve 1 and causing damage, improve the service life of the wire rope 73, and improve the smoothness of the wire rope 73 when moving.

[0039] like Figure 2 and Figure 6 As shown, a sealing ring 10 is fixedly connected to the top of the mounting sleeve 1, and the inner wall of the sealing ring 10 is in contact with the surface of the positioning tube 8. A sealing ring 21 is fixedly connected to one side of the fixing sleeve 31, and the inner wall of the sealing ring 21 is in contact with the surface of the moving rod 345.

[0040] Specifically, sealing ring 10 can seal the gap between positioning tube 8 and mounting sleeve 1 to prevent rainwater from entering the interior of mounting sleeve 1 and causing corrosion to wire rope 73; at the same time, sealing ring 11 can seal the gap between fixed sleeve 31 and moving rod 345 to prevent dust and rainwater from entering the interior of fixed sleeve 31, thereby improving the service life of the components and ensuring stable and reliable monitoring, cleaning and protection functions.

[0041] The working principle of this invention is as follows: When in use, the infrared sensor 394 continuously monitors the track environment. When a train is detected passing by, the signal is transmitted to the external control device in real time, triggering the motor 32 to rotate forward. The motor 32 drives the screw 33 to rotate, and the screw sleeve 341 moves upward in a straight line along the screw 33 under the guidance of the limit rod 6. The slide rod 342 pushes the moving sleeve 343 to move laterally through the inclined port 344. On the one hand, the movable sleeve 343 drives the toothed plate 346 to move laterally via the movable rod 345. The toothed plate 346 drives the spiral scraper 382 to rotate and scrape along the surface of the PVC cylinder 37 via the toothed ring 381, removing dust and debris attached to the surface. On the other hand, the movable sleeve 343 simultaneously squeezes the corrugated sleeve 42, causing the air inside to be injected into the PVC cylinder 37 through the metal pipe 41, blowing out the fine dust in the gaps inside the PVC cylinder 37 in the opposite direction, ensuring the monitoring accuracy of the temperature and humidity sensor 36. Simultaneously, the rising of the screw sleeve 341 causes the sound sensor 3101 to extend synchronously. The sound sensor 3101 works in conjunction with the four vibration sensors inside the concrete sleeper 2 to capture abnormal sounds and vibration characteristics of the sleeper. Combined with the environmental data collected by the temperature and humidity sensor 36, the sleeper status information is comprehensively obtained. During this process, the moving sleeve 343 pulls the disc 72 down through the wire rope 73, compresses the spring 74 and causes the transparent plate 71 to descend, and the infrared sensor 394 continuously monitors the train status. When the train moves away and the infrared sensor 394 does not detect the train signal, the external control device drives the motor 32 to reverse, the screw 33 drives the screw sleeve 341 to reset downwards, and the slide rod 342 drives the moving sleeve 343 to move in the opposite direction. The sound sensor 3101 descends with the screw sleeve 341 and is stored inside the fixed sleeve 31 to avoid collision and dust contamination. At the same time, the spring 74 resets and pushes the disc 72 and the transparent plate 71 to move upwards. The rubber scraper 75 cleans the dust on the surface of the transparent plate 71 during the lifting and lowering process to ensure the accuracy of subsequent monitoring. The temperature, humidity, sound and vibration data collected by each sensor are transmitted to the data processing device 393 in real time. After analysis and integration, the data is sent remotely to the monitoring center to realize centralized management and real-time feedback of sleeper stability data.

Clearly, many modifications and variations can be made based on the content of this specification.
