[0002] In the railway transportation sector, speed reduction jacks are key equipment for controlling the speed of rolling stock, and their performance directly affects traffic safety and transportation efficiency. Traditionally, the inspection of speed reduction jacks has relied mainly on manual labor. Inspectors need to check each jack along each track one by one, which is not only labor-intensive and inefficient, but also makes it difficult to capture the dynamic work done by the speed reduction jacks during the rolling stock process and the temperature changes after the work is done in real time and accurately.

[0003] Due to the lack of effective online monitoring methods, faulty gearboxes often go undetected and unaddressed. Especially when a gearbox is operating with a malfunction, its temperature can rise abnormally, easily leading to safety hazards if not addressed promptly. Furthermore, manual inspections rely on experience-based judgment, making it difficult to generate standardized testing data. This hinders the scientific analysis and systematic maintenance of gearbox performance, failing to meet the high-efficiency and precise safety requirements of railway transportation.

[0020] This embodiment discloses a dynamic performance inspection and recording device for deceleration pylons capable of real-time video transmission. The lack of online monitoring methods makes it difficult to detect faulty deceleration pylons in a timely manner, and manual inspection relies on experience and produces non-standard data, failing to meet the high-efficiency and accurate requirements for railway equipment safety assurance. Referring to… Figures 1-5 It mainly includes an inspection component 1, upper and lower connecting rods 2 and a suspension component 3; wherein, the top of the inspection component 1 is connected to the bottom of the upper and lower connecting rods 2, and the top of the upper and lower connecting rods 2 is connected to the bottom of the suspension component 3.

[0021] The top of the inspection component 1 is connected to the bottom of the upper and lower connecting rods 2, and the top of the upper and lower connecting rods 2 is connected to the bottom of the suspension component 3. The three components are connected in sequence to form the overall structure of the equipment. The suspension component 3 serves as the connection carrier with the sled vehicle, and its specific structure enables a stable connection between the equipment and the vehicle. The upper and lower connecting rods 2 act as a connector between the suspension component 3 and the inspection component 1, allowing the inspection component 1 to flexibly adjust with the sled vehicle's posture. Through this connection method, the inspection component 1 moves synchronously with the vehicle, thereby accurately aligning with the deceleration top in the track to complete the dynamic recording of work and temperature detection.

[0022] Reference Figures 1-3 as well as Figure 5The inspection component 1 includes an inspection machine mounting base 101, a camera 109, a 4G module 1010, and a circuit board 1012. A start switch 102, a network port 103, a charging port 104, a power switch 105, and a USB 106 are respectively installed on one side wall of the inspection machine mounting base 101. A first acrylic waterproof cover 107 and a second acrylic waterproof cover 108 are sealed and bonded to the other side wall of the inspection machine mounting base 101. A battery 1011 is installed on the inner bottom wall of the inspection machine mounting base 101. The camera 109 is installed on one side inside the inspection machine mounting base 101, and the 4G module 1010 is fixed to the inner top wall of the inspection machine mounting base 101. The camera 109 has two output ports: one is a temperature measurement port, and the other is a video recording port. The temperature measurement port corresponds to the first acrylic waterproof cover 107, and the video recording port corresponds to the second acrylic waterproof cover 108. The circuit board 1012 is installed inside the inspection machine mounting base 101 and is electrically connected to the battery 1011, camera 109, 4G module 1010, power switch 102, network port 103, charging port 104, power switch 105 and USB 106.

[0023] Circuit board 1012 serves as the central control unit, integrating a power management module and data processing algorithm to dynamically allocate the power supply of battery 1011, prioritizing the real-time working needs of camera 109 and 4G module 1010.

[0024] The camera 109 adopts a dual-spectrum design. The visible light port (camera port) is aligned with the second acrylic waterproof cover 108 to record dynamic video of the deceleration top contacting the wheel. The infrared temperature measurement port (temperature measurement port) is aligned with the first acrylic waterproof cover 107 and integrates online temperature measurement function to detect the temperature change after the deceleration top performs work in real time.

[0025] The 4G module 1010 is connected to the circuit board 1012 via a high-speed bus, supporting TD-LTE / FDD-LTE dual-mode transmission to ensure low-latency uploading of video streams and temperature data; The start switch 102 adopts a dual-contact design. When the device scans the track electronic tag, it triggers the circuit board 1012 to start the synchronous acquisition of the camera port and the temperature measurement port, and activates the 4G module 1010 to establish a wireless transmission channel.

[0026] The power switch 105 is connected to the battery 1011 via a low-impedance wire to control the overall power supply; the charging port 104 supports the QC3.0 fast charging protocol.

[0027] The dual-port data from camera 109 is encoded and compressed by circuit board 1012 to form H.265 video stream and temperature data packet. One stream is stored on a local TF card (accessible via USB 106 / Ethernet port 103), and the other stream is encrypted and transmitted to a remote terminal via 4G module 1010.

[0028] The circuit board 1012 has a built-in low power detection circuit. When the battery 1011 voltage is below 20%, it automatically shuts down the 4G module 1010 and retains the basic functions of the camera 109. When it is below 10%, it starts the low power mode and only retains the temperature measurement port and local storage.

[0029] If the 4G module 1010 signal is interrupted, the circuit board 1012 will trigger the caching strategy, temporarily storing the real-time data to the TF card. Once the signal is restored, the cached data will be transmitted first to ensure that critical information is not lost.

[0030] Acrylic waterproof cover: The first acrylic waterproof cover 107 and the second acrylic waterproof cover 108 are bonded to the side wall of the inspection machine mounting base 101 with sealant to form IP67 protection, preventing rainwater or dust from entering and affecting the normal operation of the camera 109 and the temperature measurement port.

[0031] Reference Figure 1 , Figure 2 and and Figure 4 The suspension assembly 3 includes a hook base 301, a lifting rod 302, an eccentric pressure roller 303, and a rotating shaft 304; wherein, the side wall of the hook base 301 is provided with a sliding groove for sliding on the lifting rod 302, the side wall of the hook base 301 is rotatably connected to the eccentric pressure roller 303, and the two ends of the eccentric pressure roller 303 are fixed with the rotating shaft 304.

[0032] The hook base 301 has through holes at both ends for the rotation of the rotary shaft 304; a spring pin 305 is connected to one side of the top of the hook base 301, and a handle 306 for limiting the eccentric pressure roller 303 is connected to the bottom of the spring pin 305. The top of the upper and lower connecting rods 2 is connected to a ball joint hinge, and the top of the upper and lower connecting rods 2 is connected to the bottom of the hook base 301 through the ball joint hinge; the bottom of the upper and lower connecting rods 2 is connected to a flange, and the bottom of the upper and lower connecting rods 2 is bolted to the top of the inspection machine mounting base 101 through the flange.

[0033] The rotating handle 306 drives the eccentric pressure block 303 to rotate around the rotating shaft 304. The eccentric structure presses the lifting rod 302 into the groove of the hook base 301, forming a friction lock. Combined with the safety hook bypassing the physical constraint of the lifting rod 302, a dual guarantee of mechanical pressing and physical limiting is constructed.

[0034] When the elastic pin 305 is pulled out, the handle 306 can rotate freely to adjust the hook position; after the elastic pin 305 is inserted, the handle 306 is locked in the clamping position to prevent the eccentric pressure block 303 from loosening due to slippage vibration.

[0035] The ball joint at the top and the ball socket of the hook base 301 form a universal joint, allowing the equipment to rotate freely within a range of ±25°, compensating for the pitch and roll angles when the vehicle is rolled, and ensuring that the inspection component 1 is always aligned with the deceleration top.

[0036] The bottom flange is rigidly connected to the inspection machine mounting base 101 by bolts. It adopts a double anti-loosening method with spring washers and thread locking agent to prevent the connection from loosening due to vibration and ensure the stability of data acquisition.

[0037] The working principle of this utility model's deceleration top dynamic performance inspection and recording device capable of real-time video transmission is as follows: First, the device is fixed to the hook rod 302 of the sledding vehicle via the suspension assembly 3. In specific operation, first pull out the elastic pin 305 on one side of the top of the hook base 301, then turn the handle 306 to the other side, aligning the sliding groove on the side wall of the hook base 301 with the hook rod 302 and hanging it there; then rotate the handle 306, causing the eccentric pressure roller 303 to rotate around the rotary shaft 304 (the rotary shaft 304 rotates within the through holes at both ends of the hook base 301). Initial fixation is achieved through the contact between the eccentric pressure roller 303 and the hook rod 302. Then, lower the elastic pin 305 to limit the rotation of the handle 306, and simultaneously hang the safety hook around the hook rod 302 and onto the lower lifting ring, completing the stable suspension of the device.

[0038] Secondly, the upper and lower connecting rods 2 are connected to the bottom of the hook base 301 through the ball joint hinge at the top, which can adapt to the angle changes during the vehicle's gliding process. They are also connected to the top of the inspection machine mounting seat 101 of the inspection component 1 through the flange at the bottom, so as to realize the rigid connection between the suspension component 3 and the inspection component 1 and ensure that the inspection component 1 is stably aligned with the deceleration top in the track when the vehicle is gliding.

[0039] After the equipment is started, the power switch 105 on the inspection machine mounting base 101 is turned on, and the battery 1011 supplies power to components such as the circuit board 1012, camera 109, and 4G module. When the vehicle drives out of the hump with the chute, when the inspection component 1 scans the start electronic tag set in the track, the start switch 102 triggers the equipment to enter the working state: the camera 109 captures the dynamic video of the deceleration top contacting the wheel in real time through the camera port corresponding to the second acrylic waterproof cover 108; at the same time, the camera 109 detects the temperature change after the deceleration top has worked through the temperature measurement port (integrated online temperature measurement function) corresponding to the first acrylic waterproof cover 107.

[0040] The collected video and temperature data are processed by circuit board 1012 and stored locally on the device (they can be downloaded to a computer via USB 106 or Ethernet port 103 for subsequent analysis). Simultaneously, they are transmitted in real-time to the large display screen on the hump tower via a 4G module (wireless transmission module). The remote interface synchronously displays visible light video (the deceleration jack's operation process), infrared temperature images (heating status), temperature curves, sling speed, and other data. The system automatically determines whether the temperature exceeds the threshold using circuit board 1012. If an anomaly is detected, the information is recorded in an alarm table, alerting operators to handle the situation promptly, thus achieving efficient inspection and safety assurance of the deceleration jack's dynamic performance.
