[0002] With the rapid development of railway construction, the demand for long steel rails is increasing. Long steel rail trainsets play a crucial role in the construction and maintenance of seamless railway lines. A long steel rail trainset is a special trainset composed of various special vehicles with different functions and structures for transporting welded long steel rails. The design and use of long steel rail trainsets have become increasingly important. The use of long steel rail trainsets has greatly improved the efficiency and safety of railway construction and maintenance. It can quickly and accurately complete the loading, unloading and transportation of long steel rails, providing strong support for railway construction.

[0003] Currently, long rail train sets experience significant vibrations when transporting long rails, causing locking bolts and ballast to loosen.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example: A rail locking monitoring structure for long-rail vehicles

[0032] This embodiment provides a rail locking monitoring structure for long rail vehicles, including a locking detection device, a signal repeater 13, and an alarm display 6. This structure is used to monitor the locking status of the rails in real time and issue alarm prompts in abnormal situations, facilitating timely handling by operators. Figures 1 to 4 As shown.

[0033] Lock detection device:

[0034] Housing 12: Protects the internal sensor body 3 and signal transmitter 5, extends the service life of the locking detection device. The housing is firmly engaged with the rail by the fixing clamp 4, ensuring the stability of the equipment installation.

[0035] Locking weight 1: Locking weight 1 is placed on the rail and is magnetically connected to one end of the connecting rod 2 to monitor the locking status of the rail.

[0036] Link 2: One end of link 2 is connected to the locking pressure iron 1 by magnetism, and the other end passes through the housing 12 and is connected to the sensor body 3. Link 2 is provided with a sliding groove 10. The two ends of the sliding groove 10 are designed with bevels to effectively trigger the pulley 8 and lever 7 and other structures.

[0037] Pulley 8 and groove 10: Pulley 8 is installed inside the groove 10 on the connecting rod 2. The relative sliding between the pulley and the connecting rod is used to reflect the movement state of the rail. The sliding of pulley 8 enables the displacement signal to be collected in real time.

[0038] Toggle lever 7: Installed at the bottom of sensor body 3. A spring is provided between the toggle lever 7 and sensor body 3. When the pulley 8 slides in the slide groove 10 and exceeds a predetermined value, the toggle lever 7 rebounds upward and compresses the spring, squeezing the switch of sensor body 3 and triggering sensor body 3 to send a signal. After the pulley 8 slides into the slide groove 10, the spring relaxes and triggers the toggle lever 7 downward, turning off the switch of sensor body 3 and returning to the initial state.

[0039] Slider 9: Installed inside housing 12, made of nylon, with connecting rod 2 passing through slider 9 and slidably connected to pulley 8 to reduce sliding friction and improve structural durability.

[0040] Scale line 11: Set on the connecting rod 2, so that the operator can observe and record the movement distance of the connecting rod 2, thereby judging the locking status of the rail.

[0041] Signal transmitter 5

[0042] The signal processing section of the signal transmitter 5 adopts a waterproof potting process to ensure that the protection level reaches IP65 or above, which greatly improves the waterproof performance and service life of the equipment.

[0043] Signal repeater 13:

[0044] Inside the housing 12, the rail status signal sent by the sensor body 3 is enhanced and transmitted. Due to the power consumption and size limitations of the locking detection device, the design of the signal repeater 13 ensures stable signal transmission and avoids data loss or false alarms caused by signal instability.

[0045] The signal repeater 13 is equipped with a separate power supply and energy storage system, which can continue to operate normally when the generator is not turned on, fuel is insufficient or the vehicle loses power due to an accident, ensuring that the signal can be transmitted in a timely manner when there is an abnormality in the movement of the rails.

[0046] Alarm display 6:

[0047] The system receives and processes the rail status signal transmitted by the signal repeater 13; the alarm display 6 displays the detected information on the screen, and if an abnormal rail locking status is detected, it will immediately issue an audible and visual alarm to remind the operator to take appropriate safety measures.

[0048] The locking detection device of this invention adopts a modular design, which facilitates maintenance and replacement. The movement of the rail is determined through the cooperation of a mechanical structure and a limit switch.

[0049] The device features a low-power design and a built-in high-capacity lithium-ion battery, which can ensure continuous operation for one year on a single charge, meeting the needs of long-term use.

[0050] Signal processing section encapsulation and waterproof design: The signal processing and transmission sections of the sensor body 3 are encapsulated in a separate container and potting process is used to ensure that the device has a waterproof performance of IP65 or higher, effectively improving the service life of the equipment in harsh environments.

[0051] Working principle:

[0052] Fixing and initial installation:

[0053] The housing 12 of the locking detection device is securely fastened to the rail by the fixing clamp 4, so that the equipment is installed stably.

[0054] Locking weight 1 is placed on the rail and connected to connecting rod 2 by magnetism.

[0055] Rail movement detection:

[0056] When the rail moves due to external force, one end of the connecting rod 2 is magnetically mounted on the locking pressure iron 1, and the locking detection device is firmly clamped on the rail by the fixing clamp 4. When the rail shakes, the locking pressure iron 1 and the rail are relatively displaced, causing the other end of the connecting rod 2 to be relatively displaced with the pulley 8.

[0057] The pulley 8 is relatively displaced with the connecting rod 2 in the slide groove 10. When the displacement exceeds the predetermined threshold, the inclined openings at both ends of the slide groove 10 will lift the pulley 8, thereby triggering the switch of the lever 7 to activate the switch of the sensor body 3 and sending a status signal of rail movement.

[0058] Signal transmission and alarm:

[0059] The sensor body 3 transmits the collected rail offset signal to the signal transmitter 5 through the circuit. The signal repeater 13 is responsible for amplifying the signal and ensuring its stable transmission to the alarm display 6.

[0060] After receiving an abnormal signal from the rail condition, the alarm display 6 processes the signal and displays the abnormal information on the screen. At the same time, it issues an audible and visual alarm to remind operators to check and handle the situation in a timely manner to ensure the safety of railway transportation.

[0061] Optimization results:

[0062] High-efficiency signal transmission: Since the equipment may experience power outages during operation, the independent power supply system of the signal repeater 13 ensures that the signal transmission remains stable even under extreme conditions.

[0063] High-precision detection and recording: By setting scale lines 11 on the connecting rod 2, operators can directly observe and record the movement distance of the connecting rod to better assess the locking status of the rail.

[0064] Extended equipment lifespan: The signal processing section of signal transmitter 5 adopts a waterproof potting process to ensure that the protection level reaches IP65 or above, which greatly improves the waterproof performance and service life of the equipment.
