Description

Technical Field

[0001] This invention belongs to the technical field of high-speed railway line maintenance equipment, and more specifically, relates to an electromagnetic automatic collection device for iron filings from high-speed railway rail grinding. Background Technology

[0002] High-speed rail lines are a crucial infrastructure for high-speed railway operations. The rails of these lines require regular grinding and repair to ensure the smooth, stable operation and safety of high-speed trains. After grinding, a large amount of iron filings and dust are generated and left on the rails. Some of this dust accumulates on the grinding equipment, forming lumps of iron filings that also fall onto the tracks. Due to the high speed of high-speed trains, these iron filings are often kicked up by the trains, causing damage. In some tunnels, dust is stirred up and spreads throughout the track space, adhering to power supply equipment and causing power outages. Therefore, it is essential to promptly clean the grinding filings after rail grinding to ensure the safety of high-speed trains and power supply equipment.

[0003] Currently, the removal of iron filings from ballastless track on high-speed railways is done by workers using brooms and blowers to sweep away granular iron filings and by collecting larger pieces of iron filings during patrols along the line. This method results in low efficiency, long maintenance windows, and requires a large investment of manpower, leading to high labor intensity and increasing the risk of accidents caused by worker fatigue. Especially since maintenance windows on high-speed railways are all at night, the safety risks for workers are significant; the secondary dust generated during work severely impacts worker health and the safety of power supply and electrical equipment along the line; furthermore, manual work is greatly affected by subjective factors, making it difficult to guarantee the quality of the work.

This device comprises an electromagnetic body 1, a hydraulic lifting system 2, a lifting guide device 3, and an electrical control system 4. The electromagnetic body 1 is a prior art device, consisting of an iron core, a magnetic yoke, a coil, an insulating layer, and a shell. The iron core, magnetic yoke, and coil are the basic components for generating electromagnetic fields. The electromagnetic body 1 acts as a magnetic source, descending to a set position during operation and applying a positive current to attract iron filings. After operation, it is retracted, and a reverse current is applied to demagnetize and unload the iron filings. The hydraulic lifting system 2 enables the electromagnetic body 1 to descend from the bottom of the vehicle body to the target position at a set distance on the track slab. The lifting guide device 3 ensures that the lifting of the electromagnetic body is stable and reliable.

After unlocking, the unlocking signal is automatically provided to the control system of the engineering vehicle 17, enabling operation and movement. After operation, the locking and unlocking device 13 is manually operated. After locking, the locking signal is automatically provided to the control system of the engineering vehicle 17, allowing the engineering vehicle to run at high speed.
