OKOSCAN 73HS High-Speed Rail Testing System

OKOSCAN 73HS 系統是一種經濟的無損自動鋼軌檢測方案，可以可靠地定位所有類型的瑕疵，包括橫向和縱向水準裂紋、螺栓孔產生的裂紋等。本系統的運行速度高達40公里/小時 (24.85英里/小時)。

本系統包含：

• 1個探傷小車
• 4個輪式探頭
• 最少24個OKO-24超聲波模組
• 1個編碼器
• 1台裝有專用軟體的PC

探傷小車
探傷小車搭配車輪型探頭，可沿軌道軸線定位和移動。並會自動調整到適當軌距。
探傷小車優點：

• 可用於檢測半徑小於200米的彎道，若以較低的速度更可用於半徑不小於120米的彎道
• 可迅速自動調整軌距類型
• 維護簡便
• 具控制懸吊系統（傾斜）的能力。

• 3個2 MHz 70度感測器
• 1個2 MHz 50度感測器
• 1個2 MHz 37度感測器
• 1個4 MHz 0度感測器

1. 直接安裝在探傷小車上。提供更好的抗干擾保護、大幅縮短車輪型探頭連接電纜、通過乙太網電纜傳輸數據。
2. 安裝在車裡。探傷小車上沒有額外的負載可減輕重量，超聲波模組運作不受天氣影響。

The OKOSCAN 73HS System is a cost-effective NDT solution for automated rail track inspection, which allows reliably locating all types of fatal defects, including transverse and longitudinal horizontal cracks, cracks originating from bolt holes, etc. The System operates at a speed of up to 40 km/h (25 miles).

The System consists of:

• a flaw detection trolley
• 4 wheel probes
• OKO-24 ultrasonic modules (24 pcs minimum)
• an encoder
• a PC with special-purpose application software.

Trolley (Carriage)
The inspection trolley carries the wheel probes ensuring their positioning and movement along the rail axis. The trolley automatically adjusts to the gauge type (track width).

Track inspection trolley advantages:

• testing curves with a radius of less than 200 m (at a lower testing speed – of no less than 120 m);
• prompt automatic gauge type adjustment; 
• easy maintenance;
• controlling the suspension system (cant).

Wheel probes

The OKOSCAN 73HS System incorporates four (4) wheel probes, each comprising:

• three 70-degree transducers, 2 MHz
• one 50-degree transducer, 2 MHz
• one 37-degree transducer, 2 MHz
• one 0-degree transducer, 4 MHz

Ultrasonic modules
 

The OKOSCAN 73HS System employs OKO-24 single-channel ultrasonic modules with a frequency range from 1 to 7 MHz and initial pulse sending frequency of up to 4 kHz.

The modules can be mounted:

1. Directly on the trolley. The positioning option offers better protection against interference, shorter length of wheel probe connection cables, data transmission through the Ethernet cable.
2. In the vehicle. With this positioning option, there is no additional load on the trolley, and its weight is decreased, while the ultrasonic modules remain safe from exposure to climatic conditions impact.
