Explosion-Proof Inspection Robot Chassis

The explosion-proof inspection robot wheeled chassis is a mobile platform specifically designed for flammable and explosive environments such as petrochemical plants, coal mines, and natural gas stations. Featuring four-wheel steering and four-wheel drive, it enables agile maneuvering and zero-radius turns, making it suitable for indoor and outdoor inspections on flat surfaces and in narrow passages. Its core lies in meeting explosion-proof certifications like GB/T 3836. It features a fully sealed explosion-proof housing, anti-static tires, intrinsically safe circuits, explosion-proof motors, batteries, control boards, and sensors. This ensures motors, batteries, and all electrical components operate without generating sparks or high-temperature surfaces. The chassis integrates explosion-proof infrared thermal imaging cameras, LiDAR, gas sensors, and intrinsically safe wireless communication modules, enabling high-risk inspection tasks such as pipeline leak detection, temperature anomaly monitoring, and valve status verification.

Table Parameters

Explosion-proof rating (highest industry level): CT6 is one of the temperature class ratings in China's explosion-proof electrical equipment certification. CT6 certification signifies that Xspirebot explosion-proof robots maintain surface temperatures below 85°C when operating in explosive environments, enabling safe operation in highly flammable gas atmospheres such as hydrogen and acetylene.

This certification is based on the national standard GB/T 3836 series and represents the highest explosion-proof safety rating currently attainable for industrial robots. CNEX-certified CT6-rated equipment is suitable for the most demanding industrial environments, serving as the safety foundation for building intelligent production systems in high-risk industries.

Safety Autonomous Navigation and Scheduling Function: The explosion-proof mobile robot chassis platform integrates the NV-Magic autonomous navigation system compliant with SIL3-PLe safety standards. Equipped with multi-sensor fusion technology, it enables flexible operation and intelligent protection. Supports safety stop, speed-limited operation, safety zone configuration, and secure task protection to ensure safe and efficient human-robot collaboration in hazardous chemical environments.

Precision Control: The modular explosion-proof drive-control module eliminates traditional high-noise, bulky planetary motors. It employs a core integrated drive-control motor delivering outstanding linearity, zero backlash, and durability. This design eliminates mechanical clearance, minimizes control latency, and ensures dynamic trajectory tracking at high speeds. Equipped with the NV-magic autonomous navigation module, it achieves repeatable positioning accuracy of up to ±3cm indoors and outdoors.

Batch Standardization: Comprehensive automotive-grade standardized production operations spanning design, procurement, manufacturing, and sales. Through a rigorous standardized system, every stage is executed with maximum efficiency and quality. Especially on the production line, all technical production personnel operate according to precise standardized procedures. The manufacturing process for each chassis remains consistent, eliminating quality fluctuations caused by human variation.

Typical Scenarios by Hazardous Substance Type

1. Petrochemical Sector

Refineries: Atmospheric and vacuum distillation units, catalytic cracking units, storage tank farms (presence of flammable vapors such as gasoline, diesel, LPG; explosion-proof rating must meet IIC level, capable of protecting against hydrogen/acetylene).

Chemical plants: Ammonia synthesis workshops (hydrogen environments), benzene/methanol production units (flammable vapors), polymerization reaction zones (dust + vapor mixture risks).

Key Details: Must withstand hydrogen sulfide corrosion, ground oil contamination, and temperature fluctuations from -20°C to 60°C. Tires require anti-static rubber (surface resistance <10⁹Ω) to prevent electrostatic charging.

2. Natural Gas and Energy Facilities

LNG Receiving/Regasification Terminals: Pipeline flange and valve inspections in cryogenic zones (-162°C) (methane environment, explosion-proof rating IIB).

Urban Gas Gate Stations/Pressure Regulation Stations: Methane leak detection in enclosed spaces. Requires IP68-rated chassis (prevents condensation ingress) + positive pressure ventilation system (prevents gas ingress into electrical compartments).

Gas Transmission Pipeline Valve Stations: Remote field sites requiring adaptation to dust, rain, and snow. Operational endurance ≥8 hours.

3. Pharmaceuticals and Fine Chemicals

API Synthesis Workshops: Acetone, ethanol, and other solvent volatilization zones (Class IIB), requiring resistance to organic solvent vapor corrosion (316L stainless steel housing).

Drying/Grinding Processes: Combustible dust environments (e.g., starch, pharmaceutical powders) (Dust Explosion Protection DIP A21), chassis gaps <0.5mm to prevent dust accumulation.
