Description

Technical Field

[0001] This application relates to the field of belt conveyor technology, and in particular to a long-distance belt conveyor system with intelligent inspection. Background Technology

[0002] With the rapid development of infrastructure construction, my country has become the world's largest market for green sand and gravel aggregates. Large-scale construction aggregate mines are mostly located in the hinterland of mountainous or hilly areas, often requiring long-distance transportation to deliver finished or semi-finished aggregates to transshipment destinations. Therefore, the application of long-distance belt conveyors is becoming increasingly widespread. This brings with it the problem of conveyor inspection. Due to the long-distance transportation of belt conveyors, often several kilometers long, the efficiency and effectiveness of manual inspection are seriously insufficient.

[0003] Therefore, more and more projects are now using inspection robots to replace manual inspections. However, the transportation of sand and gravel aggregates generates a large amount of dust. If angle steel, rectangular steel, or similar materials are used as the planar track for the inspection robot, dust will accumulate on the track, affecting the stability of the robot's operation and the monitoring effect. In addition, since conventional conveyor structures do not reserve space for rail-mounted inspection robots, the installation and operating space of the robot is limited, resulting in the monitored object being too close to the robot, affecting the monitoring accuracy and effect. Summary of the Invention

[0004] This application provides a long-distance belt conveyor system for intelligent inspection, which solves the problem in related technologies where angle steel, rectangular steel, etc., are used as planar tracks for inspection robots, causing dust to accumulate on the tracks and affecting the stability of the inspection robot's operation and the monitoring effect.
