AI Technical Summary
The existing laser anti-collision limit switches of overhead cranes have a short sensing distance, which cannot meet the safety range requirements of the crane during maintenance or repair.
The system employs a combination of first and second laser anti-collision limit switches, telescopic rods, and reflectors. The telescopic rods are driven by cylinders to extend the sensing distance, and the track dust is cleaned by air blowing pipes when the trolley is moving.
This extends the safe operating range, ensuring the safe conduct of inspection and maintenance work, while also cleaning dust from the tracks to prevent it from affecting the crane's movement.

[0013] When the first laser anti-collision limit switch 4 moves to a position where the distance between it and the first reflector 6 is less than or equal to the sensing distance, it receives the laser reflected back from the first reflector 6 and sends the signal to the travel control system of the first trolley 2, controlling the first trolley 2 to stop; when the second laser anti-collision limit switch 7 moves to a position where the distance between it and the second reflector 9 is less than or equal to the sensing distance, it receives the laser reflected back from the second reflector 9 and sends the signal to the travel control system of the second trolley 3, controlling the second trolley 3 to stop.
[0014] The first telescopic rod 5 and the second telescopic rod 8 are both air cylinders, and the first trolley 2 and the second trolley 3 are both provided with an air tank 13 for supplying air to the air cylinders and an air compressor 10 for supplying air to the air tank 13.
