Abstract
The utility model discloses an end part anticollision device of bridge cranes, which comprises a crane end beam, wherein end part anticollision device parts are arranged on the crane end beam and connected with a PLC (Programmable Logic Controller) arranged in a crane control circuit. The end part anticollision device is characterized in that the end part anticollision device parts comprise anti-derailment spacing components and two-crane anticollision spacing components. When the cranes move to the end part of a rail, triggering rods of rotating switches can be shifted by L-shaped spacing rods, so that internal contacts of the rotating switches are disconnected to trigger the PLC; when relative positions of the two cranes are close to a set position, light rays emitted by photoelectric spacing probes are reflected to receiving ends of the photoelectric spacing probes when encountering tin foil paper reflection plates of the opposite cranes; and internal contacts of the photoelectric spacing probes are disconnected to trigger the PLC. The device achieves that the adjacent bridge cranes can operate in a close distance and run safely.
