Description

Technical Field

[0001] The utility model belongs to the technical field of field bridges, and in particular relates to an anti-rush-out protection system for a power taking device. Background Art

[0002] After the container yard crane reaches the alignment area and uses the power-taking device, the driver should retract the power-taking device and wait until the retraction light comes on before continuing to move the truck out of the yard. However, in actual operations, the truck often does not slow down in advance when the driver reaches the alignment area. The inertia of the truck causes the power-taking device to rush out of the alignment area, so that the power-taking device cannot be retracted in time. If the truck continues to move at this time, it will cause the power-taking device to interfere with the busbar. Since the power-taking device is in the extended working state, the yard crane continues to move forward, which is likely to cause damage to the power-taking device and the busbar, and it is easy to damage related electrical equipment, bringing risks to port operations.
