Safety device in hoisting mechanism of ship unloader hopper

Abstract

The invention discloses a safety device in a ship unloader hopper lifting mechanism. The safety device comprises a full load hopper protecting device arranged at the position of an inlet of a lifting drum. The full load hopper protecting device comprises a hinged base hinged to a lifting mechanism machine frame, a protecting fence is hinged to the hinged base, one end of the protecting fence is provided with a driving rod perpendicular to an end section of the fence, a trigger rod is hinged to the bottom end of the driving rod, a connecting rod is fixedly arranged on the corresponding hinged base, the trigger rod is provided with a long hole, and the bottom end of the connecting rod is provided with a connecting bolt. The connecting bolt penetrates into the long hole, the bottom end of the trigger rod is provided with a driving piece, the machine frame is provided with a limiting switch matched with the driving piece, and the machine frame is provided with a limiting part which prevents the protecting fence from performing displacement excessively downwards. The feeding side of the lifting drum is provided with at least one detection head matched with the protecting fence, the detection head contacts with a sensor on the lifting drum through a sensing part, and the limiting switch and the sensor are electrically connected with a controller of the hopper lifting mechanism.

Description

technical field [0001] The invention relates to a safety device in the hoisting mechanism of a ship unloader hopper. Background technique [0002] Coal, iron ore and other materials are mainly unloaded by chain bucket ship unloaders. However, the chain bucket will inevitably be deformed during long-term use. After the chain bucket is deformed, it will still rise into the lifting tube of the lifting mechanism and will be stuck with the inner wall of the lifting tube. If you die, you will forcefully break the chain of the lifting system. [0003] Although a safety switch is currently installed near the hoisting drum, when the chain bucket is scratched and deformed, the chain bucket touches the safety switch to stop the ship unloader from working, however, once the current safety switch fails, it cannot be found in time, resulting in The chain will bring the deformed chain bucket into the lifting drum, causing equipment damage.
