Description

Supporting anticreep groove monitoring devices of unmanned on duty driving

Technical Field

The utility model relates to a safety guarantee equipment field, in particular to supporting anticreep groove monitoring devices of unmanned on duty driving.

Background

The bridge crane features that the load hung on the hook or other load taking device can be lifted vertically or moved horizontally. The mining area often needs to use the driving to carry out the transportation of mineral bulk cargo, unmanned on duty work has been realized to a lot of local driving at present, in the actual work process, the bulk cargo is big because of the surface variation, unmanned on duty driving is when snatching the bulk cargo, if bulk cargo surface curvature is too big, can cause the hank rope to take off the groove on the dolly upper portion cylinder, or grab bucket pulley takes off the groove, if not handle in time, when promoting, can cause the accident of breaking of cable wire hank rope, cause equipment to scrap when serious easily, seriously influence shipment business. Under the manual mode, artifical experience and observation according to, the slow correction of shutting down that can be timely, nevertheless in full-automatic mode, unmanned monitoring when equipment breaks down causes the occurence of failure more easily, more needs the real-time safety monitoring who guarantees equipment, provides the safety guarantee for unmanned on duty system safety, efficient operation.

The reason why the slot is disengaged when the vehicle is driven unattended is as follows; the back surface is irregular shape for the dry bulk cargo is stacked, can be because of the physical characteristic of bulk cargo after digging and getting, cause and sink from the eminence to low, the center department of digging and getting can form the pit, if the position of picking is great at the height difference, when forming grab bucket one corner contact material surface, can cause a torsional force, cause the promotion before snatching, the certain angle of switching rope is twistd reverse, the height position is great, can cause the skew position of cable wire on the cylinder, cause the wrong rail of cable wire because of losing the level when promoting, the derailment phenomenon, the hank rope can appear in the promotion process, the anticlotting accident.

When the steel cable derails on the cylinder appears in the grab bucket, when closed lifting can appear in the promotion, then rope climbing phenomenon appears, when climbing rope appears, the rope roll-off cylinder card that one end probably appears is to the bearing on, perhaps two ropes cause the grab bucket atress uneven because of following length difference, form the grab bucket rotation, hank rope.
