Description

Special lifting appliance

Technical Field

The utility model belongs to the technical field of lifting appliances, and particularly relates to a special lifting appliance.

Background

Safety work is particularly important in the aluminium electrolysis industry today, and in particular, it is required to prohibit personnel from standing above the electrolysis cell during operation to prevent significant safety events.

The anode carbon blocks and steel claws used in the electrolysis shop are not fully poured, the pouring quality of phosphorus pig iron is poor, the steel claws are defective, current distribution is uneven due to factors such as anode long bags and the like, and the anode oxidation leads to depolarization. The steel claw guide rod group after the pole removal is lifted out of the electrolytic tank, and the anode clamp of the multifunctional crown block is required to be used for lifting.

The current chuck of multi-functional crown block positive pole anchor clamps in China is fixed design at present, so can't keep flat the steel claw guide arm group that takes off the utmost point to the positive pole tray, can only rely on steel claw guide arm group on new positive pole, again with the help of wire rope to bind this steel claw guide arm group from the middle part after handling to the tray, take off wire rope. In the whole operation process, the steel claw guide rod group depends on the new anode, so that serious potential safety hazards exist, and once the steel claw guide rod group is dumped, the new anode is possibly crushed, workers beside the new anode are possibly crushed, the ground is possibly crushed, and the anode guide rod which is subjected to pole removal is also possibly deformed seriously. Therefore, the current process of lifting the anode steel claw group has serious potential safety hazard, and the whole operation is time-consuming and labor-consuming, and influences the working efficiency, so a special lifting appliance is designed.
