A positioning device and positioning method for an electrolyzer transfer vehicle

Abstract

The invention relates to the field of positioning of electrolytic bath transfer vehicles and particularly relates to a positioning device and a positioning method for the electrolytic bath transfer vehicle during centralized major overhaul. The positioning device is provided with guide frames and a connecting shaft, and the specific structure is as follows: two trolleys are mounted on a cart of the electrolytic bath transfer vehicle, the guide frames are arranged at the lower parts of the two trolleys, a winch is mounted at the upper part of each trolley, the winches are connected with a movable pulley block through steel wire ropes, a connecting shaft is arranged at the lower part of the movable pulley block, and a hanging hook is mounted at the lower part of the connecting shaft. The positioning device has the advantages of smooth operation, reliable safety, good insulation property, simple structure, low cost and small maintenance amount when transported to an overhaul workshop.

Description

technical field [0001] The invention relates to the field of positioning of an electrolytic cell transfer vehicle, in particular to a positioning device and a positioning method for an electrolytic cell transfer vehicle during centralized overhaul. Background technique [0002] The repair method of the electrolyzer is generally to carry out a series of maintenance work such as dismantling the tank, repairing the tank shell, building the furnace and installing the upper structure on the spot after the power failure and cooling of the electrolyzer. It takes about 50 days to complete the repair process of an electrolyzer. The in-situ maintenance method can basically meet the requirements due to the small number of electrolyzers, small cell type, flexible disassembly and assembly of electrolyzers and furnace construction, less material consumption, and less annual workload. [0003] However, with the continuous improvement and expansion of the production scale of the electrolyti...

Problems solved by technology

[0003] However, with the continuous improvement and expansion of the production scale of the electrolytic aluminum plant and the type of electrolytic cell, the workload of repairing the electrolytic cell is also increasing, especially the current 500kA electrolytic cell has been widely used. Long repair time affects the output of electrolytic aluminum and causes environmental pollution. The working conditions of workers are poor, there are many safety hazards, and the repair quality of electrolytic cells cannot be guaranteed. Centralized overhaul tends to replace on-site overhaul

[0004] Concentrated overhaul is to transfer the electrolyzer to be overhauled to the maintenance workshop and then carry out a series of repair work, and then transport it to the electrolysis workshop. The tank shell, which needs to have good insulation, and because the electrolyzer transfer vehicle has to lift the electrolyzer shell weighing as much as 200 tons for long-distance transportation, it is easy to cause shaking during operation, which will affect the operation. Stability and safety, the positioning device of the electrolyzer transfer vehicle is also the key to the success of centralized overhaul
