Flexible connection device for portal transport truck

Abstract

The invention relates to a flexible connection device for a portal transport truck. Circular holes are formed in the middle parts of the tops of a left supporting leg and an inclined supporting leg; a third insulation sleeve is arranged on the circular holes of the left supporting leg and the inclined supporting leg; an insulation plate is arranged on the outer side of the third insulation sleeve; an adjustment pad is arranged above the insulation plate; a connection plate is arranged above the top of a right supporting leg; a circular hole is formed in the middle of the top of the right supporting leg; a first insulation sleeve is arranged in the circular hole of the right supporting leg; an insulation plate is arranged on the outer side of the first insulation sleeve; an adjustment pad is arranged above the insulation plate; a support is arranged between the connection plate and a girder; and the upper part of the support is hinged with the girder through a pin shaft. The flexible connection device has a simple structure, is safe and convenient to use, low in cost and good in connection performance and insulation performance, and can be used for solving the problem of the environment pollution to a large extent, improving the overhaul quality of an electrolytic cell, shortening the overhaul time and reducing the labor intensity of workers.

Description

technical field [0001] The invention relates to a flexible connection device, in particular to a flexible connection device of a gantry transfer vehicle arranged at the inspection passage of an electrolytic aluminum plant. Background technique [0002] The repair method of the traditional small 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 electrolyzer is powered off and cooled. It takes about 50 days to complete the maintenance process of an electrolyzer. Due to the small number of electrolytic cells, small cell type, flexible disassembly and assembly of electrolytic cells and furnace construction, this method of on-site maintenance can basically meet the requirements with less material consumption and less annual workload. However, with the continuous improvement and expansion of the production scale of electrolytic alu...

AI Technical Summary

Problems solved by technology

However, with the continuous improvement and expansion of the production scale of electrolytic aluminum plants and the type of electrolytic cells, the workload of repairing electrolytic cells is also increasing. This on-site maintenance method not only takes a long time to repair, affects the output of electrolytic aluminum, but also causes environmental pollution. The working conditions of the workers are poor, there are many safety hazards, and the repair quality of the electrolyzer cannot be guaranteed. The gantry transfer vehicle is one of the important equipment in the centralized overhaul. It carries the cathode transfer vehicle and large electrolyzer with a load of up to 300 tons. Therefore, the gantry The transfer vehicle is the key equipment for centralized overhaul, and the connection method and insulation method of the main beam and outrigger of the gantry transfer vehicle are the key to the success of the equipment
