Connecting apparatus for catenary and aluminum guide stem

Abstract

The invention discloses a connection device of a suspension chain and an aluminum guide rod. The device is characterized by consisting of a hooked hanger, a fixing hoop of the aluminum guide rod and a safety self-locking pin, wherein, the fixing hoop of the aluminum guide rod is arranged at the periphery of the hooked hanger and installed in the hoop installation pin hole of the hooked hanger by a hoop connection pin; the safety self-locking pin is connected with the fixing hoop of the aluminum guide rod by a self-locking fixing sleeve and matched with a locking column arranged on the hooked hanger. The connection device of the invention has the advantages of simple manufacturing, convenient operation, high loading and unloading efficiency, safe and reliable connection and extreme low fault rate of operation equipment and is maintenance-free and can correctly and intuitively judge and confirm the firmness degree of the connection between a fixture and the aluminum guide rod so as to effectively avoid and control the occurrence of the falling of the aluminum guide rod; meanwhile, the connection device also has greater value of popularization and application as well as invisible, potential and latent security benefits and social benefits.

Description

technical field [0001] The invention relates to a connection device between a high-altitude catenary and a suspended object, in particular to a connection device between a catenary and an aluminum guide rod in a carbon anode assembly production line in the aluminum industry. Background technique [0002] With the continuous expansion of China's aluminum industry, the production capacity of carbon anodes required for electrolysis has increased, and the number of carbon assembly production projects has continued to increase. Due to the locked production process layout of the carbon block assembly line, workers must operate under the catenary and on both sides, and cannot be separated and avoided. Operate in catenary hazardous areas. At the same time, the loading and unloading of the aluminum guide rod and the off-line operation of the cast finished product before and after the rework of the residual pole suspension are all automated designs. Chain area to operate. [0003] A...

AI Technical Summary

Problems solved by technology

[0005] ① Part of the residual pole before suspension, due to uneven electrolytic ablation, uneven bottom palm, and uneven height, was dropped, bumped, dragged, pulled, bumped and bumped during transportation, resulting in serious damage to the top of the aluminum guide rod. stable, causing difficulty in suspension, and occasional falls

What is more serious is that the top of the aluminum guide rod is partially damaged and the steel sleeve is damaged during recycling. When entering the process of pressing off, pouring and straightening the aluminum guide rod, the aluminum guide rod and the suspension trolley are loosened, and the suspension mechanism of the trolley is not sensitive. Many factors such as the frequent loading and unloading of the aluminum guide rod make it difficult to control the fall of the aluminum guide rod and prevent the occurrence of human injury accidents

[0006] ②When carrying out and completing the suspension process, because the suspension trolley is suspended on the catenary chain, the observation distance is high and far away, and the double tabs of the suspension are blocked by the pull plate moving up and down and it is difficult to see clearly. It is difficult for the operator to accurately judge the reliability of the suspension between the aluminum guide rod and the suspension trolley amidst the chaotic metal impact sound of the catenary running. It is difficult to make accurate judgments in a closed enclosure

[0007] ③The suspension mechanism of the trolley frequently breaks down, and the amount of repair and maintenance is large and the cost is high

Taking the production capacity of 300,000 tons of aluminum as an example, about 10 to 15 trolleys need to be stopped for maintenance due to suspension problems after inspection every week, which not only affects production, but also costs maintenance man-hours and wastes materials
