Tianchuang robot T9-R is performing an inspection mission in the coke oven basement

Recently, 12 T9-R explosion-proof rail-hanging robots developed and produced by Tianchuang have been put into operation in the basements of 6 coke ovens in Shandong Tiexiong Metallurgical Technology Co., Ltd., completely replacing operation and maintenance personnel to independently perform daily inspections.

Shandong Tiexiong Metallurgical Technology Co., Ltd. is a large-scale domestic coal chemical energy enterprise. It has multiple tamping coke ovens and has formed a series of coal chemical products and coal-based energy production base such as metallurgical coke, coal tar, crude benzene, ammonium sulfate, gas, and power generation.

The basement of the coke oven is a first-level hazard source. Since the heating system inside needs to replace the heating waste gas with fresh gas every half hour to continuously ensure low-energy heating, operation and maintenance workers must inspect the basement every half hour. Check whether the equipment has abnormal reversing conditions. The basement is relatively narrow and closed, posing safety hazards such as high temperature and gas residues, and operating safety risks are high.

Under the fast-paced production mode of coke ovens, new challenges have been raised in terms of timeliness of operation, maintenance and reliability of equipment inspection. The batch commissioning of Tianchuang T9-R explosion-proof rail-hanging robot has filled the gap in intelligent operation and maintenance in high-temperature and explosive areas in coke oven basements, transforming the originally busy inspection section into an unmanned working area.

Twelve T9-R explosion-proof rail-hanging robots conducted inspections in the basement areas of six coke ovens in the factory area of Shandong Tiexiong Metallurgical Technology Co., Ltd. according to a track path with a total length of 2960 meters. Through the dual-light PTZ equipped with high-definition visible light and infrared thermal imagers, they monitored continuously around the clock, and used machine vision technology to intelligently identify and analyze the conditions of equipment such as the reversing position of the gas cock, the linkage mechanism of the exhaust disc in the coke side corridor, and the lift lever of the air inlet box in the machine side corridor. Keep abreast of equipment operating status. At the same time, it senses the temperature of the environment in the area, the concentration of toxic and harmful carbon monoxide gas, and promptly alarms, thereby ensuring the stable operation of the coke oven heating system.

When an abnormal situation occurs, the backend system will provide real-time warnings to remind the staff in the operation and maintenance centralized control room, and accurately guide the fault location on site for targeted treatment, greatly shortening the emergency response time and effectively ensuring the reliable operation of production equipment. It also solves the hidden dangers and shortcomings of manual equipment status inspection after the gas and exhaust gas equipment in the coke oven basement is reversed, saving manpower and improving the job safety factor.

The successful application of the T9-R explosion-proof rail-hanging robot in the coke oven basement scene effectively reduces the workload of operators in high-temperature and explosive areas and enhances the effectiveness of equipment status management. Help coal chemical energy companies transform their production from labor-intensive to intelligent intensive.
