Not long ago, due to the impact of the epidemic, the south, North and West campuses of Zibo Vocational College implemented a closed policy to cut off the chain of virus transmission to the greatest extent. As the largest department in the University, the intelligent manufacturing college has 2233 students, but only 15 faculty members stay in the school for service. How to solve the students' three meals a day has become a big problem to be solved by the college teachers. It is understood that in order to deliver the meals in time and let the students eat hot meals, the left behind teachers shuttle between the canteen and dormitory and become the "meal delivery group" in the eyes of students. The delivery of each meal takes nearly two hours. After the delivery, the teachers can go back to the canteen for dinner. Pan Xuehai, Dean of intelligent manufacturing college, is also a member of the "meal delivery group". He eats and lives with everyone and is "online" all day. "If the epidemic is not over, my 'errand boy' will not stop working." Pan Xuehai said. The picture shows the delivery car version 1.0 made by the school teacher. In the early stage, all meals were delivered by manpower, with heavy workload and low efficiency. The party members and teachers of the college took action first. They began to study the distribution tools overnight. The version 1.0 of the dining car modified with the workshop material transfer car was on duty on time the next morning. Subsequently, the teachers focused on the idle electric tricycles on the campus. By adding shelves and hooks, two version 2.0 dining carts with larger carrying capacity and stronger mobility were put into use. Before the cold wave warning and rainy and snowy weather, the teachers completed the upgrading of the dining car by installing a rain proof roof. These two dining carts, which are frequently exposed in the circle of friends between teachers and students, can transport 300 meals at a time, and the meal delivery task of more than 2000 people can be completed in 30 minutes. The picture shows the delivery car version 2.0 made by the school teacher. Liu Xiaolin, deputy secretary of the general Party branch of the college, also released "advertisements" in the circle of friends and took the initiative to undertake the task of transforming meal delivery tools for brother colleges and departments. After modeling and design, motion simulation, blanking, welding, assembly, commissioning and other links, the "stretcher" and "hand push" transportation tools built by the Institute of intelligent manufacturing for its brother departments have been born one after another, playing an important role in all corners of the campus. The teachers and students of the Institute of intelligent manufacturing are contributing their own strength to the war epidemic. (outlook new era)
