In order to apply to the rail laying form of adding wrong carriageway, the wheels of the rear unloading inclined shaft skip car and counterweight I can be changed from flat wheels to grooved wheels to control the wrong direction, and the other side is flat wheels to facilitate crossing turnout and unloading curved rails.
The traction device of skip tramcar and counterweight is fixed and connected, and Babbitt alloy is used for pouring. And the pulling rope is about 100mm away from the center line of the skip, so that two wire ropes do not collide. When the skip or counterweight passes through the turnout, use the idler and vertical roller to reduce the traction angle. Generally, it will not produce too much lateral force within 7 °, which will not affect the operation of the skip and counterweight. The traction wire rope 10 m from the front of the skip shall fall below the rail surface into the groove of the rope supporting pulley.
In order to prevent the traction wire rope of the lower skip from rubbing with the steel rail and being rolled by the wheel of the rising counterweight, the rope groove, vertical roller and carrier roller shall be set at the turnout of the middle section passing the lane, and the carrier rope wheel shall be set on the monorail line.
In order to improve the skip filling coefficient, a cover plate of appropriate length can be added at the upper mouth of the skip.
On October 30, Li Zhenbo, General Manager of Information Technology at Shandong China Coal Group and General Manager of Zhongyun Group, was invited to deliver a keynote presentation at an activity organized by the Teaching and Research Group of the Shandong Province Technical and Vocational Schools Admissions and Employment (Industry-Education Integration) Center. The event brought together 23 technical and vocational schools across the province and focused on innovative integration of artificial intelligence with technical and vocational education, sharing practical achievements from the front lines of industry and jointly exploring new approaches to cultivating versatile digital-skills professionals through school-enterprise collaboration.
Recently, the Zhongmei Zhiren AI system, independently developed by the Intelligent Research Institute of Shandong China Coal Group, has continued to evolve and improve. Drawing on core technologies including large language models (LLMs), retrieval-augmented generation (RAG), AI agent workflow orchestration, multimodal vision, and audio and video generation, it is building a dedicated end-to-end AI platform for China’s industrial and mining supplies sector. The platform uses independently controllable AI technology to support the digital transformation of domestic and international trade and foster new quality productive forces.
Recently, three sets of software independently developed by Shandong China Coal Industry & Mining Supplies Group Co., Ltd. have successfully passed the review of the National Copyright Administration and obtained the Computer Software Copyright Registration Certificates. The three certified achievements are all built-in agent modules of the China Coal Zhiren AI System, namely: China Coal Zhiqing Image Management Tool V1.0, China Coal Construction Machinery Foreign Trade Independent Website System V1.0, and China Coal Mining Machinery Foreign Trade Independent Website System V1.0. This marks the continuous expansion of the ecological layout of the China Coal Zhiren AI System and the further consolidation of self-developed technical barriers.
Shandong China Coal Mining Support Equipment Co., Ltd. was founded in the 1990s with more than 1100 employees. It now has 53 professional companies, 3 Hong Kong companies, 1 British Cayman company and 1 American company. It is a large diversified industrial group integrating intelligent equipment manufacturing, e-commerce, software research and development and intelligent logistics, which is cultivated and supported by the Ministry of industry and information technology, the Ministry of Commerce, the development and Reform Commission, Shandong Province and Jining City.
