In order to ensure the safety and reliability of the use of the hydraulic prop, it is necessary to ensure that the technical and safety requirements of the maintenance process, according to the structural composition and characteristics of the hydraulic bracket, in accordance with the maintenance steps and attention in the maintenance process can be well completed the maintenance of the acrow prop, to achieve the safety of production under the premise of saving money and increasing efficiency.
Wave pressure bracket maintenance in the demolition of the acrow prop high pressure pipeline, must be the total valve off, and the operation handle to the left and right to move a little, back to the liquid, and then use a 40x 40MM2 old belt pressed on the quick connector, can be allowed to pry U-shaped card, the operator is strictly prohibited to put his head close to the quick connector.
When repairing the hydraulic prop, it is strictly forbidden for persons not related to the operation to pass through, i.e. stay or work in the scope of this bracket or the left and right two brackets. Bracket I must operate the bracket between the four columns of the bracket, and no part of the body may extend beyond the bracket. East bracket maintenance when replacing bracket parts, maintenance staff must stand in a safe place above the repaired parts diagonally, and must use 14# lead wire or 12.5MM small rope buckle to tie, in order to prevent the parts from accidentally falling down and tipping over and injuring people.
The adjustable props maintenance staff should make a good maintenance record, write down the maintenance support number, maintenance parts. If you want to oil and overhaul the coal miner drum, leave space for overhaul in advance. After the upper part of the coal miner is cut diagonally into the knife, here the bracket does not move, the hydraulic prop telescopic beam will be extended to connect the solid roof, and will be pushed out of the tail of the machine and This section of the scraper conveyor is pulled back. If the roof in front of this section is more than 0.34M, use a plank beam to hold the roof in front of the hydraulic prop.
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.
