In recent years, with the rapid development of China's economy, more than 20% of children's expanding equipment is put into use every year. At present, the total number of children's expanding equipment in use in China has reached more than 20,000. Large-scale expansion equipment for children is mainly distributed in sensitive areas such as political and economic centers, economically developed areas and tourist attractions. The participation of the public is extensive. The target group of passengers is also covered by young people, children, families and other groups.
At present, the expanding equipment for children in use in our country is different in old and new, coexistence of advantages and disadvantages, and uneven in safety and quality. There are not only inferior products produced by home factories at home and abroad, but also the latest products at home and abroad. Because of the market demand and the profit-seeking nature of production enterprises, children's expansion equipment is driven to a higher, faster and more stimulating development, which leads to the continual innovation of children's expansion equipment, diversification, complexity and large-scale forms; the combination of sports forms; high degree of mechanical and electrical integration of technology integration.
This trend not only brings pleasure to tourists, but also leaves potential safety hazards due to the lack of durability and reliability of some products or technologies. In addition, more than a quarter of the children's expansion equipment has been used for 20 years. These old equipment are inherently poor in quality. After years of continuous operation, fatigue of steel structure and main mechanical parts, aging of electrical system and foundation, if used and maintained improperly, some of the old equipment do not have the possibility of overall failure.
All of these show that quality control of production, self-inspection of operation and external supervision and inspection are all important means to ensure the safe and reliable operation of expanded equipment for children, and they are indispensable. However, unfortunately, due to the complex security situation of children's expanding equipment in use in China, the main responsibility of children's expanding equipment producers and users can not be effectively implemented, the honesty mechanism of enterprises in the industry has not yet been fully established, and the inertia role of planned economy thinking, as a technical institution affiliated to the government, supervision and inspection is often regarded as a guarantee for children's expanding. The only way to prepare for safe operation.
Nevertheless, as a safety technology supervision mechanism, the inspection agencies and inspectors of children's extended equipment have an inescapable responsibility in ensuring the safety of children's extended equipment, which can be said to be the last line of defense for children's extended equipment safety to some extent.
Therefore, how to do a good job in the supervision and inspection of children's extended equipment, ensure the quality of inspection, maximize the detection of problems, and prevent the occurrence of casualties in recreational facilities has become an unavoidable problem for children's extended equipment inspection institutions and inspectors.
