How to ensure the safety of large water park equipment
With the improvement of living standards, amusement parks have flourished and become a good place for people to relieve the pressure of work and study and vacation and leisure. Especially the thrilling large-scale water park equipment is favored by the majority of tourists. However, in recent years, amusement equipment accidents have occurred from time to time. As an equipment manufacturer of Guangzhou Blue Tide Water Park, he has put forward several ideas for ensuring the safe operation of amusement equipment.
With regard to ensuring the safe operation of large-scale water park equipment , the government has given great attention, implemented a safety supervision system, and issued a series of regulations. Since 2000, the state has included large-scale water park equipment in the special equipment catalog. The State Council Order No. 373 “Special Equipment Safety Supervision Regulations” (hereinafter referred to as the “Regulations”) on the design, manufacture, installation, transformation, maintenance, use, and use of amusement facilities Inspection and testing have made clear regulations, and the safety and management of amusement facilities have further embarked on a standardized and standardized track. Through the work of safety management departments at all levels, especially the special equipment safety supervision agency of the quality supervision department, the national regulations and standards have been better implemented and implemented, the safety awareness of relevant departments has been greatly enhanced, and the attention of the society has continued to increase. It plays an important role in improving the quality and safety of the entire industry.
The safety of large-scale water park equipment is closely related to the quality of manufacturing and installation. According to incomplete statistics, there are nearly 200 large-scale water park equipment manufacturing units nationwide. In addition to the domestic sales of foreign manufacturing units, market competition is very fierce. In recent years, with the continuous increase of raw materials, standard mechanical and electrical products and other supporting parts and labor costs, the profit margins of enterprises have become smaller and smaller. For personal gain, individual enterprises have adopted methods such as cutting corners and shoddy materials to obtain profits; some enterprises have safety management The number of personnel and quality control personnel cannot meet the needs of production, which brings inherent hidden dangers to equipment production. At present, there is no relevant supervision and inspection outline and detailed rules, and it is impossible to effectively supervise the manufacturing process, key parts of materials, processing, and assembly of large amusement facilities.
The quality control of the installation process is an important part of the safe operation of large-scale equipment. We have repeatedly found that some amusement equipment factories did not or did not follow the “construction quality plan” and construction technical documents for construction, and the process control was not strict, which led to the installation process. Too much randomness, installation accuracy and quality are difficult to guarantee. Large-scale amusement facilities cannot be shipped from the factory due to installation and transportation. Some important steel structural parts must be assembled and welded on site. If the on-site construction personnel do not follow the construction process, the welding and installation quality will be difficult to control and guarantee. It is bound to cause hidden dangers to amusement equipment.
From the above point of view, it is particularly important to control the manufacturing quality, especially the quality of the installation process. The author believes that the key should be to do the following three aspects:
first, strictly review the technical information of the amusement facilities, and check the completeness, correctness and compliance of the equipment-related information (licensing, design document identification and type test report, installation notification, Factory documents, installation quality records and certification documents, etc.) for confirmation. And check the consistency of the actual equipment and the data (the conformity of the equipment installed on site and the design drawings after identification and type test is consistent with the type, type and parameters of the equipment that is manufactured and installed).Second, we must do a good job of supervision during the installation process. In the inspection process, it is often found that during the manufacturing (installation) process, the manufacturing (installation) unit may add filler materials at will due to large processing errors and other reasons, causing the welding stress concentration or insufficient strength at the place, which buried hidden dangers. Most of the main connecting parts (booms, rails, safety bars, etc.) are welded on site, and the welding quality is difficult to guarantee due to the limited conditions on site. Important parts (sliding shafts, rotating horses crankshafts, racing car steering shafts, etc.) may be welded with different types of steel or improperly selected welding wires (bars) when installed on site. Defects such as cracks are extremely easy to appear. The welding seam is relatively concealed and difficult to disassemble and assemble. During the assembly process, welding is also difficult to achieve, and the welding quality cannot be guaranteed.
For the above possible defects, intervene early in the inspection process and check the implementation of the construction process of the construction unit in accordance with the regulations. The disassembly and inspection shall be dismantled and inspected, and the verification shall be verified to prevent the defect from being missed.
Once again, it is necessary to urge the relevant units to implement the main responsibilities, and to check the acceptance inspection and registration.
The inspection process is also the process of propagating laws and regulations. Through the inspection, the production unit establishes rules and regulations, and the company’s main responsibility for safety and quality is implemented. After doing data review, equipment disassembly and inspection, etc., it is necessary to do a good job of acceptance inspection and improve equipment technical files. After passing the acceptance inspection, the user is urged to do a good job in the registration of the equipment and issue an inspection mark.
In the implementation of the inspection process, these three links are inseparable. Only by doing a good job in the inspection of each link, can it be possible to avoid the corresponding construction quality defects and ultimately ensure the safety and quality of the equipment.
In order to further improve the safety supervision and management of large-scale amusement facilities, I put forward the following suggestions based on the work:
1. Raise the entry threshold of amusement facilities manufacturing and installation units, strictly review and check, and control the scale and number of enterprises through the implementation of the manufacturing license system , Maintain the normal production order and improve the quality level of the enterprise.2. For companies that have obtained licenses, they can effectively control the operation of their products and quality systems through supervision and random inspections of their production and installation processes.
3. Accelerate the formulation of manufacturing and installation, transformation, and major maintenance procedures, carry out supervision and inspection work as soon as possible, ensure that manufacturing (installation) units have rules and evidence to follow, supervise and urge enterprises to implement main responsibilities, strict self-discipline, and strengthen production (installation) ) Supervision of unit process control.
4. Pay attention to the construction of special inspection culture. Only when manufacturers, installation units, and users always “plant the safety awareness of special equipment in their minds” and make safety a habit, can special equipment safety issues be called “safe.”
