The safety of stage mechanical equipment includes the quality and safety of the equipment itself, as well as the operational safety during use. Let's first discuss the issue of equipment quality and safety. The selection, design, and calculation of equipment should meet the relevant safety requirements of basic stage machinery and non-standard mechanical equipment specifications and standards. The safety factors of steel wire ropes and lifting transmission chains under different usage conditions, the calculation of equipment structural stiffness and strength under full load, the torque verification of motors, reducers, and brakes, the verification of motor overload and driving force at full speed and full load, the verification of pulley drum diameter, and the rationality of equipment structure and transmission system layout are all basic mechanical equipment safety requirements that are fully and reasonably considered, Only stage machinery and equipment can meet basic safety requirements. Stage mechanical equipment should also be equipped with corresponding safety auxiliary devices and detection components according to equipment positioning and requirements. The commonly used safety devices for equipment on the platform include rope arrangement mechanism, loose rope detection, anti impact top switch, anti slip car detection, load detection, speed detection, position detection, limit position switch, positioning switch, etc; Commonly used safety positioning pins, anti shear devices, anti extrusion devices, protective nets, safety doors, protective railings, status warnings, guidance systems, fixed supports, various sensors, encoders, limit positioning switches, etc. for equipment safety devices under the platform. Many safety auxiliary devices for both on and off stage equipment are universal. The control system of stage mechanical equipment should fully consider corresponding safety measures. The hardware system should consider aspects such as redundant backup of equipment systems, emergency stop control, electromagnetic compatibility protection, voltage and current overload protection, grounding protection, safety circuits and electrical appliances, standard interfaces, data security, and user management of operation permissions; The software system should have a certain level of intelligence and logical judgment ability, with functions such as intelligent interlocking, security synchronization, misoperation protection, password protection, real-time switching between master and slave control, etc., to ensure that the equipment status is known and controllable, and emergency situations can be handled with one click. The above are the basic issues that need to be considered to meet the quality and safety requirements of stage mechanical equipment, and the safety auxiliary devices can be selected according to actual needs. At present, some stage machinery and equipment, due to factors such as cost, have almost no basic safety configurations and only meet the basic functional requirements of the equipment, which poses significant risks during use. Due to the low frequency and intensity of use of stage machinery and equipment, similar safety hazards are not easily exposed, which has also caused some manufacturers and users to have certain illusions and lucky mentality. But this situation is actually very dangerous. As a strong special equipment, stage machinery must comply with relevant equipment safety regulations and standards, and establish a clear concept for equipment selection.
