Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard applies to the safety requirements for electrically or hydraulically driven friction mine hoists, winding mine hoists, disc-brake mine winders, and block-brake mine winders. It is mandatory for both explosion-proof and non-explosion-proof types used in mining operations. However, it does not apply to belt-brake mine winders. Compliance with GB/T 15706.1 is also referenced for general machinery safety.
Технические требования
The standard outlines comprehensive safety measures addressing various hazards identified during the equipment's lifecycle, including mechanical, electrical, and hydraulic failures. It specifies strict requirements for operational safety, component integrity, and control systems. Manufacturers must ensure that all technical content complies with the mandatory provisions outlined in this document. Key technical requirements cover the dimensional ratios between drums, friction wheels, and steel wire ropes, ensuring adequate safety factors for different mining applications (coal vs. metal/non-metal mines). The standard also dictates specific limits for braking performance, including braking torque ratios and safety braking deceleration values under various operational states. GB 16542 is referenced for cage safety. Furthermore, the standard mandates specific protection devices for the electrical control systems, such as overwind, overspeed, and depth indicator failure protections. These safety devices must be configured in an independent dual-line format to ensure redundancy. Requirements for hydraulic systems, including cleanliness levels and pressure testing, are also specified in accordance with GB/T 3766.
Методы испытаний
Testing methods include noise measurement at the operator position according to GB/T 13325, ultrasonic flaw detection for main shafts and welds (GB/T 11345 and JB/T 1581), and braking torque measurement using force gauges. Hydraulic system performance and cleanliness are tested per GB/T 3766 and GB/T 17489. Explosion-proof performance must be verified according to the GB 3836 series.
