Compliance overview

Scope and applicability

This standard applies to the physical performance and intended use of mine auxiliary winders. It covers various types of equipment, including shaft sinking winders, dispatch winders, ore scraping winders, transport winders, and belt-braking mine hoists. This standard explicitly excludes auxiliary winders designed for the transportation of personnel. It is applicable to the safety hazards generated during all phases of the machine's lifecycle as defined in GB/T 15706.1.

Technical requirements

This standard is mandatory and outlines comprehensive safety measures to mitigate the 20 identified hazards during transportation, installation, operation, and maintenance. The requirements focus on ergonomic design, ensuring that sharp edges, protruding parts, and overheating surfaces are properly managed or guarded. Manufacturers must ensure that pressure piping and joints withstand 1.25 times the rated working pressure. For operational safety, the standard specifies strict criteria for braking systems. Most winders must be equipped with reliable working brakes, and specific types like belt-braking mine hoists and transport winders require independent safety brakes. The braking torque must meet specific minimum multipliers of the maximum or rated static torque depending on the winder category. Additionally, exposed rotating parts like transmission shafts and couplings must have protective devices complying with GB/T 15706.2. The standard also sets stringent environmental and operational thresholds, such as noise limits measured in dB(A), which vary by winder type and load condition. For underground applications with explosion-proof requirements, the electrical equipment must comply with GB 3836.1. Furthermore, belt-braking mine hoists must feature specialized safety devices, including overwind prevention, slack rope alarms, and emergency foot switches.

Testing methods

Compliance is verified through no-load and load tests conducted on a test bench or on-site. Under rated load conditions for at least 30 minutes, inspectors check operational stability, brake responsiveness, and contact area between brake shoes and wheels. Noise levels are measured according to the acoustic methods specified in GB/T 3768. Additionally, braking torque is measured using force sensors or dynamometers (accuracy class 2 or better), and manual operating forces are verified using tension meters.

FAQs

What specific types of equipment are covered under GB 20180-2006?

It covers various types of mine auxiliary winders, including shaft sinking winders, dispatch winders, car maneuvering winders, ore scraping winders, pillar pulling winders, transport winders, endless rope winders, air door winders, pneumatic winders, movable winders, and belt-braking mine hoists. It explicitly excludes auxiliary winders used for transporting personnel.

What are the specific braking torque requirements in GB 20180-2006?

The standard mandates specific minimum braking torque multipliers based on the winder type. For instance, transport winders require a braking torque of no less than 3 times the rated static torque, while pneumatic winders require at least 1.25 times. Manufacturers must verify these parameters during the load testing phase.

Does GB 20180-2006 include requirements for explosion-proof winders?

Yes, winders intended for underground use with explosion-proof requirements must possess explosion-proof capabilities. Their electrical equipment must comply with the stipulations of GB 3836.1.
