冶金矿山中需要下放的井下设备较多。一般情况下,质量重、体积大的大型设备需要在井筒装备安装前,从立井井筒中下放到大件运输巷道,再通过大件运输巷道运送到安装位置。1传统下放方法存在的问题传统的下放方法:①采用单台凿井绞车下放设备,这种方法对凿井绞车的提升能力要求较高;② Metallurgical mine in the need to delegate more downhole equipment. In general, mass heavy and bulky large equipment needs to be lowered from the shaft of a vertical shaft to a large transport lane before it is installed in the shaft and transported to the installation site through an oversized transport lane. A traditional method of decentralization of the existing problems The traditional decentralization methods: ① single sinking winch decentralization equipment, this method of drilling shaft winch lifting capacity requirements are higher; ②
