摘　　要：在路线复杂的隧道施工中,针对长距离且伴随平面转弯下运工况的连续皮带机设计难点,通过分析隧道各转弯段分布情况,采用输送带张力曲线图校核其张力分布情况,确定合适的驱动布置位置及功率配置,以实现R400 m级水平转弯,电控系统采用四象限变频器与普通变频器相结合的控制方式;现有相关规范中制动系统参数的计算公式已不再适用于此种工况,因此,修改完善制动力的计算公式,以选取合适的制动器参数,并根据下带张力分布需求提出下带驱动滚筒处需配置逆止器的建议。为类似路线工况的连续皮带机的设计开发工作提供思路及参考。In the construction of tunnels with complex routes,for the design difficulties of continuous belt conveyor with a longdistance,horizontal-curve and downwardtransport condition,by analyzing the distribution of each curve of the tunnel,the tension curve diagram of the conveyor belt is used to check its tension distribution,the appropriate drive layout and power configuration are determined to achieve a R400 m horizontal curve,and a control mode of combining the four-quadrant converters and ordinary converters is adopted for the electronic control system.The calculation formula for brake system parameters in the existing relevant specifications is no longer applicable to this working condition.Therefore,the calculation formula for brake power is modified and improved to select appropriate brake parameters,and a proposal of configuring a backstop at the lower belt drive drum based on the lower belt tension distribution demand is made.It provides ideas and references for the design and development of continuous belt conveyors with similar route conditions.
