矿用索道固定抱索器夹紧力与力矩确定

Determination on Clamping Force and Torque of Fixed Gripper Applied to Mine Cableway

为了得出矿用索道固定抱索器抗滑力和夹紧力定量关系,确保固定抱索器安全可靠运行,通过对固定抱索器进行受力分析,得出了固定抱索器抗滑力与夹紧力、夹紧力与固定抱索器尾部螺栓力矩的力学关系,推导出了抱索器夹紧力的计算公式并给出计算步骤,提供了不同运行坡度下抱索器下滑力、夹紧力、紧固扭力扳手的力矩参考值。

In order to obtain the relationship between the sliding resistance and the clamping force of the fixed gripper applied to the mine cableway, to ensure the safety and reliable operation of the fixed gripper, a stress analysis was conducted on the fixed gripper.The mechan- ics relationship between the sliding resistance and the clamping force of the fixed gripper,the clamping force and the torque of tail bolt in the gripper was obtained.The calculation formula for the clamping force of the gripper was derived, the calculation procedure was set up and the downward sliding force, gripping force and torque reference value of the fastened torque spanner under the different operation slope were provided.
