王楼煤矿设计开采能力为200万t/a,采用1台4JDM-40型调车绞车与装车站配合发货。笔者将重点介绍原调车绞车钢丝绳托辊装置的结构特点、存在的问题,以及改造后的结构特点与实际应用效果。1原托辊装置的结构特点原托辊装置的结构如图1所示。其特点是:支架布置在轴的两侧;轴两端设有开口槽,防止轴转动;挡板安装在轴的两端卡槽内;透盖布置在辊筒的两侧内孔处,通过螺栓安装在辊筒上,防止轴承轴向移动;轴承压装在轴上,轴承外圈与辊筒内孔配合。原结构中,钢丝绳在辊筒的外圆凹槽内运动,当辊筒外
Wang Lou mine design and mining capacity of 2 million t / a, using a 4JDM-40 shunting truck and loading station with the delivery. The author will focus on the original shunting winch rope roller device structure, problems, as well as the structural characteristics of the transformation and practical application. Structure of the original roller device The structure of the original roller device shown in Figure 1. The utility model is characterized in that: the brackets are arranged on two sides of a shaft; the two ends of the shaft are provided with an open slot to prevent the shaft from rotating; the baffle is arranged in the clamping slots at two ends of the shaft; The bolt is installed on the roller to prevent the bearing from moving in the axial direction. The bearing is press-fitted on the shaft, and the outer ring of the bearing cooperates with the inner hole of the roller. In the original structure, the wire rope moves in the outer circular groove of the roller when the roller is outside
