一种精确控制大型设备炉盖开启的装置
摘要：
一种精确控制大型设备炉盖开启的装置，包括炉盖、炉体、连接承重臂和支撑轴，所述支撑轴包括支撑轴外壳、旋转支撑轴和轴承，支撑轴外壳和旋转支撑轴通过轴承连接，所述炉盖和炉体分别通过连接承重臂与支撑轴外壳连接，与炉体连接的轴外壳内的旋转支撑轴内设置有丝杠，所述丝杠通过连接的减速电机控制。本发明提供一种丝杠传动控制大型设备炉盖开启的装置，与传统的气压和液压传动控制炉盖开启的方法相比，精确度更高，更容易控制，丝杠传动精确度可控制在0.1mm以下。
摘要（英）：

A device for accurately controlling opening of a large equipment furnace cover comprises the furnace cover, a furnace body, connection bearing arms and a supporting shaft. The supporting shaft comprises a supporting shaft shell, a rotating supporting shaft and a bearing, the supporting shaft shell and the rotating supporting shaft are connected through the bearing, the furnace cover and the furnace body are connected with the supporting shaft shell through the connection bearing arms respectively, a lead screw is arranged in the rotating supporting shaft in the supporting shaft shell connected with the furnace body, and the lead screw is controlled through a gear motor connected with the lead screw. The device for accurately controlling opening of the large equipment furnace through transmission of the lead screw is higher in accuracy and easier to control compared with a traditional method for controlling opening of the furnace cover through pneumatic transmission and hydraulic transmission, and the accuracy of the transmission of the lead screw can be controlled at 0.1 mm or lower.
