Description

一种堆取料机的回转角度检测机构 技术领域
本实用新型涉及堆取料机的角度检测装置技术领域，尤其涉及一种堆取料机的回转角度检测机构。
背景技术
斗轮堆取料机一般包括斗轮机构、回转机构、带式输送机、尾车、俯仰与运行机构。其中回转机构由回转支承和驱动装置两部分组成，用以使臂架左右回转。回转机构的一般结构可以参见授权公告号为CN204061731U、名称为“斗轮堆取料机回转机构”的实用新型专利，该专利具体公开了回转机构包括回转体，回转体通过旋转轴承安装在机座上，在机座上固定有大齿圈，在回转体上装有立轴，立轴下端装有与大齿圈相啮合的小齿轮，立轴的上端接驱动机构，所述的立轴的下端与回转体之间设有轴承，轴承的外圈镶嵌于轴承座内，轴承座通过安装套与回转体固定连接；所述的驱动机构包括减速器，减速器的安装法兰通过支架与回转体固定连接，立轴的上端直接与减速器的输出轴相接。
由于回转机构的回转角度较大，无法通过人工准确判断回转位置，因此，在堆取料机的回执机构设置回转角度检测机构来解决上述问题。现有技术中的回转角度检测机构结构可参见授权公告号为CN204228149U、名称为“用于堆取料机的回转信号发生器”的实用新型专利，参见图1，该专利公开了堆取料机的回转机构中的主动齿轮1和堆取料机的转动平台2，转动平台2与回转机构连接，转动平台2的下侧固定设置有一个支架3，支架3中固定设置有一个旋转编码器4，旋转编码器4包括有信号输出端和一个输入轴，支架3中设置有一个齿轮变速机构，齿轮变速机构包括有一个输入齿轮7和一个输出轴5，输出轴5通过联轴器6与输入轴连接，输入齿轮7与主动齿轮1啮合。齿轮变速机构将转动平台的旋转运动传递到旋转编码器的输入轴，使旋转编码器产生旋转信号，供外部连接的指示装置提供指示。
现有堆取料机的回转检测机构焊接在回转钢结构下平面上，与整机回转机 构一起运行，检测机构中的旋转编码器对回转检测机构中的小齿轮进行计数，达到检测的目的，而在实际应用的过程中，需单独增设一套检测齿轮，增加调整工作量，增设的旋转机构中自润滑轴承，小齿轮会增加易损件的数量和种类，加大维护检修的工作量。
