The invention provides a bridge crane capable of accurately determining the longitudinal position of a bridge frame, which comprises a high frame, the bridge frame, a trolley, a mounting plate, a dust cover, a coding ruler, a code reader and a cleaning mechanism, a mounting plate is fixedly arranged above the high frame in the length direction of the high frame, a vertically-arranged coding ruler is fixedly mounted in the middle of the mounting plate, a dust cover is fixedly connected to the side wall of the bridge frame, and the mounting plate is covered with the dust cover; the middle part of the dustproof cover is fixedly connected with a fixed seat extending towards the direction of the coding ruler; the code reader is arranged at the front end of the fixed seat; the code channel end of the coded ruler is opposite to the code reading end of the code reader; the cleaning mechanism comprises a driving wheel, a driven wheel, a steering transmission, a cleaning shaft and a brush. The linear motion code reader is adopted to read the number of code channels, so that the accuracy of bridge positioning is improved; through the cleaning mechanism, the dustproof cover and the reset mechanism, the code ruler and the code reader are kept clean and fixed in position, and the positioning accuracy is improved.
本发明提供了一种可精准确定桥架纵向位置的桥式起重机,包括高架、桥架、小车,还包括安装板、防尘罩、编码尺、读码器和清扫机构;所述高架上方沿其长度方向固定设置安装板,安装板的中部固定安装一竖直设置的编码尺,所述桥架的侧壁固定连接一防尘罩,防尘罩罩覆在安装板外部;在所述防尘罩的中部固定连接一向编码尺方向伸出的固定座,读码器安装于固定座的前端;所述编码尺的码道端与读码器的读码端相对设置;所述清扫机构包括主动轮、从动轮、转向变速器、清扫轴和毛刷。本发明采用直线运动读码器来读取码道数,提高了桥架定位的精准度;本发明通过清扫机构、防尘罩和复位机构,保持编码尺和读码器的清洁和位置固定,提高定位精准度。
