The invention provides a crown block trolley stroke detection device. The crown block trolley stroke detection device comprises a coding ruler, a code reader, a dust cover and a communicating pipe. The coded scale is fixed on the end face of the cart on the outer side of the transverse moving track along the length direction of the transverse moving track, and the length of the coded scale is greater than the maximum transverse moving stroke of the trolley; the code reader is fixed on the trolley body, and the code reading end of the code reader faces the coded ruler; a dustproof cover is further arranged outside the coding ruler, the bottom of the dustproof cover is connected with the upper end face of the cart in a sealed mode to form a sealed dustproof area, and a long-strip-shaped measuring window is formed in the side, facing the coding size channel, of the dustproof cover; a sealing mechanism for sealing the measuring window is also arranged in the dustproof cover; the sealing mechanism comprises two supporting rollers and a flexible sealing plate arranged outside the supporting rollers in a sleeving mode. According to the invention, accurate acquisition of transverse travel data of the trolley under severe working conditions is realized, and the service life of the detection device is prolonged.
本发明提供了一种天车小车行程检测装置,包括编码尺、读码器、防尘罩和连通管;所述编码尺沿横移轨道的长度方向固定在横移轨道外侧的大车端面上,编码尺的长度大于小车横移的最大行程;所述读码器固定在小车车体上,读码器的读码端朝向编码尺;所述编码尺的外部还设置有防尘罩,防尘罩底部与大车上端面之间密封连接、形成密封防尘区域,所述防尘罩面向编码尺码道的一侧开设有长条形的测量窗;所述防尘罩内还设置用于封闭测量窗的密封机构;所述密封机构包括两根支撑辊,以及套设在支撑辊外部的柔性密封板。本发明实现了恶劣工况下小车横向行程数据的精准采集,延长了检测装置的使用寿命。
