Engineering surveying pay-off device
The invention provides an engineering surveying pay-off device. The pay-off device comprises a pay-off mechanism, the pay-off mechanism comprises a wire wheel, the wire wheel is located in a wire frame, a wire rope is wound around the wire wheel, one end of the wire rope is fixed to the wire wheel, the other end of the wire rope penetrates through a gap formed in the wire frame, and a laser transmitter fixed to the wire frame is arranged over the gap and used for providing a pay-off reference for the wire rope; the wire wheel sleeves the outer side of the first rotating shaft and is fixedly connected with the first rotating shaft; the lower end of the first rotating shaft longitudinally penetrates through the wire frame and is connected with a take-up mechanism for driving the first rotating shaft to rotate; the wire frame is connected with an adjusting mechanism used for driving the wire frame to rotate to adjust the paying-off angle through a supporting frame. According to the engineering surveying pay-off device, the pay-off angle can be accurately adjusted, the pay-off benchmark can be provided for a rope through the laser emitter, the pay-off precision is improved, and automatic take-up and pay-off can be achieved.
本发明提供了工程测量放线装置，包括放线机构，所述放线机构包括线轮，线轮位于线框内部，线轮上缠绕有线绳，线绳一端固定在线轮上，线绳另一端穿过线框上开设的缝隙，该缝隙的正上方设有固定在线框上的激光发射器，激光发射器用于为线绳提供放线基准；所述线轮还套设在第一转轴外侧并与其固定连接，第一转轴下端纵向穿过线框并与带动其转动的收线机构连接；所述线框通过支撑架与用于带动其转动来调节放线角度的调节机构连接；本发明提供一种能准确的调节放线角度，能利用激光发射器为线绳提供放线基准提高放线精度，并且能自动收放线的工程测量放线装置。
