The invention discloses a distance measuring device for truss hoisting. The distance measuring device comprises a first supporting column, the bottom of one side of an inner cavity of the first supporting column is fixedly connected with a rotating shaft through a bearing, the left end of the rotating shaft extends out of the first supporting column and is fixedly connected with a hand wheel, theend, away from the hand wheel, of the rotating shaft is fixedly connected with a first bevel gear, the surface of the first bevel gear is engaged with a second bevel gear, an inner cavity of the second bevel gear is fixedly connected with a threaded rod, and partition plates are fixedly connected to the tops of the two sides of the inner cavity of the first supporting column. Through cooperative use of the first supporting column, the rotating shaft, the hand wheel, the first bevel gear, the second bevel gear, the threaded rod, the partition plates, a threaded sleeve, a moving rod, a first sliding block, a first sliding groove, a vertical rod, a transverse plate and a second supporting column, the device has the advantage of facilitating height adjustment, and solves the problems that an existing distance measuring device for truss hoisting cannot conveniently adjust the height of a measuring instrument; and the measurement accuracy is easily influenced.
本发明公开了一种桁架吊装用距离测量装置,包括第一支撑柱,所述第一支撑柱内腔一侧的底部通过轴承固定连接有转轴,所述转轴的左端延伸至第一支撑柱的外部并固定连接有手轮,所述转轴远离手轮的一端固定连接有第一锥齿轮,第一锥齿轮的表面啮合有第二锥齿轮,第二锥齿轮的内腔固定连接有螺纹杆,第一支撑柱内腔两侧的顶部均固定连接有隔板。本发明通过第一支撑柱、转轴、手轮、第一锥齿轮、第二锥齿轮、螺纹杆、隔板、螺纹套、移动杆、第一滑块、第一滑槽、竖杆、横板和第二支撑柱的配合使用,具备便于调节高度的优点,解决了现有的桁架吊装用距离测量装置不便于调节测量仪的高度,从而容易影响测量准确度的问题。
