The invention discloses a building engineering manual lifting device. The device comprises a box, two direction-changing fixed pulleys symmetrically fixed to the top of a wall and two pulley blocks, wherein two triangular suspenders are symmetrically mounted on the upper surface of the box, a fixed wheel is mounted on each triangular suspender, the two fixed wheels are connected with the two pulley blocks respectively in a hanging mode, and an adjustment rope is wound around each direction-changing fixed pulley and the corresponding pulley block at the same side. According to the device, the box can be easily lifted by manpower through the pulley blocks, the box can be lifted to be suspended at a fixed point through cooperation of an inner ratchet and a spring pawl in a control box, and safety is enhanced; a special-shaped rotary shaft is in linkage with the spring pawl through a connecting rope, and the control box can conveniently place the box down; and through a reset spring in cooperation with the special-shaped rotary shaft, danger caused by hand slip is avoided, and the safety of the device is further enhanced.

    本发明公开了一种建筑工程手动升降装置,包括箱体、对称固定在墙体顶部的两个变向定滑轮和两个滑轮组,所述箱体的上表面对称安装有两个三角吊杆,每个所述三角吊杆上均安装有固定轮,两个所述固定轮分别与两个滑轮组挂接,每个所述变向定滑轮与同侧的滑轮组上共同绕制有调节绳索。本发明通过滑轮组使得箱体能够被人力轻松升起,通过控制箱的内棘轮与弹簧棘爪的配合使得箱体升起能够定点悬停且增加安全性,通过连接绳使得异形转轴与弹簧棘爪联动,便于控制箱能够下放箱体,通过复位弹簧配合异形转轴避免手滑发生危险,进一步增加装置安全性。
