The invention discloses a vertical lifting device for reinforcing steel bars. The vertical lifting device comprises a lifting barrel, wherein an operation hole which is through from top to bottom is formed in the lifting barrel; two clamping devices are arranged in the operation hole; the two clamping devices are symmetrically distributed in the horizontal direction; the two clamping devices are distributed up and down in the vertical direction; and the two clamping devices have height difference in the vertical direction. The two opposite clamping devices can clamp reinforcing steel bars through gravity thereof, and the reinforcing steel bars are clamped more tightly if the reinforcing steel bars are heavier, so that a protective rope can be quickly wound onto the reinforcing steel bars while the reinforcing steel bars drop to prevent the reinforcing steel bars from continuously dropping, and therefore, safety performance of the device is improved; and a clamping wheel is further arranged to keep stability, in a lifting process, of the steel rope, and the whole device can be lifted to specified height through a motor, so that labor of a worker can be saved.

    本发明公开的一种钢筋垂直提升装置,包括提升筒,所述提升筒内开有上下贯通的作业孔,所述作业孔内设有两个卡紧装置,两个卡紧装置在水平方向上对称分布,两个卡紧装置在竖直方向上上下分布,且两个卡紧装置在竖直方向上存在高度差,本发明设有的两个相对的卡紧装置能够通过钢筋自身的重力将钢筋卡紧,且钢筋越沉卡的越紧,当钢筋发生坠落时,能够快速将保护绳缠绕在钢筋上阻止钢筋继续下坠,提升装置的安全性能,还设有夹持轮保持钢索提升过程中的稳定性,还能通过电机将整个装置提升到指定高度,能够节省工人体。
