Bar-clamping-preventing concrete vibrator and vibrating method
The invention provides a bar-clamping-preventing concrete vibrator and a vibrating method, and relates to the technical field of concrete vibrating equipment. The bar-clamping-preventing concrete vibrator comprises a vibrating bar, a transmission flexible shaft and a power assembly; the vibrating rod comprises a shell, a rotating shaft and a connecting piece; the shell is a flexible shell, the rotating shaft comprises a hollow part communicated with the inner space of the shell, the hollow part of the rotating shaft is communicated with the air pump through an air pipe, and when the vibrating rod is clamped, air in the inner space of the shell is pumped out through the air pump, so that the flexible shell is shrunk, and the diameter of the vibrating rod can be effectively reduced; the vibrating rod can be pulled out from the gap of the reinforcing steel bar; air is pumped in the shell through the rotating shaft, holes communicated with the outside do not need to be formed in the outer wall of the vibrating rod, and cement slurry cannot enter the vibrating rod even under the condition of violent vibration; the air pipe and the steel strand are combined to jointly form the transmission flexible shaft, the steel strand can evenly apply force on the outer side of the air pipe, and therefore the situation that air cannot be supplied due to the fact that the transmission flexible shaft locally extrudes the air pipe is avoided.
本申请提供了一种防卡棒混凝土振捣器及振捣方法，涉及混凝土振捣设备技术领域，包括振捣棒、传动软轴和动力组件；所述振捣棒包括外壳、转轴和连接件；所述外壳为柔性外壳，所述转轴包括与外壳内部空间连通的中空部，所述转轴的中空部通过气管与气泵连通，当发生卡棒时，通过气泵抽出外壳内部空间中的空气，使柔性外壳发生收缩，即可有效缩减振捣棒的直径，使振捣棒能够从钢筋间隙中抽出；且本申请通过转轴在外壳内部抽气，并不需要在振捣棒外壁上开设连通外界的孔，即使是在剧烈振动的条件下水泥浆也不会进入振捣棒内部；本申请将气管与钢绞线组合以共同形成传动软轴，钢绞线能在气管外侧均匀施力从而避免传动软轴局部挤压气管导致的无法供气。
