Vibration-falling-preventing filling rubber tube suspension device

The utility model discloses an anti-vibration falling filling rubber tube suspension device which comprises a U-shaped threaded rod, a nut, a bearing, a first circular tube, a pre-tightening force spring, a second circular tube, a strip-shaped pressing block, a through hole, a semicircular clamping block, a semicircular clamping groove, a supporting rod, a concave surface circular block, a U-shaped seat and transparent glass. The utility model has reasonable design, fastening effect using bolts, pre-tightening force is applied to the filling rubber pipe through the pre-tightening force springand the semicircular clamping groove; meanwhile, the performance of storing elastic potential energy after the spring is pressed is utilized; the slurry outlet of the filling rubber pipe is always subjected to the acting force given by the suspension device under the condition of vibration caused by starting and stopping of the grouting pump, slurry flow change and the like; meanwhile, the threaded friction structures arr
