Title: TAIL END HOSE DEVICE, CONCRETE PUMP VEHICLE AND PIPELINE DELIVERY DEVICE
Abstract:
A tail end hose device used for a concrete pump vehicle comprises a delivery pipe (1). The outer lateral wall of the delivery pipe (1) is sleeved with a mass disc (2), and a gap is arranged between the inner lateral wall of the mass disc (2) and the outer lateral wall of the delivery pipe (1). A support part protruding out of the outer lateral wall of the delivery pipe (1) is arranged on at least one side of the mass disc (2).The mass disc (2) is connected with the support part through an elastic part so as to reciprocate along the axial direction of the delivery pipe (1). The device can effectively reduce the vibration when the tail end hose device delivers materials, and has high dumping working reliability and low operation cost. In addition, a concrete pump vehicle comprising said tail end hose device is disclosed. Furthermore, a pipeline delivery device is disclosed.
