Abstract
The invention provides a cutter suction dredger over-water floating pipe hydraulic fast connector and relates to equipment based on over-water movable dredge pipe fast butt joint. The fast connector is suitable for fast butt joint of a cutter suction dredger and over-water dredge pipes (also known as over-water floating pipes) of a dredging hydraulic reclamation project, and saves time and labor. The over-water dredge pipe fast connector comprises a connector body, a connecting sleeve, a hydraulic transmission device and a steel belt collection and release locking device. The hydraulic transmission device is arranged on the outer surface of the connecting sleeve and connected with the steel belt collection and release locking device through a connecting device. When the hydraulic transmission device and the steel belt collection and release locking device are in a connection state, the connector body is locked in the connecting sleeve. According to the fast connector, in the construction process of paving the dredge pipes on water, a guiding function of a guiding device of a male connecting sleeve is utilized, and therefore unfavorable influence on butt joint due to the fact that stormy waves cause the dredge pipes to bump and rock is reduced, and fast butt joint of the over-water dredge pipes and fast butt joint of the over-water dredge pipes and the dredger can be achieved through tightening of a traction steel wire. Accordingly, the fast connector is widely suitable for paving of the dredge pipes on the water where water current flow states are turbulent and the stormy waves are strong.
