Description
Technical field:
The present invention relates to the connection set that the cutter suction dredger sludge drainage pipe is used.
Background technique:
At present cutter suction dredger stern steel sludge drainage pipe directly adopts flange, bolt to be connected with self-floating type rubber sludge drainage pipe waterborne, and not only labor intensity is big during the installation or removal of this kind Placement, and operator can not installation or removal during high sea.For overcoming the drawback of traditional Placement between the cutter suction dredger sludge drainage pipe, need a kind of device of being connected or breaking away from fast safely and reliably between cutter suction dredger stern steel sludge drainage pipe and the self-floating type rubber sludge drainage pipe waterborne of being used for.
Summary of the invention:
The object of the invention provides a kind of safe and reliable, convenient and swift connection set that is used for the cutter suction dredger sludge drainage pipe.
Technological scheme of the present invention is made up of connecting body, anchor ear, fittings body, oil hydraulic cylinder; It is characterized in that connecting body one end has flange to be connected with the steel sludge drainage pipe of stern; The connecting body the other end has the hemisphere face shape inner chamber that holds fittings body; There are two semicircular arc anchor ears on mouth edge at this hemisphere face shape inner chamber, and the rubber seal oil sealing is equipped with in the inboard of semicircular arc anchor ear, and an end of two semicircular arc anchor ears is hinged respectively at connecting body hemisphere face shape housing on one side; Connect a locking hydraulic jack between the other end of two semicircular arc anchor ears, the power source of locking hydraulic jack is provided by external hydraulic power unit; Fittings body one end has flange to be connected with the rubber sludge drainage pipe, and the fittings body the other end is the ball cross section shape cylinder that cooperates with connecting body hemisphere face shape inner chamber; An end and connecting body hemisphere face shape housing correspondence at two semicircular arc anchor ear dress locking hydraulic jacks are established safe pin-and-hole; Insert safety pin in the safe pin-and-hole and prevent that anchor ear from unclamping; Safety pin is controlled by oil hydraulic cylinder, and the hydraulic cylinder power source is provided by external hydraulic power unit; When rapid pipe joint connects; Handling the locking hydraulic jack earlier loosens anchor ear; Then the ball cross section shape cylinder of fittings body is filled in the hemisphere face shape inner chamber of connecting body; Drive the ball cross section shape cylinder that anchor ear is clamped fittings body through handling the locking hydraulic jack again, the rubber seal oil sealing of anchor ear inboard is with the gap sealing that is about between connecting body and the fittings body; For the anchor ear of guaranteeing to clamp does not get loose, can insert the pin-and-hole in body anchor ear and the connecting body to safety pin through the oil hydraulic cylinder of control safety pin, prevent to cause anchor ear to unclamp because of the locking hydraulic jack leaks; The quick disengaging of rapid pipe joint be earlier through the safety pin oil hydraulic cylinder withdrawing from the pin-and-hole of safety pin from anchor ear and connecting body, utilize the locking hydraulic jack to unclamp the realization fittings body to anchor ear again and connecting body breaks away from fast.
Outstanding feature of the present invention be remote-controlled operation just can realize between cutter suction dredger stern steel sludge drainage pipe and the self-floating type rubber sludge drainage pipe waterborne fast, safety is connected or breaks away from, but not the manual work of passing through of traditional type tightens or unclamps flange bolt and realize connection or disengagement between sludge drainage pipe; Rapid pipe joint is designed to spherical joint and can in connecting body 1, swings, and maximum is waved 10 ° of angles, has the remarkable result that adapts to reliably working under stormy waves, the very big rugged environment of surging.
