Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of lifting appliance, particularly a kind of vertical brush lifting appliance of prop shaft that is applied to the manufacture of propeller for vessels axle turning shop.
Background technology
As everyone knows, the screw propeller in modern ships and prop shaft mostly adopt without key hydraulic connecting and install, and the quality of installation quality depends on the fit quality of prop shaft conical section and screw propeller taper hole.The brush that the prop shaft screw propeller conical section of take carries out screw propeller taper hole as benchmark is the most important link that guarantees both fit qualities.
Conventionally in workshop, there are horizontal brush method and vertical two kinds of methods of brush method.Horizontal brush method adopts the motion of translation dolly lift-launch prop shaft along continuous straight runs to carry out brush with adopting the vertical fixing screw propeller of special purpose device.The method need to add special-purpose prop shaft translation dolly and lay trolley track in layout workyard, workshop, also needs to design the vertical anchor fitting of special screw propeller simultaneously, and general shipyard is difficult to the condition that reaches such.Vertical brush method vertically slings prop shaft with crane with special-purpose prop shaft lifting appliance, and the screw propeller fixing with level carries out brush, the method to the requirement of place, equipment all well below horizontal brush method, by most shipyards are adopted.
When adopting vertical brush method to carry out the brush of prop shaft and screw propeller, traditional prop shaft lifting method is that suspension ring are fixed in the end that can lift by crane at prop shaft, with the crane suspension ring of slinging, or utilize the nut of propeller shaft that prop shaft carries that the pressing plate with hanger and prop shaft are compressed, then from fixedly steel rope lifting of hanger.Traditional prop shaft lifting method has obvious deficiency:
(1) adopt the suspension ring prop shaft of directly slinging, in the starting stage of brush, prop shaft is not fine with contacting of screw propeller taper hole, very large with the crane friction force of prop shaft when both are separated of slinging again after both laminatings, prop shaft quality is also large, and this friction force adds that the gravity of prop shaft all passes to crane by the suspension ring by prop shaft upper end, once the power of transmitting surpasses the load-bearing ability of suspension ring, suspension ring will directly rupture, and cause serious accident.
(2) adopt with the pressing plate of the hanger prop shaft of slinging, because adjusting the center of prop shaft aloft, lifting is used the line of centers of steel rope, these three line of centerss of the line of centers of the line of centers of hanger, prop shaft are difficult to overlap, also just cannot guarantee prop shaft and screw propeller taper hole center point-blank, certainly will directly affect brush quality.
(3) be no matter to adopt the suspension ring prop shaft of directly slinging, or adopt with the pressing plate of the hanger prop shaft of slinging, because two kinds of modes are all to hang lifting, be difficult to guarantee that prop shaft does not rotate or swings with steel rope with lifting, must use crane that prop shaft is slowly moved to screw propeller taper hole top, after the complete stop motion of prop shaft, the cone of prop shaft could be carried to body and aim at screw propeller taper hole quick travel to contact, this has just increased the operation easier of commander and crane greatly, has seriously reduced work efficiency.
