Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of lifting appliance, particularly a kind of horizontal brush lifting appliance of plunging joint that is applied to the manufacture of boats and ships plunging joint workshop.
Background technology
Without key hydraulic pressure, connect the present application of technology more and more extensive, in modern ships, plunging joint and stern tube shaft mostly adopt without key hydraulic pressure and connect and install, and are characterized in that plunging joint and stern tube shaft fit quality are good, and install, dismantle very.The quality of plunging joint and stern tube shaft installation quality depends on the brush quality of stern tube shaft conical section and plunging joint taper hole, and the brush that the stern tube shaft conical section of take carries out plunging joint taper hole as benchmark is the link of most critical wherein.
As plunging joint is fixed on platform, adopt method and the plunging joint taper hole of crane vertical lifting stern tube shaft to carry out brush, need special crane and make special stern tube shaft lifting appliance stern tube shaft is sling, so just waste space and taken special equipment, and the larger stern tube shaft of quality is hung in very dangerous for a long time in the air, if often stern tube shaft is put down to suspension hook, when coordinating with stern tube shaft, again plunging joint is sling needs plunging joint, will certainly waste a large amount of time.
Lighter weight because of the relative stern tube shaft of plunging joint, conventionally in workshop, be stern tube shaft to be fixed on platform or shelf, plunging joint is clamped with lifting appliance, with the crane plunging joint along continuous straight runs of slinging, move with stern tube shaft conical section and coordinate, carry out the horizontal brush of plunging joint and stern tube shaft.The advantage of this brush mode is that lifting plunging joint is much easier compared with hanging stern tube shaft, has greatly saved work-hours, and after plunging joint is separated with stern tube shaft, has carried out crane in plunging joint taper hole mating process and can throw off at any time, has greatly improved the degree of utilization of crane.
When the horizontal brush method of employing is carried out the brush of plunging joint and stern tube shaft, common plunging joint lifting appliance is that thin Flat steel bending is become to two semicircles, at semicircle two ends difference weld clamp piece, in the middle of a semicircle, weld hanger therein, with bolt, clamp is locked, then two semicircular is enclosed within on plunging joint and forms a clip, adopt crane rope to run through the lifting that hanger carries out plunging joint, this mode has obvious deficiency:
(1) when the lifting appliance that uses single deck tape-recorder hoop to make is sling plunging joint, plunging joint is easy to along with crane rope rotates, now just must allow crane crawl, the locus of the workmen of brush simultaneously manual engagement crane accurate adjustment plunging joint, make plunging joint and stern tube shaft good fit, this will increase the difficulty of brush greatly.
(2) lifting appliance that uses single deck tape-recorder hoop the to make plunging joint of slinging, be equivalent to find with suspension method the center of gravity of plunging joint, and in fact when lifting appliance is made hanger complete with clip welding, therefore in fact the center of gravity direction of plunging joint can not overlap completely with hoisting wirerope, namely be difficult to guarantee plunging joint horizontal direction line of centers and be fixed on the stern tube shaft center superposition on platform/shelf, this will directly have influence on brush quality.
(3) in starting stage of brush, stern tube shaft cone is not fine with contacting of plunging joint taper hole, friction force when separated again after both laminatings is very large, the component of this friction force is transferred to crane rope by single hanger of the clip by plunging joint lifting appliance, add the gravity of plunging joint itself, once the power of transmitting surpasses the load-bearing ability of single hanger, hanger will directly rupture, and cause safety misadventure.
