Description
Technical field
The present invention relates to the marine shafting installing area, particularly relate to the propeller hydraulic nut fastening device of the usefulness that is connected and fixed between screw shaft of ship and the screw.
Background technology
The installation of marine shafting, it is the difficult problem that Large-Scale Equipments such as puzzlement boats and ships, heavy-duty machinery are made, because axle system connects the running part that belongs to Large-Scale Equipment, this kind equipment gets into smooth, and not only power is big, and vibration is also big, can the whether firm quality that reaches the centering situation that connect is directly connected to equipment and boats and ships high efficiency, stable operation, particularly on the connecting link of propeller for vessels that plays progradation and screw shaft of ship, hydraulic nut has been brought into play very important effect in the connecting of these substantial equipment and axle system.
Hydraulic nut fastening adopted the method for binding suspender belt in the past, at first hydraulic nut is locked with suspender belt, regulate hoisting point position, preferably suspension centre is selected in the RC top of hydraulic nut, rotation is installed after being convenient to hydraulic nut and stern tube shaft centering like this, but, hydraulic nut is threaded because adopting with stern tube shaft, and generally adopt triangle thread, if such screw thread unbalance stress or deviations big city when mounted produces that to haul (be between the screw thread because the excessive generation heat of friction, easy local melting with two screw threads, after temperature reduces, just fuse into one) phenomenon, and, bring sizable difficulty with regard to the installment work that tightens like this to the hydraulic pressure nut because the locking hydraulic nut of suspender belt rotate also unusual difficulty of rice.Simultaneously,, be easy to generate irregular rocking when tightening, make its change in location, break screw thread easily, so just brought a lot of unsafe factors to installment work because hydraulic nut can't be fixed.
Summary of the invention
The technical problem to be solved in the present invention provides a kind ofly when propeller for vessels connects with screw shaft of ship, can make the hydraulic nut lifting that connects usefulness convenient, rotation is installed when tightening steadily avoids thread damage, the propeller hydraulic nut fastening device of handling safety.
The technical scheme that adopts is:
Propeller hydraulic nut fastening device comprises hoisting mechanism, supporting mechanism, rotating mechanism, location-plate.Described hoisting mechanism is made up of hanger and sleeve pipe, is equiped with two jackscrews on the sleeve pipe, and described sleeve pipe is fixedlyed connected with hanger.Supporting mechanism is made up of gripper shoe and back shaft, and an end of back shaft is fixedlyed connected with the gripper shoe upper end.Rotating mechanism is made up of roller, roller back shaft, positioning sleeve, lining gland, outer gland and bearing, positioning sleeve is contained on the roller back shaft, roller is contained on the positioning sleeve by bearing, gland is fixed with the roller both end sides respectively with outer gland and with bolt in being respectively installed with on the roller back shaft of positioning sleeve both sides, roller back shaft one end that outer gland is housed is installed with nut, and nut screws the back and is pressed on the positioning sleeve by packing ring.Casing pipe sleeve on the described hoisting mechanism is contained on the back shaft of supporting mechanism, adjusts sleeve pipe behind the lifting position on the back shaft, and two jackscrews on the locking sleeve are fixed on sleeve pipe on the back shaft.An end of gland was fixedly connected on the gripper shoe lower end of supporting mechanism in the roller back shaft of described rotating mechanism was equipped with, hydraulic nut is contained on the roller of rotating mechanism, described location-plate one end is installed on the back shaft end of thread, and be fastened on the back shaft by nut, the other end is overlapped on the hydraulic nut lateral surface, block the hydraulic nut slip-off preventing, constitute propeller hydraulic nut fastening device.
The present invention has not only solved the hydraulic nut rotation that causes because of lifting difficulty has been installed, and avoided the damage of double thread, reduced installation difficulty, simple in structure, handling safety, not only reduce labour intensity, shortened construction period, and improved the installation quality height, prolonged the service life of equipment.
