Abstract
A steering oar lifting mechanism comprises a support and a lifting oil cylinder which are fixedly connected with a ship body at a ship tail. The lower end of an oil cylinder of the lifting oil cylinder is hinged with hinged seats on the ship body at the ship tail; the upper end of a telescopic rod of the lifting oil cylinder is hinged with a hinged supporting seat of a steering oar base; the support is rotatably connected with the steering oar base through a hinge; and the mounting position of the hinge is higher than that of the hinged supporting seat. The steering oar lifting mechanism has the advantages of convenient maintenance, cost reduction and period decrease.
Description
Technical field
The utility model belongs to ship domain, especially a kind of rudder oar lifting mechanism.
Background technology
Screw propeller is the structure of seeing that is in the water, work under bad environment, can't keep in repair in case be out of order, it is common occurrence that boats and ships of working in the shallow draft rivers more particularly, screw propeller run into that sandstone are broken, and screw propeller must be surfaced and carry out maintain and replace, thereby boats and ships must lie up, and the work capacity that lies up is big, the cost height, and the cycle is long.
Summary of the invention
For maintenance trouble, cost height, the long deficiency of cycle of the rudder oar that overcomes, the utility model provides a kind of easy to maintenance, cost-cutting, the rudder oar lifting mechanism in minimizing cycle.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of rudder oar lifting mechanism, comprise support, the hoist cylinder of captiveing joint with the stern hull, the oil cylinder lower end and the free bearing on the stern hull of described hoist cylinder are hinged, the hinged-support of the upper end of the expansion link of described hoist cylinder and rudder oar pedestal is hinged, described bracket by hinges is connected rotationally with described rudder oar pedestal, and the installation site of described hinge is than the installation site height of described hinged-support.
Further, also be provided with the mechanical interlocking bolt on the described support, described mechanical interlocking bolt cooperates with bolt hole on the pedestal; When the pedestal inclination angle put in place, the bolt hole on the pedestal just cooperated with the mechanical interlocking bolt, positioned by mechanical interlocking bolt and hinge, even if hoist cylinder lost efficacy, pedestal also can remain on the incident angle of setting, realized mechanical interlocking.
Technical conceive of the present utility model is: be the convenient for maintaining screw propeller, best bet is exactly in needs, and the rudder oar can rise and surface, so designed this cover lifting mechanism.When needing repairing rudder oar lower apron, ship needn't lie up, and only needs the startup lifting mechanism that rudder oar lower apron is all emerged and gets final product.
Pendulum-type mechanism is stuck up in employing, be connected with hinge between rudder oar and the hull, hoist cylinder one end hinge is on rudder oar support, and the piston rod hinge of the other end is on rudder oar base plate, when needs perk rudder oar, hydraulic efficiency pressure system provides high pressure oil to oil cylinder, promote piston-advance, piston jack-up rudder oar since the rudder oar be fixed on the hull reinforced rib on support between also have hinge to be connected, therefore piston rod just promotes the rudder oar around this hinge rotary oscillation, till mechanism surfaces under water with all.
The beneficial effects of the utility model mainly show: easy to maintenance, cost-cutting, minimizing cycle.
Description of drawings
Fig. 1 is the scheme drawing of rudder oar lifting mechanism.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of rudder oar lifting mechanism, comprise support 1, the hoist cylinder 2 of captiveing joint with the stern hull, the oil cylinder lower end and the free bearing on the stern hull 1 of described hoist cylinder 2 are hinged, the hinged-support of the upper end of the expansion link of described hoist cylinder 2 and rudder oar pedestal 3 is hinged, described support 1 is connected with described rudder oar pedestal 3 rotationally by hinge 4, and the installation site of described hinge 4 is than the installation site height of described hinged-support.
Also be provided with mechanical interlocking bolt 5 on the described support 1, described mechanical interlocking bolt 5 cooperates with bolt hole on the rudder oar pedestal 3; When rudder oar pedestal inclination angle put in place, the bolt hole on the pedestal just cooperated with the mechanical interlocking bolt, positioned by mechanical interlocking bolt and hinge, even if hoist cylinder lost efficacy, pedestal also can remain on the incident angle of setting, realized mechanical interlocking.
In the present embodiment, hydraulic efficiency pressure system is injected hoist cylinder 2 with high pressure oil, can promote rudder oar pedestal 3 and upwards rotate, and can set the angle of inclination of rudder oar pedestal 3 in advance.
After the screw propeller of rudder oar surfaces, whole rudder oar is in heeling condition, can prevent the swing of rudder oar this moment by hydraulic locking, to guarantee rudder oar and staff's safety, but for safety factor is provided, we have also set up mechanical locking device, promptly after hydraulic oil is laid down, still can keep the rudder oar motionless.What we used is the bolt locking method, be that the rudder oar is when putting to the alignment of hold-down bolt hole and locking screw keyhole, bolt is penetrated and tightens, so just can guarantee effectively that the rudder oar maintains static, thereby prevent that the motion suddenly of rudder oar brings infringement for personnel and equipment when maintenance.
Claims (2)
1. rudder oar lifting mechanism, it is characterized in that: described rudder oar lifting mechanism comprises support, the hoist cylinder of captiveing joint with the stern hull, the oil cylinder lower end and the free bearing on the stern hull of described hoist cylinder are hinged, the hinged-support of the upper end of the expansion link of described hoist cylinder and rudder oar pedestal is hinged, described bracket by hinges is connected rotationally with described rudder oar pedestal, and the installation site of described hinge is than the installation site height of described hinged-support.
2. rudder oar lifting mechanism as claimed in claim 1 is characterized in that: also be provided with the mechanical interlocking bolt on the described support.
