Description
Technical Field
The utility model relates to the technical field of ship power accessories, in particular to a rudder stock for a ship.
Background
The steering is realized by a rudder device in the running process of the inland river ship on the river. The rudder device comprises a rudder stock, rudder blades and a steering engine, wherein the steering engine generates torsion force to control the rotation of the rudder blades through the rudder stock.
As shown in fig. 1, the rudder stock is currently constructed as a rod body 01 and connecting parts at both ends thereof, wherein the connecting parts 02 connected with the rudder blade are flange structures, and the rudder blade is fixed on the rudder stock through the cooperation of bolts and the connecting parts.
The rudder stock applied to the small-sized ship of the type of the inland river ship has large self weight, and when the steering engine drives the rudder stock to rotate with the rudder blade, the steering engine is influenced by the weight to generate load force, so that the steering engine wastes excessive driving force, and the rotation efficiency of the rudder blade is influenced.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model aims to provide the rudder stock for the ship, which has the advantages of reasonable and simple structure, reduced weight of the rudder stock and improved structural strength of the rudder stock.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the rudder stock for ships comprises a rod body, wherein both ends of the rod body are respectively provided with an upper mounting part and a lower mounting part, the lower mounting part comprises a bottom plate and a side plate, the side plate is vertically connected with the bottom plate, a plurality of connecting holes are respectively arranged on the bottom plate and the side plate,
the body of rod includes core and overcoat, and the core is arranged in the overcoat, the core is made for the aluminum alloy, and the core includes center pole and a plurality of strengthening rib that set up around center pole periphery wall, correspond the strengthening rib on the overcoat and have the opening that supplies the strengthening rib to stretch out its body.
The utility model is further provided with: and the cavities formed between the adjacent reinforcing ribs are filled with filling components.
The utility model is further provided with: and a reinforcing piece is arranged at the joint of the side plate and the bottom plate.
The utility model is further provided with: the reinforcing rib is welded and fixed with the opening of the outer sleeve, and two edge wrapping parts are bent at the part of the reinforcing rib extending out of the outer sleeve and are abutted against the outer wall of the outer sleeve.
Compared with the defects in the prior art, the utility model has the beneficial effects that:
by providing a solid rudder stock as a combination of two parts, the sheath and the core, the cavity formed between the core and the sheath reduces the weight of the rudder stock. The structural strength of the rudder stock is improved by the structure of the core body.
