Ton-class chemicals helm blade

Abstract

The invention relates to a ton-class chemicals helm blade and belongs to the technical field of ship equipment. The ton-class chemicals helm blade comprises a base plate, a plurality of horizontal separating plates, a plurality of vertical separating plates, a lower cast steel body, a water sealing tank, an upper cast steel body, a top plate, a plurality of hoisting holes, a plurality of water sealing wrapping plates and a discharging mechanism, wherein the horizontal separating plates and the vertical separating plates are welded into a crisscross frame skeleton; the base plate is arranged under the frame skeleton; the lower cast steel body and the upper cast steel body are welded on the right side of the frame skeleton; the water sealing tank is arranged under the lower cast steel body and the upper cast steel body; a circle of water sealing wrapping plates are welded outside the frame skeleton; two hoisting holes are formed on the water sealing wrapping plates; stainless tubes pass through the hoisting holes; and the stainless tubes are integrally welded with the water sealing wrapping plates. A large-size helm blade with such a structure has the advantages that the structural strength is high, the welding process is reliable, the mounting is convenient, the outline offset is reasonable, the resistance is obviously reduced, the cost is low, the modern industrial requirement is fully met, and the helm blade can be used for greatly promoting the speed of a ship and prolonging the service life of the helm blade.

Description

technical field [0001] The invention relates to a rudder blade, in particular to a 10,000-ton chemical ship rudder blade, which belongs to the technical field of ship equipment. Background technique [0002] With the large-scale shipbuilding, the quality of shipbuilding is getting higher and higher. In the past, for some parts with large lines, such as rudder blades, due to the difficulty in forming clad plates, all steel castings were used, but the use of steel castings required formwork. The formwork of different ship types cannot be reused, so time-consuming and labor-intensive, high cost and waste of consumables, and the internal structure of steel castings is limited by the casting process, and the strength is not enough; at present, some shipyards have also begun to use steel plates for welding and forming, but the design structure is unreasonable. The process is simple, some are fully water-through, and some are fully sealed. After being installed on a 10,000-ton ship...
