All-in-one machine for ship rudder propeller shaft installation

Abstract

The invention discloses an integrated machine for installing rudder and propeller shafts of ships, which includes a running mechanism for driving the integrated machine to move. The running mechanism is provided with a main platform. The four corners are equipped with a horizontal movement mechanism, and a column is arranged above the horizontal movement mechanism, and a lifting cylinder for lifting the main platform is arranged inside the column, and an adjustment platform for placing rudder blades is arranged above the bottom frame, and the bottom frame is located on both sides of the adjustment platform. There is a rudder blade mounting frame, and a detachable propeller mounting frame is provided at the front end of the traveling mechanism. The present invention uses the existing berth track of the berth to design a longitudinally advancing and retreating installation platform trolley, which solves the problem that the propeller may collide with the rudder arm when the propeller is installed and enters the car, which hinders the propeller from being installed in place. Utilizing the invention to install rudder blades can realize free adjustment in six dimensions, reduce the hoisting and dismantling procedures of rudder and paddle mounting frames, improve efficiency and reduce costs.

Description

technical field [0001] The invention relates to ship manufacturing and installation equipment, more specifically to a ship rudder propeller shaft installation integrated machine. Background technique [0002] The installation of rudder blades, propellers and shafting is an important engineering task before a ship is launched, especially the installation of rudders and propellers, usually by welding lugs on the hull plate, using wire ropes and multiple chain hoists Adjust the propeller and rudder in place respectively for installation. Since the weight of the propeller and rudder reaches tens of tons or even hundreds of tons, this method has great potential safety hazards and low construction efficiency. Some shipyards have begun to use the rudder propeller installation platform for rudder propeller installation. At present, the rudder propeller installation platform trolley is mainly a product developed by Japan and Shanghai Jiaotong University. The form and function of th...

AI Technical Summary

Problems solved by technology

[0003] 1) It cannot be applied to ships built on berths. Since the berths have the rails required for launching, they can only advance and retreat longitudinally for the installation of oars and rudders, and are not suitable for the above products

[0004] 2) If the technical solution of the above product is improved and changed to install the propeller and rudder in the longitudinal direction, there are still some problems: when the propeller is installed in the longitudinal direction, the propeller collides with the rudder arm; frame collides with propeller

[0005] 3) The horizontal and vertical rails need to be laid separately, and the propeller mounting frame and the rudder mounting frame must be hoisted separately, and the installation efficiency is low

[0006] 4) Although the XYZ three-dimensional direction can be adjusted, the attitude such as the angle of the rudder and propeller cannot be adjusted

[0007] 5) When the main platform rises, it is inconvenient for people to board the platform

[0008] 6) High cost
