Embodiment

[0020] Example: such as figure 1 and figure 2 As shown, an auxiliary device for removing the rotor of a ship's steering gear includes a fixed plate 1 and a hydraulic cylinder 2. The fixed plate 1 is circular, and the fixed plate 1 is provided with four vertical through holes. The four vertical through holes are arranged symmetrically with the center of the fixed plate 1, and studs 3 are perforated in the four vertical through holes, and the upper ends of the studs 3 extend above the fixed plate 1, The upper ends of the studs 3 are fastened with positioning nuts 4, and the lower ends of the studs 3 extend below the fixing plate 1, and the upper surface of the fixing plate 1 is provided with four first rib plates 5 , the four first rib plates 5 are radially distributed on the upper surface of the fixed plate 1 with the center of the fixed plate 1 as the center, and the four first rib plates 5 are perpendicular to each other to form four right angles. The bisectors of the four...

Abstract

The invention discloses an auxiliary device used for removal of a steering gear rotor of a ship, and belongs to the technical field of ship building. The device comprises a fixed plate and a hydrauliccylinder; the fixed plate is circular; four vertical through holes are formed in the fixed plate; the four vertical through holes are symmetrically arranged about the center of the fixed plate; a double-screw bolt is arranged in each of the four vertical through holes in a penetrating manner; the upper end of each double-screw bolt extends out to the upper side of the fixed plate; a positioning nut is fastened to the upper end of each double-screw bolt; the lower end of each double-screw bolt extends out to the lower side of the fixed plate; the upper surface of the fixed plate is provided with four first strengthening tendon plates; a lifting hole is formed in each first strengthening tendon plate; the hydraulic cylinder is vertically arranged on the lower surface of the fixed plate; andthe center line of the hydraulic cylinder penetrates through the center of the fixed plate. According to the auxiliary device disclosed by the invention, when the steering gear rotor is removed, hydraulic drive is adopted to replace a method that the steering gear rotor is knocked by using a heavy object traditionally, so that the direction of an applied force is stable, the magnitude of the applied force is controllable, and the phenomenon that the steering gear rotor and a rudderstock are stuck due to improper removal can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of ship building, in particular to an auxiliary device for removing the rotor of a ship steering gear. Background technique [0002] In the process of ship construction or repair, if there is a problem with the fitting between the steering gear rotor and the rudder stock, it is generally necessary to remove the rotor and re-fit the rudder stock. The usual method is to use a heavy object to hit the rudder stock. The steering gear rotor is separated from the rudder stock. This method of dismantling takes a long time and is likely to cause deformation of the steering gear platform structure and bring hidden dangers to construction safety. Uneven force during impact may also cause the steering gear rotor and rudder stock to be difficult to separate. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an auxiliary device for dismantl...
