6. A method according to claim 1, wherein in step S5, a jack-up tool is provided on the upper end surface of the tiller, the tiller is initially separated from the tiller by the jack-up tool, and the tiller is then lifted up completely by a lifting device.
7. A shift fork tiller on board flicking method as claimed in claim 6, wherein a slinger is provided at the top of the rudder trunk, the centre of said slinger being aligned with the centre of said tiller, said slinger being for mounting said lifting device.

Description

Shifting fork type rudder stock ship brushing method Technical Field The invention relates to the technical field of ships, in particular to a shifting fork type rudder stock ship brushing method. Background In the large ship construction process, the rudder stock is matched as a key process for rudder system installation, the processing of the rudder stock conical surface and the shifting fork type rudder stock conical hole is completed to be matched, the common matching method comprises the horizontal matching of the shifting fork type rudder stock conical hole and the vertical matching of the shifting fork type rudder stock conical hole, the two matching schemes are carried out in a workshop, the rudder stock and the rudder stock are required to be transported to the workshop, in the ship construction or maintenance process, the matching of the rudder stock conical hole is required to be carried out again due to the contact surface of the rudder stock conical hole and the rudder stock conical surface, if the rudder stock and the rudder blade are already installed, the complex processes of rudder stock disassembly, rudder blade disassembly, rudder house opening process hole, rudder stock transportation and the like are involved, and the defects of long construction period, large workload and the like are overcome. Disclosure of Invention In order to solve the technical problems, the invention provides a shifting fork type rudder stock ship brushing method, which can realize the rudder stock ship brushing on a ship, simplify the process, reduce the occupied space and save the resources. According to the embodiment of the invention, the method for the flicking method on the shifting fork type rudder carrier comprises the following steps: s1, adjusting a rudder blade to a zero position, stabilizing the rudder blade, and then raising a rudder stock to a preset position; S2, uniformly coating coloring oil on the conical surface of the rudder stock, and then descending the rudder stock to enable the conical surface of the rudder stock to be in plug-in fit with the conical hole of the rudder stock; s3, checking the height from the upper surface of the tiller to the upper end face of the tiller, so that the height difference between the upper surface of the tiller and the upper end face of the tiller is smaller than 0.05mm; S4, uniformly applying pressure to the upper end face of the rudder stock; S5, lifting the tiller, checking the contact condition of a taper hole of the tiller and a conical surface of the tiller, and grinding a contact point in the taper hole of the tiller; s6, setting the ratio of the contact area of the rudder stock and the rudder stock conical surface to the surface area of the rudder stock conical surface as A, and repeating the steps S4 and S5 until the ratio is less than or equal to 60 percent A. In some embodiments of the present invention, in the step S1, a clamping plate is disposed between the rudder blade and the hull, and the rudder blade is connected to the hull through the clamping plate. In some embodiments of the invention, in the step S4, the coloring oil is red oil or blue oil. In some embodiments of the invention, in step S2, after raising the tiller, the tapered bore of the tiller and the tapered surface of the tiller are cleaned. In some embodiments of the present invention, the pressure applied uniformly to the upper end surface of the tiller in step S4 is 2MPa or more and 3MPa or less. In some embodiments of the present invention, in the step S5, a jacking tool is disposed on an upper end surface of the rudder stock, the rudder stock is initially separated from the rudder stock by using the jacking tool, and then the rudder stock is completely lifted by using a lifting device.
