Description
Technical Field
The invention belongs to the field of anchor devices of water surface vessels, and particularly relates to a sliding anchor and a use method thereof.
Background
The hawser tube serves as a passage for the hawser when the vessel is set up and anchored, and is used for storing the anchor when the vessel is sailing. The hawser tube of the head anchor is arranged on the stem at the two sides or the forefront part of the bow of the ship and is in an inclined state. All hawse pipes are classified into a steep type and a flat type according to their degree of inclination with respect to the vertical. The abrupt cutting type hawser pipe is suitable for civil ships with larger freeboard or low navigational speed. When the abrupt cutting type hawse pipe is placed in the anchor, the component force of the gravity of the anchor in the direction of the central line of the hawse pipe is larger, and the anchor can easily overcome the friction force to slide downwards, so that the anchor is smoothly dropped.
For a ship with a small freeboard and a high navigational speed, due to the waves lifted by the ship during navigation, pitching of the ship and the like, if the anchor of the bow is positioned at a lower position, the anchor can invade into water, so that the navigational resistance of the ship is increased. There are also ships, because of the huge bulbous bow, the anchor can not touch the bulbous bow in the process of retraction. For both cases, the outlet position of the hawse pipe at the outer plate has to be raised, so that the included angle between the axis of the hawse pipe and the vertical line is increased, and a flat inclined hawse pipe is formed.
The biggest characteristic of the flat inclined hawse pipe is that the included angle between the flat inclined hawse pipe and the vertical line is larger, so that the component force of the gravity of the anchor in the direction of the central line of the hawse pipe is smaller, and when the component force cannot overcome the friction force between the anchor and the hawse pipe, the anchor cannot slide down, so that the anchor cannot be released.

The piston rod 5 is arranged in the cylinder body 4 and extends or retracts under the action of hydraulic oil; the central hole of the upper/lower flange 3 is matched with the piston rod 5, and the top end of the piston rod 5 passes through the central hole of the upper/lower flange 3 and is connected with the rod head 6. The club head 6 comprises a transverse plate and vertical plates positioned at two sides of the transverse plate, and holes are formed in the two vertical plates; one end of the center post 7 passes through the hole on one side riser and the other end passes through the hole on the other side riser. The section of the sliding anchor post 8 is a circular ring, is sleeved on the central post 7 and can rotate around the central post 7, and the sliding anchor post 8 corresponds to a circular hole on the hawse pipe 10. In the preferred embodiment, the top end of the slide anchor post 8 is higher than the topmost riser.
In this embodiment, the casing body 1 is a protective shell with an inner diameter capable of accommodating the cylinder, and serves to provide a mounting fulcrum for the whole device, and collect and then intensively discharge seawater possibly entering. The connection housing 2 is mainly used for the connection of the whole device to the hawse pipe. The upper/lower flange 3 serves to connect the housing body 1 with the connection housing 2 so as to firmly fix the entire slide anchor 9 device to the hawse pipe 10, and serves to guide the piston rod 5 so that the entire structure is more stable. The cylinder body 4 is located inside the housing body, is fixedly connected with the housing body 1, is used for supporting the directional movement of the piston rod 5, controls the piston rod 5 to stretch and retract through the driving of external hydraulic oil, locks the piston rod 5 in a fixed position, and withdraws the piston rod 5 when required.
