Description

TECHNICAL FIELD

[0001] The present application belongs to the field of offshore ship design and construction, and particularly relates to a guide device for high-precision positioning of a pod in a limited space. BACKGROUND

[0002] The main body mechanism and functional modules of a ship type designed with a suspended pod propulsion device are mainly arranged along the vertical direction of the ship body, and when installed, the steering unit module and the driving unit module of the pod propeller are divided into upper and lower parts and are connected at the flange surface of the structural base. If the ship type product is arranged for construction on an inclined shipway, since there is a certain inclination angle when installed on the inclined shipway and the limited space around the pod is narrow, the pod module as a whole needs to be placed on a special tool carrier before the equipment is shipped out and transported to the shipyard, and the oil top is set below the carrier to complete the folding installation requirement by using a lifting scheme from bottom to top. In the process of lifting, the pod needs to continuously adjust the lifting stroke and precision to meet the appropriate inclination angle to avoid collision with the surrounding structure of the cylinder. Therefore, the present patent is designed from the perspective of high-precision positioning and installation of the pod lifting, and a guide device is installed on the cylinder structure, which can effectively eliminate safety hazards such as collision under the premise of ensuring installation precision, and assist the smooth installation of the pod in the limited space.

[0013] The application will be further described in combination with the drawings.

[0014] A guiding device for high-precision positioning of a hanging cabin in a limited space, comprising a first fixed seat and an auxiliary structural member, the auxiliary structural member being provided with a horizontally arranged lower seat plate and a vertically arranged side plate, the side plate being fixed at one end of the lower seat plate, the upper seat plate being fixed on the side plate, the edge of the ship body structure being inserted into the opening formed by the upper seat plate and the lower seat plate, the bolt being sequentially fixed through the upper seat plate and the lower seat plate, the second fixed seat being fixed on the lower surface of the end of the seat plate away from the side plate, the first fixed seat being welded on the lower surface of the ship body structure, the adjusting bolt being sequentially fixed through the first fixed seat and the second fixed seat and being fixed in cooperation with the adjusting nut; the rubber roller is arranged on the side plate and located above the upper seat plate.

[0015] Four sets of positioning and guiding devices are evenly arranged along the center of the opening under the main hull structure plate before the lifting of the pod. First, a first fixed seat is welded at a suitable position on the hull bottom plate. Then, the lower seat plate of the positioning and guiding device is positioned with a safe distance according to the distance between the pod and the rubber roller. The gap between the pod and the rubber roller is adjusted by adjusting bolts. After positioning, the adjusting bolts are used to install the upper seat plate and the side plate of the guiding device. The inclination angle is adjusted according to the slope of the berth, and the upper and lower seat plates are fastened by bolts. Rubber pads are arranged between the upper and lower seat plates and the hull structure for protection. The lifting oil is started to lift the pod. After the upper opening of the pod enters the main hull, the posture is not adjusted, and the lifting continues. When the pod is inclined and contacts the guiding roller, the roller assists the pod to continue lifting through rolling friction. When the lifting stroke is about to end, that is, when the pod bottom plate is at a proper distance from the hull bottom plate, the bolts at one end of the fixed seat and the lower seat plate of the guiding device are removed, and the guiding device is moved out of the limited space. The remaining operation is completed by precise positioning and leveling through the oil top to complete the whole lifting process of the pod.

[0016] By setting the positioning and guiding device in the limited space, excessive posture adjustment in the construction process is avoided, the construction efficiency is improved while the construction precision is ensured, and the problems of poor quality and safety are solved.
