Example one

Referring to fig. 1 to 4, the ship hoisting structure provided by the present application is applied to a case where two gantry cranes perform loading and hoisting operations together. The two gantry cranes are respectively a first gantry crane 101 and a second gantry crane 102, the first gantry crane 101 and the second gantry crane 102 are arranged in parallel along the length direction of the dock (direction a shown in the figure), and the length directions of main beams of the first gantry crane 101 and the second gantry crane 102 are both the width direction of the dock (direction B shown in the figure).

The ship hoisting structure comprises a bow hoisting row 103 and a stern hoisting row 104; the fore-aft direction of the ship is the length direction of the dock, the fore hanger row 103 is used for connecting the first portal crane 101, and the aft hanger row 104 is used for connecting the second portal crane 102. In the fore-aft direction (direction a shown in the figure) of the vessel (the structure shown in the figure is the superstructure 105 of a bulk carrier), the distance between the bow row 103 and the stern row 104 is greater than or equal to a first defined distance, which is the sum of half the width of the main beam of the first portal crane 101 and half the width of the main beam of the second portal crane 102.

Particularly, in order to ensure that the lifting rope extends along the gravity direction when the ship is hoisted, the hoisting row needs to correspond to the position of the trolley on the portal crane as much as possible. The width of the main beam of the gantry crane is generally wide, and when the two gantry cranes are arranged, the width of the main beam needs to be considered, that is, the distance between the center line of the main beam of the first gantry crane 101 and the center line of the main beam of the second gantry crane 102 is at least the sum of half of the width of the main beam of the first gantry crane 101 and half of the width of the main beam of the second gantry crane 102 (i.e., the first defined distance). Then, in order to satisfy the above requirements, the distance between the bow hanger row 103 connected to the first portal crane 101 and the stern hanger row 104 connected to the second portal crane 102 also needs to be greater than or equal to the first defined distance. It should be noted that the drawings are illustrated with two thin main beams for showing the specific structure of the superstructure 105.

The hoisting rows of the common ship are respectively arranged on the left and right enclosing walls, and the two gantry cranes are respectively used for hoisting at two sides of the ship in the width direction, so that the width of the ship is larger than a first limited distance. For a ship with a narrow width, the arrangement mode cannot meet the requirement. If the length of the ship from the head to the tail meets the requirement, the hanging row can be arranged in the fore-aft direction of the ship, namely two gantry cranes respectively lift at two sides of the ship in the fore-aft direction, and the two gantry cranes are respectively connected with the fore hanging row 103 and the stern hanging row 104. Specifically, the two gantry cranes can lift the ship in a lifting manner.

The application provides a boats and ships hoisting structure makes the operation of hoist satisfy the operating mode requirement through the position of rearranging the row of hanging, applicable in hoist the boats and ships that the width is narrower, for example hoist the less double fuel ship type of superstructure 105 width to there is significant meaning to superstructure 105 overall construction's implementation.

Specifically, referring to fig. 1, the two gantry cranes have the same specification, that is, the width of the main beam of the first gantry crane 101 and the width of the main beam of the second gantry crane 102 are both 16m, and correspondingly, the first defined distance is 16 m. The distance between the bow hanging row 103 and the stern hanging row 104 is more than or equal to 16m along the fore-aft direction of the ship.

In an alternative of this embodiment, the bow hanger row 103 is mounted to the platform plate 106 of the vessel and the stern hanger row 104 is mounted to the stern bulkhead 107 of the vessel.

In this embodiment, since the location of the sling design is the stress point during hoisting, the location of the sling in the superstructure 105 also needs to be considered for strength. Generally, the plate materials at the wing bridge platform plate 106 and the stern surrounding wall 107 are thick and high in strength, the bow hanging row 103 is arranged on the wing bridge platform plate 106, the stern hanging row 104 is arranged at the stern surrounding wall 107, the fixing effect of the hanging rows can be guaranteed to be good, and the plate materials at the positions are not prone to being damaged by stress.

Generally, an upper trolley and a lower trolley are respectively arranged on a main beam of each portal crane, and when the upper trolley and the lower trolley run along a track of the main beam, the upper trolley and the lower trolley do not interfere with each other due to different height positions. However, for two gantry cranes with the same specification, the two upper trolleys are consistent in height, and the two lower trolleys are consistent in height. And the upper trolley is provided with two lifting hooks which are respectively positioned at two sides of the main beam, and the length dimension of the upper trolley along the direction of the main beam is also larger, so that the distance between the upper trolleys of the two portal cranes needs to be considered during operation.

In this embodiment, the upper trolleys of the two gantry cranes are arranged in a staggered manner, that is, the upper trolley of the first gantry crane 101 and the lower trolley of the second gantry crane 102 are arranged correspondingly, and the lower trolley of the first gantry crane 101 and the upper trolley of the second gantry crane 102 are arranged correspondingly.

Further, the distance between the upper trolleys of the two gantry cranes along the width direction of the main beam is also limited, in an optional scheme of the embodiment, the distance between the bow hanging row 103 and the stern hanging row 104, which are located on the opposite sides of the width direction of the dock and are respectively connected with the upper trolleys of the first gantry crane 101 and the second gantry crane 102, in the width direction of the dock is greater than or equal to a second limited distance; the second defined distance is the sum of half the length of the upper trolley of the first portal crane 101 in the width direction of the dock and half the length of the upper trolley of the second portal crane 102 in the width direction of the dock.

In this embodiment, the positions of the bow hanging row 103 and the stern hanging row 104 are set such that the distance between the upper trolley of the first gantry crane 101 and the upper trolley of the second gantry crane 102 is greater than or equal to the second limited distance along the width direction of the dock, thereby avoiding the interference between the upper trolleys of the two gantry cranes and further meeting the working condition requirement of crane hoisting.

Specifically, referring to fig. 1, the length of the upper trolley of the first portal crane 101 in the width direction of the dock and the length of the upper trolley of the second portal crane 102 in the width direction of the dock are both 15m, and the second defined distance is 15 m.

In an optional scheme of the embodiment, two bow hanging rows 103 are symmetrically arranged along the center line of the width direction of the ship; the two stern banks 104 are symmetrically arranged with respect to the center line in the width direction of the ship. Further, when the ship is hoisted, the stress points of the hoisting are uniformly distributed at all positions of the ship, and the stability and reliability of the hoisting process are ensured.
