[0023] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a detachable and reversible crane boom bracket connection mechanism includes a bracket body 12 arranged above a deck 10, and a connecting plate 20 is fixed to the lower end of the bracket body 12. The connecting plate 20 is passed through the deck 10.
[0025] A first connecting seat 31 and a second connecting seat 32 are fixedly provided below the deck 10 .
[0026] The connecting plate 20 and the first connecting seat 31 are connected via a first pin 41. The first pin 41 is detachably provided through the connecting plate 20 and the first connecting seat 31.
[0027] The first pin shaft 41 is a square pin shaft, and the first pin shaft 41 is simultaneously passed through the first connecting seat 31 and the connecting plate 20 .
[0028] Two first reinforcement rings 51 are fixedly disposed in the first connection seat 31 . The two first reinforcement rings 51 are respectively disposed on both sides of the connection plate 20 . The first pin 41 passes through the first reinforcement ring 51 .
[0029] The connecting plate 20 and the second connecting seat 32 are connected via a second pin 42. The second pin 42 is a circular pin.
[0030] The second pin 42 is detachably disposed through the connecting plate 20 and the second connecting seat 32 .
[0031] Two second reinforcement rings 52 are fixedly disposed in the second connecting seat 32 . The two second reinforcement rings 52 are respectively disposed on both sides of the connecting plate 20 .
[0032] The second pin 42 passes through the second reinforcement ring 52 and the connecting plate 20 .
[0033] The inner sides of the first reinforcement ring 51 and the second reinforcement ring 52 both have inclined surfaces that can play a guiding role.
[0034] The deck 10 is provided with a strip-shaped hole 11 capable of accommodating the connecting plate 20 when the bracket body rotates around the second pin 42 .
[0035] A support panel 13 is fixedly provided at the bottom of the bracket body 12 ; the support panel 13 is located above the deck 10 .
[0036] The connecting plate 20 is fixed to the bracket body 12 and the supporting panel 13 .
[0037] The connecting plate 20, the first connecting seat 31, the second connecting seat 32, the first pin 41, and the second pin 42 constitute a connecting assembly. One connecting assembly is located on each side of the bracket body 12. Two slots are provided on the deck, each accommodating a connecting plate. A support panel is located on each side of the bottom of the bracket body. The presence of two connecting assemblies provides a more stable structure.
[0038] During normal use, the bracket body is hoisted above the deck's strip-shaped hole using a deck crane. The connecting plate is inserted through the deck's strip-shaped hole and then into the first and second connecting seats, bringing the support panel into contact with the deck. The first and second pins are inserted into the first and second connecting seats, respectively. The first pin passes through the first connecting seat and the connecting plate, while the second pin passes through the second connecting seat and the connecting plate. At this point, the bracket body stands stably on the deck, meeting the shipowner's daily storage needs.
[0039] During normal use, the support panels evenly distribute vertical forces on the deck, effectively reducing shear forces on the first and second pins. The reinforcement rings in the components not only effectively transmit lateral forces to the structural members but also provide guidance. The first pin is a square pin, which further enhances structural stability.
[0040] In special loading situations, when the bracket body needs to be laid down on the deck, the first pin is pulled out and the bracket body is rotated around the second pin by crane operation. The bracket body can be rotated to a horizontal position and placed horizontally on the deck. Figure 6 shown.
[0041] When the bracket body needs to be moved away from its original position, the first pin and the second pin can be pulled out, and the bracket body can be lifted upward by a crane. The bracket body can be separated from the first connecting seat and the second connecting seat, and then the crane can lift the bracket body to the specified position.
[0042] The bracket body is placed horizontally on the deck, or detached from the deck, to ensure the flatness of the deck.
[0043] The structure of this utility model allows the bracket body to be erected to meet the daily storage needs of the shipowner; it can also be placed flat on the deck to facilitate loading operations; and it can be moved off the ship or placed in other locations on the ship that do not affect cargo loading. When the bracket body is placed flat on the deck or detached from the deck, it can ensure the flatness of the deck and maximize the cargo area of the cargo deck.
[0044] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
