[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 5 As 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 fixedly arranged at the lower end of the bracket body 12. The connecting plate 20 is penetrated 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 shaft 41. The first pin shaft 41 is detachably disposed 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 penetrated 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 , and the two first reinforcement rings 51 are respectively disposed on both sides of the connection plate 20 . The first pin shaft 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 shaft 42. The second pin shaft 42 is a circular pin shaft.
[0030] The second pin shaft 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 connection seat 32 . The two second reinforcement rings 52 are respectively disposed on two sides of the connection plate 20 .
[0032] The second pin shaft 42 passes through the second reinforcement ring 52 and the connecting plate 20 .
[0033] The inner side of the first reinforcement ring 51 and the inner side of 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 shaft 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 form a connecting kit; a connecting kit is provided on each side of the bracket body 12. Two strip holes are provided on the deck. The two strip holes accommodate two connecting plates respectively. A supporting panel is provided on each side of the bottom of the bracket body. Two connecting kits are provided, so that the structure can be more stable.
[0038] In normal use, the bracket body is hoisted above the strip hole of the deck by the deck crane, the connecting plate is inserted into the first connecting seat and the second connecting seat after passing through the strip hole of the deck, and the supporting panel is abutted against the deck; the first pin shaft and the second pin shaft are respectively inserted into the first connecting seat and the second connecting seat, the first pin shaft is inserted through the first connecting seat and the connecting plate, and the second pin shaft is inserted through the second connecting seat and the connecting plate. At this time, the bracket body is stably erected on the deck, which can meet the daily storage needs of the shipowner.
[0039] In normal use, the support panel makes the vertical force act evenly on the deck, effectively reducing the shear force on the first and second pins; the reinforcement ring in the component can not only effectively transmit the lateral force to the structural member, but also has a guiding function. The first pin adopts a square pin, which is more conducive to the fixity of the structure.
[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 the 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 after being detached from the deck, the flatness of the deck can be ensured.
[0043] The mechanism of the present invention can be erected to meet the daily storage needs of the shipowner; the bracket body can also be placed flat on the deck to facilitate loading operations; the bracket body can also be moved away from the ship or placed in other positions on the ship that do not affect the loading of cargo. After the bracket body is placed flat on the deck or detached from the deck, the flatness of the deck can be ensured, so that the cargo area of the cargo deck is maximized.
[0044] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope 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, but these changes and modifications all fall within the protection scope of the present invention.
