Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the hoisting brace for large marine structures according to an embodiment of the present invention includes a brace assembly 10, two shackle rods 20, two shackle plates 30, two first shackles 40, and two second shackles 50.
Two shackle rods 20 are detachably connected to opposite ends of the stay bar assembly 10, respectively. The shackle plate 30 has first and second opposite ends, the first end of which is pivotally coupled to the shackle rod 20 so as to be pivotable relative to the shackle rod 20 for angular adjustment. A first shackle 40 is connected to the second ends of the shackle rod member 20 and the shackle plate member 30 for rotatably connecting the second ends of the shackle rod member 20 and the shackle plate member 30, the first shackle 40 also being adapted to be connected to a crane. A second shackle 50 is attached to a second end of the shackle plate 30 for suspending a structure.
The length of the stay bar assembly 10 is variable, and the required length can be adjusted according to the size of a structure to be hoisted. The removable connection of the shackle rods 20 to the brace assembly 10 allows the brace assembly 10 to be connected for use or removed as needed.
The utility model discloses a marine large structure thing hoist and mount vaulting pole is at first user state, and 10 axial connections of vaulting pole subassembly are between two lug rod pieces 20, form the main part of hoist and mount vaulting pole with lug rod piece 20. In the second use state, the stay bar assembly 10 is disengaged from the shackle rods 20, and the two shackle rods 20 are axially connected in opposition to form the main body of the hoisting stay bar.
Understandably, according to the structure size of hoist and mount, the utility model discloses a marine large-scale structure hoist and mount vaulting pole can have multiple user state, and the main part of each user state corresponds the structure of hoist and mount and has corresponding required length.
To facilitate the connection and the removal of the shackle stem 20 and brace assembly 10, the two may be flanged, etc. In this regard, in this embodiment, the hoisting stay further includes a first connecting flange 61 disposed on the end surface of the opposite ends of the stay assembly 10, and a second connecting flange 70 disposed on the end surface of the corresponding end of the shackle stem 20. The first connecting flange 61 and the second connecting flange 62 are respectively provided with connecting holes which can be communicated relatively, and are locked in the communicated connecting holes through bolts, so that the connecting flanges which are matched relatively are connected together, and the requirement on structural strength can be met. When the hoisting stay bar is in the first use state, the first connecting flange 61 and the second connecting flange 62 are oppositely matched and locked through bolts. When the hoisting stay bar is in the second use state, the second connecting flanges 62 of the two lifting lug rods 20 are oppositely matched and locked through bolts.
In addition, in order to facilitate the placement and positioning of the hoisting stay, the side planes of the same side of the first connecting flange 61 and the second connecting flange 62 are arranged to form a support surface which can be horizontally placed on the deck of the ship, such as the lower sides of the first connecting flange 61 and the second connecting flange 62 shown in fig. 1.
Specifically, in the present invention, the stay bar assembly 10 may include a first bar 11, and at least one second bar 12 detachably connected to at least one end of the first bar 11. The length of the first pin 11 is greater than the length of the second pin 12.
In the strut assembly 10, by connecting the second rods 12 to one end or both ends of the first rod 11, the second rods 12 connected to each end may be axially connected to one or more ends, thereby adjusting and obtaining the strut assembly 10 having a desired length.
The connection between the first pole 11 and the second pole 12 can also be realized by a flange connection. For example, the third connecting flange 63 is provided at the end of the first rod 11, the fourth connecting flange 64 is provided at the end of the second rod 12, and when the first rod 11 and the second rod 12 are connected, the third connecting flange 63 and the fourth connecting flange 64 are relatively engaged and locked by bolts.
