Description

Technical Field

[0001] The invention relates to the technical field of pontoons, and in particular to an offshore assembled pontoon using a rigid connection device. Background Art

[0002] The offshore assembled pontoon was first used by the US Navy in the pier system.

[0053] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0054] Figure 1 It shows an offshore assembled pontoon comprising a first pontoon 1 and a second pontoon 2 arranged in a transverse direction; Figure 4 The offshore assembled pontoon is shown, which includes a first pontoon 1 and a third pontoon 3 arranged in the longitudinal direction. In this embodiment, only the first pontoon 1 and the second pontoon 2 are used as examples to explain in detail the specific structure of connecting the pontoons arranged in the transverse direction through the longitudinal socket and the longitudinal plug 6. At the same time, only the first pontoon 1 and the third pontoon 3 are used as examples to explain in detail the specific structure of connecting the pontoons arranged in the longitudinal direction through the transverse plug 10. The longitudinal socket and the longitudinal plug 6 can be used not only to connect the pontoons arranged in the transverse direction, but also to connect the pontoons arranged in the longitudinal direction. Similarly, the transverse socket can be used not only to connect the pontoons arranged in the longitudinal direction, but also to connect the pontoons arranged in the transverse direction. The assembled pontoon can include a plurality of pontoons distributed in an array.

[0055] like Figure 1 As shown in the structure, the embodiment of the present invention provides an offshore assembled pontoon using a rigid connection device, including a first pontoon 1, a second pontoon 2, a longitudinal socket and a longitudinal plug 6; the first pontoon 1 and the second pontoon 2 are arranged in a transverse direction;

[0056] At least two longitudinal sockets are fixedly mounted on the surface of one side of the first pontoon 1 facing the second pontoon 2, and the at least two longitudinal sockets are arranged at intervals to form a receiving space 7 for the longitudinal plug 6 between two adjacent longitudinal sockets; the longitudinal sockets are provided with a plurality of first connecting holes 8 on the side facing the receiving space 7; the longitudinal sockets may include longitudinal side sockets 4 installed on both sides of the first pontoon 1 and at least one longitudinal middle socket 5 located between the two longitudinal side sockets 4; Figure 2 and Figure 3 As shown in the structure, two longitudinal side sockets 4 and two longitudinal middle sockets 5 are arranged on the first buoyancy box 1; Figure 4 As shown in the structure, only three longitudinal middle sockets 5 may be provided on the first buoyancy box 1;

[0057] A longitudinal plug 6 corresponding to each of the accommodating spaces 7 is fixedly mounted on the surface of the second pontoon 2 facing the first pontoon 1, and the longitudinal plug 6 is inserted into the accommodating space 7; Figure 1 As shown in the structure, when two longitudinal side sockets 4 and two longitudinal middle sockets 5 are provided on the first pontoon 1, three accommodating spaces 7 are formed between the longitudinal side sockets 4, and three longitudinal plugs 6 are provided on the second pontoon 2; first plugs 9 corresponding to the first connecting holes 8 are provided on both sides of the longitudinal plugs 6; the projection of the accommodating space 7 on the horizontal plane can be trumpet-shaped, and the trumpet-shaped opening is arranged toward the second pontoon 2;

[0058] The first latch 9 can enter the retracted state from the extended state when subjected to an external force; when the first latch 9 is in the extended state, the first latch 9 is inserted into the corresponding first connection hole 8 to splice the first pontoon 1 and the second pontoon 2 together; when the first latch 9 is in the retracted state, the first latch 9 is retracted into the inner side of the longitudinal plug 6, and the first pontoon 1 is separated from the second pontoon 2. The first latch 9 is in the extended state in the natural state. When the first latch 9 is subjected to an external force, the first latch 9 elastically expands and contracts under the action of the external force, and retracts from the outer side of the longitudinal socket to the inner side of the longitudinal socket, thereby realizing the unlocking between the two pontoons.

[0059] The above-mentioned offshore assembled pontoon adopts a longitudinal plug 6 and a longitudinal socket that are plug-in matched to form a rigid connection device, and a accommodating space 7 for the longitudinal socket to be plugged in is formed between the longitudinal sockets arranged on the first pontoon 1, and a first connecting hole 8 is arranged on the longitudinal socket. The first pin 9 of the longitudinal socket corresponds to the first connecting hole 8 one by one. When the longitudinal plug 6 enters the accommodating space 7, the first pin 9 can automatically enter the corresponding first connecting hole 8 to realize the connection between the longitudinal socket and the longitudinal plug 6, and then realize the connection between the first pontoon 1 and the second pontoon 2. The first pontoon 1 and the second pontoon 2 can be automatically preliminarily docked through the collision of the longitudinal plug 6 and the longitudinal socket, which can adapt to complex sea conditions, reduce the difficulty of operation, and improve the stress condition of the pontoon.

[0060] In a specific embodiment, the above-mentioned offshore assembled pontoon further includes a third pontoon 3 and a transverse plug 10 for connecting the first pontoon 1 and the third pontoon 3; the arrangement direction of the first pontoon 1 and the second pontoon 2 is perpendicular to the arrangement direction of the first pontoon 1 and the third pontoon 3; that is, Figure 1 and Figure 4 As shown in the structure, when the first pontoon 1 and the second pontoon 2 are arranged in the transverse direction, the first pontoon 1 and the third pontoon 3 are arranged in the longitudinal direction;

[0061] A plurality of first slots 11 are provided on a surface of one side of the first buoyancy box 1 facing the third buoyancy box 3, and a plurality of second connection holes (not shown in the figure) are provided on both sides of the first slots 11;

[0062] A second slot 12 (not shown in the figure) corresponding to the first slot 11 is provided on one side of the third buoyancy box 3 facing the first buoyancy box 1, and a plurality of third connection holes (not shown in the figure) are provided on both sides of the second slot 12;

[0063] The transverse plug 10 is accommodated in the corresponding first slot 11 and second slot 12 in a shape-matched manner, and is provided with a second plug (not shown in the figure) corresponding to the second connection hole one by one and a third plug (not shown in the figure) corresponding to the third connection hole one by one;

[0064] When subjected to external force, the second latch and the third latch can both move from an extended state to a retracted state; when the second latch and the third latch are in the extended state, the second latch is inserted into the corresponding second connecting hole, and the third latch is inserted into the corresponding third connecting hole, so that the first pontoon 1 and the third pontoon 3 are spliced ​​together; when the second latch and the third latch are in the retracted state, the second latch and the third latch are both retracted into the inner side of the transverse plug 10, so that the first pontoon 1 and the third pontoon 3 are separated.

[0065] By providing a second slot 12 on the first pontoon 1 and a third slot on the third pontoon 3, when the first pontoon 1 and the second pontoon 2 are connected together, the second slot 12 of the first pontoon 1 and the third slot of the third pontoon 3 are opposite to each other and form a space for accommodating the transverse plug 10. The second pin on the transverse plug 10 is plugged into the second connecting hole of the first pontoon 1, and the third pin is plugged into the third connecting hole of the third pontoon 3. The connection between the first pontoon 1 and the third pontoon 3 is achieved through the pin on the transverse plug 10, thereby achieving the connection between the first pontoon 1 and the third pontoon 3. The connection structure is simple and convenient. Similarly, the automatic connection between the first pontoon 1 and the third pontoon 3 can be achieved through the second pin and the third pin.

[0066] like Figure 5 As shown in the structure, the longitudinal plug 6 also includes a slot frame 13 and a first transmission shaft 14; the slot frame 13 is fixedly mounted on the second buoyancy tank 2, matches the shape of the accommodating space 7, and is provided with a first through hole 15 corresponding to the first connecting hole 8 one by one; Figure 6 A specific structure of a channel frame 13 is shown;

[0067] The first transmission shaft 14 is provided with an axis line in the vertical direction, and can be rotatably installed on the groove frame 13 around the axis line. First locking pins 16 for locking the first transmission shaft 14 are provided at both ends; the first transmission shaft 14 can be unlocked and locked by the first locking pins 16. When the first transmission shaft 14 is unlocked, the first latch 9 can be controlled by rotating the first transmission shaft 14, so that the first latch 9 is in an extended state or a retracted state;

[0068] A first cam 17 corresponding to the first through hole 15 is fixedly installed on the first transmission shaft 14 in the groove frame 13; each first cam 17 is provided with two first arc-shaped slide grooves 18, and a first pin shaft 19 parallel to the first transmission shaft 14 is installed in each first arc-shaped slide groove 18, and the first pin shaft 19 can slide along the first arc-shaped slide groove 18; a first latch 9 is fixed on each first pin shaft 19; the first cam 17 is used to convert the rotation of the first transmission shaft 14 into a radial linear motion of the first pin shaft 19 in the first transmission shaft 14, and drive the first latch pin 9 to extend or retract into the groove frame 13 through the first through hole 15 to realize the connection between the first pontoon 1 and the second pontoon 2.

[0069] like Figure 7 As shown in the structure, a plurality of first cams 17 are arranged on the first transmission shaft 14, and an axial hole 24 for penetrating the first transmission shaft 14 is arranged on the first cam 17. The first cam 17 and the first transmission shaft 14 can be connected by a flat key. The first cam 17 includes two relatively fixed cam discs, and two first arc-shaped slide grooves 18 are arranged on each cam disc. A first pin 19 is assembled in the first arc-shaped slide grooves 18 of the two cam discs, and the first pin 19 can slide along the first arc-shaped slide groove 18. The first cam 17 is two axially spaced apart and arranged along the first transmission shaft 14, and is fixedly installed on the first pin 19. There is a first latch 9; when the first transmission shaft 14 rotates, the first latch 9 is limited by the first through hole 15 and cannot rotate with the first transmission shaft 14, so that the first arc-shaped slide groove 18 rotates relative to the first pin shaft 19, and the first pin shaft 19 is driven by the first arc-shaped slide groove 18 to move axially along the first pin shaft 19, so as to realize the axial reciprocating motion of the first latch 9, so that the connection and unlocking between the first pontoon 1 and the second pontoon 2 are realized through the cooperation of the first latch 9 and the first connecting hole 8; therefore, the connection between the first pontoon 1 and the second pontoon 2 can be controlled by the first transmission shaft 14, which facilitates the disassembly and assembly between the pontoons.

[0070] like Figure 7 As shown in the structure, the first latch 9 includes a first pin rod 20 fixedly connected to the first pin shaft 19, a first pin cap 21 that can be slidably installed on the first pin rod 20, and a first spring 22 sleeved on the first pin rod 20; the first spring 22 is located between the first pin shaft 19 and the first pin cap 21, and is used to push the first pin cap 21 to move in a direction away from the first pin shaft 19; the first pin cap 21 is used to pass through the corresponding first through hole 15 and the first connecting hole 8 to connect the first buoyancy box 1 and the second buoyancy box 2 together.

[0071] By providing a first spring 22 between the first pin shaft 19 and the first pin cap 21, the first pin cap 21 can always have a tendency to move in a direction away from the first pin shaft 19. Therefore, the first pin shaft 19 can automatically pop out of the groove frame 13 and enter the first connecting hole 8 of the longitudinal socket, thereby facilitating the connection between the longitudinal plug 6 and the longitudinal socket, making the connection between the first pontoon 1 and the second pontoon 2 simple and quick, and reducing the difficulty of connecting the pontoons.

[0072] like Figure 8 As shown in the structure, the transverse plug 10 also includes a cylindrical frame, a second transmission shaft and a third transmission shaft; in the actual production process, the cylindrical frame can be composed of two groove frames 13 arranged opposite to each other and fixedly connected together, that is, the transverse plug 10 can be composed of two longitudinal plugs 6 butted together; the cylindrical frame can be a hexagonal prism structure;

[0073] The cylindrical frame is provided with a second through hole 25 corresponding to the second connection hole one by one and a third through hole 23 corresponding to the third connection hole one by one; the second transmission shaft and the third transmission shaft are both arranged in the vertical direction and can be rotatably mounted on the cylindrical frame, and the two ends of the second transmission shaft are provided with a second locking pin for locking, and the two ends of the third transmission shaft are provided with a third locking pin for locking;

[0074] A second cam corresponding to the second through hole 25 is fixedly mounted on the second transmission shaft in the cylindrical frame; each second cam is provided with two second arc-shaped slide grooves, and a second pin shaft parallel to the second transmission shaft is installed in each second arc-shaped slide groove, and the second pin shaft can slide along the second arc-shaped slide groove;

[0075] A third cam corresponding to the third through hole 23 is fixedly mounted on the third transmission shaft in the cylindrical frame; each third cam is provided with two third arc-shaped slide grooves, and a third pin shaft parallel to the third transmission shaft is installed in each third arc-shaped slide groove, and the third pin shaft can slide along the third arc-shaped slide groove;

[0076] A second latch is fixed on each second pin shaft, and a third latch is fixed on each third pin shaft;

[0077] The second cam is used to convert the rotation of the second transmission shaft into the linear motion of the second pin in the radial direction of the second transmission shaft, driving the second latch to extend or retract into the cylindrical frame through the second through hole 25; the third cam is used to convert the rotation of the third transmission shaft into the linear motion of the third pin in the radial direction of the third transmission shaft, driving the third latch to extend or retract into the cylindrical frame through the third through hole 23.

[0078] Similarly, the second latch and the third latch can adopt the same structure as the first latch 9. The second latch includes a second pin rod fixedly connected to the second pin shaft, a second pin cap slidably mounted on the second pin rod, and a second spring sleeved on the second pin rod; the second spring is located between the second pin shaft and the second pin cap, and is used to push the second pin cap to move in a direction away from the second pin shaft; the second pin cap is used to pass through the corresponding second through hole 25 and the second connecting hole to connect the first buoyancy box 1 transverse plug 10 together.

[0079] The third latch includes a third pin rod fixedly connected to the third pin shaft, a third pin cap slidably installed on the third pin rod, and a third spring sleeved on the third pin rod; the third spring is located between the third pin shaft and the third pin cap, and is used to push the third pin cap to move in a direction away from the third pin shaft; the third pin cap is used to pass through the corresponding third through hole 23 and the third connecting hole to connect the third buoyancy box 3 transverse plug 10 together.

[0080] like Figure 2 and Figure 3 As shown in the structure, the longitudinal socket includes longitudinal side sockets 4 installed on both side edges of the first pontoon 1 and at least one longitudinal middle socket 5 located between the two longitudinal side sockets 4. The number of longitudinal middle sockets 5 can be determined according to the size of the pontoon; when the longitudinal socket includes one longitudinal middle socket 5, an accommodating space 7 is formed between the longitudinal side socket 4 and the longitudinal middle socket 5; when the longitudinal socket includes at least two longitudinal middle sockets 5, an accommodating space 7 is formed between the longitudinal side socket 4 and the longitudinal middle socket 5, and between adjacent longitudinal middle sockets 5; the longitudinal side socket 4 is provided with a plurality of first connecting holes 8 on a side surface facing the longitudinal middle socket 5; the longitudinal middle socket 5 is provided with a plurality of first connecting holes 8 on both side surfaces facing the longitudinal side socket 4.

[0081] The specific connection process of the above-mentioned offshore assembled pontoon is as follows: when connecting the first pontoon 1 and the second pontoon 2, the first pontoon 1 is moved toward the second pontoon 2 or the second pontoon 2 is moved toward the first pontoon 1, the accommodating space 7 between the longitudinal plug 6 and the longitudinal socket is opposite, and the longitudinal plug 6 is inserted into the accommodating space 7, the first latch 9 is extended outward under the action of the spring, and when the longitudinal plug 6 contacts the longitudinal socket, the first latch 9 is retracted into the groove frame 13 under the collision of the longitudinal plug 6 and the longitudinal socket, when the first latch 9 corresponds to the position of the first connecting hole 8, the first latch 9 is ejected and penetrated into the first connecting hole 8 of the longitudinal socket under the action of the spring, and the initial connection of the first pontoon 1 and the second pontoon 2 is realized, and the first transmission shaft 14 is operated to rotate, so that the first cam 17 drives the first latch 9 to continue to extend outward to the position, so that the first pontoon 1 and the second pontoon 2 are reliably connected, and then the first locking pin 16 is locked to complete the connection between the first pontoon 1 and the second pontoon 2. The disassembly of the first pontoon 1 and the second pontoon 2 is opposite to the above-mentioned connection process. The installation and disassembly process between the first pontoon 1 and the third pontoon 3 is similar to the installation and disassembly process between the first pontoon 1 and the second pontoon 2 .
