Description

Technical Field

[0001] The invention relates to the technical field of marine engineering equipment, and in particular to a riveted pin connection device for connecting a large floating body which can be quickly assembled and disassembled and dynamically adjusted. Background Art

[0002] The tourism floating complex is an important tool for humans to stay in the ocean and develop the marine economy. It can be quickly deployed and moored in important national marine strategic waters or international waters, serving the national marine power strategy. The multi-module configuration of the tourism floating complex is complex and huge in size. It needs to be composed of multiple large floating modules. The connection interface of each floating module needs to be connected by a connection system composed of multiple connectors to connect them together. It is intended to solve the problems of engineering design and construction, marine transportation, and engineering installation of super-large and super-long structures.

[0003] At present, there are two main types of floating platform connection devices: rigid connectors and flexible connectors. Rigid connectors are mainly realized by hinges, and flexible connectors are mainly realized by mooring. Both of the above two types of connectors release the relative freedom between the two floating platform modules and cannot achieve fixed connection.

[0004] The floating module connection system is subjected to the load of wind, wave, current and ocean environment at sea for a long time, which causes the connection system between the connection interfaces to generate extremely high-intensity forces. The material performance characteristics of the metal materials used in the fixed connector, the objective existence of problems such as material strength, structural rigidity, elastic deformation and plastic deformation, often cause the connector to be subjected to large load forces under the combined bending and torsion of wind, wave, current and ocean environment loads at sea, which can easily cause the connector to bear excessive load forces and produce plastic deformation damage.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention.

[0019] Figure 2 for Figure 1 AA section diagram. DETAILED DESCRIPTION

[0020] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, a riveted pin connection device for connecting large floating bodies that can be quickly assembled and disassembled and dynamically adjusted in load includes a first bearing 11 arranged on a first floating body 10 and a second bearing 12 arranged on a second floating body 20.

[0022] There is a first gap between the first bearing 11 and the second bearing 12. A limiting component (not shown in the figure) is provided on the end surface of the first floating body where the first bearing is located or on the end surface of the second floating body where the second bearing is located. When the first floating body and the second floating body are close to each other, due to the existence of the limiting component, there is a first gap between the first bearing and the second bearing.

[0023] The second floating body is provided with a pin 30. The tail of the pin 30 is connected with a first telescopic mechanism 21 which can extend or retract the pin. The first telescopic mechanism 21 is located on the second floating body 20.

[0024] The pin shaft 30 is inserted through both the second bearing 12 and the first bearing 11 .

[0025] There is a second gap between the pin 30 and the inner wall of the second bearing 12. The pin and the second bearing can move relative to each other within the range of the second gap, which can alleviate the influence of the external sea conditions of the floating body to a certain extent and avoid the pin being subjected to excessive force immediately.

[0026] The pin 30 has an extension section extending to the outside of the first bearing, the extension section is close to the head of the pin, a locking hole 34 is formed on the extension section, and a locking shaft 35 is passed through the locking hole 34.

[0027] The tail of the locking shaft 35 is connected to a second telescopic mechanism 22 which can extend or retract the locking shaft.

[0028] The locking shaft 35 is located outside the first bearing. The locking shaft 35 and the second telescopic mechanism 22 are both arranged on the first floating body 10.

[0029] A third gap is provided between the locking shaft 35 and the locking hole 34 for the pin to move in the direction of the central axis of the pin.

[0030] The upper side and the lower side of the locking shaft 35 are both planes. Like this, it is convenient for the axial movement of the pin.

[0031] The surface of the locking shaft close to the first bearing is the right side surface of the locking shaft; the right side surface of the locking shaft is a plane; the surface of the locking shaft close to the pin head is the left side surface of the locking shaft; the left side surface of the locking shaft is a tapered curved surface.

[0032] Since there is a third gap between the locking shaft 35 and the locking hole 34 , when the locking shaft is inserted into the locking hole, the pin shaft can move axially within the range of the third gap under the action of the first telescopic mechanism.

[0033] The riveted pin connection device for large floating body connection that can be quickly assembled and disassembled and dynamically adjusted in load also includes a pin stress detection device (not shown in the figure); the force measuring end 51 of the pin stress detection device is embedded in the inner wall of the second bearing 12.

[0034] The pin stress detection device has multiple force measuring ends 51 , and the multiple force measuring ends 51 are distributed in a ring shape along the inner wall of the second bearing 12 .

[0035] The shape of the pin can be in various forms.

[0036] In this embodiment, the pin 30 includes a pin body 31, and the tail of the pin body 31 is connected to a conical portion 32; the head of the conical portion is connected to the tail of the pin body; the outer diameter of the head of the conical portion 32 is the same as the outer diameter of the tail of the pin body 31; the outer diameter of the tail of the conical portion 32 is larger than the outer diameter of the head of the conical portion 32.

[0037] The pin body 31 is inserted into the first bearing 11. The inner cavity of the first bearing 11 is cylindrical. The truncated cone portion 32 is inserted into the second bearing 12. The inner cavity of the second bearing 12 is truncated cone-shaped.

[0038] In order to facilitate manufacturing and improve the strength of the pin shaft itself, the pin shaft body and the truncated cone portion are integrally formed. The head of the pin shaft is an arc end, so that the pin shaft is easy to insert into the first bearing or pull out from the first bearing.

[0039] Under the action of the second telescopic mechanism 22, the locking shaft 35 can be extended and inserted into the locking hole 34. Under the action of the second telescopic mechanism 22, the locking shaft 35 can also be retracted and disengaged from the locking hole 34. When the locking shaft is disengaged from the locking hole, the pin can be retracted and disengaged from the first bearing.

[0040] In this embodiment, the first telescopic mechanism and the second telescopic mechanism are both hydraulic mechanisms. The hydraulic mechanism includes a hydraulic cylinder, and the hydraulic cylinder has a telescopic piston. The piston of the first telescopic mechanism is connected to the pin shaft, and the piston of the second telescopic mechanism is connected to the locking shaft.

[0041] The separation and docking process of this connection device: when the first floating body and the second floating body are separated, the locking shaft disengages from the locking hole, and the first telescopic mechanism applies a retracting force on the pin shaft to gradually pull the pin shaft out of the first bearing until the arc end completely slides out of the first bearing, completing the separation of the first floating body and the second floating body. The truncated cone portion of the pin shaft has a positive effect on the pulling out of the pin shaft. When the first floating body and the second floating body are docked, since the pin shaft has an arc end, it can play a guiding role, and the first telescopic mechanism at the tail of the pin shaft applies a thrust, so that the pin shaft can quickly enter the first bearing until it is fully inserted, completing the docking of the first floating body and the second floating body; the locking shaft is inserted into the locking hole. This connection device can achieve quick docking and quick separation.

[0042] The locking and unlocking process of the connection device is as follows: when the pin shaft is fully inserted into the first bearing, the second telescopic mechanism applies a thrust to the locking shaft, and the locking shaft is inserted into the locking hole of the pin shaft to lock the pin shaft, thereby achieving a fixed connection between the first floating body and the second floating body. When unlocking is required, the second telescopic mechanism applies a retracting force to the locking shaft, and the locking shaft slowly disengages from the locking hole until the locking shaft is completely disengaged from the pin shaft, completing the unlocking of the connection device.

[0043] Locking connection load adjustment process: When the external sea conditions of the floating body are relatively small, the pin shaft and the first bearing are in a fully matched state, and the locking shaft also enters the locking hole of the pin shaft, which is in an unadjusted state; as the external sea conditions gradually become worse, when the pin shaft stress detection equipment detects that the force value of the pin shaft is close to the set value, the first telescopic mechanism applies force to the pin shaft to make the pin shaft retreat within the set adjustment range. Since the truncated cone of the pin shaft has a taper, the force of the pin shaft can be accurately controlled according to the retreat amount of the pin shaft, thereby achieving the effect of accurately adjusting the pin shaft bearing force. Since there is a third gap between the locking shaft and the locking hole, the locking shaft will not affect the movement of the pin shaft.

[0044] In this way, the force on the pin can be accurately controlled, so that the pin as the main load-bearing component is in a safe working state, and is neither affected by the movement of the floating body nor affects the locking of the pin by the locking shaft.

[0045] The rivet pin connection device for connecting large floating bodies capable of rapid assembly and disassembly and dynamic load adjustment of the present invention can realize non-freedom fastening when connecting large floating bodies, can fasten and quickly connect multiple large floating bodies together, and can be used in offshore engineering applications such as rapid docking connection and rapid disassembly and release.

[0046] With respect to a connection system composed of multiple connectors between connection interfaces, due to the material performance characteristics of the metal material of the connector axle pin, under the combined bending and torsion of wind, waves, currents and marine environmental loads at sea, the outer connector is very likely to be damaged due to excessive bearing force. The present invention solves the problem of dynamic adjustment of the super-large bearing force of multiple connectors arranged in parallel on the connection interface, so as to avoid plastic deformation damage caused by excessive bearing force on the axle pin of the outer connector.

[0047] 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.
