Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a quick connection device for offshore steel structure frames. Background Technology

[0002] In many engineering fields, especially in scenarios involving underwater operations or requiring specific component connections, the connection between components is a crucial element. Currently, there are two main common methods for component connection. One is fixing with bolts. This method uses bolts to pass through pre-drilled holes in the components, and then tightens them with nuts. The preload generated by the threaded engagement between the bolt and nut ensures that the components fit tightly together, thus achieving the connection. The other method is welding. This method uses high temperatures to melt and fuse the metal materials at the connection points, forming a robust connection structure. This method is widely used in applications requiring high connection strength.

[0003] However, both existing connection methods have significant drawbacks. Bolted connections are cumbersome, requiring precise alignment of the bolt holes on the components during installation; even slight deviations can hinder successful installation. Furthermore, tightening each bolt individually is time-consuming and labor-intensive. During later maintenance or disassembly, bolt rust or corrosion can cause difficulties and even damage to components. While welding offers higher connection strength, it is extremely difficult to perform underwater. Underwater welding causes rapid solidification due to water cooling, easily leading to defects such as porosity and cracks. Low visibility and limited operating space further increase the difficulty and risk of welding operations, demanding extremely high levels of skill from welders and advanced equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quick connection device for marine steel structure frames, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick connection device for a marine steel structure frame, comprising steel column A and steel column B, wherein a female head is provided at the upper end of steel column A and a male head adapted to the female head is provided at the lower end of steel column B.

[0006] The male connector includes a plug post, and the outer wall of the plug post is provided with an annular groove.

[0007] The female connector includes a column with a plug groove adapted to the plug post inside. The inner wall of the plug groove has several limiting grooves. A locking block is horizontally embedded and slidably installed in the limiting groove. One end of the locking block has an inclined structure and extends out of the limiting groove. The other end of the locking block is connected to the inner wall of the limiting groove by a spring. The outside of the column is provided with a disassembly component for separating the male and female connectors.

[0008] Preferably, after the plug is fully inserted into the plug groove on the column, the annular groove on the plug corresponds exactly to the locking block. At this time, the spring is in the reset state, and the inclined surface of the locking block is inserted into the annular groove.

[0009] Preferably, the disassembly component includes an annular seat rotatably disposed outside the column, a handle is provided on one side of the annular seat, and a cavity is provided on the inner side of the annular seat. Several connecting rods corresponding to each locking block are hinged to the inner wall of the cavity, and the other end of the connecting rod is hinged to the side of the corresponding locking block.

[0010] Preferably, the outer wall of the column is provided with an annular groove corresponding to the connecting rod, the connecting rod passes through the annular groove, and the limiting groove communicates with the annular groove.

[0011] Preferably, the inner side of the annular seat is provided with flanges at the top and bottom of the cavity, and the outer side wall of the column is provided with annular guide grooves corresponding to the flanges at the top and bottom of the annular groove, and the flanges are slidably embedded in the annular guide grooves.

[0012] Preferably, both the male and female connectors are made of stainless steel.

[0013] This invention provides a quick connection device for offshore steel structure frames, which has the following advantages compared with the prior art:

[0014] This quick-connect device for offshore steel structure frames allows for easy installation. Simply insert the male connector directly into the female connector, and the two will lock together quickly, completing the connection. When disassembly is required, simply rotate the disassembly component, and steel column A and steel column B will separate instantly. This convenient connection and disassembly method completely eliminates the high difficulty of traditional welding and the cumbersome process of bolt connection. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5 This invention provides two technical solutions:

[0023] Example 1

[0024] Please see Figure 1 In this embodiment of the invention, a quick connection device for a marine steel structure frame includes a steel column A1 and a steel column B2. The upper end of the steel column A1 is provided with a female head 4, and the lower end of the steel column B2 is provided with a male head 3 that is compatible with the female head 4.

[0025] Please see Figure 2 In this embodiment of the invention, the male connector 3 includes a plug post 31, and the outer side wall of the plug post 31 is provided with an annular groove 32.

[0026] Please see Figure 3 and Figure 4 In this embodiment of the invention, the female connector 4 includes a column 41, and the column 41 is provided with a plug groove 42 adapted to the plug post 31. The inner wall of the plug groove 42 is provided with a plurality of limiting grooves 43. A locking block 44 is slidably installed in the limiting groove 43. One end of the locking block 44 has an inclined structure and extends out of the limiting groove 43. The other end of the locking block 44 is connected to the inner wall of the limiting groove 43 by a spring 45. The outside of the column 41 is provided with a disassembly component for separating the male connector 3 and the female connector 4.

[0027] Please see Figure 4 In this embodiment of the invention, after the plug-in post 31 is fully inserted into the plug-in groove 42 on the post 41, the annular groove 32 on the plug-in post 31 corresponds exactly to the locking block 44. At this time, the spring 45 is in the reset state, and the inclined surface of the locking block 44 is inserted into the annular groove 32.

[0028] In the above scheme: a crane is used to lift the steel column B2, and the male end 3 of the lower end of the steel column B2 is inserted into the female end 4, that is, the plug-in post 31 is inserted into the plug-in groove 42 on the column body 41. When the lower end of the plug-in post 31 passes the locking block 44, it will press the inclined surface of the locking block 44. Under the elasticity of the spring 45, the locking block 44 will move into the limiting groove 43. Then the plug-in post 31 continues to move down. When the plug-in post 31 is fully inserted into the plug-in groove 42, the annular locking groove 32 on the plug-in post 31 corresponds exactly to the locking block 44. At this time, the spring 45 resets the locking block 44, and the locking block 44 will insert into the annular locking groove 32, locking the plug-in post 31 and completing the installation work.

[0029] Example 2 adds a disassembly component to Example 1, as detailed below:

[0030] Please see Figures 3-5 In this embodiment of the invention, the disassembly component includes an annular seat 46 rotatably disposed outside the column 41. A handle 47 is provided on one side of the annular seat 46, and a cavity 48 is provided on the inner side of the annular seat 46. A plurality of connecting rods 49 corresponding to each locking block 44 are hinged to the inner wall of the cavity 48. The other end of the connecting rod 49 is hinged to one side of the corresponding locking block 44.

[0031] Please see Figures 3-5 In this embodiment of the invention, the outer wall of the column 41 is provided with an annular groove 4101 corresponding to the connecting rod 49, the connecting rod 49 passes through the annular groove 4101, and the limiting groove 43 communicates with the annular groove 4101.

[0032] In the above scheme: when it is necessary to separate steel column A1 and steel column B2, turn handle 47 to drive the ring seat 46 to rotate, the ring seat 46 drives the connecting rod 49 to move, and under the elasticity of spring 45, the other end of the connecting rod 49 will pull the locking block 44 to move in the limiting groove 43, so that the locking block 44 is disengaged from the annular locking groove 32 on the plug-in column 31. Then the crane will lift steel column B2 directly, so that the plug-in column 31 leaves the plug-in groove 42 on the column body 41, thereby completing the separation operation.

[0033] For further details, please refer to Figure 3 In this embodiment of the invention, the inner side of the annular seat 46 is provided with flanges 461 above and below the cavity 48, and the outer side wall of the column 41 is provided with annular guide grooves 4102 corresponding to the flanges 461 above and below the annular groove 4101. The flanges 461 are slidably embedded in the annular guide grooves 4102. When the annular seat 46 rotates, the flanges 461 will slide in the annular guide grooves 4102, which plays a guiding and limiting role for the annular seat 46.

[0034] For further details, please refer to [link / reference]. Figure 4 In this embodiment of the invention, both the male connector 3 and the female connector 4 are made of stainless steel to prevent rusting.

[0035] Working principle: The steel column B2 is lifted by a crane. The male end 3 of the lower end of the steel column B2 is inserted into the female end 4, that is, the plug-in column 31 is inserted into the plug-in groove 42 on the column body 41. When the lower end of the plug-in column 31 passes the locking block 44, it will press the inclined surface of the locking block 44. Under the elasticity of the spring 45, the locking block 44 will move into the limiting groove 43. Then the plug-in column 31 continues to move down. When the plug-in column 31 is fully inserted into the plug-in groove 42, the annular locking groove 32 on the plug-in column 31 corresponds exactly to the locking block 44. At this time, the spring 45 resets the locking block 44, and the locking block 44 will insert into the annular locking groove 32, locking the plug-in column 31 and completing the installation work.

[0036] When it is necessary to separate steel column A1 and steel column B2, turn handle 47 to drive the ring seat 46 to rotate. The ring seat 46 drives the connecting rod 49 to move. Under the elasticity of spring 45, the other end of the connecting rod 49 will pull the locking block 44 to move in the limiting groove 43, so that the locking block 44 is disengaged from the annular locking groove 32 on the plug-in column 31. Then the crane will lift steel column B2 directly, so that the plug-in column 31 is separated from the plug-in groove 42 on the column body 41, thereby completing the separation operation.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
