Description

Technical Field

[0001] The utility model relates to the technical field of wrench tools, in particular to a dock for temporary docking of a marine trestle. Background Art

[0002] During the construction of a marine trestle, in order to speed up the construction progress, a trestle construction point is set up in the middle of the sea area, and the trestle is constructed from the sea area towards the shore. Construction workers need to take a traffic boat to land at the trestle construction point every day for trestle construction operations. During the landing process, to ensure safety, a landing platform is required for the temporary docking of the traffic boat and for the orderly boarding of the workers onto the bridge.

[0003] Currently, the commonly used landing platform is a fixed platform. The fixed platform is provided with two landing surfaces, corresponding to the low tide level and the high tide level respectively. When landing, personnel choose the landing surface according to the tide level. After the traffic boat docks on the side of the platform, the personnel land. The existing fixed platform has the following disadvantages: The marine weather environment changes rapidly, and the platform is greatly affected by surges, strong winds, etc., and safety accidents are likely to occur; there are only two landing surfaces at the low tide level and the high tide level, and it is not easy to land at other water levels. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects in the prior art, a dock for temporary docking of a marine trestle is provided.

[0005] The technical solution of the utility model is as follows: A dock for temporary docking of a marine trestle includes multiple steel pipe columns, a floating box, and a staircase assembly; a limiting cavity is formed between the multiple steel pipe columns; the floating box is placed in the limiting cavity and slides up and down along the limiting cavity, and a limiting locking mechanism is assembled at the top of the multiple steel pipe columns; the staircase assembly is arranged on one side of the steel pipe columns; Since the floating box moves up and down in the limiting cavity, it can well adapt to the changes of different water levels. Whether it is the high tide level or the low tide level, the dock can maintain a stable docking position, providing a safe docking environment for the ship; the combined structure of the floating box and the steel pipe columns is relatively simple, easy to install and disassemble, and at the same time is also convenient for daily maintenance and upkeep; the limiting locking mechanism is used to intercept the floating box after it slides to the top of the steel pipe columns, preventing the floating box in the limiting cavity from detaching from the fixation of the multiple steel pipe columns due to external forces such as sea waves, improving the safety of the dock.

[0006] Preferably, the staircase assembly includes a staircase body, a guardrail, and staircase steel pipe columns; the staircase steel pipe columns are parallel to two of the steel pipe columns on one side of the floating box, the staircase body is welded and fixed to the staircase steel pipe columns and two of the steel pipe columns on one side of the floating box, and the guardrail is assembled on both sides of the staircase body. The guardrail effectively prevents the risk of personnel falling, and the stable support of the staircase steel pipe columns ensures the stability of the staircase body when bearing loads.

[0007] Preferably, rubber shock-absorbing blocks are installed at the bottom of the floating box. When people get on and off the dock, the rubber shock-absorbing blocks can provide a certain buffering effect, reducing the safety risks caused by unsteady walking or accidental collisions.

[0008] Preferably, reinforcing ribs are installed on the sides of the floating box. This enhances the structural strength and stability of the floating box, preventing the floating box from deforming or being damaged due to uneven stress. This helps maintain the stability and integrity of the floating box and extends its service life.

[0009] Preferably, the four corners of the floating box are chamfered, and the size of the chamfer is the same as the size of the corners of the steel pipe column. The chamfer design makes the contact surface between the floating box and the steel pipe column smoother when they come into contact, reducing the local high stress caused by sharp corners. This design helps disperse the contact stress, avoiding wear and damage caused by stress concentration. The chamfer design makes it easier for the floating box to align with the steel pipe column during installation, reducing the installation difficulty and time. At the same time, it also reduces the risk of errors and damage caused by improper installation. In the marine environment, external forces such as wind and waves have a greater impact on the dock structure. The chamfer can enhance the connection strength between the floating box and the steel pipe column, improving the ability of the overall structure to resist external forces.

[0010] Preferably, a support steel pipe column is provided on the side of the floating box away from the stair assembly, and a guiding groove for sliding connection with the support steel pipe column is provided on the floating box. The support steel pipe column, as an additional support structure, can significantly increase the stability of the floating box on the side away from the stairs.

[0011] Preferably, the limit locking mechanism includes a plurality of diagonal braces and a plurality of horizontal bracings; the plurality of diagonal braces and the plurality of horizontal bracings are assembled between adjacent multiple steel pipe columns and support steel pipe columns; the diagonal braces provide additional support force for the entire structure through their inclined angles and stiffness. It can resist forces and torques from different directions, thereby enhancing the anti-overturning ability and overall stability of the structure. The horizontal bracings mainly play a role in connecting and strengthening, tightly connecting multiple steel pipe columns and support steel pipe columns in the horizontal direction to form an overall force-bearing system.

[0012] Preferably, the heights of multiple steel pipe columns and support steel pipe columns are the same. When the heights of multiple steel pipe columns and support steel pipe columns are the same, they can bear the loads from the upper structure more evenly. This uniform force-bearing helps reduce the additional stress and deformation caused by height differences, thereby enhancing the stability of the overall structure.

[0013] Preferably, the guardrail is made of steel plate and is welded to the stair body. The guardrail welded with steel plate has sufficient strength and stability to ensure that it is not easily deformed or damaged when subjected to external impacts, effectively preventing accidents.

[0014] Preferably, it further includes lighting facilities, which are assembled on the top of the staircase body and the floating boxes. It provides lighting for the operators and improves the safety of the operation.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] A dock for the temporary berthing of a marine trestle has strong flexibility and expandability. According to needs, the number and position of the floating boxes can be increased or decreased to adapt to the berthing requirements of ships of different scales; the floating boxes can move up and down along the steel pipe columns and can well adapt to the changes in different water levels; whether it is high tide or low tide, the dock can maintain a stable berthing position and provide a safe berthing environment for the ships; the floating boxes can quickly adapt to the water level changes, reduce the extension of the berthing time caused by waiting for the appropriate water level, improve the operation efficiency of the dock, and reduce the waiting cost of the ships.

[0017] Furthermore, the limit locking mechanism is installed at the top of the steel pipe column and is used to lock the floating box when it slides to the top of the steel pipe column to prevent it from disengaging from the limit cavity due to external forces such as sea waves; and, the limit locking mechanism is used to fasten multiple steel pipe columns to strengthen the stability of the limit cavity formed by the connection of multiple steel pipe columns.

[0018] Furthermore, compared with the traditional fixed dock, the cost of building and maintaining this temporary berthing dock is lower. The combined structure of the floating box and the steel pipe column is relatively simple, easy to install and disassemble, and also convenient for daily maintenance and upkeep.

[0019] Furthermore, since the floating box does not directly contact the seabed, it can reduce the damage to the seabed ecological environment and avoid the damage to the seabed organisms and terrain. In addition, the materials of the floating box and the steel pipe column can also be recycled and reused, and it has good environmental protection performance.

Specific implementation mode

[0027] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention.

[0028] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating directions or position relationships are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0029] As Figures 1 to 3 shown, a dock for temporary docking of a marine trestle includes a plurality of steel pipe columns 1, floating boxes 2 and a staircase assembly 3; the steel pipe columns 1 serve as the main support structure of the dock, having the characteristics of high strength and corrosion resistance, and can ensure the stability of the dock under different sea conditions. These steel pipe columns 1 are usually driven into the seabed to provide a solid foundation support. In this embodiment, the steel pipe piles 1 have the same specifications as the adjacent steel trestle, and the construction processes and related depths are all the same; this makes the coordination and unity of the two in terms of structural performance, safety and durability, and improves the overall quality of the device.

[0030] A limiting cavity 10 is formed between the plurality of steel pipe columns 1; the floating box 2 is placed in the limiting cavity 10 and slides up and down along the limiting cavity 10; as the water level changes, the floating box 2 slides up and down in the limiting cavity 10 along the height direction of the steel pipe column 1 to adapt to the changes in different marine environments. Whether it is high tide or low tide, the dock can maintain a stable docking position and provide a safe docking environment for ships.

[0031] Among them, rubber shock-absorbing blocks are installed at the bottom of the floating box 2. In the complex and changeable marine environment, the rubber shock-absorbing blocks can help the floating box better adapt to the water level changes and the action of wind and waves, maintain the stability of the floating box 2. Through its elastic deformation, the shock-absorbing blocks can absorb and buffer external forces, reduce the swaying and tilting of the floating box, so as to ensure the overall stability and safety of the wharf structure; when people go up and down the wharf, the shock-absorbing blocks can also provide a certain buffering effect, reducing the safety risks caused by unsteady walking or accidental collision; reinforcing ribs are installed on the side of the floating box 2, and the reinforcing ribs enhance the safety and reliability of the floating box 2. In the marine environment, the floating box needs to bear the action of various forces such as ship docking and wind and wave impact. The addition of the reinforcing ribs can effectively disperse and bear these forces, preventing the floating box from deforming or being damaged due to uneven force. This helps to maintain the stability and integrity of the floating box and extend its service life.

[0032] Furthermore, the four corners of the floating box 2 are chamfers 21, and the size of the chamfers 21 is the same as the size of the edges and corners of the steel pipe column 1; the chamfers 21 make it easier for the floating box to align with the steel pipe column 1 during the installation process, reducing the installation difficulty and time; at the same time, it also reduces the risk of errors and damage caused by improper installation. When the floating box 2 contacts the steel pipe column 1, the chamfers 21 make the contact surface smoother, reducing the local high stress generated by the sharp edges and corners; on the side of the floating box 2 away from the stairs, there is a support steel pipe column 4, and a guiding groove 22 slidably connected to the support steel pipe column 4 is provided on the floating box 2; the support steel pipe column 4, as an additional support structure, can significantly increase the stability of the floating box 2 on the side away from the stair assembly 3; the guiding groove 22 enables the floating box 2 to smoothly move up and down along the support steel pipe column 4 to adapt to the changes in different water levels.

[0033] Among them, a limit locking mechanism 5 is assembled at the top of multiple steel pipe columns 1, which is used to intercept the floating box 2 after it slides to the top of the steel pipe column 1, preventing the floating box 2 in the limit cavity 10 from detaching from the multiple steel pipe columns 1 due to external forces such as sea waves; the limit locking mechanism 5 includes multiple diagonal braces 51 and multiple horizontal braces 52. The multiple diagonal braces 51 and multiple horizontal braces 52 are assembled between adjacent multiple steel pipe columns 1 and support steel pipe columns 4. The horizontal braces 52 mainly play a role of connection and reinforcement, tightly connecting the multiple steel pipe columns 1 and support steel pipe columns 4 in the horizontal direction to form an overall stress system; through its inclined angle and stiffness, the diagonal braces 51 provide additional support force for the entire structure, and can resist forces and torques from different directions, thereby enhancing the anti-overturning ability and overall stability of the structure; the multiple steel pipe columns 1 and support steel pipe columns 4 have the same height, which can more evenly bear the load from the upper structure. This uniform stress helps to reduce the additional stress and deformation caused by height differences, thereby enhancing the stability of the overall structure.

[0034] The stair assembly 3 is arranged on the side of the steel pipe column 1, providing convenience for personnel to go up and down the wharf. The stair assembly 3 includes a stair body 31, a guardrail 32, and a stair steel pipe column 33; the stair steel pipe column 33 is parallel to the two steel pipe columns 1 on one side of the floating box 2, the stair body 31 is welded and fixed to the stair steel pipe column 33 and the two steel pipe columns 1 on one side of the floating box 2, and the guardrail 32 is assembled on both sides of the stair body 31; the design of the stair assembly 3 fully considers the safety requirements of personnel going up and down the wharf. The guardrail 32 effectively prevents the risk of personnel falling, while the stable support of the stair steel pipe column 33 ensures the stability of the stair body 31 when bearing loads, improving the safety of wharf use.

[0035] Among them, the guardrail 32 is a steel plate, which is welded to the stair body 31. The steel plate ensures that the guardrail can withstand large external forces and impacts, thereby protecting users from accidental injuries.

[0036] A wharf for temporary docking of a marine trestle also includes lighting facilities, which are assembled on the top of the stair body 31 and the floating box 2, improving the safety of night use and helping users to clearly see the steps and handrails of the stairs even at night or in low-light conditions, avoiding the risk of stepping empty or falling.

[0037] As described above, the above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
