Description

Technical Field

[0001] This utility model relates to the field of waterborne construction platform technology, and in particular to a floating crane platform for waterborne construction. Background Technology

[0002] Currently, the industry's floating crane equipment for small and medium-sized water areas is the simple assembly type of floating crane, which forms an operating platform by splicing steel pipes and floating body modules. During operation, the floating body modules are first fixed in a preset position on the water surface, and then the load-bearing frame and lifting mechanism are built, relying on the fixed floating body to provide buoyancy support.

[0003] In use, the floating module and the load-bearing frame of the equipment are fixedly connected. The support width cannot be adjusted after assembly. When facing narrow waterways, it is easy to have difficulty passing through due to its large size. When facing heavy-load operations, the insufficient support spacing results in a low center of gravity height, which limits its adaptability.

[0004] Therefore, this utility model provides a floating platform for waterborne construction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a floating platform for waterborne construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a floating platform for waterborne construction, comprising a chassis, a width adjustment mechanism provided on the chassis, the width adjustment mechanism comprising a support base plate fixedly connected to the chassis, a rotating hinge plate rotatably connected to the top of the support base plate, a linkage rod rotatably connected to the outer side of the rotating hinge plate, a fixed mounting plate rotatably connected to the end of the linkage rod away from the rotating hinge plate, and a cylinder mounted on the outer side of the top of the chassis, the driving end of the cylinder being fixedly connected to the fixed mounting plate.

[0007] In a preferred embodiment, a limiting guide component is also included, which includes a guide rail fixedly connected to the chassis, and a sliding block is slidably connected to the outer side of the guide rail.

[0008] In a preferred embodiment, the top end of the sliding block is fixedly connected to the fixed mounting plate.

[0009] In a preferred embodiment, a float module is fixedly connected to the outer side of the fixed mounting plate, and the float module moves synchronously with the width adjustment mechanism along with the fixed mounting plate.

[0010] In a preferred embodiment, a limiting slide bar is fixedly connected to the top of the float module, and the limiting slide bar is vertically fixed to the float module.

[0011] In a preferred embodiment, a support platform is fixedly connected to the top of the chassis.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention uses a cylinder to drive the extension and retraction of a fixed mounting plate to move horizontally, which in turn drives the linkage and sliding block to move synchronously. This causes the rotating hinge plate to rotate around the support base plate, converting the linear driving force into the horizontal displacement of the floating module. This, in turn, causes the limiting slide rod to slide relative to the bearing platform, constraining the movement trajectory. This achieves stepless dynamic adjustment of the platform support width. This design enables real-time adjustment of buoyancy distribution, increases the center of gravity height, and enhances the anti-overturning moment during hoisting operations based on the load size and water conditions. It also has the advantages of compact structure, fast response, and accurate positioning. It solves the problem of limited adaptability of traditional assembled floating cranes, allowing the platform to shrink its width to meet navigation requirements during deployment and expand its width during operation to increase safety margin, significantly enhancing the environmental adaptability of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a floating platform for water construction, including a chassis 1 and a width adjustment mechanism 2. The width adjustment mechanism 2 includes a support base plate 21 fixedly connected to the chassis 1. A rotating hinge plate 22 is rotatably connected to the top of the support base plate 21. A linkage rod 23 is rotatably connected to the outer side of the rotating hinge plate 22. A fixed mounting plate 24 is rotatably connected to the end of the linkage rod 23 away from the rotating hinge plate 22. A cylinder 25 is installed on the outer side of the top of the chassis 1. The driving end of the cylinder 25 is fixedly connected to the fixed mounting plate 24.

[0025] The chassis 1 serves as the core load-bearing foundation and installation reference for the floating crane platform, providing a rigid support surface for all functional structures such as the width adjustment mechanism 2, the limit guide assembly 3, and the load-bearing platform 6. It also bears the vertical loads, horizontal impact forces, and moments generated during hoisting operations. The support base plate 21 is fixed to the top of the chassis 1, serving as the rotational support fulcrum for the rotating hinge plate 22. It transmits the force from the width adjustment mechanism 2 to the chassis 1 body, restricting the vertical displacement of the hinge plate. The rotating hinge plate 22 rotates around the support base plate 21, converting the linear driving force of the cylinder 25 into a linkage. The planar motion of 23 realizes the conversion and transmission of force direction. The linkage 23 connects the rotating hinge plate 22 and the fixed mounting plate 24 to form a multi-link linkage mechanism, which converts the rotational motion of the hinge plate into the horizontal linear motion of the fixed mounting plate 24. The fixed mounting plate 24 serves as the mounting carrier of the floating module 4, and at the same time connects the linkage 23 and the drive end of the cylinder 25, undertaking the dual functions of force transmission intermediary and load bearing. The cylinder 25 provides the power source for width adjustment, and drives the fixed mounting plate 24 to move in the horizontal direction through the extension and retraction of the piston rod, controlling the adjustment speed and stroke.

[0026] like Figure 1 and Figure 4 As shown, the limiting guide assembly 3 includes a guide slide rail 31 fixedly connected to the chassis 1, a sliding block 32 slidably connected to the outer side of the guide slide rail 31, and the top end of the sliding block 32 fixedly connected to the fixed mounting plate 24.

[0027] A floating module 4 is fixedly connected to the outside of the fixed mounting plate 24, a limit slide bar 5 is fixedly connected to the top of the floating module 4, and a bearing platform 6 is fixedly connected to the top of the chassis 1.

[0028] The guide rail 31 is fixed to the surface of the chassis 1, limiting the movement trajectory of the sliding block 32 to a straight line, and bearing the lateral load transmitted by the sliding block 32 to prevent it from deviating from the preset path. The top of the sliding block 32 is connected to the fixed mounting plate 24, and the bottom is embedded in the guide rail 31 to slide, providing guidance and constraint for the horizontal movement of the fixed mounting plate 24. The floating module 4 is fixed to the outside of the fixed mounting plate 24, and balances the platform gravity and the hoisting load through its own buoyancy. Its horizontal position changes synchronously with the width adjustment mechanism 2 to adjust the buoyancy distribution of the platform. The limiting slide bar 5 is vertically fixed to the top of the floating module 4, and can form a sliding limiting cooperation with the bearing platform 6 or other auxiliary structures to limit the vertical swaying and horizontal torsion of the floating module 4.

[0029] Working principle:

[0030] like Figure 1 - Figure 4 As shown:

[0031] In use: First, the drive end of cylinder 25 extends and retracts, which in turn moves the fixed mounting plate 24 horizontally. This causes the linkage rod 23 to move in a plane, thereby causing the rotating hinge plate 22 to rotate around the support base plate 21, realizing the conversion of the driving force direction and the transmission of motion. At the same time, the horizontal displacement of the fixed mounting plate 24 causes the sliding block 32 to slide linearly within the guide rail 31, which in turn causes the floating module 4 to change its horizontal position synchronously. This causes the limiting slide rod 5 to move relative to the bearing platform 6, realizing the dynamic adjustment of the platform support width, the optimization of buoyancy distribution, and the enhancement of lateral stability, significantly improving the adaptability and safety of water construction.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
