Description

Technical Field

[0001] This invention relates to the field of marine self-elevating platform technology, and in particular to a fixed pile chamber for a cross-shaped lifting system of a self-elevating platform. Background Technology

[0002] As a crucial piece of equipment in the field of marine engineering, self-elevating platforms traditionally employ an open piling structure for their rack and pinion lifting systems. While this offers the advantage of convenient equipment assembly and disassembly, the exposed mechanical components are difficult to maintain effectively in harsh sea conditions. With the increasing demands for deeper-water and larger-scale operations such as offshore wind power installations, the need for multi-functional platform deck layouts has led to the development of integrated piling chambers as a solution. These enclosed spaces not only enhance the protection level of the lifting device but can also be expanded into multi-functional compartments through integrated architectural design.

[0003] The existing design of the pile-fixing chamber has significant defects: the lifting port of the top equipment relies on the opening and closing of the weatherproof cover, and the cover needs to be closed in rainy or snowy weather to prevent internal operations from being affected; however, the ventilation and heat dissipation performance is insufficient in the sealed state, and the temperature inside the chamber rises sharply, forming a high-temperature and high-pressure environment, which seriously affects the maintenance personnel's ability to work continuously and the stability of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a fixed pile chamber for a self-elevating platform cross-shaped lifting system, which eliminates the need for frequent opening and closing of the hatch, thus preventing rain and snow from entering and effectively reducing the temperature and air pressure inside the fixed pile chamber through air convection, significantly improving the working environment for maintenance personnel.

[0005] To achieve the above objectives, the present invention provides a fixed pile chamber for a self-elevating platform cross-shaped lifting system, comprising:

[0006] A wall, the interior of which forms a fixed workspace;

[0007] A top plate is provided on the top of the enclosure and connected to the enclosure. The top plate has ventilation and hoisting holes, and ventilation covers are provided at the ventilation and hoisting holes.

[0008] A box-type fixed pile structure, wherein the box-type fixed pile structure is fixedly connected to the top inner side of the enclosure wall;

[0009] The pile leg is disposed within the working space and connected to the center of the box-type fixed pile structure;

[0010] The ventilation hoisting hole is used for hoisting the pile fixing chamber during installation and for ventilation inside the hoisting chamber when the self-elevating platform is working.

[0011] Compared with existing technologies, the fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention has the following advantages: It is used for hoisting the fixed pile chamber during installation and for ventilation within the hoisting chamber during platform operation. A ventilation cover is installed on the ventilation hoisting hole, allowing the hole to both protect against rain and snow and provide ventilation. This application, through the cooperation of the ventilation hoisting hole and the ventilation cover, enables the ventilation hoisting hole to serve both equipment hoisting and natural ventilation functions. During operation, there is no need to frequently open and close the cover, preventing rain and snow intrusion and effectively reducing the temperature and air pressure inside the fixed pile chamber through air convection, significantly improving the working environment for maintenance personnel.

[0012] The fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention includes a ventilation cover with a base, the size of which matches the size of the ventilation hoisting hole.

[0013] The fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention includes a ventilation cover that further includes a side plate disposed on the base. The base and the side plate have ventilation space inside, and the side plate is provided with louvers.

[0014] In the fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention embodiment, multiple louvers are provided, and the multiple louvers are evenly distributed on the side plates around the ventilation cover.

[0015] In the fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention, the top of the side plate is provided with a lifting lug, and the base is provided with a screw hole.

[0016] In the fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention, the top plate is provided with a plurality of ventilation and hoisting holes, which are evenly distributed at the four corners of the top plate.

[0017] The self-elevating platform cross-shaped lifting system of this invention has a fixed pile chamber in which the box-type fixed pile structure is configured as a cross shape and both ends of the cross shape are connected to the vertical centerline of the enclosure wall.

[0018] In the fixed pile chamber of the self-elevating platform cross-shaped lifting system of this invention, the pile legs are connected to a lifting foundation around them, and the lifting foundation and the pile legs are connected by a rack and pinion.

[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] like Figure 1-4As shown, a preferred embodiment of the present invention discloses a fixed-pile chamber for a self-elevating platform cross-shaped lifting system, comprising: a wall 1 and a top plate 2. The wall 1 and top plate 2 form a working space for the fixed-pile chamber. The enclosed working space formed by the wall 1 and top plate 2 isolates the system from harsh external environments (such as wind, rain, and salt spray), ensuring continuous and stable operation of the lifting device under various sea conditions. This solves the problem of traditional open-type fixed-pile frames being unable to be maintained in severe weather. The top plate 2 is located on top of and connected to the wall 1, and has openings on it. The ventilation hoisting hole 21 is equipped with a ventilation cover 3. The ventilation cover 3 serves both as a hoisting device and a natural ventilation device. Under normal circumstances, the ventilation cover 3 can ensure ventilation while providing shelter from wind and rain, so that the cover does not need to be opened and closed frequently during the pile fixing chamber operation. This not only prevents rain and snow from entering, but also effectively reduces the temperature and air pressure inside the pile fixing chamber through air convection, significantly improving the working environment for maintenance personnel. On the other hand, the ventilation hoisting hole 21 can be converted into a permanent ventilation channel when not in hoisting conditions, reducing the need for additional openings, simplifying the structure and ensuring the overall airtightness of the chamber.

[0030] The piling chamber is also equipped with a box-type piling structure 4 and pile legs 5. The box-type piling structure 4 is fixedly connected to the top of the inner side of the enclosure 1. The box-type piling structure 4 is rigidly connected to the top of the enclosure 1 to form a high-rigidity support system, which improves the load transfer efficiency of the cross-shaped pile legs 5 and enhances the platform's resistance to storm loads. The pile legs 5 are set in the working space and connected to the center of the box-type piling structure 4. The pile legs 5 are positioned by the center of the box structure to ensure the precise meshing of the lifting rack and the drive gear, reduce operating vibration and wear failure rate, and extend the equipment life.

[0031] In this embodiment of the invention, during hoisting, the hoisting hook lifts the fixed pile chamber through the ventilation cover 3. When the self-elevating platform is in operation, ventilation is provided through the ventilation cover 3 within the ventilation hoisting hole 21 for air circulation within the hoisting chamber. The ventilation cover 3 is positioned on the ventilation hoisting hole 21, allowing it to both protect against rain and snow and provide ventilation. This application, through the cooperation of the ventilation hoisting hole 21 and the ventilation cover 3, enables the ventilation hoisting hole 21 to serve both equipment hoisting and natural ventilation functions. During operation, there is no need to frequently open and close the cover, preventing rain and snow intrusion and effectively reducing the temperature and air pressure within the fixed pile chamber through air convection, significantly improving the working environment for maintenance personnel.

[0032] In some embodiments of the present invention, the ventilation cover 3 includes a base 31, the size of which matches the size of the ventilation hoisting hole 21. The matching size design allows the ventilation cover 3 to be quickly positioned and installed. The precise matching between the base 31 and the ventilation hoisting hole 21 forms a mechanical sealing interface, which can effectively block rainwater infiltration and salt spray corrosion when closed. Compared with traditional hatch covers, this reduces the risk of leakage and solves the problem of sealing failure caused by frequent opening and closing of traditional hatch covers.

[0033] In some embodiments of the present invention, the ventilation cover 3 further includes a side plate 32 disposed on the base 31. The base 31 and the side plate 32 have ventilation spaces inside. The side plate 32 is provided with louvers 33. The louvers 33, together with the internal ventilation space, form a guiding channel. Even when the opening is closed by the base 31, sufficient ventilation cross-sectional area can still be maintained, thereby reducing heat accumulation and completely solving the "high-temperature stuffy can" effect of traditional sealed pile chambers. Specifically, the inclined blade design of the louvers 33 is designed to reduce the amount of rainwater intrusion while ensuring air exchange efficiency, achieving compatibility between waterproofing, snowproofing, and ventilation requirements.

[0034] In some embodiments of the present invention, multiple louvers 33 are provided, and the multiple louvers 33 are evenly distributed on the side plates 32 around the ventilation cover 3. The even distribution of multiple louvers 33 forms a circulation channel, which improves the air exchange efficiency of the pile chamber and avoids the problem of uneven heat dissipation caused by local airflow dead zones. On the other hand, the coordinated adjustment of multiple louvers 33 can cope with different external wind direction conditions, solving the defect that single-sided louvers 33 are easily restricted by wind direction.

[0035] In some embodiments of the present invention, the top of the side plate 32 is provided with lifting lugs 34, and multiple lifting lugs 34 are symmetrically arranged for hoisting the pile chamber. The base 31 is provided with screw holes 35, and the base 31 is fixed to the top plate 2 by bolts, which facilitates maintenance and disassembly.

[0036] In some embodiments of the present invention, the top plate 2 is provided with a plurality of ventilation hoisting holes 21, which are evenly distributed at the four corners of the top plate 2. The symmetrically arranged ventilation hoisting holes 21 at the four corners form a diagonal airflow channel, which works in conjunction with the louvers 33 of the side plate 32 to generate a three-dimensional convection effect, and the ventilation efficiency is greatly improved compared with the single hole design.

[0037] In some embodiments of the present invention, the box-type pile fixing structure 4 is configured in a cross shape, with both ends of the cross connected to the vertical centerline of the enclosure 1, so that the box-type pile fixing structures 4 are symmetrically distributed and provide the same support force to all four sides of the enclosure 1, making the overall structure of the box-type pile fixing structure 4 and the pile fixing chamber stable. The box-type pile fixing structure 4 adopts a double-layer structure design, and its structural strength is greater than that of traditional pile fixing chambers.

[0038] In some embodiments of the present invention, the pile leg 5 is connected to a lifting base 51 around its perimeter, the lifting base 51 is connected to the pile leg 5 via a rack 52, and the lifting base 51 moves along the extension direction of the rack 52.

[0039] The working process of this invention is as follows: During the hoisting of the pile fixing chamber in this embodiment, the hoisting hook lifts the pile fixing chamber through the ventilation cover 3. When the self-elevating platform is working, ventilation is provided in the ventilation hoisting hole 21 through the ventilation cover 3 for air circulation within the hoisting chamber. The ventilation cover 3 is used for hoisting the pile fixing chamber during installation and for ventilation within the hoisting chamber when the self-elevating platform is working. The ventilation cover 3 is located on the ventilation hoisting hole 21, allowing the ventilation hoisting hole 21 to both protect against rain and snow and provide ventilation.

[0040] In summary, the present invention provides a fixed pile chamber for a self-elevating platform cross-shaped lifting system. Through the cooperation of the ventilation hoisting hole 21 and the ventilation cover 3, the ventilation hoisting hole 21 can serve both equipment hoisting and natural ventilation functions. During operation, there is no need to frequently open and close the cover, which not only prevents rain and snow from entering, but also effectively reduces the temperature and air pressure inside the fixed pile chamber through air convection, significantly improving the working environment for maintenance personnel.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
