Description

Technical Field

[0001] This utility model belongs to the field of container insulation technology, and in particular relates to a rapid fixing structure for the internal insulation layer of an offshore platform container. Background Technology

[0002] In offshore platform operations, containers serve as critical storage and work spaces, and their internal insulation performance is crucial to the quality of stored materials and the working environment for personnel. However, traditional methods of fixing the internal insulation layer of containers have many problems.

[0003] Traditional fixed structures are complex, with cumbersome installation processes. Construction within the limited space of an offshore platform is difficult and inefficient, significantly increasing labor and time costs. Furthermore, the humid and saline marine environment makes traditional structures susceptible to corrosion, leading to loosening and detachment of the insulation layer, loss of insulation performance, frequent and costly maintenance.

[0004] Furthermore, traditional structures lack flexibility and are difficult to adapt to containers of different sizes or insulation materials of different specifications. When the container's function is adjusted, redesign and installation are required, resulting in wasted resources. Moreover, the supporting structure of adjacent insulation layers lacks a reliable adjustment and fixing mechanism, making it prone to displacement due to platform swaying, and even damaging the integrity of the insulation material, further weakening the insulation effect.

[0005] Therefore, there is an urgent need for a rapid fixing structure for the insulation layer that is efficient, reliable, and highly adaptable. Thus, we need to design a rapid fixing structure for the internal insulation layer of offshore platform containers to solve these problems. Utility Model Content

[0006] The problem this invention aims to solve is to provide a rapid fixing structure for the internal insulation layer of a marine platform container.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A rapid fixing structure for the internal insulation layer of an offshore platform container includes a base on which a container body is mounted. The container body contains an insulated top plate, an insulated floor, and insulated side plates. A support mechanism is provided between two adjacent insulated side plates. The support mechanism includes a support tube and a support rod. Each end of the support rod and the support tube has a support base. The other end of the support tube has a fixed clamping seat. A semi-gear is rotatably mounted on the clamping seat. A rack is fixed to the side wall of the support rod. The other end of the support rod is inserted into the support tube from the end with the clamping seat. When the teeth on the semi-gear mesh with the rack, the support rod and the support tube are relatively fixed. When the teeth on the semi-gear disengage from the rack, the support rod and the fixed tube slide relative to each other.

[0009] Preferably, a limiting strip is fixedly provided inside the support tube, the extension direction of the limiting strip is in the same direction and parallel to the axis of the support tube, and a limiting groove is formed on the side wall of the support rod, the extension direction of the limiting groove is in the same direction and parallel to the axis of the support rod, when the support rod is inserted into the support tube, the limiting strip is located in the limiting groove and slides against the inner wall of the limiting groove.

[0010] This design, using the combination of limiting strips and limiting grooves, guides the sliding of the support rod within the support tube, ensuring that the support rod can only move along the axial direction of the support tube. This prevents the support rod from rotating or deviating during sliding, ensuring that the half-tooth gear and rack can always mesh precisely. This improves the stability and reliability of the support mechanism during adjustment, while also reducing wear between components and extending the service life of the structure.

[0011] Preferably, an installation groove is provided on the side wall of the top clamping seat, and an anti-disengagement groove communicating with the outside is provided on the side wall of the installation groove. A limit hook and a spring are provided in the installation groove. The limit hook is in the shape of a "7" and its bottom end is hinged to the inner wall of the installation groove. One end of the spring is connected to the limit hook and the other end is connected to the inner wall of the installation groove. When the spring is in its natural state, the upper end of the limit hook will extend out of the installation groove from the anti-disengagement groove. A handle is also fixedly provided on the half gear, and a limit post is fixedly provided on the handle. When the teeth on the half gear mesh with the rack, the limit hook will hook the limit post.

[0012] This design, with its limit hook, spring, and limit post, ensures that after the half-gear and rack are engaged and fixed, the limit hook can engage with the limit post, preventing the half-gear from accidentally rotating due to vibration or other external forces and causing loosening of the engagement. This further enhances the stability of the support mechanism. The spring's natural state ensures that the limit hook always tends to extend out of the anti-disengagement groove, guaranteeing reliable positioning without external force intervention. The handle facilitates the rotation adjustment of the half-gear, and the overall structure balances stable fixation with ease of operation.

[0013] Preferably, a through groove is also provided on the side wall of the mounting groove, and a lever is fixedly provided on the limiting hook, with the free end of the lever passing through the through groove and located outside the mounting groove.

[0014] This design allows the operator to easily control the rotation of the limit hook by extending the lever from the outside of the mounting slot. This separation of the limit hook from the limit post releases the restriction on the limit post, facilitating adjustment of the half-gear's position. The through slot provides the lever with movement space, making the operation of the limit hook more flexible and effortless, further optimizing the adjustment process of the support mechanism and improving operational efficiency.

[0015] Preferably, a connecting pipe is also fixedly installed on the support, and a fixing bolt is installed through the side wall of the connecting pipe. Fixing holes are provided radially on both the support pipe and the support rod. When the end of the support pipe or the support rod is inserted into the connecting pipe, the fixing hole will be aligned with the fixing bolt. After rotating the fixing bolt, the end of the fixing bolt will be inserted into the fixing hole.

[0016] This design, with the connection of the connecting pipe, fixing bolts, and fixing holes, enables a detachable connection between the bracket and the support pipe / rod. This facilitates the individual production, transportation, and replacement of each component. When a component is damaged, there is no need to replace the entire support mechanism, reducing maintenance costs. Simultaneously, the fixing bolts inserted into the fixing holes provide a secure and reliable fixation, ensuring a tight connection between the bracket and the support pipe / rod, preventing loosening during use.

[0017] Preferably, two sets of connecting blocks are respectively provided on the supports on both sides of the connecting pipe, each set of connecting blocks consists of two blocks, the two connecting blocks are connected by a rotating shaft, and a baffle and a limiting plate are fixedly provided on the rotating shaft between the two connecting blocks, the baffle and the limiting plate are perpendicular to each other.

[0018] This configuration, using connecting blocks, a rotating shaft, baffles, and limiting plates, provides auxiliary fixation for the insulation side panels. The baffles abut against the insulation side panels from the side, preventing lateral movement, while the limiting plates restrict longitudinal displacement. The two components, perpendicular to each other, form a three-dimensional restraint, enhancing the stability of the insulation side panels. The rotating shaft design allows the baffles and limiting plates to be flexibly adjusted according to the thickness of the insulation side panels, accommodating different insulation layer specifications and improving the structure's versatility.

[0019] Preferably, the cross-section of the support is "L" shaped, and the fixed connecting pipe is fixed on the long side.

[0020] With this design, the support has an "L"-shaped cross-section, and the connecting pipe is fixed on the long side. This allows the support to contact the insulation side panel more stably, and the long side provides a larger support area, enhancing the support for the insulation top panel and preventing deformation of the support due to concentrated stress. At the same time, the "L"-shaped design also facilitates the installation of the support with other components, resulting in a simple structure and strong practicality.

[0021] Preferably, the length of the limiting plate does not exceed the length of the baffle, and the length of the baffle is not less than the length of the rotating shaft.

[0022] This design allows the limiting plate to provide stable support for the baffle after the rotating shaft is turned, ensuring that the baffle always has a good clamping effect on the insulation side plate and guaranteeing the stability of the clamping. At the same time, the limiting plate will not affect the surrounding environment due to its excessive length, thus optimizing the fixing effect on the insulation side plate.

[0023] Preferably, the through groove is an arc-shaped groove, and its center overlaps with the hinge point of the limiting hook and the side wall of the mounting groove.

[0024] With this design, the through groove is arc-shaped and its center overlaps with the hinge point of the limit hook. This allows the lever to move smoothly along the arc-shaped through groove when it drives the limit hook to rotate, avoiding any jamming. This ensures that the rotation of the limit hook is more stable and flexible, improving the smoothness of operation and making the separation and hooking process between the limit hook and the limit post more convenient and efficient.

[0025] The advantages and positive effects of this utility model are:

[0026] This invention achieves rapid adjustment and fixation of the support mechanism length through the nested cooperation of the support tube and support rod, combined with the meshing and disengagement design of the semi-gear and rack. When the semi-gear and rack are engaged, the relative position of the support rod and support tube is stably fixed, ensuring support strength; when disengaged, the length can be flexibly adjusted to adapt to different spacings. The operation is convenient, allowing for rapid fixation, improving installation efficiency, and meeting the needs of rapid installation of internal insulation layers for offshore platform containers.

Detailed Implementation

[0039] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] Example: Figure 1 As shown, a quick-fixing structure for the internal insulation layer of an offshore platform container includes a base 1, a container 2 on the base 1, an insulation top plate 3, an insulation floor and insulation side plates 4 respectively installed inside the container 2, and a support mechanism 6 between two adjacent insulation side plates 4.

[0043] The support mechanism 6 includes a support tube 601 and a support rod 602. One end of both the support rod 602 and the support tube 601 is provided with a support seat 618. The other end of the support tube 601 is fixedly provided with a clamping seat 604. A half-tooth gear 605 is rotatably provided on the clamping seat 604. A rack 603 is fixedly provided on the side wall of the support rod 602. The other end of the support rod 602 is inserted into the support tube 601 from the end where the clamping seat 604 is installed. When the teeth on the half-tooth gear 605 mesh with the rack 603, the support rod 602 is relatively fixed to the support tube 601. When the teeth on the half-tooth gear 605 separate from the rack 603, the support rod 602 slides relative to the fixed tube.

[0044] The nested design of the support tube 601 and the support rod 602 provides a basis for adjusting the length of the support mechanism 6. The relative state of the support rod 602 and the support tube 601 is determined by the meshing state of the half-tooth gear 605 and the rack 603. When they are meshed, they are fixed, while when they are separated, they can slide. This allows for controllable adjustment of the support length, thus adapting to the fixing of insulation side plates 4 with different spacing.

[0045] A limiting strip 615 is fixedly installed inside the support tube 601. The extension direction of the limiting strip 615 is in the same direction and parallel to the axis of the support tube 601. A limiting groove 616 is opened on the side wall of the support rod 602. The extension direction of the limiting groove 616 is in the same direction and parallel to the axis of the support rod 602. When the support rod 602 is inserted into the support tube 601, the limiting strip 615 is located in the limiting groove 616 and slides against the inner wall of the limiting groove 616.

[0046] The extension directions of both the limiting strip 615 and the limiting groove 616 are parallel to the axis of the corresponding pipe fitting. They slide in close contact with each other, constraining the movement trajectory of the support rod 602 within the support tube 601. Simultaneously, they can also be linked with the nested structure of the support rod 602 and the support tube 601 to ensure that the support rod 602 can only slide axially, guaranteeing the precise meshing of the half-tooth gear 605 and the rack 603.

[0047] An installation groove 608 is provided on the side wall of the top seat 604. An anti-disengagement groove 611 communicating with the outside is provided on the side wall of the installation groove 608. A limit hook 609 and a spring 610 are provided in the installation groove 608. The limit hook 609 is "7" shaped and its bottom end is hinged to the inner wall of the installation groove 608. One end of the spring 610 is connected to the limit hook 609 and the other end is connected to the inner wall of the installation groove 608. When the spring 610 is in its natural state, the upper end of the limit hook 609 will extend out of the installation groove 608 from the anti-disengagement groove 611. A handle 606 is also fixedly provided on the half gear 605. A limit post 607 is fixedly provided on the handle 606. When the teeth on the half gear 605 mesh with the rack 603, the limit hook 609 will hook the limit post 607.

[0048] The mounting slot 608 provides mounting space for the limit hook 609 and the spring 610, while the anti-disengagement slot 611 provides a channel for the extension of the limit hook 609. The elastic force of the spring 610 keeps the limit hook 609 in the extended state in its natural state, cooperating with the meshing state of the half gear 605 and the rack 603; when the half gear 605 meshes with the rack 603, the limit hook 609 hooks precisely onto the limit post 607 of the handle 606, maintaining the meshed and fixed state by restricting the rotation of the half gear 605.

[0049] A through groove 621 is also provided on the side wall of the mounting groove 608. A toggle block 617 is fixedly provided on the limiting hook 609, and the free end of the toggle block 617 passes through the through groove 621 and is located outside the mounting groove 608.

[0050] The engagement of the lever 617 and the through slot 621 enables control of the limiting hook 609 outside the mounting slot 608. The displacement of the lever 617 is transmitted to the limiting hook 609 through the through slot 621, causing the limiting hook 609 to rotate around the hinge point. This changes the engagement state between the limiting hook 609 and the limiting post 607, allowing the half-gear 605 to separate from the rack 603. In other words, when the lever 617 is moved, the limiting hook 609 rotates, releasing the constraint of the limiting hook 609 on the limiting post 607, allowing the half-gear 605 to rotate to the state of separation from the rack 603.

[0051] A connecting pipe 620 is also fixedly installed on the support 618. A fixing bolt 623 is installed through the side wall of the connecting pipe 620. Fixing holes 622 are provided radially on both the support pipe 601 and the support rod 602. When the end of the support pipe 601 or the support rod 602 is inserted into the connecting pipe 620, the fixing hole 622 will be aligned with the fixing bolt 623. After rotating the fixing bolt 623, the end of the fixing bolt 623 will be inserted into the fixing hole 622.

[0052] The connecting pipe 620 serves as the connection medium between the bracket 618 and the support pipe 601 and support rod 602. Its cooperation with the fixing bolt 623 and fixing hole 622 forms a detachable connection structure, facilitating maintenance and replacement. After the support pipe 601 or support rod 602 is inserted into the connecting pipe 620, the alignment of the fixing hole 622 and the fixing bolt 623 ensures that rotating the bolt will fix both. This allows the bracket 618 to be separated from the main body of the support mechanism 6, and is linked to the overall adjustment function of the support mechanism 6, facilitating component replacement and adaptation to different brackets 618.

[0053] Two sets of connecting blocks 612 are respectively provided on the brackets 618 on both sides of the connecting pipe 620. Each set of connecting blocks 612 consists of two blocks. The two connecting blocks 612 are connected by a rotating shaft 619. A baffle 613 and a limiting plate 614 are fixedly provided on the rotating shaft 619 between the two connecting blocks 612. The baffle 613 and the limiting plate 614 are perpendicular to each other.

[0054] The connecting block 612 forms a rotation fulcrum through the rotating shaft 619. The baffle 613 and the limiting plate 614 are fixed to the rotating shaft 619 and are perpendicular to each other. Their movements are synchronized with the rotation of the rotating shaft 619. This structure is linked to the supporting function of the support 618: the baffle 613 can abut against the insulation side plate 4, and the limiting plate 614 provides support for the baffle 613 through its connection with the support 618, together forming a constraint on the insulation side plate 4.

[0055] The support 618 has an "L" shaped cross section, and the fixed connecting pipe 620 is fixed on the long side.

[0056] The “L” shaped cross section gives the support 618 two mutually perpendicular force-bearing surfaces. The long side provides a fixed foundation for the connecting pipe 620. This structure is linked with the installation position of the connecting pipe 620 to ensure that the force transmitted by the support mechanism 6 through the support 618 can be evenly distributed on the contact surface between the support 618 and the insulation layer.

[0057] The length of the limiting plate 614 does not exceed that of the baffle 613, which can prevent it from extending too far and affecting the movement of the baffle 613; the length of the baffle 613 is not less than the length of the rotating shaft 619, ensuring that the contact area of ​​the baffle 613 with the heat insulation side plate 4 matches the abutment function of the baffle 613.

[0058] The through groove 621 is an arc-shaped groove, and its center overlaps with the hinge point of the side wall of the limit hook 609 and the mounting groove 608.

[0059] The center of the arc-shaped through groove 621 coincides with the hinge point of the limit hook 609. This design is linked to the rotation trajectory of the limit hook 609, ensuring that the toggle block 617 moves smoothly along the through groove 621 when the limit hook 609 rotates, avoiding motion interference and ensuring stable switching of the engagement state between the limit hook 609 and the limit post 607.

[0060] The working process of this embodiment is as follows: When it is necessary to disassemble the insulation layer inside the box 2, the bracket 618 is first installed on the support rod 602 and the support tube 601 respectively. The end of the support rod 602 or the support tube 601 is inserted into the connecting tube 620. After the fixing hole 622 is aligned with the fixing bolt 623, the fixing bolt 623 is screwed into the fixing hole 622 to complete the connection between the bracket 618 and the support tube 601 or the support rod 602.

[0061] Furthermore, for ease of operation, the support rod 602 is positioned at the top during support. The insulation top plate 3 is then placed on the support bracket 618 at the end of the support rod 602, and the insulation bottom plate 5 is placed below the support bracket 618 at the end of the support tube 601. After adjusting the height, the half-gear 605 is rotated via the handle 606, causing the teeth on the half-gear 605 to mesh with the rack 603, thus providing support for the insulation top plate 3 and the insulation bottom plate 5. During the rotation of the handle 606, the half-gear 605 will also continue to support the insulation top plate 3 and the insulation bottom plate 5 through its engagement with the rack 603. The support rod 602 is pushed out to further ensure the stability of the support. When the handle 606 is rotated to contact the limit hook 609, the continuous movement of the handle 606 will push the limit hook 609 extending from the anti-disengagement groove 611 into the mounting groove 608 and compress the spring 610. When the limit post 607 passes the limit hook 609, the spring 610 will extend and reset, pushing the limit hook 609 to extend out from the anti-disengagement groove 611 again, hooking the limit post 607 and limiting the limit post 607 to prevent the support from loosening.

[0062] Then install the insulation side plate 4. Before installing the insulation side plate 4, the rotating shaft 619 needs to be rotated to separate the baffle 613 from the support 618, and make the limiting plate 614 fit with the support 618. Then insert the insulation side plate 4 behind the baffle 613 to constrain the insulation side plate 4.

[0063] When it is necessary to disassemble the insulation layer inside the box 2, first remove the insulation side plate 4, then push the lever 617 to move along the through groove 621. The movement of the lever 617 will drive the limit hook 609 to move, so that the limit hook 609 enters the installation groove 608 through the part protruding from the anti-detachment groove 611, so that the constraint of the limit post 607 is removed. Then, rotate the half gear 605 in the opposite direction by the handle 606 to separate the fish-eating rack 603 on the half gear 605. Then, insert the support rod 602 back into the support tube 601, and then remove the insulation top plate 3 and the insulation bottom plate 5.

[0064] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
