Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transportation equipment technology, and specifically relates to a support device for facilitating the transportation of thin-walled floating docks. Background Technology
[0002] Thin-walled floating docks, also known as concrete floating docks, concrete wharves, or concrete floating bridges, are precast from reinforced concrete in one piece, with a core filled with high-density polystyrene foam. They have advantages such as high structural strength, durability, and strong stability, and can withstand harsh weather such as cold and freezing. However, due to the concrete casting process used in thin-walled floating docks, there may be a small number of cracks inside.
[0003] Currently, thin-walled floating docks are transported by placing them directly on the chassis of trailers. During transportation, the vibrations generated by the trailers are transmitted directly to the thin-walled floating docks through the chassis, causing localized stress on the thin-walled floating docks and leading to the expansion of internal cracks, which affects the durability of the thin-walled floating docks. Utility Model Content
[0004] This utility model provides a support device for facilitating the transportation of thin-walled floating docks, in order to solve the technical problem in the prior art where the vibration generated by the trailer transporting the thin-walled floating dock during travel is directly transmitted to the thin-walled floating dock through the vehicle frame, causing local stress on the thin-walled floating dock, leading to the propagation of internal cracks and affecting durability.
[0005] To solve the above problems, this utility model is achieved through the following technical solution:
[0006] A support device for facilitating the transportation of thin-walled floating docks includes a support frame and a buffer layer;
[0007] The shape of the support frame matches the cross-sectional shape of the thin-walled floating dock. Multiple support crossbars are installed inside the support frame. The length direction of the support crossbars is parallel to the width direction of the support frame. Both ends of the support crossbars are connected to the support frame. The multiple support crossbars are arranged along the length direction of the support frame. The spacing between two adjacent support crossbars is equal to the span of the thin-walled floating dock.
[0008] The buffer layer is set on the frame, and the support frame is set on the buffer layer.
[0009] To better realize this utility model, further optimizations are made to the above structure. The buffer layer includes multiple buffer components, which are arranged at equal intervals along the length direction of the support frame.
[0010] The buffer assembly includes multiple sleepers with rectangular cross-sections. The length direction of the sleepers is parallel to the width direction of the support frame. The multiple sleepers are arranged parallel to each other and at equal intervals along the length direction of the support frame.
[0011] To better realize this utility model, the above structure is further optimized by providing a protective layer on the support frame for protecting the thin-walled pontoon dock.
[0012] To better realize this utility model, the above structure is further optimized. The protective layer is made of rubber material and is laid on the support frame.
[0013] To better realize this utility model, further optimization is made to the above structure. The bottom of the support frame is provided with multiple support longitudinal bars. The length direction of the support longitudinal bars is parallel to the length direction of the support frame, and the multiple support longitudinal bars are arranged at equal intervals along the width direction of the support frame.
[0014] The staggered positions of the support crossbar and support longitudinal bar are locked and fixed by connectors.
[0015] To better realize this utility model, the above structure is further optimized. Two limiting blocks are provided on the support crossbar. The two limiting blocks are respectively located near the two ends of the support crossbar, and the distance between the two limiting blocks is equal to the width of the frame.
[0016] Compared with the prior art, this utility model has the following advantages:
[0017] The support device provided by this utility model achieves flexible buffering through a buffer layer placed between the vehicle frame and the support frame, thereby reducing the rigid impact of vehicle frame vibration on the support frame during transportation and reducing the impact of vehicle frame vibration on the thin-walled floating dock. Furthermore, the support frame contains multiple support crossbars, with the spacing between two adjacent support crossbars equal to the span of the thin-walled floating dock. This ensures that adjacent support points of the thin-walled floating dock can be placed on adjacent support crossbars, guaranteeing that the overall load of the thin-walled floating dock can be stably transmitted to the support frame. This results in uniform stress on the bottom of the thin-walled floating dock, ensuring stability during trailer transportation of the thin-walled floating dock and preventing localized stress on the thin-walled floating dock caused by vibrations generated during trailer operation, which could lead to the propagation of internal cracks.

[0031] In the embodiments of this application, such as Figures 1 to 3 As shown, the support device includes a support frame 1 and a buffer layer 2; wherein,
[0032] The shape of the support frame 1 matches the cross-sectional shape of the thin-walled floating dock 4. In this embodiment, both the shape of the support frame 1 and the cross-sectional shape of the thin-walled floating dock 4 are rectangular. See [link to relevant documentation]. Figure 1 ;
[0033] The length direction of the support frame 1 is parallel to the length direction of the vehicle frame 5. The thin-walled floating dock 4 can be placed on the support frame 1, and when the thin-walled floating dock 4 is placed on the support frame 1, the length direction of the thin-walled floating dock 4 is parallel to the length direction of the support frame 1. See [link / reference]. Figure 2 ;
[0034] The support frame 1 has multiple support crossbars 11 inside. The length direction of the support crossbars 11 is parallel to the width direction of the support frame 1. Both ends of the support crossbars 11 are connected to the support frame 1. The multiple support crossbars 11 are arranged along the length direction of the support frame 1. See [reference needed] Figure 1 ;
[0035] The spacing between two adjacent support crossbars 11 is equal to the span of the thin-walled floating dock 4, so that two adjacent support points of the thin-walled floating dock 4 can be placed on two adjacent support crossbars 11. See [reference needed]. Figure 2 ;
[0036] The buffer layer 2 is placed between the frame 5 and the support frame 1.
[0037] Before transporting the thin-walled pontoon dock 4, the staff can first place the buffer layer 2 on the frame 5, and then hoist the support frame 1 onto the frame 5 so that the support frame 1 is placed stably on the buffer layer 2, with the length direction of the support frame 1 parallel to the length direction of the frame 5.
[0038] Subsequently, the thin-walled floating dock 4 can be hoisted onto the support frame 1, and the support points of the thin-walled floating dock 4 can be aligned with the positions of the support crossbars 11 in the support frame 1 to achieve support for the thin-walled floating dock 4.
[0039] During the transportation of the thin-walled floating dock 4, the buffer layer 2 can achieve flexible buffering to reduce the rigid impact of the chassis 5 vibration on the support frame 1 during the transportation process, thereby reducing the impact of the chassis 5 vibration on the thin-walled floating dock 4.
[0040] Furthermore, the aforementioned support crossbar 11 can stably support the thin-walled floating dock 4, ensuring that the overall load of the thin-walled floating dock 4 can be stably transmitted to the support frame 1, so that the bottom of the thin-walled floating dock 4 is evenly stressed, thereby ensuring the stability of the trailer transportation of the thin-walled floating dock 4 and avoiding the occurrence of internal crack expansion of the thin-walled floating dock 4 due to vibration generated during transportation.
[0041] Preferably, the aforementioned supporting crossbar 11 is an I-beam, and its upper flange is a supporting plate for supporting the thin-walled floating dock 4. The width of the upper flange is greater than the width of the inner thin wall at the support point of the thin-walled floating dock 4 (the thickness of the concrete at the support point). See [reference needed]. Figure 2 The concrete between two adjacent cavities is called the inner thin wall. The inner thin wall is supported by the upper wing plate to better support the thin-walled floating dock 4.
[0042] The aforementioned support frame 1 is made of four channel steels spliced together. When installing the support frame 1, the four channel steels can be hoisted onto the frame 5 in sequence for installation, so as to reduce the difficulty of hoisting the support frame 1.
[0043] Furthermore, the support frame 1, which is spliced from four channel steels, can be adjusted according to the size of the thin-walled floating dock 4 to better support the thin-walled floating dock 4.
[0044] It is worth noting that the interior of the thin-walled floating dock 4 is divided into multiple cavities by multiple inner thin walls, see [link to relevant documentation]. Figure 2 , Figure 2The thin-walled floating dock 4 shown in the figure is a cross-sectional view of the thin-walled floating dock 4; each cavity is filled with high-density polystyrene foam, and the distance between two adjacent inner thin walls is the span of the thin-walled floating dock 4, that is, the distance between two adjacent inner thin walls matches the distance between two adjacent support crossbars 11.
[0045] When hoisting the thin-walled floating dock 4, the position of the thin-walled floating dock 4 can be adjusted so that multiple thin walls in the thin-walled floating dock 4 correspond one-to-one with multiple supporting crossbars 11, so as to better support the thin-walled floating dock 4 and enable the thin-walled floating dock 4 to transfer the load to the supporting crossbars 11.
[0046] In some embodiments, the buffer layer 2 described above includes a plurality of buffer components, which are arranged at equal intervals along the length direction of the support frame 1.
[0047] The buffer assembly includes multiple rectangular sleepers, the length of which is parallel to the width of the support frame 1. These sleepers are arranged parallel and at equal intervals along the length of the support frame 1. (See [reference]). Figures 1 to 3 ;
[0048] Sleepers are a type of wood material. In this embodiment, sleepers with a cross-section of 200×200mm are used. They have a certain degree of elasticity and flexibility, which can reduce the direct rigid impact of the vibration of the vehicle frame 5 on the support frame 1 during trailer transportation, and play a role in buffering and protecting the thin-walled floating dock 4.
[0049] The sleeper structure is simple, easy to disassemble and replace, and can adapt to the transportation of thin-walled floating docks of different sizes and structures.
[0050] In some embodiments, the support frame 1 is provided with a protective layer 3 for protecting the thin-walled pontoon dock 4. The protective layer 3 absorbs the vibration of the frame 5 and plays a role in buffering and shock absorption. As an intermediary between the thin-walled pontoon dock 4 and the support frame 1, it can effectively disperse the local pressure at the bottom of the thin-walled pontoon dock 4 and avoid “point contact” causing damage or cracks to the outer thin wall of the thin-walled pontoon dock 4.
[0051] Preferably, the protective layer 3 is made of rubber material and is laid on the top of the support frame 1. The protective layer 3 made of rubber material has a large coefficient of friction, which increases the friction between the thin-walled pontoon dock 4 and the support frame 1 and plays a good anti-slip role. In addition, the laid protective layer 3 is easy to replace and inexpensive, and can be directly replaced after damage.
[0052] In some embodiments, the bottom of the support frame 1 is provided with a plurality of support rods 12, the length direction of the support rods 12 is parallel to the length direction of the support frame 1, and the plurality of support rods 12 are arranged at equal intervals along the width direction of the support frame 1.
[0053] The staggered positions of the support crossbar 11 and the support longitudinal bar 12 are locked and fixed by connectors to make the structure of the support device more stable.
[0054] It is worth noting that the aforementioned support longitudinal bar 12 is an I-beam. At the intersection of the support cross bar 11 and the support longitudinal bar 12, the lower flange of the support cross bar 11 and the upper flange of the support longitudinal bar 12 are provided with corresponding through holes. The connector can pass through the corresponding through holes on the lower flange of the support cross bar 11 and the upper flange of the support longitudinal bar 12 and be locked, thereby achieving the locking and fixing of the support cross bar 11 and the support longitudinal bar 12.
[0055] The connecting component is a bolt, which allows for quick assembly and disassembly of the support crossbar 11 and the support longitudinal bar 12, and can also be used to tighten the support crossbar 11 and the support longitudinal bar 12 to ensure the structural strength of the support device.
[0056] In some embodiments, two limiting blocks 13 are provided on the support crossbar 11, and the two limiting blocks 13 are respectively located near both ends of the support crossbar 11. See [reference needed] Figure 1 and Figure 3 Furthermore, the distance between the two limiting blocks 13 is equal to the width of the frame 5;
[0057] When the support frame 1 is placed on the frame 5, the two limiting blocks 13 on the support crossbar 11 can be respectively locked on both sides of the frame 5 to play a limiting role and ensure the position of the support frame 1 and the frame 5.
[0058] Preferably, the aforementioned limiting block 13 includes a fixed plate and a limiting plate, one end of the limiting plate is fixedly mounted on the fixed plate, and the plane of the limiting plate is perpendicular to the plane of the fixed plate.
[0059] When installing the limiting block 13, the workers can fix the fixing plate to the support crossbar 11 with bolts. At this time, the fixing plate is completely in contact with the lower surface of the support crossbar, and the limiting plate extends downward from both sides of the frame 5. The plane where the limiting plate is located is perpendicular to the side of the frame 5, ensuring the structural strength of the limiting block 13 and ensuring the limiting effect on the support frame 1.
[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
