Description

Technical Field

[0001] This utility model belongs to the field of ship sail installation technology, specifically relating to a suction-type airfoil sail bottom support structure. Background Technology

[0002] For small to medium-sized chemical tankers with piped decks, installing airfoil suction sails on the piped deck can significantly reduce main engine energy consumption and carbon emissions on routes with abundant wind resources. However, some ships use container-shaped plate structures for the sail bases, which occupy a large deck area and are structurally heavy. This is detrimental to reducing the empty ship's weight and lowering its center of gravity, negatively impacting buoyancy. Furthermore, it makes installation on the deck slope more difficult, making it challenging to precisely ensure the level of the top support surface of the sail base. Utility Model Content

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide a suction-type airfoil bottom support structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A suction-type airfoil bottom support structure includes a vertical frame and a top frame symmetrically supported by two sets of vertical frames; it also includes an adjusting bracket that can be fitted between the vertical frame and the top frame to ensure that the top of the top frame forms a horizontal support surface.

[0006] Preferably, the support frame includes a support column and a support beam, the support column is vertically fixed to the bottom of the support beam, and the top frame or the adjusting bracket is fixed to the top of the support beam.

[0007] Preferably, a set of the uprights includes at least two evenly distributed support columns.

[0008] Preferably, the support frame further includes an external reinforcing diagonal column fixed between the supporting column and the supporting beam.

[0009] Preferably, the two external reinforcing inclined columns fixed on both sides of the supporting column are combined to form a V-shaped structure.

[0010] Preferably, the support frame further includes a base into which the support column can be inserted.

[0011] Preferably, the top frame adopts a frame structure composed of horizontal columns and connecting columns, wherein the horizontal columns are parallel to the supporting beams and adjusting brackets, and the connecting columns are fixed perpendicularly to the horizontal columns.

[0012] Preferably, the connecting column includes at least end posts that fit at both ends of the horizontal column and a reinforcing column located between the two end posts.

[0013] Preferably, a reinforcing guide is connected between the reinforcing column and the supporting column. The reinforcing guide includes a U-shaped guide rail fixed to the inner side of the supporting column and an inner reinforcing inclined column fixed to the bottom of the connecting column. The bottom end of the inner reinforcing inclined column can be inserted into the U-shaped groove of the U-shaped guide rail.

[0014] Preferably, the adjusting bracket adopts a frame structure consisting of a top plate, a bottom plate, uprights and diagonal braces, wherein the uprights and diagonal braces are fixed between the top plate and the bottom plate.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention utilizes the assembly and combination of uprights, top frames, and adjusting supports to form a frame-type base. Compared to traditional container-type bases, this design effectively saves construction materials, reduces base weight, and eliminates the need for internal lighting or other auxiliary facilities. Furthermore, the adjusting supports are positioned between the uprights and top frames, allowing for flexible support of the two sets of uprights at different deck heights. This is suitable for installation on special locations such as steps and slopes, and precisely ensures the levelness of the top support surface of the top frame. Attached Figure Description

[0025] This utility model provides a suction-type airfoil sail bottom support structure, including a support frame 100, a top frame 200, and an adjusting bracket 300, among other accessories. These accessories can be selectively assembled according to actual installation needs, such as... Figure 1 As shown: At point A (upper mounting surface), two sets of uprights 100 and one set of top frame 200 are installed; at point B (sloping surface), two sets of uprights 100, one set of adjusting brackets 300 and one set of top frame 200 are installed; at point C (lower mounting surface), two sets of uprights 100, two sets of adjusting brackets 300 and one set of top frame 200 are installed.

[0026] Figure 2 The diagram shows the suction-type airfoil sail bottom support structure assembled at point B. Two sets of uprights 100 symmetrically support the top frame 200, and an adjusting bracket 300 is installed between one set of uprights 100 and the top frame 200. Thus, while keeping the support surface 201 at the top of the top frame 200 horizontal, the bottom heights of the two sets of uprights 100 are different, meaning that the two sets of uprights 100 can be supported on mounting surfaces at different heights. Figure 1 At point B, the bottom support structure of the suction-extraction airfoil will be installed on the slope.

[0027] Figure 3 The diagram shows the bottom support structure of the suction-type airfoil sail assembled at point C. Two sets of uprights 100 symmetrically support the top frame 200, and adjustment brackets 300 are installed between the two sets of uprights 100 and the top frame 200, thereby raising the height of the support surface 201 at the top of the top frame 200 at point C, so that it is the same height as the support surface 201 at the top of the top frame 200 at point B.

[0028] Continue to refer to Figure 4 As shown, the support frame 100 includes a supporting beam 102 and supporting columns 101 vertically fixed to the bottom of the supporting beam 102 (both the supporting beam 102 and the supporting columns 101 are made of square steel). Two supporting columns 101 are symmetrically arranged in the figure to achieve balanced support for the supporting beam 102. When assembling the top frame 200 or the adjusting bracket 300, parallel support is provided through the supporting beam 102.

[0029] In one feasible embodiment, to improve the stability of the support frame 100, an outer reinforcing diagonal column 103 is fixed between the support column 101 and the support beam 102. Since the span along the length of the support beam 102 is relatively large, one support column 101 is combined with two outer reinforcing diagonal columns 103, and the two outer reinforcing diagonal columns 103 symmetrically fixed on both sides of one support column 101 form a V-shaped structure, which, together with the support beam 102, constitutes a triangular support.

[0030] In yet another executable embodiment, a reinforcing guide 105 is further connected between the top frame 200 and the supporting column 101. Figure 5 As shown, the reinforcing guide 105 includes a U-shaped guide rail 106 and an inner reinforcing inclined column 107 connecting the U-shaped guide rail 106 and the top frame 200. The U-shaped guide rail 106 is fixed to the inner side of the supporting column 101, and the U-shaped guide rail 106 can be made of U-shaped steel. Although the span between the two sets of uprights 100 is small, it is necessary to ensure that the height of the two sets of uprights 100 can be adjusted independently. Therefore, two sets of symmetrical reinforcing guides 105 are connected between the two sets of uprights 100 and the top frame 200. The inner reinforcing inclined columns 107 of the two sets of reinforcing guides 105 are combined to form an inverted V-shaped structure, which also enables the uprights 100, the supporting column 101 and the inner reinforcing inclined columns 107 to maintain triangular support, further improving the stability of the uprights 100.

[0031] In addition, to facilitate the installation of the support frame 100 at various locations on the deck, a base 104 is fixed to the deck, and mounting holes for inserting the support column 101 are provided in the base 104. The base 104 is fixedly connected to the support column 101.

[0032] Referring to Figure 3, the top frame 200 adopts a frame structure consisting of horizontal columns 202 and connecting columns 203 (both horizontal columns 202 and connecting columns 203 are made of square steel). The horizontal columns 202 are parallel to the supporting beam 102 and the adjusting bracket 300, and the connecting columns 203 are fixed perpendicularly to the horizontal columns 202.

[0033] In one executable embodiment: two horizontal columns 202 are symmetrically arranged and each cooperates with two sets of uprights 100; the connecting column 203 includes at least end columns 204 that cooperate at both ends of the horizontal column 202 and a reinforcing column 205 located between the two end columns. Two reinforcing columns 205 are symmetrically arranged in the figure and are respectively cooperated above the two supporting columns 101. Based on the structure of this embodiment, the inner reinforcing inclined column 107 of the reinforcing guide 105 is preferably fixed to the bottom of the reinforcing column 205.

[0034] Referring to Figure 6, the adjusting bracket 300 adopts a frame structure consisting of a top plate 301, a bottom plate 302, uprights 303, and diagonal braces 304. The uprights 303 and diagonal braces 304 are fixed between the top plate 301 and the bottom plate 302 to ensure the stability of the structure.

[0035] The aforementioned upright frame 100 (excluding the base 104), top frame 200, and adjusting bracket 300 are all prefabricated in the factory. Among them, the U-shaped guide rail 106 is welded to the inner side of the support column 101 of the upright frame 100, and an avoidance slope is also provided at the bottom of the U-shaped guide rail 106 to prevent the U-shaped guide rail 106 from interfering with the assembly of the support column 101 and the fixed base 104. The inner reinforcing inclined column 107 is welded and fixed to the bottom of the reinforcing column 205 of the top frame 200.

[0036] refer to Figure 1 As shown, when the aforementioned suction-type airfoil bottom support structure is installed at point A:

[0037] First, fix the base 104 at point A (upper mounting surface). The specific fixing method can be to use bolts to fix the base 104 to the deck, or the base 104 can be directly welded to the deck.

[0038] Then, using cranes or other equipment, the two sets of uprights 100 are hoisted, ensuring that the bottom of the support column 101 is inserted precisely into the mounting hole in the base 104; while hoisting and installing the uprights 100, the U-shaped guide rail 106 is installed simultaneously. After the bottom of the support column 101 is inserted into the base 104, the support column 101 and the base 104 are connected by bolts or welding.

[0039] Next, the top frame 200 is hoisted using cranes and other equipment. During hoisting, ensure that the inner reinforcing inclined column 107 at the bottom of the reinforcing column 205 is inserted into the U-shaped groove of the U-shaped guide rail 106 to achieve precise guidance during the hoisting of the top frame 200. When the bottom of the top frame 200 (horizontal column 202) abuts against the top of the supporting beam 102, the top frame 200 is connected to the two sets of uprights 100 by bolts or welding. At the same time, the inner reinforcing inclined column 107 is also connected to the U-shaped guide rail 106 by bolts or welding. This completes the installation of the bottom support structure of the suction-type airfoil at point A.

[0040] refer to Figure 1 As shown, when the aforementioned suction-type airfoil bottom support structure is installed at point B:

[0041] First, fix the bases 104 at point B (slope). In the diagram, the right set of bases 104 is fixed to the slope, while the left set is on the fixed plane. To ensure the bases 104 on the slope conform to the slope surface, the bottom of these bases 104 can be beveled. The bases 104 can be fixed to the deck using bolts or directly welded to the deck.

[0042] Then, using cranes or other equipment, the two sets of uprights 100 are hoisted, ensuring that the bottom of the support column 101 is inserted precisely into the mounting hole in the base 104; while hoisting and installing the uprights 100, the U-shaped guide rail 106 is installed simultaneously. After the bottom of the support column 101 is inserted into the base 104, the support column 101 and the base 104 are connected by bolts or welding.

[0043] Next, a set of adjusting brackets 300 is hoisted to the top of the left-side upright 100 using equipment such as a crane. When the bottom plate 302 of the adjusting bracket 300 abuts against the top of the supporting beam 102, the adjusting bracket 300 and the upright 100 are connected by bolts or welding.

[0044] Finally, the top frame 200 is hoisted using a crane or other equipment. During hoisting, ensure that the inner reinforcing inclined column 107 at the bottom of the reinforcing column 205 is inserted into the U-shaped groove of the U-shaped guide rail 106 to achieve precise guidance during the hoisting of the top frame 200. When the bottom of the right horizontal column 202 of the top frame 200 abuts against the top of the supporting beam 102, and the bottom of the left horizontal column 202 of the top frame 200 abuts against the top of the adjusting bracket 300 (top plate 301), the top frame 200, the upright frame 100, and the adjusting bracket 300 are connected by bolts or welding. At the same time, the inner reinforcing inclined column 107 is also connected to the U-shaped guide rail 106 by bolts or welding. This completes the installation of the bottom support structure of the suction-type airfoil at point B.

[0045] refer to Figure 1 As shown, when the aforementioned suction-type airfoil bottom support structure is installed at point C:

[0046] First, fix the base 104 at point C (lower mounting surface). The specific fixing method can be to use bolts to fix the base 104 to the deck, or the base 104 can be directly welded to the deck.

[0047] Then, using cranes or other equipment, the two sets of uprights 100 are hoisted, ensuring that the bottom of the support column 101 is inserted precisely into the mounting hole in the base 104; while hoisting and installing the uprights 100, the U-shaped guide rail 106 is installed simultaneously. After the bottom of the support column 101 is inserted into the base 104, the support column 101 and the base 104 are connected by bolts or welding.

[0048] Next, using cranes and other equipment, the two sets of adjusting brackets 300 are hoisted to the top of the two sets of uprights 100. When the bottom plate 302 of the adjusting bracket 300 abuts against the top of the supporting beam 102, the adjusting bracket 300 and the uprights 100 are connected by bolts or welding.

[0049] Finally, the top frame 200 is hoisted using a crane or other equipment. During hoisting, ensure that the inner reinforcing inclined column 107 at the bottom of the reinforcing column 205 is inserted into the U-shaped groove of the U-shaped guide rail 106 to achieve precise guidance during the hoisting of the top frame 200. When the bottom of the top frame 200 (horizontal column 202) abuts against the top of the adjusting bracket 300 (top plate 301), the top frame 200 and the adjusting bracket 300 are connected by bolts or welding. At the same time, the inner reinforcing inclined column 107 and the U-shaped guide rail 106 are also connected by bolts or welding. This completes the installation of the bottom support structure of the suction-type airfoil at point C.

[0050] In summary, by adapting the assembly of the upright frame 100, the top frame 200, and the adjusting bracket 300 according to different installation positions, it can be ensured that the support surface 201 at the top of the top frame 200 always remains horizontal, and the multiple support surfaces 201 formed by multiple top frames 200 can also be located in the same plane at the same height.
