Description

Technical Field

[0001] This invention relates to the field of side tube installation, and more specifically to a bracket tooling for installing side tubes on a segmented curved outer plate. Background Technology

[0002] The pre-outfitting stage is a crucial part of shipbuilding. It refers to the process of pre-installing related equipment and systems before the various hull sections are assembled. Among the components of this stage, side pipe installation is a vital part. Side pipes are external pipes typically installed on the sides of the ship, used to discharge wastewater, sewage, oil, seawater, etc., into the ocean or to introduce seawater into the ship for various purposes. The outer plates of the sections containing the side pipes are curved slopes. Installation requires drilling holes in these slopes, then lifting the side pipes from below. Because the weight of side pipes varies from large to small, they must be installed from bottom to top through the holes, which are only 4-8mm larger than the pipes. Furthermore, the installation requires precise positioning, necessitating multiple adjustments and spot welding for final positioning. Side pipes larger than DN200 cannot be installed manually; the largest side pipe, DN750, weighs over 500 kg.

[0003] The current installation method involves using a crane to lift and maintain the height of the side tubes and adjust their position. Because precise installation is required, the process is slow and occupies crane resources for extended periods; without a crane, construction is impossible. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of low installation efficiency of side tubes in the prior art, and to provide a curved outer plate side tube installation hanger tooling.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a segmented curved outer plate side tube installation hanger fixture, which includes several support columns, a lifting part, and a fixing part; the lifting part is connected to the support columns, and the support columns can move up and down relative to the lifting part to adjust the height of the support position of the support columns; the lifting part is used to suspend heavy objects; one end of the fixing part is connected to the lifting part, and the other end is connected to the curved outer plate, for fixing the position of the lifting part and the support columns.

[0007] In this design, the lifting section and the fixing section constitute the main components of the gantry fixture for installing side tubes on the segmented curved outer plate. On one hand, by movably connecting the lifting section to the support columns, multiple support columns can be moved up and down relative to the lifting section, thereby adjusting the height of the support positions of the support columns and ensuring that the lifting section remains horizontal on the curved outer plate. On the other hand, the fixing section secures the entire fixture to the edge of the curved outer plate, thus fixing the fixture on the curved outer plate and allowing it to stably suspend the side tubes to be installed.

[0008] Preferably, the hoisting part includes a frame and a movable connection structure, the support column and the frame are connected at the support position through the movable connection structure, and the support column can move up and down or be fixed relative to the movable connection structure.

[0009] In this solution, the frame of the hoisting unit is connected to the support column by a movable connection structure. The support column can move up and down relative to the movable connection structure, thereby adjusting the height of the support column's support position. The support column can be fixed on the movable connection structure, thereby fixing the position of the hoisting unit and keeping the hoisting unit in a horizontal state.

[0010] Preferably, the movable connection structure includes a cylindrical tube with a through hole, which is fitted onto the outside of the support column and can slide along the vertical direction of the support column; the support column has a plurality of through holes evenly arranged in the vertical direction, the through holes of the support column are adapted to the through holes of the cylindrical tube and are connected by a fixing pin for adjusting the height of the cylindrical tube; the cylindrical tube is connected to the frame by welding.

[0011] In this design, by sleeved with a cylindrical tube on the outside of the support column and connecting the cylindrical tube to the hoisting unit, the support column can be moved up and down relative to the hoisting unit. By evenly arranging several through holes in the vertical direction of the support column, the cylindrical tube can be fixed at different positions with fixing pins, thereby adjusting the height of the support column's support position and keeping the hoisting unit horizontal.

[0012] Preferably, a plate is added between the contact surfaces of the cylindrical tube and the hoisting part.

[0013] In this solution, by adding a plate between the contact surfaces of the cylindrical tube and the hoisting part, the contact area between the cylindrical tube and the hoisting part can be increased, thereby increasing the strength of the connection.

[0014] Preferably, the bottom of the support column is connected to a movable base, and the movable base is rotatably connected to the support column;

[0015] Alternatively, the bottom of the supporting column is connected to a movable base, and the supporting column is connected to the movable base by a screw rod;

[0016] Alternatively, the supporting column is connected to the movable base via a connecting rod, the connecting rod is connected to the lead screw of the supporting column, and the movable base is rotatably connected to the connecting rod.

[0017] In this design, a movable base is installed at the bottom of the support column. This movable base is rotatably connected to the support column, allowing it to rotate around the connection point. This enables the movable base to accommodate surfaces with varying curvatures, thus better conforming to the outer curved plate surface and enhancing the stability of the tooling on the curved surface. Furthermore, a screw is installed between the support column and the movable base. By controlling the screw's respective screw advance amounts, further fine-tuning can be achieved beyond the initial coarse adjustment between the lifting section and the support column. This allows the lifting section to maintain a more precise level, further enhancing the stability of the suspended side tube.

[0018] Preferably, the fixing part includes a fixing rod, one end of which is rotatably connected to the hoisting part, and the other end of which is connected to the curved outer plate.

[0019] In this solution, the fixed rod is rotatably connected to the hoisting part, which can adjust the angle between the fixed part and the hoisting part. This allows the fixed part to be fixed to the edge of the curved outer plate while adapting to the angle between the tooling and the fixed part at different positions on the curved outer plate, ensuring that the hoisting part remains horizontal.

[0020] Preferably, the other end of the fixing rod is clamped and fixed to the edge of the curved outer plate by an edge fixing member.

[0021] In this solution, the fixing rod is clamped and fixed to the edge of the curved outer plate by the edge fixing component, which can further enhance the stability of the tooling fixation.

[0022] Preferably, the edge fixing component includes a sleeve, a fastening bolt, and a clamp. The sleeve is fitted onto the fixing rod, and the clamp is an L-shaped metal plate. The short side of the L-shape of the clamp is connected to the sleeve, so that the clamp and the outer wall of the sleeve form a U-shaped structure. The U-shaped structure is fastened to the edge of the curved outer plate, and a fastening bolt is provided on the long side of the L-shape of the clamp for clamping and fixing the sleeve to the edge of the curved outer plate.

[0023] In this solution, by setting an L-shaped chuck on the fixed rod, the chuck can be clamped on the edge of the curved outer plate, and the clamping effect is further strengthened by the fastening bolts set on the chuck, so that the tooling can be placed more stably on the surface of the curved outer plate.

[0024] Preferably, the edge fastener is detachably connected to the fixing rod to be disposed at different positions on the fixing rod;

[0025] Alternatively, the length of the fixing rod can be adjusted.

[0026] In this solution, the edge fastener and the fixing rod are detachably connected, allowing the fixing rod to be connected to the edge fastener at different positions to change the length of the fixing rod, thereby adjusting the position of the tooling on the curved outer plate. Alternatively, a self-extending fixing rod can be used for length adjustment.

[0027] Preferably, the edge fixing member includes a sleeve and a fastening bolt, and the fastening bolt is provided on the upper part of the sleeve for adjusting and fixing the position of the fixing rod.

[0028] In this solution, by passing a fixing rod through the sleeve and tightening bolts, the bolts can be tightened at the required length of the fixing rod, thereby adjusting the length of the fixing rod and thus adjusting the position of the tooling on the curved outer plate.

[0029] The positive and progressive effects of this invention are as follows:

[0030] The hoisting part and fixing part of this invention constitute the main components of the gantry fixture for installing side tubes on a segmented curved outer plate. On one hand, by movably connecting the hoisting part to the support columns, multiple support columns can be moved up and down relative to the hoisting part, thereby adjusting the height of the support position of the support columns and ensuring that the hoisting part remains horizontal on the curved outer plate. On the other hand, the fixing part secures the entire fixture to the edge of the curved outer plate, thus fixing the fixture on the curved outer plate and allowing the fixture to stably suspend the side tubes to be installed.

[0047] Board 8 Detailed Implementation

[0048] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0049] This embodiment provides a bracket fixture for installing side tubes on four sides of a segmented curved outer plate, such as... Figure 1-3 As shown, the installation hanger fixture for the four side tubes of the segmented curved outer plate includes several support columns 1, a lifting part 2, and a fixing part 3. The lifting part 2 is connected to the support columns 1, and the support columns 1 can move up and down relative to the lifting part 2 to adjust the height of the support position of the support columns 1. The lifting part 2 is used to suspend heavy objects. One end of the fixing part 3 is connected to the lifting part 2, and the other end is connected to the curved outer plate 4, and it is used to fix the position of the lifting part 2 and the support columns 1.

[0050] The lifting part 2 and the fixing part 3 constitute the main components of the gantry fixture for installing the side tubes on the segmented curved outer plate 4. On the one hand, by movably connecting the lifting part 2 to the support column 1, multiple support columns 1 can be moved up and down relative to the lifting part 2, thereby adjusting the height of the support position of the support column 1, so that the lifting part 2 can remain horizontal on the curved outer plate 4. On the other hand, the fixing part 3 fixes the entire fixture to the edge of the curved outer plate 4, thereby fixing the fixture on the curved outer plate 4, so that the fixture can stably suspend the side tubes to be installed.

[0051] The hoisting unit 2 includes a frame and a movable connection structure. The support column 1 and the frame are connected at the support position through the movable connection structure. The support column 1 can move up and down or be fixed relative to the movable connection structure.

[0052] In this embodiment, all components of the supporting column 1, the hoisting part 2, and the fixing part 3 are made of alloy steel. The hoisting part 2 frame includes five crossbars, four of which are connected by fasteners to form a quadrilateral frame. Two opposite crossbars of the quadrilateral frame are each provided with a crossbar along a symmetrical axis. These two opposite crossbars have protruding iron plates with through holes through which the crossbar along the symmetrical axis passes. Positioning pins are provided at both ends of the crossbar along the symmetrical axis to prevent it from falling off. A movable lifting ring is provided on the crossbar along the symmetrical axis for suspending heavy objects.

[0053] Specifically, the movable connection structure includes a cylindrical tube 5, which has a through hole and is fitted onto the outside of the support column 1, allowing it to slide along the vertical direction of the support column 1; the support column 1 has several through holes evenly arranged in the vertical direction, the through holes of the support column 1 are adapted to the through holes of the cylindrical tube 5, and are connected by a fixing pin to adjust the height of the cylindrical tube 5; the cylindrical tube 5 is connected to the frame by welding.

[0054] Therefore, by sleeved with a cylindrical tube 5 on the outside of the support column 1 and connecting the cylindrical tube 5 to the hoisting part 2, the support column 1 can be moved up and down relative to the hoisting part 2. By evenly arranging several through holes in the vertical direction of the support column 1, the cylindrical tube 5 can be fixed in different positions with fixing pins, thereby adjusting the height of the support position of the support column 1 and keeping the hoisting part 2 in a horizontal state.

[0055] In this embodiment, the movable connection structure uses a cylindrical tube 5 that engages with multiple vertical openings on the support column 1, with the support column 1's position adjusted via pins. Other connection methods can also be used to adjust the support column 1's position, such as providing screw holes at different locations on the support column 1, or providing steps at different locations on the support column and using clamping devices. In other optional embodiments, other movable connection methods deemed suitable by those skilled in the art can also be selected.

[0056] Specifically, such as Figure 4 As shown, a plate 8 is added between the contact surfaces of the cylindrical tube 5 and the hoisting part 2.

[0057] Therefore, by adding a plate 8 between the contact surfaces of the cylindrical tube 5 and the lifting part 2, the contact area between the cylindrical tube 5 and the lifting part 2 can be increased, thereby increasing the strength of the connection.

[0058] In this embodiment, the added plate 8 is a circular steel plate with a diameter of 100mm, which increases the contact area between the cylindrical tube 5 and the lifting part 2, thereby achieving the desired weld strength. In other alternative embodiments, other plate materials 8 that are deemed suitable by those skilled in the art can also be selected.

[0059] Specifically, the bottom of the support column 1 is connected to a movable base 6, which is rotatably connected to the support column 1; alternatively, the support column 1 and the movable base 6 can be connected by a screw rod; or the two can be combined, with the support column 1 connected to the movable base 6 via a connecting rod, the connecting rod being rotatably connected to the support column 1, and the movable base 6 being rotatably connected to the connecting rod.

[0060] Therefore, by setting a movable base 6 at the bottom of the support column 1, and rotatably connecting the movable base 6 to the support column 1, the movable base 6 can rotate around the connection point as an axis. This allows the movable base 6 to meet the needs of curved surfaces with different curvatures, thereby better conforming to the outer surface of the curved plate and enhancing the stability of the tooling on the curved surface. Furthermore, by setting a screw between the support column 1 and the movable base 6, and controlling the screw's respective screw advance amount, further fine-tuning can be achieved on top of the coarse adjustment between the hoisting part 2 and the support column 1. This allows the hoisting part 2 to maintain a more precise level, further enhancing the stability of the suspended side tube.

[0061] In this embodiment, the horizontal cross-sectional area of ​​the movable base 6 gradually increases in the direction pointing vertically downward. By increasing the horizontal cross-sectional area of ​​the movable base 6 in the vertically downward direction, the contact area between the movable base 6 and the curved outer plate surface can be increased, further enhancing the stability of the tooling. Furthermore, the rotatable connection between the movable base 6 and the support column 1 can be achieved using a ball bearing, allowing the movable base 6 to rotate freely within a certain angle range. The support column 1 and the movable base 6 are connected by a lead screw, and the height of the support position can be finely adjusted by controlling the amount of screw advance. In other optional embodiments, other rotatable connection methods and height adjustment methods deemed suitable by those skilled in the art can also be selected. Preferably, the rotatable connection and the lead screw connection are combined; the support column 1 is connected to the movable base 6 via a connecting rod, the connecting rod is connected to the support column 1 via a lead screw, and the movable base 6 is rotatably connected to the connecting rod.

[0062] Specifically, the fixing part 3 includes a fixing rod 31, one end of which is rotatably connected to the hoisting part 2, and the other end of which is connected to the curved outer plate 4.

[0063] Therefore, by rotating the fixing rod 31 to the hoisting part 2, the angle between the fixing part 3 and the hoisting part 2 can be adjusted, so that while the fixing part 3 is fixed to the edge of the curved outer plate, it can adapt to the angle between the tooling and the fixing part 3 at different positions on the curved outer plate, ensuring that the hoisting part 2 remains horizontal.

[0064] In this embodiment, a crossbar protrudes from one side of the hoisting frame, and one end of the fixing rod 31 is connected to the protruding crossbar of the hoisting part 2 frame via a fixing pin, allowing the fixing rod 31 to rotate around the fixing pin as the rotation center. Furthermore, the fixing rod 31 connected to one side of the hoisting part 2 may also be equipped with a limit device. The limiting device has openings at both ends and a trapezoidal cross-section. A through hole is opened on one narrow side of the trapezoid, and a through groove is opened on one long side of the trapezoid. The horizontal bar protruding from the hoisting part 2 extends into the limiting device from the narrow side opening of the trapezoid, and a through hole is opened on the horizontal bar extending into the limiting device. One end of the fixing rod 31 extends into the limiting device from the wide side opening of the trapezoid, and a through hole is opened on the fixing rod 31 extending into the limiting device. The through holes on the horizontal bar extending into the limiting device and the through holes on the fixing rod 31 extending into the limiting device match the through holes on the narrow side of the trapezoid of the limiting device and are connected by a fixing pin. The part where the groove of the connecting rod fixing part intersects with the horizontal bar extending into the limiting device has a through hole and is connected by a fixing pin, so that the limiting device can rotate around the fixing pin as the rotation center. The limiting device can, on the one hand, limit the angle between the lifting part 2 and the fixing rod 31, preventing the angle from being too large and affecting the stability of the tooling fixation; on the other hand, by connecting the limiting device to both the frame of the lifting part 2 and the fixing rod 31, the connection strength between the fixing rod 31 and the lifting part 2 can be strengthened. In other optional embodiments, other rotational connection methods deemed suitable by those skilled in the art can also be selected.

[0065] Specifically, the other end of the fixing rod 31 is clamped and fixed to the edge of the curved outer plate 4 by the edge fixing member 7. The edge fixing member 7 includes a sleeve 71, a fastening bolt 72, and a clamp 73. The sleeve 71 is fitted onto the fixing rod 31. The clamp 73 is an L-shaped metal plate. The short side of the L-shape of the clamp 73 is connected to the sleeve 71, so that the clamp 73 and the outer wall of the sleeve 71 form a U-shaped structure. The U-shaped structure is fastened to the edge of the curved outer plate 4. A fastening bolt 72 is provided on the long side of the L-shape of the clamp 73 for clamping and fixing the sleeve 71 to the edge of the curved outer plate 4.

[0066] Therefore, by setting an L-shaped chuck 73 on the fixed rod 31, the chuck 73 can be clamped on the edge of the curved outer plate, and the clamping effect is further strengthened by the fastening bolt 72 set on the chuck 73, so that the tooling can be placed more stably on the surface of the curved outer plate.

[0067] In this embodiment, the edge fastener 7 is fixed to the edge of the curved outer plate 4 by a U-shaped hook and by a clamping force generated by screwing in bolts, thereby strengthening the fixation. In other optional embodiments, other clamping connection methods deemed suitable by those skilled in the art can also be selected.

[0068] Specifically, the edge fastener 7 is detachably connected to the fixing rod 31 to be positioned at different locations on the fixing rod 31;

[0069] Therefore, by detachably connecting the edge fixing member 7 and the fixing rod 31, the fixing rod 31 can be connected to the edge fixing member 7 at different positions to change the length of the fixing rod 31, thereby adjusting the position of the tooling on the curved outer plate. Alternatively, a self-extending fixing rod 31 can be used for length adjustment. One end of the extendable fixing rod 31 is connected to the hoisting part 2, and the other end is connected to the curved outer plate 4.

[0070] In this embodiment, the edge fixing member 7 can be a detachable connection or a telescopic rod, or other methods that those skilled in the art deem suitable for changing the length of the fixing rod 31 can be selected.

[0071] Specifically, the edge fixing member 7 includes a sleeve 71 and a fastening bolt 72. A fastening bolt 72 is provided on the upper part of the sleeve 71 for adjusting and fixing the position of the fixing rod 31.

[0072] Therefore, by passing the fixing rod 31 through the sleeve 71 and using the fastening bolt 72, the fastening bolt 72 can be tightened at the required length of the fixing rod 31, thereby adjusting the length of the fixing rod 31 and realizing the adjustment of the position of the tooling on the four sides of the curved outer plate.

[0073] In this embodiment, the edge fastener 7 is secured to the fixing rod 31 with bolts, but it can also be secured with pins, clamps, or other methods. In other optional embodiments, other methods of securing the fixing rod 31 that are deemed suitable by those skilled in the art can also be selected.

[0074] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
