The shape of the bottom end of the hull is different from the shape of the top end of the hull, making it impossible to accurately fix the hull; 2. The device is unstable when fixing large-sized hulls. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rigid support structure for shipbuilding.

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

[0005] A rigid support structure for shipbuilding includes four rectangular support frames and two fixing devices. The top and bottom ends of two adjacent support frames are connected by an upper support plate and a lower support plate, respectively. One fixing device is slidably embedded between the upper and lower support plates between two adjacent support frames, and the other fixing device is slidably embedded between the upper and lower support plates on opposite sides. The two fixing devices are staggered and slide along the length of the upper and lower support plates. Each fixing device includes a sliding frame, a first support rod, and a second support rod. The first and second support rods pass through the sliding frame at intervals from top to bottom. An inverted U-shaped clamping block and a trapezoidal support block are fixed to one end of the first and second support rods passing through the sliding frame, respectively.

[0006] Furthermore, the sliding frame includes a first connecting block and a second connecting block arranged vertically parallel and spaced apart. The first connecting block and the second connecting block are fixedly spaced from top to bottom between them. An upper support plate is embedded in the top space formed by the upper end face of the first connecting block and the opposite sides of the first and second connecting blocks located above the first connecting block. A lower support plate is embedded in the lower end face of the second connecting block and the bottom space formed by the first connecting block located below the second connecting block and the opposite sides of the second connecting block. The first and second connecting blocks are respectively provided with a first screw hole and a second screw hole spaced from top to bottom, penetrating their inner and outer sides, and the first and second screw holes are arranged opposite each other. Both the first and second support rods are provided with a threaded section and a smooth section. The smooth section is located near one end of the inverted U-shaped clamping block and the trapezoidal support block. The two ends of the threaded section are located on both sides of the sliding frame. The ends of the first and second support rods near the smooth sections are respectively threaded through the opposite first and second screw holes and screwed to the first and second connecting blocks.

[0007] Furthermore, a collar is slidably fitted on the smooth sections of both the first and second support rods. Rotation shafts, perpendicular to the first and second support rods, are provided at the top and bottom of the collars. Two auxiliary support rods are symmetrically mirrored and rotatably connected to the two rotation shafts. A fixing block is connected to the other end of each auxiliary support rod. A first fixing screw hole is provided on the vertical side of each fixing block away from the second connecting block. Four sets of second fixing screw holes, arranged in pairs, are provided on the side of the second connecting block near the collar. Two sets of second fixing screw holes are symmetrically arranged on the upper and lower sides of a second screw hole, with the two second fixing screw holes in each set vertically spaced apart.

[0008] Furthermore, the widths of the upper and lower support plates are the same as the distance between the opposite sides of the first and second connecting blocks.

[0009] Furthermore, multiple second positioning screw holes are evenly distributed along the length of the upper and lower support plates, and first positioning screw holes penetrating the upper and lower end faces are provided on the first and second connecting blocks. The first positioning screw holes and the second positioning screw holes have the same size, and their central axes are located in the same vertical plane.

[0010] Furthermore, two sets of fixing nuts are screwed onto the first support rod and the second support rod, with each set located on one side of the first connecting block and the second connecting block respectively. In use, the fixing nuts are tightly fitted to the first connecting block and the second connecting block.

[0011] Furthermore, the support frame includes a square column and a base plate. The square column is vertically disposed on the upper surface of the base plate, and the two ends of the lower support plate are fixedly connected to the bottom end of the square column.

[0012] Furthermore, a vertically downward-extending embedded foot is provided on the lower end surface of the base plate, and multiple sets of barbs are provided on both sides of the embedded foot from top to bottom, with two barbs in each set arranged in a mirror image symmetrically.

[0013] Furthermore, a handle is provided at the end of the first support rod and the second support rod located outside the first connecting block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, this invention involves moving the fixing device to the location of the hull to be secured. The U-shaped clamps hold the top edge of the hull. Bolts are then inserted through the first positioning screw hole to the corresponding second positioning screw hole, fixing the first connecting block to the first connecting block and the second connecting block to the second connecting block, thus securing the fixing device. Rotating the handle allows the threaded part of the first support rod to rotate within the first screw hole, adjusting the extension and retraction of the first support rod. This causes the U-shaped clamps to hold and support the top edge of the hull. Similarly, the threaded part of the second support rod rotates within the second screw hole, adjusting the extension and retraction of the second support rod. This allows the trapezoidal support block to fit against the bottom of the hull. Through the clamping of the four fixing devices, both the top and bottom of the hull are supported, making the hull more stable during construction. After adjusting the first and second support rods, the U-shaped clamps hold and support the top edge of the boat, and the trapezoidal support blocks fit against the bottom of the boat. At this time, tighten the fixing nuts on both sides of the first and second connecting blocks so that they are close to the sides of the first and second connecting blocks. Then, adjust the position of the collar according to the extension and retraction position of the first and second support rods. When the bolt passes through the first fixing screw hole to the matching second fixing screw hole, the collar can be fixed. The fixed collar can provide support for the first and second support rods, making them less prone to bending. During installation, the pre-embedded anchors are pre-buried in the ground. The barbs can increase the connection force between the pre-embedded anchors and the ground, making the support frame more stable. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] like Figure 1-4As shown, a rigid support structure for shipbuilding includes four rectangular support frames 1 and two fixing devices. Each support frame 1 includes a square column 101 and a base plate 102. The square column 101 is vertically mounted on the upper surface of the base plate 102. The top and bottom ends of two adjacent square columns 101 are connected by an upper support plate 2 and a lower support plate 3, respectively. The two ends of the lower support plate 3 are fixedly connected to the bottom ends of the square columns 101. One fixing device is slidably embedded between the upper support plate 2 and the lower support plate 3 between two adjacent support frames 1, and the other fixing device is slidably embedded between the upper support plate 2 and the lower support plate 3 on opposite sides. The device is positioned in a staggered manner, allowing the fixing device to slide along the length of the upper support plate 2 and the lower support plate 3. The fixing device includes a sliding frame 4, a first support rod 11, and a second support rod 13. The first and second support rods 11 and 13 are spaced apart and pass through the sliding frame 4 from top to bottom. Two sets of fixing nuts 26, arranged in pairs, are screwed onto both the first and second support rods 11 and 13. The two sets of fixing nuts 26 are located on opposite sides of the first connecting block 5 and the second connecting block 6, respectively. During use, the fixing nuts 26 are tightly fitted to the first and second connecting blocks 5 and 6. One end of the first and second support rods 11 and 13 passing through the sliding frame 4 is respectively fixed with an inverted U-shaped clamping block 12 and a trapezoidal support. The sliding frame 4 includes a first connecting block 5 and a second connecting block 6 arranged vertically parallel and spaced apart. A first connecting block 7 and a second connecting block 8 are fixed between the first connecting block 5 and the second connecting block 6 from top to bottom. The widths of the upper support plate 2 and the lower support plate 3 are the same as the distance between the opposite sides of the first connecting block 5 and the second connecting block 6. The upper support plate 2 is embedded in the top space formed by the upper end face of the first connecting block 7 and the opposite sides of the first connecting block 5 and the second connecting block 6 located above the first connecting block 7. The lower support plate 3 is embedded in the lower end face of the second connecting block 8 and the space between the first connecting block 5 and the second connecting block 6 located below the second connecting block 8. Within the bottom space enclosed by the opposite sides of the connecting block 6; the first connecting block 5 and the second connecting block 6 are respectively provided with a first screw hole 9 and a second screw hole 10 that penetrate their inner and outer sides from top to bottom, and the first screw hole 9 and the second screw hole 10 are arranged opposite to each other; the first support rod 11 and the second support rod 13 are each provided with a threaded section 15 and a smooth section, the smooth section is located at one end near the inverted U-shaped clamping block 12 and the trapezoidal support block 14, the two ends of the threaded section 15 are respectively located on both sides of the sliding frame 4, and the first support rod 11 and the second support rod 13 are respectively provided with the oppositely arranged first screw hole 9 and second screw hole 10 through the smooth section, and are screwed to the first connecting block 5 and the second connecting block 6;Multiple second positioning screw holes 21 are evenly distributed along the length of the upper support plate 2 and the lower support plate 3. First positioning screw holes 20 penetrating the upper and lower end faces of both the first connecting block 7 and the second connecting block 8 are provided. The first positioning screw holes 20 and the second positioning screw holes 21 have the same size, and their central axes are located in the same vertical plane.

[0023] A further improvement is that a collar 16 is slidably fitted on the smooth sections of both the first support rod 11 and the second support rod 13. Rotation shafts 17, perpendicular to the first support rod 11 and the second support rod 13, are provided at the top and bottom ends of the collar 16. Two auxiliary support rods 18 are mirror-symmetrically and rotatably connected to the two rotation shafts 17. A fixing block 19 is connected to the other end of each auxiliary support rod 18. A first fixing screw hole 24 is provided on the vertical side of each fixing block 19 away from the second connecting block 6. Four sets of second fixing screw holes 25, arranged in pairs, are provided on the side of the second connecting block 6 near the collar 16. Two sets of second fixing screw holes 25 are symmetrically arranged on the upper and lower sides of a second screw hole 10, with two second fixing screw holes 25 in each set vertically spaced apart.

[0024] By moving the collar 16 to a suitable position between the first support rod 11 and the second support rod 13, and then fixing the collar 16 by bolting it through the first fixing screw hole 24 to the matching second fixing screw hole 25, the fixed collar 16 can provide support for the first support rod 11 and the second support rod 13. As the first support rod 11 and the second support rod 13 extend and retract, the position of the collar 16 can also be adjusted to support the first support rod 11 and the second support rod 13, making them less prone to bending. This increases the stability of the support of the first support rod 11 and the second support rod 13, making the fixing device less prone to bending and strengthening its support, thus making the fixed hull more stable. The auxiliary support rod 18 is movably connected to the collar 16 through the rotating shaft 17. By adjusting the angle of the auxiliary support rod 18, the collar 16 can be moved.

[0025] The lower end surface of the base plate 102 is provided with a vertically downward-extending embedded foot. On both sides of the embedded foot, multiple sets of barbs are arranged in pairs from top to bottom, with the two barbs in each set arranged in a mirror image symmetrically. The bottom end of the support frame 1 is provided with an embedded foot, and barbs are provided on both sides of the embedded foot. The embedded foot is pre-buried in the ground, and the barbs can increase the connection force between the embedded foot and the ground, making the support frame 1 more stable.

[0026] When the fixing device is moved to the hull where it needs to be fixed, the U-shaped clamps hold the top edge of the hull. By using bolts to pass through the first positioning screw hole 20 to the corresponding second positioning screw hole 21, the first connecting block 7 is fixed to the first connecting block 5, and the second connecting block 8 is fixed to the second connecting block 6, thereby fixing the fixing device. The fixing nut 26 can enhance the stability of the first support rod 11 and the second support rod 13.

[0027] When in use, the fixing device is moved to the hull where it needs to be fixed, and the U-shaped clamps hold the top edge of the hull. By using bolts to pass through the first positioning screw hole 20 to the corresponding second positioning screw hole 21, the first connecting block 7 is fixed to the first connecting block 5, and the second connecting block 8 is fixed to the second connecting block 6, thereby fixing the fixing device. Then, by turning the handle 27, the first support rod 11 and the second support rod 13 can be extended and retracted, so that the trapezoidal support block 14 fits against the bottom of the hull. Through the clamping of the fixing devices on all four sides, the top and bottom of the hull can be supported, making the hull more stable during construction.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
