Description

Technical Field

[0001] The present invention relates to the technical field of hull splicing and assembling, and in particular to special equipment for splicing and assembling a dragon boat hull. Background Art

[0002] Dragon boat racing, a traditional water sport with a profound cultural heritage, is becoming increasingly popular worldwide. In the actual production of dragon boats, ground support is crucial. Traditionally, wooden stakes are driven into the ground, serving as stable support points to support the hull, planks, and other materials used in the construction of the dragon boat, ensuring structural stability and safety during construction. Traditional dragon boat production still involves multiple craftsmen working simultaneously, and the hull flipping process relies on multiple people working together. This is not only inefficient, but also carries the risk of hull deformation and damage due to unstable support.

[0003] The existing support structure cannot adapt to the complex curved surface contours of the dragon boat, and the support points are unreasonable, resulting in uneven force on the hull during flipping. There is also a lack of special auxiliary devices to assist in the flipping process, which makes the flipping operation difficult and inefficient. The ship's planks often bend and deform during the flipping and splicing process due to lack of effective support, further affecting the quality of the dragon boat.

[0004] In addition, the traditional wooden pile support method cannot be quickly installed and disassembled. The installation and disassembly of equipment require a lot of manpower, material resources and time, making the production process lengthy and inefficient, and increasing the labor intensity of the production masters. Summary of the Invention

[0006] Furthermore, the auxiliary device also includes an arc driving plate slidably mounted on the arc adjusting plate, a power device 2 for driving the arc driving plate to move, and an adjustment transmission assembly designed corresponding to the push rod; a sliding frame is slidably mounted on the mounting seat, and the sliding frame is driven to move by an adjustment screw 1 rotatably mounted on the mounting seat; an arc rack 2 is provided on the arc driving plate; the adjustment transmission assembly includes an input gear rotatably mounted on the sliding frame and intermittently meshing with the arc rack 2, an output gear coaxially fixedly connected to the input gear, and an adjustment rack fixedly mounted on the push rod and intermittently meshing with the output gear.

[0007] Furthermore, the contact structure includes a rotating frame rotatably mounted on the inner end of the corresponding top rod, a top block elastically mounted on the rotating frame, a connecting rod rotatably mounted on the top block, and a bent rod whose rod body is rotatably connected to the connecting rod and whose bottom end is rotatably mounted on the rotating frame.

[0008] Furthermore, the auxiliary device also includes a clamping frame that is rotatable and elastically mounted on the end side of the arc-shaped driving plate.

[0009] Furthermore, the support device includes a connecting plate 1 that is slidably connected to the base, a pair of extension plates symmetrically rotatably mounted on the connecting plate 1, a rotating rod rotatably mounted on the extension plate, an arc rod rotatably mounted on the top of the rotating rod, a connecting plate 2 that is rotatably connected to the two arc rods, support rods rotatably mounted on the connecting plate 2 and the arc rod at both ends, a sliding adjustment block slidably mounted on the support rod, a support block rotatably mounted on the sliding adjustment block, and a buffer belt connecting the top ends of the two support rods.

[0010] Furthermore, the sliding adjustment block is driven to move by a sliding adjustment screw that is rotatably mounted on the support rod.

[0011] Furthermore, the fixing device includes a threaded sleeve, a screw threadedly matched with the threaded sleeve, a side nail intermittently extending from the screw, a side shift device for driving the side nail to move, and an adjustment ring rotatably installed on the threaded sleeve; a plurality of embedded rods are slidably and elastically installed on the threaded sleeve, and a plurality of embedded holes are provided on the head of the screw corresponding to the embedded rod; a plurality of adjustment slots are provided on the adjustment ring corresponding to the embedded rod, and the embedded rod is slidably installed in the adjustment slot; a limiting slot is provided on the screw corresponding to the side nail.

It can effectively avoid the problem of uneven force on the hull during the flipping process, greatly reducing the risk of hull deformation and damage due to unstable support, and ensuring the structural stability and safety of the dragon boat during the construction process.

[0015] Compared with the disadvantage of traditional wooden piles that are difficult to install and disassemble quickly, the installation and disassembly of the fixing device of the present invention is portable and efficient, which greatly reduces the investment of manpower, material resources and time costs, effectively improves production efficiency, and reduces the labor intensity of the production master.

When the boat planks are spliced with the back of the hull facing upward, the dragon boat planks are pressed against the hull to assist in supporting the dragon boat planks and reduce manpower consumption.

[0051] The working principle of this embodiment is as follows: The first step is to select several sets of the equipment according to the actual length of the dragon boat, arrange the equipment, select the location, and fix the equipment on the ground through the fixing device 4; The second step is to adjust the sliding adjustment screw 209 and the position of the sliding adjustment block 207 according to the shape of the dragon boat hull; the dragon boat hull is placed on the buffer belt 210, and the buffer belt 210 is subjected to the load to drive the support rod 206, the second connecting plate 205, the arc rod 204 and the rotating rod 203 to rotate in a chain manner, so that the overall structure fits the shape of the dragon boat hull better. The dragon boat hull presses the buffer belt 210 and is supported by the support block 208; In the third step, when the dragon boat hull needs to be flipped, according to the shape of the dragon boat hull, the motor 1 3021 is started to drive the arc adjustment plate 301 to move and the mounting seat 304 to slide. After the mounting seat 304 moves to a position convenient for clamping the dragon boat hull, the adjusting screw 2 3045 is rotated to fix the position of the mounting seat 304; then the adjusting screw 1 3042 is rotated, and the sliding frame 3041 drives the input gear 3061 to move, so that the input gear 3061 is engaged with the arc rack 2 3031; Start the second motor 3091, adjust the second gear 3094 to rotate and drive the second arc-shaped rack 3031 to move, thereby driving the top rod 305 to move toward the dragon boat hull, so that the contact structure 307 contacts the dragon boat hull; if the dragon boat hull is in a back-up position, the top block 3072 of the contact structure 307 contacts and is squeezed by the edge of the dragon boat hull, thereby driving the curved rod 3074 to rotate through the connecting rod 3073, and the curved rod 3074 hooks the edge of the dragon boat hull and lifts it to achieve the effect of clamping the dragon boat hull; if the dragon boat hull is in an upright position, the top blocks 3072 of the two sets of contact structures 307 squeeze the dragon boat hull at the same time, which can achieve the effect of clamping the dragon boat hull; After the dragon boat hull is clamped, the push rod 305 stops moving; the motor 1 3021 is started, the arc-shaped adjustment plate 301 rotates, and the two push rods 305 move simultaneously, driving the dragon boat hull to flip; after the dragon boat hull flips, the overall structure of the support device 2 automatically deforms to fit the flipped dragon boat hull; In the fourth step, after the dragon boat hull is flipped, the adjusting screw rod 1 3042 is rotated, the sliding frame 3041 moves, the input gear 3061 is disengaged from the arc rack 2 3031, and the push rod 305 returns to its original position under the action of the spring reset.

[0052] When the back of the dragon boat hull is facing upward, the clamping frame 308 is rotated outward to place the dragon boat deck to be assembled between the clamping frame 308 and the arc-shaped driving plate 303. This can assist in supporting the dragon boat deck when it is pushed against the hull, reducing manpower consumption.
