Description

Technical Field

[0001] This utility model relates to the field of ship deck welding technology, and in particular to a ship deck welding structure. Background Technology

[0002] The deck is an important component of the hull. It is a planar structure above the inner bottom plate in the ship's structure. It is used to cover the internal space of the ship and divide it horizontally into layers. The deck is a steel plate on the ship beam that divides the hull into upper, middle and lower layers. Ship decks require welding during the manufacturing process.

[0003] However, it is worth considering that when the existing automatic welding equipment for ship decks is in use, after the welding of a rib is completed, the staff needs to readjust the position of the deck and move the position to be welded on the deck to be directly under the welding equipment. Due to the large weight of the deck, the repeated movement of the deck is time-consuming and laborious, and affects the welding efficiency.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose a ship deck welding structure to solve the problem of the time-consuming and labor-intensive nature of repeatedly moving the deck.

[0006] To achieve the above objectives, this utility model provides a ship deck welding structure, including a base, on which several support plates for supporting the deck are fixedly connected, and two movable seats are provided above the base. A position adjustment component for driving the movable seats to translate and lift is installed on the base.

[0007] Two welding heads are provided between the two movable seats. A movable plate is fixedly connected to the top of the welding head. A lead screw and a guide column pass through the movable plate. The lead screw and the movable plate are connected by a threaded connection. Side plates are rotatably connected to both ends of the lead screw. A spacing adjustment component is provided on the movable seat for adjusting the spacing between two adjacent side plates.

[0008] Two servo motors are provided on the top of the base. The servo motors are fixedly connected to the corresponding side plates, and the output ends of the two servo motors are fixedly connected to two lead screws respectively. A limiting unit for limiting the guide column is installed on the side plate.

[0009] Preferably, the limiting unit includes sliders fixedly installed at both ends of the guide post, a groove is provided on the side of the side plate facing the guide post, and the slider is located in the corresponding groove. A first hydraulic telescopic rod is fixedly connected to the side plate, and a first arc-shaped plate for pressing the guide post is fixedly connected to the telescopic end of the first hydraulic telescopic rod.

[0010] Preferably, the spacing adjustment component includes two second hydraulic telescopic rods fixedly installed on the movable base. The telescopic ends of the second hydraulic telescopic rods are fixedly connected to a support portion, and the support portion is fixedly connected to the corresponding side plate.

[0011] Preferably, two clamping plates are provided above the movable seat, and a third hydraulic telescopic rod is provided on the side of the two adjacent clamping plates that are far apart. The third hydraulic telescopic rod is fixedly connected to the movable seat, and the telescopic end of the third hydraulic telescopic rod is fixedly connected to the corresponding clamping plate.

[0012] Preferably, the position adjustment component includes a guide bar disposed below the movable seat, two guide grooves are opened on the base, and the guide bar is located in the corresponding guide groove. Two support columns are fixedly connected to the top of the guide bar, and a fourth hydraulic telescopic rod is fixedly connected to the support column. A pressing plate is fixedly connected to the telescopic end of the fourth hydraulic telescopic rod, and the bottom of the pressing plate is in contact with the top of the base. The support column passes through the corresponding movable seat, and a pressing unit adapted to the support column is installed on the movable seat.

[0013] Preferably, the pressing unit includes two fifth hydraulic telescopic rods fixedly installed on the movable base. The telescopic ends of the fifth hydraulic telescopic rods are fixedly connected to a second arc-shaped plate, and the second arc-shaped plate is in contact with the corresponding support column.

[0014] The beneficial effects of this utility model are as follows: The worker places the deck to be welded on top of the support plate, and then places the rib to be welded on top of the deck. The position adjustment component drives the moving seat to translate and rise / fall, moving the two welding heads to both sides of the rib. The worker drives the guide column to rotate around the lead screw. The guide column drives the welding head to rotate via a movable plate, changing the tilt angle of the welding head so that it faces the connection between the deck and the rib. After the guide column is positioned, it is limited by a limiting unit. The side plate is driven to move via a spacing adjustment component. The side plate can then be moved by the lead screw and guide column. The moving welding head moves horizontally to the preset welding position. Then, the servo motor drives the lead screw to rotate, which in turn drives the moving plate and welding head to move relative to the guide column and deck. The welding head then welds the connection between the deck and the rib. After welding, the worker places the next rib to be welded on top of the deck. The position adjustment component then drives the moving seat to move horizontally and vertically, so that the two welding heads move to both sides of the next rib, and the next welding can begin. This eliminates the need to repeatedly adjust the position of the deck and allows for simultaneous welding of both sides of the rib, thus improving welding efficiency. Attached Figure Description

[0023] This specification provides one or more embodiments of a ship deck welding structure, such as... Figure 1 and Figure 2 As shown, it includes a base 1, on which several support plates 2 for supporting the deck are fixedly connected. Two movable seats 3 are provided above the base 1. A position adjustment component for driving the movable seats 3 to move horizontally and vertically is installed on the base 1.

[0024] Two welding heads 4 are provided between the two movable seats 3. A movable plate 5 is fixedly connected to the top of the welding head 4. A lead screw 6 and a guide post 7 pass through the movable plate 5. The lead screw 6 and the movable plate 5 are connected by a threaded connection. Side plates 8 are rotatably connected to both ends of the lead screw 6. A spacing adjustment component is provided on the movable seat 3 for adjusting the spacing between two adjacent side plates 8.

[0025] Two servo motors 9 are mounted on top of the base 1. The servo motors 9 are fixedly connected to the corresponding side plates 8, and the output ends of the two servo motors 9 are fixedly connected to two lead screws 6 respectively. A limiting unit for limiting the guide column 7 is installed on the side plate 8. The operator places the deck to be welded on top of the support plate 2, and then places the rib to be welded on top of the deck. The position adjustment component drives the moving seat 3 to translate and lift, so that the two welding heads 4 move to both sides of the rib. The operator drives the guide column 7 to rotate around the lead screw 6. The guide column 7 drives the welding head 4 to rotate through the movable plate 5, changing the tilt angle of the welding head 4 so that the welding head 4 faces the connection between the deck and the rib. After the position of the guide column 7 is adjusted, the limiting unit controls the guide column 7. The guide column 7 is positioned to limit the movement of the side plate 8 via the spacing adjustment component. The side plate 8 then drives the welding head 4 to move horizontally via the lead screw 6 and guide column 7, so that the welding head 4 moves to the preset welding position. The servo motor 9 then drives the lead screw 6 to rotate, which in turn drives the movable plate 5 and the welding head 4 to move relative to the guide column 7 and the deck. The welding head 4 is used to weld the connection between the deck and the rib. After welding, the worker places the next rib to be welded on top of the deck. The position adjustment component drives the movable seat 3 to move horizontally and vertically, so that the two welding heads 4 move to both sides of the next rib, and the next welding can begin. This eliminates the need to repeatedly adjust the position of the deck and allows for simultaneous welding of both sides of the rib, improving welding efficiency.

[0026] In embodiments of this utility model, such as Figure 2 and Figure 3As shown, the limiting unit includes sliders 10 fixedly installed at both ends of the guide post 7. A groove 11 is provided on the side of the side plate 8 facing the guide post 7, and the sliders 10 are located within the corresponding groove 11. A first hydraulic telescopic rod 13 is fixedly connected to the side plate 8, and the telescopic end of the first hydraulic telescopic rod 13 is fixedly connected to a first arc-shaped plate 12 for pressing the guide post 7. The spacing adjustment component includes two second hydraulic telescopic rods 14 fixedly installed on the movable seat 3. A support part 15 is fixedly connected to the telescopic end of the second hydraulic telescopic rod 14, and the support part 15 is fixedly connected to the corresponding side plate 8. Two clamping plates 16 are provided above the movable seat 3, and a third hydraulic telescopic rod 17 is provided on the side of the two adjacent clamping plates 16 that are far apart. The third hydraulic telescopic rod 17 and the movable seat 3 are connected to the first arc-shaped plate 12 for pressing the guide post 7. The moving seat 3 is fixedly connected, and the telescopic end of the third hydraulic telescopic rod 17 is fixedly connected to the corresponding clamping plate 16. When the guide column 7 rotates around the lead screw 6, the guide column 7 drives the slider 10 to slide in the slide groove 11. When it is necessary to limit the guide column 7, the first arc plate 12 is moved by the first hydraulic telescopic rod 13 so that the first arc plate 12 presses the guide column 7, thereby fixing the slider 10 in the slide groove 11 and completing the limit of the guide column 7. The support part 15 and the side plate 8 are moved by the second hydraulic telescopic rod 14 to adjust the distance between the welding head 4 and the rib. The clamping plate 16 is moved by the third hydraulic telescopic rod 17 so that the two adjacent clamping plates 16 hold the rib, thereby preventing the rib from shaking relative to the deck and improving the stability during welding.

[0027] In embodiments of this utility model, such as Figure 1 and Figure 2As shown, the position adjustment assembly includes a guide bar 18 disposed below the movable seat 3. Two guide grooves 19 are formed on the base 1, and the guide bar 18 is located within the corresponding guide groove 19. Two support columns 20 are fixedly connected to the top of the guide bar 18. A fourth hydraulic telescopic rod 21 is fixedly connected to the support column 20.

The support column 20 passes through the corresponding movable seat 3. A pressing unit adapted to the support column 20 is installed on the movable seat 3. The pressing unit includes two fifth hydraulic telescopic rods 23 fixedly installed on the movable seat 3. A second arc-shaped plate 24 is fixedly connected to the telescopic end of the fifth hydraulic telescopic rod 23. The movable seat 3 contacts the corresponding support column 20. The operator drives the movable seat 3 to slide vertically relative to the support column 20, thereby adjusting the height of the movable seat 3. After the height of the movable seat 3 is adjusted, the second arc plate 24 is moved by the fifth hydraulic telescopic rod 23 so that the second arc plate 24 presses against the support column 20, thereby fixing the second arc plate 24 and the movable seat 3 relative to the support column 20. The operator drives the guide bar 18 to slide in the guide groove 19, thereby moving the movable seat 3 horizontally. When it is necessary to position the movable seat 3, the pressing plate 22 is moved down by the fourth hydraulic telescopic rod 21 so that the pressing plate 22 presses against the top of the base 1, thereby preventing the guide bar 18 from sliding relative to the guide groove 19, thereby fixing the movable seat 3 relative to the base 1.
