Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically a support frame for shipbuilding. Background Technology

[0002] In the construction of small ships, the ship deck needs to be welded to the inside of the ship's cabin. In order to ensure the normal progress of the welding operation, the ship needs to be supported. Therefore, a ship construction support frame is required.

[0003] A Chinese patent with authorization announcement number CN220718270U discloses a ship processing support device, including a bottom frame. Hinges are fixedly connected to both sides of the upper surface of the bottom frame, and a support rod is rotatably connected to each hinge block. In this invention, rotating the handle will drive the threaded rod to rotate, causing the shaft to move the bottom end of the support rod on the surface of the adjusting seat, thus adjusting the height of the support plate. Furthermore, the height of both ends of the support plate can be adjusted individually by adjusting the handle, and the height of both sides of the support plate can be adjusted via an electric telescopic rod. Therefore, this device not only allows for height adjustment but also for adjusting the deflection angle.

[0004] However, the aforementioned support device still has some problems. In practical applications, different ships have different outer surface shapes. In the existing technology, the side plates of the support frame are fixed. When encountering irregular or curved hull surfaces, the contact area will become smaller, the support will be unstable, and the welding effect of the ship will be reduced. Therefore, a support frame for ship construction is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background art, this utility model proposes a support frame for ship construction.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A support frame for shipbuilding, as described in this utility model, includes a frame body. Two sets of sliding blocks, each consisting of two blocks, are symmetrically installed on the top of the frame body. A mounting frame is installed on the top side of each sliding block. A rotating shaft is rotatably mounted between the two sides of the mounting frame. A movable block is installed on the outer side of the rotating shaft. A side clamp is installed on one side of each movable block. A rubber pad is fitted on one side of each side clamp. A worm gear is installed at one end of the rotating shaft. A support seat is installed at one end of each mounting frame. A servo motor is installed on one side of each support seat. A rotating shaft is installed at the output end of the servo motor. One end of the shaft passes through the mounting frame and is rotatably mounted inside it on one side. A worm gear is mounted on the outside of the shaft, and the worm wheel meshes with the worm gear. When the servo motor starts, it drives the shaft to rotate, which in turn causes the worm gear to rotate. The worm wheel then rotates and drives the shaft to rotate, ultimately achieving the angle adjustment of the movable block and the side clamp. Different ships have different side surface shapes and tilt angles. Through this angle adjustment function, the side clamp can closely fit the curved surface of the ship. The rubber pad plays a role in buffering and increasing friction, effectively improving the support effect on the ship, making the ship more stable on the support frame, providing a good foundation for welding operations, and reducing errors caused by ship swaying during the welding process.

[0007] Preferably, a disc is mounted on one side of the mounting bracket, and several scale lines are equidistantly engraved on one side of the disc. An indicator needle is mounted on the other end of the rotating shaft. The operator can accurately understand the adjustment angle of the side clamp by observing the scale line corresponding to the indicator needle.

[0008] Preferably, a stepper motor is installed on one side of the frame, and a bidirectional lead screw is installed at the output end of the stepper motor. One end of the bidirectional lead screw passes through the frame and is rotatably installed inside one side of the frame. A guide rod is fixed between the two sides of the frame. Movable plates are movably installed at both ends of the bidirectional lead screw and the guide rod. After the stepper motor is started, it drives the bidirectional lead screw to rotate. Since the bidirectional lead screw cooperates with the movable plates and the guide rod plays a guiding role, the two movable plates can move simultaneously to the middle or to the sides. The distance between the two movable plates can be flexibly adjusted according to the actual length of the hull, thereby achieving effective support for hulls of different lengths.

[0009] Preferably, each of the movable plates is equipped with a mounting plate on its top side, and a drive motor is installed on one side of each mounting plate. A bidirectional screw is installed at the output end of the drive motor. Two sliding grooves are symmetrically formed inside the top side of the mounting plate. Each set of sliding blocks is slidably installed inside the sliding groove in each movable plate. A screw hole is formed inside the bottom end of each sliding block. One end of the bidirectional screw passes through the screw hole and is rotatably installed inside one side of the sliding groove. When the drive motor starts, it drives the bidirectional screw to rotate. Since the bidirectional screw and the sliding block are engaged through the screw hole and the sliding block slides in the sliding groove, the two sliding blocks on the same movable plate can move simultaneously to the middle or both sides, thereby effectively fixing ships of different widths and ensuring that the ship does not move laterally on the support frame.

[0010] Preferably, a plurality of support shafts are equidistantly rotatably mounted on the bottom side of the frame, and foot brake wheels are mounted on the bottom side of the support shafts, so that the support frame can be easily moved on the ground, making it convenient for operators to move the support frame to a suitable working position and fix it according to actual needs.

[0011] Preferably, a control panel is installed on one side of the frame. The control panel is used to operate and control the electrical components inside the device. Operators can centrally control the start, stop, speed, and direction parameters of electrical components such as stepper motors, servo motors, and drive motors, thereby realizing automated control of the entire shipbuilding support frame.

[0012] The advantages of this utility model are: 1. The output shaft of the servo motor of this utility model drives the rotating shaft to rotate, which causes the outer worm to rotate, drives the worm wheel to rotate, and then drives the rotating shaft to rotate. The rotation of the rotating shaft allows the outer movable block and the side clamp to adjust their angles. Different ships have different side surface shapes and tilt angles. Through this angle adjustment function, the side clamp can closely fit the curved surface of the ship, making the ship more stable on the support frame, providing a good foundation for welding operations, and reducing the errors caused by the ship's swaying during the welding process. 2. The output shaft of the stepper motor of this utility model drives the bidirectional screw to rotate, so that the two movable plates can move to the middle or both sides at the same time. The distance between the two movable plates can be flexibly adjusted according to the actual length of the hull, thereby achieving effective support for hulls of different lengths. The output shaft of the drive motor drives the bidirectional screw to rotate, so that the two sliding blocks on the same movable plate can move to the middle or both sides at the same time, thereby achieving effective fixation of ships of different widths and ensuring that the ship will not move laterally on the support frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5As shown, a support frame for shipbuilding includes a frame body 1. Two sets of sliding blocks 2 are symmetrically installed on the top of the frame body 1. A mounting frame 201 is installed on the top side of each sliding block 2. A rotating shaft 202 is rotatably installed between the two sides of the mounting frame 201. A movable block 203 is installed on the outer side of the rotating shaft 202. A side clamping plate 204 is installed on one side of the movable block 203. A rubber pad 205 is fitted on one side of the side clamping plate 204. A worm gear 206 is installed at one end of the rotating shaft 202. A support seat 207 is installed on one bottom end of each mounting frame 201. A servo motor 208 is installed on one side of the support seat 207. A rotating shaft 209 is installed at the output end of the servo motor 208. One end of the rotating shaft 209 passes through the mounting frame 201 and is rotatably installed inside it on one side. A worm gear 210 is installed on the outer side of the rotating shaft 209, and the worm gear 206 meshes with the worm gear 210. A disc 211 is mounted on one side of the mounting bracket 201. Several scale lines 212 are equidistantly engraved on one side of the disc 211. An indicator needle 213 is mounted on the other end of the rotating shaft 202. A control panel 6 is installed on one side of the frame 1. The control panel 6 is used to control the operation of the internal electrical components of the device. During operation, in practical applications, different ships have different outer surface shapes. In the prior art, the side clamping plate 204 of the support frame is fixed. This reduces the contact area when encountering irregular or curved hull surfaces, leading to unstable support and reduced welding efficiency. When adjusting the angle of the side clamping plate 204 according to the ship's curvature, the operator starts the servo motor 208 on the control panel 6. The output shaft of the servo motor 208 drives the rotating shaft 209 to rotate, causing the outer worm gear 210 to rotate accordingly. Since the worm wheel 206 meshes with the worm gear 210, the rotation of the worm gear 210 drives the worm wheel 206 to rotate. 06 This drives the rotating shaft 202 to rotate, which in turn causes the outer movable block 203 and the side clamp 204 to adjust their angles. Different ships have different side surface shapes and tilt angles. Through this angle adjustment function, the side clamp 204 can closely fit the curved surface of the ship, making the ship more stable on the support frame and providing a good foundation for welding operations. This reduces the errors caused by the ship's swaying during the welding process. The rubber pad 205 on one side of the side clamp 204 plays a role in buffering and increasing friction, effectively improving the support effect on the ship. During the angle adjustment of the side clamp 204, the rotating shaft 202 drives the indicator needle 213 to rotate. The operator can observe the scale line 212 corresponding to the indicator needle 213 to accurately understand the angle of adjustment of the side clamp 204, so as to perform precise operation.

[0018] Please see Figure 1-4As shown, a stepper motor 3 is installed on one side of the frame 1, and a bidirectional lead screw 301 is installed at the output end of the stepper motor 3. One end of the bidirectional lead screw 301 passes through the frame 1 and is rotatably installed inside one side of the frame 1. A guide rod 302 is fixed between the two sides of the frame 1. Both ends of the bidirectional lead screw 301 and the guide rod 302 are movably installed with a movable plate 303. Mounting plates 4 are installed on the top side of each movable plate 303. A drive motor 401 is installed on one side of each mounting plate 4. A bidirectional screw 402 is installed at the output end of the drive motor 401. Two sliding grooves 403 are symmetrically opened inside the top side of the mounting plate 4. Each set of sliding blocks 2 is slidably installed inside the sliding groove 403 in each movable plate 303. A screw hole is opened inside the bottom end of each sliding block 2. One end of the bidirectional screw 402 passes through the screw hole and is rotatably installed inside one side of the sliding groove 403. The frame 1 has several support shafts 5 rotatably mounted at equal intervals on its bottom side, and foot brake wheels 501 are mounted on the bottom side of the support shafts 5. In actual use, different types of ships have different lengths and widths. The existing technology is not convenient to adjust according to the length and width of the ship, which will reduce the support effect on the ship. When adjusting the distance between the movable plates 303 according to the length of the ship, the operator starts the stepper motor 3 on the control panel 6. The output shaft of the stepper motor 3 drives the bidirectional lead screw 301 to rotate. Since the bidirectional lead screw 301 is connected to the movable plate 303 by threads, and the guide rod 302 plays a guiding role, the movable plate 303 can only move along its axial direction, so that the two movable plates 303 can move to the middle or both sides at the same time. The distance between the two movable plates 303 can be flexibly adjusted according to the actual length of the ship, thereby achieving effective support for ships of different lengths. The vessel is placed on the top side of the movable plate 303. According to the width of the vessel, the operator starts the drive motor 401 on the control panel 6. The output shaft of the drive motor 401 drives the bidirectional screw 402 to rotate. Since the bidirectional screw 402 and the sliding block 2 are engaged through the screw hole, and the sliding block 2 slides in the slide groove 403, the slide groove 403 guides the sliding block 2, so that the two sliding blocks 2 on the same movable plate 303 can move to the middle or both sides at the same time, thereby effectively fixing vessels of different widths and ensuring that the vessel will not move laterally on the support frame. When the support frame needs to be moved, the operator releases the brake of the foot brake wheel 501. Since the foot brake wheel 501 is mounted on the support shaft 5, the support shaft 5 can rotate, allowing the support frame to be moved easily on the ground. This makes it convenient for the operator to move the support frame to a suitable working position according to actual needs. After reaching the working position, the operator operates the braking mechanism of the foot brake wheel 501 to brake it, thereby fixing the support frame on the ground and ensuring the stability of the support frame during shipbuilding operations.

[0019] Working principle: When the support frame needs to be moved, the operator releases the braking state of the foot brake wheel 501. Since the foot brake wheel 501 is mounted on the support shaft 5, the support shaft 5 can rotate, allowing the support frame to move easily on the ground. This makes it convenient for the operator to move the support frame to a suitable working position according to actual needs. After reaching the working position, the operator operates the braking mechanism of the foot brake wheel 501 to brake it, thereby fixing the support frame on the ground and ensuring the stability of the support frame during shipbuilding operations. When adjusting the distance between the movable plates 303 according to the length of the ship, the operator starts the stepper motor 3 on the control panel 6. The output shaft of the stepper motor 3 drives the bidirectional lead screw 301 to rotate. Since the bidirectional lead screw 301 is connected to the movable plate 303 by threads, and the guide rod 302 plays a guiding role, the movable plate 303 can only move along its axial direction, so that the two movable plates 303 can move to the middle or both sides at the same time. The distance between the two movable plates 303 can be flexibly adjusted according to the actual length of the ship, thereby achieving effective support for hulls of different lengths. The vessel is placed on the top side of the movable plate 303. According to the width of the vessel, the operator starts the drive motor 401 on the control panel 6. The output shaft of the drive motor 401 drives the bidirectional screw 402 to rotate. Since the bidirectional screw 402 and the sliding block 2 are engaged through the screw hole, and the sliding block 2 slides in the slide groove 403, the slide groove 403 guides the sliding block 2, so that the two sliding blocks 2 on the same movable plate 303 can move to the middle or both sides at the same time, thereby effectively fixing vessels of different widths and ensuring that the vessel will not move laterally on the support frame. When adjusting the angle of the side clamp 204 according to the curvature of the ship, the operator starts the servo motor 208 on the control panel 6. The output shaft of the servo motor 208 drives the rotating shaft 209 to rotate, causing the outer worm gear 210 to rotate accordingly. Since the worm wheel 206 meshes with the worm gear 210, the rotation of the worm gear 210 drives the worm wheel 206 to rotate, which in turn drives the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 causes the outer movable block 203 and the side clamp 204 to adjust their angles. Different ships have different side surface shapes and tilt angles, and this angle adjustment function allows for adjustments to be made. The side clamp 204 can closely fit the curved surface of the ship, making the ship more stable on the support frame and providing a good foundation for welding operations. It reduces the errors caused by the ship's swaying during the welding process. The rubber pad 205 on one side of the side clamp 204 plays a role in buffering and increasing friction, effectively improving the support effect on the ship. During the angle adjustment of the side clamp 204, the rotating shaft 202 drives the indicator needle 213 to rotate. The operator can observe the scale line 212 corresponding to the indicator needle 213 to accurately understand the angle of adjustment of the side clamp 204, so as to perform precise operation.
