Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for foremast manufacturing, specifically a ground-mounted frame for foremast manufacturing. Background Technology

[0002] Traditional sailboats typically use wooden foremasts, while modern sailboats widely employ materials such as aluminum alloy and carbon fiber. Aluminum alloy offers a balance of strength and durability, while carbon fiber is lighter and stronger, increasing the ship's righting moment, reducing heeling during sailing, and resulting in faster and more comfortable sailing. The foremast is the mast closest to the bow of a sailboat, occupying a forward position in the overall layout, and is an important component of the sailboat's mast system.

[0003] The original manufacturing process for the foremast involved on-site fabrication. However, during the later stages of production, the foremast needed to be flipped over and mounted on a scaffold. This mounting process involved erecting and dismantling scaffolding and working at heights. Furthermore, flipping the foremast required utilizing flatbed trucks and frame resources within the factory, and the flipping process damaged the surface paint, necessitating subsequent paint repair. This resulted in a waste of labor and time. Therefore, a ground-mounted scaffold for foremast fabrication was proposed. Utility Model Content

A knob is fixedly connected to the outer surface of the positive and negative lead screw, and two threaded plates are respectively threaded to the outer surface of the positive and negative lead screw.

[0008] As a further explanation of this utility model, a first spring is fixedly connected to the bottom inner surface of the cavity, and the top of the first spring is fixedly connected to the bottom of the movable plate.

Detailed Implementation

[0025] 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 protection scope of the present utility model.

[0026] Example 1:

[0027] Please refer to the following: Figures 1-6This utility model provides a technical solution: a ground-mounted frame for manufacturing a foremast, comprising a base plate 1 and two connecting plates 2. The outer surface of the base plate 1 is hollow. Support plates 3 are fixedly connected to the top outer surfaces of the two connecting plates 2. An arc-shaped opening 6 is formed on the outer surface of the support plate 3. A movable plate 4 is movably inserted into the outer surface of the support plate 3. A support block 5 is fixedly connected to the top outer surface of the movable plate 4. Receiving grooves 18 are formed on the left and right outer surfaces of the support plate 3. A rotating shaft is fixedly connected inside the receiving groove 18. A support rod 15 is rotatably sleeved on the outer surface of the rotating shaft. The end of the support rod 15 located outside the support plate 3 rotates. The device is connected to a stabilizing plate 16. Specifically, the device is fixed at the manufacturing site. During manufacturing, the foremast is hoisted onto the support plate 3, ensuring that the arc size of the foremast corresponds to the arc opening 6. The foremast is then welded and manufactured. After manufacturing, it is painted directly. This allows for direct operation on the jig. Once the foremast is manufactured on the jig, it does not need to be turned over or transported to the jig by flatbed truck, reducing the waste of flatbed truck and frame resources in the factory. Without the need for jig, the dismantling and erection of scaffolding is reduced or eliminated, reducing the waste of labor costs. The jig is ground-mounted, eliminating the need for high-altitude operations and reducing safety hazards. The absence of the need for turning over also reduces damage to the paint.

[0028] In this embodiment, the support plate 3 has a cavity inside. Inside the cavity, a first support shaft and a second support shaft are rotatably connected to both sides of the movable plate 4. A first gear 12 is fixedly sleeved on the outer surface of the first support shaft, and a second gear 13 is fixedly sleeved on the outer surface of the second support shaft. The outer surfaces of the first gear 12 and the second gear 13 are movably meshed. Several teeth 11 are fixedly connected to the outer surfaces of both sides of the movable plate 4. The teeth 11 mesh with the two first gears 12 respectively. Specifically, when the foremast is hoisted onto the support plate 3, as the foremast rests on the support plate 3, it contacts the support block 5. The support block 5 drives the movable plate 4 to move downward, causing the teeth 11 to move downward. The teeth 11 mesh with the first gear 12, causing the first gear 12 to rotate. When the first gear 12 rotates, it drives the second gear 13 to rotate. The second gear 13 drives the second support shaft to rotate, thereby driving the support rod 15 to rotate, causing the stabilizing plate 16 to move downward until the stabilizing plate 16 contacts the ground, increasing the stability of the device.

[0029] In this embodiment, a first spring 14 is fixedly connected to the bottom inner surface of the cavity. The top of the first spring 14 is fixedly connected to the bottom of the movable plate 4. Specifically, the elastic force of the first spring 14 is greater than the weight of the movable plate 4 and the support block 5, so that when the support block 5 is not under force, the first spring 14 can drive the movable plate 4 and the support block 5 to reset.

[0030] In this embodiment, a second spring 17 is rotatably connected to the outer surface of the support rod 15, and the other end of the second spring 17 is rotatably connected to the interior of the cavity. Specifically, when the support rod 15 moves, the second spring 17 deforms, and when the support rod 15 is not under force, the second spring 17 drives the support rod 15 to return to its original position.

[0031] In this embodiment, an arc-shaped pad 7 is installed on the outer surface of the support plate 3 at the arc-shaped opening 6. The arc-shaped pad 7 is connected to the support plate 3 by bolts. Specifically, the arc-shaped pad 7 protects the surface of the support plate 3, reducing the possibility of the support plate 3 scraping the paint off the surface of the mast. The arc-shaped pad 7 can be easily replaced by unscrewing the bolts.

[0032] In this embodiment, after the support block 5 moves to a position flush with the arc-shaped pad 7, the stabilizing plate 16 contacts the ground.

[0033] In this embodiment, a slide rod is fixedly connected inside the cavity, a movable plate 4 is movably sleeved on the outside of the slide rod, and a first spring 14 is sleeved on the outside of the slide rod. Specifically, the movable plate 4 slides outside the slide rod when it moves, and the slide rod guides the movable plate 4 and prevents the first spring 14 from tilting.

[0034] In this embodiment, a guide rod is fixedly connected between the two fixed blocks 10, and the connecting plate 2 is movably sleeved on the outer surface of the guide rod. Specifically, when the positive and negative screws 8 rotate and drive the connecting plate 2 to move, the connecting plate 2 slides on the surface of the guide rod, so that the connecting plate 2 moves stably and avoids the connecting plate 2 from rotating with the rotation of the positive and negative screws 8.

[0035] In the specific implementation process, the device is fixed at the manufacturing site. During manufacturing, the foremast is hoisted onto the support plate 3, ensuring that the arc size of the foremast corresponds to the arc opening 6. The foremast is then welded together, and after completion, it is painted directly. This allows for direct operation on the jig. Once the foremast is manufactured on the jig, there is no need to turn it over or transport it to the jig on a flatbed truck, reducing the waste of flatbed truck and frame resources in the factory. Eliminating the need for scaffolding removal and assembly will reduce or eliminate the need for scaffolding dismantling and assembly, thus reducing labor costs. The jig fixture is ground-based, eliminating the need for high-altitude operations and reducing safety risks. Potential hazards: To reduce damage to the paint without needing to flip it over, when the foremast is hoisted onto the support plate 3, as the foremast rests on the support plate 3, it contacts the support block 5. The support block 5 drives the movable plate 4 to move downward, causing the gear 11 to move downward. The gear 11 meshes with the first gear 12, causing the first gear 12 to rotate. When the first gear 12 rotates, it drives the second gear 13 to rotate. The second gear 13 drives the second support shaft to rotate, thereby driving the support rod 15 to rotate, causing the stabilizing plate 16 to move downward until the stabilizing plate 16 contacts the ground, increasing the stability of the device.

[0036] Example 2:

[0037] Please refer to the following: Figures 1-6 This utility model provides a technical solution: two fixed blocks 10 arranged symmetrically on the top outer surface of the base plate 1 are fixedly connected, and a positive and negative screw rod 8 is rotatably connected between the two fixed blocks 10. A knob 9 is fixedly connected to the outer surface of the positive and negative screw rod 8, and two threaded plates are respectively threaded to the outer surface of the positive and negative screw rod 8. Specifically, rotating the knob 9 causes the positive and negative screw rod 8 to rotate, and the positive and negative screw rod 8 causes the two connecting plates 2 to move.

[0038] In this embodiment, multiple movable wheels 19 are installed on the bottom outer surface of the connecting plate 2. The bottom of the movable wheels 19 is flush with the bottom of the base plate 1. Specifically, when the position of the connecting plate 2 is adjusted by rotating the positive and negative lead screws 8, the movable wheels 19 move on the ground and distribute the force on the positive and negative lead screws 8 to the left and right, so as to avoid deformation of the positive and negative lead screws 8 due to long-term gravity pressure.

[0039] In this embodiment, a guide rod is fixedly connected between the two fixed blocks 10, and the connecting plate 2 is movably sleeved on the outer surface of the guide rod. Specifically, when the positive and negative screws 8 rotate and drive the connecting plate 2 to move, the connecting plate 2 slides on the surface of the guide rod, so that the connecting plate 2 moves stably and avoids the connecting plate 2 from rotating with the rotation of the positive and negative screws 8.

[0040] In the specific implementation process, according to actual needs, before processing, turn knob 9. Knob 9 drives the positive and negative lead screws 8 to rotate. The positive and negative lead screws 8 drive the connecting plate 2 to move, so that the connecting plate 2 moves closer to each other, thereby adjusting the distance between the two support plates 3. This allows for the support of masts of different sizes as needed, improving the support effect.

[0041] Working Principle: In use, this device is fixed at the manufacturing site. During manufacturing, the foremast is hoisted onto the support plate 3, ensuring the arc dimensions of the foremast correspond to the arc opening 6. The foremast is then welded together. After manufacturing, it is painted directly. This allows for direct operation on the jig. Since the foremast is manufactured on the jig, it does not require turning over or transporting it to the frame on a flatbed truck, reducing waste of flatbed truck and frame resources in the factory. Eliminating the need for scaffolding removal and assembly reduces or eliminates the need for scaffolding dismantling and assembly, thus reducing labor costs. The jig is floor-mounted, eliminating the need for high-altitude work, reducing... Fewer safety hazards; less damage to paint after turning over; when the foremast is hoisted onto the support plate 3, as the foremast rests on the support plate 3, it contacts the support block 5. The support block 5 drives the movable plate 4 to move downward, causing the teeth 11 to move downward. The teeth 11 mesh with the first gear 12, causing the first gear 12 to rotate. When the first gear 12 rotates, it drives the second gear 13 to rotate. The second gear 13 drives the second support shaft to rotate, thereby driving the support rod 15 to rotate, causing the stabilizing plate 16 to move downward until the stabilizing plate 16 contacts the ground, increasing the stability of the device.

[0042] Before processing, according to actual needs, turn knob 9. Knob 9 drives the positive and negative lead screws 8 to rotate. The positive and negative lead screws 8 drive the connecting plate 2 to move, so that the connecting plate 2 moves closer to each other, thereby adjusting the distance between the two support plates 3. This allows for the support of masts of different sizes as needed, improving the support effect.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
