Description

Technical Field

[0001] This invention relates to the field of support devices, and in particular to temporary support devices for pre-embedding ship rudder stock. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations, and vary in technical performance, equipment, and structural type according to different usage requirements.

[0003] A ship is a man-made means of transportation that primarily operates in water. Civilian vessels are generally called ships, military vessels are called warships, and small boats are called boats or dinghies; collectively, they are referred to as ships or naval vessels. Internally, they mainly include interior space, supporting structures, and drainage structures, and possess a propulsion system that utilizes external or internal energy sources. Their external shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials.

[0004] During shipbuilding, delays in the delivery of the steering gear can prevent the rudder stock from being installed properly. To avoid impacting production schedules and ensure the assembly of the main section as planned, the rudder stock needs to be pre-placed in the engine room section. When placing the prefabricated rudder stock, it is necessary to fix and limit its position to stabilize it and prevent it from tilting. However, current fixing and limiting devices cannot easily adjust the size of the connection port, thus they cannot accommodate prefabricated rudder stocks of different diameters. Therefore, a temporary support device for the ship's rudder stock needs to be pre-embedded to facilitate the positioning of the prefabricated rudder stock. Summary of the Invention

[0005] The purpose of this invention is to provide a temporary support device for pre-embedding ship rudder stock, which overcomes the drawback of inconvenient adjustment of the size of the limiting opening.

[0006] The technical solution to achieve the above objective is: a temporary support device for pre-embedded ship rudder stock, including a support rod, a top frame connected to the top of the support rod, a clamping mechanism provided on the top frame, a driving mechanism installed on the clamping mechanism, a positioning mechanism installed on the clamping mechanism, and a limit mechanism installed on the positioning mechanism and the clamping mechanism.

[0007] Preferably, the clamping mechanism includes an outer fixed block, a guide rod, a crossbar, a drive rod, a clamping plate, and an inner fixed block. The top of the top frame is connected to two sets of symmetrically distributed outer fixed blocks, and the side walls of the two outer fixed blocks are connected to guide rods. The top of the top frame is connected to two symmetrically distributed inner fixed blocks. The side walls of the guide rods are slidably connected to clamping plates. The top of the top frame is connected to a crossbar, which is located between the two outer fixed blocks. The side wall of the drive rod is threadedly connected to the crossbar, and one end of the drive rod is rotatably connected to one of the clamping plates.

[0008] Preferably, the two clamping plates are located on both sides of the inner fixing block, the side wall of the guide rod penetrates the inner fixing block, and the inner fixing block is located in the middle between the two outer fixing blocks.

[0009] Preferably, the driving mechanism includes a rack, a rotating shaft, and a gear. The top end of the inner fixed block is rotatably connected to the rotating shaft, the top end of the rotating shaft is connected to the gear, the top end of the clamping plate is connected to the rack, and the side wall of the rack meshes with the gear.

[0010] Preferably, the two racks are staggered with respect to the gear.

[0011] Preferably, the positioning mechanism includes a round shaft, a rotating plate, and a positioning through hole. The top of another clamping plate is connected to two symmetrically distributed round shafts. The sidewalls of the round shafts are connected to the rotating plate, and the upper end of the rotating plate is provided with a positioning through hole.

[0012] Preferably, the sidewall of the rotating plate is connected to a friction pad.

[0013] Preferably, the limiting mechanism includes a connecting plate, a positioning rod, a round rod, a pressure plate, a screw, and a rotating ring. The bottom end of the connecting plate is connected to the positioning rod, the side wall of the connecting plate is connected to the round rod, the side wall of the round rod is slidably connected to the pressure plate, the side wall of the pressure plate is rotatably connected to the rotating ring, the top end of the rotating ring is rotatably connected to the screw, and the side wall of the screw is threadedly connected to the connecting plate.

[0014] The beneficial effects of this invention are:

[0015] 1) Place the prefabricated rudder stock between the two clamping plates, rotate the drive rod, and the drive rod will drive one of the clamping plates to move along the guide rod. Using the drive mechanism, the other clamping plate will move, so that the two clamping plates are close to each other, thereby clamping the two sides of the prefabricated rudder stock and preventing the prefabricated rudder stock from tilting. The adjustable effect of the two clamping plates can be used to clamp prefabricated rudder stocks of different diameters.

[0016] 2) One of the clamps drives one of the racks to move, one of the racks drives the gear to rotate, the gear drives the other rack to move in the opposite direction, thereby causing the other rack to drive the other clamp to move in the opposite direction, achieving the effect of the two clamps moving closer or further apart, thus achieving the effect of adjustable spacing between the two clamps.

[0017] 3) After the clamping mechanism clamps one side of the prefabricated rudder post, rotate the rotating plate to clamp the other two sides of the prefabricated rudder post and insert the positioning rod into the positioning through hole. At this time, the pressure plate is located below the bottom of one of the clamping plates, so that the positioning rod abuts against the top of one of the clamping plates. Rotate the screw, and the screw drives the rotating ring to rotate and move the rotating ring upward, so that the rotating ring pulls the pressure plate upward. The pressure plate moves upward along the round rod and abuts against the bottom of one of the clamping plates, so that the positioning rod and the pressure plate clamp one of the clamping plates. At the same time, the connecting plate clamps the rotating plate with the top of one of the clamping plates, thereby fixing the rotating plate. The two rotating plates can restrict the other two sides of the prefabricated rudder post, thereby achieving an adjustable limiting effect. At the same time, the tilt of the prefabricated rudder post can also be restricted from the prefabricated rudder post. Attached Figure Description

[0031] Reference Appendix Figure 1-9 A temporary support device for pre-embedded ship rudder stock includes a support rod 1, a top frame 2 connected to the top of the support rod 1, the top frame 2 being U-shaped, a clamping mechanism 3 being provided on the top frame 2, a drive mechanism 4 being installed on the clamping mechanism 3, a positioning mechanism 5 being installed on the clamping mechanism 3, and a limit mechanism 6 being installed on the positioning mechanism 5 and the clamping mechanism 3.

[0032] Reference Appendix Figure 1-5 The clamping mechanism 3 includes an outer fixed block 301, a guide rod 302, a crossbar 303, a drive rod 304, a clamping plate 305, and an inner fixed block 306. The top of the top frame 2 is connected to two sets of symmetrically distributed outer fixed blocks 301. The side walls of the two outer fixed blocks 301 are connected to the guide rod 302. The top of the top frame 2 is connected to two symmetrically distributed inner fixed blocks 306. The side walls of the guide rod 302 are slidably connected to the clamping plate 305. The top of the top frame 2 is connected to the crossbar 303, which is located between the two outer fixed blocks 301. The side wall of the drive rod 304 is threadedly connected to the crossbar 303. One end of the drive rod 304 is rotatably connected to one of the clamping plates 305. The two clamping plates 305 are located on both sides of the inner fixed block 306. The side wall of the guide rod 302 passes through the inner fixed block 306, which is located in the middle between the two outer fixed blocks 301.

[0033] The prefabricated rudder stock is placed between two clamping plates 305. The drive rod 304 is rotated, and the drive rod 304 drives one of the clamping plates 305 to move along the guide rod 302. The drive mechanism 4 drives the other clamping plate 305 to move, so that the two clamping plates 305 move closer to each other, thereby clamping the two sides of the prefabricated rudder stock and preventing the prefabricated rudder stock from tilting. The adjustable effect of the two clamping plates 305 can be used to clamp prefabricated rudder stocks of different diameters.

[0034] Reference Appendix Figure 4-7 The drive mechanism 4 includes a rack 401, a rotating shaft 402, and a gear 403. The top end of the inner fixed block 306 is rotatably connected to the rotating shaft 402, the top end of the rotating shaft 402 is connected to the gear 403, the top end of the clamping plate 305 is connected to the rack 401, the side wall of the rack 401 meshes with the gear 403, and the two racks 401 are staggered about the gear 403.

[0035] One of the clamping plates 305 drives one of the racks 401 to move, one of the racks 401 drives the gear 403 to rotate, and the gear 403 drives the other rack 401 to move in the opposite direction, thereby causing the other rack 401 to drive the other clamping plate 305 to move in the opposite direction, so as to achieve the effect of the two clamping plates 305 moving closer or further apart, thus achieving the effect of adjustable spacing between the two clamping plates 305.

[0036] Reference Appendix Figure 3-9 The positioning mechanism 5 includes a round shaft 501, a rotating plate 502, and a positioning through hole 503. The top of another clamping plate 305 is connected to two symmetrically distributed round shafts 501. The side wall of the round shaft 501 is connected to the rotating plate 502. The upper end of the rotating plate 502 is provided with a positioning through hole 503. The side wall of the rotating plate 502 is connected to a friction pad 7. The limiting mechanism 6 includes a connecting plate 601, a positioning rod 602, a round rod 603, a pressure plate 604, a screw 605, and a rotating ring 606. The bottom end of the connecting plate 601 is connected to the positioning rod 602. The side wall of the connecting plate 601 is connected to the round rod 603. The side wall of the round rod 603 is slidably connected to the pressure plate 604. The side wall of the pressure plate 604 is rotatably connected to the rotating ring 606. The top end of the rotating ring 606 is rotatably connected to the screw 605. The side wall of the screw 605 is threadedly connected to the connecting plate 601.

[0037] After the clamping mechanism 3 clamps one side of the prefabricated rudder post, the rotating plate 502 is rotated to clamp the other two sides of the prefabricated rudder post, and the positioning rod 602 is inserted into the positioning through hole 503. At this time, the pressure plate 604 is located below the bottom of one of the clamping plates 305, so that the positioning rod 602 abuts against the top of one of the clamping plates 305. The screw 605 is rotated, and the screw 605 drives the rotating ring 606 to rotate, and drives the rotating ring 606 to move upward, so that the rotating ring 606 pulls the pressure plate upward. Plate 604 and pressure plate 604 move upward along the round rod 603 and abut against the bottom end of one of the clamping plates 305, so that positioning rod 602 and pressure plate 604 clamp one of the clamping plates 305. At the same time, connecting plate 601 clamps the top of one of the clamping plates 305 with rotating plate 502, thereby fixing rotating plate 502. The two rotating plates 502 can restrict the other two sides of the prefabricated rudder, thereby achieving an adjustable limiting effect. At the same time, the tilt of the prefabricated rudder can also be restricted from the prefabricated rudder.

[0038] Working principle: The prefabricated rudder stock is placed between two clamping plates 305. The drive rod 304 is rotated, which drives one of the clamping plates 305 to move along the guide rod 302. One of the clamping plates 305 drives one of the racks 401 to move. One of the racks 401 drives the gear 403 to rotate. The gear 403 drives the other rack 401 to move in the opposite direction, which in turn drives the other clamping plate 305 to move in the opposite direction. This achieves the effect of bringing the two clamping plates 305 closer or further apart, thus achieving the effect of adjustable spacing between the two clamping plates 305. This also drives the other clamping plate 305 to move, bringing the two clamping plates 305 closer together, thereby clamping both sides of the prefabricated rudder stock and preventing it from tilting. The adjustable effect of the two clamping plates 305 can be used to clamp prefabricated rudder stocks of different diameters.

[0039] After the clamping mechanism 3 clamps one side of the prefabricated rudder post, the rotating plate 502 is rotated to clamp the other two sides of the prefabricated rudder post, and the positioning rod 602 is inserted into the positioning through hole 503. At this time, the pressure plate 604 is located below the bottom of one of the clamping plates 305, so that the positioning rod 602 abuts against the top of one of the clamping plates 305. The screw 605 is rotated, and the screw 605 drives the rotating ring 606 to rotate, and drives the rotating ring 606 to move upward, so that the rotating ring 606 pulls the pressure plate upward. Plate 604 and pressure plate 604 move upward along the round rod 603 and abut against the bottom end of one of the clamping plates 305, so that positioning rod 602 and pressure plate 604 clamp one of the clamping plates 305. At the same time, connecting plate 601 clamps the top of one of the clamping plates 305 with rotating plate 502, thereby fixing rotating plate 502. The two rotating plates 502 can restrict the other two sides of the prefabricated rudder, thereby achieving an adjustable limiting effect. At the same time, the tilt of the prefabricated rudder can also be restricted from the prefabricated rudder.
