[0001] The invention relates to the field of supporting devices, in particular to a temporary supporting device for pre-embedded ship rudder stocks. Background Art

[0002] Ship is a general term for various vessels. Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements.

[0003] Ships are man-made vehicles that mainly operate in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials.

[0004] During the ship construction process, the rudder stock cannot be installed in place due to the delay in the delivery of the steering gear. In order not to affect the production progress and ensure that the main section is loaded as planned, the rudder stock needs to be placed in the engine room main section in advance. When the prefabricated rudder stock is placed, the rudder stock needs to be fixed and limited to stabilize the prefabricated rudder stock and prevent the prefabricated rudder stock from tilting. However, the current fixed limiting device cannot conveniently adjust the size of the connection port, and therefore cannot adapt to prefabricated rudder stocks of different diameters. For this reason, a temporary support device is needed for pre-embedded ship rudder stocks to facilitate the limiting of the prefabricated rudder stock. Summary of the invention

[0005] The invention aims to overcome the defect that it is inconvenient to adjust the size of the limit opening and to provide a temporary supporting device for pre-embedded ship rudder stock.

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

[0007] Preferably, the clamping mechanism includes an external fixed block, a guide rod, a cross bar, a driving rod, a clamping plate and an internal fixed block. The top of the top frame is connected to two groups of two symmetrically distributed external fixed blocks, the side walls of the two external fixed blocks are connected to the guide rod, the top of the top frame is connected to two symmetrically distributed internal fixed blocks, the side walls of the guide rod are slidably connected to the clamping plate, the top of the top frame is connected to the cross bar, the cross bar is located between the two external fixed blocks, the side wall of the driving rod is threadedly connected to the cross bar, and one end of the driving rod is rotatably connected to one of the clamping plates.

[0008] Preferably, the two clamping plates are respectively located on both sides of the inner fixing block, the side wall of the guide rod passes through 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 comprises 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 is meshed with the gear.

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

[0011] Preferably, the positioning mechanism comprises a circular shaft, a rotating plate and a positioning through hole, the top end of the other clamping plate is connected to two symmetrically distributed circular shafts, the side wall of the circular shaft is connected to the rotating plate, and the upper end of the rotating plate is provided with a positioning through hole.

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

[0013] Preferably, the limiting mechanism includes a connecting plate, a positioning rod, a round rod, a pressure plate, a screw and a swivel, 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 slidingly connected to the pressure plate, the side wall of the pressure plate is rotatably connected to the swivel, the top end of the swivel 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 the present invention are:

[0015] 1) Place the prefabricated rudder stock between the two clamping plates, rotate the driving rod, and drive one of the clamping plates to move along the guide rod. Use the driving mechanism to drive the other clamping plate to move, so that the two clamping plates are close to each other, thereby clamping the two sides of the prefabricated rudder stock to prevent 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 splints drives one of the racks to move, one of the racks drives the gear to rotate, and the gear drives the other rack to move in the opposite direction, so that the other rack drives the other splint to move in the opposite direction, achieving the effect of the two splints moving closer or farther away, and also achieving the effect of adjustable spacing between the two splints.

[0017] 3) After the clamping mechanism clamps two sides of the prefabricated rudder stock, rotate the rotating plate to make the rotating plate clamp the other two sides of the prefabricated rudder stock, and insert the positioning rod into the positioning through hole. At this time, the pressure plate is located below the bottom end of one of the clamping plates, so that the positioning rod is abutted against the top end of one of the clamping plates, and the screw is rotated. The screw drives the swivel to rotate and drives the swivel to move upward, so that the swivel pulls the pressure plate upward, and the pressure plate moves upward along the round rod and abuts against the bottom end 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 and the top end of one of the clamping plates clamp the rotating plate, thereby fixing the rotating plate, and the two rotating plates can limit the other two sides of the prefabricated rudder stock, thereby achieving an adjustable limiting effect. At the same time, the inclination of the prefabricated rudder stock can also be limited from the prefabricated rudder stock. BRIEF DESCRIPTION OF THE DRAWINGS

The screw rod 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 pressing plate upward. Plate 604 and pressure plate 604 move upward along round rod 603 and abut against the bottom end of one of the clamping plates 305, so that the positioning rod 602 and pressure plate 604 clamp one of the clamping plates 305. At the same time, the connecting plate 601 and the top end of one of the clamping plates 305 clamp the rotating plate 502, thereby fixing the rotating plate 502.
