Description

Technical Field

[0001] The present application relates to the technical field of ship propulsion, and in particular to an auxiliary installation device and installation process for a straight-wing propeller. Background Art

[0002] The straight-wing propeller has several vertical straight blades distributed in a ring. A single blade has a smooth transition from thick at the top to thin at the bottom, and a narrow shuttle-shaped cross-section. It is driven by a cylindrical box above to generate thrust and steering force, replacing various conventional propellers and rudders, and is suitable for ships that emphasize maneuverability.

[0003] At present, the installation of the straight-wing propeller is done by the operator lifting the straight-wing propeller onto the ship, dragging the straight-wing propeller to the top of the installation hole on the bottom of the ship, then lifting the rope from below, installing the straight-wing propeller into the installation hole, and then fixing it to complete the installation.

[0004] However, during the installation process, manual dragging and proofreading is required, which is time-consuming and labor-intensive, increases labor costs, and thus reduces installation efficiency. Summary of the invention

[0005] In order to improve the installation efficiency of straight-wing propellers, the present application provides an auxiliary installation device and an installation process for straight-wing propellers.

[0006] On the one hand, the present application provides an auxiliary installation device for a straight-wing propeller, which adopts the following technical solution:

[0007] An auxiliary installation device for a straight-wing propeller, comprising:

[0008] Rudder oar;

[0009] There are two rotating telescopic rods, which are respectively connected to the two sides of the installation through hole on the bottom of the ship. In the initial state, the two rotating telescopic rods are tilted in a direction away from each other, and a pressure spring is fixed in the rodless cavity of the rotating telescopic rod;

[0010] Two pressure plates are provided, the two pressure plates are respectively provided on the movable ends of the two rotating telescopic rods, and the two pressure plates are both in contact with the convex edges of the rudder propellers;

[0011] The adjusting components are provided with two groups, the two groups of the adjusting components correspond to the two rotating telescopic rods one by one, the two ends of the adjusting components are respectively connected to the hull and the rotating telescopic rod, and the adjusting components are used to adjust the opening angle between the two rotating telescopic rods;

[0012] There are two groups of retreat components, and the two groups of retreat components correspond to the two pressure plates respectively. The two ends of the retreat components are respectively connected to the pressure plates and the movable ends of the rotating telescopic rods. The retreat components are used to separate the pressure plates from the convex edges of the rudder propellers and to place the convex edges of the rudder propellers on the mounting through holes on the bottom of the ship.

[0013] By adopting the above technical solution, when the rudder propeller is transported to the top of the installation through hole of the hull by the lifting rope, the adjustment component detects that the rudder propeller is between the two rotating telescopic rods, and the adjustment component adjusts the opening angle between the two rotating telescopic rods to reduce the opening angle between the two rotating telescopic rods. The two rotating telescopic rods are rotated from an inclined state to a vertical state, and the rotating telescopic rod drives the pressure plate to rotate to below the convex edge of the rudder propeller, and the lifting rope is released to place the rudder propeller on the pressure plate.

[0014] Under the action of the steering propeller's own weight, the steering propeller squeezes the movable end of the rotating telescopic rod to shrink, the volume of the rodless cavity of the rotating telescopic rod decreases, the compression of the pressure spring increases, and the pressure plate drives the steering propeller to move to the installation through hole position. The top edge of the installation through hole squeezes the pressure plate. Under the action of the retreat component, the retreat component drives the pressure plate to move away from the installation through hole, so that the convex edge of the steering propeller abuts against the top edge of the installation through hole. At the same time, the pressure plate clamps the convex edge of the steering propeller, which increases the installation stability of the steering propeller, thereby improving the installation efficiency of the straight-wing propeller.

[0015] Optionally, the adjustment component includes:

[0016] An infrared sensor is arranged on the rotating telescopic rods and is located on a side where the two rotating telescopic rods are close to each other;

[0017] An electric telescopic rod, the fixed end of which is rotatably connected to the bottom of the boat, and the movable end of which is hinged to the rotating telescopic rod;

[0018] The infrared sensor is electrically connected to the electric telescopic rod through a controller, the infrared sensor is used to output a distance signal between the two rotating telescopic rods, and the controller responds to the distance signal output by the infrared sensor and controls the movable end of the electric telescopic rod to extend and retract.

[0019] By adopting the above technical solution, when the steering propeller is transported to the top of the installation through hole of the hull by the lifting rope, the infrared sensor detects the distance between the two rotating telescopic rods and outputs the distance signal between the two rotating telescopic rods to the controller. When the steering propeller is located between the two rotating telescopic rods, the distance between the two rotating telescopic rods changes, and the controller controls the active end of the electric telescopic rod to extend, and the active end of the electric telescopic rod pushes the rotating telescopic rod to rotate, and the rotating telescopic rod turns from an inclined state to a vertical state, so that the pressure plate rotates to the bottom of the steering propeller convex edge and receives the steering propeller. Through automatic adjustment, the need for manual intervention is reduced, thereby improving installation efficiency.

[0020] Optionally, one end of the pressure plate close to the mounting through hole is wedge-shaped, and the retreat component includes:

[0021] A support block is fixedly mounted on the movable end of the rotating telescopic rod, and a slide groove is provided on the support block;

[0022] A slider is slidably connected in the slide groove, and the sliding direction is the radial direction of the mounting through hole;

[0023] A return spring, both ends of which are respectively fixedly connected to the slider and the inner wall of the slide slot, and in an initial state, the return spring is in an extended state;

[0024] A support column has one end fixedly connected to the slider and the other end fixedly connected to the pressure plate.

[0025] By adopting the above technical solution, the pressure plate drives the rudder paddle to move to the installation through hole position, the top edge of the installation through hole squeezes the wedge-shaped side of the pressure plate, the pressure plate moves in the direction away from the installation through hole, the pressure plate drives the pillar to move, the pillar drives the slider to move, the compression amount of the return spring increases, so that the convex edge of the rudder paddle is easy to separate from the pressure plate, and abuts against the top edge of the installation through hole, so that the rudder paddle is convenient to be installed with the installation through hole;

[0026] Due to the friction force, the wedge-shaped side of the pressure plate presses against the convex edge of the steering propeller, and the pressure plate clamps the convex edge of the steering propeller, thereby improving the installation stability of the steering propeller.

[0027] Optionally, two pillars are provided, and the two pillars are arranged along the radial direction of the mounting through hole.

[0028] By adopting the above technical solution, through the support of two pillars, the pressure on the pressure plate can be more evenly distributed, which helps to reduce the shaking and deviation of the pressure plate, thereby improving the stability of the pressure plate.

[0029] Optionally, the wedge-shaped side of the pressure plate is rotatably connected with a ball.

[0030] By adopting the above technical solution, the top edge of the mounting hole squeezes the wedge-shaped side of the pressure plate. Since the rolling contact of the ball can significantly reduce the friction coefficient compared to the sliding contact, the friction between the pressure plate and the contact surface is reduced, making it easier for the pressure plate to retreat, thereby improving the installation efficiency.

[0031] Optionally, an installation component is also included, and the installation component includes:

[0032] There are two rotating plates, one end of the two rotating plates is hinged to each other, one end of the rotating plate close to the mounting through hole is arc-shaped, and the rotating telescopic rod and the electric telescopic rod are both rotatably connected to the rotating plate;

[0033] A fixed column, fixedly connected to one of the rotating plates;

[0034] A lock is rotatably connected to the other rotating plate and is lockably connected to the fixed column.

[0035] By adopting the above technical solution, during the initial installation, the rotating plate is rotated, the two rotating plates clamp the installation through holes, and then the lock buckle is rotated to buckle the lock buckle on the fixed column, thereby improving the stability of the installation.

[0036] Optionally, a plurality of the balls are provided, and the plurality of the balls are arranged along the circumference of the pressure plate.

[0037] By adopting the above technical solution and adding balls, the pressure plate is easier to move, thereby improving the installation efficiency.

[0038] Optionally, the ball bearing is made of steel.

[0039] By adopting the above technical solution, since the steel material has high strength and hardness and high wear resistance, the wear between the steel material and the contact surface can be reduced during the rolling process, thereby increasing the service life.

[0040] On the other hand, the present application provides an auxiliary installation process for a straight-wing propeller, which adopts the following technical solution:

[0041] An auxiliary installation process for a straight-wing propeller comprises the following steps:

[0042] S1 Lifting: Place the rudder propeller above the installation hole on the bottom of the ship;

[0043] S2 positioning: Start the electric telescopic rod and adjust the angles of the two rotating telescopic rods until they are adapted to the convex edge of the rudder propeller;

[0044] S3 installation: Use the pressure plate to push the convex edge of the rudder propeller into the installation hole on the bottom of the ship;

[0045] S4 reset: After installation is completed, retract the rotating telescopic rod to reset the rotating telescopic rod.

[0046] By adopting the above technical solution, the installation time is greatly shortened through the automatic adjustment of the electric telescopic rod and the rotating telescopic rod. Through the automatic operation, the dependence on manual operation is reduced, thereby reducing the installation cost.

[0047] Optionally, when the pressure plate contacts the convex edge of the rudder propeller, ensure that the ball rolls smoothly along the wedge-shaped side of the pressure plate.

[0048] By adopting the above technical solution, the smooth rolling of the ball along the wedge-shaped side ensures that the pressure plate can smoothly contact and push the convex edge of the rudder propeller into the installation through hole, thereby improving the accuracy and reliability of the installation.

[0049] In summary, the present application includes at least one of the following beneficial technical effects:

[0050] By setting up infrared sensors and electric telescopic rods, the pressure plate is rotated to the bottom of the convex edge of the steering propeller and receives the steering propeller, thereby reducing the need for manual intervention and improving installation efficiency.

[0051] By providing the support block, the slider, the return spring and the support column, the convex edge of the steering propeller can be easily separated from the pressure plate and abut against the top edge of the installation through hole, so that the steering propeller and the installation through hole can be easily installed;

[0052] By arranging the rotating plate, the fixing column and the locking buckle, the rotating telescopic rod and the electric telescopic rod are not prone to shaking, thereby improving the stability of the installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The two groups of retreat components 6 correspond to the two pressure plates 4 respectively, and the two ends of the retreat components 6 are respectively connected to the pressure plates 4 and the movable ends of the rotating telescopic rods 3. The retreat components 6 are used to separate the pressure plates 4 from the convex edges of the rudder propellers 1, and to place the convex edges of the rudder propellers 1 on the mounting through holes on the bottom of the ship.

[0064] When in use, the rudder propeller 1 is transported to the top of the installation through hole of the hull by the lifting rope, the lifting rope is lowered, and the rudder propeller 1 is sent between the two rotating telescopic rods 3, the adjustment component 5 reduces the opening angle between the two rotating telescopic rods 3, the rotating telescopic rods 3 drive the pressure plate 4 to rotate to the bottom of the convex edge of the rudder propeller 1, and the rudder propeller 1 is placed on the pressure plate 4;

[0065] Under the action of the steering propeller 1's own weight, the steering propeller 1 squeezes the movable end of the rotating telescopic rod 3 to shrink, and the pressure plate 4 drives the steering propeller 1 to move to the installation hole position. The top edge of the installation hole squeezes the pressure plate 4, and the retreat component 6 drives the pressure plate 4 to move away from the installation hole, so that the convex edge of the steering propeller 1 abuts against the top edge of the installation hole. At the same time, the pressure plate 4 clamps the convex edge of the steering propeller 1, which increases the installation stability of the steering propeller 1, thereby improving the installation efficiency of the straight-wing propeller.

[0066] Reference Figure 1 and Figure 2 The mounting assembly 2 includes a rotating plate 21, a fixed column 22 and a lock 23. Two rotating plates 21 are provided. One end of the two rotating plates 21 is hinged to each other. The rotating plate 21 is in the shape of an arc plate. When the two rotating plates 21 are closed, the inner side of the rotating plate 21 abuts against the mounting through hole, and the rotating telescopic rod 3 is hinged on the rotating plate 21.

[0067] Reference Figure 2 The fixed column 22 is in a circular column shape and is vertically arranged. The fixed column 22 is fixedly connected to one of the rotating plates 21 and is located at an end of the rotating plate 21 away from the hinge point. The lock 23 is rotatably connected to the other rotating plate 21. When the two rotating plates 21 are closed, the lock 23 is locked and connected to the fixed column 22.

[0068] Reference Figure 1 and Figure 3 In the initial state, the two rotating telescopic rods 3 are tilted in a direction away from each other, and a pressure spring 31 is fixed in the rodless cavity of the rotating telescopic rod 3.

[0069] When in use, during the initial installation, the rotating plate 21 is rotated, the two rotating plates 21 clamp the installation through holes, and then the lock buckle 23 is rotated to buckle the lock buckle 23 on the fixing column 22, thereby improving the stability of the installation.

[0070] Reference Figure 1 , Figure 3 and Figure 4 The adjusting assembly 5 includes an infrared sensor 51 and an electric telescopic rod 52. The infrared sensor 51 is arranged on the rotating telescopic rod 3 and is located on a side where the two rotating telescopic rods 3 are close to each other. The fixed end of the electric telescopic rod 52 is rotatably connected to the rotating plate 21, and the movable end is hinged to the rotating telescopic rod 3.

[0071] Reference Figure 3 and Figure 4 The infrared sensor 51 is electrically connected to the electric telescopic rod 52 through the controller. The infrared sensor 51 is used to output a distance signal between the two rotating telescopic rods 3. The controller responds to the distance signal output by the infrared sensor 51 and controls the movable end of the electric telescopic rod 52 to extend and retract.

[0072] During use, when the steering paddle 1 is transported to the top of the installation hole of the hull by the lifting rope, the infrared sensor 51 detects the distance between the two rotating telescopic rods 3, and outputs the distance signal between the two rotating telescopic rods 3 to the controller. The controller controls the active end of the electric telescopic rod 52 to extend, and the active end of the electric telescopic rod 52 pushes the rotating telescopic rod 3 to rotate. The rotating telescopic rod 3 is turned from an inclined state to a vertical state, so that the pressure plate 4 rotates to the bottom of the convex edge of the steering paddle 1 and receives the steering paddle 1. Through automatic adjustment, the need for manual intervention is reduced, thereby improving the installation efficiency.

[0073] Reference Figure 3 and Figure 4 The pressure plate 4 is in an arc-shaped plate shape, and one end close to the mounting through hole is wedge-shaped. The pressure plate 4 is arranged horizontally, and the inner concave part is arranged in the direction close to the convex edge of the steering propeller 1. The wedge-shaped side of the pressure plate 4 is rotatably connected with a plurality of balls 41, and the plurality of balls 41 are evenly arranged along the circumference of the pressure plate 4, and the balls 41 are made of steel material.

[0074] Reference Figure 1 , Figure 3 and Figure 4 The retreat assembly 6 includes a support block 61, a slider 62, a return spring 63 and a support column 64. The support block 61 is rectangular and fixedly mounted on the movable end of the rotating telescopic rod 3. The infrared sensor 51 is fixedly mounted on the support block 61. The two infrared sensors 51 are arranged in a direction close to each other. A slide groove 611 is provided on the support block 61. The slider 62 is slidably connected in the slide groove 611, and the sliding direction is the radial direction of the mounting through hole.

[0075] Reference Figure 4 The two ends of the return spring 63 are respectively fixedly connected to the slider 62 and the inner wall of the slide groove 611. In the initial state, the return spring 63 is in an extended state. Two pillars 64 are provided, and the two pillars 64 are arranged along the radial direction of the installation through hole. One end of the pillar 64 is fixedly connected to the slider 62, and the other end is fixedly connected to the pressure plate 4.

[0076] When in use, the pressure plate 4 drives the steering paddle 1 to move to the installation hole position, and the top edge of the installation hole squeezes the ball 41 on the wedge-shaped side of the pressure plate 4. Under the rolling action of the ball 41, the pressure plate 4 moves away from the installation hole, and the pressure plate 4 drives the support 64 to move, and the support 64 drives the slider 62 to move, so that the convex edge of the steering paddle 1 is easy to detach from the pressure plate 4 and abut against the top edge of the installation hole, thereby facilitating the installation of the steering paddle 1 and the installation hole.

[0077] The implementation principle of the auxiliary installation device of the straight-wing propeller of the embodiment of the present application is as follows: first, during the initial installation, the rotating plate 21 is rotated, the two rotating plates 21 clamp the installation through holes, and then the lock buckle 23 is rotated to buckle the lock buckle 23 on the fixing column 22;

The infrared sensor 51 detects the distance between the two rotating telescopic rods 3 and outputs the distance signal between the two rotating telescopic rods 3 to the controller. The controller controls the active end of the electric telescopic rod 52 to extend. The active end of the electric telescopic rod 52 pushes the rotating telescopic rod 3 to rotate. The rotating telescopic rod 3 rotates from an inclined state to a vertical state, so that the pressure plate 4 rotates to the lower side of the convex edge of the steering paddle 1 and receives the steering paddle 1.

[0079] Under the deadweight of the steering paddle 1, the steering paddle 1 squeezes the movable end of the rotating telescopic rod 3 to shrink, the pressure spring 31 accumulates elastic force, the pressure plate 4 drives the steering paddle 1 to move to the installation through hole position, and the top edge of the installation through hole squeezes the ball 41 on the wedge-shaped side of the pressure plate 4. Under the rolling action of the ball 41, the pressure plate 4 moves away from the installation through hole, the pressure plate 4 drives the support 64 to move, and the support 64 drives the slider 62 to move. The return spring 63 accumulates elastic force, so that the convex edge of the steering paddle 1 is easy to separate from the pressure plate 4 and abut against the top edge of the installation through hole, so as to facilitate the installation of the steering paddle 1 and the installation through hole;

[0080] At the same time, the pressure plate 4 clamps the convex edge of the rudder propeller 1, which increases the installation stability of the rudder propeller 1, thereby improving the installation efficiency of the straight-wing propeller.
