Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to an auxiliary tooling for propeller installation and a method for propeller installation. Background Technology

[0002] Straight-blade propellers are a new type of ship propulsion that has emerged in recent years. Several blades located underwater are vertically mounted on a rotating disk and can rotate 360° around the center line of the disk. While the blades revolve around the center line of the disk, they can also rotate at a constant speed around their own axis under the drive of an electric motor. When water flows over the surface of the blades, it exerts a force on the rotating blades, thereby enabling the ship to perform special driving operations such as turning in place, moving laterally, rapidly reversing, and steering within a very low speed range.

[0003] Straight-blade propellers are mostly installed by hoisting, and the installation process has high requirements for angle and position. However, existing straight-blade propellers are generally large in size and heavy in weight, which makes the hoisting and installation process quite inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary tooling and method for blade installation, which can improve the accuracy and efficiency of blade installation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Auxiliary tooling for blade installation includes:

[0007] Fixing plate;

[0008] A locking assembly is disposed on the fixed plate and is used to apply a force to the blade to press the blade against the fixed plate.

[0009] A support shaft, wherein the fixing plate is rotatably mounted on the support shaft about the axis of the support shaft;

[0010] Mounting bracket, wherein a horizontal axis perpendicular to the support shaft is provided on the mounting bracket, and the support shaft is rotatably mounted on the horizontal axis;

[0011] A rotation adjustment assembly includes a first connector disposed on the mounting bracket and a second connector disposed on the support shaft. The distance between the first connector and the second connector can be shortened or lengthened to allow the support shaft to rotate on the mounting bracket about the axis of the transverse axis.

[0012] Preferably, the fixing plate is provided with inserts at both ends of the support shaft, and the two ends of the support shaft are respectively inserted into the inserts, with the support shaft and the inner wall of the inserts having a clearance fit.

[0013] Preferably, the fixing plate is provided with a locking member, which can apply a force to the support shaft so that the side of the support shaft abuts against the inner wall of the insert.

[0014] Preferably, the locking member is threaded to the side wall of the insert, and the end of the locking member extending out of the side wall of the insert abuts against the support shaft.

[0015] Preferably, the rotation adjustment assembly further includes an adjustment sleeve, the two ends of which are threadedly connected to the first connector and the second connector, respectively.

[0016] Rotating the adjusting sleeve in the forward direction brings the first connector and the second connector closer together, while rotating the adjusting sleeve in the reverse direction moves the first connector and the second connector further apart.

[0017] Preferably, the locking assembly includes a screw, a pressure plate, and a pressing bolt. The screw is disposed on the fixed plate, the pressure plate passes through the screw, and the pressing bolt is screwed onto the screw and abuts against the pressure plate.

[0018] The pressure bolt can apply force to the pressure plate so that the pressure plate abuts against the blade.

[0019] Preferably, the fixing plate includes a back plate and a bottom plate connected to each other, the bottom plate is used to support the blade, the back plate is used to abut against the blade, and the screw is disposed on the back plate.

[0020] Preferably, the blade installation auxiliary tooling further includes an installation base, the installation frame is disposed on the installation base, and a plurality of pads are evenly spaced on the side of the installation base facing away from the installation frame.

[0021] Preferably, the mounting bracket includes an upright beam and a diagonal brace. The upright beam is mounted on the mounting base, the horizontal axis is mounted on the upright beam, one end of the diagonal brace is fixed to the mounting base, and the other end of the diagonal brace is fixed to the upright beam.

[0022] The blade installation method, using the aforementioned blade installation auxiliary fixture, includes the following steps:

[0023] S1. Place the blade on the fixed plate and use the locking assembly to lock the blade on the fixed plate;

[0024] S2. Adjust the distance between the first connector and the second connector so that the fixing plate drives the blade to rotate around the horizontal axis to a suitable vertical angle for installation.

[0025] S3. Horizontally rotate the fixed plate so that the blades on the fixed plate rotate about the axis of the support shaft to a suitable horizontal angle for installation.

[0026] S4. Use a forklift to lift the mounting frame to the designated installation position and install the blade.

[0027] The beneficial effects of this invention are as follows:

[0028] The blade installation auxiliary fixture provided by this invention has a fixing plate for abutting against the blade. Since the fixing plate is equipped with a locking component that applies force to the blade to press it firmly against the fixing plate, the locking component can securely fix the blade to the fixing plate, ensuring the stability of subsequent blade installation. A support shaft is rotatably mounted on the horizontal axis of the mounting frame. The first and second connectors of the rotation adjustment component are respectively mounted on the mounting frame and the support shaft. Since the distance between the first and second connectors can be shortened or lengthened, the rotation adjustment component can adjust the rotation of the support shaft relative to the mounting frame by adjusting the distance between the first and second connectors. Because the horizontal axis is perpendicular to the support shaft, the rotation adjustment component can drive the support shaft to rotate around the axis of the horizontal axis, and the fixing plate can rotate around the axis of the support shaft. Therefore, this blade installation auxiliary fixture can drive the blade on the fixing plate to rotate in two directions in space, thereby greatly improving the flexibility and accuracy of blade installation. This allows the blade on the fixing plate to adapt to various installation angles and positions at the installation site, significantly improving its practicality.

[0029] Using this blade installation method, the installation angle of the blades can be adjusted during the installation process to meet different installation position requirements, thereby improving the efficiency and quality of blade installation. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0043] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] like Figure 1 As shown, the present invention provides an auxiliary tooling for blade installation. The auxiliary tooling includes a fixed plate 1, a locking assembly 2, a support shaft 3, a mounting frame 4, and a rotation adjustment assembly 5. The locking assembly 2 is disposed on the fixed plate 1 and is used to apply a force to the blade 100 so that the blade 100 abuts against the fixed plate 1. The fixed plate 1 is rotatably disposed on the support shaft 3 about the axis of the support shaft 3. The mounting frame 4 is provided with a horizontal shaft 41 perpendicular to the support shaft 3, and the support shaft 3 is rotatably disposed on the horizontal shaft 41. The rotation adjustment assembly 5 includes a first connector 51 disposed on the mounting frame 4 and a second connector 52 disposed on the support shaft 3. The distance between the first connector 51 and the second connector 52 can be shortened or lengthened so that the support shaft 3 can rotate about the axis of the horizontal shaft 41 on the mounting frame 4. In this embodiment, the fixing plate 1 is used to abut against the blade 100. Since the fixing plate 1 is provided with a locking component 2, and the locking component 2 can apply a force to the blade 100 to make the blade 100 abut against the fixing plate 1, the locking component 2 can firmly fix the blade 100 to the fixing plate 1, ensuring the stability of the subsequent installation of the blade 100; the support shaft 3 is rotatably mounted on the horizontal shaft 41 of the mounting frame 4, and the first connector 51 and the second connector 52 of the rotation adjustment component 5 are respectively mounted on the mounting frame 4 and the support shaft 3. Since the distance between the first connector 51 and the second connector 52 can be shortened or lengthened, the rotation adjustment component 5 The rotation adjustment of the support shaft 3 relative to the mounting bracket 4 can be achieved by adjusting the distance between the first connector 51 and the second connector 52. Since the horizontal axis 41 is perpendicular to the support shaft 3, the rotation adjustment component 5 can drive the support shaft 3 to rotate around the axis of the horizontal axis 41, and the fixing plate 1 can rotate around the axis of the support shaft 3. Therefore, this blade installation auxiliary tooling can drive the blade 100 on the fixing plate 1 to rotate in two directions in space, thereby greatly improving the flexibility and accuracy of the blade 100 installation. This allows the blade 100 on the fixing plate 1 to adapt to various different installation angles and positions on the installation site, greatly improving its practicality.

[0047] Specifically, the connection position of the second connector 52 to the support shaft 3 is far away from the connection position of the support shaft 3 to the horizontal axis 41; the operator can drive the support shaft 3 to rotate around the horizontal axis 41 by adjusting the distance between the first connector 51 and the second connector 52.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, the fixed plate 1 has inserts 11 at both ends corresponding to the support shaft 3. The two ends of the support shaft 3 are inserted into the inserts 11, and the support shaft 3 is clearance-fitted with the inner wall of the insert 11. In this embodiment, both ends of the fixed plate 1 are provided with inserts 11, and the two ends of the support shaft 3 are respectively inserted into the two inserts 11, thereby connecting with the fixed plate 1. The support shaft 3 is clearance-fitted with the inserts 11, so the support shaft 3 can rotate in the inserts 11. At the same time, the support shaft 3 can also drive the fixed plate 1 to rotate around the horizontal axis 41 through the insertion of the inserts 11.

[0049] Specifically, such as Figure 2 As shown, a locking member 12 is provided on the fixing plate 1. The locking member 12 can apply a force to the support shaft 3 so that the side of the support shaft 3 abuts against the inner wall of the insert 11. In this embodiment, the locking member 12 can apply a force to the support shaft 3 so that the support shaft 3 and the insert 11 remain relatively stationary, thereby positioning the fixing plate 1. Specifically, the operator adjusts the rotation angle of the blade 100 on the fixing plate 1 by rotating the fixing plate 1. After rotating to a suitable installation angle, the operator uses the locking member 12 to press the support shaft 3 against the insert 11, thereby preventing the fixing plate 1 from continuing to rotate freely relative to the support shaft 3, so that the blade 100 is kept at the specified installation angle.

[0050] Specifically, such as Figure 2 As shown, the locking member 12 is threadedly connected to the side wall of the insert 11, and the end of the locking member 12 extending out of the side wall of the insert 11 abuts against the support shaft 3. In this embodiment, the locking member 12 is provided with threads, and the side wall of the insert 11 is provided with a threaded hole that matches the locking member 12. The locking member 12 is threadedly connected to the insert 11; the end of the locking member 12 extends into the interior of the insert 11; when the fixing plate 1 is rotated to a suitable angle, the operator screws the locking member 12 so that the end of the locking member 12 abuts against the support shaft 3 and the support shaft 3 is pressed against the inner wall of the insert 11, thereby ensuring the relative fixation of the fixing plate 1 and the support shaft 3. The structure is simple and the operation is convenient.

[0051] Furthermore, such as Figure 1 and Figure 3As shown, the rotation adjustment assembly 5 also includes an adjustment sleeve 53, with both ends of the adjustment sleeve 53 threadedly connected to the first connector 51 and the second connector 52, respectively. Rotating the adjustment sleeve 53 in the forward direction allows the first connector 51 and the second connector 52 to move closer together, while rotating it in the reverse direction allows the first connector 51 and the second connector 52 to move further apart. In this embodiment, the first connector 51 and the second connector 52 are hinged to the mounting bracket 4 and the support shaft 3, respectively, and the connection point between the second connector 52 and the support shaft 3 is away from the connection point between the support shaft 3 and the horizontal axis 41. Both the first connector 51 and the second connector 52 are rod-shaped structures and both have external threads. The adjustment sleeve 53 has internal threads that match the external threads on the first connector 51 and the second connector 52. Both ends of the adjustment sleeve 53 are threadedly connected to the first connector 51 and the second connector 52, respectively. When the adjustment sleeve 53 is rotated in the forward direction... When the adjusting sleeve 53 is rotated, the first connector 51 and the second connector 52 can extend deeper into the adjusting sleeve 53, thus bringing them closer together. When the adjusting sleeve 53 is rotated in the opposite direction, the first connector 51 and the second connector 52 can exit the adjusting sleeve 53, thus moving them away from each other. It can be understood that since the adjusting sleeve 53 is threadedly connected to the first connector 51 and the second connector 52 respectively, the rotating adjusting assembly 5 has a self-locking function. When the adjusting sleeve 53 is rotated to the appropriate position, the support shaft 3 can remain stable at that angle. The rotation angle of the support shaft 3 can be adjusted by turning the adjusting sleeve 53, without the need for a separate drive mechanism, making the operation simple, time-saving, and labor-saving.

[0052] Specifically, such as Figure 1 and Figure 2 As shown, the locking assembly 2 includes a screw 21, a pressure plate 22, and a pressing bolt 23. The screw 21 is mounted on the fixing plate 1, the pressure plate 22 passes through the screw 21, and the pressing bolt 23 is screwed onto the screw 21 and abuts against the pressure plate 22. The pressing bolt 23 can apply force to the pressure plate 22, so that the pressure plate 22 abuts against the blade 100. In this embodiment, by screwing the pressing bolt 23 onto the pressure plate 22, the pressure plate 22 is pressed against the blade 100, thereby fixing the blade 100. The structure is simple and the operation is convenient.

[0053] Specifically, such as Figure 1 and Figure 2As shown, the fixing plate 1 includes a back plate 13 and a bottom plate 14 connected to each other. The bottom plate 14 is used to support the blade 100, and the back plate 13 is used to abut against the blade 100. Screws 21 are disposed on the back plate 13. In this embodiment, the back plate 13 and the bottom plate 14 are integrally formed to form an L-shaped fixing plate 1. When fixing the blade 100, the blade 100 is placed vertically on the bottom plate 14 and fixed to the back plate 13 by the locking assembly 2. Specifically, two screws 21 are provided on the back plate 13, and the blade 100 is placed between the two screws 21. The support shaft 3 is disposed on the side of the back plate 13 away from the locking assembly 2.

[0054] Furthermore, such as Figure 1 As shown, the blade installation auxiliary fixture also includes a mounting base 6, with a mounting frame 4 mounted on the mounting base 6. Multiple pads 7 are evenly spaced on the side of the mounting base 6 facing away from the mounting frame 4. In this embodiment, the mounting frame 4 is fixed to the mounting base 6, thereby enhancing the stability of the fixing plate 1. Multiple pads 7 are evenly spaced on the bottom surface of the mounting base 6, creating a space between adjacent pads 7. This facilitates the insertion of a forklift fork into the space, allowing for the movement and lifting of the entire blade installation auxiliary fixture. Therefore, workers no longer need to use lifting equipment to laboriously transport the blade 100, greatly improving the efficiency and quality of blade 100 installation.

[0055] Specifically, such as Figure 1 As shown, the mounting frame 4 includes an upright beam 42 and a diagonal brace beam 43. The upright beam 42 is mounted on the mounting base 6, and the horizontal shaft 41 is mounted on the upright beam 42. One end of the diagonal brace beam 43 is fixed to the mounting base 6, and the other end of the diagonal brace beam 43 is fixed to the upright beam 42. In this embodiment, the upright beam 42 and the diagonal brace beam 43 are integrally formed to form a mounting frame 4 with a triangular longitudinal section, which improves the stability of the support for the fixing plate 1. Specifically, the top of the upright beam 42 is provided with a horizontal shaft 41, and a connecting rod 31 is provided on the side of the support shaft 3 facing the mounting frame 4. The end of the connecting rod 31 passes through the horizontal shaft 41 through a bearing, so the support shaft 3 can rotate freely relative to the horizontal shaft 41.

[0056] This embodiment also provides a blade installation method, using the aforementioned blade installation auxiliary fixture, including the following steps:

[0057] S1. Place the blade 100 on the fixing plate 1 and use the locking assembly 2 to lock the blade 100 onto the fixing plate 1. In this embodiment, the operator places the blade 100 to be installed on the base plate 14 of the fixing plate 1 and screws the abutment bolt 23 of the locking assembly 2, thereby firmly fixing the blade 100 onto the back plate 13 of the fixing plate 1 by the pressure plate 22.

[0058] S2. Adjust the distance between the first connector 51 and the second connector 52 so that the fixing plate 1 drives the blade 100 to rotate around the axis of the horizontal axis 41 to a suitable vertical angle for installation. In this embodiment, after the blade 100 is fixed on the fixing plate 1, the operator adjusts the distance between the first connector 51 and the second connector 52 by turning the adjusting sleeve 53, thereby adjusting the vertical angle of the blade 100 on the fixing plate 1. Specifically, the operator turns the adjusting sleeve 53 according to the actual installation position on site, thereby adjusting the pitch of the fixing plate 1 so that the blade 100 on the fixing plate 1 meets the vertical angle of the installation position.

[0059] S3. Horizontally rotate the fixing plate 1 so that the blade 100 on the fixing plate 1 rotates around the axis of the support shaft 3 to a suitable horizontal angle for installation. In this embodiment, the fixing plate 1 and the support shaft 3 are rotatably engaged, and the fixing plate 1 is provided with a locking member 12. After the vertical angle of the fixing plate 1 is adjusted, the operator horizontally rotates the fixing plate 1 to rotate the blade 100 on the fixing plate 1 to a horizontal angle that satisfies the installation position, and then uses the locking member 12 to fix the horizontal position of the fixing plate 1.

[0060] S4. Use a forklift to lift the mounting frame 4 to the designated installation position and install the blade 100. In this embodiment, the mounting frame 4 is fixedly mounted on the mounting base 6, and multiple pads 7 are evenly spaced on the side of the mounting base 6 facing away from the mounting frame 4. After the vertical and horizontal angles are adjusted, the workers use a forklift to move and lift the mounting base 6 from the bottom to the designated installation position. During the installation process, the workers can also adjust the angle of the fixing plate 1 at any time according to the actual situation on site to ensure that the blade 100 can be aligned with the mounting holes on the hull.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
