It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0036] Example 1, see Figure 1 to Figure 7 A hoisting tool for installing a full-rotation propeller includes a hoisting plate 1, a hoisting rope 5 for hoisting is arranged above the hoisting plate 1, and is installed on one side of a propeller hub 6, a propeller hub 6 is provided with a blade 7, a clamping block 29 for hoisting and clamping the propeller hub 6 is movably installed on the hoisting plate 1, and also includes:

[0037] The lifting adjustment mechanism is installed at the connection between the moving seat 11 and the lifting frame 10 and the lifting frame 10 and the lifting plate 1, and is used for fine-tuning and controlling processing according to the outer width of the hub 6 and the lifting distance.

[0038] Furthermore, the lifting adjustment mechanism includes a transmission screw 12 for adjusting the lifting position of the clamping block 29, the movable seat 11 is slidably connected to the lifting frame 10, and the movable seat 11 is threadedly connected to the transmission screw 12, the transmission screw 12 is rotatably installed on the lifting frame 10, the transmission screw 12 is fixedly connected to the output shaft of the first motor 13, and the lifting frame 10 is provided with a limit plate 14 for limiting the movable seat 11, and the lifting frame 10 is provided with a guide groove 15 for avoiding the first lifting rope 18 and the second lifting rope 25.

[0039] Furthermore, the lifting adjustment mechanism also includes a bidirectional screw 8 for adjusting the lifting spacing of the clamping block 29. The lifting frame 10 is connected to the lifting plate 1 by limited sliding through the guide rod 9, and the lifting frame 10 is threadedly connected to the bidirectional screw 8. The bidirectional screw 8 is rotatably connected to the inside of the lifting plate 1, and the bidirectional screw 8 is fixedly connected to the output shaft of the fourth motor 44.

[0040] Furthermore, a lifting ring 3 is fixedly connected to the lifting plate 1 through a reinforcing rib 2, a lifting hook 4 is adaptably connected to the lifting ring 3, and a lifting rope 5 for lifting is provided on the lifting hook 4.

[0041] Preferably, when installing and lifting the full-turn propeller, the lifting is performed by using the lifting rope 5 and the hook 4 connected by a crane, and the lifting plate 1 is lifted to a suitable range at the hub 6. According to the length of the hub 6, the output shaft of the fourth motor 44 drives the bidirectional screw 8 to rotate, and then the threaded connection of the bidirectional screw 8 and the guiding action of the guide rod 9 drive the lifting frames 10 to move closer to or away from each other, thereby realizing the adjustment of the lifting at the hub 6.

[0042] In addition, with respect to the position of the hub 6, the output shaft of the first motor 13 drives the transmission screw 12 to rotate, and under the limiting and guiding action of the limiting plate 14 that is threadedly connected to the transmission screw 12, the moving seat 11 can be driven to drive the clamping block 29 to adjust the corresponding position, thereby facilitating the clamping block 29 to be well adapted to be connected to the outer side of the hub 6 for lifting and clamping operations.

[0043] It should be particularly noted that the output shafts of the fourth motor 44 and the first motor 13 can be driven in both forward and reverse directions.

[0044] Embodiment 2, as Figure 1 to Figure 7 As shown, based on Example 1, this embodiment further includes a lifting and clamping control mechanism, which is installed on the clamping block 29 and is used to lift and control the clamping block 29 to limit the clamping of the hub 6. The lifting and clamping control mechanism includes a second lifting rope 25 for lifting and a first lifting rope 18 for lifting and clamping control. The first lifting rope 18 and the second lifting rope 25 are both movably connected to the inside of the moving seat 11, and the moving seat 11 is limitedly slidably connected to the lifting frame 10.

[0045] Furthermore, the lifting and clamping control mechanism also includes a connecting plate 27 and a lifting plate 40 for pulling the clamping block 29 for clamping. The first lifting rope 18 passes through the connecting plate 27 and one end is fixedly connected to the lifting plate 40. One end of the connecting rod 28 is rotatably installed on the connecting plate 27 through the first connecting shaft 31. The other end of the connecting rod 28 is rotatably installed and connected to the clamping block 29 through the second connecting shaft 32. The clamping block 29 is rotatably installed and connected to the lifting plate 40 through the third connecting shaft 33. A clamping groove 30 for clamping is provided on the clamping block 29.

[0046] Furthermore, the lifting and clamping control mechanism also includes a first winding roller 16 for pulling the first lifting rope 18 and a first wire roller 17 for guiding the first lifting rope 18. The first wire roller 17 is rotatably connected to the inside of the movable seat 11. The other end of the first lifting rope 18 is wound around and connected to the first winding roller 16. The first winding roller 16 is rotatably connected to the movable seat 11 through the first connecting rod 20 and the second connecting rod 21, and the first connecting rod 20 is limitedly slidably connected to the inside of the second connecting rod 21 through the first square shaft 22. The first connecting rod 20 is fixedly connected to the output shaft of the second motor 19, and the second motor 19 is fixedly installed on the outside of the movable seat 11.

[0047] Furthermore, the lifting and clamping control mechanism also includes a second winding roller 23 for pulling the second lifting rope 25 and a second wire roller 26 for guiding the second lifting rope 25. The second wire roller 26 is rotatably connected to the inside of the movable seat 11. One end of the second lifting rope 25 is fixedly connected to the connecting plate 27, and the other end of the second lifting rope 25 is wound around and connected to the second winding roller 23. The second winding roller 23 is rotatably connected to the movable seat 11 through a third connecting rod 41 and a fourth connecting rod 42. The third connecting rod 41 is limitedly slidably connected to the inside of the fourth connecting rod 42 through a second square shaft 43. The fourth connecting rod 42 is fixedly connected to the output shaft of the third motor 24. The third motor 24 is fixedly installed on the outside of the movable seat 11.

[0048] Preferably, in this embodiment, when performing the fixing operation of lifting, since the clamping block 29 is driven to a suitable lifting range, the output shafts of the second motor 19 and the third motor 24 can be driven to rotate synchronously, thereby realizing the synchronous lifting operation of the first lifting rope 18 and the second lifting rope 25, thereby facilitating the lifting operation of the clamping block 29.

[0049] In addition, when the hub 6 is limitedly clamped and fixed, the third motor 24 is no longer driven. At this time, the second motor 19 drives the first winding roller 16 to release the first lifting rope 18, so that the clamping block 29 is opened to facilitate the descent to a suitable clamping range. Then the second motor 19 drives the first winding roller 16 to reel in the first wire roller 17, thereby completing the clamping and fixing of the hub 6, that is, completing the lifting and clamping operation of the full-revolving rudder propeller, and under the subsequent synchronous driving operation of the second motor 19 and the third motor 24, the lifting operation of the full-revolving rudder propeller can be completed.

[0050] It should be particularly noted that the first connecting rod 20 is connected to the inside of the second connecting rod 21 by a limited sliding connection through the first square shaft 22, and the third connecting rod 41 is connected to the inside of the fourth connecting rod 42 by a limited sliding connection through the second square shaft 43, thereby ensuring the stability and feasibility of adjusting the above-mentioned hanging frames 10 to move closer or farther away from each other.

[0051] At the same time, this lifting method can accurately position and fix the full-rotation propeller, thereby greatly reducing the adjustment time during the installation process. This not only speeds up the installation speed, but also reduces the error rate during the installation process.

[0052] In addition, this lifting method can also ensure the stability of the full-rotation propeller during the lifting and installation process, preventing accidental injuries or equipment damage caused by shaking or tilting, thereby ensuring the stability and efficiency of its subsequent operation.

[0053] It should be particularly noted that the output shafts of the second motor 19 and the third motor 24 can be driven in both forward and reverse directions.

[0054] Embodiment 3, as Figure 1 to Figure 7 As shown, based on the above embodiment, this embodiment further includes an auxiliary lifting mechanism, which is installed on the outside of the clamping block 29 and is used to assist the clamping block 29 in clamping, lifting and limiting the hub 6.

[0055] Furthermore, the auxiliary lifting mechanism includes a first elastic band 34 and a first hanging ring 36 for auxiliary limiting the clamping of the hub 6, one end of the first elastic band 34 is fixedly connected to the clamping block 29 on one side, and the other end of the first elastic band 34 is provided with a first hook 35, and the clamping block 29 on the other side is provided with a first hanging ring 36 that is adapted to the first hook 35 for hanging and limiting.

[0056] Furthermore, the auxiliary lifting mechanism also includes a second elastic band 37 and a second hanging ring 39 for auxiliary limiting the lifting of the blade 7. The second elastic band 37 is fixedly connected to the clamping block 29 on one side, and a second hook 38 is provided at the other end of the second elastic band 37. The clamping block 29 on the other side is provided with a second hanging ring 39 that is adapted to the second hook 38 for hanging and limiting.

[0057] Preferably, in the present embodiment, when the clamping block 29 completes the clamping and fixing of the hub 6, it can be hung on the first hanging ring 36 through the first hook 35 on the first elastic band 34, and can also be hung on the second hanging ring 39 through the second hook 38 on the second elastic band 37. The connection between the first hook 35 and the first hanging ring 36 enables the first elastic band 34 to complete the clamping and limiting of the hub 6, and the connection between the second hook 38 and the second hanging ring 39 enables the second elastic band 37 to complete the lateral limiting of the blade 7, which greatly reduces the cumbersome operation and low work efficiency caused by manual multi-stage tethering, and is convenient for lifting, installation and use.

[0058] This auxiliary lifting method solves the problem that traditional installation methods often require a lot of manpower and material resources, and the lifting tooling can reduce the labor intensity of operators and reduce installation costs through mechanization and automation.

[0059] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
