[0002] In the process of shipbuilding and maintenance, the installation of propeller shafts is a critical and complex task. During installation, the propeller shaft needs to be precisely inserted into the shafting hole of the propeller to ensure the quality of the propeller after installation. Therefore, developing an auxiliary installation device for ship propeller shafts is of great practical significance.

[0003] A device for centering and auxiliary installation of a ship propeller shaft, as described in CN202752818U, includes a laser emitter, a light target, and a theodolite. The laser emitter is placed at the flywheel end of the main engine, and the light target is placed at the free end of the main engine, the front and rear ends of the stern tube, and the rudder mounting point. The theodolite is placed at the free end of the main engine and the rudder mounting point. A temporary bracket for propeller shaft installation is set at the front end of the stern tube. This device uses a light-illumination method to locate the position of the intermediate bearing, ensuring accurate axis centering and effectively controlling the assembly precision of the ship propeller shaft. Furthermore, the installation and disassembly of the temporary bracket and the guide tube shaft are very convenient and can save a significant amount of labor. At the same time, its cost is very low, making it suitable for widespread use in shipbuilding enterprises. However, while this device can be widely applied, it is generally not convenient for pushing the shaft, thus hindering convenient installation. It still presents some inconveniences during use and requires further improvement. Utility Model Content

There are still some inconveniences in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary installation device for a ship propeller shaft, comprising an installation platform, two slide rails at the top of the installation platform, two rail blocks slidably connected to one side of the top of each slide rail, a lower connecting plate fixedly installed at the top of several rail blocks, an upper connecting plate above the lower connecting plate, a clamping frame fixedly installed at the top of the upper connecting plate, a telescopic cylinder mounted on the top of the installation platform on one side of the slide rail via a bracket, one end of the telescopic cylinder being connected to the outer wall of the lower connecting plate, a vertical plate fixedly installed on the top of the installation platform on the other side of the slide rail, a three-jaw chuck mounted on the inner wall at the upper end of the vertical plate, a control panel mounted on the top of the installation platform in front of the slide rail, the output terminal of the microcontroller inside the control panel being electrically connected to the input terminals of the telescopic cylinder and the three-jaw chuck respectively.

[0006] Preferably, both sides of the top of the lower connecting plate are provided with lower connecting seats, and both sides of the bottom of the upper connecting plate are provided with upper connecting seats.

The input end of the lifting cylinder is electrically connected to the output end of the microcontroller inside the control panel. The top end of the lifting cylinder is connected to the bottom end of the upper connecting seat. The lifting cylinder is used to drive the upper connecting plate to move up and down.

[0008] Preferably, a lower V-shaped chuck is fixedly installed at the bottom of the clamping frame, and a threaded cylinder is fixed at the center of the top of the clamping frame. The threaded cylinder is used to accommodate the studs.

[0009] Preferably, limiting rails are provided on both inner walls of the upper end of the clamping frame, and studs are installed in the internal threads of the threaded cylinder. The limiting rails are used to limit the movement range of the upper connecting frame.

The upper V-shaped chuck is designed to cooperate with the lower V-shaped chuck to clamp and fix the propeller shaft to be installed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the auxiliary installation device for the ship propeller shaft not only achieves the purpose of easy and convenient installation of the propeller shaft, but also achieves the purpose of easy fixed installation of the propeller and its shaft, and also achieves the purpose of easy calibration of the propeller shaft.

[0012] (1) The lower connecting plate is driven to move horizontally by the telescopic cylinder, so that several rail blocks at the bottom of the lower connecting plate slide on the top of the slide rail, so that the rail blocks drive the shaft inside the clamping frame to move horizontally smoothly, so that the shaft is inserted into the propeller hole held by the three-jaw chuck, thereby achieving the purpose of easy and convenient installation of the propeller shaft.

[0013] (2) By setting up a three-jaw chuck, the columnar component of the propeller can be clamped and fixed. Then, by placing the shaft above the lower V-shaped chuck, when the handle is rotated, the stud rotates inside the threaded cylinder and slides downward, so that it drives the upper connecting frame to slide downward on the inner wall of the limit rail, and drives the upper V-shaped chuck to move down and contact the upper inner wall of the shaft, so that the upper V-shaped chuck cooperates with the lower V-shaped chuck to clamp and fix the shaft, thereby achieving the purpose of easily fixing and installing the propeller and its shaft.

[0014] (3) By activating two lifting cylinders simultaneously, the upper connecting plate is driven upward by the upper connecting seat to adjust the distance between the upper connecting plate and the lower connecting plate. This allows the shaft inside the clamping frame to be aligned with the propeller hole held by the three-jaw chuck, thus achieving the purpose of easy alignment of the propeller shaft.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: an auxiliary installation device for a ship propeller shaft, including an installation platform 1, two slide rails 3 at the top of the installation platform 1, two rail blocks 7 slidably connected to one side of the top of each slide rail 3, a lower connecting plate 4 fixedly installed at the top of several rail blocks 7, a lower connecting seat 10 on both sides of the top of the lower connecting plate 4, and an upper connecting seat 12 on both sides of the bottom of the upper connecting plate 6.

[0022] In use, the upper connecting seat 12 and the lower connecting seat 10 are used to house the lifting cylinder 11.

[0023] A lifting cylinder 11 is installed at the center of the top of the lower connecting seat 10. The input end of the lifting cylinder 11 is electrically connected to the output end of the microcontroller inside the control panel 2. The top of the lifting cylinder 11 is connected to the bottom end of the upper connecting seat 12.

[0024] In use, the lifting cylinder 11 is used to drive the upper connecting plate 6 to move up and down.

[0025] An upper connecting plate 6 is provided above the lower connecting plate 4. A clamping frame 13 is fixedly installed at the top of the upper connecting plate 6. A lower V-shaped clamp 19 is fixedly installed at the bottom of the clamping frame 13. A threaded cylinder 16 is fixed at the center of the top of the clamping frame 13.

[0026] In use, the threaded sleeve 16 is provided to accommodate the stud 14;

[0027] Limit rails 1301 are provided on both inner walls of the upper end of the clamping frame 13, and studs 14 are installed in the internal threads of the threaded cylinder 16.

[0028] In use, the movement range of the upper connecting frame 17 is limited by the setting of the limit rail 1301;

[0029] The top end of the stud 14 extends to the outside of the threaded cylinder 16 and is equipped with a rotating handle 15. The bottom end of the stud 14 extends to the outside of the threaded cylinder 16 and is rotatably equipped with an upper connecting frame 17. The outer wall of the upper connecting frame 17 is slidably connected to the inner wall of the limiting rail 1301. The bottom end of the upper connecting frame 17 is equipped with an upper V-shaped chuck 18.

[0030] In use, the upper V-clamp 18 is designed to work with the lower V-clamp 19 to clamp and fix the propeller shaft to be installed.

[0031] A telescopic cylinder 5 is mounted on the top of the mounting platform 1 on one side of the slide rail 3 via a bracket. One end of the telescopic cylinder 5 is connected to the outer wall of the lower connecting plate 4. A vertical plate 8 is fixedly mounted on the top of the mounting platform 1 on the other side of the slide rail 3. A three-jaw chuck 9 is mounted on the inner wall of the upper end of the vertical plate 8. A control panel 2 is mounted on the top of the mounting platform 1 in front of the slide rail 3.

[0032] In this embodiment, the propeller's cylindrical component is first clamped and fixed using a three-jaw chuck 9. The shaft is then positioned above the lower V-clamp 19. When the handle 15 is rotated, the stud 14 rotates and slides downwards inside the threaded cylinder 16, driving the upper connecting frame 17 to slide downwards along the inner wall of the limiting rail 1301. This causes the upper V-clamp 18 to move downwards and contact the upper inner wall of the shaft, whereby the upper V-clamp 18, in conjunction with the lower V-clamp 19, clamps and fixes the shaft. Then, two lifting cylinders 11 are simultaneously activated to... The upper connecting plate 6 is moved upward by the upper connecting seat 12 to adjust the distance between the upper connecting plate 6 and the lower connecting plate 4. This allows the shaft inside the clamping frame 13 to be aligned with the propeller hole held by the three-jaw chuck 9, facilitating the calibration of the propeller shaft. Finally, the lower connecting plate 4 is moved horizontally by the telescopic cylinder 5, causing several rail blocks 7 at the bottom of the lower connecting plate 4 to slide on top of the slide rail 3. This allows the rail blocks 7 to smoothly move the shaft inside the clamping frame 13 horizontally, inserting the shaft into the propeller hole held by the three-jaw chuck 9, thus completing the use of this auxiliary installation device.
