[0002] During the ship manufacturing and maintenance processes, as one of the key transmission components, the safety and stability of the transmission shaft are crucial. The main function of the transmission shaft is to transmit the power of the ship engine to the propeller to drive the ship forward. During the transmission process, the transmission shaft is prone to be affected by external impacts, vibrations, and environmental pollution, resulting in damage to the surface of the transmission shaft and even affecting its service life. Therefore, the need for protecting the transmission shaft is particularly important.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1-7 , a ship transmission shaft protection device, including a bottom support plate 1, a detachable top protection box 2 is arranged on the top of the bottom support plate 1, and the bottom support plate 1 and the top protection box 2 are connected by a disassembly mechanism;

[0024] Arc frames 10 are arranged at both ends of the top of the bottom support plate 1, bottom limiting rollers 8 are arranged on both sides of the top of the arc frames 10, a rectangular base 11 is fixed on the top of the arc frames 10, the bottom of the rectangular base 11 is fixedly connected to the bottom support plate 1, rotatable U-shaped rotating plates 7 are arranged on both sides of the arc frames 10, top limiting rollers 9 are arranged on the top of the U-shaped rotating plates 7, and a rotating mechanism for the rotation of the U-shaped rotating plates 7 is arranged inside the rectangular base 11;

[0025] The disassembly mechanism includes a horizontal limiting rod 4, four end corners of the horizontal limiting rod 4 are slidably connected to the horizontal limiting rod 4, a circular pull plate 3 is fixed at one end of the horizontal limiting rod 4, and a rigid spring 5 is arranged between the circular pull plate 3 and the top protection box 2 and outside the horizontal limiting rod 4;

[0026] Arc-shaped support seats 6 are fixed at the four end corners on the top of the bottom support plate 1. Circular limit holes that are in clearance fit with the horizontal limit rod 4 are provided inside the arc-shaped support seats 6. After the horizontal limit rod 4 is located inside the circular limit holes, it can limit the movement of the top protection box 2 on the top of the bottom support plate 1;

[0027] Here, when the top protection box 2 needs to be disassembled, the circular pull plate 3 is pulled in the direction away from the top protection box 2. The pulling of the circular pull plate 3 enables the horizontal limit rod 4 to slide inside the top protection box 2. The sliding of the horizontal limit rod 4 causes the rigid spring 5 to be stretched, enabling the horizontal limit rod 4 to move out of the inside of the arc-shaped support seat 6, thereby releasing the restriction of the horizontal limit rod 4 on the arc-shaped support seat 6 and enabling the top protection box 2 to be disassembled;

[0028] The rotating mechanism includes a hydraulic cylinder 19. The hydraulic cylinder 19 is located inside the rectangular base 11 and is fixedly connected to the rectangular base 11. The output end of the hydraulic cylinder 19 is fixed with a rectangular moving seat 18. Rectangular rotating columns 17 are rotatably connected to both sides of the rectangular moving seat 18 through pin shafts. Transverse optical rods 16 are arranged at both ends inside the rectangular base 11. A circular sliding tube 15 is slidably connected to the outer side of the transverse optical rod 16. One end of the rectangular rotating column 17 close to the circular sliding tube 15 is rotatably connected to the circular sliding tube 15 through a pin shaft. A rectangular moving block 14 is fixed to the side of the circular sliding tube 15 away from the transverse optical rod 16. A rectangular rotating plate 13 is rotatably connected to the top of the rectangular moving block 14. A longitudinal support rod 12 is rotatably connected to the top of the rectangular rotating plate 13 through a bearing. The longitudinal support rod 12 is located inside the U-shaped rotating plate 7 and is fixedly connected to the U-shaped rotating plate 7;

[0029] A circular chute is provided inside the circular sliding tube 15. The transverse optical rod 16 is located inside the circular chute and is slidably connected to the circular sliding tube 15 through the circular chute. Through the setting of the circular chute, the circular sliding tube 15 can slide horizontally on the outer side of the transverse optical rod 16;

[0030] Anti-slip sleeves are sleeved on the outer sides of the bottom limit roller 8 and the top limit roller 9, and anti-slip patterns are provided on the outer sides of the anti-slip sleeves. Through the setting of the anti-slip sleeves, the bottom limit roller 8 and the top limit roller 9 can better fit with the transmission shaft, improving the fixing efficiency of the bottom limit roller 8 and the top limit roller 9 on the transmission shaft.

[0031] Here, the operation of the hydraulic cylinder 19 enables the rectangular moving seat 18 to move. The movement of the rectangular moving seat 18 enables the circular sliding tube 15 to slide outside the transverse light rod 16 through the rectangular rotating column 17. The movement of the circular sliding tube 15 enables the rectangular moving block 14 to move. The movement of the rectangular moving block 14 enables the longitudinal support rod 12 to drive the U-shaped rotating plate 7 to rotate through the rectangular rotating plate 13, enabling the top limiting roller 9 to move towards the transmission shaft, so that the top limiting roller 9 can clamp the outside of the transmission shaft.

[0032] Working principle: When it is necessary to disassemble the top protective box 2, pull the circular pull plate 3 in the direction away from the top protective box 2. The pulling of the circular pull plate 3 enables the transverse limiting rod 4 to slide inside the top protective box 2. The sliding of the transverse limiting rod 4 causes the rigid spring 5 to be stretched, enabling the transverse limiting rod 4 to move out of the inside of the arc-shaped support seat 6, thereby releasing the restriction of the transverse limiting rod 4 on the arc-shaped support seat 6, so that the top protective box 2 can be disassembled;

[0033] Place the transmission shaft on the tops of the two bottom limiting rollers 8. The operation of the hydraulic cylinder 19 enables the rectangular moving seat 18 to move. The movement of the rectangular moving seat 18 enables the circular sliding tube 15 to slide outside the transverse light rod 16 through the rectangular rotating column 17. The movement of the circular sliding tube 15 enables the rectangular moving block 14 to move. The movement of the rectangular moving block 14 enables the longitudinal support rod 12 to drive the U-shaped rotating plate 7 to rotate through the rectangular rotating plate 13, enabling the top limiting roller 9 to move towards the transmission shaft, so that the top limiting roller 9 can clamp the outside of the transmission shaft.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
