The connecting plate drives the support block to move, so that one end of the support block contacts and pushes the check block to move together, until the eccentricity of the check block reaches 7±1mm, stop rotating the two positioning bolts, and finally tighten the locking nut until the bottom of the locking nut contacts the compression spring, then stop rotating the locking nut.

At the same time, the connecting plate drives the locking mouth of the support block to move along the outer surface trajectory of the support pin shaft and rotate around its axis. When the piston rod is fully extended, there is an eccentric distance between the center of the support pin shaft and the center line of the compression shaft, which generates a pulling force close to the direction of the rudder propeller on the support pin shaft.

[0056] When in use, the end of the piston rod 22 away from the cylinder 21 is hinged to the two connecting plates 141 through the first connecting pin 142, and the bottom end of the compression shaft 132 is hinged to the two connecting plates 141 through the second connecting pin 143; in the process of locking the lifting and full-turn steering propeller, the piston rod 22 extends, driving the two connecting plates 141 to move, and the two connecting plates 141 drive the compression shaft 132 to move downward in the vertical direction; in the process of loosening the lifting and full-turn steering propeller, the piston rod 22 retracts, driving the two connecting plates 141 to move, and the compression shaft 132 moves upward.

[0057] Embodiment 3: The basic content is the same as that of Example 1, except that: the two positioning bolts 121 are threadedly connected to the side plate 122 of the lower locking bracket 12, the two positioning bolts 121 are perpendicular to the straight line where the compression shaft 132 is axially located, and are located on the side of the two connecting plates 141 away from the piston rod 22.

[0058] When in use, during the installation of the locking component 1, the head ends of the two positioning bolts 121 are passed through the side plates 122 of the lower locking bracket 12 and contact the two connecting plates 141 respectively. The two connecting plates 141 are pushed to move by adjusting the positioning bolts 121, thereby driving the support block 145 to move. The support block 145 contacts the check block 136 and pushes the check block 136 to move. The eccentricity E of the check block 136 is adjusted. When the eccentricity E of the check block 136 meets the installation requirements, stop adjusting the positioning bolts 121. During use, the locking component 1 installed under this condition has a better and more stable locking effect.

[0059] Embodiment 4: The basic content is the same as Example 1, except that: the locking nut 134 and the compression spring 133 are located in the fixed bracket 131; one end of the compression spring 133 is in contact with the inner bottom of the fixed bracket 131, and the other end of the compression spring 133 is located at the lower part of the locking nut 134.

[0060] When in use, the compression spring 133 is sleeved on the outer side of the compression shaft 132, and the locking nut 134 is threadedly connected to the upper part of the compression shaft 132. During the installation of the locking component 1, the pressure of the compression spring 133 is adjusted by adjusting the position of the locking nut 134 to ensure that the installation of the locking component 1 meets the requirements and can work normally and reliably; in addition, during the locking process of the steering propeller upper support plate 4, the compression shaft 132 moves downward under the drive of the connecting plate 141, and generates downward pressure on the compression spring 133 through the locking nut 134.

[0062] When in use, during the installation of the locking component 1, after the position of the locking nut 134 is determined, the locking pin 135 and the nut are locked through threads, thereby fixing the locking nut 134, ensuring that the position of the locking nut 134 and the compression shaft 132 remains unchanged during operation, thereby improving the stability of the locking effect.

[0063] Embodiment 6: The basic content is the same as Example 1, except that: the oil cylinder 21 includes a rodless chamber 211, a rod chamber 212, and a piston 213; the piston 213 is located inside the oil cylinder 21 and is slidably connected to the inner wall of the oil cylinder 21; the piston rod 22 is located in the rod chamber 212, and the piston rod 22 is fixedly connected to one side of the piston 213; the hydraulic control component 3 includes a first high-pressure oil circuit T1, a second high-pressure oil circuit T2, an electromagnetic reversing valve 31, and two speed regulating valves 32; the electromagnetic reversing valve 31 is respectively connected to the first high-pressure oil circuit T1 and the second high-pressure oil circuit T2; the first high-pressure oil circuit T1 is connected to one of the speed regulating valves 32 and then connected to the two rod chambers 212; the second high-pressure oil circuit T2 is connected to the other speed regulating valve 32 and then connected to the two rodless chambers 211.

[0064] When in use, each lifting and fully rotating rudder propeller is provided with a left and right set of locking components 1 and hydraulic actuator components 2, and the electromagnetic reversing valve 31 is turned to the extending direction b, so that the high-pressure oil passes through the second high-pressure oil circuit T2 and passes through the speed regulating valve 32 to reach the rodless chamber 211 of the cylinder 21. The oil entering the rodless chamber 211 drives the piston rod 22 to extend, so that the locking component 1 cooperates with the corresponding hydraulic actuator component 2 to lock the upper support plate 4 of the rudder propeller; the electromagnetic reversing valve 31 is turned to the retracting direction a, so that the high-pressure oil passes through the first high-pressure oil circuit T1 and passes through the speed regulating valve 32 to reach the rod chamber 212 of the cylinder 21. The oil entering the rod chamber 212 drives the piston rod to retract, so that the locking component 1 cooperates with the corresponding hydraulic actuator component 2 to loosen the upper support plate 4 of the rudder propeller; at the same time, the speed regulating valve 32 controls the working speed of the hydraulic control component 3 by controlling the flow of high-pressure oil.

[0065] Embodiment 7: The basic content is the same as that of Example 1, except that: the connecting assembly 14 also includes an elastic pin 147; the elastic pin 147 is located in the middle position of the lower part of the two connecting plates 141, and the two ends of the elastic pin 147 are respectively fixedly connected to the two connecting plates 141; the other end of the support block 145 is provided with an arc-shaped opening 1452 adapted to the elastic pin 147.

[0066] During use, when the lifting and fully rotating propeller is loosened, the piston rod 22 retracts, driving the two connecting plates 141 to move toward the side close to the piston rod 22, thereby driving the elastic pin 147, the cylindrical rod 144, and the support block 145 to move in the same direction, so that the support block 145 is separated from the support pin 146. The support block 145 rotates downward around the cylindrical rod 144 due to its own gravity until the arc-shaped opening 1452 of the support block 145 contacts the elastic pin 147. The elastic pin 147 limits the support block 145 to prevent the locking opening 1451 from turning completely downward, thereby facilitating the support block 145 to move and rotate along the outer circular surface trajectory of the support pin 146 again when locking the lifting and fully rotating propeller.

[0069] Embodiment 9: The basic content is the same as that of Example 1, except that: the method for using the lifting and fully rotating propeller hydraulic locking device comprises the following steps: Step 1: first retract the steering propeller so that the upper locking bracket 11 contacts the fixed bracket 131; Step 2: First, fully retract the piston rod 22 to make the two connecting plates 141 reach the loosened position A, and then loosen the locking nut 134 until the bottom end of the locking nut 134 is no longer in contact with the compression spring 133, so that the compression spring 133 has no pre-tightening force; Step 3: First, fully extend the piston rod 22 so that the two connecting plates 141 reach the locking position B, then rotate the two positioning bolts 121 so that the head ends of the two positioning bolts 121 contact the corresponding connecting plates 141 respectively, and then continue to rotate the two positioning bolts 121 so that the two positioning bolts 121 push the two connecting plates 141 to move to the side close to the check block 136, and the connecting plate 141 drives the support block 145 to move so that one end of the support block 145 contacts and pushes the check block 136 to move together, until the eccentricity E of the check block 136 reaches 7±1mm, then stop rotating the two positioning bolts 121, and finally tighten the locking nut 134 until the bottom of the locking nut 134 contacts the compression spring 133, then stop rotating the locking nut 134, at this time the compression spring 133 is not subjected to force; Step 4: First, fully retract the piston rod 22 to make the two connecting plates 141 reach the loosened position A, and then rotate the locking nut 134 downward to 3.5±0.5 turns; Step 5: First, fully extend the piston rod 22 so that the two connecting plates 141 reach the locking position B, then measure the distance C between the top of the compression shaft 132 and the top of the fixed bracket 131, then fully retract the piston rod 22 so that the two connecting plates 141 reach the loosening position A, then measure the distance D between the top of the compression shaft 132 and the top of the fixed bracket 131, and finally calculate the difference between D and C until the difference between D and C reaches 14±1mm; Step 6: Adjust the locking pin 135 to fix the locking nut 134 to complete the installation; Step 7: First adjust the hydraulic control assembly 3 to extend the piston rod 22, the piston rod 22 drives the connecting plate 141 to move, the connecting plate 141 drives the compression shaft 132 to move downward, so that the locking nut 134 applies downward pressure to the compression spring 133, and at the same time, the connecting plate 141 drives the cylindrical rod 144 to move, under the action of the check block 136, the cylindrical rod 144 drives the support block 145 to move along the outer surface track of the support pin shaft 146 and rotate around the axis of the support pin shaft 146. When the piston rod 22 is fully extended, the support pin shaft The center of 146 is away from the steering propeller and an eccentricity is generated between it and the center line of the compression shaft 132. Under the action of the compression spring 133, the support block 145 generates a pulling force on the support pin 146 in the direction close to the steering propeller. At this time, the downward pressure of the compression spring 133 acts on the support pin 146 in the opposite direction through the compression shaft 132 and the support block 145, so that the support pin 146 is simultaneously subjected to an upward pulling force. Under the action of these two pulling forces, the support plate 4 on the steering propeller is subjected to an upward clamping force, thereby completely locking the lifting full-turn steering propeller.

[0070] Embodiment 10: The basic content is the same as Example 9, except that: when the lifting and fully rotating propeller needs to be lowered, the hydraulic control component 3 is first adjusted to retract the piston rod 22, and the piston rod 22 drives the connecting plate 141 to move toward the side close to the cylinder 21. The connecting plate 141 drives the support block 145 to disengage from the support pin 146, and the pressure of the compression spring 132 is released, and the compression shaft 132 moves upward, so that the lifting and fully rotating propeller is in a loosened state.

[0071] Embodiment 11: The basic content is the same as Example 9, except that: in the sixth step, adjusting the locking pin 135 to fix the locking nut 134 means: first adjusting the locking pin 135 to lock the locking nut 134, and then applying grease to the compression spring 133, the cylinder 21, the piston rod 22, the locking pin 135 and the locking nut 134 respectively.

[0072] When in use, the locking nut 134 is locked by the locking pin 135 to prevent the locking nut 134 from changing position during use, thereby improving the locking and fixing effect of the present invention; after installation, grease is applied to the compression spring 133, the cylinder 21, the piston rod 22, the locking pin 135 and the locking nut 134 to reduce friction between the components during use and extend the service life of the present invention.

The connecting plate (141) drives the support block (145) to move so that one end of the support block (145) contacts and pushes the check block (136) to move together until the eccentricity (E) of the check block (136) reaches 7±1 mm, then stop rotating the two positioning bolts (121), and finally tighten the locking nut (134) until the bottom of the locking nut (134) contacts the compression spring (133), then stop rotating the locking nut (134), at which time the compression spring (133) is not subjected to force; Step 4: First, fully retract the piston rod (22) to allow the two connecting plates (141) to reach the loosened position (A), and then rotate the lock nut (134) downward to 3.5±0.5 turns; Step 5: First, fully extend the piston rod (22) so that the two connecting plates (141) reach the locking position (B), then measure the distance C between the top of the compression shaft (132) and the top of the fixed bracket (131), then fully retract the piston rod (22) so that the two connecting plates (141) reach the loosening position (A), then measure the distance D between the top of the compression shaft (132) and the top of the fixed bracket (131), and finally calculate the difference between D and C until the difference between D and C reaches 14±1 mm; Step 6: Adjust the locking pin (135) to secure the locking nut (134) to complete the installation; Step 7: First, adjust the hydraulic control assembly (3) to extend the piston rod (22), the piston rod (22) drives the connecting plate (141) to move, the connecting plate (141) drives the compression shaft (132) to move downward, so that the locking nut (134) applies downward pressure to the compression spring (133), and at the same time, the connecting plate (141) drives the cylindrical rod (144) to move, under the action of the check block (136), the cylindrical rod (144) drives the support block (145) to move along the outer surface trajectory of the support pin (146) and rotate around the axis of the support pin (146). When the piston rod (22) is fully extended, the The center of the support pin (146) is away from the steering paddle and an eccentric distance is generated between the center line of the compression shaft (132). Under the action of the compression spring (133), the support block (145) generates a pulling force on the support pin (146) in the direction close to the steering paddle. At this time, the downward pressure of the compression spring (133) acts on the support pin (146) in the opposite direction through the compression shaft (132) and the support block (145), so that the support pin (146) is simultaneously subjected to an upward pulling force. Under the action of these two pulling forces, the support plate (4) on the steering paddle is subjected to an upward clamping force, thereby completely locking the lifting full-rotation steering paddle.
