Description

Technical Field

[0001] This utility model belongs to the field of cage collection technology, specifically relating to a hydraulic tilting and lifting winch. Background Technology

[0002] The collection of offshore net cages is achieved by using a winch to drive the winding rope. Since the winch is located on the side of the ship, a flipping structure is often used to prevent damage and collisions. A Chinese patent (CN221082413U) discloses a deceleration winch lifting device that can flip the winch and separate the coupling, allowing the winch to idle. However, the coupling increases the outer length of the winch, thus requiring further improvement. Utility Model Content

[0003] This utility model provides the following technical solution: It includes a fixed base plate fixed to the side of a ship, a transmission connecting box and a hydraulic pushing mechanism mounted on the fixed base plate. The surface of the fixed base plate is first rotatably connected to an inwardly rotating plate via an inwardly rotating part. The surface of the inwardly rotating plate is fixedly connected to the hydraulic pushing mechanism. An outwardly rotating part is provided on the side of the inwardly rotating plate away from the inwardly rotating part. The transmission connecting box and the inwardly rotating plate are rotatably connected via the outwardly rotating part. A hydraulic motor is mounted on the side of the transmission connecting box, and a winch is rotatably connected to the other side of the transmission connecting box. The hydraulic motor provides rotational power to the winch. A connecting pin is fixedly connected to the outer side of the transmission connecting box. A connecting plate is rotatably connected to the output end of the hydraulic pushing mechanism, and the other end of the connecting plate is rotatably connected to the connecting pin. The hydraulic pushing mechanism, mounted on the top surface of the inwardly rotating plate, drives the transmission connecting box to rotate outward.

[0004] The transmission connection box is internally rotatably connected to a drive gear, a rotating shaft, and a sliding gear. The rotating shaft is fixedly connected to the winch. A groove is provided on the circumference of the rotating shaft for the sliding gear to slide. The rotating shaft and the sliding gear rotate synchronously. The sliding gear meshes with the drive gear. A shift fork control lever is provided on the side of the transmission connection box to drive the sliding gear to slide on the rotating shaft.

[0005] The top surface of the internal tilting plate is rotatably connected to a box locker, the end of the box locker is fixedly connected to an arc-shaped plate, and the bottom side of the transmission connection box is fixedly connected to a locking pin that cooperates with the arc-shaped plate.

[0006] The fixed base plate has holes at its four corners for fixed connection with the ship's side.

[0007] The transmission connection box has a steel pipe frame installed on its side to protect the winch.

[0008] The inboard tilting plate and the fixed base plate are fixedly connected by screws and screw holes.

[0009] The beneficial effects of this utility model are:

[0010] The winch and transmission connection box are integrated into one structure, eliminating the need for a separate substructure. Utilizing the transverse length of the transmission connection box, the hydraulic motor drives the drive gear to rotate. Due to the slotted structure of the rotating shaft, the sliding gear can only slide along the axial direction of the rotating shaft to achieve engagement and disengagement with the drive gear. The sliding gear is controlled to slide on the rotating shaft via a lever with a shift fork, thereby realizing the power connection and disengagement between the winch and the hydraulic motor. After disengagement, the winch can idle, thus reducing the winch's external extension and improving operational safety. A hydraulic pushing mechanism is set to drive the entire transmission connection box to flip outwards. The transverse design allows for the addition of a hydraulic pushing mechanism, reducing the overall external extension of the winch on the hull. The hydraulic pushing mechanism also reduces the labor intensity of manual flipping.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1-5The present invention provides the following technical solution: a fixed base plate 1 fixed to the side of the ship, a transmission connecting box 4 and a hydraulic pushing mechanism 7 installed on the fixed base plate 1. The surface of the fixed base plate 1 is first rotatably connected to the inward turning part 3 to the inward turning plate 2. The surface of the inward turning plate 2 is fixedly connected to the hydraulic pushing mechanism 7. An outward turning part 6 is provided on the side of the inward turning plate 2 away from the inward turning part 3. The transmission connecting box 4 and the inward turning plate 2 are rotatably connected through the outward turning part 6. A hydraulic motor 41 is installed on the side of the transmission connecting box 4. A winch 5 is rotatably connected to the other side of the transmission connecting box 4. The hydraulic motor 41 provides rotational power to the winch 5. A connecting pin 44 is fixedly connected to the outer side of the transmission connecting box 4. A connecting plate 71 is rotatably connected to the output end of the hydraulic pushing mechanism 7. The other end of the connecting plate 71 is rotatably connected to the connecting pin 44. The hydraulic pushing mechanism 7 is installed on the top surface of the inward turning plate 2 to drive the transmission connecting box 4 to turn outward.

[0019] In this embodiment: the transmission connection box 4 is rotatably connected to a drive gear, a rotating shaft 51 and a sliding gear 52. The rotating shaft 51 is fixedly connected to the winch 5. The rotating shaft 51 has a groove on its circumference for the sliding gear 52 to slide. The rotating shaft 51 and the sliding gear 52 rotate synchronously. The sliding gear 52 meshes with the drive gear. The side of the transmission connection box 4 is provided with a shift fork control lever 43 that drives the sliding gear 52 to slide on the rotating shaft 51.

[0020] In this implementation plan: the fixed base plate 1 is fixed to the bed side, the inward flipping part 3 is set on the side of the fixed base plate 1 and the inward flipping part 3 is located inside the boat. The boat inward flipping plate 2 is rotatably connected to the fixed base plate 1 through the inward flipping part 3. The purpose of the boat inward flipping plate 2 is to drive the entire transmission connection box 4, winch 5 and hydraulic pushing mechanism 7 to flip into the boat hull at the same time, thereby increasing the boat's passability in narrow environments. The transmission connection box 4 is located on the other side of the internal tilting plate 2. The internal tilting plate 2 is tilted by the external tilting part 6 and the transmission connection box 4. The winch 5 and the transmission connection box 4 are integrated into one structure, eliminating the connecting substructure. Utilizing the lateral length of the transmission connection box 4, the hydraulic motor 41 drives the drive gear to rotate. Due to the slotted structure of the rotating shaft 51, the sliding gear 52 can only slide along the axial direction of the rotating shaft 51 to achieve engagement and disengagement with the drive gear. The sliding gear 52 is controlled to slide on the rotating shaft 51 by the lever 43, thereby realizing the power connection and disengagement between the winch 5 and the hydraulic motor 41. After disengagement, the winch 5 can rotate freely, thereby reducing the external length of the winch 5 and improving the safety of use. At the same time, the transmission connection box 4 is tilted outward as a whole, which can still meet the tilting requirements. Furthermore, the advantage of the horizontal arrangement is that it can increase the hydraulic pushing mechanism 7. The hydraulic pushing mechanism 7 can reduce the labor intensity of manual flipping. The front end of the hydraulic pushing mechanism 7 is connected to the connecting pin 44 through the connecting plate 71. When the hydraulic pushing mechanism 7 drives the transmission connecting box 4 to move, 77 can push the connecting pin 44 forward. Affected by the double-end rotation structure of the connecting plate 71, the transmission connecting box 4 can achieve downward flipping movement.

[0021] In this implementation scheme: the top surface of the internal tilting plate 2 is rotatably connected to the box locker 21, the end of the box locker 21 is fixedly connected to the arc plate 22, and the bottom side of the transmission connection box 4 is fixedly connected to the locking pin 42 that cooperates with the arc plate 22.

[0022] In this implementation scheme: Since the transmission connection box 4 is flipped as a whole, a locking pin 42 is fixed at the bottom side of the transmission connection box 4. The front end of the locking pin 42 is located inside the arc plate 22. The box lock 21 is rotatably connected to the ship's internal flip plate 2, and the arc plate 22 is fixedly connected to the box lock 21. Therefore, when the box lock 21 drives the arc plate 22 to rotate, when the arc plate 22 rotates above the locking pin 42, the locking pin 42 cannot move upward, thereby realizing the locking function of the transmission connection box 4.

[0023] The four corners of the fixed base plate 1 are provided with holes for fixed connection with the side of the boat; the holes are used to fix the connection between the fixed base plate 1 and the side of the boat.

[0024] A steel pipe frame is installed on the side of the transmission connection box 4 to protect the winch 5; the steel pipe frame can further protect the winch 5 and prevent it from being affected by minor collisions during driving.

[0025] The inboard tilting plate 2 and the fixed base plate 1 are fixedly connected by screws and screw holes; the fixed base plate 1 and the inboard tilting plate 2 are fixedly connected by screws to avoid the problem of the inboard tilting plate 2 swaying up and down in the environment of large waves.
