Description

Technical Field

[0001] This utility model belongs to the field of ship winch technology, and in particular relates to a winch clutch fork mechanism. Background Technology

[0002] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0003] Manned launching winches are a type of winch. They are used by ships for water rescue and salvage operations and have many functions, such as transmitting signals to life bells, constant tension follow-up, and emergency towing. In traditional technology, the winch drive mechanism has only one drive motor. When one drive motor fails, the equipment will fail.

[0004] CN1843886A, a high-tension ship positioning winch, discloses a high-tension ship positioning winch, which includes systems for power, speed change, drum assembly, rope laying, ratchet brake, rapid towing, constant tension, and control. The speed change system includes a planetary power shifting device and a power dual-flow device. The planetary power shifting device is equipped with an electric motor connected to a coupling, two speed-changing brakes, a high-speed brake, and a second-stage planetary carrier. The first-stage planetary carrier is connected to the second-stage sun gear, the first-stage gear ring is connected to the second-stage gear ring, and the coupling is connected to the high-speed brake. However, this method still cannot solve the aforementioned technical problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] See Figures 1-6 A winch clutch fork mechanism includes: a bracket 5; motors 6, with one motor 6 on each side of the bracket 5, the motors 6 being slidably mounted on the bracket 5; a clutch drive mechanism mounted on the bracket 5, the clutch drive mechanism being able to drive the motors 6 to slide, thereby causing the motors 6 to connect or disengage from the actuator; and a locking mechanism disposed on the clutch drive mechanism, the locking mechanism being able to lock at least one motor 6 in a state of connection with the actuator, and having two sets of winch drive motors 6, so that when one motor 6 malfunctions, the other motor 6 can be used; at the same time, the two motors 6 have a locking function to ensure that at least one motor 6 is always connected to the load end.

[0032] The clutch drive mechanism comprises: a first link 73, the first end of which is rotatably mounted on a bracket 5; a second link 74, the first end of which is hinged to the second end of the first link 73; a third link 75, the first end of which is hinged to the second end of the second link 74; and a connecting seat 76, fixedly mounted on a motor 6, and fixedly connected to the second end of the third link 75. Driving the first link 73 drives the second link 74, which in turn drives the third link 75. The third link 75 pulls the connecting seat 76, thereby pulling the motor 6 to move, achieving the purpose of engagement or disengagement.

[0033] Each of the two motors 6 is equipped with a clutch drive mechanism, which drives the two motors 6 respectively.

[0034] The locking mechanism includes a locking block 72, which is fixedly connected to the first end of the first connecting rod 73. The locking block 72 has a locking surface 722 on its end face, and a notch 721 on the locking surface 722. When the first motor 6 is connected to the actuator, the locking surface 722 of the second motor 6's locking block 72 can pass through the notch 721 of the first motor 6's locking block 72, and the locking surface 722 of the second motor 6 locks the notch 721 of the first motor 6's locking block 72. Only when one motor 6 is engaged can the other motor 6 move, and the movement of the other motor 6 also locks the first motor 6. The two motors 6 have a locking function, ensuring that at least one motor 6 is always connected to the load end.

[0035] The clutch drive mechanism also includes a handle, which is fixedly connected to the first end of the first link 73. The handle can drive the first link 73 to swing. The handle serves to provide driving power.

[0036] The actuator is a drum, and the cable can be wound around the drum; the shaft of motor 6 is connected to the drum through a gear mechanism, thus playing a role in power transmission.

[0037] It also has a mounting base 71, on which the first end of the first connecting rod 73 is rotatably mounted for installation.

[0038] It also features a locking pin for locking the handle, which adapts to the handle and mounting base 71 to secure the handle. This ensures the drive unit remains connected to the load end while allowing for drive unit switching, providing safety protection and preventing accidental disconnection of the load end, which could cause the load to fall freely from the freewheel.

[0039] With the above structure, there are two sets of winch drive motors. If one motor fails, the other motor can be used. At the same time, the two motors have a locking function to ensure that at least one motor is always connected to the load.
