Description
Technical Field
The utility model relates to a hook assembly especially relates to a lifeboat hook assembly.
Background
The existing lifeboat lifting hook device comprises a lifting hook, a lifting frame plate, a cable stop frame, a limiting plate, a stop block and a push-pull rod; the lifting hook is vertically and rotatably arranged between the two hanger plates, the cable stop frame is fixedly arranged between the two hanger plates at the front side of the lifting hook, the stop block is rotatably arranged between the two hanger plates at the lower end of the lifting hook, the rear end of the stop block is connected with the push-pull rod, and the front end of the stop block is arranged at the lower rear end of the lifting hook and used for driving the lifting hook to open and rotate; the limiting plate is rotatably arranged on the inner side of a hanger plate, the limiting plate is semicircular, the upper end of the limiting plate is provided with a swinging rod, a protrusion is arranged on the hook corresponding to the swinging rod, and the limiting plate is positioned right above the stop block; when the hook and the cable stop frame are closed, the stop block is pulled by the push-pull rod, the front end of the stop block drives the lower rear end of the hook to open and rotate, and meanwhile, the limiting plate rotates and falls to the stop block under the action of self weight so as to limit the push-pull rod to push the stop block upwards; only after the lifting hook is reset and closed, the limiting plate is driven by the protrusion on the lifting hook at the moment to remove the limitation on the stop block, and the push-pull rod can push the stop block upwards to reset; however, if a crew does not notice that dust, coal ash or grease on the mother ship is accumulated on the inner side surface of the hanger plate of the hook after weathering and is not cleaned in time during the maintenance of the hook, the crew can not freely rotate the limiting plate, and the crew cannot automatically rotate to the vertical position to limit the stop block, so that the limiting function of the limiting plate is lost.
Disclosure of Invention
To the shortcoming above, an object of the utility model is to provide a can prevent life boat hook assembly of limiting plate limit function inefficacy.
The technical content of the utility model is that a lifeboat hook device comprises a hook, a hanger plate, a cable stop frame, a limit plate, a stop block and a push-pull rod; the lifting hook is vertically and rotatably arranged between the two hanger plates, the cable stop frame is fixedly arranged between the two hanger plates at the front side of the lifting hook, the stop block is rotatably arranged between the two hanger plates at the lower end of the lifting hook, the rear end of the stop block is connected with the push-pull rod, and the front end of the stop block is arranged at the lower rear end of the lifting hook and used for driving the lifting hook to open and rotate; the device is characterized in that the limiting plate is rotatably arranged on the inner side of a hanger plate and is positioned right above the stop block; a first swing rod is arranged on one side of the upper end of the limiting plate; a second swing rod is arranged on the other side of the upper end of the limiting plate; a bulge is arranged on the lifting hook corresponding to the first swing rod and the second swing rod; the first swing rod is used for driving the limiting plate to remove rotation limitation on the stop block through the protrusion when the lifting hook is closed, and the second swing rod is used for driving the limiting plate to achieve rotation limitation on the stop block through the protrusion when the lifting hook is opened.
Compared with the prior art, the utility model the advantage that has do: the limiting plate is prevented from failing in limiting function by arranging the first oscillating rod and the second oscillating rod on the limiting plate.

Detailed Description
As shown in fig. 1, 2 and 3, a lifeboat hook apparatus comprises a hook 1, a hanger plate 2, a cable stopper 3, a stopper plate 4, a stopper 5 and a push-pull rod 6; the lifting hook 1 is vertically and rotatably arranged between the two hanger plates 2, the cable stop frame 3 is fixedly arranged between the two hanger plates 2 on the front side of the lifting hook 1, the stop block 5 is rotatably arranged between the two hanger plates 2 on the lower end of the lifting hook 1, the rear end of the stop block 5 is connected with the push-pull rod 6, and the front end of the stop block 5 is arranged at the lower rear end of the lifting hook 1 and is used for driving the lifting hook 1 to open and rotate; the device is characterized in that the limiting plate 4 is rotatably arranged on the inner side of a hanger plate 2, and the limiting plate 4 is positioned right above the stop block 5; a first swing rod 4.1 is arranged on one side of the upper end of the limiting plate 4; a second swing rod 4.2 is arranged on the other side of the upper end of the limiting plate 4; a bulge 1.1 is arranged on the lifting hook 1 corresponding to the first swing rod 4.1 and the second swing rod 4.2; first swinging arms 4.1 drives limiting plate 4 through arch 1.1 and removes the rotation restriction to stop block 5 when being used for lifting hook 1 to close, and second swinging arms 4.2 plays to drive limiting plate 4 through protruding 1.1 and realize the rotation restriction to stop block 5 when being used for the lifting hook to open.
The working principle of the utility model is that after the lifeboat is lifted to the water surface, the boat lifting rope of the lifeboat is positioned in the lifting hook 1, the lifting hook 1 and the cable stop frame 3 are closed, at the moment, the boat lifting rope needs to be released from the lifting hook 1, personnel in the lifeboat can drive the stop block 5 to rotate by pulling the push-pull rod 6, the front end of the stop block 5 drives the lower rear end of the lifting hook 1 to be opened and rotated, and meanwhile, the bulge 1.1 drives the limiting plate 4 to rotate by the second swinging rod to realize the rotation limitation of the stop block 5; when the lifting hook 1 is rotated and closed, the protrusion 1.1 drives the limiting plate 4 to rotate through the first swinging rod to realize the removal of the rotation limitation of the stop block 5; the stop block 5 is reset and rotated by pushing the push-pull rod 6.
