Description
Technical Field
The invention relates to an unmanned unhooking lifting hook.
Background
When the boat or the raft is lifted, the boat or the raft is lifted on the water surface, and the hook is operated by a person in the boat or the raft on the water surface to lift the boat or the raft to the storage position. When the unmanned ship is on the water surface, an operator can complete the hook underwater. In addition, the safety behind the hook needs to be manually released, and the hook cannot be automatically unlocked.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide an unmanned unhooking lifting hook. The simulation state does not need personnel to launch, and the object is released on the mother ship, so that the whole lowering process is safe and reliable. The whole process is simple to operate. The hook is finished without personnel launching; and manual unlocking is not needed, and personnel does not need to be launched when the unhooking lifting hook acts.
In order to achieve the purpose, the technical scheme of the invention is to design an unmanned unhooking lifting hook which comprises two side plates which are oppositely arranged, wherein the side plates are connected through a plurality of supporting columns, the lifting hook is hinged between the two side plates, a safety plate for limiting the rotation of the lifting hook is hinged between the two side plates, and the lifting hook is positioned below the safety plate; the end of the lifting hook, which is far away from the hinged end, is movably connected with the end of the safety board, which is far away from the hinged end, through a connecting plate which can relieve the locking state of the lifting hook and the safety board. Rotation that the protective plate can restrict the lifting hook when locking state for the lifting hook keeps a position (its shape of cooperation lifting hook, it can be in vertical state almost always, including the setting of spacing post, the rings of cover on the lifting hook can not break away from the lifting hook), and the connecting plate then can realize removing of protective plate and lifting hook locking state through pulling up the back, continue to pull up the connecting plate, then drive the lifting hook rotation again, realize the unhook action of rings and lifting hook of cover on the lifting hook, through the setting of mechanism, only through the action of a connecting plate of pulling up, just can realize removing two actions of insurance and unhook, and the design is ingenious, and the steam generator is simple in structure.
The technical scheme is that a lug for limiting the rotation of the lifting hook is arranged on the safety plate, and a protruding lifting hook root matched with the lug is arranged at the upper end of the lifting hook. The normal state lifting hook has the safety device insurance, through linkage earlier release insurance when pulling the unhook, the linkage lifting hook realizes the unhook again. The root of the hook is clamped by a safety device (namely a lug) in a normal state; the safety device in the unhooking state is pulled, and the safety device is linked to automatically release the clamping; the blocking is automatically released by linkage, and unhooking is completed.
The further technical scheme is that one end, far away from the hinged end, of the safety board is provided with a sliding groove, a bolt is arranged in the sliding groove in a sliding mode, the bolt is fixedly connected to a connecting plate, and the other end of the connecting plate is hinged to a lifting hook.
The further technical proposal is that a hanging ring which can be sleeved into the hook-shaped end part of the hanging hook is matched with the hanging hook, and the hanging hook is provided with a hanging hook hole for the rope to pass through. The action of the lifting hook (i.e. the lifting of the lifting ring on the lifting hook is completed without the person launching) is as follows: 1. before the lifting hook is put down, a rope is inserted into the lifting hook hole; 2. threading the rope into the suspension loop; 3. pulling the rope hoisting ring to be sleeved into the lifting hook; 4. the lifting ring is sleeved in the lifting hook.
The further technical scheme is that a through hole used for lifting the safety plate to unlock the safety plate and the lifting hook is arranged in the middle of the safety plate, and a lifting rope or a lifting cable is arranged in cooperation with the through hole.
A further technical scheme is that an upper limiting column and a lower limiting column of the safety plate are fixedly arranged between the two side plates, and the height of the gravity center of the safety plate is lower than the lower limiting column when the safety plate abuts against the lower limiting column. The safety plate is pressed on the lower limiting column due to the shape of the safety plate and the arrangement of the gravity center, the convex block abuts against the root of the lifting hook to form a locking state (or called as a safety state), and the lifting ring is hung on the hook-shaped end part of the lifting hook and cannot be separated from the lifting hook.
The further technical proposal is that the through hole is arranged close to the chute; the distance from the sliding groove to the hinge point of the safety plate is larger than twice the distance from the through hole to the hinge point of the safety plate. When needing the unblock, upwards pulling the insurance board, the insurance board rotates along the pin joint, and the bolt slides to the lower extreme from the upper end of spout, forms the state of unblock (also the lug of its lower surface of insurance board no longer is blocked by the lifting hook root that is the bulge form promptly), continues to pull up then to drive the lifting hook rotation for the rings that are covering on the lifting hook follow the lifting hook roll-off, accomplish the action of unhooking.
A further technical scheme is that the hoisting ring comprises a semi-annular hoisting ring body and a channel steel-shaped section which is integrally or fixedly arranged with the hoisting ring body, and two ends of the hoisting ring body are connected to the bottom surface of the channel steel-shaped section.
The further technical proposal is that the upper end of the lifting hook is provided with a shaft hole matched with the lifting hook shaft, and the lower end of the lifting hook is a hook-shaped end part; and a left bush and a right bush are arranged in a matching way with the shaft hole, and the inner diameter of each bush is matched with the shaft diameter of the hook shaft.
The further technical scheme is that two side faces of the channel steel-shaped section are respectively provided with nine round holes with the aperture of 11 mm; the aperture of the hook hole is 10 mm.
The invention has the advantages and beneficial effects that: an operator remotely pulls the linkage device lifting hook and the lifting ring to be separated from each other on the mother ship, and unhooking is achieved through remote control of the rope. The simulation state does not need personnel to launch, and the object is released on the mother ship, so that the whole lowering process is safe and reliable. The whole process is simple to operate. The hook is finished without personnel launching; and manual unlocking is not needed, and personnel does not need to be launched when the unhooking lifting hook acts. Through the setting of mechanism, only through the action of a pull-up connecting plate, just can realize two actions of relieving insurance and unhook, design benefit, simple structure.
