Description
Technical Field
The utility model relates to an automatic unhooking device that gasbag buoyancy was salvaged under water.
Background
At present, generally, a rubber air bag is inflated to provide buoyancy to perform salvage or underwater installation construction operation, a sling is usually tied outside the air bag, and the object to be salvaged is fixed at the lower part of the sling through a connecting rigging. In practical application, the sling is often dismantled underwater, a diver needs to dive to a working position to remove the sling, and if the depth of a working water area is large or the water quality is turbid and the visual field is poor, higher requirements are provided for the operation skills and the guarantee equipment of the diver, so that the underwater risk of the operator is increased.
Disclosure of Invention
For solving above technical not enough, the utility model provides a make things convenient for the dismouting, reduce the automatic unhooking device that gasbag buoyancy salvaged under water of operating personnel operational risk.
The utility model discloses a realize through following measure:
the utility model provides an automatic unhooking device that gasbag buoyancy was salvaged under water, includes lower lug plate and lower shackle, open at lug plate lower extreme middle part edge down has the joint opening of upwards extending, and the side of lower lug plate leaves the welding area, shackle end extends down has two rings side by side and spaced, has worn jointly in two rings and can get into the interior round pin axle of joint opening, and the interval between two rings is greater than the lower lug plate thickness of joint opening part, and lower shackle is connected with the hoist cable, the gasbag has been binded to the hoist cable.
The aforesaid still includes the ear of hanging, it has downwardly extending's joint opening to go up ear of hanging upper end middle part edge, the hoist cable is connected with the shackle, the end extension of going up the shackle has two just spaced tourus side by side, has worn the round pin axle that can get into in the joint opening jointly in two tourus, and the interval between two tourus is greater than the lower lug plate thickness of joint opening part.
The lower lifting lug plate is a vertical plate which is narrow at the left and wide at the right, the welding area is positioned at the right side edge of the lower lifting lug plate, the bottom of the clamping opening is arc-shaped and can be matched with the pin shaft, and the distance between the bottom and the opening of the clamping opening is gradually increased.
And the side edge of the lower lifting lug plate is provided with a magnet.
The utility model has the advantages that: when the air bag is deflated, automatic unhooking is realized, underwater sling dismounting is avoided, the operation is more convenient, the workload of operators is greatly reduced, the requirements on the operation skills and the guarantee equipment of divers are not high, and the underwater risk of the operators is reduced.

Fig. 3 is the structure schematic diagram of the connecting part of the pin shaft and the lower lug plate of the present invention.
Fig. 4 is a schematic structural view of another installation state of the present invention.
Wherein: 1 lower lifting lug plate, 1-4 welding area, 2 air bag, 21 sling, 3 lower shackle, 4 fixing plate, 5 upper shackle, 6 upper lifting lug plate, 11 clamping opening and 31 pin shaft.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
as shown in fig. 1, 2, 3, an automatic unhooking device that gasbag buoyancy was salvaged under water, including lower lug plate and lower shackle, open at lug plate lower extreme middle part edge down has the joint opening of upwards extending, and the side of lower lug plate leaves the welding area territory, shackle end extension has two rings body side by side and interval down, has worn jointly in two rings body and has got into the intraoral round pin axle of joint, and the interval between two rings body is greater than the lower lug plate thickness of joint opening part, and lower shackle is connected with the hoist cable, the gasbag has been binded to the hoist cable.
As shown in fig. 4, still include the ear of hanging, it has downwardly extending's joint opening to go up ear of hanging upper end middle part edge, the hoist cable is connected with the shackle, the last extension of shackle has two rings side by side and spaced, has worn the round pin axle that can get into in the joint opening jointly in two rings, and the interval between two rings is greater than the lower lug plate thickness of joint opening part. Lower lifting lug board is narrow right side wide riser in a left side, welding area is located the right side limit of lower lifting lug board, joint opening bottom be can with round pin axle matched with arc, the joint opening from bottom to open-ended interval crescent. And a magnet is arranged on the side edge of the lower lifting lug plate.
Firstly, the welding area of the lower lifting lug plate is welded on the fixed plate, or the lower lifting lug plate and the fixed plate are attracted together through a magnet. Under normal conditions, the air bag is inflated to provide buoyancy, the buoyancy strains the sling and the lower shackle, and the pin shaft of the lower shackle is ensured to be always in the opening of the lower lifting lug plate; when the air bag is deflated, gas in the air bag is discharged, buoyancy is reduced, the sling is stressed and reduced, when the buoyancy provided by the air bag is smaller than the weight of the sling and the weight of the lower shackle, the lower shackle moves downwards under the action of gravity, and the lower shackle pin shaft is separated downwards from the opening of the lower lug plate, so that automatic unhooking is realized. In order to improve the stability, an upper lifting lug plate and an upper shackle are adopted, the upper part of the air bag is also fixed by a sling, the upper lifting lug plate is similar to the lower lifting lug plate in structure, the upper shackle is similar to the lower shackle in structure, and the connection mode is basically the same.
The foregoing is only a preferred embodiment of this patent, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of this patent, and these modifications and substitutions should also be regarded as the protection scope of this patent.
