Abstract
The utility model relates to a device for completing a drop test for a free fall lifeboat by an external manual releaser in the process of ship building. The utility model is characterized in that thedevice comprises a free fall lifeboat frame (1), the free fall lifeboat (2), a steel wire rope (9), a manual releaser (3), a bottle gourd (5) and a fixing eye ring (4), wherein the free fall lifeboat(2) is arranged on the free fall lifeboat frame (1); the tail end of the free fall lifeboat (2) is connected with one end of the manual releaser (3) by the steel wire rope (9); and the other end of the manual releaser (3) is connected with the fixing eye ring (4) by the bottle gourd (5). In the utility model, the work can operate the manual releaser outside the free fall lifeboat to realize the no-person free fall of the free fall lifeboat only by arranging one special manual releaser and matching the accessories such as the steel wire rope, thereby avoiding the hurt caused by accident when the tester for operation in the lifeboat enters the water.
Description
(1) technical field
The utility model relates to and a kind ofly utilizes outside manual release device to finish the device that free fall lifeboat leaves test in the shipbuilding process.Belong to the shipbuilding technical field.
(2) background technology
In the shipbuilding process, the free fall lifeboat equipment (being mainly free fall lifeboat, free fall lifeboat frame and retracting device) that boats and ships are equipped with by rule specification is done under will and participating in the supervision of shipowner and ship inspection and is left test after completion is installed.The test method of general shipyard is: take 3～5 people in the ship, capacity according to ship, all the other personnel seats are replaced by sandbag (85kg/ bag), manual release operating means and emergent releasing operation device are arranged in the ship, after personnel advance ship, close the ship door, dressed life jacket, take a seat and fasten seat belts, the external staff cooperates the locking device of untiing free fall lifeboat and keel block, after all are ready, operating personnel operate releasing means in the ship, survival craft freely leaves down water (it highly is about 18 meters that routine leaves) along the free fall lifeboat frame, drives free fall lifeboat by testing crew in the ship then and finishes the correlation test project, reclaims free fall lifeboat and inspection at last.There is following problem in this above-mentioned conventional method:
Owing to after free fall lifeboat discharges, after the keel block track slides a segment distance, just break away from, become water under the freely falling body at last.If wherein keel block when actual location is installed and theoretical position variant, run into Ship Structure when survival craft breaks away from behind the keel block freely falling body, cause ship to turn over the people and die.
Therefore, there is the potential safety hazard that ship turns over, the people dies in the test method of above-mentioned routine in practical operation.
(3) summary of the invention
The purpose of this utility model is to overcome the drawback of the potential safety hazard that above-mentioned conventional test method exists, and providing a kind of does not need personnel to enter the survival craft operation can to finish the outside manual release device of utilization that free fall lifeboat leaves test and finish the device that free fall lifeboat leaves test.
The purpose of this utility model is achieved in that a kind ofly utilizes outside manual release device to finish the device that free fall lifeboat leaves test, described device comprises free fall lifeboat keel block, free fall lifeboat, wire rope, manual release device, cucurbit and fixing eye thimble, free fall lifeboat places on the free fall lifeboat keel block, the free fall lifeboat tail end links to each other with an end of manual release device by wire rope, and the other end of this manual release device links to each other with fixing eye thimble by cucurbit.
Connect outside manual release device and the outside ship hook of free fall lifeboat with wire rope, cucurbit, tighten up wire rope with cucurbit, the outside is established put hook to reach and draw the free fall lifeboat state fully, unclamp free fall lifeboat self locking device then, open outside manual release device, make free fall lifeboat leave river surface or sea automatically along the free fall lifeboat frame, arrange testing crew to take on other canoes testcraft at last again and drive free fall lifeboat and do sea trial, playback and the every pilot project of inspection free fall lifeboat, finish free fall lifeboat and leave test.
This manual release device one end broke off relations in the moment of manual operation handle, broke off relations and locking hook unclamps simultaneously, wire rope breaks away from, survival craft glides and automatically under water.Described manual release device is when bearing survival craft weight, and release unhook and locking hook activity simultaneously are freely.
The beneficial effects of the utility model are:
The utility model only need dispose a special manual release, and be equipped with annexes such as wire rope, the staff free fall lifeboat peripheral operation manual release device realize free fall lifeboat not the person of carrying leave, avoid testing crew under the survival craft built-in function, to occur during water unexpected and bring injury.
(4) description of drawings
Fig. 1 finishes the survival craft that free fall lifeboat leaves the device of test for the outside manual release device of the utility model utilization and freely leaves synoptic diagram.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is a manual release device structural representation of the present utility model.
Fig. 4 is the vertical view of Fig. 3.
Among the figure:
Free fall lifeboat keel block 1, free fall lifeboat 2, manual release device 3, fixedly eye thimble 4, cucurbit 5, deck 6, the water surface 7, rope 8, wire rope 9;
(5) embodiment
Referring to Fig. 1～2, the outside manual release device of the utility model utilization is finished the device that free fall lifeboat leaves test, by free fall lifeboat keel block 1, free fall lifeboat 2, wire rope 9, manual release device 3, cucurbit 5 and fixedly eye thimble 4 form.Described free fall lifeboat 2 places on the free fall lifeboat keel block 1, free fall lifeboat 2 tail ends link to each other with an end of manual release device 3 by wire rope 9, the other end of this manual release device 3 links to each other with fixing eye thimble 4 by cucurbit 5, this fixedly eye thimble 4 be fixed on the deck 6.
Specific operation process is as follows:
After sandbag is all put in the seat in the free fall lifeboat ship, couple together with the end of the satisfactory wire rope of rupture pull force free fall lifeboat and manual release device, the other end of manual release device cooperates fixedly eye thimble that wire rope is strained with cucurbit, as Fig. 3 and Fig. 4.After the wire rope tension, unclamp the locking device of free fall lifeboat both sides and free fall lifeboat keel block, after all work are ready,, realize water experiment under the free fall lifeboat by operating personnel's manual operation manual release device.Will be a sufficiently long rope on free fall lifeboat simultaneously, so that control the free movable of free fall lifeboat behind the water down, ship be driven and is finished correlation test on the testing crew then.
