Detailed description of the invention
Referring to figs. 1 through Fig. 4, platform keel block is described further.
A kind of platform keel block, including keel block main body 0, suspension arrangement 1 and stopping means 2.
Referring to figs. 1 to Fig. 3, keel block main body 0 is set to triangle, and with being easy to the ladder 8 of repairing by climbing.Triangular supports Stability Analysis of Structures, can bear big pulling force, and lifeboat is from great, and keel block pulling force is also big, and triangular supports can effectively reduce keel block and be involved the risk to deformation by pulling force.And lifeboat is flat is hung in below keel block main body 0, support near lifeboat place for settings that slope inwardly, can collision free, ladder 8 is used for climbing to repair and maintenance equipment in keel block main body 0.
What suspension arrangement 1 included that two ends are directly connected to lifeboat and movable pulley respectively hang ship chain 3, is positioned on winch table 5 hangs hanging ship arm 4, playing ship lock and remote control unit 6 for what control suspension arrangement 1 duty of ship for fixing wheels 183 and hanging.
Hanging ship chain 3 one end to be connected with movable pulley, when wheels 183 move, movable pulley can move up and down and change the position of lifeboat, and can be substantially reduced pulling force suffered by keel block.Movable pulley number is more many, the pulling force that can reduce is more many, in this utility model, steel wire rope 182 is drawn from winch 181, the horizontal break-in fixed pulley 1831 on first pile warp winch table 5, changes direction in the horizontal direction, draw to winch table 5 two ends, further around turning to fixed pulley group 1832 through winch table 5 two ends, horizontal direction transfer vertical direction to, reach fixed pulley and change nyctitropic purpose；Turning to the movable pulley between fixed pulley group 1832 to play the effect reducing steel wire rope 182 stress, this utility model adopts two movable pulleys, it is possible at least reduce the pulling force of half, significantly reduces winch 181 required drive, reduces tension intensity suffered by winch 181.
With reference to Fig. 4, horizontal break-in fixed pulley 1831 in wheels 183 includes being positioned on winch table 5 deviates from the first horizontal break-in fixed pulley 18311 and the second horizontal break-in fixed pulley 18312 of winch 181, steel wire rope 182 is transferred and is changed 180 ° in horizontal direction after the horizontal break-in fixed pulley 18311 of pile warp first, then guides the 3rd horizontal break-in fixed pulley 18313 near winch 181 into.Steel wire rope 182 is drawn by the 3rd horizontal break-in fixed pulley 18313 and the second horizontal break-in fixed pulley 18312, and what pile warp was positioned at winch 181 platform 5 two ends respectively turns to fixed pulley group 1832.Fixed pulley group 1832 is turned to include turning to fixed pulley group 18321 near the first of winch 181 end and deviating from the second of winch 181 end and turn to fixed pulley group 18322.First turns to fixed pulley group 18321 to include fixed pulley a coaxial in horizontal direction and fixed pulley b, is provided with the first movable pulley 15 between fixed pulley a and fixed pulley b；Second turns to fixed pulley group 18322 to include fixed pulley c coaxial in horizontal direction and fixed pulley d surely, is provided with the second movable pulley 16 between fixed pulley c and fixed pulley d.
During winch work, two steel wire ropes 182 drawn by winch, the first horizontal break-in fixed pulley 18313 of pile warp the 3rd of one of steel wire rope 182, turnover 90 ° in the horizontal direction, further around through fixed pulley c13 and fixed pulley d14, being connected with between fixed pulley c13 and fixed pulley d14 hangs on the second movable pulley 16 on steel wire rope 182, is fixedly connected on platform support 10 after steel wire rope 182 pile warp fixed pulley d14；The two of steel wire rope 182 are drawn by winch 181, the turnover horizontal break-in fixed pulley 18311 of pile warp first, after horizontal direction changes 180 °, further around through the second horizontal break-in fixed pulley 18312, then pile warp fixed pulley b12 and fixed pulley a11, being connected with between fixed pulley b12 and fixed pulley a11 hangs on the first movable pulley 15 on steel wire rope 182, is fixedly connected on platform support 10 after steel wire rope 182 pile warp fixed pulley a11.Movable pulley in use reduces pulling force, and fixed pulley is then used for changing direction.
Pulling force when hanging ship arm 4 for bearing lifeboat by flat hanging and the position of fixing wheels 183, play ship lock and remote control unit 6 be used for controlling suspension arrangement 1 and transfer and mention lifeboat.
Stopping means 2 include ship for supporting lifeboat on keel block support 7, the fence 9 that shields and for fastening the securing member 17 between each parts of keel block.
With reference to Fig. 3, ship support 7 is spacing in lifeboat both sides, can either support lifeboat, simultaneously spacing with hanging ship chain 3, is prevented from again lifeboat and moves flat hanging in process.Fence 9 can limit the position of winch 181, and can play the function fastener 17 protecting winch 181 for fastening the connection between each parts of keel block.
Securing member 17 includes the bolt and nut for tightening parts, plays the spring washer of cushioning effect and the rivet of plain washer and parts of riveting tightly.Different secure components combination uses can make fastening effect promote, and spring washer etc. can play cushioning effect, minimizing rigid shock, increases the service life.
Above-mentioned specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
