Traditional deepwater winch is all integrative-structure, and in the present embodiment, arranging rope device 6 and the first wall stand 11 and the 2nd wall stand 13 is split structure, described row's rope device 6 and adopting between the first wall stand 11 and the 2nd wall stand 13 removably connects, rope device 6 and the first wall stand 11 and the 2nd wall stand 13 is arranged with bolts described in the present embodiment, adopt convenient when deepwater winch is installed and transports in this way, reduce the weight of single carrying.
Described row's rope device 6 comprises the support 61 at two ends, two described supports 61 are fixedly installed some tail rods 62, reverse-flighted screw 63 also it is provided with between two described supports 61, described tail rod 62 and reverse-flighted screw 63 are provided with guide deflection sheave 64, described reverse-flighted screw 63 is parallel with described tail rod 62, described guide deflection sheave 64 is made up of framework 641 and the 2nd rotating shaft 642 being arranged in described framework 641 and the 3rd rotating shaft 643, described framework 641 and described 2nd rotating shaft 642, described 3rd rotating shaft 643 surrounds three-way rope hole 644, when rope closing, hawser is through three-way rope hole 644, moving back and forth hawser proper alignment on main drum 41 by guide deflection sheave 64, and the volume of deepwater winch is very big, the weight of guide deflection sheave 64 is also very big, in order to convenient, rope is taken out three-way rope hole, bottom and the framework 641 of the 2nd rotating shaft 642 of guide deflection sheave 64 are rotationally connected, upper end and framework 641 removably connect, at needs, rope is taken out like this or the 2nd rotating shaft 642 can be fallen down when putting into three-way rope hole 644, then rope is put into or take out three-way rope hole 644, forward the 2nd rotating shaft 644 to original position again to fix, rope so just can easily be put into three-way rope hole 644 or take out three-way rope hole 644, described 2nd rotating shaft, 642 times ends and described framework 641 are rotationally connected, 2nd rotating shaft 642 upper end and described framework 641 removably connect, described guide deflection sheave 64 also includes twisted wire machine 645, described twisted wire machine 645 is provided with rope, described rope one end is detachably connected on described 2nd rotating shaft 642 upper end, the other end is set around on described twisted wire machine 645. traditional demountable structure is generally be fixed with a bolt on rope, removably connect with the screw in the 2nd rotating shaft 642, dismantle like this and install and also comparatively bother, in the present embodiment, described 2nd rotating shaft 642 upper end is provided with suspension ring 646, described cable end is provided with drag hook 647, like this after the 2nd rotating shaft 642 is fallen down, put into or take out hawser and become convenient, guide deflection sheave 64 arranges twisted wire machine 645, make can being controlled of the 2nd rotating shaft 642 by the rotation of twisted wire machine 645, make rising of the 2nd rotating shaft 642 safer, and rising of the 2nd rotating shaft 642 just can be poured into row operation by a workman, save human cost.
In order to prevent guide deflection sheave 64 from blocking, in described framework 641, tail rod 62 and reverse-flighted screw 63 are also provided with the 3rd oil hole 648 through place, and in order to prevent the 3rd oil hole 648 to be damaged, described 3rd oil hole 648 side is arranged with the 2nd protection gear ring 649.
Owing to the 2nd rotating shaft 642 weight is very big, just in case falling down to be pressed onto people can be very dangerous, therefore described framework 641 is provided with groove 6411 with described 2nd rotating shaft 642 upper-end contact place, described 2nd rotating shaft 641 upper end is provided with elasticity part 6412, described elasticity part 6412 is connected with moving mass 6413, described moving mass 6413 coordinates with described groove 6411, when described moving mass 6413 is positioned at described groove 6411, the elastic force direction that described moving mass 6413 is subject to elasticity part 6412 is downward, in the present embodiment, described elasticity part 6412 is spring, described elasticity part 6412 is arranged at above described moving mass 6413. in order to facilitate rising of the 2nd rotating shaft 642 to fall to operate, described suspension ring 646 are arranged at above described moving mass 6413, rotate twisted wire machine 645 like this when the 2nd rotating shaft 642 needs to fall down and moving mass 6413 can be pulled out groove 6411, facilitate the 2nd rotating shaft 642 to fall down.
Generally all adopt chain drive to carry out transmission of power between row's rope device 6 and the first rotating shaft 4, and traditional sprocket wheel 65 is generally be fixed on main drum 41, arrange rope device 6 every time when needing main drum 41 to rotate and just can be provided power, this mainly mates mutually with working order when main drum 41 rope closing, and when putting rope, general orientation wheel 64 to be moved back on the most limit of reverse-flighted screw 63, because the speed putting rope very soon and also can not make hawser turmoil, so not needing by three-way rope hole 644. And guide deflection sheave 64 is moved back to this manipulation require main drum 41 on the most limit of reverse-flighted screw 63 and rotates together, this certain trouble that operates. Being fixed in described first rotating shaft 4 by sprocket wheel 65 by key now, such main drum 41 does not rotate and guide deflection sheave 64 also can be made to move so that main drum 41 put rope before operation become convenient.
Owing to the power between the first rotating shaft 4 and reverse-flighted screw 63 is by chain gear, and may block between chain and sprocket wheel 65 and damage into foreign matter, also the health of workman may be clamped, therefore described chain and sprocket wheel 65 arranged outside have chain wheel cover 66, described chain wheel cover 66 is generally by two pieces of symmetrical half chain wheel cover 66 split welding when processing, and then it is fixed in the 2nd wall stand 13, and it is very thin at the edge that chain wheel cover 66 welds, it is difficult to chain wheel cover 66 is directed at and is welded, generally needs many people compounding practice. in the present embodiment, the described chain wheel cover 66 of the half cooperatively interacted is provided with chute 661, described in two, chute 661 cooperatively interacts, slotting sheet 662 it is inserted with in described chute 661, wait so when mounted and the chain wheel cover 66 of two half is directed at, then it is smooth for inserting the laminating that described slotting sheet 662 can ensure described in two half between chain wheel cover 66 in chute 661, and the two ends of chain wheel cover 66 are provided with flange 663 described in two half, described flange 663 is provided with fourth hole, it is bolted between described flange 663, also bolt is adopted to fix between described slotting sheet 662 and described chain wheel cover 66.
