For achieving the above object, the utility model adopts following technical scheme: a kind of underwater steel wire rope cable synchronous device, be processed with the identical steel wire rope groove in footpath, the end on the reel both sides, the reel two ends are by bearing support, also be processed with the cable grooving at the reel middle part, drum shaft hollow and prolongation at one end become the hollow spindle nose, and integrated ring assembly is housed on this hollow spindle nose, carbon brush is fixed on the trash frame and with integrated ring and joins, and has an aperture to communicate with the hollow bulb of drum shaft at the reel middle part.

For cable and the steel rope middle footpath on reel is consistent, be processed with step at the reel middle part, make directly to be higher than footpath at the bottom of the steel wire rope groove at the bottom of the cable grooving, its diff-H is the semidiameter of steel rope and cable.

For make cable when hoisting unlikely unrest around, on the trash frame at drum cable grooving place, be provided with a rope guide, it comprises two parallel fixed arms that are hinged on the frame, each fixed arm middle and upper part is hinged with a clamping arm, clamping arm is connected with frame by connecting spring, there are cylinder two ends to be articulated in two clamping arm lower ends respectively, between two fixed arm lower ends, a slide bar is housed, leading sheave is housed on the slide bar, in two fixed arm lower ends the one spacing bar that blocks is housed also, the distance between pulley and the position-limited lever is a bit larger tham cable size.

For guaranteeing the intensity of two fixed arms, between two fixed arm tops, also be provided with a stirrup.

After adopting such scheme, because steel wire rope groove and cable grooving are arranged on the same reel, and wherein the footpath is consistent on being wound on reel the time with cable for steel rope, so just can make hoisting and descend and reaching synchronous fully of steel rope and cable, efficiently solve the stationary problem of trash steel rope and cable, for the large-sized deep water sewage disposal apparatus provides the failure-free motivational guarantee.The utility model has prolonged deep sea cable service life effectively, and makes it safe and reliable.The utility model also can extensively apply to the occasion that hydroelectric dam roof door formula hoisting crane, crane in bridge type etc. need band hydraulic pressure slusher and hydraulic automatic grabbing beam except that can be applicable to trash.
