The specific embodiment
As shown in Fig. 1-6, self-propelled holder rope dolly for bridge-type grab ship unloader of the present utility model, comprise frame system and frame, drive system and traction system, described frame system and frame comprises carrying roller 1, frame 2, road wheel 3, horizontal wheel 4 and inhibiting device 5, carrying roller 1 adopts antifriction-bearing box to avoid steel cable sliding wearing and tearing, described carrying roller 1 is fixed in frame 2, described road wheel 3 and horizontal wheel 4 are fixed on frame 2 bottoms, the quantity of described road wheel 3 and horizontal wheel 4 is four, guarantee four jiaos of smooth runnings of frame, described inhibiting device 5 is located on frame 2 bottoms and guide pulley device 9, accurate controlling run route, described drive system comprises motor 6, reductor 7 and traction steel wire rope reel 8, described motor 6 drives 8 runnings of traction steel wire rope reel, described reductor 7 is located between motor 6 and traction steel wire rope reel 8, described steel rope 10 is comprised of steel rope I 14 and steel rope II 15, described steel rope I 14 and steel rope II 15 are wound around from entering up and down traction steel wire rope reel 8 respectively, meet forward-reverse requirement, motor 6 is controlled and is met working condition requirement by complete machine PLC program, reductor 7 is direct-connected by toothed coupling with traction steel wire rope reel 8, output driving torque, described traction system comprises guide pulley device 9, steel rope 10, fixed terminal 11, adjust turnbuckle 12 and bearing 13, described guide pulley device 9 connects horizontal wheel 4, quadruplet is fixed on dolly, a set of track crossbeam that is fixed on, the tail end of 11 pairs of steel ropes 10 of described fixed terminal is fixed, described fixed terminal 11 connects bearing 13 by adjusting turnbuckle 12, structural arrangement is compact, advantages of simple, cost-saving, be convenient to promote the use of.
The 1800t ship unloaders of specifically take are researched and developed as example:
After former dolly, the maximum suspension of rope length is 38m+26m=64m, if add a self-propelled holder rope dolly 19, when normal discharging, reaches working position 16(apart from land siding track 18 17m places, center).Hang length and reduce to 47m, will make outstanding length under steel cable greatly reduce, approximately can reduce 47%.In the time of will hanging conveyer for emptying warehouse as ship unloaders, holder rope dolly 19 is reached to rest position 17(apart from land siding track 18 2m places, center), main carriage reaches apart from land siding track 18 8m places, center and hangs conveyer for emptying warehouse.
Broken through traditional holder rope dolly 19 drive forms, changed passive traction for driving voluntarily, version change had both met the requirement that traditional form cannot be arranged, had met again large outreach and had avoided the sagging excessive problem of steel rope 10; Two cover steel ropes before and after traction system adopts, the anterior rope traction of the process of advancing, rear portion steel wire tensioning, can guarantee that into same traction steel wire rope reel 8 steel rope 10 linear velocities are consistent owing to having mercy on, guarantee that holder rope dolly 20 can be because the effect of inertia can not at the uniform velocity be advanced, otherwise retreat; The electric acceptor's Electrical Control of drive motor 6 PLC controls, and accepts instruction and can guarantee move or stop at the working condition of appointment, by limit switch, accurately locates and interlock protection; In order to guarantee that haulage cable 10 has certain degree of tension, at two cover fixed terminals 11, be provided with respectively and reconcile turnbuckle 12, by left-right rotary, adjust in good time, simple and practical.
