Description
Technical field
The invention belongs to lifting, Transport Machinery technical field, particularly bulk cargo harbour unloads bridge-type grab ship unloader peculiar to vessel.
Background technology
Grab bucket ship unloader is little because of its strong adaptability, maintenance workload, is the major equipment of bulk cargo harbour employing both at home and abroad at present.The grab bucket of tradition grab bucket ship unloader is clamshell grab bucket.The deficiency of tradition grab bucket ship unloader is: the crawl of grab bucket is less than relatively, and the crawl of coal clamshell grab bucket can only accomplish about 1.55 (capturing ratio: fully loaded weight of material of grabbing bucket/grab bucket deadweight) than maximum; Tradition grab bucket ship unloader is only applicable to terminal belt machine and is all distributed in ship unloaders across interior, or is all distributed in ship unloaders across outward, can not meet terminal belt machine at ship unloaders across interior and across the outer occasion all having distribution.Therefore, production efficiency is restricted, and current coal grab bucket ship unloader market capacity is maximum is about 2100t/h, and terminal belt machine technique adopts at most 4, and overall distribution in ship unloaders across interior or across outward.
Summary of the invention
The object of the invention is the high productivity grab bucket ship unloader developing a kind of appropriate bands multiple spot distributing device, overcome the deficiency of traditional ship unloaders.
Object of the present invention is achieved through the following technical solutions: be applicable to the grab bucket ship unloader being with multiple spot distributing device, comprise traveling mechanism of the larger traveller, metal construction, grab bucket, hoist/opening and closing and dolly winding system and electric-control system, traveling mechanism of the larger traveller drives the cart wheel of speed reduction gearing drive installation bottom metal construction by electrical motor, ground cart orbit runs, for corner drives; Metal construction is the two girder door frame of A type frame formula, comprises pylon, pull bar, jib, girder, door leg, the grab bucket of door beam walked by grab bucket walking dolly on jib and girder; Electric-control system comprises power taking, power transformation, power supply and PLC control system, it is characterized in that: the top between four door legs of described metal construction is provided with structure platform, for installing multiple spot distributing device; Described grab bucket is scissors grab, the hoisting of scissors grab/opening and closing and grab bucket walking dolly steel cable winding system are that four winding drum drives winding system, four steel ropes of grab bucket are that " one " font is arranged at grab bucket head, " one " word is vertical with grab bucket opening and closing direction, wherein support that steel rope is distributed in outermost both sides for two, two opening and closing steel ropes are distributed in two and support in the middle of steel rope, two steel ropes of two reels in four winding drum Zhong Hai side intersect on jib changed course pulley top, and two steel ropes of two reels in side, land do not intersect in the changed course of girder pulley.
Compared with prior art, the present invention has following beneficial effect:
1, scissors grab center of gravity is low, is not easy belowdecks to topple over, and can exempt driver and repeat contraposition, substantially increase efficiency; Scissors grab closing stroke is short, for 65t grab bucket: scissors are 8m, and clamshell is 15m, can reduce to close the bucket time, improve handling efficiency; Scissors grab captures than large; So improve ship unloaders average operation efficiency, reduce ship unloaders energy consumption;
2, two steel ropes of four winding drum middle front part two reels intersect on changed course pulley top, front end, solve grab bucket and are wound around arrangement difficulty.Four steel ropes of scissors grab are that " one " font is arranged at grab bucket head, and because of structure reason, " one " word is vertical with grab bucket opening and closing direction.HADIM hatch dimension by bulge carrier limits, and is that the Width adapting to cabin excavates needs, the opening and closing direction of generally grabbing bucket be sea-side, land to." one " word of such scissors grab head will vertically sea-side, land to, the pulley rope stretching on grab car is arranged and is also adopted in the same way " one " word.Because hoist/open/close driving device can only be in side in machine house, so adopt two steel ropes of two reels in four winding drum Zhong Hai side to intersect on jib changed course pulley top, two steel ropes of two reels in side, land do not intersect in the changed course of girder pulley, meet grab bucket head steel rope and connect demand.
3, meet the process requirements of harbour multiple spot sub-material, Ke Yitai unloads a ship function to across interior and across carrying out discharging outward.
