14、ils in general arrangement drawing DQ9912.0ST） consists of bucket-wheel mechanism, super steel structure, boom conveyor, main ladder platform, luffing hydraulic device, portal, support pivot, slew deck, transfer chute, slewing mechanism, limited switch device, detection device, long travel, central

15、lubrication system, power cable reeler device, control cable reeler device, tripper car, impact bracket, ladder platform of tripper car, dust suppression /sprinkling system, electric room, electrical system, operators cabin, nameplate, counterweight assembly, foundational layout, load and so on.Supe

16、r structure of main machine is an integral structure which consists of boom rack, pylon, counterweight boom and front and back bracing , all parts will be connected by pin roll which fixed by block. Head part is bucket-wheel mechanism; back part is counterweight assembly which can adjust the balance

17、 of super structure. Super structure is fixed on slew deck by support pivot, the upper part of the support pivot （bearing body） will be welded with the lower plane of the pylon; the lower part of the support pivot （supporting block） will be welded with the upper plane of the Slew deck. The completed

18、 structure can waggle around the support pivot point, Hydraulic cylinder which lie between slew deck and pylon acts can achieve integral luff of super structure. Slew support bearing is mounted between upper and lower pedestal ring, upper pedestal ring supports the slew deck, and lower pedestal ring

19、 is fixed on the portal. Slew driving device is fixed on the slew deck, and through output axis pinion of slewing reducer, the spur pinion is meshed with big gear ring which is fixed under the bearing of lower pedestal ring, which shall transmit upper structure to rotate around slew center. Pivot of

20、 traveling mechanism is welded with support leg of portal. Since such structure adopts integral machine luff structural type, it has less connecting joints, less services, and high security.Section 2: Detailed structure of unit and operating features1 Bucket-wheel mechanism1.1 StructureBucket-wheel

21、mechanism mainly consists of bucket wheel drive device, ring chute, bucket wheel body, bucket wheel shaft, bucket, sliding chute and guide chute device etc. Bucket wheel drive device consists of motor, gearbox/reducer, block and drive gear etc.; through motor-gearbox transmitted to bucket wheel shaf

22、t. So bucket wheel body can be driven by bucket wheel drive device, and can be carried out reclaiming operation. Total nine buckets with bucket teeth are fixed on bucket wheel body （bucket teeth should be detachable） by pin rolls and pins, Bucket wheel mechanism consists of them. Bucket wheel body is cell less type, in order to
