The specific embodiment
For further understanding technology contents, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
Consult accompanying drawing 1 to Fig. 7.
Embodiment 1
A kind of dredge boat comprises great circle and bucket with novel separate type bucket wheel, and bucket is assemblied on the great circle; Bucket is a separate type, is divided into bucket body and bucket lip, and the bucket lip is located at the top of bucket body.Bucket body with the bucket lip weld together, the bucket lip cutting angle is arranged, the bucket position, lip cutting angle be the bucket shape transition, wall thickness by the 45mm gradual change to 25mm.Bucket lip edge is a cutting blade.Bucket quantity is 12.Be equipped with between bucket and connect the reinforcing rib bar.Bucket and great circle welding assembling are provided with triangle and strengthen gusset before and after bucket root and the great circle weld.
The concrete structure of the utility model, characteristics and process:
1, the bucket wheel design feature of present embodiment:
To former bucket wheel design defect, bucket wheel structure and bucket profile, structure, material etc. are designed:
1) bucket wheel assembly bucket is 12, effectively increases the bucket gap, is convenient to the entering of mud;
2) the bucket profile is removed bucket tooth for being with body open type slightly, increases bucket lip cutting angle and bucket lip cutting blade.Wall thickness is reduced to 45mm by 60mm, increases the bucket lip simultaneously, and the bucket lip adopts the transition of tipping bucket type, wall thickness from the 45mm gradual change to 25mm.
3) bucket has better cutting hardness, toughness and underwater operation abrasion resistance, anti-corrosive properties preferably, and development cost is lower, and bucket body is selected unlike material for use with the bucket lip.1. bucket body is selected 20SiMn for use; 2. the lip that struggles against is selected 35CrNiMo for use.The main position of dredging of cutting is the lip that struggles against, and selects for use 35CrNiMo to improve the hardness and the abrasion resistance of bucket lip, simultaneously in order to reach bonding strength preferably, selects the A132 welding rod that the capping of welding bead is connected operation.
2. the innovative point of present embodiment
1) bucket profile optimization
The bucket wheel assembly is 12 bucket wheels, and bucket is for being with body open type slightly, size 800 * 910 * 1380 (mm), and adjacent bucket body spacing is big, improves monobucket and cuts the mud amount, simultaneously the economical with materials cost.Bucket is long to be 91cm, and reduction bucket wheel cutting moment is offset the excavating resistance that bucket wheel brings because of the increase cutting angle after transforming.
2) bucket body and the design of bucket lip separate type
The bucket body of novel bucket adopts the design of novelty separate type with the bucket lip.Bucket wheel is through long-term operation, and when its bucket lip generation heavy wear extremely can't normally be used, the lip that only needs to struggle against downcut with gas welding, and the bucket lip that more renews gets final product, and need not to change whole bucket.
3) the bucket wheel material is preferred
After bucket had adopted bucket body and bucket lip separate type to design, according to this two parts work characteristics and weldability requirement, design bucket body material was 20SiMn, makes the bucket body material have stronger structural rigidity intensity; The bucket lip then adopts more wear-resisting 35CrNiMo, has so both guaranteed the abrasion resistance of bucket lip, has guaranteed good pliability and welding performance again.
4) energy efficiency design
12 of bucket wheel bucket quantity, diameter are 4.66 meters.The overall weight of bucket wheel alleviates, and reduces raw-material consumption, has good and economic.
3, the process of present embodiment:
1) prepares before the weldering
(1) adopt gas welding to open 45 ° of monolateral double V-grooves bucket body and great circle junction, the groove size is decided by the bucket body wall thickness;
(2) greasy dirt, iron rust, oxide skin and other dirt removal in 10-20mm scope around the groove is clean, influence current stabilization to prevent it, worsen the welding bead outward appearance and generate pore;
(3) welding rod carries out drying and forewarm, dries 1 hour for J506:350 ℃, dries 1-2 hours for A132:350 ℃.
2) welding method
(1) adopt the J506 SMAW that bucket body and great circle are carried out solder joint and fix, it is big that density is wanted, and solder joint is wanted firmly, produces when preventing the large tracts of land welding to be out of shape or bucket body comes off.
(2) great circle up and down with bucket supports with the special-purpose device that tightly rises, in order to avoid the shrinkage stress of postwelding causes integral body or local distortion.
When (3) the bucket body groove welded, two back-to-back operations of welder were welded following one groove behind the intact one deck of per pass groove welding in order, and circulation successively prevents to cause being out of shape the probability increase because the sweating heat that disposable filling causes input increases.
(4) welding bead adopts the CO2 gas shielded arc welding to fill, and wlding adopts 1.2mm JQ.MG50-6 solid welding wire, will pay special attention to the fusion situation of mother metal during bottoming.
(5) capping of welding bead adopts the A132 welding rod to improve the scuff resistance on surface, and when welding, leaves the polishing surplus about 3mm.
