Abstract
The invention relates to a wear-resisting improvement structure of an excavator bucket. According to the wear-resisting improvement structure disclosed by the invention, a side plate and a big arc plate are connected by a transition bending plate, by utilizing the integrality of the transition bending plate, quick damage to a corner position of a traditional bucket due to stress concentration can be avoided, the welding position of the traditional bucket is changed, a welding seam is hidden by utilizing a unique lapping structure, and the strength of the welding position is increased; meanwhile, a wear-resisting steel plate can be very easy for covering the outer part of the welding seam, the functions of wear resistance and abrasion resistance are further obtained, a traditional structure is effectively improved, and the service life of the excavator bucket is greatly prolonged; meanwhile, the structure is simple, thus the abrasion can be reduced even the wear-resisting steel plate is not arranged at the outer part of the welding seam under a light-load excavation occasion, the structure is simple, the improvement cost is low, and a very good practice effect is obtained since the wear-resisting improvement structure is implemented.
Description
Technical field
The present invention relates to excavation machinery, particularly the wear-resisting structure-improved of a kind of excavator-type shovel clamshell excavator.
Background technology
Excavator-type shovel clamshell excavator is the important composition parts of excavator, it is one of topmost workpiece of digging operation, even directly determine the power that excavator excavates work capacity, it is generally enclosed by a large arc plate and two blocks of side plates and is connected into a semi-enclosed bucket, when digging operation, the long-term bump contact with material is all needed with the lateral surface of biside plate bottom the large arc plate of bucket, and it is different owing to excavating material property, intensity is different, therefore, this work plane is subject to the wearing and tearing of material for a long time, become the easily worn part on bucket, the solution of its wearing and tearing is always by being paid close attention in the industry, people have thought that a lot of method improves the wearing and tearing at large arc plate place, the large arc plate thickness of such as common increase, increase and paste wear-resisting steel plate, extrados sets up the hole etc. that gets stuck, these measures substantially increase the life-span of bucket, but, Long-Time Service gets off, people ignore a crucial problem, bucket biside plate 10 is all the two sides adopting welding manner to be welded on large arc plate 20 usually, and corner parts, because stress is concentrated, the position that frictional force is larger often, and weld seam itself is more frayed, therefore, generally for protection weld seam, also in order to good welding, side plate 10 will give prominence to a large arc plate 20 bottom surface part, this just defines a little angle at the edge of bucket, although outstanding side plate 10 edge butt welding is sewed with protection to a certain degree, but thoroughly do not solve weld seam to concentrate in edge frictional force, still be more easily worn, and when large arc plate 20 pastes wear-resisting steel plate, this part is usual also not easily protected, often leave gap at edge, this increases the frictional force at this position on the contrary, in view of this, the present inventor for a long time, by observing, in conjunction with a large amount of practices, have found a simple and easy easy structure-improved, thoroughly solve the problem.
Summary of the invention
Object of the present invention, is the wear-resisting structure-improved providing a kind of excavator-type shovel clamshell excavator, by simple structural improvement, improves the excavator life-span, the damageable zone on available protecting excavator.
In order to reach above-mentioned purpose, solution of the present invention is:
A wear-resisting structure-improved for excavator-type shovel clamshell excavator, primarily of large arc plate and side plate composition, described large arc plate is connected by a transition bent plate with side sheet room.
In order to reduce welding sequence, described transition bent plate and side plate one-body molded, its side welds with large arc plate.
Described transition bent plate and large arc plate welding edge form a L shape structure, and large arc plate corresponding position forms an inverted L shape structure and the joining of transition bent plate.
In order to avoid bottom region easy to wear, described transition bent plate and large arc plate one-body molded, its side and plate-side plate welding.
Described transition bent plate and plate-side plate welding limit form a L shape structure, and side plate corresponding position forms an inverted L shape structure and the joining of transition bent plate.
Described transition bent plate weld seam covers wear-resisting steel plate outward.
Described transition bent plate thickness is greater than side plate thickness.
Described transition bent plate lateral surface is arc surface.
The enforcement of the present invention program, by transition bent plate connecting lateral plate and large arc plate, utilize the globality of transition bent plate, avoid traditional bucket in arm of angle position due to the Rapid Damage that extending stress band comes, change the welding position of traditional bucket, unique bridging arrangement is utilized to hide weld seam, increase the intensity of welding position, simultaneously, also make to be easy to outside weld seam cover wear-resisting steel plate, play the effect of abrasionproof damage tolerant further, effectively improve traditional structure, substantially prolongs the application life of bucket, simultaneously, because structure is simple, under the excavation occasion of some light loads, wear-resisting steel plate is covered, also wearing and tearing can be effectively reduced, structure is simple, improvement cost is low, since enforcement, achieve good practice effect.

Detailed description of the invention
Below in conjunction with Fig. 3 to Fig. 5, the invention will be further described:
A wear-resisting structure-improved for excavator-type shovel clamshell excavator, forms primarily of large arc plate 20 and side plate 10, and described large arc plate 20 is connected by a transition bent plate 30 with between side plate 10.Transition bent plate 30 can select with side plate 10 one-body molded (as Fig. 4), or one-body molded with large arc plate 20 (as Fig. 3), and opposite side implements welding, also can separately shaping (as Fig. 5), and its side welds with large arc plate 20 and side plate 10 respectively.Meanwhile, consider the simplification of the technique in casting process, transition bent plate 30 can be only a section the most easy to wear with isoelectric membrane in bucket, and remainder still welds with welding manner by the structure of traditional structure latus inframedium 10 with large arc plate 20.In the present embodiment, in order to protect welding position further, increase weld strength and firmness, transition bent plate 30 welding edge is formed a L shape structure, and large arc plate 20 or side plate 10 corresponding position form an inverted L shape structure and transition bent plate 30 joining.Outside weld seam position, can select to cover wear-resisting steel plate 40.
Further again, because corner location easily forms stressed concentration zones, therefore, transition bent plate 30 lateral surface can be molded into arc surface, to reduce its frictional resistance, certainly, as position easy to wear, its thickness, also needs the thickness being greater than side plate or large arc plate, to strengthen the abrasion resistant effect at position herein.
Above, be specific embodiments of the invention, the restriction not to protection scope of the present invention.All equivalent variations done according to the mentality of designing of this case, all should fall into the protection domain of this case.
