Abstract
The utility model discloses a kind of excavator, it is characterized in that, this excavator comprises driver's cabin, running gear and excavating gear, revolving dial is provided with between described driver's cabin and running gear, described excavating gear is connected with driver's cabin, described excavating gear comprises rotation swing arm, dipper, scraper bowl and cylinder apparatus, and the side plate thickness on described rotation swing arm is 6.2mm.The excavator that the utility model provides, by rotation arm side plate thickness is increased to 6.2mm, now, by the ameliorative way of this increase stress surface, rotate swing arm and occur that the phenomenon in fracture and crack also reduces greatly, thus make excavator safety and reliability, stability improves, and substantially increases the application life of swing arm, reduces maintenance cost.
Description
Technical field
The present invention relates to engineering machinery field, particularly relate to a kind of excavator.
Background technology
Excavator is that a kind of scraper bowl excavates higher or lower than the material holding machine side, is transported to the self-propelled mining machinery of disposing place unloading.Material mainly soil, coal, silt and the Soil and Rock after pre-pine excavated.In recent years, along with the development of engineering machinery, as the excavator of one of engineering machinery topmost in engineering construction, its security performance, the raising in application life is vital.Current excavator, swing arm often has the phenomenon of fracture, and ratio accounts for about 5%, and when there is the phenomenon in swing arm crack the working time also shorter, part machine just occurred in 1000 hours.Through to fracture and occur the swing arm dissection and analysis in crack, research draws, occur that the reason major part of this phenomenon is arm side plate thickness low LCL, solder side is narrow, thus causes stress surface little and the phenomenon in fracture and crack occurs.
Utility model content
The purpose of this utility model be to provide a kind of safe and reliable, stability is high, and substantially increases the excavator in swing arm application life.
For achieving the above object, the utility model provides following technical scheme:
A kind of excavator, it is characterized in that, this excavator comprises driver's cabin, running gear and excavating gear, revolving dial is provided with between described driver's cabin and running gear, described excavating gear is connected with driver's cabin, described excavating gear comprises rotation swing arm, dipper, scraper bowl and cylinder apparatus, and the side plate thickness on described rotation swing arm is 6.2mm.
Preferred as technique scheme, described cylinder apparatus comprises boom cylinder, bucket arm cylinder and bucket cylinder.
As can be seen from technique scheme, the excavator that the utility model provides, rotation arm side plate thickness is increased to 6.2mm, now, by the ameliorative way of this increase stress surface, rotate swing arm and occur that fracture and the phenomenon in crack also reduce greatly, thus make excavator safety and reliability, stability improves, and substantially increase the application life of swing arm, reduce maintenance cost.
Accompanying drawing explanation
By reference to the accompanying drawings, and by reference to detailed description below, will more easily there is more complete understanding to the utility model and more easily understand its adjoint advantage and feature, wherein:
Fig. 1 is structural representation of the present utility model.
[in figure Reference numeral]:
1-driver's cabin, 2-running gear, 3-revolving dial, 4-rotates swing arm, 5-dipper, 6-scraper bowl, 7-boom cylinder, 8-bucket arm cylinder, 9-bucket cylinder, 10-side plate.
Detailed description of the invention
Make content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certain the utility model is not limited to this specific embodiment, and the general replacement known by those skilled in the art is also encompassed in protection domain of the present utility model.Secondly, the utility model detailed statement that utilized schematic diagram to carry out, when describing the utility model example in detail, for convenience of explanation, schematic diagram, should in this, as the restriction to the utility model type not according to general ratio partial enlargement.
It should be noted that, in following embodiment, utilize the structural representation of Fig. 1 to carry out detailed statement to by a kind of excavator of the utility model.When describing embodiment of the present utility model in detail, for convenience of explanation, each schematic diagram is not according to general scale and carried out partial enlargement and omitted process, therefore, should avoid in this, as to restriction of the present utility model.
As shown in Figure 1, the utility model provides a kind of excavator, this excavator comprises driver's cabin 1, running gear 2 and excavating gear, revolving dial 3 is provided with between driver's cabin 1 and running gear 2, excavating gear is connected with driver's cabin 1, excavating gear comprises rotation swing arm 4, dipper 5, scraper bowl 6 and cylinder apparatus, and side plate 10 thickness rotated on swing arm 4 is 6.2mm.
Concrete, in the present embodiment, cylinder apparatus comprises boom cylinder 7, bucket arm cylinder 8 and bucket cylinder 9.
In sum, the excavator that the utility model provides, by rotation arm side plate thickness is increased to 6.2mm, now, by the ameliorative way of this increase stress surface, rotate swing arm and occur that fracture and the phenomenon in crack also reduce greatly, thus make excavator safety and reliability, stability improves, and substantially increase the application life of swing arm, reduce maintenance cost.
