Abstract
The utility model discloses an excavator, comprising an excavator body, a movable arm arranged in front end of the body, and a balance weight arranged at a rear end of the body to balance, wherein the balance weight is made of cast iron in integral solid structure, the density of the cast iron is not less than 7.0 t/cu.m. The excavator uses an integral solid cast iron structure and uses the high density of the cast iron, so that the cast iron balance weight not only can meet the requirement of a large-scale excavator to the balance weight, but also the volume of the balance weight is greatly reduced as well as the space is saved; meanwhile, since the cast iron is easy to cast into a model, the excavator is easy to manufacture; after being scrapped, the cast iron balance weight can be recycled; therefore, the excavator is economic and environmentally friendly.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of excavation mining equipment.
Background technology
Excavator is the large-scale excavating equipment that is widely used in mine, tunnel, building site etc., relies on its good working performance and higher operating efficiency to enjoy the people parent to look at.Excavator in order to guarantee the balance of excavator, must be installed the excavator counterweight because front end has swing arm to excavate hand at the excavator afterbody.What existing excavator counterweight adopted is body structure, fixedly installs a casing at the excavator afterbody, adorns scrap iron, stone, concrete etc. then in casing, to increase the weight of counterweight.Along with the high efficiency requirement of modern project operation, large excavator is arisen at the historic moment, so the weight of excavator counterweight also will increase, and could satisfy the balance requirement of large excavator.In order to satisfy the requirement of large excavator to counterweight weight, the volume of existing excavator counterweight is increasing, not only takes up room, and influences attractive in appearance; And usually can't satisfy the weight requirement; bring certain difficulty to excavator manufacturing and use; in addition; particularly when concrete method is packed in the employing of excavator ballast box into; owing to become one in casing after the concrete setting; ballast box also can't continue to recycle when excavator is scrapped, and has caused the waste of resource.
At above-mentioned deficiency, need to explore a kind of new excavator, especially counterweight is carried out improved excavator, not only can satisfy the requirement of large excavator, but also reduce the counterweight volume greatly counterweight weight, generous attractive in appearance, and also easy to assembly, economic environmental protection.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of new excavator, not only can satisfy the requirement of large excavator to counterweight weight, but also reduces the counterweight volume greatly, and is generous attractive in appearance, and easy to assembly, economic environmental protection.
The purpose of this utility model is achieved through the following technical solutions: a kind of excavator comprises car body, is arranged at the swing arm of car body front end and is arranged at the counterweight that the car body rear end is used for balance that described counterweight is the one solid construction, and is not less than 7.0t/m by density
3Cast iron materials make.
Further, described counterweight is provided with the installing hole of distribution triangular in shape, and car body is provided with the screwed hole corresponding with installing hole, and counterweight is connected by the bolt of passing installing hole and be fixed on the car body with car body;
Further, described counterweight is a circular arc along the lateral cross section of car body.
The beneficial effects of the utility model: excavator of the present utility model comprises car body, is arranged at the swing arm of car body front end and is arranged at the counterweight that the car body rear end is used for balance that described counterweight is the one solid construction, and is not less than 7.0t/m by density
3Cast iron materials make.Because excavator of the present utility model adopts the solid cast iron structure of one, utilized the higher characteristics of density of cast iron, make gray iron counterweight not only can satisfy the demand of large excavator, and reduced the volume of counterweight, conserve space greatly counterweight weight; Also utilize cast iron to be easy to the characteristic of casting simultaneously, easily manufactured; Installing hole is set on the integrative-structure, and convenient for assembly, when scrapping, gray iron counterweight can also be recycled, economic environmental protection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the outline drawing of counterweight in the utility model.
The specific embodiment
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is the outline drawing of counterweight in the utility model.As shown in the figure: excavator of the present utility model comprises car body 1, is arranged at the swing arm 2 of car body front end and is arranged at the counterweight 3 that the car body rear end is used for balance that described counterweight 3 is the one solid construction, and is not less than 7.0t/m by density
3Cast iron materials make.Excavator of the present utility model adopts the solid cast iron structure of one, has utilized the higher characteristics of density of cast iron, makes gray iron counterweight not only can satisfy the demand of large excavator to counterweight weight, and has reduced the volume of counterweight, conserve space greatly; Also utilize cast iron to be easy to the characteristic of casting simultaneously, easily manufactured.
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is the outline drawing of counterweight in the utility model.As shown in the figure: excavator of the present utility model comprises car body 1, is arranged at the swing arm 2 of car body front end and is arranged at the counterweight 3 that the car body rear end is used for balance that described counterweight 3 is the one solid construction, and is not less than 7.0t/m by density
3Cast iron materials make.Excavator of the present utility model adopts the solid cast iron structure of one, has utilized the higher characteristics of density of cast iron, makes gray iron counterweight not only can satisfy the demand of large excavator to counterweight weight, and has reduced the volume of counterweight, conserve space greatly; Also utilize cast iron to be easy to the characteristic of casting simultaneously, easily manufactured.
In the present embodiment, described counterweight 3 is a circular arc along the lateral cross section of car body 1.Specifically, the installed surface of counterweight (with the face of excavator applying) is a plane structure, and the face relative with installed surface is the face of cylinder, and this shape not only can satisfy the requirement to counterweight symmetric shape and volume, and is that the excavator profile is more elegant in appearance.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
