Abstract
The invention provides a cab design method, a cab and construction machinery. The cab comprises a cab body comprising an inner layer and an outer layer which is made of sheet metal, and the inner layer and the outer layer are stacked and form an accommodating cavity along the contour of the cab. The cab body is arranged as an inner-outer dual layer structure, and the outer layer is made of the sheet metal, so that appearance forming is facilitated; the contour line of the cab is the main force-bearing part normally, and the inner layer and the outer layer form the accommodating cavity along the contour of the cab, so that the bearing capacity of the main force-bearing part is stronger; a central skeleton can be arranged in the accommodating cavity of the cab body if necessary, so that the strength of the entire cab can be guaranteed. Therefore, compared with the prior art, the cab has better overall advantages in terms of entire strength and appearance forming.
Description
Technical field
The present invention relates to Machine Manufacturing Technology, be specifically related to a kind of operator's compartment and method of designing thereof; In addition, the invention still further relates to a kind of construction machinery and equipment with this operator's compartment.
Background technology
Operator's compartment is the important component part of construction machinery and equipment, and its Main Function is to provide safe, comfortable operating environment for chaufeur; Therefore, operator's compartment need to meet certain requirement of strength usually.In addition, people wish that operator's compartment possesses visual effect preferably usually, and therefore, the appearance and modeling of operator's compartment is also one of key factor affected its market sales volume.
At present, operator's compartment commonly used has following two kinds of structures: 1) adopt shaped steel and steel plate overlap joint to form support frame, and then sheet member/sheet metal component is covered on support frame, finally form the main body frame of operator's compartment; 2) adopt multilayer sheet metal component direct splicing to form the main part of cabin framework.The operator's compartment bulk strength that adopts first kind of way to obtain is better, but affected by shaped steel, the form compare difficulty, and in manufacturing process, the level of becoming more meticulous is difficult to guarantee, outside face is done manual work also relatively coarse; Therefore, the appearance and modeling of such operator's compartment is difficult to attract clients usually.In view of the sheet metal component mature production technology, the sheet metal component moulding is changeable, and the common variation in moulding of operator's compartment that adopts the second way to obtain is relatively free, and the surface fine level is higher, and still, this class operator's compartment bulk strength is not high, and its safety is relatively low.
Therefore, how when guaranteeing the operator's compartment bulk strength, for the appearance and modeling of operator's compartment facilitates, be still those skilled in the art's technical matters urgently to be resolved hurrily.
Summary of the invention
In view of this, the present invention proposes a kind of operator's compartment, and compared with prior art, this operator's compartment, when possessing suitable bulk strength, can more conveniently carry out appearance and modeling.And the present invention also proposes a kind of construction machinery and equipment that possesses this operator's compartment.In addition, the present invention also proposes a kind of operator's compartment method of designing.
On the one hand, the present invention proposes a kind of operator's compartment, comprise body shell cab body, described body shell cab body comprises the skin that internal layer and sheet metal component are made, and described internal layer and outer stack adduction form containing cavity along the profile of described operator's compartment.
Further, be provided with center framework in described containing cavity.
Further, described center framework is made by shaped steel or bending plate.
Further, the cross section of described center framework is " work " font or " mouth " font.
Further, the end face of body shell cab body or side are provided with brace panel or strength beam.
Further, be provided with body insulation and/or thermal insulation material between described internal layer and skin.
The operator's compartment that the present invention proposes comprises body shell cab body, and described body shell cab body comprises the skin that internal layer and sheet metal component are made, and described internal layer and outer stack adduction form containing cavity along the profile of described operator's compartment.By body shell cab body being arranged to interior outer double-layer structure, skin is made by sheet metal component, is convenient to appearance and modeling; The force part that the outline line of operator's compartment is normally main, internal layer forms containing cavity with the outer profile along operator's compartment, makes the load-carrying capacity of main force part of operator's compartment stronger, thereby strengthens the intensity of whole operator's compartment.Therefore, compared with prior art, this operator's compartment possessing comprehensive advantage preferably aspect bulk strength and appearance and modeling.
On the other hand, the invention allows for a kind of construction machinery and equipment, comprise the operator's compartment of chassis and above-mentioned any one, described operator's compartment is arranged on described chassis.
By adopting above-mentioned operator's compartment, can effectively guarantee the safety of chaufeur, simultaneously, the aesthetics of this project machinery more easily obtains lifting, thereby is conducive to the Win Clients favor.
Another aspect, the present invention also proposes a kind of operator's compartment method of designing, and described operator's compartment comprises body shell cab body, and described body shell cab body comprises the skin that internal layer and sheet metal component are made, and described internal layer and outer stack adduction form containing cavity along the profile of described operator's compartment; Can determine whether to arrange center framework in containing cavity according to the application operating mode of described operator's compartment.
Further, when in operator's compartment, center framework being set, go out cross section parameter and the material behavior of described center framework optimum according to described application condition calculating, and the center framework that will possess optimum cross section parameter and material behavior is arranged in containing cavity.
Further, when in operator's compartment, center framework being set, selecting the center framework mated most with it according to described application operating mode in default center framework typelib, and selected center framework is arranged in containing cavity.
The operator's compartment method of designing proposed according to the present invention, can obtain the operator's compartment of varying strength to meet the different needs; As relatively simple as operating mode, the dynamic load that operator's compartment is subject to hour, can consider not establish center framework; When operating mode is more complicated, severe, the center framework that intensity and operating mode are complementary can be set in the containing cavity of body shell cab body, strengthen the intensity of whole operator's compartment with this, guarantee that the intensity of operator's compartment meets the applying working condition demand.
