Abstract
The utility model discloses an upper frame structure for an excavator, which is a component on the excavator and belongs to the field of engineering machinery. The defect that the upper frame of the excavator in the prior art cannot meet the requirements of small and medium-size excavators is overcome. The upper frame consists of a left frame, a main frame and a right frame, wherein one side of the left frame and one side of the right frame connected with the main frame are provided with a reinforced structure C and a reinforced structure D respectively; a main beam of the main frame adopts a single-plate structure; the reinforced structure C and the reinforced structure D are made of angle iron sections or plate molding angle iron; and the left frame and the right frame form an enclosed frame structure respectively. The upper frame is mainly used on small and medium-size excavators.
Description
Technical field
The utility model is a kind of parts on the excavator, belongs to engineering machinery field, specifically, relates in particular to the upper frame of excavator.
Background technology
Upper frame is the mounting platform of each main components and parts of excavator, and its supporting capacity and rigidity require high, and at present, the upper frame of excavator generally adopts T shape main beam structure.T shape girder has good intensity and rigidity, but its physical dimension is big, seriously restricts the layout of motor, and is for medium and small excavator, more obvious.Now, also there is not a kind of upper frame that is more suitable for medium and small excavator.
Summary of the invention
The purpose of this utility model provides a kind of upper frame of excavator, can not adapt to the defective that medium and small excavator requires with the upper frame that solves excavator in the prior art.
The utility model is realized by the following technical solutions: a kind of upper frame of excavator, to form by left frame, body frame and right frame three parts, and left frame, right frame are connected a side and are respectively equipped with reinforcement C and reinforcement D with body frame; The girder of body frame adopts single plate structure, and described reinforcement C and reinforcement D adopt angle steel section bar or plate forming angle steel.
Left side frame and right frame form the frame construction of sealing separately at last.
Compared with prior art, the beneficial effects of the utility model are, can effectively reduce the physical dimension of girder, make things convenient for distribution engine, left and right reinforcement makes left frame, right frame form the frame construction of sealing, improve manufacture craft, solved the problem that gross distortion appears in past left frame, right frame in manufacturing process easily.

Among the figure: 1. right frame, 2. body frame, 3. left frame, 4. reinforcement C, 5. body frame girder, 6. reinforcement D.
The specific embodiment
A kind of upper frame of excavator is made up of left frame 3, body frame 2 and right frame 1 three parts, and left frame 3, right frame 1 are connected a side and are respectively equipped with reinforcement C4 and reinforcement D6 with body frame 2; The girder 5 of body frame 2 adopts single plate structure, and described reinforcement C4 and reinforcement D6 adopt angle steel section bar or plate forming angle steel; The frame construction of left side frame 3 and 1 each the self-forming sealing of right frame.
The utility model essential implementation is to select suitable body frame girder 5 sheet metal thicknesses and reinforcement C4, reinforcement D6 section bar specification or sheet forming thickness.After determining these two, organize the welding of left frame 3, body frame 2, right frame 1 parts respectively, and finish the machine of body frame 2, then three's welding is formed upper frame.
Claims (2)
