Abstract
The utility model relates to a U-shaped girder structure capable of enhancing strength of a platform, which is used for small and medium tonnage engineering machinery. The girder structure comprises a base plate and a cover plate. A left vertical plate and a right vertical plate are disposed between the base plate and the cover plate to form I-shaped structures. Tail plates are connected to tails of the I-shaped structures and a left front beam, a left side beam, a right front beam and a right side beam are connected with front ends and two sides of the I-shaped structures respectively to form a box type frame. The U-shaped girder is disposed between the base plate and the cover plate, and bending plates are mounted between the tail plates and the left side beam and the tail plates and the right side beam respectively. The U-shaped girder structure has the advantages that the whole structure is an integral box type frame and compact in structure, planeness of the platform surface is guaranteed, the U-shaped girder structure is higher in bearing strength compared with general L-shaped or three section tailor welded girder in traditional platform design according to different working conditions, simpler in structure and better in processing property, and plays an important role in the platform design.
Description
Technical field
The utility model relates to a kind of U type main beam structure that medium and small tonnage engineering machinery improves platform intensity that is used for.
Background technique
At present, working platform is as the important component part of engineering machinery structure, and the intensity of its structure and structure will directly have influence on the rigidity and the reliability of complete machine structure.General Platform Structure Design adopts common L type or three joint welding girders, is facing under the various different operating modes, and its bearing strength, performance are all influenced easily.
Summary of the invention
The purpose of the utility model is exactly to the deficiency that exists in the above-mentioned prior art, provides a kind of structural strength high, simple in structure, the engineering machinery platform U type main beam structure of reliable performance.Its technological scheme is following:
It comprises base plate and cover plate; Left riser and right riser are set between base plate and cover plate form I-shaped structure; Its key technology is to connect tailgate at the I-shaped structure afterbody; Connect left front beam, left side beam, right front beam, the right beam respectively at the front end of I-shaped structure and dual-side and form boxed frame, U type girder is set between base plate and cover plate, between tailgate and left side beam, the right beam, assemble respectively and be connected bent plate.
Compared with prior art the utlity model has following advantage:
1, the utility model total forms a boxed frame, forms integral body, compact structure; Can guarantee the planeness of platform surface; In the face of under the various different operating modes, U type main beam structure is higher than the intensity that the common L type that adopts in the general Platform Structure Design or three joint welding girders can carry, and structure is simpler; Manufacturability is better, in platform design, plays an important role.
2, base plate, cover plate, left riser, right riser are whole moulding, avoid splicing the stress that brings and concentrate factors such as weld defects; Take on the weight of the right and left beam when miscellaneous part is installed by U type girder, be not easy distortion during welding and stay.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A view;
Fig. 3 is Figure 1B-B view.
Embodiment:
Like Fig. 1-shown in Figure 3, the utility model comprises base plate 3 and cover plate 4, left riser 10 is set between base plate 3 and cover plate 4 forms I-shaped structures with right riser 11.Its key technology is that said base plate 3, cover plate 4, left riser 10, right riser 11 4 block plates are whole moulding, does not have splicing, and the stress that adopts whole moulding to avoid splicing to bring is concentrated, factors such as weld defects.Connect tailgate 7 at the I-shaped structure afterbody and form middle frame; Connect left front beam 9, left side beam 8, right front beam 1, the right beam 2 respectively at the front end of I-shaped structure and dual-side and form boxed frames; U type girder 5 is set between base plate 3 and cover plate 4; Bear the weight of the right and left beam when miscellaneous part is installed by U type girder 5, be not easy distortion during welding and stay, between tailgate 7 and left side beam 8, the right beam 2, assemble respectively and be connected bent plate 6.
