Abstract
The utility model belongs to the field of engineering machinery, and discloses a front and rear beam connecting structure of a front frame of a road roller. The front frame is formed by connecting a front beam and a rear beam through an articulated rack; the front beam consists of a front beam plugging plate (1), a front beam cover plate (2) and a front beam bent plate (3); the front beam bent plate (3) is rectangular, and two ends of the front beam bent plate (3) are connected with the front beam plugging plate (1) and the front beam cover plate (2) by lap welding respectively; the rear beam consists of a rear beam plugging plate (4), a rear beam cover plate (5) and a rear beam bent plate (6); and the rear beam bent plate (6) is rectangular, one end of the lap welding position of two ends of the rear beam bent plate (6) is connected with the rear beam plugging plate (4) by lap welding, and the other end of the rear beam bent plate (6) is connected with the rear beam cover plate (5) by lap welding. The front and rear beam structures of the whole front frame are not easy to deform and have low residual stress so as to increase the strength and the firmness of the front frame.
Description
Technical field
The utility model belongs to engineering machinery field, relates in particular to a kind of forward and backward beam syndeton of road roller front frame.
Background technology
The making of the forward and backward girder construction of road roller front frame is the important step that the engineering machinery structural member is made, and whether its design is reasonable, directly has influence on the performance of road roller, and security reliability.Because the member shaped design of the front-axle beam of front frame and the back rest requires very high in the past; Adopt welding structure mostly, and postwelding is also wanted polishing welding seams, the very difficult assurance of weld strength.
Summary of the invention
The purpose of this utility model provides a kind of forward and backward beam syndeton of road roller front frame, increases the intensity and the fastness of front frame.
For achieving the above object, the utility model adopts following technical scheme:
A kind of forward and backward beam syndeton of road roller front frame, described front frame is connected and composed by the body cradle and the back rest by front-axle beam; Described front-axle beam is made of front-axle beam closure plate, front-axle beam cover plate, front-axle beam bent plate, and described front-axle beam bent plate is rectangular, and the two ends of front-axle beam bent plate are connected with front-axle beam closure plate, the joint welding of front-axle beam cover plate respectively; The described back rest is made of back rest closure plate, back rest cover plate, back rest bent plate, and described back rest bent plate is rectangular, and weld one end at back rest bent plate two ends is connected with the joint welding of back rest closure plate, and the other end is connected with the joint welding of back rest cover plate.
The forward and backward beam syndeton of a kind of road roller front frame that the utility model proposes, the bent plate two ends of front-axle beam are connected with closure plate, cover plate joint welding respectively; One end of back rest bent plate is connected with the closure plate joint welding, and the other end is connected with the cover plate joint welding.The forward and backward girder construction of whole front frame is not yielding and residual stress is little, has increased the intensity and the fastness of front frame.

Fig. 1 is the schematic diagram of front-axle beam syndeton.
Fig. 2 is the lateral view of Fig. 1.
Fig. 3 is the schematic diagram of front-axle beam syndeton.
Fig. 4 is the lateral view of Fig. 3.
Among the figure: 1, front-axle beam closure plate, 2, the front-axle beam cover plate, 3, the front-axle beam bent plate, 4, back rest closure plate, 5, back rest cover plate, 6, back rest bent plate.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
A kind of front-axle beam of road roller front frame, back rest syndeton, described front frame is connected and composed by the body cradle and the back rest by front-axle beam; As shown in Figure 1, 2, described front-axle beam is made of front-axle beam closure plate 1, front-axle beam cover plate 2, front-axle beam bent plate 3, and described front-axle beam bent plate 3 is rectangular, and the two ends of front-axle beam bent plate 3 are connected with front-axle beam closure plate 1,2 joint welding of front-axle beam cover plate respectively; Shown in Fig. 3,4, the described back rest is made of back rest closure plate 4, back rest cover plate 5, back rest bent plate 6, and described back rest bent plate 6 is rectangular, and weld one end at back rest bent plate 6 two ends is connected with 4 joint welding of back rest closure plate, and the other end is connected with 5 joint welding of back rest cover plate.
