Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the welded swing frame for the front axle of the wheel excavator comprises an upper rib plate 1 and a lower rib plate 5 which are welded with each other, and a sleeve 2 and a backing plate 3 are arranged in a space formed after the upper rib plate 1 and the lower rib plate 5 are welded.

Further, the upper part of the sleeve 2 is welded with the upper rib plate 1, the lower part of the sleeve 2 is welded with the upper part of the backing plate 3, and the lower part of the backing plate 3 is welded with the lower rib plate 5.

Further, rib plates II 6 are respectively arranged on the front face and the rear face of a space formed after the upper rib plate 1 and the lower rib plate 5 are welded, and the rib plates II 6 are welded with the upper rib plate 1, the lower rib plate 5 and the sleeve 2.

Furthermore, rib plates I4 are welded on the upper surfaces of two sides of the upper rib plate 1.

Furthermore, a rib plate III 7 is welded on the protruding part of the lower rib plate 5, which is used for connecting a steering oil cylinder.

Furthermore, the welded type swing frame is fixedly connected with the axle housing shell through an upper rib plate 1, a lower rib plate 5 and a rib plate I4 which are welded into a whole.

Furthermore, a sliding bearing is arranged in the hole of the sleeve 2, and an inner hole of the sliding bearing is inserted into a swing pin and is connected with the body of the wheel type excavator through the swing pin.

The upper rib plate 1 and the lower rib plate 5 are basic components, and the force of the wheel excavation vehicle body acting on the swing frame is finally transmitted to the axle housing by the two components; the force action point of the wheel digging vehicle body on the swing frame (or on the front axle assembly) is arranged at the lower part of the inner hole of the sleeve 2, and the sleeve 2 is internally provided with a bearing and then is used as a combined component with the wheel digging vehicle body to directly bear the acting force of the wheel digging vehicle body; the base plate 3 directly transmits the acting force on the sleeve 2 to the lower rib plate 5 to play the role of supporting and transmitting; the rib plate 4 is arranged for increasing the rigidity of the swing frame; the rib plates 6 play a role in connecting the upper rib plate 1, the lower rib plate 5 and the sleeve 2 together except for filling the space, so that the force applied to the sleeve 2 is more uniformly transmitted to the upper rib plate 1 and the lower rib plate 5; the rib 7 serves to increase the rigidity of the protruding portion of the lower rib 5.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
