Problems solved by technology

Since all the main ribs and auxiliary ribs are connected by welding, the welds are prone to sudden changes when transferring stress flow, resulting in excessive concentration of local stress and affecting the strength of the rib structure

Embodiment Construction

[0022] see figure 1 and figure 2 , The vehicle frame slewing support seat structure of the first embodiment of the present invention includes a slewing center seat 110 , a number of first ribs 130 , a number of second ribs 150 and a number of third ribs 170 . The rotary center seat 110 is in the shape of a cone, and the first rib 130 , the second rib 150 and the third rib 170 are fixed in the rotary center seat 110 . The first ribs 130 are radially arranged at intervals around the axis of the rotating center base 110 . The first rib 130 includes a flat main rib 132 and wing plates 134 integrally bent from two ends of the main rib 132 . The wing plate 134 is connected with the inner wall of the rotary center base 110 . There is an arc transition between the wing plate 134 and the main rib 132 , and an obtuse angle between the wing plate 134 and the corresponding main rib 132 . The second rib 150 is fixedly connected to the wing plate 134 of the adjacent first rib 130 by we...

Abstract

The invention discloses a frame and a rotary bearing seat structure thereof. The rotary bearing seat structure of the frame comprises a rotary centre seat, a plurality of first rib plates and a plurality of second rib plates. The first rib plates and the second rib plates are fixed in the rotary centre seat, and the second rib plates are connected with the adjacent first rib plates. The first rib plates are radially disposed at intervals around the rotary centre seat, and each of the first rib plates comprises a main rib plate and wing plates formed by being integrally bent from the both ends of the main rib plate. The swing plates are connected with the inner wall of the rotary centre seat, the swing plates form arc transition with the main rib plate, the second rib plates and the main rib plate form a ring and round as a circular centre opening. Utilizing the technical scheme disclosed by the invention, the abrupt change of stress can be efficiently avoided, thereby preventing influence on the strength of the rotary bearing seat structure of the frame due to too intensive local stress.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a vehicle frame and a structure of a vehicle frame slewing support seat. Background technique [0002] With the development of heavy machinery such as cranes to medium and large tonnages, in order to ensure the lifting performance, it is usually necessary to install welded and fixed ribs on the structure of the slewing bearing seat of the frame to strengthen the force that the slewing ring can bear. However, the structural form of the rib and its position on the structure of the slewing bearing seat of the vehicle frame directly affect the magnitude and distribution of the structural stress of the slewing bearing seat of the vehicle frame. [0003] At present, the common rib structure is mostly radial or grid. Among them, in the radial rib structure, the main ribs are arranged radially, which is basically consistent with the direction of the force. The auxiliary ribs are welded to the ma...
