Abstract
The utility model discloses a slewing support mounting seat for a lower frame of a construction machine, which belongs to the field of support mounting seats and comprises a mounting seat upper plate, a circular support ring at the lower end of the mounting seat upper plate, a mounting seat bottom plate at the lower end of the circular support ring and holes uniformly distributed on the mounting seat upper plate. The upper end of the circular support ring is welded at the mounting seat upper plate, and the lower end is welded at the mounting seat bottom plate to form a whole; a slewing support mounting face is arranged on the mounting seat upper plate, and the holes are threaded holes; the utility model has the beneficial effects that the mounting seat reduces the defect that welding quality can not be perfectly guaranteed, saves materials, has a simple structure and better stability, simplifies fabrication of parts, and is safe and convenient to assemble, and the gravity center of the entire machine is lower.
Description
Technical field
The utility model relates to a kind of supporting mount pad, specifically is vehicle frame pivoting support mount pad under a kind of engineering machinery, belongs to supporting mount pad field.
Background technology
Use pivoting support to connect getting on the bus of some engineering machinery with getting off to be connected at present; Fixing to realize getting off, get on the bus and the equipment part can realize 360 degree rotations, so that operation task; Like engineering machinery such as excavator, cranes; Because this kind machinery is got on the bus big with equipment part weight, particularly in real work, require very highly to the connection of pivoting support on getting off is fixing, the requirement of strength of this frame pivoting support mount pad that just requires to get off is very high.Like Fig. 3 and shown in Figure 4, the design of pivoting support mount pad in the past generally is by processing after the steel plate welding or form through forging welding processing, supporting on the annulus 2 and be welded with stiffener 6; So not only welding capacity is big, and welding quality can not guarantee fully, and expends a lot of materials; Labour intensity is bigger; And the height of mount pad is improved, thus should the overall upper shift of gravity center of machinery, and stability is bad.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides vehicle frame pivoting support mount pad under a kind of engineering machinery, reduces the defective that welding quality can not guarantee fully, can make moving down of the overall center of gravity of machinery simultaneously again, makes machinery more stable.
To achieve these goals, the technical scheme that the utility model adopts is: comprise the mount pad upper plate, and the support annulus of mount pad upper plate lower end, the mount pad base plate of support annulus lower end is distributed on the hole on the mount pad upper plate.
Further, support annulus upper end and the welding of mount pad upper plate, lower end and the welding of mount pad base plate are integrally formed.
Further, offer the pivoting support installed surface on the mount pad upper plate.
Further, the hole is a screwed hole.
This device is after other sheet material welding, only to need the upper surface through installation and processing seat upper plate than steel plate with one, forms the pivoting support installed surface and screwed hole is installed, and can realize installing and fixing of pivoting support.
The beneficial effect of the utility model is: reduce the defective that welding quality can not guarantee fully, save material, simple in structure, the parts simplified in manufacture assembles up safe ready, and the overall center of gravity of machinery is low, and stability is better.

Fig. 1 is the utility model structural representation
Fig. 2 is the local enlarged diagram of pivoting support installed surface
Fig. 3 is existing pivoting support mount pad forging welded structure figure
Fig. 4 is existing pivoting support mount pad steel plateelement welded structure figure
Among the figure: 1, mount pad upper plate, 2, support annulus, 3, the mount pad base plate, 4, the pivoting support installed surface, 5, the hole, 6, stiffener.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2, vehicle frame pivoting support mount pad comprises mount pad upper plate 1 under a kind of engineering machinery, the support annulus 2 of mount pad upper plate 1 lower end, and the mount pad base plate 3 of support annulus 2 lower ends is distributed on the hole 5 on the mount pad upper plate 1; Support annulus 2 upper ends and 1 welding of mount pad upper plate, lower end and 3 welding of mount pad base plate are integrally formed; Offer pivoting support installed surface 4 on the mount pad upper plate 1; Hole 5 is a screwed hole.
Implementation process: when on excavator, using, mount pad upper plate 1, support annulus 2 and mount pad base plate 3 are welded into one, and intensity is guaranteed.Pivoting support is directly installed on the pivoting support installed surface 4, is fixed on pivoting support on the screwed hole 5 with bolt, can realize installing and fixing of pivoting support.
