Abstract
The invention relates to the technical field of diesel locomotives, in particular to a side bearing hole supporting mechanism of a diesel locomotive underframe. The side bearing hole supporting mechanism comprises a main beam, webs, a bottom plate and a side bearing hole. The webs and the bottom plate are connected to the side portions and bottom of the main beam respectively, the side bearing hole is formed in the bottom plate, the side bearing hole is in a drop shape, and a bearing stand plate, a supporting plate, a supporting ribs, reinforcing ribs and a reinforcing stand plate are arranged in the side bearing hole. The side bearing hole is formed in the position, on a lower cover plate of the main beam, of the bottom plate, a traditional frame loading and stress concentration area is avoided, the hole is designed to be in the drop shape, the hole has more excellent mechanical properties under the same thickness, stress is reduced, and the local safety coefficient is greatly improved. In addition, the size of the side bearing hole is obtained in a parameterization mode, the side bearing hole supporting mechanism is suitable for side bearing design of any frame hole, and great universality is achieved. The supporting plate is welded in a frame formed by combining the bearing stand plate, the webs and the bottom plate, and therefore the overall bearing strength of the side bearing hole is greatly improved, and safety is improved.
Description
Technical field
The present invention relates to technical field of diesel locomotive, especially a kind of diesel locomotive under-carriage side bearing hole supporting mechanism.
Background technology
The diesel locomotive of underframe carrying, its side bearing is generally rubber metal pad, and the many designs of side bearing supporting construction are in chassis frame bottom surface.The design of modern ic locomotive has strict demand to chassis frame height, and increasing locomotive adopts in the punching of vehicle frame main beam bottom surface, allows rubber metal pad part stretch into design in beam, reduces chassis frame height.The general side bearing hole adopting square hole and circular hole two kinds of forms at present, all there is more serious problem of stress concentration in the hole of these two kinds of forms, design usually adopts the method increasing local thickness of slab to solve, but local stress under bad working environments still close to SC service ceiling, safety factor is not high.
Summary of the invention
Excessive in order to overcome existing side bearing hole local stress, the deficiency that safety factor is low, the invention provides a kind of diesel locomotive under-carriage side bearing hole supporting mechanism.
The technical solution adopted for the present invention to solve the technical problems is: a kind of diesel locomotive under-carriage side bearing hole supporting mechanism, comprise girder, web, base plate and side bearing hole, web plate and back plate is connected to sidepiece and the bottom of girder, side bearing hole is opened on base plate, side bearing hole is water-drop-shaped, is provided with supporting riser, stay bearing plate, brace rod, reinforced rib and reinforcement riser in side bearing hole.
According to another embodiment of the invention, comprise supporting riser further and be welded on web plate and back plate, be combined into framework.
According to another embodiment of the invention, comprise stay bearing plate further and be welded in framework, stay bearing plate offers knock hole.
According to another embodiment of the invention, the top that brace rod is vertically connected on stay bearing plate is comprised further.
According to another embodiment of the invention, the sidepiece that reinforced rib is welded on web plate and back plate is comprised further.
According to another embodiment of the invention, comprising reinforcement riser is further bridge like, and be overlapped between two blocks of webs, bridge opening is welded with gusset in bottom.
The invention has the beneficial effects as follows, side bearing hole is opened on the base plate be positioned on girder lower cover, avoid traditional Frame Load and areal of stress concentration, and hole shape is designed to drops, under identical thickness, there is more outstanding mechanical property, reduce stress, substantially increase local binding method, in addition, side bearing hole is of a size of parametrization and obtains, be applicable to the side bearing design of any vehicle frame perforate, there is great commonality.In the framework that stay bearing plate is welded on supporting riser, web plate and back plate combines, be used for supporting side bearing rubber metal pad, knock hole is offered in the middle part of stay bearing plate, be convenient to rubber metal pad location, stay bearing plate there is brace rod, guarantee support strength, reinforced rib is positioned at the elongated area of base plate, be welded on the sidepiece of web plate and back plate, local not unstability when guaranteeing beam stress, strengthens riser and is welded on web and base plate, its arc area also welds one piece of gusset, effect improves opening local stiffness, thus substantially increase the integrated support intensity in side bearing hole, improves safety.
