Abstract
The invention discloses a kind of locomotive sand box mounting structure, sandbox hangs on below locomotive underframe, the box load bearing component that locomotive underframe is made up of upper cover plate, lower cover, lower back panel, curb girder and draw beam, upper cover plate and lower cover are fixedly connected with curb girder upper and lower end face respectively, lower cover is pressed close to curb girder position and is provided with opening, sandbox is upward through opening, sandbox top is made to fit in upper cover plate, a sidewall of sandbox snaps onto on curb girder, all the other sidewalls of sandbox are close to the edge of opening of lower cover, and curb girder is provided with and adds sand mouth.Sandbox is moved to car body from bogie truck, sandbox weight to the impact of track through bogie truck two be the buffering of spring and the absorption of liquid damper, effectively reduced, improve the dynamic performance of locomotive, reduce wheel-rail impact, improve the safety in operation of express locomotive, reduce the maintenance intensity of railroad bed.Under the prerequisite not tying up space under car, effectively increase sandbox available space, be applicable to the installation of locomotive sand box.
Description
Technical field
The present invention relates to locomotive equipment technical field.
Background technology
In railway locomotive operational process, for preventing the skidding of wheel under sleet weather, locomotive is provided with stucco system and sandbox.Sandbox is normally placed in four angles of bogie truck by current railway locomotive, and sandbox is to be bolted on truck frame mount pad as shown in Figure 1.
Sandbox hangs on bogie truck, and with every platform bogie truck 4 sandboxes, each sandbox effective volume 50 is upgraded to example, and every platform bogie truck sandbox and the nearly 400kg of sand weight, can produce no small impact to track at high speeds.In addition, sandbox is suspended on bogie truck side, and the high-frequency vibration impact produced between wheel track when running at high speed can aggravate the metal fatigue of hold-down bolt and mount pad, easily produces metal fatigue crackle, affects traffic safety.
In recent years along with the needs of railway speed increase, the speed that passenger locomotive runs improves constantly, and the raising of speed then exacerbates the impact of wheel to track, has increased the weight of the burden of line upkeep, has also reduced the travelling comfort of passenger simultaneously.In order to alleviate passenger locomotive two is unsprung weight, being transferred to car body from bogie truck by sandbox is then the effective way that current novel locomotive designs.
Current installation form is directly welded in by sandbox on vehicle body bottom frame load lower cover outward, as shown in Figure 2.This structure sand box just moves on on car body simply, because sand face height is in all the time add below sand mouth, a part of Iinvalid volume can be caused, larger sandbox profile is needed under same volume, space limited under tying up car, under the prerequisite that locomotive overall length is certain, be unfavorable for the placement of bogie truck, larger impact is caused on design.
Summary of the invention
Technical matters solved by the invention is to provide the large locomotive sand box mounting structure of a kind of effective volume.
The technical solution used in the present invention is, locomotive sand box mounting structure, sandbox hangs on below locomotive underframe, the box load bearing component that the end of locomotive underframe is made up of upper cover plate, lower cover, lower back panel, sandbox sidewall, curb girder and draw beam, upper cover plate and lower cover are fixedly connected with curb girder upper and lower end face respectively, lower cover is pressed close to curb girder position and is provided with opening, sandbox is upward through opening, sandbox top is made to fit in upper cover plate, a sidewall of sandbox snaps onto on curb girder, and all the other sidewalls of sandbox are close to the edge of opening of lower cover.
Curb girder is provided with and adds sand mouth.
The sidewall thickness of sandbox is 10mm ~ 12mm, can be used for carrying.
The invention has the beneficial effects as follows, sandbox is moved to car body from bogie truck, sandbox weight to the impact of track through bogie truck two be the buffering of spring and the absorption of liquid damper, effectively reduced, improve the dynamic performance of locomotive, reduce wheel-rail impact, improve the safety in operation of express locomotive, reduce the maintenance intensity of railroad bed.Under the prerequisite not tying up space under car, effectively increase sandbox available space.
Accompanying drawing explanation
Fig. 1 is prior art sandbox installation site.
Fig. 2 is the schematic diagram that sandbox is installed on underframe lower cover.
Fig. 3 is sandbox of the present utility model and underframe installation site graph of a relation.
Fig. 4 is sandbox installation site schematic diagram.
Be labeled as in figure: 11-upper cover plate, 12-lower cover, 13-lower back panel, 14-curb girder, 2-sandbox, 21-adds sand mouth, 22-sandbox sidewall, 3-bogie truck, 51-Iinvalid volume.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Sandbox of the present invention is partly embedded in locomotive underframe end construction, and locomotive underframe end is all generally adopt the box carrying structure be made up of upper cover plate 11, lower cover 12, lower back panel 13, curb girder 14 and draw beam.Utilize the space of this box carrying structure, sandbox body is partly embedded in box-structure, at lower cover 12, opening is set near curb girder 14 place, sandbox 2 is upward through open top below upper cover plate 11, sandbox sidewall and underframe curb girder 14 snapping are integrated, adding sand mouth is placed on curb girder 14, and lower cover 12 withstands on all the other sidewalls of sandbox.The Iinvalid volume produced due to gaza's mouth is most of in the box-structure of end, and add sand mouth higher apart from plane on track, sandbox body can elongate downwards, is easier to the volume expanding sandbox 2.Sandbox 2 is overall comparatively far away apart from bogie truck in addition, can not interfere the swing of bogie truck.What take due to sandbox 2 is underframe end space, has larger extending space, and being conducive to increases sandbox volume.
In order to prevent the intensity destroying underframe end, sandbox shell adopts thick plate structure, and because sandbox sidewall snaps onto on curb girder 14, and lower cover 12 fixes on sandbox sidewall, and sandbox sidewall all participates in the carrying of end construction.Sandbox sidewall is processed by 10 ~ 12mm plate, while the good loading strength of guarantee, has good welding performance.
