Abstract
The invention discloses a locomotive sand box mounting structure, wherein the sand box is suspended under the chassis of the locomotive; the chassis of the locomotive is a box type bearing component composed of an upper cover plate, a lower cover plate, a rear end plate, a side beam and a draft sill; the upper cover plate and the lower cover plate are fixedly connected with the upper and lower end faces of the side beam, respectively; an opening is formed in a part of the lower cover plate next to the side beam; the sand box penetrates through the opening upwards so that the top of the sand box is fitted to the upper cover plate; one side wall of the sand box is buckled to the side beam, while other side walls of the sand box are closely fitted to the edge of the opening of the lower cover plate; and a sand filling opening is formed in the side beam. The sand box is moved to the locomotive body from a bogie; the impact on the track caused by the weight of the sand box can be effectively reduced as being buffered by two tie springs of the bogie and absorbed by a hydraulic shock absorber; and therefore, the dynamics performance of the locomotive is improved, the impact on the wheel track is reduced, the safety of the locomotive in running is improved and the maintenance strength of the railway subgrade is reduced. The available capacity of the sand box is effectively increased without occupying the space under the locomotive; and as a result, the structure is suitable for mounting the locomotive sand box.
Description
Technical field
The present invention relates to the locomotive equipment technical field
Background technology
In the railway locomotive operational process, for preventing skidding of under sleet weather wheel, be provided with stucco system and sandbox at locomotive.At present railway locomotive normally places sandbox four angles of bogie truck, and sandbox is connected on the truck frame mount pad with bolt as shown in Figure 1.
Sandbox hangs on the bogie truck, and with 4 sandboxes of every bogie truck, each sandbox effective volume 50 is upgraded to example, and every bogie truck sandbox and the nearly 400kg of sand weight can produce no small impact to track under fast state.In addition, sandbox is suspended on the bogie truck side, and the high-frequency vibration impact that produces between wheel track when running at high speed can aggravate the metal fatigue of hold-down bolt and mount pad, easily produces the metal fatigue crackle, affects traffic safety.
Along with the needs of railway speed increase, the speed of passenger locomotive operation improves constantly in recent years, and the raising of speed has then aggravated the impact of wheel to track, has increased the weight of the burden of line upkeep, has also reduced passenger's travelling comfort simultaneously.Be unsprung weight in order to alleviate two of passenger locomotive, it then is an effective way of current novel locomotive design that sandbox is transferred on the car body from bogie truck.
Present installation form is that sandbox directly is welded in outward on the vehicle body bottom frame load lower cover, as shown in Figure 2.This structure sand box just moves on on the car body simply, because being in all the time, sand face height adds below the sand mouth, can cause a part of Iinvalid volume, need larger sandbox profile under the same volume, can tie up space limited under the car, under the certain prerequisite of locomotive overall length, be unfavorable for the placement of bogie truck, design is caused larger impact.
Summary of the invention
Technical matters solved by the invention provides the large locomotive sandbox mounting structure of a kind of effective volume.
The technical solution used in the present invention is, locomotive sandbox mounting structure, sandbox hangs on the locomotive underframe below, the box load bearing component that the end of locomotive underframe is comprised of upper cover plate, lower cover, lower back panel, curb girder and draw beam, upper cover plate is captiveed joint with the curb girder upper and lower end face respectively with lower cover, lower cover is pressed close to the curb girder position and is provided with opening, sandbox is upward through opening, make the sandbox top fit in upper cover plate, a sidewall of sandbox snaps onto on the 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 the 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 on the car body from bogie truck, sandbox weight is the absorption of buffering and the liquid damper of spring to the impact of track through bogie truck two, effectively reduced, improved the dynamic performance of locomotive, reduced wheel-rail impact, improved the safety in operation of express locomotive, reduced the intensity of safeguarding of railroad bed.Under the prerequisite that does not tie up space under the car, effectively increase the sandbox available space.
Description of drawings
Fig. 1 is prior art sandbox installation site.
Fig. 2 is the scheme drawing that sandbox is installed on the underframe lower cover.
Fig. 3 is sandbox of the present invention and underframe installation site graph of a relation.
Fig. 4 is sandbox installation site scheme drawing.
Be labeled as among the figure: the 11-upper cover plate, the 12-lower cover, the 13-lower back panel, the 14-curb girder, 2-sandbox, 21-add the sand mouth, 22-sandbox sidewall, 3-bogie truck, 51-Iinvalid volume.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Sandbox of the present invention partly is embedded in the locomotive underframe end construction, and the locomotive underframe end generally all is to adopt the box carrying structure that is comprised 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, partly be embedded in the sandbox body in the box-structure, near curb girder 14 places opening is set at lower cover 12, sandbox 2 is upward through open top below upper cover plate 11, sandbox sidewall and underframe curb girder 14 snappings are integrated, add the sand mouth and place on the curb girder 14, lower cover 12 withstands on all the other sidewalls of sandbox.Because it is higher that the Iinvalid volume major part that the gaza mouth produces in the box-structure of end, adds sand mouth plane on the track, the sandbox body can elongate downwards, is easier to expand the volume of sandbox 2.Sandbox 2 integral body are far away apart from bogie truck in addition, can not interfere the swing of bogie truck.Because what sandbox 2 took is the underframe end space, has larger extending space, is conducive to increase the sandbox volume.
In order to prevent from destroying the intensity of underframe end, the sandbox shell adopts thick plate structure, because the sandbox sidewall snaps onto on the curb girder 14, and lower cover 12 fixes on the sandbox sidewall, and the sandbox sidewall all participates in the carrying of end construction.The sandbox sidewall is processed by 10 ~ 12mm plate, when guaranteeing good loading strength, has preferably welding performance.
