Abstract
The utility model relates to a small screening machine for the full section of a road bed used on electrified railway and mountain railway. Each working mechanism is positioned in central symmetry. The work device dismounted from a ballast girder is a rigidity assembly, and can transfer and move the operating point. The back end of a screen box of the screening machine tilts upwardly by 8-15 DEG; an average slag plate is arranged in the screen box; the bottom of the screen box is provided with a support roller. A drive motor of a backfill mechanism is positioned in a conveyor chain box. A rotary type slope digging mechanism can dig with a tension side.
Description
The utility model relates to the basic device of a kind of railway with the small-sized screen scarifier of road bed full-section, is specially adapted to the railway roadbed cleaning of electrified and mountain route.
Railway ballast is because of the effect of cyclic loading, and the erosion of dust storm, sleet and the railway roadbed forfeiture elasticity that occurs, rises soil or harden, and all can influence the ride comfort and the traffic safety of train operation, quickens the damage of locomotive and circuit.When surpassing 25%, the unclean degree of railway roadbed then needs railway roadbed is carried out full section cleaning, to recover railway roadbed elasticity.Electrified circuit and mountain route are little because of line circle profile, roadbed is narrow and radius of curvature is little, are difficult to adopt big-and-middle-sized circuit screen scarifier to carry out operation.In addition, closed-loop and carry out sorting operation is not the specific (special) requirements to small-sized screen scarifier yet.Not closed-loop and the small-sized screen scarifier that carries out operation adopted that monolateral or bilateral chain type is excavated more, the working method of the walking of curb chain link formula, the centrifugal cleaning of curb.The subject matter that existing small-sized screen scarifier exists is: be not suitable for little electrified circuit of line circle and small radius mountain route; Cleaning ability and cleaning quality are not enough; Can not carry out sharp work point shifts and moves.See CN87201638U and CN2063955U.
The purpose of this utility model is exactly will provide a kind of to be applicable to electrified circuit and mountain route, to have strong cleaning ability and can to realize that sharp work point shifts and the efficient small-sized screen scarifier of resettlement.
The utility model adopts that the side slope symmetry is dug in advance, with interior compact Layout, each equipment be the integral rigidity assembly from pillow end crossbeam dismounting back to equipment at electrified circuit and mountain route line circle, is suitable for special-purpose resettlement device and it is carried out setting shifts and transport.Swinging pilled-in selvedge side slope digging mechanism can change the excavation width.8～15 ° of screen scarifier rearward end updips satisfy the railway roadbed requirement for height to guarantee backfill.Be provided with dregs-equalizing plate in the screen box to guarantee the cleaning effect.
Compared with prior art, the utlity model has the characteristics of compact conformation, can be used for the full section sorting operation of electrified circuit and mountain area small radius circuit, also can be applicable to general circuit homework.The utility model has considered especially that also the screen scarifier setting shifts and transportation, and operation time is descended greatly.In addition, the utility model also excavates problem such as width adjustment and has carried out improving design with regard to the backfill that brings after the compact design, side slope, make the more monolateral excavation cleaning of the utility model mode have bigger cleaning area, thereby guaranteed the raising of cleaning ability and quality.
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is the utility model sieve cleaning mechanism phantom drawings.
Accompanying drawing 3 is the utility model side slope digging mechanism front views.
Accompanying drawing 4 is the utility model backfilling mechanism front views.
Below in conjunction with accompanying drawing an embodiment of the present utility model is done detailed description.
With reference to accompanying drawing 1, sorting operation partly is the center symmetry, and forms by digging formula side slope digging mechanism (3), pillow end master digging mechanism (5), pillow end crossbeam (7), walking mechanism (6), sieve cleaning mechanism (4), backfilling mechanism (2) and blowdown mechanism (1) in advance.Left and right sides homework department after the both sides dismounting of pillow end crossbeam (7) is divided into stiff member, can carry out setting by Handling device to it respectively and shift or transport.Compact the utility model appearance and size of disposing is less than electrified circuit line circle, this cleaning function operation on electrified circuit and mountain route.
With reference to accompanying drawing 2, sieve cleaning mechanism of the present utility model is after shrinking to the center, and the inclination angle of backfill conveyor chain can increase excessive, not smooth for preventing backfill, special with 8～15 ° of screen cloth rear end part updips, have higher entrance to guarantee the backfill chain, with angle to reduce backfill.The bottom of screen box (9) is provided with thrust wheel (8), to improve structure stress.Be provided with dregs-equalizing plate (12) in the screen box, there is helical spring (11) at the dregs-equalizing plate two ends, dregs-equalizing plate tangles in fixed vertical hinge (10) respectively and adjusts the interstitial hole of vertical hinge (13), and adjusting lever (14) is realized grade adjustment that has of dregs-equalizing plate (12) by being fixed on alignment pin (15) on the screen box.
With reference to accompanying drawing 3, side slope digging mechanism of the present utility model is by realizing the revolution of side slope digging mechanism around vertical axis by excavating width adjustment oil cylinder (16), to adapt to different requirements of excavating width.Drive motors (17) postposition, and by the excavation of reducer (18) realization pilled-in selvedge, to reduce motor-driven power.
With reference to accompanying drawing 4, the drive motors of the utility model backfilling mechanism (20) places in the conveyor chain to reduce mechanism's appearance and size.
