Abstract
The utility model relates to a railway maintaining machine, particularly a digging device of a railway ballast cleaning-sieving machine, which comprises a lifting mechanism, a digging mechanism, a blade disc rotating mechanism and a rotary mechanism, wherein the digging mechanism is positioned on the lower part of the lifting mechanism and is rotationally connected with the lifting mechanism; the blade disc rotating mechanism is connected with the digging mechanism, so that the digging mechanism swings round a shaft on the lower part of the lifting mechanism so as to control the included angle between the digging mechanism and a railway ballast bed. In cleaning and sieving operation, the bottom cutting disc of the digging device provided by the utility model can slowly cut into the ballast bed from the sides of the ballast bed, so the utility model has the advantages of no need of previously digging grooves, first-phase preparation or manpower accessory operation, simple operation and high production efficiency.
Description
Affiliated technical field
The utility model relates to a kind of railway maintenance machinery, especially a kind of excavating gear of railroad ballast screen scarifier.
Background technology
Railway track need carry out maintenance, maintenance to it in the operation process, so that it is in the duty of normal reliable.For example, for railway ballast, when its dustiness surpasses to a certain degree, should carry out cleaning, ballast screening machine is to be used for the machinery of ballast aggregate in the ballast cleaning.It digs out dirty ballast aggregate from the pillow end, after sieving, will clean ballast aggregate and be backfilled to railway roadbed.The excavating gear of known full section screen scarifier is the loop system that is formed a sealing by the digger chain in lifting guide groove, horizontal guide groove, decline guide groove and the guide groove at present.When carrying out sorting operation, need in railway roadbed, to dig in advance a groove, digger chain is disconnected in horizontal guide groove and the junction that promotes guide groove, decline guide groove, horizontal guide groove is put in the groove, promote guide groove and decline guide groove and drop to the relevant position by the screen scarifier both sides, manually with horizontal guide groove with promote guide groove, the decline guide groove is connected, connects digger chain and by after the tensioning hydro-cylinder adjustment chain degree of tightness, digger chain just can carry out digging operation.Obviously, this excavating gear needs a large amount of preliminary preparations before carrying out sorting operation, and needs less important work.In addition, when railway switch is carried out sorting operation,, therefore need constantly to adjust the length of horizontal guide groove, change horizontal guide groove, thereby need more activity duration and artificial less important work because the width of railway ballast section changes.
Summary of the invention
In order to overcome the numerous and diverse defective of existing screen scarifier preliminary preparation, the utility model provides does not need preliminary preparation, the artificial extraordinary railway screen scarifier excavating gear of less important work.Simultaneously, also provide a kind of screen scarifier excavating gear that when carrying out the railway switch sorting operation, need not change excavating gear.
The technical scheme that the utility model adopted is: a kind of railway screen scarifier excavating gear comprises elevating mechanism, digging mechanism, cutter rotary mechanism and rotating mechanism.Elevating mechanism is connected with the screen scarifier car body by rotating beam, digging mechanism is positioned at the bottom of elevating mechanism, the bottom of one end and elevating mechanism is rotationally connected, elevating mechanism and digging mechanism form a L shaped device, cutter rotary mechanism is connected with digging mechanism, can drive the axle of digging mechanism and rotate around the elevating mechanism bottom, thus the angle of control digging mechanism and railway ballast.
Also comprise a rotating mechanism, this rotating mechanism and screen scarifier car body are pivotally connected, one end of rotating mechanism connects elevating mechanism, and rotating mechanism can be around the axle rotation that is connected with screen scarifier, thereby makes digging mechanism and elevating mechanism turn to opposite side from a side of screen scarifier car body.
Described elevating mechanism comprises column, hoist cylinder, and the bottom and the digging mechanism of column are rotationally connected, and an end of hoist cylinder is connected with column, and the other end is connected with digging mechanism.
Described rotating mechanism comprises the single-revolution beam, and rotating beam one end is connected with elevating mechanism, and an end and screen scarifier car body are pivotally connected, and respectively there is an oil cylinder rotating beam both sides, and oil cylinder one end is connected with rotating beam, and the other end is connected with the screen scarifier car body.
When carrying out sorting operation, the undercutting dish of excavating gear provided by the utility model can slowly be cut railway roadbed from the side of railway roadbed, therefore, needn't excavate groove in advance, does not need preliminary preparation, does not need artificial less important work.And can change the width of the railway roadbed section that is excavated, so when carrying out track switch railway roadbed sorting operation, do not need to change excavating gear by the angle of adjusting between undercutting dish and the railway track.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the structural representation of screen scarifier described in the utility model.
Fig. 2 is the structural representation of excavating gear described in the utility model.
Fig. 3 is the work schematic diagram of excavating gear described in the utility model when carrying out the railway switch sorting operation.
The specific embodiment
As shown in Figure 1, excavating gear 1 integral body described in the utility model is L-shaped, and it links to each other with screen scarifier car body 2.
As shown in Figure 2, excavating gear described in the utility model comprises a cutter plate 3, and an end of this cutter plate 3 and the bottom of column 4 are rotationally connected, and also comprise a cutter rotary mechanism 5, cutter rotary mechanism 5 is connected with cutter plate 3, rotates thereby drive the axle of cutter plate 3 around column 4 bottoms.Also comprise a hoist cylinder 6, these hoist cylinder 6 one ends are connected with column 4, and an end is connected with cutter plate 3.Also comprise single-revolution beam 7, rotating beam 7 one ends and screen scarifier car body 2 are pivotally connected, and an end is connected with column 4.
When carrying out sorting operation, cutter plate 3 is moved laterally to railway roadbed one side, driving by hoist cylinder 6, make cutter plate 3 reduce to sleeper 10 belows, cutter rotary mechanism 5 drives cutter plates 3, and railway ballast is inboard rotates around column 4 bottoms axial, thereby make cutter plate slowly from the oblique incision railway roadbed of this end, constantly ballast aggregate is dug out.
As shown in Figure 3, respectively there is an oil cylinder 8,9 described rotating beam 7 both sides, and oil cylinder 8,9 one ends are connected with rotating beam 7, and the other end is connected with screen scarifier car body 2.By the effect of two oil cylinders 8,9, make rotating beam 7 to rotate, thereby make this excavating gear move by side to opposite side, thereby can excavate from the both sides of railway ballast easily from one of screen scarifier car body around the axle that is connected with the screen scarifier car body.
As shown in Figure 3, when carrying out the track switch sorting operation, cutter rotary mechanism 5 drives the axle of cutter plate 3 around column 4 bottoms and rotates, thereby adjust the angle of cutter plate 3 and railway ballast, just can adapt to the variation of excavating width, when the bearing of trend of cutter plate 3 and railway ballast is vertical, reach maximum cutting width position.
