Description
Technical field
This application involves a kind of Qing Zha mechanisms being installed in railway cleaning equipment.
Background technology
Railway roadbed is railway ballast (the stone tiny fragments of stone, coal, etc.) bed course being laid on road bed, and main function is support sleeper, keeps sleeper position
It sets, prevents the vertical or horizontal movement of sleeper, the pressure on sleeper top is uniformly transmitted to roadbed, and exclude ground rainwater, makes rail
Road has enough elasticity, mitigates percussion of the rolling stock to rail.Because wind, Shui Chong bring the soil or road of railway roadbed into
The tiny fragments of stone, coal, etc. breaks pulverized powder and fills up railway roadbed gap often so that and railway roadbed forms impermeable stratum, and impeded drainage eventually leads to plate knot of ballast bed,
Flexibility decrease, damping effect is deteriorated, to influence traffic safety.Therefore, railway worker need to regularly replace the railway ballast below track.
The railway structure in China is complicated, and sorting operation environment is various, and the requirement to cleaning work is not quite similar.In order to meet
The job requirements of different circuits expedite the emergence of out ballast shoulder cleaning machine, railroad switch ballast cleaning machine, tunneling boring ballast screen scarifier, lateral incision formula screen scarifier
In, large-scale cleaning mechine.It is most important for above-mentioned cleaning mechine to excavate Qing Zha mechanisms.Wherein lateral incision formula screen scarifier
Qing Zha mechanisms are that the railway ballast excavation at railway roadbed pillow bottom is carried out using knife plate excavating gear.
Cleaning mechine in currently available technology, clear tiny fragments of stone, coal, etc. digging mechanism shape are fixed, for the construction road of situation complexity
Section bad adaptability, is particularly unsuitable for that short distance, construction space are narrow, and the section that cleaning requires when railway department is limited.Therefore,
It provides one kind not restricted by line construction, the clear tiny fragments of stone, coal, etc. machine of railway of the clear tiny fragments of stone, coal, etc. operation of railway line, especially switch area can be continuously finished
Structure just becomes urgent technical problems to be solved in this field.
