Description
Technical Field
The utility model belongs to railway design and manufacturing field, concretely relates to small-size equipment suitable for stone tiny fragments of stone, coal, etc. under clearance railway main line and the switch sleeper.
Background
The track bed is a ballast (stone ballast) cushion layer laid on a roadbed and mainly used for supporting a sleeper, keeping the position of the sleeper, preventing the sleeper from moving longitudinally or transversely, uniformly transmitting the pressure on the upper part of the sleeper to the roadbed, and removing ground rainwater, so that the track has enough elasticity and the impact effect of a locomotive vehicle on the track is relieved. Soil brought into the ballast bed by wind blowing and water flushing or crushed powder of the ballast often fills gaps of the ballast bed, so that the ballast bed forms a watertight layer, water drainage is not smooth, the ballast bed is hardened, elasticity is reduced, and a damping effect is poor, thereby influencing driving safety. Therefore, railway workers need to regularly replace the ballast under the track.
At present, the railway screen cleaning work in China mainly has two modes, one mode is to utilize a large railway screen cleaner to cooperate with railway workers to carry out screen cleaning operation, and the other mode is manual screen cleaning. Although the ballast cleaning efficiency of the large-scale railway screen cleaner is high, the maneuverability is strong, the manufacturing cost is high, the popularization rate is low, and the screen cleaning work of a plurality of railway sections (especially turnout sections) in China at the present stage is mainly manual. Due to the limitation of the ballast cleaning operation space, the existing problem of manual ballast cleaning operation is that the existing equipment (shovels and hoes) is difficult to clean the ballast under the sleeper, and especially in northwest areas, the ballast cleaning operation has high labor intensity and much manpower consumption due to the severe hardening of the ballast under the railway sleeper.
The field also publishes some patents and products at home and abroad, but the railway ballast cleaning operation has certain limitations. The full-section excavating and screening machine disclosed in the Chinese patent publication No. CN201785685U can clean ballast under a main line and a turnout sleeper, but a bottom beam needs to be widened when the ballast under the turnout is cleaned, and the ballast under the composite turnout sleeper cannot be cleaned, so that the full-section excavating and screening machine is a large-scale screening machine and is expensive in manufacturing cost. Although the bottom beam does not need to be widened when the railway ballast cleaning machine disclosed in the Chinese patent publication No. CN108930204A is used for cleaning the ballast under the turnout, the ballast under the composite turnout sleeper cannot be cleaned, and the railway ballast cleaning machine is a large-scale cleaning machine, is high in manufacturing cost, needs to be maintained regularly, and is inconvenient to operate manually.
