Small equipment for removing stone ballast below railway sleeper

Abstract

The invention discloses small equipment for removing stone ballast below a railway sleeper. The equipment comprises a vehicle body, a horizontal moving device, a lifting device, a steering device and a ballast removing device. The equipment is simple in structure, low in manufacturing cost, strong in universality, convenient to operate and easy to popularize, can remove stone ballast under a railway main line and a complex turnout sleeper, multiple devices can be used in cooperation when the ballast cleaning operation is carried out, the labor intensity of railway workers can be greatly reduced, and the manual ballast removing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of railway design and manufacture, and in particular relates to a small-scale equipment suitable for clearing ballast under railway main lines and turnout sleepers. Background technique [0002] The ballast bed is a ballast (stone ballast) cushion layer laid on the roadbed surface. Its main function is to support the sleeper, maintain the position of the sleeper, prevent the sleeper from moving longitudinally or laterally, transmit the pressure on the upper part of the sleeper to the roadbed evenly, and drain the ground rainwater. , so that the track has enough elasticity to ease the impact of rolling stock on the rail. The soil brought into the ballast bed by wind and water, or the ballast powder often fills the gaps in the ballast bed, making the ballast bed an impermeable layer and poor drainage, which eventually leads to hardening of the ballast bed, decreased elasticity, and poor shock absorption effect. Thereby...

Problems solved by technology

Chinese patent announcement number is CN201785685U disclosed a kind of full-section excavation and screen cleaning machine that can clean up the main line and ballast under the turnout sleeper, but when cleaning the ballast under the turnout, the bottom beam needs to be widened, and the ballast under the composite turnout sleeper cannot be cleaned. It is a large screen cleaning machine, which is expensive

Chinese patent announcement number is that CN108930204A discloses a kind of railway track ballast cleaning machine to clean up the ballast under the turnout though it does not need to widen the bottom beam, it can not clean the ballast under the composite turnout sleeper equally, and it is a large-scale cleaning machine, which is expensive and requires Regular maintenance, manual operation is inconvenient

At present, domestic ballast cleaning machines are used to clean ballast from under the sleepers and then screen and backfill. The disadvantages are that the models are expensive and cannot clean composite turnouts. The versatility is not strong and it is not easy for workers to operate.
