Ballast leveling mechanism for leveling ballast bed

Abstract

The invention discloses a ballast leveling mechanism for leveling a ballast bed, which belongs to railway maintenance equipment. The mechanism comprises a ballast leveling plough rack, an eccentric shaft component, a cross beam component and a connecting rod component, wherein first hammer holes are respectively formed in two plough blades, and the positions of the corresponding first hammer holes in the two plough blades are corresponding; the ballast leveling plough rack also comprises two hammer hole plates and a middle framework, second hammer holes are respectively formed in the hammer hole plates, and the positions of the second hammer holes correspond to the positions of the corresponding first hammer holes in the plough blades; the middle framework is positioned between the two plough blades and is fixedly connected with the two plough blades; the eccentric shaft component comprises an eccentric shaft; the cross beam component comprises one or more cross beams, and each cross beam comprises a left vibratory hammer, a right vibratory hammer and connecting plates, wherein the left vibratory hammer and the right vibratory hammer are respectively inserted into the corresponding second hammer holes in the hammer hole plates and the corresponding first hammer holes in the plough blades in a sliding fit manner; and the eccentric shaft is connected with the cross beam component in a driving manner through the connecting rod component. The mechanism has the characteristics of small ballast leveling resistance, and high ballast leveling efficiency.

Description

technical field [0001] The invention relates to a railway maintenance operation equipment for ballast bed leveling, in particular to a ballast leveling mechanism for overhauling trains. Background technique [0002] At present, ballast leveling operations are often carried out in the process of railway line maintenance and new line construction, the purpose of which is to shape the ballast bed and establish a good foundation for the placement of sleepers. In the mechanized road maintenance equipment, there is a set of ballast leveling mechanism specially engaged in ballast leveling operation, which can divide the excess ballast to both sides and shape the surface of the ballast bed into the required shape. The structure of the ballast leveling mechanism in the prior art is mainly composed of a ballast plow and a plow frame. The ballast plow is an arrow-shaped plow blade composed of two single plow blades intersecting obliquely and fixedly. The outer surface of the plow blade...

Problems solved by technology

However, during the operation of this kind of flat ballast mechanism, the ballast moves slowly to both sides, and it is easy to accumulate on the outside of the plow blades, or even overflow the plow blades, resulting in increased forward resistance of the equipment and low operating efficiency.
