Abstract

The invention discloses a railway ballast excavating device of railway track clearing equipment. The railway ballast excavating device comprises a frame, railway ballast excavating mechanisms and a railway ballast conveying device. Each excavating mechanism comprises a lifting oil cylinder, a drive motor and an excavating chain assembly, wherein the lifting oil cylinder is installed on the frame in a connection mode and is connected to the drive motor, the drive motor is connected to the excavating chain assembly in a transmission mode, the excavating chain assembly is provided with an excavating chain wheel, an annular ballast removing chain and rake teeth, the excavating chain wheel is meshed with the annular ballast removing chain, and the rake teeth are installed on the annular ballast removing chain in a connection mode. The railway ballast conveying device comprises a railway ballast sucking pipe, a railway ballast storage device, a railway ballast filter, a vacuum sucking pump and a conveying belt. The railway ballast excavating mechanisms are installed on the two sides of the frame respectively, and the lifting oil cylinders of the railway ballast excavating mechanisms are installed on the frame in the connection mode through sliding mechanisms capable of moving in the width direction of the frame. According to the device, the excavation width and the excavation depth can be adjusted. The railway ballast excavating device can work in narrow work faces such as railway tunnels.

Description

technical field

[0001] The invention relates to a railway track cleaning equipment, in particular to a ballast digging device. Background technique

[0002] The cleaning operation of railway ballast track needs to crush and excavate the hardened ballast bed. The ballast cleaning operation of open-air railway has been mechanized. The restrictions are large, resulting in great restrictions on mechanized maintenance operations in railway tunnels. At present, ballast cleaning and excavation in tunnels are all done manually, with high labor intensity and low work efficiency. Ballast treatment in railway tunnels has become a blank spot in the mechanized maintenance of railway lines in my country, which restricts the development of railway mechanization in China.

[0003] German patent document DE2223312 discloses a machine that transfers the crushed stone ballast located under the track to the side slope area through the bottom excavation device. In the area of ​​the crushed ston...
