Embodiment Construction

[0014] As shown in the accompanying drawings, the construction machine (1) for excavating track ballast of the present invention is made up of a power car (2), a work vehicle (3), and a ballast throwing car (4). The operating vehicle (3) includes a frame (8) that utilizes a rail mechanism to walk on the track. The frame (8) has the characteristics of low middle protrusions at both ends, and the middle protrusions allow space to place relevant operating mechanisms. The guide groove ( 17) Placed obliquely on the frame, the upper end is supported on the left upper part of the frame (8), and the lower end is located in the middle of the frame (8). During operation, it can be moved along the working direction with the frame (8). Full-section circular ballast excavation The rake chain (18) is assembled in the guide groove (17), and an adjustment device that can change the height of the excavation rake chain (18) and the position perpendicular to the direction of the track is installe...

Abstract

The invention relates to a construction machine for replacing ballasts of a rail; a power vehicle, an operational vehicle and a ballast throwing vehicle are coupled and sequentially arranged, wherein the power vehicle is provided with a ballast hopper B, a material receiving end of a new ballast transportation device is arranged at an outlet of the ballast hopper B, a material discharging opening of the new ballast transportation device extends above a ballast hopper A of the operational vehicle, and a material discharging end of the ballast hopper A is a new ballast hopper; the ballast throwing vehicle is provided with a ballast throwing transportation device; the operational vehicle comprises a convex frame and a rail-lifting device connected with the machine frame; a side slope excavating mechanism is hung below a bulge in the middle of the rack; a first transportation system is arranged between the side slope excavating mechanism and the ballast throwing transportation device; one end of an excavating harrow chain extends below the bulge of the rack, the other end of the excavating harrow chain which is the material discharging end is arranged above one end of the rack, and a second transportation system is arranged between a material discharging end of a guiding slot and the ballast throwing transportation device. Compared with the prior art, the construction machine can carry out both the entire fracture surface excavation and side slope excavation and can throw out old ballasts and supplement new ballasts, thereby increasing the working efficiency.

Description

technical field [0001] The invention relates to a railway track maintenance machine, in particular to a construction machine for replacing track ballast. Background technique [0002] The sieve cleaning machine that No. 02118337 patent introduces is used for sieving the gravel ballast bed is made up of frame and two excavating chains that are arranged in front and back along the longitudinal direction of the machine and are arranged between the track mechanism and are used to collect ballast. A set of first conveying device is arranged between the first excavating chain at the front and the first screening device at the front. The ballast collected by the second excavation chain is sent to the second screening device at the rear end of the machine through the second conveying device for cleaning. [0003] For existing ballast cleaning and screening machines, generally there is only one set of full-face circulating excavation mechanism, and the efficiency of ballast extracti...
