Embodiment Construction

[0012] The line construction machine 1 shown schematically has a frame 3 mounted on a track 2 . Frame can walk along the working direction shown by arrow 7 on a track 6 that is made up of rail 4 and sleeper 5.

[0013] In an upwardly curved section 8 where the frame 3 is located between the track mechanisms 2, there are: the digging chain 10 that utilizes the adjustable height of the driving device 9, the lifting device 12 that utilizes the adjustable height of the driving device 11 and a set of digging Ballast unit 13. The unit is equipped with a dredging mechanism 15 that utilizes a driving device 14 to adjust the height and the vertical position of the machine. The excavating chain 10 with the chain drive 16 at its upper end and the excavating unit 13 is located below the upwardly bent section 8 of the frame 3 . When the highest point 17 of the excavating chain 10 to the vertical line is in the operating position, the reference plane 19 formed by the wheels of the distanc...

Abstract

The present invention provides a line construction machine (1) for excavating track bed material, including a frame (3) with an upward bending section (8) supported on a rail-mounted mechanism (2). An excavation chain (10), a digging set (13) provided with a digging mechanism (15) by utilizing a drive device (14) to regulate the height and the horizontal position which is vertical with the longitudinal direction of the machine are arranged below the upward bending section (8) on the frame. And a track jack (12) is arranged between the excavation chain (10) and the digging set (13). In addition, a discharging chute (29) with a ballast releasing entrance (28) is directly arranged behind a receiving end (22) of a conveying device (21) below the excavation chain (10).

Description

technical field [0001] The invention relates to a line construction machine for excavating track bed materials. Background technique [0002] A kind of line construction machinery that No. EP0663472A1 patent introduces for clearing and screening track ballast is known. This mechanically encircled excavation chain of the frame is equipped with a screening device. The stored ballast can be supplemented from the ballast storage vehicle to the cleaned ballast by using the ballast storage device at the rear end to form a new ballast bed. In front of the excavation chain there is a ballast suction pipe connected to the vacuum device, which can adjust the height and lateral position. With this ballast suction pipe ballast can be suctioned before the excavation chain is used to form a so-called box hole. This opening is necessary when passing the transverse segments of the excavation chain through the ballast bed from under the track. [0003] No. US 5257580 patent...
