The present invention can be by rational deployment under limited space of each mechanism, full section excavation can be carried out and side slope excavation can be carried out again, or in the time of job requirements, only carry out side slope excavation, reach high efficiency extraction dish out ballast aggregate, carry ballast aggregate, backfill to supplement new quarrel functional purpose, and applied widely.
brief description of the drawings
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
As shown in drawings, the construction machinery of excavation orbit ballast of the present invention (1) is made up of power car (2), working vehicle (3), throwing quarrel car (4).Working vehicle (3) comprises the frame (8) of utilizing rail travelling mechanism traveling in orbit, frame (8) has the feature of the low intermediate projections in two, intermediate projections is abdicated space and is placed relevant Working mechanism, guide groove (17) is inclined in frame, upper end is supported on frame (8) upper left quarter, lower end is positioned at the middle part of frame (8), when operation, can move along operating direction with frame (8), the complete circulating ballast excavating rake chain of section (18) is assemblied in guide groove (17), between guide groove (17) and frame (8), be equipped with and can change the height of digging rake chain (18) and the adjusting device perpendicular to the position of orbital direction, the ballast aggregate that digging rake chain (18) extracts is entered and is supported in the upper left quarrel bucket of frame (8) (29) by guide groove (17), conveying device C (9) is bearing in top, frame (8) middle part as the storage end of quarrel bucket (29), conveying device D (10) is bearing in the upper right side of frame (8) as the storage end of conveying device C (9), along the front of operating direction conveying device C (9), simultaneously also as the feeding end of conveying device E (11).Side slope digging mechanism (20) is positioned at digging rake chain (18) front along operating direction, both in below, frame (8) middle part.
Side slope digging mechanism (20) hangs on below, frame (8) intermediate projections position, is positioned at the centre of whole frame, can adjust by driving mechanism front and back and the lengthwise position of side slope digging mechanism (20); It is upper and be its storage end that conveying device A (21) is supported on side slope digging mechanism (20), can regulate its Angulation changes distance that feeds intake by hydraulic cylinder; Conveying device B (22) is bearing in frame (8) as the storage end of conveying device A (21), its storage end is positioned at frame (8) below near side slope digging mechanism (20), discharge end is positioned at frame (8) top conveying device D (10) below, as another feeding end of conveying device E (11), discharging opening is positioned at conveying device D (10) discharging opening rear along operating direction, spatially staggered positions avoids ballast aggregate mutually to interfere, and the ballast aggregate of conveying merges herein; Conveying device E (11) is bearing in frame (8) upper right side, can adjust its Angulation changes ballast aggregate distance that feeds intake by hydraulic cylinder, and discharge end is positioned at throws quarrel car (4) upper left side.
Said throwing quarrel car (4) comprises the second drivers' cab (13), throws quarrel conveying device and running mechanism.Throw quarrel conveying device and comprise conveying device E (11), conveying device F (12), revolution conveying device (14).
Throwing quarrel car is that the conveying device F (12) on (4) is the storage end of conveying device E (11), and conveying device F (12) storage end is supported on vehicle frame left end, and discharge end is in the second drivers' cab (13) top; Revolution conveying device (14) is positioned at the second drivers' cab (13) top, conveying device F (12) below, the ballast aggregate of extraction is sent to storage cart (not shown) above, revolution conveying device (14) can be received to conveying device F (12) below in not operation time rotation by drive unit.Support is arranged at said the second drivers' cab (13) top, and revolution conveying device (14) is loaded on the support of drivers' cab (13).
After the ballast aggregate of extraction is dished out, need new quarrel to fill railway roadbed, the new quarrel that storage cart (not shown) by below supplements enters new quarrel conveying device (6) by the quarrel B (28) that struggles against, the discharging opening of new quarrel conveying device (6) extends to working vehicle upper left side, as the discharge end that is supported in the upper left quarrel bucket A of working vehicle (7), new quarrel is filled to railway roadbed through new quarrel bucket (30), reaches the object of changing ballast aggregate.
Rail-lifting equipment (16), working driver chamber (19), working driver chamber (23) hang on frame (8) intermediate projections part lower end, rail-lifting equipment (16) is positioned at the rear of digging rake chain (18) along operating direction, its function is to promote rail and sleeper height, be convenient to extract ballast aggregate, working driver chamber (19) is positioned at digging rake chain (18), rail-lifting equipment (16) front along operating direction, for observing the operation situation of digging rake chain (18) and rail-lifting equipment (16).Working driver chamber (23) is positioned at side slope digging mechanism (20) front along operating direction, conveying device B (22) below, for observing the operation situation of side slope digging mechanism (20), conveying device A (21), conveying device B (22).
The first drivers' cab (5), the second drivers' cab (13) are positioned at the two ends of construction machinery (1), in the time of high speed traveling or operation, use, and have from traveling ability.
