Description
Technical field
Small-sized automatic hydraulic track lifting tamping car, belongs to railway line maintenance apparatus field.
Background technology
The effect of rolling that railway track is run due to vehicle, ballast track bed can be deformed, and track lifting operation is by iron
The low-lying place of road circuit is high, with levelling rail level, recovers the smooth-going of railway track.Track lifting is railway track maintenance, maintenance work
In key job, be the higher operation of a technical requirements.The instrument that current track lifting operation is used is divided into by manual operation
Mechanical rack rail jack and hydraulic tool for taking up tracks, and the small-sized hydraulic track jack with combustion power, no matter using what instrument,
Track lifting operation at least needs three people to work in coordination, and a Ren Kan roads, amount level, a Ren Tai roads, another people play plug.
By the mechanical rack rail jack and hydraulic tool for taking up tracks of manual operation it is a kind of hand-held tool, it is necessary to artificial transfer
Track lifting place, artificial board moves operation handle and carries out track lifting operation, and site operation personnel's labor intensity is big, with the small-sized of combustion power
Although hydraulic track jack reduces the labor intensity of operating personnel, but there is the artificial promotion transfer tasks point of needs and use loaded down with trivial details
Shortcoming, as portable track lifting instrument, need to determine to raise track according to the gesture for the personnel that see in track lifting operation process high
Degree is, it is necessary to see that the mutual close fit with track lifting personnel can be just carried out behind this work, track lifting personnel Qi Hao roads, it is necessary to be responsible for
Make the librarian use hand-rodding instrument of plug or the portable of drive makes instrument firm by ramming and carry out playing plug operation, by the track in Qi Hao roads
A temporary support is done, this mode for beating plug supporting track is only the very little that track has been supported using the lower railway ballast of pillow
Point, highly unstable, extraneous vibrations are easy to destroy the support with gravity, cause the change of track horizontal plane.
Large-scale maintenance machinery is to raise track to make integral equipment firm by ramming, high with automaticity, achievable railway track track lifting,
The synthetic job made firm by ramming, but large-scale maintenance machinery equipment price is expensive, and cost of use is high, it is difficult to which popularization is used.Although large-scale support
Road machinery can realize the automated job for raising track, making firm by ramming to railroad track, but large-scale maintenance machinery is can not to withdraw railway line
Road, moreover, the turnover station of large-scale maintenance machinery and being transferred to from parking place needs the operating location made firm by ramming to be required for
The scheduling and cooperation of railways train operation department, are interfered to normal driving.Particularly, for newly built railway circuit, it is same because
Large-scale maintenance machinery needs to travel on the railroad track, and can not be put into the case that in newly built railway, all laying is not completed makes
With only just being come into operation in the latter stage of newly built railway circuit, the track lifting tamping operation at newly built railway initial stage still needs and made
Completed with existing means, have a strong impact on the progress of engineering.In summary, made using the operating type for manually seeing, raising track, playing plug
Industry efficiency is low, and operation quality is difficult to control to, and on-site personnel labor intensity is big, is a kind of traditional forced operator
Formula.
The content of the invention
The technical problems to be solved by the invention are：Overcoming the deficiencies in the prior art, one can high-quality height there is provided one kind
Effect ground completes equipment and shifts, sees, raising track, playing plug, the disposable whole work for completing track lifting operation, can be just after the end of job
Jin Xia roads, open the small-sized automatic hydraulic track lifting tamping car that circuit recovers transport.
The technical solution adopted for the present invention to solve the technical problems is：The small-sized automatic hydraulic track lifting tamping car, including

Operation principle and the course of work：The track lifting operation process of the present invention is as follows, according to rising for railway track maintenance activity
Road job requirements, are usually to carry out track lifting operation to basic stock first, after basic stock is flat, correspondence stock is right on the basis of basic stock
Level, makes two strands of rail surfaces in the same plane.
Before track lifting operation starts, slide box assembly 503 and rise to highest stop position point, see librarian use remote control
Device starts the track lifting operation traveling of complete machine, under the control of computer control unit, and walking chassis 1 drives complete machine traveling, by seeing
Road personnel determine or that by the track lifting point of the basic stock of rail checking instrument automatic detection railway track after the point that raises track is determined, complete machine continues
Traveling, when the track lifting position alignment sensor being arranged in walking chassis 1 detects sleeper bolt, walking chassis 1 stops walking
OK, the slip box assembly 503 of left and right sides tamping agency 5 declines simultaneously, when the inspection of left and right sides lifting position alignment sensor
Measure and stop declining after the folder rail stop position locating slot on respective positioning guide column component 502, decline stop position or so herein
The clamping mechanism 3 of both sides clamps rail, and the track lifting oil cylinder 902 of basic stock side carries out track lifting operation.
Stop raising track when the personnel of seeing think and reach the track lifting height of the track lifting height of requirement or rail checking instrument detection,
The basic drive of stock Slideslip box assembly 503 is made component 504 firm by ramming and declined again, and lifting position alignment sensor detects positioning and led
Stop declining after lower end stop position locating slot on column assembly 502, the lower railway ballast of 5 pairs of pillows of tamping agency carries out folder implementation industry, reaches
Component 504 is made firm by ramming after between pressing from both sides in real time and presss from both sides real release, is slided box assembly 503 and is risen, lifting position alignment sensor is detected
Stop rising after upper end stop position locating slot on positioning guide column component 502, after basic stock track lifting terminates, see librarian use
Track forces or rail checking instrument are carried out to level track lifting operation on the basis of playing flat basic stock to correspondence stock, reach the track lifting of requirement
Stop raising track during height, the drive of slip box assembly 503 of correspondence stock side is made component 504 firm by ramming and again declined, the lifting of correspondence stock side
Position alignment sensor is detected to be stopped declining after the lower end stop position locating slot on positioning guide column component 502, correspondence stock side
Make the lower railway ballast of 504 pairs of pillows of component firm by ramming and carry out folder implementation industry, make component 504 after reaching between pressing from both sides in real time firm by ramming and press from both sides real release, slide casing
Component 503 rises, and lifting position alignment sensor stops after detecting the upper end stop position locating slot on positioning guide column component 502
Only rise, so as to complete the present invention from traveling to the track lifting for the two strands of rail of point that raised track to one, beat to fill in and make whole operations a little firm by ramming.
Operation and monitoring for ease of operating personnel to complete machine, automated job programme-control and the manual control button of remote control and joint control
System.
