Description
Technical field
The utility model is related to it is a kind of can curve folding and unfolding bidirectional trolley, safeguard vehicle more particularly, to a kind of railway engineering
Can curve folding and unfolding bidirectional trolley.
Background technology
Railway engineering maintenance vehicles are according to different curing requirements（Such as rail examination, railway roadbed soil pick-up, railway roadbed snow removing, rail
Polishing etc.）Different apparatus for work is needed, these apparatus for work are required for being arranged on an independence, are convenient to operation and move spirit
On operating trolley living.The positioning of apparatus for work and rail can be realized by operating trolley and moved along rail, so as to complete
Corresponding functional requirement.At present, most railway engineering maintenance vehicles operating trolleys is still unidirectional using front and rear each draw bar
Traction, hauling ability is poor, and can not realize the fast automatic folding and unfolding of rail curved section.
With the fast development of railway construction in China and maintenance needs, the speed of service, work to railway engineering maintenance vehicles
Also more and more higher, the haulage gear of existing operating trolley can not meet high speed, efficient and feature for the requirement of industry speed and efficiency
Strong requirement.On the other hand, needing that a kind of hauling ability is strong, can realize along rail curve quickly retracting, meet general utility functions requirement
Operating trolley.
The content of the invention
Technical problem to be solved in the utility model be to provide it is a kind of be applied to railway engineering maintenance vehicles, can curve receive
The two-way operation dolly put, the lifting of dolly and the receipts in curve segment of railway from inclining can be realized respectively by hoist cylinder, centering oil cylinder
Put.Because the scalable haulage gear of Z-type both can in the horizontal plane stretch or swung in vertical plane, thus it is scalable by Z-type
Haulage gear, it disclosure satisfy that dolly lifting and by the way that length of draw bar change will caused by dolly is offset during route curve section
Ask.The utility model has Level Multiple Degree of Freedom Structures, can not only be in railway straight line section, and can also be in curve segment of railway from inclining freedom retractable
Dolly.Simultaneously, moreover it is possible to realize the change of the length of draw bar caused by dolly lifting and rail track curved section dolly are offset.
The utility model provide it is a kind of can curve folding and unfolding bidirectional trolley, installed in mobile railway engineering maintenance vehicles
On, including car wheel, wheel shaft, carriage frame platform, hoist cylinder, centering oil cylinder, guider, two-way Z-type is scalable leads
Draw mechanism, rotary swing device.
Can curve folding and unfolding bidirectional trolley when railway straight line section works, stretched by four hoist cylinders of HYDRAULIC CONTROL SYSTEM
Dolly of sening as an envoy to declines, and down maneuver is completed when dolly is down on rail, now acts on the pressure one of hoist cylinder rod chamber
It is straight to exist, i.e., to one constant lower pressure of dolly to ensure the stability of dolly high-speed cruising.It is double during dolly decline
It will be changed to the length of the scalable haulage gear of Z-type, when two-way Z-type scalable haulage gear is when moving to horizontal level
Its length is most short.When dolly needs lifting by the retraction of four hoist cylinders of HYDRAULIC CONTROL SYSTEM, lifted in dolly
During dolly transverse direction and longitudinal direction position can be controlled so that dolly can correctly stop at latched position by guider.
Can curve folding and unfolding bidirectional trolley when curve segment of railway from inclining works, stretched by four hoist cylinders of HYDRAULIC CONTROL SYSTEM
Dolly of sening as an envoy to declines, while adjusts position of the dolly with respect to rail by the transverse shifting of centering oil cylinder control dolly, makes small
Car is down on rail.Dolly decline and during the length of the two-way scalable haulage gear of Z-type will change, when dolly exists
During curve motion due to sweep the different two-way scalable haulage gears of Z-type length also by difference.When dolly needs to carry
By the lifting truck that retracts of four hoist cylinders of HYDRAULIC CONTROL SYSTEM when rising, while pass through the horizontal stroke of centering oil cylinder control dolly
The position that dolly is oppositely oriented device is adjusted to movement.When dolly is promoted in the guide range of guider, by leading
Dolly can be enable correctly to stop at latched position to device.
More multioperation is all for those of ordinary skills known, is repeated no more.
Bidirectional trolley technical scheme provided by the utility model includes any combination of each part mentioned above, each part mentioned above
The simple change of component or combination are still protection scope of the present invention.
