Description
Technical field
The invention belongs to high speed railway track Structural defect remedial technology field, in particular to a kind of plate-type ballastless track knot
The replacing system and method for structure hurt track plates.
Background technology
In recent years, high-speed railway is developed rapidly in China.250km/h circuit is reached for overall trip speed, is adopted
Use ballastless track structure.It is used as the main force in ballastless track structure, platy ballastless track structure（The types of CRTS I, the types of CRTS II,
The types of CRTS III）Large-scale application has been obtained in China Express Railway construction.Platy ballastless track structure it is main by rail, buckle
Part, track plates, mortar（Self-leveling concrete）Packed layer, concrete bed composition.As a kind of reinforced concrete structure, in ring
In the presence of border and train load, bad damage, destruction inevitably occur for track plates, and high ferro operating line is faced with " skylight
Time " carries out the demand of track plates replacing.In addition, fractional orbital plate bad damage due to quality of production difference is accelerated or due to outer
Portion, which hits, causes hurt, the current demand that track plates are changed is shifted to an earlier date significantly.
Because high ferro operating line can only carry out maintenance work in Window time, it is impossible to use large scale equipment, and track plates
Length is more than 5m, and thickness is more than 0.20m, and width is more than 2.5m, more than 5 tons of every piece of track plates weight, how in limited skylight
Change the disaster for being pendulum in face of work business personnel to bad damage track plates in time, in the case where not using large-scale equipment
Topic.Further, since track structure circuit is divided into straightway, curved section, superrelation on curve section, the track structure in different locations carries out rail
When guidance tape is changed, the requirement to technique is also different, particularly the track plates of superrelation on curve section, changes difficulty bigger.
The research that at present track plates are changed with technology both at home and abroad is still in conceptual phase.Works department is carried out in Window time
It is " cut rail change method " that track plates, which change the method used, i.e., in progress track plates replacing, first by track plates to be replaced and its
Front and rear certain length rail cutting, removal, the lifting appliance of second hand rail road car move into the removal of hurt track plates, new-track plate,
Then welding locks rail again.This method benefit is that the old plate of track plates is removed and new plate hangs in relatively simple, is existed
Greatest problem is rail must to be cut before plate is changed, removed.On the one hand this means change after plate that rail weldering must also be carried out
Connect, polish and the special work such as seam inspection, regulation input is considerably increased, in addition, everywhere joint-cutting means steel at one
Rail joint, and weld larger to rail failure, new security risk point is formed, in addition, this method work efficiency is low, manpower is put into
It is many, it is generally desirable to which three skylights could complete the replacing of one block of plate.It can be said that this is a kind of side done something against one's will
Method.
Patent " a kind of plate-type ballastless track track plates more changing device and replacing options（201310108682.3）" provide
One kind does not cut off rail and carries out plate-type ballastless track track plates more changing device and replacing options, i.e., rail is carried out after jacking, from
The method that side is removed or shift-in track plates carry out track plates replacing.This method avoid " cut rail and change method " to the wound of rail
Damage, but the deficiency existed is that frock is heavier, complex procedures, is unsuitable for constructing in Window time, meanwhile, its engineering method is only adapted to directly
The replacing of line segment track plates, it is impossible to carry out the replacing of curve freeboard section track plates." a kind of subway changes wooden handcart and comprising the subway to patent
That changes wooden handcart changes trigger group（201420251605.3）" there is also equipment enlarging, complicate the problem of, when being not suitable for skylight
Between construct.
Research one kind does not cut that rail, frock be simple, process is easy, it is adaptable to which straight line, the track plates of superrelation on curve section are changed
Complete set technology is this area urgent problem to be solved.
The content of the invention
It is an object of the invention to solve the above problems there is provided a kind of transverse direction pull out after rail carry out track plates replacing system and
Method.Main technical schemes are to carry out the replacing of track plates after rail by laterally pulling out.One side rail transverse direction stiffness is small, laterally pulls out
Power needed for rail is much smaller than the power needed for vertical head track, more controllable in force, and is difficult to cause rail damage, completely can be with
Carry out lateral pushing；After two aspect rail are unpluged, the space needed for track structure vertical lifting is accordingly discharged, for straight line
Section, superrelation on curve Duan Junke removed and changed using the method for vertical lifting to track plates, it is to avoid existing technology is from side
A series of problems, such as face changes the big frock weight brought of track plates, complex procedures, is not suitable with superrelation on curve section, also solves and cuts
A series of problems that ability vertical lifting is brought after rail；Three be required tooling device miniaturization, and operation work efficiency is fast, is adapted to
The requirement of high ferro " Window time " maintenance.
The major technique content of the invention is as follows.
