The method includes testing equipment for the actual locked rail temperature and current rail temperature of the rail, rail stress and strain testing equipment, rail lateral pushing equipment, rail plate transportation equipment, rail plate hoisting equipment, measuring devices, and rail pulling devices. The method includes setting up a reaction force block or a reaction force device on a line at a certain distance before and after the track plate to be replaced, setting up a pushing point on the rail, loosening a certain length of fastener, and using a pushing device to push the rail to the position to be replaced. On the outside of the track plate, the old plate is removed and the new plate is placed in place by means of vertical lifting. The stress testing equipment measures the rail stress in the whole process; the measuring device is arranged outside the hanging plate operation area to control the plane position of the new plate. The method has the characteristics of light tooling, quick replacement, high work efficiency, and little damage to the rails, and is especially suitable for the "skylight time" operation of high-speed railways.
Description
Technical field
The invention belongs to high speed railway track Structural defect remedial technology fields, in particular to a kind of plate-type ballastless track knot
The replacing options of structure hurt track plates.
Background technique
In recent years, high-speed railway is developed rapidly in China.The route that 250km/h is reached for overall trip speed, is adopted
Use ballastless track structure.As the main force in ballastless track structure, platy ballastless track structure (I type of CRTS, II type of CRTS,
III type of CRTS) it builds to have obtained large-scale application in China express railway.Platy ballastless track structure mainly by rail, buckle
Part, track plates, mortar (self-leveling concrete) filled layer, concrete bed composition.As a kind of reinforced concrete structure, in ring
Under the action of border and train load, bad damage, destruction inevitably occur for track plates, and high-speed rail operating line is faced with " skylight
The demand of time " progress track plates replacement.In addition, fractional orbital plate bad damage due to quality of production difference is accelerated or due to outer
Portion, which is hit, causes hurt, and the current demand for replacing track plates shifts to an earlier date significantly.
Since high-speed rail operating line can only carry out maintenance work in Window time, large scale equipment can not be used, and track plates
Length be greater than 5m, thickness be greater than 0.20m, width be greater than 2.5m, every piece 5 tons of track plates weight or more, how in limited skylight
It is the disaster put in face of work business personnel that time is interior, carries out replacement to bad damage track plates in the case where not using large-scale equipment
Topic.Further, since track structure route is divided into straightway, curved section, the track structure of superrelation on curve section, different section carries out rail
When guidance tape is replaced, the requirement to technique is also different, especially the track plates of superrelation on curve section, and replacement difficulty is bigger.
Conceptual phase is still in the research of track plates replacement technology at present both at home and abroad.Works department is carried out in Window time
The method that track plates replacement uses is " cut rail replacement method ", i.e., when carrying out track plates replacement, first by track plates to be replaced and its
Certain length rail cutting in front and back removes, and the lifting appliance of second hand rail road vehicle removes hurt track plates, new-track plate moves into,
Then welding locks rail again.This method benefit be the old plate of track plates remove and new plate hang in it is relatively simple, it is existing
Greatest problem is must to be cut, be removed to rail before changing plate.On the one hand this means that rail weldering must also be carried out after changing plate
It connects, polish and the special work such as seam inspection, regulation investment is considerably increased, in addition, everywhere joint-cutting means steel at one
Rail connector, and welding is larger to rail failure, forms new security risk point, in addition, this method work efficiency is low, puts into manpower
It is more, it is generally desirable to which three skylights could complete the replacement of one block of plate.It can be said that this is a kind of side to do something against one's will
Method.
Patent " a kind of plate-type ballastless track track plates more changing device and replacing options (201310108682.3) " provides
One kind not cutting off rail and carries out plate-type ballastless track track plates more changing device and replacing options, i.e., after being jacked to rail, from
The method that side removes or shift-in track plates carry out track plates replacement.This method avoid " cutting rail replacement method " to the wound of rail
Damage, but existing deficiency is that tooling is heavier, complex procedures, is unsuitable for constructing in Window time, meanwhile, engineering method is only adapted to directly
The replacement of line segment track plates can not carry out the replacement 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.
It studies one kind and does not cut the track plates replacement that rail, tooling are simple, process is easy, suitable for straight line, superrelation on curve section
Complete set technology is this field urgent problem to be solved.
Summary of the invention
The purpose of the present invention is to solve the above problem, provide a kind of transverse direction pull out the system that track plates replacement is carried out after rail and
Method.Main technical schemes are that the replacement of track plates is carried out after pulling out rail by transverse direction.One side rail transverse direction stiffness is small, laterally pulls out
Power needed for power needed for rail is much smaller than vertical head track, it is more controllable in an implementation, and be not easy that rail is caused to damage, it completely can be with
Carry out lateral pushing；After two aspect rail unplug, space needed for accordingly releasing track structure vertical lifting, for straight line
Section, superrelation on curve Duan Junke are removed and are replaced using the method for vertical lifting to track plates, avoid existing technology from side
Face replacement track plates bring tooling weight is big, complex procedures, is not suitable with a series of problems, such as superrelation on curve section, also solves and cuts
It could vertical lifting bring a series of problems after rail；Third is that required tooling device minimizes, operation work efficiency is fast, is adapted to
The requirement of high-speed rail " Window time " maintenance.
Major technique summary of the invention is as follows.
A kind of method that transverse direction pulls out progress track plates replacement after rail.The method includes rail actual lock rail temperature and work as
