Description
Technical field
The invention belongs to the railroad track parts, be specifically related to a kind of turnout movable point frog base plate.
Background technology
The heart rail of switch movable point rail frog can slide in the wing rail framework, thereby kept vehicle continuous by the path of direction, eliminated the idle space of fixed railway frog, safety and comfortableness that vehicle passes through have been improved, China railways speed-raising and high-speed switch all adopt the structure of movable-point crossing, backing plate in this structure is made up of sliding bed platen and bed piece two parts usually, adopts the mode of welding will slide a platen and bed piece connection.Apart recently, the space is the narrowest and small for throat of frog place two wing rails, because the restriction of space structures and the functional requirement of track switch itself make that some slides bed platen both for the slip of heart rail provided supporting behind the throat of frog, has the function of withholding wing rail rail limb again.
Adopt the structure of the movable-point crossing of existing backing plate, the order of laying to wing rail and backing plate in the process of railway frog assembling has certain restriction, if change the operation of backing plate, need be with railway frog dismounting again a time, the precision and the efficient that influence the track switch assembling and lay, increase the difficulty of track switch debugging, make troubles to railway frog assembling and maintenance work.
In addition owing to adopt welding procedure to connect between sliding bed platen and the bed piece, all there is weld seam two sides along sliding bed platen length direction, welding process is difficult to avoid to cause backing plate to produce permanent set, therefore must carry out that reversible deformation is handled or the measure taking to eliminate residual stress is carried out leveling to backing plate to backing plate, increase manufacturing procedure and cost of production.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of turnout movable point frog base plate is provided.The support platform that this backing plate both provided movable point frogs to slide can provide the buckle press to wing rail rail limb again consistently, can also improve the precision of the assembling and the laying of movable-point crossing, improves part replacement efficient, is convenient to mounting turnout and maintenance.
Realize that the technical scheme that the object of the invention adopts is: turnout movable point frog base plate comprises bed piece, sliding bed platen and elastic pressure bar; Described bed piece is provided with the rail brace positioning boss, and the both sides of bed piece are respectively equipped with a pair of positioning boss and a pair of load platform; The two ends of sliding bed platen are respectively equipped with the connecting portion of downward band through hole, and sliding bed platen is positioned at above the bed piece, and connecting portion is placed between the positioning boss of bed piece; Described elastic pressure bar comprises the body of rod, through hole on the connecting portion that is provided with on the body of rod with sliding bed platen is or/and the eccentric boss that the load platform on the bed piece matches, and elastic pressure bar passes the through hole on the connecting portion and is supported on will slide a platen under the load platform of bed piece and bed piece links together.
The described connecting portion of sliding on the platen is a T-connecting piece, and this T-connecting piece is located in the T shape opening of sliding on the bed platen and becomes one by welding and slide a bed platen.
The body of rod of described elastic pressure bar be provided with the eccentric boss in three places respectively with sliding bed platen connecting portion on through hole and the load platform on the bed piece match.
In backing plate of the present invention, reliable for guaranteeing that bed piece and sliding bed platen connect, and slide the stability of bed platen to wing rail rail limb buckle press, elastic pressure bar can adopt spring steel to process, and has enough bending resistances and shear strength.Sliding bed platen is provided by elastic pressure bar the buckle press of wing rail rail limb, and the pressure design that elastic pressure bar flexural deformation is produced becomes and the suitable level of railway frog fastener pressure, and then sliding bed platen can be born the withhold function suitable with fastener.Elastic pressure bar is that spring steel material processes, and the body of rod is provided with the eccentric boss in three places, during installation elastic pressure bar is passed sliding through hole on the T-connecting piece of platen both sides, and the rotation elastic pressure bar can obtain because the pressure that eccentric boss produces.
The present invention is under the prerequisite of permanent backing original function, change the bind mode of sliding bed platen and bed piece, make wing rail be placed in relevant position on the bed piece, the side of sliding bed platen is along being buckled on the wing rail rail limb, the elastic force that produces down by the elastic pressure bar case of bending will be slided a platen and withhold with bed piece and be in the same place, be assembled into an integral body, fundamentally overcome the deficiency of backing plate in the technical background, make and change to some extent with former backing plate on the backing structure, and can be equivalent to fastener for wing rail rail limb provides, more constant buckle press, movable-point crossing assembling difficulty be can reduce, movable-point crossing dismounting and part replacement efficient significantly improved.
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
