Abstract
The utility model relates to a TV-shaped detachable steel rail comprising a V-shaped steel rail base and a T-shaped steel rail, wherein the vertical part of the T-shaped steel rail is placed in a V-shaped groove of the V-shaped steel rail base and closely jointed with the inner wall of the V-shaped groove, and the top of the V-shaped steel rail base is closely jointed with the transverse part of the T-shaped steel rail; the lower part of the T-shaped steel rail is provided with one groove that corresponds to a groove line arranged at the lower part of the V-shaped steel rail base, forming a slotted drum; the slotted drum is internally provided with a filling plug; and the T-shaped steel rail and the V-shaped steel rail base are mutually connected through the filling plug. The TV-shaped detachable steel rail is simple and reasonable in structure, low in manufacturing cost, good in shake-proof effect and convenient for disassembly, installation and use. When the surface of a track is abraded, only the upper layer of abraded T-shaped steel rail needs to be detached and replaced by a new T-shaped steel rail, and the V-shaped steel rail base is retained.
Description
Technical field
The utility model relates to a kind of high-speed train track system, specifically, relates to a kind of rail that is used for various bullet trains operations.
Background technology
The rail of existing bullet train operation is all continued to use the train railway in 200 years nearly, after being worn, its raceway surface must change new-track, but the rail that changes only surface is worn, the steel body of 90% rail is still excellent, the rail of surface abrasion only removed to melt down return casting, the molten cost of production height of casting not only is when changing new-track, also increased the steel consumables cost, and removed and installed loaded down with trivial details.Because the needs of in time changing when railway need be stored certain rail in advance in order to rail wear, railroad just needs to use very big space to store these rail like this, makes the memory space cost increase.
The utility model content
The problems referred to above such as must renew more after the raceway surface wearing and tearing that the purpose of this utility model is to exist at existing rail that the dismounting that rail causes is loaded down with trivial details, casting is melt into high, a steel consumables cost height and memory space is big provide a kind of simple and reasonable, easy accessibility, vibration-isolating effect is good and the casting molten and the low TV type detachable steel rail of steel consumables cost.
The technical solution of the utility model is: a kind of TV type detachable steel rail, comprise V-type rail seat base and T-steel rail, the vertical part of T-steel rail is placed on the V-type rail and sits in the V-type groove of base, and fit tightly with V-type groove inwall, and the V-type rail is sat the top of base and the lateral part of T-steel rail fits tightly; The bottom of described T-steel rail is provided with a groove, and to sit the groove of basic bottom capable corresponding with being arranged on the V-type rail for this groove, and form a groove drum, is provided with a filling bolt in the groove drum, and T-steel rail and V-type rail are sat base and interconnected by the filling bolt;
Preferably, described V-type rail is sat the groove that is provided with on base and the T-steel rail and all is set to semicircle, and forms the groove drum of a circle;
Preferably, described filling bolt is little curved shape, and for being connected in series with the catemer of forming on the steel wire by a plurality of ball balls, the two ends of steel wire are respectively arranged with a ring earclip;
Preferably, described filling bolt is for to be series at the catemer of forming on the steel wire by eight olive-shaped ball balls;
Preferably, described V-type rail is sat on the basic side ring earclip place and is provided with the through hole that can conveniently clog the bolt turnover;
Preferably, a side of described T-steel rail mid portion is provided with a step, and corresponding mid portion is provided with the plummer of this step of carrying on the side of the V-type rail seat base that fits tightly with it;
Preferably, described step and plummer all are set to the sloping platform that the inboard is low, the outside is high, and the outside is than inboard high 1mm.
The beneficial effects of the utility model are: the utility model is simple and reasonable, and cost is low, and vibration-isolating effect is good, and demolition, installation are easy to use.After the raceway surface wearing and tearing, only need shed the T-steel rail that the upper strata is worn, the V-type rail is sat base and is remained, changing new T-steel rail gets final product, do not need whole rail removed to melt down again to return casting, not only save a large amount of engineering costs, also saved railroad and purchased the steel consumables cost and saved the molten cost of production of casting of iron company, also saved corresponding memory space simultaneously.During use, by the filling bolt T-steel rail and V-type rail seat base are carried out connection, when the raceway surface wearing and tearing needed dismounting, hooking the ring earclip by hook can disassemble clogging bolt easily.Because the filling bolt adopts the form of series connection ball ball on the steel wire, steel wire is little curved shape, and pliable and tough flexible, makes the filling bolt that the permanent position can not take place to break away from automatically, has stoped the phenomenon that gets loose that is produced because of vibration effectively.

The specific embodiment
The specific embodiment of the present utility model: shown in Fig. 1 to 7, a kind of TV type detachable steel rail, comprise V-type rail seat base 1 and T-steel rail 2, the vertical part of T-steel rail 2 is placed on the V-type rail and sits in the V-type groove 3 of base 1, and fit tightly with V-type groove 3 inwalls, and the V-type rail is sat the top of base 1 and the lateral part of T-steel rail 2 fits tightly; The bottom of T-steel rail 2 is provided with a semi-circular recesses 4, to sit semi-circular recesses 5 row of basic 1 bottom corresponding with being arranged on the V-type rail for this semi-circular recesses 4, and form a circular groove drum 6, and being provided with a filling bolt in the groove drum 6, T-steel rail 2 and V-type rail are sat base 1 and are interconnected by the filling bolt.The filling bolt is little curved shape, for being connected in series with the catemer of forming on the steel wire 8 by eight olive-shaped ball balls 7, the two ends of steel wire are respectively arranged with a ring earclip 9, the shaped steel rail is sat on the basic side ring earclip place and is provided with the through hole 12 that can conveniently clog the bolt turnover, in case of necessity, can increase half hole with the turnover of convenient filling bolt.One side of T-steel rail 2 mid portions is provided with a step 10; corresponding mid portion is provided with the plummer 11 of this step of carrying on the side of the V-type rail seat base 1 that fits tightly with it; step 10 and plummer 11 all are set to the sloping platform that the inboard is low, the outside is high; and the outside is than inboard high 1mm; guarantee that the V-type rail sits base 1 and contact closely with T-steel rail 2; help protecting the V-type rail to sit the use of base 1, increased the application life that the V-type rail is sat base 1.
During installation, the V-type rail is sat base 1 to be provided with one of groove and to be sidelong and to put outside, and be fixed on the default track place of train, and T-steel rail 2 is placed on the V-type rail seat basic 1, will clog circular groove drum 6 interior the getting final product that bolt is inserted T-steel rail 1 and V-type rail seat base 1 composition then.
Track place at the train turning, when the train tempo turn, train produces centrifugal force, big speed operation makes car body push centrifugal lateral direction to, and the weight of full car body is pressed on outer side track, at this moment, it is stressed that the V-type track is sat basic A, B, C face, resisted centrifugal maximum weight pressure effectively, the destruction that has stoped centrifugal force to cause, and D, E, F face answer structure to guarantee firm effect effectively in advance.
