Technical Field
The utility model relates to a can solve the perpendicular wearing and tearing of frog wing rail fast, the point rail falls the intensive wing rail alloy steel frog of piece, belongs to frog and makes the field.
Background
The main diseases of the existing alloy steel combined frog used for the railway turnout are that the vertical abrasion of a wing rail is fast and the small-section scale line of a point rail falls off. The frog can get off the track in advance without reaching the service life, thereby affecting the operation safety of the train and increasing the operation cost of the railway. The wing rail of the existing alloy steel combined frog is a common on-line heat treatment steel rail, the center rail is made of alloy steel material, parts made of two different materials and having different properties support wheels in the transition area of the frog center wing rail, and in addition, impact caused by factors such as uneven top surface of the frog, different wheel abrasion and the like easily occurs, so that the two parts are different in impact and abrasion to generate damage. Therefore, the wing rail with lower performance in the main parts of the frog is lifted and strengthened, so as to solve the problems of quick abrasion of the wing rail of the frog and small section damage of the point rail.
Disclosure of Invention
The design purpose is as follows: the defects in the background art are avoided, and the reinforced wing rail alloy steel combined frog capable of solving the problems that the wing rail of the frog is fast in vertical abrasion and the point rail falls off blocks is designed.
The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design, reinforce wing rail alloy steel combination frog, mainly by alloy steel point rail, connect the point rail with the fork of end with the rail and distribute at the intensive wing rail of point rail both sides and constitute, link together through connecting pieces such as spacer iron and high strength bolt.
When the alloy steel is combined with the frog wing rail, a fully forged high manganese steel wing rail and a semi-forged high manganese steel wing rail can be adopted. The fully forged high manganese steel wing rail is made of forged high manganese steel materials for the whole wing rail; the semi-forged high manganese steel wing rail consists of two sections of a common steel rail and a high manganese steel rail which are connected together through a flash welding structure. When the semi-forged high manganese steel wing rail is adopted, one end of the wing rail connected with a circuit is a common steel rail, the other end of the wing rail is the high manganese steel rail, and a welding line is arranged in the range from the throat of the frog to the section of the point rail with the diameter of 20mm corresponding to the wing rail.
And the wing rail is reinforced by alloy steel materials. The steel rail consists of a section of common steel rail with a standard section and a section of steel rail made of alloy steel, the middle of the common steel rail is connected with the clamping plate through welding, and a welding seam is arranged in the middle of the wing rail. The wing rail alloy steel rail is made of alloy steel materials same as the core rail or alloy steel materials with performance close to that of the core rail; the alloy steel rail with wing rails has a section in the shape of a standard rail or a non-standard rail, and the alloy steel rail has a non-standard section, and two ends of the alloy steel rail are processed into the sections of the standard rail so as to be conveniently butted with the standard rail. Referring to the toe end and the heel end of the frog, the section of the wing rail near the toe end of the frog is the front end, and the section near the heel end of the frog is the rear end. The common steel rail can be welded at the front end of the wing rail (namely the common steel rail and the alloy steel rail) or at the rear end of the wing rail (namely the alloy steel rail and the common steel rail), when the common steel rail is arranged at the front end of the wing rail, the welding line is arranged in the range from the throat of the frog to the wing rail corresponding to the section of 20mm of the point rail, and when the common steel rail is arranged at the rear end of the wing rail, the welding line is arranged in the range from the wing rail to the heel corresponding to the section of 50mm of the point rail.
The welding seam is provided with two-hole or four-hole clamping plates which are connected with the steel rail through high-strength bolt pieces to reinforce the welding seam, and when the wheel passes through the steel rail, the two wing rails resist the transverse force generated by the wheel together. A gap of 0.5-1 mm is reserved between the clamping plate and the rail waist of the steel rail and is a glue joint layer, and the matching surface profile of the clamping plate and the steel rail is the same as the rail waist of the steel rail. According to different welding seam positions, the clamping plate is divided into two types: in the first type, when other connecting pieces are arranged between the two wing rails, the clamping plate between the two wing rails is of a split structure; in the second type, when no other connecting piece is arranged between the two wing rails, the clamping plates between the two wing rails are connected through the connecting plate.
In order to further improve the use performance of the wing rail reinforced rear frog, supplement the shortage of height stacking of the top surface of the raised rear rail of the wing rail, carry out planing and cutting processing on the working edge of the wing rail, enable the center of the rail head of the wing rail to be closer to the center rail, increase the height stacking of the top surface of the wing rail, enable the top surface of the wing rail to be effectively and reliably contacted with the tread of the wheel, round-off the edge of the machining edge and smoothly transit the front and the rear after planing and cutting the working edge. Because the center of the wing rail head is closer to the center rail, the contact area between the wheel and the top surface of the wing rail can be increased during driving, and the abrasion resistance of the wing rail is improved while the relationship between the wheel and the rail is improved.
The technical scheme is as follows: the utility model provides a reinforce wing rail alloy steel frog, by alloy steel heart rail, connect the fork at heart rail rear end with the rail and distribute the wing rail in the heart rail both sides and constitute, be in the same place through spacer iron and high strength bolt connection piece, the wing rail is full forging high manganese steel wing rail or half forging high manganese steel wing rail, wherein half forging high manganese steel wing rail comprises two sections, by one section standard section ordinary rail and one section forging high manganese steel material rail welding form, ordinary rail and one section forging high manganese steel material rail welding pass through flash welding, only one welding seam.
Compared with the prior art, the utility model, through reinforceing the wing rail and wheel rail relation optimization, increased wing rail top surface and wheel area of contact, improved the regional rail top surface ride comfort of point wing rail transition, improved the wing rail wearability and protected the point rail, reach and reduce wing rail wearing and tearing, prevent that the point rail from falling the piece, improving frog life's effect.
