Abstract
The utility model discloses a semi-linear type split switch. The semi-linear type split switch comprises a stock rail and a switch rail. The switch rail comprises a linear section and a curve section. One end of the linear section and the stock rail intersect, and the other end of the linear section is connected with the curve section. The curve section is tangent with the linear section. The tangent section of the curve section and the linear section is arranged at the front end of the starting point of a slicing section of the linear section; in this way, the switch rail slicing portion of the linear section can be located on the inner side of the theoretical arc of the curve section, the abrasion, generated when a train passes through the switch in the side direction, of the switch rail slicing portion can be reduced, the service life of the switch rail can be prolonged to the maximum extent, and namely the semi-linear type split switch has the advantages of good wear resistance and long service life of the linear switch rail. Besides, through the design of a reasonable distance between the working edge of the curve section and the stock rail, the angle of shock of the switch rail can be smaller, the shock, generated when the train arrives at the switch in the direction opposite to the side direction, on the switch rail can be reduced, the traveling safety is improved, and namely the semi-linear type split switch has the advantage of good comfort of the curve type switch rail when the train arrives at the switch in the direction opposite to the side direction.
Description
Technical field
The utility model relates to railway technique for fixing field, refers to particularly a kind of half line type split switch.
Background technology
Tongue is the vitals of track switch, relies on pulling of tongue, and train is introduced to main track or side line direction.The type of point tongue can be divided into linear pattern and shaped form, and wherein shaped form tongue can be divided into again secant type, half secant type, tangent type, hemisection line style and from hemisection line style.The hemisection section top width of linear pattern tongue is large, whole tongue is that a straight line is positioned at the theoretical circular arc of lead curve inner side, therefore this tongue manufacture is simple, and abrasion resistance is good, but the tongue angle of shock of linear pattern tongue is large, and impact suffered in the time that train enters to branch off against side direction is large, easily make train rock, and because tongue is short, heel of switch rail generally adopts movable joint to connect, structural weak; Shaped form tongue radius of lead curve is large, the tongue angle of shock is little, and when train is crossed trouble, comfortableness is good, but the hemisection section top width of curved switch is little, and tongue is positioned at lead curve theoretical circular arc inner side and shielded length is short, the wearing no resistance of tongue, and application life is short.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, and a kind of half line type split switch of good, the Stability Analysis of Structures of comfortableness, long service life when having train-side and branching off to mistake is provided.
The technical solution of the utility model is: a kind of half line type split switch, it comprises stock rail and tongue, it is characterized in that: described tongue comprises straightway and curved section, described straightway one end is crossing with stock rail, the other end of straightway is connected with curved section, described curved section and straightway are tangent, and described curved section and the phase section of straightway are arranged on the slicing section starting point front end of straightway.
In such scheme:
Described straightway comprises the slicing section of tongue; Described curved section is the non-slicing section of tongue.
Described straightway also comprises non-slicing section, and described non-slicing section is arranged on the front end of slicing section, and curved section is connected with non-slicing section and is tangent.
Described curved section is the one in one section of circular curve, multistage circular curve or easement curve.
The working edge of described curved section and the position relationship of the working edge of stock rail be from, tangent or cut mutually in one.
The utility model has the advantage of:
1, the utility model due to curved section and straightway tangent, and phase section is arranged on the tongue slicing section starting point front end of straightway, can make the tongue slicing part of straightway be positioned at the theoretical circular arc of curved section inner side, abrasion to tongue slicing part can reduce train and go out to branch off along side direction time, improve to greatest extent the application life of tongue, there is the good and long service life of linear pattern tongue abrasion resistance.
2, the utility model can by the working edge of curved section reasonable in design and stock rail from value, can make the tongue angle of shock less, impact to tongue can reduce train and enter to branch off against side direction time, improves the safety of driving, has advantages of that when shaped form tongue train enters to branch off against side direction, comfortableness is good.
Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present utility model;
Fig. 2 is tongue straightway of the present utility model place generalized section;
Fig. 3 is tongue curved section of the present utility model place generalized section.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of half line type split switch as shown in FIG., it comprises stock rail 1 and tongue 2, tongue 2 comprises straightway 2.1 and curved section 2.2, straightway 2.1 one end are crossing with stock rail 1, the other end of straightway 2.1 is connected with curved section 2.2, curved section 2.2 is tangent with straightway 2.1, curved section 2.2 and the phase section of straightway 2.1 are arranged on slicing section starting point (the first slicing end when practice of construction) front end of straightway 2.1, can make like this tongue slicing part of straightway 2.1 be positioned at the theoretical circular arc of curved section 2.2 inner side, abrasion to tongue slicing part can reduce train and go out to branch off along side direction time, improve to greatest extent the application life of tongue, there is the good and long service life of linear pattern tongue abrasion resistance.
In the present embodiment:
Straightway 2.1 comprises slicing section and a bit of non-slicing section of tongue, and non-slicing section is arranged on the front end of slicing section, and tongue slicing part is set to straightway, can eliminate the problem that small size code channel switch track is widened apart from structure, also can facilitate prefabrication; The non-slicing section that curved section 2.2 is tongue forms separately, and curved section 2.2 is connected with non-slicing section and is tangent.
Curved section 2.2 is the one in one section of circular curve, multistage circular curve or easement curve.
The working edge of curved section 2.2 and the position relationship of the working edge of stock rail 1 be from, tangent or cut mutually in one, from value or mutually the concrete value of the value of cutting should determine according to parametric synthesis such as the requirement of the tongue angle of shock and total length of turnout, radius of lead curve.Therefore, the utility model can make the tongue angle of shock less from value or the value of cutting mutually by reasonable in design, the impact to tongue can reduce train and enter to branch off against side direction time, the safety that improves driving, has advantages of that when shaped form tongue train enters to branch off against side direction, comfortableness is good.
Heel of switch rail of the present utility model, except adopting movable joint, also can adopt elasticity bendable structure, and its Stability Analysis of Structures, can reduce on-the-spot maintenance workload, convenient for superlong jointless line.
