Turnout is the locomotive of a vehicle from a Road for another, the line connecting equipment, usually at the station, the laying of large marshalling yard. 有了道岔，可以充分发挥线路的通过能力。 With turnout, the line can give full play to capacity. 即使是单线铁路，铺设道岔，修筑一段大于列车长度的叉线，就可以对开列车。 Even the single-track railway, the laying of turnout, the construction of a section of the train is greater than the length of the fork line, you can off the train. 由于道岔具有数量多、构造复杂、使用寿命短、*列车速度、行车安全性低、养护维修投入大等特点，与曲线、接头并称为轨道的三大薄弱环节。 As a large number of turnout, the structure is complicated, life short, the train speed limit, traffic safety and low maintenance, and other characteristics of the investment, and curves, joints and track known as the three weak links. 它的基本形式有三种：即线路的连接、交叉、连接与交叉的组合。 It has three basic forms: the lines of connection, cross-linking and cross-combination. 常用的线路连接有各种类型的单式道岔和复式道岔；交叉有直交叉和菱形交叉；连接与交叉的组合有交分道岔和交叉渡线等。 A common line connecting various types of single-and double-switch turnout; cross-cross and a diamond-shaped cross-straight; cross-connect with the combination of a switch and cross-reference points, such as crossing lines. 道岔是个大家族，最常见的是普通单开道岔。 Turnout is a big family, the most common is a single general turnout. 它由转辙器、连接部分、辙叉及护轨三个单元组成。 It consists of point machines, connecting part of Frog and Guarding track composed of three moles. 转辙器包括基本轨、尖轨和转辙机械。 Point machines, including the basic tracks, a sharp rail and Switch machinery. 当机车车辆要从A股道转入B股道时，操纵转辙机械使尖轨移动位置，尖轨1密贴基本轨1，尖轨2脱离基本轨2，这样就开通了B股道，关闭了A股道，机车车辆进入连接部分沿着导曲线轨过渡到辙叉和护轨单元。 When the rolling stock from the Road for A shares, B shares, mechanical manipulation Switch to track mobile location Tsim Sha Tsui, a sharp rail tracks of a basic paste, pointed out the basic two-track rail 2, and this opened the B-share Road, Road closure of the A-shares, locomotives and rolling stock into the link of the rail along the curve of the transition to lead Frog and their rail unit. 这个单元包括固定辙叉心、翼轨及护轨，作用是保护车轮安全通过两股轨线的交叉之处。 This unit includes a fixed frog heart, and wings for rail tracks, the role is to protect the safety of the wheels by two rail lines cross in it. 大家可能已经发现，车轮在通过辙叉时，从两根翼轨的最窄处到辙叉心的最尖端之间有一段空隙，这就是道岔的有害空间。 We may have discovered, through the wheel in the Frog, from the two wings to track the narrowest Frog heart of the most sophisticated and there is a gap, which is the harmful turnout space. 车轮通过此处时，有可能因走错辙叉槽而引起脱轨。 Through the wheel here, it may be headed in the wrong slot frog caused derailment. 设置护轨的目的也就在此，它要强制引导车轮的运行方向。 The objective set for it in orbit this, it should be mandatory to guide the direction of the wheel. 尽管如此，这个有害空间存在*了列车通过道岔的速度，对开行高速列车十分不利。 Nevertheless, this harmful space constraints of the train through the turnout rate, high-speed train line outside very unfavorable. 解决道岔有害空间的根本之道，当然是消灭有害空间。 Turnout harmful space to solve the fundamental way is, of course, the eradication of harmful space. 既然普通道岔做不到，就必须研制特殊道岔——活动心轨道岔。 Since the general turnout can not do, we must develop a special turnout - bifurcated track heart activity. 活动心轨最主要的特点是辙叉心轨可以板动。 Heart-track activities is the most important characteristics of heart frog plate tracks can be fixed. 当我们要开通某一方向股道时，活动心轨的辙叉心轨就与开通方向一致的翼轨密贴，与另一翼轨分开，这样一来，普通道岔的有害空间就不存在了。 When we opened the direction of a stock Road, the heart-track activities Frog heart on the track in line with the opening of the wing-track direction of paste, and another wing separate tracks, so that the general turnout of hazardous space does not exist. 实践证明，消灭了道岔有害空间，行车更加平稳，过岔速度*较小，因而特别适合运量大，需要开行高速列车的线路使用。 Practice has proved that eliminated the turnout harmful space traffic, more stable, a smaller cross the speed limit, thus particularly suitable for large capacity, the need to open the use of high-speed train lines. 既然有单开道岔，就有双开道岔、三开道岔以及多开道岔（复式交分道岔）等。 Since there are only a turnout, there is a double-switch, three more open and a turnout turnout (double cross-Turnout). 双开道岔为Y形，即与道岔相衔接的两股道向两侧分岔。 Turnout for a double Y-shaped, with turnout of the convergence of the two sides, to the bifurcation. 三开道岔如同Ψ形，同时衔接三股道，由两组转辙机械操纵两套尖轨。 Turnout as a three-Ψ, while the three convergence Road, the two groups Switch from two sets of mechanical manipulation of a sharp track. 复式交分道岔像X形，实际上相当于四组单开道岔和一副菱形交叉的组合。 Turnout double-cross like X-shaped, in fact equivalent to four single-opened turnout and a diamond-shaped cross-combination. 除此而外，还有一种交叉设备，通常使用的叫做菱形交叉。 Furthermore, there is a cross-cutting equipment, often called the use of the diamond-shaped cross. 它由两组锐角辙叉和两组钝角辙叉组成，但没有转辙器，所以股道之间不能转线。 It consists of two acute angle Frog and the composition of the two groups Dunjiao Frog, but did not point machines, so shares can not be transferred between the lines Road. 如果将复式交分道岔的X形的上面两点和下面两点分别连接起来，就是交叉渡线。 If the turnout will be double-cross the X-shaped above two points and two points respectively below link, that is, cross-crossing lines. 它不仅能开通较多的方向，而且占地不多，所以经常在车站采用。 It can not only open more in the direction, and an area of small, often in the station. 道岔各有其代号，比如9号道岔、12号道岔、18号道岔等等。 Turnout have their own code, such as on the 9th turnout, turnout on the 12th, on the 18th turnout, and so on. 这个代号可不是随便排列的，它实际上代表了辙叉角（α）的余切值，也就是辙叉心部分直角三角形两条直角边FE和AE的比值，即N=ctgα=FE/AE，N就是道岔号。 This code is not casually arranged, it actually represents the Frog Kok (α) of Cotangent value, which is part of Frog heart right triangle and two right-angle-FE AE ratio, that is, N = ctg α = FE / AE , N, is turnout. 显而易见，辙叉角α越小，N值就越大，导曲线半径也越大，列车侧线通过道岔时就越平稳，允许过岔速度也就越高。 Obviously, the smaller the angle α frog, N greater value, the greater the radius of derivative, the train lateral line through the turnout at the more stable, allowing the higher the turnout rate. 所以采用大号道岔对于列车运行是有利的。 Therefore, a large turnout for the train operation is beneficial. 不过，事物总有它的两面性，道岔号数越大，道岔越长，造价自然就高，占地也要多得多。 However, there are things which the two sides, the greater the number of turnout, turnout and the longer the high cost naturally, also covering much more. 因此，采用什么号数的道岔要因地制宜，因线而异，不可一概而论。 Therefore, what the turnout numbers to local conditions, the line to another, not to generalize.
