道岔是一种使机车车辆从一股道转入另一股道的线路连接设备,通常在车站、编组站大量铺设。有了道岔,可以充分发挥线路的通过能力。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。
道岔使列车由一组轨道转到另一组轨道上去的装置。 每一组道岔由转辙器、岔心、两根护轨和岔枕组成,由长柄以杠杆原理拨动两根活动轨道,使车辆轮缘依开通方向驶入预定进路。
The train is composed of a set of tracks to the device of another set of orbits. Each group of switch by switch, frog, two guard rail and sleeper, a long handle to leverage a two movable track, the wheel rim in opening direction into the scheduled route.
single turnoutt
Single switch of the main line, line by line to the left or to the right fork, also known as the left and right turnout turnout.
equilateral turnout
Double switch is in the shape of a Y, which is connected with the two track to both sides of the bifurcation.
three-way turnout
Three turnout as "shape, and connecting the three tracks, two groups switch from two sets of mechanical manipulation of tongue.
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。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。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。
还有一种交叉设备,通常使用的叫做菱形交叉。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。
Doubleslip switches like X shape, combination in fact equivalent to four single turnout and a diamond shaped cross. The above will double cross X shaped switch points and two points respectively below link, is the crossover. It not only can open more direction, and do not cover a large area, so often used in station. There is a cross cutting equipment, often called the use of the diamond crossing. It is composed of two groups of acute frog and two groups of obtuse frog, but no switch, so the track can not transfer line.
Turnout installation device fixed screw fastening, device without the old wound crack.
Each connecting rod, the outer lock device without the old wound crack, rod without grinding card and pin hole corrosion, wear not more than 1mm, good insulation
An important part of the guard rail fixed frog of turnout, arranged on both sides of the fixed frog. Is the control wheel running direction, to prevent the harmful impact of frog space or climb the actual point of frog, the critical equipment to ensure traffic safety. In the movable point frog, a guard rail only general in the side, in order to prevent the side wear of rail.
