Description :

　　ZDK622-4-12Mining single switch turnouts and turntables are produced in the south of Chahe River

　　ZDK622-4-12The price of the ZDK series single turnout produced in Henan province for mining, including a 30kg rotary switch and a 22kg single turnout core, as well as a 30kg single turnout rotary switch

　　ZDK622-4-12Single switch is a line connection device that allows locomotives and vehicles to switch from one track to another, usually installed in large quantities at stations and marshalling yards. With turnouts, the passing capacity of the line can be fully utilized. Even for single track railways, laying turnouts and constructing a section of siding longer than the length of the train can allow trains to run in opposite directions.

　　Each set of turnouts consists of a switch, switch center, two guard rails, and switch sleepers. The long handle uses the principle of lever to move the two movable tracks, allowing the vehicle wheel flange to enter the predetermined route in the opening direction. Due to the characteristics of large quantity, complex structure, short service life, limited train speed, low driving safety, and large maintenance investment, turnouts are known as the three weak links of the track, along with curves and joints. There are three basic forms of it: connection of lines, crossing, and combination of connection and crossing.

　　ZDK622-4-12Each single switch has its own code, such as 3 switches, 4 switches, 7 switches, 9 switches, and so on. This code is not arranged randomly, it actually represents the residual tangent value of the frog angle (α), which is the ratio of the two right angled sides FE and AE of the right angled triangle at the frog center, i.e. N=cot α=FE/AE, where N is the turnout number. It is obvious that the smaller the frog angle α, the larger the N value, and the larger the radius of the lead curve. The smoother the train passes through the switch on the siding, and the higher the allowable speed for passing through the switch. So using large turnouts is advantageous for train operation. However, things always have their two sides. The larger the number of turnouts and the longer the turnouts, the higher the cost and the larger the land occupation. Therefore, the number of turnouts to be used should be tailored to local conditions and vary depending on the line, and cannot be generalized. The switch numbers used in general mines are relatively small. For example, switch number 2 is a non-standard model, while switch numbers 3 and 4 are widely used.

　　The model representation of ZDK622-4-12 single turnout:

　　Z: Narrow gauge

　　D: Single opening

　　K: Turnouts

　　6: 600 gauge

　　22:22kg steel rail

　　4: Switch number

　　12: Bending radius 1200mm

　　The model of the ZDK622-4-12 single switch must be provided by the customer when purchasing, and the customer should choose the required switch model according to local conditions. Once processed and produced, it cannot be replaced. The gauge of the turnout, the weight of the steel rail, the turnout number, and the bending radius are all indispensable.

　　Yucheng friendly reminder: When purchasing a single switch, the product model must be provided by you. You need to choose the required switch model according to local conditions, including the track gauge, rail weight, switch number, and bending radius, all of which are indispensable.

　　Another point is that because turnouts are different from other products, once processed and produced, they cannot be replaced, making it difficult for customized products to be resold after return. So before purchasing, be cautious and careful again, determine the specific situation of the switch you need, and we will check the quality. You can rest assured.
