China DTVI-2 Track Fastening Systems for Subway Supplier
Type DTVI-2 Track Fastening Systems are composed of iron base plates, tension clamps, rubber rail plates I, rubber rail plates II, gauge insulators, screw spikes, heavy spring washers, and nylon sleeves. In addition, in order to adjust the height of the rail, the height adjustment pad is necessary.
Introduction of DTVI-2 Track Fastening Systems for Rapid Transit
- Tension clamps
There are two types of tension clamps, namely the joint D1 rail clips used in the joint part and the intermediate D1 rail clips used in the middle part, both of which have a diameter of 18mm.
- Rubber rail pad I
The rubber rail pad I is an under-rail backing plate placed under the steel rail, with a thickness of 12mm.
- Rubber rail pad II
The rubber rail pad II is a backing plate placed under the iron backing plate, with a thickness of 12mm.
- Gauge Insulators
There are two types of gauge insulators, namely the joint gauge pads used in the joint part and the intermediate gauge pads used in the middle part. At the same time, the gauge pads required to adjust the gauge are divided into No. 6, No. 8, No. 10, and No. 12.
- Nylon dowels
The nylon dowels are embedded in the sleeper in advance, and the embedding accuracy should meet the requirements. After the dowel is buried, it should be covered with a plastic (or other material) cover to prevent rainwater and mud from entering.
- Height adjustment pad
The height-adjusting pad is divided into four specifications: 2mm, 3mm, 5mm, and 10mm according to the thickness.
