Product Description

The main uses of insulating gauge adjustment blocks
1. Adjust the gauge
It is used to fine-tune the rail spacing to ensure that the gauge complies with the standard (such as the Chinese standard gauge of 1435mm).
2. Electrical insulation
Prevent electrical short circuits between rails or between rails and fasteners to ensure the normal transmission of track circuit signals.
3. Buffer vibration
Some insulated gauge blocks are made of elastic materials (such as nylon and glass fiber reinforced plastic), which can reduce the impact and vibration when trains pass through.
4. Fix the position of the steel rails
When used in conjunction with sleepers and fasteners, it prevents the lateral movement of rails and enhances the stability of the track.

The application scenarios of insulating gauge adjustment blocks
Insulating gauge adjustment blocks are mainly used in the following railway track systems:
Electrified railway
It is used in sections such as the automatic block section and the throat area of the station where track circuits are required to prevent signal interference.
2. Subway and light rail
As the ATP (Automatic Train Protection) system is widely adopted in subways, insulated gauge blocks can ensure the reliable operation of the track circuits.
3. Turnout section
It is used in key parts such as the pointed rail and basic rail of the turnout to ensure the stability of the gauge and prevent electrical short circuits.
4. Bridges and Tunnels
Due to the special track structure of Bridges and tunnels, insulated gauge blocks can adapt to temperature changes and maintain the stability of the gauge.
5. High-speed railways and passenger dedicated lines
Some ballastless tracks adopt insulated gauge blocks to reduce the risk of track circuit failures.

The advantages and disadvantages of insulating gauge adjustment blocks
Advantages
Ensure the gauge accuracy and improve the smoothness of train operation.
Provide reliable insulation to ensure the signal transmission of the track circuit.
Partially adjustable design for easy maintenance and adjustment.

Insulating gauge adjustment blocks are mainly used to adjust the gauge and provide electrical insulation, and are suitable for electrified railways, subways, high-speed railways, etc.
It can be classified by material into types such as nylon, FRP, and rubber composite, and by adjustment method into fixed type and adjustable type.
The future trend is the design of gauge blocks with higher strength and greater intelligence to meet the development needs of high-speed railways.
