[0002] The car tipping machine unloading system is a large-scale automatic unloading system used in power plants, ports, metallurgy, coal, coking and other enterprises. It is a device for unloading bulk materials loaded on railway open wagons.

The utility model belongs to a wheel clamp device for preventing slipping of the heavy wagon line and the empty wagon line in the car tipping machine system.

[0003] The existing wheel clamps are basically divided into two types, one is the hydraulic wheel clamp and the other is the electric wheel clamp. The hydraulic wheel clamp is large in size and requires a lot of civil construction under the track where the wheel clamp is located. The fixing parts are embedded and the wheel clamp device is fixed on the civil foundation. The civil construction amount is large and the construction time is long. The problem of water accumulation in the foundation pit under the track is difficult to solve. The electric wheel clamp is fixed on the track and installed in the gap between the sleepers.

Under long-term overload and high-frequency working conditions, the service life of the reducer is extremely short, and the maintenance cost and workload are high. Utility Model Content
