Abstract
The invention provides equipment for carrying out conductive material flame spraying on the surface of a railway steel rail. The equipment comprises a rail cart, a generator, a driving device, spraying guns, a material conveying mechanism, a fuel mechanism, a combustion-supporting material mechanism, a cooling mechanism and derusting devices. Wheels are arranged under the rail cart so that the rail cart can move on the railway steel rail. The generator is arranged on the rail cart. The driving device is arranged on the rail cart and connected with the wheels, and the rail cart is driven to move through electricity provided by the generator. A nozzle of each spraying gun is downward and opposite to the surface of the railway steel rail. The material conveying mechanism is arranged on the rail cart and connected with the generator. The fuel mechanism is arranged on the rail cart and conveys fuel to the spraying gun through a corresponding pipeline. The combustion-supporting material mechanism is arranged on the rail cart and conveys combustion-supporting material to the spraying gun through a corresponding pipeline. The cooling mechanism is connected with the spraying gun through a pipeline to cool the spraying gun. The derusting devices are arranged on the surface of the railway steel rail pre-coated with conductive material.
Description
technical field [0001] The invention relates to the field of railway track spraying, in particular to a device and a method for directly flame-spraying conductive materials on rail surfaces of rails. Background technique [0002] In the railway signal electric centralized station or the section block system, two steel rails are used as conductors to transmit the signal information of the track circuit. When the train or vehicle is in the track circuit section, a short circuit is formed between the two rails, and the operating voltage of the track relay in the track circuit decreases, so that the track relay falls, and the signal interlocking system knows that there is a fault in this section. car occupied. To ensure that the section can no longer enter the vehicle. Therefore, the track circuit is the signal equipment for the signal system to ensure safety. However, in some special sections in the station, such as the crossing line or side line at the entry end of the doub...
