The invention relates to a highway-railway dual-purpose milling vehicle body, and belongs to track engineering vehicles. According to the technical scheme of the highway-railway dual-purpose milling vehicle body,the highway-railway dual-purpose milling vehicle body comprises a front section vehicle body, a middle sectionvehicle body, and a rear section vehicle body; the front section vehicle bodyand the middle section vehicle body are connected in a hinging mode, and a milling device fixing bracket is arranged between the middle section vehicle body and the rear section vehicle body; a milling device is mounted on the milling device fixing bracket, and a pair of guiding steel wheels and a pair of driving rubber wheels are arranged at the bottoms of the front section vehiclebody, the middle section vehiclebodyand the rear section vehiclebody correspondingly. Thehighway-railway dual-purpose milling vehicle body has the advantages that the track milling device is placed on a highway-track dual-purpose tractor,the highway-railway dual-purpose milling vehicle body is suitable for highway transportation, and the transportation cost of the device is lowered; and withahighway-railway dual-purpose tractor as a vehicle body, the transformation cost of a track tractor can be lowered,the placement position is in the middle of the rear section of the vehicle body, running stability can begreatly improved, and machining accuracy of the milling vehicle is improved.
Description
technical field [0001] The invention relates to a road-rail dual-purpose milling and grinding car body, which belongs to rail engineering vehicles. Background technique [0002] Due to the large traffic volume and high operating density of rail transit in various cities in China, the rails are used in harsh conditions, and defects such as wavy wear and fat edges are prone to occur, which have a major impact on safety, comfort, and noise. Therefore, it is necessary to To carry out regular repairs, one is to improve its stability, comfort and transportation safety, and the other is to extend the life of the rail and improve the maintenance economy. [0003] The rail milling and grinding vehicle is a new type of rail repair equipment that is clean, efficient, high-precision, and has a broad market prospect. The rail milling and grinding vehicles that appear in the market are all special-purpose vehicles for rails, suitable for long-term track milling and grinding repairs, but f...
