Description
Technical Field
The application relates to the technical field of train detection, in particular to a steel beam for monorail train contact and non-contact on-line detection.
Background
The single-rail system can be better suitable for complex terrain and landform environments. The width of the pier of the viaduct of the straddle type monorail is less than 2 meters on average, compared with other viaduct traffic, the occupied area of the pier is saved by about half, the pier can be used as a stand column in the center of an urban road or in green belts at two sides of the urban road, the occupied area is small, the shielding is less, and the line selection is flexible. Rubber-tyred rail systems are a form of rail transportation that uses tire technology for road traffic. The wheels of the train are not traditional steel wheels any more, but rubber wheels are used instead, the running track of the train is also different from the traditional steel wheel track, and the train has the advantages of low running noise, higher acceleration and deceleration rate and stronger ground biting capability. However, because of the friction of tires, while tires are cheaper than steel tires, the rate of replacement is much higher than that of steel tires, phase changes make the maintenance of rubber tire systems expensive, and the low prevalence of rubber tire track technology also results in high installation and maintenance costs.
The bogie is one of the most important parts in the structure of the railway vehicle, and the main functions of the bogie are as follows: 1) the bogie adopted on the vehicle is used for increasing the load, the length and the volume of the vehicle and improving the running speed of a train so as to meet the requirement of railway transportation development; 2) the vehicle body can be reliably positioned on the bogie under the normal operation condition, and the rolling of the wheels along the steel rail is converted into the translation of the vehicle body along the line operation through the bearing device; 3) the support vehicle body bears and transmits various loads and forces from the vehicle body to the wheels or from the wheel rails to the vehicle body, and the axle weight is uniformly distributed. 4) The safe operation of the vehicle is ensured, and the vehicle can flexibly operate along a straight line and smoothly pass through a curve. 5) The bogie has a structure which is convenient for the installation of the spring damping device, so that the spring damping device has good damping characteristic, the interaction between a vehicle and a line is alleviated, the vibration and the impact are reduced, the dynamic stress is reduced, and the running stability and the safety of the vehicle are improved. 6) The adhesion between the wheel rails is fully utilized to transmit traction force and braking force, and the braking force generated by the brake cylinder is amplified, so that the vehicle has a good braking effect, and the vehicle can be stopped within a specified distance. 7) The bogie is an independent part of the vehicle, and the number of joints between the bogie and the vehicle body is reduced as much as possible.
However, since a monorail train normally has 8 bogies with 4 guide wheels, 2 stabilizing wheels, 2 running wheels and 2 sets of collector shoes on each bogie, there are 64 tires and 16 sets of collector shoes in total for a single train. Therefore, manual detection of the state of the tire and collector shoe results in a large amount of work and is inefficient. The traditional manual detection efficiency is low, the manual interference is large, the regular, systematic and efficient detection of the train equipment cannot be carried out, meanwhile, the health condition of the train equipment cannot be reflected timely, and the running state is evaluated to be improved.
