Description

Load-increased container flat car body adapted to the operation of Thailand's meter-gauge railway

technical field

The utility model relates to a container flat car body, in particular to a load-increasing container flat car body suitable for the operation of Thailand's meter-gauge railway.

Background technique

Thailand’s container railway transportation is mainly concentrated between the capital Bangkok and the deep-water wharf in the southern bay. This section of the line is mainly made of 80-100 lb (36-45kg) steel rails. The line is relatively straight, the minimum curve radius is R800m, and the maximum slope is 10‰ , the maximum running speed of the vehicle is 80Km/h. The maximum axle load of the existing container flat cars in Thailand does not exceed 16t. Due to the limitation of the axle load of railway vehicles, the maximum load of the vehicles does not exceed 48t. An existing container flat car can only transport a 30.48t container. However, most of the existing vehicles in Thailand can only load two 24t 20ft containers or one 30.48t 40ft container at a time, lack of 30.48t 20ft container transportation conditions, and the maximum rated mass of 20ft international standard containers varies from 24t to 30.48t And the current situation of increasing throughput forms a contradiction.

The height of the railway limit in Thailand is small. Due to its limitation, the height of the container bearing surface on the car body of the container flat car should be controlled at 1005mm from the rail surface. Considering the bearing capacity of the bogie, the height of the bogie center plate cannot be reduced infinitely, so the container The height of the middle beam end (drawing beam) of the flat car body needs to be controlled at 250mm. At present, the existing car body mostly adopts two 250mm high hot-rolled channel steel welded together to form a longitudinally penetrating center beam, and a quilted frame structure composed of angle steel is used behind the pillow. The torsional and torsional rigidity is not large, and the center of gravity is too high, which is not conducive to the improvement of vehicle dynamics. In addition, many welds need to be arranged on the center beam of the above-mentioned truss structure, and the manufacturing process is poor. The welds on the main stress-bearing parts cause stress concentration to deteriorate, weld fatigue cracks occur frequently, main body maintenance is frequent, and the service life is shortened.

Due to the low rigidity of the center beam, the existing car body is supplemented by adding more transverse beams. There are as many as 8 sets of transverse beams behind the pillow. The assembly process is cumbersome and the self-weight increases. Moreover, the layout of these transverse beams is relatively isolated from the layout of the container locking device, and the force of the locking load-bearing structure at the first stress point of the car body cannot be continuously transmitted to the middle beam frame through the transverse beams, resulting in the load-bearing structure of the lock. The force is concentrated and the local deformation is large. In addition, the width of the Thai railway limit is small. Due to this limitation, the difference between the body width of the container flat car and the width of the container corner fittings is small, which makes it difficult to lock the load-bearing structure and the position of the side beams, and easily cause the stiffness of the side beams to be lost. , there is a risk of a sharp increase in the local stress of the side beam.
