Problems solved by technology

[0008] The existing 60T self-dumping car adopts cylinder drive and big knife folding, which has a large self-heavy, small load, complex structure and manufacturing process
In particular, due to the bulky structure of the carriage and the opening and closing mechanism, and the slow opening of the side door when tipping over, the unloading stability of the vehicle is poor, and there is a risk that the carriage will be buckled and overturned during unloading
[0009] However, the above three patents only involve the concept of the large-volume rollover compartment structure, and the patents do not describe how the large-volume compartment can solve practical problems such as poor rollover stability, unloading residue and slag inclusion, nor describe the side door operating system.

Abstract

The invention relates to a railway side dumper. The railway side dumper comprises a side dumper chassis assembly, a carriage assembly arranged above the side dumper chassis assembly, a side door opening and closing mechanism for controlling opening and closing of a side door, a bogie arranged at the bottom of the side dumper chassis assembly, an air brake mounted at the bottom of the side dumper chassis assembly for service-braking wheels on the bogie, a parking braking device mounted at the bottom of the side dumper chassis assembly for parking-braking the wheels on the bogie, and a draw gear buffering device mounted on the end portion of the side dumper chassis assembly. The railway side dumper also comprises a pneumatic control hydraulic system for controlling a plurality of side door opening and closing oil cylinders of the side door opening and closing mechanism. The railway side dumper has the advantages of being stable in side door unloading performance and safe and reliable in side door control.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a railway rollover car. Background technique [0002] The railway side dumper is mainly used for transportation and side unloading of bulk or bulk materials. Because of its two functions of integrated rail transportation and unloading to the outside of the track, it has become the first choice for service vehicles for construction along the railway. [0003] The car body part of the railway self-dumping car is mainly composed of two parts: the chassis and the independent carriage. Open the side door on the opposite side to realize the function of unloading to one side of the track. At present, the self-dumping vehicle with a load of 60T is the main type of freight vehicle on my country's railways. [0004] There are mainly three types of existing railway rollover schemes: [0005] 1. The patent No. CN200820241104.1 is the Chinese patent "Large-volume and large-loa...
