Train pipe monitoring device and system and 25t axle load aluminum alloy coal hopper car system

Abstract

The invention provides a train pipe monitoring device and system and a 25t axle load aluminum alloy coal hopper car system. The 25t axle load aluminum alloy coal hopper car comprises an end wall vertical plate, a supporting plate and a bottom plate. The train pipe monitoring device comprises a strain type pressure sensor, a pressure switch and a control device, wherein the strain type pressure sensor is arranged in a mounting space defined by the end wall vertical plate, the supporting plate and the bottom plate; the strain type pressure sensor is communicated with a train pipe of the 25t axle load aluminum alloy coal hopper car; the pressure switch is arranged in the mounting space; the pressure switch is communicated with the train pipe of the 25t axle load aluminum alloy coal hopper car; the pressure switch is used for determining whether to output a trigger signal or not according to the pressure value of the train pipe; the control device is electrically connected with the strain type pressure sensor and the pressure switch; and when the control device receives the trigger signal, the control device detects the current pressure value in the train pipe through the strain type pressure sensor and outputs the current pressure value.

Description

technical field [0001] The application relates to the technical field of railway wagons, in particular to a train tube monitoring device, a system and a 25t axle load aluminum alloy coal hopper car system. Background technique [0002] Railway transportation is characterized by high efficiency and environmental protection. With the development of the world economy, railway transportation can more and more reflect its advantages. With the rapid development of the world economy, the abundant transportation of bulk goods such as minerals, grains, and chemical raw materials has created a solid and stable material foundation for the long-term and efficient operation of world rail freight. [0003] During the operation of railway freight vehicles, it is necessary to check the train pipe pressure of railway freight vehicles. At present, the detection of the train pipe pressure of the railway freight vehicle is to check whether the pressure of the train pipe is within the normal ra...
