Intelligent sleeper for detecting line quality state

Abstract

The invention provides an intelligent sleeper for detecting line quality state. According to the intelligent sleeper for detecting the line quality state, a first pressure induction device is arrangedbelow a sleeper body, a second pressure induction device is arranged in the sleeper body and is located below a steel rail, and a signal recording device is arranged on the sleeper body, so that a full-life-cycle real-time monitoring function of the sleeper is achieved. The intelligent sleeper adopts a steel rail mechanical energy electricity storage device and a solar energy electricity storagedevice which store electric energy automatically, solar energy and mechanical energy generated by small displacement of the steel rail are converted into electric energy, and the power supply problemduring sleeper monitoring is solved; sleeper state information is transmitted to remote equipment through wireless transmission, and the remote equipment processes sleeper dynamic information data andtransmits the sleeper dynamic information data to a sleeper receiving device in a dynamic two-dimensional code mode, so real-time sleeper information updating is achieved, the condition of a line canbe obtained in time, and a maintenance plan can be adjusted in time; and the function that an operation train serves as a line police is achieved, the line quality state is obtained in time through the wireless sensing technology, and safe operation of the train is facilitated.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring of the state of railway engineering lines, in particular to an intelligent sleeper for detecting the state of line quality. Background technique [0002] In recent years, with the continuous speed up of my country's railways, the volume of railway transportation has continued to increase. Concrete sleepers, which are the main components of the railway track structure, are increasingly damaged in various forms such as cracks, falling blocks, and dark pits. Sleeper hanging is one of the most common diseases of ballasted track. Due to the uneven settlement of the foundation, insufficient ballast tamping, long-term impact of the train, and the washing of the ballast by rainwater, the ballast bed will sink, resulting in a decrease in the contact area between the ballast and the sleeper, resulting in the phenomenon of empty sleeper suspension. Empty suspension of sleepers will cause une...

Problems solved by technology

Due to the uneven settlement of the foundation, insufficient ballast tamping, long-term impact of the train, and the washing of the ballast by rain, the ballast bed will sink, resulting in a decrease in the contact area between the ballast and the sleeper, resulting in the phenomenon of empty sleeper suspension

Empty suspension of the sleeper will cause uneven track support stiffness, increase the impact of the wheel and rail, accelerate sleeper damage, ballast pulverization, damage to rails and fasteners, and even affect the safety of train operation

[0003] The railway line has been in a dynamic process for a long time. As an integral part of the railway line, the sleeper bears repeated loads from the rails. The dosage is large. Under the busy working conditions, it is difficult to rectify immediately when minor defects of the line and sleeper are found. This will cause the damage of the sleeper to accumulate, and finally lead to the failure of the sleeper.
