A Bolt Loose Detection and Alarm Device for Connecting Parts of Rail Joints

Abstract

The invention relates to a bolt looseness detection and alarm device for a rail joint connecting component, which comprises a steel wire and a bolt looseness detector, wherein one end of the steel wire is welded at the head of a bolt of the rail joint connecting component, the other end is connected with a negative electrode wire of the bolt looseness detector, the bolt looseness detector is installed at the surface, which is away from the rail, of a clamping plate, located between two adjacent through holes on the clamping plate and used for detecting the looseness of the bolt and reminding railway workers of the looseness of the bolt, the steel wire connects the head of the bolt of the rail joint connecting component and the bolt looseness detector together, a pulling force is generatedfor the steel wire when the bolt gets loose, the pulling force of the steel wire enables an output value of a looseness sensor of the bolt looseness detector to be changed, and a main control board judges a loosened bolt according to a variation value of the looseness sensor and turns on an indicator lamp at the same time to give an alarm to the railway workers.

Description

technical field [0001] The invention relates to a bolt looseness detection and automatic alarm device on rails, in particular to a bolt looseness detection and alarm device for rail joint joint parts. Background technique [0002] The rail joint refers to the structure that the rails on the track are connected by splints and bolts so that the train can run continuously. The wheel-rail dynamic effect at the rail joint is large, and the maintenance and repair workload is large, which is one of the weak links of the track structure. As the wheels that guide the rolling stock, the rails are subjected to tremendous pressure on the wheels, and as the vehicles pass by, the corresponding rails will also vibrate. When the rails vibrate, the connecting parts of the rail joints will also vibrate accordingly. The bolts connecting the parts loosen, causing the rail joint to shift, and in severe cases, it will cause the train to climb the rail accident. [0003] In the prior art, the ra...

As the wheels that guide the rolling stock, the rails are subjected to tremendous pressure on the wheels, and as the vehicles pass by, the corresponding rails will also vibrate. When the rails vibrate, the connecting parts of the rail joints will also vibrate accordingly. The bolts connecting the parts loosen, causing the rail joints to shift, and in severe cases, it will cause a train climbing accident

[0003] In the prior art, the railway workers found the loose bolts of the rail joint joint parts from the abnormal sound after hitting the rails with a hammer, that is, when the railway workers hit the rails with a hammer, the loosening of the bolts changed the structure of the subtle parts of the object, then According to the different timbres of their sounds, it can be judged whether the bolts of the rail joint connecting parts are loose. However, this detection method not only has a large workload and a high false detection rate, but also needs to frequently detect the looseness of each rail joint connecting part. bolt
