Description
Technical field
The present invention relates to railway transportation equipment technical field, and in particular to a kind of derailing based on adapter positioning detects dress
Put and its detection method.
Background technology
Train derailing is the operating great driving accident of rail truck.The generation of derailment accident, vehicle, goods will be caused
The damage of thing, transit equipment and communication apparatus, life will be also injured when serious, therefore paid much attention to by countries in the world.From
After China railways speed-raising in 1997, goods train derailing is on the rise；Nearly l0, derailment accident are driven a vehicle in China railways
Ratio in great, major break down is up to 70% or so.To ensure safety of railway traffic, the countermeasure of strick precaution is found out, lorry is reduced and takes off
Rail accident is an important and pressing task.
The reason for causing derailment accident is more complicated, that is, has human factor, apparatus factor, also natural calamity etc..Derailing
Accident can greatly reduce after train operation performance is improved, strengthen staff quality and safety education, but can not possibly prevent completely,
Because irresistible natural calamity is one of the main reason for causing derailing.
Though derailing is inevitable, can increase on vehicle after Derail detector reaches early warning before derailing and derail
Brake the effect of detraction.At present, derail braking technology comparative maturity, and the carriage derailment automatic arresting device that Nan Che companies develop is wide
The general 70t levels that are applied to are with Truck, significant effect；Relative, it can realize that the derailing detection technique of warning function also can not
Put into and use by product.Current rail parent company has begun to the development work of tissue red ball, and Jinzhong City's south heavy carrying coal is special
Line also uses input, and the fast freight heavy duty requirements of railway freight-car are more and more urgent, and realize one of key technology of these targets
Exactly prevent vehicle derailing.But be currently directed to derailing problem main development is derailing braking technology, has derailing early warning work(
The product of energy because technical difficulty is big, has no scale successful case, still in the market vacancy phase, it is latent also in experimental stage
Power and value are very huge.Therefore it is the research topic being significant to develop Derail detector and detection method.
The content of the invention
It is an object of the invention to provide a kind of Derail detector and its detection method based on adapter positioning, realize
Warning function before rail truck derailing, solves the problems, such as the unpredictable derailing of rail truck, to ensure safety of railway traffic, subtracts
Few freight car deraicment accident provides guarantee.
To achieve the above object, the Derail detector based on adapter positioning designed by the present invention, is symmetrically arranged on
Towards the side of wheel (6) on four adapters (1) on bogie, it is characterized in that：It include four bearing supports and

The installation base surface is further opened with mounting hole, for installation base surface to be fixed on to the adapter of bogie towards wheel
Side, after the bearing support installation, the wheel shaft of bogie is located inside the frame structure of bearing support；
The laser displacement gauge presss from both sides with processor system installed in the acute angle that the oblique connecting rods are connected with horizontal brace rod
At angle, and the laser displacement gauge is located at directly over railway track with processor system, so as to for measuring wheel relative to iron
The Uplifting amount of road rail, and data processing and judgement are carried out according to Uplifting amount.
Preferably, the installation base surface of the bearing support is fixedly installed on the adapter towards car by rivet or bolt
The side of wheel.
Preferably, the processor of the laser displacement gauge and processor system is single-chip microcomputer.
Further, the quantity that the installation base surface opens up mounting hole is four.
Further, the center of circle corresponding to the arc-shaped connecting rod and the cross section center of circle of wheel shaft overlap, and the arc connects
The radius of circle corresponding to extension bar is 110-120mm.
In addition, the present invention also provides the detection method of above-mentioned Derail detector, it is characterized in that：Including following step
Suddenly：
1) laser displacement gauge is started shooting with processor system (3), and laser displacement gauge distance in itself is gathered by laser displacement gauge
The vertical range data of rail (5) upper surface, the data of the m times collection are designated as Hm；The average value of data is calculated by processor
As the datum mark of this measurement, H is designated as0；
2)HmWith H0Ask poor, that is, it is h to obtain wheel (6) relative to the Uplifting amount of rail (5)m=Hm-H0, sentence for performing
It is disconnected；
