Description
Technical field
The utility model relates to the suspension sensor in the levitation gap test macro of magnetic suspension train.
Background technology
The magnetic suspension train of having succeeded in developing in the world at present has three types: the MLX series (at a high speed) of the TR series (at a high speed) of Germany, Japan, the HSST series (low speed) of Japan.The most essential difference of all magnetic suspension trains and wheel-rail train is exactly that it has suspension control system, thereby makes the train can deorbit.The suspension sensor is the important component part of suspension control system, it is used to test the levitation gap of train with respect to track, and signal imported treater in the suspending chopper, signal according to the suspension sensor, change the electric current that the available voltage that is added in the levitating electromagnet two ends changes levitating electromagnet by suspending chopper, thereby regulate the attractive force of levitating electromagnet, make the train hoverheight stable the steel guide rail.Therefore, the precision of suspension sensor output signal and reliability directly influence the suspension precision and the reliability of train.Because the suspension working sensor is in the environment of high-voltage large current, its fault rate height.Thereby, develop highly reliable suspension sensor, for the reliability that improves suspension control system, improve the suspension effect of train, be extremely important.
The utility model content
The purpose of this utility model just provides a kind of magnetic suspending train sensor, this suspension sensor accuracy height, good reliability, Highgrade integration, take up room little, convenient for installation and maintenance, long service life.
The utility model solves its technical matters, the technical scheme that is adopted is: a kind of magnetic suspending train sensor, comprise gap probe, gap probe wire, acceleration pick-up, acceleration pick-up lead, its constructional feature is: gap probe, acceleration pick-up are three, three gaps probe and three acceleration pick-ups are installed on the mount pad one by one along the strip shape groove of strip shape mount pad, are fixed with the seal cover cap that covers gap probe and acceleration pick-up on the mount pad.
Compared with prior art, the beneficial effects of the utility model are: the data that three gaps probe and three acceleration pick-ups are independently measured are imported the suspension control system treater simultaneously and are handled, utilize three groups of data to carry out being used for after the analytical calculation hoverheight control of magnetic suspension train simultaneously, can improve the Suspension Control precision and the accuracy of magnetic suspension train effectively.The more important thing is: because three groups of independently take off data are arranged, when a certain probe or sensor failure, the control system treater can be analyzed, judge in these three groups of data and abnormal data occur, provide the cue of repair and replacement sensor on the one hand, on the other hand this misdata is abandoned; Owing to only utilized normal data, can avoid misdata to be used, it is unstable that train is suspended, even the situation that has an accident, thus the suspension reliability and the safety thereof that have improved magnetic suspension train.Gap probe and acceleration pick-up are installed in the mount pad integratedly, can maximally utilise the inner space of mount pad, obviously reduce the oad of whole sensor, save the space, convenient for installation and maintenance, time of setting up, manufacturing and maintenance cost are low; Probe and sensor are installed in the interior seal cavity of mount pad and seal cover cap, also make its reliability height, long service life; Integrated mounting means can reduce simultaneously.
Above-mentioned seal cover cap top has and the adaptive probe hole of gap probe size over against the position of gap probe, and this tapping is furnished with the identical probe capping of being made by epoxy plate of size, and seal cover cap and probe capping use insulating adhesive bonding between the two.
Because the spacing between train bottom and train rail is less; limited the thickness of whole sensor; the probe capping of adopting epoxy plate to make at the probe place can be done thinlyyer; thereby can guarantee the installing space of gap probe in mount pad; make again gap probe can in-plant detection the gap of itself and track; also can protect simultaneously the gap probe not to be subjected to the infringement of external environments such as extraneous dust, rainwater, improve the precision and the reliability of its detection, and prolong its service life.
This above-mentioned mount pad adopts aluminum alloy to make, and seal cover cap adopts the fine cloth bakelite board to make, and is provided with packing seal between mount pad and the seal cover cap.
Except that mount pad, all the other each parts all adopt non-metallic material to make, and have alleviated the overall weight of sensor, are convenient to installation and maintenance; And seal cover cap and probe capping adopt non-metallic material to make, and make the interference of sensor and interorbital signal transmission little.Between seal cover cap and mount pad, packing seal is set, makes, can reach well dustproof, waterproof effect by silaatic.
Above-mentioned gap probe wire, the acceleration pick-up lead end along same direction from mount pad is drawn; Draw the end at this of mount pad and have probe wire hold down groove and sensor conductor hold down groove; Respective fixation has probe wire permanent seat and the sensor conductor permanent seat of being made by silaatic in two hold down grooves; Gap probe wire and acceleration pick-up lead pass from probe wire permanent seat and sensor conductor permanent seat respectively.
Sensor conductor permanent seat, probe wire permanent seat can degree of will speed up sensor conductor and the gap probe fix and sealing, with the wearing and tearing of minimizing lead.Simultaneously, lead can directly be drawn from this suspension sensor internal, reduces the connecting link of lead, reduces signal attenuation, further improves the precision of suspension sensor.
Have probe wire groove, sensor conductor groove on the bottom of above-mentioned mount pad groove and the groove shoulder, gap probe wire, acceleration pick-up lead place the bottom of probe wire groove and sensor conductor groove respectively, and butyl rubber or foamed silica gel are pressed in the top of gap probe wire, acceleration pick-up lead then embedding.Can further prevent gap probe wire and the wearing and tearing of acceleration pick-up lead in train travelling process like this, improve the service life of suspension sensor.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
