It falls off in hole；The lower end of the pressure sensor is equipped with top flat；The fixinig plate and top flat are on the same line.
The pressure sensor dismantling is convenient can to replace model in practical applications；The top flat of pressure sensor is in positive reason
It is not contacted under condition with the fixinig plate of probe, no external strength acts on pressure sensor, reduces error；Holder when operating
It moves down and drives top flat and fixinig plate contact, and racing track is avenged into ice-like in probe top, the hardness of racing track is different, top flat and fixation
Pressure between piece just changes, and acquires out by pressure data by pressure sensor.
Further, described device further includes pressure gauge；The pressure gauge and pressure sensor are electrically connected.
Further, the top of the sliding rail is additionally provided with balancing pole.
Compared with prior art, the present invention have it is following the utility model has the advantages that
The present invention devises a set of ice-like snow racing track rigidity detection device, and the device is vertical by probe by sliding holder movement
It is pressed into ice-like snow racing track, by extracting the stress curve in process of press in, extracts pressure sensor using numerical method and bear
Load forces as hardness number, will thus be converted to the problem of measurement ice-like snow racing track hardness according to compression curve, and extract pressure
Hardness number of certain several points of force curve as racing track difference snow deposit；
The apparatus structure is firm, dismantling is convenient, installation is simple, carries and measures convenient for snowfield, can be to the ice-like of different-thickness
Snow racing track measures, significantly guarantee race fairness and safety.
