3, test job cumbersome, take a lot of work, time-consuming, and testing staff's technical merit is required high.When locomotive overhauls in locomotive depot, carry out in trench with the need of work of this gage measuring wheel tread physical dimension, light is very poor, during detection, needs flashlight lighting, measures observed reading again, recording card again, and operation is trouble very.

4, the computer management requirements of one's work in the incompatibility locomotive depot.Carry out computer management in China railways locomotive depot, executing state is repaiied in locomotive maintenance work.Therefore, every day must be measured 5-8 platform locomotive, and the physical dimension situation of 72-96 wheel in time by manually importing to microcomputer, make mistakes by very cumbersome cutting easily.

In view of the problem that prior art exists, the purpose of this utility model provide a kind of realization the " TB1360-80 locomotive wheel detector " defined whole test functions, the location is reliable, survey precision is high, easy to use, can and the gauge head of the locomotive wheel electronics detector of management computer networking.

Portable locomotive wheel electronics detector gauge head is to constitute like this, it is made up of the flange thickness survey chi, tread wear measurement chi, tire thickness survey chi, wheel rim backup plate, the location angle bar that are fixed on the mainboard, and its flange thickness surveys chi (2) and tread wear measurement chi (3) is a volume grate electronic digital display displacement sensor; Wheel rim backup plate (5) is a V-structure.

The advantage that the utility model is compared with prior art had is:

1, owing to adopted high-precision volume grate electronic digital display displacement sensor to replace vernier to survey chi, the high grade of its precision.Therefore, the measuring accuracy height satisfies the accuracy requirement of measured size fully; Can automatically locate guaranteed discharge to have the tram because of the registration device on the electronics gauge head again, thereby avoid using the manual operation error that has measurer now, further improve measuring accuracy with measured object;

2, easy to operate, quick, high efficiency.In test process, can realize, need not throw light on and make a copy of form, the test of a wheel is only needed the 2-3 time in second.

3, can realize and satisfy the needs of locomotive depot of railway system computer management.After surveying work is finished, only need electronics main frame and management computer are directly networked, just can be measured total data, in the requirement input microcomputer by the engineering Administration menu.The trouble and the operation mistake of artificial input have been avoided.
