Detailed Description
The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.
Examples
The utility model provides a detection device for rail transit vehicle cross section profile, as shown in figures 1-8, the detection device comprises a column 1, a detection template 4, support plates 2, connecting plates 3, a bidirectional spring hinge 9, a micro-gap switch 8, a control system and a rotary column 6, the shape of the detection template 4 is processed and manufactured according to the given vehicle profile, the column 1 is provided with a plurality of support plates 2, the support plates 2 are all provided with the connecting plates 3, one side of the connecting plates 3 is connected with the support plates 2, the other side of the connecting plates 3 is connected with the detection template 4 through the bidirectional spring hinge 9, the bidirectional spring hinge 9 is provided with the micro-gap switch 8, the micro-gap switch 8 is connected with the bidirectional spring hinge 9 through a micro-gap switch seat 7, the micro-gap switch 8 is provided with a micro-gap switch contact screw 10 and a micro-gap switch contact 12, the micro-, and an indicator lamp controlled by the open or close state of the microswitch 8 is arranged on a panel of the control system. The upright post 1 is actively connected with the track through a rotating upright post 6. In order to detect the accuracy of the data, the number of the microswitches 8 arranged at the left side and the right side of the detection stencil 4 is respectively 8, and the number of the microswitches 8 arranged at the top end of the detection stencil 4 is 4.
