The invention relates to a parameter detection device for a track vehicle steering frame, in particular to a closed adjustable thrust gantry device. The device is designed against the status quo that the positioning of the steering frame and a vehicle body of the prior parameter test table of the steering frame is difficult during the testing process, the whole vehicle test can not be realized andthe testing type of the steering frame is single and the like. The device mainly consists of a suspended upper cross beam assembly (I), a lower embedded cross beam (II) and a brace type thrust upright beam assembly (III). The suspended upper cross beam assembly (I), the lower embedded cross beam (II) and the brace type thrust upright beam assembly (III) are connected to a closed whole body by thebolt connection way. The device provides a technical means for positioning the steering frame, positioning the vehicle body and testing the whole vehicle for the steering frame of the track vehicle during the parameter testing process, has the functions of the swing-type steering frame test and the eccentric load test and realizes the purpose of having a plurality of test functions on one testingdevice. The device has an important role for accelerating the upgrade and replacement process of railway freight car products in China.
