Ferry slide table for rail vehicle bogie parameter detection equipment

technical field

The invention relates to a parameter detection device for a rail vehicle bogie, in particular to a ferry slide device.

Background technique

At present, some bogie parameter test equipment with different functions have been developed at home and abroad, but almost all test equipment are difficult to guide the bogie to the test equipment smoothly, accurately and quickly when testing the bogie, especially the whole vehicle. This brings limitations to the application of various test equipment, especially the test of slewing stiffness has brought serious limitations, such as the various developed by Windhoff Company of Germany, NENCKI Company of Switzerland and American Standard Vehicle Bogie Company (SCT). Similar problems appear in bogie parameter test benches. Internationally, slide table structures are mostly applied to machine tools or other testing equipment, but there is no record of using the ferry slide table device in bogie parameter testing equipment.

Detailed ways

The specific content of the present invention and its implementation will be further described below in conjunction with the illustrations shown in the accompanying drawings. The embodiment listed here is only one kind of implementation of the technical solution of the present invention, but not the only one.

A ferry slide device for rail vehicle bogie parameter detection equipment, mainly composed of a bridge approach groove movable track 2 and a ferry slide carrier 4, said approach bridge groove movable track 2 is two, fixed in parallel On the carrier 4 of the ferry slide, and the lateral spacing can be adjusted; the movable track 2 of the approach bridge groove or the two ends of the carrier 4 of the ferry slide are respectively equipped with connecting mechanisms; the carrier 4 of the ferry slide is fixed on the The civil foundation C adopts movable fit connection.

The movable track 2 of the bridge approach groove is fixedly connected to a plurality of threaded holes with different row pitches arranged in parallel on the carrier body 4 of the ferry slide through bolts and hexagon socket head cap screws.

The connecting mechanism adopts a platform-vehicle connection hook 1, and the hook can be fixedly connected with the bogie test bench and the auxiliary connection parts of the test bench foundation.

The carrier body 4 of the ferry slide is slidably connected with the rolling guide rail fixed on the civil foundation C through the rolling slide seat 3 .

The movable track 2 of the bridge approach groove is equipped with a track wheel chock assembly D, and the track wheel chock assembly D is composed of a track wheel chock 5 and a wheel chock shaft pin 6, and the track wheel chock 5 is placed on the approach bridge groove movable track 2 In the groove, wheel chock shaft pin 6 is coaxially fitted with the shaft hole of track wheel chock 5 and the shaft hole of bridge approach groove movable track 2.

There are a plurality of shaft holes of the groove movable track 2 , which are arranged correspondingly along the axial direction of the groove movable track 2 .
