[0058] A utility model discloses an installation method based on the aforementioned track inspection beam for high-speed integrated inspection trains. The method includes the following steps:

[0059] S1: The pads 25 on the first mounting surface 100 and the second mounting surface 200 on the crossbeam 20, as well as the hoisting area 300, are all machined surfaces to ensure the dimensional tolerance of the installation equipment plane and the dimensional tolerance of the mounting plane between the crossbeam 20 and the hanger 10.

[0060] S2; Bolt 51 is fitted with washer 52 and sleeve 54 in sequence. Elastic element 53 is fitted on the outside of sleeve 54. Bolt 51 is placed in the mounting holes of crossbeam 20 and hanger 10. The top end of elastic element 53 abuts against washer 52 and the bottom end abuts against hanger 10. Sleeve 54 is inserted into the mounting holes of hanger 10, multiple adjusting pads 30 and crossbeam 20 in sequence from top to bottom. Bolt 51 passes through hanger 10, crossbeam 20 and pad 40 at the bottom of crossbeam 20 and then nut 55 is installed. There is a gap between the bottom end of sleeve 54 and pad 40.

An adjustment shim 30 is installed between the crossbeam 20 and the hanger 10. The height can be adjusted according to the actual operating conditions. When removing the adjustment shim 30, a shim 52 of appropriate thickness needs to be added between the rubber block and the sleeve 54. Figure 4 As shown.
