Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
With reference to Fig. 2, gapless sky rail track beam telescoping device of the invention includes being respectively and fixedly installed to expansion joint L both sides
Left side fixed plate 20, right side fixed plate 21 on 10 end of track girder and mounted on left side fixed plate 20 and right side fixed plate
On 21 and the movable plate of plate face flush 22.With reference to Fig. 3 and Fig. 5, the plate face of the movable plate 22 is in cut the isosceles triangle of point,
There is oblique tongue 26 under the plate face at its two bevel edge positions.With reference to Fig. 3 and Fig. 5, left side fixed plate 20, right side fixed plate 21 have
Have with 22 corresponding bevel edge of movable plate, and in the plate face at bevel edge position there is oblique groove 26, set on oblique groove 26
Its axis kidney-shaped guide groove 27 that diagonally 26 length direction of groove extends.With reference to Fig. 2, two of the movable plate 22 are oblique convex
Slot 26 matches to form sliding friction pair with the oblique groove 26 of left side fixed plate 20, right side fixed plate 21 respectively, movable plate 22
Upper fixed setting its underpart passes through the guide pin 23 of kidney-shaped guide groove 27.When flexible become occurs for the track girder 10 of expansion joint L both sides
During shape, left side fixed plate 20, right side fixed plate 21 generate longitudinal movement, and act on movable plate with the linear deformation of track girder 10
