The specific embodiment
To combine accompanying drawing that the utility model is further described below.
Fig. 1 has shown the sectional drawing that is used for steel rail vibration damping device 9 is fixed in the clip 20 on the rail according to the utility model.Rail comprises rail head 10, the web of the rail 11 and the flange of rail 12.As shown in the figure, shock absorber 9 is installed at least a portion zone of the web of the rail 11 and the flange of rail 12 of rail, and is fixed on the rail through clip 20 (its structural representation is as shown in Figure 2).Clip 20 for example can be made of metal to band shape.
As shown in the figure, clip 20 comprises fitting tightly and links to each other in first clamping section 13 on the bottom surface of the rail flange of rail 12, with first clamping section 13 and be pressed on second clamping section 14 on the side of steel rail vibration damping device 9, link to each other with second clamping section 14 and be pressed on the 3rd clamping section 15 on the end face of steel rail vibration damping device 9.On the free end of said first clamping section 13, be provided with the crotch section 16 that matches with the side of the rail flange of rail 12.
According to the utility model, first clamping section 13 of clip 20 is provided with the U-shaped elasticity knot 17 to outer process.This elasticity is become clip provides certain elasticity, is convenient to the installation or removal of clip.As shown in Figure 1, in a preferred embodiment of the utility model, U-shaped elasticity knot 17 is located at axis with respect to rail and is in a side identical with second clamping section 14.In a unshowned embodiment, U-shaped elasticity knot 17 preferably is located in the orthography zone of the 3rd clamping section 15 on first clamping section 13.In these two kinds of preferred set-up modes, U-shaped elasticity knot 17 can make the fixation of clip 20 more firm relatively away from the free end of first clamping section 13 like this, is difficult for loosening.Simultaneously, the active force of U-shaped elasticity knot 17 after elastic deformation strengthened the clamping force that the 15 pairs of steel rail vibration damping devices in second clamping section 14 and the 3rd clamping section apply.
According to the clip of the utility model, preferred first clamping section 13 is connected through arc-shaped transition part 18 with second clamping section 14.In addition, second clamping section 14 preferably is connected through another arc-shaped transition part 19 with the 3rd clamping section 15, and is as depicted in figs. 1 and 2.It is smooth and easy more naturally that the connected mode of this two places arc-shaped transition makes that the each several part of clip connects, and also for clip provides elasticity on the whole, helps the installation and removal of clip, and help strengthening fixed effect.
According to the clip of the utility model in use; At first place shock absorber 9 on the zone of the web of the rail 11 and the flange of rail 12 of rail; Then with first clamping section 13 of clip 20 from its bottom surface that a side of the rail flange of rail 12 is passed; Touch the end of an other side of the rail flange of rail 12 until the free end of first clamping section 13, simultaneously the 3rd clamping section 15 is pushed down the end face of shock absorber 9, this moment, clip 20 roughly entangled shock absorber 9 and rail.Through for example applying external force in the junction of first clamping section 13 and second clamping section 14 (the for example arc-shaped transition part 18 among the figure); For example use hammer laterally to knock; Apply horizontal power for clip 20, thereby make first clamping section, 13 free-ended crotch sections 16 fasten the end sides of the rail flange of rail 12 other sides through the distortion of U-shaped elasticity knot 17.At this moment, clip 20 intrinsic elasticity make its 3rd clamping section 15 apply downward pressure to shock absorber 9, and first clamping section 13 applies to rail and upwards pressure accordingly; Second clamping section 14 is to shock absorber 9, first clamping section, 13 free-ended crotch sections 16 corresponding pressure about rail applies respectively, thereby shock absorber 9 firmly is fixed on the rail.
In a preferred embodiment of the utility model, second clamping section 14 is curved, and compresses the side of steel rail vibration damping device 9 through the projection of said arc.More preferably, the 3rd clamping section 15 is curved, and compresses the end face of steel rail vibration damping device 9 through the projection of said arc.The contact surface of arc can make the force localization of clip to shock absorber, increases pressure, improves fixed effect.
Preferably, the clip surface according to the utility model is provided with diaphragm (not shown in the accompanying drawing).Diaphragm can make clip avoid damaging or corrosion, increases the service life.
Above reference preferred embodiment the utility model is described, but the protection domain of the utility model is not restricted to this, all technical schemes in any scope that falls into claim are all in the protection domain of the utility model.
