3, because damping block and bracing frame are by assembling, therefore be easy to dismounting and change, only need changing damping block during repair and replacement, thereby reduce use cost greatly.
Description of drawings
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, wherein:
Fig. 1 is the floating rail type track vibration-reducing device vertical view of the utility model one embodiment.
Fig. 2 is that floating rail type track vibration-reducing device A-A embodiment illustrated in fig. 1 is to sectional view.
The specific embodiment
Fig. 1 is the floating rail type track vibration-reducing device vertical view of the utility model one embodiment.Fig. 2 is that floating rail type track vibration-reducing device A-A embodiment illustrated in fig. 1 is to sectional view.Shown in seeing figures.1.and.2, two fixation kits that the shock absorber of present embodiment comprises base plate 5, two bracing frames 2, two damping blocks 1, is made up of fixed stop 4, contiguous block 3 and lock bolt 7, and flange of rail vibration attenuation pad 6.Wherein base plate 5 is located at the below of the rail 10 of track, as the basis of whole vibration damper.Two bracing frames 2 symmetry respectively are placed on rail 10 left and right sides, each bracing frame 2 has support portion 2a and adjutage 2b, each support portion 2a is used to install damping block 1, and the self-corresponding support portion 2a of each adjutage 2b extends on the base plate, and the last installed surface of adjutage bottom surface and base plate is complementary.When installing in mode shown in Figure 2, two damping blocks 1 will withstand the two side of rail 10, and the support by two bracing frames 2 makes rail 10 be floated on base plate 5 tops.
Each bracing frame 2 is fixed by fixation kit, and fixing mode is described below.The both sides of base plate 5 respectively are provided with groove.Fixed stop 4 is roughly inserted in the groove of base plate 5 both sides by the middle position of base plate 5, and can be pushed into the bottom and finally be arranged in the groove that is located at base plate one side with the right side to the left respectively.The fixed stop 4 of shifting the position onto will be relative with the adjutage 2b of the bracing frame of respective side, and a space is arranged between the two.Contiguous block 3 is inserted between the adjutage 2b and fixed stop 4 of a bracing frame, then with a lock bolt 7 with the contiguous block 3 vertical base plates 5 that lock onto.
The outside of each adjutage 2b (promptly relative with fixed stop 4 side) is one section first outward-dipping from top to bottom inclined-plane.Correspondingly, the inboard of each fixed stop 4 (promptly relative with an adjutage 2b side) is one section intilted from top to bottom second inclined-plane.The space that forms between these two inclined-planes is just by contiguous block 3 insertions of wedge.Wherein, the inboard of contiguous block 3 can cooperate with first inclined-plane of support arm, and the outside can cooperate with second inclined-plane of fixed stop 4, and middle through hole then inserts lock bolt 7.In one embodiment, first inclined-plane of adjutage is the tilted cylindrical envelope face, is used for cooperating with contiguous block 3.
The T-slot of base plate is put into and be pushed into to lock bolt 7 from the most inboard square through hole of base plate 5, make it the vertical contiguous block 3 that passes, with the supporting nut check other end, thereby the vertical locking of realization contiguous block 3 and base plate 5, and then the whole vibration damper assembly is laterally also realized locking.Bolt head can be designed to square, and bolt rotates in the base plate T-slot and makes assembly loosening in the time of can preventing to be subjected to load.
In one embodiment, comprise that also a flange of rail vibration attenuation pad 6 is installed in the base plate central groove, when rail 10 was subjected to big greater impact load and impacts displacement to surpass the spacing of shock absorber and rail design, rail 10 contacted with flange of rail vibration attenuation pad 6, and this moment, backing plate played suitable cushioning effect.
Present embodiment is used for reference the principle of shearing-type shock absorber, with bracing frame and damping block rail is suspended, and when rail carries, provides elasticity thereby shear strain will take place the damping block that install the side.
Comprehensive the above, present embodiment is by structural reasonably optimizing, to design and can satisfy the high-performance vibration reduction device that track traffic is used. the vertical quiet rigidity of present embodiment can reach 4～6KN/mm, the output ratio of Q-switching to free running can reach below 1.6, vibration isolating effect is improved, basic suitable with the plate isolation mounting of floating, allow rail that bigger vertical deviation is arranged simultaneously; Because the lateral support of shock absorber guarantees that the rail corner does not transfinite, and does not increase the overall height of rail; The optimal design of contiguous block and bracing frame has guaranteed the stressed even of rail, and vertically holding capacity has strengthened, and the cross-protection ability also is improved, and has realized that the free adjustment of gauge and locking are more reliable; Because damping block and bracing frame are by assembling, therefore be easy to dismounting and change, only need changing damping block during repair and replacement, thereby reduce use cost greatly.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
