As shown in Figure 2, a kind of track vibration absorber according to the present invention comprise an absorption of vibrations pad 1, rail gripper shoe 2, rail pad 3, one support crab-bolt 4, hold-down nut 5, a lining 6 and an end cap 7.
Absorption of vibrations pad 1 is installed on the well-known gripper shoe 8, and the latter is placed in rail on the paving location on the way of concrete foundations, to realize the secondary vibration absorption function of rail.Absorption of vibrations pad 1 is the rectangular in form of transverse width greater than vertical width, and it is made by thick rubber or low elasticity urethane.Absorption of vibrations pad 1 has anchor hole 1a at two along the opposite bight of diagonal, supports crab-bolt 4 in order to penetrate.In addition, have a pair of location with predetermined space respectively around each anchor hole 1a and regulate pin 1b.The location is regulated pin 1b and is inserted in the pin hole that is formed on around an anchor hole on rail gripper shoe 2 soffits, with strengthen the absorption of vibrations pad support on the crab-bolt 4 stability and and rail gripper shoe 2 between restraint forces.
The rail pad of being made by thick rubber or low elasticity urethane 3 is used to realize first absorption of vibrations function.Rail pad 3 is assemblied among the rail advance expenditure seat 2d of rail gripper shoe 2.Rail pad 3 has lower cut part 3a in its opposite end, and with the both sides of protection rail bottom, the width of notch portion is greater than absorption of vibrations pad 1.
Support crab-bolt 4 and be fixed in the way of concrete foundations, promptly insert among the anchor hole 2a of anchor hole 8a, absorption of vibrations pad 1 and the anchor hole 1a of gripper shoe 8 and rail gripper shoe 2, so that stable connection the between them.In addition, support crab-bolt 4 also as guide rod, when train is depressed rail pad 3, rail gripper shoe 2 and absorption of vibrations pad 1 by rail, and disappear and when making rail pad 3, rail gripper shoe 2 and absorption of vibrations pad 1 upwards return their position, support crab-bolt and can guide rail pad 3, rail gripper shoe 2 and absorption of vibrations pad 1 to move up and down glossily when the dynamic load of train.Support crab-bolt 4 and have a screw thread 4a in the top, and have an anchor portion 4b to insert in the anchor hole that forms perpendicular to way of concrete foundations in its lower end.Strength adhesive is filled in the gap between anchor portion 4b and the anchor hole, so that anchor portion firmly is installed in the way of concrete foundations.
Hold-down nut 5 is meshing the screw thread 4a that supports crab-bolt 4 upper ends, leaves their relevant position to prevent rail gripper shoe 2, absorption of vibrations pad 1 and gripper shoe 8.
Lining 6 is used to prevent that physics contacts between the soffit of upper surface and hold-down nut 5 of anchor hole 2a of rail gripper shoe 2, and arrange up and down by being fixedly mounted on the support crab-bolt 4 on the way of concrete foundations in gripper shoe 8, absorption of vibrations pad 1 and rail gripper shoe 2, then again constantly, keep the rate of tension of rail gripper shoe 2 with hold-down nut 5 and the upper end interlock of supporting crab-bolt 4.Lining 6 is made by rubber or low elasticity urethane.
Perhaps, also can utilize a spring to replace lining 6.
End cap 7 is used to the hold-down nut 5 of protecting and support crab-bolt 4 meshing.End cap 7 has a locking tooth 7a on the periphery within it, and its top since a packing ring 11 moves down the edge thickness that has passed through packing ring, as shown in Figure 2, thereby can prevent that end cap 7 from coming off, unless firmly end cap and hold-down nut 5 are separated.
A still NM rail fixture 9 and a spacing block 10 are identical with structure in the technology formerly in front structure being described.And code reference number 11 one of expression are loaded on the packing ring above the lining 6.
Fig. 3 and 4 is respectively vertical view and the cross-sectional view that has the rail of track vibration absorber according to the present invention.Vertical anchor hole 12a with the concentric axis of anchor hole 8a, 1a and 2a on be formed in the way of concrete foundations 12, to charge into strength adhesive 13.Afterwards, supporting crab-bolt 4 is inserted among the vertical anchor hole 12a.After strength adhesive was solidified, anchor hole 4 promptly was fixedly installed among the vertical anchor hole 12a.Anchor hole 12a is enough dark, thereby can suppress the shake of rail gripper shoe 2, promptly supporting under the situation of crab-bolt 4 normal mounting in way of concrete foundations 12, when gripper shoe 8, absorption of vibrations pad 1, rail gripper shoe 2, lining 6 and packing ring 11 are fixed on the expose portion of the support crab-bolt 4 that is loaded in the concrete 12 and after hold-down nut 5 tightens fully, because because of biting pressure is compressed, so the dynamic load of train can not work between absorption of vibrations pad 1 and the lining 6.
After support crab-bolt 4 installs, among anchor hole 8a, absorption of vibrations pad 1 and the anchor hole 1a of support crab-bolt 4 insertion gripper shoes 8 and the anchor hole 2a of rail gripper shoe 2.Afterwards, lining 6 and packing ring 11 successively are placed on the grappling pipe 2b of rail gripper shoe 2.At this moment, the overall height of gripper shoe 8, absorption of vibrations pad 1, rail gripper shoe 2, lining 6 and packing ring 11 is greater than the following boundary line of the screw thread 4a that supports crab-bolt 4.Yet because the engagement by hold-down nut 5 makes the high flexibility of absorption of vibrations pad 1 and lining 6 reduce, so rail gripper shoe 2 can be by suitable pressure compression, thereby prevents the shake of rail gripper shoe 2.
At this moment, by regulating the thickness of gripper shoe 8, height error that can the compensating concrete roadbed.
After hold-down nut 5 was meshed fully, rail pad 3 was placed on the rail advance expenditure seat 2d of rail gripper shoe 2 securely.At this moment, rail pad 3 is contacting the two opposite sides of rail gripper shoe 2 with its lower cut part 3a.
At last, end cap 7 is applied on the hold-down nut 5, to protect hold-down nut 5 and good appearance is provided.In addition, because the existence of locking tooth 7a, end cap 7 is difficult for coming off from hold-down nut 5.Therefore, hold-down nut 5 is difficult for unclamping.
Foregoing absorption of vibrations pad 1 is used for the initial construction of rail, and absorption of vibrations pad 5 shown in Figure 5 then is used to repair rail.When the old absorption of vibrations pad 1 after need be with one the tired time limit finishes is replaced by new absorption of vibrations pad, need unclamp hold-down nut 5, extract rail gripper shoe 2 again out, so that change absorption of vibrations pad 1.Yet this replacing incurs great expense, consumes plenty of time and very inconvenience.
To change these shortcomings that the rail pad causes in order eliminating, a kind of new method need to be provided, it can easily change absorption of vibrations pad 1 under rail 14 is laid on the situation of way of concrete foundations, and does not need to extract out other element.The absorption of vibrations pad 1-1 that is used to repair and 1-2 shown in Figure 5 is divided into main body 1-1 and bight 1-2 by the boundary line, and this boundary line linear incision is on lateral edges and leading edge or lateral edges and back edge, to regulate the position that pin 1b inwardly is separated by through associating.
When needs are replaced by replaceable absorption of vibrations pad 1-1 and 1-2 with absorption of vibrations pad 1, have only a few rail fixture from the fixing hole of rail gripper shoe 2, to extract out in the track vibration absorber, to lift the rail that needs replacing.End cap 7 unloads so that change from rail, and hold-down nut 5 is unclamped aptly so that take out absorption of vibrations pad 1 afterwards.Next, lift rail gripper shoe 2, to obtain to take out absorption of vibrations pad 1 and the new required space of absorption of vibrations pad of insertion by a lever or hydraulic jack.Afterwards, old absorption of vibrations pad 1 is removed, and the main body 1-1 of new absorption of vibrations pad is inserted by the downside surface from rail gripper shoe 2, and insert from left and right sides respectively in the bight 1-2 of new absorption of vibrations pad, and afterwards, rail returns initial position.Because regulate the effect of pin 1b, the main body 1-1 and the bight 1-2 of new absorption of vibrations pad can not deviate from.
No matter be absorption of vibrations pad 1 or 1-1, under the situation that rail 14 is laid as shown in Figure 2, when train passed through rail, the dynamic load of train all can be absorbed by rail pad 3 earlier before being delivered to rail gripper shoe 2.Yet unabsorbed dynamic load will be delivered to rail gripper shoe 2.Under the dynamic load effect that is delivered on the rail gripper shoe 2, rail gripper shoe 2 can descend a bit under the guiding of supported crab-bolt 4.Absorption of vibrations pad 1 and 1-1 is depressed by rail gripper shoe 2, to realize the secondary absorption function.
After having passed through the secondary absorption, the vibration that causes because of the train dynamic load can be delivered on the way of concrete foundations 12 hardly.In case train has passed through, rail gripper shoe 2 promptly can upwards be returned under the effect of the restoring force of absorption of vibrations pad 1.Consequently, rail 14 can return initial position under the effect of the restoring force of the restoring force of above-mentioned absorption of vibrations pad and rail pad 3.
As mentioned above, for this track vibration absorber, it moves up and down is freely to carry out, because rail gripper shoe 2 is when being subjected to dynamic load, it can descend under the guiding of supporting crab-bolt 4, and after the dynamic load disappearance that is delivered on the rail gripper shoe 2, rail gripper shoe 2 can upwards be returned, thereby has prevented seesawing and side-to-side movement and unequal sinking of it fully.Consequently, can not make that the train was derailed.
Used light load anchor bolt (φ 26mm) in the track vibration absorber according to technology formerly, they need frequent replacing in humid climate.On the contrary, track vibration absorber according to the present invention has good durability, because used two bigger anchor bolts (φ 40mm) in the shock arrester (-tor).
Specifically, if the thickness of absorption of vibrations pad is enough, then can make the shock absorption maximization, this is because the rail gripper shoe with support crab-bolt stable occlusion.In addition, can improve the durability of way of concrete foundations and train, and improve passenger's impression aboard.
In addition, by by main body with comprise the absorption of vibrations pad (Fig. 5) that the bight constituted of an anchor hole part, can the absorption of vibrations pad out-of-date or impaired after change them easily, therefore keep in repair the absorption of vibrations pad easily, and can reduce expense, the replacing time and the manpower consumption of involving vibrations absorption pad.
In addition, with comparing according to the track vibration absorber of technology formerly, owing to have only end cap and rail fixture to expose, so can form outward appearance preferably, and reduce size and weight.
